Description
塔机引进平台结构 技术领域 本发明涉及工程机械领域， 特别是一种塔机引进平台结构。 背景技术 现有的动臂塔机， 特别是中小型号动臂塔机， 在顶升加节过程中多采用下引进方 式。 由于动臂塔机的引进角度一般在 84° 〜86° 之间， 在臂架长度较长的情况下， 引 进标准节时， 吊钩距塔身中心的距离远， 因此， 要求引进平台外伸长度必须较长， 从 而造成动臂塔机在大角度 （小幅度） 工作时， 吊钩易与引进平台干涉， 影响塔机有效 工作范围和使用安全性。 同时， 与锤头塔和平台塔不同， 动臂塔机不同臂长的引进幅度各不相同。 在短臂 长情况下， 塔机的引进幅度相应减小， 对引进平台的外伸长度要求相应降低， 此时， 外伸长度大的引进平台并不适用， 对塔机工作范围影响更为严重， 且引进平台外形尺 寸过大， 安装运输不便， 运输成本高。 图 1中示出了现有技术中的一种引进平台结构， 引进平台结构包括单引进平台 21 和拉杆 22， 其上有由型钢组成的轨道供引进小车行走。 该方案的缺点是： （1 ) 单引进 平台 21由单平台组成，其外伸长度在塔机正常工作过程中不可变化，在臂架大角度（小 幅度），特别是短臂长情况下， 吊钩容易与平台干涉，既影响动臂塔机的有效工作范围， 也存在安全隐患， 影响动臂塔机使用安全性。 （2) 引进平台 21尺寸大， 刚度小， 运输 不方便。 图 2中示出了现有技术中的另一种引进平台结构。 该引进平台结构在图 1中的引 进平台的基础上改进， 包括内引进平台 23、 外引进平台 24、 长拉杆 25和短拉杆 26 组成， 夕卜引进平台 24和内引进平台 23间用销轴 27铰接。 顶升结束后， 外引进平台 24可向上翻转。 该方案的缺点是： （1 ) 引进平台的外引进平台 24部分虽然可以翻转， 但是缺少相应的翻转辅助装置， 翻转不方便， 翻转速度不可控， 易造成平台晃动， 高 空作业时存在安全隐患。 （2) 引进平台外伸长度虽然可以缩短， 但缩短的长度固定， 在短臂长情况下， 引进平台外伸长度仍然较长 (为便于翻转， 其外引进平台 24相对较 短)， 大角度工作时， 吊钩仍可能与平台干涉。
发明内容 本发明提供一种塔机引进平台， 以防止吊钩和平台的干涉， 减少安全隐患， 同时 可以减小引进平台的尺寸， 便于使用和运输。 本发明通过如下技术方案实现： 一种塔机引进平台结构， 包括： 引进平台， 具有 与塔机主体铰接的铰接部； 拉杆， 第一端与塔机主体连接， 第二端与引进平台连接； 翻转提升机构， 驱动连接引进平台， 使引进平台绕铰接部翻转。 进一步地， 引进平台包括外引进平台和内引进平台， 外引进平台与内引进平台可 拆卸地连接。 进—步地， 外引进平台与内引进平台螺栓连接或销轴连接。 进—步地， 拉杆为柔性。 进—步地， 拉杆由多节杆组成。 进—步地， 多节杆之间枢接连接。 进—步地， 翻转提升机构固定连接塔机主体， 通过钢丝绳驱动连接引进平台 进—步地， 引进平台上设有小车固定耳板。 进—步地， 内引进平台远离塔机主体的一端设有行程限位板。 进—步地， 行程限位板可拆卸。 通过上述技术方案， 本发明的主要优点是， （1 ) 组合式可翻转引进平台具有翻转 提升机构， 平台翻转方便、 省力， 翻转速度稳定、 可控， 可以有效减少平台翻转时产 生的冲击力， 提高操作安全性。 （2) 刚性引进平台可通过整体翻转和分解组合两种方 式缩短引进平台外伸长度， 能有效扩大塔机工作范围， 提高塔机适用安全性。 同时， 外引进平台可拆卸， 内引进平台可单独工作， 对不同臂长情况的适用性强。 （3 ) 刚性 引进平台可拆卸组装方式， 安装运输方便， 可减少运输成本； 同时， 引进结构简单， 易于推广。 附图说明 构成本发明的一部分的附图用来提供对本发明的进一步理解， 本发明的示意性实 施例及其说明用于解释本发明， 并不构成对本发明的不当限定。 在附图中：

本发明的可翻转塔机引进平台的工作过程是: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of construction machinery, and more particularly to a platform structure for a tower crane. BACKGROUND OF THE INVENTION Existing boom tower cranes, especially small and medium-sized boom tower cranes, adopt the following introduction mode during the jacking and adding section. Since the introduction angle of the boom tower crane is generally between 84° and 86°, when the length of the boom is long, when the standard section is introduced, the hook is far from the center of the tower body. Therefore, it is required to introduce the platform extension. The length must be long, so that when the boom tower crane works at a large angle (small amplitude), the hook easily interferes with the introduction platform, affecting the effective working range and safety of the tower crane. At the same time, unlike the hammer tower and the platform tower, the introduction range of the different arm lengths of the boom tower crane is different. In the case of short arm length, the introduction range of the tower crane is correspondingly reduced, and the external elongation requirement of the introduction platform is correspondingly reduced. At this time, the introduction platform with large external elongation is not applicable, and the impact on the working range of the tower crane is more serious. Moreover, the size of the imported platform is too large, the installation and transportation are inconvenient, and the transportation cost is high. An introduction platform structure in the prior art is shown in FIG. 1. The introduction platform structure includes a single introduction platform 21 and a tie rod 22, and a track composed of a profile steel is provided for the introduction of the trolley. The disadvantages of this scheme are: (1) The single introduction platform 21 consists of a single platform, and its outer elongation cannot be changed during the normal operation of the tower crane. In the case of a large angle of the boom (small amplitude), especially in the case of short arm length, The hook is easy to interfere with the platform, which not only affects the effective working range of the boom tower crane, but also has potential safety hazards, which affects the safety of the boom tower crane. (2) The introduction platform 21 is large in size, small in rigidity, and inconvenient to transport. Another introduction platform structure in the prior art is shown in FIG. The introduction platform structure is improved on the basis of the introduction platform in Fig. 1, including the internal introduction platform 23, the external introduction platform 24, the long tie rod 25 and the short pull rod 26, and the introduction platform 24 and the inner introduction platform 23 are used for the pin shaft. 27 hinged. After the jacking is over, the outer introduction platform 24 can be turned upside down. The shortcomings of this scheme are as follows: (1) Although the introduction part of the introduction platform of the platform can be reversed, but the corresponding flipping auxiliary device is lacking, the flipping is inconvenient, the flipping speed is uncontrollable, and the platform is easily shaken, and there is a safety hazard in working at height. (2) Although the elongation outside the introduction platform can be shortened, the shortened length is fixed. In the case of short arm length, the elongation outside the introduction platform is still long (to facilitate the flipping, the introduction platform 24 is relatively short), large angle When working, the hook may still interfere with the platform. SUMMARY OF THE INVENTION The present invention provides a tower crane introduction platform to prevent interference between the hook and the platform, reduce safety hazards, and at the same time reduce the size of the introduction platform, and is convenient to use and transport. The invention is realized by the following technical solution: a tower crane introduction platform structure, comprising: an introduction platform, having a hinge portion hinged with the main body of the tower crane; a drawbar, the first end is connected with the main body of the tower crane, and the second end is connected with the introduction platform; The lifting mechanism is turned over, and the driving connection is introduced to the platform, so that the introduction platform is turned around the hinge. Further, the introduction platform includes an external introduction platform and an internal introduction platform, and the external introduction platform is detachably connected with the internal introduction platform. Further, the external introduction platform is bolted or pinned to the internal introduction platform. Further, the drawbar is flexible. Further, the drawbar is composed of a multi-section rod. Step by step, the multi-rod is pivotally connected. In the step-by-step manner, the hoisting mechanism is fixedly connected to the main body of the tower crane, and the platform is introduced through the wire rope drive connection, and the platform is provided with a trolley fixing ear plate. Step by step, the end of the introduction platform away from the main body of the tower machine is provided with a travel limit plate. Further, the travel limit plate is detachable. Through the above technical solutions, the main advantages of the present invention are: (1) The combined reversible introduction platform has a flip lifting mechanism, the platform is easy to turn over, labor-saving, and the turning speed is stable and controllable, which can effectively reduce the impact force generated when the platform is turned over. Improve operational safety. (2) The rigid introduction platform can shorten the elongation of the imported platform by means of integral flipping and disassembly combination, which can effectively expand the working range of the tower crane and improve the applicable safety of the tower crane. At the same time, the external introduction platform is detachable, and the internal introduction platform can work alone, and has strong applicability to different arm length conditions.
