Description
技术领域technical field
本发明属于起重机维修技术领域，具体涉及一种起重机专用行车。The invention belongs to the technical field of crane maintenance, and in particular relates to a crane special crane.
背景技术Background technique
起重设备有的工作特点是做间歇性运动，即在一个工作循环中取料、运移、卸载等动作的相应机构是交替工作的，起重机在市场上的发展和使用越来越广泛。常见的起重机主要由横梁、大车运行机构、小车运行机构、起升机构和电气设备等部件组成，其中横梁对整个起重机的工作效率和安全运行起着至关重要的作用。为保障起重机的安全运行，经常需要对起重机的横梁进行维修、保养。为保证起重机的承重能力，横梁的材质多为金属合金。而在维修横梁的过程中，经常需要搬运横梁。Some working characteristics of lifting equipment are intermittent movements, that is, in a working cycle, the corresponding mechanisms for retrieving, moving, unloading and other actions work alternately. The development and use of cranes in the market are becoming more and more extensive. Common cranes are mainly composed of beams, cart running mechanism, trolley running mechanism, lifting mechanism and electrical equipment, among which the beam plays a vital role in the working efficiency and safe operation of the whole crane. In order to ensure the safe operation of the crane, it is often necessary to repair and maintain the beam of the crane. In order to ensure the load-bearing capacity of the crane, the material of the beam is mostly metal alloy. In the process of repairing the beam, it is often necessary to carry the beam.
目前的一些搬运横梁的方法是采用行车，搬运时，用行车的挂钩钩住横梁中部，然后进行搬运。这种行车结构存在一定的缺陷：需要寻找横梁的中心点，然后再用挂钩钩住，如果没有找准横梁的中心点，在搬运横梁的过程中，容易出现横梁失衡而倾斜的情况，而如果发生失衡的话，就很容易出现横梁从挂钩滑落进而砸到地面的情况，导致人员伤亡，存在非常大的安全隐患。Some current methods of carrying the crossbeam are to adopt driving, and during carrying, hook the crossbeam middle part with the hook of driving, then carry. There are certain defects in this kind of driving structure: it is necessary to find the center point of the beam, and then hook it with a hook. If the center point of the beam is not found, it is easy to cause the beam to be out of balance and tilt during the process of transporting the beam. If there is an imbalance, it is easy for the beam to slip from the hook and hit the ground, resulting in casualties and a very large safety hazard.

搬运横梁8时，将横梁8放置在支撑板20上，启动液压缸2，支撑板20带着横梁8向上移动。当横梁8向上移动至挤压转动板4时，转动板4向上转动，横梁8继续向上移动；转动板4向上转动时，连杆5向上摆动，主动齿条50沿着方形架10向上滑动。如图4所示，主动齿条50向上滑动带动齿轮51转动，从动齿条52向下滑动。如图5所示，当从动齿条52向下时，两个转动杆6分别向外摆动，支撑臂60也向外摆动，夹持部逐渐打开。当支撑板20带着横梁8向上移动至进入夹持部时，吸盘70吸住横梁8，转动板4失去横梁8向上的支撑力，开始在自身重力作用下向下转动，即图4的状态，转动板4向下转动带动连杆5向下摆动，主动齿条50向下滑动，齿轮51反向转动，从动齿条52向上滑动，转动杆6、支撑臂60向内收拢，夹持部重新关闭。再让液压缸2带着支撑板20向下移动至转动板4下方，即可推着移动架1搬运至指定位置。可见，本方案不用如现有技术一样用挂钩式的行车去寻找横梁8的中心点，而只需要通过两端的吸盘70即可简单地固定住横梁8的两端，横梁8平衡性更好。而且在搬运过程中，吸盘70首先会对横梁8起主要的固定作用，闭合的夹持部在横梁8的底部还会起辅助支撑作用，而即使横梁8因意外因素从吸盘70、夹持部脱落，也还能落入位于底部的转动板4上；实现三重保护，有效防止横梁8脱落至地面造成的人员伤亡等意外事故。When carrying the crossbeam 8, the crossbeam 8 is placed on the support plate 20, the hydraulic cylinder 2 is activated, and the support plate 20 moves upward with the crossbeam 8. When the crossbeam 8 moved upwards to extrude the rotating plate 4, the rotating plate 4 turned upwards, and the crossbeam 8 continued to move upwards; As shown in FIG. 4 , the driving rack 50 slides upward to drive the gear 51 to rotate, and the driven rack 52 slides downward. As shown in FIG. 5 , when the driven rack 52 moves downward, the two rotating rods 6 swing outward respectively, and the support arm 60 also swings outward, and the clamping portion is gradually opened. When the support plate 20 moves upward with the beam 8 to enter the clamping part, the suction cup 70 sucks the beam 8, and the rotating plate 4 loses the upward supporting force of the beam 8, and starts to rotate downward under its own gravity, that is, the state of FIG. 4 , the rotating plate 4 rotates downward to drive the connecting rod 5 to swing downward, the driving rack 50 slides downward, the gear 51 reversely rotates, the driven rack 52 slides upward, the rotating rod 6 and the support arm 60 draw inward, clamping Department closed again. Then let the hydraulic cylinder 2 move down with the support plate 20 to the bottom of the rotating plate 4, and then push the mobile frame 1 to be transported to a designated position. It can be seen that this solution does not need to use a hook-type crane to find the center point of the beam 8 as in the prior art, but only needs to use the suction cups 70 at both ends to simply fix the two ends of the beam 8, and the balance of the beam 8 is better. And in the handling process, the suction cup 70 will at first play a major role in fixing the crossbeam 8, and the closed clamping part will also play an auxiliary supporting role at the bottom of the crossbeam 8, and even if the crossbeam 8 is removed from the suction cup 70, the clamping part due to accidental factors Fall off, also can fall on the rotating plate 4 that is positioned at the bottom; Realize triple protection, effectively prevent accidents such as casualties that beam 8 falls off to the ground and cause.
