Description
Technical Field
The invention belongs to the technical field of production matching tools of switch cabinets, and particularly relates to a main rope and branch rope quick connecting device for hoisting of a switch cabinet.
Background
The switch cabinet of the electrical system is internally provided with a plurality of metal parts, and the whole switch cabinet is quite heavy. In the production debugging process, the maintenance process and the installation process of transferring each switch cabinet from a manufacturer to a user, the whole switch cabinet needs to be lifted for a plurality of times, and the lifting process is called lifting. In order to keep the switch cabinet in a horizontal posture in the hoisting process, four branch ropes with equal length are needed to be respectively tied at four corners of the switch cabinet, the upper ends of the four branch ropes are also needed to be connected with the lower end of a main rope at the same time, and the switch cabinet can be hoisted through the four branch ropes by pulling the main rope in the hoisting process.
In order to connect the four branch ropes with the main rope, the conventional measure adopted in the prior art is to tie the four branch ropes together into a bundle by using a clamp, and then connect the bundle of branch ropes with the main rope. However, the prior art has the following problems:
1. in each lifting process, the clamp is locked by bolts, and in order to ensure locking, a plurality of clamps or more bolts are usually required to be arranged for locking, so that the connection process is troublesome and time-consuming, and particularly time is wasted in emergency repair of the power system.
2. It is necessary to check repeatedly each time whether all clips are locked; in case that the clamp is not locked completely, a large potential safety hazard can be caused.
In order to solve the problems, the applicant designs a quick connection device for hoisting a main branch rope of a switch cabinet, and applies for a patent to the national intellectual property office, and the application number is 202221485420.X. However, the applicant has found in practice that the structure 202221485420.X still has the following drawbacks: the part of the first sliding block bearing vertical pressure is the inner end of the sliding block, the inner end of the sliding block is triangular, the deformation resistance of the triangular part bearing vertical pressure is poorer, particularly, the vertex of the triangle is weaker, and once the deformation is serious, the releasing is possibly generated; the radial movement of the sliding block depends on the elastic force of the radial spring, but the section size of the sliding block is matched and matched with the inner diameter of the guide sliding hole, so that friction force exists between the sliding block and the wall of the guide sliding hole, the sliding block can slide radially and be blocked, the blocking is generated inside the guide sliding hole, the outside is difficult to observe accurately, once the blocking happens, the sliding block cannot move to the radial inner side, the inner end part of the sliding block cannot block a rod cap at the upper part of the vertical inserted rod practically, namely the rod cap (vertical inserted rod) can be separated from a vertical blind hole of the first connecting piece, and potential safety hazards are formed.
