Description

Technical Field

[0001] The present invention relates to the technical field of electric lifting equipment, and in particular to a buffer base and an electric aerial work lifting device. Background Art

[0002] In the construction, operation and maintenance of power lines and substations, workers are often required to rise to a certain height to perform related operations. In the traditional process, most of them are carried out by manual climbing on foot. Not only is the work intensity of the workers high and the efficiency low, but the safety is relatively poor. In order to improve this problem, electric aerial work lifts have appeared in recent years, which can quickly raise the operator to a certain height and bring the operator back to the ground after the operator completes the work. During the frequent lifting and lowering actions of the lift, its bottom needs to collide and contact with the workbench frequently. Although a buffer pad is provided at the bottom of the lift, the existing buffer pad is of a single form and is prone to fall off after a short period of use. It is often impossible to carry out timely maintenance on site. In the case of a partial lack of buffer pads, the bottom of the lift will become uneven, and it will be unable to achieve synchronous contact with the workbench. In the long run, due to the structural design of the lift itself, the bottom of the lift will be deformed, posing a safety hazard. Summary of the invention

[0003] The purpose of the present invention is to avoid the deficiencies of the prior art and to provide a buffer base and an electric aerial work lifting device, thereby effectively solving the deficiencies in the prior art.

The fixed square tubes cooperate with the U-shaped structure to form a slot structure adapted to the buffer pad, and the buffer pad protrudes from the bottom of the fixed square tube, and the fixed square tube, the U-shaped structure and the connecting part are fixedly connected by a first bolt assembly.

[0005] Furthermore, the U-shaped structure is provided with a perforation on the matching connection portion.

[0006] Furthermore, the perforations are square holes.

[0007] Furthermore, at least one buffer pad is provided at each end of the mounting plate.

[0008] Furthermore, the top of the fixed square tube is fitted with the bottom of the mounting plate, and the inner side of the fixed square tube is fitted with the U-shaped structure.

[0009] Furthermore, both sides of the mounting plate extend to the outside of the fixed square tube, and mounting holes are provided on the outside of the mounting plate.

[0010] Furthermore, the U-shaped structure extends through one end of the mounting plate to the other end, and a supporting structure is provided in the middle of the length direction of the U-shaped structure.

[0011] Furthermore, the support structure includes a support sleeve arranged on the inner side of the U-shaped structure, and the fixed square tube, the U-shaped structure and the support sleeve are fixedly connected by a second bolt assembly.

[0012] Furthermore, the fixed square tube is provided with a first disassembly hole and a second disassembly hole respectively cooperating with the first bolt assembly and the second bolt assembly.
