Description

TECHNICAL FIELD

[0001] The utility model relates to a disassembly-free door plate device convenient to maintain belongs to engineering machinery's technical field. BACKGROUND

[0002] In the design of the aerial work platform with the jib, the counterweight system plays a vital role. The counterweight can not only ensure the stability of the equipment during lifting and telescoping operations, but also effectively prevent overturning and accidents caused by improper operation or external interference. In order to ensure the effectiveness and safety of the counterweight, manufacturers usually combine the counterweight with the electrical control box, connector, hydraulic valve, tool box and other equipment components during design. These components are generally installed in the counterweight or beside the counterweight, so as to facilitate use and debugging during work.

[0003] However, due to the working nature of these components and the need for maintenance, how to ensure the performance of the platform while providing sufficient maintenance convenience has become an urgent problem to be solved. In the current design, the common practice is to set a maintenance opening for the counterweight system, so that maintenance personnel can conveniently debug and maintain the electrical control box, hydraulic valve, connector and other components. In order to facilitate the operation of maintenance personnel, a door plate is usually directly fixed to the opening of the counterweight by using bolts. Although this design can achieve a certain convenience, it exposes some obvious problems in actual application and maintenance process.

[0004] In some after-sales maintenance or factory debugging scenarios, maintenance personnel need to frequently disassemble and reinstall these door plates in order to perform debugging, inspection or maintenance operations. Although this design provides the opening and convenience of disassembly for the workers, it also brings a lot of inconvenience and trouble. The main problem is that disassembling these door plates usually requires the removal of multiple bolts, and the positions of these bolts are often difficult to operate, especially in the maintenance environment of some aerial work platforms, which is very inconvenient to operate.

[0005] In addition, the process of removing the door plate not only consumes time and effort, but also requires higher operation skills of personnel. In the busy construction site environment, workers usually need to quickly complete the task to reduce the impact on the progress of the work. However, the disassembly of the door plate often becomes complicated due to the number and position of the bolts, and additional tools are often needed to assist in the operation, which also leads to a significant reduction in the efficiency of maintenance. Especially in some more urgent maintenance or debugging tasks, this disassembly work will delay the work time and affect the construction progress.

[0006] After the removal of the counterweight door panel, the workers usually face a new problem - the storage location of the door panel. In some narrow construction sites, especially those more crowded construction sites, maintenance personnel often have difficulty finding a suitable place to place the door panel that has been removed. Because the door panel is large, and is usually made of metal material, and is heavy, casual placement can cause scratches on the equipment or damage to other facilities.

[0007] The most common situation is that due to the lack of a suitable storage location, the door panel is often randomly stacked or placed in a corner of the work site, which not only causes scratches on the paint and surface coating, affecting the appearance of the equipment, but also causes damage to the door panel itself, affecting subsequent use and disassembly. Although the damage seems small, in the long run, it will affect the appearance and value of the platform, and even affect the service life and maintenance quality of the platform. SUMMARY

[0008] The purpose of the application is to solve the above technical problems.
