AI Technical Summary

Technical Problem

When using the oil pump, the staff needs to climb high and enter the support frame. The high-level design of the device increases the operator's exit threshold. At the same time, the storage and fixing of the device is difficult, requiring a lot of effort and not easy to fix.

Method used

An adjustable oil pump support arm for easy maintenance is designed, and the scissor-type connecting rod is pushed up and lifted up the support through the cylinder, which facilitates staff to rise and repair; at the same time, structural designs such as fall-off plates, movable doors and placement plates achieve convenient up and down movement of operators and placement and storage of tools.

Benefits of technology

It greatly facilitates the use of operators, reduces the difficulty of entering and leaving the device, and improves the convenience of tool storage and fixing through structures such as cylinders and magnetic plates.

Abstract

An adjusting mechanism comprises a lower support, one side of the inner wall of the lower support is rotatably connected with an air cylinder, the top of the lower support is rotatably connected with a shear fork type connecting rod, the piston end of the air cylinder is movably connected with the middle of the bottom of the shear fork type connecting rod, and the piston end of the air cylinder is movably connected with the middle of the bottom of the shear fork type connecting rod. The top end of the lower support is movably connected with a shear fork type connecting rod, the top end of the shear fork type connecting rod is movably connected with an upper support, limiting frames are symmetrically and fixedly connected to the top of the lower support and the bottom of the upper support, an anti-falling plate is fixedly installed on the top of the upper support, connecting frames are symmetrically and fixedly connected to one side of the outer wall of the upper support, and movable doors are slidably connected to the inner walls of the connecting frames. The anti-falling plate is arranged at the top of the upper support to prevent an operator from falling due to unstable gravity center when standing on the upper support, the movable door is mounted on one side of the anti-falling plate, the movable door is turned over to be opened and the ladder stand is opened, the operator can conveniently enter the top of the device with the help of the ladder, and use of the operator is greatly facilitated.
