Description

Technical Field

[0001] This utility model relates to the field of boom disassembly technology, and in particular to a device for quickly fixing booms for disassembly operations. Background Technology

[0002] The base of the boom assembly has a spring installed. During the disassembly process, you need to press down on the boom base to retract the spring and expose the shaft on the boom base for disassembly.

[0003] Because of the large number of internal components and relatively complex structure, articulated boom assemblies are prone to damage during production. Regular maintenance is required, including disassembling the assembly and replacing internal components to reduce the failure rate during production.

[0004] However, during the disassembly process, due to the high elasticity of the spring, it is difficult for one operator to carry out the work. It is necessary to use other tools or two operators to assist in the work. However, there is currently a lack of corresponding targeted equipment, which makes the disassembly of the curved arm base time-consuming and laborious. In addition, the spring is in a compressed state during the disassembly process, which poses a certain risk.

[0005] Therefore, it is necessary to provide a device for quickly fixing the boom for disassembly operations to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a device for quickly fixing and disassembling a bent arm, which solves the problem that the disassembly process is not only time-consuming and laborious due to the large spring force, but also increases the risk during the disassembly process because the spring is in a compressed state.

[0007] To solve the above-mentioned technical problems, the device for quickly fixing and disassembling the curved arm provided by this utility model includes: a movable base frame;

The piston, connected to the L-shaped lifting rods on both sides, presses against the boom base via the extended ends of the lifting rods, achieving rapid boom fixation. The positioning seat is located at the front of the work platform; its U-shaped structure facilitates boom placement. A stop rod behind the positioning seat effectively prevents boom rotation caused by excessive force during disassembly due to corrosion of the nut on the boom's central shaft.

[0011] Preferably, two sets of placement frames are installed on the top of the top frame, and a control box with a door is installed on the front of the disassembly frame;

[0012] The control box contains power switches and controllers for operating the equipment.

[0013] Preferably, a mounting bracket is installed on the top of the top frame, and a monitoring component is installed on the bottom of the mounting bracket near the other end;

[0014] The monitoring component is a camera device that can monitor the disassembly process.

[0015] Preferably, the movable base includes a movable plate and casters, the casters being installed on the bottom of the movable plate near the four corners; the lifting assembly includes a fixed base, a telescopic component, and a docking base, the fixed base being used to install the telescopic component on the bottom of the top frame.

[0032] Positioning seat 15, the positioning seat 15 is installed on the top of the top frame 9, the top of the positioning seat 15 is equipped with a stop rod 16 at the back position, and the top of the top frame 9 is equipped with a curved arm 17 with a curved arm base 19.

[0033] The lifting rod 14 moves within the movable opening 18. The work platform is controlled by a foot switch below. The air circuit connects to the cylinder, driving the cylinder piston to move. The piston is connected to the L-shaped lifting rods on both sides, and the extended end of the lifting rods presses against the bent arm base, achieving rapid fixation of the bent arm. The positioning seat is located at the front of the work platform. The U-shaped structure facilitates the placement of the bent arm.

After the work is completed, the foot switch controls the cylinder piston to retract, and the bent arm assembly can be removed before proceeding to the disassembly of the next bent arm. The operation process is simple and efficient. The foot switch 2 can control the operation of the lifting assembly 7.

[0034] The top of the top frame 9 is equipped with two sets of placement frames 10, and the front of the disassembly frame 3 is equipped with a control box 5 with a door 4.

[0035] The control box 5 contains a power switch and a controller for controlling the operation of the equipment, and the box door 4 is equipped with a lock.

[0036] A mounting bracket 11 is installed on the top of the top frame 9, and a monitoring component 12 is installed on the bottom of the mounting bracket 11 near the other end.

Lifting rods 14, passing through movable openings 18, are installed on the top of the movable plate 6 near both sides. A limiting plate 13, capable of locking the boom base 19, is installed at the top of each lifting rod 14. A positioning seat 15 with a stop rod 16 is installed on the top of the top frame 9. The stop rod 16 connects to the boom base 19 to prevent the boom 17 from rotating during operation. In actual use, the lifting assembly 7 moves the lifting rods 14 up and down, assisting in limiting their movement. Plate 13 quickly fixes the curved arm base 19. The positioning part adopts a U-shaped positioning seat 15, which fits the circular part below the curved arm 17, so as to achieve quick positioning.
