Problems solved by technology

[0005] When the cylinder diameter of the column exceeds φ400mm, especially when the cylinder diameter reaches 500mm, it is very difficult to disassemble the guide sleeve, especially the first few buckles that are loosened at the beginning cannot be disassembled only by the power of the motor

specific Embodiment approach

[0015] The preferred specific implementation of the large-bore column cylinder dismantling machine of the present invention is:

[0016] It includes a bed, a power bed head, and a tailstock. The power bed head is connected with a driving device through a ratchet assembly, and the ratchet assembly is provided with an afterburner jack.

[0017] A clamping oil cylinder and a manual clamping device are arranged on the tailstock.

[0018] A plurality of fixing seats are arranged on the bed body, and a tailstock jack is arranged between the tailstock and the fixing seat.

[0019] One or more brackets are arranged on the bed.

[0020] The bracket includes a frame body, a V-shaped iron is arranged on the frame body, a screw is arranged between the frame body and the V-shaped iron, and a handle is arranged at the rear end of the screw.

[0021] The driving device includes a hydraulic motor or an electric motor.

[0022] The cylinder diameter of the large cylinder diameter column is greater than or...

specific Embodiment

[0026] Such as figure 1 , figure 2 As shown, the upright column 12 to be removed is fixed by the power head 3 and the tailstock 5, and the bracket 4 supports the upright column 12 to be removed. Among them, the tailstock 5 is fixed to the cylinder of the column 12 to be dismantled, a disassembly wrench matched with the column 12 to be dismantled is fixed on the power bed 3, and the disassembly wrench is fixed to the guide sleeve of the column 12 to be dismantled.

[0027] When disassembling, the afterburner jack 6 drives the ratchet assembly 2 and then drives the power bed head 3 to rotate. The power bed head 3 drives the disassembly wrench to rotate to loosen the guide sleeve; then the hydraulic motor 1 provides power to complete the subsequent disassembly work.

[0028] The function of the tailstock 5 to clamp the column is jointly completed by the clamping cylinder 9 and the manual clamping device 10. The manual clamping device 10 is mainly used for fine adjustment to ensure cen...

Abstract

The invention discloses a large-cylinder diameter upright post cylinder-removing machine, which comprises a bed body, a power bed head and a tail base, wherein the power bed head is connected with a driving device through a ratchet component; and the ratchet component is provided with a stressing jack. When an upright post guide sleeve is difficultly detached, the stressing jack can be used for unscrewing primarily, so the problem that the primary power is not enough is solved, a hydraulic motor is used for providing power to finish the subsequent work, a traditional upright post guide sleeve is detached, the working efficiency can be also improved, and an upright post of which the cylinder diameter is up to phi 500mm can be detached.

Description

Technical field [0001] The invention relates to a device for disassembling and assembling a column of a hydraulic support for mining, in particular to a cylinder dismantling machine for a column with a large cylinder diameter. Background technique [0002] With the continuous increase of the hydraulic support frame type, the cylinder diameter of the column has also been continuously increased, and at the same time it has also caused the difficulty of removing the guide sleeve. [0003] In the prior art, the column cylinder dismantling machines all use hydraulic motors for dismantling work. [0004] The above-mentioned prior art has at least the following disadvantages: [0005] When the cylinder diameter of the column exceeds φ400mm, especially when the cylinder diameter reaches 500mm, it is very difficult to disassemble the guide sleeve, especially the initial loosening of the buckles cannot be removed only by the power of the motor. Summary of the invention [0006] The purpose of t...
