specific Embodiment approach

[0015] The large-bore column dismantling machine of the present invention, its preferred embodiment 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] The tailstock is provided with a clamping oil cylinder and a manual clamping device.

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

[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 lead screw is arranged between the frame body and the V-shaped iron, and a handle is arranged at the rear end of the lead screw.

[0021] The drive means includes a hydraulic motor or an electric motor.

[0022] The bore of the large bore column is greater than or equal to 400mm.

[0023] The bo...

specific Embodiment

[0026] Such as figure 1 , figure 2 As shown, the column 12 to be dismantled is fixed by the power bed head 3 and the tailstock 5, and the column 12 to be dismantled is supported by the bracket 4. Wherein, tailstock 5 is fixed with the cylinder body of column 12 to be dismantled, and the head of a bed 3 is fixed with the dismantling wrench supporting with column 12 to be dismantled, and dismounting wrench is fixed with the guide sleeve of column 12 to be dismantled.

[0027] During disassembly, first the ratchet assembly 2 is driven by the afterburner jack 6 to drive the power bed head 3 to rotate, and the power head head 3 rotates by driving the disassembly wrench to unscrew the guide sleeve; then the hydraulic motor 1 provides power to complete the follow-up disassembly work.

[0028] The function of clamping the column of the tailstock 5 is jointly completed by the clamping cylinder 9 and the manual clamping device 10, wherein the manual clamping device 10 is mainly used f...

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 dismantling device for a column of a mine hydraulic support, in particular to a cylinder dismantling machine for a column with a large cylinder diameter. Background technique [0002] With the continuous increase of the frame type of the hydraulic support, the cylinder diameter of the column is also continuously increased, which also causes the difficulty of dismounting the guide sleeve. [0003] In the prior art, the column dismantling machines all use hydraulic motors to carry out the dismantling work. [0004] There are at least the following disadvantages in the above-mentioned prior art: [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 few buttons that are loosened at the beginning cannot be removed only by the power of the motor. Contents of the invention [0006] The purpose of ...
