[0043] Related technical solution number twenty-five is a method of using a mining anchor cable retraction machine device based on a double telescopic cylinder. The steps are as follows: the mining anchor cable dismantling assembly pulls the steel strand; the machine body provides intermediate connection and support between the mining anchor cable dismantling assembly and the telescopic leg; the telescopic leg places the mining anchor cable dismantling assembly in an upper position, thereby driving the anchor cable retraction stroke downward.

[0044] The technical effect of the above technical solution is that it highlights the technical feature of driving the anchor cable retraction stroke downward, and introduces its application in the technical field of the use method of the mining anchor cable retraction machine device based on double telescopic cylinder.

[0045] The twenty-sixth related technical solution comprises the following steps: when the retractable body of the anchor release unit separates from the outer port of the moving cylinder and the outer end face of the anchor release unit separates from the outer end face of the segmented body unit, the spring part I is in an extended state, the segmented body unit is located in the outer port of the moving cylinder, at least three segmented body units are in a closed state, and at least three segmented body units clamp the steel strand; when the retractable body of the anchor release unit is placed in the outer port of the moving cylinder and the outer end face of the anchor release unit is in contact with the outer end face of the segmented body unit, the spring part I is in a compressed state, the segmented body unit moves inward in the outer port of the moving cylinder, at least three segmented body units are in an expanded state, and at least three segmented body units clamp the steel strand. When the wrench part rotates on the upper end face of the middle body of the handle part, it overcomes the elastic energy stored in the spring part II located on the control rod part I, causing the control rod part I to move laterally, controlling the working state of the first valve core in the valve part. When the control nut part located on the control rod part II rotates, the control nut part located on the control rod part II acts on the outer surface of the middle body of the handle part, overcoming the elastic energy stored in the spring part II located on the control rod part II, causing the control rod part II to move laterally, controlling the working state of the second valve core in the valve part. When the control nut part located on the control rod part III rotates, the control nut part located on the control rod part III... The action of the part on the outer surface of the middle body of the grip part overcomes the elastic energy storage of the spring part II located on the control rod part III, causing the control rod part III to move laterally. This controls the working state of the third valve core in the valve part, and through the valve part, controls the opening and closing state of the telescopic leg and the high-pressure air source. When the top sleeve part is connected to the high-pressure air source, the high-pressure gas enters the telescopic cylinder part, causing the inner piston cylinder in the telescopic cylinder part to extend on the middle piston cylinder in the telescopic cylinder part, causing the adjacent middle piston cylinders in the telescopic cylinder part to extend, and causing the middle piston cylinder in the telescopic cylinder part to extend on the outer piston cylinder in the telescopic cylinder part. When the inner side stepped surface of the intermediate piston cylinder of the telescopic cylinder is in a mating state with the outer side stepped surface of the inner piston cylinder of the telescopic cylinder, when adjacent intermediate piston cylinder steps of the telescopic cylinder are in a mating state, and when the outer piston cylinder step of the telescopic cylinder is in a mating state with the outer side stepped surface of the intermediate piston cylinder of the telescopic cylinder, the stop seat and the stop ring move with the intermediate piston cylinder and the inner piston cylinder of the telescopic cylinder, causing the upper end face of the stop seat to separate from the lower end face of the top sleeve, causing the telescopic leg to extend. When the top sleeve is disconnected from the high-pressure air source, under the weight of the machine body, the mining anchor cable disassembly assembly, the operating arm, and the support frame...The inner piston cylinder in the telescopic cylinder section retracts on the middle piston cylinder in the telescopic cylinder section; adjacent middle piston cylinders in the telescopic cylinder section retract; and the middle piston cylinder in the telescopic cylinder section retracts on the outer piston cylinder in the telescopic cylinder section. This causes the upper end face of the stop seat section to contact the lower end face of the top sleeve section, causing the telescopic leg to retract. When the power air source port of the high-pressure pump section is connected to the air source output port, the high-pressure pump section is in working condition. In the first state, the high-pressure pump section is connected to the oil tank section. The high-pressure pump section outputs high-pressure liquid, which is then delivered to the mining anchor cable dismantling assembly via the valve section, putting the mining anchor cable dismantling assembly into operation. When the valve section is closed, high-pressure liquid is no longer delivered to the mining anchor cable dismantling assembly. When it is necessary to unanchor the mining steel strand, the telescopic leg is extended. The angle is adjusted by the frame section on the upright beam section and the clamp strip I on the frame section, allowing the steel strand to pass through the clamping section, guide cable section, and anchor release device section. The segmented body, spring part I, spring seat part, and inner cylinder of the pulling telescopic cylinder part pass through the middle cylinder of the pulling telescopic cylinder part, causing the middle cylinder of the pulling telescopic cylinder part to extend outward from the outer cylinder and inner cylinder of the pulling telescopic cylinder part. This causes the support cylinder part to move inward, placing the support cylinder part onto the locking sleeve, thereby installing the mining anchor cable disassembly assembly onto the locking sleeve. When the outer cylinder and inner cylinder of the pulling telescopic cylinder part move outward on the middle cylinder of the pulling telescopic cylinder part, at least three segmented body parts clamp the steel strand, causing the steel strand to move outward. Pulling involves moving the outer cylinder and inner cylinder of the pulling telescopic cylinder section inward on the middle cylinder of the pulling telescopic cylinder section, pulling the steel strand outward into a bent state. At least three segmented sections separate the steel strand, which moves outward from the clamping section, guide section, anchor release section, segmented sections, spring section I, spring seat section, and inner cylinder of the pulling telescopic cylinder section, thus completing one round of anchor cable pulling outward. When the outer cylinder and inner cylinder of the pulling telescopic cylinder section move outward on the middle cylinder of the pulling telescopic cylinder section, the telescopic leg is retracted by the operating arm, moving downward toward the mine anchor cable disassembly assembly, thereby assisting in the outward pulling of the steel strand.

[0046] The technical effect of the above solution is that it enables the adjustment of the working position of the anchor cable during unanchoring.

[0047] The technical effects of this invention are as follows: pressure relief and safety assurance: release the constraints of the roof support, release the stress of the surrounding rock, reduce the roof pressure and impact risk of the working face, eliminate gas hazards: reduce the gas accumulation space caused by the suspended roof, which is conducive to gas extraction and discharge, resource recycling and cost reduction: recycle anchors, pallets and other materials to reduce the waste of support materials.

[0048] In this technical solution, the body, the mining anchor cable disassembly assembly, and the telescopic leg are the basic components and essential technical features of the invention. The operating arm, support frame, and power hydraulic assembly are functional components, features that achieve other technical effects of the invention.

When the retractable body of the anchor releaser 24 is placed in the outer port of the moving cylinder 23 and the outer end face of the anchor releaser 24 is in contact with the outer end face of the segmented body 27, the spring part I 29 is in a compressed state, causing the segmented body 27 to move inward in the outer port of the moving cylinder 23, with at least three segmented body 27 in an expanded state, separating the steel strand 10. When the wrench part 35 rotates on the upper end face of the intermediate body of the handle part 33, it overcomes the elastic energy stored in the spring part 2 39 located on the control rod part 1 34, causing the control rod part 1 34 to move laterally, thereby controlling the working state of the first valve core of the valve part 30. When the control nut part 38 located on the control rod part 2 36 rotates, the control nut part 38 on the control rod part 2 36 acts on the outer surface of the intermediate body of the handle part 33, overcoming the elastic energy stored in the spring part 2 39 located on the control rod part 2 36, causing the control rod part 2 36 to move laterally. The control lever 37 moves laterally to control the working state of the second valve core in the valve section 30. When the control nut 38 on the control lever 37 is rotated, the control nut 38 on the control lever 37 acts on the outer surface of the middle body of the grip lever 33, overcoming the elastic energy stored in the spring 29 on the control lever 37, causing the control lever 37 to move laterally and control the working state of the third valve core in the valve section 30. Through the valve section 30, the opening and closing state of the telescopic leg 4 and the high-pressure air source is controlled. When the top sleeve 46 is connected to the high-pressure gas source, the high-pressure gas enters the telescopic cylinder 41, causing the inner piston cylinder in the telescopic cylinder 41 to extend on the middle piston cylinder in the telescopic cylinder 41, causing adjacent middle piston cylinders in the telescopic cylinder 41 to extend between each other, and causing the middle piston cylinder in the telescopic cylinder 41 to extend on the outer piston cylinder in the telescopic cylinder 41. When the inner side step surface of the middle piston cylinder in the telescopic cylinder 41 is in a mating state with the outer side step surface of the inner piston cylinder in the telescopic cylinder 41, the adjacent middle piston cylinder step surfaces in the telescopic cylinder 41 are in a mating state, and the outer piston cylinder step surface in the telescopic cylinder 41 is in a mating state with the outer side step surface of the middle piston cylinder in the telescopic cylinder 41, the stop seat 47 and the stop ring 4... 8. As the intermediate piston cylinder and the inner piston cylinder of the telescopic cylinder 41 move, the upper end face of the stop 47 is separated from the lower end face of the top sleeve 46, causing the telescopic leg 4 to extend. When the top sleeve 46 is disconnected from the high-pressure air source, under the weight of the machine body 1, the mining anchor cable dismantling assembly 2, the operating arm 3, and the support frame 5, the inner piston cylinder of the telescopic cylinder 41 retracts on the intermediate piston cylinder of the telescopic cylinder 41, the adjacent intermediate piston cylinders of the telescopic cylinder 41 retract, and the intermediate piston cylinder of the telescopic cylinder 41 retracts on the outer piston cylinder of the telescopic cylinder 41, causing the upper end face of the stop 47 to contact the lower end face of the top sleeve 46, causing the telescopic leg 4 to retract. When the power air source port of the high-pressure pump unit 82 is connected to the air source output port, the high-pressure pump unit 82 is in working condition. The high-pressure pump unit 82 is connected to the oil tank unit 81, and outputs high-pressure liquid. Through the valve unit 83, the high-pressure liquid is delivered to the mining anchor cable dismantling assembly 2, putting the mining anchor cable dismantling assembly 2 in working condition. When the valve unit 83 is closed, high-pressure liquid is no longer delivered to the mining anchor cable dismantling assembly 2. When it is necessary to unanchor the mining steel strand 10, the telescopic leg 4 is extended. The angle of the frame part 51 on the upright beam part 55 and the clamp strip I 52 on the frame part 51 are adjusted. The steel strand 10 passes through the clamping part 25, the guide cable part 26, the anchor release part 24, the split body part 27, the spring part I 29, the spring seat part 28, and the inner cylinder of the pulling telescopic cylinder part 21. The middle cylinder of the pulling telescopic cylinder part 21 extends outward from the outer cylinder and the inner cylinder of the pulling telescopic cylinder part 21, causing the support cylinder shell part 22 to move inward. The support cylinder part 51 is placed on the locking sleeve 40, thereby installing the mining anchor cable disassembly assembly 2 on the locking sleeve 40. When the pulling telescopic cylinder part 2... The outer cylinder of section 1 and the inner cylinder of section 21 of the pulling telescopic cylinder move outward on the middle cylinder of section 21. At least three segmented sections 27 clamp the steel strand 10, causing the steel strand 10 to be pulled outward. When the outer cylinder and the inner cylinder of section 21 of the pulling telescopic cylinder move inward on the middle cylinder of section 21, the steel strand 10 is pulled outward in a bent state. At least three segmented sections 27 separate the steel strand 10. The steel strand 10 moves outward from the clamping section 25, the guide section 26, the anchor release section 24, the segmented sections 27, the spring section I 29, the spring seat section 28, and the inner cylinder of section 21, thereby completing one round of anchor cable pulling outward. When the outer cylinder and inner cylinder of the pulling telescopic cylinder section 21 move outward on the middle cylinder of the pulling telescopic cylinder section 21, the telescopic leg 4 is in a retracting motion by the operating arm 3, which moves the mining anchor cable disassembly assembly 2 downward, thereby assisting in pulling the steel strand 10 outward.

[0094] In verifying this invention, the inventors abandoned the existing technical features of using mining anchor steel strand 10 dismantling devices with pull-out telescopic cylinders, and first proposed a technical feature that extends the anchor cable retraction stroke downwards.

When the wrench part (35) rotates on the upper end face of the middle body of the handle part (33), it overcomes the elastic energy storage of the spring part II (39) located on the control rod part I (34), causing the control rod part I (34) to move laterally, controlling the working state of the first valve core of the valve part (30) in the valve part (30). When the control nut part (38) located on the control rod part II (36) rotates, the control nut part (39) located on the control rod part II (36) rotates. The control nut (38) on the 6) acts on the outer surface of the middle part of the grip (33), overcoming the elastic energy stored in the spring (39) on the control lever (36), causing the control lever (36) to move laterally, controlling the working state of the second valve core in the valve part (30). When the control nut (38) on the control lever (37) is rotated, the control nut (38) on the control lever (37) acts on the outer surface of the middle part of the grip (33), overcoming the elastic energy stored in the spring (39) on the control lever (37), causing the control lever (37) to move laterally. The lateral movement controls the working state of the third valve core in the valve section (30).

The high-pressure pump unit (82) is in working condition and is connected to the oil tank unit (81). The high-pressure pump unit (82) outputs high-pressure liquid, which is delivered to the mining anchor cable dismantling assembly (2) through the valve unit (83), so that the mining anchor cable dismantling assembly (2) is in working condition. When the valve unit (83) is in the closed state, the high-pressure liquid is no longer delivered to the mining anchor cable dismantling assembly (2). When it is necessary to unanchor the mining steel strand (10), the telescopic leg (4) is in an extension movement.
