Description

Technical Field

[0001] This invention belongs to the field of tunnel support machinery and equipment, specifically relating to a single-cylinder stepping anchor bolt and cable lifting mechanism. Background Technology

[0002] Currently, coal mine roadway support in my country mainly adopts a combination of rock bolts and anchor cables. The support process involves drilling holes in the roof and sidewalls of the excavated roadway, injecting anchoring agent into the holes, and finally inserting the rock bolts or anchor cables for tightening. Pre-tensioning is applied to the roof or sidewalls to support the roadway. Traditional rock bolt and cable installation requires a high degree of manual labor, and the support face is the most densely populated area underground, with support personnel and those waiting for mining and excavation concentrated there. Support work is carried out immediately after roadway excavation, resulting in a harsh working environment, low efficiency, high manpower requirements, poor safety, and severe imbalance between mining and excavation. Summary of the Invention

[0003] This invention aims to solve the problems of traditional anchoring methods, such as high manual involvement in rod and cable feeding, low work efficiency, large manpower requirements, and poor safety.

[0004] The present invention provides the following technical solution: a single-cylinder step-type anchor bolt and anchor cable lifting mechanism, including a drill frame main frame, a lifting mechanism, a guiding and positioning mechanism and a clamping mechanism mounted on the drill frame main frame;

[0005] The lifting mechanism's moving end is connected to a clamping mechanism; the clamping mechanism includes a movable clamping claw and a fixed clamping claw; the movable clamping claw is an L-shaped component, one end of which is hinged to the lifting mechanism, and the other end of which extends from the L-shaped end face as a clamping block, which has a first open groove for accommodating anchor bolts and anchor cables; the fixed clamping claw is hinged to the right angle of the L-shape of the movable clamping claw, and has a second open groove for accommodating anchor bolts and anchor cables; the movable clamping claw swings around the hinge axis, and the first and second open grooves interlock to grip the anchor bolts and anchor cables;

[0006] The guiding and positioning mechanism is located on the anchor bolt and anchor cable lifting path and is used to intermittently fix the anchor bolt and anchor cable;

[0007] During the lifting process, the clamping mechanism clamps the anchor bolt and anchor cable; during the lowering process, the clamping mechanism releases the anchor bolt and anchor cable, and the guiding and positioning mechanism fixes the anchor bolt and anchor cable. This process is repeated to complete the step-by-step lifting and insertion of the anchor bolt and anchor cable into the hole.

[0008] Furthermore, the guiding and positioning mechanism includes a left guide fixing sleeve and a right guide fixing sleeve. The left guide fixing sleeve and the right guide fixing sleeve are located on both sides of the anchor bolt and anchor cable lifting path and are installed on their respective drive mechanisms. The drive mechanisms drive the left guide fixing sleeve and the right guide fixing sleeve to move towards each other to grip the anchor bolt and anchor cable.

[0009] Furthermore, the second open groove has a notch at its waist, and the clamping block of the movable clamping claw can be inserted into the notch to shorten the width between the first and second open grooves.

[0010] Furthermore, the driving mechanism for the left guide sleeve and the right guide sleeve is a hydraulic cylinder.

[0011] Furthermore, the lifting mechanism is a lifting cylinder. The cylinder barrel of the lifting cylinder is fixed to the main frame of the drill frame through a lifting cylinder fixing seat, and a fixing pin is connected between the bottom of the cylinder barrel and the main frame of the drill frame. The end of the cylinder rod of the lifting cylinder is connected to a movable clamping claw.

[0012] Furthermore, the surfaces of the first and second open grooves that contact the anchor bolts and anchor cables are engraved with anti-slip textures.

[0013] Furthermore, the anchor bolts and anchor cables entering the left and right guide fixing sleeves are cone-shaped.

[0014] Furthermore, it is mounted on a drilling rig for automatic insertion of anchor bolts and anchor cables into the hole.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] This invention provides a single-cylinder step-type anchor bolt and cable lifting mechanism, which offers a new implementation method for the rod and cable feeding step in the anchoring process. Through single-cylinder lifting and adaptive adjustment of the mechanical claw linkage structure, an automatic rod and cable feeding workflow is realized. Compared with manual rod and cable feeding operations, the success rate of anchor bolt and cable entering the hole is higher and the efficiency is faster. At the same time, due to its simple structural design, it is beneficial to improve the operational reliability of the automated anchor bolt drilling rig when mounted on the whole machine.

[0017] The present invention provides a single-cylinder step-type anchor bolt and anchor cable lifting mechanism, which uses the linkage mechanical structure principle to autonomously control the clamping of anchor bolts and anchor cables, replacing hydraulic and electrical components, greatly reducing production costs and improving reliability.

[0018] The present invention provides a single-cylinder step-type anchor bolt and anchor cable lifting mechanism, which is designed with a guiding and positioning mechanism to prevent the anchor bolt and anchor cable from deviating from the center of the borehole during the lifting process, thereby greatly improving the success rate and reliability of lifting the anchor bolt and anchor cable into the hole.

[0019] The present invention provides a single-cylinder step-type anchor bolt and anchor cable lifting mechanism, which can be equipped in the drilling frame of the anchor bolt drilling rig. The mechanism is simple and easy to install, has low manufacturing cost, high interchangeability, and can be used with different models of drilling frames. It improves the automation level of the drilling frame and enhances the working efficiency of the whole machine to a certain extent. Attached Figure Description

Detailed Implementation

[0026] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0027] like Figure 1 As shown: A single-cylinder step-type anchor bolt and anchor cable lifting mechanism includes a drill frame main frame 1, a lifting mechanism, a guiding and positioning mechanism 2 and a clamping mechanism mounted on the drill frame main frame 1.

[0028] like Figure 3 , Figure 4 , Figure 5 As shown: The lifting mechanism's moving end is connected to the clamping mechanism; the clamping mechanism includes a movable clamping claw 7 and a fixed clamping claw 8; the movable clamping claw 7 is an L-shaped component, one end of which is hinged to the lifting mechanism, and the other end of which extends from the L-shaped end face as a clamping block, the clamping block having a first open groove 7.3 for accommodating anchor bolts and anchor cables; the fixed clamping claw 8 is hinged to the right angle of the L-shape of the movable clamping claw 7, the fixed clamping claw 8 having a second open groove 8.2 for accommodating anchor bolts and anchor cables, the movable clamping claw 7 swings around the hinge axis so that the first open groove 7.3 and the second open groove 8.2 interlock and grip the anchor bolts and anchor cables.

[0029] When the L-shaped movable clamping jaw 7 is lifted by the lifting mechanism, it remains to the left (as shown in the attached image). Figure 5 Based on the swaying trend (for reference), the anchor bolt and anchor cable 9 can be clamped by cooperating with the fixed clamping claw 8 on the left side; the leftward swaying trend of the movable clamping claw 7 will also affect the anchor bolt and anchor cable 9, and the upper end of the anchor bolt and anchor cable 9 is limited by the guide positioning mechanism 2, so the anchor bolt and anchor cable 9 can be continuously and stably lifted. Of course, the working condition of the single hydraulic cylinder stepping anchor bolt and anchor cable lifting mechanism of the present invention is that the end of the anchor bolt and anchor cable 9 has been guided into the guide positioning mechanism 2. The present invention is used for subsequent continuous lifting of the anchor bolt and anchor cable 9.

[0030] Specifically, the movable clamping jaw 7 has a movable clamping jaw rotary pin hole 7.1 and a movable clamping jaw cylinder fixing hole 7.2, while the fixed clamping jaw 8 has a fixed clamping jaw rotary pin hole 8.1. The movable clamping jaw rotary pin hole 7.1 and the fixed clamping jaw rotary pin hole 8.1 are connected by a pin, ensuring that the movable clamping jaw 7 and the fixed clamping jaw 8 can rotate around the axis. The movable clamping jaw cylinder fixing hole 7.2 is connected to the ear plate at the end of the lifting cylinder rod 6 by a pin, ensuring that the movable clamping jaw 7 and the lifting cylinder rod 6 can rotate around the axis.

[0031] The second open groove 8.2 has a notch at its waist, into which the clamping block of the movable clamping claw 7 can be inserted to shorten the width between the first open groove 7.3 and the second open groove 8.2; so that the first open groove 7.3 and the second open groove 8.2 can fully grip the anchor bolt and anchor cable 9; and anti-slip textures are engraved on the surfaces of the first open groove 7.3 and the second open groove 8.2 that contact the anchor bolt and anchor cable to increase the friction when in contact with the anchor bolt and anchor cable 9.

[0032] The guide positioning mechanism 2 is located on the anchor bolt and anchor cable lifting path and is used to intermittently fix the anchor bolt and anchor cable.

[0033] During the lifting process, the clamping mechanism clamps the anchor bolt and anchor cable; during the lowering process, the clamping mechanism releases the anchor bolt and anchor cable, and the guide positioning mechanism 2 fixes the anchor bolt and anchor cable. This process is repeated to complete the step-by-step lifting and insertion of the anchor bolt and anchor cable into the hole.

[0034] like Figure 2 As shown: The guide positioning mechanism 2 includes a left guide fixing sleeve 2.3 and a right guide fixing sleeve 2.4. The left guide fixing sleeve 2.3 and the right guide fixing sleeve 2.4 are located on both sides of the anchor bolt and anchor cable lifting path and are installed on their respective drive mechanisms. The drive mechanisms drive the left guide fixing sleeve 2.3 and the right guide fixing sleeve 2.4 to move towards each other to grip the anchor bolt and anchor cable.

[0035] Specifically, the driving mechanism for the left guide fixing sleeve 2.3 and the right guide fixing sleeve 2.4 is a hydraulic cylinder; the left hydraulic cylinder barrel 2.1 and the right hydraulic cylinder barrel 2.6 are fixed on the main frame 1 of the drill frame, and the left guide fixing sleeve 2.3 and the right guide fixing sleeve 2.4 are respectively connected to the ends of the left hydraulic cylinder piston rod 2.2 and the right hydraulic cylinder piston rod 2.5. During the upward movement of the anchor bolt and anchor cable 9, the left guide fixing sleeve 2.3 and the right guide fixing sleeve 2.4 do not fully contact the anchor bolt and anchor cable 9. The left guide fixing sleeve 2.3 and the right guide fixing sleeve 2.4 serve as guides. When the lifting mechanism finishes its one-time feed and resets, the left guide fixing sleeve 2.3 and the right guide fixing sleeve 2.4 tighten the anchor bolt and anchor cable 9 to prevent the anchor bolt and anchor cable 9 from sliding down.

[0036] The anchor bolt and anchor cable entry sides of the left guide fixing sleeve 2.3 and the right guide fixing sleeve 2.4 are cone-shaped, with a large inlet and a gradually narrowing structure that facilitates the introduction of the anchor bolt and anchor cable 9 between the left guide fixing sleeve 2.3 and the right guide fixing sleeve 2.4.

[0037] The lifting mechanism is a lifting cylinder. The cylinder barrel of the lifting cylinder is fixed to the main frame 1 of the drill frame through the lifting cylinder fixing seat 5, and the bottom of the cylinder barrel is connected to the main frame 1 of the drill frame by a fixing pin 3. The end of the cylinder rod of the lifting cylinder is connected to a movable clamping claw 7.

[0038] This single-cylinder stepping anchor bolt and cable lifting mechanism is mounted on a drilling rig for automatic insertion of anchor bolts and cables into the hole.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
