Description

Technical Field

[0001] The utility model relates to the technical field of drilling rig clamping equipment, in particular to a mining full hydraulic tunnel drilling rig clamp with a protection structure. Background Art

[0002] A drilling rig is composed of machines, units and mechanisms. A drilling rig is a mechanical device that drives the drill tool underground to obtain physical geological data during exploration or mineral resource development. During the use of the drilling rig, the drill rod needs to be fixed by a clamp to keep the drilling rig stable during operation.

[0003] For example, the utility model: "A fully hydraulic tunnel drill clamp with anti-falling function for mining", with the announcement number: "CN212535562U", realizes the power source of the entire fixing mechanism by rotating the rotating handle manually. Since the force can be transmitted, the threaded through hole is used in conjunction with the threaded rod while rotating the rotating handle, so that further positioning can be achieved. Finally, by setting the positioning groove, the positioning of the slip can be achieved, so that the anti-falling effect is better. However, during the implementation of this patent, the drill rod is directly fixed by the slip. During the rotation of the drill rod, sliding friction is generated between the slip and the drill rod, which easily causes wear of the drill rod and the slip, and the protection effect on the drill rod is poor, and the service life of the device is greatly reduced.

[0024] Furthermore, second ball grooves 7 are evenly arranged on the inner side of the second clamping plate 5, and second balls 6 are installed inside the second ball grooves 7. After the drill rod is clamped and fixed by the first clamping plate 2 and the second clamping plate 5, the drill rod contacts the first balls 3 and the second balls 6. When in use, the drill rod rotates, and the first balls 3 and the second balls 6 can rotate with the drill rod, which can convert sliding friction into rolling friction, reduce wear of the drill rod, and better protect the drill rod.

[0025] Furthermore, a first fixing spring 12 is installed at the bottom of the second L-shaped plate 9, and the end of the first fixing spring 12 away from the second L-shaped plate 9 is connected to the mounting sleeve 10. The elastic action of the first fixing spring 12 pulls the second L-shaped plate 9 to move, and the second L-shaped plate 9 drives the second clamping plate 5 to move through the first L-shaped plate 8, so that drill rods of different diameters can be clamped and fixed by the first clamping plate 2 and the second clamping plate 5.

[0026] Furthermore, a mounting hole 15 is provided at the top of the mounting sleeve 10 away from one end of the first clamping plate 2, and a fixing rod 14 is installed inside the mounting hole 15. The fixing rod 14 is inserted into the corresponding fixing hole 13 on the second L-shaped plate 9. The second L-shaped plate 9 is limited by the fixing rod 14, so that the second L-shaped plate 9 can be fixed to prevent the second clamping plate 5 from continuing to move during use, and the drill rod can be clamped firmly.

[0027] Furthermore, a connecting plate 16 is installed at the end of the fixed rod 14 away from the first clamping plate 2, and a second fixing spring 17 is installed at the bottom of the connecting plate 16 close to the mounting sleeve 10. The end of the second fixing spring 17 away from the connecting plate 16 is connected to the mounting sleeve 10.

[0028] Furthermore, a wear-resistant layer is provided on the outer side of the first ball 3 , which is beneficial to prolonging the service life of the first ball 3 .

[0029] Working principle:

[0030] When in use, first place the drilling rig on the top of the support plate 1, and place the drill rod on the inner side of the first clamping plate 2, and support the drill rod through the first clamping plate 2;

[0031] Then the staff can pull the connecting plate 16, the connecting plate 16 stretches the second fixing spring 17, and the connecting plate 16 drives the fixing rod 14 to move together, and the fixing rod 14 can be taken out from the fixing hole 13, so that the fixing rod 14 can release the restriction of the second L-shaped plate 9, so that the second L-shaped plate 9 can move;

[0032] At this time, the elastic action of the first fixing spring 12 causes it to pull the second L-shaped plate 9 to move, and the second L-shaped plate 9 drives the second clamping plate 5 to move through the first L-shaped plate 8, so that drill rods of different diameters can be clamped and fixed by the first clamping plate 2 and the second clamping plate 5;

[0033] The staff loosens the connecting plate 16. At this time, the elastic action of the second fixing spring 17 causes it to pull the connecting plate 16 to move and reset. The connecting plate 16 drives the fixing rod 14 to move together. The fixing rod 14 can be inserted into the corresponding fixing hole 13 on the second L-shaped plate 9. The second L-shaped plate 9 can be fixed by the fixing rod 14 to prevent the second clamping plate 5 from continuing to move during use, so that the drill rod can be firmly clamped.

[0034] During use, after the drill rod is clamped and fixed by the first clamping plate 2 and the second clamping plate 5, the drill rod contacts the first ball 3 and the second ball 6. When in use, the drill rod rotates, and the first ball 3 and the second ball 6 can rotate along with the drill rod, thereby converting sliding friction into rolling friction, reducing the wear of the drill rod and providing better protection for the drill rod.
