Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a wire rope clamping device for a drilling crane. Background Art

[0002] Well drilling is a process of drilling cylindrical holes of a certain depth into the ground using mechanical equipment at a pre-selected location. When the drilling equipment is working, it needs to be hoisted and moved to the destination first.

[0003] After searching, the Chinese patent publication number is CN112158750A, which discloses a wire rope clamping device for a drilling crane. This patent is to pull out the pin to disengage the second pin hole, so that the control component drives the auxiliary clamp block to move toward the control component, so that the arc-shaped brake pad clamps the tension rope. There are certain problems with this device: the bottom of the tension rope is connected to a heavy drilling component. After adjusting the length of the tension rope, directly pulling out the pin to release the tension rope will cause the drilling component to fall suddenly. Clamping the tension rope while it is moving will cause the brake pad to wear, and there are certain safety hazards. Utility Model Content

[0007] Pulling out the plug plate causes the control spring to push the limit plate to move, causing the convex nail to clamp the rope, thereby driving the wedge-shaped movable block to move, and the wedge-shaped movable block squeezes and drives the clamping mechanism to move.

[0008] Preferably, a plurality of rollers are rotatably connected to the inclined surface of the wedge-shaped movable block, and the inserting plate is slidably connected to the fixed plate.

On one side of each other, the sliding block 501 is connected to the connecting plate 502 by screws, and a plurality of control springs 503 are welded on the side of the connecting plate 502 close to each other, and a limit plate 504 is welded on the side of the control springs 503 close to each other, and a plurality of protruding nails 505 are fixedly connected to the limit plate 504. The bottom of the plug plate 402 is separated from the limit plate 504, so that the control spring 503 recovers its deformation and pushes the limit plate 504 to move, so that the limit plates 504 move in the direction close to each other, so that the protruding nails 505 contact and squeeze the lifting rope, thereby fixing the wedge-shaped movable block 401 on the lifting rope, so that the wedge-shaped movable block 401 moves into the clamping frame 102 along with the lifting rope, and then the clamping plate 302 squeezes the sliding block 501, pushing the connecting plate 502 to slide in the wedge-shaped movable block 401, so that the limit plate 504 further clamps the lifting rope;

[0026] Pulling out the inserting plate 402 causes the control spring 503 to push the limiting plate 504 to move, causing the protruding nail 505 to clamp the rope, thereby driving the wedge-shaped movable block 401 to move, and the wedge-shaped movable block 401 squeezes and drives the clamping mechanism to move.

[0027] A plurality of rollers 403 are rotatably connected to the inclined surface of the wedge-shaped movable block 401 , and the inserting plate 402 is slidably connected to the fixed plate 103 .

[0028] The clamping mechanism includes symmetrical clamping springs 301 , which are fixedly connected in the clamping frame 102 , and a clamping plate 302 is fixedly connected to one side of the clamping springs 301 close to each other.

[0029] The adjusting mechanism includes a movable rod 201, which is rotatably connected to the auxiliary block. The front end of the movable rod 201 is connected to a turntable 202 through a key. A pulley 203 is fixedly connected to the movable rod 201. A limiting hole is opened at the rear end of the pulley 203. The front end of the turntable 202 is connected to a rotation counter through a screw. The movable rod 201 is rotated by rotating the turntable 202, and the movable rod 201 drives the pulley 203 to rotate. The length of the suspension rope is adjusted according to the rotation counter. After the position is determined, the plug plate 402 is pulled upward.

[0030] A plurality of sliding grooves are provided on one side of the wedge-shaped movable block 401 close to each other, and a connecting component 6 is provided in the sliding groove. The connecting component 6 includes symmetrical connecting springs, which are fixed in the wedge-shaped movable block 401. A connecting rod is fixed on one end of the connecting spring close to each other. As the suspension rope moves, the wedge-shaped movable block 401 makes the roller 403 contact and roll with the inclined surface of the clamping plate 302, so that the wedge-shaped movable block 401 gradually squeezes the clamping plate 302 to deform the clamping spring 301, and a certain thrust is applied to the wedge-shaped movable block 401 to compress the connecting spring, and the connecting rod slides in the wedge-shaped movable block 401, so that the symmetrical wedge-shaped movable blocks 401 move toward each other.

[0031] The bottom of the base plate 101 is rotatably connected to multiple ground anchors 702, and the top of the base plate 101 is connected to a symmetrical motor 701 by bolts. The output shaft of the motor 701 is connected to the top of the ground anchor 702 on one side through a coupling. The output shaft of the motor 701 is connected to a connecting belt 8, and the connecting belt 8 is connected to the top of the ground anchor 702 on the other side. When the motor 701 rotates, it drives the multiple ground anchors 702 to rotate through the connecting belt 8, so that the ground anchor 702 is drilled into the ground and the device is fixed to the ground.

[0032] Working principle: When in use, the motor 701 rotates, and drives multiple ground anchors 702 to rotate through the connecting belt 8, so that the ground anchors 702 are drilled into the ground, and the device is fixed on the ground. The lifting rope is passed through the limiting holes on the pulley 203 and fixed, and then the lifting rope is passed through between the symmetrical wedge-shaped movable blocks 401, and finally passed through the through hole of the clamping frame 102. The guide wheel 9 guides the lifting rope, and then the movable rod 201 is rotated by rotating the turntable 202. The movable rod 201 drives the pulley 203 to rotate, and the lifting rope length is adjusted according to the rotation counter. After determining the position, the plug plate 402 is pulled upward to make the bottom of the plug plate 402 disengage from the limiting plate 504, so that the control spring 503 recovers its deformation and pushes the limiting plate 504 to move, so that the limiting plates 504 are close to each other. The wedge movable block 401 moves in the same direction as the lifting rope, so that the protruding nail 505 contacts and squeezes the lifting rope, thereby fixing the wedge movable block 401 on the lifting rope, so that the wedge movable block 401 moves into the clamping frame 102 along with the lifting rope, and the wedge movable block 401 contacts the roller 403 as the lifting rope moves and rolls with the inclined surface of the clamping plate 302, so that the wedge movable block 401 gradually squeezes the clamping plate 302 to deform the clamping spring 301, and applies a certain thrust to the wedge movable block 401 to compress the connecting spring, and the connecting rod slides in the wedge movable block 401, so that the symmetrical wedge movable blocks 401 move toward each other, and then the clamping plate 302 squeezes the sliding block 501, pushing the connecting plate 502 to slide in the wedge movable block 401, so that the limit plate 504 further clamps the lifting rope.
