Description

Technical Field

[0001] This utility model relates to the field of rock and soil anchoring technology in mining, and in particular to an anchor cable installation device. Background Technology

[0002] Anchor cables work by securing one end to a reliable bedrock or soil layer to resist external pressure or tension. They are also commonly used for support when encountering weak rock formations, fractured zones, or other adverse geological conditions during underground mining. For such challenging rock faces, a drilling hole is typically excavated before installing long anchor cables. The drilling process involves drilling from the bottom of the mine towards the surface. Due to the large diameter of the drilling hole and the considerable length of the anchor cables, installation is difficult, resulting in low efficiency with current methods. Utility Model Content

[0003] The purpose of this invention is to provide an anchor cable installation device that can solve the problem of difficult installation of long anchor cables in upward-moving holes.

[0004] The technical solution of this utility model is: an anchor cable installation device, including a base, an anchor cable, a guide seat mounted on the side surface of the base, and a transmission mechanism slidably connected to the side surface of the guide seat. The guide seat has an A end and a B end arranged opposite to each other. The transmission mechanism is provided with a first claw for clamping or releasing the anchor cable, and the B end of the guide seat is provided with a second claw for clamping or releasing the anchor cable. The end of the anchor cable extends from the second claw. When the transmission mechanism moves from the A end to the B end, the first claw is in a clamping state and the second claw is in a releasing state; when the transmission mechanism moves from the B end to the A end, the first claw is in a releasing state and the second claw is in a clamping state; or, when the transmission mechanism moves from the B end to the A end, the first claw is in a clamping state and the second claw is in a releasing state.

[0005] In the above scheme, two clamping jaws are used to hold the anchor cable. One of the jaws can transport the anchor cable through a reciprocating (i.e., stepping) motion, avoiding the risk of falling during the installation of long anchor cables, realizing the effective installation of long anchor cables, and solving the problem of difficult installation of long anchor cables in the upward hole.

[0006] Preferably, both end A and end B are provided with sensors for sensing the position of the transmission mechanism, and the sensors are electrically connected to the first gripper, the second gripper, and the transmission mechanism, respectively.

[0007] Preferably, the guide seat has a groove extending from end A to end B inside, and one side surface of the groove is a through opening, into which the transmission mechanism extends and is adapted to the groove.

[0008] Preferably, the anchor cable installation device further includes a wooden plug located beside the base, the wooden plug being positioned near end B, and the wooden plug having an anchor cable hole for the anchor cable to pass through.

[0009] Preferably, the wooden plug is further provided with a vent hole and a grouting hole. The axes of the vent hole and the grouting hole are parallel to the axis of the anchor cable hole.

[0010] Preferably, the B end is provided with a hydraulic cylinder that can extend a piston rod, and the extended piston rod contacts the wooden plug.

[0011] Preferably, the wooden plug is a truncated cone, with its smaller diameter end positioned away from end B.

[0012] Preferably, the base includes a base and a turntable rotatably disposed on the base, and the guide seat is disposed on the turntable.

[0013] Compared with related technologies, the beneficial effects of this utility model are as follows: 1. The anchor cable installation device adopts two clamping jaws to hold the anchor cable. One of the jaws can transport the anchor cable through a reciprocating (i.e., stepping) motion, avoiding the risk of falling during the installation of long anchor cables, realizing the effective installation of anchor cables, and solving the problem of difficult installation of long anchor cables in the upward hole. 2. The anchor cable installation device uses two clamps to hold the anchor cable, and the two clamps work alternately. This not only realizes the transport of the anchor cable, but also allows for reverse tensioning of the anchor cable, ensuring that the quality of its installation in the ascending hole meets the design requirements, and ensuring the quality and effect of the surrounding rock support. Third, the wooden plug is designed as a truncated cone structure, which is convenient to install and not easy to fall off, thus achieving reliable fixation. Attached Figure Description

This rotation can be achieved by a motor and a rotating shaft, a motor and a slewing bearing, a rotating shaft and manual operation, or other existing rotation structures. Self-locking requires a motor or other existing self-locking purchased components.

[0019] A guide seat 4 is mounted on the side surface of the turntable 12. The guide seat 4 is a long rectangle extending radially along the turntable 12. The guide seat 4 has an A end and a B end that are arranged opposite to each other. The interior of the guide seat 4 is provided with a groove 41 extending from the A end to the B end. One side surface of the groove 41 is a through opening (equal in length to the groove 41). The transmission mechanism 3 extends into the through opening and is adapted to the groove 41.

[0020] The transmission mechanism 3 can reciprocate between end A and end B relative to the slide 41. The transmission mechanism 3 can be implemented by means of a slider, a guide rail and a motor that outputs driving force; or, the transmission mechanism 3 can also be implemented by means of a motor and a lead screw; or, the transmission mechanism 3 can also be implemented by means of a gear, a rack and pinion and a motor that drives the gear to rotate, or other existing drive structures.

[0026] S2, the anchor cable 2 enters from the first clamp 5 and exits from the second clamp 6, and at the same time the controller activates the first clamp 5 and the second clamp 6 to clamp the anchor cable 2.

[0027] S3, rotate turntable 12 so that end B on guide seat 4 faces the wooden plug 8 and aligns anchor cable 2 with anchor cable hole 81, and lock the position of turntable 12.

[0028] S4, release the second clamp 6, start the transmission mechanism 3 to move towards end B, the anchor cable 2 is clamped by the first clamp 5 and enters the anchor cable hole 81 under the action of the transmission mechanism 3 and extends into the upward hole.

[0029] S5, when the displacement of the transmission mechanism 3 triggers the sensor 7 at end B, the sensor 7 sends a signal to the controller, the controller issues a command to stop the displacement of the transmission mechanism 3, starts the second gripper 6 to clamp the anchor cable 2, and releases the first gripper 5.

[0030] S6, restart the transmission mechanism 3 and move it in the opposite direction to the initial position (from end B to end A). At this time, the anchor cable 2 is held by the second gripper 6 to prevent the anchor cable 2 installed in the upward hole from falling or loosening.

[0031] S7, when the displacement of the transmission mechanism 3 triggers the sensor 7 at end A, the sensor 7 sends a signal to the controller, the controller stops the displacement of the transmission mechanism 3, and at the same time starts the first gripper 5 to clamp the anchor cable 2 and releases the second gripper 6.

[0032] Repeat steps S4-S7 until the installation of anchor cable 2 is completed. Then, after repeating step S6, proceed to step S8, start hydraulic cylinder 9, extend piston rod and abut against wooden plug 8, push wooden plug 8 into the upward hole to facilitate subsequent grouting.
