Background Art

[0002] Mine anchor cables are the main support materials to ensure the stability of surrounding rocks in coal mine tunnels. Due to the long length of the anchor cable, it can be deeply anchored into the deep and relatively stable surrounding rocks, and a large preload can be applied, so it can achieve a good support effect, greatly improving the overall level of tunnel support, and playing an important role in ensuring safe production. At present, the anchor cables purchased by the mine are usually in coils. When using them, it is necessary to find the rope head first, and then cut the anchor cables of different lengths according to actual production needs. However, due to the large elasticity of the anchor cable, after cutting, the rope head will rotate due to inertia, making it impossible to limit the rope head. When cutting again, it is necessary to manually find the rope head, which is time-consuming and laborious; and during the rotation process, the rope head will twist or swing, which may injure nearby workers, posing a major safety hazard.

The above-mentioned rope release device is achieved by integrally mounting the anchor rope drum on the inner support rod on the turntable, and a bearing is installed at the bottom, which drives the turntable to rotate when the anchor rope is pulled out; the baffle on the central axis plays a role in fixing the rope drum and preventing the anchor rope from catapulting when it is pulled out, which can reduce the situation of injuring nearby workers and reduce safety hazards. However, after the above-mentioned rope releasing device cuts the anchor rope, the rope head will rotate due to inertia, and the rope head cannot be limited. When cutting again, it is necessary to manually find the rope head, which is time-consuming and laborious. Summary of the invention

Embodiment 2

[0093] The difference between this embodiment and embodiment 1 is that one end of the rotating shaft (10) is hinged to the limiting bottom ring (5) via a hinge seat (29), and the other end of the rotating shaft (10) is snap-connected to the limiting top ring (1); when in use, the other end of a portion of the rotating shaft (10) is removed from the limiting top ring (1), one end of the rotating shaft (10) is rotated to the ground via the hinge seat (29), the limiting cap (16) is removed from the rotating support column (15), the support plate (6) is moved out of the limiting bottom ring (5) via the locking universal wheel (9), the anchor rope drum is placed on the rotating support column (15), and then the support plate (6) is moved to the center of the limiting bottom ring (5) via the locking universal wheel (9), so that the anchor rope drum can be easily placed on the rotating support column (15);

[0094] The anti-slip grooves on the limiting slide groove (14) can increase the friction between the anchor rope and the limiting slide groove (14), reduce the sliding between the anchor rope and the limiting slide groove (14), and ensure that the anchor rope can accurately and quickly pass through the limiting slide groove (14) and reach the target position; at the same time, when the anchor rope is swung, it plays a role in increasing resistance and reducing the swirling of the anchor rope;

[0095] The coordinated design of the steering groove (12), the steering ball (13) and the limiting slide groove (14) enables the anchor rope to flexibly adjust its direction when passing through the limiting slide groove (14), so that the anchor rope reaches the target position in different directions, thereby reducing friction and damage caused by improper traction direction; at the same time, it plays a limiting role when the anchor rope is cut and swung back, thereby reducing the time for finding the rope head;

[0096] There are a plurality of locking universal wheels (9), and the plurality of locking universal wheels (9) are arranged equidistantly along the circumferential direction of the connecting edge (8). When the rotating support column (15) rotates, the locking universal wheels (9) are locked, thereby reducing the shaking of the support plate (6); at the same time, the forces on the edge and the center of the support plate (6) can be balanced, thereby reducing the support of the support plate (6) on the anchor cable drum and the tilting caused by the anchor cable drum when rotating;

[0097] The limiting roller (4) is designed to be sleeved on the side of the rotating shaft (10) through a through hole opened in the middle, and the limiting roller (4) can rotate relative to the rotating support column (15) through the rotating shaft (10), thereby reducing the twisting and swinging of the anchor rope when the anchor rope is swung, thereby reducing the risk of injuries to nearby personnel;

[0098] The limiting cap (16), the limiting rod (2) and the reinforcing rod (3) are designed to cooperate with each other. When the other end of the rotating support column (15) rotates on the supporting plate (6) via the supporting bearing (23), the limiting cap (16) can limit one end of the rotating support column (15) to prevent the one end of the rotating support column (15) from swinging. The limiting rod (2) and the reinforcing rod (3) can limit the limiting cap (16) to prevent the limiting cap (16) from rotating under the rotation of the rotating support column (15).

[0099] The anti-deflection column (24) and the anti-deflection ball (25) are designed to cooperate with each other. When the ratchet (26) rotates under the drive of the rotating support column (15), the anti-deflection ball (25) and the bottom edge of the ratchet (26) contact each other, thereby ensuring the stability and directionality of the ratchet (26) during the rotation process and reducing the shaking of the ratchet (26);

[0100] The ratchet (26), the ratchet (26) column (21), the return spring (28) and the sliding rod (18) are designed to cooperate with each other. When the anchor rope is pulled out, the rotating support column (15) drives the ratchet (26) to rotate. The return spring (28) and the sliding rod (18) provide a meshing force and a restoring force between the ratchet (26) column (21) and the ratchet (26), so that the ratchet (26) column (21) reciprocates. The ratchet (26) can only rotate in one direction. When the anchor rope is cut, the anchor rope rotates due to inertia and drives the rotating support column ( When the ratchet (26) is reversed, the ratchet (26) column (21) can prevent the ratchet (26) from reversing, thereby generating a braking force on the reversal of the rotating support column (15), thereby reducing the rapid rotation of the anchor rope, so that the rope end can be quickly found when it is used next time, reducing the time for finding the rope end; at the same time, when it is necessary to change the rotation direction of the ratchet (26), the sliding rod (18) can be manually rotated to change the direction of the arc surface of the ratchet (26) column (21), so that the ratchet (26) can rotate in the opposite direction, thereby realizing the switching of the forward and reverse directions of the ratchet (26);

[0101] The purpose is to drive the rotating assembly to rotate when the anchor rope is pulled out, reduce the deflection of the rotating assembly through the limit assembly, and drive the self-locking assembly to rotate in one direction through the rotating assembly. When the anchor rope is rotated, the self-locking assembly can limit the reversal of the rotating assembly, so as to quickly find the rope head when it is used again.

[0102] It should be noted that, unless otherwise clearly stipulated and defined, the terms "placed", "connected", and "joined" should be understood in a broad sense. For example, it can be fixed connection methods such as hemmed connection, rivet connection, pin connection, adhesive connection, and welding connection, or detachable connection methods such as threaded connection, snap connection, and hinge connection, or integral connection, or electrical connection, or directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
