Compared with traditional binding or limiting plate fixation, the operation is faster and reduces manual intervention.

Description

Technical Field

[0001] This utility model relates to the field of anchor cable transportation, and more specifically, to an anchor cable transportation device for coal mines. Background Technology

[0002] Coal mine anchor cables are active support devices used for reinforcing surrounding rock in mine tunnels. They consist of steel strands, anchorages (such as wedge-type anchorages), anchoring agents (resin or mortar), and accessories such as support trays. They apply prestress to the surrounding rock through mechanical tensioning, anchoring unstable rock strata to deeper, stable rock layers, forming a rigid roof structure and effectively preventing collapse. The anchor cable consists of an inner anchor head (anchoring section) and an outer anchor head (tensioning section). The inner anchor head is fixed mechanically or by adhesive bonding (resin / mortar), while the outer anchor head is secured by anchorages to lock the prestress. Its static load anchoring efficiency coefficient is ≥0.95, and its pull-out force can reach over 157.5 kN. It is suitable for complex conditions such as fractured roofs and high-stress tunnels, featuring high strength, deep anchoring, and active support.

[0003] In the existing technology, when transporting anchor cable rolls, the complex environment and rugged roads in coal mines make the anchor cable rolls prone to slipping when subjected to bumps or tilts, leading to instability in the placement of the anchor cable rolls and increasing safety hazards. Therefore, we have made improvements to this issue and proposed an anchor cable transport device for coal mines. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the solution of this utility model:

[0017] 1. By setting up a mechanism where the rotation of a first handwheel drives the rotation of a first connecting shaft, which in turn drives the rotation of a first bidirectional lead screw, which in turn drives the movement of a first slider, which in turn drives the movement of a first outer support plate, which in turn drives a rubber pad, bringing the rubber pad into contact with the inner wall of the anchor cable roll; and the rotation of a second handwheel drives the rotation of a second connecting shaft, which in turn drives the rotation of a second bidirectional lead screw, which in turn drives the movement of a second slider, which in turn drives the movement of a second outer support plate, which in turn drives the rubber pad, bringing the rubber pad into contact with the inner wall of the anchor cable roll, thus forming a flexible clamping mechanism. This mechanism not only secures the anchor cable roll during transportation but also simplifies the operation, solving the problem in existing technologies where anchor cable rolls are prone to slippage when subjected to bumps or tilting, leading to instability in the placement of the anchor cable roll.

[0032] Example:

[0033] like Figure 1-7 As shown, this embodiment proposes an anchor cable transport device for coal mines, including a platform 1. A placement seat 2 for placing anchor cable rolls is provided above the platform 1. A first U-shaped seat 3 is fixedly installed on the top of the platform 1. A first bidirectional lead screw 4 is rotatably connected to the first U-shaped seat 3. First sliders 5 are threaded to the threads at both ends of the first bidirectional lead screw 4. Rotation of the first bidirectional lead screw 4 drives the first sliders 5 to move. A first outer support plate 6 is fixedly installed on the top of the first slider 5. Movement of the first slider 5 drives movement of the first outer support plate 6. A second U-shaped seat 7 is fixedly installed on the top of the platform 1. A second U-shaped seat 7 is rotatably connected to... The second bidirectional lead screw 8 has a second slider 9 threadedly connected to both ends. Rotation of the second bidirectional lead screw 8 moves the second slider 9. A second outer support plate 10 is fixedly installed on the top of the second slider 9. Movement of the second slider 9 moves the second outer support plate 10. A protective mechanism is provided on the outer wall of the outer support plate. A first drive mechanism is provided at the end of the first bidirectional lead screw 4, driving the first bidirectional lead screw 4. A second drive mechanism is provided at the end of the second bidirectional lead screw 8, driving the second bidirectional lead screw 8. A connecting mechanism is provided on the platform 1, and a moving mechanism is provided at the bottom of the platform 1. After a period of use, the two bidirectional lead screws need to be regularly maintained by personnel, such as applying lubricating oil. A lead screw guard can also be installed to prevent dust from affecting the bidirectional lead screws, depending on the actual usage environment.

[0034] The protective mechanism includes a rubber pad 11 bonded to the outer ends of the first outer support plate 6 and the second outer support plate 10. The outer support plate 10 drives the rubber pad 11 to contact the inner wall of the anchor cable roll, forming a flexible clamp.

[0035] The first driving mechanism includes a first connecting shaft 12 fixedly installed at the end of the first bidirectional lead screw 4. A first handwheel 13 is fixedly installed on the first connecting shaft 12. The rotation of the first handwheel 13 drives the first connecting shaft 12 to rotate, and the rotation of the first connecting shaft 12 drives the first bidirectional lead screw 4 to rotate.

[0036] The second drive mechanism includes a second connecting shaft 14 fixedly installed at the end of the second bidirectional lead screw 8. A second handwheel 15 is fixedly installed on the second connecting shaft 14. The rotation of the second handwheel 15 drives the second connecting shaft 14 to rotate, and the rotation of the second connecting shaft 14 drives the second bidirectional lead screw 8 to rotate.

[0037] The connecting mechanism includes a connector 17 fixedly installed on the side wall of the platform 1. The connector 17 is used to connect with an external moving device to facilitate pulling the transport device (or the device can be installed on the top of the transport device and the moving wheels can be removed, depending on the actual use).

[0038] A base 16 is fixedly installed at the bottom of the placement seat 2, and the base 16 is fixedly installed on the top of the platform 1.

[0039] Specifically, when using the anchor cable transport device for coal mines: the anchor cable roll is placed on the outer support plate and stably on the placement seat 2. Then, the first handwheel 13 is rotated, which drives the first connecting shaft 12 to rotate. The first connecting shaft 12 drives the first bidirectional lead screw 4 to rotate, which drives the first slider 5 to move. The first slider 5 moves the first outer support plate 6, which moves the rubber pad 11, making the rubber pad 11 contact the inner wall of the anchor cable roll. Next, the second handwheel 15 is rotated, which drives the second connecting shaft 14 to rotate. The second connecting shaft 14 drives the second bidirectional lead screw 8 to rotate, which drives the second slider 9 to move. The second slider 9 moves the second outer support plate 10, which moves the rubber pad 11, making the rubber pad 11 contact the inner wall of the anchor cable roll, forming a flexible clamp. This effectively prevents the anchor cable roll from sliding or rolling due to bumps or tilting during transportation. Compared with traditional binding or limiting plate fixation, the operation is faster and reduces manual intervention. The handwheel on the double-acting lead screw can be secured with a bolt to prevent the double-acting lead screw from loosening (this can be set according to requirements).

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
