Description

Technical Field

[0001] The utility model belongs to the technical field of underground mine construction equipment, in particular to a lifting device for drilling assembled cable board cards. Background Art

[0002] With the widespread use of power cables in distribution lines, the introduction of power cables in underground mine operations has brought convenience to users on the one hand, but on the other hand, there are still many problems.

[0003] Currently, a single-cage clamp method—one hole, one rope, and one cable—is commonly used to secure cables in underground mine construction. Due to the limited working space underground in mines, the inner diameter of the cable hole is generally small, resulting in limited clearance within the cable hole. This makes lowering, hanging, and hoisting operations within the cable hole prone to entanglement between the cable and the wire rope, creating significant difficulties. Furthermore, due to the heavy weight of the cable itself, the single-cage clamp method poses a risk of slipping during lowering, hanging, and hoisting, and also prolongs the construction period. Utility Model Content

[0004] The utility model aims to provide a lifting device for a drilled assembled cable plate card, which can ensure that the cable is not easy to slip during the lowering, hanging and lifting processes and shorten the construction period.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A lifting device for a drilled assembled cable plate card includes a steel wire rope and two cables. The steel wire rope is located between the two cables. The two cables are fixed to the steel wire rope through multiple cable plates, and the cable plates connecting the steel wire rope and one cable are alternately arranged with the cable plates connecting the steel wire rope and another cable.

[0007] The utility model lifting device has the following advantages:

[0008] (1) By alternately connecting a steel wire rope with two cables, a dual-cable operation mode is achieved. The two cables restrain each other, ensuring that the cables fixed on the steel wire rope are not likely to slip; and workers can simultaneously transmit two cables, which not only speeds up the construction speed and reduces the construction period by half, but also solves the problem of the extra weight of a cable, reduces labor intensity, and saves costs.

[0009] (2) Use clamps to fix the wire rope and cable on both sides of the base so that the base is always located in the center of the cable plate and the cable hole during the process of lowering, hanging and lifting the cable, saving space and effectively reducing the friction between the cable plate and the cable hole wall.

[0010] (3) By coating the inner wall of the clamp with rubber, the cable is not easily damaged during the process of lowering, hanging and lifting.

[0011] (4) When the diameter of the cable and wire rope allows, the cable plate can be adapted to various sizes of cable holes by adjusting the base and clamp size, thereby achieving the feasibility of constructing multiple cables in one hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0016] See Figure 1 The utility model lifting device includes a wire rope 3 and two cables 2. The wire rope 3 is located between the two cables 2. The two cables 2 are fixed to the wire rope 3 through multiple cable card clips 1 respectively, and the cable card clips 1 connecting the wire rope 3 and one cable 2 and the cable card clips 1 connecting the wire rope 3 and another cable 2 are alternately arranged. A guide pendant 4 is hung at the end of the wire rope 3.

[0017] like Figure 2 As shown, the cable plate clamp 1 in the lifting device of the utility model includes a base 8, two clamps 6 and multiple bolts 7; the clamp 6 includes a saddle-shaped clamp, and connecting plates are fixed on both sides of the clamp, and each connecting plate is processed with at least one through hole; the base 8 is plate-shaped, and multiple screw holes 9 are processed on it, and the number of screw holes 9 is the same as the total number of through holes on the two clamps 6.

[0018] When in use, the two clamps 6 are respectively arranged on both sides of the base 8, and the two clamps 6 are staggered, with one clamp 6 being sleeved on the cable 2 and the other clamp 6 being sleeved on the wire rope.

[0019] The base 8 and the clamp 6 need to be heat treated to enhance toughness.

[0020] While ensuring that the cable plate card 1 passes through the cable hole 5 smoothly, in order to reduce the friction between the cable plate card 1 and the wall of the cable hole 5 during construction, the base 8 and the clamp 6 are set to have rounded corners on all sides, which not only saves space but also reduces the possibility of blockage in the cable hole 5 and the difficulty of transmission.

[0021] In order to prevent the cable board 1 from damaging the outer sheath of the transmitted cable 2, the inner wall of the clamp is covered with rubber.

[0022] When using the lifting device of the utility model, first, place the wire rope 3 on flat ground, and then place a cable 2 on each side of the wire rope 3. Take a cable plate 1, place one end of the base 8 under a cable 2, fasten the clamp 6 so that the cable 2 is located in the clamp of the clamp 6, and connect the clamp 6 and base 8 with bolts 7; then place the other end of the base 8 above the wire rope 3, take another clamp 6, and fasten it to the wire rope 3 so that the wire rope 3 is clamped in the clamp of the other clamp 6, connect the other clamp 6 and base 8 with bolts 7, and then evenly tighten all bolts 7.

[0023] After installing one cable plate 1, place the end of the lifting device into the cable hole 5, start the power, rotate the cable drum, and slowly lower the cable into the cable hole 5. Then, use the same method as above to fix the wire rope 3 with another cable 2 to the second cable plate 1. During the lowering process, follow the principle of connecting one wire rope 3 with two cables 2 at equal intervals, and repeatedly install multiple cable plates 1 between one wire rope 3 and two cables 2 until the cables in the cable drum are lowered to the required height. After the construction is completed, start the power, rotate the cable drum in the opposite direction, remove the fasteners fixing the cables one by one, and lift the cables and retract them into the cable drum.

[0024] The distance between two adjacent cable boards 1 is equal. For example, if the distance between two adjacent cable boards 1 is 3 meters, then the distance between two adjacent cable boards 1 connected to the same cable 2 is 6 meters.
