Description

Technical Field

[0001] The invention relates to an anchor cable limiting device, in particular to a limiting device capable of preventing an anchor cable from falling. Background Art

[0002] Anchor cables are often used for supporting mine tunnels. The anchor cables are multi-strand steel bundle structures, and the length of mining anchor cables is usually 6-12 meters. Anchor cables are important supporting materials for mining production and are used in large quantities. In actual use, anchor cables are easy to slip out from the upper openings of mining cars, floats and other vehicles due to displacement. Summary of the invention

[0003] The purpose of the present invention is to provide an anchor cable limiting device, which solves the problem of anchor cables falling off during transportation.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is:

[0005] An anchor cable limiting device comprises a first limiting portion, a second limiting portion and a column, wherein the first limiting portion is vertically fixed to one side of the column, and the second limiting portion is fixed to the other side of the column relative to the first limiting portion.

[0006] Furthermore, the first limiting portion and the second limiting portion have the same structure, both comprising limiting plates, and the limiting plates are symmetrically distributed on both sides of the column; the limiting plates are evenly provided with a plurality of saw teeth along the vertical direction.

[0007] Furthermore, the column is provided with a plurality of limiting holes along the vertical direction, and the limiting holes penetrate the column.

[0008] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0009] The present invention connects the limiting device to a pallet on which the anchor cable is placed, and connects the limiting device at a designated position of the pallet. The serrations on the first limiting part and the second limiting part can effectively increase the friction between the anchor cable and the serrations, thereby limiting the horizontal movement of the anchor cable. The limiting hole on the column is connected with an anchor rod, and both ends of the anchor rod are threaded. The anchor rod is detachably fixed to the column by a nut. The anchor rod is located above the anchor cable, thereby effectively limiting the vertical movement of the anchor cable. The present invention can effectively limit the degree of freedom of the anchor cable during transportation, and prevent the anchor cable from falling and increasing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] like Figures 1 to 3 As shown, an anchor cable limiting device comprises a first limiting portion 1, a second limiting portion 2 and a column 3, wherein the first limiting portion 1 is fixed on one side of the column 3 in the vertical direction, and the second limiting portion 2 is fixed on the other side of the column 3 relative to the first limiting portion 1. The first limiting portion 1 and the second limiting portion 2 have the same structure, and both comprise limiting plates, wherein the limiting plates are symmetrically distributed on both sides of the column 3; the limiting plates are evenly provided with a plurality of saw teeth 4 in the vertical direction. The column 3 is provided with a plurality of limiting holes 5 in the vertical direction, and the limiting holes 5 penetrate the column 3. The limiting device will be evenly placed along the four sides of the rectangular chassis where the anchor cable is stored, firstly, a plurality of limiting devices are evenly placed along the first long side of the rectangular chassis, and then a plurality of limiting devices corresponding to the limiting devices on the first long side are placed on the opposite side of the first long side, so as to make the limiting holes 5 correspond one to one. A plurality of limiting devices are evenly placed on the first short side of the rectangular chassis, and then a plurality of limiting devices corresponding to the limiting devices on the first short side are placed on the opposite side of the first short side, so as to make the limiting holes 5 correspond to each other. The bottom of the column 3 is fixedly connected to the rectangular chassis, and the saw teeth 4 on the first limiting part 1 and the second limiting part 2 face the inner side of the rectangular chassis.

[0014] After the anchor cable is placed on the rectangular chassis, it is necessary to transport the rectangular chassis with the anchor cable to the place of use by a transport vehicle. However, the road conditions in the coal mine are not smooth, which will cause the anchor cable to fall during transportation. After the device is installed on the rectangular chassis, when the anchor cable moves in the horizontal direction due to inertia, the saw teeth 4 located on both sides of the rectangular chassis will limit the movement of the anchor cable to prevent the anchor cable from falling. Similarly, when encountering bumpy road conditions, the saw teeth 4 will still provide friction for the anchor cable, and the anchor rod will directly limit the range of motion of the anchor cable in the vertical direction to prevent the anchor cable from falling and reduce work efficiency.

[0015] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
