Description

Technical Field

[0001] The utility model belongs to the technical field of anchor cable equipment and relates to an underground long anchor cable steel strand cutting device. Background Art

[0002] Underground mines face complex geological conditions, with fractured surrounding rock and high ground stress. Medium- and long-length anchor cables are often deployed in weak rock formations. During the pulling process, the steel strands used in long anchor cables must be bundled into coils and secured with steel bands. Each strand of long anchor cable is 6 meters long, requiring manual shearing. However, shearing coils is difficult, and once the binding bands are cut, the strands unravel with tremendous force, potentially causing injuries and posing a safety risk. Safely shearing the strands to minimize accidents is a major challenge in long anchor cable construction. Utility Model Content

[0003] The purpose of the utility model is to provide an underground long anchor to solve the problems existing in the prior art.

[0004] To this end, the present invention adopts the following technical solutions:

[0005] A device for cutting long underground anchor cable strands comprises a bracket, a support rod detachably provided on the bracket, an upper stop rod detachably provided above the support rod, the upper stop rod being mounted on the bracket, a side stop member being provided on each side of the support rod in the longitudinal direction, and the stop rod being fixed to the bracket.

[0006] Furthermore, the support rod is arranged horizontally.

[0007] Furthermore, the bracket is provided with a first fastening hole, and the bracket is provided with a second fastening hole opposite to the first fastening hole away from the first fastening hole. One end of the support rod is located in the first fastening hole, and the other end is located in the second fastening hole.

[0008] Furthermore, the side block includes a plurality of side block rods arranged in an arc shape, and the side block rods and the support rods are arranged parallel to each other.

[0009] Furthermore, the bracket is provided with a first mounting hole, and a second mounting hole corresponding to the first mounting hole is provided on a side of the bracket away from the first mounting hole, and both ends of the upper blocking rod are respectively located in the first mounting hole and the second mounting hole.

[0010] Furthermore, the upper blocking rod and the support rod are arranged parallel to each other.

[0011] The beneficial effects of the present invention are as follows: a detachable support rod is provided on the bracket, and the coiled steel strand is put on the support rod. The restriction of the upper side block and the upper block rod of the bracket can prevent the coiled steel strand from breaking when the binding steel belt is cut, causing harm to the surrounding personnel, and the steel strand can be directly pulled out for use after cutting, which is convenient and quick; the structure is simple and the manufacturing cost is low.

[0015] The utility model is described in detail below with reference to the accompanying drawings:

[0016] like Figure 1 As shown, a downhole long anchor cable steel strand cutting device includes a bracket 1, a horizontally arranged support rod 2 is detachably provided on the bracket 1, the bracket 1 and the support rod 2 are both made of stainless steel, the support rod 2 can pass through the middle of the disc-shaped steel strand to support the disc-shaped steel strand, specifically, a first clamping hole 3 is provided on the bracket 1, and a second clamping hole 4 opposite to the first clamping hole 3 is provided on the bracket 1 away from the first clamping hole 3, one end of the support rod 2 is located in the first clamping hole 3, and the other end is located in the second clamping hole 4. When installing, it is only necessary to insert the support rod 2 into the first clamping hole 3 and the second clamping hole 4, which is convenient and quick. A detachable upper blocking rod 5 is provided above the support rod 2, and the upper blocking rod 5 is installed on the bracket 1 and connected to the support rod 2 are arranged parallel to each other, and the upper block rod 5 is used to limit the disc-shaped steel strand from collapsing upward when it is cut. A first mounting hole 6 is provided on the bracket 1, and a second mounting hole 7 corresponding to the first mounting hole 6 is provided on the side of the bracket 1 away from the first mounting hole 6. The two ends of the upper block rod 5 are respectively located in the first mounting hole 6 and the second mounting hole 7. A side block 8 is provided on each side of the length direction of the support rod 2. The side block 8 is fixed to the bracket. The side block 8 includes a plurality of side blocks 801. In this embodiment, three side blocks 801 are provided and arranged in an arc shape from top to bottom. The side blocks 801 and the support rod 2 are arranged parallel to each other. The side blocks 801 are used to prevent the disc-shaped steel strand from collapsing to both sides when shearing, which can play a safety protection role.

[0017] The usage of this utility model is as follows:

[0018] Before use, first remove the upper blocking rod 5 and the support rod 2 from the bracket 1, and then place the disc-shaped steel strand into the bracket 1. Specifically, use a crane or other conventional equipment to place the disc-shaped steel strand between the two side blocking members 8, and then install the support rod 2. During installation, first insert one end of the support rod 2 into the first fixing hole 3, then pass it through the middle of the disc-shaped steel strand, and finally insert the support rod 2 into the second fixing hole 4, so that the support rod 2 supports the disc-shaped steel strand, that is, the disc-shaped steel strand is put on the support rod. On the rod 2, finally place the two ends of the upper blocking rod 5 into the first mounting hole 6 and the second mounting hole 7. After the installation is completed, the operator can cut the binding steel belt of the disc-shaped steel strand. Due to the restrictions of the side blocks 8 and the upper blocking rod 5, the disc-shaped steel strand can be blocked by the side blocks 8 after it collapses, effectively limiting the collapse range of the disc-shaped steel strand to between the two side blocks 8 and the position below the upper blocking rod 5, preventing the disc-shaped steel strand from collapsing too much and causing damage to the surrounding operators. In addition, the steel strand can be directly pulled out for use after cutting, which is convenient and quick.
