Description

Technical Field

[0001] This utility model relates to the field of mine anchor cable conveying, and in particular to a pneumatic mine anchor cable bending machine. Background Technology

[0002] As the mining depth increases, the support strength becomes higher and higher, and mining anchor cables are widely used. In order to facilitate the loading and transportation of mining anchor cables, they need to be bent, tied and shaped after processing.

[0003] Previously, most anchor cables were bent and tied manually. The main risks were that the steel strands were highly elastic, and there was a risk of injury from the strands rebounding during manual bending. In addition, manual bending of mining anchor cables required 4-6 people, which was inefficient and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to provide a pneumatic mining anchor cable bending machine to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a pneumatic mining anchor cable bending machine, comprising a base plate, a mounting base, a cylinder, a cylinder control unit, a bending guide head, a limiting guide rail, a pad, a guide wheel assembly, and a safety limiting cable. The mounting base is fixed at the rear top of the base plate. The cylinder is mounted on the mounting base. The cylinder control unit is mounted on the top of the mounting base. The bending guide head is mounted at the front end of the cylinder output end. The limiting guide rail is mounted at the front top of the base plate, and the bending guide head can slide back and forth along the limiting guide rail. The middle of the pad is fixed to the front bottom of the base plate. The left and right guide wheel assemblies are respectively fixed to the left and right sides of the base plate through the top of the pad. The safety limiting cable is fixed to the upper side of the base plate through the left and right guide wheel assemblies.

[0006] Based on the above technical solution, the guide wheel assembly includes a fixed plate, an anchor cable support plate, a rotating shaft, a pulley, a guide groove, and a torsion spring shaft. The fixed plate is placed vertically, the anchor cable support plate is fixed to the rear end of the bottom fixed plate, the rotating shaft is installed on the left and right sides between the upper and lower fixed plates, the left and right pulleys are respectively installed on the left and right rotating shafts, the guide groove is opened on the side end of the pulley, the middle part of the torsion spring shaft is fixed to the outside of the upper and lower fixed plates, and the torsion spring shaft is torsionally connected to the top of the pad block, and the left and right ends of the safety limit cable are respectively fixed to the upper part of the side end of the left and right torsion spring shafts.

[0007] Based on the above technical solution, the torsion spring shaft is kept perpendicular to the base plate by a torsion fixing plate.

[0008] Compared with existing technologies, this invention has the following advantages: This invention uses a cylinder in conjunction with left and right guide wheel assemblies on the base plate to push out the anchor cable, achieving the bending action and forming the anchor cable by bending, without the need for manual intervention. The separation of human and machine operations results in a high safety factor. Attached Figure Description

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1 to 3 As shown, a pneumatic mining anchor cable bending machine includes a base plate 1, a mounting base 2, a cylinder 3, a cylinder control unit 4, a bending guide head 5, a limiting guide rail 6, a pad block 7, a guide wheel assembly 8, and a safety limiting cable 9. The mounting base 2 is fixed to the rear top of the base plate 1. The cylinder 3 is mounted on the mounting base 2. The cylinder control unit 4 is mounted on the top of the mounting base 2. The bending guide head 5 is mounted at the front end of the output end of the cylinder 3. The limiting guide rail 6 is mounted on the front top of the base plate 1, and the bending guide head 5 can slide back and forth along the limiting guide rail 6. The middle of the pad block 7 is fixed to the front bottom of the base plate 1. The left and right guide wheel assemblies 8 are respectively fixed to the left and right sides of the base plate 1 through the top of the pad block 7. The safety limiting cable 9 is fixed to the upper side of the base plate 1 through the left and right guide wheel assemblies 8.

[0015] The guide wheel assembly 8 includes a fixed plate 10, an anchor cable support plate 11, a rotating shaft 12, a pulley 13, a guide groove 14, and a torsion spring shaft 15. The fixed plate 10 is placed vertically, and the anchor cable support plate 11 is fixed to the rear end of the bottom fixed plate 10. The rotating shaft 12 is installed on the left and right sides between the upper and lower fixed plates 10, and the two pulleys 13 are installed on the left and right rotating shafts 12 respectively. The guide groove 14 is opened on the side end of the pulley 13. The middle part of the torsion spring shaft 15 is fixed to the outside of the upper and lower fixed plates 10, and the torsion spring shaft 15 is torsionally connected to the top of the pad 7. The left and right ends of the safety limit cable 9 are respectively fixed to the upper part of the side ends of the left and right torsion spring shafts 15.

[0016] The torsion spring shaft 15 is kept perpendicular to the base plate 1 by the torsion fixing plate 10.

[0017] The working principle of this utility model is as follows: In use, the anchor cable to be bent is placed perpendicularly to the base plate 1 via the anchor cable support plate 11. The cylinder 3 is activated by the cylinder control unit 4, pushing the bending guide head 5 forward. Under the action of the bending guide head 5, the middle part of the anchor cable is pushed forward and bent along the limiting guide rail 6. The left and right parts of the anchor cable are guided forward by the pulleys 13 and guide grooves 14. Under the reaction force of the anchor cable, the left and right guide wheel sets 8 rotate clockwise with the anchor cable, using the torsion spring shaft 15 as the fulcrum. The right guide wheel set 8 rotates counterclockwise with the anchor cable. This achieves the bending and shaping of the anchor cable, while the safety limiting cable 9 prevents accidental ejection of the anchor cable for securing it. The bending process requires no manual intervention. The separation of man and machine ensures a high safety factor.

[0018] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
