Steel wire mesh netting machine for coal mine anchor rod supporting

Abstract

The invention relates to a steel wire mesh netting machine for coal mine anchor rod supporting, belonging to the field of machinery, which comprises a main machine and a following machine, wherein the main machine is fixed on a base; the following machine moves back and forth on the orbit of the following machine; the main machine and the following machine are connected through a hydraulic cylinder and the following machine is pulled to move; all meshes penetrate through the shuttle bars of the main machine and the following machine; an oil cylinder is used for pushing the flowing machine to tension the meshes so that the meshes have tensile force; the main machine comprises a main machine frame, a shuttle bar mechanism, a mesh combing mechanism and a mesh pulling mechanism; the shuttle bar mechanism is arranged in front of the mesh combing mechanism; and the mesh pulling mechanism is arranged at the back of the mesh combing mechanism. A hexagonal wire mesh with thick meshes and small mesh openings can be knitted through the machine. The diameter of the knitted mesh is 3-4.5mm, and the width of the mesh opening is 50mm.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a wire mesh weaving machine for bolt support in coal mines, which is mainly used for weaving hexagonal wire mesh. Background technique [0002] Utility model patent ZL02220196.3 discloses a hexagonal mesh weaving mechanism. It adopts two staggered plates to move relative to each other, install several pairs of half gears in the opposite seams of the staggered plates, and use the rack to pull the half gears to rotate. There is a hole in each half gear, and the warp and weft threads are inserted into the holes. And the two wires are fixed on the netting cylinder, when the half gear is pulled and rotated by the rack, the two meshes are twisted mutually for two weeks, and then pulled out a certain distance by the netting cylinder. Afterwards, the staggered plates are staggered with each other, and the half gears are also staggered thereupon. At the same time, pull the mesh to m...

AI Technical Summary

Problems solved by technology

[0003]①The edge of the woven hexagonal mesh is curved, and the hexagonal mesh with straight mesh edges cannot be woven

[0004]②The number of twisting turns of the two mesh wires is limited by the stroke of the rack, generally only two turns

[0005]③The tension cannot be controlled when the two wires are twisted. For the woven hexagonal mesh, the tension of the wires is uneven and there is no prestress in the wires.

Affect the overall carrying capacity of the network

[0007]⑤ Among each pair of half gears, only one half gear is connected with the spring wire barrel storing the weft thread, and the half gear also drives the spring wire barrel while twisting the net Eccentric rotation makes the machine run unstable and poor in safety

[0009]⑦This kind of net weaving mechanism can only weave thin wire mesh because a pair of half gears can only transmit a small torque, and the diameter of the mesh is generally less than 3mm

It cannot weave large-diameter mesh wire hexagonal mesh, and cannot meet the engineering needs for large-diameter hexagonal mesh

[0010] In short, the hexagonal mesh machine mechanism and weaving method currently in use cannot weave large-diameter mesh, with straight mesh edges, and mesh with good straightness and Prestressed hexagonal mesh

Thus limiting the wide application of hexagonal mesh
