Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a curved edge structure of an underground mine support anchor net. Background Art

[0002] The underground support anchor net of the mine is used in conjunction with the anchor rod. The anchor rod is used to firmly install the anchor net on the roof or side wall of the mine shaft to achieve the effect of reinforcing the rock wall and ensuring safe underground operations. The anchor net is mostly used in specifications of 100mm×200mm. Two nets need to overlap each other by 200mm-300mm when splicing. If there is no overlap or too little overlap, the edge of the anchor net will be scattered due to the force when the anchor rod is driven, resulting in a waste of 10-30% of the area of ​​the anchor net, and it will not play a role in safe support. In order to facilitate the splicing of the support anchor net, the support anchor net is usually made into a curved edge. On the one hand, it is more convenient to hang the hook during splicing, and it will not be separated and disconnected, ensuring the support effect; on the other hand, the splicing does not need to overlap too much area, and the edge hanging saves anchor net materials and reduces costs.

[0003] There are many production lines for support anchor nets. The bent-edge support anchor nets are manually bent twice, which is too labor-intensive and has limited efficiency. For the workload of support anchor nets required for large-scale mine operations, the labor cost is relatively high, and the bending directions of adjacent steel bars of qualified support anchor nets are staggered. Conventional bending machines need to repeatedly adjust the position of the anchor nets when bending the support anchor nets, which is not suitable for the production line of support anchor nets with continuous output. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a curved edge structure of an underground mine support anchor net that replaces manual bending operations, adapts to the assembly line production of support anchor nets, and improves the production efficiency of curved edge support anchor nets.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a bending edge structure of an underground mine support anchor net, including a bending component and a driving component distributed on both sides and arranged oppositely;

[0006] The bending assembly comprises two sets of bending machines with opposite bending directions and spaced apart on one side, and the bending directions of the opposite bending machines are opposite;

[0007] The driving assembly includes a slide rail extending outwardly on both sides, a driving seat and a driving member. The bending assembly is arranged on the driving seat, and the driving seat is slidably arranged on the slide rail. The driving member is connected to the driving seat and causes the driving seat to linearly translate and reciprocate.

[0008] The beneficial effects of the above technical solution are: the bending components are arranged on both sides of the support anchor net, and the support anchor net or the bending equipment does not need to be moved, which can adapt to the assembly line operation of the support anchor net, reduce the labor of bending the support anchor net, and improve the efficiency of bending the support anchor net; the bending directions of the opposite bending machines are opposite, which can ensure that the interfaces of the formed bent support anchor net are staggered when spliced ​​in the mine shaft, saving the overlapping area and the fitting position is not easy to separate; the bending components are provided with bending directions opposite to each other. Two sets of bending machines can ensure that the adjacent sides of the formed curved support anchor net are hooked in an interlaced manner, thereby ensuring that the entire anchor net structure is stable and will not easily fall apart; at the same time, four sets of bending machines with opposite bending directions are arranged on the side of the support anchor net, which can complete the bending of the support anchor net in one process of assembly line production, and there is no need to turn the support anchor net over to form staggered curved edges. This can not only ensure that the quality of the support anchor net with staggered curved edges is qualified, but also improve the production and processing efficiency of the curved support anchor net.

[0009] Furthermore, the bending machine includes a gear, a rack and a lifting cylinder. A notch is opened on the gear, and a groove is opened on the driving seat in a direction perpendicular to the notch. The gear is rotatably set on the driving seat, the rack is meshed with the gear, and the bottom of the rack is fixedly connected to the lifting cylinder.

[0010] Beneficial effect: the lifting cylinder drives the rack to move, the rack can drive the gear to rotate, and the steel bar head inserted into the gear slot is rotated and bent with the torque of the gear rotation.

[0011] Furthermore, the extension distance of the telescopic end of the lifting cylinder is equal to the distance moved by the rack driving the gear to rotate 180 degrees.

[0012] Beneficial effect: When the lifting cylinder completes one extension or contraction, the rack rotates 180 degrees with the gear, and the steel bar head inserted into the gear slot is bent 180 degrees upward or downward to ensure that the supporting anchor net is bent.

[0013] Furthermore, for the two groups of bending machines with opposite bending directions, one group of lifting cylinders is in an initial contracted state, and the other group of lifting cylinders is in a lifting extended state.

[0014] Beneficial effect: the lifting cylinder pushes the rack up or pulls the rack down, and the gear meshing with the corresponding rack rotates clockwise or counterclockwise, which is equivalent to the lifting cylinder in different initial positions, and can form curved edges in opposite directions upward or downward.

[0015] Furthermore, two groups of bending machines on the same group of bending components are spaced apart by an odd number of grids of the supporting anchor nets.

[0016] Beneficial effect: The odd-numbered intervals enable the two bending machines on the same side of the bending assembly to always move in opposite bending directions, thereby ensuring that the adjacent sides of the formed curved support anchor net are staggered and hooked, thereby ensuring that the entire support anchor net mesh structure is stable and will not easily fall apart.

[0017] Furthermore, a slide bar is fixed on the driving seat in the longitudinal direction, a slider is slidably connected to the slide bar, a positioning mechanism is arranged on the slider, two groups of sliders are arranged at intervals in the longitudinal direction, and the bending machine is arranged on the slider.

[0018] Beneficial effects: By sliding the slider on the slide rod, on the one hand, the spacing between the two bending machines on the bending assembly can be adjusted to adapt to the bending operations of support anchor nets with more grid sizes; on the other hand, the spacing between the two bending machines on the bending assembly is more convenient to adjust, and can be adjusted to the appropriate position of odd grid spacings more quickly.

[0019] Furthermore, the positioning mechanism includes a positioning screw, and a threaded hole is vertically provided on the sliding block, and the positioning screw is threadably connected in the threaded hole.

[0020] Beneficial effect: The distance between the two bending machines on the fixed bending assembly is prevented from sliding and changing position during the bending operation, which affects the bending operation of the support anchor net.

[0021] Furthermore, limit plates are provided at both ends of the sliding rod.

[0022] Beneficial effect: Prevent the slider from slipping off the slide rod and falling off, thereby affecting the bending operation of the support anchor net.

[0023] Furthermore, the driving member is a horizontally arranged transverse cylinder.

[0024] Beneficial effects: The traverse cylinder can drive the driving seat to perform linear translational reciprocating motion, and is easy to install and fix. BRIEF DESCRIPTION OF THE DRAWINGS

The lifting cylinder 7 completes an extension or contraction to drive the rack 6 to move. The rack drives the gear to rotate 180 degrees, and the steel bar head extending into the notch 501 of the gear 5 is bent 180 degrees upward or downward to ensure that the support anchor net 8 is bent. There are two groups of bending machines 1 with opposite bending directions, one group of lifting cylinders 7 is in an initial contracted state, and the other group of lifting cylinders 7 is in a lifting and extending state.
