Description
Technical Field
The utility model belongs to strut the field, especially relate to folding transportation problem in the mine support metal protecting wire net transportation.
Background
The required material kind of each working face in colliery is more, and the consumption is great, often adopts the belt to transport various materials to improve conveying efficiency, guarantee that the required material of each working face is supplied with. In the supporting material, the reinforcing steel bar protecting net is used in a large number, and 3 workers are required to fold and flatten the reinforcing steel bar protecting net with the width of 1m to be arranged on a belt for transportation in order to meet the loading and unloading requirements of belt transportation. The metal protecting net folding mode brings great workload to workers, so that the production efficiency is low, and the manual net folding is easily scratched by reinforcing steel bars at the end parts of the protecting net during operation, thereby bringing certain potential safety hazards to the workers. We therefore propose a folding device for a metal protecting mesh for mine support.
Disclosure of Invention
A primary object of the utility model is to provide a folding device for mine support's metal protecting wire net can effectively solve the problem in the background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a folding device for a metal protecting net for mine support comprises a force application rod, a force application baffle, a rotary fixing device, a protecting net folding base and the like.
The force application rod is a hollow steel pipe, the length of the force application rod is 500mm, one end of the force application rod is provided with a force application rod handle, and the inside of the steel pipe at the other end is provided with a thread connected with the rotary fixing device.
The force application baffle is fixed on the force application rod, is made of a plastic plate and has the size of 200 × 300 × 20 mm.
The rotary fixing device is divided into two parts, one part is a solid steel bar connected with one end of the force application rod through threads, a screw rod welded with the solid steel bar and a nut matched with the screw rod for use, and the other part is a nut welded on the protective net folding base.
The protective net folding base comprises channel steel, steel pipes and the like, wherein the two channel steel are 4000 mm; a nut of the rotary fixing device is welded in the center of the large-size channel steel 500mm away from one end, a positioning hook is welded in the position 900mm away from the other end of the channel steel 500mm away from the end, and a small hole is drilled in the center of the other end of the channel steel 500mm away from the end; drilling 6 small holes with the same aperture as that of the large channel steel at the position 500mm away from the center of one end of the small channel steel at intervals of 500mm, arranging a limit baffle at the position 500mm away from the other end of the small channel steel, fixedly connecting the large channel steel and the small channel steel through screw nuts, and adjusting the folding length as required; the steel pipe and the channel steel are welded to form a base support.
Compared with the prior art, the utility model have following advantage: the utility model provides an application of a folding device for mine support's metal protecting wire net, through the lever principle of stress application pole, only needs alone to operate, reducible constructor quantity, and can ensure workman's safety. The device can be used at any net folding place, and when the device is used, the middle part of the reinforcing mesh is clamped into the positioning hook, and the reinforcing mesh is folded by using the stressing rod. The device can operate in a flexible way and can ensure the safety of constructors, is convenient to operate, is quick and simple to fold the net, has lower manufacturing cost, can improve the working efficiency, creates larger input-output ratio, and has good popularization value.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
An embodiment of the invention is further described below with reference to the accompanying drawings:
a folding device for a metal protecting net for mine support comprises a force application rod 2, a force application baffle 3, a rotary fixing device 4, a protecting net folding base 6 and the like.
The force application rod 2 is a hollow steel pipe with the length of 500mm, one end of the force application rod is provided with a force application rod handle 1, and the inside of the steel pipe at the other end is provided with a thread connected with the rotary fixing device.
The force application baffle 3 is fixed on the force application rod 2, is made of a plastic plate and has the size of 200 × 300 × 20 mm.
The rotary fixing device 4 is divided into two parts, one part is a solid steel bar connected with one end of the force application rod through threads, a screw rod welded with the solid steel bar and a nut used with the screw rod in a matched mode, and the other part is a nut welded on the protective net folding base 6.
The protective net folding base 6 comprises channel steel, steel pipes and the like, wherein the two channel steel are 4000 mm; a nut of the rotary fixing device is welded in the center of the large-size channel steel 500mm away from one end, a positioning hook 5 is welded in the position 900mm away from the other end of the channel steel 500mm away from the end, and a small hole is drilled in the center of the other end of the channel steel 500mm away from the end; drilling 6 small holes with the same aperture as that of the large channel steel at the position 500mm away from the center of one end of the small channel steel at intervals of 500mm, arranging a limit baffle 7 at the position 500mm away from the other end of the small channel steel, fixedly connecting the large channel steel and the small channel steel through screw nuts, and adjusting the folding length as required; the steel pipe and the channel steel are welded to form a base support.
