Abstract
The utility model provides a kind of safe and reliable and can improve work efficiency and save the suspension device of material.Including pallet, support rod, regulating nut and support plate, one end and the pallet of the support rod fix as one, and the other end of support rod penetrates in the through-hole among support plate after putting on regulating nut, are set in the support plate there are three through-hole.The structure combined using pallet, support rod, regulating nut and support plate, after support plate is inserted in original anchor pole and is spirally connected with anchor pole, only need regulating nut that can play preferable support action, without adding anchor pole again, not only meet the security requirement of supporting, it works at the same time efficiency to greatly improve, also saves a large amount of material.
Description
Technical field
The utility model relates to a kind of protective device of underground coal mine, especially a kind of device of slotting wall supporting.
Background technique
It being required according to underground coal mine one through three prevention management system, surrounding must carry out slotting when constructing air door, confined chamber, by
The supporting condition that original tunnel is destroyed after slotting will lead to the anchor pole failure of support action, empty side phenomenon occurs.In the past
Brake bar, mesh sheet etc. is mostly used to carry out provisional protection, this mode protective capacities is limited, and there is great risk hidden danger.Also it adopts
The investment again of personnel and material, work are increased although this method is reliable with the mode for setting anchor pole again and carrying out supporting
Make inefficient, waste of raw materials is also big, causes that the production cost increases.
Summary of the invention
The purpose of the utility model is to provide a kind of safe and reliable suspension devices that can improve work efficiency and saving material again.
The technical solution of the utility model is: including pallet, support rod, regulating nut and support plate, the support rod
One end fixes as one with pallet, and the other end of support rod penetrates in the through-hole among support plate after putting on regulating nut, described
Through-hole there are three being set in support plate.
In the utility model, the structure combined using pallet, support rod, regulating nut and support plate will support sleeve-board
After entering original anchor pole and being spirally connected with anchor pole, it is only necessary to which regulating nut can play preferable support action, without adding anchor again
Bar not only meets the security requirement of supporting, works at the same time efficiency and greatly improves, and also saves a large amount of material.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram at another visual angle of the utility model.
Fig. 3 is the working state figure after the utility model and rockbolt installation.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, but is not constituted to the utility model
Any restrictions.Shown in Fig. 1 and Fig. 2, the utility model includes pallet 1, support rod 2, regulating nut 3 and support plate 4, the branch
One end of strut 2 fixes as one with pallet 1, and the other end of support rod 2 penetrates among support plate 4 after putting on regulating nut 3
In through-hole, set in the support plate 4 there are three through-hole.
In use, after the completion of coal mine underground air door, confined chamber slotting, shown in Fig. 3, by the top of pallet 1 to needing supporting
In coal wall slot, affixed support rod 2 passes through the through-hole among support plate 4 on pallet 1, then distinguishes the through-hole on 4 both sides of support plate
Two anchor poles 5 being fixed on former lane side are penetrated, screw on nut on two anchor poles 5, and adjust good position.Finally adjust support rod 2
On regulating nut 3 come make pallet 1 hold out against coal wall carry out wall supporting.To further increase supporting effect, expands supporting area, may be used also
Brake bar, mesh sheet etc. are added between pallet 1 and coal wall carries out strengthening supporting.
