Abstract
A kind of stay-bolt for embracing pricker device for deep hole trolley, including bolt body and bolt holder, the bolt holder is square cylinder, the width of bolt holder is twice of the bolt body external thread diameter, the length of bolt holder and the length of bolt body are adapted, and bolt holder is axially arranged with through-hole.Pass through the implementation of the utility model, when carrying out stay-bolt replacement, bolt holder need to be only placed on bolt body, it can be replaced, without tearing the fixed bracket of oil cylinder and oil cylinder open, the replacement operation of all stay-bolts can be completed half an hour in one operator, it is time saving and energy saving, equipment effect is substantially increased, the labor intensity of maintenance replacement is reduced, has got the time for production, simultaneously, bolt holder has used rectangular contour structures, is conducive to keep stability when being replaced, and avoids the generation of safety accident.
Description
Technical field
The utility model relates to a kind of stay-bolts that pricker device is embraced for deep hole trolley.
Background technique
Currently, deep hole trolley is the widely applied equipment in mine, and now widely used DL331 deep hole trolley
Embrace pricker device, be made of oil cylinder, the fixed bracket of oil cylinder, 4 stay-bolts, and entirely embrace pricker device by multiple stay-bolts respectively
Cylinder bracket is fixed in trolley rack.Due to using the time long or operative employee's improper use, stay-bolt fracture is often resulted in,
When replacing stay-bolt, it is necessary to which 4 stay-bolts could be replaced by splitting out the fixed bracket in armful pricker device one end and oil cylinder.It installs thereon
Stay-bolt be an entirety, movable disassembly can not be carried out, cause to replace intricate operation, the time is long.Carry out primary replacement extremely
It needs two operators time-consuming 2 hours or more that more changing jobs for all bolts could be completed less, it is time-consuming and laborious, in addition, maintenance
The occupied time is replaced, strong influence is also resulted in manufacturing schedule, accordingly, it is desirable to provide it is a kind of easy to disassemble, it can be more
Transsexual good stay-bolt.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of stay-bolt for embracing pricker device for deep hole trolley.
The utility model is achieved by the following technical programs.
A kind of stay-bolt for embracing pricker device for deep hole trolley provided by the utility model, including bolt body and bolt branch
Frame, the bolt holder are square cylinder, and the width of bolt holder is twice of the bolt body external thread diameter, bolt
The length of bracket and the length of bolt body are adapted, and bolt holder is axially arranged with through-hole.
Further, the big 1-2mm of external thread diameter of the aperture ratio bolt body 1 of the through-hole.
Further, the length of the bolt holder is the half of bolt body length to 2/3rds.
Further, the central axes of the through-hole are overlapped with the central axes of bolt body.
Further, the bolt holder is made using No. 45 steel.
Further, before being installed and used, plastic-spraying processing is carried out to the outer surface of the bolt holder.
Further, the outer surface of the bolt holder is equipped with the carburized layer of 1-2mm.
The utility model has the beneficial effects that: by the implementation of the utility model, when carrying out stay-bolt replacement, only
Bolt holder need to be placed on bolt body, can be replaced, without tearing the fixed bracket of oil cylinder and oil cylinder, an operator open
The replacement operation of all stay-bolts can be completed in half an hour, time saving and energy saving, substantially increases equipment effect, reduces dimension
The labor intensity of replacement is repaired, has been got the time for production, meanwhile, bolt holder has used rectangular contour structures, is conducive to
Stability is kept when being replaced, and avoids the generation of safety accident.
Detailed description of the invention
Fig. 1 is the mounting connection structure schematic diagram of the utility model；
Fig. 2 is the bolt holder structural schematic diagram of the utility model；
Fig. 3 is the bolt holder top view of the utility model；
In figure: 1- bolt body, 2- bolt holder, 21- through-hole.
Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figures 1 and 2, a kind of stay-bolt for embracing pricker device for deep hole trolley, one kind embracing pricker for deep hole trolley
The stay-bolt of device, it is characterised in that: including bolt body 1 and bolt holder 2, the bolt holder 2 is square cylinder, spiral shell
The width of bolt bracket 2 is twice of 1 external thread diameter of bolt body, the length of bolt holder 2 and the length of bolt body 1
It is adapted, bolt holder 2 is axially arranged with through-hole 21.When carrying out stay-bolt replacement, by 2 sets of bolt holder in bolt body
On 1, it can be replaced.
Further, the big 1-2mm of external thread diameter of the aperture ratio bolt body 1 of the through-hole 21.
Further, the length of the bolt holder 2 is the half of 1 length of bolt body to 2/3rds.
Further, the central axes of the through-hole 21 are overlapped with the central axes of bolt body 1.
Further, the bolt holder 2 is made using No. 45 steel.
Further, before being installed and used, plastic-spraying processing is carried out to the outer surface of the bolt holder 2.
Further, the outer surface of the bolt holder 2 is equipped with the carburized layer of 1-2mm.
By the implementation of the utility model, when carrying out stay-bolt replacement, only bolt holder need to be placed on bolt body
On, it can be replaced, all pull rods can be completed half an hour without tearing the fixed bracket of oil cylinder and oil cylinder, an operator open
The replacement operation of bolt, it is time saving and energy saving, equipment effect is substantially increased, the labor intensity of maintenance replacement is reduced, for production
It has got the time, meanwhile, bolt holder has used rectangular contour structures, is conducive to keep stability when being replaced, keep away
Exempt from the generation of safety accident.
