Description
Technical field
It is especially a kind of for realizing large torque bidirectional self-locking the present invention relates to a kind of roller Bidirectional non-return device, and energy
It prevents from misplacing with holdback engaging member because of self weight, object weight or horizontal large torque.
Background technique
Shanxi Province is because many places mined-out region occurs in coal mining, in mined-out region actual condition, artificial emergency hand dress
With lower upright time-consuming low efficiency, fail to carry out emergency disposal to mined-out region in time, vertical support post is because naturally
It is easy to run-off the straight and dislocation under the big self weight of feed channel, will cause the personal injury of construction personnel when serious.
Such as Publication No.：A kind of entitled " two-way check of electric point machine roller of CN106286636A
Device " is made of 17 components such as pusher dog, star-wheel, when his self-locking occurs over just motor stalls, is not able to achieve
It is self-locking in real time；Such as Publication No.：" Bidirectional non-return device " disclosed in CN107917154A, the invention can satisfy it is high-speed rotating,
Structure is extremely complex, is simply possible to use in the return-stopping function for realizing high-speed condition, it is self-locking not to be able to achieve speed change；Such as Publication No.：
" Bidirectional non-return device " disclosed in CN201031881 using Beam block structure, check torque is small, and positioning accuracy is poor, uses the longevity
It orders short；For another example Publication No.：" electric traction rope Bidirectional non-return device " disclosed in CN204661221U, by electromagnet obtain it is electric with
Power loss control is locked, and safe life is short, and can only realize and unilaterally lock, and limitation is big.
In addition, existing holdback is mostly belt holdback, there is a problem of many such as conventional holdbacks in work
It can only all guarantee unidirectional check, be loosened at once once torque changes direction, and conventional holdback cannot be determined at any time
Point location, therefore still there is inconvenience in construction.
Above-mentioned four classes Bidirectional non-return device not can solve natural gas line settlement issues, therefore, design a kind of double in realization
Under the premise of self-locking, it can not occur to misplace clockwise or counterclockwise under large torque, and any work can be navigated to
The roller Bidirectional non-return device of the position needed be very timely and there is an urgent need to.
Summary of the invention
The present invention is based on the deficiencies in the prior art, a kind of roller Bidirectional non-return device are provided, to the oil gas of mined-out region
Conveyance conduit or other large size hanging engineerings are positioned and are supported, de- to reduce equipment caused by pipe-line or weight
It falls and slides, prevent engineering accident.
To achieve the goals above, the technical solution used in the present invention is as follows：
A kind of roller Bidirectional non-return device, including holdback axis, holdback shell box cover and holdback shell；It is characterized in that：
