Description
Technical field
The present invention relates to cable protection equipment technology field, specifically a kind of flitting service cable protection dress
Put.
Background technology
Coal-winning machine service cable is the pith for ensureing coal-winning machine normal work, and flitting is past back and forth in working face
Return to work during work, service cable is mainly protected and dragged by the cable handler of flitting.But cable handler exists
Bad environments during work, the sometimes protection to cable can fail, and cause service cable under tension, in order that cable not tension
Power, working site is held generally by rope at the pin-and-hole of first cable clamp, after a particular period of use
(generally or so two weeks), in order to ensure the security of rope, workman can re-replace rope, but it is one to change
Comparatively laborious process.And if the time is too long, the cable surplus in cable elbow can reduce, the bending radius mistake of cable
It is small, it is possible to make it that cable receives the risk of bending damage, this is accomplished by taking out cable from cable handler, then weighed again
Newly penetrate so that cable elbow there are enough cable length surpluses, it is ensured that larger bending radius.Such time and effort consuming, sternly
The operating efficiency of working face is have impact on again, adds the labor intensity of workman, and bring hidden danger to the safety of cable.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of reasonable in design, lower-cost, Neng Goushi
Now to the device of cable protection, i.e., a kind of flitting service cable protection device.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of flitting service cable protection device, including microswitch, upper lid, lower cover, safety pin, bolt and control
Ring processed.The upper portion of lid is provided with the middle part of square groove, the square groove and is provided with one number service hole, and the upper portion of lid is additionally provided with door, and
The door be located at square groove above, it is described on be covered with No. two through holes, the upper lid both sides end face is equipped with an annular groove, described
Provided with a semicircle groove in the middle part of upper lid, described No. one semicircle groove is provided with No. three through holes and No. four through holes, described No. one
