SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome the defect of above-mentioned technique, provide a coal-winning machine cable clamp drags and moves speed limiting device.
In order to solve the technical problem, the utility model provides a technical scheme is a coal-winning machine cable clamp drags moves overspeed device limiting device: the supporting plate is symmetrically arranged on the fixed plate, a round hole is formed in one end of the supporting plate, screw rods are symmetrically arranged on the middle upper portion of the supporting plate, one ends of the two screw rods extend out of the corresponding round holes and are fixed through nuts, an upward inclined extending portion is arranged at the upper end of the supporting plate, the arc plate is arranged on the extending portion, the backing plate is arranged at the lower end of the arc plate, the backing plate is connected with the arc plate through bolts, a fixing hole is formed in the other end of the supporting plate, one end of the chain is connected with one fixing hole, a hook is arranged at the other end of the chain, and the hook is matched with the other fixing hole;
the upper end of the fixing plate is provided with a notch which is matched with the supporting rod.
As an improvement, the lower end of the fixing plate is symmetrically provided with mounting holes.
As an improvement, the backing plate is made of a flame-retardant belt.
Compared with the prior art, the utility model the advantage lie in: can pass through the mounting hole with the bolt and install the fixed plate on the conveyer cable groove, when needs restriction cable clamp slides like this, just take off the couple of chain from the fixed orifices, the one end that lifts up the bracing piece afterwards makes the backing plate press on the cable clamp, just so can restrict the cable clamp and slide, it is more convenient, the effectual worker safety and production safety of having guaranteed, the emergence of major safety accident has effectively been stopped, can walk around the chain from the bracing piece upper end when not using, hang the couple on the fixed orifices, just so can prevent the malfunction damage bracing piece, can not influence pedestrian's walking, and is small, and the carrier type cable clamp is installed, and convenient for operation, wide application range, safety and reliability.
