Abstract
The utility model relates to a folding and unfolding winch for a bottom-lifting car-stopping railing, comprising a motor, a speed reducer, a cylinder and a folding and unfolding cable, wherein the motor is connected with the speed reducer, the cylinder is mounted on the speed reducer, the folding and unfolding cable employs a circular chain, end parts of the circular chain are connected with the cylinder through a pin shaft, and the surface of the cylinder is provided with a slot for containing the circular chain. The circular chain is a hoisting circular chain used by chain-type hoisting apparatuses, and the folding and unfolding angle of the cylinder is smaller than 360 degrees. In the utility model, the circular chain replaces armoured wires, thereby improving traction reliability of the car-stopping railing, reducing maintenance of equipment, and increasing working safety of protection devices.
Description
Technical field
The utility model relates to a kind of mine gradient tunnel derail avoidance technology, particularly a kind of bottom lifting type arrester releasing winch.
Background technology
Bottom lifting buffer stop in the slope rail transport.Promote material by winch traction mine car along the track that lays in the inclined shaft.Promoting and transferring in the process of material, for various reasons, the mine car that may produce lifting breaks away from traction control.Mine car out of control rapidly glides along track, breaks the pit shaft facility, and causes great life to threaten to staff in the following parking lot.Therefore, derail avoidance is a very important safety measure and since from the top, tunnel rise and fall on open the net arrester easily cause scrape online story so, cause personal casualty, therefore, the bottom lifting type arrester that rises and falls under orbital plane is used and is given birth to, and has solved mine car well and has easily scraped the net problem.But in practice process, analyze according to the bottom lifting type arrester of present appearance, the releasing winch of arrester adopts rope traction, and easily broken rope or card rope cause arrester not opened in distraction procedure, and reliability still has problem, and fault rate is higher.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of bottom lifting type arrester releasing winch that improves the arrester functional reliability.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of bottom lifting type arrester releasing winch, comprise motor, reductor, cylinder and folding and unfolding rope, motor is connected with reductor, cylinder is loaded on the reductor, be characterized in: the folding and unfolding rope adopts round-link chain, and the end of round-link chain is connected with cylinder by bearing pin, and the surface of cylinder has the groove that holds round-link chain.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, the lifting round-link chain that round-link chain adopts the chain type weight-lifting equipment to use.
The technical problems to be solved in the utility model can also come to realize that further the folding and unfolding corner of cylinder is less than 360 ° by the following technical programs.
The utility model compared with prior art adopts round-link chain to replace steel rope, has improved the traction reliability of arrester, has reduced the plant maintenance amount, has improved buffer stop safety in the course of the work.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
Fig. 2 is running condition figure of the present utility model.
The specific embodiment
A kind of bottom lifting type arrester releasing winch, comprise motor 1, reductor 2, cylinder 3 and folding and unfolding rope, motor 1 is connected with reductor 2, cylinder 3 is loaded on the reductor 2, the folding and unfolding rope adopts round-link chain, the end of round-link chain 5 is connected with cylinder 3 by bearing pin 4, motor 1 forward and reverse rotation, but make cylinder 3 de-rotation by reductor 2, round-link chain 5 on the cylinder makes arrester open and close, the lifting round-link chain that round-link chain adopts the chain type weight-lifting equipment to use by bearing pin 4 folding and unfoldings, can not produce the fatigue fracture problem of steel rope, stretching resistance at 5～30t for well.The surface of cylinder has the groove that holds round-link chain.Its width should be able to make the facade chain link enter, and 1～10mm is advisable greater than chain link round steel diameter, and gash depth should be not less than chain link round steel diameter.The working diameter of cylinder 3 is finished chain folding and unfolding stroke in the time of should making cylinder folding and unfolding corner less than 360 °.This bottom lifting type arrester is connected with the pivoted arm 7 of bottom lifting type arrester by connector 6 with the round-link chain 5 of releasing winch, and end upshift net 9 is connected with energy disperser 11 by steel rope 10.Releasing winch is by folding and unfolding round-link chain 5, and the pulling pivoted arm makes the end upshift net 9 of arrester open and close.
Claims (3)
1. bottom lifting type arrester releasing winch, comprise motor, reductor, cylinder and folding and unfolding rope, motor is connected with reductor, cylinder is loaded on the reductor, it is characterized in that: the folding and unfolding rope adopts round-link chain, the end of round-link chain is connected with cylinder by bearing pin, and the surface of cylinder has the groove that holds round-link chain.
2. bottom lifting type arrester releasing winch according to claim 1 is characterized in that: the lifting round-link chain that round-link chain adopts the chain type weight-lifting equipment to use.
