Abstract
The utility model relates to a braking device for a waste dump winch, comprising a roller, a reduction box, a shaft coupling and an electromotor. The braking device for the waste dump winch is characterized in that an emergent damper brake is arranged on the shaft coupling, and a handbrake is arranged beside the roller. The braking device for the waste dump winch solves the defect that the braking device for a waste dump hoisting winch of the prior art has short service life due to structural defects and multiple faults, and has the advantages of safe and reliable use, long service life and good braking effect.
Description
Technical field
The utility model is specifically related to a kind of hillock winch brake equipment.
Background technology
The brake equipment of the hillock lifting winch (JT series) that use in the colliery comprises emergency braking lock and rim brake, the emergency braking lock is provided with the cylinder side, rim brake is installed on the coupler between electrical motor and the change speed gear box, because rim brake is arranged on the coupler watt, easily cause the brake rubber block wearing and tearing, the electrical motor operation is obstructed, the not steady phenomenon of operation, secondly can not realize the electric blocking of winch and electrical motor, the emergency braking lock is located at the cylinder side, because contact surface is big, the electro-hydraulic pressure regulator device operating needs is higher, and fault occurs more.
The utility model content
The purpose of this utility model is to solve the brake equipment of prior art hillock lifting winch because the fault of construction fault is many, the defective that service life is short, provide a kind of safe and reliable, deceleration and stopping performance good, long service life hillock winch brake equipment.
The utility model is achieved through the following technical solutions:
Be a kind of hillock winch brake equipment, comprise cylinder, drop-gear box, coupler and electrical motor, it is characterized in that described emergency braking lock is arranged on the coupler, described rim brake is arranged on the cylinder side.
The electric liquid pressure regulating pump of emergency braking lock is connected with electrical motor.
Be provided with weight between the handgrip of rim brake and the link rod.The operation of rim brake is more laborsaving.
The utlity model has safe and reliable, long service life, the advantage of good braking effect.The utility model is located at the emergency braking lock on the coupler, actv. reduces the wearing and tearing of brake rubber block and coupler watt, the electric liquid pressure regulating pump of emergency braking lock is connected with electrical motor, actv. is carried out electric interlocking, better realize emergency braking, rim brake is provided with the cylinder side, then because the increase of the contact surface on brake rubber block and cylinder limit can better realize the deceleration and the parking of winch.
Description of drawings
Accompanying drawing is a structural representation of the present utility model;
As shown in FIG.: 1 cylinder; 2 rim brakes; 3 drop-gear boxs; 4 coupler; 5 emergency braking locks; 6 electrical motors; 7 electric liquid pressure regulating pumps; 8 handgrips; 9 weights; 10 connecting rods.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
Shown in positive: after electric liquid pressure regulating pump 7 is realized electric interlocking with electrical motor 6, be located on the coupler 4, realize by connecting rod that with brake rubber block the unlatching of emergency braking lock 5 is with closed, simultaneously behind the electric interlocking, guarantee only after opening electric liquid pressure regulating pump, could open electrical motor 6, when simultaneously electric liquid pressure regulating pump 7 was out of service, electrical motor 6 was also simultaneously out of service.Be arranged on cylinder 1 side in lock,, realize slowing down winch in moving by the effect of link rod 10 and weight 9.
Claims (3)
1. a hillock winch brake equipment comprises cylinder, drop-gear box, coupler and electrical motor, it is characterized in that described emergency braking lock is arranged on the coupler, and described rim brake is arranged on the cylinder side.
