Abstract
The utility model discloses a hinge spring cylinder brake, comprising a spring clamping cylinder which is provided with a cylinder body which is internally provided with a piston; the piston is connected with a piston-rod sleeved with a spring; the cylinder body is provided with a gas and liquid inlet; the piston-rod of the spring clamping cylinder is connected with a lever mechanism which is connected with a braking belt mechanism. The utility model is reasonable in structure, and can ensure the pneumatic (or hydraulic) hinge to be used safely. Besides, the utility model can ensure equipments to brake in time when the gas sources (or liquid sources) stop suddenly.
Description
Technical field:
The utility model relates to and a kind ofly is used to promote or hoisting mechanism is the drg of air pressure (or hydraulic pressure) winch of characteristics.
Background technology: pneumatic (or hydraulic pressure) winch is mainly used in the mining site lifting means, its brake mode present stage mainly is service brake or parking brake, be artificial control, its scene uses that often accidentalia is very big, interrupt as source of the gas or liquid source suddenly, unsettled equipment often can not get artificial timely brake and clashes into damage, even causes casualties.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and can guarantee the winch spring cylinder drg that winch is safe in utilization.
Technical solution of the present utility model is:
A kind of winch spring cylinder drg, its feature: the spring clamping cylinder is arranged, and the spring clamping cylinder has cylinder body, dress piston in the cylinder body, piston connects piston rod, upper cover of piston rod shock mount, offer the gas-liquid through hole on the cylinder body, the piston rod of spring clamping cylinder connects leverage, and leverage connects brake band mechanism.
Brake band mechanism comprises brake band, the inboard dress brake of brake band shell.
The utility model is rational in infrastructure, can guarantee that pneumatic (or hydraulic pressure) winch is safe in utilization, when interrupting suddenly, equipment is in time braked at source of the gas (or liquid source).
Description of drawings:
Accompanying drawing is the configuration diagram of an embodiment of the utility model.
The specific embodiment:
A kind of winch spring cylinder drg, the spring clamping cylinder is arranged, the spring clamping cylinder has cylinder body 1, dress piston 2 in the cylinder body 1, piston 2 connects piston rod 3, and pocketed springs 4 on the piston rod 3, offer gas (or liquid) through hole 5 on the cylinder body 1, the piston rod 3 of spring clamping cylinder connects leverage 6, and leverage 6 connects brake band 7, brake band 7 inboard dress brake shells 8.
During use, shell 8 suits that will brake are connected in outside the winch drum, through hole 5 is communicated with source of the gas (or liquid source), when gas motor (or liquid supplying device) is worked, the piston 2 of spring clamping cylinder, piston rod 3 overcome the elastic force of spring 4, promote leverage, make brake band 7 break away from brake shell 8, winch drum normal operation; When source of the gas (or liquid source) interrupted, compression spring 4 promoted piston rod 3 motions, causes the winch drum braking.
Claims (2)
1, a kind of winch spring cylinder drg, it is characterized in that: the spring clamping cylinder is arranged, the spring clamping cylinder has cylinder body, dress piston in the cylinder body, piston connects piston rod, and the upper cover of piston rod shock mount is offered the gas-liquid through hole on the cylinder body, the piston rod of spring clamping cylinder connects leverage, and leverage connects brake band mechanism.
2, winch spring cylinder drg according to claim 1, it is characterized in that: brake band mechanism comprises brake band, the inboard dress brake of brake band shell.
