Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment in the utility model is described in further detail.
As shown in Figure 1, the gas brake removing device that the elevator traction machine that the utility model relates to uses, include the brake arm 2 being arranged on brake wheel 1 both sides, described brake arm 2 is respectively arranged with the band-type brake block 3 abutted against with brake wheel 1, one end of described brake arm 2 is hinged on support 4 respectively, connecting rod 5 is fixed on support 4, retarding spring 6 is enclosed within connecting rod 5 respectively, one end of retarding spring 6 one end and connecting rod 5 offsets, retarding spring 6 other end and brake arm 2 other end abut against, comprise gas storehouse 7, storage tank 8, gas piping 9, air film 10, push rod 11 and control device of air, described gas storehouse 7 is arranged on the centre of two brake arm 2, described air film 10 is arranged on both sides in described gas storehouse 7, gas storehouse 18 before middle gas storehouse 17 and film will be divided in gas storehouse 7, one end of described push rod 11 is connected on air film 10, the other end of push rod 11 is connected with brake arm 2 upper end through gas storehouse 7 outer wall, the middle gas storehouse 17 in described gas storehouse 7 is provided with middle inlet end 12 and middle outlet side 13, before the film in described gas storehouse 7, gas storehouse 18 is provided with inlet end 14 before film, the middle inlet end 12 in described gas storehouse 7 is connected with storage tank 8 respectively by gas piping 9 with inlet end before film 14, described middle outlet side 13 is directly connected with air, described control device of air is separately positioned on corresponding gas piping 9.
Inwall both sides, described gas storehouse 7 are respectively arranged with push rod pipe box 16, and described push rod 11 is contained in push rod pipe box 16.
Control device of air in the utility model to be made up of several electric control reversing valve and electrically-controlled valve, electric control reversing valve and electrically-controlled valve are separately positioned on corresponding gas piping 9, controlled by the break-make of controller to the switching commutation of electric control reversing valve and electrically-controlled valve, reach braking and the brake off of push rod 11 pairs of band-type brakes, described control device of air is prior art, and in this not go into detail.
Storage tank 8 in the utility model is energy-storage travelling wave tube, and when in storage tank 8 during insufficient pressure, automatically can start air compressor be that storage tank supplements.
It is outer in quiescence that the utility model works as elevator, brake wheel 1 both sides are extruded to centre by band-type brake block 3, brake wheel 1 can not be rotated by locking, and keep braking mode, now electric control reversing valve commutation blocks middle inlet end 12, opens middle outlet side 13 simultaneously, be positioned at inlet end 14 air inlet before the electric control reversing valve commutation barrier film before film on inlet end 14, two brake arm inwardly extrude under the effect of retarding spring 6, reach the work of pressurize braking with locked wheels wheel; Operationally, braking mode needs to remove, outlet side 13 in the middle of electric control reversing valve commutation blocks, open middle inlet end 12, in the middle gas storehouse 17 in gas storehouse 7, pressure promotion air film 10 drives push rod 11 to release to both sides, brake arm 2 is opened to both sides, makes band-type brake block 3 no longer hold brake wheel 1 tightly, brake wheel 1 can rotate freely, and 1 braking mode reaching brake wheel is removed; When braking mode needs to recover, as long as above-mentioned electric control reversing valve is carried out switch operation, can braking operation be completed, not be described in detail at this.
The utility model at work, when to occur in the middle of unforeseen circumstances that two electric control reversing valves of inlet end 12 have a sudden failure, another electric control reversing valve still can normally work, block middle inlet end 12, open middle outlet side 13 simultaneously, two brake arm inwardly extrude under the pressure effect of retarding spring 6, brake wheel 1 both sides, by band-type brake block 3 locking, reach braking effect.
The utility model at work, when there is unforeseen circumstances accidental movement of elevator cage, velocity limiter place spreads out of overspeed signal, the electric control reversing valve being now positioned at middle gas storehouse 17 commutates rapidly and blocks middle inlet end 12, opens middle outlet side 13 simultaneously, before being positioned at film, the electrically-controlled valve in gas storehouse 18 opens inlet end 14 before film, brake rapidly under air pressure and push rod 11 double action, prevent accidental movement.
When the utility model at work, when there is unforeseen circumstances retarding spring 6 fracture failure, when brake wheel 1 needs to recover braking, be positioned at the electric control reversing valve work on middle gas storehouse 17, open middle outlet side 13, before before being positioned at film, the electrically-controlled valve in gas storehouse 18 opens film, inlet end 14 promotes air film 10 to middle crimp, and push rod 11 pulls brake arm 2 to extrude to centre, band-type brake block 3 holds brake wheel 1 tightly, thus completes complete braking operation under retarding spring 6 breaks down.
In the utility model, owing to having certain interval between push rod 11 and push rod tube 16, therefore gas storehouse 18 is only provided with inlet end 14 before film before film, with simplified design scheme.
The above, be only better possible embodiments of the present utility model, and be not used to limit scope of the present utility model.
