Abstract
The invention relates to a two-side manual releasing device which comprises a pawl, a driving lever, a first releasing box body and a second releasing box body. The first releasing box body and the second releasing box body are each provided with a driving mechanism. The back of the pawl is provided with a hook head. The driving mechanism inside the first releasing box body presses the tail of the pawl downwards to enable the pawl to rotate, and releasing is achieved; the driving mechanism inside the second releasing box body presses the tail of the driving lever downwards, so that the hook head is driven to enable the pawl to rotate, and releasing is achieved. Compared with a traditional device, one releasing mechanism is additionally arranged, and the pawl is indirectly driven to rotate through cooperation between the driving lever and the hook head arranged on the back of the pawl, so that releasing is achieved; the two releasing mechanisms do not interfere with or affect each other, and can independently operate. Manual releasing can be achieved on parking cylinders on the two sides of a vehicle.

Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
As shown in Figure 1, the present embodiment bilateral hand relieving device, has fixedly to park on cylinder cap and be positioned at first of pawl seat both sides and alleviates casing 12 and the second alleviation casing 5; First, second alleviates the both sides that its handle of inhaul cable assembly 1(lays respectively at vehicle); Be hinged on the ratchet 13 parked on cylinder cap, as shown in Figure 2, this ratchet 13 has the sour jujube tongue 15 rotated for latch ratchet seat matched with pawl seat ratchet, and is positioned at the ratchet afterbody 16 of described sour jujube tongue 15 offside, and is positioned at the eave tile 17 of ratchet 13 back near sour jujube tongue 15 side.First alleviation inhaul cable assembly 20 makes the first driver train action in the first alleviation casing 12, presses down ratchet afterbody 16 and makes ratchet 13 rotate clockwise certain angle by Fig. 1, sour jujube tongue 15 and pawl seat is broken off relations, thus realizes manual unlocking.Be positioned at second of left side and alleviate the second driver train of casing 5 then by pressing down the block diagram of driving lever afterbody 20(driving lever 6 see Fig. 3), it is made to rotate by anticlockwise direction in Fig. 1, thus by the eave tile 17 that driving lever head 18 stirs ratchet 13 back, ratchet 13 is rotated by clockwise direction in Fig. 1, realize the manual unlocking of opposite side.Accordingly, this side manual unlocking realizes propulsive effort by the second pulling alleviating inhaul cable assembly 1.In order to realize the reset function of driving lever 6, the bearing pin 10 of driving lever 6 is equipped with torsion spring 11, torsion spring 11 one end props up driving lever 6, and the other end props up parks cylinder cap.
As shown in Figure 1, the the second driver train composition being positioned at the second alleviation casing 5 comprises: hand alleviates cover 14, first end inserts the hollow tube 3 that described hand alleviates cover 14, be enclosed within the actuator 7 for pressing down driving lever afterbody 20 of hollow tube 3 second side, be enclosed within two ends on described hollow tube 3 and prop up the retracing spring 4 that hand alleviates cover 14 and actuator 7 respectively, prop up the fluting back-up ring 9 of hollow tube 3 second end, be positioned at hand alleviate the anti-wearing liner 2 of cover 14 bottom and be positioned at the dust-proof plug 8 of described anti-wearing liner 2 offside, second head of steel wire rope alleviating inhaul cable assembly 1 alleviates cover 14 through hand successively, hollow tube 3 is connected with fluting back-up ring 9.The structure that first driver train is identical with the second driver train, the present embodiment no longer describes in detail.
Steel cord ends termination in second alleviation inhaul cable assembly 1 is by fluting back-up ring 9 pressing actuator 7, and actuator 7 rotates by promoting the indirect ratchet 13 that drives of driving lever afterbody 20, realizes parking brake and alleviates.
When train is parked under cylinder is in and puts braking mode without always to becalm, operator drives ratchet 13 by the dynamic drag-line of alleviating of any layback in train both sides, and the ratchet autobiography restriction of parking in cylinder is cancelled, and realizes parking brake and alleviate under the effect of parking spring.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
