Abstract
The utility model relates to a spring stopping brake for rolling stock, which is mainly used for the still parking of rolling stock and performs the function of stopping rolling stock by handbrake. The utility model uses spring action and amplifies the action force which acts on a wheel tread or a brake disc to stop a car. The utility model uses a special structure which comprises a regulating screw rod, a regulating nut and a locked ratchet wheel to realize the braking and the high-speed alleviation of the spring stopping brake. The brake has the advantages that the regulating screw rod, the regulating nut and the locked ratchet wheel are locked firmly, the high-speed alleviation is quick, the action is accurate and flexible, and the output force of the spring is large.
Description
The utility model relates to Vehicular brake device, is specially adapted to the static parking of railway locomotive, vehicle and motor train unit.
At present, the static parking of China's locomotive, vehicle and motor train unit is to rely on traditional hand brake device substantially, utilizes manpower, carries out static parking by handwheel, chain and brake beam, and this device driving efficiency is low, brake shoe pressure is little.Domestic some unit is developing spring parking device now, entrucking utilization scope is less, its structure is the lever coordinated type, only can with brake cylinder with lever amplification or the supporting use of brake unit, need stop when major defect is hand relieving can alleviate in 15 seconds and finish.
The purpose of this utility model is to overcome above-mentioned shortcoming, a kind of spring parking device is provided, can with the supporting use of brake unit, rely on the spring force of spring parking device, by the enlargement ratio of brake unit, masterpiece is used on wheel or the brake disc, reach static parking, and have quick mitigation, be beneficial to shunting service.
The technical solution of the utility model is to realize like this, a kind of spring parking device that is used for rolling stock, can constitute the tread brake unit of band spring parking device with the supporting use of brake unit, comprise ratchet, pawl seat, leading screw, nut, collude shellfish, outer cover and spring, compositions such as bearing, its special character is that the spring in the cover body acts on by bearing and colludes on the shellfish, colluding shellfish is pressed on the adjustment nut, the outside of nut has three guide grooves, the locking ratchet that be installed in this nut on corresponding with it is provided with three keys, three guide grooves and key are that 120 ° of symmetries are placed, its shape is special, the action non-resistance, its key is inserted in the guide groove of adjustment nut, and adjustment nut is screwed in whole the adjustment on the leading screw, and the handle that has ratchet that the rotation of nut and leading screw is inserted on the ratchet is controlled.
The utility model advantage compared with prior art be this spring parking device can with the supporting use of brake unit, the braking that the special connecting mode realization spring parking device of leading screw, adjustment nut and locking ratchet is adjusted in dependence reaches alleviation fast, and utilization is accurate, flexible, the spring power output is big and guarantee that locking is firm, can satisfy operating needs.
Now describe the utility model most preferred embodiment in conjunction with the accompanying drawings in detail.
Fig. 1 is the spring parking device structural representation
Fig. 2 is for connecting scheme drawing between ratchet, leading screw, the nut in the spring parking device
Fig. 3 is an A-A section-drawing among Fig. 2
Fig. 4 is the structural representation of the tread brake unit of XFD-2 type band spring parking device
Among the figure: 1, cover body; 2, brake unit; 3, the whole leading screw of adjusting; 4, adjustment nut; 5, locking ratchet; 6,7, collude shellfish; 8, the alleviation handle that has ratchet; 9, bearing; 10,11, spring; 12, pawl seat; 13, guide groove; 14, key.
A kind of spring stop device that is used for rolling stock as shown in Figure 1, 2, 3.It can with the tread brake unit of the supporting formation band of brake unit spring parking device as shown in Figure 4.The spring stop device includes locking ratchet 5, pawl seat 12, the whole leading screw 3 of adjusting, and adjustment nut 4 colludes shellfish 6, outer cover 1, spring 10,11, bearing 9 is alleviated handle 8 compositions such as grade.Spring 10,11 in the cover body 1 acts on by bearing 9 and colludes on the shellfish 6, colluding shellfish 6 is pressed on the adjustment nut 4, the outside of nut 4 has the guide groove 13 of three 120 ° of symmetries, the locking ratchet 5 that be installed in this nut 4 on corresponding with it is provided with three keys 14, its key 14 is inserted in the guide groove 13 of adjustment nut 4, adjustment nut 4 is screwed in whole the adjustment on the leading screw 3, and the rotation of nut 4 and leading screw 3 is inserted in the control of the handle that has ratchet 8 on the ratchet 5.When the need hand relieving, the pulling hand is alleviated handle 8, frees locking ratchet 5, and whole adjustment leading screw 3 and adjustment nut 4 rotate, and whole the adjustment on the leading screw 3 moved, and brake action is alleviated.This spring parking device can with the tread brake unit of the supporting formation of brake unit XFD-2 type band spring parking device as shown in Figure 4: comprise spring parking device 1 and tread brake unit 2 two parts.Comprise whole leading screw 3, adjustment nut 4 and the locking ratchet 5 transferred in the spring parking device 1.When this spring parking device colludes shellfish 6 belows when charging into total wind, collude shellfish 6 and move up, when discharging total wind, the whole leading screw 3 of adjusting moves down, and shellfish 7, apply brake effect are colluded in the braking that promotes tread brake unit 2.After colluding shellfish 6 downsides and feeding total wind pressure, parking brake colludes on the shellfish 6 and moves, and compression spring 10,11, parking brake are in alleviates the position.After rolling stock stops, discharge total wind pressure, parking brake colludes shellfish 6 and moves down under spring 10,11 effects, because leading screw 3 and adjustment nut 4 and ratchet 5 lockings, make and adjust leading screw 3 and move down, will promote the brake unit amplification and collude shellfish and move, impose brake action.
Claims (2)
1, a kind of spring parking device that is used for rolling stock, can with the supporting use of brake unit, constitute the tread brake unit of band spring parking device, comprise ratchet, pawl seat, leading screw, nut, collude shellfish, outer cover and spring, compositions such as bearing, it is characterized in that: the spring in the cover body acts on by bearing and colludes on the shellfish, colluding shellfish is pressed on the adjustment nut, the outside of nut has three guide grooves, the locking ratchet that be installed in this nut on corresponding with it is provided with three keys, its key is inserted in the guide groove of adjustment nut, adjust mother and be screwed in whole the adjustment on the leading screw, the handle that has ratchet that the rotation of nut is inserted on the ratchet is controlled.
