Abstract
The utility model relates to the technical field of internal combustion engine braking systems and particularly relates to a double-pulley hand brake device, which comprises a crank, a gear case, a screw, a pulley, a cross bar, a shifting fork assembling mechanism, a movable pulley, a steel wire rope 1 and a steel wire rope 2. The crank is connected with the gear case. The lower part of the gear case is provided with the screw. Through rotating the crank, the steel wire rope 1 wound on the screw at the lower part of the gear case is driven to move upwards. The movement direction of the above steel wire rope is changed by means of the pulley and then the cross bar is tensioned. Then the shifting fork assembling mechanism loaded on a unit brake can be pulled to move through the steel wire rope 2. The movable pulley is arranged in front of the cross bar. The cross bar is tensioned by the screw via the steel wire rope 1, the pulley and the movable pulley. One end of the steel wire rope 1 is fixed onto the screw, while the other end of the steel wire rope 1 is wound around the pulley and the movable pulley to be fixed onto a fixing base arranged below the front end of a locomotive frame. According to the technical scheme of the utility model, due to the adoption of the device, the parking capacity of a locomotive is effectively improved, so that the locomotive with the above device can be safely parked on a ramp of a large gradient. Therefore, the device satisfies the parking requirements of locomotives in different routes.
Description
Technical field
The utility model relates to combustion engine braking systems technology field, especially a kind of sister block hand brake device.
Background technology
Hand brake device is an important component part of locomotive braking system, when the locomotive air brake equipment does not have pressure air, the driver manually shakes the steel rope upward movement on the screw rod of hand braking crank driven gear case below, steel rope changes direction by pulley, and with the cross bar tension, more translateral steel rope pulls the pulling fork assembling machine structure that is contained on unit brake, the pulling fork assembling machine structure is stirred the unit brake lever, thereby power is passed on lever, produce brake action, prevent the locomotive runaway.As shown in Figure 1.
Former hand brake device is the single-sheaved block structure, and the power that hand braking crank is implemented directly is delivered on drg by pulley, and when locomotive was parked on the larger ramp of the gradient, locomotive, because of the too little runaway that causes of parking brake power, can not meet the requirement of parking of locomotive.
The utility model content
In order to overcome the deficiency of existing technology, the utility model provides a kind of sister block hand brake device.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of sister block hand brake device, comprise crank, gear case, screw rod, pulley, cross bar, fork assemble mechanism, movable pulley, steel rope one and steel rope two, crank is connected with gear case, screw rod is equipped with in the gear case below, cross bar is connected with the fork assemble mechanism by steel rope two, be provided with another movable pulley before described cross bar, screw rod is by steel rope one, pulley and movable pulley tension cross bar.
According to another embodiment of the present utility model, comprise further that described steel rope is held one by one to be fixed on screw rod, the other end walks around pulley, pass on the permanent seat that movable pulley is fixed in locomotive frame's front end below.
The beneficial effects of the utility model are, the sister block hand brake device has effectively increased locomotive and parked ability, and dress can safety be parked with the locomotive of this device on the larger ramp of the gradient, meet locomotive and park requirement on different circuits.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is original technology single-sheaved block hand brake device structural representation;
Fig. 2 is the utility model sister block hand brake device structural representation;
In figure 1, crank, 2, gear case, 3, screw rod, 4, pulley, 5, cross bar, 6, the fork assemble mechanism, 7, movable pulley, 8, steel rope one, 9, steel rope two.
The specific embodiment
Fig. 2 is structural representation of the present utility model, and a kind of sister block hand brake device comprises crank 1, gear case 2, screw rod 3, pulley 4, cross bar 5, fork assemble mechanism 6, movable pulley 7, steel rope 1 and steel rope 29.Crank 1 is connected with gear case 2, screw rod 3 is equipped with in gear case 2 belows, shake steel rope one 8 upward movements on the screw rod 3 of hand braking crank 1 driven gear case 2 belows, change the steel rope direction by pulley 4, with cross bar 5 tensions, then pull the pulling fork assembling machine structure 6 that is contained on unit brake through steel rope 29.Be provided with a movable pulley 7 before described cross bar 5, screw rod 3 is by steel rope 1, pulley 4 and movable pulley 7 tension cross bars 5, described steel rope one 8 one ends are fixed on screw rod 3, and the other end walks around pulley 4, pass on the permanent seat that movable pulley 7 is fixed in locomotive frame's front end below.
The utility model increases a movable pulley at the cross bar front end, is delivered on drg after by movable pulley, the power on steel rope being amplified twice, has increased locomotive and has parked the power ability, and dress can safety be parked with the locomotive of this device on the larger ramp of the gradient.
The utility model sister block hand brake device has the characteristics such as safe, novel, reliable, is worthy to be popularized.
In sum, it is only preferred embodiment of the present utility model, not be used for limiting the scope that the utility model is implemented, all equalizations of according to the described shape of the utility model claim scope, structure, feature, doing change and modify, and all should be included in claim scope of the present utility model.
