As further optimization of the present utility model, described left connecting rod outer end is provided with one section of left screw rod of step, and described plunger rod outer end is provided with one section of right screw rod of step, and described two clamping handles are fixed on left screw rod and right screw rod by nut respectively.
The utility model has the following advantages compared to existing technology:
The brake gear of a kind of railroad hauling car that the utility model provides, changes original one-way brake into bilateral braking, and clamping handle is bilateral to be held tightly, and friction lining is braked from the bilateral of vehicle bridge, and braking effect is good; It is controlled by hydraulic oil simultaneously, safe and reliable; Only need the foot-treadle just can attainment brake hydraulic pressure, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented take technical solutions of the utility model under prerequisite; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Referring to Fig. 1, the brake gear of a kind of railroad hauling car that the utility model provides, comprise frame 1 and the wheel 2 of being located at frame 1 below, in frame 1, directly over wheel 2, be provided with oil cylinder 3, oil cylinder 3 top left right-hand members are respectively equipped with left oil port 31 and right oil port 32, left oil port 31 and the right oil port 32 of oil cylinder 3 are connected to valve and pump successively by oil pipe respectively, and valve is controlled by stretcher; Oil cylinder 3 left ends are fixedly connected with left connecting rod 4, and left connecting rod 4 outer ends are provided with one section of left screw rod 41 of step.In oil cylinder 3, be provided with plunger 5, plunger 5 right-hand member joint pin stopper rods 6, plunger rod 6 right-hand members stretch out outside oil cylinder 3, and plunger rod 6 outer ends are provided with one section of right screw rod 61 of step.Brake gear also comprises two vertical clamping handles 7, two clamping handles 7 are symmetrical arranged along the vertical axis of wheel 2, in the middle of two clamping handles 7, by first, ship and resell on another market respectively 8 hinged with frame 1, two clamping handle 7 upper ends stretch out and by nut, are fixed on left screw rod 41 and right screw rod 61 respectively, the both sides of vehicle bridge 9 curved are stretched to respectively in the lower end of two clamping handles 7, between the arc lower end 71 of two clamping handles 7 and vehicle bridge 9, be respectively equipped with the friction lining 10 of arc, ship and resell on another market and 101 be hinged on the fixed block that frame 1 stretches out downwards by second in two friction lining 10 lower ends, when static, the arc lower end 71 inner side laminatings of friction lining 10 outsides and clamping handle 7, certain gap is left with vehicle bridge 9 in inner side.
When needs brake, foot-treadle, open valve, pump is squeezed into left oil port 31 by oil by oil pipe and is entered in oil cylinder 3, now, thereby the plunger 5 in oil cylinder 3 can promote plunger rod 6 toward moving right toward moving right owing to being subject to oil pressure, right oil port 32 is fuel-displaced, thereby oil cylinder 3 left ends also can drive the left connecting rod 4 being connected with its left end toward moving left toward moving left owing to being subject to the effect of oil pressure simultaneously, drive left connecting rod 4 and plunger rod 6 to move to two ends, and then open outward the upper end of two clamping handles 7 being connected respectively with plunger rod 6 outer ends with left connecting rod 4 of drive, 8 hinged with frame 1 owing to shipping and reselling on another market by first in the middle of clamping handle 7, the arc lower end 71 of two clamping handles 7 will inevitably inwardly be held friction lining 10 tightly, and be with movable friction plate 10 inwardly to rely on vehicle bridge 9 and realize brake.When brake is complete, pin is unclamped from stretcher, valve can be controlled right oil port 32 oil-feeds from oil cylinder, fuel-displaced from left oil port 31, now left connecting rod 4 and plunger rod 6 inwardly shrink, drive the upper end of two clamping handles 7 toward interior contraction, and then drive the arc lower end 71 of two clamping handles 7 to open outward, thereby make friction lining 10 outwards leave vehicle bridge 9.
The brake gear of a kind of railroad hauling car that the utility model provides, changes original one-way brake into bilateral braking, and clamping handle 7 is bilateral to be held tightly, and friction lining 10 is braked from the bilateral of vehicle bridge 9, and braking effect is good; It is controlled by hydraulic oil simultaneously, safe and reliable; Only need the foot-treadle just can attainment brake hydraulic pressure, easy to operate.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
