The utility model belongs to a special implement for the construction and the maintenance operation of the railway. The utility model is composed of a tension brace bar of the rail, a rail clamping instrument, a guiding rail of the rail clamping instrument, a hydraulic system and a rail interval measuring scale. The hydraulic railway switch is designed with two rail clamping ways which can quickly switch the railway or safely switch the railway. The utility model has the characteristics of reasonable design, convenient use, manpower saving, small size, light weight, good performance, safety, etc., and overcomes the defects of multi-operator operation, labor wasting, large weight, hard precise fixation of the rail interval, etc. in the lever type railway switch.
Description
The utility model is a kind of hydraulic tool that changes card rail mode that is used to adjust the rail gauge, belongs to construction of railways maintenance activity special-purpose machines and tools.
The device that changes its course that adjustment rail gauge used in the past adopts the lever mode to adjust with card rail stay bolt bar.This mode needs human gauging rule calibrating, and two people move crowbar, because the irregular instability of exerting oneself, it is difficult accurately fixing to adjust the gauge size, and still need in addition people's spiking or trip bolt need many people's operations, and the big usage charges power of weight.
The purpose of this utility model provides a kind of hydraulic pressure device that changes its course, and can make the work of adjusting the rail gauge only need a people to finish.This machine work is laborsaving.The gauge adjustment is accurate, safety, and facility are in light weight.
To achieve the above object, the utility model has adopted following solution.Being provided with fixedly at card rail stay bolt bar one end, rail meter blocks an one steel rail, the other end is provided with the rail meter guide rail, be equipped with movable rail meter on the guide rail and block another one steel rail, movable rail meter is connected with oil cylinder, the hydraulic oil that the hand plunger displacement pump is sent enters an end of oil cylinder through reversing switch, promotes piston, and piston rod drive activity rail meter moves, movable rail meter just makes an one steel rail move, and has changed the distance with another one steel rail.At this moment, the pointer of gauge measuring appliance moves to and has just adjusted the rail gauge on the required size.The present invention is easy to use, and people operation can be finished the task of the adjustment gauge that several people's operation simultaneously just can finish.
Fig. 1 is the stereoscopic figure of a kind of concrete structure of the utility model.
Fig. 2 is the rotary reversal valve sectional drawing of the utility model.
Fig. 3 is that rotary reversal valve is along Fig. 2 A-A line sectional view.
With reference to Fig. 1, hydraulic pressure changes its course device by rail stay bolt bar (3), and the card tread is rail meter (2) fixedly, the movable rail meter (5) of card tread, the card flange of rail is rail meter (1) fixedly, the movable rail meter (4) of the card flange of rail, rail meter guide rail (6), oil tank mount (11), single pole two-way ram oil cylinder (7), plunger displacement pump (12), plunger displacement pump handle (9), rotary reversal valve (10) and gauge surveyors' staff (14) constitute.
Rail stay bolt bar (3) adopts seamless steel pipe, in the separated purpose that reaches insulation that connects with high-strength insulating material.
Rail meter has two groups: one group is fixedly rail meter (2) and the movable rail meter (5) of card tread of card tread; Another group is fixedly rail meter (1) and the card movable rail meter of the flange of rail (a 4) composition of the card flange of rail.Fixedly rail meter is fixed by bolts to an end of rail stay bolt bar (3) by key pin, and movable rail meter then is connected to each other with bolt by key pin and is installed on the rail meter guide rail (6).
Rail meter guide rail (6) is the double square guide rail, is welded in rail stay bolt bar (3) other end, and rail meter guide rail (6) is gone up installation activity rail meter (4) (5).
Hydraulic system is by fuel tank (8), plunger displacement pump (12), and rotary reversal valve (10), oil tank mount (11), single pole double acting plug cock oil cylinder (7) is formed.There are two oilholes oil tank mount (11) side, and oil pipe is connected oilhole by screw thread with single pole two-way ram oil cylinder (7).Plunger displacement pump (12) is connected with pump seat by screw thread, be provided with the oily one way valve of turnover in the pump seat, pump seat and rotary reversal valve (10) all are fixed on the oil tank mount (11) with screw thread, establish oil circuit in the oil tank mount (11) and connect each part, single pole two-way ram oil cylinder (7) is fixed on rail meter guide rail (6) other end by flange, and piston rod one end is connected with movable rail meter (4) (5) with the garden pin.
Fuel tank (8) is equipped with plunger displacement pump handle (9) on the top, be processed with rotary reversal valve (10) handle hole, tank filler sleeve (13), plunger displacement pump handle (9) twisted seat etc., fuel tank is fixed by bolts on the oil tank mount (11), and oil tank mount (11) is fixed by bolts to rail meter guide rail (6) top.
With reference to Fig. 2, rotary reversal valve (10) is by valve body (15), rotary valve (23), and sealing ring (17), nylon back-up ring (16), body cap (18) constitutes.On valve body (15), valve body (15) is fixed on the oil tank mount (11) with fluid sealant by screw thread valve gap with bolton.
Fig. 3 is that (10) two duties of rotary reversal valve are along Fig. 2 A-A line sectional view.When being in Fig. 3 .1 state, the hydraulic oil that plunger displacement pump (12) is sent is sent oilhole (22) to by the oil circuit in the oil tank mount (11), send an end of single pole two-way ram oil cylinder (7) to through hydraulic fluid port (19), promote piston motion, other end oil enters fuel tank (8) from oilhole (20) through spill port (21).When being in Fig. 3 .2 state, the hydraulic oil that plunger displacement pump (12) is sent is sent into fuel feed hole (22) by the oil circuit in the oil tank mount (11), send the other end of single pole two-way ram oil cylinder to through oilhole (20), promote piston motion, the oil of the other end enters fuel tank (8) through oil-through hole (19) from spill port (21).
