Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of rail breaker, with solve prior art exist security performance lower, require high weak point.

The technical scheme solved the problems of the technologies described above is: a kind of rail breaker, comprise basis, tup, frame, lifting and trip mechanism, safety guard net, described frame is fixed on basis, safety guard net is arranged on the surrounding of frame, it is characterized in that: described frame is provided with two vertical guide rails, described tup is between two guide rails, and the both sides of tup are respectively equipped with concave groove, tup is coordinated with slide by this concave groove, the top of tup with tup can be promoted to the lifting that object height also discharges and be connected with trip mechanism.

Further technical scheme of the present utility model is: described lifting and trip mechanism comprise lifting gear, detacher, described lifting gear comprises windlass, height lead limit switch, height lead limit switch is fixed on the guide rail of frame, and height lead limit switch is arranged in the circuit for controlling motor of windlass.

Further technical scheme more of the present utility model is: described windlass comprises motor, speed reduction unit, cylinder, pulley, wire rope, the input end of motor is connected with power supply by isolating switch, magnetic starter successively, and is in series with described height lead limit switch in the connecting circuit of power supply and magnetic starter; The output terminal of motor is connected with the drum shaft of cylinder by speed reduction unit, this motor, speed reduction unit and cylinder are fixed on basis, the pulley of windlass is fixed on the top of frame, and the wire rope of windlass is from this pulley through being connected with detacher, and detacher hooks on the suspension ring at tup top.

Further technical scheme more of the present utility model is: be provided with the rail bearing for installing rail sample below described tup, this rail bearing is slot type bearing, and the bottom of rail bearing is fixed on basis.

Further technical scheme more of the present utility model is: described frame is also provided with keel type stiffening rib.

Owing to adopting said structure, the rail breaker of the utility model compared with prior art, has following beneficial effect:

1. security performance high, require low:

Because the utility model is provided with two vertical guide rails in frame, described tup is between two guide rails, and the both sides of tup are respectively equipped with concave groove, tup is coordinated with slide by this concave groove, the top of tup with tup can be promoted to the lifting that object height also discharges and be connected with trip mechanism.During work, be placed on bearing by sample rail, promote and tup is promoted to object height with trip mechanism and discharges, tup falls impact on rail sample along guide rail, completes subject performance.Therefore, tup of the present utility model falls along guide rail, and the peril produced when tup freely falling body both can have been avoided to be subject to side impacting force, can avoid again tup guide rod landing mode to require higher weak point.

2. easy to operate:

The utility model operationally, be placed on bearing by sample rail, encounter height travel switch when tup is promoted to object height by windlass, height travel switch disconnects by the circuit for controlling motor of windlass, the motor stalls of windlass, tup no longer rises; That presses detacher shakes control switch, and detacher discharges by tup, and tup falls impact on rail sample along guide rail, can complete subject performance, operation is very easy for it, simple.

3. structure is simple, and cost is low:

Of the present utility model relatively simple for structure, cost is lower, is easy to promote the use of.

Below, in conjunction with the accompanying drawings and embodiments the technical characteristic of the rail breaker of the utility model is further described.
