Fig. 2 is the utility model structural drawing.
The corresponding explanation of accompanying drawing number: 1, jiggering ratchet; 2, moving tooth bar; 3, sensing plate; 4, mounting plate; 5, check ring; 6, return spring; 7, flange land; 8, connecting plate; 9, spacer; 10, frame; 11, cylinder body; 12, termination seat; 13, oil inlet pipe; 14, blind hole; 15, piston; 16, flame-proof switch; 17, oil inlet hole; 18, seal ring.
Embodiment
The utility model is mainly used in that large-scale TRT hydraulic power dish is moving changes trains or buses, and the utility model is installed in large-scale TRT main frame spiral case fore bearing casing.
The utility model in force, also comprises hydraulic control system and electric control system.Hydraulic control system and electric control system are laid by the disclosed mode of patent ZL2009200811129.
The utility model working principle and mode are:
In the time of the moving TRT jiggering of needs dish, under the control and monitoring of control system, start power oil station, come to the hydraulic oil of power oil station, up through in-line, oil inlet pipe (metallic hose) inlet end headstock 12 interior promotion pistons 15, thus drive moving tooth bar 2 up, when moving tooth bar 2 goes upward to its end, just engage with the tooth of the jiggering ratchet 1 of installing on TRT rotor, rotate thereby promote jiggering ratchet 1, coil the work of changing a job.In the time that moving tooth bar 2 goes upward to extreme higher position, the sensing plate 3 of its end triggers flame-proof switch 16, and flame-proof switch 16 detects after sensing plate 3, sends electrical signal to PLC, the power-off of PLC commander solenoid directional control valve, and open the passage that pressure oil leads to power fuel tank.Now no longer pressurized of piston 15, be subject to the effect lower piston 5 of return spring power 6 descending, and it is descending to carry moving tooth bar 2, and oil inlet hole, oil inlet pipe, the return line of the hydraulic oil in cylinder body on the seat of termination flows back to power oil station.Through repeatedly operation, can meet jiggering requirement in a manner described.
The outer surface of inner surface of cylinder block of the present utility model and piston rubs at work repeatedly, loss ratio is larger, in order to improve jiggering working life, should by improve inner surface of cylinder block and piston outer surface add technique, material heat treatment mode improves its surface property.The technique and the processing mode that adopt are unrestricted at this, all can as long as can reach surface property.
