Abstract
The utility model discloses an emergency stop switch of a mine belt conveyor. The emergency stop switch of a mine belt conveyor comprises a casing cover, a casing body, a travel switch, a wiring bank, a cam, an operating lever, a rotating shaft, a torsion spring and a reset handle. When the emergency stop switch is in the normal state, the operating lever is at a vertical position. When the belt machine breaks down and emergency stop is needed, the operating lever is pulled, the cam rotates to push the travel switch to be closed, a control signal is output, and the purpose of emergency stop is realized. According to the utility model, the original structure is simplified; dustproof and waterproof abilities are strong; the travel switch and the wiring bank are reasonably arranged, thus wiring is convenient; and when the operating lever is pulled to a designed action angle, a positioning pin which is connected with the reset handle is inserted into a positioning hole in the cam under the action of the spring, thus the firm locking of the position of the operating lever is realized, and the phenomenon of tripping of the existing emergency stop switch is avoided.
Description
Technical field
The utility model relates to a kind of mine belt conveyor emergency stop switch.
Background technology
Emergency stop switch is mainly used in ribbon conveyer, mainly is comprised of control handwheel, draw ring, rotating shaft, cam, line bank and travel switch.When ribbon conveyer was normal, control handwheel was in vertical position.When breaking down, the pulling draw ring drives control handwheel, and control handwheel drives rotating shaft and cam reaches design action angle and latched position, and cam touches travel switch output control signal shuts down conveyer.After the trouble shooting, by lower shift fork control handwheel is resetted after, can again start shooting.
There is following defective in existing emergency stop switch:
1. thread off easily.The control handwheel position can not lock when namely breaking down, or can not reset after the locking.
2. operating angle is wayward.Namely do not reach the action of design action angle emergency stop switch, or be failure to actuate above the design action angle.
3. wiring is inconvenient.Because topology layout is unreasonable, cable is difficult for passing introducing device and receives on the line bank.
4. dust-proof effect is poor.Dust is overstock at the control handwheel place easily, and impact is normally used.
The utility model content
The utility model purpose is in order to remedy the defective of prior art, a kind of rational in infrastructure, service-strong mine belt conveyor emergency stop switch to be provided.
The technical solution of the utility model is as follows:
A kind of mine belt conveyor emergency stop switch, include cap, housing, travel switch, line bank, cam, joystick, rotating shaft, torsion spring and the handle that resets, it is characterized in that: described rotating shaft is rotatably installed in the housing, one side outer wall of described housing is provided with perforate, one end of described rotating shaft passes described perforate and extends, described action bars is fixedly mounted on the end of an end of described rotating shaft, the eccentric position of described cam is provided with through hole, cam is sleeved in the rotating shaft by described through hole, described travel switch is fixedly mounted in the cap, the outer of the cam relative with through hole is provided with the contact, and described contact is positioned at the below that travel switch gets an electric shock; The housing outer wall that is positioned at rotating shaft one side is provided with aperture, the described front end that resets handle inwardly passes aperture and extends in the housing, the front end of shaking hands that resets is provided with stepped hole, stepped hole is interior by the alignment pin that has been slidingly installed, described alignment pin outer cover is equipped with spring, one end of described spring leans the end at alignment pin, and the other end of spring leans on the step surface of stepped hole, and the cam face relative with alignment pin is provided with location hole; Described travel switch is electrically connected with the lugs of belt feeder by line bank, and described torsion spring set is contained in the outside of cam.
Described mine belt conveyor emergency stop switch is characterized in that: the faying face of described cap, housing is provided with sealing gasket.
Described mine belt conveyor emergency stop switch is characterized in that: be respectively equipped with O RunddichtringO and oil sealing between the inwall of described perforate and the mating surface of rotating shaft.
Principle of the present utility model is:
Joystick was in vertical position when emergency stop switch was in normal condition, and when belt feeder breaks down must stop in emergency the time, pulling joystick, cam rotate that to promote travel switch closed, and the output control signal realizes the purpose of stopping in emergency.
The beneficial effects of the utility model:
1. when pulling joystick when reaching the design action angle, and the alignment pin that links together of the handle that resets inserts under spring action in the location hole on the cam, can realize securely the locking of stick position, avoided the dropout phenomenon of existing emergency stop switch.
2. because the position of cam and alignment pin is fixed, just the problem of operating angle deviation can not appear.
3. the utility model has been simplified original structure, its travel switch and line bank and rational deployment, thus make wiring convenient.
4. adopt gasket structure between cap and the housing, an end of the rotating shaft that is connected with joystick has adopted the structure of oil sealing and O RunddichtringO, has strengthened dustproof, waterproof ability.
