Abstract
The utility model discloses an off-tracking sensor for a mining belt conveyor. A roller is arranged on one side of a belt conveyor, a rotary shaft is rotatably arranged inside a shell body, an open hole is formed in the outer wall of one side of the shell body, one end of the rotary shaft stretches out of the open hole and extends out of the open hole, the one portion of one end of the rotary shaft is fixedly connected with the bottom portion of a roller through a connecting rod, a through hole is formed in the eccentric position of a cam, and the cam is sleeved on the rotary shaft through the through hole. A travel switch is fixed arranged inside the shell body, a contact is arranged on the outer edge of the cam opposite to the through hole, the contact is arranged on one side of the travel switch, and the side of the travel switch contacts with electricity. The travel switch is electrically connected with the shut-down device of the belt conveyor through a line bank, and a torsional spring is sleeved outside the cam. When the sensor is in a normal state, the roller is arranged on a vertical position. When the belt conveyor is in off tracking failure, and a belt drives the roller to skew for 20 degrees and 35 degrees, the roller drives the cam to rotate and pushes the travel switch to be connected, a control signal is output, and the aim of shut-down is achieved. After the failure is removed, the roller of the sensor recovers to a normal working state relying on the acting force of the spring, and the travel switch is disconnected.
Description
Technical field
The utility model relates to a kind of mine belt conveyor misalignment sensor.
Background technology
Misalignment sensor is used for belt conveyer, mainly is comprised of cylinder, torsion spring, ball pressure head, end housing body, line bank and travel switch.When sideslip did not occur conveyer belt, cylinder did not contact with belt.When the sideslip fault occurring, belt shake-up cylinder makes and departs from the normal position to operating angle, and early warning or stop signal are sent in the lead-out terminal conducting.Behind the Failure elimination, cylinder relies on the application force auto-returned of spring to reset angle, and lead-out terminal disconnects, and returns to normal working.
There is following defective in existing misalignment sensor:
1. be prone to friction force between ball pressure head and end housing body and increase phenomenon, cause cylinder freely not reset.
2. dust-proof effect is poor.Dust is overstock at ball pressure head 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, easy to use and reliable mine belt conveyor misalignment sensor to be provided.
The technical solution of the utility model is as follows:
A kind of mine belt conveyor misalignment sensor, include cap, housing, travel switch, line bank, cam, rotating shaft, torsion spring and cylinder, it is characterized in that: described cylinder is arranged on a side of belt conveyer, described rotating shaft is rotatably installed in the housing, one side outer wall of housing is provided with perforate, one end of described rotating shaft passes described perforate and extends, and captive joint with the bottom of cylinder by connecting rod in the end of rotating shaft one end, 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 housing, the outer of the cam relative with through hole is provided with the contact, and described contact is positioned at the side that travel switch gets an electric shock; 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 misalignment sensor is characterized in that: the faying face of described cap, housing is provided with packing seal.
Described mine belt conveyor misalignment sensor is characterized in that: be respectively equipped with O RunddichtringO and oil sealing between the inwall of described perforate and the fitting surface of rotating shaft.
Principle of the present utility model is:
Joystick was in vertical position when sensor was in normal condition, and when the sideslip fault appearred in belt feeder, when belt promotion cylinder made generation skew 20 degree spend to 35, the drum having moving cam rotated promotion travel switch closure, and the output control signal is realized parking purposes.Behind the Failure elimination, sensor roller relies on the application force of torsion spring to return to normal working, and namely the stroke switch disconnects.
The beneficial effects of the utility model:
1. the utility model has been removed original ball pressure head and end housing body structure, adopts rotating shaft and torsion spring structure, the phenomenon of having avoided cylinder freely not reset.
2. because the position of cam is fixed, just the problem of operating angle deviation can not appear.
3. the utility model is simple in structure, compact, has adopted Novel position switch and line bank and rational deployment, has volume characteristics little, lightweight, easy to maintenance.
4. adopt gasket structure between cap and the housing, its external part has adopted the structure of oil sealing and O RunddichtringO, has strengthened dustproof, waterproof ability.
