Abstract
A belt deviation switch comprises a switch bracket, a movable connecting rod, a magnet block and a magnetic induction switch, wherein the movable connecting rod is mounted on the switch bracket through a support shaft; the upper part of the switch bracket inclines inwards; the movable connecting rod is hinged with the support shaft; the magnet block is connected to the lower end of the support shaft; the magnetic induction switch is correspondingly mounted below the magnet block; the upper part of the movable connecting rod inclines inwards; the inclined angle of the upper part of the movable connecting rod is the same as that of the upper part of the switch bracket; and the switch bracket is mounted on a conveyor machine frame through a fixed seat. The belt deviation switch has the advantages that the size is small; the weight is light; the mounting and the adjusting are convenient; the operation is fast, safe and reliable; signals can be emitted in time; and the property is stable. Therefore, a belt conveyor can operate safely in a harsh production environment for a long time, the position of a fault point can be pointed out from an operating board, and warning signals are emitted to prompt staff for timely maintenance, which greatly reduces the looking up period of the failure and improves the work efficiency.
Description
Technical field
The utility model relates to the sideslip fender guard that reaches ground-surface various belts under a kind of coal mine.
Technical background
" safety regulations in coal mine " 627, regulation belt conveyer should be provided with and prevent the belt deflection protection.It is far away to have a command range for the belt conveyer in mine, and long belt feeder reaches km, for the safe in operation of belt conveyer, must be used for controlling belt and under failure condition, brake at the centring device of establishing of belt feeder, guarantees safe operation.Because the working environment extreme difference under the coal mine, brought very big work capacity to the maintenance of belt deviation device, and dropped into a large amount of diversion fees.Traditional centring device is with the main original paper of mechanical micro-switch as fender guard always; Its explosion-resistant enclosure very fast corrosion under rugged environment in addition; The situation of malfunction and tripping happens occasionally, and has had a strong impact on the long-time running of equipment, causes heavy losses to mine main.
Summary of the invention
The purpose of the utility model is a kind of belt deviation switch of design, to overcome the problem that prior art exists.
Realize that the technical scheme that the utility model purpose is taked is: it is made up of switch bracket, moving connecting rod, magnet piece, Magnetic Induction switch; Moving connecting rod is installed on the switch bracket through pivot shaft; Switch bracket top slopes inwardly; Moving connecting rod is hinged with pivot shaft, and the lower end connects magnet piece, magnetic induction switch of corresponding installation below the magnet piece; Moving connecting rod top slopes inwardly, and the bevelled angle is identical with the angle of switch bracket upper angled; Switch bracket is installed on the belt feeder frame through a permanent seat.
Friction when reducing belt deviation between belt and the moving connecting rod is installed an axis of rolling at moving small end.
The good effect of the utility model is: volume is little, in light weight, convenient mounting and regulation, quick action, and is safe and reliable and can send signal timely; Stable performance; Make can be under the abominable production environment long-term safe operation of band conveyor, and under the situation of fault, can on operator's station, point out the position of trouble point, send alerting signal prompting staff on-call maintenance; Significantly reduce searching the time of fault, increase work efficiency.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model; Accompanying drawing 2 is the left view of accompanying drawing 1.
The specific embodiment
Like accompanying drawing 1, shown in 2; It is made up of switch bracket 6, moving connecting rod 2, magnet piece 4, Magnetic Induction switch 5, moves connecting rod 2 and is installed on the switch bracket 6 through pivot shaft 3, the switch bracket 6 tops 60-70 degree that slopes inwardly; Moving connecting rod 2 is hinged with pivot shaft 3; An axis of rolling 1 is installed in moving connecting rod 2 upper ends, and magnet piece 4 is fixed by bolts to moving end, connecting rod 2 lower end, magnet piece 4 following corresponding magnetic induction switches 5 of installing; The intilted angle in moving connecting rod 2 tops is identical with the angle of switch bracket 6 upper angled; Switch bracket 6 is installed on the belt feeder frame through a permanent seat 7, and moving connecting rod 2 tilts to the belt direction, and the limit portion of belt should be vertical with the axis of rolling 1 of moving connecting rod 2 upper ends.
This switch is in existing position under the normal situation, and under the situation of belt deviation, the edge of belt will touch the axis of rolling 1; To 1 one outside power of the axis of rolling; Connecting rod 2 is subjected to displacement, drives magnet piece 4 displacements simultaneously, make magnet piece 1 depart from Magnetic Induction switch 5; Simultaneously, Magnetic Induction switch 5 sends and stops and alerting signal.
This device is installed in the both sides of belt frame; Directly link to each other with frame through connecting screw; How much can deciding of its installation according to the reality at scene; Its output lead also is connected on the bus on the belt frame, no matter in which section belt generation deviation phenomenon, all can be sent on the operator's station through this bus.
Claims (2)
1. belt deviation switch; It is characterized in that: it is made up of switch bracket, moving connecting rod, magnet piece, Magnetic Induction switch; Moving connecting rod is installed on the switch bracket through pivot shaft, and switch bracket top slopes inwardly, and moving connecting rod and pivot shaft are hinged; Magnetic induction switch of corresponding installation below the lower end connection magnet piece, magnet piece; Moving connecting rod top slopes inwardly, and the bevelled angle is identical with the angle of switch bracket upper angled; Switch bracket is installed on the belt feeder frame through a permanent seat.
2. belt deviation switch according to claim 1 is characterized in that: at moving small end an axis of rolling is installed.
