Abstract
The utility model discloses a detecting device for material shortage of belt, which comprises a base plate (1), two supporting seats (2) are provided at the lower part of the base plate (1), two ends of a revolving shaft are arranged in the supporting seats (2), a check-out console (4) is arranged on the intermediate part of the revolving shaft, an approach plate (5) is provided at the right side of the intermediate part of the revolving shaft, and an approach switch (6) is arranged on the right seat (2). The detecting device for material shortage of belt has the advantages of normal operation, sensitive and reliable signal, and low failure rate. The detecting device for material shortage of belt completely solves the long-term existed problem of coal shortage in an intermediate pressure system coal feeder.
Description
Technical field
The utility model relates to a kind of detecting device.
Background technology
The disconnected coal detecting device that uses now all adopts common iron to make, and moves switch as signal source with magnetic.Its rotatable parts often all can occur because of the stuck situation that can't normal operation of corrosion; Add magnetic moving switch leak tightness, resistance to corrosion and the moisture resistance inequality of employing; Be prone to misoperation, can not accurately provide coal or not have the correct signal of coal, so cause the medium voltage network feeder coal detecting device cisco unity malfunction that breaks; And because disconnected coal detecting device is installed in the feeder, maintenance is difficulty very.
Summary of the invention
The technical matters that the utility model will solve: a kind of anticorrosive, sensitive failure-free fracture detecting device is provided, to solve the problem of existing detecting device easy-to-rust and false positive signal.
The technical scheme of the utility model:
A kind of belt fracture detecting device comprises that base plate, floor below are equipped with two bearings, and the two ends of rotating shaft are installed in the bearing, and its stage casing is equipped with check-out console, and the right side in rotating shaft stage casing is equipped with near plate, is equipped with near switch on the bearing on the right.
The structure of whole device is made by corrosion-resistant steel.
The beneficial effect of the utility model:
The corrosion-resistant steel resistance to corrosion is strong, near switch sealing, moistureproof, anti-dust performance is good, highly sensitive; When feeder has coal, the lever check-out console is held up, this moment is give a signal not normally; When feeder did not have coal, the lever check-out console fell, and connected near switch, sent the coal cutting off alarm signal.Through using, system works is normal, and signal is sensitive reliable, and fault rate is low.The disconnected coal that satisfactorily resolves the medium voltage network feeder detects long-standing problem.
Description of drawings:
Fig. 1 is the utility model scheme drawing.
The specific embodiment:
Embodiment: as shown in Figure 1, below base plate 1, be provided with two bearings 2, rotating shaft 3 is installed in the middle of the bearing 2; The stage casing of rotating shaft 3 is equipped with check-out console 4; The right side in stage casing is equipped with near plate 5, is equipped with near switch 6 on the bearing 2 on the right, and be that capacitor induction type is near switch near switch 6.This device of perforate installation of 150*200 is opened at about one meter behind feeder back entrance door, and the below of inferior device is a coal conveyer belt.
Principle of work, when on the belt coal being arranged, check-out console 4 is held up, and breaks away near switch 6 near plate 5, closes near switch 6, and when not having coal to carry, check-out console 4 is sagging, and is also sagging synchronously near plate 5, near near switch 6, opens near switch 6, sends disconnected coal signal.
Claims (2)
1. belt fracture detecting device; Comprise that base plate (1), base plate (1) below are equipped with two bearings (2); The two ends of rotating shaft (3) are installed in the bearing (2); Rotating shaft (3) stage casing is equipped with check-out console (4), it is characterized in that: the right side in rotating shaft (3) stage casing is equipped with near plate (5), is equipped with near switch (6) on the bearing on the right (2).
2. belt fracture detecting device according to claim 1, it is characterized in that: the structure of whole device is made by corrosion-resistant steel.
