Abstract
The invention discloses a material disconnection warning device for a conveyer belt, which comprises a protective fixing device, a free swing device, a swing angle detecting device and a signal output device. The protective fixing device is used for mounting the free swing device, the swing angle detecting device and the signal output device, and provides protection function at the same time; the free swing device comprises a shaft and a pendulum, wherein the shaft is fixed on the protective fixing device, the pendulum can rotate around the shaft within a certain angle, the angle changes along with change of thickness of a material on the conveyer belt, and length and shape of the pendulum are selected according to size of the conveyer belt; and the signal output device is used for providing warning signal output, and sometimes, the swing angle detecting device has single output function synchronously.
Description
[technical field]
The present invention relates to alarming device for material cut-off, be meant that especially what send a kind of alarming device for material cut-off of conveyer belt of alerting signal according to material on the measurement load-transfer device.
[background technology]
In industries such as chemical industry, metallurgy, coal, electric power, agriculturals, in the process of its convey materials, often need to measure on the load-transfer device material what, reduce the timely auto alarm of needs if occur flow on the load-transfer device.
Existing metering system has: belt claims, nuclear weigh instrument, tilt switch, super sonic coal current sensor, chute blockage switch.
Belt claims directly to measure the weight of material on the load-transfer device, and it is bigger influenced by belt tension, involves great expense.Precision is low, and the inhomogeneous time error of material is bigger, and various in addition dynamic belts claim that specific limit is arranged, and its complex structure involves great expense simultaneously, installs and safeguard inconvenience.
Nuclear weigh instrument adopts kernel method to measure the thickness of material on the load-transfer device, involves great expense, and strong radiation source is arranged, and use, maintenance, handling cost are very high, and this equipment also can produce certain harm to operating personal and other staff's health simultaneously.
Tilt switch, the inner mercury that adopts is done conductor, when run-off the straight to the 15 ° left and right sides, be switched on or switched off switch, send warning, cable links to each other with measuring head, internal switch is directly clashed into, rapid wear, this equipment also can produce certain harm to the health of operating personal simultaneously.
Super sonic coal current sensor and chute blockage switch use with pipeline in coal stream detect, professional very strong, application is restricted.
[summary of the invention]
The objective of the invention is to overcome the shortcoming of prior art, a kind of alarming device for material cut-off of conveyer belt is provided.
This device contains protection anchor fitting, the device that freely swings, pendulum angle detecting device and signal output apparatus.The protection anchor fitting is used to install pendulous device, pendulum angle detecting device and signal output apparatus, and safeguard function is provided simultaneously.The device that freely swings comprises axle and pendulum, axle is fixed on the protection anchor fitting, pendulum can be swung certain angle around axle, angular dimension changes with material thickness on the load-transfer device, should be according to the size of load-transfer device, select the length and the shape of pendulum, metal, magnet or other special materials are adopted according to the requirement of pendulum angle detecting device in the upper end of pendulum.The pendulum angle detecting device can be micro-switch, travel switch, Hall element, displacement pickup, angular transducer etc. can the perception pendulous device device of swing.Signal output apparatus is used to provide alerting signal output, and the pendulum angle detecting device possesses the signal output function simultaneously sometimes; Signal output has relay tip output, indicator lamp demonstration etc. usually.
Concrete technical scheme is: the protection anchor fitting can be one section steel pipe, square box, inner through processing cylinder or other shapes be used to protect and install the housing of device, pendulum angle detecting device and signal output apparatus of freely swinging, provide entire measuring device using on-the-spot fixed orifice or fixing snap ring etc. simultaneously.Signal output apparatus is fixed in the protection anchor fitting with screw, accepts the signal of pendulum angle detecting device, after treatment, whether the signal of material is arranged on the output load-transfer device.The pendulum angle detecting device is fixed in the protection anchor fitting with screw.The oscillating axle of device of freely swinging is connected on the protection anchor fitting, and pendulum can be freely swung.
When not having material on the load-transfer device, pendulum is in free hang, when material thickness on the load-transfer device increases, pendulum is subjected to the material collision and raises, and depart from free hang, the pendulum angle detecting device detects this state, signal output apparatus according to material on the load-transfer device what so that send warning.Alarming device for material cut-off of conveyer belt, can the perception load-transfer device on the height of material, send warning according to the warning limit value that can set, material on the load-transfer device what can reflect.
The good effect of a kind of alarming device for material cut-off of conveyer belt disclosed in this invention is:
(1) this device is made simple, with low cost;
(2) this device is simple to operate, and maintenance cost is also lower;
(3) effect of this device warning is comparatively obvious, i.e. reaction is very fast, and its reliability is better simultaneously;
(4) this device does not all have to pollute safety and environmental protection to human body and environment;
(5) this device can be applicable to chemical industry, metallurgy, coal, electric power, the situation that fields such as agricultural, especially environmental conditions are poor.
[description of drawings]
Fig. 1 is the alarming device for material cut-off of conveyer belt scheme drawing;
Fig. 2 is an alarming device for material cut-off of conveyer belt principle of work scheme drawing.
Label in the accompanying drawing is respectively: 1 protection anchor fitting, 2 pendulum angle detecting devices, 3 oscillating axles, 4 pendulum, 5 signal output apparatus, 6 material cut-off of conveyer belt devices, 7 materials, 8 load-transfer devices.
[specific embodiment]
The specific embodiment of measuring device of blank pile height of the present invention below is provided, 1 embodiment is provided, but the embodiment that provided is provided.
Referring to attached Fig. 1 and 2.This device 6 contains protection anchor fitting 1, pendulum angle detecting device 2, oscillating axle 3, pendulum 4, signal output apparatus 5.The device that freely swings adopts fan-shaped steel disc, and with planar alignment material 7 flow directions of steel disc, increasing perceptual sensitivity, and the fixing magnet steel in the upper end of pendulum; The pendulum angle detecting device adopts dry-reed tube; Signal output is connected to electrical contact in the dry-reed tube.When on the load-transfer device 8 enough mass flows being arranged, material drives fan-shaped steel disc and lifts an angle, makes the magnet steel of laying out away from dry-reed tube, and electrical contact keeps off-state, output open circuit in the dry-reed tube.
When material 7 flows on the load-transfer device 8 reduce to a certain amount of when following, fan-shaped steel disc is tending towards plumbness, makes the magnet steel of laying out near dry-reed tube, electrical contact action in the dry-reed tube, keep coupled condition, output is closed, sends the alerting signal of the material cut-off on the load-transfer device 8.
