The conveying belt deflection signal detection device comprises a deflection distance detection mechanism arranged at two sides of the conveying belt and a conversion circuit for converting the detected deflection distance into an electric signal. The conveying belt deflection signal detection device of the utility model can effectively reflect the deflection signal of the conveying belt and ensure the normal operation of the conveyor.
Description
Technical field
A kind of detecting device of the utility model relate generally to relates to a belt deflection signal supervisory instrument especially.
Background technology
The load-transfer device of belt conveyer be the traction object be again load-carrying element, support and carry bulk material load, the loading and unloading that are widely used in large bulk materials such as coal, ore, grain, cement are carried, but when transporting above-mentioned large bulk material, because converyor roller axle system is eccentric, discharging point is offset, loads reasons such as inhomogeneous, can cause the sideslip accident of load-transfer device.Belt deflection may cause belt edges to rub mutually with frame, influences its service life; Or directly cause the generation of spreading accident.
For preventing the serious sideslip of load-transfer device, the sideslip switch all is installed on large conveying quantity, long belt conveyor, when load-transfer device generation sideslip higher limit, in time send the sideslip alerting signal.But the sideslip switch that uses only is a simple proximity on and off switch at present, can't obtain the continuous signal of belt deflection amount size, thereby can not realize the purpose of automatically correcting error of conveyer belt.
The utility model content
The purpose of this utility model provides a kind of belt deflection signal supervisory instrument, with the continuous signal of belt deflection amount size, thus the purpose of realization automatically correcting error of conveyer belt.
The technical matters that the utility model solved can realize by the following technical solutions:
A kind of belt deflection signal supervisory instrument comprises: be arranged on the sideslip distance detecting mechanism of load-transfer device both sides and detected sideslip distance changed into the change-over circuit of electric signal.
In the utility model, described sideslip distance detecting mechanism comprises:
One base;
One is arranged on the housing on the base, and housing is provided with a rotating shaft, and rotating shaft is provided with a cam to lower convexity, cam be provided with one straight up can with the push rod of cam coaxial rotation, the push rod sidewall is pressed close to belt edges;
One is arranged on the base and is positioned at cam below osed top hollow housing, and described hollow housing inner close fitting base is provided with a pressure-strain sheet, and pressure-strain sheet top is provided with a pressure spring, and described pressure spring top is provided with the push rod that a top and cam edge are pasted mutually.
Described change-over circuit comprises by pressure-strain sheet and other three electric bridges that precision resistance constitutes, with electric bridge bonded assembly signal conditioning circuit, the electric current loop that is connected final output current signal with signal conditioning circuit has realized that thus the physical quantity of sideslip distance changes the magnitude of current into.
Belt deflection signal supervisory instrument of the present utility model can react the offset signals that output is with effectively, has guaranteed the normal operation of conveyer.
Description of drawings
Fig. 1 is the utility model sideslip distance detecting structural scheme of mechanism.
Fig. 2 is the interconnecting wiring diagram of the utility model signaling conversion circuit.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of belt deflection signal supervisory instrument, in order to detect and export the running deviation value of load-transfer device, it comprises deviation detecting device, and deviation detecting device comprises: be arranged on the sideslip distance detecting mechanism 1 of load-transfer device both sides side and sideslip distance changed into the change-over circuit of electric signal.
As shown in Figure 1, sideslip distance detecting mechanism 1 comprises base 11, base is provided with housing 12, housing 12 is provided with a rotating shaft 13, rotating shaft 13 is provided with a cam 14 to lower convexity, cam 14 is provided with straight up a push rod 15, push rod 15 can with cam 14 coaxial rotation, push rod 15 upper end sidewalls are pressed close to load-transfer device 3 edges; The base 11 of cam 14 belows is provided with an osed top hollow housing 16, hollow housing 16 inner close fitting bases 11 are provided with a pressure-strain sheet 17, pressure-strain sheet 17 tops are provided with a pressure spring 18, and pressure spring 18 tops are provided with a push rod 19, and paste mutually with cam 14 edges on push rod 19 tops.
Sideslip takes place in load-transfer device 3, and load-transfer device 3 promotes push rod 15 and pivots, and its push rod corner α becomes sinusoidal function relation with load-transfer device 3 running deviation value x:
Drive cam 14 during rotating shaft 13 rotations push rod 19 is pressed down, the pressure that produces by pressure spring 18 acts on pressure-strain sheet 17, and the resistance value Rx of pressure-strain sheet 17 is changed, and its variation delta Rx is directly proportional with corner a:
ΔR
x＝k
1a。
Pressure-strain sheet 17 is constituted the dc balance electric bridge with precision resistance R2, R3, R4, and this millivolt level (mV) signal can take out, and as shown in Figure 2, establishes:
R
2＝R
3＝R
4＝R，R
x＝R(1+ΔR
x)
Direct current bridge output signal then:
Vs is a bridge power supply in the formula, output voltage signal V and corner a direct ratio.Electric bridge connects signal conditioning circuit 21, and signal conditioning circuit 21 connects electric current loops 22, but signal conditioning circuit 21 filter out background noise and signal amplified after the belt deflection current signal of electric current loop 22 output 4-20mA.What it will be appreciated by those skilled in the art that is, the offset signals of output can be voltage signal fully, and does not influence enforcement of the present invention fully, and wherein signal conditioning circuit 21 and electric current loop 22 are prior art all, and are widely adopted, this just tired having stated.
More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
