Important transportation equipment when slat conveyer is mined as underground coal mine, not only as the orbit of coalcutter, also for coalcutter provides traction and guiding, and simultaneously for hydraulic support provides point of connection, thus realize hydraulic support and slat conveyer is constantly passed along coal face direction of propulsion.
Because slat conveyer can become the bridge of coalcutter and hydraulic support, can slat conveyer smooth operation, directly can affect carrying out smoothly of coal mining activity.Testing the every mechanics parameter of slat conveyer, is the important means of the every mechanical characteristic of research slat conveyer, is also the precondition ensureing slat conveyer smooth operation.
In slat conveyer actual moving process, find that the middle pan of scraper conveyor can be damaged because corner is excessive, once damaging appears in the middle pan of scraper conveyor, slat conveyer forced outage will be caused, impact to the normal coal mining activity in down-hole.Technical personnel is urgently wanted to understand the relation between the middle pan of scraper conveyor corner and damage rate for this reason, but first necessary Obtaining Accurate the middle pan of scraper conveyor corner data, technical personnel is retrieved through a large amount of technology, result does not find a kind of existing means can meet the measurement of the middle pan of scraper conveyor corner, therefore, present stage needs a kind of device being applicable to the middle pan of scraper conveyor roll angle inspection badly, with meet technical personnel to the middle pan of scraper conveyor corner data study in the urgent need to.
Summary of the invention
For prior art Problems existing, the invention provides a kind of the middle pan of scraper conveyor rotation angle detecting apparatus, the corner of the middle pan of scraper conveyor can be detected by real-time online, and provide corner data accurately to study for technical personnel.
To achieve these goals, the present invention adopts following technical scheme: a kind of the middle pan of scraper conveyor rotation angle detecting apparatus, comprise coder, expansion link, ball-and-socket type joint, the first fixed mount and the second fixed mount, described coder is fixedly mounted on the first fixed mount, and coder is vertically arranged, coder rotating shaft is installed with gripping sleeve; Described expansion link is horizontally disposed with, and expansion link one end is fixedly connected on gripping sleeve, and the expansion link other end is connected with ball-and-socket type joint; Described second fixed mount is vertically provided with chute, and described ball-and-socket type joint is positioned at chute, and ball-and-socket type joint vertically can slide along chute, and freely can rotate in chute.
Described coder adopts absolute optical encoder.
Above described coder, be provided with the first protective case, above described chute, be provided with the second protective case.
Described first protective case and the second protective case in the vertical direction are staggeredly arranged.
Beneficial effect of the present invention:
After the present invention and the middle pan of scraper conveyor are assembled, the corner of the middle pan of scraper conveyor can be detected by real-time online, and provide corner data accurately to study for technical personnel, help the relation between technical personnel understanding the middle pan of scraper conveyor corner and damage rate, and help technical personnel to design structure more reasonably slat conveyer, ensure the operation that slat conveyer can be more stable, thus ensure carrying out smoothly of coal mining activity.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, a kind of the middle pan of scraper conveyor rotation angle detecting apparatus, comprise coder 1, expansion link 2, ball-and-socket type joint 3, first fixed mount 4 and the second fixed mount 5, described coder 1 is fixedly mounted on the first fixed mount 4, and coder 1 is vertically arranged, coder 1 rotating shaft is installed with gripping sleeve 6; Described expansion link 2 is horizontally disposed with, and expansion link 2 one end is fixedly connected on gripping sleeve 6, and expansion link 2 other end is connected with ball-and-socket type joint 3; Described second fixed mount 5 is vertically provided with chute 7, and described ball-and-socket type joint 3 is positioned at chute 7, and ball-and-socket type joint 3 vertically can slide along chute 7, and freely can rotate in chute 7.
Described coder 1 adopts absolute optical encoder.
Above described coder 1, be provided with the first protective case 8, above described chute 7, be provided with the second protective case 9.
In order to prevent the first protective case 8 and the second protective case 9 from moving interference in operation process, described first protective case 8 and the second protective case 9 in the vertical direction are staggeredly arranged.
Below in conjunction with accompanying drawing, a use procedure of the present invention is described:
As shown in Figure 2, rotation angle detecting apparatus 12 of the present invention is installed in the middle pan of scraper conveyor.Before installing, first on slat conveyer, choose two adjacent place's intermediate channel, be defined as front center groove 10 and rear end intermediate channel 11 respectively, and rotation angle detecting apparatus of the present invention is positioned at front center groove 10 and rear end intermediate channel 11 joint, wherein the first fixed mount 4 is fixedly connected with the backboard of front center groove 10, second fixed mount 5 is fixedly connected with the backboard of rear end intermediate channel 11, and now expansion link 2 is connected between the backboard of front center groove 10 and rear end intermediate channel 11, as shown in Figure 3.
