Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to an inclined iron type roof separation sensor for mines. Background Art

[0002] The mining roof separation sensor measures the displacement of the outer layer of the roof relative to the inner layer of the roof, thereby monitoring the deformation of the roof separation. The current roof separation sensor is used to detect the displacement of the steel rope, and then detect the roof separation status. The structure is usually a roller type, that is, the steel rope is wrapped around the roller, and the roof separation information can be transmitted to the roller through the steel rope, and then driven by a worm gear transmission or a gear transmission to drive the pusher to move, and finally the cantilever beam is pushed by the pusher to produce deformation, so as to realize real-time monitoring of the roof separation status information. This detection method has a relatively complex transmission structure, and detection deviations are likely to occur during the transmission process, affecting the accuracy of the detection results. Moreover, the complex transmission structure makes the sensor have a larger volume and is less convenient to install. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides an inclined iron type mine roof separation sensor.

The main frame is also provided with a first guide wheel. The detection module also includes a first steel rope, which bypasses the first guide wheel and is connected to one end of the iron plate strip, and is arranged to be able to pull the iron plate strip to slide. On the basis of this structure, the movement of the first steel rope can be more accurately and quickly fed back to the iron plate strip, and through the sliding of the iron plate strip, the cantilever beam is driven to deform, thereby completing the monitoring of the roof separation status information. The transmission structure is simpler and the installation is more convenient.

[0006] As described above, an inclined iron type mining roof separation sensor, the detection module also includes a second steel rope with one end connected to the other end of the iron plate strip, a second guide wheel is provided on one side of the main frame, the other end of the second steel rope passes around the second guide wheel and is connected to the main frame through a tension spring. On the basis of this structure, when the first steel rope contracts, the iron plate strip can be pulled to reset through the tension spring and the second steel rope, thereby ensuring that the iron plate strip can move back and forth under the action of the first steel rope and the second steel rope, thereby ensuring the accuracy of the roof separation status information monitoring results.

[0007] As a preferred embodiment, in order to ensure the sliding stability of the iron strip, a U-shaped block is provided in the middle of the main frame, and the iron strip passes through the opening of the U-shaped block and slides and fits with the U-shaped block on both sides.

[0008] On the basis of the above structure, in order to ensure the stability of the sliding fit between the cantilever beam and the iron strip, the cantilever beam is pressed and fixed on the U-shaped block by a pressing block.

[0009] As a further preferred embodiment, in order to further ensure the stability of the sliding fit between the cantilever beam and the iron strip, two U-shaped blocks are provided, one end of the cantilever beam is pressed and fixed on one of the U-shaped blocks by a pressing block, and the other end is located between the two U-shaped blocks.

[0011] In order to ensure the stability of the iron strip sliding along the main frame, sliding blocks are provided at both ends of the iron strip, and the iron strip is slidably connected to the main frame through the sliding blocks.

[0012] The inclined iron type mine roof separation sensor as described above is provided with two sets of detection modules in parallel to facilitate the detection of separation information at deep base points and shallow base points and ensure the accuracy of separation information monitoring.

[0013] As a preferred embodiment, the first guide wheel of the detection module in the same group is located in the middle of the main frame and two are provided on the side of the main frame away from the second guide wheel, so that the first steel ropes of the two groups of detection modules can be led out centrally, facilitating the arrangement of the top plate separation sensor.

[0014] The beneficial effect of the utility model is that the utility model is an inclined iron type mine roof separation sensor. The movement of the first steel rope can be more accurately and quickly fed back to the iron strips, and the sliding of the iron strips can drive the cantilever beam to deform, thereby completing the monitoring of the roof separation status information.

The structure of the roof separation sensor (the above-mentioned inclined iron type mine roof separation sensor) is described in detail below.

[0025] In this embodiment, combined with Figure 2 As the core technical concept of the present invention, the detection module 3 includes an iron plate 31 slidably arranged on the main frame 2, and a cantilever beam 38 arranged on the main frame 2 and one end of which is in sliding contact with one side of the iron plate 31, and the contact side of the iron plate 31 and the cantilever beam 38 is an inclined surface structure which is not parallel to its sliding direction. A first guide wheel 33 is also provided on the main frame 2, and the detection module 3 also includes a first steel rope 34, which bypasses the first guide wheel 33 and is connected to one end of the iron plate 31, and is configured to be able to pull the iron plate 31 to slide. On the basis of this structure, the action of the first steel rope 34 can be more accurately and quickly fed back to the iron plate 31, and through the sliding of the iron plate 31, the cantilever beam 38 is driven to deform, thereby completing the monitoring of the top plate separation status information, and the transmission structure is simpler and the installation is more convenient.

[0026] Specifically, combined with Figure 3 The main frame 2 includes a horizontally arranged frame plate 21, and the frame plate 21 includes a horizontally arranged rectangular middle plate 211, and strip-shaped side plates 212 horizontally arranged in the middle of both sides of the middle plate 211, and the center lines of the two side plates 212 along the length direction are collinear, and the middle parts of the side plates 212 on both sides are provided with strip-shaped sliding openings 2121 along their length direction. Slide blocks 32 are provided at both ends of the iron plate strip 31, and the slide blocks 32 at both ends are slidably connected to the sliding openings 2121 in the middle of the two side plates 212 of the main frame 2. The cross-section of the slider 32 is a U-shaped structure, and one side of its opening is connected to the iron plate strip 31. The slider 32 is arranged in the sliding opening 2121 and is clamped on one side of the sliding opening 2121 through the opening, so that the iron plate strip 31 can slide above the horizontal plane where the frame plate 21 is located, thereby ensuring the stability of the iron plate strip 31 sliding along the main frame 2.

[0028] On the basis of the above structure, as for the fixing method of the cantilever beam 38, in order to ensure the stability of the sliding fit between the cantilever beam 38 and the iron plate strip 31, the cantilever beam 38 is pressed and fixed on the upper side of the U-shaped block 4 by a pressing block 5.

On the basis of this structure, when the first steel rope 34 contracts, the iron strip 31 can be pulled to reset through the tension spring 37 and the second steel rope 36, so as to ensure that the iron strip 31 can move back and forth under the action of the first steel rope 34 and the second steel rope 36, thereby ensuring the accuracy of the monitoring results of the top plate separation status information.
