Description

Technical Field

[0001] The utility model belongs to the technical field of goaf area data detection, in particular to a replaceable three-dimensional data detection device. Background Art

[0002] Currently, the exploration of disaster-causing factors in goafs and surrounding old kilns is becoming increasingly urgent. The spatial distribution characteristics of goafs are primarily determined through geophysical exploration, geochemical exploration, drilling, and 3D scanning. However, some unidentified goafs are difficult to access due to their unknown safety status and are sometimes only discovered during drilling. Conventional techniques are difficult to accurately identify, posing a safety hazard to mining operations. Therefore, there is an urgent need for a device that can accurately measure unidentified goafs through drilling, thereby identifying their spatial distribution characteristics. Specifically, the device can detect anomalies in goafs based on geophysical detection and verify them through drilling. For existing goafs, the device can be used to drill into the goaf for data collection, ultimately yielding an accurate 3D image of the goaf.

[0003] Currently, there are few types of mine goaf detection equipment available, and the cost is high. This puts a certain amount of financial pressure on small and medium-sized enterprises and individual users, making this type of equipment not widely used in the safe mining process of mines, and increasing the potential dangers during mining operations. The most widely used type of equipment currently requires the use of a cable to connect the probe and place it in the goaf. The equipment is easily damaged and has low detection accuracy. In addition, the device only uses a laser detector, which has very limited application scenarios. At the same time, the existing detection equipment does not have a fixed line function, and the probe is not stable during the detection process, resulting in large errors in data collection, affecting judgment during operations. In addition, because the data cables are exposed and easily damaged, and the equipment is large and inconvenient to carry, this type of equipment has not been widely promoted. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a replaceable three-dimensional data detection device that can realize the functions of straight line positioning and internal routing, has a simple structure, is easy to carry and assemble, and solves the problems of the current goaf detection equipment having a complex structure, inaccurate collected data, and high cost.

[0005] The technical solution of the utility model is as follows:

The bottom of motor 1 is connected to a carbon tube connector via a motor connector, and the carbon tube connector is connected to the carbon tube. The data cable of the detector is arranged inside the carbon tube.

[0007] A plurality of carbon tubes are provided, and the plurality of carbon tubes are linearly connected through two connecting sleeves.

[0008] One side of the connection of the two connecting sleeves is hinged, and the other side is provided with a convex wall. During use, the convex wall is fixedly connected by bolts.

[0009] The detection device includes a rotating connection shaft, a connecting plate, a detector fixing frame, a detector fixing plate and a detector. The rotating connection shaft is connected to the output shaft of the second motor. The rotating connection shaft is connected to the connecting plate, and the connecting plate is fixed to the outside of the detector fixing frame. Partition plates are provided on both side walls of the detector fixing frame; a detector is fixedly connected to the detector fixing plate, and the detector fixing plate is fixed between the partition plate and the bottom plate of the detector fixing frame.

[0010] Hollow shafts are left inside the carbon tube connector, the motor connector, and the first motor. The data cable of the detector enters the inside of the carbon tube through the hollow shaft.

[0011] The detector is a laser ranging radar, a sonar, a thermal imager or a micro camera.

[0012] The detector fixing plate is replaced according to the model of the detector.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. Through the cooperation of the first motor and the second motor, the present application can realize the rotation of the detector at any angle, and further realize the all-round detection in the gob area, and the data collection of the overall space in the gob area is more accurate.

[0015] 2. The present application realizes the connection of multiple carbon tubes through the connecting sleeve, and can realize the detection of gob areas with different depths; at the same time, through the connection of the carbon tube to the detection device, replacing the traditional cable connection of the detector, the detector can perform fixed-point detection, improving the accuracy of the acquired data.

[0016] 3. One end of the connecting sleeve of the present application is hinged, and the other end is fixedly connected during use, that is, when the axes of the two connecting sleeves are on the same straight line, the axes of the carbon tubes connected to the connecting sleeves are also on the same straight line. At this time, the connecting sleeve is fixed, so that the two carbon tubes form a straight line, thereby realizing the fixed straight line function.

[0017] 4. The hollow shaft design of the carbon tube connector, the motor connector, and the first motor of the present application realizes wiring inside the tube, protects the data cable with the carbon tube, and expands the applicable scenarios of the detector.

[0018] 5. The detector of the present application is fixed on the detector fixing plate, and the detector fixing plate is fixed on the detector fixing bracket.

The bottom of the motor connecting member 4 is connected to a carbon tube connecting member 3, and the carbon tube connecting member 3 is connected to a carbon tube 2; in this embodiment, through holes are provided on the outer wall of the carbon tube connecting member 3, and bolts passing through the through holes can realize the connection between the carbon tube connecting member 3, the carbon tube 2, and the motor connecting member 4; considering the different detection depth requirements in the mined-out area, multiple carbon tubes 2 are provided, and the multiple carbon tubes 2 are connected in a straight line through two connecting sleeves 1; in this embodiment, a row of through holes is provided on the barrel wall of the connecting sleeve 1, and a row of the same through holes is provided on the carbon tube 2, and bolts passing through the through holes on the connecting sleeve 1 and the carbon tube 2 realize the connection; one side of the connection between the two connecting sleeves 1 is hinged, and a convex wall 1.1 is provided on the other side. During use, the convex wall 1.1 is fixedly connected by bolts.

[0025] When two carbon tubes 2 are connected, when the axes of the two connecting sleeves 1 are on the same straight line after rotation, bolts are used to pass through the through holes on the convex wall 1.1 to realize fixation and prevent the connecting sleeve 1 from rotating. At this time, the connection parts of the two carbon tubes 2 through the connecting sleeve 1 are on a straight line, realizing the function of a fixed straight line.

[0026] The detection device 8 includes a rotating connection shaft 8.5, a connecting plate 8.4, a detector fixing frame 8.1, a detector fixing plate 8.2, and a detector 8.3. The rotating connection shaft 8.5 is connected to the output shaft of the second motor 7, and the rotating connection shaft 8.5 is connected to the connecting plate 8.4. Four through holes in a circumferential array are provided on both the connecting plate 8.4 and the rotating connection shaft 8.5, and screws are used to realize the connection with the second motor 7 through the through holes; the connecting plate 8.4 is fixed outside the detector fixing frame 8.1, and partition plates 8.6 are provided on both side walls of the detector fixing frame 8.1; a detector 8.3 is fixedly connected to the detector fixing plate 8.2, and the detector fixing plate 8.2 is fixed between the partition plate 8.6 and the bottom plate of the detector fixing frame 8.1; during the rotation of the second motor 7, the rotating connection shaft 8.5 is driven to rotate, and then the connecting plate 8.4, the detector fixing frame 8.1, and the detector 8.3 are driven to rotate.

[0027] The detector fixing plate 8.2 is replaced according to the model of the detector 8.3; in order to achieve the replaceability of the detector 8.3, detector fixing plates 8.2 can be equipped for each type of detector 8.3 according to the size information of different detectors 8.3.

When replacement is needed, directly remove the detector fixing plate 8.2 and replace it with a detector fixing plate 8.2 suitable for the replaced detector 8.3, and fix it on the detector fixing bracket 8.1.
