[0040] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the utility model, are only part of the embodiments of the utility model, not all of the embodiments, and are not used to limit the utility model.

Figure 1 The structure diagram of the inspection device of the cable trough of the scraper conveyor of the fully-mechanized mining working face of the coal mine is shown, and the bearing panel 1 is arranged on the top of the inspection device, and at least one sensor 5 ( Figure 1 Not shown, Figure 2 In the example, a sensor 5 is shown. The carrying panel 1 can be expanded in area to meet the carrying requirements according to the types and numbers of the carried sensors 5. That is, when multiple types, several or even more than ten sensors 5 need to be carried, the carrying panel 1 can be expanded in area accordingly, including but not limited to extension in the length direction, extension in the width direction, extension in the diagonal direction, etc.
[0042] In addition, the expansion of the area of the bearing panel 1 needs to take into account the limitations of the space of the comprehensive mining working face and needs to be conducive to the movement of the inspection device.
[0043] The walking wheel 2 rides on the top of the coal baffle plate of the cable trough of the scraper conveyor of the fully-mechanized working face of the coal mine, and the walking wheel 2 passes through the housing ( Figure 2 ) is rigidly connected to the bearing panel 1 and is used to drive the overall movement of the inspection device. The number of the running wheels 2 is two or more, and the specific number is determined according to the size of the bearing panel 1. It can be understood that the longer the bearing panel 1 is, the more the number of the corresponding running wheels 2 is.
[0044] The support wheel 3 is rigidly connected to the bearing panel 1, and is used to prevent the inspection device from tipping over. The number of the support wheel 3 is one or more, and the specific number is determined by the number of the running wheels 2. Figure 1 As shown in the example, two traveling wheels 2 are correspondingly equipped with one supporting wheel 3 .
[0045] The push-pull rod 4 is rigidly connected to the bearing panel 1 and is used for an operator to manually drive the inspection device to move.
[0046] Reference Figure 2The schematic diagram of a preferred structure of a bearing panel 1 and a sensor 5 is shown. In order for the sensor 5 to collect data well, the preferred structure of the bearing panel 1 is that the position corresponding to the sensor 5 is hollowed out on the panel; the bearing panel 1 and the housing 323 of the sensor 5 are fixed by bolts, so that the sensor 5 is carried on the bearing panel 1. The types of sensors 5 include but are not limited to: geological logging devices, tilt sensors, cameras, gas concentration sensors, dust sensors, MEMS sensors, three-dimensional laser scanners, distance sensors, etc.
[0047] For the running wheel 2, the preferred driving modes include but are not limited to: manual drive, electric drive, hydraulic drive, pneumatic drive, etc. The preferred structure of the running wheel 2 is to be equipped with a damping device 21, referring to Figure 3 The damping device 21 is used to make the inspection device adapt to fully mechanized mining working faces with different inclination angles and prevent the inspection device from stalling and sliding down at a large inclination angle.
[0048] The housing is a square structure 22, the bottom of which is open, and the travel wheel 2 is arranged at the bottom of the square structure 22, so that the travel wheel 2 can ride on the top of the coal retaining plate of the cable trough of the scraper conveyor of the fully mechanized working face of the coal mine. The travel wheel 2 can be rigidly connected to the square structure 22 through the screw holes at the bottom of the side plate of the square structure 22 and the square structure 22 can be rigidly connected to the bearing panel 1 through the screw holes at the top of the square structure 22 and the bolts.
[0049] Preferably, the inner diameter width of the running wheel 2 is set to be larger than a preset width, and the preset width is not less than the jump width of the thickness of the connection of the coal retaining plate. For example, in general, the jump width of the thickness of the connection of the coal retaining plate ranges from 2 cm to 6 cm, and the inner diameter width of the running wheel 2 can be set to 6 cm, thereby ensuring the passability of the inspection device.
[0050] For the structure of the support wheel 3, refer to Figure 4 The support wheel 3 is a schematic diagram of the structure of the inspection device. The support wheel 3 is used to support the stability of the entire inspection device, and is also rigidly connected to the bearing panel 1. The support wheel 3 and the running wheel 2 together ensure the stable structure of the inspection device.
[0051] The support wheel 3 includes: a wheel, a fixed structure 31, and an elastic structure 32; the elastic structure 32 includes: a first elastic adjustment structure 321, a second elastic adjustment structure 322, an outer shell 323 and a cross bar 324; the elastic structure 32 is rigidly connected to the load-bearing panel 1 through the outer shell 323; for example: a screw hole is opened on the outer shell 323, and the outer shell 323 is rigidly connected to the load-bearing panel 1 through bolts.
[0052] The cross bar 324 is disposed between the first elastic adjustment structure 321 and the second elastic adjustment structure 322 , and the cross bar 324 can be elastically displaced as the positions of the first elastic adjustment structure 321 and the second elastic adjustment structure 322 are adjusted. Figure 4 The first and second elastic adjustment structures 322 are shown in the figure by taking three groups of elastic adjustment structures as an example, and their respective adjustment rods 325 can be elastically adjusted so that the position of the cross bar 324 can be elastically offset.
[0053] The top of the fixed structure 31 is provided with a screw hole, which is rigidly connected to the cross bar 324 by means of a bolt; preferably, the screw hole opened at the top of the fixed structure 31 is located at the geometric center of the top. The bottom of the fixed structure 31 is open, and the wheel is arranged at the bottom of the fixed structure 31; the wheel is rigidly connected to the fixed structure 31 by means of a screw hole at the bottom of the side plate of the fixed structure 31 by means of a bolt, so that the wheel changes the vertical distance between the wheel and the travel wheel 2 with the elastic displacement of the cross bar 324, so as to adapt to the width change of the cable trough of the scraper conveyor of the fully-mechanized working face of the coal mine, and improve the versatility of the inspection platform device.
[0054] A preferred connection position between the push-pull rod 4 and the load-bearing panel 1 is shown in FIG. Figure 1 As shown: the push-pull rod 4 is fixed at any of the front and rear positions of the load-bearing panel 1. The so-called front and rear positions refer to the forward and backward directions of the walking wheel 2. Fixing the push-pull rod 4 at this position facilitates the operator to manually drive the push-pull rod 4. If the push-pull rod 4 is fixed at any of the left and right positions of the load-bearing panel 1, it will make it difficult for the operator to manually drive the push-pull rod 4, and the left and right positions of the inspection device will be occupied.
[0055] Better, refer to Figure 5 As shown in the structural schematic diagram of the push-pull rod 4, the push-pull rod 4 can be fixed at any position in the front and rear positions of the bearing panel 1 through a universal joint 41, so that the operator can manually drive the push-pull rod 4 to push or pull the inspection device along the coal baffle plate of the comprehensive mining working face. The specific fixed position between the push-pull rod 4 and the bearing panel 1 is determined by whether it is convenient for the operator to operate.
[0056] Preferably, the push-pull rod 4 is configured as a telescopic rod, which can be freely extended and retracted to adjust the length. The specific telescopic adjustment length is determined according to the arm length of the operator to facilitate the operator to operate the inspection device.
[0057] It should be noted that the above Figure 1-Figure 5 The structure diagram of the inspection device for the cable trough of the scraper conveyor of the coal mine fully-mechanized working face and the structure of each component are only shown as examples, and it does not mean that the inspection device proposed in the utility model can only be composed of these components and structures. All other devices that can realize the corresponding functions of the above components or structures can be replaced, and they are not described one by one.
[0058] In summary, the inspection device for the cable trough of the scraper conveyor of the fully mechanized working face of a coal mine provided by the utility model comprises: a bearing panel 1, a walking wheel 2, a supporting wheel 3, a push-pull rod 4, and a sensor 5. The bearing panel 1 is arranged on the top of the inspection device, and at least one sensor 5 is carried on the bearing panel 1. The bearing panel 1 is expanded in area according to the type and number of the carried sensors 5 to meet the carrying requirements.

The number of the running wheels 2 is two or more, and the specific number is determined according to the size of the bearing panel 1.
[0060] The support wheel 3 is rigidly connected to the bearing panel 1, and the support wheel 3 is used to prevent the inspection device from tipping over left and right. The number of the support wheel 3 is one or more, and the specific number is determined by the number of the running wheels 2. The push-pull rod 4 is rigidly connected to the bearing panel 1, and is used for the operator to manually drive the inspection device.
