For example, the conveyor belt for transporting coal needs real-time monitoring, so the entire conveyor belt needs to be inspected. Generally, the inspection equipment needs to be pulled by a wire rope and move along a set track. For example, the wire rope is driven by an explosion-proof drive motor, and the inspection equipment moves accordingly. Various sensors on the inspection equipment are used to detect the operation and environmental data of the belt conveyor to understand its working conditions. However, in general traction devices, the track is a straight line and cannot meet the needs of curved inspection routes. Summary of the invention

[0029] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0030] refer to Figures 1 to 4 , Figure 1 is a schematic diagram of the structure of the inspection system in one embodiment of the present invention, Figure 2 for Figure 1 The partial enlarged schematic diagram I, Figure 3 for Figure 2 Schematic diagram of the structure of the middle guide wheel and guide wheel group, Figure 4 for Figure 2 A schematic diagram of the longitudinal section structure at the axis of the guide wheel in the inspection system. The guide wheel, guide wheel assembly, traction device and inspection system provided by the present invention will be described below in conjunction with the accompanying drawings.

[0031] The inspection system includes an inspection device 900 and a traction device. The traction device includes a track 100, a traction rope 200, a traction rope connector 850 and a plurality of guide wheel groups arranged along the track 100. The guide wheel group includes a first guide wheel 500a and a second guide wheel 500b. The guide wheel group is fixed on the track 100. The traction rope 200 extends along the track 100 and forms a closed loop by a round trip. The traction rope 200 passes through the guide channel m of the guide wheel group. One end of the traction rope connector 850 is fixed to the traction rope 200, and the other end extends along the radial direction of the traction rope 200. When the traction rope connector 850 moves with the traction rope 200, it can pass through the gap n between the top of the flange of the first guide wheel 500a and the second guide wheel 500b. The traction rope connector 850 pulls the walking wheel group to walk on the track. The walking wheel group is suspended with the inspection device 900. The above structure will be further described below.

[0032] like Figure 3 As shown, Figure 3 for Figure 2 Schematic diagram of the structure of the guide wheel and the guide wheel group. The first guide wheel 500a and the second guide wheel 500b constitute the guide wheel group, and the two have the same structure. Here, the first guide wheel 500a is used as an example for explanation. The first guide wheel 500a includes a wheel body, a first flange 510a and a second flange 520a arranged on the circumference of the wheel body, and a groove 530a between the two flanges. Among them, the height of the first flange 510a is greater than the height of the second flange 520a. Both flanges surround the wheel body and protrude radially. One side of the flange (observed in the longitudinal section view) is a part of the end face of the wheel body, and the other side is an arc surface, which constitutes a part of the groove 530a. The arc side surfaces of the two flanges jointly form the surface of the groove 530a. In this embodiment, the cross-sectional shape of the groove 530a is an arc, so it can form a circular guide channel m in cooperation with the groove 530b of the second guide wheel 500b. In some optional embodiments, the groove type of the groove can also be an inverted trapezoidal groove, that is, the groove bottom width is less than the width of the groove opening.

[0033] The axes of the first guide wheel 510a and the second guide wheel 510b are parallel, and the wheelbase of the two is slightly larger than the distance from the top surface of the first flange 510a to the axis (top surface radius), and the two end surfaces of the two are flush, and the groove 530a and the groove 530b face to face to form a guide channel m. There is a relatively small gap between the first flange 510a of the first guide wheel 500a and the first flange 510b of the second guide wheel 500b, and there is a larger distance between the top ends of the second flange 520a and the second flange 520b, thereby forming a gap n, and the distance of the gap n is smaller than the diameter of the traction rope 200.

[0034] In some optional embodiments, the axes of the first guide wheel 500a and the second guide wheel 500b may not be parallel, and may have an angle of, for example, 5 degrees, 20 degrees, or a value therebetween, while keeping the first flange 510a adjacent to the first flange 510b, and forming a gap between the second flange 520a and the second flange 520b. In this way, when the force direction of the traction rope 200 on the guide wheel group points to the track 100 along the symmetry plane of the first guide wheel 500a and the second guide wheel 500b, the guide wheel can withstand a certain radial force component. In this case, the flanges of the first guide wheel 500a and / or the second guide wheel 500b may be of equal height, and a gap may be formed between the second flange 520a and the second flange 520b by adjusting the angle of the axes of the first guide wheel 500a and the second guide wheel 500b. The guide wheel group is fixed on the track 100 through a bracket, and the traction rope 200 is constrained near the track 100.

[0035] The traction cable connector 850 can be connected to the traction cable 200 without interfering with the guide wheel assembly. The traction cable connector 850 includes a main connector and a transition plate. The main connector includes a main body 851, a clamp 852 and a sleeve 853. The clamp 852 and the sleeve 853 are arranged at both ends of the main body 851 to form the main connector as a whole. The main connector is hinged to the transition plate through the clamp 852. The main body 851 is a plate. In this embodiment, the clamp 852 is specifically a sleeve-shaped structure rolled at one end of the main body 851. The axes of the clamp 852 and the sleeve 853 and the plate surface of the main body 851 are parallel. One end of the transition plate has two forks, and the two forks are rolled into a cylindrical structure and the cylindrical structure is coaxial. The clamping member 852 of the traction cable connecting member 850 is located between the cylindrical structures formed by the bifurcation at one end of the transition plate and is coaxially connected to the cylindrical structure to form a hinge structure, and the hinge axis of the hinge structure is parallel to the traction cable 200. The hinge structure can be detachably connected to the transition plate in the form of bolts or pins. The other end of the transition plate is provided with a connecting shaft perpendicular to the plate surface, and is connected to the bracket of the walking wheel set through the connecting shaft. The sleeve 853 can be compressed under a certain external force, so as to be clamped on the first cable segment 210.

[0036] The main connecting member and the traction rope 200 can also be set to a detachable connection. For example, the sleeve 853 can also have a side opening, through which it is embraced on the first rope segment 210, and then the opening is closed and pressure is maintained by a hoop or bolt connection to fasten it to the first rope segment 210.

[0037] When the traction rope connector 850 moves with the traction rope 200 through the guide channel m between the first guide wheel 500a and the second guide wheel 500b, the sleeve 853 can directly pass through the guide channel m, and the main body 851 can pass through the gap n without interfering with the guide wheels.

[0038] The track 100 has an I-shaped cross section. The track 100 is composed of a plurality of track sections. Each track section is composed of two parallel horizontal plates and a vertical plate connecting the two horizontal plates. The vertical plate divides the space between the two horizontal plates into two parts. The track 100 is formed by connecting track section 1 101, track section 2 102 and track section 3 103 in series. Track section 2 102 is bent upward relative to track section 1 101, and track section 3 103 is bent to the left relative to track section 2 102. The upper surface of the horizontal plate located at the bottom of the track 100 is a supporting surface, and is divided into two parts by the vertical plate, namely the first track surface 110 and the second track surface 120. The first track surface 110 and the second track surface 120 can allow the inspection equipment 900 to walk. The two side surfaces of the vertical plate are the first guide surface 130 and the second guide surface 140, respectively. In some optional embodiments, the track 100 may also be in other shapes, such as a structure with a "T"-shaped cross section, that is, the track is composed of a horizontal plate and a vertical plate located below the horizontal plate, the upper surface of the horizontal plate is a support surface (track surface for walking); the vertical plate can also be used as a guide surface. For another example, the track 100 may also be a structure with a "⊥"-shaped cross section, that is, it is composed of a horizontal plate and a vertical plate located above the horizontal plate, the upper surface of the horizontal plate is a support surface and is divided into two track surfaces by the vertical plate, and the two side surfaces of the vertical plate can be used as guide surfaces.

[0039] The traction rope 200 extends back and forth along the track 100 to form a closed loop, and two sections extending in opposite directions are distributed on both sides of the vertical plate of the track 100, namely the first rope section 210 and the second rope section 220 shown in the figure, which are parallel in the horizontal direction. The first rope section 210 and the second rope section 220 can both be used to hang and pull the inspection equipment 900. The first rope section 210 of the traction rope 200 is arranged corresponding to the first rail surface 110 and the first guide surface 130 and has a predetermined distance between the two. The second rope section 220 is arranged corresponding to the second rail surface 120 and the second guide surface 140 and has a predetermined distance between the two.

[0040] There is a certain angle between the track section 2 102 and the track section 3 103, so multiple guide wheel groups are required to constrain the traction rope 200 near the first track surface 110 and the first guide surface 130, and at the same time, the movement of the traction rope connector 850 on the traction rope 200 cannot be affected. Since the track 100 is bent in the horizontal direction, the traction rope 200 needs to be constrained in the horizontal direction, but due to the setting of the guide wheel group bracket and the traction rope connector 850, the horizontally configured guide wheel (the guide wheel with the wheel axle perpendicular to the first track surface 110) needs to set the traction rope 200 between the guide wheel and the first guide surface 130, that is, there are obstacles near the traction rope 200 in all radial directions, which is not suitable for connecting the traction rope connector 850. In the present application, a guide wheel group consisting of two vertically configured guide wheels (the axle of which is perpendicular to the first guide surface 130) is used to constrain the traction rope 200. The guide channel m formed by the side walls of the grooves around the two guide wheels of the guide wheel group can restrain the traction rope 200, and the gap n can allow the traction rope connector 850 to pass through, which effectively solves the above-mentioned problem.

[0041] In some optional embodiments, the two flanges of the first guide wheel 500a have the same height, and the height of the second flange 520b in the second guide wheel 500b is smaller than the height of the first flange 510b, and a gap n can still be formed on one side of the guide channel m for the traction rope connector 850 to pass through.

[0042] The above structure is the composition of the traction device, which provides the basic carrier and connection basis for the traction inspection equipment. The first cable segment 210 and the second cable segment 220 of the traction cable 200 can be parallel in the horizontal direction, and cooperate with the support surface of the traction cable 200, so that the first cable segment 210 and the second cable segment 220 can be used as the connection basis for connecting the inspection equipment, providing the option of installing at different positions when connecting the inspection equipment, and can better adapt to the working conditions of the limited space in the underground tunnel. For example, when the position of one side of the first cable segment 210 is not suitable for connecting the inspection equipment, the inspection equipment can be connected to one side of the second cable segment 220. In addition, since the normal direction of the track support surface (rail surface) is generally vertical, the first cable segment 210 and the second cable segment 220 can be easily set to the same distance as the track support surface, so that the structure connecting the traction cable and the running wheel can adapt to the connection with the first cable segment 210 and the connection with the second cable segment 220 at the same time without changing.

[0043] The traveling wheel assembly can travel on the track 100 and is used to connect the traction rope 200 and the inspection device 900 .

[0044] refer to Figure 5In this embodiment, the running wheel assembly includes a first wheel assembly, a second wheel assembly 840, and a traction cable connector and a device connector respectively arranged on the first wheel assembly and the second wheel assembly 840. The traction cable connector 820 and the device connector 830 are connected to the first wheel assembly, and the traction cable connector 850 and the device connector 860 are connected to the first wheel assembly. The traction cable connector 850 is connected to the first cable segment 210, and the running wheel assembly can travel on the support surface of the track 100.

[0045] The structures of the first wheel group and the second wheel group 840 and the auxiliary structures connected thereto are the same, and the second wheel group 840, the traction rope connector 850 and the equipment connector 860 are taken as examples for description.

[0046] The second wheel group 840 includes a bracket 841, two load-bearing wheels 842 and a guide wheel 843. The bracket 841 is composed of a vertical plate and two horizontal plates perpendicular to the vertical plate. The width of the vertical plate is greater than the height. The two horizontal plates support the guide wheel 843. The two load-bearing wheels 842 are respectively arranged at both ends of the vertical plate in the horizontal direction, with the wheel axle horizontal and the wheel circumference tangent to the support surface of the track 100. The guide wheel 843 is hinged between the two horizontal plates, with the wheel axle vertically arranged and the wheel circumference tangent to the guide surface of the track 100.

[0047] In some optional embodiments, only the second wheel group 840, the traction cable connector 850 and the equipment connector 860 may be provided to connect the first cable segment 210 and the inspection device 900, or only the first wheel group, the traction cable connector 820 and the equipment connector 830 may be provided to connect the second cable segment 220 and the inspection device 900, which can be selected according to actual needs. When a set of running wheels is provided, two traction cable connectors may be provided on the running wheels, one of which is adapted to the first cable segment 210 and the other is adapted to the second cable segment 220, and one of them is selected to connect the traction cable 200 according to actual needs.

[0048] In some other optional embodiments, only one traction rope connecting member may be provided on the two wheel groups, and the connecting member is detachably connected to the wheel group and the traction rope 200, and can be connected between the first rope segment 210 and the second wheel group 840, or between the second rope segment 220 and the first wheel group according to actual needs.

[0049] In other optional embodiments, the support surface of the track 100 may include only one rail surface, and no guide surface may be provided. The wheel group does not have guide wheels, and only relies on the traction of the traction rope 200 to move and turn.

[0050] After the inspection equipment 900 is hung on the inspection equipment track device, it becomes the alley inspection system. The inspection equipment 900 integrates methane sensors, temperature sensors, carbon monoxide sensors, humidity sensors and distance sensors. When the inspection equipment 900 moves along the track device in the alley, it can obtain the operating status parameters of the alley and conveyor belt through the above sensors.

[0051] The track device, traction device and inspection system provided in the embodiments of the present invention are provided with transversely parallel traction ropes and horizontal support rail surfaces corresponding to the traction ropes, so that both traction ropes can be used to pull the inspection equipment, thereby enhancing its adaptability in the tunnel.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
