The guide wheel, the guide wheel set, the traction device and the inspection system provided by the invention are described in the following with reference to the attached drawings.

The inspection system comprises an inspection device 900 and a traction device, wherein the traction device comprises a rail 100, a traction cable 200, a traction cable connector 850 and a plurality of guide wheel sets arranged along the rail 100, and each guide wheel set comprises a first guide wheel 500a and a second guide wheel 500 b. The guide wheel set is fixed on the rail 100, the traction cable 200 extends along the rail 100 and makes a round trip to form a closed loop, the traction cable 200 passes through the guide channel m of the guide wheel set, one end of the traction cable connector 850 is fixed on the traction cable 200, the other end extends along the radial direction of the traction cable 200, and the traction cable connector 850 can pass through the gap n between the flange tops of the first guide wheel 500a and the second guide wheel 500b when moving along with the traction cable 200. The traction cable connecting piece 850 pulls the travelling wheel set to travel on the track, and the travelling wheel set is hung with the inspection equipment 900. The above structure will be further explained below.

As shown in fig. 3, fig. 3 is a schematic structural diagram of the guide wheel and the guide wheel set in fig. 2. The first guide wheel 500a and the second guide wheel 500b constitute a guide wheel set, and both have the same structure, and the first guide wheel 500a is taken as an example for description. The first guide wheel 500a includes a wheel body, a first flange 510a and a second flange 520a disposed on a circumferential surface of the wheel body, and a groove 530a between the two flanges. Wherein the height of the first flange 510a is greater than the height of the second flange 520 a. Both flanges are arranged around the wheel body and project radially, one side surface (viewed in longitudinal section) of the flange being part of the end surface of the wheel body, the other side surface being an arcuate surface forming part of the recess 530a, the arcuate side surfaces of the two flanges together forming a surface of the recess 530 a. In this embodiment, the cross-sectional shape of the groove 530a is a circular arc, so that a circular guide passage m can be formed in cooperation with the groove 530b of the second guide wheel 500 b. In some alternative embodiments, the groove profile of the groove may also be an inverted trapezoidal groove, i.e., the groove base width is less than the width of the groove opening.

The first guide wheel 510a and the second guide wheel 510b are parallel in axis, the distance between the axes is slightly larger than the distance from the top surface of the first flange 510a to the axis (radius of the top surface), the two end surfaces are flush, and the groove 530a and the groove 530b are matched in a face-to-face mode to form a guide channel m. The first flange 510a of the first guide wheel 500a has a relatively small gap from the first flange 510b of the second guide wheel 500b, and the second flange 520a has a large distance from the top end of the second flange 520b, thereby forming a gap n, the distance of which is smaller than the diameter of the traction cable 200.

In some alternative embodiments, the axes of the first guide wheel 500a and the second guide wheel 500b may also be non-parallel and may have an included angle of, for example, 5 degrees, 20 degrees, or a value therebetween, while maintaining the first flange 510a adjacent to the first flange 510b and the second flange 520a with a gap formed therebetween and the second flange 520 b. So configured, when the acting force direction of the traction cable 200 to the guide wheel set is directed to the rail 100 along the symmetry plane of the first guide wheel 500a and the second guide wheel 500b, the guide wheels can bear certain component force in the radial direction. In this case, the respective flanges of the first guide wheel 500a and/or the second guide wheel 500b may be equally high, and a gap may be formed between the second flange 520a and the second flange 520b by adjusting the angles of the axes of the first guide wheel 500a and the second guide wheel 500 b. The guide wheel set is fixed on the rail 100 through a bracket, and the traction cable 200 is restrained near the rail 100.

The pull cable attachment 850 can be attached to the pull cable 200 without interference from the guide wheel set. The pull cable connecting piece 850 comprises a main connecting piece and a transition plate 854, the main connecting piece comprises a main body 851, a tightening piece 853 and a sleeve 852, the tightening piece 853 and the sleeve 852 are arranged at two ends of the main body 851 to form the whole main connecting piece, and the main connecting piece is hinged with the transition plate 854 through the tightening piece 853. The main body 851 is a plate member, and in this embodiment, the fastening member 853 is a sleeve-shaped structure formed by rolling one end of the main body 851. The hoops 853 are parallel to the axis of the sleeve 852 and to the faces of the plates of the body 851. One end of the transition plate 854 has two branches, both of which are rolled into a cylindrical structure and the cylindrical structure is coaxial. The tightening member 853 of the traction cable connecting member 850 is positioned between the cylindrical structures formed by the branches at one end of the transition plate 854 and coaxially connected with the cylindrical structures to form a hinge structure, and a hinge shaft of the hinge structure is parallel to the traction cable 200. The hinge structure may be in the form of a bolt or pin to provide a removable connection with the transition plate 854. The other end of the transition plate 854 is provided with a connecting shaft perpendicular to the plate surface, and the connecting shaft is connected to the bracket of the walking wheel set. The sleeve 852 may be collapsed under some external force to tighten over the first cable segment 210.

The primary connector may also be configured to releasably engage the pull cable 200. for example, the sleeve 852 may have a side opening through which it is received over the first cable segment 210, and may be secured to the first cable segment 210 by a hoop or bolt connection that closes the opening and maintains pressure.

When the traction cable attachment 850 moves with the traction cable 200 through the guide passage m between the first guide wheel 500a and the second guide wheel 500b, the sleeve 852 may directly pass through the guide passage m and the body 851 may pass through the gap n without interfering with the guide wheels.

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 transverse plates and a vertical plate for connecting the two transverse plates, and the vertical plate divides the space between the two transverse plates into two parts. The track 100 is formed by connecting a first track section 101, a second track section 102 and a third track section 103 in series, wherein the second track section 102 is bent upwards relative to the first track section 101, and the third track section 103 is bent leftwards relative to the second track section 102. The upper surface of the horizontal plate located below in the track 100 is a supporting surface and is divided into two parts by a vertical plate, namely a first rail surface 110 and a second rail surface 120, and the first rail surface 110 and the second rail surface 120 can patrol and examine the walking of the equipment 900. The two sides of the riser are a first guide surface 130 and a second guide surface 140, respectively. In some alternative embodiments, the track 100 may have 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, and the upper surface of the horizontal plate is a supporting surface (a surface on which a rail travels); the riser may also serve as a guide surface. For another example, the rail 100 may have a "t" shaped cross section, that is, it is composed of a horizontal plate and a vertical plate above the horizontal plate, the upper surface of the horizontal plate is a supporting surface and is divided into two rail surfaces by the vertical plate, and two side surfaces of the vertical plate may be used as guide surfaces.

The cable 200 extends back and forth along the track 100 in a loop, and two segments extending in opposite directions are distributed on both sides of a vertical plate of the track 100, i.e., a first cable segment 210 and a second cable segment 220 are shown, which are parallel in the transverse direction. Both the first cable segment 210 and the second cable segment 220 may be used to hitch and tow the inspection device 900. The first cable segment 210 of the traction cable 200 is disposed corresponding to the first rail surface 110 and the first guide surface 130 with a predetermined distance therebetween. The second rope segment 220 is disposed corresponding to the second rail surface 120 and the second guide surface 140 with a predetermined distance therebetween, respectively.

There is an angle between second rail segment 102 and third rail segment 103, thus requiring multiple guide wheel sets to restrain the pull cable 200 near the first rail surface 110 and the first guide surface 130 without interfering with the movement of the pull cable attachment 850 on the pull cable 200. Since the rail 100 is bent in the horizontal direction, it is necessary to restrain the traction cable 200 in the horizontal direction, but it is limited to the arrangement of the guide wheel set bracket and the traction cable connector 850, and the use of a horizontally arranged guide wheel (a guide wheel whose axle is perpendicular to the first rail surface 110) requires the traction cable 200 to be arranged between the guide wheel and the first guide surface 130, i.e., there is a blockage near the traction cable 200 in all radial directions, which is not suitable for connecting the traction cable connector 850. In the application, the traction cable 200 is restrained by the guide wheel set consisting of two guide wheels which are vertically arranged (the wheel shaft is perpendicular to the guide wheels of the first guide surface 130), the guide channel m formed by the side walls of the grooves on the peripheries of the two guide wheels of the guide wheel set can restrain the traction cable 200, and meanwhile, the gap n can be used for the traction cable connecting piece 850 to pass through, so that the problem is well solved.

In some alternative embodiments, the height of the two flanges of the first guide wheel 500a is the same, and the height of the second flange 520b of the second guide wheel 500b is less than the height of the first flange 510b, so that a gap n can be formed on one side of the guide channel m for the traction cable connector 850 to pass through.

The structure provides a basic carrier and a connection foundation for the traction inspection equipment for the composition of the traction device. First cable section 210 and second cable section 220 of haulage cable 200 can be in horizontal parallelism, and the holding surface of cooperation haulage cable 200 for first cable section 210 and second cable section 220 all can be as the connection basis of connecting equipment of patrolling and examining, provide the selection of installing in different positions when connecting equipment of patrolling and examining, more can adapt to the limited operating mode in underworkings space. For example, when the side of the first cable section 210 is not properly positioned for attachment of routing inspection equipment, routing inspection equipment may be attached to the side of the second cable section 220. Also, since the normal direction of the rail support surface (rail surface) is generally vertical, the first and

second cable segments

210 and 220 can be easily set to the same distance from the rail support surface, so that the structure for coupling the traction cable and the road wheel can be adapted to the coupling with the first cable segment 210 and the second cable segment 220 at the same time without change.
