Example 1

Referring to fig. 1, 2, 3 and 4, the wheel track system of a rail-mounted inspection vehicle in embodiment 1 includes two sets of wheel track assemblies, which are respectively and symmetrically connected to the left and right sides of a frame (not shown) of the inspection vehicle and are used for being correspondingly connected to rails (not shown) parallel to the left and right sides of a rail; the wheel-track assembly comprises a bearing wheel 10 which is received on the corresponding side rail in a rolling way, a first wheel seat 20 which is rotationally connected with the bearing wheel 10, an elastic part, a limiting wheel 50 and a second wheel seat 60 which is rotationally connected with the limiting wheel 50; the second wheel seat 60 is connected with the first wheel seat 20 in a sliding manner through a sliding structure, so that the second wheel seats 60 on two sides can move towards or away from each other;

the limiting wheels 50 on the two sides respectively roll and abut against the opposite side parts of the rail bars on the left side and the right side, and the elastic piece applies elastic force to the second wheel seat 60, so that the second wheel seats 60 on the two sides have the tendency of moving towards each other;

or, the limiting wheels 50 on both sides respectively roll and abut against the opposite side portions of the rail bars on both sides, and the elastic member applies elastic force to the second wheel seat 60, so that the second wheel seats 60 on both sides have a tendency to move back to back.

The inspection vehicle is mainly supported on the track by the bearing wheel 10, and the limit wheel 50 is driven by the elastic part to clamp the rail bars on two sides all the time in the driving process of the inspection vehicle, so that the problem that the existing wheel-rail system is easy to have derailment accidents when passing through the track in a space torsion form due to lack of a limit structure is solved. Meanwhile, since the limiting wheels 50 on both sides can move toward or away from each other, even if the track gauge of the rail on both sides changes within a certain range, the limiting wheels 50 can still firmly act on the rail on the corresponding side.

In addition, referring to fig. 1 again, in the embodiment 1, the two side limiting wheels 50 are specifically arranged in the following manner: the limiting wheels 50 on both sides respectively roll and abut against the opposite sides of the rail bars on the left and right sides, and the elastic member applies elastic force to the second wheel seat 60, so that the second wheel seats 60 on both sides have a tendency of moving towards each other. This arrangement is more reliable than an arrangement in which two spacing wheels 50 are disposed between the rails on either side.

Meanwhile, in the design process of the track, we find that: to meet the requirement that the track has a stroke to cover the bridge member, part of the sections in the track can be in a nearly vertically extending form, and at the moment, if the center of gravity of the inspection vehicle changes, the workshop is easy to tip backwards, and derailment accidents occur; therefore, as a preferred embodiment, in this embodiment 1, each set of the wheel-rail assemblies further includes a clasping wheel 80 rotatably connected to the first wheel seat 20, the clasping wheel 80 and the load-bearing wheel 10 are respectively disposed at two opposite sides of the rail, and a gap between the clasping wheel 80 and the load-bearing wheel 10 forms a clamping gap 30 for the rail on the corresponding side to pass through.

With the use of the hug wheels 80, when the inspection vehicle travels over these near vertical segments, the load bearing wheels 10 lose contact with the rail even if they tip backwards due to a change in the center of gravity. The hug wheel 80 can also continue to contact the rail by means of the take-over bearing wheel 10 so that the wheel-rail system will not derail in the face of an accident in which the inspection vehicle tips backwards. The clasping wheels 80 are matched with the limiting wheels 50 and the bearing wheels 10, so that a track and an inspection workshop are realized, meanwhile, the upper direction and the lower direction of the track and the left and right directions are roughly limited, and the safety of the whole system is effectively improved.

In this embodiment 1, the number of the rails is two, and the rails are respectively disposed on the left and right sides and extend in parallel, and the vehicle frame is correspondingly mounted on the rails on the left and right sides through the wheel rail assemblies on the two sides. The rail has a circular cross section, which is a circular steel pipe.

In addition, it is understood that: the clamping gap 30 formed by the gap between the corresponding side clasping wheel 80 and the bearing wheel 10 can be consistent with the distance between the upper and lower opposite side parts of the rail bar or can be kept with the gap between the opposite side parts of the upper rail bar, and the two modes can avoid the detection vehicle from accidentally tipping when facing the approximately vertical rail.

In addition, in order to meet the requirement of completely covering the exterior of the bridge member, the rail is often in a shape that the rail bars on both sides have a certain height difference when the rail falls on a section, and at this time, if the technical scheme that the clamping gap 30 is consistent with the distance between the upper and lower opposite side parts of the rail bar is adopted, the wheel rail system is easily blocked with the rail bar.

Therefore, as a preferred embodiment, in the embodiment 1, the size of the clamping gap 30 is larger than the size of the space between the two opposite sides of the rail for rolling contact with the clasping wheel 80 and the bearing wheel 10, respectively, i.e. when the rail penetrates between the clasping wheel 80 and the bearing wheel 10 and supports the bearing wheel 10, the gap is left between the rail and the clasping wheel 80; this is provided mainly for improving the passing performance of the wheel rail system when the left and right rail bars have a certain height difference facing the space torsion rail bar or the like.

More specifically, referring to fig. 4, in this embodiment 1, the sliding structure includes a sliding rail 71 disposed on the first wheel seat 20, and a sliding block 72 slidably engaged with the sliding rail 71 and fixedly connected to the second wheel seat 60, and the sliding rail 71 and the sliding block 72 engaged with each other as the sliding mechanism have the advantages of low implementation cost and reliable structure, and it can be understood that the second wheel seats 60 disposed on the left and right sides can move toward or away from each other, so that the specific extending direction of the sliding rail 71 is along the left and right directions.

Meanwhile, in this embodiment 1, the sliding structure includes a sliding rod 73 fixedly connected to the second wheel seat 60, and a sliding seat 74 penetrated by the sliding rod 73 and slidably engaged with the sliding rod 73, where the sliding seat 74 is fixedly connected to the first wheel seat 20. Similar to the above description, it can be understood that the specific extending direction of the sliding rod 73 is in the left-right direction since the second wheel holders 60 disposed at the left and right sides can be moved toward and away from each other.

As long as the slide rail 71 and the slide block 72 are selected, or any one of the slide rod 73 and the slide seat 74 is used as a slide structure, the function that the second wheel seats 60 on the left and right sides can move toward or away from each other can be realized, and in order to improve the slide stability, the slide structure in this embodiment 1 simultaneously includes the slide rail 71, the slide block 72, and the slide seat 74 of the slide rod 73 as described above. In addition, in this embodiment 1, a support plate 75 is disposed between the sliding seat 74 and the first wheel seat 20, and the support plate 75 is welded to the sliding seat 74 and the first wheel seat 20, respectively, so as to fixedly connect the sliding seat 74 and the first wheel seat 20.

More specifically, in this embodiment 1, regarding the structure that realizes the trend that the elastic member drives the second wheel seats 60 on the two sides to move towards each other, specifically, the structure includes: the sliding rods 73 on both sides are formed with a stop flange 76 at one end close to each other, the elastic member is sleeved on the sliding rod 73, and both ends of the elastic member are respectively abutted against the stop flange 76 and the sliding seat 74. The resilient member is embodied as a compression spring 40. It will be appreciated that, since the two ends of the compression spring 40 act on the abutment flange 76 and the slide seat 74, respectively, the abutment flange 76, the compression spring 40 and the slide seat 74 are arranged in this order along the side of the slide bar 73 from the end close to each other to the end away from each other.

Referring to fig. 2, in the embodiment 1, the first wheel seat 20 is rotatably connected with the bearing wheel axle 11 and the clasping wheel axle 81 to respectively and coaxially penetrate into the bearing wheel 10 and the clasping wheel 80, and is correspondingly and fixedly connected to realize the rotational connection between the bearing wheel 10, the clasping wheel 80 and the first wheel seat 20;

similarly, referring to fig. 3, in the embodiment 1, the second wheel seat 60 is rotatably connected with a limiting wheel shaft 51, and the limiting wheel shaft 51 coaxially penetrates through the limiting wheel 50 and is fixedly connected with each other, so as to realize the rotatable connection between the limiting wheel 50 and the second wheel seat 60.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
