Description

Technical Field

[0001] This utility model relates to the field of track inspection equipment technology, specifically a track flaw detection device for railway engineering. Background Technology

[0002] Track quality has a direct impact on the operation of rail vehicles on the track. Traditionally, a rail trolley is used to conduct all-round inspection of the track. The rail trolley is equipped with a variety of sensors that can accurately detect various parameters of the track.

[0003] Existing railcars include a base plate with a traveling assembly and various sensors mounted on the base plate. Given that the track has a left rail and a right rail, to ensure the stability of the railcar's movement, the left traveling assembly and the right traveling assembly are usually mounted on the base plate simultaneously. When using the railcar, the base plate with the traveling assembly is placed on the track by a crane or by multiple people carrying it, so that the left traveling assembly and the right traveling assembly can be attached to the left rail and the right rail respectively.

[0004] Although the above-described method allows for the installation of the track trolley, the simultaneous placement of the left and right travel components on the base plate results in a significant weight of the entire base plate. This necessitates the use of a crane or the coordinated efforts of multiple personnel to install the base plate onto the rails, causing operational inconvenience. This is particularly problematic when inspecting a short section of track, as it becomes impossible for a single person to operate the track trolley. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a track flaw detection device for railway engineering, so as to solve the technical problem in the background art that the existing track trolley is inconvenient to operate and cannot be operated by one person.

[0006] The present invention provides a track flaw detection device for railway engineering, the detection device being used to detect tracks, the tracks comprising two rails;

[0007] The detection device includes two traveling components and a bracket detachably connected between the two traveling components. The two traveling components are respectively used to attach to the two steel rails, and the bracket enables the two traveling components to move synchronously relative to the two steel rails.

[0008] Both of the aforementioned walking components include at least one limiting hole on the support base plate, and the bracket is provided with at least one limiting post opposite to the limiting hole. The limiting post is used to extend into the limiting hole to restrict the movement direction of the bracket.

[0009] Furthermore, the detection device also includes a flaw detector with a probe, the flaw detector being mounted on the supporting base plate, and the probe being mounted below the supporting base plate and directly facing the rail.

[0010] Furthermore, the support base plate is also provided with a fixing rod, and the bracket is also provided with a hole that mates with the fixing rod, as well as a fixing member that is screwed to the fixing rod.

[0011] Furthermore, the support base plate is provided with a plurality of limiting holes, and the plurality of limiting holes are arranged circumferentially with the center of the fixing rod as the origin;

[0012] The bracket is provided with multiple limiting posts, and the multiple limiting posts are arranged circumferentially with the center of the hole as the origin;

[0013] Each of the limiting holes is respectively arranged opposite to each of the limiting posts.

[0014] Furthermore, the size of the end of the limiting hole near the limiting post gradually changes from large to small, and the size of the end of the limiting post near the limiting hole gradually changes from small to large.

[0015] Furthermore, the walking assembly also includes a support column and a walking wheel rotatably connected to the support column, the walking wheel being connected to the support base plate via the support column.

[0016] Furthermore, the walking wheel includes two wheel bodies and a rotating shaft disposed between the two wheel bodies, the rotating shaft being connected to the support column;

[0017] The length of the rotating shaft is equal to the width of the rail, such that when the traveling wheel is attached to the rail, the rotating shaft is in contact with the rail and the two wheels are respectively attached to the opposite edges of the rail.

[0018] Furthermore, the bracket is also equipped with a push rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In this utility model of a railway engineering track flaw detection device, the use of two traveling components and a bracket detachably connected between the two traveling components allows for easy operation. During operation, the two traveling components are manually placed sequentially on two rails, and then connected by the bracket. This ensures that when the bracket is pushed, the two traveling components move synchronously on their respective rails, simplifying operation and allowing one person to operate the detection device. This solves the problem of inconvenient operation and the inability for one person to operate the track trolley in existing technologies. Furthermore, limit holes are provided on the support base plate of the traveling components, and limit posts corresponding to the limit holes are provided on the bracket. The limit posts and limit holes restrict the lateral movement of the bracket, ensuring that the two traveling components move synchronously when the bracket moves laterally.

Detailed Implementation

[0025] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0026] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Please see Figure 1-3 The image shows a track flaw detection device for railway engineering in one embodiment of the present invention. The detection device 100 is used to detect the track, which includes two rails 200. It should be noted that the two rails 200 are the left rail 200 and the right rail 200.

[0029] To address the problem of inconvenient operation of existing track trolleys, which cannot be operated by a single person, in this embodiment, the detection device 100 includes two traveling components 110 and a bracket 120 detachably connected between the two traveling components 110. The two traveling components 110 are respectively used to connect to two steel rails 200, and the bracket 120 enables the two traveling components 110 to move synchronously relative to the two steel rails 200. It should be noted that the two traveling components 110 can be a left traveling component 110 and a right traveling component 110.

[0030] Both walking components 110 include at least one limiting hole 112 provided on the support base plate 111, and the bracket 120 is provided with at least one limiting post 121 opposite to the limiting hole 112. The limiting post 121 is used to extend into the limiting hole 112 to limit the movement direction of the bracket 120.

[0031] In practical implementation, the two walking components 110 are manually connected sequentially to the two steel rails 200, and then the two walking components 110 are connected by the bracket 120. This allows the two walking components 110 to move synchronously on the corresponding steel rails 200 when the bracket 120 is pushed, thus simplifying the operation and enabling one person to operate the detection device 100. This solves the problem of inconvenient operation and inability for one person to operate the track trolley in the prior art. Furthermore, a limit hole 112 is provided on the support base plate 111 of the walking component 110, and a limit post 121 corresponding to the limit hole 112 is provided on the bracket 120. The limit post 121 and the limit hole 112 can restrict the lateral movement of the bracket 120, ensuring that the two walking components 110 can move synchronously when the bracket 120 moves laterally.

[0032] Specifically, to facilitate the inspection of the rail 200, in this embodiment, the inspection device 100 further includes a flaw detector 130 with a probe 131. The flaw detector 130 is disposed on the support base plate 111, and the probe 131 is disposed below the support base plate 111 and directly facing the rail 200. It should be noted that the flaw detector 130 can be an ultrasonic flaw detector 130, which can detect cracks and defects in the rail 200. It should also be noted that the flaw detector 130 is not limited to the ultrasonic flaw detector 130 shown in this example, but can also be other types of flaw detectors 130. Since the flaw detector 130 is conventional prior art in this field, it will not be specifically described.

[0033] In addition, to ensure the stability of the connection between the bracket 120 and the two traveling components 110, in some preferred embodiments, the support base plate 111 of the two traveling components 110 is also provided with a fixing rod 113, and the bracket 120 is also provided with a hole 122 that mates with the fixing rod 113, and a fixing member 123 that is screwed to the fixing rod 113. That is to say, in this example, the lateral movement of the bracket 120 can be restricted by the limiting post 121 and the limiting hole 112, and the longitudinal movement of the bracket 120 can be restricted by the fixing rod 113 and the fixing member 123, thereby ensuring the stability of the connection between the bracket 120 and the support base plate 111 in multiple directions. It should be noted that the fixing member 123 and the fixing rod 113 shown in this embodiment can be a screw and a nut that are threaded to the screw in the prior art.

[0034] Furthermore, the support base plate 111 is provided with a plurality of limiting holes 112, and the plurality of limiting holes 112 are arranged circumferentially with the center of the fixing rod 113 as the origin; the bracket 120 is provided with a plurality of limiting posts 121, and the plurality of limiting posts 121 are arranged circumferentially with the center of the hole 122 as the origin. Each limiting hole 112 is respectively arranged opposite to each limiting post 121. The arrangement of the plurality of limiting posts 121 and limiting holes 112 further ensures the stability of the bracket 120 installed on the support base plate 111.

[0035] In some preferred embodiments, to facilitate the assembly of the bracket 120 with the support base plate 111, the end size of the limiting hole 112 near the limiting post 121 gradually changes from large to small, and the end size of the limiting post 121 near the limiting hole 112 gradually changes from small to large. Specifically, the limiting hole 112 and the limiting post 121 can adopt a mutually cooperating conical structure.

[0036] In addition, the walking assembly 110 also includes a support column 114 and a walking wheel 115 rotatably connected to the support column 114. The walking wheel 115 is connected to the support base plate 111 through the support column 114. Specifically, the walking wheel 115 includes two wheel bodies 1151 and a rotating shaft 1152 disposed between the two wheel bodies 1151. The rotating shaft 1152 is connected to the support column 114. The length of the rotating shaft 1152 is equal to the width of the rail 200, so that when the walking wheel 115 overlaps the rail 200, the rotating shaft 1152 fits against the rail 200 and the two wheel bodies 1151 overlap the opposite two edges of the rail 200. In other words, by using the fact that the length of the rotating shaft 1152 is equal to the width of the rail 200, when the walking assembly 110 is overlapped, the two wheel bodies 1151 can be respectively engaged with the two sides of the rail 200, ensuring the stability of the walking assembly 110 during installation.

[0037] In addition, the support 120 is also equipped with a push rod, which can be used to assist the operator in dragging the support 120.

[0038] In summary, the track flaw detection device for railway engineering according to one embodiment of this utility model has at least the following advantages compared to existing track trolleys:

[0039] In the railway engineering track flaw detection device of this utility model, the two walking components 110 and the bracket 120 detachably connected between the two walking components 110 are arranged so that during operation, the two walking components 110 are manually placed on the two rails 200 in sequence, and then the bracket 120 is used to connect the two walking components 110. When the bracket 120 is pushed, the two walking components 110 move synchronously on the corresponding rails 200, thereby achieving simple operation and enabling one person to operate the detection device 100. This solves the problem of inconvenient operation and inability for one person to operate the track trolley in the prior art. Furthermore, the support base plate 111 of the walking component 110 is provided with a limiting hole 112, and the bracket 120 is provided with a limiting post 121 opposite to the limiting hole 112. The limiting post 121 and the limiting hole 112 can restrict the lateral movement of the bracket 120, ensuring that the two walking components 110 can move synchronously when the bracket 120 moves laterally.
