Description

Technical Field

[0001] The present invention relates to the technical field of track detection, and in particular to an intelligent track detection trolley. Background Art

[0002] With the development of high-speed railways and heavy-load railways, the occurrence and development of uneven rail welding joints, periodic unevenness of rail top surfaces and abnormal wear of rail profiles have become increasingly prominent, resulting in abnormal wheel-rail contact, increased additional dynamic load on tracks, and damage to rail vehicle components, which in turn leads to an increase in track maintenance costs and a significant decrease in train running stability and comfort indicators.

[0003] During the railway construction phase, after the railway track is laid, the absolute and relative positions of the track need to be tested, and the positions that do not meet the design requirements need to be adjusted to ensure safe and comfortable operation of the train. During the long-term operation of the railway, the track will change due to long-term wear and tear, roadbed settlement, loose fasteners, etc., causing the absolute and relative states of the local positions of the track to change. These changes will seriously affect the safety and comfort of train operation, and these improvements must be tested and adjusted. The track gauge is one of the important test objects.

[0004] In recent years, rail repair technology has developed accordingly. Rail grinding and milling have evolved from introduction, digestion, and testing to large-scale application and have become the norm for daily maintenance. The measurement technology and evaluation technology of the required rail technical parameters have also developed accordingly. Rail profile detection has developed from manual point-type side grinding and vertical grinding detection to static rail profile electronic detection. At present, the detection trolleys for track detection are mostly assembled or integrated, with complex structures and cumbersome assembly, which are not conducive to carrying and handling, so there are certain limitations in use.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0033] According to an embodiment of the present invention, an intelligent track detection vehicle is provided.

[0034] like Figure 1-Figure 8 As shown, the intelligent track inspection trolley according to an embodiment of the present invention comprises a base 1, and a steering mechanism 2 is symmetrically provided on both sides of the base 1, and a support arm 3 is connected to the steering mechanism 2, and a moving wheel 4 is connected to one end of the support arm 3, and a limiting wheel 5 is provided below the support arm 3 and on one side of the moving wheel 4, wherein;

[0035] The steering mechanism 2 includes a steering seat 6 located in the base 1, a roller 7 is movably inserted in the steering seat 6, one end of the roller 7 is connected to a steering wheel 8, a plurality of limit grooves 9 are provided on the steering wheel 8, and the other end of the roller 7 passes through the steering seat 6 and is connected to one end of the support arm 3, a through groove 10 is provided in the steering seat 6, a limit rod 11 is provided in the through groove 10, one end of the limit rod 11 is adapted to the limit groove 9, and the limit rod 11 is located in the limit groove 9 and is sleeved with a spring 12, and the two sides of the spring 12 are respectively against the limit rod 11 and the through groove 10.

[0036] There are at least two groups of steering mechanisms 2 on the same side of the base 1 , and a handle 13 is provided on one side of the base 1 and between the steering mechanisms 2 .

[0037] A roller 14 is further provided on one side of the base 1 , and a placement frame 15 is provided on the roller 14 .

[0038] Wherein, a movable shaft is inserted into the moving wheel 4 , and the movable shaft is connected to the supporting arm 3 .

[0039] There are at least two groups of the limiting wheels 5 , and the limiting wheels 5 and the moving wheels 4 are arranged at 90°.

[0040] Among them, one end of the limiting rod 11 passes through the limiting groove 9 and is provided with a grip.

[0041] A fender 16 is provided at one end of the support arm 3 and located on one side of the moving wheel 4 .

[0042] With the help of the above technical solution, by manually pulling the limit rod 11 and manually moving the support arm 3, the support arm 3 cooperates with the roller 7 to rotate, so that the steering wheel 8 is linked to drive the limit slot 9 to rotate, and the limit rod 11 is fixed under the action of the spring 12 to realize the contraction and expansion of the support arm 3. It is placed on the track through the moving wheel 4 and the limit wheel 5 to run smoothly, realizing an integrated assembly. It is not only easy to contract and expand, but also has good stability, is easy to carry and carry, has a wide range of applications, and has strong adaptability.

[0043] In addition, specific Figure 5-Figure 8 As shown, for the above-mentioned steering mechanism 2, two groups of limiting grooves 9 are provided on its steering wheel 8, one group of limiting grooves 9 cooperates with limiting rods 11 for expansion and fixing, and the other group of limiting grooves 9 cooperates with limiting rods 11 for contraction and fixing. When in use, the through groove 10 is a convex structure, and its spring 12 is assembled in the through groove 10, and the limiting rod 11 penetrates the spring 12 and cooperates with one group of limiting grooves 9 for contraction and fixing, and the limiting rod 11 is a T-shaped rod, which is stably fixed under the action of the spring 12. When the limiting rod 11 is manually pulled outward, One end of the limit rod 11 is disengaged from the limit slot 9, and the support arm 3 is rotated to link the steering wheel 8. When the other set of limit slots 9 is rotated to the matching position of the through slot 10, the limit rod 11 slides inward under the action of the spring 12, so that one end of the limit rod 11 is fixed to the limit slot 9 at this time, so that the support arm 3 can be unfolded and locked stably. The unfolded intelligent track detection trolley is placed on the track by manually taking the handle 13, and it slides in contact with the track under the action of the moving wheel 4 and the limit wheel 5, and has high stability.

[0045] In addition, when in use, a mounting hole is opened in the center of the base 1, and a total station is assembled through the mounting hole to detect the track. A battery can be assembled in the base 1 to power the total station.

[0046] For the above-mentioned total station, that is, the total station type electronic distance meter, it is a high-tech measuring instrument integrating optics, machinery and electricity. It is a surveying and mapping instrument system that integrates the measurement functions of horizontal angle, vertical angle, distance, slant distance, horizontal distance and height difference. Compared with the optical theodolite, the electronic theodolite replaces the optical degree plate with a photoelectric scanning degree plate, and replaces the manual optical micrometer reading with automatic recording and display of readings, which simplifies the angle measurement operation and avoids the occurrence of reading errors. Because it can complete all the measurement work on the survey station by setting up the instrument once, it is called a total station. It is widely used in precision engineering measurement or deformation monitoring fields such as large-scale ground buildings and underground tunnel construction.

It is placed on the track through the moving wheel 4 and the limit wheel 5 to run smoothly, realizing an integrated assembly. It is not only easy to contract and expand, but also has good stability, is easy to carry and carry, has a wide range of applications, and has strong adaptability.
