[0002] Track measurement vehicles are vehicles specially designed for track measurement, usually consisting of a locomotive and measuring instruments. They are usually equipped with high-precision sensors and measuring instruments, which can collect track data in real time during driving, including parameters such as height difference, curvature, and roadbed settlement. The use of track measurement vehicles can help operators discover and solve track problems in a timely manner, and improve track safety and operating efficiency.

[0003] The current measuring trolley needs to be manually controlled to move along the track, and automatic measurement cannot be achieved. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a monorail measuring trolley to solve the problems involved in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a monorail measuring trolley, comprising a frame, a top wheel arranged at the lower side of the top of the frame, and side wheels arranged at the inner sides of both ends of the frame, wherein the top wheel abuts against the top of the track, and the side wheels abut against the two sides of the track, and the top wheel and the side wheels on both sides are provided with more than two;

[0006] The top frame is provided with a prism positioning plate, the prism positioning plate is provided with a prism rod, the prism rod is provided with a total station prism head, and the prism positioning plate is provided with a detachable side push rod.

[0007] Furthermore,

[0008] There are two top wheels and four side wheels, and each top wheel cooperates with the two side wheels to clamp the track on the same vertical plane.

[0009] Furthermore, the frame includes a top frame and side frames connected to both ends of the top frame, the top frame and the side frames are vertically arranged, the top wheel is arranged on the lower side of the top frame, and the side wheels are arranged on the inner side of the side frame.

[0010] Furthermore, a top wheel frame is provided on the top frame, and a side wheel frame is provided on the side frame.

[0011] Furthermore, the top wheel is arranged on the top wheel frame, and the side wheels are arranged on the side wheel frames.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The top wheel and the side wheels of the utility model are in contact with the top and the side of the track respectively, so as to ensure that the trolley automatically moves forward along the track without manual control of the moving direction. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Embodiment 1:

[0020] Depend on Figure 1-2 As shown, a monorail measuring trolley includes a frame, a top wheel 1 arranged on the lower side of the top of the frame, and side wheels 2 arranged on the inner sides of both ends of the frame. The top wheel 1 abuts against the top of the track, and the side wheels 2 abut against the two sides of the track. The top wheel 1 and the side wheels 2 on both sides are provided with more than two. The measuring trolley is set as a groove structure. The top wheel 1 is on the surface of a single steel rail, which is convenient for pushing the trolley to walk balanced on the single steel rail. The side wheels are attached to the side of the steel rail. When the trolley walks horizontally, the wheel hub is stuck on the side of the steel rail, which plays a stabilizing role and avoids tilting during walking. The frame is provided with a prism positioning plate 3, and the prism positioning plate 3 is provided with a prism rod 4, which is perpendicular to the rail surface. The prism rod 4 is provided with a total station prism lens. The top of the prism rod 4 is 20 cm away from the top surface of the steel rail and 721.3 mm away from the center of the line. During measurement, they are set as height constants and offset constants respectively. The prism positioning plate 3 is provided with a detachable side push rod 5. The side push rod 5 can facilitate personnel to push the trolley on the sleeper, and the human body does not block the placed prism.

[0021] The frame includes a top frame 6 and side frames 7 connected to both ends of the top frame 6. The top frame 6 and the side frames 7 are vertically arranged. The top wheel 1 is arranged on the lower side of the top frame 6, and the side wheels 2 are arranged on the inner side of the side frames 7. A top wheel frame 8 is arranged on the top frame 6. A side wheel frame 9 is arranged on the side frame 7, and the side wheels 2 are arranged on the side wheel frame 9.

[0022] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
