[0001] The utility model relates to the technical field of measuring equipment, in particular to a track flatness detection device for a rail vehicle used in building construction. Background Technique

[0002] Rail vehicles are the main transportation tools for construction departments such as infrastructure construction. Rail vehicles are divided into two types: heavy and light. Those that can be withdrawn from the line by the passengers are called light rail vehicles; those that cannot be withdrawn from the line by the passengers are called heavy rails.

[0003] In building construction, when it is necessary to transport some goods or building materials, rail vehicles are needed. Using rail vehicles to transport goods or building materials can reduce the bumps during transportation and make transportation more convenient. After the railway tracks are laid, they need to be tested for horizontality and inclination before they can be accepted. The traditional detection method is to vertically measure the edge of the railway track with a handheld measuring ruler, which has low measurement accuracy and slow measurement speed. In view of this, a track flatness detection device for a rail vehicle used in building construction is proposed. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-3 , the present utility model provides a new technical solution: a track flatness detection device for a rail vehicle in construction, including a flatness detection device body 1. Two chutes 2 are opened on the lower surface of the flatness detection device body 1, and a groove 3 is opened on the lower surface of the flatness detection device body 1;

[0025] A testing mechanism is arranged inside the flatness detection device body 1 and is used for detecting the flatness of railway tracks. The testing mechanism includes an H-shaped plate 4, and the H-shaped plate 4 is fixedly installed in the inner wall of the flatness detection device body 1.

[0026] A fixing mechanism is arranged inside the flatness detection device body 1 and is used for fixing the flatness detection device body 1 for subsequent detection. The fixing mechanism includes two hydraulic devices 11, and the two hydraulic devices 11 are respectively fixedly installed on the opposite surfaces of the two vertical plates of the H-shaped plate 4.

[0027] Furthermore, the testing mechanism further includes eight springs 5 and a fixing plate 6. The eight springs 5 are respectively fixedly installed on the lower surface of the cross plate of the H-shaped plate 4, and the fixing plate 6 is fixedly installed at the lower ends of the eight springs 5.

[0028] Furthermore, the testing mechanism further includes a fixing block 7 and a first positioning wheel 8. The fixing block 7 is fixedly sleeved on the inner surface of the fixing plate 6, and the first positioning wheel 8 is arranged on the lower surface of the fixing block 7.

[0029] Furthermore, the testing mechanism further includes a fixing column 9 and a scale 10. The fixing column 9 is fixedly installed on the upper surface of the fixing block 7, and the upper end of the fixing column 9 slidably penetrates through the upper surface of the flatness detection device body 1. The scale 10 is arranged on the outer surface of the fixing column 9.

[0030] Furthermore, the fixing mechanism further includes two hydraulic rods 12 and two L-shaped plates 13. The two hydraulic rods 12 are respectively slidably sleeved on the inner surfaces of the two hydraulic devices 11, and the two L-shaped plates 13 are respectively fixedly installed at the opposite ends of the two hydraulic rods 12.

[0031] Further, the fixing mechanism further includes two second positioning wheels 14, and the two second positioning wheels 14 are arranged on the opposite surfaces of the horizontal plates of the two L-shaped plates 13. When the railway track flatness detection device for construction vehicles is in use, by placing the first positioning wheel 8 on the surface of the railway track, at this time, by starting the two hydraulic devices 11, the two hydraulic devices 11 apply a pulling force towards the opposite surface to the two hydraulic rods 12 slidably sleeved on the inner surface during operation, so that they move towards the opposite surface. At the same time, the two hydraulic rods 12 apply a pulling force towards the opposite surface to the two L-shaped plates 13 fixedly installed at the opposite ends, so that they slide leftward towards the opposite surface in the two chutes 2. At the same time, the two L-shaped plates 13 drive the two second positioning wheels 14 arranged on the opposite surfaces of the horizontal plates to fit into the grooves on both sides of the railway track, completing the positioning. At this time, the positioning of the flatness detection device body 1 is completed. At this time, by pushing the flatness detection device body 1 to slide on the railway track surface and observing the scale 10 arranged on the fixed column 9, when passing through an uneven area, the first positioning wheel 8 will apply an upward thrust to the fixed block 7 arranged on the upper surface. At the same time, the fixed block 7 drives the fixing plate 6 fixedly sleeved on the outer surface to move upward. The fixing plate 6 applies a pressure to the eight springs 5 fixedly installed on the upper surface, causing them to contract. At the same time, the fixed block 7 applies an upward thrust to the fixed column 9 fixedly installed on the upper surface, causing it to move upward. At this time, the scale arranged on the fixed column 9 can be read. When the scale becomes smaller, it indicates that it is a high protrusion here. When a low-lying railway track is detected, the springs 5 expand due to their own elastic potential energy. The springs 5 apply a downward thrust to the fixing plate 6 fixedly installed on the lower surface. At the same time, the fixing plate 6 drives the fixed block 7 fixedly sleeved on the inner surface to move downward. The fixed block 7 applies a downward thrust to the first positioning wheel 8 arranged on the lower surface, causing it to move downward and fit the slide rail. At the same time, the fixed block 7 drives the fixed column 9 fixedly installed on the upper surface to move downward. At this time, the scale arranged on the surface of the fixed column 9 is read. When the reading becomes larger, it indicates that it is a low-lying area here. The railway track flatness detection device for construction vehicles can detect the flatness of the railway track by observing the scale arranged on the fixed column of the flatness detection device body 1. When the scale becomes larger, it indicates that the railway track is low-lying here, and vice versa, when the scale becomes smaller, it indicates that the railway track is high-protruding here. And the operation is simple, easy to detect, more convenient. Moreover, the railway track flatness detection device for construction vehicles can clamp and fix railway tracks of different widths through adjustable L-shaped plates, and can be used for the flatness detection of various railway tracks, which is more convenient.

[0032] Working principle: When the track flatness detection device for building construction is in use, the first positioning wheel 8 is placed on the surface of the railway track. At this time, by starting the two hydraulic devices 11, the two hydraulic devices 11 apply a pulling force on the two hydraulic rods 12 sleeved on the inner surface in the opposite direction through operation, causing them to move towards the opposite surface. At the same time, the two hydraulic rods 12 apply a pulling force on the two L-shaped plates 13 fixedly installed at the opposite ends in the opposite direction, causing them to slide leftward on the two chutes 2 towards the opposite surface. At the same time, the two L-shaped plates 13 drive the two second positioning wheels 14 arranged on the opposite surface of the cross plate to fit into the grooves on both sides of the railway track, completing the positioning. At this time, the positioning of the flatness detection device body 1 is completed. At this time, by pushing the flatness detection device body 1 to slide on the railway track surface and observing the scale 10 set on the fixed column 9, when passing through an uneven area, the first positioning wheel 8 will apply an upward thrust on the fixed block 7 arranged on the upper surface. At the same time, the fixed block 7 drives the fixing plate 6 fixedly sleeved on the outer surface to move upward. The fixing plate 6 applies a pressure on the eight springs 5 fixedly installed on the upper surface, causing them to contract. At the same time, the fixed block 7 applies an upward thrust on the fixed column 9 fixedly installed on the upper surface, causing it to move upward. At this time, the scale set on the fixed column 9 can be read. When the scale becomes smaller, it indicates a high protrusion here. When a low-lying railway track is detected, the spring 5 expands due to its own elastic potential energy. The spring 5 applies a downward thrust on the fixing plate 6 fixedly installed on the lower surface. At the same time, the fixing plate 6 drives the fixed block 7 fixedly sleeved on the inner surface to move downward. The fixed block 7 applies a downward thrust on the first positioning wheel 8 arranged on the lower surface, causing it to move downward and fit the slide rail. At the same time, the fixed block 7 drives the fixed column 9 fixedly installed on the upper surface to move downward. At this time, the scale set on the surface of the fixed column 9 is read. When the reading becomes larger, it indicates a low-lying area here.
