Description

Technical Field

[0001] The utility model relates to the field of roadbed construction detection, in particular to a roadbed construction flatness detection device. Background Art

[0002] The roadbed is the foundation of the track or road surface. It is a geotechnical structure formed by excavation or filling. The main function of the roadbed is to provide necessary conditions for track or road paving and train or vehicle operation. Therefore, whether the roadbed is paved up to standard is very important for the construction of subsequent projects. During the roadbed paving process, the overall flatness of the roadbed needs to be ensured. There are three common methods for testing the flatness of the roadbed.

[0003] The existing roadbed construction flatness detection equipment, when conducting detection, fixes the equipment to the roadbed, observes the level ruler and records the horizontal flatness of the equipment, then lowers the plumb bob, and observes and records the inclination angle of the plumb bob through the plumb bob and the scale plate on the base. However, after the detection, when reading the data, due to the height difference between the plumb bob and the scale plate, errors may easily occur when reading the data. Therefore, it is necessary to provide a new roadbed construction flatness detection equipment to solve the above technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a roadbed construction flatness detection device.

[0005] The roadbed construction flatness detection equipment provided by the utility model comprises: a base plate, a detection component, a supporting telescopic frame, a lifting frame and a horizontal calibration component, the supporting telescopic frame is inserted into the base plate, the lifting frame is fixedly connected to the base plate, the horizontal calibration component is fixedly installed on the upper end surface of the lifting frame, the detection component is fixedly installed on the lower end surface of the lifting frame, the detection component comprises a circular scale plate, a laser lamp, a reflector and a vertical line, the circular scale plate is fixedly connected to the lower end surface of the lifting frame, one end of the vertical line is fixedly connected to the center position of the circular scale plate, the laser lamp is fixedly connected to the other end of the vertical line, the reflector is fixedly connected to the upper end surface of the base plate, and the center of the reflector and the laser lamp are on the same vertical line.

[0006] Preferably, the supporting telescopic frame comprises a telescopic scale and a plurality of supporting legs, the telescopic scale is inserted into the bottom plate, and the plurality of supporting legs are rotatably connected to the telescopic scale.

[0007] Preferably, the supporting foot includes a first sleeve, a first threaded rod and a positioning sleeve, the first threaded rod is rotatably connected to the telescopic scale, the first sleeve is threadedly connected to the first threaded rod, and the positioning sleeve is rotatably connected to the first sleeve.

[0008] Preferably, the lifting frame includes a plurality of second sleeves, a plurality of second threaded rods and a fixing plate, the plurality of second sleeves are rotatably connected to the bottom plate, the plurality of second threaded rods are threadedly connected to the plurality of second sleeves, and the fixing plate is rotatably connected to the plurality of second threaded rods.

[0009] Preferably, the horizontal calibration assembly includes a level ruler, which is fixedly connected to the upper end surface of the fixed plate.

[0010] Compared with the related art, the roadbed construction flatness detection equipment provided by the utility model has the following beneficial effects: when the equipment determines the detection area on the roadbed and fixes the equipment, turn on the laser light. If the light emitted by the laser light returns to the laser light along the original path after being reflected by the reflective plate, it means that the flatness of this area is good. If the light emitted by the laser light appears as a bright spot on the circular scale plate, when the bright spot is close to the vertical line and it is inconvenient to read the data, the bright spot can be offset by adjusting the lifting frame, thereby facilitating data reading. When the bright spot is far from the vertical line, the data can be read directly. The data measured in this way is more accurate than the data obtained by visual inspection.

DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0017] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1A schematic diagram of the overall structure of a preferred embodiment of a roadbed construction flatness detection device provided by the utility model; Figure 2 A horizontal cross-sectional view of a preferred embodiment of a roadbed construction flatness detection device provided by the utility model; Figure 3 A schematic structural diagram of a preferred embodiment of a roadbed construction flatness detection device provided by the utility model; Figure 4 The utility model provides a longitudinal cross-sectional view of a preferred embodiment of a roadbed construction flatness detection device.

[0018] In the specific implementation process, Figure 1-4 As shown, the utility model provides a roadbed construction flatness detection equipment, including: a base plate 1, a detection component, a supporting telescopic frame, a lifting frame and a horizontal calibration component, the supporting telescopic frame is inserted into the base plate 1, the lifting frame is fixedly connected to the base plate 1, the horizontal calibration component is fixedly installed on the upper end surface of the lifting frame, the detection component is fixedly installed on the lower end surface of the lifting frame, the detection component includes a circular scale plate 14, a laser lamp 12, a reflector 13 and a vertical line 11, the circular scale plate 14 is fixedly connected to the lower end surface of the lifting frame, one end of the vertical line 11 is fixedly connected to the center position of the circular scale plate 14, the laser lamp 12 is fixedly connected to the other end of the vertical line 11, the reflector 13 is fixedly connected to the upper end surface of the base plate 1 and the center of the reflector 13 and the laser lamp 12 are on the same vertical line.

[0019] The supporting telescopic frame comprises a telescopic scale 5 and a plurality of supporting legs. The telescopic scale 5 is inserted into the bottom plate 1 , and the plurality of supporting legs are rotatably connected to the telescopic scale 5 .

[0020] The supporting foot comprises a first sleeve 3, a first threaded rod 4 and a positioning tube 2, the first threaded rod 4 is rotatably connected to the telescopic scale 5, the first sleeve 3 is threadedly connected to the first threaded rod 4, and the positioning tube 2 is rotatably connected to the first sleeve 3.

[0021] The lifting frame includes a plurality of second sleeves 7, a plurality of second threaded rods 8 and a fixing plate 9. The plurality of second sleeves 7 are rotatably connected to the base plate 1. The plurality of second threaded rods 8 are threadedly connected to the plurality of second sleeves 7. The fixing plate 9 is rotatably connected to the plurality of second threaded rods 8.

[0022] The horizontal calibration assembly includes a level ruler 10 , which is fixedly connected to the upper end surface of the fixing plate 9 .

[0023] The working principle provided by the utility model is as follows: before performing a roadbed flatness test, the equipment needs to be calibrated on a flat road surface. First, determine the area to be tested, and then adjust the telescopic scale 5. After the adjustment is completed, fix the four positioning cylinders 2 to the flat road surface, and then turn on the laser lamp 12 suspended by the vertical line 11. If the light of the laser lamp 12 is reflected by the reflector 13 on the base, a bright spot is displayed on the circular scale plate 14 at the bottom of the fixed plate 9. At this time, it is necessary to rotate the first sleeve 3. The first sleeve 3 is threadedly connected to the first threaded rod 4, so the first sleeve 3 drives the first threaded rod 4 to rotate until the reflected light of the laser lamp 12 returns to the original path. At this time, observe the level ruler 10 on the fixed plate 9. If the bubble in the level ruler 10 is not in the center, it is necessary to rotate the second sleeve 7 in the opposite direction to the bubble. The second sleeve 7 drives the second threaded rod 8 threadedly connected to it to rotate, so that the second threaded rod 8 drives the fixed plate 9 to rise, so as to adjust the fixed plate 9 to a horizontal state, and then the roadbed flatness test can be performed.

[0024] When the inclined roadbed needs to be inspected, first, determine the area to be inspected, and then adjust the telescopic scale 5. After the adjustment is completed, fix the four positioning cylinders 2 to a section of the flat roadbed of the roadbed to be tested, and then turn on the laser lamp 12 suspended at the bottom of the vertical line 11. The light emitted by the laser lamp 12 will pass through the reflector 13 fixed on the base plate 1 and reflect onto the circular scale plate 14 fixed on the bottom of the fixed plate 9. The position of the light spot on the circular scale plate 14 at this time is recorded, and this position is used as the reference point for subsequent inspections. The data obtained from the subsequent inspections are compared and calculated with this reference point. It should be noted that when performing some calculations, the placement direction of the detection equipment may change each time, resulting in the center of the circular scale plate 14, the reference point and the position of the bright spot during inspection not being on the same straight line. Therefore, when performing part of the calculation, the measured straight-line distance between the reference point and the bright spot cannot be directly used as the data used for calculation.

[0025] When testing the flatness of the roadbed, first, according to the area to be tested, the telescopic ruler 5 is pulled out or pushed in, and the telescopic ruler 5 slides in the slide groove 6. After adjustment, the positioning cylinder 2 is fixed to the roadbed, and then the laser lamp 12 suspended at the bottom of the vertical line 11 is turned on. After the light of the laser lamp 12 is reflected by the reflector 13 on the bottom plate 1, if a light spot is formed on the circular scale plate 14 at the bottom of the fixed plate 9, it means that the roadbed is uneven. At this time, the equipment is in a tilted state. If the light spot is close to the vertical line 11 and it is inconvenient to read the scale of the circular scale plate 14, the second sleeve 7 at the lower position is rotated, and the second sleeve 7 drives the second threaded rod 8 threadedly connected to it to rotate until the bubble in the level ruler 10 is adjusted to the center position. At this time, the fixed plate 9 and the circular scale plate 14 are in a horizontal state, and then the data of the light spot on the circular scale plate 14 is read. If the light spot is far from the vertical line 11, it is convenient to read the light spot. When marking on the circular scale plate 14, directly record the data of the circular scale plate 14. At this time, the degree of the angle formed by the incident light and the reflected light is twice the degree of the angle formed by the roadbed in the detection area and the horizontal plane. It should be noted that if the detection is carried out on an inclined roadbed, the equipment must first be fixed to a flat inclined roadbed, and then the laser light 12 is turned on to record the position of the light spot emitted by the laser light 12 on the circular scale plate 14. This is used as a reference point, and then the detection can be carried out in the above manner. The difference is that the reference point at this time replaces the position of the center of the circular scale plate 14 in the above process. The data obtained by the detection must be calculated with the reference point as the initial position. The data measured in the above manner is obtained by reflecting the light of the laser light 12 onto the circular scale plate 14, so the obtained data is more accurate, thereby avoiding the error caused by direct visual inspection.
