[0027] As attached Figure 1 To Attachment Figure 5 As shown, the utility model provides a telescopic road construction measuring device, including a device main body 1, the device main body 1 includes a vertical plate 11, a clamping plate 12 and a track plate 13, the vertical plate 11 is provided with two groups of clamping plates 12 fixedly welded between the front and rear, and the opposite surfaces of the vertical plate 11 are fastened with an adjustment structure 2 by bolts; the track plate 13 is fixedly connected between the two groups of vertical plates 11, and a reference rod 4 is clamped inside the track plate 13; a width measuring component 3 is clamped on the clamping plate 12; a sleeve 51 is sleeved on the outside of the reference rod 4; a connecting rod 52 is fixedly connected between two groups corresponding to the left and right positions of the sleeve 51, a top block 53 is clamped on the connecting rod 52, and the top block 53, the connecting rod 52 and the sleeve 51 are assembled into an elevation measuring component 5.

[0028] When the utility model is in use, at the location where the expansion joint of the telescopic road is to be constructed, the main body 1 of the device is placed on the road surfaces on both sides of the expansion joint, and after the turning handle 2201 is turned, the transmission belt 23 is driven to rotate through the turning rod 22, and the transmission belt 23 and the two-way threaded rod 24 are rotated, and the threaded sleeve 3102 is also driven to move until the block 31 is attached to the position where the expansion joint is to be installed, and then the measuring ruler 32 is pulled to make the block 3201 attached to a block 31, and the value read by the measuring ruler 32 is the measured value of the width of the expansion joint; after the reference rod 4 is adjusted, the connecting rod 52 is pressed downward, and the two sleeves 51 and the top block 53 are driven to move downward synchronously until the top block 53 is attached to the top of the expansion joint, and a height difference appears between the top edge of the sleeve 51 and the reference plate 402, which is the height difference between the top of the expansion joint and the road surface, thereby measuring the elevation of the expansion joint, and completing the expansion joint construction measurement of the telescopic road.

[0029] As attached Figure 3 As shown, the device main body 1 also includes a moving plate 14, the bottom surface of the moving plate 14 is provided with a spring, the bottom end of the spring is connected to the bottom surface of the slide slot 1101, the inside of the moving plate 14 is provided with a through hole, the inside of the through hole is penetrated by the reference rod 4; the inside of the track plate 13 is provided with a track slot 1301, the inside of the track slot 1301 is clamped with the reference rod 4, and one side of the track slot 1301 is provided with a rack; the opposite surface of the vertical plate 11 is provided with a slide slot 1101, the inside of the slide slot 1101 is slidably clamped with the moving plate 14. The track slot 1301 can be used to adjust the position of the reference rod 4 at will, so as to ensure that the measurement result of the top elevation before the expansion joint is installed is more accurate, and the moving plate 14 can allow the sleeve 51 to adjust the height up and down at will to assist in measuring the expansion joint elevation height.

[0030] As attached Figure 6 As shown, the top surface of the reference rod 4 is fixedly connected with a gear 401, the top of the reference rod 4 is installed with a roller, the roller is attached to the top surface of the track groove 1301, a reference plate 402 is welded on the reference rod 4, and the lower part of the reference plate 402 is sleeved with a sleeve 51; the gear 401 is meshed and connected to the rack inside the track groove 1301. When the reference rod 4 is moved, the gear 401 meshes with the rack, and the connecting rod 52 can drive another reference rod 4 to move synchronously, and the reference plate 402 provides the elevation of the road surface where the reference rod 4 is located, so that the top elevation of the expansion joint can be measured through the elevation measuring component 5.

[0031] As attached Figure 6As shown, the top surface of the sleeve 51 is fixedly connected with a circular plate through a rod, and the circular plate is clamped on the top surface of the movable plate 14. When the top surface of the sleeve 51 is attached to the bottom surface of the reference plate 402, the bottom surface height of the top block 53 is consistent with the bottom surface height of the reference rod 4. When the top block 53 is placed on the top of the telescopic rod, the connecting rod 52 is pressed downward to drive the two sleeves 51 and the top block 53 to move downward synchronously until the top block 53 is attached to the top of the expansion joint. There is a height difference between the top edge of the sleeve 51 and the reference plate 402, which is the height difference between the top of the expansion joint and the road surface. This can be used to measure whether the elevation of the expansion joint meets the construction requirements, ensuring that the telescopic road will not cause bumps when driving at the location of the expansion joint after the construction is completed.

[0032] As attached Figure 4 and attached Figure 5 As shown, the adjustment structure 2 includes a connecting frame 21, a rotating rod 22, a transmission belt 23 and a bidirectional threaded rod 24. A round tube is welded to the end surface of the connecting frame 21, and the rotating rod 22 is clamped inside the round tube; a rotating handle 2201 is welded to the end of the rotating rod 22, and two transmission belts 23 are sleeved on the rotating rod 22; the other end of the transmission belt 23 is connected to the bidirectional threaded rod 24, and the outer wall of the bidirectional threaded rod 24 and the outer side of the transmission belt 23 are provided with threads in opposite directions. When the rotating handle 2201 is rotated, the transmission belt 23 is driven to rotate through the rotating rod 22. There is no thread on the threaded rod at the position where the transmission belt 23 is connected to the bidirectional threaded rod 24, and it is only connected by friction. In this way, the transmission belt 23 can drive the bidirectional threaded rod 24 to rotate, so as to realize the movement of the width measuring component 3.

Two blocks 31 are provided. Threaded sleeves 3102 are respectively connected inside the two blocks 31. The measuring ruler 32 is connected inside the bayonet 3101. A stopper 3201 is welded on the measuring ruler 32. The threaded sleeve 3102 is connected to the bidirectional threaded rod 24 through threaded engagement. When the bidirectional threaded rod 24 rotates, the threaded sleeve 3102 is driven to rotate. However, the block 31 cannot rotate due to the restriction of the insertion of the measuring ruler 32. The rotation can be converted into movement so that the threaded sleeve 3102 drives the block 31 to move away from or towards each other until the block 31 is attached to the position where the expansion joint is to be installed, and the width of the expansion joint construction is measured.
