Description

Technical Field

[0001] The utility model relates to the field of road construction, in particular to a construction height control device for a road pavement structure layer. Background Art

[0002] The speed of road construction is constantly increasing, driving the mechanization of highway construction while also placing increasingly stringent requirements on the technical level of construction machinery, construction techniques, pavement materials, and pavement structure design. The technical level of construction machinery and construction techniques have a significant impact on highway grade and construction speed. During the paving process of the road pavement structure layer, the thickness of the structure layer is typically controlled by controlling the height of the roadside hanging line. The paver's sensors detect the hanging line height, and the paving thickness is adjusted accordingly.

[0003] The current support device for detecting hanging wires used in pavers requires workers to frequently twist a handwheel to adjust the height when controlling the height of the hanging wires, which causes the operator to spend more time and energy. Especially when the adjustment range is large, the operation is more inconvenient. Not only that, when used and carried, the device occupies a large space, which increases transportation space and transportation costs.

[0004] Therefore, it is necessary to provide a new road pavement structure layer construction height control device to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a road pavement structure layer construction height control device which is convenient to carry and use and can control the height.

[0006] The utility model provides a device for controlling the construction height of a road pavement structure layer, comprising a base plate and:

[0007] A support shell is provided on the top of the base plate, one side of the support shell is fixedly connected to a positioning shell, an inner cavity of the support shell is movably connected to a clamping column, and the inner cavity of the positioning shell is provided with an adjustment component for adjusting the clamping column, the adjustment component including a second spring and a clamping slot;

[0008] A groove is opened at the top of the clamping column, a screw is provided at the bottom of the inner cavity of the groove, a threaded sleeve is provided on the surface of the screw, an extension plate is fixedly connected to one side of the threaded sleeve, and a torsion block is fixedly connected to the top of the screw.

[0009] As a road pavement structure layer construction height control device provided by the utility model, preferably, one side of the extension plate is movably connected to a support plate through an axle pin, and both sides of the bottom of the threaded sleeve are fixedly connected to sliding rods for limiting use.

[0010] As a road pavement structure layer construction height control device provided by the utility model, preferably, both sides of the base plate are movably connected to the limit plate through an axle pin, the top of the limit plate is fixedly connected to a first spring, the top of the first spring is fixedly connected to a fixing ring, and the bottom of the fixing ring is fixedly connected to a positioning cone.

[0011] As a road pavement structure layer construction height control device provided by the utility model, preferably, a first clamping block is fixedly connected to one side of the top of the extension plate, and a second clamping block used in conjunction with the first clamping block is fixedly connected to one side of the top of the extension plate.

[0012] As a road pavement structure layer construction height control device provided by the present invention, preferably, a ruler is provided on the rear side of the support shell, and a connecting groove is opened on the rear side of the support shell.

[0013] As a road pavement structure layer construction height control device provided by the present invention, preferably, a reinforcement block is fixedly connected to the bottom of the positioning shell, and the reinforcement block is fixedly connected to the support shell on a side close to the support shell.

[0014] As a road pavement structure layer construction height control device provided by the utility model, preferably, the second spring is fixed to one side of the positioning shell, the card slot is opened on one side of the card column, one side of the second spring is fixedly connected to a tooth plate, both sides of the front side of the tooth plate are fixedly connected to a pull rod, and the side of the pull rod away from the tooth plate passes through to the outside of the positioning shell and is fixedly connected to the pull plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The device for controlling the construction height of a road pavement structure layer can first directly drag the clamping column to move upward. When the clamping column moves, the clamping groove in the clamping column will contact the inclined surface of the tooth plate, so the second spring will be forced to retract until it is adjusted to the required height. The height adjustment can be completed by relying on the second spring to drive the tooth plate to reset it. If it is necessary to fine-tune the height, the twisting block can be twisted to rotate the screw rod. At this time, the threaded sleeve will drive the height of the extension plate and the support plate to be fine-adjusted. If it is necessary to fold and store it, the first clamping block can be moved to make the second clamping block disengage from the first clamping block. Since the materials of the first clamping block and the second clamping block are both elastic materials, the support plate can be folded and stored, thereby reducing the occupied space and solving the problem that the existing device for controlling the construction height of a road pavement structure layer is not convenient for folding and storage.

[0022] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0023] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 ,in Figure 1 A schematic structural diagram of a preferred embodiment of the road pavement structure layer construction height control device provided by the utility model; Figure 2 for Figure 1 A schematic structural diagram of the support shell as seen from the rear; Figure 3 for Figure 1 A schematic structural diagram of the regulating assembly shown; Figure 4 for Figure 1 The structural schematic diagram of the cross-section of the support shell shown. A device for controlling the construction height of a road pavement structure layer includes a base plate 1, and further includes: a support shell 2 on the top of the base plate 1, a positioning shell 3 fixedly connected to one side of the support shell 2, a reinforcement block 16 fixedly connected to the bottom of the positioning shell 3, and the reinforcement block 16 is fixed to one side of the support shell 2 to improve the connection strength between the positioning shell 3 and the support shell 2, and the reinforcement block 16 is fixedly connected to the support shell 2 on the side close to the support shell 2, a ruler 14 is provided on the rear side of the support shell 2, a connecting groove 15 is provided on the rear side of the support shell 2, and the connecting groove 15 is provided on the rear side of the support shell 2 to facilitate the storage of the support plate 64, a clamping column 4 is movably connected to the inner cavity of the support shell 2, and an adjustment component 5 for adjusting the clamping column 4 is provided in the inner cavity of the positioning shell 3, and the adjustment component 5 includes a second spring 501 and a clamping groove 502;

[0024] A groove 6 is provided at the top of the card column 4, and a screw 61 is provided at the bottom of the inner cavity of the groove 6. A threaded sleeve 62 is provided on the surface of the screw 61. One side of the threaded sleeve 62 is fixedly connected to an extension plate 63. One side of the extension plate 63 is movably connected to a support plate 64 through an axle pin. By twisting the torsion block 65 to rotate the screw 61, the threaded sleeve 62 will drive the height of the extension plate 63 and the support plate 64 to be fine-tuned. One side of the top of the extension plate 63 is fixedly connected to the first card block 12, and one side of the top of the extension plate 63 is fixedly connected to a first card block 12. The second card block 13 used in the block 12 is made of elastic material. When the user needs to fold and store the support plate 64, the first card block 12 can be moved to disengage the second card block 13 from the first card block 12, and the support plate 64 can be folded and stored. Both sides of the bottom of the threaded sleeve 62 are fixedly connected with a sliding rod 7 for limiting use, which passes through the surface of the sliding rod 7 into the support shell 2. When the threaded sleeve 62 moves, the sliding rod 7 will limit its lifting and lowering movement. The top of the screw 61 is fixedly connected with a torsion block 65.

[0025] Both sides of the base plate 1 are movably connected to the limit plate 8 through an axle pin. The top of the limit plate 8 is fixedly connected to the first spring 9, and the top of the first spring 9 is fixedly connected to the fixing ring 10. When the user needs to position the base plate 1, the limit plate 8 can be folded through the bearing, and then the positioning cone 11 is aimed at the ground and the fixing ring 10 is hit to make the positioning cone 11 descend to fix the base plate 1. The bottom of the fixing ring 10 is fixedly connected to the positioning cone 11.

[0026] The second spring 501 is fixed to one side of the positioning shell 3, and the slot 502 is opened on one side of the card column 4. One side of the second spring 501 is fixedly connected to the tooth plate 503, and both sides of the front side of the tooth plate 503 are fixedly connected to the pull rod 504. First, the card column 4 can be directly dragged to move upward. When the card column 4 moves, the slot 502 in the card column 4 will contact the inclined surface of the tooth plate 503, so the second spring 501 will be forced to retract. Until it is adjusted to the required height, the second spring 501 drives the tooth plate 503 to reset it to complete the height adjustment. The pull rod 504 extends to the outside of the positioning shell 3 away from the tooth plate 503 and is fixedly connected to the pull plate 505.

[0027] The working principle of the road pavement structure construction height control device provided by the present invention is as follows: when the user needs to lower the height of the card column 4, first pull the pull plate 505 to drive the pull rod 504 to move. When the pull rod 504 moves, it will drive the tooth plate 503 to move and squeeze the second spring 501 at the same time. At this time, the tooth plate 503 will be out of the card slot 502, and then the height of the card column 4 can be lowered. Then, if it is necessary to position the base plate 1, the limit plate 8 can be folded through the bearing, and then the positioning cone 11 is aimed at the ground and the fixing ring 10 is hit to make the positioning cone 11 descend to fix the base plate 1. Then, the card column 4 can be directly pulled upward to move. When the lever 4 is in motion, the slot 502 in the lever 4 comes into contact with the inclined surface of the tooth plate 503, so the second spring 501 is forced to retract until it is adjusted to the required height. The second spring 501 drives the tooth plate 503 to reset it to complete the height adjustment. If you need to fine-tune the height, you can twist the torsion block 65 to rotate the screw 61. At this time, the threaded sleeve 62 will drive the extension plate 63 and the support plate 64 to fine-tune the height. If you need to fold and store it, you can move the first block 12 to disengage the second block 13 from the first block 12. Since the materials of the first block 12 and the second block 13 are both elastic materials, the support plate 64 can be folded and stored to reduce occupied space.
