Description

Technical Field

[0001] This utility model relates to the field of roadbed construction technology, and specifically to a roadbed construction flatness detection device. Background Technology

[0002] The smoothness of the roadbed directly affects the stress state of the pavement structure layer. If the roadbed is uneven, the stress on different parts of the pavement structure layer will be uneven under vehicle load. When asphalt concrete pavement is laid on an uneven roadbed, the raised parts of the pavement layer will bear greater pressure during vehicle travel, while the depressed parts may experience stress concentration. This will accelerate the damage to the pavement layer, such as cracks and potholes. Existing roadbed smoothness detection devices require specific vehicle models to install, and the detection distance and position are fixed, resulting in a limited range of applications. Utility Model Content

[0003] The purpose of this invention is to provide a roadbed construction flatness detection device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a roadbed construction flatness detection device, comprising a main beam plate, a vehicle connection structure fixedly mounted on one side of the main beam plate, a bracket fixedly mounted on the side end of the main beam plate, a motor fixedly mounted on the inner wall of the bracket, a rotating shaft fixedly mounted on the motor shaft end of the motor, a support fixedly mounted on the other side of the main beam plate, the rotating shaft being rotatably connected to the inner wall of the support, a flatness detection structure mounted on the outer wall of the rotating shaft, and a slot fixedly mounted on the side wall of the main beam plate near the support, the slot being slidably engaged with the flatness detection structure.

[0005] Preferably, the vehicle connection structure includes a crossbar connected to the side wall of the main beam plate.

A screw is installed through the tail surface of the vacuum suction cup. The screw is screwed into one of the screw holes. A horizontal bubble is fixedly installed in the middle of the surface of the crossbar.

[0006] Preferably, the flatness detection structure includes a double-ended stud, which is fixedly mounted on the outer wall of the rotating shaft. Nuts are symmetrically screwed onto the two outer walls of the double-ended stud. The outer wall of the nut is set in a cubic shape and fits against the inner wall of the slot. A flatness detector is fixedly mounted on the outer end of the nut.

[0007] Preferably, limit blocks are fixedly connected to both sides of the crossbar.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: the main beam plate ensures the overall stability of the equipment installation; the vehicle connection structure allows for adjustment of the position of the vacuum suction cup for installation according to different vehicles, thus adapting to different vehicle specifications and ensuring the installation effect and levelness; the bracket ensures the working stability of the motor; and the cooperation between the support and the rotating shaft facilitates stable adjustment of the flatness detection structure.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-3 This utility model provides a roadbed construction flatness detection device, including a main beam plate 1, a vehicle connection structure 2 fixedly mounted on one side of the main beam plate 1, a bracket 3 fixedly mounted on the side end of the main beam plate 1, a motor 4 fixedly mounted on the inner wall of the bracket 3, a rotating shaft 5 fixedly mounted on the motor shaft end of the motor 4, a support 7 fixedly mounted on the other side of the main beam plate 1, the rotating shaft 5 being rotatably connected to the inner wall of the support 7, a flatness detection structure 6 being mounted on the outer wall of the rotating shaft 5, and a slot 8 fixedly mounted on the side wall of the main beam plate 1 near the support 7, the slot 8 being slidably engaged with the flatness detection structure 6.

[0015] The main beam plate 1 ensures the overall stability of the equipment installation. The vehicle connection structure 2 allows for adjustment of the position of the vacuum suction cup 22 according to different vehicles, thus adapting to different vehicle specifications and ensuring the installation effect and levelness. The bracket 3 ensures the working stability of the motor. The support 7 and the rotating shaft 5 work together to facilitate stable adjustment of the flatness detection structure 6. The slot 8 restricts the displacement trajectory of the flatness detection structure 6 and prevents it from rotating with the rotating shaft 5. The position of the flatness detection structure 6 can be quickly adjusted according to the width of the roadbed to be inspected and the specific location of the roadbed to be inspected. It is easy to adjust and highly practical.

[0016] The vehicle connection structure 2 includes a crossbar 21, which is connected to the side wall of the main beam plate 1. The inner wall of the crossbar 21 is evenly provided with multiple screw holes 25. The outer wall of the crossbar 21 is fitted with a vacuum suction cup 22. The tail surface of the vacuum suction cup 22 is fitted with a screw 23, which is screwed into one of the screw holes 25. A horizontal bubble 24 is fixedly fitted in the middle of the surface of the crossbar 21.

[0017] When the device needs to be connected to the vehicle, select a smooth position on the front and rear bumpers according to the vehicle's specifications. Adjust the position of the vacuum suction cups 22 on the crossbar 21 according to the width of the smooth position on the bumper, and connect them to the nearby screw holes 25 with screws 23. The positions of the vacuum suction cups on both sides are symmetrical. At this time, observe the horizontal bubble 24 and adjust the level of the device. After reaching the appropriate position, simultaneously evacuate the vacuum suction cups 22 on both sides to adsorb them onto the vehicle's bumper to complete the installation.

[0018] The flatness detection structure 6 includes a double-ended stud 61, which is fixedly mounted on the outer wall of the rotating shaft 5. Nuts 62 are symmetrically screwed onto the outer walls of the two sides of the double-ended stud 61. The outer wall of the nut 62 is set in a cubic shape. The outer wall of the nut 62 fits against the inner wall of the slot 8. A flatness detector 63 is fixedly mounted on the outer end of the nut 62.

[0019] When the position of the flatness detector 63 needs to be adjusted, the motor 4 is turned on. The motor 4 is a servo motor, which drives the rotating shaft 5 to rotate. At the same time, the double-headed stud 61 driven by the rotating shaft 5 rotates. Since the double-headed stud 61 is screwed to the nut 62, and the nut 62 is restricted by the slot 8, it will not rotate with the double-headed stud 61. At this time, the nuts 62 on both sides will move towards each other. According to the rotation direction of the motor 4, the two nuts 62 will move towards each other or away from each other, thereby driving the flatness detector 63 to move. It is convenient to use and highly practical.

[0020] Limiting blocks are fixedly connected to both sides of the crossbar 21.

[0021] The limit block ensures the stability of the crossbar 21 during installation.

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