[0027] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] like Figure 1-3As shown, a small intelligent compaction device for transition section construction includes a frame 1, a cab 2 mounted on the top of the frame 1, and two rollers 4 connected to the bottom of the frame 1 via a shock absorber frame 3; at least one end of the roller 4 is located on the outside of the frame 1.

[0029] This invention achieves edge compaction of the transition section structure by using a roller located on the outside of the frame, effectively solving the problem that traditional small compaction equipment cannot achieve edge compaction.

[0030] Specifically, the vehicle frame 1 includes a front frame 101 and a rear frame 102, which are hinged together; the driver's cab 2 is mounted on the rear frame 102.

[0031] Specifically, a front roller 401 is rotatably connected to the lower part of the front frame 101 via a front shock absorber 301, and the front shock absorber 301 is located at both ends of the front roller 401; a rear roller 402 is rotatably connected to the lower part of the rear frame 102 via a rear shock absorber 302, the rear shock absorber 302 is located at one end of the rear roller 402, and the other end of the rear roller 402 is located on the outside of the rear frame 102.

[0032] Since the front roller 401 has a steering function in addition to its rolling function, this embodiment does not modify the structure of the front roller 401 considering the cost of structural modification. However, it should be noted that if only the compaction effect is considered, those skilled in the art can modify the structure of the front roller 401 in specific implementations, making one end protrude from the front frame 101.

[0033] Specifically, the rear shock absorber frame 302 includes a roller shaft 321, which is installed inside the rear roller pressure roller 402 via a bearing 322. One end of the roller shaft 321 is vertically connected to a vertical rod 323, and the top end of the vertical rod 323 is connected to a lower shock absorber plate 324. Multiple shock absorber rods 325 are installed on the top of the lower shock absorber plate 324. Shock absorber springs 326 are sleeved on the shock absorber rods 325. An upper shock absorber plate 327 is slidably connected to the top of the shock absorber rods 325. The two ends of the shock absorber springs 326 abut against the opposite surfaces of the lower shock absorber plate 324 and the upper shock absorber plate 327. The upper shock absorber plate 327 is installed on the rear frame 102.

[0034] Specifically, the lower damping plate 324 and the upper damping plate 327 are parallel, and the lower damping plate 324 is a U-shaped plate.

[0035] like Figure 4As shown, in specific implementation, in order to avoid the connection between the vertical rod 323 and the lower damping plate 324 being crushed, the rear roller pressure roller 402 can be divided into two parts in the middle, exposing the roller shaft 321 inside the rear roller pressure roller 402. A vertical rod 323 is then installed on the exposed part of the roller shaft 321 through a bearing, and the top end of the newly installed vertical rod 323 is connected to the other end of the lower damping plate 324, sharing the pressure of the lower damping plate 324 together with the original vertical rod 323.

[0036] The lower damping plate 324 is designed to fix the rear damping frame 302, preventing the rear roller pressure roller 402 from rotating circumferentially around the rear roller pressure roller 402 when it rolls forward to press.

[0037] Specifically, a limiting block 328 is also installed on the top of the shock absorber 325. The limiting block 328 is located above the upper shock absorber 327 and abuts against the upper surface of the upper shock absorber 327.

[0038] Specifically, the driver's cab 2 is equipped with a controller 201 and an electric steering wheel 202. The controller 201 is equipped with a position sensor and a direction sensor. The controller 201 and the electric steering wheel 202 are electrically connected.

[0039] The present invention achieves precise intelligent control of the compaction equipment by controlling the electronically controlled steering wheel 202 through the controller 201.

[0040] Specifically, a first laser ranging sensor 421 is installed on one end of the rear roller 402 located outside the rear frame 102, and a second laser ranging sensor 411 is installed on the same side of the front roller 401. Both the first laser ranging sensor 421 and the second laser ranging sensor 411 are electrically connected to the controller 201.

[0041] Specifically, an obstacle avoidance radar 111 is installed at the front end of the front frame 101, and the obstacle avoidance radar 111 is electrically connected to the controller 201.

[0042] Specifically, it also includes a remote terminal 5, which is wirelessly connected to the controller 201.

[0043] Specifically, a front roller 401 is rotatably connected to the underside of the front frame 101 via a front shock absorber 301. The front shock absorber 301 is located at one end of the front roller 401, and the other end of the front roller 401 is located on the outside of the front frame 101 (not shown in the figure). In a practical implementation, one end of the front shock absorber 301 can be removed, and the length of the removed front roller 401 can be extended so that it is located on the outside of the front frame 101.

[0044] Specifically, such as Figure 5 As shown, the roller 4 provided by the present invention has two eccentric blocks symmetrically arranged inside. The eccentric blocks are driven to rotate simultaneously by a toothed belt and rotate with a 180-degree compensation position. When the roller 4 needs to perform compaction, the rotation of the eccentric blocks causes the roller 4 to generate a vibration effect, thereby improving the compaction effect of the roller 4.

[0045] The usage process of this invention is as follows:

[0046] When the compaction equipment provided by this invention enters the transition section for construction, the second laser ranging sensor 411 will detect the distance between the compaction equipment and the transition section structure before the first laser ranging sensor 421. Since the front roller 401 does not protrude from the frame 1, the compaction equipment can appropriately approach the transition section structure when it enters the transition section. During the entry process, the controller 201 fine-tunes the electronically controlled steering wheel 202 according to the distance signal detected by the second laser ranging sensor 411 to ensure that when the first laser ranging sensor 421 detects the distance signal between the rear roller 302 and the transition section structure, the initial distance detected by the first laser ranging sensor 421 to the transition section structure is within the range of 0-2 cm, thus achieving edge compaction from the beginning of the compaction equipment construction.
