[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Reference Figure 1-2 A road subsidence repair device relates to a plate compactor used for compacting road backfill soil and gravel in the prior art, comprising a plate compactor shell 1 and a plate compactor bottom plate 2, wherein the plate compactor shell 1 is fixedly arranged above the plate compactor bottom plate 2, and two supporting folding wheels 3 are symmetrically fixedly installed on both sides of the plate compactor shell 1, such as Figure 1 The supporting folding wheel 3 is in the unfolded state, Figure 1The lower end of the roller 303 in the middle supporting folding wheel 3 is lower than the bottom plate 2 for the plate tamping, so as to facilitate the movement of the plate tamping. Figure 2 The supporting folding wheel 3 is in a folded state, and the lower end of the roller 303 in the supporting folding wheel 3 is higher than the bottom plate 2 for the flat plate tamping, which will not affect the normal use of the flat plate tamping.

[0028] In this embodiment, the supporting folding wheel 3 includes two legs 301, a folding rod 1 302, two rollers 303 and a folding rod 2 304. The two rollers 303 are rotatably installed on the ends of the two legs 301 respectively. The head ends of the two legs 301 are symmetrically rotatably installed on both sides of the housing 1 for the plate tamping, that is, the four legs 301 are symmetrically installed on the four corners of the housing 1 for the plate tamping. The top ends of the folding rod 1 302 and the folding rod 2 304 are rotatably connected in an inverted V shape through a rotating shaft. The folding rod 1 302 and the folding rod 2 304 have the same length, and the ends of the folding rod 1 302 and the folding rod 2 304 are rotatably installed on one side of the two legs 301 respectively.

[0029] In this embodiment, the upper ends of the two supporting folding wheels 3 are synchronously connected through a guide mechanism 4, and the guide mechanism 4 also includes two inner hole guide seats 401, a lifting rod 402 and a connecting seat 403. The two ends of the lifting rod 402 are fixedly connected to the rotating shafts at the top ends of the two folding rods 304, that is, the lifting rod 402 synchronously connects the two folding rods 1 302 and the two folding rods 2 304 in the two supporting folding wheels 3, and the two ends of the lifting rod 402 are respectively lifted and installed in the guide grooves in the two inner hole guide seats 401, and the two inner hole guide seats 401 are respectively fixedly installed on the top ends of the flat plate tamping shell 1, and the connecting seat 403 is fixedly connected to the middle end of the lifting rod 402.

[0030] It should be noted that the lifting rod 402 is driven by the lifting power source to drive the upper ends of the two supporting folding wheels 3 to move along the guide grooves in the inner hole guide seat 401. The above-mentioned power source can be an electric push cylinder or a hydraulic cylinder. The base of the electric push cylinder or the hydraulic cylinder is fixedly installed on the housing 1 for the flat plate compactor, and then the piston rod and the connecting seat 403 in the electric push cylinder or the hydraulic cylinder are fixedly connected. The electric push cylinder or the hydraulic cylinder and the inner hole guide seat 401 are parallel to each other and are vertically installed, that is, the electric push cylinder or the hydraulic cylinder is used to perform lifting and telescopic movements to drive the lifting rod 402, the two folding rods 1 302 and the two folding rods 2 304 to move along the guide grooves in the two inner hole guide seats 401, and the two folding rods 1 302 and the two folding rods 2 304 are synchronously driven to rotate toward the four legs 301, thereby driving the four rollers 303 to rise and fall synchronously.

[0031] It is further explained that, although the electric push cylinder or hydraulic cylinder can realize the automatic synchronous lifting and lowering of the four rollers 303, the cost is relatively high. In addition, since the construction workers using the flat rammer generally have greater strength, the operating mechanism 5 manufactured by the lever principle can be directly used for manual lifting and lowering, that is, the operating mechanism 5 is also installed on the shell 1 of the flat rammer.

[0032] In this embodiment, the operating mechanism 5 includes a support rod 501, an operating rod 502 and a stop assembly, the lifting rod 402 is horizontally arranged, the operating rod 502 and the lifting rod 402 are perpendicular to each other, the support rod 501 is fixedly installed on one side of the housing 1 for the plate compactor, the head end of the operating rod 502 and the top end of the support rod 501 are rotatably connected, and a hinge block 503 is fixedly installed on the lower side of the head end of the operating rod 502, and the hinge block 503 and the connecting seat 403 are rotatably connected. By pulling the end of the operating rod 502 up and down, the lifting rod 402 can be driven to move up and down along the guide grooves in the two inner hole guide seats 401 with more effort.

[0033] In this embodiment, the stop assembly includes an arc-shaped stop block 504 and a stop rod 507. The arc-shaped stop block 504 is fixedly connected to the housing 1 of the flat tamping machine. A guide hole 505 is provided in the arc-shaped stop block 504. The operating rod 502 and the stop rod 507 slide up and down through the guide hole 505. The head end of the stop rod 507 is hinged to the periphery of the operating rod 502. The upper and lower ends of the guide hole 505 are respectively connected to a high limit groove 510 and a low limit groove 506. The high limit groove 510 and the low limit groove 506 are used to limit the up and down movement of the stop rod 507, thereby achieving the purpose of limiting the lifting and lowering of the operating rod 502.

[0034] The spring 508 is compressed and installed between the stop rod 507 and the operating rod 502. The spring 508 in the present application is always in a compressed state, and uses its own elastic force to push the end of the stop rod 507 away from the operating rod 502 and against the inner wall of the guide hole 505. Therefore, when the stop rod 507 and the high limit groove 510 or the low limit groove 506 are pushed to correspond to each other, the spring 508 will push the stop rod 507 to stably fit into the high limit groove 510 or the low limit groove 506, thereby achieving the purpose of limiting the lifting and lowering of the operating rod 502. A side plate 509 is provided in the inner circle of the spring 508. The head end of the side plate 509 is fixedly connected to the operating rod 502, and the end of the side plate 509 slides through the stop rod 507. The side plate 509 is used to install the spring 508 and guide the rotation of the stop rod 507.

[0035] When the plate compactor of the utility model moves on the road surface and does not need to be operated, the construction personnel press the stop rod 507 to approach the operating rod 502 to release the lifting and lowering restriction of the stop rod 507 and the operating rod 502 by the high limit groove 510, and then press the end of the operating rod 502 downward, through the hinge block 503 and the connecting seat 403 transmission, it can more labor-saving drive the lifting rod 402 to move up and down along the guide grooves in the two inner hole guide seats 401, and the lifting rod 402 drives the top ends of the two folding rods 1 302 and the two folding rods 2 304 to move downward, and then the lower ends of the two folding rods 1 302 and the two folding rods 2 304 drive the four legs 301 and the four rollers 303 to rotate downward 90 degrees synchronously, so that the four rollers 303 stand on the road surface, such as Figure 1 The lower end of the roller 303 is lower than the bottom plate 2 for the plate compactor, which is convenient for the movement of the plate compactor. At the same time, the stop rod 507 and the low limit groove 506 correspond to each other, and the spring 508 pushes the stop rod 507 to stably fit into the low limit groove 506, thereby achieving the purpose of limiting the lifting and lowering of the operating rod 502;

[0036] Similarly, when the plate compactor is working, the construction worker presses the stop rod 507 close to the operating rod 502 to release the lifting and lowering restriction of the stop rod 507 and the operating rod 502 by the low limit groove 506, and then pulls the end of the operating rod 502 upward, and then a series of transmissions of the hinge block 503, the connecting seat 403, the lifting rod 402, the two folding rods 302, and the two folding rods 304 are used to drive the four legs 301 and the four rollers 303 to rotate upward 90 degrees synchronously. Figure 2 The lower ends of the four legs 301 and the four rollers 303 are higher than the bottom plate 2 for the flat plate rammer, which will not affect the normal use of the flat plate rammer. At the same time, the stop rod 507 and the high-position limit groove 510 correspond to each other, and the spring 508 will push the stop rod 507 to stably fit into the high-position limit groove 510, thereby achieving the purpose of limiting the lifting and lowering of the operating lever 502.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
