Description

Technical Field

[0001] The utility model relates to the field of road and bridge construction, and particularly relates to a roadbed compaction device for road and bridge construction. Background Technique

[0002] In the field of road and bridge construction, engineers and construction workers are responsible for planning, designing, and building roads, bridges, and related infrastructure. This field involves knowledge and technologies in multiple aspects such as civil engineering, structural engineering, and traffic engineering. In road and bridge construction, roadbed compaction devices are used to reinforce and compact the roadbed to ensure the stability and durability of the road or bridge;

[0003] The existing roadbed compaction devices only compact the roadbed by the gravity factor of the pressing rollers. However, since there is only one compaction method for the compaction device, the roadbed compaction device needs to move back and forth on the roadbed for compaction to ensure the compaction quality of the roadbed, thereby resulting in low compaction work efficiency. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a roadbed compaction device for road and bridge construction, which can effectively solve the technical problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A roadbed compaction device for road and bridge construction includes a vehicle frame. Pressing rollers are rotatably installed at both the front and rear of the vehicle frame. Reciprocating compaction structures are arranged at both the front and rear of the vehicle frame. The reciprocating compaction structure includes a compaction plate and two connecting plates. The two connecting plates are respectively slidably installed on the inner walls of both sides of the vehicle frame and are located inside the vehicle frame. The compaction plate is fixedly connected between the two connecting plates and is located at the bottom inside the vehicle frame. Belt wheels one are rotatably installed on both sides of the front of the vehicle frame. Belt wheels two are rotatably installed at the rear of the two belt wheels one on both sides of the front of the vehicle frame. A connecting rod two is connected to the side of the belt wheel two. Chutes are opened on both sides of the vehicle frame. The far sides of the two connecting plates respectively penetrate through the two chutes and are rotatably connected with connecting rods one. One end of the side of the connecting rod one is rotatably connected with one end of the side of the connecting rod two.

[0007] As a further scheme of the utility model, one end of the side of the belt wheel one penetrates through the side wall of the vehicle frame and is fixedly connected to one end of the pressing roller. A transmission belt is sleeved and connected between the belt wheel one and the belt wheel two on the same side.

[0008] As a further scheme of the utility model, a push handle is fixedly installed at the top of the pressing roller at the rear of the vehicle frame. The push handle is in a "C" shape.

[0009] As a further solution of the utility model, a rotating rod is provided on the side surfaces of the four connecting rods 2, a thread groove 1 is opened inside the connecting rod 2, a thread groove 2 is opened on the outer surface of the rotating rod near one end, and a thread groove 3 is opened on the outer surface of the rotating rod near the other end, a limiting circular block is rotatably installed inside the frame between the two compacting plates, a baffle is fixedly installed on the bottom of the limiting circular block through the bottom of the frame, a support frame is fixedly installed inside the frame between the two compacting plates, and a motor is fixedly installed on the top of the support frame.

[0010] As a further solution of the utility model, the output shaft of the motor passes through the support frame and is fixedly connected to the top of the limiting circular block. The limiting circular block is composed of two circular blocks with different diameters, and the diameter of the circular block at the top is larger than that of the circular block at the bottom.

[0011] As a further solution of the utility model, one end of the rotating rod is threadedly connected to the pulley two through the thread groove two, the thread groove one and the thread groove three are adaptively matched with each other, and the length of the thread groove two is equal to twice the length of the thread groove three.

[0012] The beneficial effects of the utility model are as follows: by setting a reciprocating compacting structure, the device can drive the reciprocating compacting structure to operate during use and advancement, thereby compacting the road surface, so that the device can compact the road surface by driving the two compacting plates to move up and down reciprocatingly while compacting the road surface through the two pressing rollers, thereby increasing the compacting means of the device and greatly improving its compacting work efficiency;

[0013] By setting a rotating rod, the connection relationship between the pulley 2 and the connecting rod 2 can be switched. When the thread groove 1 and the thread groove 3 are threadedly meshed, the connection relationship between the pulley 2 and the connecting rod is a fixed connection. At this time, the rotation of the pulley 2 can drive the reciprocating compaction structure to operate. When the thread groove 1 and the thread groove 3 are separated, the connection relationship between the pulley 2 and the connecting rod is a rotating connection. At this time, the rotation of the pulley 2 cannot drive the reciprocating compaction structure to operate. Therefore, after the device is used, it will not drive the reciprocating compaction structure to operate, and thus cannot affect the normal movement of the device.

[0014] Through the motor and the baffle, the motor is started to drive the baffle to rotate through the limit circle. When the two ends of the baffle rotate to the bottom of the two compacting plates respectively, the motor is turned off and the two compacting plates are blocked by the baffle, so that when the reciprocating compacting structure cannot operate, the two compacting plates will not drop due to their own gravity.

Specific embodiments

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figure 1-4 shown, a road and bridge construction subgrade compaction device includes a vehicle frame 1. Pressure rollers 2 are rotatably installed at the front and rear of the vehicle frame 1. Reciprocating compaction structures 3 are arranged at the front and rear of the vehicle frame 1. The reciprocating compaction structure 3 includes a compaction plate 4 and two connecting plates 5. The two connecting plates 5 are respectively slidably installed on the inner walls of the two sides of the vehicle frame 1 and are located inside the vehicle frame 1. The compaction plate 4 is fixedly connected between the two connecting plates 5 and is located at the bottom inside the vehicle frame 1. First pulleys 8 are rotatably installed on both sides of the front of the vehicle frame 1. Second pulleys 18 are rotatably installed on both sides of the front of the vehicle frame 1 behind the two first pulleys 8. A second connecting rod 9 is connected to the side of the second pulley 18. Chutes 6 are opened on both sides of the vehicle frame 1. One ends of the two connecting plates 5 away from each other respectively penetrate through the two chutes 6 and are rotatably connected to a first connecting rod 7. One end of the side of the first connecting rod 7 is rotatably connected to one end of the side of the second connecting rod 9.

[0022] In this embodiment, one end of the pressure roller 2 is fixedly connected to the side of the first pulley 8 penetrating through the side wall of the vehicle frame 1. A transmission belt is sleeved and connected between the first pulley 8 and the second pulley 18 on the same side. When the vehicle frame 1 moves forward, the two pressure rollers 2 are driven to rotate, driving the four first pulleys 8 to rotate, and then driving the four second pulleys 18 to rotate through the four transmission belts.

[0023] In this embodiment, a push handle 10 is fixedly installed on the rear part of the vehicle frame 1 above the pressure roller 2. The push handle 10 is in a "C" shape, and the vehicle frame 1 can be pushed through the push handle 10.

[0024] In this embodiment, a rotating rod 13 is provided on the side of each of the four connecting rods 2 9, a thread groove 12 is provided inside the connecting rod 2 9, a thread groove 2 14 is provided on the outer surface of the rotating rod 13 near one end, and a thread groove 3 15 is provided on the outer surface of the rotating rod 13 near the other end. A limiting circular block 16 is rotatably installed inside the frame 1 between the two compacting plates 4, a baffle 17 is fixedly installed at the bottom of the frame 1 through the bottom of the limiting circular block 16, a support frame is fixedly installed inside the frame 1 between the two compacting plates 4, and a motor 11 is fixedly installed on the top of the support frame;

[0025] Rotate the rotating rod 13 to separate the thread groove three 15 from the thread groove one 12, but the rotating rod 13 is still threadedly connected to the pulley two 18 through the thread groove two 14. At this time, the relationship between the pulley two 18 and the connecting rod two 9 is only a rotational connection relationship. Therefore, the rotation of the pulley two 18 cannot drive the connecting rod two 9 to rotate, thereby making the reciprocating compaction structure 3 unable to operate, and thereby making it impossible for the two compaction plates 4 at one end of the device to move up and down. At this time, start the motor 11 again to drive the baffle 17 to rotate through the limiting circle 16. When the two ends of the baffle 17 rotate to the bottom of the two compaction plates 4 respectively, turn off the motor 11, and the two compaction plates 4 are blocked by the baffle 17, so that when the reciprocating compaction structure 3 cannot operate, its two compaction plates 4 will not drop due to their own gravity.

[0026] In this embodiment, the output shaft of the motor 11 passes through the support frame and is fixedly connected to the top of the limiting circular block 16. The limiting circular block 16 consists of two circular blocks with different diameters, and the diameter of the circular block at the top is larger than that of the circular block at the bottom.

[0027] In this embodiment, one end of the rotating rod 13 is threadedly connected to the pulley 2 18 through the thread groove 2 14 , the thread groove 1 12 and the thread groove 3 15 are adaptively matched to each other, and the length of the thread groove 2 14 is equal to twice the length of the thread groove 3 15 .

[0028] It should be noted that the utility model is a roadbed compacting device for road and bridge construction. When in use, the frame 1 is pushed forward by the push handle 10 to drive the two pressure rollers 2 to rotate, thereby compacting the road and bridge pavement. While the two pressure rollers 2 rotate, the four pulleys 18 are driven to rotate, and then the four transmission belts drive the four pulleys 2 18 to rotate, thereby driving the four connecting rods 2 9 to rotate, and then driving the four connecting rods 1 7 to rotate. However, since the connecting rod 1 7 is limited by the slide groove 6, the four connecting rods 1 7 will slide inside the four slide grooves 6. The continuous rotation of the pulley 2 18 can drive the connecting rod 1 7 to move up and down inside the slide groove 6, and then drive the two compacting plates 4 to move up and down through the four connecting plates 5, thereby compacting the pavement. When the device compacts the pavement through the two pressure rollers 2, it can also compact the pavement by driving the two compacting plates 4 to move up and down.

[0029] When the device is used up, rotate the rotating rod 13 to separate the thread groove three 15 from the thread groove one 12. Since the length of the thread groove two 14 is equal to twice the length of the thread groove three 15, the rotating rod 13 is still threadedly connected to the pulley two 18 through the thread groove two 14. At this time, the relationship between the pulley two 18 and the connecting rod two 9 is only a rotational connection relationship. Therefore, the rotation of the pulley two 18 cannot drive the connecting rod two 9 to rotate, thereby making the reciprocating compaction structure 3 unable to operate, and thereby making it impossible for the two compaction plates 4 at one end of the device to move up and down. At this time, start the motor 11 again to drive the baffle 17 to rotate through the limiting circle 16. When the two ends of the baffle 17 rotate to the bottom of the two compaction plates 4 respectively, turn off the motor 11, and the two compaction plates 4 are blocked by the baffle 17, so that when the reciprocating compaction structure 3 cannot operate, its two compaction plates 4 will not fall due to their own gravity.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
