[0001] The utility model relates to the technical field of highway compaction, in particular to a compaction device for highway construction. Background Art

[0002] With the continuous development of social economy and the continuous improvement of people's living standards, the number of vehicles has gradually increased, causing serious damage to the roads. Therefore, highway maintenance departments need to frequently maintain and repair the roads. At present, in the process of paving and maintaining highways, in order to make the road surface stronger after construction, it is necessary to compact the road surface, and compacting devices are often used for this.

[0003] The existing compacting device for highway construction has only one set of compacting blocks, which results in a smaller compacting area during the actual compaction work, thereby further leading to lower work efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problems in the above background and to propose a tamping device for highway construction.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a compacting device for road construction, comprising a base, two support frames fixedly mounted on the bottom surface of the base, a cylinder fixedly mounted on the surface of the base, a first compacting plate fixedly mounted on the output end of the cylinder, a lifting device provided on the surface of the base, the lifting device comprising two sliding bars symmetrically distributed on the surface of the base, a slide plate slidably connected to the surface of each of the two sliding bars, a first T-shaped plate fixedly mounted between the two slide plates, a first through-slot provided on the surface of the base, a connecting rod fixedly mounted on the bottom surface of the first T-shaped plate, an end of the connecting rod away from the first T-shaped plate passing through the first through-slot and fixedly mounted with a second compacting plate. The provision of the first compacting plate and the second compacting plate achieves the effect of compacting the ground.

[0006] Preferably, a circular plate is fixedly mounted on the end surface of the slide bar away from the base, and a spring is fixedly mounted between the circular plate and the slide bar. The arrangement of the spring has the effect of limiting the position of the slide bar on the surface of the slide bar.

[0007] Preferably, an L-shaped bracket is fixedly mounted on the surface of the base, a motor is fixedly mounted on the top surface of the L-shaped bracket, and a cam is fixedly mounted on the output end of the motor. The motor drives the cam to rotate, and the cam drives the first T-shaped plate to move.

[0008] Preferably, both sides of the base are provided with stabilizing devices, comprising two U-shaped plates fixedly mounted on both sides of the base, a threaded rod rotatably connected between the inner walls of the two ends of the U-shaped plates, and a rotating wheel fixedly mounted on one end of the threaded rod. The arrangement of the rotating wheel serves to drive the threaded rod to rotate.

[0009] Preferably, the inner wall surface of the U-shaped plate is provided with a groove, the surface of the threaded rod is threadedly connected to the second T-shaped plate, and the second T-shaped plate is slidably connected to the groove via the threaded rod. The threaded rod has the effect of driving the second T-shaped plate to move inside the groove.

[0010] Preferably, two second through grooves are provided on the surface of the base, and two round rods are fixedly installed on the bottom surface of the second T-shaped plate. The ends of the two round rods away from the second T-shaped plate pass through the second through grooves and are fixedly installed with pulleys. The setting of the second T-shaped plate has the effect of driving the round rods and pulleys to move.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] When the cam is rotated, the first tamping plate and the second tamping plate are moved up and down alternately to compact the road surface, thereby improving the efficiency of the compaction operation.

[0013] 2. In the utility model, a stabilizing device is provided. When the stability of the device during the compaction process needs to be improved, the rotating wheel is rotated first. The rotation of the rotating wheel drives the threaded rod to rotate. The rotation of the threaded rod drives the second T-shaped plate to move upward inside the groove. The second T-shaped plate moves upward inside the groove, drives the round rod to move upward. The upward movement of the round rod drives the pulley to move upward. The pulley moves downward to separate itself from the ground. The pulley and the ground are separated so that the support frame contacts the ground. When the support frame contacts the ground, the rotation of the rotating wheel is stopped. Through the cooperation of the above structure, the pulley can be separated from the ground, thereby improving the stability of the device during work and avoiding the displacement of the device due to vibration and contact between the pulley and the ground during the compaction work.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] The specific configuration and functions of the lifting device 5 and the stabilizing device 6 will be described in detail below.

[0024] In this embodiment: a lifting device 5 is provided on the surface of the base 1, and the lifting device 5 includes two sliding rods 501, and the two sliding rods 501 are symmetrically distributed on the surface of the base 1. The surfaces of the two sliding rods 501 are slidably connected with slides 502, and a first T-shaped plate 503 is fixedly installed between the two slides 502. A first through groove 504 is opened on the surface of the base 1, and a connecting rod 505 is fixedly installed on the bottom surface of the first T-shaped plate 503. The end of the connecting rod 505 away from the first T-shaped plate 503 passes through the first through groove 504 and is fixedly installed with a second tamping plate 506.

[0025] In this embodiment, the provision of the first tamping plate 4 and the second tamping plate 506 has the effect of tamping the ground.

[0026] Specifically, a circular plate 510 is fixedly mounted on the surface of one end of the slide rod 501 away from the base 1 , and a spring 511 is fixedly mounted between the circular plate 510 and the slide plate 502 .

[0027] In this embodiment, the setting of the spring 511 has the effect of limiting the position of the slide plate 502 on the surface of the slide bar 501.

[0028] Specifically, an L-shaped bracket 507 is fixedly mounted on the surface of the base 1, a motor 508 is fixedly mounted on the top surface of the L-shaped bracket 507, and a cam 509 is fixedly mounted on the output end of the motor 508. The motor 508 drives the cam 509 to rotate, and the cam 509 drives the first T-shaped plate 503 to move.

[0029] In this embodiment: a stabilizing device 6 is provided on both side surfaces of the base 1, and the stabilizing device 6 includes two U-shaped plates 61, and the two U-shaped plates 61 are fixedly installed on the two side surfaces of the base 1. A threaded rod 62 is rotatably connected between the inner walls at both ends of the U-shaped plate 61, and a rotating wheel 63 is fixedly installed at one end of the threaded rod 62. When it is necessary to improve the stability of the device during the tamping process, first rotate the wheel 63. The rotation of the wheel 63 drives the threaded rod 62 to rotate. The rotation of the threaded rod 62 drives the second T-shaped plate 65 to move upward inside the groove 64. The second T-shaped plate 65 moves upward inside the groove 64, driving the round rod 67 to move upward. The upward movement of the round rod 67 drives the pulley 68 to move upward. The pulley 68 moves downward to separate itself from the ground. The pulley 68 is separated from the ground so that the support frame 2 contacts the ground. When the support frame 2 contacts the ground, stop rotating the wheel 63. Through the cooperation of the above structure, the pulley 68 can be separated from the ground, thereby improving the stability of the device during operation and avoiding the device from vibrating and contacting the pulley 68 with the ground during the tamping work, thereby causing the device to be displaced.

[0030] Specifically, a groove 64 is formed on the inner wall surface of the U-shaped plate 61 , and a second T-shaped plate 65 is threadedly connected to the surface of the threaded rod 62 . The second T-shaped plate 65 is slidably connected to the threaded rod 62 and the groove 64 .

[0031] In this embodiment, the threaded rod 62 is provided to drive the second T-shaped plate 65 to move inside the groove 64 .

[0032] Specifically, two second through slots 66 are formed on the surface of the base 1 , and two round rods 67 are fixedly mounted on the bottom surface of the second T-shaped plate 65 . The ends of the two round rods 67 away from the second T-shaped plate 65 pass through the second through slots 66 and are fixedly mounted with pulleys 68 .

[0033] In this embodiment, the second T-shaped plate 65 is provided to drive the round rod 67 and the pulley 68 to move.

[0034] Working principle: By setting up the lifting device 5, when the device needs to be used, the base 1 can be moved by first pushing the U-shaped plate 61 and the pulley 68. When the device moves to the road surface that needs to be compacted, the cylinder 3 is first activated, and the cylinder 3 starts to drive the first compacting plate 4 to move. The first compacting plate 4 moves to compact the ground, and then the second motor 508 is started. The second motor 508 starts to drive the cam 509 to rotate. The rotation of the cam 509 will push the first T-shaped plate 503 to move downward. The downward movement of the first T-shaped plate 503 drives the slide plate 502 to move downward on the surface of the slide bar 501. At the same time, the movement of the slide plate 502 on the surface of the slide bar 501 also drives the spring 511 The second tamping plate 506 moves downward to compact the ground. When the cam 509 rotates to separate it from the first T-shaped plate 503, the rebound force of the spring 511 is used to reset the second tamping plate 506. As the cam 509 continues to rotate, the second tamping plate 506 continuously compacts the ground. Through the cooperation of the above-mentioned structure, the first tamping plate 4 and the second tamping plate 506 are moved up and down in an alternating cycle to compact the road surface, thereby improving the efficiency of the compaction operation. When it is necessary to improve the stability of the device during the tamping process, first rotate the wheel 63. The rotation of the wheel 63 drives the threaded rod 62 to rotate. The rotation of the threaded rod 62 drives the second T-shaped plate 65 to move upward inside the groove 64. The second T-shaped plate 65 moves upward inside the groove 64, driving the round rod 67 to move upward. The upward movement of the round rod 67 drives the pulley 68 to move upward. The pulley 68 moves downward to separate itself from the ground. The pulley 68 is separated from the ground so that the support frame 2 contacts the ground. When the support frame 2 contacts the ground, stop rotating the wheel 63. Through the cooperation of the above structure, the pulley 68 can be separated from the ground, thereby improving the stability of the device during operation and avoiding the device from vibrating and contacting the pulley 68 with the ground during the tamping work, thereby causing the device to be displaced.
