Description

Technical Field

[0001] This utility model relates to a compaction device, specifically a brick compactor for civil engineering. Background Technology

[0002] Square bricks are a common paving material for sidewalks. During construction, it is necessary to ensure the compaction of the square bricks to guarantee the flatness, stability and service life of the paving surface. Currently, when laying sidewalk square bricks, workers mostly use rubber hammers to compact them. However, with the development and application of road paving machines, the manual compaction method is no longer sufficient to meet the needs of the project due to its low efficiency.

[0003] A search revealed that patent CN219528310U discloses a brick compaction device for building construction. It uses a cylinder as the driving force to drive the compaction block and rubber pad downwards, so that the rubber pad comes into contact with the brick and compacts the brick. Because the rubber pad is made of soft material, it can reduce the risk of the brick being crushed.

[0004] While the above solution can use a cylinder to drive the compaction block and rubber pad to compact the floor tiles, it has several drawbacks in actual use. For example, if the cylinder's operating speed is slow and the interval between reciprocations is long, the work efficiency will be low. However, if the cylinder's operating speed is fast and the interval between reciprocations is short, the cylinder will be subjected to greater impact, which will accelerate wear and generate high temperatures, affecting the service life of the equipment. Secondly, using a cylinder for driving requires the installation of an air compressor and power supply system on the equipment. Otherwise, the external air supply pipeline will not only affect the cylinder's response speed but also interfere with the equipment's operating space, resulting in poor performance and requiring improvement.

Detailed Implementation

[0019] 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.

[0020] Please see Figures 1-3In this embodiment of the utility model, a brick compactor for civil engineering includes a base plate 1. Multiple wheels 2 are mounted on the bottom of the base plate 1. A push handle 3 is fixedly mounted at the rear end of the top of the base plate 1. A switch 4 is mounted on the push handle 3. A fuel generator 5 and a support 6 are fixedly mounted on the top of the base plate 1. Multiple vertical rods 8 are slidably mounted on the support 6. A cover 11 is fixedly mounted on the top of the support 6. Two crankshafts 10 are rotatably mounted inside the cover 11 via bearing seats. A connecting rod 9 is hinged to the top of each vertical rod 8, and the top of the connecting rod 9 is rotatably connected to the corresponding crankshaft 10. A first reduction motor 12 is fixedly mounted on the outer wall of the cover 11. Both crankshafts 10 are connected to the transmission shaft of the first reduction motor 12. A pressure block 17 is connected to the bottom end of each vertical rod 8 via an elastic telescopic mechanism. A brushing mechanism is mounted on the front end of the base plate 1.

[0021] By adopting the above-mentioned scheme, this utility model, when in use, after starting the fuel generator 5 to power the device, starts the first reduction motor 12 to drive the two crankshafts 10 to rotate. Then, the connecting rod 9 drives the vertical rod 8 to move up and down on the support 6, thereby driving the pressure block 17 to move up and down through the elastic telescopic mechanism. By pushing the device to move slowly on the laid square bricks, the pressure block 17 can be used to quickly tap the square bricks at a certain frequency to ensure the compaction of the square bricks. Moreover, the setting of the elastic telescopic mechanism can avoid crushing the square bricks. The operation is simple and the effect is good.

[0022] Specific combination Figure 2 In one embodiment of the present invention, the two crankshafts 10 are connected by a plurality of gear transmissions, and the two crankshafts 10 rotate in opposite directions at the same speed. The output shaft of the first reduction motor 12 is fixedly connected to one end of one of the crankshafts 10.

[0023] Specific combination Figure 1-3 In one embodiment of this utility model, a plurality of guide sleeves 7 are fixedly installed on the top of the support 6, and the vertical rod 8 is rotatably installed in the corresponding guide sleeve 7 to improve the stability of the vertical rod 8 sliding up and down.

[0024] Specific combination Figure 2 and Figure 3 In one embodiment of this utility model, the elastic telescopic mechanism includes a sleeve 13 fixedly installed at the bottom end of the vertical rod 8. A sliding rod 16 is slidably installed at the bottom end of the sleeve 13. The bottom end of the sliding rod 16 is fixedly connected to the pressure block 17. The top end of the sliding rod 16 is inserted into the sleeve 13 and then fixedly connected to a slider 15. A spring 14 is provided inside the sleeve 13. The spring 14 is located above the slider 15. A rubber pad 18 is fixedly installed at the bottom of the pressure block 17.

[0025] By setting the rubber pad 18, rigid collision between the pressure block 17 and the square brick can be avoided, thus preventing damage to the square brick. Through the cooperation of the spring 14 and the slider 15, when the rubber pad 18 contacts the square brick 17 and the sleeve 13 continues to move downward under the action of the vertical rod 8, the slider 15 will move upward inside the sleeve 13 to compress the spring 14, thereby avoiding excessive squeezing of the square brick 17.

[0026] Specific combination Figure 1 and Figure 2 In one embodiment of this utility model, the brushing mechanism includes a connecting plate 22. The base plate 1 is connected to the connecting plate 22 via a lifting mechanism. Two rotating shafts 23 are rotatably mounted on the connecting plate 22. A housing 25 is fixedly mounted on the top of the connecting plate 22. The two rotating shafts 23 are connected to the outer wall of the housing 25 via multiple gear transmissions, and the two rotating shafts 23 rotate in opposite directions at the same speed. A brush disc 24 is fixedly mounted on the bottom end of the rotating shaft 23. A second reduction motor 26 is fixedly mounted on the top of the housing 25. The output shaft of the second reduction motor 26 is fixedly connected to the top end of one of the rotating shafts 23.

[0027] By starting the second reduction motor 26, the two rotating shafts 23 can be driven to rotate in opposite directions simultaneously, thereby sweeping the sand spread on the surface of the bricks and sweeping the sand into the gaps between adjacent bricks, reducing the amount of manual sweeping work.

[0028] Specific combination Figure 1 and Figure 2 Based on the previous embodiment, the lifting mechanism further includes a bracket 19 fixedly installed on the top of the base plate 1, an electric cylinder 20 fixedly installed on the top of the bracket 19, a connecting plate 22 fixedly connected to the push rod end of the electric cylinder 20, and a plurality of guide rods 21 slidably installed on the top of the bracket 19, the bottom end of the guide rods 21 being fixedly connected to the connecting plate 22.

[0029] By activating the electric cylinder 20, the connecting plate 22 can be moved up and down, so that the brush plate 24 can be lifted off the ground when not in use, thus facilitating the movement of the device.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
