Description

Technical Field

[0001] This utility model relates to the field of highway engineering technology, and in particular to a highway compaction device for highway engineering. Background Technology

[0002] With economic development and accelerated urbanization, the demand for highway infrastructure is constantly increasing in various countries, and the scale of highway construction is expanding daily. In order to ensure the quality and service life of highways, it is necessary to effectively compact the roadbed and pavement to improve their density and stability, which has prompted the continuous development and improvement of highway compaction devices.

[0003] In the existing technology, the existing highway compaction device for highway engineering has a relatively slow compaction speed. Because the area compacted each time is small, repeated operation is required. Especially in large-area highway compaction operations, it may take a long time to complete the task, which is not very practical. In addition, the existing highway compaction device for highway engineering produces a lot of dust during compaction, which is harmful to the health of workers, making it not very practical. Utility Model Content

[0004] This utility model mainly provides a highway compaction device for highway engineering that can expand the compaction area and suppress splashed dust with water mist.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a highway compaction device for highway engineering, comprising a main board, a bracket fixed to the top of the main board, a hydraulic push rod installed at the bottom of the bracket, a first pressing plate fixed to the output end of the hydraulic push rod, a rotating shaft rotatably connected to both ends of the first pressing plate, a connecting block fixed to the outer wall of the rotating shaft, a second pressing plate matching the first pressing plate fixed to the end of the connecting block away from the rotating shaft, a water storage tank fixed to the top of the main board, a top cover provided at the top of the water storage tank, a snap-fit ​​structure for installing and removing the top cover provided on the outer wall of the water storage tank, a water pump installed at the top of the top cover, a connecting pipe fixed to the top of the water pump, a water outlet pipe fixed to the top of the connecting pipe, and multiple atomizing nozzles installed on the outer wall of the water outlet pipe.

[0006] Preferably, the buckle structure includes a fixing frame fixed to the outer wall of the water tank, a locking post slidably connected inside the fixing frame, one end of the locking post penetrating the top cover and located inside the water tank, and a pull block fixed to the other end of the locking post. A spring is fixed between the pull block and the fixing frame on the outside of the locking post. By stretching the spring, the locking post connected to the pull block will move, allowing it to penetrate the top cover and be inserted into the water tank, thereby limiting the position of the top cover and achieving the effect of installing the top cover. When the user pulls the pull block, causing the locking post to detach from the water tank, the locking post no longer limits the top cover, and the user can directly lift and remove the top cover.

[0007] Preferably, a limiting plate is fixed on the outer wall of the water storage tank, and a pin is provided inside the pull block. The output end of the pin passes through the limiting plate. By setting the pin and the limiting plate, the position of the pull block can be limited to prevent it from moving accidentally and causing the roller to move accidentally.

[0008] Preferably, both ends of the first pressing plate are provided with connecting grooves that match the rotating shaft and the connecting block. The top of the first pressing plate is provided with a placement groove that matches the second pressing plate at the opposite end of the two connecting grooves. With the setting of the placement groove and the connecting groove, when the second pressing plate is not needed, the user can choose to rotate the two rotating shafts to drive the two second pressing plates connected by the two connecting blocks to be placed into the placement groove, thereby reducing the volume occupied.

[0009] Preferably, the bottom end of the water pump is fixed with an inlet pipe, the bottom end of the inlet pipe passes through the top cover and is located inside the water storage tank, the top end of the top cover is fixed with a water replenishment pipe, and the top end of the water replenishment pipe is threaded with a sealing cap. By setting the water replenishment pipe, the water pump can pump water from the water storage tank, and the water replenishment pipe can replenish water to the water storage tank.

[0010] Preferably, the bottom four corners of the main board are equipped with universal self-locking wheels, the rotating shaft is fixed to the first pressing plate by bolts, and two limiting holes matching the bolts are opened in the rotating shaft. The bolts can be used to position the rotating shaft and prevent it from rotating accidentally. The two limiting holes correspond to the positions of the second pressing plate when it is unfolded and the second pressing plate when it is retracted.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, during compaction, the user rotates two shafts, which in turn rotates two second pressing plates connected by two connecting blocks. This allows the two second pressing plates to expand the pressing area of ​​the first pressing plate, thereby improving the overall compaction effect. The operation of the water pump allows water from the water tank to enter the connecting pipe and the outlet pipe through the inlet pipe, and then be atomized and sprayed out through the atomizing nozzle, which can treat the dust generated during compaction with water mist.

[0020] Please see Figures 1-4This utility model provides a technical solution: a highway compaction device for highway engineering, including a main board 1, a bracket 2 fixed to the top of the main board 1, a hydraulic push rod 3 installed at the bottom of the bracket 2, a first pressing plate 4 fixed to the output end of the hydraulic push rod 3, a rotating shaft 5 rotatably connected to both ends of the first pressing plate 4, a connecting block 6 fixed to the outer wall of the rotating shaft 5, and a second pressing plate 7 matching the first pressing plate 4 fixed to the end of the connecting block 6 away from the rotating shaft 5. A water storage tank 12 is fixed to the top of the main board 1, a top cover 13 is provided at the top of the water storage tank 12, a snap-fit ​​structure 21 for installing and removing the top cover 13 is provided on the outer wall of the water storage tank 12, a water pump 14 is installed at the top of the top cover 13, a connecting pipe 15 is fixed to the top of the water pump 14, and a water outlet pipe 16 is fixed to the top of the connecting pipe 15. Multiple atomizing nozzles 17 are installed on the outer wall. During compaction, the user rotates two rotating shafts 5, which drives the two second pressing plates 7 connected by two connecting blocks 6 to rotate, so that the two second pressing plates 7 can expand the pressing area of ​​the first pressing plate 4, thereby improving the overall compaction effect. Through the operation of the hydraulic push rod 3, the first pressing plate 4 and the second pressing plate 7 can be driven down, thereby pressing and compacting the ground. Through the operation of the water pump 14, the water in the water storage tank 12 can enter the connecting pipe 15 and the outlet pipe 16 through the water inlet pipe 18, and then be atomized and sprayed out through the atomizing nozzles 17, which can treat the dust generated during compaction with water mist. Through the setting of the snap-fit ​​structure 21, the top cover 13 can be installed and removed, which facilitates the cleaning of the inside of the water storage tank 12.

[0021] like Figure 1-4 As shown, the buckle structure 21 includes a fixing frame 2101 fixed to the outer wall of the water tank 12. A locking post 2102 is slidably connected inside the fixing frame 2101. One end of the locking post 2102 passes through the top cover 13 and is located inside the water tank 12. A pull block 2103 is fixed to the other end of the locking post 2102. A spring 2104 is fixed between the pull block 2103 and the fixing frame 2101 on the outside of the locking post 2102. By stretching the spring 2104, the locking post 2102 connected to the pull block 2103 will move, so that it passes through the top cover 13 and is inserted into the water tank 12, thereby limiting the position of the top cover 13 and achieving the effect of installing the top cover 13. When the user pulls the pull block 2103 and causes the locking post 2102 to detach from the water tank 12, the locking post 2102 no longer limits the top cover 13, and the user can directly lift and remove the top cover 13.

[0022] like Figure 1-4 As shown, a limiting plate 22 is fixed on the outer wall of the water storage tank 12, and a pin 23 is provided inside the pull block 2103. The output end of the pin 23 passes through the limiting plate 22. By setting the pin 23 and the limiting plate 22, the position of the pull block 2103 can be limited to prevent it from moving accidentally and causing the roller clamp column 2102 to move accidentally.

[0023] like Figure 1-4 As shown, both ends of the first pressing plate 4 are provided with connecting grooves 11 that match the rotating shaft 5 and the connecting block 6. The top end of the first pressing plate 4, located at the opposite end of the two connecting grooves 11, is provided with a placement groove 10 that matches the second pressing plate 7. With the setting of the placement groove 10 and the connecting groove 11, when the second pressing plate 7 is not needed, the user can choose to rotate the two rotating shafts 5 to drive the two second pressing plates 7 connected by the two connecting blocks 6 to be placed into the placement groove 10, thereby reducing the volume occupied.

[0024] like Figure 1-4 As shown, the bottom end of the water pump 14 is fixed with an inlet pipe 18. The bottom end of the inlet pipe 18 passes through the top cover 13 and is located inside the water storage tank 12. The top end of the top cover 13 is fixed with a water replenishment pipe 19. The top end of the water replenishment pipe 19 is threadedly connected with a sealing cap 20. Through the setting of the water replenishment pipe 19, the water pump 14 can pump water from the water storage tank 12, and the water replenishment pipe 19 can replenish water to the water storage tank 12.

[0025] like Figure 1-4 As shown, universal self-locking wheels 24 are installed at the four corners of the bottom of the main board 1. The rotating shaft 5 is fixed to the first pressing plate 4 by bolts 8. Two limiting holes 9 matching the bolts 8 are opened in the rotating shaft 5. The position of the rotating shaft 5 can be positioned by the bolts 8 to prevent it from rotating accidentally. The two limiting holes 9 correspond to the positions of the second pressing plate 7 when it is unfolded and the second pressing plate 7 when it is retracted.

[0026] The device's operation and working principle are as follows: During compaction, the user rotates two shafts 5, causing the two second pressing plates 7 connected by two connecting blocks 6 to rotate. This expands the pressing area of ​​the first pressing plate 4, improving the overall compaction effect. The hydraulic push rod 3 lowers the first and second pressing plates 4, compacting the ground. The water pump 14 allows water from the storage tank 12 to enter the connecting pipe 15 and the outlet pipe through the inlet pipe 18. Inside the tube 16, the water is atomized and sprayed out through the atomizing nozzle 17, which can treat the dust generated by compaction with water mist. The tension of the spring 2104 will drive the locking post 2102 connected to the pull block 2103 to move, so that it passes through the top cover 13 and is inserted into the water tank 12, thereby limiting the position of the top cover 13 and achieving the effect of installing the top cover 13. When the user pulls the pull block 2103 and causes the locking post 2102 to disengage from the water tank 12, the locking post 2102 no longer limits the top cover 13, and the user can directly lift and remove the top cover 13.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
