Description

Technical Field

[0001] This utility model relates to the field of paver technology, specifically to a road surface smoothing device for a slipform paver. Background Technology

[0002] Currently, cement (mud) adheres to the bottom side of the screed of current pavers during use. To prevent this from affecting future use, the bottom side of the screed needs to be cleaned. However, due to structural limitations, the screed cannot be raised to a high enough height, making cleaning extremely inconvenient. Often, the entire screed needs to be removed, which is cumbersome and time-consuming. To address this, CN211897729U discloses a road surface smoothing structure for slipform pavers, relating to the field of paver technology, including a screed control rod. A first fixing plate is fixed to the bottom of the device, and a first fixing rod passes through the side of the first fixing plate. A connecting rod is provided at the end of the first fixing rod, and a second fixing rod passes through one end of the connecting rod. A second fixing plate is fitted onto the end of the second fixing rod. A smoothing sub-plate is fixed to the bottom of the second fixing plate, and spring placement grooves are provided on the left and right sides of the smoothing sub-plate. The push plate, insert plate, and insert plate slots provided by this device can be used to easily fix and separate the smoothing main plate and the smoothing sub-plate. After the smoothing main plate is separated from the smoothing sub-plate, it can be cleaned. The drawback of this slipform paver road smoothing structure is that when cleaning the smoothing main plate, personnel still need to remove the smoothing main plate for cleaning. The removal and cleaning method is still relatively inconvenient and has low work efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a road surface smoothing device for slipform pavers that is easy to operate and has high working efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A road surface smoothing device for a slipform paver includes a connecting frame, a lifting mechanism, a mounting frame, a screed plate, and a scraping and cleaning mechanism.

[0005] As a further improvement to the above technical solution: The scraping and cleaning mechanism includes a connecting rod and a scraper. The top end of the connecting rod is located on a connecting frame, and the scraper is located at the bottom end of the connecting rod and is arranged horizontally. The smearing plate is slidably mounted on a mounting frame. The mounting frame is provided with a sliding drive component, which is connected to the smearing plate and is used to drive the smearing plate to move relative to the scraper. A passage space is formed above the scraper for the smearing plate to pass through.

[0006] The system has two connecting rods, and the two ends of the scraper are respectively connected to the bottom ends of the two connecting rods. The passage space is formed between the two connecting rods.

[0007] The sliding direction of the squeegee is perpendicular to the length direction of the scraper.

[0008] The sliding drive component is a telescopic drive component.

[0009] The top of the smearing plate is provided with a sliding block, which is slidably mounted on the mounting frame and connected to the sliding drive component.

[0010] The trowel plate is fixed to the sliding block by fixing bolts.

[0011] The bottom of the mounting bracket is located on the slide rail, and the sliding block is slidably mounted on the slide rail.

[0012] The lifting mechanism includes a vertical guide rail and a lifting drive component. The top end of the vertical guide rail is fixed on the connecting frame, the mounting frame slides on the vertical guide rail, and the lifting drive component is located between the connecting frame and the mounting frame.

[0013] The lifting drive component is a telescopic drive component.

[0024] Figures 1 to 4This invention illustrates an embodiment of a road surface smoothing device for a slipform paver. The road surface smoothing device for a slipform paver in this embodiment includes a connecting frame 1, a lifting mechanism 2, a mounting frame 3, a smoothing plate 4, and a scraping and cleaning mechanism 5. The connecting frame 1 is used to connect to the slipform paver.

[0025] In use, the connecting frame 1 is connected to the slipform paver, and the slipform paver drives the road surface smoothing device to smooth the road surface. When the mud adhering to the bottom side of the screed plate 4 needs to be cleaned, the scraping and cleaning mechanism 5 moves relative to the screed plate 4 to scrape off the mud. Unlike disassembling the screed plate 4 for cleaning, the screed plate 4 of this road surface smoothing device does not need to be disassembled for cleaning; it can be cleaned directly by the scraping and cleaning mechanism 5, making it convenient to operate and highly efficient.

[0026] Further, in this embodiment, the scraping and cleaning mechanism 5 includes a connecting rod 51 and a scraper 52. The top end of the connecting rod 51 is located on the connecting frame 1, and the scraper 52 is located at the bottom end of the connecting rod 51 and is arranged horizontally. The smearing plate 4 is slidably mounted on the mounting frame 3. The mounting frame 3 is provided with a sliding drive component 6, which is connected to the smearing plate 4 and is used to drive the smearing plate 4 to move relative to the scraper 52. A passage space 7 is formed above the scraper 52 for the smearing plate 4 to pass through. On the one hand, the height of the smearing plate 4 can be adjusted under the lifting action of the lifting mechanism 2 to meet the smearing height requirements. On the other hand, the smearing plate 4 moves relative to the scraper 52 under the driving action of the sliding drive component 6 to scrape off the mud on the bottom side of the smearing plate 4. Specifically, as shown in the figure... Figure 1 As shown, the road surface smoothing device is in its first state, that is, the scraper 52 is located on the right side of the smoothing plate 4 and is higher than the bottom side of the smoothing plate 4 to prevent interference with the smoothing operation of the smoothing plate 4; as Figure 2 As shown, the road surface smoothing device is in the second state, that is, the scraper 52 is located below the smoothing plate 4, and the smoothing plate 4 travels through the passage space 7 under the drive of the sliding drive component 6. The top side of the scraper 52 contacts or approaches the bottom side of the smoothing plate 4 to scrape off the mud on the bottom side of the smoothing plate 4.

[0027] Furthermore, in this embodiment, two connecting rods 51 are provided, and the two ends of the scraper 52 are respectively connected to the bottom ends of the two connecting rods 51, and the passage space 7 is formed between the two connecting rods 51. Specifically, the top end of the connecting rod 51 is fixedly connected to the right side of the connecting frame 1, and the bottom end of the connecting rod 51 extends to the right side of the squeegee 4 in the squeegee working state (horizontally, inclined and / or vertically).

[0028] Furthermore, in this embodiment, the sliding direction of the smearing plate 4 is perpendicular to the length direction of the scraper 52. Preferably, the sliding direction of the smearing plate 4 is the same as the extension and retraction direction of the sliding drive component 6.

[0029] Furthermore, in this embodiment, the sliding drive component 6 is a telescopic drive component, such as a telescopic hydraulic cylinder, a telescopic electric cylinder, or a telescopic pneumatic cylinder.

[0030] Furthermore, in this embodiment, the top of the smearing plate 4 is provided with a sliding block 41, which is slidably mounted on the mounting frame 3 and connected to the sliding drive component 6. Preferably, a connecting seat is provided on the right side of the sliding block 41, one end of the sliding drive component 6 is connected to the mounting frame 3, and the other end is connected to the connecting seat.

[0031] Furthermore, such as Figure 4 As shown, in this embodiment, the squeegee 4 is fixed to the sliding block 41 by fixing bolts 42 for easy assembly and disassembly. Specifically, the top of the squeegee 4 is provided with an internal threaded sleeve, and the fixing bolts 42 are threadedly connected to the internal threaded sleeve. Multiple pairs of internal threaded sleeves and fixing bolts 42 can be provided and connected one-to-one.

[0032] Furthermore, such as Figure 3 As shown, in this embodiment, the bottom of the mounting bracket 3 is located on the slide rail 8, and the sliding block 41 is slidably mounted on the slide rail 8. Preferably, the slide rail 8 is horizontally arranged and perpendicular to the scraper rod 52.

[0033] Furthermore, in this embodiment, the lifting mechanism 2 includes a vertical guide rail 21 and a lifting drive component 22. The top end of the vertical guide rail 21 is fixed on the connecting frame 1, and the mounting frame 3 is slidably mounted on the vertical guide rail 21. The lifting drive component 22 is located between the connecting frame 1 and the mounting frame 3. The lifting drive component 22 drives the mounting frame 3 to move up and down, thereby driving the smoothing plate 4 to adjust its height.

[0034] Furthermore, in this embodiment, the lifting drive component 22 is a telescopic drive component, such as a telescopic hydraulic cylinder, a telescopic electric cylinder, or a telescopic pneumatic cylinder. Preferably, the lifting drive component 22 is vertically arranged and perpendicular to the scraper rod 52.

[0035] Preferably, the mounting frame 3 includes a lifting sleeve 31 and a mounting rod 32. The lifting sleeve 31 is slidably mounted on the vertical guide rail 21. The lifting drive component 22 connects the connecting frame 1 and the lifting sleeve 31. One end of the mounting rod 32 is fixed to the left side of the lifting sleeve 31, and the other end extends to the left side of the sliding block 41 in a direction (horizontal, inclined, and / or vertical) towards the left side of the squeegee 4. One end of the slide rail 8 is fixedly connected to the other end of the mounting rod 32, and the other end extends to the right side of the lifting sleeve 31. The slide rail 8 is located below the lifting sleeve 31. More preferably, in order to reduce the load on the slide rail 8, one end of the sliding drive component 6 is fixedly connected to the mounting frame 3, and the other end is fixedly connected to the connecting seat, so that part of the weight of the sliding block 41 and the squeegee 4 is borne by the sliding drive component 6.

[0036] In other embodiments, the top end of the connecting rod 51 may also be slidably mounted on the connecting frame 1, and a moving drive component is provided on the connecting frame 1 to drive the scraping and cleaning mechanism 5 to move relative to the wiping plate 4. In this way, the extension and retraction length of the sliding drive component 6 can be reduced, and a sliding drive component 6 with a shorter extension and retraction range can be selected.
