Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a cement concrete paving equipment for municipal road construction. Background Technology

[0002] Municipal road construction refers to a series of engineering construction activities in urban or town areas, including the construction, reconstruction, expansion or repair of roads used for public transportation, pedestrians and municipal facilities. In order to ensure the smoothness of the road surface, appropriate paving equipment is usually selected for paving operations, such as long slab scrapers.

[0003] In the prior art, Chinese Patent Publication No. CN221855200U discloses an artificial leveling device for asphalt concrete paving, which includes a semi-circular leveling body and an operating rod fixedly connected to the leveling body. The front end of the leveling body is provided with a toothed groove structure along its length, and the rear end of the leveling body is a straight section, which can greatly improve the leveling effect during artificial asphalt pavement paving and improve work efficiency.

[0004] While the aforementioned technologies have made some improvements, a single type of scraper often struggles to meet the diverse needs of concrete paving under different working conditions. For example, curved scrapers can better conform to the road surface contour at road edges or in irregularly shaped areas. However, in large-area flat paving operations, square scrapers, due to their larger contact area and regular shape, require the removal of other scrapers or the loosening of corresponding bolts to disassemble and replace them with new ones, making the overall operation quite cumbersome. Therefore, a cement concrete paving equipment for municipal road construction is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cement concrete paving equipment for municipal road construction, which aims to improve the problem of cumbersome operation when different models of scrapers need to be replaced in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cement concrete paving equipment for municipal road construction, comprising a support column, a connecting box rotatably connected to the bottom end of the support column, and a switching mechanism provided on the inner wall of the front end of the connecting box;

[0007] The switching mechanism includes a rotating column, a limiting block is rotatably connected to the front end of the connecting box, a plug-in plate is elastically connected to the inner wall of the limiting block by a connecting spring, a connecting plate is fixedly connected to the outer arc surface of the rotating column, an arc-shaped scraper is rotatably connected to the right end of the connecting plate, a square scraper is rotatably connected to the left end of the connecting plate, and a fixing mechanism is provided at the front end of the support column.

[0008] As a further description of the above technical solution:

[0009] The outer arc surface of the rotating column is rotatably connected to the inner wall of the front end of the connecting box.

[0010] As a further description of the above technical solution:

[0011] One end of the connecting spring is fixedly connected to the outer wall of the plug-in plate, and the other end of the connecting spring is fixedly connected to the inner wall of the limiting block. The outer wall of the plug-in plate passes through and is slidably connected to the inner wall of the limiting block. The bottom outer wall of the plug-in plate is inserted into the inner wall of the rotating column.

[0012] As a further description of the above technical solution:

[0013] Guide rods are fixedly connected to both the left and right sides of the inner wall of the connecting box, and the inner walls of the square scraper and the arc-shaped scraper are slidably connected to the outer arc surface of the guide rods.

[0014] As a further description of the above technical solution:

[0015] The connecting plate is a telescopic plate.

[0016] As a further description of the above technical solution:

[0017] The fixing mechanism includes a fixing block, a positioning block is fixedly connected to the top of the connecting box, a moving plate is slidably connected to the inner wall of the positioning block, a magnet is fixedly connected to the inner wall of the moving plate, and a magnetic block is fixedly connected to the inner wall of the fixing block.

[0018] As a further description of the above technical solution:

[0020] As a further description of the above technical solution:

[0021] The rear end of the magnet is magnetically connected to the outer wall of the magnetic block.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, through the cooperation between the supporting column, connecting box and its switching mechanism, when the scraper needs to be switched, the two sets of plug-in plates are pinched inward, and then the limiting block is flipped to release the limiting of the rotating column. Then the rotating column can be rotated to switch between the arc-shaped scraper and the square scraper, thereby achieving the purpose of rapid switching. The overall operation is relatively simple and convenient.

[0024] 2. In this utility model, through the mutual cooperation between the fixed mechanism and other structures, when the connecting box needs to be stored and folded, the connecting box is flipped over so that the fixed block contacts the inclined surface of the moving plate. Then, due to the magnetism of the magnetic block and the magnet, the moving plate will reset and insert into the fixed block. Furthermore, the magnetism of the magnetic block and the magnet makes the moving plate more stable after insertion. Attached Figure Description

[0033] 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.

[0034] Reference Figures 1-2 The present invention provides an embodiment of a cement concrete paving device for municipal road construction, comprising a support column 1, with a connecting box 2 rotatably connected to the bottom end of the support column 1. The support column 1 is designed to facilitate manual hand-held use of the entire device for cement concrete paving operations during municipal road construction. A switching mechanism 3 is provided on the inner wall of the front end of the connecting box 2. The switching mechanism 3 enables the quick selection of a suitable scraper.

[0035] Reference Figures 2-4 The switching mechanism 3 includes a rotating column 302. The rotation of the rotating column 302 enables the switching mechanism 3 to be used. The front end of the connecting box 2 is rotatably connected to a limit block 303. The limit block 303 can limit and fix the rotating column 302. The inner wall of the limit block 303 is elastically connected to a plug plate 305 through a connecting spring 304. There are two sets of plug plates 305, both of which are L-shaped and staggered. The outer arc surface of the rotating column 302 is fixedly connected to a connecting plate 307. The two have the same movement trajectory. The right end of the connecting plate 307 is rotatably connected to an arc-shaped scraper 301, and the left end of the connecting plate 307 is rotatably connected to a square scraper 306. The rotation of the connecting plate 307 causes the arc-shaped scraper 301 and the square scraper 306 to switch. The front end of the support column 1 is provided with a fixing mechanism 4. The fixing mechanism 4 can limit the folded connecting box 2 and prevent rotation.

[0036] Reference Figures 2-4 The outer arc surface of the rotating column 302 is rotatably connected to the inner wall of the front end of the connecting box 2. This rotatable design facilitates manual operation. One end of the connecting spring 304 is fixedly connected to the outer wall of the plug-in plate 305, and the other end is fixedly connected to the inner wall of the limiting block 303. The outer wall of the plug-in plate 305 is slidably connected to the inner wall of the limiting block 303. The elasticity of the connecting spring 304 allows the plug-in plate 305 to perform both resetting and limiting functions. Furthermore, the plug-in plate 305 can only move horizontally. A horizontal plate is provided at the top of the plug-in plate 305 to reduce dust entry into the limiting block 303. The bottom outer wall of the plug-in plate 305 is plugged into the inner wall of the rotating column 302. The inner side of the rotating column 302 has a plug-in hole. The plug-in plate 305 is plugged into the plug-in hole to complete the fixing operation. The left and right sides of the inner wall of the connecting box 2 are fixedly connected with guide rods 308. The inner walls of the square scraper 306 and the arc scraper 301 are slidably connected to the outer arc surface of the guide rod 308. The guide rod 308 can guide the square scraper 306 and the arc scraper 301 to a certain extent, so that they can only move vertically. The connecting plate 307 is a telescopic plate. The telescopic plate can avoid motion interference during rotation.

[0037] Reference Figure 2 , Figure 5and Figure 6 The fixing mechanism 4 includes a fixing block 401. A positioning block 402 is fixedly connected to the top of the connecting box 2. A movable plate 403 is slidably connected to the inner wall of the positioning block 402. The movable plate 403 has an inclined surface on the side near the fixing block 401, with the inclined surface facing upwards. The inclined surface facilitates insertion and fixing. A magnet 405 is fixedly connected to the inner wall of the movable plate 403. A magnetic block 404 is fixedly connected to the inner wall of the fixing block 401. The magnet 405 and the magnetic block 404 limit and fix the fixing block 401 and its movable plate 403 after they come into contact. The rear end of the fixing block 401 is fixedly connected to the front end of the support column 1. The support column 1 can support the fixing block 401. The rear end of the movable plate 403 contacts the inner wall of the fixing block 401. The two contacts to achieve the purpose of pre-positioning. The rear end of the magnet 405 is magnetically connected to the outer wall of the magnetic block 404. The two are magnetically connected to limit and fix the pre-positioned movable plate 403 and the fixing block 401.

[0038] Working principle: When paving cement concrete during municipal road construction, the operator holds the support column 1 and moves the equipment to the paving position. When it is necessary to switch scrapers, the two sets of plug-in plates 305 are first moved towards the middle. When the plug-in plates 305 move inward, they will compress the connecting spring 304. When they move to a certain extent, the bottom end of the plug-in plate 305 can easily disengage from the inner wall of the rotating column 302, thereby releasing the plug. Then, the limit block 303 is rotated upward, which can apply external force to the rotating column 302 to make it rotate. The rotation of the rotating column 302 drives the connecting plate 307 to rotate. Since the right end of the connecting plate 307 is connected to the arc-shaped scraper 301 and the left end is connected to the square scraper 306, and the connecting plate 307 rotates under the guidance of the guide rod 308 (the inner walls of the square scraper 306 and the arc-shaped scraper 301 slide along the outer arc surface of the guide rod 308 and can only move vertically), the arc-shaped scraper 301 and the square scraper 306 can be switched.

[0039] When the connecting box 2 needs to be folded, it is folded upwards. The moving plate 403 will slide. When the connecting box 2 is also in a vertical state, the fixing block 401 and the positioning block 402 are on the same horizontal plane. At this time, the magnet 405 on the inner wall of the moving plate 403 is magnetically connected to the magnetic block 404 on the inner wall of the fixing block 401, and they attract each other, causing the moving plate 403 to move towards the side of the fixing block 401. When it moves to the position, the magnetic block 404 and the magnet 405 are set to limit and fix it, thereby limiting the folded connecting box 2 and preventing it from rotating. This ensures the stability of the equipment in different states, so as to better carry out cement concrete paving operations or equipment storage, transfer and other operations.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
