Description

Technical Field

[0001] This utility model relates to the technical field of concrete paving equipment, specifically a leveling mechanism for an underground concrete paver. Background Technology

[0002] The purpose of laying concrete on the ground in mines is to use the hardened concrete surface to effectively support underground machinery and transport loads, and to prevent ground cracking caused by rock deformation. A concrete paver is a construction machine that spreads mixed concrete along the roadbed according to predetermined thickness and width requirements, and then completes the concrete pavement construction through steps such as vibration and leveling. However, the leveling mechanism on existing concrete pavers has a simple structure, limited function, and poor leveling effect. Furthermore, concrete tends to adhere to the leveling mechanism during use, and after a certain period of operation, the concrete easily hardens, making the surface of the leveling mechanism uneven and affecting the overall leveling effect.

Detailed Implementation

[0032] 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.

[0033] Example 1

[0034] Please see Figure 1-5 In this embodiment of the utility model, a leveling mechanism for an underground concrete paver includes: a mounting frame 100, a leveling unit 200, and a cleaning unit 300. A fixing plate 110 is fixedly connected to the mounting frame 100. The leveling unit 200 is disposed on the top of one side of the fixing plate 110. The leveling unit 200 includes a movable plate 230, which is disposed on the top of one side of the fixing plate 110. A support component is disposed on the outer side of the movable plate 230. A connecting notch is opened at one end of the movable plate 230, and a rotating block 231 is rotatably connected in the connecting notch. An adjustment component is disposed on the movable plate 230, and a scraping component is disposed at the bottom of the adjustment component. The cleaning unit 300 is disposed on the bottom of one side of the fixing plate 110.

[0035] Specifically, the mounting frame 100 facilitates the installation of the leveling mechanism of the underground concrete paver on the underground concrete paver, and the support assembly supports the moving plate 230. The support assembly also facilitates the adjustment of the position adjustment assembly and the scraping assembly. The position adjustment assembly facilitates the readjustment of the scraping assembly. By adjusting the position of the scraping assembly, the leveling mechanism of the underground concrete paver can be adapted to different underground environments. The scraping assembly facilitates the leveling of the concrete surface, making it more convenient to use. The cleaning unit 300 facilitates the cleaning of the bottom of the scraping assembly, preventing concrete from adhering to the bottom of the scraping assembly from hardening and affecting its use.

[0036] like Figure 2-4As shown, in this embodiment, the support assembly includes a rectangular shell 210 and a screw 220. The rectangular shell 210 is fixedly connected to the top of one side of the fixed plate 110. The movable plate 230 is slidably inserted into the interior of the rectangular shell 210. One end of the screw 220 is rotatably connected to an inner sidewall of the rectangular shell 210. The screw 220 is screwed into the movable plate 230. A stepper motor 221 is provided at one end of the screw 220. The stepper motor 221 is fixedly connected to the rectangular shell 210, and the output end of the stepper motor 221 passes through the rectangular shell 210. The sidewall of the rectangular shell 210 is fixedly connected to one end of the screw 220. The adjustment assembly includes two electric cylinders 240. The bottom of the other end of the rotating block 231 and the moving plate 230 are respectively fixedly connected to the two electric cylinders 240. The output end of the electric cylinder 240 is fixedly connected to a connecting block, and the outer side of the connecting block is rotatably connected to a connecting seat 241. The scraping assembly includes: a connecting shell 250, a placement shell 260, a push plate 280, and a rectangular frame 290. The connecting shell 250 is located at the bottom of the moving plate 230, and the placement shell 260... A push plate 280 is slidably sleeved with the bottom of the connecting shell 250. A first round rod 284 and a second round rod 285 are rotatably sleeved on the push plate 280. Both ends of the first round rod 284 are round blocks 281. A fixing seat 282 is rotatably sleeved on the outer side of each round block 281, and the top of the fixing seat 282 is fixedly connected to the inner top surface of the placement shell 260. A drive motor 283 is provided at one end of the push plate 280, and the drive motor 283 is fixedly connected to the inner top surface of the placement shell 260. The output end of 283 is fixedly connected to the corresponding round block 281. The rectangular frame 290 is fixedly connected to the inner bottom surface of the connecting shell 250. Both ends of the rectangular frame 290 are provided with sliding through holes 291, and both ends of the round rod 285 are slidably connected to the corresponding sliding through holes 291. An L-shaped plate 270 is fixedly connected to one side of the housing 260, and a connecting plate 271 is fixedly connected to the bottom of the L-shaped plate 270. A scraper 272 is fixedly connected to one side of the connecting plate 271, and a fine brush 273 is fixedly connected to the inner top surface of the connecting plate 271.

[0037] The rectangular shell 210 has sliding grooves on both sides of its interior, and the movable plate 230 has protrusions at both ends. The protrusions are slidably connected to the corresponding sliding grooves. The use of the protrusions and sliding grooves in cooperation prevents the movable plate 230 from separating from the screw 220.

[0038] In this embodiment, by starting the stepper motor 221 to rotate forward, the stepper motor 221 drives the screw 220 to rotate, thereby moving the moving plate 230. This facilitates the adjustment of the horizontal position of the positioning component and the scraping component. Furthermore, by activating the two electric cylinders 240, the connecting block and connecting seat 241 are moved, causing the scraping component to move to an appropriate height. This ensures that the bottoms of the connecting shell 250, scraper 272, and fine brush 273 all contact the top of the concrete. When the concrete paver moves the leveling mechanism of the underground concrete paver, the drive motor 283 is started, which drives the circular block 281 and the first circular rod 284 to rotate. When the first circular rod 284 is not located at the center of the circular block 281, the rotating first circular rod 284 will pull the push plate 280 and the second circular rod 285 to move. The placement shell 260 can limit the connection shell 250. When moving, the second circular rod 285 will pull the rectangular frame 29. The 0 and connecting shell 250 move up and down as a whole. During the movement, the two ends of the round rod 285 also slide inside the sliding through hole 291. The connecting shell 250 moves up and down quickly and the distance of the up and down movement is small, so that the connecting shell 250 vibrates. The vibration of the connecting shell 250 makes it easier to beat the top of the concrete, making the concrete below denser and allowing the concrete surface to rise and the cement slurry to float. The moving connecting shell 250 can also scrape the top of the concrete. Then, the fine brush 273 and scraper 272 are used to scrape the top of the concrete multiple times, ensuring the leveling effect of the concrete. If the extension length of the two electric cylinders 240 is controlled to be different, the rotating block 231 can be deflected, which can cause the corresponding electric cylinder 240 to deflect, and thus the scraping component to tilt. By adjusting the scraping component, the leveling unit 200 can be adapted to different working environments in the well, improving the practicality of the leveling mechanism of the underground concrete paver.

[0039] like Figure 4 As shown in this embodiment, heat dissipation holes are provided at both ends of the housing 260.

[0040] In practice, the heat dissipation holes facilitate heat dissipation inside the housing 260, thereby facilitating heat dissipation for the drive motor 283 during operation.

[0041] Example 2

[0042] Based on Embodiment 1, in order to quickly clean the bottom of the connecting shell 250, scraper 272 and fine brush 273 and prevent the concrete adhering to them from solidifying.

[0043] like Figure 5As shown, in this embodiment, the cleaning unit 300 includes a water tank 310 and a drain valve 320. The water tank 310 is fixedly connected to the bottom of one side of the fixing plate 110, and one end of the drain valve 320 is connected and fixed to the water tank 310.

[0044] In practice, a suitable amount of water is stored in the water tank 310. The leveling unit 200 is reset, and the scraping component on the leveling unit 200 is located at the top of the water tank 310. Then, by activating the two electric cylinders 240 to extend, the scraping component moves downward, thereby immersing the connecting shell 250, scraper 272 and fine brush 273 in water. By activating the electric cylinders 240 to reciprocate short distances of extension and retraction, the bottom of the connecting shell 250, scraper 272 and fine brush 273 moves up and down in the water, which facilitates cleaning of the bottom of the connecting shell 250, scraper 272 and fine brush 273 and prevents the concrete adhering to them from hardening and affecting subsequent use. The drain valve 320 is then opened to drain the dirty water inside the water tank 310.

[0045] In order to facilitate the operation of the utility model by the operator, a PLC controller can be set up, and the stepper motor 221, electric cylinder 240 and drive motor 283 are all electrically connected to the PLC controller. The PLC controller is existing technology and will not be described in detail here.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
