Description

Technical Field

[0001] The utility model relates to the technical field of subway construction, in particular to a special leveling device for the arc surface of subway construction. Background Technique

[0002] At present, the subway is a form of railway transportation, referring to an urban rail transit system mainly operating underground, that is, the abbreviation of "subway" or "underground railway". The top of the subway tunnel is arc-shaped. For the sake of beauty and safety, it is necessary to use cement to smear and level the arc-shaped top, so an arc surface leveling device is required.

[0003] By comparing a special leveling device for the arc surface of subway construction with the patent publication number CN221682981U, this device is driven by a rotating motor, and the hollow tube is slidably inserted outside the support rod, so that the hollow tube can move vertically outside the support rod to adjust the position of the leveling arc plate. While ensuring that the leveling arc plate can fit the top of the subway tunnel at different heights, the leveling arc plate can rotate synchronously to perform rotational leveling treatment on the top of the subway tunnel. However, after the leveling arc plate is used, a large amount of concrete particles may adhere to its surface. If it is not cleaned in time, it will solidify on the leveling arc plate, which will reduce the flatness of the surface of the leveling arc plate and cause uneven parts. When used again, it may affect the flatness of the tunnel arc surface and reduce the leveling quality of the arc surface. Content of the Utility Model

The non-slip plate 303 is made of rubber, and a hydraulic cylinder 302 is provided between the non-slip plate 303 and the connection frame 301.

[0029] In this embodiment: The leveling mechanism includes a leveling structure for leveling the tunnel arc surface and a lifting structure for adjusting the height of the leveling structure.

[0030] The lifting structure includes a support column 201 arranged at the center of the bottom plate 100. A lead screw 202 is rotatably installed inside the support column 201. A lifting motor 203 is installed at the rotating end of the lead screw 202. The output end of the lifting motor 203 is fixed to the rotating end of the lead screw 202 through a coupling. A lifting seat 204 is slidably installed inside the support column 201. The lifting seat 204 is threadedly connected to the lead screw 202. A support plate 206 is provided above the support column 201, and a plurality of connecting rods 205 are provided between the support plate 206 and the lifting seat 204.

[0031] The leveling structure includes two symmetrically arranged brackets 207 in the front-rear direction above the support plate 206. A rotating seat 208 is rotatably installed between the two brackets 207. A rotating motor 209 is installed at the rotating end of the rotating seat 208. The output end of the rotating motor 209 is fixed to the rotating end of the rotating seat 208 through a coupling. A leveling plate 212 is fixed to the upper end of the rotating seat 208, and a cleaning structure for cleaning the used leveling plate 212 is provided below the rotating seat 208.

[0032] The cleaning structure includes a scraper 210 arranged between the lower sides of the two brackets 207. The scraper 210 is arc-shaped. Sliding frames 211 are provided between the scraper 210 and the brackets 207. Two symmetrically arranged waste boxes 213 are provided below the scraper 210. A plurality of cleaning rollers 214 are rotatably installed on the surface of the scraper 210. A vibration structure for driving the rotating seat 208 to vibrate when the rotating seat 208 rotates is provided between the rotating seat 208 and the brackets 207.

[0033] The vibration structure includes a plurality of fixed blocks 215 arranged on the front and rear side walls of the rotating seat 208. A plurality of sliding grooves 216 are formed in the lower side of the bracket 207. A convex block 217 is slidably installed in the sliding groove 216. A compression spring is connected between the convex block 217 and the sliding groove 216. One end of the convex block 217 and the fixed block 215 close to each other is arc-shaped and they are slidably matched with each other. After the flat plate 212 levels the arc surface of the subway tunnel, the cleaning structure is used to scrape down the concrete particles adhering to the surface of the flat plate 212. At the same time, when the flat plate 212 rotates, it will generate a certain vibration, which prompts the concrete particles adhering to the surface to fall down by vibration, preventing the concrete particles from solidifying on the surface of the flat plate 212 and affecting the flatness of the surface of the flat plate 212, which will affect the flatness of the tunnel arc surface during subsequent reuse, and improving the quality of the flat plate 212 for leveling the tunnel arc surface.

[0034] Working principle: First, move the device into the subway tunnel. Drive the hydraulic cylinder 302 to drive the two anti-slip plates 303 to move downward, so that the anti-slip plates 303 are in contact with the ground and lift the device upward to support and fix the device. Then drive the lifting motor 203 to drive the lead screw 202 to rotate, drive the lifting seat 204 to move upward, and drive the rotating seat 208 above the support plate 206 to move up to a suitable construction height, so that the surface of the flat plate 212 is in contact with the arc surface of the subway tunnel.

[0035] Then drive the rotating motor 209 to drive the rotating seat 208 to rotate back and forth, drive the flat plate 212 to rotate back and forth to smooth the concrete on the arc surface of the subway tunnel. After leveling, drive the rotating motor 209 to drive the flat plate 212 to rotate to the lower side of the bracket 207. When the flat plate 212 rotates, the surface of the flat plate 212 will be in contact with the end of the scraper 210, so that the end of the scraper 210 scrapes down the concrete particles adhering to the surface of the flat plate 212 into the waste bin 213. Then, in cooperation with the plurality of cleaning rollers 214 on the surface of the flat plate 212, the impurities on the surface of the cleaning rollers 214 are cleaned. Then the flat plate 212 will continue to rotate and retract into the two sliding frames 211 to protect the surface of the flat plate 212 and prevent impurity particles from adhering to the surface of the flat plate 212 again.

[0036] When the rotating seat 208 rotates, a plurality of fixed blocks 215 on the front and rear sides of the rotating seat 208 will squeeze and collide with a plurality of convex blocks 217 on the inner wall of the bracket 207, which will prompt the plurality of convex blocks 217 to strike the rotating seat 208, causing the rotating seat 208 to generate a certain vibration. At this time, the vibration will be transmitted to the flat plate 212, prompting the concrete particles on the surface of the flat plate 212 to fall down into the waste bin 213 by vibration, thereby preventing the concrete particles from solidifying on the surface of the flat plate 212 and affecting the flatness of the surface of the flat plate 212, which will affect the flatness of the tunnel arc surface during subsequent reuse, and improving the quality of the flat plate 212 for leveling the tunnel arc surface.
