Description

Technical Field

[0001] This utility model relates to the field of railway construction technology, and more specifically, to a sliding device for steel-concrete composite beams. Background Technology

[0002] In the prior art, such as the Chinese invention patent with publication number CN118639563B, an automatic sliding device for cast-in-place formwork of simply supported beams is disclosed. This device, through the installation of an anti-foreign-object device, allows an L-shaped frame to drive a U-shaped scraper to scrape off impurities and hardened slurry adhering to the rail surface. This helps restore the flatness of the rail and reduces the bumps and vibrations that the sliding device may encounter during operation. It avoids the problem that scraping off impurities and slurry from the rail surface would cause unevenness and affect the operational stability of the sliding device. Simultaneously, the L-shaped frame, fixed rod, rotating wheel, thin-plate wheel, and sliding plate work together to drive a hammering column to strike the rail surface. The hammering column can effectively loosen the hardened slurry adhering to the rail surface without damaging it, thus facilitating the scraping off of the hardened slurry by the U-shaped scraper. However, the above technical solutions still have the following drawbacks: 1. The hammering column will generate noise pollution during the hammering of the rail; 2. Since the device is usually used in an open-air environment, the rail is constantly exposed to wind, sun and rain erosion, which can easily cause rust, thus reducing the service life of the rail and even creating safety hazards.

Detailed Implementation

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1-2As shown, the embodiment provides a steel-concrete composite beam sliding device, including a sliding track 1, a sliding seat 2, a lifting jack 3, a support platform 4, and a cleaning mechanism 5. The sliding seat 2 is slidably connected to the sliding track 1, and the lifting jack 3 is vertically mounted on the sliding seat 2. The top of the lifting jack 3 is connected to the support platform 4. A cleaning mechanism 5 is also provided on one side of the sliding seat 2. The cleaning mechanism 5 includes a mounting frame 51, an electric push rod 52, a protective cover 53, a grinding belt 54, and a lubrication component 55. The mounting frame 51 is fixed to one side of the sliding seat 2, and the electric push rod 52 is vertically mounted on the mounting frame 51. The output end of the electric push rod 52 is connected to the protective cover 53, and the grinding belt 54 is provided inside the protective cover 53. The lubrication component 55 is provided on the side of the protective cover 53 near the sliding seat 2. In this embodiment, the sliding seat 2 can slide on the sliding track 1, thereby driving the steel-concrete composite beam to move forward quickly to the construction position, facilitating construction operations. The lifting jack 3 is a hydraulic jack that can lift the support platform 4, thereby raising the steel-concrete composite beam synchronously to adjust the position and height of the steel-concrete composite beam. The top surface of the support platform 4 is flat, which increases the contact area. The cleaning mechanism 5 removes rust, concrete debris, and other impurities from the sliding track 1 and lubricates it, thereby reducing the frictional resistance on the sliding seat 2, reducing wear on the sliding track 1, and helping to extend the service life of the device. The mounting bracket 51 is arranged laterally and provides support. The electric push rod 52 is telescopic and controls the up-and-down movement of the protective cover 53, ensuring the bottom surface of the grinding belt 54 presses against the surface of the sliding track 1 to guarantee the grinding effect. The protective cover 53 protects the grinding belt 54. The rotation direction of the grinding belt 54 should be opposite to the forward direction of the sliding seat 2, allowing the grinding belt 54 to remove rust, debris, and other impurities from the surface of the sliding track 1 during rotation, ensuring a clean surface. The lubrication component 55 sprays lubricant onto the surface of the sliding track 1 after grinding to reduce the friction between the sliding seat 2 and the sliding track 1.

[0018] Specifically, the lubrication assembly 55 includes a storage tank 551, a pump body 552, a dust cover 553, a discharge pipe 554, and a nozzle 555. The top of the mounting frame 51 has a storage tank 551 containing lubricant, and the pump body 552 is mounted on the storage tank 551. The bottom of the mounting frame 51 has a dust cover 553, and the nozzle 555 is located inside the dust cover 553. One end of the discharge pipe 554 is connected to the pump body 552, and the other end is connected to the nozzle 555. In this embodiment, the pump body 552 is located on one side of the storage tank 551, enabling it to pump lubricant from the storage tank 551 into the discharge pipe 554, where it is sprayed onto the surface of the sliding track 1 by the nozzle 555. The nozzle 555 is vertically arranged with its nozzle facing downwards. Furthermore, the nozzle 555 is preferably an atomizing nozzle, which can atomize the lubricant and spray it out, so that the droplets are evenly distributed on the sliding track 1.

[0019] Specifically, sponge blocks 556 are provided on both sides of the nozzle 555, and the sponge blocks 556 are connected to the inner wall of the dust cover 553. In this embodiment, the sponge block 556 located on the side of the nozzle 555 closer to the protective cover 53 can sweep away the dust on the sliding track 1, while the other sponge block 556 can smooth out the lubricant, thereby forming a uniform oil film on the surface of the sliding track 1.

[0020] Specifically, an air pump 557 is also provided on the side of the dust cover 553 near the protective cover 53, and an air nozzle 558 is connected to the output end of the air pump 557. In this embodiment, the air nozzle 558 is inclined, and the air pump 557 can generate high-pressure, high-speed airflow, which is blown out by the air nozzle 558, thereby blowing away the dust particles remaining on the surface of the sliding track 1 after polishing, so as to avoid affecting the lubrication effect of the lubricant.

[0021] Specifically, a pressure sensor 56 is also provided on the electric push rod 52. In this embodiment, the pressure sensor 56 is located at the connection between the electric push rod 52 and the protective cover 53, and can monitor the pressure of the grinding belt 54 in real time for easy adjustment.

[0022] Working principle: When the sliding seat 2 slides on the sliding track 1, the cleaning mechanism 5 can remove impurities such as iron filings or stones from the sliding track 1 and apply lubricant to the sliding track 1, thereby reducing the friction force on the sliding seat 2, reducing the wear of the sliding track 1, and improving the service life of the device.
