Description

Technical Field

[0001] This utility model relates to the field of construction machinery technology, specifically to a suspended platform for construction. Background Technology

[0002] The demand for exterior decoration, maintenance and cleaning operations for high-rise buildings, large stadiums and other projects is increasing, and high-altitude work equipment has become a key tool in the construction process. Among them, suspended platforms have quickly become the mainstream equipment for high-altitude operations due to their lightweight structure, flexible mobility and low operating costs.

[0003] However, in the use of existing technology, suspended platforms are often raised and fixed in position by steel cables. During long-term and high-frequency use, the steel cables need to continuously contact and rub against the guide components such as the limit wheels of the suspended platform. If the steel cables are not effectively lubricated in time, the frictional resistance between the steel cables and the limit wheels will increase significantly. This not only increases the energy consumption during the lifting and lowering of the suspended platform, but also causes the wear of the steel wires on the surface of the steel cables to be aggravated, resulting in phenomena such as broken wires and corrosion, thus shortening the service life of the steel cables. Therefore, a suspended platform for construction is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a suspended platform for building construction, in order to solve the problem mentioned in the background art that the suspended platform is usually raised and fixed in position by steel cables. During long-term and high-frequency use, the steel cables need to continuously contact and rub against the guide components such as the limiting wheels of the suspended platform. If the steel cables are not effectively lubricated in time, the frictional resistance between the steel cables and the limiting wheels will increase significantly. This not only leads to increased energy consumption during the lifting and lowering of the suspended platform, but also causes accelerated wear of the steel wires on the surface of the steel cables, resulting in phenomena such as broken wires and corrosion, thus shortening the service life of the steel cables.

The inside of the guide tube is connected to the inside of the oil injection groove, and the outer surface of the guide tube away from the oil injection groove is in contact with the inside of the lubrication block.

[0010] Preferably, an oil injection pipe is fixedly connected between the two oil injection grooves, and the end of the oil injection pipe away from the oil injection groove is connected to the interior of the chute.

[0016] Please see Figure 1-6 The present invention provides a technical solution: a suspended platform for construction, comprising a device body 1, a fixed frame 2 fixedly connected to the upper surface of the device body 1, a second limiting wheel 15 rotatably connected inside the fixed frame 2, the fixed frame 2 providing installation space for the second limiting wheel 15, a first sprocket 3 fixedly connected to one end of the second limiting wheel 15, a lead screw 21 rotatably connected inside the fixed frame 2, a second sprocket 4 fixedly connected to one end of the lead screw 21, the outer surface of the second sprocket 4 and the outer surface of the first sprocket 3 being driven by a chain, the second limiting wheel 15 driving the lead screw 21 to rotate through the chain transmission between the first sprocket 3 and the second sprocket 4.

[0017] The fixed frame 2 has a groove 16 inside, and a piston 20 is slidably connected inside the groove 16. A limiting block 17 in a circular array is fixedly connected to the outer surface of the piston 20. The outer surface of the limiting block 17 is in contact with the inner wall of the groove 16. The groove 16 serves to limit the position of the limiting block 17 and the piston 20. A groove 23 is provided on the back of the piston 20. A flexible paddle 18 is fixedly connected to the back of the piston 20. The edge of the flexible paddle 18 is in contact with the inner wall of the groove 23. A notch in a circular array is provided on the surface of the piston 20. The contact between the groove 23 and the flexible paddle 18 enables the flexible paddle 18 to achieve a one-way seal on the piston 20, allowing lubricating oil to enter the groove 16 through the reciprocating movement of the piston 20.

[0018] The fixed frame 2 has an oil storage tank 14 fixedly connected inside, and the upper surface of the oil storage tank 14 is fixedly connected to the feeding pipe 5. The oil storage tank 14 serves to store lubricating oil.

[0019] The fixed frame 2 is equipped with a one-way valve 19. The input end of the one-way valve 19 is connected to the inside of the oil reservoir 14, and the output end of the one-way valve 19 is connected to the inside of the slide groove 16. Through the one-way valve 19, the lubricating oil inside the oil reservoir 14 flows into the slide groove 16 in one direction.

[0020] The mounting bracket 2 has two mounting slots 13 inside, and each mounting slot 13 is equipped with a lubricating block 12. A cleaning block 6 is provided on the upper surface of the mounting bracket 2 near the mounting slot 13. The exposed parts are cleaned by the cleaning block 6.

[0021] The fixed frame 2 has an oil filling groove 22 located inside the fixed groove 13. The fixed groove 13 has a linearly arranged guide tube 24 fixedly connected inside. The inside of the guide tube 24 is connected to the inside of the oil filling groove 22. The outer surface of the guide tube 24 away from the oil filling groove 22 is in contact with the inside of the lubrication block 12. The guide tube 24 is used to transport the lubricating oil inside the oil filling groove 22 into the middle position of the lubrication block 12 for efficient lubrication of the subsequent devices.

[0022] An oil injection pipe 7 is fixedly connected between the two oil injection grooves 22. The end of the oil injection pipe 7 away from the oil injection groove 22 is connected to the inside of the slide groove 16. The oil injection pipe 7 is used to introduce the lubricating oil inside the slide groove 16 into the oil injection groove 22.

[0023] The bottom of the two fixed slots 13 are fixedly connected to oil return pipes 9, and a filter 10 is provided on the back of the fixed frame 2. The input end of the filter 10 is fixedly connected to the surface of the oil return pipe 9, and the output end of the oil return pipe 9 is fixedly connected to the inside of the oil storage tank 14. The lubricating oil that has settled to the bottom inside the fixed slots 13 is transported into the filter 10 through the oil return pipe 9. The filter 10 is used to filter the lubricating oil, and the filtered lubricating oil is transported back into the oil storage tank 14, so that the lubricating oil can be recycled, thereby reducing the waste of lubricating oil.

[0024] The fixing frame 2 has two first limiting wheels 11 rotatably connected inside. The surfaces of the two first limiting wheels 11 are provided with steel cables 8. The surface of the steel cables 8 is in contact with the surface of the second limiting wheel 15. The outer surface of the steel cables 8 is in contact with the interior of the cleaning block 6. The interior of the lubrication block 12 is in contact with the outer surface of the steel cables 8. The two first limiting wheels 11 and the second limiting wheels 15 are used to support the position of the steel cables 8. The cleaning block 6 cleans the impurities on the surface of the steel cables 8, while the lubrication block 12 lubricates and wipes the surface of the steel cables 8.

[0025] Working principle: During use, the steel cable 8 is moved by an external device, causing it to move across the surfaces of the first limiting wheel 11 and the second limiting wheel 15. During this process, the surface of the steel cable 8 rubs against the surface of the cleaning block 6, allowing the cleaning block 6 to wipe away impurities from the surface of the steel cable 8, preventing external impurities from entering the interior of the fixing frame 2. This increases the wear on the steel cable 8 when it comes into contact with the first limiting wheel 11. Simultaneously, the steel cable 8 drives the second limiting wheel 15 to rotate, causing the second limiting wheel 15 to... The first sprocket 3 is driven to rotate, which in turn drives the second sprocket 4 and the lead screw 21 to rotate via chain transmission. This causes the lead screw 21 to engage in helical transmission with the inside of the piston 20, allowing the piston 20 and the limiting block 17 to slide back and forth on the surface of the lead screw 21 under the limiting action of the sliding groove 16. When the piston 20 drives the flexible paddle 18 to move towards the back of the fixed frame 2, the flexible paddle 18 comes into close contact with the inner wall of the groove 23, creating a negative pressure state at one end of the front of the sliding groove 16. This forces the lubricating oil inside the oil tank 14 to pass through the one-way valve 1. 9. When the piston 20 moves in the reverse direction, under the one-way flow limiting action of the one-way valve 19, the lubricating oil passes through the notch on the surface of the piston 20 and squeezes the flexible paddle 18, causing the edge of the flexible paddle 18 to separate from the groove 23. This allows the lubricating oil to pass through the notch on the surface of the piston 20 and enter the other end of the slide groove 16. When the piston 20 moves back towards the back of the fixed bracket 2 again, the lubricating oil is transported into the oil injection groove 22 through the oil injection pipe 7, and further transported to the interior of the lubrication block 12 near the guide pipe 24. The position of the steel cable 8: When the steel cable 8 slides inside the lubricating block 12, it is wiped by the lubricating oil inside the lubricating block 12, so that an oil film is formed on the surface of the steel cable 8, reducing the friction between the steel cable 8 and the first limiting wheel 11 and the second limiting wheel 15. Then, more lubricating oil moves to the bottom of the fixed groove 13 and finally enters the filter 10 through the oil return pipe 9. The filter 10 filters the lubricating oil, and the filtered lubricating oil is finally transported into the oil storage tank 14 for the next use.
