Description

Technical Field

[0001] The present invention relates to the technical field of silo technology, and specifically, to a formwork device for improving the surface quality of large-diameter silos. Background Art

[0002] Large-diameter reinforced concrete silos are important storage facilities in industries such as coal mines, mines, and grain storage. With the development of social economy, the required diameter of silos is getting larger and larger. When constructing large-diameter silos, slip form construction technology is mostly used. During slip form construction, multiple support rods are set up in advance, and a platform is built to pull the entire platform up through a hydraulic system on the support rods. An inner form and an outer form are set on the platform, and concrete is poured between the inner form and the outer form. At the same time, the platform is slowly lifted, and the concrete gradually hardens after separating from the inner form and the outer form.

[0003] Usually, two layers of areas for workers to move are set on the platform. Workers on the upper platform carry out cement pouring, and workers on the lower platform carry out leveling treatment on the surface of the silo. However, the leveling range by the workers' leveling treatment is small, and the leveling speed is slow. Since the platform needs to rise as a whole, due to the differences in the gas flow velocity and sunlight irradiation area in each direction, different parts of the silo in different directions have different hardening speeds. The traditional manual leveling is prone to problems such as deformation on the surface of the parts with slower hardening due to different hardening degrees of each part. Summary of the Invention

[0004] The present invention provides a formwork device for improving the surface quality of large-diameter silos, which is used to solve the problem that different positions on large-diameter silos in the prior art may have different hardening speeds due to uneven light and air flow, resulting in easy deformation of the surface.

A jack 4 is fixedly installed on the support frame 3. The jack 4 is slidably arranged on the support rod 1. An operation platform 5 is fixedly installed on the support frame 3. The support rod 1 penetrates through the operation platform 5. The support frame 3 is arranged above the silo wall 2. The inner formwork 6 is fixedly connected to the support frame 3.

The plurality of independent treatment mechanisms are fixedly connected to the support frame 3. The plurality of independent treatment mechanisms are arranged around the silo wall 2. Each independent treatment mechanism is provided with a multi-stage leveling mechanism. The independent treatment mechanism is used to drive the multi-stage leveling mechanism to perform a lifting movement. The multi-stage leveling mechanism is used to perform multi-stage and multiple leveling treatments on the silo wall 2, and at the same time, it can detect the change in the hardness of the concrete. In this embodiment, the support frame 3 is set to ten independent parts, which are respectively driven to rise by the jack 4, and are leveled by a total of twenty independent treatment mechanisms and multi-stage leveling mechanisms on the inner and outer sides for different positions, so as to perform treatment on the positions that need to be treated on the surface while maintaining the rising speed of the operation platform 5.

[0029] As Figures 1 to 3 shown, some of the independent treatment mechanisms are arranged inside the silo wall 2, and the rest of the independent treatment mechanisms are arranged outside the silo wall 2. The independent treatment mechanisms inside the silo wall 2 correspond to those outside the silo wall 2 one by one. The multi-stage leveling mechanism includes an inner leveling component and an outer leveling component. The inner leveling component is rotatably arranged on the independent treatment mechanism inside the silo wall 2. The inner leveling component is used to level the inner surface of the silo wall 2. The outer leveling component is rotatably arranged on the independent treatment mechanism outside the silo wall 2. The outer leveling component is used to level the outer surface of the silo wall 2.

[0030] As Figures 1 to 3As shown in the figure, the independent processing mechanism includes a vertical track 8, a first driving cylinder 9, a scraping frame 10 and a linkage assembly. The vertical track 8 is fixedly installed on the support frame 3. An opening is formed on one side of the vertical track 8 facing the silo wall 2. The first driving cylinder 9 is fixedly installed on the support frame 3. The first driving cylinder 9 is arranged on one side of the vertical track 8 close to the silo wall 2. The scraping frame 10 is slidably arranged on the vertical track 8. The scraping frame 10 is fixedly connected to the output end of the first driving cylinder 9. The inner scraping assembly is slidably connected to the scraping frame 10 arranged inside the silo wall 2. The outer scraping assembly is slidably connected to the scraping frame 10 arranged outside the silo wall 2. The linkage assembly is arranged on the scraping frame 10. The linkage assembly is used to drive the inner scraping assembly or the outer scraping assembly to move. The linkage assembly includes a second driving cylinder 20 and a linkage frame 21. The second driving cylinder 20 is rotatably connected to the scraping frame 10. The output end of the second driving cylinder 20 is rotatably connected to the linkage frame 21. The linkage frame 21 arranged inside the silo wall 2 is rotatably connected to a plurality of first scraping plates 14. The linkage frame 21 arranged outside the silo wall 2 is rotatably connected to a plurality of second scraping plates 16. The output end of the first driving cylinder 9 can drive the scraping frame 10 to move in the vertical direction. The telescopic movement of the output end of the second driving cylinder 20 can control the movement of the linkage frame 21, thereby driving a plurality of first scraping plates 14 or second scraping plates 16 to rotate at one time.

[0031] As Figure 3 and Figure 6 shown in the figure, an arc plate 11 and a leak-proof plate 12 are arranged on the scraping frame 10. There are a plurality of arc plates 11. The plurality of arc plates 11 are fixedly connected to the scraping frame 10. The leak-proof plate 12 corresponds to the arc plate 11 one by one. The leak-proof plate 12 is fixedly connected to the scraping frame 10. The leak-proof plate 12 is arranged above the arc plate 11. When the first scraping plate 14 and the second scraping plate 16 slide, they may scrape off the excess concrete. The leak-proof plate 12 can prevent the concrete debris from falling into the gap between the first arc frame 13 or the second arc frame 15 and the arc plate 11.

[0032] As Figures 3 to 6As shown in the figure, the inner leveling assembly includes a first arc-shaped frame 13 and a first scraping plate 14. There are multiple first arc-shaped frames 13. The arc-shaped plate 11 passes through the first arc-shaped frame 13, and the first arc-shaped frame 13 is slidably connected to the arc-shaped plate 11. The first scraping plate 14 is arc-shaped. A first scraping plate 14 is fixedly connected to each first arc-shaped frame 13. The first scraping plate 14 is in contact with the inner side of the silo wall 2. The multiple first scraping plates 14 are vertically arranged on the scraping frame 10. In this embodiment, there are three first scraping plates 14. The outer leveling assembly includes a second arc-shaped frame 15 and a second scraping plate 16. There are multiple second arc-shaped frames 15. The arc-shaped plate 11 passes through the second arc-shaped frame 15, and the second arc-shaped frame 15 is slidably connected to the arc-shaped plate 11. The second scraping plate 16 is arc-shaped. A second scraping plate 16 is fixedly connected to each second arc-shaped frame 15. The second scraping plate 16 is in contact with the outer side of the silo wall 2. The multiple second scraping plates 16 are vertically arranged on the scraping frame 10. In this embodiment, there are three second scraping plates 16.

[0033] As Figures 4 to 6 shown, arc-shaped surfaces 17 are provided on the lower sides of the first scraping plate 14 and the second scraping plate 16. When the first scraping plate 14 and the second scraping plate 16 are coaxial with the silo wall 2, the side of the first scraping plate 14 away from the first arc-shaped frame 13 is in contact with the inner side of the silo wall 2, and the side of the second scraping plate 16 away from the second arc-shaped frame 15 is in contact with the outer side of the silo wall 2. When the first scraping plate 14 and the second scraping plate 16 rotate, the arc-shaped surfaces 17 are in contact with the silo wall 2. From top to bottom, the distances between the arc-shaped surfaces 17 on the multiple first scraping plates 14 and the silo wall 2 decrease in sequence, and the distances between the arc-shaped surfaces 17 on the multiple second scraping plates 16 and the silo wall 2 also decrease in sequence. When looking down from above, the upper first scraping plate 14 and the second scraping plate 16 are farther away from the surface of the silo wall 2 than the lower first scraping plate 14 and the second scraping plate 16. When the scraping frame 10 drives the inclined first scraping plate 14 and the second scraping plate 16 to rise, the concrete on the surface of the silo wall 2 is leveled from top to bottom, avoiding the situation that the concrete hardens slowly and flows. The multi-stage sequential leveling is beneficial to push the concrete to the position where it should be, avoiding the situation that the direct pushing affects the distribution of the concrete. After the concrete is leveled through the inclined state, the first scraping plate 14 and the second scraping plate 16 can be rotated to the vertical state. On the one hand, the surface of the silo wall 2 can be leveled by sliding in the vertical direction, and the position of the concrete forming can also be adjusted. The first scraping plates 14 and the second scraping plates 16 on both sides can be kept vertical to clamp the silo wall 2.

[0034] As Figures 4 to 5As shown, an extension scraper 18 is fixedly connected to the side of the second scraping plate 16 near the support frame 3. In this embodiment, the extension scraper 18 is arranged on the right side of the second scraping plate 16. When the second scraping plate 16 rotates to a vertical state and the second scraping plate 16 on the right side remains in an inclined state, the extension scraper 18 contacts the silo wall 2. When the second scraping plate 16 moves, it can scrape flat the position on the silo wall 2 between adjacent second scraping plates 16, or scrape off the excess concrete.

[0035] As Figures 4 to 6 As shown, a plurality of temperature measuring components 19 are arranged on both the first scraping plate 14 and the second scraping plate 16. In this embodiment, the temperature measuring components 19 are arranged on both sides of the first scraping plate 14 and the second scraping plate 16. Through the temperature change of the concrete from top to bottom, the degree of hydration reaction of the concrete can be measured, and then the degree of concrete solidification can be judged.

[0036] In this embodiment, the support frame 3 is lifted and lowered by the lifting of the jack 4 on the support rod 1, and the concrete is poured between the inner formwork 6 and the outer formwork 7 for shaping. When there is a situation where the concrete in some positions is not hard enough and deformed after separating from the inner formwork 6 and the outer formwork 7, the output end of the first driving cylinder 9 pushes the scraping frame 10 to slide to a specified position on the vertical track 8, and the output end of the second driving cylinder 20 shortens to pull the linkage frame 21. The linkage frame 21 simultaneously drives a plurality of scraping frames 10 one or a plurality of scraping frames 10 two to rotate to an inclined state. At this time, the output end of the first driving cylinder 9 shortens to pull the scraping frame 10 upward, so that the arc surface 17 scrapes the silo wall 2 flat. The output end of the second driving cylinder 20 elongates to push the linkage frame 21, so that the scraping frame 10 one or the scraping frame 10 two rotates to a vertical state to scrape the surface of the silo wall 2 flat.

[0037] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
