Description
Technical Field
[0001] The utility model relates to the technical field of concrete spraying and leveling, and particularly relates to a leveling control device for spraying concrete between piles of a station. Background Technique
[0002] At present, bored cast-in-place piles are often used as the main structure for foundation pit support. On the one hand, the retaining piles play a role in support, and on the other hand, they have the effect of waterproofing. Since the retaining piles are cylindrical, the inner side of the foundation pit needs to be filled with concrete before the construction of the coiled waterproof layer and the structural side wall can be carried out. In the prior art, most of them adopt the method of spraying concrete to fill the retaining piles on one side of the foundation pit. After the foundation pit is excavated to the designed depth, the soil between the piles and on the pile body is cleaned up, and then a wet spraying machine is used to directly spray concrete between the piles and on the pile body. This method is widely used for foundation pits where the coiled waterproof layer is not constructed and the requirement for the clear height is not high. However, during the construction of the station, the requirements for the foundation pit support structure and the waterproof effect of the station are becoming more and more strict.
[0003] However, the existing flatness is controlled by using a benchmark to support and pull a wire, or the construction workers use tools such as a shovel and a scraper to manually level it, so as to ensure the flatness of the sprayed concrete between the piles and improve the smoothness, comfort and safety of the subsequent train operation.
[0004] However, the above-mentioned leveling methods are not only time-consuming and laborious, but also prone to large flatness deviations and cannot control the flatness deviation within a reasonable range. At the same time, the concrete falling during the leveling process will increase the burden and time of the subsequent cleaning work of the construction workers, which is not conducive to the progress of controlling the flatness of the sprayed concrete between the piles. Content of the Utility Model
[0005] The purpose of the utility model is to provide a leveling control device for spraying concrete between piles of a station, which overcomes the problems that the method of controlling the flatness of the sprayed concrete between the piles in the prior art is time-consuming and laborious, it is not easy to control the flatness deviation within a reasonable range, and the concrete falling during the leveling process will increase the burden of the subsequent cleaning work of the construction workers.

[0033] As Figures 1-6 shown, the present utility model provides a device for controlling the smoothness of shotcrete between piles in a station, which includes an arc-shaped housing 1 with an opening to the left. The arc-shaped housing 1 is for facilitating the installation of various components inside it, thereby controlling the smoothness of the concrete surface. And mounting plates 2 connected to the front and rear sides inside the arc-shaped housing 1 by bolts 7. The left end face of the mounting plate 2 is flush with the top of the right side of the arc-shaped housing 1. There are two groups of rolling columns 4 protruding from the left end face of the mounting plate 2 and rotatably connected between the mounting plates 2. The two groups of rolling columns 4 can ensure the movement of the device on the sprayed concrete surface, and at the same time can prevent the arc-shaped housing 1 and the mounting plate 2 from contacting the concrete. A leveling assembly 3 for adjusting the smoothness of shotcrete is provided between the two groups of rolling columns 4 to level the concrete surface during the movement of the device and keep it within the allowable range of smoothness deviation. A collection port 11 is provided at the bottom of the arc-shaped housing 1 to facilitate the collection and treatment of the concrete that falls during the leveling process. A gripping push rod 5 is rotatably connected to the right side of the collection port 11, and the movement of the device can be controlled by the gripping push rod 5.
[0034] In the above solution, the leveling assembly 3 includes a leveling roller 32, a scraping plate 33, and a motor 34. The leveling roller 32 is rotatably connected between the two side mounting plates 2. The rear end of the leveling roller 32 is connected to the output end of the motor 34. The scraping plates 33 are annularly arranged on the outer end face of the leveling roller 32, and the outer end face of the scraping plate 33 is flush with the outer end face of the rolling column 4.
[0035] As an optimized technical solution of the present utility model, a first rotating shaft 31 is rotatably connected to the middle of the mounting plate 2. The first rotating shaft 31 is connected to the output end of the motor 34. The leveling roller 32 is arranged on the first rotating shaft 31. Thus, when the motor 34 drives the first rotating shaft 31 to rotate, the scraping plates 33 arranged in an annular array on its outer surface can be driven to rotate by the leveling roller 32. During the rotation of the scraping plates 33, the concrete on the protruding part of the concrete surface can be scraped to the nearby sunken part to fill the sunken part.
[0036] Meanwhile, an arc-shaped groove is provided at the free end of the scraping plate 33, which can scrape off the excess concrete and then drop it onto the convex edge 13 provided at the bottom of the arc-shaped housing 1. It slides along the convex edge 13 to the collection port 11 and is collected through the pipeline connected to the collection port 11, avoiding the dropped concrete from falling to the ground and increasing the workload of the construction workers.
[0037] During the entire moving process, the rolling column 4 also rotates through the second rotating shaft 41. During the pushing process of the grasping push rod 5, the rolling column 4 will rotate and move under the rotational connection relationship between the second rotating shaft 41 and the mounting plate 2.
[0038] In the above solution, a movable groove 12 is provided at the lower right end of the arc-shaped housing 1. The upper end of the grasping push rod 5 is rotatably connected to the lower end of the sliding groove 12. The upper end of the movable groove 12 is rotatably connected to an auxiliary rod 6, and the lower end of the auxiliary rod 6 is connected to the grasping push rod 5.
[0039] As an optimized technical solution of the present utility model, the upper end of the movable groove 12 is in a horizontal state, the lower side part is in a vertical state, and the included angle with the vertical direction on the left is smaller at the upper end and larger at the lower end, so as to limit the rotation angle of the grasping push rod 5 during the rotation process, enabling the grasping push rod 5 to rotate within a certain range. And the auxiliary rod 6 assists the left sides of the arc-shaped housing 1 and the mounting plate 2 to always fit the concrete surface, thereby facilitating the control of the flatness.
[0040] In the above solution, a sliding groove 51 is opened on the right side of the grasping push rod 5. A guide sliding rod 52 is arranged along the length direction of the grasping push rod 5 in the sliding groove 51. A guide sliding block 54 is movably connected to the guide sliding rod 52. The guide sliding block 54 is slidably connected in the sliding groove 51. A spring 53 is sleeved on the guide sliding rod 52, and the spring 53 is connected between the lower side of the guide sliding block 54 and the bottom of the sliding groove 51.
[0041] As an optimized technical solution of the present utility model, during the rotation of the gripping push rod 5, the auxiliary rod 6 will be driven to rotate. Due to the elastic force of the spring 53, the auxiliary rod 6 will resist the rightward rotation of the gripping push rod 5. Combined with the fitting state of the device with the concrete surface, the force applied to the lower side of the arc-shaped housing 1 by the gripping push rod 5 can be transmitted to the upper side of the arc-shaped housing 1 through the auxiliary rod 6, so as to ensure that the device is always in a fitting state with the concrete surface whether it moves to a high place or a low place during the entire leveling process.
[0042] Specific implementation cases:
[0043] First, when controlling the flatness of the sprayed concrete between the piles of the station, the device can be placed on the surface of the sprayed concrete, and the rolling columns 4 are abutted against the concrete.
[0044] Next, start the motor 34. The motor 34 drives the first rotating shaft 31 to rotate, and then drives the leveling roller 32 to rotate. The leveling roller 32 drives the scraping plate 33 to rotate, so as to level the protruding parts or fill the sunken parts of the sprayed concrete through the scraping plate 33. Then, the gripping push rod 5 can be pushed and pulled to move on the concrete surface, and the overall flatness of the surface of the sprayed concrete can be controlled through the scraping plate 33 during the movement.
[0045] Finally, during the process of controlling the flatness by moving the device, the excess concrete can be scraped off, causing it to fall to the bottom of the arc-shaped housing 1, and the concrete can be collected from the collection port 11 at its bottom. By connecting a collection pipe to the collection port 11, the excess concrete can be collected and processed uniformly, thus avoiding a large amount of concrete falling on the ground during the flatness control process and reducing the work burden of the construction personnel.
[0046] The specific implementation manners described above further elaborate on the purpose, technical solutions, and beneficial effects of the present utility model. It should be understood that the above are only the specific implementation manners of the present utility model and are not used to limit the protection scope of the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
