Description

Technical Field

[0001] This application relates to the field of building construction technology, specifically to a platform structure for concentric and coaxial docking of steel pipe columns and tool columns. Background Technology

[0002] The reverse construction method for foundation pits is an unconventional platform structure in which steel pipe columns and tool columns are concentrically and coaxially connected. Its principle is to construct the underground structure of high-rise buildings layer by layer from top to bottom. That is, to construct continuous walls or closely spaced piles around the perimeter of the basement as the outer walls of the basement or the retaining structure of the foundation pit. At the same time, to construct intermediate support piles at relevant locations inside the building, thus forming a vertical load-bearing system for reverse construction. It is one of the commonly used construction methods in modern construction industry.

[0003] According to the concentric and coaxial docking platform structure for steel pipe columns and tool columns disclosed in Chinese Patent Publication No. CN215290120U, this patent, by setting up a support structure and driving element, allows the steel pipe column and tool column to be easily lifted and aligned, thus facilitating concentric and coaxial docking construction, which is very convenient. However, this patent still has some shortcomings in actual operation. In order for the steel pipe column and tool column to be raised and lowered normally, a certain distance needs to be maintained between them, so that docking can be carried out only when they are adjusted to be concentric and coaxial. The steel pipe column and tool column need to move on the arc-shaped part, and their own weight plus the friction between the steel pipe column and the arc-shaped part makes it inconvenient to move the steel pipe column and tool column, which requires a certain amount of time and labor. At the same time, although the single driving element can play a normal lifting and lowering role, it cannot accurately monitor the lifting and lowering height, thus indicating that the practicality of the existing concentric and coaxial docking platform structure for steel pipe columns and tool columns has certain room for improvement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a concentric and coaxial docking platform structure for steel pipe columns and tool columns, which has advantages such as facilitating easy docking operations and solves the problem that existing concentric and coaxial docking platform structures for steel pipe columns and tool columns are not convenient for docking operations after lifting and lowering.

[0005] To achieve the above objectives, this application provides the following technical solution: a concentric and coaxial docking platform structure for steel pipe columns and tool columns, including a base, the top of the base having four fixing slots, the inner side of the fixing slots being fixedly connected to fixing steel plates, a lifting block being slidably connected between opposite sides of two corresponding fixing steel plates, a docking component for smooth docking being installed on the top of the lifting block, and a lifting component for stable lifting being installed on the top of the base;

[0006] The docking assembly includes a docking groove formed on the top of the lifting block, with evenly distributed fixing rods fixedly connected between the left and right sides of the docking groove. An arc-shaped cylinder is rotatably connected to the outer side of the fixing rods. Anti-slip pads are fixedly connected to the top of the lifting block and the outer side of the arc-shaped cylinder. A rangefinder is fixedly installed at the bottom of the lifting block.

[0007] By adopting the above technical solution, the docking work can be easily carried out. After the two columns are raised to the same level, the docking work can be easily completed. This greatly reduces the friction and resistance during the docking movement, allowing the workers to carry out the construction more easily. At the same time, the equipment can help to accurately judge the current lifting height, making it easier for the workers to determine whether the two columns are in the same level, thus improving the convenience of the construction process.

[0008] Furthermore, each of the two opposing sides of the fixed steel plates is fixedly connected with an evenly distributed arched steel plate, and the bottom of the lifting block is fixedly connected with four evenly distributed support blocks.

[0009] By adopting the above technical solutions, the functions of limiting and supporting are respectively achieved.

[0010] Furthermore, the lifting assembly includes two drive mechanisms fixedly installed on the top of the base, a lifting groove is provided at the bottom of the lifting block, a connecting block is fixedly connected to the output shaft of the drive mechanism, two stabilizing grooves are provided on the opposite side of the two fixed steel plates, a positioning rod is fixedly connected between the top and bottom of the stabilizing groove, and four sliding blocks are fixedly connected to the outside of the lifting block.

[0012] Furthermore, the two fixed steel plates are symmetrically distributed from left to right, and the top of the lifting block is a downward-curved arc surface.

[0013] By adopting the above technical solution, the fixed steel plate can play a limiting role, and the curved surface can facilitate the placement of the column structure.

[0014] Furthermore, the docking groove is located at the center of the top of the corresponding lifting block, and the top of the arc-shaped cylinder is located at the top of the corresponding docking groove.

[0015] By adopting the above technical solution, the steel pipe column and tool column can be supported by correspondingly evenly distributed arc-shaped cylinders.

[0016] Furthermore, the left side of the arc-shaped cylinder has a circular hole through which the corresponding fixing rod passes, and the outer side of the arc-shaped cylinder bends toward the side closer to the corresponding fixing rod.

[0017] By adopting the above technical solution, the arc-shaped cylinder can rotate stably, and the steel pipe column and tool column can be moved by the arc shape.

[0018] Furthermore, the bottom of the arched steel plate is fixedly connected to the top of the base by bolts, and a buffer block is fixedly connected to the bottom of the support block.

[0019] By adopting the above technical solution, the arched steel plate can be stably installed and fixed, and the lifting block can be supported on the top of the base by the cooperation between the support block and the buffer block.

[0020] Furthermore, the top of the connecting block is fixedly connected to the top of the corresponding lifting groove, and the inner diameter of the lifting groove is larger than the diameter of the driving mechanism.

[0021] By adopting the above technical solution, the drive mechanism can drive the lifting block to adjust its height through the corresponding connecting block, and at the same time, the drive mechanism can move normally into the interior of the corresponding lifting slot.

[0022] Furthermore, the sliding block is located inside the corresponding stabilizing groove, and the bottom end of the positioning rod passes through the top of the corresponding sliding block.

[0023] By adopting the above technical solution, the sliding block can slide on the outside of the corresponding positioning rod, thereby allowing the lifting block to be stably adjusted in height by the cooperation of the four corresponding sliding blocks.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] This concentric and coaxial docking platform structure for steel pipe columns and tool columns facilitates easy docking work through the coordinated use of docking and lifting components at the top of the base. Once the columns are raised to a concentric and coaxial position, docking can be easily completed, significantly reducing friction and resistance during the docking process. This allows workers to perform construction more easily and accurately determine the current lifting height, helping them ascertain whether the two columns are concentric and coaxial, thus improving the convenience of the construction process and effectively enhancing the practicality of the concentric and coaxial docking platform structure for steel pipe columns and tool columns.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1-4 This application provides a technical solution: a concentric and coaxial docking platform structure for steel pipe columns and tool columns, including a base 1, four fixing slots 2 are provided on the top of the base 1, fixing steel plates 3 are fixedly connected to the inner side of the fixing slots 2, lifting blocks 4 are slidably connected between opposite sides of two corresponding fixing steel plates 3, docking components 500 for smooth docking are installed on the top of the lifting blocks 4, and lifting components 600 for stable lifting are installed on the top of the base 1.

[0033] The use of the docking component 500 and the lifting component 600 at the top of the base 1 facilitates easy docking work. After being raised to the concentric and coaxial position, docking can be easily completed, greatly reducing friction and resistance during the docking movement process. This allows workers to carry out construction more easily. At the same time, the equipment can help to accurately judge the current lifting height, making it easier for workers to determine whether the two columns are concentric and coaxial, thus improving the convenience of the construction process and effectively enhancing the practicality of the concentric and coaxial docking platform structure for steel pipe columns and tool columns.

[0034] It should be noted that each of the two fixed steel plates 3 has an evenly distributed arched steel plate 301 fixedly connected to the opposite side of each other. The bottom of the lifting block 4 has four evenly distributed support blocks 401 fixedly connected to it. The two fixed steel plates 3 are symmetrically distributed from left to right, so that the fixed steel plates 3 can play a limiting role. The top of the lifting block 4 is a downward curved surface, which is convenient for placing cylindrical objects.

[0035] In addition, the bottom of the arched steel plate 301 is fixedly connected to the top of the base 1 by bolts, so that the arched steel plate 301 can be stably installed and fixed. The bottom of the support block 401 is fixedly connected to a buffer block. The buffer block can be a rubber block or other structure with certain elastic properties and a relatively hard texture, so that the lifting block 4 can be supported on the top of the base 1 by the support block 401 and the buffer block.

[0036] In this embodiment, the docking component 500 is a structure used to facilitate the docking of steel pipe columns and tool columns.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, the docking assembly 500 includes a docking groove 501 formed on the top of the lifting block 4. Fixed rods 502 are fixedly connected between the left and right sides of the docking groove 501. An arc-shaped cylinder 503 is rotatably connected to the outside of the fixed rods 502. Anti-slip pads 504 are fixedly connected to the top of the lifting block 4 and the outside of the arc-shaped cylinder 503. The anti-slip pads 504 can be rubber pads or other structures with anti-slip function and wear resistance. A rangefinder 505 is fixedly installed at the bottom of the lifting block 4. The rangefinder 505 can be an infrared rangefinder, laser rangefinder, or other electronic equipment that can accurately measure height and distance.

[0038] It should be noted that the docking groove 501 is located at the center of the top of the corresponding lifting block 4, and the top of the arc-shaped cylinder 503 is located at the top of the corresponding docking groove 501, so that the steel pipe column and the tool column can be supported by the corresponding evenly distributed arc-shaped cylinders 503.

[0039] In addition, a circular hole is provided on the left side of the arc-shaped cylinder 503 for the corresponding fixed rod 502 to pass through. The outer side of the arc-shaped cylinder 503 bends towards the side close to the corresponding fixed rod 502, so that the arc-shaped cylinder 503 can rotate stably, and at the same time, the steel pipe column and the tool column can be moved by the arc shape.

[0040] In this embodiment, the lifting assembly 600 is a structure used to adjust the steel pipe column and the tool column to a concentric and coaxial position.

[0041] like Figure 1 and Figure 2As shown, the lifting assembly 600 includes two drive mechanisms 601 fixedly installed on the top of the base 1. The drive mechanism 601 can be a hydraulic rod, cylinder or other device with linear drive function. The bottom of the lifting block 4 is provided with a lifting groove 602. The output shaft of the drive mechanism 601 is fixedly connected to a connecting block 603. Two stabilizing grooves 604 are provided on opposite sides of the two fixed steel plates 3. A positioning rod 605 is fixedly connected between the top and bottom of the stabilizing groove 604. Four sliding blocks 606 are fixedly connected to the outside of the lifting block 4.

[0042] It should be noted that the top of the connecting block 603 is fixedly connected to the top of the corresponding lifting groove 602. The inner diameter of the lifting groove 602 is larger than the diameter of the drive mechanism 601, so that the drive mechanism 601 can drive the lifting block 4 to adjust its height through the corresponding connecting block 603, and at the same time, the drive mechanism 601 can move normally into the interior of the corresponding lifting groove 602.

[0043] In addition, the sliding block 606 is located inside the corresponding stabilizing groove 604, and the bottom end of the positioning rod 605 passes through the top of the corresponding sliding block 606, allowing the sliding block 606 to slide on the outside of the corresponding positioning rod 605. This allows the lifting block 4 to be stably adjusted in height by the cooperation of the four corresponding sliding blocks 606. All electronic components mentioned in this article are connected to the power supply and the main controller. The main controller can be a known control device such as a computer, and it is a publicly available power connection technology, so it will not be described in detail in this article.

[0044] The working principle of the above embodiments is as follows:

[0045] During the docking construction of the steel pipe column and tool column, the steel pipe column and tool column are hoisted and moved to the top of the two lifting blocks 4 respectively. The drive mechanism 601 is activated to drive the lifting blocks 4 to move upward. At the same time, under the sliding and limiting action between the four corresponding positioning rods 605 and sliding blocks 606 on both sides, the lifting blocks 4 can be smoothly and stably adjusted for lifting. With the help of the rangefinder 505, the distance between the bottom of the corresponding lifting block 4 and the top of the base 1 can be accurately determined. Thus, by using the different inner diameters of the steel pipe column and tool column, the two lifting blocks 4 can be raised to different heights, allowing the steel pipe column and tool column to move to a concentric and coaxial position, and then move closer to each other. With the cooperation between the anti-slip pad 504 and the arc-shaped cylinder 503, the steel pipe column and tool column can be smoothly docked and moved, thus facilitating the normal progress of the docking work.

[0046] Compared with existing technologies, this concentric and coaxial docking platform structure for steel pipe columns and tool columns facilitates easy docking work through the cooperation between the docking component 500 and the lifting component 600 at the top of the base 1. After being raised to the concentric and coaxial position, docking can be easily completed, greatly reducing friction and resistance during the docking movement process. This allows workers to carry out construction more easily. At the same time, the equipment can help to accurately judge the current lifting height, making it easier for workers to determine whether the two columns are concentric and coaxial, thus improving the convenience of the construction process. This effectively enhances the practicality of the concentric and coaxial docking platform structure for steel pipe columns and tool columns and solves the shortcomings of existing concentric and coaxial docking platform structures for steel pipe columns and tool columns that are not convenient for docking work after lifting.
