Description

Technical Field

[0001] This utility model relates to the field of track engineering construction equipment technology, specifically to an adjustable steel column pre-embedded part positioning tool. Background Technology

[0002] In the field of railway engineering construction, the precise installation of steel column embedded parts is a crucial step in ensuring the stability of the subsequent superstructure. Currently, the traditional method commonly used on construction sites relies on manual measurement and layout. After determining the approximate position of the embedded parts on the reinforcing cage or formwork, they are then fixed by temporary welding or binding. This method reveals many drawbacks throughout the construction process: First, the adjustment of the position and orientation of the embedded parts depends entirely on the experience of the operators and is done manually, which is cumbersome and inefficient, making it difficult to achieve rapid and accurate positioning. Second, due to the lack of dedicated positioning fixtures, the embedded parts are easily disturbed by external forces such as vibration during the concrete pouring stage, resulting in displacement or tilting, directly affecting the final installation quality. In addition, the existing method lacks an integrated movement and clamping system, making it impossible to quickly transfer and repeatedly position the fixtures between multiple embedded points along the track, thus restricting overall construction efficiency. Therefore, there is an urgent need for a dedicated positioning device that integrates movement, driving, and stable clamping to overcome the shortcomings of existing technologies. Utility Model Content

[0003] The purpose of this utility model is to provide an adjustable positioning fixture for embedded steel columns to solve the problems of cumbersome operation, low positioning efficiency, and easy misalignment.

[0004] To achieve the above objectives, the present invention provides an adjustable steel column embedded part positioning fixture using the following technical solution:

[0005] An adjustable positioning fixture for embedded steel column components includes: A fixed frame with a cylinder fixedly connected to its top surface, the output end of which slides along a first direction; A slide rail is fixedly mounted on the top surface of the mounting frame. The length direction of the slide rail extends along a second direction, which is perpendicular to the first direction. A fixed block is fixedly connected to the output end of the cylinder and is equipped with two symmetrically arranged guide rods. Each guide rod is rotatably connected to a slider, and the slider is slidably connected to the slide rail. The clamping assembly includes two opposing clamping plates and a transmission linkage group connecting the slider and the clamping plates; The two sliders are configured to move synchronously toward or away from each other under the drive of the cylinder, thereby driving the two clamps to move closer to or apart from each other via the transmission linkage.

[0006] As an optimization of the positioning fixture for adjustable steel column embedded parts, the transmission linkage assembly includes: An arc-shaped fixing rod is fixedly connected to the slider; The first adjusting rod, the middle part of which is rotatably connected to the end of the arc-shaped fixing rod; The second adjusting rod is rotatably connected at both ends to one end of the first adjusting rod and the fixed frame, respectively. The third adjusting rod is rotatably connected at both ends to the other end of the first adjusting rod and the clamping plate, respectively.

[0007] As an optimization of the positioning fixture for adjustable steel column embedded parts, the side wall of the fixing frame is fitted with a positioning pin, and the end of the positioning pin passes through the fixing frame and abuts against the outer side wall of the clamping plate.

[0008] As an optimization of the positioning fixture for adjustable steel column embedded parts, the bottom two sides of the fixing frame are provided with rollers.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) By using cylinder drive and mechanical linkage, the pre-embedded parts are automatically clamped and released, reducing the tedious steps of manual measurement and fixing, and significantly improving construction efficiency; (2) A multi-link transmission mechanism is adopted to ensure that the clamping force is evenly distributed. Combined with positioning pins for further reinforcement, it effectively prevents the embedded parts from shifting or tilting during the concrete pouring process, thus ensuring the installation accuracy.

[0013] To make the technical solution and advantages of this utility model clearer, the present utility model and its beneficial effects will be described in further detail below with reference to specific embodiments and accompanying drawings. However, the embodiments of this utility model are not limited thereto.

[0014] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0015] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail below.

[0017] This application provides an adjustable positioning fixture for embedded steel column parts, which adopts the following technical solution: Reference Figure 1 , Figure 2 and Figure 3The positioning fixture includes a fixed frame, a slide rail, a fixed block, guide rods, a slider, and a clamping assembly. The fixed frame serves as the support structure for the entire fixture. Rollers are installed on both sides of the bottom of the fixed frame, facilitating flexible movement of the fixture on the construction track or ground for rapid positioning and transfer. A cylinder is fixedly mounted on the top surface of the fixed frame. The output end of the cylinder reciprocates linearly along a first direction (X-direction), and the length of the fixed frame extends along the X-direction. The slide rail is fixedly mounted on the top surface of the fixed frame, extending along a second direction (Y-direction), which is perpendicular to the first direction. The fixed block is a flat cuboid, fastened to the output end of the cylinder with screws. Two guide rods are symmetrically arranged on the fixed block. One end of each guide rod is rotatably mounted on the fixed block, and the other end is rotatably mounted with a slider, which is slidably connected to the slide rail. When the cylinder operates, the extension and retraction of the cylinder's output end drives the fixed block to move along the X-direction. Because the guide rod is rotatably connected to the fixed block and the slider, the movement of the fixed block forces the guide rod to swing, thereby causing the two sliders to move synchronously towards or away from each other on the slide rail. Specifically, when the cylinder output end extends, pushing the fixed block closer to the slide rail, the two guide rods swing outward, causing the two sliders to move away from each other; when the cylinder output end retracts, pulling the fixed block away from the slide rail, the two guide rods swing inward, causing the two sliders to move towards each other, thus achieving clamping or releasing of the embedded part, thereby achieving rapid positioning.

[0018] Furthermore, referring to Figure 1 and Figure 3 The clamping assembly includes two opposing clamping units. Each clamping unit includes a clamping plate and a transmission linkage assembly positioned between the slider and the clamping plate. Specifically, the transmission linkage assembly includes an arc-shaped fixed rod, a first adjusting rod, a second adjusting rod, and a third adjusting rod. The arc-shaped fixed rod is fixedly connected to the bottom of the slider and moves synchronously along the Y direction with the slider. The middle part of the first adjusting rod is rotatably connected to the end of the arc-shaped fixed rod via a bearing, allowing the first adjusting rod to rotate around the connection point. One end of the second adjusting rod is rotatably connected to one end of the first adjusting rod via a bearing, and the other end is rotatably connected to the fixed frame via a bearing, providing auxiliary support and enhancing structural stability. One end of the third adjusting rod is rotatably connected to the other end of the first adjusting rod via a bearing, and the other end is rotatably connected to the side wall of the clamping plate via a bearing.

[0019] When the slider moves along the Y direction, it drives the arc-shaped fixed rod to move, thereby driving the first adjusting rod to rotate around its connection point with the arc-shaped fixed rod. The rotation of the first adjusting rod is ultimately converted into the closing or opening action of the clamping plate through the linkage of the second and third adjusting rods. Specifically, when the two sliders move towards each other, the two clamping plates move closer to each other through the transmission linkage group, clamping the embedded part; when the two sliders move away from each other, the two clamping plates separate from each other, releasing the embedded part.

[0020] In the preferred embodiment of this application, reference is made to Figure 1 and Figure 2 To further improve clamping stability, locating pins are inserted into the side walls of the fixing frame. The end of the locating pin passes through the fixing frame and abuts against the outer wall of the clamping plate. When the two clamping plates clamp multiple embedded parts, the locating pins are pressed against the outer side of the clamping plates to ensure that the clamping force is evenly distributed, prevent loosening and falling off, and thus enhance the anti-interference ability.

[0021] The application process and implementation principle of this embodiment are as follows: First, the fixture is moved to the target installation position by the rollers at the bottom of the fixed frame. The cylinder is activated, causing its output end to push the fixed block. Through the transmission of the guide rod and slider, the transmission linkage group moves, causing the two clamping plates to tightly fit and clamp the sides of multiple embedded parts. This achieves unified positioning of multiple embedded parts, thereby improving positioning efficiency and accuracy. During concrete pouring, the fixture maintains the stable position of the embedded parts, preventing misalignment caused by vibration. After installation, the cylinder retracts, the clamping plates open, and the fixture can be moved to the next work station for reuse. This embodiment, through the combination of cylinder drive and multi-link transmission, achieves rapid, accurate positioning and stable clamping of embedded parts, significantly improving construction efficiency and installation quality. Furthermore, the fixture has a compact structure and is flexible in movement, making it suitable for various construction scenarios in track engineering.

[0022] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
