Description

Technical Field

[0001] This utility model relates to the field of column clamping and positioning technology, specifically a column clamping and positioning device. Background Technology

[0002] In fields such as building construction, machinery manufacturing, and equipment installation, columns serve as load-bearing or supporting components. During installation, they require clamping and positioning devices to ensure verticality and stability, thereby guaranteeing subsequent assembly accuracy and overall structural safety. Currently, commonly used column clamping and positioning devices in the industry employ a combination of bolts and connecting hoops for fixing: first, the connecting hoops are fitted onto the outside of the column, and then multiple sets of bolts are passed through the lugs of the connecting hoops and gradually tightened, utilizing the axial force of the bolts to cause the connecting hoops to contract and clamp the column.

[0003] However, this fixing method has certain drawbacks: Firstly, during installation, each bolt hole must be aligned and each bolt tightened individually, which is a cumbersome process, especially for large columns or high-altitude operations, which is time-consuming, labor-intensive, and inefficient. Secondly, during disassembly, the bolts need to be loosened one by one in reverse. If the bolts become rusted or stuck after long-term use, it will further increase the difficulty of disassembly and prolong the equipment maintenance or component replacement cycle. Third, when it is necessary to clamp columns of different diameters, the corresponding connecting clamps need to be replaced and the installation position of the bolts needs to be readjusted. The poor adaptability makes it impossible to achieve quick switching, which increases the equipment investment cost and inventory pressure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a column clamping and positioning device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A column clamping and positioning device is provided, with symmetrical arrangement on the left and right sides. One side of the device includes: a base, a fixed bending plate fixedly arranged at the top center of the base, a hydraulic cylinder fixedly arranged on the fixed bending plate, guide rails fixedly arranged on the front and rear sides of the top of the base by bolts, a movable plate arranged on the guide rails, a fixing component arranged at the top of the telescopic rod of the hydraulic cylinder, the fixing component being fixedly connected to the top of the movable plate by bolts, and clamping plates symmetrically arranged on the front and rear sides of the movable plate away from the hydraulic cylinder by bolts, with a detachable positioning plate arranged between the clamping plates on both sides. The hydraulic cylinder is used to start and drive the moving plate to move left and right along the guide rail. The inner side of the clamping plate is provided with a groove for embedding the detachable positioning plate. The detachable positioning plate is provided with multiple sets of semi-circular grooves on the side away from the hydraulic cylinder. The semi-circular grooves are combined with the semi-circular grooves on the other side of the device to clamp the column.

[0006] Preferably, guide rail recesses are fixedly provided on the front and rear sides of the bottom of the movable plate, and the guide rail recesses are used to engage with the guide rail.

[0007] Preferably, the clamping plate at the connection between the clamping plate and the movable plate is provided with a long through hole. The long through hole is used to adjust the width between the front and rear clamping plates by bolts, so as to accommodate detachable positioning plates of different sizes.

[0008] Preferably, there are multiple detachable positioning plates, and the semi-circular grooves on each detachable positioning plate have different diameters, which are used to accommodate columns of different sizes.

[0009] Compared with the prior art, the present invention provides a column clamping and positioning device, which has the following advantages: The clamping plate is connected to the movable plate by bolts, and a long through hole is provided on the clamping plate, allowing the spacing between the front and rear clamping plates to be adjusted along the length of the through hole. This design allows the clamping plate to flexibly adapt to the size of the detachable positioning plate, and it is compatible with positioning plates of different thicknesses without replacing the clamping plate itself. This avoids the problem of traditional devices requiring the replacement of the entire unit due to the fixed size of the clamping components, reducing component replacement costs, and also providing a structural basis for the rapid installation of the positioning plate.

[0010] The detachable positioning plate is designed as multiple independent components, with semi-circular grooves of different diameters on each positioning plate. When it is necessary to clamp columns of different sizes, there is no need to adjust the main structure of the device. Only the positioning plate with the corresponding semi-circular groove diameter needs to be replaced. The operation is simple and quick, shortening the switching time for clamping columns of different specifications and solving the compatibility problem of traditional devices that require the replacement of the entire set of connecting clamps.

[0011] Meanwhile, the positioning plate is installed by embedding it into the clamping plate groove, without the need for additional fasteners such as bolts. During installation, the positioning plate can be directly placed into the clamping plate groove, and during disassembly, it can be directly removed. This eliminates the cumbersome process of traditional devices that rely on bolts for installation and disassembly. Even in confined spaces or high-altitude operation scenarios, the operation can be easily completed, improving the efficiency of clamping and positioning and reducing the intensity of manual operation.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Reference Figs. 1-3 As shown, a column clamping and positioning device in this embodiment includes a base 1, which serves as the supporting foundation of the device and provides stable support for the overall structure. A fixing plate 101 is fixedly installed at the top center of the base 1. The structural design of the fixing plate 101 is adapted to the installation angle of the hydraulic cylinder 3, and its surface is fixedly connected to the hydraulic cylinder 3 by bolts to ensure that the hydraulic cylinder 3 does not shift during operation.

[0016] Guide rails 102 are bolted to the front and rear sides of the top of the base 1. The parallelism of the guide rails 102 is precisely calibrated to provide a stable path for the movement of the movable plate 201. The movable plate 201 is mounted on the guide rails 102. Guide rail recesses 2011 are fixed to the front and rear sides of the bottom of the movable plate 201. The guide rail recesses 2011 and the guide rails 102 are embedded in each other. This kind of engagement can limit the lateral displacement of the movable plate 201 and ensure that the movable plate 201 moves linearly along the guide rails 102.

[0017] A fixing member 301 is provided at the top of the telescopic rod of the hydraulic cylinder 3. The fixing member 301 is fixedly connected to the top of the movable plate 201 by bolts. When the hydraulic cylinder 3 is started, the extension and retraction of the telescopic rod can directly drive the movable plate 201 to move left and right along the guide rail 102, realizing the power transmission of clamping or releasing action. On the side of the movable plate 201 away from the hydraulic cylinder 3, clamping plates 202 are symmetrically arranged on the front and rear sides by bolts. A space is reserved between the two clamping plates 202 to accommodate the detachable positioning plate 204. The inner side of the clamping plate 202 is provided with a groove. The size of the groove is adapted to the thickness of the detachable positioning plate 204 for embedding the detachable positioning plate 204.

[0018] The detachable positioning plate 204 has multiple sets of semi-circular grooves on the side away from the hydraulic cylinder 3. When the left and right sides of the device move symmetrically, the semi-circular grooves of the detachable positioning plates 204 on both sides can combine to form a complete circular clamping space for stable clamping of the column. At the same time, the clamping plate 202 at the connection between the clamping plate 202 and the moving plate 201 is provided with an elongated through hole 203. By adjusting the position of the bolt in the elongated through hole 203, the width between the front and rear clamping plates 202 can be changed, thereby accommodating detachable positioning plates 204 of different thicknesses. There are multiple detachable positioning plates 204, and the semi-circular grooves on each detachable positioning plate 204 have different diameters, which can adapt to the clamping requirements of columns of different sizes.

[0019] In some examples, the side of the movable plate 201 is provided with position indicator scale lines. The scale lines are based on one end of the guide rail 102. The operator can align the scale lines of the two movable plates 201 to ensure that the moving distance of the left and right movable plates is consistent, so that the semi-circular grooves of the two positioning plates are precisely aligned, further improving the coaxiality of the column clamping.

[0020] The working principle of this utility model is as follows: Before using the column clamping and positioning device, preliminary installation and adaptation preparations must be completed. First, depending on the installation scenario of the column, place the base 1 on both sides of the device stably, using the rigid structure of the base 1 to ensure overall stability. Confirm the connection status between the fixed bending plate 101 at the top center of the base 1 and the hydraulic cylinder 3. The two are fixed with bolts, and the tightness of the bolts must be checked to prevent displacement of the hydraulic cylinder 3 during operation. At the same time, confirm that the guide rails 102 on the front and rear sides of the top of the base 1 are fixed in place with bolts, and that the parallelism of the guide rails 102 meets the requirements. The guide rail recess 2011 at the bottom of the moving plate 201 is embedded with the guide rail 102 to ensure that the moving plate 201 can slide smoothly along the guide rail 102 without jamming or offset.

[0021] Next, based on the diameter of the column to be clamped, select a detachable positioning plate 204 with a corresponding semi-circular groove diameter. If the thickness of the positioning plate 204 does not match the spacing between the current clamping plates 202, this can be achieved by adjusting the position of the bolts connecting the clamping plates 202 and the moving plate 201: Since the clamping plates 202 have elongated through holes 203, after loosening the bolts, move the clamping plates 202 along the length of the elongated through holes 203 until the groove spacing of the two clamping plates 202 matches the thickness of the positioning plate 204, and then retighten the bolts to fix the clamping plates 202. Subsequently, the detachable positioning plate 204 is directly embedded into the grooves of the two clamping plates 202 without the need for additional fasteners. The precise fit between the grooves and the positioning plate 204 prevents the positioning plate 204 from loosening laterally during clamping, laying the foundation for stable clamping in the future.

[0022] After the adaptation is completed, the hydraulic cylinder 3 is activated. The telescopic rod of the hydraulic cylinder 3 will extend and retract axially, driving the moving plate 201 to move linearly along the guide rail 102 through the top fixing part 301. The embedded cooperation between the guide rail recess 2011 and the guide rail 102 can limit the vertical displacement of the moving plate 201, ensuring the stability of the movement trajectory. Since the device is symmetrically arranged on the left and right sides, the hydraulic cylinders 3 on both sides act synchronously, driving the moving plates 201, clamping plates 202 and detachable positioning plates 204 on both sides to move closer to each other. When the semi-circular grooves of the positioning plates 204 on both sides are fully engaged, they will form a complete circular clamping space that matches the diameter of the column. As the hydraulic cylinder 3 continues to output pressure, the positioning plates 204 will generate a uniform clamping force on the column, achieving stable positioning of the column and avoiding the column displacement problem caused by uneven force in traditional bolt connections.

[0023] If it is necessary to switch to clamping columns of different sizes, there is no need to adjust the main structure of the device: first, control the hydraulic cylinder 3 to retract, so that the positioning plates 204 on both sides are separated from the column, directly take out the original positioning plate 204 from the groove of the clamping plate 202, replace it with a new positioning plate 204 of the corresponding size, and then start the hydraulic cylinder 3 to complete the re-clamping, which greatly shortens the size switching time.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
