Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, and in particular to a self-lifting installation platform for bridge column clamps. Background Technology

[0002] Bridge pier clamps are devices used to secure and support bridge piers. They are typically made of metal and possess strong gripping and load-bearing capabilities. The clamps tightly wrap around the pier and are secured with bolts or other connectors to ensure the pier's stability and safety. The design of the clamps can be adjusted to suit the shape and size of different bridges, accommodating various pier requirements. Using bridge pier clamps effectively prevents piers from tilting, sinking, or moving, ensuring the structural stability and safe operation of the bridge.

[0003] While bridge pier clamps play a significant role in fixing and supporting piers, they also have some potential drawbacks: 1. Because the clamps need to tightly wrap around the pier for fixation, the installation and disassembly process can be cumbersome and time-consuming, especially when maintaining or replacing existing bridges, which may require additional tools and procedures; 2. Once the clamps are installed, inspecting and maintaining the piers can become more difficult, requiring specialized equipment and techniques to release the clamps for necessary repairs and maintenance; 3. The clamps firmly bind the piers together, restricting their free movement. This may affect the stress distribution and deformation capacity of the piers, leading to uneven structural stress or reduced load-bearing capacity. Therefore, this invention addresses the shortcomings of the aforementioned technologies. Summary of the Invention

[0004] Based on the aforementioned technical problems, this invention proposes a self-lifting installation platform for bridge column clamps.

[0005] The present invention proposes a bridge column clamp self-lifting installation platform, comprising two columns for operation on their outer surfaces, with support sleeves movably sleeved at the upper and lower ends of the outer surfaces of the two columns, a clamp platform fixedly sleeved on the outer surface of the support sleeves, a clamping mechanism provided on the inner surface of the support sleeves, a driving mechanism provided on the upper surface of the clamp platform, and a continuous lifting mechanism provided on the outer side of the clamp platform.

[0006] The clamping mechanism moves up and down on the outer surface of the column and automatically clamps the column.

[0007] The driving mechanism drives the clamping mechanism on the upper surface of the clamping platform to clamp the outer surface of the column.

[0008] The continuous lifting mechanism alternately lifts one side of the column and pulls the clamping mechanism and the driving mechanism to rise synchronously.

[0009] Preferably, the front and rear side surfaces of the support sleeve are fixedly connected to extended support lugs, the upper surface of the support lugs is fixedly connected to a sand cylinder, the upper surface of the sand cylinder is fixedly connected to a reinforcing chord, the upper surface of the upper end of the reinforcing chord is fixedly connected to a Bailey plate, the side surface of the Bailey plate is equipped with scissor braces, and the upper surface of the Bailey plate is fixedly connected to a square timber.

[0010] Through the above technical solution, in order to build bridge piers, an installation platform is built on the outer surface of the already formed column. In order to support the installation platform, Bailey panels, scissor braces, and square timbers are set on the outer surface of the clamping mechanism through reinforcing chords.

[0011] Preferably, the clamping mechanism includes a threaded sleeve that is movably fitted onto the outer surface of the column, the lower surface of the threaded sleeve being fixedly connected to the upper surface of the support sleeve, the interior of the support sleeve being a T-shaped sleeve, and the inner wall of the support sleeve having a movable ring that slides and extends, the inner surface of the movable ring being slidably fitted onto the outer surface of the column.

[0012] Through the above technical solution, in order to fix the clamping platform on the outer surface of the column, thereby enabling the placement of the installation platform and ensuring the safe operation of the workers, the clamping platform and the support sleeve are integrated and raised to a suitable position on the outer surface of the column. Then, by controlling the height adjustment of the movable ring inside the support sleeve, the column can be clamped tightly.

[0013] Preferably, the clamping mechanism further includes an elastic clamping cylinder fixedly connected to the upper surface of the movable ring. The elastic clamping cylinder consists of a bottom ring and elastic pieces arranged in a ring array on its upper surface. The inner surface of the elastic clamping cylinder is in sliding contact with the outer surface of the column.

[0014] Through the above technical solution, the upper end of the elastic clamp extends to the outer side of the upper end of the threaded sleeve and is tapered. In order to achieve the clamping of the column after the height of the movable ring is adjusted, the elastic clamp moves downward with the movable ring. The upper end of the elastic clamp gradually contracts as it moves downward, thereby clamping the outer surface of the column. In order to improve the friction of the elastic clamp, the inner surface of the elastic sheet that constitutes the structure is made of rubber material, thereby preventing the elastic clamp from slipping.

[0015] Preferably, the clamping mechanism further includes buffer telescopic rods that are fixedly connected to the lower surface of the movable ring in a ring array, the outer surface of the buffer telescopic rods is fixedly sleeved with buffer springs, and the lower surface of the buffer telescopic rods is fixedly connected to the inner bottom wall of the support sleeve.

[0016] Through the above technical solution, in order to buffer and limit the movement of the elastic clamp, increase its clamping force, and connect it to the support sleeve, a buffer telescopic rod is set on the lower surface of the movable ring, so that it can telescopically support the movement of the elastic clamp.

[0017] Preferably, the driving mechanism includes a concave tube sleeve threaded onto the outer surface of the threaded sleeve, and the inner top wall of the concave tube sleeve slides in contact with the upper surface of the elastic clamp.

[0018] Through the above technical solution, in order to control the elastic clamp to automatically descend and retract to clamp the column, the concave tube sleeve rotates at a constant speed on the outer surface of the threaded sleeve and moves linearly downward, thereby squeezing the elastic clamp to move downward and retract to achieve clamping. Furthermore, the outer surfaces of the concave tube sleeve and the threaded sleeve are threadedly connected, thereby preventing the elastic clamp from loosening.

[0019] Preferably, the driving mechanism further includes a driving gear movably sleeved on the outer surface of the concave tube sleeve. The lower surface of the driving gear is rotatably mounted on the upper surface of the support sleeve via a bearing. Key rods are symmetrically distributed and fixedly connected to the inner sidewall of the driving gear. A keyway is provided on the outer surface of the concave tube sleeve to slide and engage with the corresponding outer surface of the key rod. A reduction motor is fixedly connected to the upper surface of the opposite end of each of the left and right clamping platforms. A drive gear is fixedly connected to the outer surface of the output shaft of the reduction motor via a coupling. The outer surface of the drive gear meshes with the outer surface of the driving gear.

[0020] With the above technical solution, in order to drive the concave sleeve to rotate and move downward to achieve the locking of the elastic clamp, the reduction motor on the upper surface of the clamp platform is activated to control the rotation of the drive gear. The drive gear is supported and connected to the upper surface of the support sleeve through the bearing, thereby causing the drive gear to rotate. With the cooperation of the key rod and the keyway, the drive gear controls the concave sleeve to rotate and move downward, thereby squeezing the elastic clamp to move downward and contract inside the support sleeve.

[0021] Preferably, the continuous lifting mechanism includes a concave plate vertically disposed on one side of the column, a connecting block fixedly connected to the lower surface of the concave plate, one side surface of the connecting block fixedly connected to one side surface of the lower clamping platform, a T-shaped plate slidably engaging the concave surface of the concave plate, and one side surface of the upper end of the T-shaped plate fixedly connected to one side surface of the upper clamping platform via another connecting block.

[0022] The above technical solution aims to avoid increasing the workload of bridge construction by repeatedly disassembling and installing the installation platform. An automatic telescopic clamping mechanism is used to clamp the columns, and a concave plate assists the T-shaped plate in rising. This causes the T-shaped plate to lift the upper clamping platform a certain distance, and the concave plate, in turn, assists the lower clamping platform in rising the same distance, thus achieving continuous lifting of the installation platform.

[0023] Preferably, the continuous lifting mechanism further includes an external toothed rod fixedly connected to the inner surface of one side of the concave plate, a guide rod and a guide frame respectively movably sleeved on the outer surfaces of the upper and lower ends of the column, a first drive motor fixedly installed at one end of the guide rod, a circular groove penetrating through one side surface of the lower end of the T-shaped plate, a first track gear rotatably connected to the inner wall of the circular groove via a rotating shaft, the outer surface of the output shaft of the first drive motor being fixedly connected to the rotating shaft surface of the first track gear via a coupling, and the outer surface of the first track gear meshing with the tooth surface of the external toothed rod.

[0024] Through the above technical solution, in order to make the upper loose clamp platform drive the installation platform on the Bailey plate to adjust its height, so that the T-shaped plates on one side of the two columns rise synchronously, and pull the clamp platform up through the connecting block, in order to control the rise of the T-shaped plate, the first drive motor drives the first track gear in the circular groove to rotate, so that the first track gear rotates and moves upward on the tooth surface of the outer gear rod, thereby realizing the sliding upward movement of the T-shaped plate on the inner surface of the concave plate.

[0025] Preferably, the continuous lifting mechanism further includes a movable groove extending from the upper surface of the T-shaped plate, an internal gear fixedly connected to one inner wall of the movable groove, the inner surface of the front end of the guide frame fixedly connected to the outer surface of the concave plate, a second drive motor fixedly connected to the front end surface of the guide frame, the output shaft of the second drive motor extending into the interior of the movable groove and fixedly connected to a second track gear via a coupling, the outer surface of the second track gear meshing with the tooth surface of the internal gear.

[0026] Through the above technical solution, in order to lift the lower clamping platform by the same distance so that the upper clamping platform can drive the installation platform to be continuously lifted, the T-shaped plate causes the second track gear to reverse due to the lifting of the internal gear rod. After the T-shaped plate is lifted, the second drive motor controls the second track gear in the movable slot to rotate forward, so that the second track gear rotates and moves upward at the lower end of the internal gear rod, thereby driving the connected guide frame to pull the concave plate upward.

[0027] Preferably, guide rollers are symmetrically distributed and fixedly connected to the inner wall of the circular end of the guide frame and the guide rod, and the outer surface of the guide rollers slides in contact with the outer surface of the column.

[0028] Through the above technical solution, in order to provide force support for the first drive motor and the second drive motor, the annular ends of the guide frame and the guide rod are movably connected to the column. In order to reduce the moving resistance of the guide frame and the guide rod, guide rollers are provided on the inner wall of their annular ends to achieve rolling upward movement on the outer surface of the column.

[0029] The beneficial effects of this invention are as follows:

[0030] 1. By setting up a clamping mechanism, the column can be quickly and automatically clamped, which facilitates the construction of the installation platform. During the adjustment process, the concave tube rotates at a constant speed on the outer surface of the threaded sleeve and moves linearly downward, which in turn squeezes the elastic clamp to move downward and contract to achieve clamping. The concave tube and the outer surface of the threaded sleeve are threadedly connected, which can prevent the elastic clamp from loosening. In order to improve the friction of the elastic clamp, the inner surface of the elastic plate that constitutes the structure is made of rubber material, which can prevent the elastic clamp from slipping. This facilitates the later inspection and maintenance of the column. Furthermore, the rubber material on the inner surface of the clamping mechanism can avoid affecting the stress distribution and deformation capacity of the column.

[0031] 2. By setting up a continuous lifting mechanism, the clamp platform used to build the installation platform can be continuously lifted. During the adjustment process, the concave plate assists the T-shaped plate to rise, so that the T-shaped plate drives the upper clamp platform to rise a certain distance. The T-shaped plate also assists the concave plate to rise, so that the concave plate drives the lower clamp platform to move upward by the same distance. This achieves continuous lifting of the installation platform and avoids the use of additional tools and operating steps, thereby improving the efficiency of bridge construction.

Detailed Implementation

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0044] Reference Figures 1-10 A bridge column clamp self-lifting installation platform includes two columns 1 that operate on their outer surfaces. Support sleeves 2 are movably sleeved at the upper and lower ends of the outer surfaces of the two columns 1. A clamp platform 3 is fixedly sleeved on the outer surface of the support sleeves 2. A clamping mechanism 4 is provided on the inner surface of the support sleeves 2. A driving mechanism 5 is provided on the upper surface of the clamp platform 3. A continuous lifting mechanism 6 is provided on the outer side of the clamp platform 3.

[0045] like Figure 1As shown, in order to build bridge piers, an installation platform is built on the outer surface of the pre-formed column 1. To support the installation platform, extended support lugs 21 are fixedly connected to the front and rear side surfaces of the support sleeve 2. A sand cylinder 22 is fixedly connected to the upper surface of the support lugs 21. A reinforcing chord 23 is fixedly connected to the upper surface of the sand cylinder 22. A Bailey plate 24 is fixedly connected to the upper surface of the upper reinforcing chord 23. A scissor brace 25 is installed on the side surface of the Bailey plate 24. A square timber 26 is fixedly connected to the upper surface of the Bailey plate 24.

[0046] like Figures 3-4 As shown, the clamping mechanism 4 moves up and down on the outer surface of the column 1 and automatically clamps the column 1.

[0047] To enable the clamping platform 3 to be fixedly installed on the outer surface of the column 1, thereby facilitating the placement of the installation platform and ensuring safe operation for workers, the clamping mechanism 4 includes a threaded sleeve 41 that is movably fitted onto the outer surface of the column 1. The lower surface of the threaded sleeve 41 is fixedly connected to the upper surface of the support sleeve 2. The support sleeve 2 has a T-shaped sleeve opening inside, and a movable ring 42 is slidably extended and retracted on the inner wall of the support sleeve 2. The inner surface of the movable ring 42 is slidably fitted onto the outer surface of the column 1. The clamping platform 3 is integrated with the support sleeve 2 and rises to a suitable position on the outer surface of the column 1. After controlling the height adjustment of the movable ring 42 within the support sleeve 2, the clamping of the column 1 can be achieved.

[0048] To enable the movable ring 42 to grip the column 1 after height adjustment, the gripping mechanism 4 also includes an elastic clamp 43 fixedly connected to the upper surface of the movable ring 42. The elastic clamp 43 consists of a bottom ring and elastic pieces arranged in a ring array on its upper surface. The inner surface of the elastic clamp 43 slides in contact with the outer surface of the column 1. The upper end of the elastic clamp 43 extends to the outer side of the upper end of the threaded sleeve 41 and is tapered. As the movable ring 42 moves downward, the upper end of the elastic clamp 43 gradually contracts as it moves downward, thereby gripping the outer surface of the column 1. To increase the friction of the elastic clamp 43, the inner surface of the elastic pieces constituting it is made of rubber, thereby preventing the elastic clamp 43 from slipping.

[0049] In order to buffer and limit the movement of the elastic clamp 43, increase its clamping force, and connect it to the support sleeve 2, the clamping mechanism 4 also includes buffer telescopic rods 44 that are fixedly connected to the lower surface of the movable ring 42 in a ring array. The outer surface of the buffer telescopic rod 44 is fixedly sleeved with a buffer spring 45, and the lower surface of the buffer telescopic rod 44 is fixedly connected to the inner bottom wall of the support sleeve 2. The buffer telescopic rod 44 extends and retracts to support the movement of the elastic clamp 43.

[0050] like Figures 2-3 and Figure 5As shown, the driving mechanism 5 drives the clamping mechanism 4 on the upper surface of the clamping platform 3 to clamp the outer surface of the column 1.

[0051] In order to control the elastic clamp 43 to automatically descend and retract to clamp the column 1, the drive mechanism 5 includes a concave tube sleeve 51 connected to the outer surface of the threaded sleeve 41. The inner top wall of the concave tube sleeve 51 slides in contact with the upper surface of the elastic clamp 43. The concave tube sleeve 51 rotates at a constant speed on the outer surface of the threaded sleeve 41 and moves linearly downward, thereby squeezing the elastic clamp 43 to move downward and retract to achieve clamping. Furthermore, the concave tube sleeve 51 is threadedly connected to the outer surface of the threaded sleeve 41, thereby preventing the elastic clamp 43 from loosening.

[0052] To drive the concave sleeve 51 to rotate and move downward to lock the elastic clamp 43, the drive mechanism 5 also includes a drive gear 52 movably sleeved on the outer surface of the concave sleeve 51. The lower surface of the drive gear 52 is rotatably mounted on the upper surface of the support sleeve 2 via a bearing. Key rods 53 are symmetrically distributed and fixedly connected to the inner sidewall of the drive gear 52. The outer surface of the concave sleeve 51 is provided with a keyway 54 that slides and engages with the corresponding key rod 53. A reduction motor 55 is fixedly connected to the upper surface of one of the opposite ends of the left and right clamping platforms 3. The output shaft of the reduction motor 55... The outer surface is fixedly connected to the drive gear 56 via a coupling. The outer surface of the drive gear 56 meshes with the outer surface of the drive gear 52. The drive gear 56 is rotated by the geared motor 55 on the upper surface of the clamping platform 3. The drive gear 52 is supported and connected to the upper surface of the support sleeve 2 via a bearing, which causes the drive gear 56 to drive the meshing drive gear 52 to rotate. The drive gear 52 controls the concave sleeve 51 to rotate and move downward under the cooperation of the key rod 53 and the keyway 54, which in turn squeezes the elastic clamp 43 to move downward and contract inside the support sleeve 2.

[0053] By setting up the clamping mechanism 4, the column 1 can be quickly and automatically clamped, which facilitates the construction of the installation platform. During the adjustment process, the concave tube sleeve 51 rotates at a constant speed on the outer surface of the threaded sleeve 41 and moves linearly downward, which in turn squeezes the elastic clamp 43 to move downward and contract to achieve clamping. The concave tube sleeve 51 is threadedly connected to the outer surface of the threaded sleeve 41, which can prevent the elastic clamp 43 from loosening. In order to improve the friction of the elastic clamp 43, the inner surface of the elastic sheet constituting the structure is made of rubber material, which can prevent the elastic clamp 43 from slipping, thus facilitating the later inspection and maintenance of the column 1. Furthermore, the rubber material on the inner surface of the clamping mechanism 4 can avoid affecting the stress distribution and deformation capacity of the column 1.

[0054] like Figures 6-10 As shown, the continuous lifting mechanism 6 alternately lifts one side of the column 1, and pulls the clamping mechanism 4 and the drive mechanism 5 to rise synchronously.

[0055] To avoid increasing the workload of bridge construction due to repeated disassembly and installation of the installation platform, the continuous lifting mechanism 6 includes a concave plate 61 vertically positioned on one side of the column 1. A connecting block 62 is fixedly connected to the lower surface of the concave plate 61, and one side surface of the connecting block 62 is fixedly connected to one side surface of the lower clamping platform 3. A T-shaped plate 63 is slidably engaged with the concave surface of the concave plate 61. One side surface of the upper end of the T-shaped plate 63 is fixedly connected to one side surface of the upper clamping platform 3 through another connecting block 62. The column 1 is clamped by an automatically telescopic clamping mechanism 4, and the concave plate 61 assists the T-shaped plate 63 in rising, causing the T-shaped plate to lift the upper clamping platform 3 upward a certain distance. The T-shaped plate 63 also assists the concave plate 61 in rising, causing the concave plate 61 to move the lower clamping platform 3 upward by the same distance, thereby achieving continuous lifting of the installation platform.

[0056] To enable the upper slack clamp platform 3 to drive the mounting platform on the Bailey plate 24 to adjust its height, and thus control the T-shaped plate 63 to rise, the continuous lifting mechanism 6 also includes an external gear rod 64 fixedly connected to the inner surface of one side of the concave plate 61. The upper and lower outer surfaces of the column 1 are respectively movably sleeved with guide rods 65 and guide frames 66. One end of the guide rod 65 is fixedly installed with a first drive motor 67. A circular groove 68 is opened through one side of the lower end of the T-shaped plate 63. The inner wall of the circular groove 68 is rotatably connected to a first track gear 69 through a rotating shaft. The outer surface of the output shaft of the first drive motor 67 is fixedly connected to the rotating shaft surface of the first track gear 69 through a coupling. The outer surface of the first track gear 69 meshes with the tooth surface of the external gear rod 64. The first drive motor 67 drives the first track gear 69 in the circular groove 68 to rotate, thereby causing the first track gear 69 to rotate and move upward on the tooth surface of the external gear rod 64, thus enabling the T-shaped plate 63 to slide and move upward on the inner surface of the concave plate 61.

[0057] To facilitate continuous lifting of the upper clamping platform 3 and the installation platform by lifting the lower clamping platform 3 by the same distance, the continuous lifting mechanism 6 also includes a movable groove 70 extending from the upper surface of the T-shaped plate 63. An internal gear 71 is fixedly connected to the inner wall of one side of the movable groove 70. The inner surface of the front end of the guide frame 66 is fixedly connected to the outer surface of the concave plate 61. A second drive motor 72 is fixedly connected to the front end of the guide frame 66. The output shaft of the second drive motor 72 extends into the interior of the movable groove 70 and is fixedly connected to a second track gear 73 via a coupling. The outer surface of the second track gear 73 meshes with the tooth surface of the internal gear 71. When the T-shaped plate 63 is lifted, the second track gear 73 reverses due to the lifting of the internal gear 71. After the T-shaped plate 63 is lifted, the second drive motor 72 controls the second track gear 73 in the movable groove 70 to rotate forward, thereby causing the second track gear 73 to rotate and move upward at the lower end of the internal gear 71, which in turn drives the connected guide frame 66 to pull the concave plate 61 upward.

[0058] In order to provide force support for the first drive motor 67 and the second drive motor 72, and in order to reduce the moving resistance of the guide frame 66 and the guide rod 65, guide rollers 74 are fixedly connected to the inner walls of the annular ends of the guide frame 66 and the guide rod 65 in a symmetrical manner, and the outer surface of the guide rollers 74 slides in contact with the outer surface of the column 1.

[0059] By setting up a continuous lifting mechanism 6, the clamp platform 3 used to build the installation platform can be continuously lifted. During the adjustment process, the concave plate 61 assists the T-shaped plate 63 to rise, so that the T-shaped plate drives the upper clamp platform 3 to rise a certain distance, and the T-shaped plate 63 assists the concave plate 61 to rise, so that the concave plate 61 drives the lower clamp platform 3 to move upward by the same distance, thereby realizing the continuous lifting of the installation platform. At the same time, it can avoid the use of additional tools and operating steps, thus improving the efficiency of bridge construction.

[0060] Working principle: such as Figures 1-10 As shown, in a specific embodiment of the present invention, the support sleeve 2, elastic clamp 43 and other structures are installed at intervals defined on the outer surface of the column 1, and the reinforcing chord 23, Bailey plate 24, scissor brace 25 and square timber 26 are installed on the outer surface of the upper clamp platform 3 to facilitate operation.

[0061] During operation, the elastic clamp 43 needs to hold the column 1 tightly. The reduction motor 55 on the upper surface of the clamp platform 3 is activated to control the rotation of the drive gear 56, which in turn drives the meshing drive gear 52 to rotate. The drive gear 52, with the cooperation of the key rod 53 and the keyway 54, controls the concave sleeve 51 to rotate and move downward, which in turn squeezes the elastic clamp 43 to move downward and contract inside the support sleeve 2. With the buffer spring 45 and the buffer limit rod, the elastic clamp 43 holds the column 1 tightly.

[0062] When the safety platform is lifted upwards a certain distance, the reduction motor 55 drives the drive gear 56 to rotate in the opposite direction, thereby causing the elastic clamp 43 to loosen its grip on the column 1. At this time, the first drive motor 67 drives the first track gear 69 in the circular groove 68 to rotate, thereby causing the first track gear 69 to rotate and move upwards on the tooth surface of the outer gear rod 64. This allows the T-shaped plate 63 to slide upwards on the inner surface of the concave plate 61. During the movement, the T-shaped plate 63 will be guided and supported by the guide rod 65, and the connecting block 62 will drive the upper clamp platform 3 and the mounting platform installed on its surface to rise to a certain distance.

[0063] Then, when the T-shaped plate 63 is lifted, the second track gear 73 reverses due to the lifting of the internal gear rod 71. After the T-shaped plate 63 is lifted, the second drive motor 72 controls the second track gear 73 in the movable groove 70 to rotate forward, so that the second track gear 73 rotates and moves upward at the lower end of the internal gear rod 71. This drives the connected guide frame 66 to pull the concave plate 61 upward. Finally, the concave plate 61 can be lifted by the same distance by pulling the lower end clamp platform 3 and the reinforcing chord rod 23 through another connecting block 62, thereby realizing the self-lifting of the clamp of the bridge column 1.

[0064] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
