Description

Technical Field

[0001] This invention relates to the field of bridge construction facilities technology, and specifically discloses a clamping device and construction method for bridge cap beam construction. Background Technology

[0002] As a crucial structural component of bridges, the cap beam is a horizontal beam installed atop the piers to support, distribute, and transfer the loads of the superstructure. Before constructing the bridge cap beam, scaffolding needs to be erected around the piers to facilitate cast-in-place casting. During construction, clamps are fitted over the piers, and scaffolding is then erected on top of the clamps. This not only reduces the difficulty of formwork construction but also fully utilizes the existing structural load-bearing capacity, saving on engineering costs.

[0003] Existing clamping devices rely on the friction between the clamp and the pier to bear the construction weight of the cap beam. The friction between the pier and the clamp is difficult to determine accurately and mainly depends on empirical data, which poses parameter risks. At the same time, the cap beam clamping device itself is heavy, and the clamp is prone to slipping when the cap beam is poured with concrete, affecting the construction of the cap beam. Existing clamps are usually fixed with bolts, and when working at height, construction workers need to be suspended at the clamp to tighten it, which is slow. Construction workers are suspended for a long time, which poses safety hazards. In addition, the clamp is generally divided into two half rings, which pose a safety hazard of slipping instantly when disassembled. Summary of the Invention

[0004] The purpose of this invention is to provide a clamping device for the construction of cap beams, so as to solve the problems mentioned in the background art.

[0015] Secondly, this application provides a construction method for a clamping device for cap beam construction, which includes the following steps:

[0016] S1: First, adjust the position of the four hydraulic cylinders so that the four support blocks are concentric with clamping block one, clamping block two and two clamping blocks three respectively, and the hydraulic cylinders are tilted between the support blocks and each clamping block;

[0017] S2: According to the construction requirements, select and start clamping block one and clamping block three, adjacent clamping block two and clamping block three, and at least one rotating component between two adjacent clamping blocks three. Power on the electromagnetic block fixed above the support shaft. The electromagnetic block above attracts the fork to slide upward and drives the spline sleeve to slide upward and mesh with the drive gear. Operate the motor to open clamping block one and clamping block two or clamping block one, clamping block two and any clamping block three. Place the clamping device for cap beam construction at a suitable height on the pier column.

[0018] S3: Reverse start of the rotating component in S1, so that clamping block one, clamping block two and two clamping blocks three close into a ring, so that protruding plate one and protruding plate two are aligned. When closed, the support sleeve limits clamping block one.

[0019] S4: Insert the pin into the rectangular through slot and rotate it 90 degrees so that the fixing head engages with the rectangular blind slot and is fixed by magnetic adsorption using the electromagnetic plate;

[0020] S5: Adjust the position of the four hydraulic cylinders so that they are directly opposite the center of the pier column, extend the piston rod, and make the support block press against the pier column;

[0021] S6: Operate the rotating components below clamping block one and clamping block two to energize the electromagnetic block fixed below the spline sleeve. The electromagnetic block below attracts the shift fork to slide downward, separating the spline sleeve and the drive gear, thus protecting the motor from misoperation during clamping operation.

[0022] S7: After installation, a formwork support can be erected above support plate one, support plate two, or support plate three for the construction of the cap beam.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention provides a clamping device for cap beam construction. The clamping component can be rotated and opened in multiple positions. Each clamping block can be selectively driven according to the diameter of the pier column, which facilitates disassembly and clamping of the clamping component. This simplifies the construction and installation process when the cap beam clamp is reused and improves the flexibility of the cap beam clamping device.

[0025] 2. The present invention provides a clamping device for cap beam construction, which uses a hydraulic cylinder and a support block to clamp the support component to the pier column during support, increasing the friction between the support component and the pier column, reducing the risk of the cap beam clamping device falling off, and increasing safety. When disassembling, the piston rod retracts, and the hydraulic cylinder can rotate along the axis of the mounting lug of the fixed seat. The hydraulic cylinder can be rotated to either side to fold, providing a larger disassembly space.

[0026] 3. The present invention provides a clamping device for the construction of a cap beam, which utilizes the fixed head and the rectangular blind groove on the protruding plate to rotate and snap together. At the same time, the magnetic sheet on the rectangular blind groove and the magnetic sheet on the fixed head are used for adsorption and fixation, which doubles the reinforcement and locking of the clamping component, thus realizing rapid connection.

[0027] 4. The present invention provides a clamping device for cap beam construction. During installation, the upper electromagnetic block drives the shift fork to slide upward, which in turn drives the spline sleeve to slide upward, thereby driving the drive gear and the driven gear to rotate. When the cap beam clamping device is working, the lower electromagnetic block is energized, which separates the spline sleeve and the drive gear, preventing the drive shaft from rotating when the motor is misoperated, and then opening the cap beam clamping device, thus improving the safety of the device.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

The term "connection" simply indicates a connection between devices and has no special meaning.

[0041] Furthermore, the technical fields and installation methods involved in the embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] For specific implementation examples, please refer to: Figure 1 and Figure 2 A clamping device for constructing a cap beam, used to circumferentially fit against a pier column 5 to erect the cap beam, includes a rotating assembly 1, a locking assembly 2, a supporting assembly 3, and a clamping assembly 4. The clamping assembly 4 includes a clamping block 41, a clamping block 42, and at least two clamping blocks 43. The clamping blocks 41, 42, and 43 are all arc-shaped and connected in a ring. Adjacent clamping blocks 43 are hinged together, with one end of the clamping block 43 connected to the clamping block 41. One end is hinged, and the other end of the clamping block 3 43 is hinged to one end of the clamping block 2 42. The other end of the clamping block 1 41 is connected to the other end of the clamping block 2 42 through the locking component 2. Multiple rotating components 1 are provided, and the multiple rotating components 1 are respectively connected to the hinge structure of the clamping component 4. The locking component 2 is inserted into the clamping component 4, and the locking component 2 and the clamping component 4 are rotatably snapped together. The support component 3 is set inside the clamping component 4, and the support component 3 and the clamping component 4 are rotatably connected.

[0043] In this embodiment, there are two clamping blocks 3 43, one of which is hinged to clamping block 1 41, and the other is hinged to clamping block 2 42. The two clamping blocks 3 43 are hinged together, and there are three corresponding rotating components 1.

[0044] Please see Figures 1-4The rotating assembly 1 includes a driven gear 11, an electromagnetic block 12, a shift fork 13, a support shaft 14, a spline sleeve 15, a support frame 16, a motor 17, a drive gear 18, a rotating shaft 19, and a spline shaft 110. The rotating shafts 19 of the multiple rotating assemblies 1 are respectively inserted into the clamping assemblies 4. The end of clamping block 1 41 near clamping block 3 43 is fixedly connected to the rotating shaft 19. The end of clamping block 3 43 near clamping block 1 41 is hinged to the rotating shaft 19. The end of clamping block 2 42 near another clamping block 3 43 is fixedly connected to the rotating shaft 19. The end of another clamping block 3 43 near clamping block 2 42 is hinged to the rotating shaft 19. Adjacent clamping blocks 3 4... One of the three clamping blocks 43 is fixedly connected to the rotating shaft 19, and the other clamping block 43 is hinged to the rotating shaft 19. The support frame 16 is provided with three blocks, which are respectively set on the lower part of the clamping block 41 and the two clamping blocks 43 near the end connected to the rotating shaft 19. The support frame 16 includes a connecting plate 161, a connecting plate 162 and a connecting plate 163. The connecting plate 161 and the connecting plate 162 are both right-angled plates. The lower end of the connecting plate 161 and one end of the connecting plate 162 are connected by bolts. The upper end of the connecting plate 161 is fixedly connected to the clamping assembly 4. The upper end of the connecting plate 162 and one end of the connecting plate 163 are fixedly connected. The support frame 16 is used to support the rotating assembly 1.

[0045] A motor 17 is installed at one end of the upper part of the connecting plate 162, and a support shaft 14 is fixed at the other end. Two electromagnetic blocks 12 are axially spaced on the support shaft 14, and a fork 13 is set between the two electromagnetic blocks 12. One end of the fork 13 is slidably connected to the support shaft 14, and magnets are fixed on the upper and lower sides of the end of the fork 13 that is axially connected to the support shaft 14, for use in conjunction with the electromagnetic blocks 12 to attract them.

[0046] Driven gear 11 is located below clamping assembly 4 and is fixedly connected to rotating shaft 19. Motor 17 is connected to spline shaft 110 via transmission. Spline sleeve 15 is sleeved on the outside of spline shaft 110. Spline shaft 110 and spline sleeve 15 are meshed and slidably connected via spline structure. The other end of shift fork 13 is located in spline groove 151 on spline sleeve 15. Shift fork 13 is rotatably connected to spline sleeve 15. Drive gear 18 is rotatably mounted on top of spline sleeve 15. External spline is provided on the upper side of spline sleeve 15. Internal spline of the same size as external spline is opened on the lower part of drive gear 18. The lower part of drive gear 18 and the upper side of spline sleeve 15 can cooperate via spline structure. Spline sleeve 15 can engage or disengage with drive gear 18 under the action of shift fork 13. Electromagnetic block 12 is located above support shaft 14. When energized, the fork 13 attracts the upper electromagnetic block 12, causing the fork 13 to move upwards and the spline sleeve 15 to move upwards. The outer spline at the upper end of the spline sleeve 15 enters the inner spline on the drive gear 18, thus engaging and transmitting power between the spline sleeve 15 and the drive gear 18. This allows the motor 17 to drive the drive gear 18 to rotate, thereby rotating the corresponding clamping block. When the electromagnetic block 12 above the support shaft 14 is de-energized and the electromagnetic block 12 below is energized, the electromagnetic block 12 below the support shaft 14 attracts the fork 13 to move downwards, causing the spline shaft 110 to disengage from the drive gear 18. Thus, when the motor 17 drives the spline shaft 110 to rotate, the drive gear 18 does not rotate, thereby preventing the motor 17 from accidentally opening the clamping device for the cap beam construction and improving the safety of the device.

[0047] Since there are three rotating components 1, the entire clamping assembly 4 can be rotated and opened in multiple positions. Depending on the diameter of the pier column 5, the rotating component 1 between clamping block 1 41 and clamping block 3 43 can be selectively driven, or the rotating component 1 between clamping block 2 42 and clamping block 3 43 can be driven to achieve the first position operation; or the rotating component 1 between clamping block 1 41 and clamping block 3 43, and the rotating component 1 between clamping block 3 43 and clamping block 2 42 can be driven simultaneously to achieve the second position operation; or all three rotating components 1 can be driven simultaneously to achieve the third position operation. This facilitates the disassembly and clamping of the clamping assembly 4 and simplifies the construction and installation process of the clamping device used in subsequent cap beam construction when it is reused.

[0048] Please see Figure 8The clamping block 41 includes a movable support plate 411, a reinforcing plate 412, and an extension plate 413. The body of the clamping block 41 is a quarter-ring shape. The support plate 411 is located at the upper center of the clamping block 41. The support plate 411 is used to support the formwork support erected during the construction of the cap beam. Two right-angled reinforcing plates 412 are spaced apart below the support plate 411. The reinforcing plates 412 are fixedly connected to the outer side of the clamping block 41 and are used to strengthen the support. The extension plate 413 is located at the end of the clamping block 41 away from the rotation axis 19. A horizontal rectangular through groove 414 is provided on the protruding plate 413. Several rectangular through grooves 414 are evenly arranged in a direction parallel to the axis of the clamping block 41. A rectangular blind groove 415 is vertically arranged along the middle of the rectangular through groove 414. The rectangular blind groove 415 is located on the side of the protruding plate 413 away from the clamping block 42. The rectangular blind groove 415 does not penetrate the protruding plate 413. A magnetic sheet is installed on the rectangular blind groove 415. The number of rectangular blind grooves 415 is the same as that of the rectangular through grooves 414. The rectangular blind grooves 415 and the rectangular through grooves 414 are in a cross shape.

[0049] Please see Figure 9 and Figure 10 The second clamping block 42 includes fixing holes 421, an extension plate 422, a support plate 423, and a reinforcing plate 424. The body of the second clamping block 42 is a quarter-ring shape. The extension plate 422 is fixed at one end of the second clamping block 42 away from the rotation axis 19. Several fixing holes 421 are evenly distributed on the extension plate 422 along a direction parallel to the axis of the second clamping block 42. The position and number of fixing holes 421 correspond one-to-one with the rectangular through slots 414. The support plate 423 is provided in the middle of the upper part of the second clamping block 42. Two right-angled reinforcing plates 424 are provided at intervals below the support plate 423. The reinforcing plates 424 and the second clamping block 424 are connected. The outer side of 42 is fixedly connected. The second support plate 423 and the second reinforcing plate 424 are the same in shape and size as the first support plate 411 and the first reinforcing plate 412, respectively. The third clamping block 43 includes the third support plate 431 and the third reinforcing plate 432. The body of the third clamping block 43 is a quarter ring. The third support plate 431 is provided in the middle of the upper part of the third clamping block 43. Two right-angled reinforcing plates 432 are provided at intervals below the third support plate 431. The third reinforcing plate 432 is fixedly connected to the outer side of the third clamping block 43. The third support plate 431 and the third reinforcing plate 432 are the same in shape and size as the first support plate 411 and the first reinforcing plate 412, respectively.

[0050] Please see Figure 1 and Figure 5The locking assembly 2 includes a pin 21 and a support sleeve 22. The support sleeve 22 is sleeved on the outside of the pin 21, and the pin 21 and the support sleeve 22 are slidably connected. The support sleeve 22 is inserted into the extension plate 422 of the clamping block 2 42, and the other end of the support sleeve 22 abuts against the extension plate 413 of the clamping block 1 41. A spring 212 is sleeved on the outside of the pin 21, and the head of the pin 21 abuts against one end of the spring 212. The other end of the spring 212 abuts against one end of the support sleeve 22. A fixing head 211 is threadedly connected to the side of the pin 21 away from the support sleeve 22. The fixing head 211 is rectangular, and a magnetic sheet 2 is fixed to the side of the fixing head 211 near the spring 212. The side of the fixing head 211 near the spring 212 abuts against the extension plate 413. The pin 21 can be inserted or removed by passing through the rectangular through slot 414. Rotating the pin 21 will engage the fixing head 211 in the rectangular blind slot 415. The magnetic piece 2 on the fixing head 211 will attract the magnetic piece 1 on the rectangular blind slot 415, thus fixing the pin 21. The position and number of the pins 21 correspond one-to-one with the position and number of the rectangular through slot 414. The locking assembly 2 has several evenly distributed along the direction parallel to the axis of the clamping assembly 4. This arrangement uses the fixing head 211, spring 212 and support sleeve 22 to reinforce and lock the clamping assembly 4. At the same time, the magnetic pieces are used for locking to prevent the pin 21 from falling off the clamping block 41. Moreover, the support sleeve 22 acts as a limit for the clamping block 41 and clamping block 42 after they are retracted, preventing excessive rotation.

[0051] Please see Figure 2 and Figure 7 The support assembly 3 includes a support block 31 and a hydraulic cylinder 32. The support block 31 is arc-shaped, and a rectangular boss is provided on the protruding side of the support block 31. A mounting ear is provided on the rectangular boss. The mounting ear on the support block 31 is rotatably connected to one side of the piston rod of the hydraulic cylinder 32. A fixing seat is fixedly connected to the middle of the clamping block 41, clamping block 42, and clamping block 43. A mounting ear is fixed on the side of the fixing seat away from the clamping assembly 4. The mounting ear is rotatably connected to the hydraulic cylinder 32. The support block 31 is connected to the clamping assembly 4 through the hydraulic cylinder 32. The concave side of the support block 31 abuts against or separates from the pier column 5. The device utilizes support block 31 and hydraulic cylinder 32 to clamp the support assembly 3 onto the pier 5 during support, increasing the friction between the support assembly 3 and the pier 5 and reducing the risk of the clamping device for the cap beam construction falling off. When disassembling the clamping assembly 4, the corresponding clamping block rotates away from the axis of the pier 5, and the hydraulic cylinder 32 actuates to make the piston rod continue to extend and press against the pier 5. When the clamping assembly 4 is supported stably by other construction facilities, it further prevents the clamping device for the cap beam construction from falling off, and the piston rod retracts. At the same time, the hydraulic cylinder 32 can rotate along the mounting lug 2 on the fixed seat, providing more disassembly space.

[0052] This application provides a construction method for a clamping device used in the construction of cap beams, applicable to the aforementioned clamping device for cap beam construction, comprising the following steps:

[0053] S1: First, adjust the position of the four hydraulic cylinders 32 so that the four support blocks 31 are concentric with the first clamping block 41, the second clamping block 42 and the two third clamping blocks 43 respectively, and the hydraulic cylinders 32 are inclined between the support blocks 31 and each clamping block.

[0054] This setup allows for clearance when the clamping component 4 is installed onto the pier 5, providing ample construction space.

[0055] S2: According to the construction requirements, select and start clamping block 1 41 and clamping block 3 43, adjacent clamping block 2 42 and clamping block 3 43, and at least one rotating component 1 between two adjacent clamping blocks 3 43. Power on the electromagnetic block 12 fixed above the support shaft 14. The electromagnetic block 12 above attracts the fork 13 to slide upward and drive the spline sleeve 15 to slide upward and mesh with the drive gear 18. Operate the motor 17 to open clamping block 1 41 and clamping block 2 42 or clamping block 1 41, clamping block 2 42 and any clamping block 3 43, and place the clamping device for the cap beam construction at a suitable height on the pier column 5.

[0056] S3: Reverse start of rotating component 1 in S1, so that clamping block 1 41, clamping block 2 42 and two clamping blocks 3 43 close into a ring, so that protruding plate 1 413 and protruding plate 2 422 are aligned. When closed, support sleeve 22 limits clamping block 1 41.

[0057] S4: Insert pin 21 into rectangular through slot 414 and rotate it 90 degrees so that fixing head 211 engages with rectangular blind slot 415 and is fixed by electromagnetic adsorption.

[0058] S5: Adjust the position of the four hydraulic cylinders 32 so that they are directly opposite the center of the pier 5, extend the piston rod, and let the support block 31 press against the pier 5;

[0059] S6: Operate the rotating assembly 1 below clamping block 1 41 and clamping block 2 42 to energize the electromagnetic block 12 fixed below the spline sleeve 15. The electromagnetic block 12 below attracts the fork 13 to slide downward, separating the spline sleeve 15 and the drive gear 18, thus protecting the motor 17 from misoperation when the clamp is working.

[0060] S7: After installation, a formwork support can be erected above the support plate 411 for the construction of the cap beam.

[0061] After construction is completed, dismantle the formwork support and dismantle the cap beam construction clamp device step by step in reverse according to the above operation steps. Rotate the fixing head 211 to align it with the rectangular through slot 414, separate the pin 21 from the protruding plate 413, and let the hydraulic cylinder 32 continue to press against the pier 5. Start the rotating component 1 in S1, energize the electromagnetic block 12 above the support shaft 14, so that the fork 13 moves upward and drives the outer spline of the spline sleeve 15 to mesh with the inner spline of the drive gear 18. Operate the motor 17 to make the drive gear 18 drive the driven gear 11 to rotate, open the clamping block 41 and clamping block 42 or clamping block 41, clamping block 42 and any clamping block 43, operate the hydraulic cylinder 32 to retract the support block 31, and remove the cap beam construction clamp device from the pier 5.

[0062] In summary, by using a clamp device for cap beam construction to support the pier column 5 to build the cap beam, the friction between the support component 3 and the pier column 5 is increased, reducing the risk of the clamp device falling off and increasing safety. The clamp device utilizes the rectangular blind groove 415 on the fixed head 211 and the extension plate 413 for rotatable engagement, and simultaneously uses the magnetic plate 1 on the rectangular blind groove 415 and the magnetic plate 2 on the fixed head 211 for adsorption and fixation, thus doubly reinforcing and locking the clamping component 4, achieving rapid connection. The clamping component 4 and the support component 3 can be combined to adjust the installation space, adapting to pier columns 5 of different sizes, thereby improving the flexibility of the clamp device for cap beam construction.
