Description

Technical Field

[0001] The invention relates to the technical field of engineering clamp installation platforms, and in particular to an adjustable clamp installation and disassembly platform for engineering. Background Art

[0002] At present, the clamp device can tightly clamp two semicircular steel hoops on the surface of cylindrical piers (such as concrete piers) with the pre-tightening force applied by high-strength bolts, thereby generating a stable friction force. It replaces the traditional bracket support system (such as full-height brackets or floor-standing brackets) and builds a stable and reliable load-bearing work platform for various subsequent construction processes.

[0003] However, there are many inconveniences in the existing installation process, such as relying on manual methods to install the clamps, and there are many bolts and the tightening strength is high. This process not only consumes a lot of manpower and time, but also requires special attention during the installation process to ensure that the torque of each installation bolt is evenly distributed. Manual operation often cannot meet the high-precision installation requirements, thus affecting the overall installation quality and efficiency. The reason is: loose bolts will cause the friction between the clamp and the concrete column to decrease, and the construction load cannot be effectively transmitted. For example, the initial friction design value is 100kN, which may drop to 60kN after loosening, directly threatening the safety of the structure. Risk of connection failure: Severe loosening may cause the clamp to slip, causing the overall structure to become unstable, leading to construction accidents.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Air is transported into the second piston cylinder, thereby driving the second piston to move. The movement of the second piston drives the movable rod and the second fixed block to move. The movement of the second fixed block drives the moving plate of the clamp to move. Finally, the clamp is buckled on the outside of the concrete column and the two clamps are against each other. In this way, the support and installation of the clamp are achieved, which reduces manual participation and reduces labor intensity.

[0017] 2. Air is transported into the first piston cylinder, which in turn drives the first piston in the first piston cylinder to move. The movement of the first piston drives the drive rod to move.

In this way, the bolts and nuts are in place for subsequent installation.

[0018] 3. Since air is compressible, when there is no threaded engagement between the bolt and the nut, the opposing force generated by the two will be fed back to the drive rod and the first piston. In this way, the air can be compressed, and the strong engagement of the bolt and nut will not cause damage to the thread, thereby protecting the nuts and bolts.

[0019] 4. Since multiple driving rods rotate synchronously, multiple bolts can rotate synchronously and engage with nuts, thereby realizing rapid installation of the clamp and improving installation efficiency. Since the bolts are installed synchronously and driven by driving rods with rotating speed, the torque after installation is the same, ensuring the quality of installation.

[0020] 5. Open the control valve and let the air out through the exhaust pipe. Under the action of the first spring and the second spring, the driving rod and the clamp moving plate are reset, so that the entire device is separated from the installed clamp.

[0021] 6. Drive the hexagonal groove at the end of the driving rod to cover the bolt and nut, start the motor to reverse it, and open the control valve at the same time. The air is slowly discharged through the exhaust pipe. The bolt is rotated to separate it from the nut, thereby realizing the disassembly of the clamp.

[0022] In summary, the present invention uses gas to drive the movement of bolts and nuts and the installation of clamps, and utilizes the compressibility of air to realize the core of the bolts and nuts, while also avoiding the strong engagement of the thread, thereby protecting the bolts and nuts, and ensuring the consistency of the installation torque while achieving the installation of multiple bolts, thereby improving work efficiency and ensuring the quality of installation.

[0027] Two sets of driving mechanisms and two sets of fixing mechanisms are provided on the clamp movable plate 4. The driving mechanism is arranged corresponding to the fixing mechanism. The driving mechanism includes a first mounting frame 17 fixed on the clamp movable plate 4. The first piston cylinder 39 on the driving mechanism is rotatably mounted with the first mounting frame 17. The multiple first piston cylinders 39 of this part rotate synchronously.

The rotating bolt engages with the nut placed in the hexagonal groove to fix the two hoops together and make the torque of multiple bolts the same.

[0033] It also includes a pushing mechanism for driving the clamp movable plate 4 to move, the pushing mechanism includes a first fixed block 5 fixed to the upper end of the lifting platform 1, a second piston cylinder 6 fixedly connected to the first fixed block 5 is penetrated by the first fixed block 5, a second piston cylinder 6 is slidably connected in the second piston cylinder 6, a second spring 38 is fixed to the second piston 42 and the second piston cylinder 6, a delivery pipe 9 is fixed to the second piston cylinder 6, the delivery pipe 9 is connected to the air supply box 2, a movable rod 8 is fixed to the second piston 42, a second fixed block 7 is fixed to the clamp movable plate 4, and the movable rod 8 is fixedly connected to the second fixed block 7.

[0034] It also includes an air supply mechanism for supplying air to the air supply box 2, the air supply mechanism includes a movable plate 24 that moves synchronously with the clamp movable plate 4, the third piston cylinder 13 and the support plate 12 are installed on the movable plate 24, the motor 11 is fixed on the support plate 12, the output end of the motor 11 is fixed with a drive shaft 25, the drive shaft 25 is fixedly connected with a circular plate 27, the circular plate 27 is eccentrically hingedly connected with a connecting rod 26, the third piston 19 is movably connected in the third piston cylinder 13, the connecting rod 26 is hingedly connected to the third piston 19, an air inlet pipe 29 and an air outlet pipe 31 are installed on the third piston cylinder 13, the air outlet pipe 31 is connected to the air supply box 2, an air inlet check valve 28 is installed on the air inlet pipe 29, the air inlet check valve 28 only allows air to enter the third piston cylinder 13 through the air inlet pipe 29; an air outlet check valve 30 is installed on the air outlet pipe 31, the air outlet check valve 30 only allows air to flow through the third piston cylinder 13 to the air outlet pipe 31.

[0035] The transmission mechanism also includes a transmission mechanism, which includes a third sprocket 32 ​​fixed on the drive shaft 25 and the first piston cylinder 39 , and the two third sprockets 32 are connected by a third chain 33 .

[0036] An exhaust pipe 14 is installed on the air supply box 2, and a control valve 15 is installed on the exhaust pipe 14. This part is used to prepare for removing the device after the bolts are installed.

[0037] When the present invention is in use, the lifting platform 1 can be lifted and lowered by the lifting frame, the bridge pillar is located inside the lifting platform 1, and then the clamp to be installed is placed in the clamp placement groove 22, the lifting platform 1 is driven to move upward, and when it moves to the required installation position, the lifting and lowering of the lifting platform 1 is stopped. The staff can also be on the lifting platform 1, and then place the bolt to be installed in the hexagonal groove located at the first mounting frame 17, and the nut is placed in the hexagonal groove on the other side.

[0038] Start the motor 11, and the output end of the motor 11 drives the driving shaft 25 to rotate. The rotation of the driving shaft 25 drives the circular plate 27 to rotate. The rotation of the circular plate 27 cooperates with the connecting rod 26 to realize the reciprocating movement of the third piston 19 in the third piston cylinder 13. When the third piston 19 moves close to the circular plate 27, the external air can be sucked into the third piston cylinder 13 through the air inlet pipe 29. When the third piston 19 is away from the circular plate 27, the internal air can be transported to the air supply box 2 through the air outlet pipe 31.

[0039] As the air in the air supply box 2 increases, the air is transported to multiple first piston cylinders 39 through the connecting pipe 16, and then transported to the second piston cylinder 6 through the delivery pipe 9. Since there are multiple first piston cylinders 39 and each of them has a first spring 23 inside and the elastic force of the first spring 23 is greater than the elastic force of the second spring 40, a greater resistance is generated to the air. Therefore, the air is preferentially transported to the second piston cylinder 6, thereby driving the second piston 42 to move. The movement of the second piston 42 drives the movable rod 8 and the second fixed block 7 to move. The movement of the second fixed block 7 drives the clamp movable plate 4 to move. Finally, the clamp is buckled on the outside of the concrete column and the two hoops are against each other.

[0040] Since the clamp cannot move, it will be fed back to the clamp moving plate 4, the second fixed block 7 and the movable rod 8, so that the second piston 42 cannot move, and the gas continues to be transported into the air supply box 2. The air will be transported into the first piston cylinder 39, and then drive the first piston 40 in the first piston cylinder 39 to move. The movement of the first piston 40 drives the drive rod 41 to move, and the movement of the drive rod 41 drives the bolt and the nut to move. Finally, the nut is against the clamp and faces the mounting hole on the clamp, and the bolt faces the clamp and faces the mounting hole.

[0041] The rotation of the drive shaft 25 drives the third sprocket 32 ​​to rotate, and under the transmission of the third chain 33, the first piston cylinder 39 is rotated. Under the transmission of the first sprocket 34, the first chain 35, the second chain 36, and the second sprocket 37, multiple first piston cylinders 39 are synchronously rotated. The rotation of the first piston cylinder 39 drives the drive rod 41 to rotate, and then drives the bolt to rotate. Since air is compressible, when the bolt and the nut are not threadedly engaged, the offsetting force generated by the two will be fed back to the drive rod 41 and the first piston 40. In this way, the air can be compressed, and the situation of damage to the thread due to the strong engagement of the bolt and the nut will not occur, thereby protecting the nuts and bolts.

[0042] Since multiple driving rods 41 rotate synchronously, multiple bolts can rotate synchronously and engage with nuts, thereby achieving rapid installation of the clamp and improving installation efficiency; since the bolts are installed synchronously and driven by the driving rods 41 with rotating speed, the torque after installation is the same, ensuring the quality of installation.

[0043] As the tightening strength of the bolts increases, the working resistance of the motor 11 increases, the motor 11 is turned off, the control valve 15 is opened, and the air is discharged through the exhaust pipe 14. Under the action of the first spring 23 and the second spring 38, the driving rod 41 and the clamp moving plate 4 are reset, so that the entire device is separated from the installed clamp.

[0044] Then move the lifting platform 1 downward and install another clamp.

[0045] When disassembling, as mentioned above, the hexagonal groove at the end of the driving rod 41 is driven to be sleeved on the bolt and nut, the motor 11 is started to reverse, and the control valve 15 is opened at the same time, and the air is slowly discharged through the exhaust pipe 14. Combined with the rotation of the bolt, it can be separated from the nut, thereby realizing the disassembly of the clamp.

[0046] It should be noted that during installation, the first piston 40 moves first due to the action of the first spring 23. Therefore, during disassembly, the first piston 40 is reset and moved first due to the elastic force of the first spring 23, so that the clamp moving plate 4 can carry the clamp and split it.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
