Description

Technical Field

[0001] This invention belongs to the field of clamping technology, specifically relating to a pier clamping device. Background Technology

[0002] The clamping device consists of a clamp plate, a wing plate, a tie plate, bolts, and an inner liner. There are many types of clamps, such as cable clamps, utility pole clamps, guy wire clamps, suspension wire clamps, and stainless steel clamps, which are commonly used. Chinese patent, publication number CN222100638U, discloses a bridge pier clamping device. By setting a rubber layer, the friction between the steel strip and the pier is increased. At the same time, the rubber layer can be squeezed by squeezing hydraulic oil to increase the clamping force of the rubber layer on the pier, thus preventing the clamp from loosening. Existing clamps come in various sizes, customized according to the dimensions of the bridge piers to be installed. Therefore, when the bridge piers are large, the clamps will also be large and heavy. When workers install clamps, they usually install clamp accessories below the clamp installation point to facilitate installation and positioning. However, existing clamp accessories are usually fixed to the bridge piers using bolts or other structures, making the installation and removal of clamp accessories quite laborious. On the other hand, using hoisting methods to install clamps results in poor installation stability. Summary of the Invention

[0003] To address the problem of laborious installation of clamps in existing technologies, this invention provides a pier clamp device. This device utilizes a support cylinder combined with a telescopic rod to support the clamp during installation and facilitates easy disassembly of the support components from the clamp. The specific technical solution is as follows: A pier clamp device includes a bridge pier. Two clamp components are mounted on the bridge pier. Multiple T-shaped plates are equidistantly installed at the bottom of each clamp component. Sleeve blocks are slidably fitted onto the T-shaped plates. A T-shaped hole is formed at the top of each sleeve block, and both ends of the T-shaped hole are open. Support cylinders are fixedly installed on the bottom of the sleeve block on both sides. A telescopic rod is slidably connected inside the support cylinder. The bottom of the telescopic rod extends out of the support cylinder. A strip-shaped hole is opened on the outer wall of the support cylinder. The strip-shaped hole is opened in the vertical direction. A sliding rod is slidably connected inside the strip-shaped hole. One end of the sliding rod is fixedly connected to the telescopic rod. The other end of the sliding rod extends out of the strip-shaped hole. The other end of the sliding rod is studded. A second knob is threaded onto the other end of the sliding rod. The second knob is used to fix the telescopic rod.

[0004] Preferably, the clamp component includes: a clamp, a support plate, bolts, and a reinforcing plate. There are two clamps, and a support plate is fixedly installed at both ends of the clamp. The support plates correspond one-to-one and are fixed to each other by bolts. A reinforcing plate is connected between the support plate and the outer wall of the clamp.

[0005] Preferably, the outer wall of the clamp is provided with multiple lifting ring components, and the multiple lifting ring components are located at the same height.

[0006] Preferably, the lifting ring component includes: an arc-shaped groove and an outer slider. The outer wall of the clamp is provided with multiple arc-shaped grooves. The surface of the arc-shaped groove is slidably connected to the outer slider. The outer wall of the outer slider is fixedly installed with a mounting base. The middle of the mounting base is rotatably connected to a connecting block. The outer wall of the connecting block is threaded with a lifting ring. The lifting ring is compatible with external lifting equipment.

[0007] Preferably, a T-shaped groove is formed on the outer wall of the arc-shaped groove, and a connecting plate is slidably connected in the T-shaped groove. A rotating shaft is fixedly installed in the middle of the connecting plate. The rotating shaft is arranged in a vertical direction, and two rollers are symmetrically mounted at both ends of the rotating shaft. The rollers roll and fit against the inner wall of the T-shaped groove. One end of the connecting plate extends out of the T-shaped groove, and the extended end of the connecting plate is fixedly connected to the outer slider.

[0008] Preferably, the top and bottom of the outer slider are rotatably connected to a first knob. A screw is fixedly installed at the end of the first knob near the outer slider. A movable block is threaded onto the outer wall of the screw. The screw extends rotatably into the outer slider. Two sliding grooves are formed inside the outer slider. The movable block corresponds to each sliding groove and is slidably connected in the sliding groove. A clamping block is fixedly installed at the end of the movable block away from the screw. A slot is formed on the side of the sliding groove near the arc-shaped groove. The clamping block is slidably connected in the slot and is adapted to the arc-shaped groove.

[0009] Preferably, both the moving block and the chute are rectangular structures.

[0010] Preferably, a platform is detachably installed on the outer side of the bridge pier, and a platform lifting ring is installed at each of the four corners of the top of the platform.

[0011] Preferably, a top frame is fixedly installed on the top of the bridge pier. The top frame has a cross-shaped structure. Each of the four plates of the top frame is equipped with a mobile hoist. The output end of the mobile hoist is equipped with a wire rope. The wire rope corresponds one-to-one with the lifting ring of the platform and is connected to the lifting ring of the platform.

[0012] In addition, the pier clamp device in the above-mentioned technical solution provided by the present invention may also have the following features: a baffle is fixedly installed at one end of the T-shaped plate.

[0013] In the above technical solution, the baffle is located on the side close to the center of the clamp component.

[0014] The pier clamping device of the present invention has the following advantages compared with the prior art: This pier clamp device allows for the sliding installation of a support cylinder at the bottom of the clamp. By adjusting the extension length of the telescopic rod according to the required installation height of the clamp, the connection between the clamp and the external hoisting equipment can be disconnected after the support is placed on the platform. This eliminates the need for workers to lift the clamp for installation, saving them a significant amount of installation effort. After the clamp is installed and fixed, workers can remove the support cylinder from the clamp by shortening the telescopic rod, making the entire work process more convenient. This pier clamp device adjusts the distance between two lifting points by moving the outer slider on the arc groove. This makes it easier to lift the clamp onto the platform in a more balanced state when using external lifting equipment. This reduces swaying during lifting and transportation and makes it easier for workers to receive the clamp. Attached Figure Description

[0026] The bridge piers, mobile hoisting equipment, wire ropes, platforms, clamps, bolts, and reinforcing plates in this case are existing technologies. The bolts and reinforcing plates are of the same structure and connection method as those in the cited documents. As long as the bridge piers, mobile hoisting equipment, wire ropes, platforms, clamps, bolts, and reinforcing plates meet the requirements of this case, they are all acceptable and not limited to a single model.

[0027] The specific types or circuit structures of the controllers for the electrical components mentioned in this application, as well as the circuit connection relationships between the electrical components and the accurate coordinated control of multiple power components, are all prior art. Therefore, the above content will not be elaborated upon in this application.

[0028] Working Principle: All electrical components mentioned in this application are externally connected to a power supply and control switch during use. After installation, first check the installation, fixation, and safety precautions before use. During use, connect the wire rope 20 to the platform lifting ring 22. Workers climb onto the platform 21 and then use the movable hoist 19 to raise and lower the platform 21, moving it along the axial direction of the bridge pier 1 until it reaches a suitable height. Then, connect the external crane's lifting rope to the lifting ring 2055 on the clamp 201. Workers slide the outer slider 2052, adjusting its position on the arc groove 2051 to balance the clamp 201. After adjustment, workers rotate the first knob 3, causing the screw 4 to rotate, which in turn moves the moving block 5 within the slide groove 7. The moving block 5 drives the clamping block 8 to move within the slot 6, so that the clamping block 8 is pressed tightly against the outer wall of the arc groove 2051, fixing the outer slider 2052 onto the arc groove 2051. Then, the clamp 201 is lifted onto the platform 21 by a crane. The worker takes the support cylinder 11 and puts the sleeves 14 on the support cylinder 11 onto the T-shaped plate 9, so that the sleeves 14 are in contact with the baffle 10. Then, the position of the telescopic rod 12 is adjusted according to the required installation height of the clamp 201. The support seat 13 is placed on the platform 21, and then the second knob 17 is locked to lock and fix the second knob 17 to the support cylinder 11. In this way, the clamp 201 is supported by the support cylinder 11 so that the worker can install the clamp 201. The worker installs the clamp 201 onto the bridge pier 1 and connects and fixes the two support plates 202 with bolts 203, thus installing the clamp 201 onto the bridge pier 1.

[0029] After the clamp 201 is installed, the staff loosens the second knob 17 to unlock the telescopic rod 12 and the support cylinder 11. The staff can then slide the telescopic rod 12 to disengage the support seat 13 from the platform 21. Then the sleeve block 14 can be removed from the T-shaped plate 9 to achieve quick disassembly and assembly of the support cylinder 11.
