Description

Technical Field

[0001] This invention relates to the field of component support device technology, and in particular to a support and fixing device for cylindrical components and its method of use. Background Technology

[0002] When storing and transporting cylindrical components, the cylindrical body needs to be fixed at specific locations. Traditional cylindrical component fixing brackets consist of two semicircles forming a closed circle or near-circle. The lower semicircle is connected to the support frame. During operation, screws or bolts are used to connect the upper and lower semicircles together, or union bolts are used to connect the two semicircles together. At the same time, the two semicircles are tightly fitted to the cylindrical surface of the cylindrical component, and the clamping force is converted into frictional force, ensuring that the cylindrical component cannot move along the axial direction of the cylindrical component and ensuring transportation safety. However, the traditional fixing method requires the cylindrical component to be raised above the horizontal center line of the lower semicircle when installing and disassembling the cylindrical component, which poses certain safety hazards. Furthermore, the bolts need to be unscrewed when separating the two semicircles, resulting in low disassembly and assembly efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a support and fixing device for cylindrical components and its usage method.

[0004] The technical solution adopted in this invention is: A support and fixing device for a cylindrical component includes a support beam and fixing brackets disposed at both ends of the support beam; The fixed bracket includes a support body, a support block, a swing pressure plate, a pressing block, a locking screw, a pad, and a locking plate; the support block is an arc-shaped block, and the support blocks are symmetrically arranged at both ends of the support body; The swing pressure plate has a crescent-shaped structure. The two swing pressure plates are arc-shaped and opposite each other, and their lower ends are respectively hinged to the support body ends on the outside of the two support blocks by pins. The clamping block is also an arc-shaped block. The two clamping blocks are respectively set on the upper ends of the two swing pressure plates by locking screws. The pads are respectively set on the support block and the clamping block. The upper end of the locking plate is provided with an L-shaped hole, and the swing pressure plate is provided with a positioning shaft B. The upper ends of the two locking plates are slidably connected to the positioning shaft B of the swing pressure plate on the corresponding side through the L-shaped hole; the lower ends of the locking plates are hinged to the support plate through the positioning shaft A.

[0005] Specifically, the support beam is a frame structure welded from channel steel profiles, and crossbeams for fixing bracket installation are provided at both ends of the support beam frame.

[0006] More specifically, the support body includes a base plate and two support plates symmetrically arranged in the middle of the base plate. The base plate is installed on the crossbeam of the support beam by screws. The upper end of the support plate is arc-shaped, and an arc-shaped mounting groove is formed between the two support plates.

[0007] More specifically, the outer arc surface of the support block has a rectangular protrusion along the circumferential direction at the center, which matches the arc-shaped mounting groove. Screws pass through the support plate and the rectangular protrusion to set the support block on both ends of the support plate. The outer arc surface of the clamping block has a rectangular groove along the circumferential direction for cooperating with the swing pressure plate. The inner walls of both the support block and the clamping block have dovetail-shaped protrusions along the circumferential direction for installing the pad. The pad has a dovetail groove that matches the dovetail-shaped protrusion. Limiting plates are installed on both ends of the pad by screws.

[0008] More specifically, the rectangular groove bottom of the outer arc surface of the clamping block is provided with a conical groove, a rotating handwheel is provided on the rear end of the locking screw, and a hemispherical connecting part is provided at the front end. A reducing diameter annular groove is provided between the hemispherical connecting part and the threaded part of the locking screw. After the locking screw is threadedly connected to the swing pressure plate, the front hemispherical connecting part is located in the conical groove of the clamping block. A fixing hole is provided on the side of the clamping block corresponding to the reducing diameter annular groove. A screw is provided in the fixing hole, and the front end of the screw is located in the reducing diameter annular groove to connect the clamping block to the locking screw.

[0009] A method for using a support and fixing device for a cylindrical component, specifically as follows: S1: Install the fixed brackets on both ends of the support beam through the base plate of the support body; during transportation operations, fix the crossbeam of the assembled fixed device to the transportation equipment. S2: Place the cylindrical component on the support blocks of the two fixed brackets. The lower two outer walls of the cylindrical component are in close contact with the arc surfaces of the pads on the support blocks. Rotate the swing plates on both sides around the positioning axis A to move them closer to the cylindrical component. After closing, the positioning axis B is located inside the lower end of the L-shaped hole of the locking plate. Adjust the clamping block within the assembly gap between the rectangular groove of the clamping block and the swing plate so that the arc surfaces of the pads on the clamping block are in close contact with the upper two outer walls of the cylindrical component. S3: By turning the handwheel and tightening the locking screws respectively, the pads on the clamping block are tightly fitted to the outer walls on both sides of the upper part of the cylindrical component product, generating radial pressure to press the cylindrical component product. Under the action of friction, the cylindrical component product is fixedly installed. S4: When the transportation operation is completed or the cylindrical component needs to be transferred, loosen the rotating handwheel. After the force on the clamping block is eliminated, open the swing pressure plate outward and push the locking plate inward. The positioning shaft B slides to the upper part of the L-shaped hole of the locking plate, so that the swing pressure plate opens completely outward and the cylindrical component can be smoothly moved out of the fixed bracket.

[0010] Due to the adoption of the technical solution described above, the present invention has the following advantages: The present invention features a reasonable structure, high fit, and quick and convenient assembly and disassembly. The L-shaped hole on the locking plate, after contacting the positioning shaft B to generate pressure and lock the cylindrical product, will not loosen and cause clamping failure. Furthermore, when the positioning shaft B is positioned above the L-shaped hole, the two swing pressure plates are fully opened, lowering the lifting center of gravity compared to traditional semi-circular fixing devices, ensuring safe and reliable lifting. Replaceable pads are provided on the clamping block and support block, facilitating replacement after aging or damage and extending the service life of the fixing device. All components are flexibly connected, preventing parts from scattering compared to fixed devices with separate transmission mechanisms. Multiple fixing brackets can be set according to the size of the cylindrical component product, offering strong adaptability and a wide range of applications. Attached Figure Description
