Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure processing technology, specifically to an I-beam repair bracket. Background Technology
[0002] Steel structure is a type of building structure mainly composed of steel materials. It consists of components made of steel profiles and steel plates, such as steel beams, steel columns, and steel trusses, and uses rust removal and prevention processes such as silanization and pure manganese phosphating.
[0003] For some I-beams that need to be spliced or assembled, welding operations are required. Commonly used welding processes include manual electric arc welding, gas shielded welding, and submerged arc welding. The appropriate welding process should be selected based on factors such as the material, thickness, welding position, and production efficiency of the I-beam.
[0004] During the welding process, welding parameters such as welding current, voltage, and welding speed must be strictly controlled to ensure welding quality. At the same time, the weld must be visually inspected and non-destructive tested, such as ultrasonic testing and radiographic testing, to detect whether there are any defects inside the weld.
[0005] If defects exist, manual welding is required. Typically, defective products are selected after inspection, hoisted to an open area by a crane, and then manually rotated and welded onto the I-beams. This process is labor-intensive and carries a risk of injury during rotation. Therefore, an I-beam repair bracket is proposed to address the aforementioned problems. Utility Model Content
[0006] The purpose of this utility model is to provide an I-beam repair bracket to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] An I-beam repair bracket includes two brackets with identical structures, and the I-beam is assembled between the two brackets.
[0009] The support includes clamping components and flipping components;
[0010] The flipping component includes a support, a rotating ring, worm gear teeth, a worm, and a flipping crank. The support has a rotatable rotating ring installed inside, and the outer side of the rotating ring is provided with evenly distributed worm gear teeth. The support has a worm that meshes with the worm gear teeth, and the worm has a flipping crank installed on the worm. The rotating ring has a clamping component that can clamp the I-beam.
[0011] As a further embodiment of this utility model: the clamping component includes two lead screws, a drive ring, a gripper, a drive box, and a clamping crank. The lead screws are rotatably mounted in the rotating ring via bearings. The end of the lead screw away from the drive box is rotatably connected to the drive box via a bearing. The clamping crank is mounted on the drive box. The drive ring is threadedly connected to the lead screw. The clamping crank drives the drive ring to move via the drive box. The gripper is mounted on the drive ring.
[0012] As a further improvement of this utility model: the drive box is equipped with three meshing bevel gears, which are fixed to two lead screws and a clamping crank respectively. The three bevel gears drive the two lead screws to move synchronously through mutual transmission.
[0013] As a further improvement of this utility model: the rotating ring is provided with a vertical shaft inside, which is slidably connected to the two driving rings, and the vertical shaft is fixed to the driving box.
[0014] As a further improvement of this utility model: the two brackets are divided into a main bracket and a secondary bracket. Compared with the main bracket, the secondary bracket lacks a flipping component and is only equipped with a clamping component.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This I-beam repair bracket uses clamping components to install the I-beam between the main bracket and the secondary bracket. The main bracket flips the I-beam using a flipping component, and the secondary bracket rotates accordingly. The operation is simple and convenient. During the welding process, it can efficiently and labor-savingly flip the I-beam, while also improving the safety of the operation. Attached Figure Description

[0021] Please see Figures 1-3 In this embodiment of the utility model, an I-beam repair bracket includes two brackets with identical structures, and the I-beam is assembled between the two brackets.
[0022] The support includes clamping components and flipping components;
[0023] The tilting mechanism includes a support 1, a rotating ring 2, worm gear teeth 11, a worm 12, and a tilting crank 9. The support 1 houses a rotatable rotating ring 2, with evenly distributed worm gear teeth 11 on its outer side. The support 1 contains a worm 12 that meshes with the worm gear teeth 11, and the tilting crank 9 is mounted on the worm 12. The rotating ring 2 houses a clamping component for holding the I-beam. The overhead crane lifts the I-beam to an open area with two pre-set supports. The I-beam is lifted between the two supports. The tilting mechanism rotates the clamping component to a horizontal position, the overhead crane lifts the I-beam in, and the clamping component is manually operated to hold the I-beam. The worm gear 12 is fixed and connected to the rotating crank 9. The rotating crank 9 is manually rotated to control the rotation of the I-beam. The drive mechanism of the worm gear 12 and the worm wheel 11 has a self-locking function. The operator can only drive the rotating ring 2 to rotate by rotating the crank 9. The rotating ring 2 cannot rotate freely to change the angle of the I-beam. This keeps the I-beam stable during the welding process and prevents the I-beam from rotating during welding. This rotation method is simple and labor-saving to operate. The equipment is lightweight, convenient and portable. It can be used for welding I-beams of different lengths and specifications, effectively improving the safety and efficiency of the operation.
[0024] In a preferred embodiment, the clamping component includes two lead screws 3, a drive ring 4, a jaw 8, a drive housing 5, and a clamping crank 7. The lead screws 3 are rotatably mounted in the rotating ring 2 via bearings. The end of the lead screw 3 away from the drive housing 5 is rotatably connected to the drive housing 5 via a bearing. The clamping crank 7 is mounted on the drive housing 5. The drive ring 4 is threadedly connected to the lead screw 3. The clamping crank 7 drives the drive ring 4 to move via the drive housing 5. The jaw 8 is mounted on the drive ring 4. As a fixing component for the H-beam, the clamping component needs to have good strength and clamping force. Therefore, the clamping method of using lead screws 3 to drive the jaw 8 is adopted. The clamping surface of the jaw 8 on the H-beam can be the two flanges or the web. It is also applicable to the welding repair of H-beams. The jaw 8 can be set as an inwardly extending protrusion to reduce the clamping distance and meet the clamping distance of the web. Compared with clamping the flanges, clamping the web results in the most stable fixation of the H-beam.
[0025] In a preferred embodiment, the drive box 5 is provided with three meshing bevel gears 6. The three bevel gears 6 are fixed to two lead screws 3 and a clamping crank 7 respectively. The three bevel gears 6 drive the two lead screws 3 to move synchronously through mutual transmission. Through the meshing transmission of the three bevel gears 6, the two lead screws 3 can be driven to rotate synchronously in opposite directions, which meets the action requirements of synchronous clamping and synchronous separation of the gripper 8.
[0026] In a preferred embodiment, the rotating ring 2 is provided with a vertical shaft 10, which is slidably connected to the two drive rings 4. The vertical shaft 10 is fixed to the drive box 5. The rotation of the lead screw 3 will drive the drive ring 4 to rotate, thereby affecting the working efficiency of the drive ring 4 sliding up and down. Therefore, the vertical shaft 10 is set to restrict the rotation of the drive ring 4 so that it can only move vertically up and down.
[0027] In a preferred embodiment, the two supports are divided into a main support and a secondary support. Compared with the main support, the secondary support lacks a flipping component and is only equipped with a clamping component. During the driving process, the flipping component of the main support will drive the I-beam to rotate, thereby driving the secondary support on the other side to rotate. Therefore, the secondary support does not need to be equipped with a flipping component. If the secondary support is equipped with a flipping component, operators at both ends need to operate simultaneously, which will cause inconvenience. Therefore, it is most reasonable for the secondary support to only be equipped with a freely rotatable clamping component.
[0028] It should be noted that all the above embodiments belong to the same utility model concept, and the descriptions of each embodiment have different focuses. Where the description in a particular embodiment is not detailed, please refer to the description in other embodiments.
[0029] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
