Description

Technical Field

[0001] This invention relates to the field of splicing equipment technology, and more specifically, to a rod splicing device. Background Technology

[0002] In recent years, the steel structure market has continued to expand, and the size of steel structures and their components has become increasingly larger. However, due to transportation conditions, some components still need to be further disassembled to meet transportation requirements. This necessitates an additional assembly process upon arrival at the site, where the disassembled components are reassembled.

[0003] The relevant technology generally involves erecting various supports and templates on a fixed frame to fix half of the members, and then hoisting the other half of the members. The members' positions are adjusted manually and by hinges to control their dimensions. This method is labor-intensive, and the support reuse rate is low. For different members, the original support must be dismantled and re-erected each time. Furthermore, it is difficult to control the position and dimensions of the assembled members with high precision through manual labor and hinges, which makes it difficult to meet the increasingly high precision and quality requirements in steel structure engineering. Summary of the Invention

[0004] The present invention aims to solve at least one of the above-mentioned technical problems.

[0005] This invention provides a rod splicing device, comprising:

[0006] The main structural frame consists of two main structural frames arranged at intervals and symmetrically.

[0007] A support and fixing structure is provided on each of the main structural frames, and the support and fixing structure is used to support and fix the rods to be spliced.

[0008] A flipping mechanism is provided on each of the main structural frames. Each flipping mechanism includes a first support, a second support, and a first telescopic drive device. The main structural frame is hinged to the first support. One end of the first telescopic drive device is hinged to the second support, and the other end is hinged to the main structural frame. The first telescopic drive device drives the main structural frame to rotate along the first support, thereby achieving the flipping and docking of the two members to be spliced.

[0009] An internal support bracket is arranged between the two main structural frames to support the two members to be spliced ​​after they are flipped and joined together.

[0010] The rod splicing device provided by this invention has, but is not limited to, the following beneficial effects compared with the prior art:

[0011] The rod splicing device of this invention is divided into left and right parts, each holding a rod to be spliced. The two rods (the left and right halves of a complete rod) are spliced ​​together to form a single complete rod. In use, two flipping mechanisms unfold the two main structural frames. Specifically, a first telescopic drive device, such as a jack, rotates the main structural frames along a first support, causing the two main structural frames to unfold in a direction away from each other. Then, the two rods to be spliced ​​are respectively hoisted onto the supporting structures on the two main structural frames, and their positions are fixed by the supporting structures. During this process, the reference points for the positions of the two rods to be spliced ​​are ensured to be consistent, so as to ensure the accuracy of the flipping and docking. Then, two flipping mechanisms flip the two main structural frames closer to each other. Specifically, the first telescopic drive device rotates the main structural frames along the first support, causing the two main structural frames to flip closer to each other until the two members to be spliced ​​contact each other and fall onto the inner support bracket. The inner support bracket ensures stable support for the two members to be spliced. Then, the connection parts of the two members to be spliced ​​are assembled by welding. After welding, the fixing of the member to be spliced ​​on one of the main structural frames is released. Then, the two flipping mechanisms unfold the two main structural frames away from each other. Finally, temporary lifting lugs are installed on the spliced ​​members, or other lifting devices are used to lift the members out. Compared with the prior art, the member splicing device of the present invention has the advantages of using a telescopic drive device to rotate and flip the members, which is easier and more accurate than using a crane, manual labor, and hinges. On the other hand, it can adapt to a variety of different members without dismantling and rebuilding the original support for different members. The overall splicing process requires less labor and has higher splicing accuracy and quality.

The position of the fixing device on the first pad and the second pad is adjustable. The fixing device is used to limit the position of the rod to be spliced. The two ends of the connecting rod are respectively connected to the fixing device on the first pad and the second pad. The connecting rod is used to contact and support the rod to be spliced.

[0014] Optionally, the fixing device includes a flat plate, an ear plate, and a U-shaped clamp.

One end of the second telescopic drive device is connected to one end of the main structural frame, and the flat baffle is connected to the other end of the second telescopic drive device.

[0034] like Figures 1 to 3 As shown, the rod splicing device of this invention includes:

[0035] Main structural frame 1, two main structural frames 1 are spaced apart and symmetrically arranged;

[0036] A support and fixing structure 2 is provided on each of the main structural frames 1. The support and fixing structure 2 is used to support and fix the rods 100 to be spliced.

[0037] A flipping mechanism 3 is provided on each of the main structural frames 1. The flipping mechanism 3 includes a first support 31, a second support 32, and a first telescopic drive device 33. The main structural frame 1 is hinged to the first support 31. One end of the first telescopic drive device 33 is hinged to the second support 32, and the other end is hinged to the main structural frame 1. The first telescopic drive device 33 drives the main structural frame 1 to rotate along the first support 31, thereby achieving the flipping and docking of the two members 100 to be spliced.

[0038] An inner support bracket 4 is arranged between the two main structural frames 1 to support the two members 100 to be spliced ​​after they are flipped and joined together.

[0039] In this embodiment, in conjunction with the appendix Figure 1 To be continued Figure 3 As shown, this rod splicing device is divided into left and right (attached) Figure 1 The structure consists of two parts (in the X-axis direction), each containing a member 100 to be assembled. These two members 100 (the left and right halves of a complete member) are then joined together to form a single complete member. In use, the two main structural frames 1 are unfolded via two flipping mechanisms 3. Specifically, the first telescopic drive device 33 rotates the main structural frames 1 along the first support 31 (hinged fulcrum), causing the two main structural frames 1 to unfold in directions away from each other, as shown in the attached diagram.

During this process, the reference points of the positions of the two members 100 to be spliced ​​are kept consistent to ensure the accuracy of the flipping and docking. Then, the two main structural frames 1 are flipped towards each other by the two flipping mechanisms 3. Specifically, the first telescopic drive device 33 drives the main structural frame 1 to rotate along the first support 31, causing the two main structural frames 1 to flip towards each other until the two members 100 to be spliced ​​come into contact with each other and fall onto the inner support bracket 4. The inner support bracket 4 can ensure the stable support of the two members 100 to be spliced. Then, the connection parts of the two members 100 to be spliced ​​are assembled by welding. After welding is completed, the fixing of the member 100 to be spliced ​​on one of the main structural frames 1 is released. Then, the two main structural frames 1 are unfolded away from each other by the two flipping mechanisms 3. Finally, temporary lifting lugs are installed on the spliced ​​members, or other lifting devices are used to lift the members out. Compared to existing technologies, the rod splicing device of this invention offers several advantages. First, the rotation and turning of the rods are controlled by a telescopic drive device, which is easier and more accurate than using a crane, manual labor, and hinges for rotation and turning.
