Description

Technical Field

[0001] This utility model relates to a pipe fitting positioning auxiliary clamp, specifically a fire protection engineering pipe fitting positioning auxiliary clamp, belonging to the field of fire protection engineering technology. Background Technology

[0002] In fire protection engineering, pipe fittings are key components of fire water supply systems and fire extinguishing systems, used to transport fire water and fire extinguishing media.

[0003] In the prior art, an auxiliary tooling for fire water pipe installation, authorized by announcement number CN216229078U, includes a base plate. The top of the base plate has a first sliding groove. A first dual-axis motor is welded and installed on the bottom inner side of the first sliding groove. The output end of the first dual-axis motor is welded and installed with a first threaded rod through a coupling. The free end of the first threaded rod is rotatably connected to the inner walls of both sides of the first sliding groove in sequence. The first sliding groove has a built-in first slider.

[0004] While the existing device can fix two pipe fittings, when using it for butt welding of two L-shaped elbows, due to the special structure of the L-shaped elbows, the fixed L-shaped elbows may need to be fine-tuned to ensure that the two L-shaped elbows are in the same position. However, the existing device cannot meet the adjustment requirements. Therefore, workers often need to disassemble the fixed L-shaped elbows, adjust them, and then re-fix them. This process is cumbersome, not only wasting a lot of manpower and time, but also reducing the practicality of the device. Utility Model Content

[0017] This utility model provides a positioning auxiliary clamp for fire protection engineering pipe fittings.

[0018] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The system includes a workbench 1, with support frames 2 on both sides of the top of the workbench 1. One support frame 2 is fixedly connected to the workbench 1, and the other support frame 2 has a lifting structure and a pushing structure at its bottom. An arc-shaped toothed plate 7 is provided inside the support frame 2, and a limiting structure is provided between the arc-shaped toothed plate 7 and the support frame 2. The limiting structure includes two arc-shaped grooves 200, which are respectively formed on both sides of the inside of the support frame 2. Arc-shaped grooves 201 are formed on the inner sides of the two arc-shaped grooves 200. Inside the 200, there are two sliding arc-shaped slide rods 8. Both arc-shaped slide rods 8 are fixedly connected to the arc-shaped toothed plate 7. The inner side of the arc-shaped toothed plate 7 is provided with a clamping structure. The bottom of the arc-shaped toothed plate 7 is meshed with a gear 12. The inner side of the gear 12 is fixedly connected with a rotating shaft 9. Both ends of the rotating shaft 9 are rotatably connected to the support frame 2. The outer side of the rotating shaft 9 is fixedly connected with a worm gear 10. The outer side of the worm gear 10 is meshed with a worm 11. Both ends of the worm 11 pass through the inner side of the support frame 2 and are rotatably connected to the support frame 2. A handwheel is installed at one end of the worm 11.

[0019] The clamping structure includes a clamp 13, which is located inside the arc-shaped toothed plate 7. Two connecting posts 14 are fixedly connected to both sides of the clamp 13. One end of each of the connecting posts 14 is fixedly connected to the arc-shaped toothed plate 7. A clamp 2 15 is provided on the top of the clamp 13. The clamp 2 15 is adapted to the clamp 13. The clamping structure also includes a hydraulic cylinder 3 16, which is fixedly connected to the top of the clamp 2 15. A T-shaped plate 17 is fixedly connected to the outside of the hydraulic cylinder 3 16. L-shaped support rods 18 are fixedly connected to both sides of the bottom of the T-shaped plate 17. One end of each of the two L-shaped support rods 18 passes through two arc-shaped grooves 201 and is fixedly connected to two arc-shaped sliding rods 8.

[0020] Specifically, after placing the L-shaped elbow pipe in the designated position of clamp 13, hydraulic cylinder 3 16 is activated. The telescopic end of hydraulic cylinder 3 16 pushes clamp 2 15 downward, so that it works in conjunction with clamp 13 to clamp the L-shaped elbow pipe. This operation ensures that one end of one L-shaped elbow pipe faces upward and the other end faces downward. Clamp 13 and clamp 2 15 are equipped with anti-slip pads, which can improve the stability of fixing the pipe fittings.

[0021] When the ends of two L-shaped elbows to be welded are misaligned, the operator can turn the handwheel. The handwheel drives the worm gear 11 to rotate, which in turn drives the worm wheel 10 to rotate. The worm wheel 10 drives the gear 12 to rotate via the shaft 9. The gear 12 meshes with the arc-shaped toothed plate 7, thereby driving the arc-shaped toothed plate 7 to rotate. The arc-shaped toothed plate 7 drives the arc-shaped sliding rods 8 fixedly connected to its two sides to slide in the two arc-shaped grooves 200 respectively. At the same time, the two arc-shaped sliding rods 8 drive the two L-shaped support rods 18 fixed to them to move synchronously in the two arc-shaped grooves 201. Through this structure, the fixed L-shaped elbows can be rotated and finely adjusted, so that the ends of the two L-shaped elbows to be welded can be quickly and accurately aligned, effectively improving the practicality of the device.

[0022] Example 2, please refer to Figure 1 and Figure 2 The lifting structure includes two hydraulic cylinders 6, both of which are fixedly connected to the bottom of another support frame 2. The two hydraulic cylinders 6 are symmetrically distributed with respect to the vertical center line of the support frame 2.

[0023] The pushing structure includes a cross groove 100, which is opened on the top of the worktable 1. A cross seat 3 is slidably arranged inside the cross groove 100. Two mounting vertical slots 5 are opened on the top of the cross seat 3. Two hydraulic cylinders 6 are respectively arranged inside the two mounting vertical slots 5 and fixedly connected to the cross seat 3. A hydraulic cylinder 4 is fixedly connected to one side of the cross seat 3. The hydraulic cylinder 4 passes through the inside of the cross groove 100 and extends to one side of the worktable 1. The hydraulic cylinder 4 is fixedly connected to the worktable 1.

[0024] Specifically, when one end of the two L-shaped elbows is aligned, the two hydraulic cylinders 6 are activated. The telescopic ends of the two hydraulic cylinders 6 drive the other support frame 2 to move downward, so that the L-shaped elbow fixed on the other support frame 2 can be connected with the L-shaped elbow fixed on one of the support frames 2. In addition, hydraulic cylinder 4 is activated, which drives the cross seat 3 to slide inside the cross groove 100. Through two hydraulic cylinders 6, the other support frame 2 is moved, thereby moving and adjusting the L-shaped elbow on the other support frame 2 so that it is aligned with the L-shaped elbow on one of the support frames 2.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
