Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for pipe connection, specifically a water supply pipe connection support device. Background Technology

[0002] During the construction of urban water supply pipelines, it is often necessary to connect the ends of two pipes. Especially when pipe welding is involved, the end of one pipe needs to be aligned and fixed with the end of the other pipe in order to continue the welding work. The existing alignment method is mostly to place a rotating block or other support on the underside of the pipe end. After welding, the block can be removed. However, since the height difference between the ends of the two pipes to be connected is uncertain, this method has a great limitation in aligning the ends of the two pipes. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a water supply pipeline connection support device.

[0004] The technical solution of this utility model is as follows:

[0005] A water supply pipeline connection support device is used for supporting and fixing the ends of two pipelines to be connected. The support device (the above-mentioned water supply pipeline connection support device) includes a clamping frame that can be clamped and fixed at the end of one of the pipelines. A hinge seat is provided on one side of the clamping frame, and a lifting mechanism that can lift and fix the end of the other pipeline is hinged through the hinge seat. During the connection construction, the clamping frame can be clamped on the end of the pipeline that has been fixed. The lifting mechanism can lift and fix the end of the other pipeline to be connected so as to complete the subsequent connection work.

[0006] As the core technical concept of this utility model, the clamping frame includes a vertically arranged central rod with two parallel clamping rods at its upper and lower ends. The hinge seat is arranged on the upper clamping rod. This arrangement allows the clamping frame to be easily inserted into one side of the pipe end, and after connection, the clamping frame can be easily removed from the pipe. The hoisting mechanism includes an L-shaped lifting rod whose plane is perpendicular to the plane of the clamping frame. One end of the lifting rod is hinged to the hinge seat, and the other end is vertically provided with an adjusting screw. The lower end of the adjusting screw is rotatably provided with a hook, and a lifting rope that can be fitted onto the outer ring of the pipe is provided through the hook. By rotating the adjusting screw, the end of the pipe to be connected can be moved up and down, thereby easily aligning the ends of the two pipes. At the same time, even if the distance between the two clamping rods is greater than the diameter of the pipe, the clamping frame can still be stably clamped onto the pipe due to the downward pressure on one end of the lifting rod, which significantly improves the connection efficiency of the pipe.

[0007] As described above, a water supply pipeline connection support device includes a hinged seat, a hanger rod including a vertically arranged connecting rod with its lower end hinged to the seat, a support rod on the upper front side of the connecting rod, and an adjusting screw vertically disposed at the end of the support rod. In a preferred embodiment, to adapt to the connection work of pipelines with different diameters and to ensure that the hanger rod can still complete the lifting and fixing work of the pipeline normally when the pipe diameter changes, a limiting bolt that can abut against the front side of the connecting rod is provided on the upper front side of the seat.

[0008] As a further preferred embodiment, in order to ensure the hinge connection strength between the pad rod and the hinge seat, and thus ensure its stability during hoisting, a hinge notch is provided on the upper rear side of the seat body, and the lower end of the connecting rod is hinged to the hinge notch.

[0009] As described above, in a preferred embodiment of the water supply pipeline connection support device, to facilitate the adjustment of the height of the end of the pipeline to be connected by adjusting the screw, i.e. to facilitate the rotation of the adjusting screw, the end of the adjusting screw away from the hook has a T-shaped structure.

[0010] As a further preferred embodiment, to facilitate the assembly and disassembly of the lifting rope, the hook has an anchor-like structure, with both ends of the lifting rope respectively attached to both sides of the hook.

[0011] Preferably, to ensure the clamping and fixing effect of the clamping frame relative to the pipe, the middle rod has a semi-circular arc structure and forms a gantry frame shape with the two clamping rods.

[0012] As described above, in a preferred embodiment of the water supply pipeline connection support device, both the frame and the hanger are made of steel to ensure the support stability of the support device.

[0013] As a further preferred embodiment, to further ensure the stability of the pipe hoisting effect by the suspender rod and to ensure the structural strength of the fishing rod, a reinforcing rib is also provided between the connecting rod and the support rod.

[0014] The beneficial effects of this utility model are as follows: This utility model is a water supply pipe connection support device. The clamping frame can be easily inserted from one side of the pipe end, and after the connection is completed, the clamping frame can be easily removed from the pipe. By rotating the adjusting screw, the end of the pipe to be connected can be moved up and down, so that the ends of the two pipes can be easily aligned. At the same time, even if the distance between the two clamping rods is greater than the diameter of the pipe, the clamping frame can still be stably clamped on the pipe due to the downward pressure on one end of the hanging rod, which significantly improves the connection efficiency of the pipe.

[0022] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0023] Example

[0024] This embodiment provides a water supply pipeline connection support device for supporting and fixing two pipelines 1 to be connected at their ends. See [link / reference]. Figure 1 and Figure 2 The support device 2 includes a clamping frame 21 that can be clamped and fixed at the docking end of one of the pipes 1. The clamping frame 21 has a hinge seat 22 on one side, and a lifting mechanism 23 that can lift and fix the docking end of the other pipe 1 is hinged to the hinge seat 22. During docking construction, the clamping frame 21 can be clamped at the end of the pipe 1 that has been fixed. The lifting mechanism 23 can lift and fix the end of the other pipe 1 to be docked, so as to complete the subsequent docking connection (e.g., welding connection) work. The structure of the support device 2 will be described in detail below.

[0025] In this embodiment, as one of the core technical concepts of this utility model, the card frame 21 includes a vertically arranged middle rod, with two card rods arranged parallel to each other at its upper and lower ends. The hinge seat 22 is arranged on the upper card rod. With this arrangement, the card frame 21 can be easily inserted into one side of the end of the pipe 1. At the same time, after the connection is completed, the card frame 21 can also be easily removed from the pipe 1.

[0026] Specifically, the clamping rods are arranged in the left-right direction, and the middle rod is connected to the left or right side of the two clamping rods. The two clamping rods have openings on the side opposite to the middle rod so that the clamping frame 21 can be smoothly inserted from the side of the pipe 1. As a preferred embodiment, in order to ensure the clamping and fixing effect of the clamping frame 21 relative to the pipe 1, the middle rod is a semi-circular arc structure that protrudes outward, and forms a gantry frame shape with the two clamping rods.

[0027] In this embodiment, as another core technical concept of the present invention, the hoisting mechanism 23 includes an L-shaped hoisting rod 231 whose plane is perpendicular to the plane of the clamping frame 21. One end of the hoisting rod 231 is hinged to the hinge seat 22, and the other end is provided with an adjusting screw 232 vertically. The lower end of the adjusting screw 232 is provided with a hook, and a hoisting rope 234 that can be sleeved on the outer ring of the pipe 1 is provided through the hook. By rotating the adjusting screw 232, the end of the pipe 1 to be connected can be moved up and down, so that the ends of the two pipes 1 can be easily aligned. At the same time, even if the distance between the two clamping rods is greater than the diameter of the pipe 1, the clamping frame 21 can still be stably clamped on the pipe 1 due to the downward pressure on one end of the hoisting rod 231, which significantly improves the connection efficiency of the pipe 1.

[0028] Combination Figure 3 Specifically, the hinge seat 22 includes a seat body 221 located at the connection position between the upper support rod and the middle rod, and the hanging rod 231 includes a connecting rod that is vertically arranged and hinged to the seat body 221 at its lower end. The rotation plane of the connecting rod is perpendicular to the plane of the frame 21, and a support rod is provided laterally on the front side of the upper end of the connecting rod facing the front side of the support device 2. The adjusting screw 232 is vertically arranged at the end of the support rod.

[0029] In a preferred embodiment, to ensure the hinge connection strength between the pad rod and the hinge seat 22, and thus ensure its stability during hoisting, the upper rear side of the seat 221 is provided with a hinge notch, and the lower end of the connecting rod is hinged to the hinge notch.

[0030] As a further preferred embodiment, to facilitate the adjustment of the height of the end of the pipe to be connected 1 by adjusting the screw 232, i.e. to facilitate the rotation of the screw 232, the adjusting screw 232 is positioned away from the hook end, i.e., the upper end of the adjusting screw 232 has a T-shaped structure.

[0031] Preferably, to facilitate the assembly and disassembly of the lifting rope 234, the hook adopts an anchor-shaped structure, and the two ends of the lifting rope 234 are respectively hung on both sides of the hook.

[0032] In this embodiment, as a preferred implementation, in order to adapt to the connection work of pipes 1 with different pipe diameters and to ensure that the lifting rod 231 can still complete the lifting and fixing work of pipe 1 normally when the pipe diameter changes, the upper front side of the seat 221 is also provided with a limiting bolt 222 that can abut against the front side of the middle of the connecting rod.

[0033] As a further preferred embodiment, to ensure the support stability of the support device 2, both the frame 21 and the hanger rod 231 are made of steel.

[0034] Preferably, to further ensure the stability of the lifting effect of the pipe 1 by the lifting rod 231 and to ensure the structural strength of the fishing rod, a reinforcing rib (not shown in the figure) is also provided between the connecting rod and the support rod. It should be noted that the lifting rod 231 of this utility model should be controlled to adapt to the weight of the pipe 1. For example, the design of the lifting rod 231 can be thickened to ensure that it can be used for lifting the pipe 1 with a large weight.
