Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to an auxiliary support device for welding MPP pipes. Background Technology

[0002] MPP pipes use modified polypropylene as the main raw material, allowing for the laying of pipelines and cables in special locations such as roads, railways, buildings, and riverbeds without extensive dredging, excavation, or road surface damage. Compared to the traditional trenching method, trenchless power conduit engineering is more in line with current environmental protection requirements, eliminating the dust, traffic congestion, and other disturbances caused by traditional construction. This technology can also be used to lay pipelines in areas where excavation is not feasible, such as historical sites, urban areas, crop and farmland protection zones, highways, and rivers.

[0003] MPP pipe welding is usually carried out by hot fusion. In actual use, when welding two MPP pipes, due to the excessive length of the pipes, manual or other flat objects are usually required for auxiliary support to prevent the pipes from bending and being damaged. However, the existing equipment cannot provide auxiliary support according to the diameter and height of the pipes, which reduces the work efficiency to a certain extent. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the background art by proposing an auxiliary support device for MPP pipe welding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An auxiliary support device for welding MPP pipes includes a mounting base. The upper surface of the mounting base has two symmetrically arranged sliding grooves. The upper surface of the mounting base also has a drive groove and a transmission groove, which are connected. A motor is installed in the drive groove, and the output shaft of the motor extends into the transmission groove. A double-threaded rod is connected to the inner wall of the transmission groove via bearings, and the output shaft of the motor is fixedly connected to one end of the double-threaded rod. The double-threaded rod is threadedly connected to two sliders, each slider being slidably engaged within the transmission groove. Each slider has a fixing mechanism on its upper surface, and the output end of the fixing mechanism is engaged within a corresponding sliding groove. Two symmetrically arranged storage slots are opened on both sides of the mounting base, and a support mechanism is connected between the two storage slots on the same side of the mounting base.

[0007] Preferably, each of the fixing mechanisms includes two mounting plates, and each mounting plate is slidably engaged in a corresponding groove. Each mounting plate has a protective groove, and a protective roller is installed in each protective groove via a rotating shaft. A connecting plate is fixedly installed on one side of each mounting plate, and one end of each connecting plate is fixedly connected to the slider.

[0008] Preferably, each of the connecting plates has a plurality of first rotating rollers rotatably mounted on its end face.

[0009] Preferably, each of the support mechanisms includes a mounting frame, and the output end of each mounting frame is slidably locked in the storage groove. The upper end face of the mounting frame is provided with a threaded groove, and a threaded rod is threadedly connected to the threaded groove. A fixing block is fixedly installed at one end of the threaded rod, and a placement frame is fixedly installed on both sides of the fixing block.

[0010] Preferably, each of the placement racks has a plurality of second rotating rollers rotatably mounted on its end face.

[0011] Preferably, each of the mounting brackets has multiple rollers on its lower end face.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. By setting up a fixing mechanism, a motor, a double-ended threaded rod, and a slider, different sized pipes can be placed on the fixing mechanism. The motor and double-ended threaded rod can drive the pipes on the fixing mechanism to move closer together, which is more conducive to welding.

[0014] 2. By setting up a support mechanism, the length of the pipe can be adjusted and assisted in the support. At the same time, the support mechanism can lift pipes of different diameters in a synchronized manner, making it suitable for pipes of different sizes.

[0015] In summary, this utility model, by setting up a fixing mechanism and a support mechanism, can fix and support pipes of different sizes. At the same time, it can provide auxiliary support for the pipes according to their length, eliminating the need for manual auxiliary support and improving work efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 The MPP pipe welding auxiliary support device includes a mounting base 1. The upper end face of the mounting base 1 is symmetrically provided with two sliding grooves 2. The upper end face of the mounting base 1 is provided with a drive groove 4 and a transmission groove, and the transmission groove is connected to the drive groove 4. A motor 3 is provided in the drive groove 4, and the output shaft of the motor 3 extends into the transmission groove. A double-threaded rod 8 is connected to the inner side wall of the transmission groove through a bearing, and the output shaft of the motor 3 is fixedly connected to one end of the double-threaded rod 8. The double-threaded rod 8 is threadedly connected to two sliders 6, and each slider 6 is slidably locked in the transmission groove. It should be noted that the two sliders 6 are respectively threadedly connected to the two threads of the double-threaded rod 8.

[0022] Each slider 6 has a fixing mechanism on its upper surface, and the output end of the fixing mechanism is respectively locked in the corresponding slide groove 2. Two storage slots 17 are symmetrically opened on both sides of the mounting base 1, and a support mechanism is connected between the two storage slots 17 on the same side of the mounting base 1.

[0023] Each fixing mechanism includes two mounting plates 5, and each mounting plate 5 is slidably locked in the corresponding groove 2. Each mounting plate 5 has a protective groove 11, and each protective groove 11 is equipped with a protective roller 10 through a rotating shaft. It should be noted that the protective roller 10 can protect the maximum outer wall of the pipe.

[0024] Each mounting plate 5 has a connecting plate 7 fixedly installed on one side, and one end of each connecting plate 7 is fixedly connected to the slider 6. Each end face of the connecting plate 7 is rotatably fitted with multiple first rotating rollers 9. It should be noted that when the pipe rotates, the multiple first rotating rollers 9 can rotate synchronously with the pipe.

[0025] Each support mechanism includes a mounting frame 12, and the output end of each mounting frame 12 is slidably locked in the storage slot 17. The lower end face of each mounting frame 12 is provided with multiple rollers. The upper end face of the mounting frame 12 is provided with a threaded groove, and a threaded rod 13 is threadedly connected to the threaded groove. A fixing block 14 is fixedly installed at one end of each threaded rod 13. Placement frames 15 are fixedly installed on both sides of the fixing block 14. Multiple second rotating rollers 16 are rotatably locked on the end face of each placement frame 15.

[0026] When using this utility model, firstly, according to the actual length of the pipe, the mounting bracket 12 in the storage groove 17 is pulled out. Then, according to the required size and diameter of the pipe to be welded, the threaded rod 13 is turned. The threaded rod 13 is then screwed out from the threaded groove. At this time, the fixing block 14 drives the placement brackets 15 on both sides to rise until they are raised to a height that matches the diameter of the pipe.

[0027] The pipe can then be placed on the fixing mechanism. At this time, the motor 3 can be driven. The output shaft of the motor 3 drives the double-threaded rod 8 to rotate. At this time, the slider 6, which is threaded on the double-threaded rod 8, will move in the transmission groove along with the rotation of the double-threaded rod 8. The displacement of the slider 6 will drive the connecting plate 7 to move. The mounting plate 5 will move synchronously in the slide groove 2 through the movement of the connecting plate 7. At this time, the two fixing devices will move closer to each other.

[0028] When the pipe needs to be rotated, the first rotating roller 9 on the mounting plate 5 will rotate synchronously with the rotation of the pipe, and at the same time, the second rotating roller 16 on the placement frame 15 will rotate synchronously with the rotation of the pipe, saving some of the force required to rotate the pipe.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
