Description

Technical Field

[0001] The utility model relates to the technical field of pipe gallery pipeline construction, in particular to a pipe gallery pipe threader. Background Art

[0002] With the development of the national economy, the scale of project construction in various industries such as petroleum, chemical industry, and metallurgy is increasing. The design of pipeline corridors for the entire plant and equipment areas is getting higher and higher, and the pipeline layout in the pipeline corridor is becoming more and more dense. In addition, the high height and long distance of the pipeline corridor make it very difficult to hoist and place the pipeline in the pipeline corridor. Traditional pipe threading methods such as direct pipe threading by crane, pipe threading with chain pull, steel roller pipe threader, and rail trolley pipe threading can no longer meet the needs of low cost, safety, quality, progress, and work progress protection.

[0003] In the prior art, pipe gallery pipe threaders are often used for pipe threading. By installing the pipe gallery pipe threader at a preset installation position and using the rollers on the pipe gallery pipe threader to transport the pipe, the process is simple, fast, low-cost, and has low safety risks. However, the existing pipe gallery pipe threader is usually implemented by mounting rollers on two supporting devices. The two supporting members are independent of each other, resulting in poor stability of the entire pipe gallery pipe threader and prone to unstable installation, which leads to unnecessary risks in the pipeline transportation process. Utility Model Content

[0004] The utility model provides a pipe gallery pipe penetrator to solve the problem in the prior art that two supporting members of the pipe gallery pipe penetrator are independent of each other, resulting in poor stability of the entire pipe gallery pipe penetrator.

[0005] To achieve the above purpose, the present invention provides the following solutions:

[0006] A pipe gallery pipe threader includes a roller, a bearing installed in the roller, support members installed at both ends of the bearing and a mounting plate installed on the support members. A recessed portion is provided on the surface of the roller, and the roller is made of polyamide material.

[0007] The utility model makes the roller of polyamide material, so that it has excellent mechanical properties, strong heat resistance, high toughness, and is not easily fractured by the pipeline. When subjected to greater pressure, the concave portion of the roller can fit the pipeline under deformation to provide greater friction.

[0008] Furthermore, two groups of connecting parts are provided between the two mounting plates.

[0009] By setting two sets of connecting parts between the two mounting plates, there are multiple connections between the two mounting plates. When one of the mounting plates becomes loose, the other mounting plate can provide connection and fixation for it, thereby improving the stability of the pipe gallery pipe threader and reducing safety risks.

[0010] Furthermore, the connecting member includes a connecting plate fixedly connected to the mounting plate, the two corresponding connecting plates match each other, and a fastener is provided between the two corresponding connecting plates.

[0011] The length of the connecting piece can be changed by the connecting plate and the fastener, so that it can adapt to rollers of more sizes and has a wider range of adaptability.

[0012] Furthermore, the fastening member includes a limit housing and a gear rotatably connected to the limit housing, and racks are provided on opposite sides of the two corresponding connecting plates, and the racks match the gears. The two connecting plates are driven closer or farther apart by rotating the gears, which is easy to operate.

[0013] Furthermore, the fastening member further includes a fastening nut, and the rotating shaft of the gear passes through the limiting housing and is connected to the fastening nut. The fastening nut fixes the gear and prevents the gear from rotating again when the length of the connecting member is adjusted to the required length, thereby affecting the stability of the device.

[0014] Furthermore, two opposite side walls of the position limiting housing are provided with through holes, and the two connecting plates pass through the two through holes. The two connecting plates can move in the two through holes, thereby increasing the adjustable length of the connecting piece.

[0015] Furthermore, the outer side walls of the two connecting plates are both fitted with the side walls of the through hole. The two connecting plates are limited by the side walls on both sides of the through hole so that the connecting plates are closely attached to the gears to prevent slipping when the gears are rotated.

[0016] Furthermore, a handle is provided on the rotating shaft of the gear, so that the gear can be controlled to rotate by hand, which is convenient for manual operation of the device.

[0017] Furthermore, the roller is a U-shaped roller, and the specific curvature is designed according to the maximum pipe diameter, which can better wrap the pipe and provide good support, making it less likely to deviate.

[0018] Furthermore, the mounting plate is provided with a plurality of screw holes, and the length of the screw holes is greater than the diameter of the screw holes.

[0019] One or more technical solutions provided by this utility model have at least the following technical effects or advantages:

[0020] (1) The utility model makes the roller of polyamide material, which has excellent mechanical properties, strong heat resistance, high toughness, and is not easily fractured by the pipeline. When subjected to greater pressure, the U-shaped roller can fit the pipeline under deformation and provide greater friction;

[0021] (2) By setting two sets of connecting pieces between the two mounting plates, there are multiple connections between the two mounting plates. When one of the mounting plates becomes loose, the other mounting plate can provide connection and fixation for it, thereby improving the stability of the pipe gallery pipe threader and reducing safety risks;

[0022] (3) By rotating the gears to drive the two connecting plates closer or farther away, the length of the connecting parts can be changed, which can adapt to rollers of more sizes, has a wider range of adaptability, and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
