Description
Technical Field
[0001] This utility model relates to the field of pipe laying and transportation technology in pipe gallery, and in particular to a pipe laying device. Background Technology
[0002] Against the backdrop of rapid development in the chemical industry, the production scale of chemical plants continues to expand. As a crucial infrastructure for transporting various media, pipe racks are increasingly carrying a growing number and diameter of pipelines. Especially during the expansion and efficiency improvement or technological upgrading of existing chemical plants, a large number of new pipelines need to be added to the existing pipe racks to meet the demands of upgraded production processes. The internal space of pipe racks is long and narrow, with a complex environment. The transportation and installation of pipelines within these racks directly impacts the progress, efficiency, and construction safety of the entire pipeline installation project, making it a critical step in the pipe rack installation process. Currently, pipeline transportation within utility tunnels primarily relies on pipe threading devices. Traditional pipe threading devices mostly employ a straight roller structure, with the rollers arranged in a straight line and maintained horizontally. However, in practical applications, this type of straight roller pipe threading device has several limitations: Firstly, the straight roller structure provides poor pipe positioning; during pipeline transport, the pipe is prone to slipping off the rollers due to a shift in the center of gravity, affecting transportation efficiency and potentially causing pipe impacts, damage, or even safety accidents. Secondly, the rollers of straight roller pipe threading devices are usually integrally connected or designed in a large-scale modular fashion. When individual rollers are damaged, the entire device needs to be replaced, which undoubtedly increases maintenance costs and leads to material waste. Therefore, there is an urgent need for a pipe threader that can limit the movement of pipes, improve the stability of pipe transportation, ensure transportation safety, and reduce maintenance costs. Utility Model Content
[0003] The purpose of this utility model is to provide a pipe threading device that can limit the movement of pipes during transportation, improve the stability of pipe transportation, and ensure transportation safety. At the same time, the spaced arrangement of multiple rollers facilitates targeted replacement and maintenance, reduces maintenance costs and material consumption, and is highly practical.
[0004] The present invention adopts the following technical solution: A pipe threading device includes a base, on which rollers are rotatably mounted. The rollers are spaced apart along the length of the base, and the rollers at both ends of the base are arranged at an angle, forming a concave structure with higher ends and a lower middle section between the rollers at both ends and the roller in the middle.
[0005] Preferably, the base is provided with multiple sets of mounting plates, and each roller is rotatably disposed between two mounting plates in each set.
[0006] Preferably, the roller is rotatably mounted on a support shaft, and both ends of the support shaft are connected to the corresponding mounting plates.
[0007] Preferably, both ends of the support shaft are provided with positioning plates, and the end faces of the positioning plates that connect with the mounting plates are provided with mutually meshing positioning teeth and positioning grooves, wherein one end of the positioning plate is movably connected to the support shaft; the mounting plate is provided with a mounting groove that penetrates its top.
[0008] Preferably, the positioning plate is movably connected to the support shaft in an elastic connection.
[0009] Preferably, one end of the support shaft is provided with a receiving hole, and a support rod is connected to the receiving hole by a spring. The end of the support rod is provided with the positioning plate.
[0010] Preferably, the end section of the support rod is a non-circular structure, and the shape of the receiving hole matches the shape of the support rod.
[0011] Preferably, the base includes a base plate, the rollers are disposed on the base plate, and fixing plates are vertically disposed at both ends of the base plate, with fixing holes provided on the fixing plates. Preferably, the fixing hole is rectangular.
[0012] Compared with the prior art, the beneficial effects of this invention are as follows: This utility model, through the inclined arrangement of rollers at both ends to form a concave structure with "high at both ends and low in the middle," can provide a stable limiting effect on the pipeline. During the transportation process, the pipeline naturally falls into the concave area, effectively preventing large-diameter pipelines from slipping due to the shift in the center of gravity, reducing the risk of pipeline collisions and damage, ensuring construction safety, and avoiding delays in the construction period caused by pipeline slippage.
[0013] This invention arranges rollers at intervals along the length of the base. When individual rollers wear out or become damaged due to long-term use, the damaged rollers can be replaced individually without replacing the entire pipe threading device. This significantly reduces the cost of spare parts and labor required for maintenance, while also reducing material waste and extending the overall service life of the equipment.

Detailed Implementation
[0015] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments: like Figures 1 to 4 As shown, the cement grinding grate of this utility model includes a base 1, on which rollers 2 are rotatably mounted. The rollers 2 are preferably made of nylon, which is lightweight, wear-resistant, and has a strong load-bearing capacity. Multiple rollers 2 are spaced apart along the length of the base 1, with the rollers at both ends of the base 1 arranged at an angle. The rollers at both ends and the roller in the middle form a concave structure with higher ends and a lower middle, which provides stable restraint for the pipeline. This allows the pipeline to naturally fall into the concave area during transport, effectively preventing large-diameter pipelines from slipping due to a shift in the center of gravity, reducing the risk of pipeline collisions and damage, ensuring construction safety, and avoiding delays caused by pipeline slippage. Furthermore, in this utility model, the spaced rollers 2 serve as supports for pipeline transport, facilitating subsequent targeted replacement of worn or damaged rollers 2 without requiring a complete replacement of the pipe threading device. This significantly reduces the cost of spare parts and labor required for maintenance, while also reducing material waste and extending the overall service life of the equipment. The tube threading device of this application mainly consists of a base 1 and multiple rollers 2 spaced apart. It has no complex transmission components or auxiliary structures, and the overall structure is simple. The number of parts is greatly reduced, which significantly reduces the input of raw materials and the difficulty of processing, thereby reducing the manufacturing cost.
[0016] Furthermore, in this embodiment, the base 1 includes a base plate 1-1, rollers 2 are mounted on the base plate 1-1, and fixing plates 1-2 are vertically mounted at both ends of the base plate 1-1. Fixing holes are provided on the fixing plates 1-2, preferably rectangular, to allow the base 1 to adapt to various steel structure beams of different sizes, greatly reducing reliance on specific specifications of steel structure beams. This significantly expands the applicability of the base 1 and enhances the versatility and practicality of the pipe threading device in different pipe gallery environments. The base 1 can be connected to the steel structure beam using fixing bolts inserted into the fixing holes.
[0017] Furthermore, the base 1 is provided with multiple sets of mounting plates 3, and each roller 2 is rotatably positioned between two mounting plates 3 in each set. The roller 2 is rotatably mounted on a support shaft 4 via bearings, and both ends of the support shaft 4 are connected to the corresponding mounting plates 3. Preferably, both ends of the support shaft 4 are provided with positioning plates 5, and the end faces of the positioning plates 5 where they meet the mounting plates 3 are provided with meshing positioning teeth and positioning grooves. One end of the positioning plate 5 is movably connected to the support shaft 4, and the mounting plate 3 is provided with a mounting groove 6 extending through its top. The design of the mounting groove 6 at the top of the mounting plate 3 allows both ends of the support shaft 4 to be directly inserted into the installation position from the top, without the need for precise alignment and insertion. During installation, simply place the support shaft 4 in the mounting groove 6, and adjust the positioning plate 5 movably connected at one end to ensure that both ends of the positioning plates 5 are engaged with the mounting plate 3, thus achieving rapid fixing of the roller 2. The entire process does not require professional technicians; ordinary construction workers can complete it after simple training, simplifying the construction process, reducing reliance on operational skills, and thus reducing labor costs.
[0018] Preferably, the movably connected positioning plate 5 is elastically connected to the support shaft 4. Specifically, one end of the support shaft 4 has a receiving hole 7, and a support rod 9 is connected to the receiving hole 7 via a spring 8. The end of the support rod 9 is provided with the positioning plate 5. Under normal working conditions, the spring 8 is in a stretched state; during operation, the elastic force of the spring 8 pushes the support rod 9, causing the positioning plate 5 to tightly engage with the mounting plate 3, ensuring that the positioning teeth and positioning grooves are firmly engaged, effectively preventing positioning loosening due to vibration and other factors, and ensuring the stability of the roller 2 during the transportation pipeline process. When it is necessary to disassemble the roller 2, the operator only needs to pull the elastically set positioning plate 5 towards the support shaft 4 to disengage the positioning plate 5 from the mounting plate 3. The positioning plate 5 will then easily disengage from the corresponding end mounting plate 3 without the need for additional tools, making the operation labor-saving and convenient. Compared to traditional rigid connections or methods requiring manual loosening of fasteners, this design significantly reduces the difficulty and intensity of disassembly, especially in space-constrained environments such as pipe racks. It allows operators to disassemble roller 2 more quickly and efficiently, significantly improving maintenance and replacement efficiency and further demonstrating its simple structure and convenient operation. Meanwhile, the elastic return function of spring 8 ensures ease of installation. After roller 2 is installed and positioned, releasing the positioning plate 5 automatically pushes the support rod 9 and positioning plate 5 back to their original positions, re-engaging them with the mounting plate 3. This eliminates the need for manual precise alignment of the positioning plate 5, simplifying the installation process and ensuring a smooth and efficient workflow.
[0019] Furthermore, in this embodiment, the end section of the support rod 9 is a non-circular structure, preferably a square or hexagonal structure, and the shape of the receiving hole 7 matches the shape of the support rod 9. With this configuration, when the roller 2 rotates during pipeline transport, the support shaft 4 will be subjected to frictional force and torque from the pipeline. If the support rod 9 and the receiving hole 7 are circularly fitted, they are prone to relative rotation due to force. However, the non-circular structure (such as square or hexagonal) fit can form a circumferential limit through the mutual contact of the contour surfaces, effectively preventing relative rotation between the support shaft 4 and the support rod 9. This limiting effect ensures that the torque transmitted by the support shaft 4 can stably act on the support rod 9 and the positioning plate 5, avoiding misalignment or loosening of the positioning teeth and positioning grooves of the positioning plate 5 and the mounting plate 3 due to relative rotation. This ensures the installation stability of the roller 2 during rotation, reduces component wear caused by structural sway, and extends the service life of the equipment.
[0020] In use, the pipe threader is horizontally mounted on the crossbeam of the pipe gallery via bolts from the base 1. For long pipe galleries, multiple threaders can be fixed in rows on the crossbeam. The pipe is placed on the threader and pushed forward with slight force. The pipe is positioned on the centrally located horizontal roller 2, limited by the rollers 2 on both sides, effectively preventing it from slipping due to a shift in the center of gravity during transport. This reduces the risk of pipe impact and damage, ensuring construction safety and avoiding delays caused by pipe slippage, thus ensuring work efficiency. Furthermore, the separate design of the multiple rollers 2 facilitates subsequent targeted replacement and maintenance, significantly reducing the cost of spare parts and labor, minimizing material waste, and extending the overall service life of the equipment.
