Description

Technical Field

[0001] The present invention relates to the field of pipeline installation, and in particular to an automated pipeline threading and conveying device for a pipeline gallery and the same. Background Art

[0002] With the development of large-scale petrochemical plants, pipe corridors are an indispensable part of petrochemical plants. The pipes in the pipe corridors are compactly laid out, with different floor heights, pipe diameters ranging from small to large, and various materials covering the pipe corridors. Various pipe-threading devices are common. How to quickly and safely install the pipes in the pipe corridors? The traditional approach is to use pipe-threading devices to thread pipes, directly hoisting steel pipe sections from both sides of the pipe corridor into the steel structure, and then workers move the steel pipes to the desired position by manpower or with the help of simple tools. Although this approach has certain advantages when installing large pipe fittings and special-shaped pipelines, the solution is complex to operate, has low efficiency, and requires frequent changes in the position of the crane. Summary of the invention

[0003] In view of the defects or shortcomings in the prior art, the present invention provides an automatic pipeline pipe threading and conveying device for a pipe gallery, which can meet the needs of the assembly and welding of steel pipes of different sizes and specifications. After the worker puts the pipe into the automatic welding device, the device can automatically complete the butt joint and assembly welding of the steel pipe, and automatically convey it backward after welding. It can solve the problems of complex operation and low efficiency in the pipeline installation process.

[0004] The scissor lift trucks are located at the bottom of the pipe gallery and arranged in a straight line at a certain distance. A conveying device is designed on the top. After being raised, its pipe conveying device is flush with the post-weld pipe output port of the automatic welding equipment. The continuous pipe output by the automatic welding equipment arrives at the conveying device of the scissor lift truck and is automatically relayed to achieve rapid layout of the pipeline.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] An automated pipeline threading and conveying device for a pipe gallery comprises: a pipe gallery, the pipe gallery being connected to an automatic welding device and being used to transmit continuous steel pipes output by the automatic welding device, a plurality of scissor lifts being fixed inside the pipe gallery, a lifting platform being connected to the top of the scissor lifts, a bracket being fixedly connected to the lifting platform, a first roller, a second roller and a third roller being arranged at an inlet of the bracket, and a conveying device being arranged behind the first roller, the second roller and the third roller.

[0007] Furthermore, the conveying device is fixedly mounted on the bracket.

[0008] Furthermore, the conveying device includes: a shaft, a motor and a V-shaped roller. A motor is arranged on the outside of the V-shaped roller. The V-shaped roller is connected to the motor through the shaft. The motor is used to drive the V-shaped roller to evenly convey the pipeline. The outer end diameter of the V-shaped roller is larger than the inner end, and is used to limit the radial movement of the pipeline.

[0009] Furthermore, the first roller is installed at the frontmost side of the bracket inlet and is V-shaped, and is used to lift the pipeline to a specified horizontal height.

[0010] Furthermore, the second roller is installed on the rear side of the first roller, is 50 mm higher than the first roller, and is V-shaped.

[0011] Furthermore, the third roller is installed on the rear side of the second roller, is 50 mm higher than the second roller, and is V-shaped.

[0012] Furthermore, the heights of the first roller, the second roller and the third roller are increased in sequence until they finally reach the height of the conveying device.

[0013] A pipe gallery automated pipeline threading and conveying method, comprising:

[0014] Step 1: Move multiple scissor lift trucks to the designated location of the pipe gallery to form a scissor lift truck group;

[0015] Step 2: Make the installation height of the pipe gallery pipeline level with the height of the automatic welding equipment;

[0016] Step 3: According to the installation height of the pipe gallery pipeline, lift the lifting platforms of multiple scissor lifts to the specified working height;

[0017] Step 4: Use a crane to transport the steel pipe to be welded to the automatic welding equipment. After the automatic welding equipment automatically welds the steel pipe, the first roller, the second roller and the third roller on the lifting platform of the scissor lift truck lift the welded steel pipe to the required horizontal height of the V-shaped roller, and use the V-shaped roller to transport the welded steel pipe.

[0018] Furthermore, the height at which the steel pipe is lifted by the crane is the same as the height of the automatic welding equipment.

[0019] Furthermore, the V-shaped roller in step 4 can determine the start and stop and the conveying speed according to the welding speed of the automatic welding equipment.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The design of the first, second and third rollers of the present invention rising in sequence can prevent the welded steel pipe seams from being broken by gravity, thus ensuring the stability of transportation.

[0022] 2. The present invention meets the automatic transportation requirements of operations at different heights. Multiple scissor lifts can work remotely and collaboratively. Multiple scissor lifts are automatically linked and adopt an electrical control system to meet the needs of automation. At the same time, the height detection of multiple scissor lifts is achieved through angle sensors. After the steel pipe conveying device is lifted, it is on a horizontal straight line at the same height. After reaching the specified operating height, it has multiple automatic alignment functions and can remotely lock the fixed platform to achieve high-precision lifting control.

[0023] 3. The present invention is not limited by the diversity of pipeline profile specifications, and works in conjunction with pipeline welding equipment to meet the transportation needs of most specifications of steel pipes in pipeline corridor construction. It can adapt to a variety of pipe diameters and weights. After automatic welding, the welded steel pipes are output at a uniform speed. The pipeline transportation module of the scissor lift truck group has automatic start and stop and coordinated speed regulation functions, connects to the automated welding process, and works in conjunction with the scissor lift truck to achieve high-precision linkage control.

[0024] 4. The pipeline of the present invention is directly transported backward after welding in the welding machine. The top conveying mechanism of the scissor lift truck is resistant to high temperature and can adapt to the transportation of pipes of various specifications. The transmission process is smooth and gentle. At the same time, the sagging pipeline needs to be lifted to the same specified horizontal height to avoid damaging the uncooled pipeline weld and ensure the straightness of the pipeline. The pipeline conveying device that works in coordination with the welding equipment, can adapt to various specifications, and can be automatically lifted can improve production efficiency and reduce pipeline operation points.
