Description

Technical Field

[0001] The utility model relates to the field of pipeline installation, and more specifically to an external butt joint device suitable for multi-diameter pipelines. Background Technique

[0002] With the rapid development of modern industry, it has been widely applied in the direction of pipeline installation.

[0003] For example: CN220881226U, a pipeline butt joint device. In the utility model, through the setting of structures such as connecting plates, hexagon head bolts, nuts, etc., the device is made by cutting steel plates, drilling holes with a bench drill and threading with a tap, purchasing finished M14 hexagon head bolts, and fine-tuning the weld butt joint by tightening the hexagon head bolts. The device has low cost, high working efficiency, is relatively light, and can be operated by 2 people to clamp the weld during butt joint. The pipeline can be easily fine-tuned by tightening the hexagon head bolts. After the weld butt joint fine-tuning is completed, the welder can perform spot welding fixation and then remove it. The functions described in this utility model mainly focus on the butt joint of pipeline ports, ignoring the support of the pipeline behind the pipeline port, as well as the auxiliary installation functions of pipeline leveling and displacement.

[0004] For example: CN219673671U, a pipeline construction and maintenance butt joint structure. The utility model discloses a pipeline construction and maintenance butt joint structure, which relates to the technical field of pipeline construction and maintenance, including a support assembly, and a butt joint assembly is arranged on the upper surface of the support assembly. It solves the problem that when the existing pipeline maintenance butt joint device is used, eight bolts need to be rotated to complete the fixation of the pipeline. If the bolts are rotated with greater force, scratches will be caused on the pipeline surface. It realizes that the two groups of pipelines to be butted are placed on the arc grooves opened on the upper surfaces of the two groups of support plates, and by rotating one group of semi-circular plates, the other three groups of semi-circular plates are driven to rotate simultaneously, so that they are clamped on the upper surface of the pipeline, and the pipeline is firmly locked by fastening nails, and by setting anti-slip pad B and anti-slip pad A, when the two groups of pipelines are butted, the movement and deviation can be prevented. When the fixation is completed, then by starting the electric push rod to push the sliding block A, the butt joint operation of the two groups of pipelines can be realized, and by setting positioning rods, the four groups of support plates are on the same horizontal line. The functions described in this utility model mainly focus on the butt joint and horizontal adjustment of pipeline ports, ignoring the support of the pipeline behind the pipeline port, as well as the auxiliary installation functions of pipeline leveling and displacement.

[0027] A multi-diameter pipe external alignment device of the present utility model has the following beneficial effects: The way of pipeline installation operations is determined by the environment and actual on-site conditions. In the working environment on the ground, super-large pipelines are mostly hoisted by cranes, while medium and small pipelines are mostly assisted in installation by workers with the help of support frames. Some pipeline docking devices on the market are mostly structures that fine-tune and correct the docking of the two sides of the pipeline interfaces after the two ends of the pipeline are supported. The present utility model provides a pipeline docking device that can fix the pipeline and can be adjusted up and down. Select the pipeline 221 with the required diameter, and according to its pipeline diameter, the screw-type adjusting support 205 is meshed and rotated and installed on the fixed support B203 and its height is adjusted. Place the pipeline 221 on the fixed support B203, and then push the pipeline 221 forward until it passes through the ring-type shaft seat 207 to the other end. Then start the lead screw motor 209. When its output end rotates, it drives the lead screw shaft B210 to rotate. When the lead screw shaft B210 rotates, it drives the drive shaft seat B211 to linearly move along its axis. When moving, it drives the ring-type shaft seat 207 to rotate along the shaft seat support 206. When the shaft seat support 206 rotates, it sequentially drives the drive shaft seat A208 to rotate along the shaft seat support 206 through the drive shaft seat B211 and the lead screw shaft B210. When the drive shaft seat A208 rotates, it drives the lead screw motor 209 to rotate. The purpose is to always ensure that the rotation of the ring-type shaft seat 207 is within effective control when the lead screw motor 209 drives the lead screw shaft B210 to rotate. When the ring-type shaft seat 207 rotates, it simultaneously drives the connecting rod limit block A213, the connecting rod limit block B216, and the connecting rod limit block C219 to rotate. When the connecting rod limit block A213 rotates, it drives the connecting rod A212 to rotate along the shaft seat support 206. When the connecting rod A212 rotates, it drives the fixed wheel A214 to rotate inward. When the connecting rod limit block B216 rotates, it drives the connecting rod B215 to rotate along the shaft seat support 206. When the connecting rod B215 rotates, it drives the fixed wheel B217 to rotate inward. When the connecting rod limit block C219 rotates, it drives the connecting rod C218 to rotate along the shaft seat support 206. When the connecting rod C218 rotates, it drives the fixed wheel C220 to rotate inward. When the fixed wheels A214, B217, and C220 move inward synchronously, they finally synchronously contact the outer surface of the pipeline 221, and finally fix the pipeline 221. At this time, under restraint, the axis of the pipeline 221 and the axis of the ring-type shaft seat 207 are in a concentric and coaxial state. Then stop the operation of the lead screw motor 209. When it is necessary to adjust the up and down position of the pipeline 221, start the lead screw motor A107. Its output end drives the lead screw shaft A110 to linearly move up and down along its output axis. When moving, it drives the shaft connection plate D111 and the triangular connection plate 119 to move up and down with it. To increase its stability, when the shaft connection plate D111 and the triangular connection plate 119 move up and down, they drive the shaft fixing group A116, the shaft fixing group B117, and the shaft fixing group C118 to move up and down with them. When moving, it drives the shaft fixing group A116 to slide up and down along the shaft connection plate C105.Drive shaft fixing group B117 and shaft fixing group C118 move up and down along shaft connecting plate A103. Shaft connecting plate D111 drives the second docking mechanism 2 to move up and down through shaft connecting plate E112. When it is necessary to rotate the pipeline 221, directly hold and rotate the second docking mechanism 2 by hand. The second docking mechanism 2 rotates along shaft connecting plate E112 through the bolt-type fixing member 204 therein. When rotating, the shaft connecting plate F201 in the second docking mechanism 2 rotates along ball seats A113, B114, and C115, ensuring the supporting force and enabling it to rotate easily on the balls in ball seats A113, B114, and C115, and finally matching and docking with the docked pipeline.

Changes, modifications, additions or substitutions made by those of ordinary skill in the art within the scope of the essence of the present utility model also belong to the protection scope of the present utility model.
