Firstly, the two supporting plates which are opposite in the front-back direction abut against the corresponding pipelines, and the axes of the left pipeline and the right pipeline are preliminarily collinear with the corresponding supporting plates as the benchmark in the mode that the two alignment columns are clamped into the alignment cylinders; afterwards, the axes of the two pipelines are collinear through the mode that the datum plates abut against the corresponding pipeline steel pipes and the mode that the datum blocks control the gap between the two pipelines, in conclusion, through the three modes, it is guaranteed that the axes of the left pipeline and the right pipeline are collinear and aligned, and the gap between the left pipeline and the right pipeline is controlled to be a specified value. Meanwhile, the two sets of supporting plates are far away from the connecting position of the pipeline, and interference to the butt joint process due to the too long pipeline is avoided.

Description

Technical Field

[0001] The invention relates to the technical field of pipe docking installation, and in particular to a pipe installation support device for a heating pipe network. Background Art

[0002] The heating network is an important part of the urban or regional heating system. It transports heat energy from heat sources (such as thermal power plants, boiler rooms, etc.) to users (such as residences, commercial buildings, industrial facilities, etc.) through a complex pipeline network to ensure winter heating. The heating network consists of heat sources, pipelines, heat exchange stations and user-end equipment. The pipelines are composed of insulation protective layer, insulation layer and steel pipe from the outside to the inside.

[0003] During the installation of pipelines, it is necessary to reasonably design the direction and layout of the pipelines according to the location of the heat source, the distribution of users and the characteristics of the terrain, connect multiple sections of pipelines in sequence for installation, and complete the layout and laying of the pipeline network. At present, when installing a single pipeline, the pipeline to be installed is first hoisted to the designated location (usually a laying pit excavated in advance) by external lifting equipment, and the openings of the two pipelines are made to face each other. It should be noted that the interfaces of the two connected pipelines expose the steel pipes. Then the external lifting equipment is controlled to cooperate with manual adjustment step by step so that the interfaces of the two pipelines are aligned close to each other, and the gap of the specified value is maintained at the two pipe openings to avoid bending or rupture of the pipeline due to thermal expansion during subsequent use, to ensure the welding process requirements and to retain room for installation adjustment, thereby ensuring that the two connected pipelines are tight and reliable. See Figure 8 , then lock the connection of the two pipes, and finally manually connect the connection of the two pipes (currently the connection method of welding the steel pipe connection of the two pipes is usually adopted).

[0004] The current installation process has the following problems: the overall accuracy of placing and installing the pipelines manually with external lifting equipment is poor, and it is difficult to ensure the overall coaxiality of the two pipelines. Secondly, since the pipeline length is usually in the range of 6 to 12 meters, it is difficult to ensure that the overall axes of the two pipelines are in line by only adjusting the coaxiality of the connection between the steel pipes on the two pipelines during the installation process. At the same time, it is difficult to control the circumferential gap position of the two pipelines to be consistent, so it is easy to affect the subsequent connection process and subsequent use process due to poor accuracy of the docking process.

[0018] In summary, the present invention includes at least one of the following beneficial effects: 1. In the present invention, firstly, two front and rear opposing support plates are used to press against corresponding pipelines, and two alignment columns are inserted into the alignment cylinder to make the axes of the left and right pipelines initially collinear with the corresponding support plates as the reference. Then, the reference plate is pressed against the corresponding pipeline steel pipe and the reference block is used to control the gap between the two pipelines to ensure that the axes of the two pipelines are collinear. In summary, through the above three methods, it is ensured that the left and right pipelines remain collinear and the gap between them is controlled to a specified value. At the same time, by keeping the two groups of support plates away from the connection of the pipelines, interference with the docking process due to excessively long pipelines is avoided.

[0019] 2. In the present invention, the rectangular plate 1 on the right is installed on the rectangular plate 2 by plugging, and the front side plate is installed on the rectangular tube by plugging.

[0020] 3. In the present invention, the protective layers at the connection points of the two pipelines are pressed against the adjacent reference plates to preliminarily control the butt-jointing installation gap of the two pipelines, and then the rectangular sections of multiple reference blocks are inserted between the two pipeline openings to ensure that the installation gap of the two pipelines is the required value. In the above process, the steel pipe part of the pipeline is pressed against by four reference plates above and below, and the arc surface of the reference block is pressed against the chamfered part of the pipeline connection to ensure that the steel pipes of the pipeline are coaxial. At the same time, the vertical section of the reference plate is opposite to the protective layer of the pipeline on the left and right at this time, thereby improving the accuracy of the butt-jointing installation process of the two pipelines.

[0021] Fourth, the support plate in the present invention is arranged in a horizontal plane, and the reference plate is arranged in a vertical plane. At the same time, through the meshing between gear 2 and the teeth on the two rotating frames, the circular frame formed drives all the reference blocks to rotate synchronously, so that the reference blocks, the reference plates and the support plates are staggered with each other in the vertical circumferential plane from left to right, ensuring the coaxiality of the two pipes. At the same time, the gap distances at each location of the connection between the two pipes meet the requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0033] like Figure 1 and Figure 5 As shown, a heating network pipeline installation support device comprises: Rectangular plate 1, the number of the rectangular plates 1 is two, the two rectangular plates 1 are arranged symmetrically on the left and right, the right end surface of the left rectangular plate 1 is fixedly provided with a rectangular plate 2 through a connecting column 1, the right end surface of the rectangular plate 2 2 is penetrated by two guide holes 3 which are symmetrical front and back and the axis extends from right to left, and the left end surface of the right rectangular plate 1 is fixedly provided with two guide columns 30 which are symmetrical front and back.

[0034] like Figure 1 and Figure 2 As shown, the two rectangular plates 1 are both provided with a reference unit 4, and the two reference units 4 are symmetrical on the left and right. The reference unit 4 includes a U-shaped frame 40. The rectangular plate 1 is provided with a U-shaped frame 40 with an opening downward that slides up and down through a sliding rod with a vertical axis. The two vertical sections of the U-shaped frame 40 are both provided with an arc-shaped support plate 41, and the inner arc surface of the support plate 41 faces the pipeline. The reference unit 4 also includes a driving group 43 for driving the support plate 41 to press against the pipeline.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the rectangular plate 2 is provided with a positioning mechanism 5 for docking two pipes, and the positioning mechanism 5 includes side plates 50, and the front and rear sides of the rectangular plate 2 are both provided with side plates 50, and the opposite surfaces of the two side plates 50 are both slidably provided with horizontal plates 500 symmetrically arranged up and down, and the front end surface of the rear horizontal plate 500 is fixedly provided with a rectangular cylinder 501, and a connecting rod is slidably penetrated through the rectangular plate 2, and the lower end surface of the connecting rod is fixedly connected to the upper rectangular cylinder 501, and the front end surface of the rectangular cylinder 501 is fixedly provided with a plug-in column 502, and the rear end surface of the front horizontal plate 500 is provided with a plug-in groove, and the left and right sides of the rectangular cylinder 501 are both provided with L-shaped reference plates 503, and the horizontal sections of the two reference plates 503 opposite to each other are adjacent, and a plurality of circumferentially uniformly distributed reference blocks 504 are commonly provided between the two rectangular cylinders 501, and the positioning mechanism 5 also includes a driving unit 53 for driving the reference plate 503 to press against the pipeline.

[0036] During the installation and docking process, one of the pipes is in a fixed state and the other pipe is in a state to be installed and docked. During the installation process, the pipe is lifted and docked with the fixed pipe by an external existing lifting equipment (not shown in the figure). The following process is described with the left pipe being fixed and the right pipe to be installed.

[0037] During operation, after the external lifting equipment lifts the right pipe and moves it to a position opposite to the left pipe, the rectangular plate 1 and the rectangular plate 2 are manually placed above the two pipes, and the left rectangular plate 1 is located above the left pipe, the right rectangular plate 1 is located above the right pipe, and the rectangular plate 2 is located above the docking position of the two pipes. The right rectangular plate 1 is moved to the left so that the guide column 30 thereon is inserted into the guide hole 3, and the rectangular plate 1 and the rectangular plate 2 are moved from top to bottom to be placed so that the corresponding support plates 41 are moved to the front and rear sides of the pipe. It should be noted that after the rectangular plate 1 is placed, the rectangular plate 1 is detachably connected to the external cylinder (not shown in the figure) by screws or other means, and the rectangular plate 1 is driven downward by the external cylinder operation.

[0038] The operation of the external cylinder causes the rectangular plate 1 and the rectangular plate 2 to move downward synchronously, and the driving group 1 43 causes the two front and rear opposite support plates 41 to press against the corresponding pipes, thereby ensuring that the axes of the two pipes are initially collinear.

[0039] Afterwards, the two horizontal plates 500 on the front side plate 50 are respectively plugged into the corresponding plug-in columns 502, and the driving unit 53 works, so that the rectangular tube 501 drives the corresponding reference plate 503 to move synchronously, and the two rectangular tubes 501 approach each other, and the reference plate 503 moves to contact and press with the pipeline steel pipe, and the vertical section of the reference plate 503 is opposite to the left and right of the pipeline protective layer. Then, the external lifting equipment works to move the right pipeline to the left, so that the protective layer of the pipeline is in close contact with the corresponding vertical section of the reference plate 503, and at the same time, the reference block 504 moves between the two pipelines to control the gap between the two pipelines. In summary, through the tightening of the support plate 41, the tightening of the reference plate 503 and the gap control of the reference block 504, the axes of the two pipelines are collinear and the gap at the connection between the two meets the installation requirements, and then the staff performs the connection operation between the two pipelines (such as welding and other operations).

[0040] like Figure 1 and Figure 2 As shown, the reference unit 4 also includes a sliding block 42, the vertical section of the U-shaped frame 40 is provided with a sliding block 42 for sliding up and down, the sliding block 42 is provided with a clamping rod 420 with an axis extending from front to back for sliding forward and backward, the support plate 41 is provided on the corresponding clamping rod 420, and a spring 421 sleeved on the clamping rod 420 is fixedly provided between the support plate 41 and the sliding block 42, the driving group 43 includes an inclined plate 430, and the front and rear end surfaces of the rectangular plate 1 are fixedly provided with the inclined plate 430 through the L-shaped frame, and the same U The two inclined plates 430 corresponding to the rectangular frame 40 are symmetrical front to back. Taking the front inclined plate 430 as an example, the front inclined plate 430 is inclined upward from front to back, and a matching plate 431 with the same inclination direction as the inclined plate 430 is fixedly provided on the end surface of the clamping rod 420 close to the inclined plate 430. The rectangular plate 1 slides up and down and penetrates a vertical rod 432. A clamping plate 433 is fixedly provided on the lower end surface of the vertical rod 432. A spring 2 434 mounted on the vertical rod 432 is fixedly provided between the clamping plate 433 and the rectangular plate 1.

[0041] like Figure 1 and Figure 2As shown, the alignment mechanism 5 also includes an alignment group 51 arranged between the two side plates 50 and all the support plates 41, and the alignment group 51 includes a fixed block 510. The opposite back surfaces of the two side plates 50 are fixedly provided with the fixed blocks 510, and an alignment cylinder 511 with an axis extending from left to right is installed on the fixed block 510 for sliding left and right. The opposite surfaces of the two opposite support plates 41 are fixedly provided with an alignment column 512 with an axis extending from left to right through a connecting plate.

[0042] like Figure 1 and Figure 2 As shown, a pushing round block 513 is fixedly mounted on the alignment column 512 on the right side, a mounting round block located on the left side of the fixed block 510 is fixedly mounted on the alignment cylinder 511, a spring 514 mounted on the alignment cylinder 511 is fixedly mounted between the mounting round block and the fixed block 510, and the left and right openings of the alignment cylinder 511 are chamfered.

[0043] During operation, in the process of moving the rectangular plate 1 and the rectangular plate 2 from top to bottom, the support plate 41 contacts the outer wall of the pipe. As the rectangular plate 1 continues to move downward, the support plate 41 gradually approaches the adjacent vertical section of the corresponding U-shaped frame 40, and the spring 1 421 is compressed. Finally, the inner arc surface of the support plate 41 fits the outer wall of the pipe. The elastic force generated by the deformation of the spring 1 421 causes the support plate 41 to press the pipe tightly. The two support plates 41 on the same U-shaped frame 40 cooperate with each other to support the U-shaped frame 40 and the corresponding rectangular plate 1. Secondly, in the above-mentioned moving process, the rectangular plate 1 drives the corresponding clamping plate 433 to move downward synchronously, and the clamping plate 433 stops moving after contacting the pipe. As the rectangular plate 1 continues to move downward, the spring 2 434 is compressed, and the overall device is supported by the elastic force generated by the deformation of the spring 2 434, which is convenient for the subsequent support plate 41 to press against the pipe and guide the alignment installation process.

[0044] Afterwards, the external cylinder works to drive the rectangular plate 1 to move downward continuously, and the inclined plate 430 on the rectangular plate 1 moves downward continuously relative to the U-shaped frame 40. Through the cooperation between the inclined plate 430 and the corresponding matching plate 431, the clamping rod 420 drives the support plate 41 to completely clamp the pipeline, and through the simultaneous downward movement of the two inclined plates 430 on the same rectangular plate 1, the pipeline is located in the middle position in the front and rear direction of the U-shaped frame 40. In summary, the axis of the support plate 41 is colinear with the axis of the pipeline and the rectangular plate 1 is located directly above the pipeline.

[0045] The right rectangular plate 1 is pushed to the left, and the rectangular plate 1 drives the alignment column 512 to move left synchronously through the U-shaped frame 40 thereon. The alignment column 512 moves and inserts into the alignment cylinder 511, and makes the pushing block 513 thereon contact with the alignment cylinder 511. As the rectangular plate 2 continues to move, the right alignment column 512 pushes the alignment cylinder 511 to move left synchronously by pushing the block 513. Therefore, the left alignment column 512 is inserted into the alignment cylinder 511 through the left end opening of the alignment cylinder 511, so that the left support plate 41, the U-shaped frame 40, the alignment column 512 and the alignment cylinder 511 form a rectangular frame together, and cooperate with the tightening process of the support plate 41, so that the left and right pipeline axes are initially collinear with the corresponding support plate 41 as the reference. In the above process, the spring three 514 is stretched, so the alignment cylinder 511 can be reset by the elastic force generated by the deformation of the spring three 514.

[0046] like Figure 1 , Figure 3 and Figure 4 As shown, the alignment mechanism 5 also includes an adjustment group 52 arranged on the rectangular tube 501, and the adjustment group 52 includes a tooth plate 520. Two tooth plates 520 distributed front and back are slidingly arranged in the rectangular tube 501, and the tooth plate 520 is fixedly connected to the adjacent reference plate 503. A gear 521 meshing with the tooth plate 520 is rotatably arranged in the rectangular tube 501 through a central axis vertical to the axis, and the two tooth plates 520 are symmetrical about the front and back axis of the central axis. Two strip grooves 522 that are symmetrical front and back and connected to the inner cavity are provided on the opposite back sides of the two rectangular tubes 501. Bolts 523 that penetrate the corresponding strip grooves 522 are fixedly arranged on the tooth plate 520, and nuts are threadedly installed on the bolts 523.

[0047] Before the alignment installation, the spacing between the two reference plates 503 on the same rectangular tube 501 is adjusted according to the required distance of the protective layer at the joint of the heating pipeline. First, the nut is rotated to release the fixation of the bolt 523 and the tooth plate 520. Then, the reference plate 503 is moved and the corresponding tooth plate 520 is driven to move synchronously. The engagement between the tooth plate 520 and the corresponding gear 521 enables the other reference plate 503 to move synchronously, and the two reference plates 503 are always symmetrical on the left and right. After the spacing between the two reference plates 503 is controlled to be a specified value, the nut is manually tightened to fix the tooth plate 520, completing the adjustment operation of the reference plate 503. In the subsequent downward placement process of the rectangular plate 1, the reference plate 503 is located above the two pipeline steel pipe parts.

[0048] like Figure 1 and Figure 3As shown, the driving unit 53 is arranged on two side plates 50, and the driving unit 53 includes a bidirectional threaded rod 530. The opposite surfaces of the two side plates 50 are rotatably provided with a bidirectional threaded rod 530 with a vertical axis through a connecting block. The bidirectional threaded rod 530 passes through the corresponding horizontal plate 500 and is threadedly matched with the horizontal plate 500. The bidirectional threaded rod 530 is connected to an external motor.

[0049] After the distance adjustment of the reference plate 503 is completed, the reference plate 503 is located above the two steel pipe parts of the pipeline, and then the external motor works to drive the bidirectional threaded rod 530 to rotate synchronously, and the cooperation between the bidirectional threaded rod 530 and the corresponding horizontal plate 500 makes the two horizontal plates 500 on the same side plate 50 approach each other, and the horizontal plate 500 drives the corresponding rectangular tube 501 to move synchronously, and the two rectangular tubes 501 respectively drive the corresponding reference plates 503 to approach the pipeline. Because before this, the rectangular plate 22, the rectangular tube 501 and the rectangular plate 11 are all located directly above or below the pipeline through the reference unit 4, so the four reference plates 503 above and below all press the steel pipe part of the pipeline to ensure that the steel pipe of the pipeline is coaxial, and at the same time, the vertical section of the reference plate 503 is opposite to the protective layer of the pipeline on the left and right.

[0050] Afterwards, the external lifting equipment lifts the right pipe and moves it to the left. The protective layer of the right pipe contacts the right reference plate 503 and pushes the reference plate 503 and the rectangular tube 501 to move to the left synchronously, so that the left reference plate 503 and the protective layer of the left pipe are finally close to the foundation, so as to preliminarily control the docking installation gap between the two pipes. In the above process, a rectangular frame is formed by the reference plate 503, the rectangular tube 501, the horizontal plate 500 and the side plate 50, which improves the stability during the docking installation process.

[0051] like Figure 1 , Figure 3 and Figure 5 As shown, the alignment mechanism 5 also includes a mounting rod 54, and the rectangular tube 501 is slidably penetrated by the mounting rod 54 up and down, and circular plates 540 are fixedly provided on the opposite back surfaces of the two mounting rods 54, and a spring 541 sleeved on the mounting rod 54 is fixedly provided between the circular plate 540 and the rectangular tube 501, and arc frames 542 are fixedly provided on the opposite surfaces of the two mounting rods 54, and a semicircular rotating frame 543 is slidably provided on the arc frame 542, and the left end face of the rotating frame 543 is fixedly connected to the corresponding reference block 504 through an L-shaped connecting frame.

[0052] like Figure 5As shown, the reference block 504 is composed of an isosceles trapezoidal segment and a rectangular segment in sequence along the circumferential surface of the rotating frame 543 pointing to the axis of the rotating frame 543, and the two corresponding reference plates 503 on the left and right are symmetrically distributed with the reference block 504 as the center. The inclined surface of the isosceles trapezoidal segment of the reference block 504 fits with the inclined surface of the pipeline interface, and the thickness of its rectangular segment is the same as the gap distance between the two pipelines.

[0053] During operation, as the two rectangular cylinders 501 approach each other up and down, the rectangular cylinder 501 drives the mounting rod 54 and the arc frame 542 thereon to move synchronously, and the upper and lower arc frames 542 drive the rotating frame 543 thereon to move synchronously. When the reference block 504 on the rotating frame 543 moves to contact the steel pipe of the right pipeline, it stops moving. As the rectangular cylinder 501 continues to move, the spring four 541 is stretched, and the elastic force generated by the deformation of the spring four 541 causes the reference block 504 to press against the pipeline. When the reference plate 503 presses against the steel pipe of the pipeline and begins to push the right pipeline, the right pipeline pushes the right reference plate 503 to move left. In this process, The reference plate 503 drives the rotating frame 543 and the reference block 504 to move synchronously through the rectangular tube 501. When the left reference plate 503 approaches the pipeline protective layer, the reference block 504 moves to the middle position of the two pipelines. The elastic force generated by the deformation of the spring four 541 makes the reference block 504 stuck between the steel pipes of the two pipelines, and the chamfer of the steel pipe fits with the inclined surface of the isosceles trapezoidal section on the reference block 504, and the rectangular section of the reference block 504 is located between the steel pipes of the two pipelines. The reference plate 503 and the reference block 504 prevent the right pipeline from continuing to move, ensuring that the spacing between the steel pipe openings of the two pipelines is the required value, thereby ensuring the accuracy of subsequent connection and installation.

[0054] like Figure 1 , Figure 5 and Figure 6 As shown, the driving unit 53 also includes a driving group 2 arranged on the upper arc frame 542, and the driving group 2 includes a fixed frame 531. An L-shaped fixed frame 531 is fixedly arranged on the rear side of the upper arc frame 542. The vertical section of the fixed frame 531 is rotatably provided with a rotating shaft with an axis extending from left to right. A gear 2 533 is fixedly sleeved on the rotating shaft. A plurality of circumferentially evenly distributed teeth are fixedly arranged on the circumferential surface of the rotating frame 543, and the teeth on the rotating frame 543 mesh with the gear 2 533. The fixed frame 5 A rectangular bar 534 is fixedly provided on the right end face of the vertical section 31, and a transmission shaft 535 with a vertical axis is rotatably provided on the rectangular bar 534. Bevel gears 536 are fixedly provided on the lower end of the transmission shaft 535 and the rotating shaft, and the two bevel gears 536 are meshed with each other. A platform plate 537 is fixedly provided on the rear side plate 50, and a transmission column 538 is rotatably provided on the platform plate 537. The transmission shaft 535 is slidably provided on the transmission column 538 up and down, and the transmission column 538 and the rear bidirectional threaded rod 530 are driven by a sprocket chain.

[0055] like Figure 6 As shown, the two lower end surfaces of the upper rotating frame 543 are both provided with card slots, and the two upper end surfaces of the lower rotating frame 543 are both fixedly provided with card columns 544 that cooperate with the card slots, and both ends of the rotating frame 543 are made of rubber material.

[0056] It should be noted that when the reference block 504 is inserted between the steel pipes of the two pipelines, the horizontal section of the reference plate 503 is not in close contact with the steel pipes, and the rectangular tube 501 still needs to continue to move.

[0057] In the process of the rectangular tube 501 driving the corresponding rotating frame 543 to move downward, the sprocket chain transmission between the rear bidirectional threaded rod 530 and the transmission column 538 makes the transmission column 538 rotate synchronously, and the transmission column 538 drives the transmission shaft 535 to rotate synchronously. The transmission shaft 535 drives the rotating shaft and the gear 2 533 to rotate synchronously through the meshing between the bevel gear 536 on the transmission shaft and the bevel gear 536 on the rotating shaft. The rotating frame 543 rotates synchronously through the meshing between the gear 2 533 and the teeth on the upper rotating frame 543. At the same time, the two rotating frames 543 approach each other, and the lower rotating frame 543 is manually adjusted. The elasticity of the rubber material allows the clamping column 544 on the lower rotating frame 543 to be clamped into the clamping groove of the upper rotating frame 543, so that the two rotating frames 543 form a circular frame together, which is convenient for the upper rotating frame 543 to drive the lower rotating frame 543 to rotate synchronously, and the axis of the frame is in line with the axis of the pipeline. Then, as the rectangular tube 501 continues to move, the engagement between the gear 2 533 and the teeth on the two rotating frames 543 makes the formed circular frame drive all the reference blocks 504 to rotate synchronously, so that the reference blocks 504, the reference plate 503 and the support plate 41 are staggered from each other in the vertical circumferential plane from left to right (see Figure 7 ), ensure the coaxiality of the two pipes and the gap distance between them meets the requirements.
