Description

Technical Field

[0001] The utility model relates to the technical field of pipeline installation engineering, in particular to a pipeline installation auxiliary device for building installation engineering. Background Art

[0002] Gases, liquids or fluids with solid particles in the factory are all transported through pipelines. Generally, after the fluid is pressurized by equipment such as blowers, compressors, pumps or boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, or it can also be transported by the pressure or gravity of the fluid itself.

[0003] Due to the influence of factors such as processing, transportation and installation, the length of the pipeline is limited, and multiple sections need to be spliced to complete the installation of the whole pipeline. Most pipeline splicing methods adopt flange connection or welding. Circular pipelines are prone to shaking during splicing, which brings certain trouble to the splicing work. Moreover, high-temperature, high-pressure fluids and toxic and harmful chemical substances are relatively common in the fluids transported by pipelines in the factory. If the pipeline installation is not in place, the fluid in the pipeline may leak, posing risks of polluting the environment, harming the human body and affecting the operation of equipment around the pipeline. Therefore, during the pipeline installation construction process, pipeline clamping tools are usually used to position the pipelines to be spliced, and then splicing is carried out to improve the installation accuracy.

[0004] In the existing pipeline installation devices, for example, the Chinese utility model patent with the application number CN202022679190.8 discloses a butt joint fixer for gas pipeline construction, including fixing pieces, sliders, support plates, connecting plates and positioning bolts. There are two fixing pieces arranged at intervals. The sliders are fixedly connected to the bottom of the fixing pieces. The support plates are placed below the fixing pieces. A chute is opened on one side of the support plate close to the fixing piece. The sliders are inserted into the chute and are slidably connected with the chute. The connecting plates are fixedly connected to the tops of the sliders. The positioning bolts are threadedly connected to the connecting plates and are clamped with the tops of the support plates. This patent also has the following defects: 1. The bottom of this device is supported by fixed piles, and the device is not convenient to move; 2. The installation heights of pipelines in different pipelines and different positions may vary. This device uses telescopic sleeves and springs to support the support plate, but the height of the support plate cannot be fixed, and it cannot be used as a support platform for the pipeline to be installed and adjust the height of the pipeline; 3. When there is an angle between the pipeline and the ground or the ground is uneven or the pipeline is installed on a slope, this device cannot adjust the support plate to be horizontal; 4. This device can only be used for butt joint of two pipelines with the same diameter. For pipelines with different diameters, this device cannot coaxially fix the butting joints of the two pipelines.

[0036] Furthermore, the vehicle body 1 includes a vehicle frame 11 and four universal wheels 12 provided below the vehicle frame 11.

[0037] The working principle of the present utility model:

[0038] In this device, the movable vehicle body 1 serves as the moving device and the support base of the pipeline installation auxiliary device. The height on the workbench surface 4 is adjusted by the lifting device 2 and the angle adjustment device 3 on the vehicle body 1 to adapt to the installation height of the pipeline 9; meanwhile, taking the hinge axis between the top of the lifting device 2 and the workbench surface 4 as the rotation axis, the angle of the workbench surface 4 is adjusted by the angle adjustment device 3 to adapt to the angle difference between the pipeline 9 during installation and the ground. Two clamping members are provided on each of the fixed clamping device 6 and the movable clamping device 7 installed on both sides of the workbench surface 4. The two sections of the pipeline 9 are clamped by the four clamping members divided into two groups. The four clamping plates symmetrically arranged on the two clamping members form a rhombus structure, and the pipeline 9 is clamped by four support points, so that the two docking ports are coaxial when the two sections of the pipeline 9 are docked; the docking of the pipeline to be installed is brought closer to the docking port of the installed pipeline 9 for connection by driving the movable clamping device 7 to slide on the lateral movement chute 42 through the closing of the lateral movement adjustment device 8.

[0039] The lifting device 2, the angle adjustment device 3, and the lateral movement adjustment device 8 are all of scissor jack structures. By rotating the handle of the scissor jack adjustment screw, the rhombus structure of the scissor jack is expanded or closed, thereby realizing the lifting, angle adjustment of the workbench surface 4, and lateral movement of the movable clamping device 7. The bottom of the lifting device 2 is fixed to the vehicle body 1 to restrict the left and right offset of the workbench surface 4, so that it can only lift and rotate; when the lifting device 2 and the angle adjustment device 3 rotate simultaneously, the workbench surface 4 is in a lifting state; when the lifting device 2 does not move and the angle adjustment device 3 rotates, the workbench surface 4 is in a state of plate rotation.

[0040] Before clamping the pipeline 9, the second clamping member 73 can rotate the adjusting nut 736 to adjust the opening degree of the second clamping plate 735 according to the diameter of the pipeline 9 to adapt to pipelines 9 with different diameters. By rotating the adjusting nut 736, the clamping plate adjusting screw 734 expands and contracts, changing the position of the hinge seat at the tail of the clamping plate adjusting screw 734 in the flaring hole 733.

[0041] The beneficial effects of the present utility model compared with the prior art:

[0042] 1. The bottom of the utility model is moved by the universal wheel 12 to assist the moving work surface 4, so that the construction personnel can adjust the position of the device and improve the installation efficiency of the pipeline 9.

[0043] 2. The utility model can adjust the height of the work surface 4 by adjusting the lifting device 2 and the angle adjustment device 3 at the same time to adapt to the installation height of different pipelines 9.

[0044] 3. The utility model can adjust the angle of the work surface 4 by adjusting the angle adjustment device 3. If there is an angle between the pipeline 9 and the ground or the ground is uneven or the pipeline is installed on a slope, the angle difference between the pipeline 9 and the ground can be adapted by adjusting the angle of the work surface 4.

[0045] 4. The utility model clamps a pipe 9 by four first clamping plates 622 or four second clamping plates 735. The four clamping plates symmetrically form a diamond structure. The pipe 9 is guided by the plate surfaces of the clamping plates so that the pipe 9 is located at the center position inside the four clamping plates. Two groups of four clamping plates each clamp two pipes 9 respectively so that the butt joints of the two pipes 9 are located at the coaxial position, which is convenient for the butt joint installation of the two pipes 9 and is also suitable for the butt joint installation of two pipes 9 of different diameters.

[0046] 5. Before clamping the pipe 9, the second clamping member 73 can adjust the opening of the second clamping plate 735 by rotating the adjusting nut 736 according to the diameter of the pipe 9 to adapt to pipes 9 of different diameters, so that the second clamping plate 735 can clamp pipes 9 of different diameters, which is convenient for fixing pipes 9 of different diameters and has a wide range of applicability.

[0047] 6. After adjustment, the lifting device 2 and the angle adjustment device 3 of the utility model are self-locking through the adjustment screw of the scissor jack. The work surface 4 will not drop when under pressure, and can be used as a temporary support frame for the pipeline 9. When there is no temporary support structure for the pipeline to be installed, the pipeline 9 can be supported by two sets of the device, and the pipeline 9 can be adjusted to move horizontally and dock together.

[0067] In order to enable those skilled in the art of the present technology to better understand the technical solution of the present utility model, the following will describe its detailed implementation manners in conjunction with the accompanying drawings.

[0068] Embodiment 1:

[0069] As Figures 1-4 shown in, 8, 9, a pipeline installation auxiliary device for construction and installation projects includes a vehicle body 1, a lifting device 2, an angle adjusting device 3, a workbench surface 4, and two sets of clamping devices 5.

[0070] In an embodiment, as Figures 1-4 shown, four universal wheels 12 with a self-locking function are installed below the frame 11 of the vehicle body 1. The universal wheels 12 facilitate the construction workers to push the device to adjust the position.

[0071] In an embodiment, as Figures 1-4 shown, the lifting device 2 is used to lift the working table surface 4. The bottom of the lifting device 2 is fixed to the left side of the vehicle body 1 to ensure that the working table surface 4 does not shake left and right; the angle adjustment device 3 is used to lift the working table surface 4 and adjust the angle of the working table surface 4; when the angle adjustment device 3 adjusts the angle of the working table surface 4, the working table surface 4 rotates around the hinge axis between the top of the lifting device 2 and the working table surface 4.

[0072] In an embodiment, as Figures 1-4 shown, the fixed clamping device 6 is installed in a chute 41 on the left side of the working table surface 4, and the movable clamping device 7 is slidably installed left and right in a transverse chute 42 on the right side of the working table surface 4. The movable clamping device 7 adjusts its left and right position through a transverse movement adjustment device 8. The left and right sliding range of the movable clamping device 7 in the transverse chute 42 is not less than 200 mm, which is convenient for the movable clamping device 7 to drive the pipeline 9 to be installed to dock with one end of the installed pipeline 9 during the sliding process, reducing the docking difficulty of the pipeline 9.

[0073] In an embodiment, as Figure 1 、 4 shown, the fixed clamping device 6 includes a first adjustment screw 61 and two first clamping members 62. The thread directions at both ends of the first adjustment screw 61 are opposite. When turning the handle of the first adjustment screw 61, the two first clamping members 62 move in opposite directions, clamping the pipeline 9 when closing and loosening the pipeline 9 when separating.

[0074] In an embodiment, as Figure 4 shown, the movable clamping device 7 includes a slide plate 71, a second adjustment screw 72 and two second clamping members 73.

[0075] The depth of the second chute 711 on the slide plate 71 is the same as the depth of the first chute 41. The through holes at both ends of the first chute 41 and the second chute 711 are larger than the diameter of the first adjustment screw 61, and are respectively used to install the first adjustment screw 61 and the second adjustment screw 72 and form a limit for the adjustment screw. The waist-shaped grooves 421 on the front and rear sides of the transverse chute 42 are used to provide a moving space for the second adjustment screw 72 and the adjustment screw of the transverse movement adjustment device 8 to ensure that the movable clamping device 7 slides without obstruction.

[0076] The structure of the second adjustment screw 72 is the same as that of the first adjustment screw 61, and the thread directions at both ends are opposite. When turning the handle of the second adjustment screw 72, the two second clamping members 73 move in opposite directions, clamping the pipeline 9 when closing and loosening the pipeline 9 when separating.

[0077] In the embodiment, as Figures 1-4 shown, the first clamping member 62 and the second clamping member 73 have the same structure, and both include a first moving bracket 621 and two first clamping plates 622.

[0078] The two first clamping plates 622 are arranged in a horizontal V-shaped structure, and the four first clamping plates 622 on the two groups of first clamping members 62 or second clamping members 73 form a diamond structure to clamp the pipeline 9 at 4 positions. The included angle range of the two first clamping plates 622 is 45-60 degrees, and a rubber layer can be arranged inside the first clamping plates 622 to protect the surface of the pipeline 9.

[0079] The width of the first moving bracket 621 is adapted to the widths of the first chute 41 and the second chute 711. The tops of the two first moving brackets 621 on the two first clamping members 62 or second clamping members 73 are arranged in a staggered manner, so that when the two groups of first clamping members 62 or second clamping members 73 are closed, the two groups of first clamping plates 622 clamp the pipeline 9 in a staggered manner. The two groups of first clamping plates 622 can clamp a pipeline 9 with a diameter smaller than the horizontal width of the two first clamping plates 622, increasing the clamping size range of the first clamping member 62 and the second clamping member 73 to be applicable to the installation of pipelines 9 of different sizes.

[0080] In the embodiment, as Figures 1-4 shown, the lifting device 2, the angle adjusting device 3 and the transverse movement adjusting device 8 are all scissor jacks; they all include a lower support, an upper support, two adjusting blocks, an adjusting screw, two sets of upper support rods and two sets of lower support rods made of metal materials. The two sets of upper support rods and the two sets of lower support rods are arranged in a diamond shape. The lower ends of the two sets of lower support rods are hinged to the lower support, the upper ends of the two sets of upper support rods are hinged to the upper support, the lower ends of the two sets of upper support rods and the lower ends of the two sets of lower support rods are respectively connected through two adjusting blocks, and both ends of the adjusting screw are threadedly engaged and connected in the threaded holes of the two adjusting blocks. The thread directions of both ends of the adjusting screw are opposite.

[0081] The upper support rods and the lower support rods of the lifting device 2 and the angle adjusting device 3 are both composed of two parallel connecting rods. The two parallel connecting rods and the support and the adjusting block form a parallelogram mechanism to ensure that the upper support is parallel to the vehicle frame 11. The lengths of the lower support and the upper support of the lifting device 2 and the angle adjusting device 3 are not less than 200 mm, increasing the installation length and area of the lower support, the upper support and the vehicle body 1 and the workbench surface 4, and ensuring the stability of the device.

[0082] The screws on the lifting device 2, the angle adjusting device 3 and the transverse movement adjusting device 8, as well as the handles at the front ends of the first adjusting screw 61 and the second adjusting screw 72, facilitate the construction personnel to rotate the screws to adjust the corresponding moving parts.

[0083] Embodiment 2:

[0084] In the embodiment, as Figures 5-7As shown, compared with Embodiment 1, the structures of the first clamping member 62 and the second clamping member 73 in Embodiment 2 are different from those of the first clamping member 62 and the second clamping member 73 in Embodiment 1. The first clamping member 62 and the second clamping member 73 in this embodiment both include a second moving bracket 731, a clamping plate adjusting screw 734, two second clamping plates 735, an adjusting nut 736, and a spring plate 737.

[0085] The second moving bracket 731 is a straight rod. The screw bracket 732 is welded to the second moving bracket 731 as a whole. The flared hole 733 on the second moving bracket 731 has a flared structure.

[0086] The diameter of the clamping plate adjusting screw 734 is smaller than the size of the narrowest part of the flared hole 733. The adjusting nut 736 is a wing nut, which is convenient for the staff to adjust the angle of the two second clamping plates 735 by hand without the need to use tools such as wrenches.

[0087] The spring plate 737 is used to keep the two second clamping plates 735 in an open state. The backs of the two second clamping plates 735 are in contact with the edge of the flared hole 733 for limiting.

[0088] The working mode of the present utility model:

[0089] When docking pipes:

[0090] Step 1: Push the device to the side of the docking port of the installed pipe 9. Rotate the handles of the lifting device 2 and the angle adjusting device 3 to lower the workbench surface 4 and the clamping device 5 below the bottom surface height of the pipe 9. Then rotate the handles of the fixed clamping device 6 and the movable clamping device 7 to separate the two groups of first clamping members 62 or the two groups of second clamping members 73.

[0091] Step 2: Push the device under the installed pipe 9 so that the docking port of the pipe 9 is located in the middle of the fixed clamping device 6 and the movable clamping device 7. The fixed clamping device 6 is located below the pipe 9, and the movable clamping device 7 is located outside the docking port of the pipe 9. Then rotate the handles of the lifting device 2 and the angle adjusting device 3 to raise the two groups of first clamping members 62 or the two groups of second clamping members 73 of the fixed clamping device 6 and the movable clamping device 7 to both sides of the pipe 9 and ensure that the workbench surface 4 is parallel to the pipe 9. Then rotate the handle of the fixed clamping device 6 to clamp the installed pipe 9 with the two groups of first clamping members 62 or the second clamping members 73 of the fixed clamping device 6, and then lock the universal wheels 12.

[0092] If the clamping members of the fixed clamping device 6 and the movable clamping device 7 are the second clamping members 73, the opening degree of the second clamping plates 735 can be adjusted by rotating the adjusting nut 736 according to the diameter of the pipe 9 before clamping the pipe 9 to adapt to pipes 9 of different diameters.

[0093] Step 3: The construction workers use the lifting equipment to lift the pipeline 9 to be installed, transport it to the side of the installed pipeline 9, rotate the pipeline 9 to be installed until it is parallel to the installed pipeline 9, then move one end of the pipeline 9 to be installed between the two groups of first clamping members 62 or the second clamping members 73 of the movable clamping device 7, and rotate the handle of the movable clamping device 7 to make the two groups of first clamping members 62 or the second clamping members 73 clamp the pipeline 9 to be installed.

[0094] Step 4: Rotate the handle of the transverse movement adjustment device 8, and drive the sliding plate 71 to move through the closing of the transverse movement adjustment device 8. The movement of the sliding plate 71 drives the pipeline 9 to be installed to approach the docking port of the installed pipeline 9.

[0095] Step 5: After the docking ports of the two pipelines 9 come into contact, install the pipeline 9 to be installed. If the docking port of the pipeline 9 is a flange, the construction workers use bolts to connect and fix the two flanges. If the docking port of the pipeline 9 is for welding, the construction workers use a welding machine to weld the docking ports of the two pipelines 9 together.

[0096] Step 6: After the pipeline 9 is connected, first rotate the handles of the fixed clamping device 6 and the movable clamping device 7 to separate the two groups of first clamping members 62 or the two groups of second clamping members 73 of the fixed clamping device 6 and the movable clamping device 7. After the clamping members release the pipeline 9, rotate the handles of the lifting device 2 and the angle adjustment device 3 to lower the workbench surface 4 and the clamping device 5 below the bottom surface height of the pipeline 9.

[0097] Step 7: Then move the device to the other end of the pipeline 9 and repeat the above steps 2-6 until the pipeline 9 is installed.
