Description

Technical Field

[0001] The invention belongs to the technical field of pipeline overlap assembly, and in particular relates to an auxiliary bracket device for overlapping heating pipelines. Background Art

[0002] The outside of the heating pipe is usually equipped with an insulation mechanism. The purpose of the insulation is to reduce the heat loss of the heating pipe and its accessories, equipment, etc. to the surrounding environment. The function is to reduce the heat loss of the heating medium during the transportation process, save fuel, ensure the quality of heating, and meet the needs of users.

[0003] In the overlapping installation of heating pipes, because the heating pipes and the external insulation structure cause the pipes to become larger and heavier, the original ordinary brackets are inconvenient to use, so it is necessary to design an auxiliary bracket that meets the use of heating pipes for use: the heating pipe fixing bracket of the heating project described in the patent application with reference to the publication number CN215258229U includes a supporting connecting rod, a limiting hole and a movable sleeve ring, the inner part of the supporting connecting rod is penetrated and connected with the limiting hole, the surface of the supporting connecting rod is movably connected with the movable sleeve ring, the inner part of the movable sleeve ring is embedded and connected with the limiting bolt, and one side of the movable sleeve ring is fixedly connected with a lap plate, which improves the convenience of the device body. When fixing the pipe, the staff can use the adjustment mechanism to adjust the height and orientation of the device, which is suitable for the use of heating pipe fixing and has broad development prospects in the future;

[0004] In the use of the above technical solution, when two sections of the pipeline are connected, the heat pipe and the metal pipes in the external insulation structure are usually welded, so an extremely precise docking effect is required. If there is a deviation, it may affect the welding effect, and then affect the overlapping effect. At the same time, the above technical means can only adjust the installation position of the pipeline within a certain range on the ground. Some heating pipelines need to be below the ground, so it is difficult to achieve auxiliary support, pipe delivery and adjustment effects. In order to solve the above technical problems, an auxiliary bracket device for overlapping heating pipelines is now provided. Summary of the invention

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0044] An embodiment of the present invention provides an auxiliary support device for overlapping heating pipelines, including a main frame assembly 1 and a bracket assembly 2: several lifting mechanisms 5 are arranged on the outer wall of the main frame assembly 1, and a movable frame assembly 3 is connected to the outer wall of the main frame assembly 1 through the lifting mechanisms 5. An insertion frame assembly 4 is inserted into the inner wall of the movable frame assembly 3, and the bracket assembly 2 is arranged inside the inner wall of the insertion frame assembly 4;

[0045] Among them, the bracket assembly 2 includes a limit hydraulic cylinder 202 fixedly arranged on the inner wall of the insertion frame assembly 4. One end of the limit hydraulic cylinder 202 is fixedly connected to a limit bracket mechanism 201. The limit bracket mechanism 201 includes a bracket frame 2012 fixedly arranged on the limit hydraulic cylinder 202. A laser lamp 2013 is installed in the middle of one side of the bracket frame 2012.

A main remote control switch 2014 and a secondary remote control switch 2015 are symmetrically installed on the inner wall of the bracket frame 2012;

[0046] The inner wall of the bracket frame 2012 is in a cavity state. The limit bracket mechanism 201 further includes an inner corrugated soft pad 2011 fixedly arranged at the bottom;

[0047] Among them, the main mobile power supply 2016, the main remote control switch 2014 and the laser lamp 2013 are sequentially connected in series through wires; the secondary mobile power supply 2017, the secondary remote control switch 2015 and the laser lamp 2013 are sequentially connected in series through wires;

[0048] The number of the bracket assemblies 2 is multiple, and every four bracket assemblies 2 are symmetrically arranged up, down, left and right as a group.

[0049] It should be noted that in the existing technical means during use, when connecting two sections of pipelines, the metal pipes in the heating pipeline and the external insulation structure are usually welded, so extremely precise docking effects are required. If there are deviations, it may affect the welding effect and further affect the overlapping effect. At the same time, the above technical means can only adjust the installation position of the pipeline within a certain range on the ground. For some heating pipelines that need to be below the ground, it is difficult to achieve the effects of auxiliary support, pipe feeding and adjustment.

[0050] Specifically, in this embodiment, this solution mainly uses the settings and coordinated use of the main frame assembly 1, the bracket assembly 2, the lifting mechanism 5, the movable frame assembly 3, the insertion frame assembly 4 and the bottom row seat 6. During use: First, fix the bottom row seat 6 on both sides of the pipeline installation, and push the main frame 1011 to move to adjust the position of the front and rear main frame seat mechanisms 101 so as to overlap the pipelines. Then control the lifting of the positioning hydraulic cylinder 103 to position the positioning insert 102 so that the positioning insert 102 is inserted into the ground to complete the position fixation of the main frame assembly 1;

[0051] Then, the rack assembly 4 and the bracket assembly 2 are installed as needed, and the lifting motor is started and controlled to drive the lifting tooth plate 3011 and the movable lifting frame mechanism 301 to move up and down through the toothed disc, so as to adjust the overlapping position of the pipes in the bracket assembly 2, and the heating pipes to be overlapped and the insulation layer outside the pipes are placed between several bracket assemblies 2, and according to the lateral installation position of the heating pipes, the limiting hydraulic cylinder 202 is started and controlled to move the position of the limiting bracket mechanism 201, so that the four inner corrugated cushions 2011 around are tightly stuck to the outer wall of the insulation layer outside the pipe, and the pipe is clamped and fixed; when the two heating pipes to be overlapped and the insulation layer outside the pipes are fixed inside the limiting bracket mechanism 201 , the two ends of the heating pipe are fitted together, the main remote control switch 2014 or the auxiliary remote control switch 2015 is turned on by remote control to energize the laser lamp 2013, and the laser lamp 2013 of the limit bracket mechanism 201 above the pipes at both ends is compared to observe whether the laser rays on both sides overlap. When the pipes at both ends are aligned, the laser rays on both sides overlap. Conversely, when the laser rays on both sides do not overlap, it means that the pipes at both ends are not aligned. Then the position of the pipe is adjusted by controlling the limit hydraulic cylinder 202. When the pipes at both ends are aligned, welding is performed. After the welding of the internal heating pipe is completed, the insulation layer outside the pipe is moved, and the insulation layer of the pipe is docked, and the metal pipe outside the insulation layer is welded, so as to complete the docking connection of the heating pipe;

[0052] Among them, by starting and controlling the push hydraulic cylinder 702 to push the sliding seat block 703 outward, and starting and controlling the direction adjustment motor 704, the positions of the rotating bracket 705 and the transmission roller 706 are rotated and adjusted. When the outer wall of the transmission roller 706 fits the outer wall of the heating pipe to be overlapped, the transmission motor 707 is started and controlled to drive the transmission roller 706 to rotate, thereby moving the heating pipe, so that the two sections of the pipe to be overlapped are slowly approached after cleaning, and then the inner heating pipe and the outer metal pipe of the insulation layer are circle welded using welding equipment;

[0053] After the welding machine equipment cooperates with the stretching assembly 7 to weld the inner heating pipe, the first nozzle 804 is pulled out and the switch of the first storage tank seat 801 is started to rotate and spray the rust preventive agent on the outer wall of the heating pipe. Then, when the stretching assembly 7 pulls the heating insulation layer to make the insulation layers at both ends docked, the second nozzle 806 is pulled to align with the insulation layer docking at both ends, and the push rod in the second storage tank 805 is opened to push the glue out for adhesion; the stretching assembly 7 then pulls the outer metal pipe of the heating insulation layer to make the outer metal pipes at both ends docked, and after welding with the welding machine equipment, the first nozzle 804 is pulled out and the switch of the first storage tank seat 801 is started to rotate and spray the rust preventive agent on the outer wall of the outer metal pipe;

[0054] Finally, according to the pipeline laying requirements, when all the pipelines are overlapped, the movable frame assembly 3 is controlled by the plug-in frame assembly 4 to move and lay the pipeline. When the pipeline needs to be buried, the lower socket 402 and the bracket assembly 2 attached to the lower socket 402 are taken out, and after the docked pipeline is placed, the heating system is turned on to check whether the pipeline can be used normally, and finally fill the soil to complete the laying.

[0055] In this embodiment, through the arrangement of the bracket assembly 2, during use, the plug-in assembly 4 and the bracket assembly 2 are installed as needed, the heating pipes to be overlapped and the insulation layer outside the pipes are placed between several bracket assemblies 2, and according to the lateral installation position of the heating pipes, the limiting hydraulic cylinder 202 is started and controlled to move the position of the limiting bracket mechanism 201, so that the four inner corrugated cushions 2011 around are tightly stuck to the outer wall of the insulation layer outside the pipe, and the pipe is clamped and fixed; when the two heating pipes to be overlapped and the insulation layer outside the pipes are fixed inside the limiting bracket mechanism 201, the two end ports of the heating pipes are fitted, and the main remote control switch 2014 or the auxiliary remote control switch 2015 is turned on by remote control to turn on the laser light 2013 After power is turned on, the laser lights 2013 of the limiting bracket mechanism 201 above the pipes at both ends are compared to see whether the laser beams on both sides overlap. When the pipes at both ends are aligned, the laser beams on both sides overlap. Otherwise, when the laser beams on both sides do not overlap, the pipes at both ends are not aligned. Then the position of the pipes is adjusted by controlling the limiting hydraulic cylinder 202. When the pipes at both ends are aligned, welding is performed.
