Description

Technical Field

[0001] This utility model relates to the field of steel-jacketed insulated pipe technology, specifically an auxiliary device for installing steel-jacketed insulated pipes. Background Technology

[0002] With the continuous improvement of heating equipment, the installation of heating equipment has greatly increased. Steam pipes are a common component in heating equipment, which play a role in sealing and transporting steam, and also use insulation methods to reduce heat loss.

[0003] The invention patent with publication number CN113187958B discloses a steel-jacketed steam insulation pipe, including an outer cylinder and an inner cylinder. The inner cylinder is inserted into the outer cylinder. Concentric rings are symmetrically arranged at both ends of the outer cylinder, and the outer cylinder is fixedly connected to the inner cylinder through the rings. Three linkage regulators are evenly arranged between the outer and inner cylinders, and the ends of the regulators are connected to the rings. Rotary support mechanisms are equidistantly installed on the outer wall of the inner cylinder at the corresponding positions of the regulators. Three fastening mechanisms are equidistantly installed in the middle of the outer cylinder, and the fastening mechanisms are connected to the inner cylinder. This steel-jacketed steam insulation pipe, through the linkage adjustment of the regulators, causes the support mechanisms to rotate and form multi-point support with the inner wall of the outer cylinder. The fastening mechanisms, together with the rotation of the support mechanisms, evenly pull and position the middle of the inner cylinder, improving the support strength in the middle of the gap between the outer and inner cylinders and improving the deformation resistance of the device.

[0004] During the assembly of existing steel-jacketed insulated pipes, one end of the inner steel pipe needs to be lifted by a crane. When pushing the inner steel pipe into the inner cavity of the steel bend, the inner steel pipe is prone to swinging inside the outer steel pipe, causing collisions between the inner and outer steel pipes and damaging the insulation layer. This not only makes installation difficult but also seriously affects installation efficiency. To solve the above problems, this application proposes an auxiliary device for the installation of steel-jacketed insulated pipes. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] To address the technical problems existing in the background art, this utility model proposes an auxiliary device for installing steel-jacketed steel insulation pipes. During use, a moving trolley guides the end of the inner steel pipe, while a conveyor belt provides forward power to the inner steel pipe, enabling the inner steel pipe to be quickly installed into the outer steel pipe. This reduces the assembly difficulty of the steel-jacketed steel insulation pipe and improves assembly efficiency, thereby solving the problems mentioned in the background art.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides an auxiliary device for installing steel-jacketed insulated pipes, including an inner steel pipe and an outer steel pipe. The outer steel pipe is sleeved on the surface of the inner steel pipe. A bottom support plate is movably installed at one end of the outer steel pipe. Side support plates are rotatably connected to both sides of the bottom support plate. A bottom conveyor belt is installed in the inner cavity of the bottom support plate, and a side conveyor belt is installed in the inner cavity of each side support plate.

[0009] A limit plate is movably installed at the end of the outer steel tube away from the bottom support plate;

[0010] A locking ring is movably fitted at the end of the inner steel tube, and a telescopic support is welded to the bottom of the locking ring. A moving trolley is connected to the bottom of the telescopic support, and the moving trolley is located at the bottom of the inner cavity.

[0011] Preferably, a No. 1 clamp is fixedly welded to the end of the bottom support plate, and a No. 2 clamp is fixedly welded to the end of the limiting plate. The bottom support plate and the limiting plate are clamped to the outer steel tube by the No. 1 clamp and the No. 2 clamp, respectively.

[0012] Preferably, both the bottom conveyor belt and the side conveyor belt have anti-slip grooves on their surfaces.

[0013] Preferably, a rotating swing arm is rotatably connected to both sides of the bottom support plate, and an adjustment groove is provided on the lower surface of the side support plate, with the rotating swing arm inserted into the adjustment groove.

[0014] Preferably, the locking ring surface has threaded holes, and the threaded holes are equidistantly arranged on the locking ring surface.

[0015] Preferably, each of the threaded holes is threaded with an adjusting screw, and each adjusting screw is rotatably connected to a rotating clamp.

[0016] Preferably, telescopic cross arms are welded to the middle of both sides of the locking ring, and guide wheels are rotatably provided at the ends of the telescopic cross arms, with the guide wheels abutting against the inner wall of the outer steel tube.

[0017] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0018] 1. In this utility model, the locking ring clamps the inner steel tube and, in conjunction with the moving trolley, guides and supports the end of the inner steel tube. The insulation material covering the surface of the inner steel tube abuts against the surfaces of the bottom conveyor belt and the side conveyor belt.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0028] like Figure 1-5As shown, the present invention proposes an auxiliary device for installing steel-jacketed steel insulation pipe, including an inner steel pipe 1 and an outer steel pipe 2. The outer steel pipe 2 is sleeved on the surface of the inner steel pipe 1. A bottom support plate 3 is movably installed at one end of the outer steel pipe 2. Side support plates 4 are rotatably connected to both sides of the bottom support plate 3. A bottom conveyor belt 6 is installed in the inner cavity of the bottom support plate 3. Side conveyor belts 7 are installed in the inner cavities of the side support plates 4.

[0029] A limiting plate 9 is movably installed at the end of the outer steel tube 2 away from the bottom support plate 3;

[0030] The steel inner tube 1 is movably fitted with a locking ring 11 at one end. A telescopic support column 12 is welded to the bottom of the locking ring 11. A moving trolley 13 is connected to the bottom of the telescopic support column 12. The moving trolley 13 is located at the bottom of the inner cavity.

[0031] It should be noted that the end of the inner steel tube 1 is inserted into the locking ring 11. By rotating the adjusting screw 14, the adjusting screw 14 pushes the rotating clamp 15 against the surface of the inner steel tube 1 under the action of the surface thread, which can clamp the inner steel tube 1. The length of the telescopic support 12 and the telescopic cross arm 16 is adjusted so that the center of the inner steel tube 1 coincides with that of the outer steel tube 2. The bottom support plate 3 and the limiting plate 9 can be clamped at both ends of the outer steel tube 2 by the first clamp 5 and the second clamp 10, respectively. The insulation material covering the surface of the inner steel tube 1 abuts against the surface of the bottom conveyor belt 6 and the side conveyor belt 7. Under the action of surface friction, the bottom conveyor belt 6 and the side conveyor belt 7 can push the inner steel tube 1 forward. In combination with the moving trolley 13, the inner steel tube 1 can be quickly pushed into the outer steel tube 2, which can improve the assembly efficiency of the inner steel tube 1 and the outer steel tube 2.

[0032] In this embodiment, as Figure 4 and Figure 5 As shown, a first clamp 5 is fixedly welded to the end of the bottom support plate 3, and a second clamp 10 is fixedly welded to the end of the limiting plate 9. The bottom support plate 3 and the limiting plate 9 are clamped to the outer steel tube 2 by the first clamp 5 and the second clamp 10, respectively.

[0033] It should be noted that the bottom support plate 3 and the limiting plate 9 can be quickly installed using clamp 5 and clamp 10.

[0034] In this embodiment, as Figure 4 As shown, anti-slip grooves 8 are provided on the surfaces of the bottom conveyor belt 6 and the side conveyor belt 7.

[0035] It should be noted that the anti-slip groove 8 can increase the friction between the bottom conveyor belt 6 and the side conveyor belt 7 and the insulation layer.

[0036] In this embodiment, as Figure 4As shown, both sides of the bottom support plate 3 are rotatably connected to rotating swing arms 18, and the lower surface of the side support plate 4 is provided with adjustment grooves 19, and the rotating swing arms 18 are inserted into the adjustment grooves 19.

[0037] It should be noted that the bottom of the side support plate 4 is supported by the rotating swing arm 18. By selecting different adjustment grooves 19, the angle of the side support plate 4 can be adjusted so that the side conveyor belt 7 can better contact the insulation layer, so as to meet the auxiliary assembly of steel pipes of different diameters.

[0038] In this embodiment, as Figure 3 As shown, the locking ring 11 has threaded holes on its surface, and the threaded holes are equidistantly arranged on the surface of the locking ring 11. Each threaded hole is threaded with an adjusting screw 14, and each adjusting screw 14 is rotatably connected with a rotating clamp 15.

[0039] It should be noted that rotating the adjusting screw 14 causes the adjusting screw 14 to push the rotating clamp 15 against the surface of the steel inner tube 1 under the action of the surface thread, which can clamp the steel inner tube 1.

[0040] In this embodiment, as Figure 3 As shown, telescopic cross arms 16 are welded to the middle of both sides of the locking ring 11, and guide wheels 17 are rotatably provided at the ends of the telescopic cross arms 16, with the guide wheels 17 abutting against the inner wall of the steel outer tube 2.

[0041] It should be noted that by controlling the length of the telescopic cross arm 16, the guide wheel 17 is made to abut against the inner wall of the outer steel tube 2, so as to ensure that the moving trolley 13 moves in a straight line inside the outer steel tube 2.

[0042] The working principle and usage process of this utility model: The end of the inner steel tube 1 is inserted into the locking ring 11. Rotating the adjusting screw 14 causes the adjusting screw 14 to push the rotating clamp 15 against the surface of the inner steel tube 1 under the action of the surface thread, thus clamping the inner steel tube 1. Adjusting the lengths of the telescopic support column 12 and the telescopic cross arm 16 makes the center of the inner steel tube 1 coincide with that of the outer steel tube 2. The bottom support plate 3 and the limiting plate 9 can be clamped at both ends of the outer steel tube 2 respectively by clamp 5 and clamp 10. The insulation material covering the surface of the inner steel tube 1 abuts against the surfaces of the bottom conveyor belt 6 and the side conveyor belt 7. The bottom conveyor belt 6 and the side conveyor belt 7... The surface friction force can push the inner steel tube 1 forward, and in conjunction with the moving trolley 13, it can quickly push the inner steel tube 1 into the outer steel tube 2, which can improve the assembly efficiency of the inner steel tube 1 and the outer steel tube 2. After the moving trolley 13 moves from the outer steel tube 2, it lands on the limiting plate 9. The limiting plate 9 can limit the movement of the moving trolley 13. The side support plate 4 is rotatably connected to the bottom support plate 3. The bottom of the side support plate 4 is supported by the rotating swing arm 18. By selecting different adjustment grooves 19, the angle of the side support plate 4 can be adjusted so that the side conveyor belt 7 can better contact the insulation layer, so as to meet the auxiliary assembly of steel pipes of different diameters.

[0043] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
