Description

Technical Field

[0001] This utility model relates to the field of tube-insulating slides for steel-clad steel insulated pipes, specifically a tube-insulating assembly device for steel-clad steel insulated pipes. Background Technology

[0002] Steel-jacketed insulated pipe is an insulated pipe consisting of an inner pipe, an outer pipe, and an insulation layer. After the insulation layer is installed on the outer wall of the inner pipe, the inner pipe with the insulation layer installed needs to be inserted into the outer pipe. In the existing technology, a sliding frame mechanism is generally installed at both ends of the inner pipe to assist the inner pipe in being inserted into the outer pipe.

[0003] In the existing technology, after the pipe is installed, a steel frame is welded between the inner and outer pipes, and then the sliding frame mechanism is disassembled. Since the sliding frame mechanism is limited by the outer pipe at this time, the clamp ring still abuts against the outer circumference of the inner pipe after the bolts and nuts are removed, which makes disassembly more difficult. Utility Model Content

[0004] The purpose of this utility model is to provide a steel-clad steel insulation pipe installation device in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel-clad steel insulation pipe assembly device, comprising an inner pipe with an external insulation layer, wherein the insulation layer does not cover the outer walls of both ends of the inner pipe, and the outer walls of both ends of the inner pipe are exposed, and a sliding frame mechanism is installed on the exposed outer walls of both ends of the inner pipe, and an adjustment mechanism is installed on the support of the sliding frame mechanism.

[0006] As a further embodiment of this utility model: the sliding frame mechanism includes two clamping rings, which are spliced ​​together and clamped to the exposed exterior of both ends of the inner tube. The mating ends of the two clamping rings are bent into fixing ears. Multiple sets of brackets are welded at equal intervals on the outer periphery of the clamping rings, and a pulley is rotatably installed on the inner side of one set of brackets.

[0007] As a further embodiment of this utility model: the adjustment mechanism includes a slide groove opened along the length direction of the support, a slider is slidably installed on the inner wall of the slide groove, and the slider is rotatably connected to the rotating shafts at both ends of the pulley through bearings.

[0008] As a further embodiment of this utility model: the adjustment mechanism further includes a support base welded to the outside of the bracket and aligned with the slide groove, the support base having an adjustment bolt internally threaded, and one end of the adjustment bolt having a support plate fixedly installed to support the horizontal part of the slider.

[0009] As a further improvement of this utility model, the two relatively aligned fixing ears are fixedly connected by bolts and nuts.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. By setting an adjustment mechanism, when disassembling the sliding frame mechanism, the pulley will no longer be in contact with the inner wall of the outer tube by rotating the adjustment mechanism, thus making disassembly easier. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 In this embodiment of the utility model, a steel-clad steel insulation pipe assembly device includes an inner pipe 1 with an external insulation layer 2. The insulation layer 2 does not cover the outer walls of both ends of the inner pipe 1, leaving the outer walls of both ends of the inner pipe 1 exposed. A sliding frame mechanism is installed on the exposed outer walls of both ends of the inner pipe 1, and an adjustment mechanism is installed on the support 6 of the sliding frame mechanism.

[0018] In this embodiment: During the pipe insertion operation, a sliding frame mechanism is installed at the exposed portions of the outer wall of the inner tube 1. Then, an insulation layer 2 is installed on the outer periphery of the inner tube 1. After the insulation layer 2 is installed, the inner tube 1 wrapped with the insulation layer 2 can be inserted into the outer tube 3 through the sliding frame mechanism. During the process of the inner tube 1 being inserted into the outer tube 3, the sliding frame mechanism can slide relative to the inner wall of the outer tube 3, supporting the inner tube 1 with the insulation layer 2 on the outer wall, and avoiding the insulation layer 2 from being squeezed against the inner wall of the outer tube 3, which would cause friction damage to the insulation layer 2.

[0019] Please refer to this carefully. Figure 1 and Figure 2 The sliding frame mechanism includes two clamping rings 4. The two clamping rings 4 in the spliced ​​state are clamped to the exposed exterior of both ends of the inner tube 1. The mating ends of the two clamping rings 4 are bent into fixed ears 5. Multiple sets of brackets 6 are welded at equal intervals on the outer periphery of the clamping rings 4. A pulley 7 is rotatably installed on the inner side of one set of brackets 6.

[0020] In this embodiment: When installing the sliding frame mechanism, first, the two clamping rings 4 are fitted onto the two ends of the outer wall of the inner tube 1, and the fixing ears 5 at both ends of the two clamping rings 4 are aligned. Then, bolts and nuts are used to tighten the aligned fixing ears 5. After the bolts and nuts are fixed, the two clamping rings 4 are tightly clamped to the ends of the outer wall of the inner tube 1. Then, when performing the tube insertion operation, the fixed sliding frame mechanism can effectively reduce the friction during the tube insertion operation and can provide support for the inner tube 1. During the tube insertion process, the pulley 7 rotates under force, which can effectively reduce the friction and ensure the smooth progress of tube insertion.

[0021] Please refer to this carefully. Figure 3 The adjustment mechanism includes a slide groove 9 opened along the length of the support 6. A slider 10 is slidably installed on the inner wall of the slide groove 9. The slider 10 is rotatably connected to the rotating shafts 8 at both ends of the pulley 7 through bearings. The adjustment mechanism also includes a support base 11 welded to the outside of the support 6 and aligned with the slide groove 9. An adjustment bolt 12 is threadedly connected to the inside of the support base 11. A support plate 13 is fixedly installed at one end of the adjustment bolt 12 to support the horizontal plate of the slider 10.

[0022] In this embodiment: After the pipe is inserted, a steel frame is welded between the exposed end of the outer wall of the inner pipe 1 and the inner wall of the outer pipe 3. The steel frame should be located between the sliding frame mechanism and the insulation layer 2. At this time, the bolts and studs on the connecting fixing lug 5 are removed. Since the inner wall of the outer pipe 3 drives the sliding frame mechanism to limit the movement, the inner wall of the clamp ring 4 is still against the outer wall of the inner pipe 1. A large pulling force is required to remove the clamp ring 4.

[0023] Therefore, during disassembly, a tool is used to connect with the end of the adjusting bolt 12 and rotate the adjusting bolt 12. The rotating adjusting bolt 12 rotates downward relative to the slider 10 and moves. At this time, the adjusting bolt 12 drives the support plate 13 to move downward. At this time, the slider 10 moves downward along the slide groove 9, realizing the inward retraction adjustment of the pulley 7, which no longer abuts against the inner wall of the outer tube 3, thus facilitating the disassembly of the clamp ring 4.

[0024] Please refer to this carefully. Figure 1 The two relatively aligned fixed ears 5 are fixedly connected by bolts and nuts.

[0025] In this embodiment: the bolt and nut can be tightened by fixing the two clamping rings 4 with the fixing lug 5, and the two clamping rings 4 can be disassembled by removing the bolt and nut.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
