Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation sleeves, in particular to a plug-in thermal insulation sleeve. Background Art

[0002] Steam insulation pipes often adopt a double-layer pipe structure. In large steam transmission pipelines, the internal steam pipes need to be supported and connected with the outer pipe. Since the outer layer of the existing steam pipe is a complete round pipe, the support mechanism is difficult to install or weld, and supporting components such as pipe supports cannot be installed or welded.

[0003] The search application number 202321087520.1 discloses a plug-in steam direct-buried insulated pipe. The outer sleeve and the port connecting pipe are spliced ​​together through the mutual adsorption of the first magnetic ring and the second magnetic ring. At this time, the working pipe will be protected inside the outer sleeve and the port connecting pipe. Through the coordination of the outer sleeve and the port connecting pipe, the airtightness and integrity of the outer sleeve are improved, and it is convenient to weld the fixing frame inside the pipe.

[0004] However, during the implementation of this solution, since the plug-in part is fixed on the port connecting pipe and the weight of the insulation pipe is large, a hoisting method is often used to assist the installation of the insulation pipe during installation. However, since the insulation pipe is installed by hoisting, the insulation pipe lacks fixation. During hoisting, the insulation pipe is prone to swing or one end is lifted up, and the two insulation pipes are misaligned with each other. Since the plug-in part of the insulation pipe and the port connecting pipe are integrally formed and fixed to each other, and the connection strength between the plug-in part and the port connecting pipe is low, the plug-in part is easily bent or even broken when the insulation pipe is lifted up or misaligned, thereby affecting the subsequent connection of the device and even causing the port connecting pipe to be scrapped. Therefore, a product is proposed that can not cause damage to the insulation pipes when the insulation pipes are connected, even if the insulation pipes are misaligned with each other, thereby ensuring the integrity of the insulation pipe structure and reducing the scrap rate of the insulation pipes during installation.

DETAILED DESCRIPTION

[0023] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0024] See also Figure 1-5The utility model provides a technical solution: a plug-in thermal insulation sleeve, including an outer sleeve 1, a working tube 4 is arranged inside the outer sleeve 1, the working tube 4 protrudes from one end of the outer sleeve 1, an annular groove 8 is opened at one end of the outer sleeve 1, and a connecting ring 2 is slidably connected to the end of the outer sleeve 1 without the annular groove 8, the connecting ring 2 is adapted to the annular groove 8, the end of the connecting ring 2 away from the outer sleeve 1 is fixedly connected to the first magnet 3, the inner wall of the annular groove 8 is fixedly connected to the second magnet 14, and the movable plate 13 and the first magnet 3 attract each other, so that the staff can insert the connecting ring 2 on one outer sleeve 1 into the annular groove 8 on one outer sleeve 1 to complete the connection between the two outer sleeves 1, thereby improving the efficiency of connecting the two outer sleeves 1.

[0025] Furthermore, an end of the connecting ring 2 close to the outer sleeve 1 is fixedly connected to a slide plate 12, and the surface of the slide plate 12 is slidably connected to the inside of the outer sleeve 1. Second springs 11 are fixedly connected to both sides of the slide plate 12, and the ends of the two second springs 11 away from the slide plate 12 are fixedly connected to the inside of the outer sleeve 1. Therefore, through the provision of the second spring 11, a certain sliding force can be provided for the resetting of the outer sleeve 1 and the connecting ring 2 when the outer sleeve 1 and the connecting ring 2 are misaligned with each other. Furthermore, through the provision of the slide plate 12 and the second spring 11, a certain space is provided for the mutual sliding between the connecting ring 2 and the outer sleeve 1, thereby avoiding the situation that when the two outer sleeves 1 are docked, the lifting of the other outer sleeve 1 by the lifting equipment causes the two outer sleeves 1 to be misaligned, resulting in the breaking of the connecting ring 2, which causes the outer sleeve 1 to be scrapped and unusable, thereby improving the use effect of the device and having a high promotion value.

[0026] The surface of the working tube 4 is provided with an insulation layer 18, which can insulate the interior of the working tube 4. Four support plates 7 arranged equidistantly in a circle are fixedly connected to the surface of the working tube 4. Multiple groups of support plates 7 are provided on the surface of the working tube 4. The end of the support plate 7 away from the working tube 4 is fixedly connected to the inner wall of the outer sleeve 1. Therefore, through the setting of the support plate 7, the working tube 4 can be stably erected in the outer sleeve 1, ensuring the working stability of the outer sleeve 1. The surface of the working tube 4 is slidably connected with a moving tube 10. The four support plates 7 near the open end of the annular groove 8 all penetrate the moving tube 10 and are slidably connected to the interior of the moving tube 10. The surface of the support plate 7 is fixedly connected with a first spring 9. The end of the first spring 9 away from the support plate 7 is fixedly connected to the interior of the moving tube 10 to limit the position of the moving tube 10, thereby avoiding the situation where the moving tube 10 slides freely on the surface of the working tube 4, which facilitates the subsequent connection of the two outer sleeves 1.

[0027] The surfaces of the four support plates 7 near the open end of the annular groove 8 are all slidably connected with a top plate 6, and two fixed plates 17 are fixedly connected to the side of the top plate 6 near the moving tube 10. The surface of the moving tube 10 is also fixedly connected with a fixed plate 17, and an inclined connecting rod 16 is rotatably connected between the two fixed plates 17. The surface of the moving tube 10 is fixedly connected with a moving plate 13, and the end of the moving plate 13 away from the moving tube 10 penetrates into the interior of the annular groove 8, and the surface of the moving plate 13 is slidably connected to the interior of the outer sleeve 1, and the surface of the second magnet 14 is provided with a hidden groove 15, and the surface of the moving plate 13 is slidably connected to the inner wall of the hidden groove 15, so that the moving plate 13 can be hidden in the hidden groove 15 through the setting of the hidden groove 15, thereby avoiding the moving plate 13 protruding from the surface of the second magnet 14 to affect the attachment strength between the first magnet 3 and the second magnet 14, thereby ensuring the stability of the docking between the two outer sleeves 1.

[0028] The surface of the top plate 6 is inlaid with balls 5, and the setting of the balls 5 reduces the friction between the top plate 6 and the inner wall of the outer sleeve 1, thereby avoiding the situation where the friction between the top plate 6 and the inner wall of the outer sleeve 1 is large, thereby increasing the difficulty of connecting the two outer sleeves 1, and further improving the use effect of the device.

[0029] Specifically, when the two outer sleeves 1 are docked, the connecting ring 2 of one outer sleeve 1 is inserted into the annular groove 8 of the other outer sleeve 1, and then the top plate 6 is also located inside the other outer sleeve 1. As the connecting ring 2 is inserted, the connecting ring 2 pushes the moving plate 13, thereby driving the moving tube 10 to slide on the surface of the working tube 4 and compressing the first spring 9. The movement of the moving tube 10 drives the fixed plate 17 on the moving tube 10 to move, so that the fixed plate 17 on the moving tube 10 and the fixed plate 17 on the top plate 6 gradually move vertically. The top plate 6 is straight, and the top plate 6 cannot move backward due to the obstruction of the moving tube 10, so that the connecting rod 16 gradually tends to a vertical state from an inclined state, and then the top plate 6 is pushed up, so that the top plate 6 gradually fits with the inner walls of the two outer sleeves 1, and then the two outer sleeves 1 are driven to move relative to each other, so that the two outer sleeves 1 gradually become concentric and are in the same straight line, and the docking between the two outer sleeves 1 is completed, so that the device can ensure the concentricity of the two outer sleeves 1 during the connection process, facilitate the docking of the two outer sleeves 1, improve the use effect of the device, and have a high promotion value.

[0030] Working principle: insert the connecting ring 2 into the annular groove 8 of the other outer sleeve 1, the connecting ring 2 pushes the moving plate 13, thereby driving the moving tube 10 to slide on the surface of the working tube 4, and compressing the first spring 9. The movement of the moving tube 10 drives the fixed plate 17 on the moving tube 10 to move, so that the fixed plate 17 on the moving tube 10 is gradually perpendicular to the fixed plate 17 on the top plate 6, and the top plate 6 cannot move backward due to the obstruction of the moving tube 10, so that the connecting rod 16 gradually tends to be vertical from an inclined state, and then the top plate 6 is pushed, so that the top plate 6 gradually fits with the inner walls of the two outer sleeves 1, and the two outer sleeves 1 are gradually concentric.

[0031] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
