Description

Technical Field

[0001] The utility model relates to the technical field of heating pipeline maintenance, in particular to a heating pipeline rapid maintenance device. Background Art

[0002] In modern society, central heating systems play a vital role in cities and industries, providing people with a warm and comfortable living and working environment. However, during long-term operation, heating pipes will inevitably be affected by various factors, such as pipe aging, corrosion, external force damage, thermal expansion and contraction caused by temperature changes, etc., resulting in damage, leakage and other problems.

[0003] The maintenance method of heating pipes is usually cumbersome. Maintenance personnel often need to stop the operation of the entire heating system first, and then cut, weld or replace parts of the pipes. In the heating system, the heating pipes are prone to damage, leakage and other problems due to long-term influence of factors such as thermal expansion and contraction, corrosion and external pressure. Effective plugging of the damaged parts is currently a more commonly used maintenance method. However, plugging is currently done by directly applying glue, plugging agents or welding to the cracks manually. During the whole process, the operator is suspended in the air, without a force support point. The weight of the equipment is directly supported by the operator, and it is very easy to shake during operation. The plugging agent or welding caused by shaking is prone to deviation on the smooth arc surface of the pipe, which increases the difficulty of leak repair, prolongs the time of leak repair, and reduces the efficiency of leak repair.

[0025] A limiting groove 6 is provided on the upper end surface of each locking seat 1, and the two limiting grooves 6 are connected, and a mounting seat 7 is slidably connected to the limiting groove 6. The limiting groove 6 includes a first arc groove and a second arc groove, and the first arc groove is provided on the upper end surface of the locking seat 1, and the second arc groove is provided in the first arc groove, and the distance between the two inner side walls of the second arc groove is greater than the distance between the two inner side walls of the first arc groove. The mounting seat 7 includes a first arc block and a second arc block, and the first arc block is slidably connected in the first arc groove, and the second arc block is slidably connected in the second arc groove. The upper end of the first arc block is fixedly connected with an arc mounting block, and the width of the arc mounting block is greater than the width of the first arc block, so as to prevent the mounting seat 7 from falling off the limiting groove 6 after the two locking seats 1 are installed, and ensure that the mounting seat 7 is stably stuck in the limiting groove 6 and drives the limiting ring 12 to rotate;

[0026] An extension component is obliquely arranged on the mounting seat 7, and the upper end of the extension component is fixedly connected with a base 11, the extension component includes a fixed screw 8, and the fixed screw 8 is obliquely arranged on the upper surface of the mounting seat 7, a movable screw 9 is slidably connected to the fixed screw 8, and the base 11 is fixedly connected to the upper end of the movable screw 9, a long groove is provided in the middle of the fixed screw 8, and the lower end of the movable screw 9 is located in the long groove, placement grooves are provided on both sides of the movable screw 9, and the upper end of the fixed screw 8 is located in the placement groove, the fixed screw 8 and the movable screw 9 limit each other to prevent the movable screw 9 from rotating with the rotation of the rotating frame 10, the fixed screw 8 and the movable screw 9 are commonly threadedly connected with the rotating frame 10, the rotating frame 10 includes two symmetrically arranged threaded sleeves 1002, and the threaded sleeve 1002 at the upper end is threadedly connected to the movable screw 9, and the threaded sleeve 1002 at the lower end is threadedly connected to the fixed screw 8, and the two threaded sleeves 1002 are commonly fixedly connected with a connecting frame 1001;

[0028] When the utility model is used, the two locking seats 1 are sleeved outside the heating pipe that needs to be repaired. After the sleeve is completed, the locking studs 4 are rotated to clamp the locking studs 4 in the two locking notches 3 (such as Figure 1As shown), the butterfly nut 5 is then rotated to make the butterfly nut 5 abut against the fixing seat 2 corresponding to the position, so as to fix and lock the two locking seats 1 to fix the device on the heating pipe; the end of the plugging device (such as a plugging agent cylinder, a welding device head, a sealant outlet) is then prevented from being on the limiting ring 12, and then the limiting ring 12 is driven to rotate by the plugging device to align the end of the plugging device with the damaged crack of the pipeline. If the distance between the end of the plugging device and the crack of the pipeline is large, the position of the limiting ring 12 can be adjusted by the extension component to ensure that the end of the plugging device can be aligned with the crack of the pipeline, and finally the crack is repaired by the plugging device (sealant, plugging agent or welding, etc.). When performing the repair, the plugging device, the limiting ring and the extension component can be used to drive the mounting seat 7 to move in the limiting groove 6, so as to process the cracks at different positions on the outer surface of the pipeline;

[0029] When the extension assembly is used to adjust the position of the limit ring 12, the rotating frame 10 is rotated. During the rotation of the rotating frame 10, the threaded sleeve 1002 rotates accordingly. The threaded sleeve 1002 is threadedly connected to the fixed screw 8 and the movable screw 9. Therefore, during the rotation, the distance between the rotating frame 10 and the mounting seat 7 changes, and the rotating frame 10 drives the movable screw 9 to move its position. The distance between the movable screw 9 and the mounting seat 7 also changes accordingly. Therefore, the distance between the limit ring 12 and the locking seat 1 changes, so that the position of the limit ring 12 can be adjusted.
