Description

Technical Field

[0001] This utility model relates to the field of thermal pipeline technology, and more specifically to a device for connecting thermal pipelines. Background Technology

[0002] Heating pipelines (also known as heating networks or heating pipes) are a core component of centralized heating systems. They are specifically designed to transport heat media such as steam or hot water, transferring heat energy generated by heat sources such as boilers, direct-fired engine rooms, or heating centers to building entrances or indoor heating equipment (such as heating and air conditioning). Their core task is to achieve efficient heat energy transfer to meet the needs of industrial production and residential life.

[0003] When installing heating pipes, it is usually necessary to connect two pipes by welding their ends together. After welding, connecting equipment is needed to limit or support the two pipes to ensure their stability. Lifting is a common construction step in the installation of heating pipes. However, existing connecting equipment is difficult to adjust the position of the support and limit when supporting the lifted pipes, and needs to be improved. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for connecting thermal pipelines to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a device for connecting thermal pipelines, comprising an upper connecting semicircular cover and a lower connecting semicircular cover. The top of the lower connecting semicircular cover overlaps the bottom of the upper connecting semicircular cover. An mounting plate is provided above the upper connecting semicircular cover. Two screws are fixedly installed at the bottom of the mounting plate. A support plate is provided below the mounting plate. The interior of the support plate is movably disposed on the outer wall of the two screws. Fixing frames are fixedly connected to the four corners of the bottom of the support plate. The bottom of the fixing frames is fixedly connected to the top of the upper connecting semicircular cover. A fixing nut is fixedly connected to both sides of the upper and lower connecting semicircular covers. There are six fixing nuts. Each of the six fixing nuts has a positioning bolt threaded inside. The six fixing nuts are divided into two groups, with three fixing nuts in each group. The two groups of fixing nuts are evenly distributed on both sides of the upper and lower connecting semicircular covers.

[0006] Furthermore, both screws have an upper nut and a lower nut threadedly connected to their outer walls. The top of the lower nut overlaps the bottom of the support plate, and the bottom of the upper nut overlaps the top of the support plate.

[0007] Furthermore, guide rods are fixedly connected to both sides of the bottom of the mounting plate, and there are two guide rods. The two sides inside the support plate are slidably connected to the outer walls of the two guide rods.

[0008] Furthermore, the top of the mounting plate has four mounting openings, which are distributed at the four corners of the top of the mounting plate.

[0009] Furthermore, three upper assembly nuts are fixedly installed on the center of the front side and both sides of the back side of the upper docking semicircular cover, and three lower assembly nuts are fixedly installed on the center of the front side and both sides of the back side of the lower docking semicircular cover.

[0010] Furthermore, the lower assembly nut is located directly below the upper assembly nut, and assembly bolts are threadedly connected between the three lower assembly nuts and the three upper assembly nuts.

[0011] Furthermore, observation slots are provided in the middle of both the upper and lower docking semicircular covers.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model employs a combination of a lower connecting semicircular cover, a mounting plate, screws, an upper nut, a lower nut, a support plate, a fixing frame, and a guide rod. By spirally moving the lower nut, the support plate can be moved along the outer walls of the two screws. The cooperation of the upper and lower nuts facilitates the fixing of the support plate onto the outer walls of the two screws. When the support plate moves, the positions of the upper and lower connecting semicircular covers can be adjusted via the fixing frame, thereby facilitating the adjustment of the support and limiting positions of the upper and lower connecting semicircular covers for the pipeline.

[0014] 2. This utility model uses three assembly bolts, a lower assembly nut, and an upper assembly nut to facilitate the assembly of the upper and lower connecting semicircular covers together, thereby limiting the connection point at the ends of the two thermal pipes. Furthermore, through the cooperation of multiple No. 1 fixing nuts and positioning bolts, the positions of multiple positioning bolts can be adjusted so that one end of each positioning bolt abuts against the outer wall of the two thermal pipes, further limiting the connection between the two pipes and maintaining their stability.

Detailed Implementation

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The device for connecting thermal pipelines involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1:

[0022] like Figure 1-4 As shown, a device for connecting thermal pipelines includes an upper connecting semicircular cover 1 and a lower connecting semicircular cover 2. The top of the lower connecting semicircular cover 2 overlaps the bottom of the upper connecting semicircular cover 1. Six fixing nuts 4 are fixedly connected to both sides of the upper and lower connecting semicircular covers 1 and 2. Each of the six fixing nuts 4 has a positioning bolt 5 threaded inside. The six fixing nuts 4 are divided into two groups of three, with the two groups of fixing nuts 4 evenly distributed on the upper connecting semicircular cover. On both sides of cover 1 and lower connecting semicircular cover 2, upper assembly nuts 8 are fixedly installed on the center of the front and both sides of the back of upper connecting semicircular cover 1. There are three upper assembly nuts 8. On both sides of the front and back of lower connecting semicircular cover 2, lower assembly nuts 7 are fixedly installed. There are three lower assembly nuts 7. The lower assembly nuts 7 are located directly below the upper assembly nuts 8. Assembly bolts 6 are threadedly connected between the three lower assembly nuts 7 and the three upper assembly nuts 8. Observation slots 9 are opened in the center of both upper connecting semicircular cover 1 and lower connecting semicircular cover 2.

[0023] In this embodiment, by spirally installing three assembly bolts 6 inside the space between three lower assembly nuts 7 and three upper assembly nuts 8, the upper docking semicircular cover 1 and the lower docking semicircular cover 2 can be assembled together, thereby limiting the docking point of the two thermal pipes and positioning the observation slots 9 of the upper docking semicircular cover 1 and the lower docking semicircular cover 2 at the docking point of the two thermal pipes. Then, by spirally moving multiple positioning bolts 5, one end of the multiple positioning bolts 5 abuts against the outer wall of the two thermal pipes, thereby further limiting the distance between the two pipes and facilitating the maintenance of the stability between the two pipes. The setting of the observation slots 9 allows the staff to easily observe most of the space inside the thermal pipe docking point. If a leak or other fault occurs at the thermal pipe docking point, timely repair is convenient.

[0024] Example 2:

[0025] like Figure 1-4 As shown, an mounting plate 3 is provided above the upper abutment semicircular cover 1. Two screws 31 are fixedly installed at the bottom of the mounting plate 3. A support plate 34 is provided below the mounting plate 3. The interior of the support plate 34 is movably set on the outer wall of the two screws 31. Fixing brackets 35 are fixedly connected to the four corners of the bottom of the support plate 34. The bottom of the fixing brackets 35 is fixedly connected to the top of the upper abutment semicircular cover 1. The outer walls of the two screws 31 are threaded with upper nuts 32 and lower nuts 33. The top of the lower nut 33 overlaps the bottom of the support plate 34, and the bottom of the upper nut 32 overlaps the top of the support plate 34. Guide rods 36 are fixedly connected to both sides of the bottom of the mounting plate 3. There are two guide rods 36. The two sides of the interior of the support plate 34 are slidably connected to the outer walls of the two guide rods 36. Four mounting holes 37 are opened on the top of the mounting plate 3. The four mounting holes 37 are distributed at the four corners of the top of the mounting plate 3.

[0026] In this embodiment, the mounting port 37 allows the mounting plate 3 to be fixedly installed in a designated position using bolts. By spirally moving the lower nut 33 below the two screws 31, the support plate 34 can move on the outer walls of the two screws 31 and the two guide rods 36. The two guide rods 36 provide vertical guidance to both sides of the support plate 34. The support plate 34 is simultaneously adjusted via the fixing bracket 35 to adjust the positions of the upper and lower connecting semicircular covers 1 and 2, thereby facilitating the adjustment of the support and limiting positions of the upper and lower connecting semicircular covers 1 and 2 for the pipeline. Then, the upper nut 32 is spirally moved to press down on the top of the support plate 34, thereby fixing the support plate 34 to the screws 31 between the upper nut 32 and the lower nut 33.

[0027] In summary, as Figure 1-4As shown, this is a device for connecting thermal pipelines. In use, after the ends of two thermal pipelines are welded, the lower connecting semicircular cover 2 can be moved to the bottom of the upper connecting semicircular cover 1, and the ends of the two thermal pipelines are placed inside between the lower connecting semicircular cover 2 and the upper connecting semicircular cover 1. Then, three assembly bolts 6 are screwed into the inside between three lower assembly nuts 7 and upper assembly nuts 8, thereby assembling the lower connecting semicircular cover 2 and the upper connecting semicircular cover 1 together. The lower connecting semicircular cover 2 and the upper connecting semicircular cover 1 are used to limit the connection point of the two thermal pipelines. Then, multiple positioning bolts 5 are screwed and moved so that one end of the multiple positioning bolts 5 abuts against the outer wall of the two thermal pipelines, thereby further limiting the connection between the two pipelines and maintaining the stability between the two pipelines.

[0028] The mounting plate 3 can be fixed in a designated position by using bolts through the mounting port 37. By spirally moving the lower nut 33 below the two screws 31, the support plate 34 can move on the outer wall of the two screws 31 and the two guide rods 36. The support plate 34 can also adjust the position of the upper and lower docking semicircular covers 1 and 2 through the fixing bracket 35, so as to facilitate the adjustment of the position of the upper and lower docking semicircular covers 1 and 2 for supporting and limiting the pipeline. Then, the upper nut 32 is spirally moved to press the upper nut 32 down on the top of the support plate 34, so as to facilitate the fixation of the position of the support plate 34.
