Description

Technical Field

[0001] This utility model specifically relates to a displacement embedded part for heat pipe welding, belonging to the field of heating network construction. Background Technology

[0002] Central heating generates heat at a centralized heating station and then distributes it to various buildings through a heating pipe network. During construction, this network is typically laid directly underground. Before laying the horizontally buried pipes, trenches need to be excavated, with fine sand laid at the bottom. The heat pipes are then placed in the trenches and connected and secured. Adjacent heat pipes are usually connected by welding. However, due to the large size and weight of the heat pipes, welding is difficult due to specifications and weight limitations, making rotation and movement challenging. Given the fixed horizontal position of the heat pipes, the only option is to continue digging downwards at the connection point. Because the location of the heat pipes is low-lying, workers must stand inside the pit to weld the lower connection point. This process has the following drawbacks:

[0003] 1. Lack of standardized deep excavation procedures: During construction, an additional pit-digging process was added. The location and size of the deep excavation were not standardized. As a result, it was difficult to predict and control the impact of the secondary deep excavation on the original location of the heat pipe and its subsequent use.

[0004] 2. High difficulty in welding operation: Because the heat pipe is fixed in a horizontal position, the welding position is low and hidden, and there is a lack of favorable welding angle. When workers carry out welding operations in the pit, they are often limited by space conditions and can only operate upwards. The welding construction position is greatly restricted, which significantly increases the difficulty of welding operations.

[0005] 3. Difficulty in standardizing subsequent maintenance operations: If a malfunction occurs after the heat pipe is put into use, a trench needs to be dug for inspection and repair. However, the inability to rotate the heat pipe during maintenance increases the difficulty of subsequent inspection and repair work. Utility Model Content

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention, through the coordinated operation of a support frame, bearing assembly, clamping component, and drive assembly, enables the heat pipe to rotate freely within a trench. The rotation angle and position can be adjusted as needed, ensuring that the heat pipe is positioned at a favorable circumferential angle for welding or other construction processes. When welding heat pipe joints, the pre-embedded displacement component allows the heat pipe to rotate during the welding process, facilitating welding and effectively solving the inconvenience of traditional methods that require digging a pit below the joint and workers entering the pit for welding. This reduces the difficulty of heat pipe processing and establishes a standardized and uniform processing procedure for heat pipes located underground. This invention is applicable to heat pipe applications before they are secured. Attached Figure Description

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0028] Specific implementation method one: Combining Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10This embodiment describes a heat pipe welding indexing embedded part, which includes a support frame 10, a bearing assembly 8, a clamping member 9, and a drive assembly 4. The support frame 10 is formed by two half-frames 1 enclosing each other, and the two half-frames 1 are detachably connected. The bearing assembly 8 is provided inside the support frame 10, and the clamping member 9 is coaxially provided on the bearing assembly 8. The drive assembly 4 is provided on the bearing assembly 8, and the drive assembly 4 meshes with the clamping member 9. The bearing assembly 8 includes two half-bearings 2, which are semi-circular arc structures and are detachably connected. Each half-bearing 2 includes an inner half-ring 2-1, an outer half-ring 2-2, an inner half-ring 2-6, four first side ears 2-3, two T-shaped slides 2-5, and multiple balls 2-4. The inner wall of the outer half-ring 2-2 is provided with an inner half-ring 2-6, and the inner wall of the inner half-ring 2-6 extends along its length. Multiple spherical grooves 2-2-2 are provided in the angular direction, and a ball 2-4 is provided in each spherical groove 2-2-2. A T-shaped groove 2-2-1 is machined on each side edge of the inner wall of the outer half-circle 2-2.

A groove 2-1-1 is machined on the outer wall of the inner half-circle 2-1 along its length direction. A T-shaped slider 2-5 is provided on each side edge of the outer wall of the inner half-circle 2-1. The length direction of each T-shaped slider 2-5 is in the same direction as the circumference of the inner half-circle 2-1. The T-shaped slider 2-5 and the T-shaped groove 2-2-1 are slidably engaged in a one-to-one correspondence. The inner half-ring 2-6 is slidably disposed in the groove 2-1-1. Multiple balls 2-4 are in contact with the inner wall of the groove 2-1-1 respectively. A first side ear 2-3 is provided on each side outer wall of the outer half-circle 2-2.

[0029] Place one end of the heat pipe 5 on the inner wall of the inner half ring 2-1, and then form a bearing assembly 8 by assembling the two half bearings 2. With the assistance of multiple balls 2-4, the two inner half rings 2-1 can rotate smoothly along the circumference of the two outer half rings 2-2, thereby driving the heat pipe 5 on it to rotate. The heat pipe 5 rotates with the welding process, so that the worker can complete the welding work of the two heat pipes 5 in the trench without having to dig an additional tunnel below the heat pipe 5 for welding work below the heat pipe 5.

[0030] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One, and also includes a plurality of first bolts 7. Each first bolt 7 is inserted between two opposite first side ears 2-3 of the two half bearings 2. When the two half bearings 2 are in an enclosed connection state, one end of each first bolt 7 is connected to one of the first side ears 2-3 of one half bearing 2, and the other end of each first bolt 7 is connected to one of the first side ears 2-3 of the other half bearing 2.

[0032] The U-shaped bracket 1-1 serves to stably support the heat pipe 5.

[0033] Specific implementation method four: This implementation method is a further limitation of specific implementation methods one, two or three, and also includes a plurality of second bolts 11. Each second bolt 11 is inserted between two opposite second side ears 1-3 of the two half-frames 1. When the two half-frames 1 are in an enclosed connection state, one end of each second bolt 11 is connected to one of the second side ears 1-3 of one half-frame 1, and the other end of each second bolt 11 is connected to one of the second side ears 1-3 of the other half-frame 1.

[0034] Specific Implementation Method 5: This implementation method is a further limitation of Specific Implementation Methods 1, 2, 3 or 4. The clamping component 9 includes two semi-circular clamping pieces 3, which are detachably connected. Each inner half-circle 2-1 is provided with a corresponding semi-circular clamping piece 3. Each semi-circular clamping piece 3 includes a semi-circular plate 3-1, multiple screws 3-2 and multiple teeth 3-3. The semi-circular plate 3-1 is provided on the side wall of an inner half-circle 2-1. Multiple teeth 3-3 are provided on one side of the outer wall of the semi-circular plate 3-1. Multiple screw holes 3-1-1 are machined on the other side of the outer wall of the semi-circular plate 3-1. Each screw hole 3-1-1 is internally threaded with a screw 3-2.

[0035] When the end of the heat pipe 5 is placed inside the inner half-circle 2-1, rotate the screw 3-2 so that the end of the screw 3-2 is against the outer wall of the heat pipe 5, thereby clamping the heat pipe 5 and making it easier for the semi-circular clamping plate 3 to drive the heat pipe 5 to rotate.

[0036] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, or Five. A driving assembly 4 is provided on one of the two outer semicircles 2-2. The driving assembly 4 includes a push rod 4-1, a connector 4-2, a slide 4-3, a pawl 4-4, a spring-loaded washer 4-5, and a connecting plate 4-6. The connecting plate 4-6 is disposed on the outer side wall of the outer semicircle 2-2. An arc-shaped groove 4-6-1 is machined on the connecting plate 4-6 along its length direction. The arc-shaped groove 4-6-1 has a sliding groove inside. A sliding member 4-3 is provided, and a connecting member 4-2 is provided on the sliding member 4-3. A push rod 4-1 is provided at the upper end of the connecting member 4-2, and a cavity 4-2-1 is machined at the lower end of the connecting member 4-2. A spring-shaped washer 4-5 is provided inside the cavity 4-2-1. One end of the spring-shaped washer 4-5 is in contact with the inner wall of the cavity 4-2-1. A pawl 4-4 is slidably provided inside the cavity 4-2-1. The other end of the spring-shaped washer 4-5 is in contact with one end of the pawl 4-4, and the other end of the pawl 4-4 is engaged with the tooth 3-3.

[0037] Pushing the push rod 4-1 to the left along the length of the arc groove 4-6-1 causes the connector 4-2 to move the pawl 4-4 to the left. At this time, the pawl 4-4 is squeezed by the teeth 3-3 and moves into the cavity 4-2-1. When it is necessary to rotate the heat pipe 5, push the push rod 4-1 to the right along the length of the arc groove 4-6-1. At this time, the pawl 4-4 is stuck at the teeth 3-3. By pushing the teeth 3-3, the semi-circular clamping plate 3 drives the corresponding inner half circle 2-1 to rotate, thereby driving the heat pipe 5 to rotate.

[0038] Specific implementation method seven: This implementation method is a further limitation of specific implementation methods one, two, three, four, five or six. A foot 6 is provided on each of the two outer walls of the U-shaped frame 1-1. The foot 6 can stably place the pre-embedded part for welding the heat pipe in the groove.

[0039] Specific implementation method eight is a further limitation of specific implementation methods one, two, three, four, five, six or seven. In this implementation method, a method of using a heat pipe welding embedded part is specifically implemented by using a heat pipe welding embedded part. Specifically, a heat pipe welding embedded part is set at both ends of each heat pipe 5. The support frame 10 and the bearing assembly 8 are split into two halves. The end of the heat pipe 5 is placed in one half of the bearing assembly 8. Then, the other half of the support frame 10 and the bearing assembly 8 are installed and connected in a detachable manner so that the support frame 10 and the bearing assembly 8 form a whole. When welding the connection between the two heat pipes 5, the welding position can be changed by rotating the heat pipe 5.

[0040] This utility model is used in conjunction with the initial laying of heat pipe 5, and can also be used in conjunction with maintenance after heat pipe 5 has been put into use.

[0041] This utility model is applicable to use before the heat pipe 5 is positioned and fixed, that is, it is applicable to use when the overall structure of the heat pipe 5 is mostly exposed or the overall structure is not buried. This utility model is only applicable to use when the heat pipe 5 is not buried.

[0042] Working principle:

[0043] Multiple heat pipes 5 are laid sequentially in the excavated trench. A pre-embedded part is installed at both ends of each heat pipe 5. After the support frame 10 and bearing assembly 8 are separated into upper and lower half-frames 1 and half-bearings 2, one end of the heat pipe 5 is placed on the inner wall of the lower inner half-circle 2-1. Then, the upper half-frame 1 and half-bearings 2 are connected by bolts 7 to form the support frame 10 and bearing assembly 8. When welding the two heat pipes 5, after the upper half of the two heat pipes 5 is welded, the heat pipes 5 can be rotated to move the two heat pipes 5 from the bottom position to the top, so that the workers can form a standard welding angle and continue the welding operation.
