Description

Technical Field

[0001] This application relates to the technical field of construction, and particularly to a telescopic cooling water pipe docking device. Background Art

[0002] In the modern industrial field, the cooling system plays a crucial role, which is directly related to the heat dissipation effect and stable operation of equipment.

[0003] The telescopic cooling water pipe is an important component in the cooling system. The telescopic cooling water pipe is used to transport coolant (water, oil or other liquid media). The telescopic cooling water pipe is commonly used in construction projects to connect equipment such as cooling towers, air conditioning systems, and boilers. The telescopic cooling water pipe is a water pipe that can automatically expand and contract according to temperature changes or other factors. This design helps to compensate for the length changes of the pipeline caused by thermal expansion and contraction, ensuring the normal operation of the pipeline system and reducing damage caused by excessive stretching or compression.

[0004] In the prior art, pipeline expansion joints, compensators and other pipeline expansion components can be installed in the straight section of the cooling water pipe to achieve the purpose that the cooling water pipe can expand and contract according to temperature changes. The expansion joint usually consists of a sleeve, a housing and a sealing material, and can absorb the thermal expansion or contraction of the pipeline; the compensator is a device specially designed to compensate for the thermal expansion of the pipeline, and they can be in the form of bellows, casing type or spherical, etc. The compensator absorbs the length change of the pipeline through its flexible structure and reduces the thermal stress.

[0005] When the staff constructs the cooling water pipe, it is necessary to align two straight pipe sections, and then use components such as expansion joints or compensators to connect the two straight pipe sections. Therefore, when the staff installs the expansion joint or compensator, there are relatively high requirements for the docking accuracy of the two straight pipe sections, resulting in low efficiency when the staff docks the straight pipe sections.

Detailed Description of the Embodiments

[0037] The following further elaborates on this application in conjunction with the attached Figures 1 - 6 drawings.

[0038] Embodiment 1

[0039] This application embodiment discloses a telescopic cooling water pipe butt-joint device. Refer to Figure 1, the cooling water pipe is spliced by a plurality of straight pipe segments 1 and pipe expansion joints 2, and the pipe expansion joint 2 is fixedly arranged between two straight pipe segments 1. The cooling water pipe includes the direct alignment connection of two straight pipe segments 1 and the alignment connection of two straight pipe segments 1 and the pipe expansion joint 2. In this embodiment, the alignment connection of two straight pipe segments 1 and the pipe expansion joint 2 is taken as an example to explain the working principle of the telescopic cooling water docking device. The pipe expansion joint 2 can be an expansion joint, a compensator and other expansion devices; in this embodiment, the pipe expansion joint 2 is a corrugated compensator. At the same time, a first flange 11 is provided at the end of the straight pipe segment 1, and second flanges 21 are provided at both ends of the pipe expansion joint 2, and the first flange 11 and the second flange 21 are fixedly connected by bolts.

[0040] Refer to Figure 2 , the telescopic cooling water pipe docking device includes a hoop 3, a cushion block 4 and a traction assembly 5.

[0041] Two hoops 3 are arranged coaxially opposite to each other. The hoop 3 is used to fix the straight pipe segment 1 so that the central axes of the two straight pipe segments 1 are on the same straight line. The hoop 3 includes two relatively arranged hoop plates 31, connecting bolts 32 and connecting nuts 33. The two hoop plates 31 enclose an installation space for accommodating the straight pipe segment 1. Installation holes for the transmission of connecting screws are provided on both sides of the hoop plate 31. Through the cooperation of the connecting bolts 32 and the connecting nuts 33, the two relatively arranged hoop plates 31 are used to tightly hoop the straight pipe segment 1.

[0042] There are two cushion blocks 4. The two cushion blocks 4 are arranged relatively, and the two cushion blocks 4 correspond to the two hoop plates 31 respectively. The cushion block 4 is semi-circular, and the cushion block 4 is detachably connected to the hoop plate 31. Thus, by replacing the cushion blocks 4 with different thicknesses, the size of the accommodation space of the hoop 3 for accommodating the straight pipe segment 1 can be changed, so that the docking device is applicable to straight pipe segments 1 with different diameters, and the use range of the docking device is improved.

[0043] In this embodiment, a limiting rib 41 is provided on the outer periphery of the cushion block 4, and a limiting groove 34 for inserting the limiting rib 41 is provided on the hoop plate 31. That is, the cushion block 4 is inserted and fixed to the hoop plate 31, which is convenient for the staff to install the docking device. In other embodiments, the cushion block 4 and the hoop plate 31 can also be connected by fastening bolts.

[0044] The traction assembly 5 is fixedly connected to the two hoops 3, and the traction assembly 5 is used to drive the two hoops 3 to approach each other. The traction assembly 5 includes a first fixing block 51, a second fixing block 52, a traction rod 53 and a rotating rod 54. The first fixing block 51 and the second fixing block 52 are respectively fixedly connected to the two hoops 3. The fixing methods of the first fixing block 51, the second fixing block 52 and the hoop 3 are the same. In this embodiment, the first fixing block 51 is taken as an example to explain. The first fixing block 51 is provided with an accommodation groove 511 for accommodating the hoop 3, and the first fixing block 51 and the hoop 3 are fixedly connected by bolts.

[0045] The first fixing block 51 is fixedly connected to the towing rod 53. The second fixing block 52 is provided with a first mounting hole 521 for the towing rod 53 to pass through. The towing rod 53 is slidably connected to the second fixing block 52. The length direction of the towing rod 53 is parallel to the virtual connection line of the two hoop clamps 3. A rack 531 is provided on the side of the towing rod 53 away from the hoop clamp 3. The second fixing block 52 is further provided with a second mounting hole 522 for the rotating rod 54 to pass through, and the first mounting hole 521 is communicated with the second mounting hole 522. An external gear ring 541 meshing with the rack 531 is provided on the outer periphery of the rotating rod 54.

[0046] The implementation principle of a telescopic cooling water pipe docking device according to an embodiment of the present application is as follows:

[0047] The staff first fixedly connect the two hoop clamps 3 to the ends of the two straight pipe sections 1. Subsequently, the towing rod 53 is passed through the first mounting hole 521 of the second fixing block 52, and the rotating rod 54 is passed through the second mounting hole 522 of the second fixing block 52, and the external gear ring 541 on the rotating rod 54 is meshed with the rack 531. Thus, when the staff rotates the rotating rod 54, through the coordinated cooperation of the external gear and the rack 531, the second fixing block 52 will carry the straight pipe section 1 and move towards the first fixing block 51 to reduce the distance between the two straight pipe sections 1; at the same time, it is also ensured that during the movement of the two straight pipe sections 1, the central axes of the two straight pipe sections 1 are located on the same straight line segment.

[0048] When the ends of the two straight pipe sections 1 move to the designed distance, the staff can arrange the pipe expansion joint 2 between the two straight pipe sections 1 and make the through holes of the first flange 11 and the second flange 21 face each other. The staff continues to rotate the rotating rod 54, so that the two straight pipe sections 1 clamp the pipe expansion joint 2 under the action of the traction assembly 5. The staff then uses bolts to connect the first flange 11 and the second flange 21, thereby realizing the docking installation of the straight pipe section 1 and the pipe expansion joint 2 and improving the docking installation efficiency of the cooling water pipe.

[0049] Embodiment 2

[0050] The difference between this Embodiment 2 and Embodiment 1 is that:

[0051] The spacer block 4 is provided with a stepped hole 42 for the bolt to pass through, and the hoop plate 31 is provided with a threaded groove 35 for the bolt to be inserted. The spacer block 4 and the hoop plate 31 are fixedly connected by bolts; that is, the spacer block 4 and the hoop plate 31 are fixedly connected by fastening bolts, thereby improving the connection stability between the spacer block 4 and the hoop plate 31 and facilitating the staff to carry the docking device to multiple pipe docking points.

[0052] Embodiment 3

[0053] The difference between this Embodiment 3 and Embodiment 1 is that:

[0054] The docking device further includes a fixing rod 6 which sequentially passes through the through holes of the first flange 11, the second flange 21, and the second flange 21 and the first flange 11. The fixing rod 6 is used to dispose the pipeline expansion joint 2 between two straight pipe segments 1. In this embodiment, there are two fixing rods 6; when through holes are provided at the highest points of the first flange 11 and the second flange 21, one fixing rod 6 can also be provided. In this embodiment, two fixing rods 6 are provided to reduce the rotation of the pipeline expansion joint 2, so that the through holes of the first flange 11 and the second flange 21 are arranged opposite to each other, facilitating the staff to connect the first flange 11 and the second flange 21 with bolts and nuts.

[0055] In this embodiment, the fixing rod 6 includes an abutting rod section 61 and a guiding rod section 62. The guiding rod section 62 is disposed on both sides of the abutting rod section 61, and the abutting rod section 61 and the guiding rod section 62 are integrally formed; along the direction away from the abutting rod section 61, the outer diameter of the guiding rod section 62 decreases.

[0056] The implementation principle of a telescopic cooling water pipe docking device according to an embodiment of the present application is as follows:

[0057] After the staff passes the fixing rod 6 through the through holes of the second flanges 21 at both ends of the pipeline expansion joint 2, then the pipeline expansion joint 2 is disposed between two straight pipe segments 1. When the two straight pipe segments 1 approach each other under the action of the traction assembly 5, the guiding rod sections 62 at both ends of the fixing rod 6 pass through the through holes of the first flange 11; thereby, the pipeline expansion joint 2 is relatively fixed between the two straight pipe segments 1 through the fixing rod 6. When the first flange 11 abuts against the second flange 21, the through holes of the first flange 11 and the second flange 21 are arranged opposite to each other, facilitating the staff to fix the straight pipe segment 1 and the pipeline expansion joint 2 with bolts and nuts.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
