Description

Technical Field

[0001] This utility model belongs to the technical field of support limiting devices, specifically relating to an outdoor heating pipeline support limiting device. Background Technology

[0002] External heating pipelines, as the core infrastructure of urban centralized heating systems, are responsible for transporting high-temperature media ranging from 40-150℃. Their stable operation is directly related to people's livelihood and energy efficiency. Support limiting devices, as key supporting components of the pipeline system, must simultaneously fulfill three major functions: first, to bear the weight of the pipeline, the medium, and the insulation layer and transfer it to the foundation structure; second, to restrain unreasonable displacement of the pipeline caused by temperature differences, preventing joint seal failure; and third, to adapt to the thermal expansion and contraction deformation of the pipeline, preventing stress concentration that could lead to pipeline damage.

[0003] For fixing heating pipes, the current limiting devices mostly adopt the traditional structure of "U-bolt + arc-shaped pressure plate + multiple sets of nuts". During installation, the pipe must first be hoisted to the bracket reference position, and then the pressure plate must be manually adjusted to fit against the outer wall of the pipe. After aligning 3-4 sets of bolt holes one by one, the fasteners are tightened. The installation time of a single bracket often exceeds 15 minutes, which significantly reduces the construction progress. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide an outdoor heating pipe support limiting device. When fixing the pipe, the entire installation and fixing process is highly efficient and labor-saving. It only requires rotating the internal hexagonal connector to release the clamping seat's limitation and rotating it to open. After the pipe is placed in, its own weight pushes the clamping seat back to its original position and fits in place. No manual adjustment is required. Subsequent fixing can also be completed by simply rotating the internal hexagonal connector in the opposite direction. This greatly reduces the use of bolts, nuts, and other fasteners, thereby effectively simplifying the fixing operation of heating pipes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an outdoor heating pipe support limiting device, comprising a base, a support column connected to the top of the base, a U-shaped positioning bracket connected to the top of the support column, transmission chambers on both the left and right sides of the U-shaped positioning bracket, a clamping seat receiving groove extending through the inner and outer sides of the U-shaped positioning bracket, a clamping seat provided on the inner side of the clamping seat receiving groove, a shock-absorbing pad fixedly provided on the arc-shaped clamping surface of the clamping seat, a positioning groove on the outer side of the clamping seat, a bearing seat provided on the inner side of the transmission chamber, and a bearing seat on the inner side of the bearing seat. A second rotating shaft is rotatably mounted, and a first bevel gear is connected to the bottom end of the second rotating shaft. The inner side of the transmission chamber is provided with two sets of sleeves, front and rear. A telescopic positioning rod is slidably mounted on the inner side of the sleeve. A double-acting screw is installed through and rotatably on the side of the two sets of sleeves facing each other. The double-acting screw is threadedly connected to the telescopic positioning rod. A second bevel gear is fixedly sleeved on the outer side of the middle section of the double-acting screw. The second bevel gear meshes with the first bevel gear. An internal hexagonal connector is connected to the top end of the second rotating shaft. An insertion hole is provided on the top of the transmission chamber. The insertion hole is inserted and connected to a locking mechanism.

[0006] The beneficial effects of this utility model are as follows: When fixing pipelines, the entire installation and fixing process of this device is highly efficient and labor-saving. It only requires rotating the internal hexagonal connector to release the limit of the clamping seat and rotating it to open. After the pipeline is placed in, its own weight pushes the clamping seat back to its original position and fits in place. No manual adjustment is required. Subsequent fixing can also be completed by simply rotating the internal hexagonal connector in the opposite direction. This greatly reduces the use of fasteners such as bolts and nuts, thereby effectively simplifying the fixing operation of thermal pipelines. At the same time, this device adopts a double protection of locking mechanism to fix the clamping seat with a telescopic positioning rod and a positioning groove, which locks the transmission mechanism. This double protection prevents loosening from both the mechanical structure and the transmission source, ensuring that the pipeline clamping is stable and reliable. The arc-shaped contact surface of the clamping seat is combined with the flexible buffer of the shock-absorbing pad, which can not only avoid rigid contact damage to the pipeline, but also absorb vibration and adapt to the thermal expansion and contraction characteristics of the pipeline.

[0007] To limit the maximum unfolding angle of the clamping seat:

[0008] As a further improvement to the above technical solution: a lateral limiting frame is provided on the outside of the transmission compartment.

[0009] The beneficial effects of this improvement are: the clamping seat opens by rotating to both sides through the first rotating axis, and the maximum unfolding angle of the clamping seat is limited by the lateral limiting frame.

[0010] As a further improvement to the above technical solution: the clamping seat is provided with a first rotating shaft on both the front and rear sides, and the first rotating shaft is rotatably connected to the groove wall of the clamping seat receiving groove.

[0011] The clamping seat rotates via the first rotating shaft, satisfying the requirements for the clamping seat to rotate, open, and return to its original position.

[0012] As a further improvement to the above technical solution: the surface of the shock-absorbing pad is provided with anti-slip texture.

[0013] The beneficial effect of this improvement is that the anti-slip texture increases the friction between the shock-absorbing pad and the pipe.

[0014] To improve clamping stability:

[0015] As a further improvement to the above technical solution: the locking mechanism includes a horizontal plate, the bottom of which is provided with a hexagonal socket and an insertion tube. The hexagonal socket is inserted into a hexagonal connector, and the insertion tube is inserted into a socket. Screw holes are provided between the bottom of the insertion tube and the top of the horizontal plate, and at the bottom of the socket. The horizontal plate, the insertion tube, and the socket are fixed by hexagonal bolts threaded into the screw holes.

[0016] The beneficial effects of this improvement are as follows: After re-inserting the hexagonal socket and insertion tube at the bottom of the locking mechanism into the internal hexagonal connector and socket respectively, and fixing the locking mechanism with internal hexagonal bolts, the locking mechanism further avoids the possibility of loosening by locking the internal hexagonal connector, thus improving clamping stability.

[0017] To ensure the internal hex connector is completely secured by the hex socket:

[0018] As a further improvement to the above technical solution: the inner hole size of the hexagonal connector matches the outer contour size of the hexagonal socket, and the two fit together without gaps after insertion.

[0019] The beneficial effects of this improvement are: the inner hole size of the internal hexagonal connector matches the outer contour size of the hexagonal socket, and the two fit together without gap after insertion, so that the internal hexagonal connector is completely fixed by the hexagonal socket and will not loosen.

[0020] To maintain stability between the insertion tube and the socket:

[0021] As a further improvement to the above technical solution: the length of the insertion tube is consistent with the depth of the insertion hole, and the outer wall of the insertion tube is in close contact with the inner wall of the insertion hole.

[0022] The beneficial effects of this improvement are: the length of the insertion tube is consistent with the depth of the insertion hole, and the outer wall of the insertion tube is in close contact with the inner wall of the insertion hole, which can maintain the stability between the insertion tube and the insertion hole and prevent shaking.

[0023] In summary, the beneficial effects of this case are as follows:

[0024] 1. When fixing pipelines, this device makes the entire installation and fixing process efficient and labor-saving. It only requires rotating the internal hexagonal connector to release the limit of the clamping seat and rotate it to open. After the pipeline is placed in, its own weight pushes the clamping seat back to its original position and fits. No manual adjustment is required. Subsequent fixing can also be completed by simply rotating the internal hexagonal connector in the opposite direction. This greatly reduces the use of fasteners such as bolts and nuts, thus effectively simplifying the fixing operation of thermal pipelines.

[0025] 2. This device uses a telescopic positioning rod and a positioning groove to lock the clamping seat and lock the transmission mechanism, providing double protection. This eliminates loosening from both the mechanical structure and the transmission source, ensuring that the pipe clamping is stable and reliable.

[0026] 3. The combination of the arc-shaped contact surface of the clamping seat and the flexible buffer of the shock-absorbing pad can not only avoid damage to the pipeline by rigid contact, but also absorb vibration and adapt to the operating characteristics of the pipeline's thermal expansion and contraction.

[0027] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0036] like Figure 1-6 As shown, an outdoor heating pipe support limiting device includes a base 1, a support column 2 connected to the top of the base 1, a U-shaped positioning bracket 3 connected to the top of the support column 2, transmission chambers 4 on both sides of the U-shaped positioning bracket 3, a clamping seat receiving groove extending through the inner and outer sides of the U-shaped positioning bracket 3, a clamping seat 7 on the inner side of the clamping seat receiving groove, a shock-absorbing pad 8 fixedly mounted on the arc-shaped clamping surface of the clamping seat 7, a positioning groove 9 on the outer side of the clamping seat 7, a bearing seat 10 on the inner side of the transmission chamber 4, and a second rotating shaft 11 rotatably mounted on the inner side of the bearing seat 10. The bottom end is connected to a first bevel gear 12. The inner side of the transmission chamber 4 is provided with two sets of sleeves 13, one in front and one behind. A telescopic positioning rod 14 is slidably installed on the inner side of the sleeve 13. Both sets of sleeves 13 are connected to a bidirectional lead screw 15 on the side facing each other and rotate together. The bidirectional lead screw 15 is threadedly connected to the telescopic positioning rod 14. A second bevel gear 16 is fixedly sleeved on the outer side of the middle section of the bidirectional lead screw 15. The second bevel gear 16 meshes with the first bevel gear 12. The top end of the second rotating shaft 11 is connected to an internal hexagonal connector 17. The top of the transmission chamber 4 is provided with an insertion hole 18. The insertion hole 18 is inserted and connected to the locking mechanism 19.

[0037] When fixing pipelines, this device makes the entire installation and fixing process highly efficient and labor-saving. It only requires rotating the internal hexagonal connector 17 to release the limit of the clamping seat 7 and rotate it to open. After the pipeline is placed in, its own weight pushes the clamping seat 7 back to fit. No manual adjustment is required. Subsequent fixing can also be completed by simply rotating the internal hexagonal connector 17 in the opposite direction. This greatly reduces the use of fasteners such as bolts and nuts, thus effectively simplifying the fixing operation of thermal pipelines. At the same time, this device adopts the double protection of the telescopic positioning rod 14 and the positioning groove 9 to fix the clamping seat 7 and the locking mechanism 19 to lock the transmission mechanism. It prevents loosening from both the mechanical structure and the transmission source, ensuring that the pipeline is clamped firmly and reliably. The arc-shaped contact surface of the clamping seat 7 is combined with the flexible buffer of the shock-absorbing pad 8, which can not only avoid rigid contact damage to the pipeline, but also absorb vibration and adapt to the thermal expansion and contraction characteristics of the pipeline.

[0038] The transmission compartment 4 is provided with a lateral limiting frame 5 on its outer side.

[0039] The clamping seat 7 is opened by rotating to both sides via the first rotating shaft 6, and the maximum unfolding angle of the clamping seat 7 is limited by the lateral limiting frame 5.

[0040] The clamping seat 7 is provided with a first rotating shaft 6 on both the front and rear sides, and the first rotating shaft 6 is rotatably connected to the groove wall of the clamping seat receiving groove.

[0041] The clamping seat 7 rotates via the first rotating shaft 6, satisfying the requirements for the clamping seat to rotate, open, and reset.

[0042] The surface of the shock-absorbing pad 8 is provided with anti-slip texture.

[0043] The anti-slip texture is used to increase the friction between the shock-absorbing pad 8 and the pipe.

[0044] The locking mechanism 19 includes a horizontal plate 20. The bottom of the horizontal plate 20 is provided with a hexagonal socket 21 and an insertion tube 22. The hexagonal socket 21 is inserted and connected to an internal hexagonal connector 17. The insertion tube 22 is inserted and connected to a socket 18. The bottom of the insertion tube 22 and the top of the horizontal plate 20, as well as the bottom of the socket 18, are provided with screw holes. The horizontal plate 20, the insertion tube 22, and the socket 18 are fixed by internal hexagonal bolts 23 threadedly connected to the screw holes.

[0045] After re-inserting the hexagonal socket 21 and insertion tube 22 at the bottom of the locking mechanism 19 into the internal hexagonal connector 17 and the socket 18 respectively, and fixing the locking mechanism 19 with the internal hexagonal bolt 23, the locking mechanism 19 is further prevented from loosening by locking the internal hexagonal connector 17 through the locking mechanism 19, thus improving the clamping stability.

[0046] The inner hole size of the hexagonal connector 17 matches the outer contour size of the hexagonal socket 21, and the two fit together without gaps after insertion.

[0047] The inner diameter of the hexagonal connector 17 matches the outer diameter of the hexagonal socket 21, and the two fit together without gap after insertion, so that the hexagonal connector 17 is completely fixed by the hexagonal socket 21 and will not loosen.

[0048] The length of the insertion tube 22 is the same as the depth of the insertion hole 18, and the outer side wall of the insertion tube 22 is in close contact with the inner side wall of the insertion hole 18.

[0049] The length of the insertion tube 22 is consistent with the depth of the socket 18, and the outer wall of the insertion tube 22 is in close contact with the inner wall of the socket 18, which can maintain the stability between the insertion tube 22 and the socket 18 and prevent shaking.

[0050] The working principle and usage process of this utility model are as follows: When using this device, the base 1 is fixed to the ground with bolts, and then the pipe can be installed. When installing the pipe, first use a hex wrench to unscrew the internal hex bolt 23 and remove the locking mechanism 19. Then use a hex wrench to rotate the internal hex connector 17. The internal hex connector 17 drives the second rotating shaft 11 and the first bevel gear 12 to rotate. The transmission between the first bevel gear 12 and the second bevel gear 16 drives the bidirectional lead screw 15 to rotate. Thus, the helical transmission between the bidirectional lead screw 15 and the telescopic positioning rod 14 drives the two telescopic positioning rods 14 located in the same transmission chamber 4 to move closer to each other, so that the telescopic positioning rods 14 disengage. The clamping seat 7 is positioned between the positioning groove 9 and the positioning bracket 9. At this time, the clamping seat 7 can be rotated to both sides via the first rotating shaft 6 to open. The maximum unfolding angle of the clamping seat 7 is limited by the lateral limiting bracket 5, which facilitates the subsequent installation of the pipe. The pipe is placed inside the U-shaped positioning bracket 3 from above. When the pipe descends between the clamping seats 7 on the left and right sides, as the pipe descends, it contacts the junction of the bottom of the arc-shaped clamping surface and the flat surface of the clamping seat 7, pushing the clamping seat 7 to rotate and reset via the first rotating shaft 6, so that the clamping seat 7 clamps the pipe from both sides, and the shock-absorbing pad 8 provides a shock-absorbing effect. Then, the internal hexagonal connector 17 is rotated in the opposite direction to drive the telescopic positioning rod 14 to extend out of the pipe sleeve 13 again. The device inserts the device into the positioning groove 9 to limit the clamping seat 7, preventing it from rotating outward under external force, thus firmly clamping the pipe. Then, the hexagonal socket 21 and insertion tube 22 at the bottom of the locking mechanism 19 are reinserted into the internal hexagonal connector 17 and insertion hole 18, respectively, and the locking mechanism 19 is secured with internal hexagonal bolts 23. The locking mechanism 19 further prevents loosening of the internal hexagonal connector 17, improving clamping stability. In summary, this device makes the entire pipe installation and fixing process efficient and labor-saving. It only requires rotating the internal hexagonal connector 17 to release the clamping seat 7 and open it up. After the pipe is placed, its own weight pushes the clamping seat 7 back to its original position and fit, eliminating the need for manual adjustment. Subsequent fixing only requires rotating the internal hexagonal connector 17 in the reverse direction, significantly reducing the use of bolts, nuts, and other fasteners, thus effectively simplifying the fixing operation of the thermal pipeline. At the same time, this device uses the telescopic positioning rod 14 and the positioning groove 9 to fix the clamping seat 7, and the locking mechanism 19 to lock the transmission mechanism, providing double protection. This eliminates loosening from both the mechanical structure and the transmission source, ensuring that the pipe clamping is stable and reliable. The arc-shaped contact surface of the clamping seat 7 combined with the flexible buffer of the shock-absorbing pad 8 can not only avoid rigid contact damage to the pipe, but also absorb vibration and adapt to the thermal expansion and contraction characteristics of the pipe.
