Description

Technical Field

[0001] This invention relates to the field of fixed installation technology for suspended pipes, and in particular to a fixed device for suspended pipes. Background Technology

[0002] Currently, when installing pipelines, in order to optimize the spatial layout and minimize the impact on the installed pipelines and pipeline transportation, clamps are usually used to fix the pipelines to the ceiling.

[0003] The clamp consists of a first half-ring, a second half-ring, and two bolts. Half-ring one is positioned above and directly opposite half-ring two. Both half-rings are recessed inwards towards each other. The two bolts are located on opposite sides of half-rings one and two along their length, and are threaded through half-rings one and two to connect to nuts. During pipe installation, half-rings one and two are typically fitted over the outside of the pipe. Together with the pipe, half-rings one and two are used to lift the pipe to a certain height using temporary support equipment. The operator then connects and secures the half-rings to the ceiling, thereby suspending and supporting the pipe using half-rings one and two, thus completing the stable installation of the pipe.

[0004] Regarding the aforementioned technologies, the pipeline is already relatively fixed before installation, along with half-ring one and half-ring two. At this point, the pipeline is restricted. If the position of the pipeline needs to be adjusted, the installation position of the clamps needs to be readjusted, making the installation process inconvenient. Therefore, there is an urgent need for a pipeline fixing device that can adjust the position of the pipeline after installation. Summary of the Invention

[0005] To improve the convenience of pipe adjustment, this application provides a suspended pipe fixing device.

[0006] Firstly, this application provides a suspended pipe fixing device, which adopts the following technical solution: A suspended pipe fixing device includes a clamp, a horizontal plate, and a C-shaped steel. The horizontal plate is slidably connected to the C-shaped steel along its length. Screws are provided at both ends of the horizontal plate along its length. The screws are vertically positioned and pass through the horizontal plate, rotating with it. A fixing block is coaxially provided at one end of each screw along its length. The fixing block has inclined surfaces on both sides along its transverse direction and is located inside the C-shaped steel. When the screw is rotated, the inclined surfaces of the fixing block approach or move away from the inner wall of the open opening of the C-shaped steel. A nut is threaded onto the screw and is located on the side of the horizontal plate away from the fixing block. The clamp has a threaded post, and an installation tube adapted to the threaded post is provided on the side of the horizontal plate away from the C-shaped steel. The threaded post is inserted into the installation tube and threadedly connected to it.

[0007] By adopting the above technical solution, the fixing block 1 abuts against the inner wall of the C-shaped steel through the inclined surface, limiting its own rotation along the axis, and thus limiting the rotation of the bolt. The horizontal plate supports and fixes the installation pipe, the installation pipe supports the threaded column, and the threaded column supports the clamp. When the horizontal plate moves along the length of the C-shaped steel, it drives the clamp to move along the length of the C-shaped steel. By tightening the nut, the screw drives the fixing block 1 to approach the horizontal plate, so that the fixing block 1 and the horizontal plate cooperate to clamp the C-shaped steel, thereby fixing the horizontal plate. This allows the pipe to still be adjusted in position after being fixed by the clamp, which is beneficial to improving the convenience of operators in installing and adjusting the pipe.

[0008] Optionally, a second fixing block is coaxially fixed above the first fixing block. When the inclined surface contacts the inner wall of the C-shaped steel, the second fixing block abuts against the open side of the C-shaped steel on both sides along the length of the first fixing block.

[0009] By adopting the above technical solution, the inner wall of the open side of the C-shaped steel limits the displacement of the second fixing block along its own circumference, thereby limiting the rotation of the bolt along its own axis and further improving the installation stability of the bolt.

[0010] Optionally, the clamp includes a first half-ring and a second half-ring arranged opposite each other. The first half-ring and the second half-ring are connected by bolts. A threaded post is fixed to the side of the first half-ring away from the center. Rubber pads are provided on the inner sides of both the first half-ring and the second half-ring, and the rubber pads are arranged along the inner wall of the clamp.

[0011] By adopting the above technical solution, semi-ring one and semi-ring two contact the pipeline through rubber pads. The rubber pads protect the pipeline, reducing the probability of semi-ring one and semi-ring two causing friction damage to the pipeline during installation, which helps to improve the service life of the pipeline.

[0012] Optionally, the screw has a transverse groove at the end away from the C-shaped steel. The transverse groove is perpendicular to the length direction of the fixing block. In the installed state, the axis of the transverse groove is parallel to the length direction of the C-shaped steel.

[0013] By adopting the above technical solution, the operator can judge the contact between the first and second fixing blocks and the inner wall of the C-shaped steel by the angle of the horizontal groove. If the horizontal groove is parallel to the C-shaped steel, the first fixing block will abut against the inner wall of the C-shaped steel; otherwise, there will be no abutment, thereby improving the installation convenience for the operator.

[0014] Optionally, two arc-shaped plates are slidably connected to the inner side of the semi-ring one along the circumferential direction. A swing arm is hinged to the side of the two arc-shaped plates one that is close to each other. The two sets of swing arms are hinged to the same arc-shaped plate two. The hinge axes of the swing arms and the arc-shaped plates two are parallel to the axis of the semi-ring one. The arc-shaped plates two and the arc-shaped plates one are provided with the same cable tie. The cable tie passes through the two sets of swing arms in sequence. Both ends of the semi-ring one along the length direction have radial through holes. The two ends of the cable tie along the length direction are arranged crosswise and pass out through the adjacent through holes respectively. The semi-ring one is provided with a tensioning device for tightening the cable tie. The bolt on the clamp is rotatably connected to the semi-ring one, and the bolt is locked along the axial direction relative to the displacement of the semi-ring one. The bolt passes through the semi-ring one and is threadedly connected to the semi-ring two.

[0015] By adopting the above technical solution, the two arc-shaped plates support and limit the semi-ring one, the two arc-shaped plates support the two swing arms, and the two swing walls cooperate to support the arc-shaped plate two, so that the swing walls support the cable tie. The cable tie passes through the perforation of the semi-ring one and the semi-ring two. The perforation limits and guides the cable tie. The cable tie is fixed by the tensioning device. The bolt supports the semi-ring one, so that the semi-ring one and the semi-ring two have a gap in the initial state. At the same time, the cable tie pulls the arc-shaped plate two downward under the action of its own weight and the weight of the pipeline, so that there is a gap between the cable tie and the semi-ring one and the semi-ring two, which makes it easier for the operator to adjust the pipeline and improves the convenience of the operator in adjusting the pipeline.

[0016] Optionally, the upper end of the semi-ring is provided with an arc groove to accommodate the arc plate. When the arc plate and the arc plate are located in the arc groove, the arc plate and the swing arm are inside the semi-ring, and the outer edge of the pipe is close to the semi-ring.

[0017] By adopting the above technical solution, the arc groove supports and limits the arc plate one. When the cable tie is in contact with the semi-ring one, the arc groove accommodates the arc plate two and the arc plate one, reducing the probability of the arc plate one and the arc plate two contacting the pipeline and interfering with the pipeline installation.

[0018] Optionally, the tensioning device includes a fixed plate, a sliding plate, and a threaded rod. The fixed plate is fixed to the side of the semi-ring away from its own axis. The sliding plate is slidably connected to the semi-ring along its radial direction, and the sliding plate and the fixed plate are located in the same straight line. The threaded rod passes through the fixed plate and is threadedly connected to the fixed plate. The threaded rod is rotatably connected to the sliding plate. The sliding plate is provided with a one-way buckle adapted to the cable tie. When the cable tie passes through the one-way buckle, it only moves in the tightening direction.

[0019] By adopting the above technical solution, the semi-ring is fixed to a pair of fixed plates and supports the sliding plate. The fixed plate supports the threaded rod. When the cable tie slides, the round rod rolls. When the cable tie moves backward, the round rod presses the cable tie tightly under the action of friction, thereby reducing the probability of the cable tie coming off the one-way buckle and allowing the cable tie to support the pipeline. The operator rotates the threaded rod to make the sliding plate approach the fixed plate. The sliding plate drives the two ends of the cable tie along the length direction to move in opposite directions, thereby tightening the cable tie a second time, so that the cable tie fits against the pipeline and clamps and fixes the pipeline.

[0020] Optionally, a rotating ring is rotatably connected to the mounting tube. A telescopic rod is fixedly provided on the side of the rotating ring facing the second half-ring. The end of the telescopic rod away from the rotating ring is connected to the lower end of the second half-ring. A fixing rod is provided on the rotating ring. The fixing rod passes through the rotating ring radially and is threadedly connected to the rotating ring. The fixing rod passes through the rotating ring and abuts against the mounting tube.

[0021] By adopting the above technical solution, the mounting pipe supports and limits the rotation of the rotating ring, and the rotating ring supports and fixes the telescopic rod. When half-ring one and half-ring two rotate, the length of the telescopic rod along the vertical direction changes, which drives the rotating ring to rotate. When half-ring one and half-ring two rotate to the preset position, the operator rotates the fixing rod to fix the rotation angle of the rotating ring. In turn, the telescopic rod fixes the rotation angle of half-ring one and half-ring two, which helps to improve the stability of half-ring one and half-ring two after rotation.

[0022] In summary, this application includes at least one of the following beneficial technical effects: The first fixing block abuts against the inner wall of the C-shaped steel through the inclined surface, limiting its own rotation along the axis, and thus limiting the rotation of the bolt. The horizontal plate supports and fixes the installation pipe, the installation pipe supports the threaded column, and the threaded column supports the clamp. When the horizontal plate moves along the length of the C-shaped steel, it drives the clamp to move along the length of the C-shaped steel. By tightening the nut, the screw drives the first fixing block to approach the horizontal plate, so that the first fixing block and the horizontal plate cooperate to clamp the C-shaped steel, thereby fixing the horizontal plate. This allows the pipe to still be adjusted in position after being fixed by the clamp, which helps to improve the convenience of pipe installation and adjustment for operators. The inner wall of the open side of the C-shaped steel limits the displacement of the second fixing block along its own circumference, thereby limiting the rotation of the bolt along its own axis and further improving the installation stability of the bolt. Semi-ring one and semi-ring two contact the pipeline through rubber pads. The rubber pads protect the pipeline and reduce the probability of friction damage to the pipeline during installation, which helps to improve the service life of the pipeline.

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] This application discloses a suspension pipe fixing device. Example 1

[0031] Reference Figure 1 and Figure 2 A suspended pipe fixing device includes a horizontal plate 2 and a C-shaped steel 3. The horizontal plate 2 is located on one side of the open end of the C-shaped steel 3. Screws 21 are installed at both ends of the horizontal plate 2 along its length. The screws 21 are perpendicularly connected to the horizontal plate 2 and are inserted into the C-shaped steel 3 and slidably connected to the inner wall of the open end of the C-shaped steel 3. The screws 21 are driven to slide along the length of the C-shaped steel 3. A fixing block 22 is coaxially fixed at one end of the screw 21 near the C-shaped steel 3. The fixing block 22 is located inside the C-shaped steel 3. Both sides of the fixing block 22 are set as inclined surfaces. When the screws 21 are rotated until the fixing block 22 is perpendicular to the C-shaped steel 3, the inclined surfaces abut against the inner wall of the C-shaped steel 3, thereby fixing the displacement of the fixing block 22 along its own circumference, and thus fixing the displacement of the screws 21 along its own circumference.

[0032] Reference Figure 1 and Figure 2 Screw 21 passes through the horizontal plate 2 from bottom to top and is threaded onto nut 23. A washer 26 is installed between screw 21 and nut 23. The operator rotates nut 23, causing nut 23 to push washer 26 closer to horizontal plate 2. The operator tightens nut 23, causing fixing block 22 to move upward, so that fixing block 22 and nut 23 cooperate to press C-shaped steel 3, thereby fixing horizontal plate 2. Washer 26 increases the area between nut 23 and horizontal plate 2, increases the clamping force between nut 23 and horizontal plate 2, and helps to improve the installation stability of horizontal plate 2. A transverse groove 211 is provided at the end of screw 21 away from C-shaped steel 3. The length direction of transverse groove 211 is perpendicular to the length direction of fixing block 22. The operator can determine the position of fixing block 22 inside C-shaped steel 3 by observing the direction of transverse groove 211. When transverse groove 211 is parallel to the length direction of C-shaped steel 3, the inclined surface of fixing block 22 abuts against the inner wall of C-shaped steel 3. Otherwise, there is no abutment, thereby improving the convenience of the operator to install the transverse plate 2.

[0033] Reference Figure 1 and Figure 2 Screw 21 is coaxially fixed above fixing block 22 with fixing block 25. When screw 21 rotates, fixing block 25 rotates. When the inclined surfaces on both sides of fixing block 22 abut against the inner wall of C-shaped steel 3, fixing block 25 abuts against the open inner wall of C-shaped steel 3, further limiting the rotation of screw 21 along its own axis, thereby improving the installation stability of screw 21 and cross plate 2.

[0034] Reference Figure 1 and Figure 2 A clamp 1 is installed above the horizontal plate 2. The clamp 1 includes two opposing semi-rings 11 and 12. Semi-ring 11 and 12 are connected by bolts 13. Semi-ring 11 is located above semi-ring 12. A threaded post 15 is installed below semi-ring 12. The center of the threaded post 15 is directly opposite to that of semi-ring 12. An installation tube 24 adapted to the threaded post 15 is installed at the upper end of the horizontal plate 2. The threaded post 15 is inserted into the installation tube 24 and threadedly connected to the installation tube 24. The horizontal plate 2 supports the threaded post 15 through the installation tube 24, thereby supporting semi-ring 11 and semi-ring 12. When the operator rotates semi-ring 11 and semi-ring 12, the installation tube 24 guides and limits the threaded post 15.

[0035] Reference Figure 1 and Figure 2Rubber pads 14 are installed on the inner sides of both semi-ring 11 and semi-ring 2. When the pipeline passes between semi-ring 11 and semi-ring 2, semi-ring 11 and semi-ring 2 contact the pipeline through the rubber pads 14. The rubber pads 14 deform to protect the pipeline and reduce the probability of friction damage caused by direct contact between the pipeline and semi-ring 11 and semi-ring 2, which helps to extend the service life of the pipeline.

[0036] The implementation principle of the suspended pipe fixing device in this embodiment is as follows: the operator rotates the fixing block 22 to abut against the inner wall of the C-shaped steel 3 along its two lateral inclined surfaces, and the fixing block 25 abuts against the inner wall of the open opening of the C-shaped steel 3, fixing the screw 21 along its circumferential displacement. Tightening the nut 23 causes the screw 21 to move the fixing blocks 22 and 25 closer to the horizontal plate 2, thereby clamping the C-shaped steel 3 with the fixing blocks 22 and 25 to fix the horizontal plate 2. The horizontal plate 2 then fixes the mounting pipe 24, and the mounting pipe 24 fixes the threaded post. 15. The displacement along the length of C-shaped steel 3 is fixed, thereby fixing the pipe with half ring 11 and half ring 2. When the operator needs to change the position of the pipe, the relative fixation between the horizontal plate 2 and C-shaped steel 3 is released by loosening nut 23 and rotating screw 21, which makes it easier for the operator to slide the horizontal plate 2 along the length of C-shaped steel 3. With half ring 11 and half ring 2 clamped to the pipe, the position of the pipe along the length of C-shaped steel 3 can be adjusted without disassembling and reinstalling clamp 1, thereby improving the convenience of pipe position adjustment. Example 2

[0037] The difference between this embodiment and embodiment 1 is that two opposing arc-shaped plates 111 are interactively connected at the upper end of the semi-ring 11. An arc-shaped groove 116 is provided on the inner wall of the semi-ring 11 along its own length direction. The arc-shaped plates 111 are located in the arc-shaped groove 116 and are slidably connected to the arc-shaped groove 116.

[0038] Reference Figure 3 and Figure 4 Two curved plates are vertically hinged to the same swing arm 112 at their close ends. A second curved plate 113 is vertically hinged to the lower end of the swing arm 112. A cable tie 114 is provided on the swing arm 112. The two ends of the cable tie 114 extend horizontally through the swing arm 112 and cross each other. Both ends of the semi-ring 11 have through holes 115 along its length. The two ends of the cable tie 114 pass through the adjacent through holes 115. The through holes 115 guide and limit the cable tie 114. Both ends of the semi-ring 11 are equipped with tensioning devices 16 along its length. The cable tie 114 passes through the tensioning devices 16. The tensioning devices 16 support and fix the cable tie 114, thereby supporting the pipeline.

[0039] Reference Figure 5 and Figure 6 A circular ring is coaxially fixed on bolt 13. A ring groove, matching the circular ring, is formed at the lower end of half-ring 11. The circular ring abuts against the inner wall of the upper end of the ring groove. Bolt 13 is coaxially rotatably connected to half-ring 11 via the circular ring, thus fixing half-ring 11's vertical displacement. Initially, bolt 13 is not tightened, and a certain distance remains between half-ring 11 and half-ring 12. Cable tie 114, under the action of the pipe and its own weight, moves arc-shaped plate 113 downwards. Arc-shaped plate 113, through swing arm 112, moves arc-shaped plate 111 along the length of arc-shaped groove 116 towards each other, maintaining a certain distance between cable tie 114 and half-rings 11 and 12. This facilitates adjustment and positioning of the pipe before its fixed position by the operator, improving the convenience of pipe position adjustment.

[0040] Reference Figure 3 and Figure 5 The tensioning device 16 includes a fixed plate 161, a sliding plate 162, and a threaded rod 163. The fixed plate 161 is perpendicularly connected to the semi-ring 11. The threaded rod 163 passes through the fixed plate 161 and is threadedly connected to the fixed plate 161. The sliding plate 162 is rotatably connected to one end of the threaded rod 163 that passes through the fixed plate 161. The sliding plate 162 is parallel to the fixed plate 161. A limit rod is installed on the semi-ring 11. The limit rod passes through the sliding plate 162 laterally and is fixedly connected to the fixed plate 161. When the operator rotates the threaded rod 163, the fixed plate 161 supports the threaded rod 163. The threaded rod 163 drives the sliding plate 162 to slide along the length of the limit rod and slides with the limit rod. The limit rod guides the movement of the sliding plate 162.

[0041] Reference Figure 5 and Figure 6 A one-way buckle is fixedly installed on the sliding plate 162. The one-way buckle includes an arc-shaped piece 1622 and a round rod 1621. The arc-shaped piece 1622 is installed on the side of the sliding plate 162 facing away from the fixed plate 161. The cable tie 114 passes through the middle of the arc-shaped piece 1622 and the sliding plate 162 from bottom to top. The distance between the arc-shaped piece 1622 and the sliding plate 162 gradually increases along the insertion direction of the cable tie 114. The round rod 1621 is rolled between the arc-shaped piece 1622 and the sliding plate 162. The cable tie 114 extends along its length... The cable tie 114 is positioned between the round rod 1621 and the sliding plate 162. After the cable tie 114 is tightened, the round rod 1621 is positioned at the insertion point of the cable tie 114 and in the slot. The round rod 1621 fixes the cable tie 114 by the friction between itself and the arc-shaped piece 1622 and the friction between the round rod 1621 and the cable tie 114. The cable tie 114 is further fixed by being inserted into the slot, reducing the probability of the cable tie 114 retracting.

[0042] Reference Figure 5 and Figure 6 The operator rotates the threaded rod 163 to move the sliding plate 162 closer to the fixed plate 161. The fixed plate 161 moves the cable tie 114 closer to the fixed plate 161 through the one-way buckle, so that the two ends of the cable tie 114 move away from each other along the length direction, and tighten the cable tie 114 a second time, further improving the stability of the cable tie 114 after tightening, thereby improving the installation stability of the pipeline.

[0043] Reference Figure 5 and Figure 6 After the cable tie 114 tightens the pipe, the operator rotates the bolt 13, causing the bolt 13 to move the first half ring 11 closer to the second half ring 12. After both the first half ring 11 and the second half ring 12 come into contact with the cable tie 114, the pipe is fixed by the second half ring 11 and the second half ring 12. The second arc plate 113 and the first arc plate 111 are both located in the arc groove 116. The arc groove 116 accommodates the first arc plate 111 and the second arc plate 113, reducing the probability that the second arc plate 113 will affect the fixation of the pipe, which is conducive to improving the installation stability of the pipe.

[0044] Reference Figure 3 A rotating ring 4 is coaxially rotatably connected to the mounting pipe 24. Two telescopic rods 41 are mounted on the rotating ring 4, arranged opposite each other. The end of the telescopic rod 41 away from the rotating ring 4 is fixedly connected to half-ring 12. The mounting pipe 24 supports the rotating ring 4, and the telescopic rods 41 connect the rotating ring 4 and half-ring 12, so that when half-ring 11 rotates, the rotating ring 4 rotates through the telescopic rods 41. A fixing rod 42 is mounted on the rotating ring 4. The fixing rod 42 is inserted into the rotating ring 4 radially and threadedly connected to the rotating ring 4. By rotating the fixing rod 42, the operator makes the fixing rod 42 abut against the mounting pipe 24, thereby fixing the displacement of the rotating ring 4 along its own circumference, and thus fixing the displacement of half-ring 11 along the circumference of the mounting pipe 24, which helps to improve the stability of half-ring 11 and half-ring 12 after rotation.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
