Description

Technical Field

[0001] The present invention relates to the field related to pipeline installation, and in particular to a support and hanger device for installing a fire protection pipeline. Background Art

[0002] Building mechanical and electrical installation supports and hangers are core load-bearing structures used to support and secure pipes, air ducts, bridges, and other facilities. Their core function is to safely transfer equipment loads to the main building structure through rigid connections, while maintaining the spatial positioning accuracy of the mechanical and electrical pipelines. Taking fire protection pipe installation as an example, the typical process includes: first, using hot-dip galvanized channel steel to make a door-shaped support, which is anchored to the structural top plate through laser positioning and expansion bolts; then, using hydraulic lifting equipment, the pipe is raised to the design elevation and the pipe end is connected to the support. Lateral support is then completed through lateral translation; finally, a dual-support collaborative fixing mode is adopted, and the pipe is tightened with clamps to ensure the stability of the fire protection pipe placement.

[0003] The above information clearly reveals that during the pipeline installation phase, the lifting equipment required repeated adjustments to achieve multi-directional docking. The average installation of a single pipeline required four to six equipment relocations. During tightening operations, operators frequently had to climb ladders to complete high-altitude work, and the installation of a single pipe clamp was time-consuming. This operating model not only resulted in over 70% of the work being consumed by equipment adjustment and personnel movement, but also significantly increased the risk of falls from height, reducing overall construction efficiency. Summary of the Invention

[0004] The present invention proposes a fire protection pipe installation support and hanger device, which has the advantages of easy installation and elastic fixation of the bracket, and is used to solve the problems of complicated procedures and high risks of high-altitude fastening operations in the traditional fire protection pipe installation process mentioned in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solutions: a fire-fighting pipe installation support and suspension device, comprising: a mounting frame, on the bottom of which an auxiliary pressure frame and a main pressure frame pushed downward by a tightening spring are symmetrically installed, and release grooves are provided at the ends of the auxiliary pressure frame and the main pressure frame; a support base, mounted on the bottom of the mounting frame, on which a reset frame is mounted, and a reset tension spring is connected between the reset frame and the mounting frame, and the reset tension spring is utilized to enable the support base to reach the sides of the auxiliary pressure frame and the main pressure frame; after the auxiliary pressure frame and the main pressure frame move upward and align the release grooves with the support base, the support base is further moved to the bottom of the mounting frame.

[0006] Furthermore, a positioning base for limiting the position of the pipe is installed in the middle of the surface of the support base.

[0007] Furthermore, a limiting block is installed at the end of the support base, and a limited motion groove is symmetrically opened on the side.

[0008] Furthermore, a piston rod connected to the reset frame is movably installed in the middle of the support base, an anti-slip top block is fixedly installed on the end of the piston rod, and a stepped groove is opened on the side of the main pressure frame.

[0009] Furthermore, the groove depth of the stepped groove increases equally from bottom to top.

[0010] Furthermore, a wedge-shaped slider is installed on the side of the auxiliary pressure frame.

[0011] Furthermore, a piston cavity is provided inside the support base, and a damping hole and a one-way air intake valve communicating with the piston cavity are provided on the support base.

[0012] The present invention has the following beneficial effects:

[0013] The present invention provides a fire protection pipe installation support and hanger device that utilizes a spring linkage mechanism to facilitate rapid installation of fire protection pipes. During installation, a lifting device pushes the pipe into the openings of the auxiliary and main pressure frames. Once the pipe is fully seated, the linkage mechanism releases the obstruction on the support base, which automatically resets to the position below the pipe under the action of a return spring, forming a support surface. After the lifting device is lowered, the weight of the pipe is borne by the support base, while the auxiliary and main pressure frames, acting under the action of a tightening spring, press against the upper surface of the pipe, completing the fixation.

[0014] The device realizes an automated installation process through mechanical linkage. The entire process does not require frequent manual adjustment of the support position. The operator only needs to control the lifting equipment to complete most of the installation steps, which greatly simplifies the installation process, effectively shortens the installation time and reduces the installation cost.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] For example 1, please refer to Figure 1 It can be seen that the mounting frame 1 is a rectangular frame constructed of hot-dip galvanized channel steel, wherein the mounting frame 1 has a downward opening. The auxiliary pressure frame 2 and the main pressure frame 3 are symmetrically installed at the bottom of the mounting frame 1. The auxiliary pressure frame 2 and the main pressure frame 3 have the same structure and are both "n" shaped. Figure 1 It can also be seen that nuts are installed at the ends of the auxiliary pressure frame 2 and the main pressure frame 3, and a tightening spring 4 is provided between the nuts and the mounting frame 1 and located below the mounting frame 1. Under normal circumstances, the nuts will move vertically downwards under the elastic force until both the auxiliary pressure frame 2 and the main pressure frame 3 have descended to the bottom limit position, as shown in FIG. Figure 1 As shown, both the auxiliary pressure frame 2 and the main pressure frame 3 have downward-facing openings at their bases, primarily for accommodating firefighting pipes. During installation, the firefighting pipes are lifted vertically upward using a lifting device, such as a hydraulic lift. Once the firefighting pipes enter the auxiliary pressure frame 2 and the main pressure frame 3 and move further upward, they push the auxiliary pressure frame 2 and the main pressure frame 3 upward synchronously, simultaneously elastically compressing the tightening spring 4.

[0029] Combine Figure 1 and Figure 2 As shown, a support base 6 is movably mounted on the bottom of the mounting frame 1, and the support base 6 can only move horizontally back and forth along the bottom of the mounting frame 1. In addition, a reset frame 9 is mounted on the support base 6, and the reset frame 9 is movably connected to the bottom of the mounting frame 1. A reset spring 900 is fixedly connected between the reset frame 9 and the bottom of the mounting frame 1. Under normal conditions, the elastic force of the reset spring 900 causes the end of the support base 6 to abut against the side of the auxiliary pressure frame 2 and the main pressure frame 3. Figure 3 and Figure 4 It can be seen that the ends of the auxiliary pressure frame 2 and the main pressure frame 3 are both provided with a release groove 5 close to the side of the support base 6. Figure 6 As shown, under normal circumstances, the auxiliary pressure frame 2 and the main pressure frame 3 move downward to the bottom limit under the elastic force of the tightening spring 4. At the same time, when the reset spring 900 pulls the reset frame 9, it forces the end of the support base 6 to press against the side of the auxiliary pressure frame 2 / main pressure frame 3.

[0030] When the lifting equipment transports the fire pipe to the auxiliary pressure frame 2 and the main pressure frame 3 and pushes them upward synchronously, the auxiliary pressure frame 2 and the main pressure frame 3 move upward synchronously. Figure 8 As shown in FIG, the release slots 5 on the auxiliary pressure frame 2 and the main pressure frame 3 move to the end of the support base 6, thereby releasing the restriction on the movement of the support base 6. Figure 9 As shown, under the elastic force of the return spring 900, the support base 6 moves to the bottom of the pipeline. Figure 1 It can be clearly seen that the middle part of the surface of the support base 6 is provided with a positioning base 7 fastened with bolts, and the surface of the positioning base 7 is provided with a "V"-shaped limiting groove, which can be used to limit the fire pipe.

[0031] Finally, when the support base 6 is fully extended to the bottom of the mounting frame 1, the positioning base 7 is located below the fire protection pipe. The operator simply uses the lifting equipment to release the fire protection pipe, and the descending fire protection pipe will be pressed against the positioning base 7 and restrained by the positioning base 7. At the same time, the auxiliary pressure frame 2 and the main pressure frame 3 continue to descend under the elastic force of the tightening spring 4. Eventually, the auxiliary pressure frame 2 and the main pressure frame 3 are pressed against the fire protection pipe, thus tightening the fire protection pipe.

[0032] It should be noted that during the actual installation process, a fire protection pipe requires at least two mounting brackets 1 for support and fixation. Therefore, when a straight fire protection pipe is moved upward using a lifting device, it must pass through both mounting brackets 1 simultaneously to achieve the above-mentioned function. Finally, the support bases 6 on the two mounting brackets 1 can support and limit the fire protection pipe. Moreover, with the auxiliary pressure bracket 2 and the main pressure bracket 3 both pressing on the fire protection pipe, the fire protection pipe is tightened.

[0033] The second embodiment is a further improvement on the basis of the first embodiment. Figure 1 It can be seen that there is a limiting block installed by bolts at the end of the support base 6 and in the direction away from the mounting frame 1. Figure 9 It can be seen from the figure that when the support base 6 is fully inserted into the bottom of the mounting frame 1, the limiting block fixed at its end will reach the outer side of the mounting frame 1, thereby effectively limiting the length of the support base 6 extending into the interior of the mounting frame 1. Figure 1 and Figure 5 As can be seen, the support base 6 has symmetrically defined limiting grooves 600 on its sides. These semicircular grooves have diameters corresponding to those of the auxiliary pressure frame 2 and the main pressure frame 3. When the support base 6 is fully inserted into the bottom of the mounting frame 1, the limiting grooves 600 move to the release grooves 5 on the auxiliary pressure frame 2 and the main pressure frame 3. As the auxiliary pressure frame 2 and the main pressure frame 3 descend, they both pass through the limiting grooves 600. The sides of the auxiliary pressure frame 2 and the main pressure frame 3 effectively restrict the movement of the support base 6, ensuring that, after installation, the support base 6 cannot freely move horizontally at the bottom of the mounting frame 1.

[0034] Not only that, combined with Figure 5 It can be seen that a piston rod 8 is movably mounted in the middle of the support base 6, and the piston rod 8 is fixedly connected to the reset frame 9, so that the reset frame 9 can drive the piston rod 8 to move horizontally synchronously. Generally speaking, a spring is provided between the support base 6 and the reset frame 9 and is sleeved on the outside of the piston rod 8. Figure 5 It can also be seen that an anti-slip block 10 is fixedly mounted on the end of the piston rod 8. The anti-slip block 10 is in the shape of a rectangular parallelepiped, and cylindrical rods inserted into the support base 6 are provided at both ends of the anti-slip block 10, thereby limiting the anti-slip block 10 to horizontal reciprocating movement along the support base 6. Under normal circumstances, when the anti-slip block 10 abuts the outer side of the auxiliary pressure frame 2 and the main pressure frame 3, since a spring is also provided between the support base 6 and the reset frame 9, the support base 6 is always pushed against the anti-slip block 10 by the spring's elastic force.

[0035] Correspondingly, from Figure 4 As can be seen in the figure, the main pressure frame 3 has a stepped groove 300 on the side away from the release groove 5. The depth of the stepped groove 300 increases uniformly from bottom to top. The advantage of this design is that when the lifting equipment pushes the fire pipe into the auxiliary pressure frame 2 and the main pressure frame 3, the auxiliary pressure frame 2 and the main pressure frame 3 release the movement restriction on the anti-dropping block 10.

[0036] Afterwards, under the pull of the reset frame 9, the support base 6 and the anti-dropping block 10 are synchronously moved to the bottom of the mounting frame 1, and the limiting block on the support base 6 finally abuts against the outer side of the mounting frame 1. The reset spring 900 further moves by pulling the reset frame 9, and the piston rod 8 pushes the anti-dropping block 10 further toward the stepped groove 300 until the anti-dropping block 10 abuts against the stepped groove 300. Figure 1 It can be seen that when the lifting equipment releases its support for the fire pipe, the main pressure frame 3 is pushed downward by the elastic force of the tightening spring 4 until the main pressure frame 3 is pressed on the fire pipe. In addition, as the step groove 300 continues to move downward, the anti-slip block 10 will continue to cross the step groove 300. It should be noted that in order to prevent the anti-slip block 10 from hitting the step groove 300, the auxiliary pressure frame 2 will hinder its movement. Figure 2 It can be clearly seen that the end of the auxiliary pressure frame 2 is set to be semicircular, which ensures that the anti-slipping top block 10 will not contact the auxiliary pressure frame 2 after it reaches the stepped groove 300.

[0037] Finally, when the main pressure frame 3 is completely pressed on the fire-fighting pipe, the anti-slip top block 10 presses against the stepped groove 300 to limit the upward movement of the main pressure frame 3, thereby ensuring that the fire-fighting pipe is fixed for a long time. The anti-slip top block 10 presses against the stepped groove 300 to lock the main pressure frame 3 upward, ensuring that the main pressure frame 3 is always pressed tightly against the fire-fighting pipe.

[0038] Example 3 is a supplement to Example 2. Please refer to Figure 3 It can be seen that the auxiliary pressure frame 2 has a wedge-shaped slider 200 on the side that is fastened by bolts and is relatively far away from the release groove 5. The side of the wedge-shaped slider 200 is in the shape of a rectangular parallelepiped with a sloped top. When the auxiliary pressure frame 2 and the main pressure frame 3 are pushed upward to the top by the fire pipe, the support base 6 will be inserted into the bottom of the mounting frame 1, but will be blocked by the wedge-shaped slider 200, causing the anti-slip block 10 to first hit the wedge-shaped slider 200 and not contact the stepped groove 300. After the fire pipe is placed, the anti-slip block 10 will not directly hit the stepped groove 300 to lock it, ensuring that the fire pipe placed for the first time can be adjusted to a certain extent after position deviation.

[0039] Furthermore, based on Figure 5It can be seen that a piston cavity 601 is provided inside the support base 6, wherein the piston on the piston rod 8 is located in the piston cavity 601 and can move relatively therewith. A damping hole 602 is provided on the surface of the support base 6. When the piston on the piston rod 8 squeezes the airflow in the piston cavity 601, the airflow in the piston cavity 601 can be buffered by the damping hole 602, thereby relatively slowing down the movement of the anti-detachment top block 10 to the right. In addition, a one-way air intake valve 603 connected to the piston cavity 601 is fixedly installed at the bottom of the support base 6, which is used to quickly replenish the external airflow into the piston cavity 601.

[0040] During actual use, when the auxiliary pressure frame 2 and the main pressure frame 3 are pushed upward by the fire pipe, the release groove 5 on the auxiliary pressure frame 2 and the main pressure frame 3 will release the movement restriction on the support base 6. Under the elastic force of the reset tension spring 900, the support base 6 and the anti-slip block 10 will move to the bottom of the mounting frame 1. At this time, the restriction block on the outside of the support base 6 will abut the side of the mounting frame 1, and the anti-slip block 10, under the action of the reset frame 9 pushing the piston rod 8, will first abut the outer side of the wedge-shaped slider 200. The anti-slip block 10 is now located on the plane of the wedge-shaped slider 200. At the same time, because the support base 6 is restricted by the mounting frame 1, when the anti-slip block 10 moves toward the side of the auxiliary pressure frame 2, the pressure in the piston chamber 601 will decrease, and air will be quickly replenished using the one-way air inlet valve 603.

[0041] When the support base 6 is fully inserted into the mounting frame 1 and the anti-slip block 10 abuts the flat surface of the wedge-shaped slider 200, the lifting equipment no longer supports the fire protection pipe. The auxiliary pressure frame 2 and the main pressure frame 3 move downward synchronously under the elastic force of the tightening spring 4. The auxiliary pressure frame 2 and the main pressure frame 3 are inserted into the limiting groove 600 to limit the horizontal movement of the support base 6. Furthermore, as the auxiliary pressure frame 2 drives the main pressure frame 3 downward, the inclined surface of the auxiliary pressure frame 2 abuts the anti-slip block 10 and squeezes the piston chamber 601. The pressurized air in the piston chamber 601 slowly flows out of the damping hole 602.

[0042] Therefore, after the lifting equipment removes the lifting force, the main pressure frame 3 will first follow the fire protection pipe downward and use the main pressure frame 3 to pre-press on the pipe. During this process, since the main pressure frame 3 can still move up and down, the pre-pressed pipe can be used to determine whether it is placed in place. When the horizontal position of the pipe is adjusted, the lifting equipment can be used directly to adjust it.

[0043] As the tightening spring 4 pushes the auxiliary pressure frame 2 to move downward, the wedge-shaped slider 200 will pass over the anti-slip top block 10. The side of the auxiliary pressure frame 2 on which the wedge-shaped slider 200 is installed is semicircular, so that after the wedge-shaped slider 200 is separated from the anti-slip top block 10, the anti-slip top block 10 is pushed by the piston rod 8 and moves toward the auxiliary pressure frame 2 and the main pressure frame 3. The anti-slip top block 10 will first contact the stepped groove 300 and leave a distance between the top of the anti-slip top block 10 and the auxiliary pressure frame 2 to prevent the side of the auxiliary pressure frame 2 from obstructing the contact limit between the stepped groove 300 and the anti-slip top block 10.
