Description

Technical Field

[0001] The present invention relates to the technical field related to pipeline installation, and particularly relates to a support and hanger device for fire pipeline installation. Background Technique

[0002] The support and hanger for building mechanical and electrical installation is the core load-bearing structure for supporting and fixing pipelines, air ducts, cable trays and other facilities. Its core function is to safely transfer the equipment load to the building main structure through rigid connection, and at the same time maintain the spatial positioning accuracy of the mechanical and electrical pipelines. Taking the installation of fire pipelines as an example, the typical technological process includes: first, making a portal bracket with hot-dip galvanized channel steel, and anchoring it to the structural roof through laser positioning and expansion bolts; then using a hydraulic lifting device to lift the pipeline to the designed elevation, and realizing the butt joint between the pipeline end and the bracket, and then completing the lateral support through horizontal translation; finally, adopting a double-bracket collaborative fixing mode, and using clamps to fasten the pipeline to ensure the stability of the placement of the fire pipeline.

[0003] It is not difficult to find from the above content that during the pipeline positioning stage, the position of the lifting device needs to be adjusted repeatedly to achieve multi-directional butt joint. On average, 4-6 equipment displacements are required for the installation of a single pipeline; during the fastening operation, the operator needs to climb the ladder frequently to complete the high-altitude operation, and the installation of the clamp for a single pipeline takes a long time. This operation mode not only results in more than 70% of the working hours being consumed in the equipment position adjustment and personnel movement links, but also significantly increases the risk of falling from a height, reducing the overall construction efficiency. Summary of the Invention

[0004] The present invention proposes a support and hanger device for fire pipeline installation, which has the advantages of being easy to install and elastically fixing the support, and is used to solve the problems of cumbersome procedures and high risk of high-altitude fastening operation existing in the traditional fire pipeline installation process mentioned in the above background technique.

[0005] To achieve the above object, the present invention adopts the following technical scheme: A support and hanger device for fire pipeline installation, comprising: an installation frame, on the bottom of which a secondary pressure frame and a main pressure frame pushed downward by a fastening spring are symmetrically installed, and release grooves are opened at the ends of the secondary pressure frame and the main pressure frame; a support base, installed at the bottom of the installation frame, a reset frame is installed on the support base, and a reset tension spring is connected between the reset frame and the installation frame, and the support base is made to abut against the sides of the secondary pressure frame and the main pressure frame by using the reset tension spring; after the secondary pressure frame and the main pressure frame move upward and the release grooves are aligned with the support base, the support base further moves to the bottom of the installation frame.

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

[0007] Further, a limiting block is installed at the end of the support base, and limited movement grooves are symmetrically opened on the side.

[0008] Further, a piston rod connected to the reset frame is movably installed in the middle of the support base. An anti - detachment top block is fixedly installed at the end of the piston rod, and a stepped groove is formed on the side of the main pressure frame.

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

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

[0011] Further, a piston chamber is formed inside the support base, and a damping hole and a one - way air inlet valve communicating with the piston chamber are provided on the support base.

[0012] The present invention has the following beneficial effects: A fire - fighting pipeline installation support and hanger device provided by the present invention realizes the rapid installation of fire - fighting pipelines through a spring linkage mechanism. During installation, a lifting device jacks the pipeline into the opening grooves of the auxiliary pressure frame and the main pressure frame. When the pipeline is completely in place, the linkage mechanism releases the blockage of the support base, and the support base automatically resets under the action of the reset tension spring to form a supporting surface below the pipeline. After the lifting device descends, the weight of the pipeline is borne by the support base. At the same time, the auxiliary pressure frame and the main pressure frame compress the upper surface of the pipeline under the action of the fastening spring to complete the fixation.

[0013] This device realizes an automated installation process through mechanical linkage. During the whole process, there is no need for manual frequent adjustment of the support position. The operator only needs to control the lifting device to complete most of the installation steps, which greatly simplifies the installation process, effectively shortens the installation time, and reduces the installation cost.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0018] Example 1, please refer to Figure 1 It can be seen that the outer shape of the mounting frame 1 is a rectangular frame built by hot - dip galvanized channel steel. Among them, 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 in the shape of "n". From 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 fastening spring 4 located below the mounting frame 1 is arranged between the nuts and the mounting frame 1. In the normal state, the nuts are pushed by the elastic force and move vertically downward until the auxiliary pressure frame 2 and the main pressure frame 3 both move downward to the bottom limit position, as Figure 1 shown. At this time, it can be seen that both the auxiliary pressure frame 2 and the main pressure frame 3 have downward openings at the bottom, and these openings are mainly used to place the fire - fighting pipeline. During actual installation, the fire - fighting pipeline is vertically lifted upward by a lifting device, such as a hydraulic lift. When the fire - fighting pipeline enters the auxiliary pressure frame 2 and the main pressure frame 3 and moves further upward, the fire - fighting pipeline will push the auxiliary pressure frame 2 and the main pressure frame 3 to move upward synchronously and simultaneously elastically compress the fastening spring 4.

[0019] Combined with Figure 1 and Figure 2As shown, a support base 6 is movably installed at the bottom of the mounting bracket 1, and the support base 6 can only move horizontally back and forth along the bottom of the mounting bracket 1. Moreover, a reset frame 9 is installed on the support base 6, and the reset frame 9 is movably connected to the bottom of the mounting bracket 1. A reset spring 900 is fixedly connected between the reset frame 9 and the bottom of the mounting bracket 1. Under normal conditions, under the pulling force of the reset spring 900, the end of the support base 6 abuts against the sides of the auxiliary pressing frame 2 and the main pressing frame 3. Combined with Figure 3 and Figure 4 it can be seen that release grooves 5 are provided at the ends of the auxiliary pressing frame 2 and the main pressing frame 3 on the side close to the support base 6. Combined with Figure 6 As shown, under normal conditions, the auxiliary pressing frame 2 and the main pressing frame 3 are pushed downward to the bottom limit under the elastic force of the fastening spring 4. At the same time, when the reset spring 900 pulls the reset frame 9, it will force the end of the support base 6 to abut against the side of the auxiliary pressing frame 2 / main pressing frame 3.

[0020] When the lifting device transports the fire pipeline to the auxiliary pressing frame 2 and the main pressing frame 3 and synchronously pushes the two upward, the auxiliary pressing frame 2 and the main pressing frame 3 move upward synchronously. When the auxiliary pressing frame 2 and the main pressing frame 3 both move to the upper limit, as Figure 8 shown, the release grooves 5 on the auxiliary pressing frame 2 and the main pressing frame 3 move to the end of the support base 6, thus releasing the restriction on the movement of the support base 6. After that, as Figure 9 shown, under the pulling force of the reset spring 900, the support base 6 moves to the lower side of the pipeline. Moreover, it can be clearly seen from Figure 1 that there is a positioning base 7 fastened by bolts in the middle of the surface of the support base 6, and a "V" - shaped limiting groove is provided on the surface of the positioning base 7, and the fire pipeline can be limited by using this groove.

[0021] Finally, when the support base 6 completely extends into the bottom of the mounting bracket 1, at this time, the positioning base 7 is located under the fire pipeline. The operator only needs to use the lifting device to release the lifting of the fire pipeline, and the descending fire pipeline will be pressed on the positioning base 7 and limited by the positioning base 7. At the same time, the auxiliary pressing frame 2 and the main pressing frame 3 continuously descend under the elastic force of the fastening spring 4, and finally both the auxiliary pressing frame 2 and the main pressing frame 3 are pressed on the fire pipeline to realize the fastening of the fire pipeline.

[0022] It should be noted that during the actual installation process, at least two mounting brackets 1 are required to support and fix one fire pipeline. Therefore, when a straight fire pipeline moves upward by using the lifting device, it needs to pass through two mounting brackets 1 simultaneously and achieve the above - mentioned content. Finally, the support bases 6 on the two mounting brackets 1 can support and limit the fire pipeline, and, based on the fact that both the auxiliary pressing frame 2 and the main pressing frame 3 are pressed above the fire pipeline, the fastening of the fire pipeline is realized.

[0023] Embodiment 2 is a further improvement based on Embodiment 1. Please refer to Figure 1 As can be seen, there is a limiting block bolted and installed at the end of the support base 6 and in the direction away from the mounting frame 1. From Figure 9 it can be seen that when the support base 6 is completely inserted into the bottom of the mounting frame 1, the limiting block fixed to its end will abut against the outer side of the mounting frame 1, thereby effectively restricting the length of the support base 6 extending into the mounting frame 1. At the same time, from Figure 1 and Figure 5 it can be seen that the limiting slots 600 are symmetrically formed on the side of the support base 6. The limiting slots 600 are semi-circular slots, and the diameter of this slot corresponds to the diameter of the auxiliary pressing frame 2 / the main pressing frame 3. When the support base 6 is completely inserted into the bottom of the mounting frame 1, the limiting slots 600 will move to the release slots 5 on the auxiliary pressing frame 2 / the main pressing frame 3. As the auxiliary pressing frame 2 and the main pressing frame 3 move downward, both the auxiliary pressing frame 2 and the main pressing frame 3 pass through the limiting slots 600. The sides of the auxiliary pressing frame 2 and the main pressing frame 3 can effectively restrict the movement of the support base 6, ensuring that after the support base 6 is installed, it cannot move freely horizontally at the bottom of the mounting frame 1.

[0024] Moreover, in combination with Figure 5 it can be seen that a piston rod 8 is movably installed in the middle of the support base 6, and the piston rod 8 is fixedly connected to the reset frame 9, so as to realize that the reset frame 9 can drive the piston rod 8 to move horizontally synchronously. Generally, a spring sleeved on the outer side of the piston rod 8 is provided between the support base 6 and the reset frame 9. From Figure 5 it can also be seen that an anti-drop top block 10 is fixedly installed at the end of the piston rod 8. The shape of the anti-drop top block 10 is a cuboid, and cylindrical rods inserted into the support base 6 are provided at both ends of the anti-drop top block 10, thereby restricting the anti-drop top block 10 to only move horizontally back and forth along the support base 6. Under normal conditions, when the anti-drop top block 10 abuts against the outer sides of the auxiliary pressing frame 2 and the main pressing frame 3, since a spring is also provided between the support base 6 and the reset frame 9, driven by the elastic force of the spring, the support base 6 will always abut against the anti-drop top block 10.

[0025] Correspondingly, from Figure 4 it can be seen that a stepped groove 300 is formed on the side of the main pressing frame 3 on the side away from the release slot 5, and the groove depth of the stepped groove 300 increases equally in the direction from bottom to top. The advantage of this design is that when the lifting device presses the fire pipeline against the auxiliary pressing frame 2 and the main pressing frame 3, the auxiliary pressing frame 2 and the main pressing frame 3 release the movement restriction on the anti-drop top block 10.

[0026] After that, under the pulling of the reset frame 9, the support base 6 and the anti-disengagement top 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 tension spring 900 further moves by pulling the reset frame 9, and according to the piston rod 8, the anti-disengagement top block 10 is pushed further closer to the stepped groove 300 until the anti-disengagement top block 10 abuts against the stepped groove 300. As can be seen from Figure 1 When the lifting device releases the support for the fire pipeline, the main pressure frame 3 will continuously move downward under the elastic force of the fastening spring 4 until the main pressure frame 3 presses on the fire pipeline. Moreover, since the stepped groove 300 continuously moves downward, the anti-disengagement top block 10 will continuously cross the stepped groove 300. It should be noted that in order to prevent the auxiliary pressure frame 2 from hindering the movement of the anti-disengagement top block 10 when it abuts against the stepped groove 300, refer to Figure 2 It can be clearly seen that the end of the auxiliary pressure frame 2 is semicircular, ensuring that after the anti-disengagement top block 10 abuts against the stepped groove 300, the anti-disengagement top block 10 will not contact the auxiliary pressure frame 2.

[0027] Finally, when the main pressure frame 3 is completely pressed on the fire pipeline, the anti-disengagement top block 10 abuts against the stepped groove 300, thereby restricting the upward movement of the main pressure frame 3. During the long-term fixation of the fire pipeline, the anti-disengagement top block 10 abuts against the stepped groove 300 to achieve the upward locking of the main pressure frame 3, ensuring that the main pressure frame 3 always tightly presses on the fire pipeline.

[0028] Example three is a supplement to example two. Please refer to Figure 3 It can be seen that there is a wedge-shaped slider 200 on the side of the auxiliary pressure frame 2 that is bolt-fastened and relatively far from the release groove 5. The side of the wedge-shaped slider 200 is rectangular in shape and has an inclined surface at the top. When the auxiliary pressure frame 2 and the main pressure frame 3 are pushed upward by the fire pipeline until the top, the support base 6 will be inserted into the bottom of the mounting frame 1. However, blocked by the wedge-shaped slider 200, the anti-disengagement top block 10 will first abut against the wedge-shaped slider 200 and will not contact the stepped groove 300. After the fire pipeline is placed, the anti-disengagement top block 10 will not directly abut against the stepped groove 300 for locking, ensuring that the initially placed fire pipeline can be adjusted to a certain extent due to position deviation.

[0029] Furthermore, according to Figure 5It can be seen that a piston chamber 601 is provided inside the support base 6. Among them, the piston on the piston rod 8 is located in the piston chamber 601 and can move relatively. A damping hole 602 is provided on the surface of the support base 6. When the piston on the piston rod 8 squeezes the air flow in the piston chamber 601, the air flow in the piston chamber 601 can be buffered by using the damping hole 602, so that the movement speed of the anti-disengagement top block 10 to the right is relatively slowed down. Moreover, a one-way intake valve 603 communicating with the piston chamber 601 is fixedly installed at the bottom of the support base 6, and the one-way intake valve 603 is used to quickly supplement the external air flow into the piston chamber 601.

[0030] During the actual application process, when the auxiliary pressure frame 2 and the main pressure frame 3 are continuously pushed upward by the fire pipeline, the fastening springs 4 on the auxiliary pressure frame 2 and the main pressure frame 3 will release the movement restriction on the anti-disengagement top block 10. Under the elastic force of the reset tension spring 900, the support base 6 and the anti-disengagement top block 10 are moved to the bottom of the mounting frame 1. At this time, the limiting block on the outside of the support base 6 will abut against the side of the mounting frame 1, and the anti-disengagement top block 10 will first abut against the outer side of the wedge-shaped slider 200 under the action of the reset frame 9 pushing the piston rod 8. The anti-disengagement top block 10 is located on the plane of the wedge-shaped slider 200 at this time. At the same time, since the support base 6 is restricted by the mounting frame 1, when the anti-disengagement top block 10 moves toward the side of the auxiliary pressure frame 2, the pressure in the piston chamber 601 will decrease, and the one-way intake valve 603 will be used to quickly supplement air.

[0031] When the support base 6 is completely inserted into the mounting frame 1 and the anti-disengagement top block 10 abuts against the flat part on the wedge-shaped slider 200, as the lifting device no longer provides support for the fire pipeline, the auxiliary pressure frame 2 and the main pressure frame 3 move downward synchronously under the elastic force of the fastening spring 4, and 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. Moreover, as the auxiliary pressure frame 2 drives the main pressure frame 3 to move downward, the inclined surface on the auxiliary pressure frame 2 will abut against the anti-disengagement top block 10 and squeeze the piston chamber 601. After the air in the piston chamber 601 is compressed, it will slowly flow out from the damping hole 602.

[0032] Therefore, after the lifting force of the lifting device is removed, the main pressure frame 3 will first follow the fire pipeline downward and pre-press on the pipeline by using the main pressure frame 3. During this process, since the main pressure frame 3 can still move up and down, it can be judged whether the pipeline is placed in place by using the pre-pressed pipeline. When the horizontal position of the pipeline is adjusted, the lifting device can be directly used for adjustment.

[0033] As the fastening spring 4 pushes the auxiliary pressure frame 2 to continuously move downward, the wedge-shaped slider 200 will cross over the anti-disengagement top block 10, from Figure 3It can be seen that the side part of the auxiliary pressure frame 2 where the wedge-shaped slider 200 is installed is semi-circular. Such a design enables that after the wedge-shaped slider 200 is disengaged from the anti-disengagement top block 10, the anti-disengagement top block 10 is pushed by the piston rod 8 and moves towards the auxiliary pressure frame 2 and the main pressure frame 3. The anti-disengagement top block 10 will first contact the stepped groove 300, and a gap is left between the top of the anti-disengagement top block 10 and the auxiliary pressure frame 2 to prevent the side part of the auxiliary pressure frame 2 from hindering the contact and limitation between the stepped groove 300 and the anti-disengagement top block 10.
