Description

Technical Field

[0001] This utility model relates to the field of pipeline adjustment technology, and more specifically, to a rapid adjustment structure for fire sprinkler riser pipes. Background Technology

[0002] Sprinkler pipes are commonly used in factories, residential buildings, basements, and tunnels. They are basically composed of horizontal pipes arranged along the direction of the building, with tees installed at intervals on the horizontal pipes. The side openings of the tees are connected to vertical branch pipes. Current construction methods mostly adopt "pre-installation on the ground - installation at height": first, the tees are connected to the horizontal pipes in sections on the ground, then hoisted and fixed, and finally the vertical branch pipes are installed one by one.

[0003] The problem is that it is difficult to accurately ensure that the orientation of multiple tees is consistent during pre-installation, relying mainly on visual inspection and temporary marking. Due to the influence of pipe section self-weight torsion, thread starting angle, and support errors, the tees often deviate after being hoisted into place, causing misalignment of the verticality, elevation, and equipment of the branch pipes. If the orientation is corrected at a height by back-tightening and re-tightening, it is easy to damage the seal between the tee and the horizontal pipe, leading to leakage risks, increased construction time, and increased safety hazards for working at height. Utility Model Content

[0004] The purpose of this utility model is to provide a quick adjustment structure for fire sprinkler riser pipes, which can adjust and fix the tee in a uniform direction during the ground assembly stage, thereby ensuring consistent installation of riser pipes, avoiding the risk of leakage caused by secondary tightening, and effectively improving the overall installation efficiency.

[0005] This utility model is achieved through the following technical solution:

[0006] A quick-adjustment structure for fire sprinkler riser pipes includes:

[0007] A bracket, on which multiple fixing clamps are provided along the length direction, the fixing clamps being used to allow the horizontal tube to pass through and to fix the horizontal tube;

[0008] An infrared emitter is mounted on one side of a bracket and is used to emit a strip of light. The strip of light forms a light path in a vertical direction and illuminates the tee. When the tee is rotated so that the casting line on its outer wall coincides with the vertical light path, the side opening of the tee is in a vertical state.

[0009] An adjustment assembly is provided, on which both the fixing clamp and the infrared emitter are mounted. The adjustment assembly can adjust the height of the fixing clamp and the infrared emitter and fix them after adjustment.

[0010] Furthermore, the fixing clamp includes a base, a clamp frame, a lifting screw, an upper clamping blade, and a lower clamping blade. The clamp frame is arranged in a gate shape and is mounted on the base. The lifting screw is connected to the clamp frame along a vertical thread. The upper clamping blade is disposed on the output end of the lifting screw. The lower clamping blade is fixedly disposed on the base. The upper clamping blade and the lower clamping blade are arranged vertically opposite each other.

[0011] Furthermore, a pair of lower clamping blades are provided, and there is a gap space between the pair of lower clamping blades that allows the upper clamping blade to be inserted. The cutting edges of both the lower and upper clamping blades are V-shaped, and both the lower and upper clamping blades are provided with multiple locking teeth.

[0012] And / or, the bottom of the lifting screw is rotatably provided with a knife holder, the clamp frame is provided with a vertical limiting strip, the knife holder is slidably connected to the limiting strip, and the upper clamping knife is detachably connected to the knife holder by bolts.

[0013] Furthermore, each of the adjustment components includes a support, a rod, and a driving component. The support is disposed on the bracket, the rod passes through the support, the base of the fixing clamp is disposed on the top of the rod, and the driving component is used to drive the rod to move up and down and fix its position after movement.

[0014] Furthermore, the rod body is a stud, the driving component includes a worm gear, a worm, and a handwheel. The worm gear is rotatably disposed within the support and is threadedly engaged with the stud. The worm is rotatably disposed within the support and meshes with the worm gear. The handwheel is fixedly disposed on the worm and is used to drive the worm to rotate.

[0015] And / or, the top of the lifting screw is provided with a rotating handle.

[0016] Furthermore, a fixed seat is provided on the rod of the adjustment assembly on which the infrared emitter is installed, and a connecting structure is provided on the fixed seat. The infrared emitter is disposed on the connecting structure, and the connecting structure can adjust the rotation angle of the infrared emitter and fix it to the rotated position.

[0017] Furthermore, the connecting structure includes a pair of clamping plates, with support rods clamped at both ends of the clamping plates. Rotating rods are fixed on the two support rods, which pass through the pair of clamping plates and are threadedly connected at both ends by nuts to abut against the clamping plates. The ends of the two support rods away from the clamping plates are respectively fixedly connected to the infrared emitter and the fixed base.

[0018] Furthermore, the bracket is provided with a guide rail along its length, the support is fixedly mounted on the base plate, and both the base plate and the base are provided with sliders, which are slidably engaged with the guide rails.

[0019] Furthermore, a pull hook is hinged to one side of the clamp frame, a seat lug is fixedly provided on the base, and a barb is provided on the seat lug. The hook body of the pull hook can engage with the barb.

[0020] Furthermore, the seat lugs are provided in pairs and correspond to the two ends of the clamp frame. The two ends of the clamp frame are provided with locking holes. The locking holes are vertical waist holes. Locking pins are inserted into the locking holes and are also inserted into the seat lugs. The length of the locking holes is greater than the diameter of the locking pins, so that the clamp frame has space for vertical movement.

[0021] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0022] 1. This utility model, by setting a fixing clamp on the bracket, can reliably position the horizontal pipe during the ground assembly stage. Combined with an infrared emitter to form a vertical optical path, it allows construction personnel to visually determine the direction of the tee. When the casting line on the outer wall of the tee coincides with the optical path, it can be confirmed that the side opening of the tee has been adjusted to a vertical position. Since tees are usually made of metal and symmetrically formed during the casting process, the naturally formed casting line on its outer wall serves as an alignment reference. Using this reference in conjunction with the vertical optical path, rapid and accurate adjustment can be achieved, avoiding deviations caused by relying on visual inspection.

[0023] 2. The alignment method achieved by this invention eliminates the need for repeated tightening or retightening of the tee during high-altitude operations to ensure directional consistency. This effectively avoids the problem of thread seal or rubber ring seal failure caused by secondary tightening, reducing the risk of leakage. Simultaneously, the adjusting component can flexibly change the height of the infrared transmitter and fixing clamp, adapting to pipelines of different specifications and installation heights, improving assembly efficiency and safety. The overall structure is simple, positioning is reliable, and it can significantly improve the accuracy and efficiency of sprinkler pipe installation. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0031] The following is for reference Figures 1-4 As shown in the illustration, and further explained with reference to a specific embodiment, this embodiment provides a quick-adjustment structure for fire sprinkler riser pipes, including a bracket 100. Multiple fixing clamps 200 (without a specific number limit) are installed on the bracket 100 along its length. The fixing clamps 200 are used to allow horizontal pipes to pass through and to fix them. By evenly distributing the multiple fixing clamps 200 along the length of the bracket 100, continuous support and restraint of the horizontal pipes can be ensured throughout their length, preventing bending or displacement due to uneven stress. Simultaneously, since the horizontal pipes are restrained on the same horizontal baseline within the fixing clamps 200, the accuracy of the 700 tee installation can be effectively improved, ensuring consistent verticality of subsequent riser pipes.

[0032] An infrared emitter 300 is mounted on one side of the bracket 100 to emit a strip of light. This strip of light forms a vertical light path and illuminates the tee 700. When the tee 700 is rotated so that the casting line 720 on its outer wall coincides with the vertical light path, the side opening 710 of the tee 700 is in a vertical position. It should be noted that the tee 700 is made of metal, and during the casting process, due to symmetrical molding, it has a center line 720. This embodiment utilizes this casting line 720 as a natural alignment reference, combined with the vertical light path of the infrared emitter 300, to quickly determine and adjust the installation angle of the tee 700, avoiding errors caused by traditional manual visual inspection. This method ensures directional consistency even in batch installations, improving the overall stability and aesthetics of the piping system.

[0033] Reference Figure 1 , Figure 3 as well as Figure 4 As shown, both the fixing clamp 200 and the infrared transmitter 300 are mounted on the adjusting assembly 400. The adjusting assembly 400 can adjust the height of the fixing clamp 200 and the infrared transmitter 300 and fix them after adjustment. This structure allows construction personnel to flexibly adjust the height according to actual working conditions to adapt to different pipe diameters and installation positions, thus making the adjusting structure more versatile and adaptable. Furthermore, the adjusting assembly 400 can reliably lock after adjustment, preventing changes in height position due to vibration or external force, thereby ensuring the consistency of the infrared light path and the horizontal pipe positioning.

[0034] Reference Figure 4 As shown, the clamping clamp 200 includes a base 210, a clamp frame 220, a lifting screw 230, an upper clamping blade 240, and a lower clamping blade 250. The clamp frame 220 is arranged in a gate shape and is mounted on the base 210. The lifting screw 230 is connected to the clamp frame 220 along a vertical thread. The upper clamping blade 240 is installed on the output end of the lifting screw 230, and the lower clamping blade 250 is fixedly installed on the base 210. The upper clamping blade 240 and the lower clamping blade 250 are arranged vertically opposite each other. This structure allows the upper clamping blade 240 to move up and down via the lifting screw 230, thereby adjusting the clamping force of the horizontal tube, ensuring uniform clamping force, and avoiding uneven force on the horizontal tube, which could lead to deflection or localized damage.

[0035] The top of the lifting screw 230 is fixed with a rotating handle 421 to facilitate the rotation of the lifting screw 230.

[0036] As an optional embodiment, the infrared transmitter 300 can be adjusted to a higher position during use, allowing it to emit a longer straight-line distance at once. Typically, each horizontal pipe is clamped onto a fixing clamp 200, and tees 700 can be installed between adjacent fixing clamps 200. A single beam of light from the infrared transmitter 300 can illuminate several tees 700, ensuring consistent reference standards. This not only improves work efficiency but also avoids the tedious operation of calibrating multiple tees 700 individually, significantly reducing construction time.

[0037] Reference Figure 1 and Figure 4 As shown, a pair of lower clamping blades 250 are provided, with a gap space between them allowing the upper clamping blade 240 to be inserted. Both the lower and upper clamping blades 250 have V-shaped cutting edges, and each blade has multiple locking teeth 245. This allows for better clamping of the horizontal tube. The V-shaped structure automatically guides the horizontal tube, centering it in place, while the locking teeth 245 enhance friction and clamping force, preventing slippage or rotation of the horizontal tube during clamping, thus improving stability and safety.

[0038] As an optional embodiment, a tool holder 231 is rotatably mounted on the bottom of the lifting screw 230, and a vertical limiting strip 221 is welded onto the clamp 220 to limit and guide the tool holder 231. The tool holder 231 is slidably connected to the limiting strip 221, and the upper clamping blade 240 is detachably connected to the tool holder 231 by bolts. This design not only allows the upper clamping blade 240 to move stably vertically, but also facilitates the individual replacement of the upper clamping blade 240 when damaged or worn, reducing maintenance costs. At the same time, the guiding effect of the limiting strip 221 ensures that the clamping blade does not swing laterally during lifting, improving the reliability of clamping.

[0039] Reference Figure 3 , Figure 4 As shown, each adjustment component 400 includes a support 410, a rod 420, and a drive component 430. The support 410 is mounted on the bracket 100, the rod 420 passes through the support 410, the base 210 of the fixing clamp 200 is located on the top of the rod 420, and the drive component 430 is used to drive the rod 420 to move up and down and fix its position after movement. In other embodiments, the drive component 430 can be driven by a cylinder, electric push rod, gear, rack, etc., and is not limited here. This alternative design allows the device to be flexibly selected according to different construction environments and energy consumption conditions, making it more adaptable.

[0040] In this embodiment, the rod body 420 is a stud, and the driving component 430 includes a worm gear (not shown in the figure), a worm 431, and a handwheel 432. The worm gear is rotatably disposed within the support 410 and is threadedly engaged with the stud. The worm 431 is rotatably disposed within the support 410 and meshes with the worm gear. The handwheel 432 is fixedly disposed on the worm 431 and is used to drive the worm 431 to rotate, thereby driving the worm gear to rotate, and thus driving the rod body 420 to move up and down. In different embodiments, a limiting groove along the length direction is formed on the stud, and a limiting block is provided on the support 410. The limiting block slides relative to the limiting groove, so that the stud will not rotate with the worm gear, thus playing a limiting role.

[0041] Reference Figure 1 , Figure 3 As shown, a mounting base 310 is installed on the rod 420 of the adjusting assembly 400 that mounts the infrared emitter 300. A connecting structure 320 is provided on the mounting base 310. The infrared emitter 300 is mounted on the connecting structure 320, which can adjust the rotation angle of the infrared emitter 300 and fix it in its rotated position. This structure ensures that the infrared emitter 300 maintains a vertical optical path at different heights and angles, keeping the reference accurate.

[0042] Furthermore, the connecting structure 320 includes a pair of clamping plates 321, with support rods 322 clamped at both ends of the clamping plates 321. Rotating rods 323 are fixed to the two support rods 322, passing through the clamping plates 321 and threadedly connected at both ends by nuts 3231 to abut against the clamping plates 321. The ends of the two support rods 322 away from the clamping plates 321 are fixedly connected to the infrared emitter 300 and the mounting base 310, respectively. Tightening the nuts 3231 clamps the pair of clamping plates 321, thereby adjusting the angle of the infrared emitter 300. Since the pair of clamping plates 321 and the two support rods 322 have two degrees of rotational freedom, the adjustment range is larger, the adaptability is stronger, and it can meet the adjustment needs of the infrared light path in different installation environments.

[0043] Reference Figure 1As shown, the bracket 100 has a pair of guide rails 110 along its length. The support 410 is fixedly mounted on the base plate 411. Both the base plate 411 and the base 210 are equipped with sliders 500, which slide and engage with the guide rails 110, thereby allowing adjustment of the position of the fixing clamp 200 or the infrared transmitter 300. This cooperation between the guide rails 110 and the sliders 500 makes the layout of the entire device more flexible, allowing for flexible adjustment of component positions according to the on-site pipeline layout, thus adapting to the installation of horizontal pipes of different specifications and spacings. In other embodiments, fasteners such as bolts or clips can also be provided on the sliders 500 to fix their position, thereby allowing for more stable adjustment of the fixing clamp 200 or the infrared transmitter 300.

[0044] Reference Figure 4 As shown, a hook 600 is hinged to one side of the clamp 220, and a lug 211 is fixedly welded to the base 210. A barb 2111 is provided on the lug 211. The hook body of the hook 600 can be hooked and connected with the barb 2111. This makes it easy to pull the hook 600 to move the base 210. At the same time, rotating the hook 600 can hook onto the hook body to limit the swaying of the hook 600. The hook 600 can also be used to hang tools, increasing the multi-functionality of the structure.

[0045] A pair of lugs 211 are provided, corresponding to both ends of the clamp holder 220. Locking holes 222 are provided at both ends of the clamp holder 220. The locking holes 222 are vertical oblong holes, and locking pins 2221 pass through them, facilitating easy disassembly and installation. The locking pins 2221 also pass through the lugs 211. The length of the locking hole 222 is greater than the diameter of the locking pin 2221, but not excessively long, generally controlled between 1.2 and 1.5 times, to avoid excessive movement distance. Through this design, the clamp holder 220 can achieve a certain range of vertical movement when clamping the horizontal tube, forming a slow force application process, avoiding damage to the horizontal tube due to excessive instantaneous pressure, and ensuring the safety and reliability of the clamping process.

[0046] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
