Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to an assembled construction method for a fire sprinkler full system. Background Art

[0002] With the rapid development of social economy and the acceleration of urbanization, there are more and more large buildings such as high-rise buildings, large shopping malls, factories, etc., and the risk of fire has also increased. This has led to increasing attention to fire safety issues, and fire sprinkler systems have also been widely used and developed. In the early stages, fire sprinkler systems were relatively simple, mainly using on-site welding and assembly.

[0003] As an indispensable part of the building installation field, the fire sprinkler system still has a lot of room for speeding up and increasing efficiency in the construction process. In order to speed up production progress, improve processing accuracy, improve overall construction quality, reduce dependence on on-site construction conditions and workers, and ultimately achieve factory prefabrication and on-site assembly construction of pipelines and equipment, it is very necessary to study the assembled installation of the entire automatic sprinkler fire extinguishing system.

[0004] In existing construction, prefabricated pipes need to be accurately positioned and installed on site, which requires precise measurement and construction technology. Otherwise, it will affect the overall layout and function of the system. Any deviation may cause damage to the system function, or even fail to function effectively in the event of a fire, resulting in serious consequences. Therefore, there is an urgent need for a way to make reasonable plans for the installation of pipes before construction, so as to avoid safety hazards caused by planning errors to the greatest extent. Summary of the invention

[0005] In view of this, the present invention provides a method for assembling a full fire sprinkler system, which can solve the problem of unreasonable planning of existing fire protection systems during assembly construction, resulting in potential safety hazards.

[0006] The present invention is achieved in that:

[0007] The present invention provides an assembled construction method for a fire sprinkler system, which includes the following specific steps:

[0008] S10: Establish a BIM model of the entire fire sprinkler system based on the internal structure of the building, combine logistics and on-site transportation conditions, and segment the pipelines while meeting the specifications and maintenance needs;

[0009] S20: Import the pipeline segment processing drawing parameters into the factory equipment, and use CNC machine tools and fully automatic welding equipment to prefabricate the pipeline;

[0010] S30: Carry out coding and traceability management of prefabricated components; formulate a reasonable storage and transportation plan by comprehensively considering factors such as component weight and dimensions, transportation route conditions, construction site unloading and storage conditions, and project schedule, to ensure that the production, storage and transportation progress of prefabricated components is coordinated with the on-site construction progress;

[0011] S40: According to the on-site construction schedule and prefabrication processing drawings, clarify the hoisting order of each prefabricated component and assemble them in order strictly according to the numbers of each component;

[0012] S50: Seal the connections between the various pipes, fix them according to the positions on the installation drawings and connect them to the water pipes to complete the assembled installation of the entire fire sprinkler system.

[0013] The technical effects of the assembled construction method of the fire sprinkler system provided by the present invention are as follows: This design adopts an assembled construction scheme. All pipes and brackets of this system do not need to be cut, threaded, welded, etc. on site. Through the early BIM deepening and factory prefabrication, the on-site guidance of operators to efficiently prefabricate and assemble is similar to the construction method of "building blocks", which can significantly shorten the on-site construction period. By using BIM technology for full-system modeling and a set of modern equipment in the prefabrication factory, the pipelines, equipment and their accessories are reasonably segmented and integrated for prefabrication, which can accurately control the installation accuracy of each component and each section of the system (end point positioning accuracy, equipment installation position accuracy), reduce the dependence on on-site construction conditions and the technical level of operators, and greatly improve the manufacturing accuracy of each component of the system.

[0014] Factory prefabrication can more accurately control the amount of materials used, reduce material loss caused by cutting, welding, etc. on site, and reduce material costs. Reducing dangerous operations such as high-altitude welding on site significantly reduces construction safety risks and protects the lives of workers. On-site assembly is also relatively safer, reducing the possibility of accidents. The factory production environment is more conducive to quality control, and strict quality inspections can be carried out on each prefabricated component to ensure the consistency and reliability of product quality. This makes it easier to achieve quality traceability and management compared to on-site operations. Once the design and prefabrication process is determined, subsequent projects can reuse existing designs and prefabricated components to shorten the design and production cycle and reduce costs.

[0015] On the basis of the above technical solution, the fire sprinkler system assembly construction method of the present invention can also be improved as follows:

[0016] Among them, the specific steps of clarifying the hoisting order of each prefabricated component according to the on-site construction schedule and prefabrication processing drawings, and assembling them in order strictly according to the numbers of each component include:

[0017] The first step is to tie the component to the lifting assembly and move the component in three dimensions through the lifting assembly;

[0018] The second step is to initially move the components around the location to be installed;

[0019] The third step is to use the docking device to dock and position the adjacent components. After the final position is determined, the components are slowly moved by the hoisting assembly.

[0020] The fourth step is to connect the components after the vibration is reduced.

[0021] Furthermore, the hoisting assembly includes a base plate, a diagonal brace, a support rod and a suspension assembly, wherein the base plate is a folding plate structure, which is foldable and retractable in the length direction; the top of the base plate is plugged into the diagonal brace, and the diagonal brace includes two, which are respectively installed obliquely with the top of the base plate; the diagonal brace is formed by connecting a plurality of plug-in modules; the suspension assembly is arranged inside the diagonal brace, and the suspension assembly is used to suspend the components to be hoisted; the support rods are plugged into the two sides of the diagonal brace, and the support rods are used to support the diagonal brace in the vertical direction; universal wheels are installed at the position where the bottom of the support rod contacts the ground, and the universal wheels are used to follow the movement of the hoisting assembly when it moves;

[0022] The suspension assembly includes a binding assembly and a lifting assembly. The binding assembly is an arc-shaped structure and fits the side wall of the component. The lifting assembly is arranged on both sides of the binding assembly and is used to drive the binding assembly to rise and fall by winding.

[0023] The elastic coefficients of the materials on both sides of the bundling assembly with the central axis as the dividing line are different, which is used to avoid resonance of the components during movement.

[0024] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the two symmetrically distributed diagonal braces can provide diagonal pulling forces on both sides, and the diagonal forces on both sides provide better balance and stability, making it easier to control the movement and posture of the pipeline, avoiding tilting or shaking due to imbalance, and reducing the risk of accidents. The weight of the pipeline itself will affect the lifting process, and the diagonal force can effectively utilize the lever principle, reduce the force required for lifting, and facilitate operation. The support rod can help maintain the stability of the fire-fighting pipeline in an emergency, avoid sudden movement or shaking caused by the breakage or tilting of the diagonal brace, and maintain the smooth operation of the entire system. In the case of a breakage or tilting of the diagonal brace, the support rod can provide temporary support, giving time and space for repair work, and ensuring safe repair work. The bundling assembly can effectively fix the water pipe to prevent it from swinging or moving significantly during use, ensuring the stability and safety of the water pipe. Through the bundling assembly, the water pipe can be easily driven to move upward, which can simplify the installation and maintenance process of the water pipe and reduce labor costs and time costs. By using the bundling assembly, the stable operation of the water pipe under various conditions can be ensured, and the overall reliability and safety of the system can be enhanced.

[0025] The mechanism of the reel and the pull wire can conveniently control the lifting and lowering of the strapping assembly. It is simple to operate and easy to realize automation or mechanization, which improves work efficiency. Different elastic coefficients can adjust the tension of the pull wire so that the strapping assembly can maintain balance during the lifting process and avoid instability caused by excessive weight on one side.

[0026] Furthermore, the lifting assembly includes a first fixed pulley, a slide rail, a slider, a second fixed pulley, a winding wheel and a traction rope, the first fixed pulley is installed on the top of the base plate and on both sides of the diagonal brace, the slide rail is provided on the side of the diagonal brace close to the first fixed pulley, the slider is slidably connected to the slide rail, and the second fixed pulley is fixedly provided on the top of the diagonal brace; the winding wheel is provided on the top of the base plate and located on the center line of the diagonal brace; one end of the traction rope is connected to the bundling assembly, and the other end passes around the first fixed pulley, the through hole on the support rod, and the traction rope is wound around the winding wheel; one end of the winding wheel is connected to the output shaft of the motor, and the motor is used to drive the winding wheel to rotate;

[0027] The traction ropes connected at both ends of the tying assembly are made of materials with different elastic coefficients.

[0028] The beneficial effects of adopting the above-mentioned improvement scheme are: compared with complex mechanical equipment, the cost of the traction rope is lower, reducing the initial investment and maintenance costs. The maintenance and replacement of the traction rope are very simple, and only the worn parts need to be checked and replaced regularly, which reduces the difficulty of maintenance.

[0029] The traction rope passes through the fixed pulley for traction. The fixed pulley can reduce the risk of entanglement and sudden breakage of the traction rope, and improve the safety of operation. By using the fixed pulley, the direct friction between the traction rope and the diagonal support can be reduced, the service life of the traction rope and the pipeline can be extended, and the maintenance cost can be reduced. The fixed pulley can absorb some vibration, so that the vibration generated by the fire protection pipeline during the lifting process is reduced, and the stability of the system is improved.

[0030] Furthermore, the output shaft of the motor is meshedly connected to the inner wall of the winding wheel via gears, and the inner wall gears at different positions of the traction rope connected to both sides of the bundling assembly are wound around the winding wheel with different numbers of teeth.

[0031] The beneficial effect of adopting the above-mentioned improvement scheme is that traction ropes with different elastic coefficients correspond to winding wheels in different positions.

[0032] Furthermore, a movable limit piece is provided at the bottom of the base plate, and the movable limit assembly includes four universal wheels and a limit assembly arranged in the middle of the four universal wheels, and the limit assembly includes a positioning shaft, a positioning cylinder, a limit spring, a limit column, a mounting block, a fixed support plate, a fixed sheet and a hydraulic cylinder, and the positioning shaft is welded and fixedly arranged at the center position of the bottom of the base plate, and the positioning cylinder is slidably arranged on the outside of the positioning shaft, and the limit spring is arranged inside the positioning shaft, and the upper end of the limit spring abuts against the lower end surface of the base plate, and the lower end of the limit spring abuts against the top of the positioning cylinder; in the lower end surface of the base plate Two limit columns are symmetrically installed on both sides of the part, and a limit hole is provided at the middle and lower end of each limit column, and the limit hole is square; two limit blocks are symmetrically welded on the two side walls of the positioning cylinder, and the limit blocks are respectively located inside the two limit holes; the lower end of the positioning cylinder is welded to the mounting block, and the mounting block is square; each side of the mounting block is welded with the fixed support plate, and the fixed support plate is L-shaped, and the fixing plate is welded and fixed to the end of each fixed support plate; one end of the hydraulic cylinder is fixedly connected to the fixed support plate, and the other end of the hydraulic cylinder is fixedly connected to the bottom of the base plate.

[0033] The beneficial effects of adopting the above-mentioned improved solution are as follows: the movable limiter can effectively prevent the device from moving randomly during operation, ensure that the device remains in the preset position, and improve the stability and reliability of the system. By limiting the movement range of the device, the movable limiter can improve the accuracy of the operation, especially in situations where precise position adjustment is required, such as the docking direction adjustment of a fire hose.

[0034] Furthermore, the docking device includes an active connector, a passive connector, a sealing ring, a positioning pin, a locking mechanism and a sensor module. The active connector and the passive connector are connected by plug-in connection. The active connector is a male end and has a plurality of positioning pins for aligning with the positioning holes on the passive connector; the passive connector is a female end and cooperates with the active connector to complete the plug-in connection; the sealing ring is located between the active connector and the passive connector, and the locking mechanism is used to lock the active connector and the passive connector after the connection is completed; the sensor module is arranged at the corresponding positions of the active connector and the passive connector, and is used to monitor the positional relationship between the active connector and the passive connector;

[0035] The positioning pin adopts a tapered structure to enable the active connector and the passive connector to be aligned and inserted.

[0036] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the docking device can significantly simplify the installation process of the fire hose, reduce the complicated connection work, and improve the installation efficiency. The high-quality docking device can ensure the tight and leak-free connection between the fire hoses, and improve the overall reliability of the system. The use of the docking device can reduce the time and cost of manual operation, improve construction efficiency, and reduce the overall project cost.

[0037] High-quality docking devices can ensure the sealing and fixation of water pipe connections, reduce the risk of leakage and loose connections, and improve the safety of the system.

[0038] Furthermore, the sealing ring adopts a multi-layer composite structure, including an inner layer, a middle layer and an outer layer. The inner layer adopts a soft elastic material to improve the sealing performance; the middle layer adopts a reinforcing material to improve the strength and pressure resistance of the sealing ring; the outer layer adopts a corrosion-resistant and wear-resistant material to extend the service life of the sealing ring.

[0039] Furthermore, the active connector and the passive connector are respectively provided with guide grooves for guiding the active connector and the passive connector to align during the connection process, and the shape and size of the guide grooves match the positioning pins and positioning holes, so as to improve the efficiency and success rate of the connection.

[0040] Furthermore, the sensor module is an infrared ranging sensor.

[0041] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the infrared distance sensor can automatically detect the distance between fire hoses, ensure the precise alignment of the joints, and reduce the errors of manual operation. Through automated detection, the time for manual inspection and adjustment can be reduced, the installation efficiency of fire hoses can be improved, and time and cost can be saved. The infrared distance sensor can be integrated with the remote monitoring system to realize real-time monitoring and management of the connection status, which is convenient for inspection and maintenance at different locations.

[0042] Compared with the prior art, the beneficial effects of the assembled construction method of the fire sprinkler system provided by the present invention are as follows: the present design adopts an assembled construction scheme, and all the pipes and brackets of the system do not need to be cut, threaded, welded, etc. on site. Through the early BIM deepening and factory prefabrication, the on-site guidance of the operators to efficiently carry out prefabrication and assembly is similar to the construction method of "building blocks", which can significantly shorten the on-site construction period. By using BIM technology for full system modeling and a set of modern equipment in the prefabrication factory, the pipelines, equipment and their accessories are reasonably segmented and integrated for prefabrication, which can accurately control the installation accuracy of each component and each section of the system (end point positioning accuracy, equipment installation position accuracy), reduce the dependence on on-site construction conditions and the technical level of the operators, and greatly improve the manufacturing accuracy of each component of the system.

[0043] Factory prefabrication can more accurately control the amount of materials used, reduce material loss caused by cutting, welding, etc. on site, and reduce material costs. Reducing dangerous operations such as high-altitude welding on site significantly reduces construction safety risks and protects the lives of workers. On-site assembly is also relatively safer, reducing the possibility of accidents. The factory production environment is more conducive to quality control, and strict quality inspections can be carried out on each prefabricated component to ensure the consistency and reliability of product quality. This makes it easier to achieve quality traceability and management compared to on-site operations. Once the design and prefabrication process is determined, subsequent projects can reuse existing designs and prefabricated components to shorten the design and production cycle and reduce costs.

[0064] Furthermore, in the above technical solution, the output shaft of the motor is connected to the inner wall of the winding wheel 1425 through gear meshing, and the traction rope 1426 connected on both sides of the bundling assembly 141 is wound around the inner wall gears at different positions of the winding wheel 1425 with different numbers of teeth.

[0065] Further, in the above technical solution, a movable limiting component is arranged at the bottom of the base plate 11, and the movable limiting component includes four universal wheels and a limiting component arranged in the middle of the four universal wheels, and the limiting component includes a positioning shaft 111, a positioning cylinder 112, a limiting spring 113, a limiting column 114, a mounting block 115, a fixed support plate 116, a fixing plate 117 and a hydraulic cylinder 118.

[0066] Further, in the above technical solution, the docking device includes an active connector 21, a passive connector 22, a sealing ring 23, a positioning pin 24, a locking mechanism 25 and a sensor module 26. The active connector 21 and the passive connector 22 are connected by plug-in connection. The active connector 21 is a male end and has a plurality of positioning pins 24 for aligning with the positioning holes on the passive connector 22; the passive connector 22 is a female end and cooperates with the active connector 21 to complete the plug-in connection; the sealing ring 23 is located between the active connector 21 and the passive connector 22, and the locking mechanism 25 is used to lock the active connector 21 and the passive connector 22 after the connection is completed; the sensor module 26 is arranged at the corresponding positions of the active connector 21 and the passive connector 22, and is used to monitor the positional relationship between the active connector 21 and the passive connector 22;

[0067] The positioning pin 24 has a tapered structure, so as to enable the active connector 21 and the passive connector 22 to be aligned and inserted.

[0068] The locking mechanism includes a fixed shaft, a rotating block and an extruder; the fixed shaft is fixedly connected to the fire pipe, the fixed shaft passes through the rotating block and is rotationally connected to the rotating block, and the extruder is fixedly connected to the rotating block. A reset spring is provided at the connection between the fixed shaft and the rotating block. The extruder is adapted to the active connector 21 and the passive connector 22.

[0069] Furthermore, in the above technical solution, the sealing ring 23 adopts a multi-layer composite structure, including an inner layer, a middle layer and an outer layer. The inner layer adopts a soft elastic material to improve the sealing performance; the middle layer adopts a reinforced material to improve the strength and pressure resistance of the sealing ring; the outer layer adopts a corrosion-resistant and wear-resistant material to extend the service life of the sealing ring.

[0070] Furthermore, in the above technical solution, the active connector 21 and the passive connector 22 are respectively provided with guide grooves for guiding the active connector 21 and the passive connector 22 to align during the connection process.

[0072] Furthermore, in the above technical solution, the sensor module 26 is an infrared ranging sensor.

[0073] When in use, the fire pipe is placed on the bundling assembly 141, and the pushing device is moved. At this time, the universal wheel under the bottom plate 11 and the universal wheel under the support rod 13 are grounded and moved together. When they move to the predetermined position, the movable limiter is started to limit the position of the lifting assembly. First, the hydraulic cylinder 118 is started to drive the fixed support plate 116 to move downward, and the fixed plate 117 contacts the ground until the movable limiter lifts the bottom plate. At this time, the universal wheel leaves the ground to limit the lifting assembly. Put the fire pipe on the bundling assembly 141, start the motor to drive the winding wheel 1425 to rotate. Since the traction and winding directions of the traction ropes 1426 on both sides are opposite, and the upper and lower parts of the winding wheel 1425 can rotate separately, when the motor drives the winding wheel 1425 to rotate, the pay-off speeds of the traction ropes 1426 on both sides are different. Since the elastic coefficients of the traction ropes 1426 on both sides are different, the balance of the pulling force on both sides can be achieved by paying off the speed and changing the traction ropes 1426 of different materials.

[0074] When multiple fire-fighting pipes are pulled to a predetermined height for connection, the active connector 21 and the passive connector 22 are aligned, and the positioning pins 24 are inserted into the corresponding positioning holes. The extruder is bent to drive the rotating block to rotate on the fixed axis. The extruder bypasses the special-shaped protrusions on the active connector 21 and the passive connector 22 to squeeze the active connector 21 and the passive connector 22 and is stuck between the protrusions.

[0075] Embodiment 1:

[0076] Before construction, the collection of information such as engineering drawings, standard specifications, pipeline and equipment selection samples (samples), prefabrication plant production capacity, road traffic conditions, machinery and equipment, and prefabricated industrial workers should be completed, preliminary preparations should be made, and the site layout should be reasonably planned so as to maximize the advantages of prefabricated construction.

[0077] Use REVIT software to build the corresponding BIM model for electromechanical pipelines, and use the visualization function of software such as Navisworks to conduct virtual roaming, collision checks, and clear height analysis to accurately determine the location of each professional pipeline for electromechanical installation, and form a full-professional BIM model that can guide construction. The BIM drawings of the automatic fire sprinkler system are exported for further optimization, and standardized modular design is carried out. The pipelines are reasonably segmented and coded to export the processing drawings of each pipe section and generate a parameter information library for each pipe section and accessories.

[0078] The fire pump room building structure was re-measured using a total station robot. The measurement contents mainly included the equipment room building elevation, structural inclination, and the position and elevation of the flange of the pipe after the equipment was in place. After the measurement, the measured data was fed back to the equipment room BIM model, and the model was adjusted or the existing structural components were appropriately corrected as needed.

[0079] Optimize the layout of each device and pipeline in the machine room to make it reasonable and beautiful. Scientifically segment and encode the pipeline and equipment models into digital modules. The fire pump adopts modular design, that is, each pump unit module is an independent unit, and each unit module includes a pump, valve, pipeline and other accessories.

[0080] The processing drawings and assembly drawings of the modules such as the supports, pipes, and pump rooms formed in the detailed design stage are compiled into a book and delivered to the prefabrication factory. The pipeline prefabrication processing drawings are an effective guide for the prefabrication of all pipes in the automatic fire sprinkler system, and are also the basis for the modular assembly of each pipe section. Therefore, all parameter information must be accurate and complete.

[0081] The prefabrication drawing of the fire pump group includes information such as the material type, processing size, precision requirements and processing precautions of each component, which is the basis for modular assembly of the pump room. At the same time, the dimensions of special equipment components such as valves and water pumps should be communicated and checked with the manufacturer in advance to ensure the smooth implementation of prefabrication, transportation and installation.

[0082] For centralized prefabrication in the factory, the relationship between the on-site assembly schedule, the time consumption of component transportation, and the factory prefabrication cycle should be coordinated in advance to ensure that the production, transportation, and installation are connected in an orderly, compact and reasonable manner, shorten the time difference as much as possible, and improve construction efficiency. The prefabrication factory conducts centralized prefabrication of the various components of the automatic sprinkler system based on the prefabrication processing drawings and parameter information database formed in the in-depth design stage. The processing should adopt a digital fully automatic production line. The processing process mainly includes cutting and blanking, pipe threading (grooving), pipe connection, anti-corrosion spray painting (touch-up), flushing and pressure testing, coding and identification, and finished product protection. The prefabrication principles and requirements for each module are as follows:

[0083] 1. Prefabrication of sprinkler pipe modules

[0084] According to the fire protection pipeline prefabrication processing drawing, high-precision CNC automation equipment is used to process the pipeline module. The sprinkler main pipe is connected by clamps, and the sprinkler branch pipe is connected by threaded connections. After the pipeline module is prefabricated, it is flushed according to the specifications and coded according to the assembly sequence.

[0085] 2. Prefabrication of fire pump module

[0086] According to the prefabrication drawing of the fire pump group, the water pump (fire pump, sprinkler pump), valve (signal valve, alarm valve, etc.), instrument, pressure stabilizing device, etc. are modularly prefabricated, and the processing accuracy is strictly controlled to minimize the relative error with the foundation. At the same time, reliable finished product protection and temporary reinforcement measures during transportation should be taken.

[0087] 3. The project submits a material demand plan for each material based on the progress on site. The prefabricated manufacturer encodes various specifications and models of materials, and then uses logistics tracking and QR code technology to trace the prefabricated material information. Specifically, the PC and mobile terminals can be used to achieve two-way traceability management of information on the production, transportation, assembly and other links of the module, thereby improving the traceability and management efficiency of building information.

[0088] 4. Install the main pipe section according to the detailed drawings and section drawings. During installation, pay attention to controlling the rotation angle of the main pipe section to ensure the correctness of the connection between the branch pipe and the main pipe.

[0089] 5. Before assembling the fire pump module, a virtual three-dimensional lifting operation environment should be established based on the site conditions and the pipe segment and equipment lifting plan, and the horizontal transportation and lifting process simulation of the prefabricated pipe segment and equipment should be carried out. The pipe segment and equipment lifting process should be simulated in the form of three-dimensional animation to verify the feasibility of the lifting plan. Then, according to the detailed drawings, the foundation size, position, anchor bolt position and equipment parameters should be reviewed again to see if they are consistent with the design to avoid rework due to mistakes. After the verification, the pump group and other equipment modules should be in place first, and then the main pipeline should be assembled, and finally the vertical pipe segment should be installed. The vertical pipe segment should be set with a compensation section to control the deviation. For larger pipe segments, they can be lifted with the help of lifting components.

[0090] Among them, in the above technical scheme, according to the on-site construction schedule and prefabrication processing drawings, the hoisting order of each prefabricated component is clarified, and the specific steps of assembling in order strictly according to the number of each component include:

[0091] The first step is to tie the component to the lifting assembly and move the component in three dimensions through the lifting assembly;

[0092] The second step is to initially move the components around the location to be installed;

[0093] The third step is to use the docking device to dock and position the adjacent components. After the final position is determined, the components are slowly moved by the hoisting assembly.

[0094] The fourth step is to connect the components after the vibration is reduced.

[0095] Specifically, the principle of the present invention is: place the fire pipe on the bundling assembly 141, and push the device to move. At this time, the universal wheel under the bottom plate 11 and the universal wheel under the support rod 13 are grounded and move together. When they move to the predetermined position, the movable limiter is started to limit the position of the lifting assembly. First, the hydraulic cylinder 118 is started to drive the fixed support plate 116 to move downward, and the fixed plate 117 contacts the ground until the movable limiter lifts the bottom plate. At this time, the universal wheel leaves the ground to limit the lifting assembly. Put the fire pipe on the bundling assembly 141, start the motor to drive the winding wheel 1425 to rotate. Since the traction and winding directions of the traction ropes 1426 on both sides are opposite, and the upper and lower parts of the winding wheel 1425 can rotate separately, when the motor drives the winding wheel 1425 to rotate, the release speed of the traction ropes 1426 on both sides is different. Since the elastic coefficients of the traction ropes 1426 on both sides are different, the balance of the pulling force on both sides can be achieved by releasing the speed and changing the traction ropes 1426 of different materials.

[0096] When multiple fire-fighting pipes are pulled to a predetermined height for connection, the active connector 21 and the passive connector 22 are aligned, and the positioning pins 24 are inserted into the corresponding positioning holes. The extruder is bent to drive the rotating block to rotate on the fixed axis. The extruder bypasses the special-shaped protrusions on the active connector 21 and the passive connector 22 to squeeze the active connector 21 and the passive connector 22 and is stuck between the protrusions.

[0097] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
