Description

Technical Field

[0001] This utility model relates to the technical field of airtightness testing equipment, specifically to an airtightness testing device for fire protection pipelines. Background Technology

[0002] Fire protection pipelines refer to pipeline materials used in fire protection to connect fire protection equipment and materials, and to transport fire extinguishing water, gas or other media. Due to special needs, fire protection pipelines have special requirements for thickness and material, and are painted red. Fire protection pipelines need to undergo regular air tightness testing in preparation for emergencies. The air tightness testing method is to fill them with gas and perform pressure testing.

[0003] A search revealed that CN219319703U discloses a fire-fighting pipeline air tightness testing device, which includes a testing device bracket, a pipeline auxiliary handling structure installed on the front side wall of the testing device bracket, and a fire-fighting pipeline placed on the pipeline auxiliary handling structure; the testing device bracket includes a base plate and support plates welded to the four corners of the top surface of the base plate;

[0004] The aforementioned utility model uses a pipeline-assisted handling structure to raise the fire-fighting pipeline to be tested to an appropriate height, thereby facilitating the operator's testing of the airtightness of the fire-fighting pipeline. However, when testing the airtightness of the fire-fighting pipeline, multiple sets of bolts are needed to install flanges at both ends of the fire-fighting pipeline for sealing before testing can be carried out. After the test is completed, multiple sets of bolts need to be unscrewed to disassemble the flanges, making the testing process not only too cumbersome, but also inefficient when conducting batch testing.

[0005] Therefore, it is of great importance to design a fire-fighting pipeline airtightness testing device to solve the above-mentioned defects. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model designs a fire pipeline air tightness testing device. This device aims to solve the technical problems that the testing process of existing fire pipeline air tightness testing devices is not only too cumbersome, but also has low testing efficiency when conducting batch testing.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A fire-fighting pipeline air tightness testing device includes a frame, with electric linear slide rails fixedly installed at both ends of the front of the frame, electrically controlled sliders movably installed on the front of the two sets of electric linear slide rails, and testing components installed on the front of the two sets of electrically controlled sliders.

[0009] The detection assembly includes a base frame fixedly installed on the front of two sets of electrically controlled sliders. A movable frame is rotatably connected to the top of each set of base frames. A fixed hook is rotatably connected to the left side of each movable frame. A hook block is fixedly connected to the left side of the base frame at a position corresponding to the fixed hook. A receiving seat is fixedly installed at the bottom of the inner side of each set of base frames. A fire-fighting pipe is installed between the two sets of receiving seats. A positioning seat is slidably connected to the inner side of each movable frame. A first screw is threadedly connected to the top of each movable frame, and the bottom end of the first screw is rotatably connected to the top of the positioning seat. A connecting frame is fixedly installed on the opposite side of each set of positioning seats. A first sealing plate and a second sealing plate are movably installed at opposite ends of each set of connecting frames. One end of the first sealing plate and the second sealing plate are slidably connected to the connecting frame. A second screw is threadedly connected to one end of each set of connecting frames, and the two sets of second screws are rotatably connected to the first sealing plate and the second sealing plate, respectively.

[0010] As a preferred embodiment of this utility model, a mounting bracket is fixedly installed at the bottom of the base frame, and the rear end of the mounting bracket is fixedly connected to the electrically controlled slider.

[0011] As a preferred embodiment of this utility model, guide rails are fixedly connected to both the left and right sides inside the movable frame, and the left and right ends of the positioning seat are slidably connected to the guide rails. A first operating handle is fixedly connected to the top end of the first screw.

[0012] As a preferred embodiment of this utility model, a V-shaped groove is provided on the side opposite to the receiving seat and the positioning seat, and a protective rubber pad is fixedly connected to the inner side of both sets of V-shaped grooves.

[0013] As a preferred embodiment of this utility model, rubber sealing gaskets are fixedly connected to the opposite sides of the first sealing plate and the second sealing plate. An air pump is fixedly installed on the inner side of the frame. The air pump is fixedly connected to the first sealing plate through an air pipe. A detection tube is fixedly connected to the right side of the second sealing plate. A pressure gauge is fixedly connected to the right end of the detection tube. Both the air pipe and the detection tube are movably connected to the connecting frame.

[0014] As a preferred embodiment of this utility model, both the first sealing plate and the second sealing plate are slidably connected to the connecting frame via a slide rod, and the ends of the two sets of second screws that are far apart are fixedly connected to a second operating handle.

[0015] As a preferred embodiment of this utility model, casters are installed at the four corners of the bottom of the frame, and support feet are threadedly connected to the bottom of the frame and on the outside of the multiple sets of casters.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, through the design of the detection components, when conducting airtightness testing on fire-fighting pipelines, the electric control slider is first lowered to its lowest point. Then, the fixed hook is rotated to disengage from the hook block, thereby opening the movable frame to facilitate the installation of the fire-fighting pipeline onto the two sets of receiving seats. The movable frame is then closed, and the fixed hook is hooked onto the hook block. At this point, the first screw is rotated to lower the positioning seat until it is fixed to the outside of the fire-fighting pipeline. After that, the base frame is raised to facilitate the airtightness testing operation. After the fire-fighting pipeline is raised, the second screw is rotated until the first sealing plate and the second sealing plate seal both ends of the fire-fighting pipeline respectively, and then the airtightness testing operation can be performed. This allows for rapid airtightness testing of fire-fighting pipelines, thereby greatly improving the convenience of operation and testing efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1-3 This utility model provides a technical solution:

[0024] A fire-fighting pipeline air tightness testing device includes a frame 1. Electric linear slide rails 2 are fixedly installed on both the left and right ends of the front of the frame 1. Electric control sliders 3 are movably installed on the front of the two sets of electric linear slide rails 2. Testing components 4 are installed on the front of the two sets of electric control sliders 3.

[0025] First, in this embodiment, the specific structure of the detection component 4 is as follows:

[0026] The detection assembly 4 includes a base frame 401 fixedly installed on the front of two sets of electrically controlled sliders 3. A movable frame 402 is rotatably connected to the top of each set of base frames 401. A fixed hook 403 is rotatably connected to the left side of the movable frame 402. A hook block 404 is fixedly connected to the left side of the base frame 401 at a position corresponding to the fixed hook 403. A receiving seat 405 is fixedly installed at the bottom of the inner side of each set of base frames 401. A fire-fighting pipe 406 is installed between the two sets of receiving seats 405. A positioning seat 407 is slidably connected to the inner side of the movable frame 402. A first threaded connection is made to the top of the movable frame 402. The screw 408 is rotatably connected to the top of the positioning seat 407. A connecting frame 409 is fixedly installed on the opposite side of the two sets of positioning seats 407. A first sealing plate 410 and a second sealing plate 411 are movably installed on opposite ends of the two sets of connecting frames 409, respectively. One end of the first sealing plate 410 and the second sealing plate 411 is slidably connected to the connecting frame 409. A second screw 412 is threadedly connected to one end of the two sets of connecting frames 409, and the two sets of second screws 412 are rotatably connected to the first sealing plate 410 and the second sealing plate 411, respectively.

[0027] Furthermore, when performing an airtightness test on the fire-fighting pipe 406, first control the electric slider 3 to lower the base frame 401 to its lowest point, then rotate the fixed hook 403 to disengage it from the hook block 404, thereby opening the movable frame 402 to facilitate the installation of the fire-fighting pipe 406 onto the two sets of receiving seats 405. Then close the movable frame 402 and hook the fixed hook 403 onto the hook block 404. At this time, rotate the first screw 408 to lower the positioning seat 407 until the positioning seat 407 fixes the outside of the fire-fighting pipe 406. Then raise the base frame 401 to facilitate the airtightness test operation. After raising the fire-fighting pipe 406, rotate the second screw 412 until the first sealing plate 410 and the second sealing plate 411 seal both ends of the fire-fighting pipe 406 respectively, and then the airtightness test operation can be performed. This allows for a quick airtightness test of the fire-fighting pipe 406, thereby greatly improving the convenience of operation and the efficiency of testing.

[0028] Furthermore, a mounting bracket 413 is fixedly installed at the bottom of the base frame 401. The rear end of the mounting bracket 413 is fixedly connected to the electronically controlled slider 3. The mounting bracket 413 facilitates the assembly of the detection component 4 onto the front of the electronically controlled slider 3.

[0029] Then, guide rails 414 are fixedly connected to both the left and right sides inside the movable frame 402. The left and right ends of the positioning seat 407 are slidably connected to the guide rails 414. The top end of the first screw 408 is fixedly connected to the first operating handle 415. When the positioning seat 407 is used to fix the outside of the fire pipe 406, the first screw 408 is rotated by the first operating handle 415, thereby lowering the positioning seat 407. The positioning seat 407 descends stably with the cooperation of the guide rails 414.

[0030] Furthermore, V-grooves 416 are provided on the opposite side of the receiving seat 405 and the positioning seat 407. Protective rubber pads 417 are fixedly connected to the inner side of both sets of V-grooves 416. After the movable frame 402 is closed and fixed, the fire pipe 406 is fixed by the V-grooves 416 on the inner side of the receiving seat 405 and the positioning seat 407. The V-grooves 416 can be used for multiple specifications of fire pipes 406, thereby improving the versatility of the equipment. At the same time, the protective rubber pads 417 on the inner side can protect the outer side of the fire pipe 406 from damage.

[0031] In this system, rubber sealing gaskets 418 are fixedly connected to the opposite sides of the first sealing plate 410 and the second sealing plate 411. An air pump 419 is fixedly installed on the inner side of the frame 1. The air pump 419 is fixedly connected to the first sealing plate 410 through an air pipe 420. A detection pipe 421 is fixedly connected to the right side of the second sealing plate 411. A pressure gauge 422 is fixedly connected to the right end of the detection pipe 421. Both the air pipe 420 and the detection pipe 421 are movably connected to the connecting frame 409. The rubber sealing gaskets 418 on the inner sides of the first sealing plate 410 and the second sealing plate 411 are used to seal both ends of the fire-fighting pipe 406. Then, high-pressure gas is pumped in by the air pump 419. The air pressure value of the pressure gauge 422 is then used to determine the air tightness of the fire-fighting pipe 406.

[0032] Secondly, both the first sealing plate 410 and the second sealing plate 411 are slidably connected to the connecting frame 409 via the slide rod 423. The two sets of second screws 412 are fixedly connected to the opposite ends of each other with a second operating handle 424. When the first sealing plate 410 and the second sealing plate 411 are operated to seal both ends of the fire pipe 406, the second screws 412 are rotated by the second operating handle 424 to move the first sealing plate 410 and the second sealing plate 411. At the same time, they can move stably under the connection of the slide rod 423.

[0033] Finally, casters 101 are installed at the four corners of the bottom of the frame 1. Support feet 102 are threadedly connected to the bottom of the frame 1 and the outside of the multiple casters 101. The frame 1 can move the entire equipment easily by means of the casters 101 at the bottom. During the inspection process, the support feet 102 are rotated to make them touch the ground for fixation.

[0034] In this embodiment, the specific implementation scenario is as follows: When performing an airtightness test on the fire-fighting pipeline 406, firstly, control the electronically controlled slider 3 to lower the base frame 401 to its lowest point. Then, rotate the fixing hook 403 to disengage it from the hook block 404, thereby opening the movable frame 402 to facilitate the installation of the fire-fighting pipeline 406 onto the two sets of receiving seats 405. Then, close the movable frame 402 and hook the fixing hook 403 onto the hook block 404. At this time, rotate the first screw 408 to lower the positioning seat 407 until the positioning seat 407 fixes the outside of the fire-fighting pipeline 406. After that, raise the base frame 401 to facilitate the airtightness test operation. After raising the fire-fighting pipeline 406, rotate the second screw 412 until the first sealing plate 41... After the first sealing plate 410 and the second sealing plate 411 seal both ends of the fire-fighting pipe 406, the air tightness test can be performed. This allows for a quick air tightness test of the fire-fighting pipe 406. The two ends of the fire-fighting pipe 406 are sealed using the rubber sealing gaskets 418 on the inner side of the first sealing plate 410 and the second sealing plate 411. Then, high-pressure gas is pumped in by the air pump 419, and the air pressure value is measured by the pressure gauge 422 to determine the air tightness of the fire-fighting pipe 406. The entire operation process is simple and convenient. Compared with existing fire-fighting pipe air tightness testing equipment, this utility model can quickly perform air tightness testing on the fire-fighting pipe 406, greatly improving the convenience of operation and testing efficiency.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
