Description

Technical Field

[0001] This utility model relates to the field of fire protection testing technology, specifically a fire protection pipeline air tightness testing device. Background Technology

[0002] Air tightness testing is a crucial step in ensuring the effectiveness and safety of fire protection facilities, especially in environments requiring high pressure or containing toxic gases. Air tightness directly impacts the reliability of fire protection systems in emergency situations. For example, Chinese patent application CN202422818966.8 discloses a fire protection air tightness testing device. This device utilizes a motor, threaded rod, and slider to facilitate the left-right movement of the mounting base and sealing sleeve, enabling rapid sealing of both ends of fire protection pipes. It is easy to operate. The sealing sleeve incorporates a sealing groove and a conical sealing plug, effectively improving the sealing of the connections at both ends of the fire protection pipes, preventing gas leaks, and enhancing the accuracy of air tightness testing. However, because fire-fighting pipelines need to withstand high air and water pressure, their walls are thick and made of special materials, mostly alloys, resulting in a large weight. When inspecting these pipelines, operators need to move or hoist them onto the testing platform to facilitate the testing work. This process is cumbersome, time-consuming, labor-intensive, inflexible, and inefficient. Therefore, this case was developed to address these issues in depth. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Refer to the appendix of the instruction manual Figure 1-5As can be seen, this application specifically designs a fire-fighting pipeline airtightness testing device, including a main body 1 of the fire-fighting pipeline airtightness testing device and a portal truss 2 set above the testing platform of the main body 1. A movable bracket 3 for placing fire-fighting pipelines is provided on one side of the main body 1. A horizontal moving mechanism is provided on the portal truss 2. A vertical adjustment mechanism is provided at the moving end of the horizontal moving mechanism. A pipeline clamping mechanism is provided at the lower end of the vertical adjustment mechanism. The pipeline clamping mechanism includes a fixed base 4 set at the lower end of the vertical adjustment mechanism. A pipe clamping mechanism is provided at the lower end of the fixed base 4. Mounting plate 5, on which an electric telescopic rod 6 is installed. Two L-shaped grippers 7 are symmetrically arranged on both sides of the electric telescopic rod 6. The middle part of the L-shaped grippers 7 is rotatably connected to the mounting plate 5, and the upper part is hinged to the movable end of the electric telescopic rod 6 through a connecting seat 8. The lower end of the L-shaped grippers 7 is provided with an arc-shaped clamping block 9, and the inner side of the arc-shaped clamping block 9 is provided with a rubber anti-slip pad 10. Based on the existing fire air tightness testing equipment body 1, a horizontal truss is added above the fire air tightness testing equipment body 1. The horizontal truss integrates and installs a horizontal moving mechanism, a vertical adjustment mechanism, and a pipe clamping mechanism. Through the coordinated operation of three sets of mechanisms, the fire-fighting pipeline is placed onto the support sleeve on the main body 1 of the fire-fighting airtightness testing equipment, and the main body 1 of the fire-fighting airtightness testing equipment performs airtightness testing on the pipeline. This equipment can automatically grab, move, and place the fire-fighting pipeline to be tested. After the main body 1 of the fire-fighting airtightness testing equipment completes the airtightness testing of the fire-fighting pipeline, the fire-fighting pipeline is moved out of its current position. The structure is compact and highly automated, which can greatly reduce the difficulty of operation for operators. The double-sided feeding method can significantly improve the efficiency of the testing operation. During use, the electric telescopic rod 6 is controlled. The movable end expands, which in turn pushes the connecting seat 8 downward. During the downward movement of the connecting seat 8, it pulls the ends of the L-shaped grippers 7 on both sides to move, thereby causing the L-shaped grippers 7 to open. When the L-shaped grippers 7 move to both sides of the fire pipe, the movable end of the electric telescopic rod 6 is retracted, thereby controlling the L-shaped grippers 7 to lock together and clamp and fix the fire pipe. It should be noted that the main body 1 of the fire air tightness testing equipment can refer to the existing fire air tightness testing equipment disclosed in the background art. Its specific operation process and working principle are known technologies and will not be described in detail here.

[0019] In the specific implementation process, the above-mentioned horizontal moving mechanism includes a fixed groove 11 set on a horizontal truss, a transmission screw 12 rotatably set in the fixed groove 11, a servo drive assembly connected to the exposed end of the transmission screw 12, sliding limit assemblies symmetrically arranged on both sides of the transmission screw 12, a screw nut screwed on the transmission screw 12, and a moving seat 13 fixedly nested outside the screw nut. The moving seat 13 is connected to a slider on both sides, and the slider slides in cooperation with the slide rail. The servo drive assembly includes a servo motor 14, a reducer 15, and a coupling 16. The input end of the reducer 15 is connected to the drive end of the servo motor 14. One end of the coupling 16 is connected to the transmission screw 12, and the other end is connected to the output end of the reducer 15. In use, through the cooperation of the servo motor 14 and the reducer 15, the coupling 16 is used to control the rotation of the transmission screw 12. During the rotation of the transmission screw 12, the moving seat 13 is driven to slide horizontally along the slide rail, thereby realizing the adjustment and control of the horizontal position of the fire pipeline.

[0020] In the specific implementation process, the above-mentioned vertical adjustment mechanism includes two sets of hydraulic cylinders 17 symmetrically arranged at the lower end of the movable seat 13. The movable end of the hydraulic cylinder 17 is connected to the fixed seat 4. Telescopic columns 18 are symmetrically arranged on both sides of the hydraulic cylinder 17. The two ends of the telescopic columns 18 are connected to the movable seat 13 and the fixed seat 4 respectively. The hydraulic cylinder 17 is used as the power source to realize the vertical position adjustment of the fixed seat 4, and then, with the cooperation of the telescopic columns 18, the height of the fire-fighting pipeline is adjusted.

[0021] In the specific implementation process, an infrared signal receiver 19 is provided at the lower end of the aforementioned movable seat 13, and an infrared signal transmitter 20 is provided on the detection platform at the position corresponding to the infrared signal receiver 19. Infrared light is generated through the infrared signal generator. When the movable seat 13 moves to the top of the detection platform, the infrared signal receiver 19 receives the corresponding signal, which indicates that the centering is completed. The three sets of action mechanisms are controlled to act synchronously to place the fire pipe onto the support sleeve.

[0022] In the specific implementation process, the support sleeve on the above-mentioned testing platform is equipped with a pressure sensor, which can detect whether the fire-fighting pipeline is placed in place, ensuring the continuity of the testing operation.
