Description

Technical Field

[0001] This invention relates to the field of fire protection equipment maintenance technology, specifically a rapid maintenance device for fire exhaust ducts. Background Technology

[0002] Fire exhaust ducts are the core component of a building's fire exhaust system. They are made of fire-resistant materials (such as galvanized steel plates, stainless steel plates, fire-resistant fiberglass, etc.). Their function is to quickly exhaust toxic and high-temperature smoke generated in the building during a fire, while simultaneously supplementing fresh air with ventilation fans, ensuring visibility and oxygen content in evacuation routes, and creating a safe environment for people to escape and for firefighters to carry out firefighting operations.

[0003] When inspecting and maintaining inclined fire exhaust ducts, the traditional method to achieve stable support for the ducts is to use a rotatable support plate to support the ducts, and then manually tighten the plate angle with bolts. Although this method can meet the basic support requirements, the operator needs to use external equipment to climb to the corresponding height of the duct and manually adjust the plate angle to match the duct inclination. In the process, the position needs to be repeatedly calibrated before the bolts can be tightened. Moreover, if there are multiple ducts with different inclination angles, the bolts need to be loosened, the angle adjusted, and the bolts tightened for each duct. This not only results in high labor intensity but also seriously slows down the overall maintenance progress and reduces work efficiency.

[0004] Therefore, it is necessary to provide a rapid inspection and maintenance device for fire exhaust ducts to solve the above-mentioned technical problems. Summary of the Invention

[0013] As a further aspect of the present invention: two sets of horizontal bars are symmetrically arranged along the center of the pallet, and each set of horizontal bars has a corresponding transmission component at its bottom, and both are in cooperation with the limiting component through the transmission component; when one set of horizontal bars moves down, it can drive the limiting component to disengage from the fixed plate, so that the pallet can rotate around the pivot; when the other set of horizontal bars moves down, it can drive the limiting component to limit the rotated pallet.

The transmission component causes the limiting component and the adjusting component to separate, allowing the pallet to rotate relative to the driving component until the pallet rotates to an angle suitable for the pipe, thus automatically adjusting the angle of the pallet. This facilitates subsequent maintenance work. The two sets of symmetrically arranged horizontal bars can trigger the limiting component sequentially. One set of horizontal bars drives the pallet to unlock and rotate, while the other set of horizontal bars drives the limiting component to reposition, achieving automatic switching between pallet rotation and fixation. This prevents pallet displacement during maintenance and ensures the stability of the pipeline during maintenance. Attached Figure Description

[0028] Please see Figures 1-10 In this embodiment of the invention, the rapid inspection device for fire exhaust ducts includes a base 1 and a support plate 3, and a drive component 2 disposed between the base 1 and the support plate 3. The base 1 is used for the movement and support of the device, and a drive unit is provided at one end of the top of the base 1. The drive unit can drive the wheels at the bottom of the base 1 to rotate and drive the drive component 2 to rise and fall. The height of the support plate 3 relative to the base 1 can be adjusted by raising and lowering the drive component 2, thereby facilitating the inspection of the fire exhaust duct (hereinafter referred to as "duct"). The drive component 2 is fixedly disposed at the top center of the base 1 by a bracket. A connector 6 is provided at the bottom center of the support plate 3. The support plate 3 is installed on the base 1 through the connector 6 and the drive component 2. The drive component 2 can adopt an electric push rod or a hydraulic rod, etc.

[0029] Therefore, the top of the driving component 2 is provided with an adjustment component, the connecting component 6 is rotatably engaged with the adjustment component, the end of the support plate 3 is slidably provided with a crossbar 5, the bottom of the crossbar 5 is provided with a transmission component, and the inner sidewall of the connecting component 6 is slidably embedded with a limiting component. When the crossbar 5 moves downward, the crossbar 5 drives the limiting component to move relative to the adjustment component through the transmission component. When the limiting component separates from the adjustment component, the support plate 3 can rotate around the adjustment component as an axis, thereby enabling the support plate 3 to rotate relative to the inclined pipe during maintenance work. In this embodiment, the top of the crossbar 5 is set as a semi-circular structure, and the crossbar 5 is located at the end edge of the support plate 3. Thus, in the initial state, the crossbar 5 protrudes from the top of the support plate 3, and because it is close to the end edge of the support plate 3, when raised to engage with the pipe, the top of the crossbar 5 will engage with the pipe first and be pushed downward by the pipe.

[0030] Please see Figures 2-5 , Figures 7-10The adjustment component includes a rotating shaft 15. The rotating shaft 15 is fixedly mounted on the top of the driving component 2, and both ends of the rotating shaft 15 are rotatably connected to the connecting component 6. A fixed plate 13 is symmetrically mounted around the periphery of the rotating shaft 15, and the fixed plate 13 is positioned between the driving component 2 and the connecting component 6. The fixed plate 13 has limit holes 16, which are arranged in a circular array along the axis of the fixed plate 13. The limit holes 16 slide in cooperation with the limit component. When inspecting an inclined pipe, the driving component 2 is activated to raise the support plate 3 relative to the pipe, allowing the crossbar 5 to fit against the pipe and be pushed downward by the pipe. When the crossbar 5 moves downward, the transmission component causes the limit component to separate from the adjustment component, allowing the support plate 3 to rotate relative to the driving component 2 until the support plate 3 rotates to an angle that matches the pipe, thus completing the support of the pipe and realizing automatic adjustment of the angle of the support plate 3, which facilitates subsequent maintenance work.

[0031] Please see Figures 1-7 The transmission assembly includes a support plate 7; the support plate 7 is symmetrically arranged along the center of the crossbar 5, the top of the support plate 7 is fixedly connected to the bottom of the support plate 3, a positioning rod 8 is provided between the support plate 7 and the crossbar 5, a spring is sleeved around the positioning rod 8, the positioning rod 8 is slidably connected to the crossbar 5, and the bottom of the positioning rod 8 is fixedly connected to the support plate 7, an I-beam 9 is slidably arranged on the support plate 7, the top of the I-beam 9 is fixedly connected to the bottom of the crossbar 5, when the crossbar 5 moves downward, the crossbar 5 pushes the I-beam 9 to move downward on the support plate 7.

[0032] Furthermore, a pull rope 11 is fixedly provided at the end of the I-beam 9 away from the horizontal bar 5. The end of the pull rope 11 away from the I-beam 9 is fixedly connected to the limiting component. A buckle 10 is fixedly provided at the bottom of the support plate 3. The buckle 10 is located near the I-beam 9, and the end of the pull rope 11 away from the I-beam 9 passes through the buckle 10. The buckle 10 can guide the pull rope 11 and ensure the transmission stability when the pull rope 11 pulls the limiting component.

[0033] In practical use, a torsion spring is provided at the rotational connection between the pallet 3 and the rotating shaft 15. This allows the pallet 3 to automatically rotate to a horizontal position when no external force is applied. Initially, the pallet 3 is horizontal, the drive component 2 is retracted, the crossbar 5 protrudes from the top of the pallet 3, the top of the I-beam 9 fits against the bottom of the pallet 3, and the limiting component matches a set of limiting holes 16 on the fixed plate 13. At this time, the pallet 3 remains horizontal and cannot rotate. When pipeline maintenance is required, the drive component 2 is activated to drive the pallet 3 upwards. When the crossbar 5 is aligned with the pipe... When the bottom of the pipe is in contact with the pipe and is pushed away from the support plate 3, the crossbar 5 pushes the I-beam 9 to move. The movement of the I-beam 9 causes the pull rope 11 to be pulled under the guidance of the buckle 10, thereby causing the limiting component to move away from the limiting hole 16 in the direction of the connector 6. This allows the support plate 3 to rotate around the pivot 15. Then, the drive component 2 continues to drive the support plate 3 to rise. At this time, one end of the support plate 3 is in contact with the pipe, so the support plate 3 will rotate until it matches the angle of the pipe's inclination, thus facilitating the maintenance of the inclined pipe.

[0034] In order for the support plate 3, which is adapted to rotate and tilt the pipe, to effectively support the pipe, preferably, please refer to... Figures 1-9 Two sets of horizontal bars 5 are symmetrically arranged along the center of the pallet 3. The horizontal bars 5 closer to the drive unit are designated as one set, and the horizontal bars 5 farther from the drive unit are designated as the other set. The bottom of each set of horizontal bars 5 is provided with a corresponding transmission component, and both sets cooperate with the limiting component through the transmission component. When one set of horizontal bars 5 moves downward, the corresponding transmission component drives the limiting component to disengage from the fixed plate 13, thereby allowing the pallet 3 to rotate around the pivot 15. When the other set of horizontal bars 5 moves downward, the transmission component drives the limiting component to limit the relative position of the pallet 3 after rotation. Through the arrangement and cooperation of the two sets of horizontal bars 5, the pallet 3 adapted to the rotating and tilting pipeline is limited, ensuring stability during pipeline maintenance.

[0035] Please see Figures 4-5 , Figures 8-9 The limiting component includes a first limiting post 17 and a second limiting post 18 with the same structure; the first limiting post 17 and the second limiting post 18 are slidably embedded in the side wall of the connector 6, and the first limiting post 17 and the second limiting post 18 are symmetrically arranged along the center of the connector 6. A spring is provided between the end of the first limiting post 17 and the second limiting post 18 away from the fixed plate 13 and the connector 6. The end of the first limiting post 17 and the second limiting post 18 away from the fixed plate 13 is fixedly connected to the end of the corresponding pull rope 11. When the I-beam 9 moves downward, under the guidance of the buckle 10, the I-beam 9 causes the first limiting post 17 or the second limiting post 18 to move relative to the fixed plate 13.

[0036] Please see Figure 2 , Figure 6 A conversion frame 19 is fixedly installed at the bottom of a set of buckles 10 near the first limiting post 17. The conversion frame 19 is located at one end of the buckle 10 near the support plate 7. A set of pull ropes 11 corresponding to the first limiting post 17 passes through the buckle 10 and around the bottom of the conversion frame 19 in sequence and is fixedly connected to the corresponding I-shaped block 9. The conversion frame 19 can change the transmission direction of the pull ropes 11 to ensure that the first limiting post 17 can be accurately moved towards the fixed plate 13 when the I-shaped block 9 moves down.

[0037] In actual use, in the initial state, both sets of horizontal bars 5 protrude from the top of the pallet 3. The first limiting post 17 is separated from the fixed plate 13, and the second limiting post 18 is adapted to the limiting hole 16 on the fixed plate 13, thereby limiting the pallet 3 in the horizontal state. When the drive unit 2 drives the pallet 3 to rise relatively to inspect the pipeline, one set of horizontal bars 5 first cooperates with the pipeline and is pushed, thereby driving the corresponding I-beam 9 to make the second limiting post 18 move away from the fixed plate 13, so that the pallet 3 can rotate relatively. When the pallet 3 rotates to the point where the other set of horizontal bars 5 cooperates with the pipeline and is pushed, the movement of the other set of horizontal bars 5 causes the corresponding I-beam 9 to move, allowing the pull rope 11 to gradually release the tension on the first limiting post 17. Under the corresponding elastic action, the first limiting post 17 moves towards the limiting hole 16 to limit the position of the rotated pallet 3, thereby ensuring that the pipeline maintains sufficient stability during the inspection process.

[0038] Please see Figure 4 , Figure 5 , Figures 8-10 A movable disk 14 is provided on the side of the fixed disk 13 near the connector 6. The movable disk 14 is slidably sleeved on the periphery of the rotating shaft 15, and the movable disk 14 and the fixed disk 13 are elastically slidably connected. A round rod that slides through the fixed disk 13 is fixedly provided on the side of the movable disk 14 near the fixed disk 13. A spring is provided between the end of the round rod away from the movable disk 14 and the fixed disk 13, so that the movable disk 14 and the fixed disk 13 remain in a close fit when the movable disk 14 is not subjected to external force. The limiting holes 16 are arranged in a circular array on the movable disk 14 along its axis and correspond one-to-one with the limiting holes 16 on the fixed disk 13.

[0039] Furthermore, a separation rod 12 is provided below the movable plate 14. The bottom of the separation rod 12 is fixedly connected to the bracket, and the top of the separation rod 12 is provided with an inclined surface facing the movable plate 14.

[0040] In actual use, in the initial state of the retracted drive component 2, the top of the separating rod 12 causes the movable plate 14 and the fixed plate 13 to separate via the inclined surface. At this time, the movable plate 14 is positioned close to the connecting component 6 and slides with the first limiting post 17 and the second limiting post 18 through the limiting hole 16, thereby limiting the relative position of the pallet 3. This prevents the pallet 3 from rotating due to accidental contact with the crossbar 5 during the movement of the device. Simultaneously, when the pipeline under maintenance is disassembled and replaced, after the drive component 2 retracts and resets, the rotated pallet 3, through the separating rod 12, extends between the fixed plate 13 and the movable plate 14, causing the movable plate 14 to contact the first limiting post 17 and the second limiting post 18. With the 8-way coordination, even after the pipe on the pallet 3 is removed, the horizontal bar 5 can still maintain the engagement between the first limiting post 17, the second limiting post 18 and the movable plate 14 after the pipe is moved and reset, keeping the pallet 3 in the limited position after rotation. Therefore, after the pipe is replaced, there is no need to manually adjust the angle of the pallet 3, which facilitates the disassembly, maintenance or replacement of the pipe. When the drive component 2 is raised, the separation rod 12 separates from the fixed plate 13 and the movable plate 14, and the movable plate 14 moves to fit against the fixed plate 13. At this time, if there is no pipe on the pallet 3, it will return to the point where only one of the first limiting post 17 and the second limiting post 18 engages with the limiting hole 16, which will trigger a set of horizontal bars 5 to move down, allowing the pallet 3 to rotate again.

[0041] Please see Figures 1-3 The pallet 3 is provided with a clamping assembly 4, which is used to clamp and fix the pipe. The clamping assembly 4 includes a cylinder 41, preferably a double-headed cylinder. The cylinder 41 is fixedly set at the bottom of the pallet 3 and is symmetrically arranged along the bottom of the pallet 3. A clamping plate 43 is fixedly set at the output end of the cylinder 41. The pallet 3 is provided with a sliding groove 42 for the clamping plate 43 to slide. In actual use, when it is necessary to clamp and fix the pipe, the cylinder 41 is activated to retract, thereby driving the clamping plate 43 to move closer to complete the clamping and fixing of the pipe on the pallet 3.
