Description

Technical Field

[0001] This invention relates to the field of fire-fighting pipeline lifting technology, specifically a foldable fire-fighting pipeline installation and lifting device. Background Technology

[0002] When installing fire protection pipes inside a building, the pipes need to be suspended to the ceiling, thus requiring lifting. Common methods for lifting fire protection pipes include: 1. Setting up scaffolding on the ground, with workers standing on the scaffolding and using ropes to pull it upwards, or workers carrying the fire protection pipes while climbing the scaffolding; 2. Using scissor lifts or similar equipment to lift the fire protection pipes.

[0003] Chinese patent CN111232867B, filed on February 7, 2020, discloses a foldable rooftop lifting device for fire-fighting pipelines. The technical problem is how to design a foldable rooftop lifting device for fire-fighting pipelines that can automatically lift fire-fighting pipelines, reducing worker labor intensity, improving fire-fighting pipeline installation efficiency, and preventing accidents. The foldable rooftop lifting device for fire-fighting pipelines includes a base, with lifting frames symmetrically fixed to one side of the top of the base. Swing frames are hinged between the ends of the lifting frames on both sides away from the base. A dual-axis motor is installed on the base side near the lifting frames. This invention uses a flipping mechanism to fold and extend the lifting frames, and the lifting mechanism lifts the fire-fighting pipelines, reducing worker labor intensity, improving fire-fighting pipeline installation efficiency, and preventing accidents.

[0004] In this technical solution, the swing frame is hinged to the top of the lifting frame. When the swing frame deflects to a vertical position, it forms a vertical structure with the lifting frame to guide the L-shaped sliding plate, allowing the L-shaped sliding plate to move up and down to lift the fire-fighting pipes. However, the fixed height of the swing frame and lifting frame assembly makes it difficult to adapt to the lifting requirements when the fire-fighting pipes are installed at different heights. For example, in cases of low floor height, the lifting frame itself has a certain height, and a large deflection radius is required during the swing frame's deflection process, which can easily make it difficult for the swing frame to deflect to a vertical position, affecting the lifting operation of the fire-fighting pipes; therefore, further improvements are needed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a foldable fire pipe installation lifting device. It features a foldable and retractable support frame that guides the lifting process of fire pipes, making it easy to adapt to the installation needs of fire pipes in buildings with different floor heights. This solves the problem that the fixed height of swing frame and lifting frame assemblies makes it difficult to adapt to the lifting needs of fire pipes installed at different heights.

[0015] Compared with the prior art, the present invention provides a foldable fire pipe installation lifting device, which has the following advantages:

[0016] 1. This foldable fire-fighting pipe installation lifting device uses a motor to drive a winding wheel to rotate, winding up a wire rope. The wire rope pulls the assembly of sliding frame two, winding wheel two, and threaded rod upwards until sliding frame two is against the top wall of sliding frame one. At this time, sliding frame one is inside the vertical plate, and sliding frame two is inside the top of sliding frame one. Then, the output end of the hydraulic cylinder extends and pushes the sliding column to the left, causing the sliding column to slide along the guide frame while pushing the vertical plate to deflect clockwise around the axis of the sleeve. This causes the assembly of the vertical plate and sliding frame one to fit against the top of trapezoidal strip two, and the assembly of sliding frame two and support plate to be located on the upper right of the right end of the traveling vehicle. This allows the support frame assembly to be folded on the top of the traveling vehicle, reducing the height of the device and facilitating passage through passages with low door heights.

[0017] 2. This foldable fire-fighting pipe installation and lifting device places the fire-fighting pipe on top of the support plate. The second winding wheel rotates and winds up the first wire rope. The threaded rod rotates synchronously, driving two sets of sliders to move in opposite directions. The pull rod pulls the assembly of the first connecting plate, the horizontal plate, and the second clamping plate to the left, clamping the fire-fighting pipe on both sides. The first winding wheel then rotates and winds up the first wire rope, pulling the assembly of the second sliding frame, the second winding wheel, and the threaded rod upwards. This causes the second sliding frame to move upwards along the first sliding frame until it is against the top wall of the first sliding frame. The first winding wheel continues to wind up the first wire rope, causing the second sliding frame and the first sliding frame to move upwards synchronously along the vertical plate until the fire-fighting pipe is lifted to the required height. This allows the support frame assembly to be telescopic, lifting the fire-fighting pipe to different heights.

[0018] 3. This foldable fire-fighting pipe lifting device releases the steel wire rope by rotating the second winding wheel, causing the second clamp to move to the right. The clamps then release their grip on the fire-fighting pipe. Simultaneously, as part of the first steel wire rope is released, the sliding frames one and two move downwards, causing the support plate, clamps one and two to move downwards and separate from the fire-fighting pipe. This achieves the purpose of automatically releasing the clamp on the fire-fighting pipe and moving it downwards to separate it. The tight clamping of the fire-fighting pipe ensures it will not fall during lifting and movement, providing high safety. Furthermore, the automatic release of the clamp makes the operation convenient and quick. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figure 1 A foldable fire pipe installation and lifting device includes a traveling vehicle 100. A support frame assembly 200 is hinged to the left side of the traveling vehicle 100. A folding drive component 300 is provided between the support frame assembly 200 and the traveling vehicle 100. The folding drive component 300 is used to drive the support frame assembly 200 to deflect. A telescopic drive component 400 is provided inside the support frame assembly 200. The telescopic drive component 400 is used to drive the support frame assembly 200 to extend and fold. A clamping component 500 is provided on the right side of the support frame assembly 200. The clamping component 500 is used to clamp and fix the fire pipe. An installation cavity is provided inside the traveling vehicle 100. A lower positioning component 600 is provided in the installation cavity. An upper positioning component 700 is provided on the upper side of the lower positioning component 600 and extends to the top of the traveling vehicle 100. When the support frame assembly 200 is in a vertical state, the lower positioning component 600 is attached to the left side of the bottom end of the support frame assembly 200.

[0040] Please see Figures 1-2 A traction hook 101 is welded to the left end of the traveling vehicle 100. Wheels 102 are installed at the bottom of both the traveling vehicle 100 and the bottom left end of the traction hook 101. A set of wheels 102 is installed at each of the four corners of the traveling vehicle 100's bottom, and another set of wheels 102 is installed at the bottom left end of the traction hook 101, for a total of five sets of wheels 102. The wheels 102 can be omnidirectional wheels with brakes, as is available in the prior art. By positioning the traction hook 101 at the left end of the traveling vehicle 100, the center of gravity of the device remains between the five sets of wheels 102 during the deflection of the support frame assembly 200, preventing tipping. The top of the traction hook 101 has two sets of guide grooves 103 and one set of guide grooves 104 that communicate with the mounting cavity. The two sets of guide grooves 103 are located to the left of the guide groove 104. The two sets of guide grooves 103 guide the lower positioning member 600, and the guide groove 104 guides the upper positioning member 700.

[0041] Please see Figures 2-3The support frame assembly 200 includes two sets of upright plates 201 hinged to the left side of the traveling vehicle 100. Two sets of reinforcing plates 202 are welded between the left sides of the two sets of upright plates 201, connecting the two sets of upright plates 201 together. A sliding frame 203 is slidably connected between the two sets of upright plates 201. A sliding groove 2011 is provided on the opposite side of the two sets of upright plates 201, located above a baffle 204. Sliding strips 2031 are fixedly installed on the bottom of the front and rear sides of the sliding frame 203, and the sliding strips 2031 are adapted to slide with the sliding groove 2011. A baffle 204 is welded between the lower halves of the two sets of upright plates 201, located below the sliding frame 203, and the baffle 204 blocks the sliding frame 203. Sliding frame one 203 is slidably connected to sliding frame two 205. Two sets of support plates 206, distributed front and rear, are fixedly installed on the bottom right side of sliding frame two 205. The support plates 206 are used to support the fire-fighting pipes. Guide rails 2032 are fixedly installed on both the front and rear side walls of sliding frame one 203. Sliding grooves 2051 are opened on both the front and rear sides of sliding frame two 205, and the guide rails 2032 slide in accordance with the sliding grooves 2051. The cross-sections of both the sliding bar 2031 and the guide rail 2032 are isosceles trapezoids.

[0042] Please see Figure 2 The folding drive component 300 includes a sleeve 301 fixedly installed on opposite sides of two sets of upright plates 201. The axis of the sleeve 301 coincides with the edge of the upper left side of the traveling vehicle 100. A fixed shaft 302 is fixedly installed through the upper left side of the traveling vehicle 100, and the sleeve 301 is sleeved on the outside of the fixed shaft 302. Thus, when the upright plate 201 deflects relative to the traveling vehicle 100, the sleeve 301 rotates on the outside of the fixed shaft 302. When the upright plate 201 deflects to a vertical position, the bottom right side of the upright plate 201 abuts against the surface of the left end of the traveling vehicle 100.

[0043] A guide frame 303 is provided on the bottom side of the upright plate 201. The guide frame 303 is located below the sleeve 301. A sliding column 304 is slidably connected inside the guide frame 303. Two sets of hydraulic cylinders 305 are provided inside the mounting cavity of the traveling vehicle 100. The output end of the hydraulic cylinder 305 passes through the left end of the traveling vehicle 100 and is rotatably connected to the surface of the sliding column 304. The output end of the hydraulic cylinder 305 is rotatably connected to the sliding column 304 through a ring structure, which is sleeved on the outside of the sliding column 304. By extending or retracting the output end of the hydraulic cylinder 305, the sliding column 304 is pushed or pulled, causing the upright plate 201 to deflect. At the same time, the sliding column 304 slides inside the guide frame 303.

[0044] Please see Figures 4-5The telescopic drive component 400 includes a mounting base 401 fixedly installed on the surface of the upper reinforcing plate 202. A winding wheel 402 is disposed above the mounting base 401, and a motor 408 is disposed at the center of the winding wheel 402. The motor 408 is used to drive the winding wheel 402 to rotate forward or backward. A steel wire rope 403 is wound around the surface of the winding wheel 402. One end of the steel wire rope 403 is fixed to the surface of the winding wheel 402, and part of the steel wire rope 403 is wound on the winding wheel 402. A movable pulley 404 is rotatably connected to the bottom left side of the sliding frame 203. A notch is provided at the top of the lower reinforcing plate 202 to avoid the movable pulley 404. When the sliding frame 203 is attached to the top of the baffle 204, the movable pulley 404 is located within the notch. A fixed pulley 405 is rotatably connected to the top of sliding frame 203. A take-up wheel 406 is provided inside sliding frame 205. A threaded rod 407 is fixedly fixed through the center of take-up wheel 406. The threaded rod 407 has threaded grooves with opposite thread directions on the surfaces on both sides of take-up wheel 406. The threaded rod 407 is rotatably connected to the front and rear side walls of sliding frame 205. Wire rope 403 passes over the lower surface of movable pulley 404, then passes over the upper surface of fixed pulley 405, and finally winds onto the surface of take-up wheel 406. The other end of wire rope 403 is fixedly installed on the surface of take-up wheel 406, and part of wire rope 403 is wound onto the surface of take-up wheel 406. Wire rope 403 is slidably connected through the top of sliding frame 203 and the top of sliding frame 205.

[0045] Please see Figures 4-5 The wire rope 403 is rotated twice by the cooperation of the movable pulley 404 and the fixed pulley 405. When the winding wheel 402 rotates counterclockwise to wind the wire rope 403, the movable pulley 404 pulls the assembly of the winding wheel 406, the threaded rod 407 and the sliding frame 205 upward, so that the sliding frame 205 moves upward relative to the sliding frame 203 until the sliding frame 205 is in contact with the top wall of the sliding frame 203. At this time, when the winding wheel 402 continues to wind the wire rope 403, the sliding frame 203 and the sliding frame 205 move upward synchronously, that is, the assembly of the sliding frame 203 and the sliding frame 205 moves upward relative to the upright plate 201 until the slide bar 2031 is in contact with the top wall of the slide groove 2011.

[0046] By rotating the winding wheel 402 clockwise, the wire rope 403 is released, and the sliding frame 203 and the sliding frame 205 move downward under the action of gravity.

[0047] Please see Figures 4-5To address the issue of corrosion occurring between the upright plate 201, sliding frame one 203, and sliding frame two 205, making it difficult for them to move downwards under gravity, the following embodiment is provided: Both ends of the winding wheel one 402 are coaxially fixed with winding wheels three 409. The diameter of the winding wheel one 402 is twice the diameter of the winding wheels three 409. A motor one 408 is provided at one end of the assembly of the winding wheel one 402 and the two sets of winding wheels three 409. The motor one 408 is fixedly mounted on the mounting base 40. 1. Top: Two sets of winding reels 409 are each wound with wire rope 410. On the left side of the lower reinforcing plate 202, two sets of fixed pulleys 411 are arranged front-to-back, with their assembly extending through the reinforcing plate 202. The wire rope 410 passes over the lower surface of the two sets of fixed pulleys 411 and slides through and connects to the surface of the baffle 204 and the lower part of the sliding frame 203, finally being fixedly installed at the bottom of the sliding frame 205. When the winding reel 402 rotates counterclockwise to wind the wire rope 403, the winding reel 409 rotates counterclockwise to release the wire rope 410. Similarly, when the winding reel 402 rotates clockwise to release the wire rope 403, the winding reel 409 rotates clockwise to wind the wire rope 410. When corrosion occurs between sliding frame 1 203 and the upright plate 201, and between sliding frame 2 205 and sliding frame 1 203, sliding frame 1 203 and sliding frame 2 205 may encounter descent obstacles under gravity alone. Therefore, by winding the wire rope 2 410 with the winding wheel 3 409, a downward pulling force can be applied to sliding frame 2 205 through the wire rope 2 410, making the descent of sliding frame 2 205 more stable. Furthermore, when sliding frame 2 205 slides to the bottom wall of sliding frame 1 203, it can drive sliding frame 1 203 to move downward synchronously.

[0048] Please see Figures 6-7 The clamping assembly 500 includes a clamping plate 501 fixedly installed on the top of two sets of support plates 206, a clamping plate 502 slidably connected between the two sets of support plates 206, two sets of horizontal plates 503 fixedly installed on the bottom left side of the clamping plate 502, and a connecting plate 504 fixedly installed on the left end of the two sets of horizontal plates 503. The connecting plate 504 is located to the left of the clamping plate 501, the horizontal plates 503 are located below the clamping plate 501, and the bottom of the clamping plate 502 is flush with the bottom of the support plate 206. The lower right side of the clamping plate 501 and the upper left side of the clamping plate 502 are provided with arc-shaped surfaces, so that when the clamping plate 501 and the clamping plate 502 are clamped on both sides of the fire pipe, they can fit tightly against the fire pipe.

[0049] Two sets of tie rods 505 are hinged to the left side of the connecting plate 504. A set of sliders 506 is hinged to the other end of each tie rod 505. Threaded holes are formed on the surface of each slider 506. The two sets of sliders 506 are threaded to the front and rear halves of the threaded rod 407 through these holes. Guide rods 507 are fixedly installed on the front and rear side walls of the sliding frame 205. The guide rods 507 pass through the sliders 506, and the sliders 506 are slidably connected to the guide rods 507. Thus, when the assembly of the winding wheel 206 and the threaded rod 407 rotates, it drives the two sets of sliders 506 to move towards or away from each other. When the winding wheel 206 rotates and winds up the wire rope 403, the two sets of sliders 506 move away from each other and, through the connecting action of the tie rods 505, pull the clamping plate 502 to the left, thereby reducing the distance between the clamping plates 501 and 502 and clamping the fire-fighting pipe. A gear 508 is fixedly installed at one end of the threaded rod 407. A gear 509 meshes with the upper side of the gear 508. A motor 510 is fixedly installed at the center of the gear 509.

[0050] Please see Figures 8-10 The lower positioning component 600 includes a vertical plate 601 that is slidably connected through the guide groove 103. A connecting plate 602 is fixedly installed at the top of the two sets of vertical plates 601. When the support plate 206 is attached to the top of the traveling vehicle 100, the connecting plate 602 is located between the two sets of support plates 206, and the height of the connecting plate 602 is less than the height of the clamping plate 502.

[0051] Connecting plate 2 602 is attached to the top of the traveling vehicle 100, and connecting plate 3 603 is fixedly installed between the two sets of vertical plates 601. Connecting plate 3 603 is attached to the top wall of the mounting cavity, so that the vertical plates 601 are clamped on the traveling vehicle 100 by the cooperation of connecting plate 2 602 and connecting plate 3 603, and the vertical plates 601 slide stably on the guide groove 103.

[0052] A base 604 is fixedly installed on the right side of the bottom of the two sets of vertical plates 601. Two sets of connecting rods 605 are fixedly installed on the left side of the base 604. The connecting rods 605 pass through the left end of the traveling vehicle 100 and extend to the left side of the traveling vehicle 100. A pressure plate 606 is fixedly installed on the left end of the two sets of connecting rods 605. Two sets of through grooves 607 are opened through the surface of the pressure plate 606. The pressure plate 606 is sleeved on the outer side of both ends of the traction hook 101 through the through grooves 607.

[0053] The bottom of the reinforcing plate 202 located on the lower side has two sets of clearance grooves 207, which are used to avoid the two ends of the traction hook 101. The pressure plate 606 is attached to the left side of the bottommost reinforcing plate 202. A rack plate 608 is fixedly installed on the top of the base 604. A gear 609 is meshed on the top of the rack plate 608. The gear 609 is rotatably connected between the front and rear side walls of the mounting cavity.

[0054] Please see Figures 8-10The upper positioning component 700 includes a slide block 701 that is slidably connected within the guide groove 104. The upper half of the slide block 701 is slidably connected within the guide groove 104, and the lower half is attached to the top wall of the mounting cavity. A trapezoidal strip 702 is fixedly installed on the top of the slide block 701, and the trapezoidal strip 702 is attached to the top of the traveling vehicle 100.

[0055] A trapezoidal strip 703 extending to the left is fixedly installed on the top of the trapezoidal strip 702. The distance between the bottom of the trapezoidal strip 703 and the traveling vehicle 100 is greater than the height of the clamping plate 502. This prevents the trapezoidal strip 703 from colliding with the clamping plate 502 when the support plate 206 is attached to the surface of the traveling vehicle 100 and the clamping plate 502 moves to the right along the support plate 206.

[0056] A slide plate 704 is fixedly installed at the bottom of the slide block 701. The slide plate 704 passes between the two sets of vertical plates 601. A rack plate 705 is fixedly installed at the bottom of the slide plate 704, and the rack plate 705 meshes with the top of the gear 609. When the clamping plate 502 moves to the right against the top of the traveling vehicle 100, it pushes the connecting plate 602 to the right, causing the assembly of the base 604 and the rack plate 608 to move to the right, driving the gear 609 to rotate counterclockwise. This, in turn, causes the assembly of the rack plate 705 and the slide plate 704 to move to the left. That is, the moving direction of the connecting plate 602 is opposite to that of the trapezoidal bar 702.

[0057] A guide groove 706 is formed through the surface of trapezoidal strip 702. An arched plate 707 is slidably connected through the guide groove 706. A spring 708 is fixedly installed between the arched plate 707 and the top wall of the guide groove 706. An F-shaped plate 709 is fixedly installed on the right side of connecting plate 602. The F-shaped plate 709 fits against the side of trapezoidal strip 702. An inclined surface is provided on the upper right end of the F-shaped plate 709. Both ends of the arched plate 707 are arc-shaped surfaces. A positioning groove adapted to the end of the arched plate 707 is provided on the top of the F-shaped plate 709. The end of the arched plate 707 is inserted into the positioning groove. Thus, when connecting plate 602 and trapezoidal strip 702 move towards each other, the inclined surface at the end of the F-shaped plate 709 presses upward against the end of the arched plate 707, causing the spring 708 to contract. Subsequently, when the end of the arched plate 707 moves to the upper part of the positioning groove, the arched plate 707 moves downward and inserts into the positioning groove under the elastic action of the spring 708.

[0058] In use, the motor 408 drives the winding wheel 402 to rotate, winding the wire rope 403. The wire rope 403 pulls the assembly of the sliding frame 205, the winding wheel 406 and the threaded rod 407 upward until the sliding frame 205 is attached to the top wall of the sliding frame 203. At this time, the sliding frame 203 is inside the upright plate 201 and the sliding frame 205 is inside the top of the sliding frame 203.

[0059] Then, by extending the output end of the hydraulic cylinder 305, the sliding column 304 is pushed to the left, so that the sliding column 304 slides along the guide frame 303. At the same time, the vertical plate 201 is pushed to rotate clockwise around the axis of the sleeve 301, so that the assembly of the vertical plate 201 and the sliding frame 203 fits against the top of the trapezoidal strip 703. The assembly of the sliding frame 205 and the support plate 206 is located at the upper right of the right end of the traveling vehicle 100, thereby reducing the height of the device and making it easier to pass through passages with lower door heights.

[0060] Before lifting the fire pipeline: First, the output end of the hydraulic cylinder 305 retracts, pulling the sliding column 304. While the sliding column 304 slides along the guide frame 303, it drives the upright plate 201 to deflect counterclockwise until the bottom end of the upright plate 201 is attached to the left side of the traveling vehicle 100, so that the upright plate 201 is in a vertical state.

[0061] Then, the motor 408 drives the take-up reel 402 to rotate in the opposite direction, releasing the wire rope 403. Under the action of gravity, the assembly of the sliding frame 205 and the pallet 206 moves downward until the pallet 206 is attached to the top of the traveling vehicle 100. Then, the motor 510 drives the gear 509 to rotate, causing the assembly of gear 508, threaded rod 407 and take-up reel 406 to rotate. The take-up reel 406 releases the wire rope 403 on its surface. Blocks 506 move towards each other, and through the connecting action of pull rod 505, drive the assembly of connecting plate 1 504, horizontal plate 503 and clamping plate 2 502 to move to the right. Clamping plate 2 502 pushes connecting plate 2 602 to the right, causing the assembly of connecting rod 605 and pressure plate 606 to move to the right. Pressure plate 606 fits against the surface of reinforcing plate 202 located on the lower side, and cooperates with the left end of traveling vehicle 100, so that pressure plate 606 and traveling vehicle 100 are clamped on both sides of the bottom end of the assembly of vertical plate 201 and reinforcing plate 202.

[0062] When connecting plate 2 602 moves to the right, base 604 and rack plate 1 608 move to the right. This, combined with the meshing of gear 3 609 and rack plate 1 608, causes gear 3 609 to rotate counterclockwise, moving the assembly of insert plate 704 and rack plate 2 705 to the left. This causes connecting plate 2 602 and trapezoidal strip 1 702 to move towards each other. During this process, the right end of F-shaped plate 709 pushes the end of arched plate 707 upwards. Arched plate 707 slides upwards along guide groove 3 706, compressing spring 708. When the end of arched plate 707 reaches the positioning groove at the top of F-shaped plate 709, under the elastic action of spring 708, arched plate 707 moves downwards and inserts into the positioning groove. This prevents trapezoidal strip 1 702 and connecting plate 2 602 from moving, maintaining the blocking effect of pressure plate 606 on the side of reinforcing plate 202.

[0063] When lifting the fire-fighting pipeline: the fire-fighting pipeline is placed on top of the support plate 206. The winding wheel 406 rotates and winds up the wire rope 403. The threaded rod 407 rotates synchronously and drives the two sets of sliders 506 to move in opposite directions. The pull rod 505 pulls the assembly of the connecting plate 504, the horizontal plate 503 and the clamping plate 502 to the left, so that the clamping plate 501 and the clamping plate 502 clamp the fire-fighting pipeline on both sides.

[0064] Then, by rotating the first winding wheel 402, the first wire rope 403 is wound up. The first wire rope 403 pulls the assembly of the second sliding frame 205, the second winding wheel 406 and the threaded rod 407 upward, so that the second sliding frame 205 moves upward along the first sliding frame 203 until the second sliding frame 205 is attached to the top wall of the first sliding frame 203. The first winding wheel 402 continues to wind up the first wire rope 403, so that the second sliding frame 205 and the first sliding frame 203 move upward synchronously along the upright plate 201 until the fire pipe is raised to the required height. Then, the traveling vehicle 100 is pushed to move on the ground so that both ends of the fire pipe are inserted into the pre-set frame on the ceiling.

[0065] Then, by rotating the second winding wheel 406, the first wire rope 403 is released, causing the second clamping plate 502 to move to the right. The first clamping plate 501 and the second clamping plate 502 no longer clamp the fire pipe. At the same time, as part of the first wire rope 403 is released, the first sliding frame 203 and the second sliding frame 205 move downward, causing the support plate 206, the first clamping plate 501 and the second clamping plate 502 to move downward and separate from the fire pipe.
