Description

Technical Field

[0001] This invention relates to the field of high-altitude operations technology, and in particular to a high-altitude operations platform for a chemical plant flare head. Background Technology

[0002] The current methods for high-altitude operations at the flare head of chemical plants involve erecting scaffolding platforms, using aerial work vehicles, or using cranes in conjunction with suspended baskets for personnel to perform high-altitude operations. For scaffolding erection operations above 120 meters, the difficulty, risk, and efficiency are high. Meanwhile, existing aerial work platforms cannot reach heights of over 120 meters (Zoomlion's domestic platform is 82.3 meters), and Sinopec's safety operation regulations do not allow cranes to be used in conjunction with suspended platforms for high-altitude operations.

[0003] While aerial work platforms and mobile ladders are widely used, they are primarily cage-type ladders or vehicle-mounted mechanisms used for aerial work platforms below 80 meters or for maintenance and inspection of bridges and buildings. They are suitable for relatively regular exterior walls and bridge structures, but cannot solve the problem of inspecting, repairing, and constructing flare heads for chemical plants at heights of up to 120 meters. Moreover, different flare heads have irregular shapes and varying dimensions, requiring separate measurement and design of the dimensions of some components of the work platform of this invention, making the high-altitude maintenance and installation of flare heads extremely difficult.

[0004] Therefore, in order to solve the problem of inconvenience in inspecting, repairing and constructing the flare head of a chemical plant at a height of 120 meters in the prior art, the present invention proposes a high-altitude work platform for the flare head of a chemical plant. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-altitude working platform for the flare head of a chemical plant.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-altitude work platform for a chemical plant flare head includes a straight ladder suspended from the outer wall of the flare head by a suspension mechanism. A kick plate is fixed to one side of the outer wall of the straight ladder, and multiple climbing rods are fixed to the inner wall of the straight ladder. The distance between two climbing rods near the kick plate is greater than or equal to one meter, forming the entrance of the straight ladder. Multiple through holes are opened on both sides of the outer wall of the straight ladder, and height adjustment rods are slidably connected to both sides of the outer wall of the straight ladder. The height adjustment rods are fixed to the inner wall of the through holes by height adjustment bolts. The inner wall of the straight ladder on one side is fixed with a bracket by bolts. The outer wall of the top of the bracket is fixed with a work platform frame that can slide back and forth on the top of the bracket to adjust the distance between it and the torch head. The top of the work platform frame is fixed with a second fixed grid and a first fixed grid. There is a gap between the first fixed grid and the second fixed grid to form a platform entrance for workers to pass through.

[0007] Preferably, a safety railing is fixed to the top outer wall of the bracket, a support rod is fixed to the top outer wall of the safety railing, and wireless video monitoring is installed on the top outer wall of the support rod.

[0008] Furthermore: a safety cage is fixed to the top outer wall of the kick plate, the top outer wall of the safety cage abuts against the bottom outer wall of the bracket, and the top opening of the safety cage is connected to the platform entrance.

[0009] A further preferred embodiment: the bracket has multiple fixing holes on both sides, and the inner walls of the fixing holes are fixed to the corresponding through holes on the outer wall of the straight ladder by bolts.

[0010] As a preferred embodiment of the present invention: the inner wall of the fixing hole is fixed with an inclined support rod by bolts, and the other end of the inclined support rod is fixed with bolts to the corresponding through hole on the outer wall of the straight ladder.

[0011] As a further preferred embodiment of the present invention: a set of connecting blocks is fixed to the top outer wall of the bracket, and a movable grille is rotatably connected to the inner wall of the connecting blocks, with the outer wall of the movable grille covering the top outer wall of the platform entrance.

[0012] As a further embodiment of the present invention: a reinforcing plate is fixed to the top outer wall of the kickboard, one side of the reinforcing plate is fixed to one side of the outer wall of the straight ladder, and a fixing piece is fixed to the bottom end of the height adjustment rod and fixedly connected to the fixed platform.

[0013] Based on the aforementioned scheme: a set of first side plates are fixed to both sides of the straight ladder by bolts, and hooks are fixed to the outer wall of the first side plates. The hooks are attached to the outer circumferential wall of the torch head and the windproof cover.

[0014] Based on the aforementioned scheme, the preferred embodiment is as follows: a set of second side plates are fixed to the outer walls of both sides of the straight ladder by bolts, and a plate buckle is fixed to one side of the outer wall of the second side plate. The plate buckle is hooked onto the tubular lifting lugs fixed to the outer wall of the torch head and the windproof cover.

[0015] The beneficial effects of this invention are as follows: 1. The top and bottom of the aerial work platform, hoisted to the corresponding position on one side of the flare head, are simultaneously supported and secured using height adjustment rods and hooks. Workers then move to the top of the kick plate via the entrance of the straight ladder on one side, climb up to the bottom of the movable grille, push the movable grille upwards to open it, and climb to the top of the second fixed grille through the platform entrance. The movable grille is then replaced on top of the platform entrance. This allows for maintenance and inspection of the flare head and windproof cover on one side via the maintenance platform, composed of the work platform frame, the first fixed grille, the movable grille, and the second fixed grille. This effectively solves the technical and safety problems faced by existing aerial work methods when operating at heights above 120 meters, providing a safe and feasible aerial work platform and improving the efficiency of aerial maintenance of chemical plant flare heads.

[0016] 2. The safety cage located on one side of the straight ladder can shield and protect workers climbing on the side of the straight ladder, preventing the danger of workers accidentally falling from the side of the straight ladder; the safety railing installed on the top of the outer frame of the work platform can also shield and protect workers working on the top of the outer frame of the work platform.

[0017] 3. The position of the outer frame of the work platform relative to the top of the bracket can be adjusted according to the needs of work and maintenance, thereby adjusting the distance between the outer frame of the work platform and the torch head or wind shield. The front-to-back adjustment distance of the outer frame of the work platform relative to the bracket is less than or equal to 0.7m, so as to avoid the outer frame of the work platform extending too far relative to the bracket, which would affect the overall balance and safety of the aerial work platform.

[0018] 4. The relative height between the work platform frame and the bottom of the height adjustment rod can be adjusted by adjusting the relative height between the height adjustment rod and the straight ladder. This allows the relative height between the work platform frame and the flare head to be adjusted, enabling the work platform frame to be supported and installed at the corresponding height on one side of the flare head according to maintenance and construction needs, further improving the applicability of the aerial work platform.

[0019] 5. The second side plates on both sides of the plate buckle can be fixed to the corresponding positions on both sides of the straight ladder or safety railing by bolts. Then, when hoisting the aerial work platform, the plate buckle on one side of the second side plate can be hung on the tubular lifting lug fixed to the outer wall of the flare head or windproof cover. This allows the aerial work platform to be stably hung on flare heads of different structures and models according to maintenance needs, thereby improving the applicability of this aerial work platform.

Detailed Implementation

[0022] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0023] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] Example 1: A high-altitude work platform for a chemical plant flare head, such as... Figure 1-6As shown, the system includes a straight ladder 1 suspended from the outer wall of the flare head 11 via a suspension mechanism. First, workers climb to the top of the fixed platform 2 using a climbing frame set at the bottom of the fixed platform 2. Then, ground workers use cranes or large drones or other aerial work equipment to lift the aerial work platform assembled from the straight ladder 1, height adjustment rod 3, kick plate 4, and bracket 7. Next, the hook 12 on one side of the straight ladder 1 is moved to the outer circumference of the flare head 11 or wind shield 26 and hung on the outer circumference of the flare head 11 or wind shield 26. At this time, the height adjustment rod 3 at the bottom of the straight ladder 1 will abut against the top outer wall of the fixed platform 2. Workers at the top of the fixed platform 2 can then fix the fixing plate 24 at the bottom of the height adjustment rod 3 to the top of the fixed platform 2 by welding or bolting. Thus, the height adjustment rod 3 and the hook 12 simultaneously support and fix the top and bottom of the aerial work platform, completing the fixed installation of the aerial work platform. The inner wall of the straight ladder 1 is fixed with multiple climbing rods 16. The distance between two climbing rods 16 near the kick plate 4 is greater than or equal to one meter, forming the entrance of the straight ladder.

[0025] Then, the staff can move to the top of the kick plate 4 through the entrance of the straight ladder 1, and then climb up to the bottom of the movable grille 17 through the straight ladder 1. After pushing the movable grille 17 up to open it, the movable grille 17 can be removed from the obstruction of the platform entrance 23. Then, climb up to the top of the second fixed grille 21 through the platform entrance 23, and then put the movable grille 17 back on the top of the platform entrance 23. The flare head 11 and wind shield 26 on one side can then be maintained and repaired through the maintenance platform composed of the work platform frame 20, the first fixed grille 18, the movable grille 17 and the second fixed grille 21. A safety cage 5 is fixed to the top outer wall of the kick plate 4. The top outer wall of the safety cage 5 abuts against the bottom outer wall of the bracket 7. The top opening of the safety cage 5 is connected to the platform entrance 23. The safety cage 5 located on one side of the straight ladder 1 can shield and protect the workers climbing on one side of the straight ladder 1, preventing the danger of workers accidentally falling from one side of the straight ladder 1.

[0026] A safety railing 8 is fixed to the top outer wall of the bracket 7, and a support rod 9 is fixed to the top outer wall of the safety railing 8. A wireless video monitoring device 10 is installed on the top outer wall of the support rod 9.

[0027] Meanwhile, the safety guardrail 8 installed on the top of the work platform outer frame 20 can also shield and protect the workers working on the top of the work platform outer frame 20. At the same time, the front and rear positions of the work platform outer frame 20 on the top of the bracket 7 can be adjusted according to the work and maintenance needs, thereby adjusting the distance between the work platform outer frame 20 and the torch head 11 or wind shield 26. The front and rear adjustment distance of the work platform outer frame 20 relative to the bracket 7 is less than or equal to 0.7m, so as to avoid the work platform outer frame 20 extending too far relative to the bracket 7, which would affect the overall balance and safety of the aerial work platform.

[0028] By installing a wireless video monitoring system 10 on top of the safety railing 8, the high-altitude work of the workers can be monitored in real time, ensuring that the hoisting of the aerial work platform is visible and that the operation process of using the aerial work platform is supervised.

[0029] The straight ladder 1 has a set of first side plates 19 fixed to both sides by bolts. The outer wall of the first side plates 19 is fixed with hooks 12, which are hooked to the outer circumference of the torch head 11 and the windproof cover 26. Based on the specific dimensions of the flare head 11 and the wind shield 26, and the maintenance requirements, the hook 12 can be pre-installed with bolts on the first side plate 19 at the corresponding height on one side of the straight ladder 1 and at the corresponding position on the outer wall of the safety railing 8 before hoisting. This allows the aerial work platform to be hung on the corresponding position on the outer wall of the flare head 11 or the wind shield 26 via the hook 12. Subsequently, based on the specific dimensions of the flare head 11 and the wind shield 26, the length of the height adjustment rod 3 extending beyond the bottom of the straight ladder 1 can be adjusted before hoisting. This allows the fixing plate 24 at the bottom of the height adjustment rod 3 to be stably pressed against the fixed platform 2, making it convenient for workers to fix the fixing plate 24 by welding or bolts.

[0030] The inclined support rod 6 can improve the stability of the connection between the straight ladder 1 and the bracket 7. At the same time, it works with the straight ladder 1 to support the other end of the bracket 7, improving the stability of the bracket 7 when working at height. The reinforcing plate 14 can also improve the stability of the connection between the kick plate 4 and the straight ladder 1, and improve the overall structural stability of the aerial work platform.

[0031] In this embodiment, the relative height between the work platform outer frame 20 and the bottom of the height adjustment rod 3 can be adjusted by adjusting the relative height between the height adjustment rod 3 and the straight ladder 1, thereby adjusting the relative height between the work platform outer frame 20 and the torch head 11. This allows the work platform outer frame 20 to be supported and installed at the corresponding height on one side of the torch head 11 according to maintenance and construction needs, further improving the applicability of the aerial work platform.

[0032] In this embodiment, workers can move to the top of the kick plate 4 through the entrance of the straight ladder 1, and then climb up to the bottom of the movable grille 17 through the straight ladder 1. After pushing the movable grille 17 upwards to open it, the movable grille 17 can be removed from the obstruction of the platform entrance 23. Then, they can climb to the top of the second fixed grille 21 through the platform entrance 23. After that, the movable grille 17 can be put back on the top of the platform entrance 23. The flare head 11 and wind shield 26 on one side can then be maintained and repaired through the maintenance platform composed of the work platform frame 20, the first fixed grille 18, the movable grille 17 and the second fixed grille 21.

[0033] The position of the outer frame 20 of the work platform at the top of the bracket 7 can be adjusted according to the work and maintenance needs, thereby adjusting the distance between the outer frame 20 of the work platform and the flare head 11 or the wind shield 26. According to the specific dimensions of the flare head 11 and the wind shield 26 and the maintenance work requirements, the hook 12 can be pre-installed with bolts on the first side plate 19 at the corresponding height on one side of the straight ladder 1 and at the corresponding position on the outer wall of the safety railing 8 before hoisting, so that the aerial work platform can be hung on the corresponding position on the outer wall of the flare head 11 or the wind shield 26 through the hook 12. Then, according to the specific dimensions of the flare head 11 and the wind shield 26, the length of the height adjustment rod 3 extending out of the bottom of the straight ladder 1 can be adjusted before hoisting, so that the fixing plate 24 at the bottom of the height adjustment rod 3 can be stably abutted on the fixed platform 2, making it convenient for workers to fix the fixing plate 24 by welding or bolts.

[0034] Example 2: A high-altitude work platform for a chemical plant flare head, such as... Figure 6 As shown, this embodiment makes the following improvements based on embodiment 1: a set of second side plates 25 are fixed to the outer walls of both sides of the straight ladder 1 by bolts, and a plate buckle 28 is fixed to one side of the outer wall of the second side plate 25. The plate buckle 28 is hung on the tubular lifting lug 27 fixed to the outer wall of the torch head 11 and the windproof cover 26. Meanwhile, the second side plates 25 on both sides of the plate buckle 28 can be fixed to the corresponding positions on both sides of the straight ladder 1 or the safety railing 8 by bolts. Then, when hoisting the aerial work platform, the plate buckle 28 on one side of the second side plate 25 can be hung on the tubular lifting lug 27 fixed on the outer wall of the flare head 11 or the windproof cover 26, so that the aerial work platform can be stably hung on flare heads 11 of different structures and models according to maintenance needs, thereby improving the applicability of this aerial work platform.

[0035] In this embodiment, the second side plates 25 on both sides of the plate buckle 28 can be fixed to the corresponding positions on both sides of the straight ladder 1 or the safety railing 8 by bolts. Then, when hoisting the aerial work platform, the plate buckle 28 on one side of the second side plate 25 is hung on the tubular lifting lug 27 fixed on the outer wall of the flare head 11 or the windproof cover 26, so that the aerial work platform can be stably hung on the flare head 11 of different structures and models according to maintenance needs.

[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
