Description

Technical Field

[0001] This invention relates to the field of continuous reforming reactors, and more specifically to a tooling platform for the installation and maintenance of reactors in continuous reforming units. Background Technology

[0002] In the petrochemical industry, the installation and maintenance of internal parts of continuous reforming reactors are often carried out using electric hoists and suspended platforms, which is disadvantageous for construction processes with strict safety requirements, tight schedules, and heavy workloads.

[0003] Traditional processes using electric hoists with suspended platforms present several technical bottlenecks: First, securing the electric hoist requires setting up anchor points at the top of the tower, which is not only time-consuming and labor-intensive but also poses risks such as falls from height. Second, with reactor heights ranging from 17 to 23 meters, repeated up-and-down movements of the electric hoist and suspended platform increase the risk of mechanical failure, platform swaying, and falls from height. Third, traditional processes only support 1-2 people working simultaneously, resulting in low efficiency. Fourth, as reactor diameter increases, the suspended platform cannot be quickly adjusted, requiring repeated anchor point changes for the electric hoist, leading to poor adaptability and delays in the project schedule. Therefore, a high-safety, high-efficiency installation and maintenance platform needs to be designed.

[0004] To address these issues, those skilled in the art have designed a tooling platform for the installation and maintenance of reactors in continuous reforming units. Summary of the Invention

[0005] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a tooling platform for the installation and maintenance of reactors in continuous reforming units.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: it includes a multi-layer hanging basket, multiple hanging baskets can be stacked and stored together, each hanging basket has a bottom plate, and a staircase for climbing is provided between two adjacent hanging baskets. A protective component is slidably connected to the surface of the staircase, and the protective component is connected to a human safety rope.

[0007] Preferably, the diameters of the multiple suspended baskets increase sequentially from top to bottom, and a sliding connection is formed between adjacent suspended baskets. During the stacking process of multiple suspended baskets, the diameter needs to be continuously expanded to facilitate stacking, and the stacking method is through sliding.

[0008] Preferably, the suspended platform is surrounded by side rails and side plates, which alternately surround the outside of the suspended platform. A guardrail is provided between the side rails and side plates. When sliding, the side rails slide against the sliders on the side plates. The guardrail between the side rails and side plates also serves as a protective measure.

[0009] Preferably, the side panel of the lower suspended basket is slidably connected to the upper side rail, and a channel is opened on the bottom plate. The channels on the bottom plates of each suspended basket correspond to each other. The stairs pass through the channels on each bottom plate. The channels on the bottom plate adopt a square channel structure. The size of the channels can accommodate a person to pass through. And each channel corresponds to each other, ensuring that a person can climb the stairs in a straight upward manner.

[0010] Preferably, the staircase is a foldable structure, and the folding point of the staircase is located at the center of two adjacent base plates. The foldable structure of the staircase can be synchronized with the stacking of the suspended baskets, and the staircase is also the only passage for the suspended baskets to move between each other.

[0011] Preferably, the protective component includes a side frame and a magnetic plate. The side frame is clamped on both sides of the staircase, and the magnetic plate is located on the surface of the staircase. A connecting buckle for connecting to a safety rope is provided in the middle of the magnetic plate. The protective component can be clamped on the staircase and connected to the safety rope of the person to prevent the person from falling during operation.

[0012] Preferably, a spring is provided between the side frame and the magnetic plate, and the magnetic plate and the side frame are joined by mortise and tenon joints on both sides, with the spring located inside the mortise and tenon structure. The spring is hidden inside the mortise and tenon structure, and the side frames on both sides are clamped to the stairs by friction. The spring can pull the side frames to increase the pressure on the stairs.

[0013] Preferably, the protective assembly further includes a seat plate rotatably connected to the magnetic suction plate, and the seat plate and the magnetic suction plate form a magnetic adsorption structure. The seat plate and the magnetic suction plate are provided with pull ropes, allowing the seat plate to be attached to the magnetic suction plate. When the worker is injured or in other danger, the seat plate can be lowered, allowing the worker to sit on it, and then the electric hoist can pull it up along the staircase.

[0014] Preferably, the seat plate has a notch in the middle, and the notch is movably connected to the safety rope. The maximum angle between the seat plate and the magnetic plate is 90 degrees. The notch in the middle of the seat plate does not affect the operator from sitting on its surface. The notch is designed instead of drilling to avoid the problem of the seat plate getting tangled with the safety rope when it is lowered.

[0015] Preferably, when the suspended baskets are stacked, the side frame is located at the bend in the middle of the staircase, so that the staircase cannot be bent or folded and the suspended baskets cannot be stacked. By clamping the side frame in the middle of the staircase, the suspended baskets can be prevented from being stacked, thus preventing workers from being crushed due to accidental folding without leaving the platform.

[0016] The beneficial effects of the present invention are as follows: Traditional maintenance platforms are relatively high, and the height of the crane needs to exceed the sum of the height of the maintenance platform and the height of the reactor in order to lift the maintenance platform into the reactor. However, the present invention adopts a foldable structure, so the height of the crane only needs to exceed the sum of the height of the folded platform and the height of the reactor, which greatly reduces the height requirement of the crane.

[0017] Secondly, in response to potential safety issues arising from platform folding, a protective component was designed. Since the stairs also need to be folded, the protective component can be installed on the stairs as an anchor point for the safety rope. If the tower crane operator misoperates and begins to fold the platform while others are working, the protective component will be stuck on the stairs, preventing the stairs from folding and thus also stopping the platform from being crushed during folding.

[0018] Secondly, because the platform uses stairs for going up and down, if someone is injured on one floor and cannot climb the stairs, people on the upper and lower floors can help them sit on the seat extended by the protective components and pull them up the stairs using an electric hoist, thus avoiding the problem that the equipment is difficult to use for rescue.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting the present patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0030] In the description of this invention, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating a connection between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] Example 1: This invention provides a tooling platform for the installation and maintenance of reactors in continuous reforming units, such as... Figure 1-5 As shown, it includes a multi-layer hanging basket 1, which can be stacked and stored together. Each hanging basket 1 has a base plate 2 at its bottom. A staircase 3 for climbing is provided between two adjacent hanging baskets 1. A protective component 4 is slidably connected to the surface of the staircase 3 and is connected to a safety rope. The diameter of the multiple hanging baskets 1 increases from top to bottom. Two adjacent hanging baskets 1 are slidably connected. The diameter of the multi-layer hanging baskets 1 needs to be continuously increased during the stacking process to facilitate stacking. The stacking method is through sliding.

[0032] The suspended platform 1 is surrounded by a side slide rail 101 and a side plate 102. The side slide rail 101 and the side plate 102 alternately surround the outside of the suspended platform 1, and a guardrail is provided between the side slide rail 101 and the side plate 102. When sliding, the side slide rail 101 slides against the side slide rail 101 through the slider on the side plate 102, and the guardrail between the side slide rail 101 and the side plate 102 can also play a protective role.

[0033] The side plate 102 of the lower hanging basket 1 is slidably connected to the upper side slide rail 101. The bottom plate 2 has a passage, and the passages on the bottom plate 2 of each hanging basket 1 correspond to each other. The staircase 3 passes through the passage on each bottom plate 2. The passage on the bottom plate 2 adopts a square passage structure. The size of the passage can accommodate a person to pass through. And each passage corresponds to each other, ensuring that a person can climb the stairs in a straight upward manner.

[0034] The staircase 3 is a foldable structure, and the folding point of the staircase 3 is located at the center of two adjacent base plates 2. The foldable structure of the staircase 3 can be synchronized with the stacking of the hanging basket 1, and the staircase 3 is also the only passage for the hanging basket 1 to shuttle between each other.

[0035] The protective component 4 includes a side frame 401 and a magnetic plate 402. The side frame 401 is clamped on both sides of the staircase 3, and the magnetic plate 402 is located on the surface of the staircase 3. A connecting buckle 4021 connected to the safety rope is provided in the middle of the magnetic plate 402. The protective component 4 can be clamped on the staircase 3 and connected to the safety rope of the human body to prevent the person from falling during operation.

[0036] A spring 4011 is provided between the side frame 401 and the magnetic plate 402. The magnetic plate 402 and the side frame 401 form a tenon and mortise joint on both sides, and the spring 4011 is located inside the tenon and mortise structure. The spring 4011 is hidden inside the tenon and mortise structure. The side frames 401 on both sides are clamped to the stair 3 by friction, and the spring 4011 can pull the side frame 401 to increase the pressure on the stair 3.

[0037] The protective assembly 4 also includes a seat plate 403 that is rotatably connected to the magnetic suction plate 402. The seat plate 403 and the magnetic suction plate 402 form a magnetic adsorption structure. The seat plate 403 and the magnetic suction plate 402 are provided with a pull rope 404, which can be attached to the magnetic suction plate 402. When the worker is injured or in other danger, the seat plate 403 can be lowered, and the worker can sit on the seat plate 403. Then, the electric hoist pulls the worker up along the direction of the stairs 3.

[0038] The seat plate 403 has a notch in the middle, and the notch is connected to the safety rope. The maximum angle between the seat plate 403 and the magnetic plate 402 is 90 degrees. The notch in the middle of the seat plate 403 does not affect the operator from sitting on its surface. The notch is designed instead of drilling to avoid the problem of the seat plate 403 getting tangled with the safety rope when it is lowered.

[0039] When the suspended basket 1 is stacked, the side frame 401 is located at the bend in the middle of the staircase 3, which prevents the staircase 3 from bending and folding, and prevents the suspended basket 1 from being stacked. By clamping the middle of the staircase 3, the side frame 401 can prevent the suspended basket 1 from being stacked, and prevent workers from being crushed due to accidental folding without leaving the platform.

[0040] During operation, the equipment is hoisted into the reactor of the continuous reforming unit using a crane. When hoisted in, the unit is in a folded state, and personnel can stand at the highest point of the folded platform and enter the reactor along with the maintenance platform. The entire platform is then fully unfolded downwards, forming a long strip structure. Next, the staircase 3 must be kept straight, and personnel begin to descend to the corresponding floors in sequence to begin work. Before starting work, the protective component 4 needs to be fixed to the staircase 3 of the current floor and connected to the protective component 4 with a safety rope to ensure that personnel will not fall. Furthermore, when the platform is folded, the staircase 3 also needs to be folded synchronously. However, because the protective component 4 is stuck in the middle of the staircase 3, even if the platform is folded, it will get stuck due to the staircase. While climbing the staircase, personnel can simultaneously pull the protective component 4. With the protective component 4 at the bottom and personnel climbing at the top, this also prevents personnel from starting to fold the platform inside the platform, thus avoiding injury from being crushed by the folding mechanism.

[0041] Meanwhile, the protective component 4 also has a seat function. By opening the seat plate 403, the injured person can sit on the seat plate 403. The crane above will pull the protective component 4 upward by using a small electric hoist. The traction position is set on the connecting buckle 4021. The person can sit on the seat plate 403 and be quickly rescued by sliding through the stairs 3, avoiding the problem that the person cannot be rescued on any floor of the basket 1.

[0042] When multiple suspended baskets 1 are stacked, an electric hoist is needed to pull the bottom suspended basket 1. When the bottom suspended basket 1 is lifted upward, it can be stacked upward; conversely, it can be extended downward.

[0043] It should be stated that the above-described specific embodiments are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to the present invention. However, such variations, as long as they do not depart from the spirit of the present invention, should be within the scope of protection of the present invention. Furthermore, some terminology used in this specification and claims is not limiting, but merely for ease of description.
