Abstract

This invention discloses a novel tooling for replacing the sealing plate of a pin-driven water-sealing ring cooler. It includes a Z-shaped mobile trolley frame, two V-shaped traveling wheels on the upper side of the frame, and two side-stopping wheels on the lower side of the frame. The V-shaped traveling wheels are attached to the upper edge of the outer side of the water tank and roll along it. The side-stopping wheels are against the lower edge of the inner wall panel of the water tank and roll along it, allowing the tooling to utilize the existing structure of the water tank for load-bearing movement and lateral positioning. During replacement, the tooling is installed at the inlet of the external water tank, the new sealing plate is placed on the frame, the tooling is pushed to the sealing plate installation position and secured, and then the tooling is pushed back to continue transporting the next sealing plate. This invention eliminates the need for multiple additional lifting openings for transporting the sealing plates, improving reinstallation efficiency and positioning accuracy, and reducing the safety risks of lifting and transporting in confined spaces.

Description

Technical Field

[0001] This invention relates to the field of steel equipment maintenance technology, and more specifically, to a novel tooling for replacing the sealing plate of a pin-tooth driven water seal ring cooler. Background Technology

[0002] After a water-sealed ring cooler has been in operation for a long time, the inner and outer ring sealing plates need to be removed, replaced, and reinstalled according to maintenance requirements. Reinstallation of the sealing plates is one of the key procedures in the maintenance process.

[0003] The installation area for the sealing plates in a water-sealed ring cooler is relatively narrow, making it difficult for conventional hoisting equipment to directly access and continuously cover each sealing plate installation location. When manually hoisting new sealing plates in the water tank area, problems such as hoisting difficulties, long maintenance times, high manpower requirements, and inconvenient sealing plate placement often arise. Creating hoisting or transport channels may also require openings at multiple locations, increasing the workload and introducing additional risks associated with working at heights, lifting operations, and working near edges.

[0004] The water-sealed ring cooler itself has a water tank extending circumferentially, with continuous distribution along the upper edge of the outer side of the tank, and the lower edge of the inner wall panel of the tank can also form a continuous guide boundary. How to utilize the existing structure of the water tank to form a transfer path suitable for the bearing, movement, and limiting of the sealing plate without laying additional dedicated tracks is the key to improving the efficiency of sealing plate reinstallation and reducing construction risks. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this invention is to provide a novel special tooling for replacing the sealing plate of a pin-tooth driven water-sealing ring cooler. The tooling utilizes the upper edge of the outer side of the water tank and the inner side wall plate of the water tank to form the basis for its movement and positioning, enabling the new sealing plate to be smoothly transported along the water tank from the inlet of the external water tank to the installation position, thereby improving construction efficiency and positioning accuracy, and reducing the safety risks of hoisting and transporting in confined spaces.

[0006] The present invention adopts the following technical solution:

[0007] This invention discloses a novel special tooling for replacing the sealing plate of a pin-tooth driven water-sealing ring cooler, including a mobile trolley frame, V-shaped running wheels, and side baffle wheels;

[0008] The frame of the mobile trolley is Z-shaped and has a support area for supporting the sealing plate;

[0009] The V-shaped traveling wheels are provided in two, and both V-shaped traveling wheels are rotatably mounted on the upper side of the mobile trolley frame, for hanging on the upper edge of the outer side of the water tank and rolling along the upper edge of the outer side of the water tank.

[0010] The side guard wheel is provided in two parts, and both side guard wheels are rotatably mounted on the lower side of the mobile trolley frame, for abutting against the lower opening of the inner wall panel of the water tank and rolling along the inner wall panel of the water tank;

[0011] The V-shaped traveling wheels form a bearing and traveling engagement with the upper outer edge of the water tank, and the side guard wheels form a lateral limiting engagement with the inner side wall panel of the water tank, so that the moving trolley frame carrying the sealing plate can move along the water tank.

[0012] Furthermore, the two V-shaped running wheels are spaced apart along the moving direction of the mobile trolley frame, and the two side guard wheels are spaced apart along the moving direction of the mobile trolley frame.

[0013] Furthermore, the V-shaped running wheel has a V-shaped groove on its surface, which matches the upper outer edge of the water tank.

[0014] Furthermore, the mobile trolley frame is welded from L70 angle steel.

[0015] Furthermore, both the V-shaped running wheel and the side wheel include a 360° freely steerable wheel body made of 45 steel and a 6305 bearing assembled on the 360° freely steerable wheel body.

[0016] Furthermore, the outer diameter of the 360° freely steerable wheel is 80mm.

[0017] Furthermore, the dimensions of the mobile trolley frame are set according to the outer dimensions of the inner or outer ring sealing plate of the water-sealed ring cooler, so as to support the corresponding inner or outer ring sealing plate.

[0018] Furthermore, during use, the sealing plate is replaced with a special tooling and installed at the inlet of the external water tank of the water-sealed ring cooler, so that the two V-shaped traveling wheels are hung on the upper edge of the outer side of the water tank, and the two side guard wheels are attached to the lower edge of the inner wall of the water tank.

[0019] Place the new sealing plate to be installed on the frame of the mobile trolley;

[0020] The sealing plate is pushed along the water trough to replace the special tooling. The V-shaped traveling wheel rolls along the upper edge of the outer side of the water trough, and the side guard wheel rolls along the inner side wall of the water trough until the new sealing plate is transferred to the sealing plate installation position.

[0021] The new sealing plate is transferred from the mobile trolley frame to the installation position and fixed.

[0022] Replace the sealing plate with a special tool and push it back along the water trough to the inlet of the external water trough.

[0023] Furthermore, before pushing the sealing plate to replace the special tooling, apply lubricating oil to the upper edge of the outer side of the water tank; after completing the installation of one new sealing plate, repeat the steps of placing, transporting, installing and pushing the tooling back to complete the reinstallation of multiple sealing plates in sequence.

[0024] Beneficial effects

[0025] The existing upper edge of the water tank of the water seal ring cooler is used as the running track for the V-shaped traveling wheels, and the inner wall plate of the water tank is used as the limiting and guiding surface for the side guide wheels, so there is no need to lay a special track through the maintenance area.

[0026] The combined action of the V-shaped traveling wheels and the lateral limiting action of the side guard wheels allows the moving trolley frame to move smoothly along the water tank, which helps improve the accuracy of the transfer and positioning of the sealing plate.

[0027] The new sealing plate can be continuously transported from the inlet of the external water tank to the corresponding installation position, reducing the time spent on repeated hoisting and manual handling of the sealing plate in the water tank, and improving the efficiency of sealing plate reinstallation.

[0028] This reduces the need to create openings in multiple locations for hoisting and transporting sealing plates, lowers the safety risks of hoisting, transporting, and working near edges in confined spaces, and reduces the workload of the installation process.

[0029] The tooling is constructed with an angle steel frame and conventional 360° freely steerable wheels and bearings. It has a simple structure and is easy to manufacture and use on site according to the size of the inner or outer ring sealing plate. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] As shown in the figure, an embodiment of the present invention discloses a new type of special tooling for replacing the sealing plate of a pin-tooth driven water seal ring cooler, including a mobile trolley frame 2, V-shaped running wheels 1 and side baffle wheels 3.

[0037] The mobile trolley frame 2 is generally Z-shaped and has a support area for supporting the sealing plate 4;

[0038] Two V-shaped traveling wheels 1 are provided, and both V-shaped traveling wheels 1 are rotatably mounted on the upper side of the mobile trolley frame 2, for hanging on the upper edge of the outer side 5 of the water tank and rolling along the upper edge of the outer side 5 of the water tank.

[0039] Two side guard wheels 3 are provided, and both side guard wheels 3 are rotatably mounted on the lower side of the mobile trolley frame 2, for abutting against the lower opening of the inner wall panel 6 of the water tank and rolling along the inner wall panel of the water tank.

[0040] The V-shaped traveling wheel 1 forms a bearing and traveling cooperation with the upper edge of the outer side 5 of the water tank, and the side stop wheel 3 forms a lateral limiting cooperation with the inner side wall plate of the water tank, so that the moving trolley frame carrying the sealing plate can move along the water tank.

[0041] In this embodiment, the upper edge of the outer side 5 of the water tank and the wall panel of the inner side 6 of the water tank are respectively transformed into a bearing travel reference and a lateral limiting reference. The V-shaped traveling wheel 1 and the side blocking wheel 3 located in different spatial positions are connected into one unit by the Z-shaped moving trolley frame 2, so that the tooling can form a stable transfer path without the need to add a special track through the maintenance area. The two types of rollers bear the vertical load and the lateral constraint respectively, avoiding the offset and jamming caused by a single roller bearing multiple directions at the same time. This constitutes a dual-reference cooperative guiding structure suitable for narrow annular water tank areas.

[0042] In one embodiment of the present invention, two V-shaped running wheels 1 are spaced apart along the moving direction of the mobile trolley frame 2, and two side guard wheels 3 are spaced apart along the moving direction of the mobile trolley frame 2.

[0043] In this embodiment, two V-shaped traveling wheels 1 spaced apart along the direction of movement form front and rear bearing points, and two side stop wheels 3 spaced apart along the direction of movement form front and rear lateral limiting points. These four positions together constrain the movement posture of the moving trolley frame 2. When the load on the sealing plate 4 changes in front-to-back distribution during transport, the front and rear bearing points can disperse local off-center loads, and the front and rear limiting points can suppress frame swaying, thereby improving the stability and positioning accuracy of transport within the narrow water tank area.

[0044] In one embodiment of the present invention, the wheel surface of the V-shaped traveling wheel 1 is provided with a V-shaped wheel groove, and the V-shaped wheel groove is matched with the upper outer edge of the water tank.

[0045] The V-shaped grooves form geometric guides on both sides of the upper edge of the water tank, giving the V-shaped traveling wheel 1 a tendency to automatically maintain its position along the upper edge during rolling. This self-guiding effect, combined with the side guard wheel 3's contact and limiting action on the inner wall of the water tank, forms a composite constraint of upper self-guiding and lower anti-deviation, which can reduce the possibility of the tooling deviating from the predetermined transport path due to uneven force.

[0046] In one embodiment of the present invention, the mobile trolley frame 2 is made of L70 angle steel welded together.

[0047] A Z-shaped mobile trolley frame 2 is formed by welding L70 angle steel, so that the area supporting the sealing plate 4, the installation position of the upper V-shaped traveling wheel 1, and the installation position of the lower side stop wheel 3 are maintained in relative relationship by the same rigid frame. The Z-shaped spatial arrangement can adapt to the height difference of the water tank edge, while retaining the support space for the sealing plate and avoiding the water tank wall panel, making the tooling suitable for installation and movement in the narrow space between existing equipment structures.

[0048] In one embodiment of the present invention, both the V-shaped traveling wheel 1 and the side baffle wheel 3 include a 360° freely rotating wheel body made of 45# steel and a 6305 bearing mounted on the 360° freely rotating wheel body. Common annular coolers have an effective cooling area ranging from 200㎡ to 550㎡. Considering the different specifications, dimensions, and weights of the sealing plates, the corresponding material selection will be adjusted accordingly (for example, the bearing may become 6306 / 6308).

[0049] All ring coolers are ring-shaped. During the process of pushing the sealing plate, the trolley is prone to jamming. The wheels are 360° free-turning wheels, so the efficiency will be higher along the outer edge and inner baffle of the ring (with curvature) water tank.

[0050] The 360° freely rotatable wheels, made of 45# steel, bear the contact load transmitted by the sealing plate 4 and the moving trolley frame 2. A 6305 bearing converts the relative motion between the 360° freely rotatable wheels and the frame into rolling motion, integrating the load-bearing components and drag-reducing components at each traveling and limiting position. This combination reduces manual pushing resistance without adding a complex drive mechanism and maintains the rotational consistency of the V-shaped traveling wheels 1 and the side guard wheels 3 during repeated transport.

[0051] In one embodiment of the present invention, the outer diameter of the 360° freely steerable wheel is 80 mm.

[0052] The outer diameter of the 360° freely rotatable wheel is set to 80mm. This allows the wheel to have a load-bearing cross section while controlling the outer dimensions of the tooling at the edge of the water tank. It also allows the V-shaped traveling wheel 1 and the side-stop wheel 3 to be arranged within the limited space of the upper edge of the outer side of the water tank and the lower opening of the inner sidewall panel, respectively. This dimensional configuration balances rolling throughput, structural compactness, and transport stability under load on the sealing plate 4.

[0053] In one embodiment of the present invention, the dimensions of the mobile trolley frame 2 are set according to the outer dimensions of the inner ring sealing plate or the outer ring sealing plate of the water sealing ring cooler, so as to support the corresponding inner ring sealing plate or the outer ring sealing plate.

[0054] While maintaining the load-bearing relationship between the V-shaped traveling wheels 1 and the upper edge of the outer side of the water tank, and the lateral limiting relationship between the side guard wheels 3 and the inner wall panel of the water tank, the support area of ​​the moving trolley frame 2 is adjusted according to the outer dimensions of the inner or outer ring sealing plate. Thus, the same dual-reference guiding principle can adapt to different sealing plates of the inner and outer rings, reducing the workload of redesigning the entire transfer principle for different installation positions.

[0055] When using it, please follow these steps:

[0056] Replace the sealing plate with a special tooling and install it at the inlet of the external water tank of the water seal ring cooler, so that the two V-shaped traveling wheels are hung on the upper edge of the outer side of the water tank and the two side guard wheels are attached to the lower edge of the inner side wall of the water tank.

[0057] Place the new sealing plate to be installed on the frame of the mobile trolley;

[0058] The sealing plate is pushed along the water trough to replace the special tooling. The V-shaped traveling wheel rolls along the upper edge of the outer side of the water trough, and the side guard wheel rolls along the inner side wall of the water trough until the new sealing plate is transferred to the sealing plate installation position.

[0059] The new sealing plate is transferred from the mobile trolley frame to the installation position and fixed.

[0060] Replace the sealing plate with a special tool and push it back along the water trough to the inlet of the external water trough.

[0061] Before pushing the sealing plate to replace the special tooling, apply lubricating oil to the upper edge of the outer side of the water tank; after completing the installation of one new sealing plate, repeat the steps of placing, transporting, installing and pushing the tooling back to complete the reinstallation of multiple sealing plates in sequence.

[0062] The innovation of this embodiment lies in using the inlet of the external water tank as a fixed loading and return node, forming a cyclical operation path of "loading at the inlet, transferring along the tank, installing at a fixed point, and returning empty." The lubrication of the upper edge of the water tank reduces the rolling resistance of the V-shaped traveling wheels. This cyclical transfer method concentrates the hoisting needs scattered across multiple sealing plate installation locations at the inlet of the external water tank, enabling the tooling to continuously serve the reinstallation of multiple sealing plates, reducing the need for multiple openings and repeated hoisting and relocation.

[0063] The above description is merely a preferred embodiment of the present invention; however, 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 its improved concept, should be covered within the scope of protection of the present invention.
