Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding and repairing, and in particular to a rolling hatch cover sealing rubber installation tool. Background Art

[0002] Hatch cover repairs often involve the replacement of rubber strips. Two common replacement options are lowering the hatch cover to a dock cradle or replacing it onboard the vessel without lowering the hatch cover. Onboard, two methods are typically folding or sideways, and the specific replacement method chosen depends on the specific circumstances. For example, hatch cover replacements involving a high degree of structural integrity are typically performed onboard a dock cradle. However, when dock cradles are under pressure and replacements are less frequent, the vessel is chosen. When the hatch cover is lowered to a dock cradle or sideways onboard for rubber strip replacement, the cover is typically laid flat.

[0003] Usually, the replacement of these types of hatch cover rubber is mainly completed by the inertia of the iron rod's impact. During installation, workers can only swing it upward from the bottom and hit the rubber strip, poking the rubber strip into the rubber groove little by little. This method is not only physically demanding but also inefficient.

[0004] The invention, with application publication number CN107618002A, is titled "Hatch Cover Rubber Installation Tool." It comprises a support sleeve with a telescopic rod inserted therein. The sleeve is provided with a row of evenly spaced positioning holes. The support sleeve and telescopic rod are connected by locking bolts. A lifting mechanism is located at the top of the telescopic rod. The lifting mechanism comprises a support base hinged to a lever with a curved lifting portion at one end. This solution involves pre-placing the rubber in the hatch cover and then using the lifting mechanism described above. However, a certain amount of force must be applied during pre-placing to prevent the rubber from falling out before the lifting mechanism is used. Summary of the Invention

[0005] (1) Technical problems solved

[0006] In view of the deficiencies of the prior art, the present invention provides a rolling hatch cover sealing rubber installation tool, which is used to reduce the labor intensity of workers and improve the installation efficiency of the hatch cover rubber.

[0007] (2) Technical solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a rolling hatch cover sealing rubber installation tool, including a rolling base, a sealing rubber and a hatch cover, the rolling base is provided with a movable support rod which is arranged in an empty sleeve with the rolling base and moves up and down slightly along the rolling base, the outside of the movable support rod is provided with a transmission slide rod which moves up and down along the movable support rod, the transmission slide rod is provided with a lifting rod connected to the transmission slide rod, the lifting rod is provided with a pressure head structure connected to the lifting rod and used to push the sealing rubber into the hatch cover, and the lifting rod is provided with a limiting structure connected to the lifting rod and conflicts with the sealing rubber in the pressure head structure.

[0009] Preferably, the limiting structure includes a movable sleeve that is adjustable for small vertical displacement along the surface of the jacking rod, with adjustment rods connected to both sides of the movable sleeve in a bearing-type manner. A connecting box for supporting a sealing rubber is provided above the adjustment rod, and a support plate is provided within the connecting box that is adjustable for small lateral displacement along the connecting box and contacts the sealing rubber. By installing the movable sleeve at a suitable position on the surface of the jacking rod and securing it with a limiting bolt (not shown), the connecting box is configured to support the sealing rubber on the pressure head structure, and the support plate in the connecting box is aligned with the sealing rubber. At this time, when the sealing rubber is lifted upward by the pressure head structure and pressed into the hatch cover, the rolling balls on the support plate act to spread the sealing rubber during the separation process between the sealing rubber and the support plate, thereby applying sealant to the exterior of the sealing rubber. Once the sealing rubber is pressed into the hatch cover, the sealing performance of the sealing rubber is greatly improved, while reducing the workload of personnel to a certain extent, thereby improving work efficiency.

[0010] Preferably, the connection box is provided with a rubber bladder connected to the support plate. The support plate is provided with a plurality of connecting channels communicating with the rubber bladder, and rolling balls are provided at the liquid outlet ends of the connecting channels. Sealant can be filled into the rubber bladder via a liquid inlet check valve. After the support plate and rolling balls are in contact with the sealing rubber, the sealant enters the rolling balls. At this point, after the sealing rubber is pressed against the hatch cover by the pressing head structure, the rolling balls apply the sealant to the outer wall of the sealing rubber as it moves upward, thereby enhancing the sealing performance of the sealing rubber.

[0011] Preferably, the connection box is provided with a return spring connected to the support plate and capable of elastic return. A liquid inlet check valve connected to the rubber bladder is provided on the outside of the connection box. The connection channels are spaced apart from top to bottom in the support plate. The connection boxes are symmetrically arranged, and a hook spring is provided between the two connection boxes. The provision of the hook spring enables the two connection boxes to clamp the sealing rubber.

[0012] Preferably, a sleeve is provided above the movable sleeve and is hollowly sleeved with the jacking rod. Hydraulic telescopic rods are connected to both sides of the sleeve in a bearing-type manner, and the output end of the hydraulic telescopic rod is connected to the adjusting rod in a bearing-type manner. The outside of the movable sleeve and the outside of the sleeve can be provided with limiting bolts inserted into the jacking rod.

[0013] Preferably, the movable support rod is provided with a hand crank arm which is connected to the movable support rod in a bearing-type manner, and the output end of the hand crank arm is connected to the transmission slide rod through a connecting rod.

[0014] Preferably, the rolling base is provided with a return spring connected to the movable support rod and elastically returning to its original position, and the movable support rod is provided with a plurality of hollow tubes connected to the movable support rod and hollowly sleeved with the transmission slide rod.

[0015] Preferably, the pressure head structure includes a pressure head A, and the pressure head A is arranged at the uppermost end of the jacking rod;

[0016] or,

[0017] The pressure head structure includes a pressure head B, which is arranged at the uppermost end of the lifting rod.

[0018] Preferably, the cross-section of the pressure head A is V-shaped, and the cross-section of the pressure head B is funnel-shaped. The arrangement of the pressure head A and the pressure head B prevents damage to the sealing rubber during the pressing process.

[0019] Preferably, the lifting rod can move up and down along the inside of the transmission slide bar, and the outside of the transmission slide bar can be provided with a limiter for limiting the lifting rod. The limiter is not shown in the figure and is a common bolt.

[0020] plan:

[0021] The tooling design needs to meet the requirements of both construction at the dock platform and construction of the horizontal hatch cover on board. The lower one is used as the standard. Usually, the dock cradle height is about 1250mm, while the height of a single ship is generally greater than this value. Therefore, the design standard is based on the dock cradle height.

[0022] The original construction of this work was mainly done manually, which was labor-intensive and inefficient. The designers adopted the principle of lever and connecting rod transmission, combined with rolling operation to improve efficiency.

[0023] Implementation process:

[0024] The tooling is made of galvanized round pipes, and is manufactured in three specifications with diameters of 42mm, 33mm, and 21mm, taking into account the requirements of weight and strength.

[0025] Instructions for using the tooling: 1. Select a suitable adjustable lifting rod according to the form of the rubber; 2. Measure the distance between the bottom of the hatch cover rubber and the ground, and adjust the limit of the adjustable lifting rod; 3. Choose whether the tooling should move longitudinally or horizontally according to the on-site environment; 4. When the hand crank arm is pressed to lift the tooling under force, the movable support rod will contact the ground to form support, allowing the rubber to enter the rubber groove; when the hand crank arm is released, the movable support rod is separated from the ground by the action of the bottom spring, and the tooling can now be easily pushed to continue the next cycle.

[0026] In the above 4, the sealing rubber can be placed on the pressure head structure through the provided limiting structure, and the support plate in the limiting structure is made to fit with the outside of the sealing rubber. At this time, before the sealing rubber is pressed into the hatch cover through the pressure head structure, the ball in the support plate is made to roll along the surface of the sealing rubber, so that the sealant in the rubber bag can be applied to the surface of the sealing rubber, thereby increasing the sealing performance of the sealing rubber, greatly reducing the work intensity of the personnel, and further improving the work efficiency of the personnel.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] 1. It reduces the difficulty of installing the sealing rubber when the hatch cover is in the flat state, enables single-person operation, and reduces the labor cost of replacing the rubber strip.

[0029] 2. Before the lifting operation, sealant can be applied to the outside of the sealing rubber, and the sealing rubber can be limited at the same time to prevent the sealing rubber from falling off during the lifting process, thereby greatly reducing the labor intensity of the workers and improving their work efficiency.
