Description

Technical Field

[0001] The invention belongs to the technical field related to hoisting equipment, and specifically discloses a hoisting equipment for processing watertight doors. Background Art

[0002] Watertight doors refer to watertight metal doors installed on watertight bulkheads and perimeter walls inside ships. There are two types: watertight hinged doors and watertight sliding doors.

[0003] watertight doors, when used on board, are capable of ensuring that any watertight door in a dividing bulkhead is closed when or almost immediately after a breach occurs;

[0004] The existing watertight doors require workers to constantly adjust their positions during installation. However, because the watertight doors have a certain weight, workers need to constantly adjust the positions of the watertight doors during the hoisting process, which makes installation inconvenient. Therefore, we need to make improvements to this. Summary of the invention

At this time, the watertight door body located above the support frame will flip over, and the bottom of the watertight door body is connected to the supporting assembly below, so that the watertight door body can quickly face the installation position. During the flipping process of the watertight door body, the lower end abuts against the outer edge of the door frame, and then the traction mechanism continues to tighten the slide rope, and the moving frame also moves to the front end during the abutment process, so that the watertight door body tilts and slowly becomes vertical. Then the plugs on both sides of the positioning seat are moved out, causing the L-shaped frame to rotate to the other side, the support plate is separated from the watertight door body, and then the watertight door body is positioned to the door frame position. The worker can install the watertight door body at this time. Through this method of guided positioning, the watertight door body can be quickly positioned to the installation position, avoiding the swinging instability of the conventional lifting mechanism, and quickly assisting the workers in the installation operation.

[0027] The driving assembly includes a motor 20 fixedly installed inside one end of the frame rod 9, a screw 24 is fixedly installed on the output shaft of the motor 20, a fixed block is rotatably installed on the end of the screw 24 away from the motor 20, the bottom of the fixed block is fixedly connected to the upper surface of the load-bearing seat 41, guide rails 21 are fixedly installed on the upper surfaces of both sides of the load-bearing seat 41, the bottom frame 23 slides together on the outside of the two sets of guide rails 21, and the bottom frame 23 and the screw 24 are threadedly connected;

[0028] The motor 20 is connected to an external power source and can drive the screw 24 to rotate, so that the base frame 23 slides on the outside of the guide rail 21 for use.

[0029] The traction mechanism includes a suspension rod 40 fixedly mounted on the upper surface of both ends of one side of the frame 28, and a hook column 38 is mounted on the upper inner side of the two suspension rods 40. The inner sides of the two sets of hook columns 38 are threaded with sockets 39, and the ends of the two sets of hook columns 38 away from the suspension rod 40 are fixedly mounted with a sliding rope 37;

[0030] The hook column 38 passes through the eye of the suspension rod 40, and then the socket 39 is spirally inserted into the inner side of the hook column 38 on the passing side, so that the hook column 38 can be stably hung on the suspension rod 40 for later traction.

[0031] L-shaped rods 11 are fixedly installed on the upper surfaces of both ends of the frame rod 9, and a fixed rod 12 is symmetrically installed between the two L-shaped rods 11.

[0035] The positioning assembly includes a positioning hole 29 formed on the upper surface of the wrapping rod 25. A slider 27 is fixedly mounted on one end of the arm 18 away from the bottom plate 7. The inner surface of the slider 27 is slidably fitted with the upper surface of the wrapping rod 25. A screw pin 26 is threadedly inserted through the upper inner side of the slider 27, and the bottom end of the screw pin 26 extends to the inside of one of the positioning holes 29.

[0036] The positioning hole 29 can cooperate with the screw pin 26 to position the slider 27, and the slider 27 can move together with the arm 18, so that the component at the bottom end of the arm 18 can be extended to the bottom of the watertight door body 17 for use.

[0037] The pushing mechanism includes two sets of third hydraulic cylinders 33 respectively fixedly mounted on the upper surface of the bottom plate 7, and the telescopic ends of the two third hydraulic cylinders 33 are commonly mounted with a frame 32, and the outer sides of the two sets of frames 32 are sleeved with a sleeve plate 34, and the inner sides of the two sleeve plates 34 are movably interspersed with a clamping plate 31;

[0038] The third hydraulic cylinder 33 can be provided to support the bottom of the frame 32, and the position of the third hydraulic cylinder 33 after rotation is located at the lower end of the marine door frame, so that when the watertight door body 17 rotates, the bottom can be supported from below;

[0039] The provided clamping plate 31 can prevent the watertight door body 17 from sliding off the surface of the bracket 32 ​​when turning over.

[0040] The stretching mechanism includes first hydraulic cylinders 4 respectively fixedly mounted on the upper surface of the fixed seat 2 and close to the two ends of one side of the support seat 15, and the telescopic ends of the two groups of first hydraulic cylinders 4 are fixedly connected to the moving rod 16, and the inner sides of both ends of the moving rod 16 are slidably inserted with guide rods 3, and the bottom ends of the two guide rods 3 are fixedly connected to the fixed seat 2;

[0041] The first hydraulic cylinder 4 can control the tightening of the sliding rope 37 by driving the moving rod 16 to move up and down;

[0042] The guide rod 3 can locate the position of the moving rod 16 to prevent the sliding cable 37 from shaking during the movement.

[0043] Positioning seats 19 are fixedly installed on the outer walls of both sides of the frame 28 and near the middle. L-shaped frames 10 are rotatably installed on the inner upper parts of the two sets of positioning seats 19. Second hydraulic cylinders 14 are fixedly installed on the inner upper parts of the two L-shaped frames 10. Abutment plates 36 are fixedly installed on the telescopic ends of the two sets of second hydraulic cylinders 14. Insertion blocks 35 are movably inserted on the inner sides of both ends of the positioning seats 19, and one end of the insertion blocks 35 extends to the inside of the L-shaped frame 10.

[0044] The second hydraulic cylinder 14 can press the abutment plate 36 to prevent the watertight door body 17 from tipping over when it is turned over.

[0045] The insert block 35 is used to fix the rotatable L-shaped frame 10, and when pressed, the L-shaped frame 10 can be prevented from rotating.

[0046] Working principle: When installing the watertight door body 17, the watertight door body 17 can be placed on the upper surface of the frame 28 first, and then the frame arm 18 can slide on the outside of the wrapping rod 25 according to the length of the watertight door body 17 until one side of the sleeve plate 34 is in contact with the bottom of the watertight door body 17, and then the third hydraulic cylinder 33 presses the frame seat 32, and then the clamping plate 31 is inserted into the sleeve plate 34, and the clamping plate 31 is in contact with the outer surface of the watertight door body 17. Then the worker rotates the corresponding L-shaped frame 10 to the top of the watertight door body 17, and then inserts the insert block 35 into the positioning seat 19 and the L-shaped frame 10. As a result, when the watertight door body 17 rotates, the L-shaped frame 10 will not move, and the second hydraulic cylinder 14 located inside the L-shaped frame 10 drives the sleeve plate 36 at the telescopic end to press downward, so that the watertight door body 17 can be stably fitted on the upper surface of the frame 28, and finally, the first hydraulic cylinder 4 can be telescopically moved. The sliding rope 37 is gradually tightened, so that the hook column 38 at one end of the sliding rope 37 pulls up the suspension rod 40, and with the cooperation of the connecting arm 22 and the rotating shaft 6, the abutment frame 28 and the watertight door body 17 are lifted upward together. During the gradual movement, the watertight door body 17 tilts, and the lower end of the watertight door body 17 abuts against the outer edge of the door frame during the flipping process. Then the sliding rope 37 is continued to be tightened, and the moving frame 1 also moves toward the front end during the abutting process, so that the watertight door body 17 tilts and slowly becomes vertical. As a result, the watertight door body 17 can be quickly positioned to the position where the door frame is installed. Then, during installation, the worker removes the plug blocks 35 on both sides of the positioning seat 19, causing the L-shaped frame 10 to rotate to the other side, and the abutment plate 36 is separated from the watertight door body 17. Then the worker assists in making the watertight door body 17 fit to the position of the door frame. At this time, the worker can install the watertight door body 17.
