Description

Technical Field

[0001] The utility model belongs to the technical field of ship lifting auxiliary equipment, in particular to a bidirectional movable wire rope outlet protection device. Background Art

[0002] A gantry crane is a boom-type crane mounted on a gantry frame. They are commonly used for cargo handling in ports. The lifting and lowering of the gantry crane's hook assembly and the adjustment of the boom's amplitude are achieved by a motor, coupling, and reduction gearbox installed in the machine room, which drives the wire rope drum in a circular motion in both forward and reverse directions. This in turn rotates the roller assembly connected to the wire rope, raising and lowering the hoisted object and adjusting the boom's amplitude. Because the wire rope must pass through the roof of the machine room and requires sufficient space for movement, rain protection at the wire rope outlet on the machine room roof is essential to prevent damage to electrical equipment and structural components within the room.

[0003] Patent No. 201410509731.9 discloses a linearly movable rainproof device consisting of an upper longitudinal pulley, a lower transverse pulley, and a rainproof curtain. A steel wire rope passes through each pulley and, guided by it, the lower transverse pulley moves back and forth linearly, pulling the curtain to provide a sealed barrier. However, the upper longitudinal pulley and its running track are completely exposed at the top of the device, making the track prone to dust accumulation. This increases the operating resistance of the upper longitudinal pulley, which in turn creates additional resistance to the wire rope. This often results in swaying, blocking, and jamming, posing serious safety risks. Summary of the Invention

[0018] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention.

[0019] like Figures 1 to 6 As shown, the present invention comprises a frame 1, an upper waterproof mechanism 2, and a lower waterproof mechanism 3. The frame 1 covers the deck wire rope outlet and is surrounded by partitions 4. The upper and lower waterproof mechanisms 2 and 3 are respectively located within the frame 1. The frame 1 has an open top. The upper waterproof mechanism 2 includes a telescopic curtain assembly 5, a slide rail 7, and a roller 13 assembly. The ends of the telescopic curtain assembly 5 are fixed to the left and right ends of the top of the frame 1. The slide rails 7 are mounted on the front and rear sides of the top of the frame 1. The openings of the slide rails 7 face downward, preventing rainwater and debris from entering the slide rails 7 and reducing the risk of rust and jamming. The roller 13 assemblies are spaced apart on the front and rear sides of the telescopic curtain assembly 5. The rollers 13 of the roller 13 assembly mate with the slide rails 7, and the wire rope passes through the telescopic curtain assembly 5 from top to bottom, preventing rainwater from falling into the wire rope outlet. A drainage hole is provided at the bottom of the partition 4 to drain the water flowing out of the upper water trough 18 and the lower water trough 19 outside the frame 1.

[0020] The telescopic curtain assembly 5 includes a waterproof curtain 9 and multiple groups of movable rollers. A movable roller is set between two adjacent waterproof curtains 9. The drooping of the waterproof curtain 9 between adjacent movable rollers will form a water guide trough, which is used to flow the collected rainwater into the upper water trough 18. The waterproof curtain 9 is sealed with the edge of the bottom plate 11. Each group of movable rollers includes two parallel rollers 10, a bottom plate 11 and a connecting plate 12. The connecting plate 12 is set at the front and rear ends of the bottom plate 11. The two ends of the roller 10 are connected to the axis of the connecting plate 12. The wire rope passes between the rollers 10. The front and rear ends of the bottom plate 11 are connected to the slide rail 7 through the roller 13 assembly. The upper water trough 18 is set below both sides of the waterproof curtain 9. The upper water trough 18 is fixed to the frame 1.

[0021] Also be provided with water-stop cofferdam 8, described water-stop cofferdam 8 is located at around the wire rope outlet. The rainwater gathered flows downwards to outside the cofferdam from the two ends of the water guide trough, and enters the wire rope outlet with the rainwater that prevents waterproof curtain 9 from blocking.

[0022] Specifically, the roller 13 assembly includes two rollers 13, a connecting shaft 14, and a hook 15. The connecting shaft 14 is connected to the rollers 13 at both ends, and the middle of the connecting shaft 14 is connected to the top of the hook 15. The edges of the waterproof curtain 9 and the top of the base plate 11 are both connected to the connecting shaft 14 via the hook 15. The rollers 13 roll within the slide cavity of the slide rail 7. When the wire rope moves with the top, it drives the movable clamping roller to move. The rollers 13 cooperate with the slide rail 7 to ensure that the movable clamping roller moves left and right on the track. The barrier effect of the waterproof curtain 9 reduces the flow of rainwater into the wire rope outlet.

[0023] Furthermore, to prevent rainwater falling between the rollers 10 from entering the wire rope outlet, a lower waterproof mechanism 3 is provided. This mechanism comprises two tarpaulins, a pressure rod 6, a sliding assembly, and a clamping roller assembly 17. The clamping roller assembly 17 is positioned transversely below the upper waterproof mechanism 2. Its ends are connected to the left and right sides of the frame 1 via sliding assemblies. The clamping roller assembly 17 can move back and forth within the frame. The clamping roller assembly 17 is positioned between the two tarpaulins, with the inner edges of the tarpaulins connected to the clamping roller assembly 17 and the outer edges of the tarpaulins connected to the sides of the frame 1. The pressure rod 6 is positioned above the tarpaulins and presses the middle portion of the tarpaulins downward to form a waterproof trough 16. Below each end of the trough 16 are lower water collection troughs 19, extending beyond the water-stop cofferdam 8. The trough 16 catches rainwater falling between the rollers 10, which then flows through the ends of the trough 16 into the lower water collection trough 19 and out through the drainage holes at the bottom of the partition 4.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
