Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a low-cost crane protection platform device with a novel structure. Background Art

[0002] Marine cranes are specialized cranes used for transport operations in maritime environments. They are primarily used for critical tasks such as cargo transfer between ships, offshore replenishment, and the deployment and recovery of underwater equipment. The unique offshore environment presents significant challenges in controlling marine cranes. Similar to various underactuated cranes on land, the swaying motion of loads during transport must be controlled to ensure positioning accuracy and transport efficiency. Furthermore, because these cranes are mounted on a moving platform, such as a ship, the platform's motion can significantly impact the movement of the load. In many cases, the motion of the load at the lifting and lowering points is inconsistent with the crane's own motion. Specifically, during operation, the crane and receiving vessels experience pitch, roll, and heave with the waves, causing the load to sway. Especially during lifting and lowering, this vessel motion can easily cause the hoisted load to collide with the deck again, or leave a lowered load suspended in the air, threatening operational safety. This coupled motion can be particularly serious during inter-ship ammunition replenishment operations.

[0003] Most of the existing marine crane base column protection platform devices are designed with mesh plates, patterned steel plates or patterned aluminum plates at the bottom of the platform. When the exterior of the crane needs maintenance, maintenance can be carried out by standing on the new protection platform device through an external ladder, which can also protect the safety of the maintenance personnel. The crane protection platform devices that are currently widely used are well known to have irregular shapes of various protection platforms depending on their assembly positions. The actual required shape needs to be cut from the entire mesh plate, patterned steel plate or patterned aluminum plate, and the cut part cannot be reused, that is, the utilization rate is low and the cost is too high. At the same time, the protection platform is easily damaged after long-term use, and it needs to be cut during later maintenance, which makes it inconvenient to maintain it. Utility Model Content

[0052] Example 2

[0053] Based on Example 1, this example introduces the specific structure of the clamping assembly in a new type of low-cost crane protection platform device. Figure 11 As shown, the inner walls of both sides of the pressing seat 23 are rotatably connected to the same bidirectional screw 32, and the outer wall of the bidirectional screw 32 is screwed on two symmetrically arranged threaded sleeves 33, the outer walls of the two threaded sleeves 33 are rotatably connected to a connecting plate 31, one end of the two connecting plates 31 is rotatably connected to the driving seat 27, and a worm gear 34 is fixedly connected to the midpoint of the bidirectional screw 32. The inner wall of one side of the pressing seat 23 is rotatably connected to a worm 35, and the worm 35 and the worm gear 34 are meshed with each other. One end of the worm 35 is fixedly connected to the rotating part 21, and the rotation of the rotating part 21 directly drives the worm 35 to rotate. When the worm 35 rotates, the bidirectional screw 32 is directly driven to rotate through the worm gear 34. When the bidirectional screw 32 rotates, it directly drives the two threaded sleeves 33 to move toward or away from each other. When the two threaded sleeves 33 move toward each other, it is convenient to directly push the driving seat 27 to move through the connecting plate 31. When the driving seat 27 moves, it is convenient to directly drive the contact seat 29 to move through the sliding seat 28.

[0054] Working principle: During installation, first fix the two mounting mechanisms 1 and the two connecting components 3 on the crane body, then install the square steel component 2 on the mounting mechanism 1 and the connecting component 3, insert the two limit seats 8 on the square steel 7 into the mounting seat 10, and the two ends of the square steel 7 are respectively clamped on the U-shaped seats 6 on the two connecting components 3, and then push the adjustment seat 12 to move through the clamping component 20. When the adjustment seat 12 moves, it is convenient to directly drive the wedge-shaped seat 13 to insert into the limit opening 9 on the limit seat 8. Multiple adjustment seats 12 are connected by a connecting frame 18. After the clamping component 20 is adjusted, the locking nut 17 is screwed to the locking screw 22, thereby facilitating the tightening of the adjusting seat 12 to prevent the wedge-shaped seat 13 from disengaging from the limiting opening 9 on the limiting seat 8, and then welding the guardrail 4 to the connecting seat 5 and the mounting seat 10 respectively. The wedge-shaped seat 13 is easily worn when inserted into the limiting opening 9, thereby increasing the gap between the wedge-shaped seat 13 and the limiting opening 9. Therefore, the adjusting screw 38 is driven to rotate by the rotation of the prism 36. When the adjusting screw 38 rotates, the driving sleeve 39 is directly driven to move. When the driving sleeve 39 moves, the angle of the rotating seat 41 is directly adjusted, thereby facilitating the adjustment of the slope of the rotating seat 41, thereby avoiding the occurrence of a gap between the rotating seat 41 and the limiting opening 9.

[0055] When adjusting the pressing assembly 20 in the first embodiment, the rotating part 21 is rotated first. When the rotating part 21 rotates, the gear 2 30 is directly driven to rotate. When the gear 2 30 rotates, it is directly driven through the two gears 1 26. When the two racks 1 26 rotate, the two screws 25 are directly driven to rotate. When the screws 25 rotate, the driving seat 27 is directly driven to drive the sliding seat 28 to move. When the sliding seat 28 moves, the contact seat 29 is directly driven to press against the adjustment seat 12.

[0056] When the clamping assembly 20 in the second embodiment is adjusted, the rotating part 21 is rotated first. When the rotating part 21 rotates, the worm 35 is directly driven to rotate. When the worm 35 rotates, the bidirectional screw 32 is directly driven to rotate through the worm gear 34. When the bidirectional screw 32 rotates, the two threaded sleeves 33 are directly driven to move toward or away from each other. When the two threaded sleeves 33 move toward each other, the driving seat 27 is directly pushed to move through the connecting plate 31 to drive the sliding seat 28 to move. When the sliding seat 28 moves, it directly drives the contact seat 29 to be pressed on the adjustment seat 12.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
