Description
Technical Field
[0001] The utility model relates to the field of hoisting operations for loading rubble onto ships at docks, and in particular to a structure of a hopper-type rubble lifting box with opening and closing function. Background Art
[0002] When constructing new port facilities or expanding existing ones, a large amount of rubble is required to build docks, breakwaters and other related infrastructure. Rubble can be used to stabilize the soil, prevent erosion, and serve as the foundation for other building materials. With the rising sea levels and more frequent extreme weather events brought about by climate change, strengthening coastal protection has become an important task in many regions. Artificial reefs or revetments made of rubble can reduce erosion and protect the coastline from storms and waves. In river regulation projects, rubble is often used to reinforce riverbanks and prevent collapses caused by river water scouring the riverbanks. In addition, in flood-prone areas, by piling up rubble to form a barrier, the impact of floods on surrounding areas can be effectively reduced.
[0003] Due to its low cost and durability, rubble is the preferred material in many engineering projects. When implementing any project involving the hoisting and transporting of rubble by ship, it is necessary to consider operational safety and environmental impact. The traditional hoisting method is to fix the rubble properly by using appropriate binding methods, and the operator hoists, moves and lowers them one by one, which is inefficient and has the risk of scattering and slipping, poor safety, not only affecting the construction progress, but also potentially threatening the surrounding environment and personnel.

Detailed implementation mode
[0031] Embodiment 1
[0032] As Figures 1-8 shown, in a hopper-opening-and-closing type rubble lifting box structure, two grab buckets 2 are symmetrically arranged at the opening at the lower part of the box body 1. The vertices of the two grab buckets 2 are respectively rotationally connected to the two ends at the lower part of the box body 1. One side of the bottom end of the grab bucket 2 is slidably connected to one end of a traction plate 3. Traction mechanisms 4 are symmetrically arranged on both sides of the box body 1. The bottom ends of the two grab buckets 2 are connected to the traction mechanisms 4 through the traction plate 3. The upper ends of the traction mechanisms 4 on both sides are respectively connected to the two ends of a suspension beam 5. A driving device is arranged in the suspension beam 5, and the grab buckets 2 are driven by the traction mechanisms 4 to rotate and open and close along the side walls of the box body 1;
[0033] A lifting mechanism 6 is further arranged above the box body 1 for lifting the box body 1.
[0034] In this application, the hopper-opening-and-closing structure is combined with the lifting of the box body, so that more rubble can be lifted simultaneously during the construction process. Specifically, before lifting, the grab buckets 2 are opened under the action of gravity, the traction plate 3 and the traction mechanisms 4. The lifting mechanism 6 drives the box body 1 to fall above the rubble to be loaded. The driving device in the suspension beam 5 drives the traction mechanisms 4 on both sides of the box body 1 to rise, driving the traction plate 3 to rise vertically. One side of the bottom ends of the two grab buckets 2 connected to the traction plate 3 also rises and rotates around the hinge point between the vertex of the grab bucket 2 and the box body 1 until the hopper is closed. After the lifting mechanism 6 lifts the suspension beam 5 and the box body 1 to the lowering position, the traction mechanism 4 drives the grab buckets 2 to rotate downward and open, and the rubble naturally falls.
[0035] In a preferred solution, the main body of the grab bucket 2 is composed of two symmetric fan-shaped plates and a bottom plate. With the center of the fan-shaped plate as the vertex, a closed bottom plate is arranged on one side clamped by the two fan-shaped plates, and the other side clamped and the bottom end of the arc are both open. The center vertex of the grab bucket 2 is rotationally connected to the lower end of the box body 1, and the open side at the bottom end is slidably connected to the traction plate 3;
[0036] The radius of the fan-shaped plate of the grab bucket 2 is 1 / 2 of the length of the box body 1.
[0037] The fan-shaped plates enable the grab bucket 2 to completely expose the opening at the lower end of the box body 1 at the starting point of rotation when opening, so as to accommodate more rubble. At the closing end of rotation, it can be completely closed to prevent the broken stones from leaking out through the gaps. At the same time, the two grab buckets 2 at both ends do not interfere with each other during the rotation process.
[0038] In a preferred solution, a plurality of ear plates 201 are arranged at the vertex of the grab bucket 2, and a plurality of hinge plates 101 are correspondingly arranged at the lower end of the box body 1. The hinge plates 101 are rotationally connected to the ear plates 201, and the lower end of the box body 1 is arranged inside the two fan-shaped plates of the grab bucket 2.
[0039] By setting the hinge plate 101 and the ear plate 201, the hinged part extends out of the lower end of the box body 1, avoiding interference between the bottom plate of the grab 2 and the bottom of the box body 1 during the rotation of the grab 2. Through multiple sets of hinged structures, the connection between the grab 2 and the box body 1 is made more firm, preventing the hinged parts from falling off due to excessive mass of the rubble.
[0040] In the preferred solution, strip-shaped chutes 301 are symmetrically provided at both ends of the traction plate 3. The open sides at the bottom ends of the two grabs 2 are respectively slidably connected to the chutes 301 at both ends of the traction plate 3, and the length of the chute 301 is adapted to the rotational opening and closing of the grab 2.
[0041] When the bottom end of the fan-shaped plate of the grab 2 rotates around the vertex, a lateral displacement will occur. The strip-shaped chute 301 meets the lateral displacement requirements of the side points at the bottom end of the grab 2, enabling synchronous rotation on both sides.
[0042] In the preferred solution, a traction mechanism 4 is provided above the traction plate 3. One side of the moving block 401 is provided with a pulley 402. Fixed blocks 403 are symmetrically provided in the middle of the top ends on both sides of the box body 1. One end of the traction rope 404 is connected to the lower end of the fixed block 403, and the other end bypasses the lower end of the pulley 402 and passes through the fixed block 403 to be connected to the hanging beam 5.
[0043] Specifically, the fixed point of the pulley structure is set on the box body 1 through the fixed block 403, so that the traction force is distributed to the box body 1. The pulley 402 is a movable pulley, and the force required to lift the traction rope 404 is 1 / 2 of the mass of the lifted rubble, achieving labor saving.
[0044] In the preferred solution, two vertical T-shaped chutes 102 are symmetrically provided in the middle of both side walls of the box body 1. The other side of the moving block 401 is provided with a T-shaped structure, and the moving block 401 is slidably connected to the side wall of the box body 1 through the T-shaped chute 102. By slidably connecting the pulley 402 to the side wall of the box body 1 through the moving block 401, it can only move in the vertical direction, restricting its freedom of movement in the front and back directions, avoiding the shaking generated during the traction and lifting of the rope, making the opening and closing of the grab more stable and the hoisting process safer.
[0045] In the preferred solution, the upper end of the traction plate 3 is connected to the lower end of the moving block 401 through a plurality of connecting rods 7. The number of the connecting rods 7 is at least two, forming a triangular connection structure;
[0046] The vertical projection length of the connecting rod 7 is adapted to the opening and closing of the grab 2, so that the grab 2 is fully opened when the moving block 401 moves to the bottom end of the T-shaped chute 102, and when the moving block 401 moves to the top end of the T-shaped chute 102, the two grabs 2 close the opening at the lower end of the box body 1.
[0047] Specifically, during the rotation of the grab bucket 2, the vertical displacement of the end connected to the traction plate 3 is relatively large. When the grab bucket 2 is fully opened, the traction plate 3 may have already left the lower end of the box body 1. Therefore, the moving block 401 and the connecting rod 7 are introduced. The connecting rod 7 makes up for the height difference of the endpoints generated by the opening of the grab bucket 2, ensuring the perpendicularity limit of the traction plate 3 during the rotation of the grab bucket 2. The connecting rod 7 adopts a triangular connection structure to ensure the parallelism of the traction plate 3 and the stability of the connection between the traction plate 3 and the moving block 401.
[0048] In a preferred solution, a beam collecting hole 405 is provided on one side of the fixed block 403. A runner 406 is provided in the beam collecting hole 405. The traction rope 404 abuts against the outer edge of the runner 406 and passes through the beam collecting hole 405.
[0049] Through the runner 406, the traction rope 404 converges towards the center when passing through the beam collecting hole 405, avoiding friction and wear between the traction rope 404 and the side wall of the fixed block 403, causing potential safety hazards. At the same time, the centering of the traction mechanism 4 is increased, avoiding the skew of the box body 1.
[0050] In a preferred solution, a semi-circular baffle 407 is provided below the outer edge of the pulley 402. The gap distance between the baffle 407 and the lower outer edge of the pulley 402 is less than the diameter of the traction rope 404. The traction rope 404 is arranged between the baffle 407 and the lower groove of the pulley 402. This prevents the traction rope 404 from slipping out of the groove of the pulley 402 and enhances the stability and safety of the structure.
[0051] In a preferred solution, lifting lugs 8 are provided at the four corners of the upper end of the box body 1. The lifting hook 601 passes through the lifting hole 801 and is connected to the lifting lug 8. The lifting mechanism 6 drives the box body 1 to lift and lower;
[0052] The upper end of the lifting beam 5 is connected to the lifting mechanism 6.
[0053] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be based on the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
