Description

Technical Field

[0001] This utility model relates to the field of hopper technology, and in particular to a hopper for fixed-point stone throwing on water. Background Technology

[0002] Rockfilling on riverbanks (also known as rockfill revetment or rockfill engineering) is a common engineering measure, mainly used to protect and stabilize riverbanks, preventing erosion and damage from water flow, waves, or other external forces. The scouring action of water flow (such as rivers and tides) and waves gradually erodes riverbanks, leading to bank retreat or even collapse. Rockfilling can disperse the impact of water flow, reducing direct scouring of the riverbank and thus protecting its stability. In traditional rockfilling, excavators first load stones into hoppers, then cranes transport the hoppers to a designated location before dropping the stones into the water. However, nowadays, with stones directly loaded into the hoppers, the bottom of the hoppers bears the weight and impact of the stones for extended periods, making them prone to breakage, especially when the hoppers are lifted into the air. If the bottom of the hopper breaks, stones can fall, posing a significant safety hazard. Utility Model Content

[0003] This utility model discloses a hopper for fixed-point stone throwing on water, which solves the problem that the bottom of the hopper is very easy to break due to the long-term bearing of the weight and impact of the stones, which may lead to safety accidents.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A hopper for fixed-point rock throwing on water includes a hopper body with a set of support rods inside. A sliding lifting plate is located below the hopper body, and a vertical plate penetrating the bottom of the hopper body is fixed to the top of the lifting plate. The top of the vertical plate is located above the support rods. Two symmetrical lifting lugs (number 1) are located on one side of the hopper body, with a number 1 steel wire rope fixed to each lug. A hook (number 1) and a second hook are located above the hopper body, with a first lifting plate (number 1) connected to the two first steel wire ropes fixed to the bottom of the first hook. Second lifting lugs are fixed to both sides of the hopper body, with second steel wire ropes fixed to each lug. Second lifting plates (number 2) are fixed to the bottom of each hook (number 2) and connected to the two second steel wire ropes respectively.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] When the hopper body is placed on the stone barge, the lifting plate contacts the bearing surface of the stone barge, causing the lifting plate to move upward. During the process of loading stones into the hopper body, large stones directly contact the vertical plate, preventing direct impact with the bottom of the hopper body and effectively protecting the bottom of the hopper body. When the hopper body is lifted, the lifting plate slides downward, moving the top of the vertical plate below the bearing rod, where the stones are supported by the bearing rod, further reducing the pressure on the bottom of the hopper body. If the bearing rod inside the hopper body breaks or is damaged, it can be repaired promptly. This invention effectively prevents stones from directly impacting the bottom of the hopper body, reduces the pressure on the bottom of the hopper body, improves the service life and safety of the hopper, and avoids the safety hazard of stones falling due to bottom damage.

[0011] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0012] like Figure 1 and Figure 2As shown, this utility model provides a hopper for fixed-point rock throwing on water, including a hopper body 1, a set of bearing rods 2 inside the hopper body 1, a sliding lifting plate 3 below the hopper body 1, a vertical plate 31 that penetrates the bottom of the hopper body 1 fixed to the top of the lifting plate 3, and the top of the vertical plate 31 being above the bearing rods 2; two symmetrical first lifting lugs 4 on one side of the hopper body 1, a first steel wire rope 41 fixed on the first lifting lug 4, a first hook 5 and a second hook 7 on the top of the hopper body 1, a first lifting plate 51 connected to the two first steel wire ropes 41 fixed to the bottom of the first hook 5; second lifting lugs 6 are fixed on both sides of the hopper body 1, a second steel wire rope 61 fixed on the second lifting lug 6, and a second lifting plate 71 connected to the two second steel wire ropes 61 respectively fixed to the bottom of the second hook 7. When the hopper body 1 is placed on the stone-loading boat, the lifting plate 3 contacts the bearing surface of the stone boat, causing the lifting plate 3 to move upward. During the process of loading stones into the hopper body 1, large stones directly contact the top of the vertical plate 31, preventing direct impact with the bottom of the hopper body 1, thus effectively protecting the bottom of the hopper body 1. When the hopper body 1 is lifted, the lifting plate 3 slides downward, causing the top of the vertical plate 31 to move below the bearing rod 2, whereby the stones are supported by the bearing rod 2, further reducing the load on the bottom of the hopper body 1. Pressure; Hook 5 and hook 7 are connected to the external crane winch mechanism via wire ropes. The crane winch mechanism first drives wire rope 41 and wire rope 61 upward through hook 5 and hook 7, causing the hopper body 1 to move upward. When the hopper body 1 moves to the designated position, the crane winch mechanism causes hook 7 to move downward, causing one side of the hopper body 1 to tilt downward until the hopper body 1 is in a vertical state. Then, the stones in the hopper body 1 can fall out of the hopper body 1, completing the stone throwing operation.

[0013] like Figure 1 As shown, two reinforcing plates 8 are fixed to the outer side of the hopper body 1, arranged vertically. The reinforcing plates 8 are U-shaped, and a reinforcing plate 81 is fixed between the two reinforcing plates 8. The reinforcing plates 8 and the reinforcing plate 81 can increase the sturdiness of the hopper body 1.

[0014] like Figure 1As shown, two symmetrical No. 3 lifting lugs 82 are fixed on the upper reinforcing plate 8, and No. 3 steel wire ropes 83 are fixed on the No. 3 lifting lugs 82. A No. 3 hook 9 is provided above the hopper body 1, and a No. 3 lifting plate 91 is fixed to the bottom of the No. 3 hook 9. A No. 4 steel wire rope 92 is fixed to the bottom of the No. 3 lifting plate 91, and the bottom of the No. 4 steel wire rope 92 is connected to the two No. 3 steel wire ropes 83 respectively through connecting rings. The No. 3 hook 9 is also connected to the crane winch mechanism through steel wire ropes. By controlling the crane winch mechanism, when the hopper body 1 rotates around the crane winch mechanism, it prevents the hopper body 1 from moving too far away from the crane winch mechanism, thus limiting the movement of the hopper body 1 and ensuring that it can move to the designated position. Subsequently, the crane winch mechanism controls the No. 2 hook 7 and the No. 3 hook 9 to move downwards simultaneously, while the No. 1 hook 5 remains stationary, so that the hopper body 1 is in a vertical position, allowing the stone to be discharged from the hopper body 1.

[0015] like Figure 1 As shown, the hopper body 1 is inclined on the side away from the first lifting lug 4, and a U-shaped reinforcing rib 12 is fixed on the side of the hopper body 1 away from the first lifting lug 4. The second lifting lug 6 is close to the inclined side of the hopper body 1. When the second lifting hook 7 moves downward, the first lifting hook 5 remains stationary, so that the hopper body 1 can be tilted, allowing the stone to be discharged from the hopper body 1 more effectively and quickly.

[0016] like Figure 2 As shown, two symmetrical fixing strips 21 are fixed inside the hopper body 1, and the bearing rod 2 is fixed between the two fixing strips 21. The fixing strips 21 can increase the firmness of the connection between the bearing rod 2 and the hopper body 1.

[0017] like Figure 1 and Figure 2 As shown, two symmetrical connecting blocks 11 are fixed to the bottom of the hopper body 1, and two sliders 32 are fixed to the top of the lifting plate 3. The bottom of the connecting blocks 11 has a sliding track adapted to the sliders 32. When the lifting plate 3 contacts the ground, the top of the vertical plate 31 is above the bearing rod 2. When the hopper body 1 moves upward, separating the lifting plate 3 from the ground, the sliders 32 slide downward, causing the lifting plate 3 to move the vertical plate 31 downward, so that the top of the vertical plate 31 is below the bearing rod 2. This allows the bearing rod 2 to cooperate with the interior of the hopper body 1 to load the stone.

[0018] like Figure 1 As shown, a rubber pad 33 is fixed to the bottom of the lifting plate 3. The rubber pad 33 can increase the friction when the hopper body 1 is placed on the ground.
