Description

Technical Field

[0001] The utility model relates to the technical field of river channel construction, in particular to an automatic unhooking water hoisting device. Background Art

[0002] The riverbed is easily eroded under high-speed water flow. In order to reduce riverbed scouring, reduce the amount of water thrown into the dragon mouth, shorten the interception time and reduce the collapse of the dike, large stones and reinforced gabions are used for foot protection and bottom protection before the dike is closed. The bottom protection uses two layers of 2m×1m×1m reinforced gabions, covering an area of ​​30m upstream and downstream of the dike.

[0003] At the same time, in order to reduce the scouring during the closure process, large stones and reinforced gabions are used for protection at different elevations of the right bank of the dike. Large stones are used for protection below 2544.00m, and reinforced gabions with a thickness of 2.0m are used for protection in the range of 2544.00m to 2548.00m. The reinforced gabions are laid in a "one-by-one" manner, rising synchronously with the stone slag thrown into the dike and constructed simultaneously.

[0004] Some rivers do not have the conditions for boat-dropped bottom protection due to their large natural gradient, narrow riverbed, large flow and high flow rate. The large rocks and reinforced gabions for riverbed protection and right bank head protection are placed in layers by manual labor and truck cranes. After the large rocks and reinforced gabions are placed underwater, the traditional construction method requires manual labor to disconnect the truck crane hook from the suspended object and remove it, which is highly dangerous.

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.

[0023] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Further, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-on, one-piece fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0026] Combined with Figure 1 , an automatic unhooking water hoisting device of the present embodiment comprises a lifting body 1, a lifting part 2 is provided in the middle part of the lifting body 1, the lifting body 1 can rotate around the lifting part 2, a hook 3 is provided at the lower end of the lifting body 1, the hook 3 is used to hang heavy objects, one side opening of the hook 3 serves as a hanging inlet and outlet, a counterweight 4 is provided at the upper end of the lifting body 1, the weight of the counterweight 4 is higher than the weight of the hook 3, when no heavy objects are hung, the counterweight 4 is located at the bottom, the hook 3 is located at the top, the center of gravity of the counterweight 4 and the opening of the hook 3 are located on the same side of the lifting body 1, taking the present embodiment as an example, the lifting body 1 is in a C-shaped or nearly C-shaped structure.

[0027] The automatic unhooking water hoisting device is designed as a top-heavy structure. After the load is hoisted to the specified position, the load is lowered. When the load touches the ground and is not affected by external gravity, the hook side of the automatic unhooking water hoisting device automatically flips upwards under the action of its own gravity and can be separated from the load, thereby achieving the purpose of automatic unhooking during water hoisting operations.

[0028] As an optional solution of the utility model, the lifting part 2 is a lifting hole that is opened through the lifting body 1, the shackle of the lifting equipment passes through the lifting hole on the lifting body 1, and the crane wire rope is connected and fixed to the shackle, which has a simple structure, is easy to use and has high stability.

[0029] As an optional solution of the present invention, the center of gravity of the counterweight block 3 is set far away from the hook 2. Because the counterweight block 3 uses the lever principle to lift the hook 3, within a reasonable range, the farther the center of gravity of the counterweight block 3 is from the hook 2, the lighter the weight of the counterweight block 3 is, and the more sensitive it is when lifting the hook 3.

[0030] As an optional solution of the present invention, a cavity 5 is provided inside the counterweight block 4, and a filling port 6 connected to the cavity 5 is provided on the counterweight block 4. The equipment of the cavity 5 can reduce the dead weight of the counterweight block 4. At the construction site, the weight of the counterweight block 4 can be achieved as expected by filling the cavity 5 with stones and soil. The use is very convenient, and it is easy to install and carry, saving materials.

[0031] As an optional solution of the present invention, in order to ensure the structural stability when the cavity 5 is provided inside the counterweight block 4 , a plurality of reinforcing ribs are provided inside the cavity 5 .

[0032] As an optional solution of the utility model, the filling port 6 is detachably connected with a plug 7, and the plug 7 is used to prevent the filler in the cavity 5 from leaking out from the filling port 6. At the same time, it also allows water to be injected into the cavity 5 to fill the gap between the stone and the soil, so that the air in the cavity 5 can be discharged as much as possible. In this embodiment, the plug 7 is a bolt structure, which is connected to the counterweight block 4 by threading, and is very convenient to disassemble and assemble.

[0033] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
