Description

Technical Field

[0001] The utility model relates to the technical field of lifting tools, in particular to an anti-falling quick-release lifting tool. Background Art

[0002] Aluminum ingots are a silvery-white mass of aluminum metal obtained through smelting and purification. They are lightweight, have excellent thermal conductivity, and are corrosion-resistant. Aluminum ingots are the third most abundant element in the Earth's crust, after oxygen and silicon. They are an essential raw material for industrial production, including aircraft, auto parts, building materials, and electronic equipment.

[0003] In most cases, the loading and unloading of aluminum ingots are carried out by hoisting with special hoists for aluminum ingots. During the hoisting process of aluminum ingots, since single or multiple bundles of aluminum ingots need to be hoisted with special hoists of different lengths, and these hoists are of an integrated structure, when hoisting aluminum ingots of different numbers of bundles, it is necessary to manually get on and off the vehicle to assist in rotating the hoist and replace the special hoist with the corresponding number of bundles in order to lift the aluminum ingots. During the manual replacement process, it is very easy for the aluminum ingots to fall off the bundle and injure the workers. At the same time, the workers are in close contact with the hoist and there is a risk of falling from a height, which poses a major safety hazard. Utility Model Content

[0004] The utility model aims to provide an anti-falling quick-release sling and a hook, so as to solve the problem that the existing integral sling needs manual assistance for replacement and has a great potential safety hazard in use.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: an anti-falling quick-release sling, including a hook connector, a pair of oppositely arranged hanging rods are provided on the hook connector, the middle part of the hanging rods is rotatably set on the hook connector, and the upper end of the hanging rods is connected to an electric rebound device; it also includes a hook, the lower end of the hook is connected to an aluminum ingot clamp for clamping aluminum ingots, the upper end of the hook is inserted between the two hanging rods and is simultaneously hung and connected with the lower ends of the two hanging rods, there are multiple groups of hooks and aluminum ingot clamps, and the multiple groups of aluminum ingot clamps have lengths for clamping different bundles of aluminum ingots.

[0006] The principle and advantage of this solution are: a sling is formed by combining a hook connector, a hanging rod and a hook, and the hanging rod and the hook are detachably connected, so that when different bundles of aluminum ingots need to be hoisted, different hooks and aluminum ingot clamps can be easily replaced for hoisting. At the same time, the sling in the present scheme can realize the installation of the aluminum ingot clamp by hanging the hanging rod and the hook. When the hook and the aluminum ingot clamp need to be replaced, it is only necessary to drive the upper end of the hanging rod to swing through the electric rebound device, so that the upper ends of the two hanging rods are close to each other. Since the middle part of the hanging rod is rotatably positioned and connected to the hook connecting piece, the lower ends of the two hanging rods will move away from each other under the action of the lever. In the process of moving away, since the aluminum ingot is placed on the ground or on the lifting platform and remains stationary, the aluminum ingot clamp and the hook holding the aluminum ingot are also in a fixed and stationary state. In this way, the lower end of the hanging rod will automatically detach from the hook during the movement, thereby automatically canceling the connection relationship between the hanging rod and the hook; when a new hook and aluminum ingot clamp needs to be installed, the hook to be replaced is directly placed between the two hanging rods, and the electric rebound device is controlled to make the upper ends of the two hanging rods move away from each other, and the lower ends of the two hanging rods are reset and approach each other under the action of the lever, thereby automatically hanging and connecting with the hooks, and different bundles of aluminum ingots can be hoisted.

[0007] Therefore, this solution allows for automatic installation and removal of the hook and aluminum ingot clamp by directly controlling the electric rebound device. This eliminates the need for manual replacement of the aluminum ingot clamp, improving safety and adapting to the lifting of different bundles of aluminum ingots. Furthermore, during the process of hoisting the aluminum ingots, the electric rebound device limits the connection control of the upper end of the hanging rod, ensuring the stability of the connection between the lower end of the hanging rod and the hook during the process, thereby preventing the hook and aluminum ingot from falling off during the hoisting process and ensuring safety.

[0008] Preferably, as an improvement, the lower end of the hanging rod is provided with a hook bent between the two hanging rods, the hook includes a base and a hook body, the hook body is connected to the upper end of the base, and there is an angle between the hook body and the base, the hook is stuck in the angle and resists the base and the hook body at the same time.

[0009] Through the above solution, the hooking connection between the hook body and the bent hook is used to realize the hooking of the hook rod and the hook, so that the connection and removal of the hook can be realized more conveniently, and the disassembly and assembly of the hook and aluminum ingot clips of different specifications is more convenient.

[0010] Preferably, as an improvement, there are at least two hooks uniformly distributed in a circular array around the axis of the base.

[0011] Through the above scheme, at least two hooks can be connected to the bent hook of the hanging rod, which increases the connection points between the hanging rod and the hook, and the two hooks are evenly distributed, so that after the hanging rod is connected to the hook, the aluminum ingot clamp is subjected to uniform and stable force, thereby enabling the aluminum ingot to be lifted smoothly and ensuring safety during the lifting process.

[0012] Preferably, as an improvement, the hook body is in the shape of a cone with the bottom concave upward.

[0013] With the above solution, since the hook body is conical, different parts of the hook body can be connected to the hook on the hanging rod. In this way, when the hook and the hanging rod are hung, any part can be connected to the hanging rod, making the connection operation between the two more convenient.

[0014] Preferably, as an improvement, the electric rebound device includes an electric push rod and a swing arm, the swing arm is located between the electric push rod and the upper end of the hanging rod, the two ends of the swing arm are rotatably connected to the upper ends of the electric push rod and the hanging rod respectively, and a long hole extending laterally is provided in the middle of the swing arm, and a pin is fixed on the hook connecting piece, and the pin is arranged through the long hole.

[0015] Through the above solution, the swing arm is controlled by an electric push rod, so that the swing arm controls the automatic swing opening and closing of the hanging rod, thereby realizing the connection and removal of the hook and the aluminum ingot clamp, eliminating the need for manual replacement of the hook and the aluminum ingot clamp, and making it more convenient and safer to use. The design of the latch and the long hole ensures that when the swing arm swings, the latch slides in the long hole along the length of the long hole, allowing the swing arm to swing around the latch to adapt to the swing of the hanging rod, avoiding obstruction or jamming of the hanging rod. At the same time, the latch also serves to position the swing arm.

[0016] Preferably, as an improvement, a fixed sleeve is fixed on the hook connector, a sliding shaft is slidably provided on the fixed sleeve, a spring is connected between the sliding shaft and the fixed sleeve, a rocker arm is provided between the lower end of the hanging rod and the sliding shaft, and both ends of the rocker arm are rotatably connected to the sliding shaft and the hanging rod respectively.

[0017] Through the above scheme, the fixed sleeve is used to install the sliding shaft. When the hook needs to be hung on the hanging rod, the upper end of the hanging rod swings outward, and the lower end of the hanging rod swings inward at the same time. The tightening force of the spring causes the sliding shaft and the swing rod to push the lower end of the hanging rod to swing, so that the curved hook on the hanging rod quickly enters the angle between the hook body and the base, and presses the curved hook tightly within the angle, making the connection between the hanging rod and the hook more stable.

[0018] Preferably, as an improvement, the hook and the aluminum ingot clamp are rotatably connected.

[0019] Through the above solution, the hook and the aluminum ingot clamp can rotate relative to each other, which makes it easier to clamp the aluminum ingot. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following is a detailed description of the present invention through specific embodiments, but the embodiments of the present invention are not limited thereto. Unless otherwise specified, the technical means used in the following embodiments are conventional means well known to those skilled in the art; the experimental methods used are conventional methods; and the materials and reagents used are all commercially available.

[0024] The figure marks in the drawings of the specification include: hook connector 1, hanging rod 2, electric push rod 3, swing arm 4, long hole 5, pin 6, hook 7, aluminum ingot clamp 8, bent hook 9, base 10, hook body 11, sliding shaft 12, fixed sleeve 13, and swing rod 14.

[0025] Example 1

[0026] The anti-falling quick-release hook in this embodiment is as follows: Figure 1 As shown, it includes a hook connector 1, a pair of oppositely arranged hanging rods 2 are provided on the hook connector 1, the middle part of the hanging rod 2 is rotatably set on the hook connector 1 through a positioning bolt or a rotating shaft, and the upper end of the hanging rod 2 is connected to an electric rebound device; the electric rebound device includes an electric push rod 3 and a swing arm 4, the swing arm 4 is located between the electric push rod 3 and the upper end of the hanging rod 2, the two ends of the swing arm 4 are respectively rotatably connected to the upper end of the hanging rod 2 and the electric push rod 3 through a positioning pin or a rotating shaft nail, and a transversely extending long hole 5 is provided in the middle of the swing arm 4, and a pin 6 is welded and fixed on the hook connector 1, and the pin 6 is set through the long hole 5.

[0027] The sling also includes a hook 7, the lower end of which is connected to an aluminum ingot clamp 8 for clamping aluminum ingots. In this embodiment, the lower end of the hook 7 is fixedly connected to the aluminum ingot clamp 8 by bolts, and multiple sets of hooks 7 and aluminum ingot clamps 8 are provided, each with a length suitable for clamping different bundles of aluminum ingots. The upper end of the hook 7 is inserted between the two hanging rods 2 and simultaneously connected to the lower ends of the two hanging rods 2. Specifically, the lower ends of the hanging rods 2 are provided with a hook 9 that bends toward the middle of the two hanging rods 2. The hook 7 includes a base 10 and a hook body 11. The hook body 11 is integrally formed and connected to the upper end of the base 10, and there is an angle between the hook body 11 and the base 10. The hook 9 is inserted into the angle and abuts against both the base 10 and the hook body 11. In this embodiment, there are at least two hook bodies 11 evenly distributed in a circular array around the axis of the base 10. This embodiment uses two hook bodies 11 as an example to illustrate the specific implementation process.

[0028] Combine Figure 2 As shown, a fixed sleeve 13 is fixed on the hook connector 1, a sliding shaft 12 is slidably provided on the fixed sleeve 13, a spring is connected between the sliding shaft 12 and the fixed sleeve 13, and the spring in this embodiment is a compression spring, which is located between the sliding shaft 12 and the fixed sleeve 13, and a rocker arm 14 is provided between the lower end of the hanging rod 2 and the sliding shaft 12, and the two ends of the rocker arm 14 are respectively connected to the sliding shaft 12 and the hanging rod 2 through a rotating shaft. During the specific implementation of this embodiment, when the hook 7 is hung for hoisting the aluminum ingot, the hook 7 is placed below the gap between the two hanging rods 2, and then the electronically controlled electric push rod 3 works, the electric push rod 3 contracts, and the two swing arms 4 move away from each other. During the movement of the swing arm 4, it swings around the pin 6 and pulls the upper end of the hanging rod 2 outward. The hanging rod 2 swings around the fixed point in the middle of itself, and the lower ends of the two hanging rods 2 move closer to each other under the action of the lever, so that the bent hook 9 is stuck in the angle between the base 10 and the hook body 11. The bent hook 9 stuck in the angle is against the base 10 on one side and the hook body 11 on the other side. At this time, the hanging between the hanging rod 2 and the hook 7 is completed, and the sling can be used for hoisting aluminum ingots.

[0029] When the hook 7 and the aluminum ingot clamp 8 need to be replaced, the electric push rod 3 is controlled to extend so that the two swing arms 4 move toward each other. The swing arms 4 squeeze the upper ends of the hanging rods 2 inward, so that the upper ends of the two hanging rods 2 are close to each other, and the lower ends of the two hanging rods 2 are away from each other. At this time, the bent hook 9 at the lower end of the hanging rod 2 is disengaged from between the base 10 and the hook body 11, and the hanging rod 2 is separated from the hook 7. In this way, the group of hooks 7 and the aluminum ingot clamp 8 are removed from the hanging rod 2, and then according to the aforementioned hanging process of the hook 7, a new hook 7 and aluminum ingot clamp 8 are re-hung on the hanging rod 2.

[0030] During the process of attaching and detaching the hook 7, the sliding shaft 12 controls the movement of the hanging rod 2 via the swing rod 14. When the hook 7 needs to be attached to the hanging rod 2, the upper end of the hanging rod 2 swings outward while the lower end of the hanging rod 2 swings inward. The spring's tightening force causes the sliding shaft 12 and the swing rod 14 to push the lower end of the hanging rod 2 inward, thereby allowing the curved hook 9 on the hanging rod 2 to quickly enter the angle between the hook body 11 and the base 10 and press the curved hook 9 into the angle, making the connection between the hanging rod 2 and the hook 7 more stable. The provision of the swing rod 14 makes the movement between the hanging rod 2 and the sliding shaft 12 more compatible, preventing the sliding shaft 12 from jamming the hanging rod 2.

[0031] Example 2

[0032] The difference between this embodiment and embodiment 1 is that Figure 3 As shown, the hook body 11 in this embodiment is in a conical shape with the bottom concave upward.

[0033] With the hook body 11 having such a structure, when connecting the hook body 11 and the curved hook 9, any part of the hook body 11 can be connected to the curved hook 9 on the hanging rod 2, thereby making the connection operation between the two more convenient.

[0034] Example 3

[0035] The difference between this embodiment and the aforementioned embodiment is that the hook 7 and the aluminum ingot clamp 8 in this embodiment are rotationally connected, and the specific rotational connection method is a mature existing technology, such as connection through a bearing, which will not be described here.

[0036] This connection method allows the hook 7 and the aluminum ingot clamp 8 to rotate relative to each other, which makes it easier to clamp the aluminum ingot.

[0037] The above description is merely an embodiment of the present invention, and the commonly known specific technical solutions and / or features of the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be considered as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed in this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
