Description

Technical Field

[0001] This utility model relates to a hook release device, specifically an electric remote-controlled hook release device, belonging to the field of hook technology. Background Technology

[0002] Hooks are the most commonly used lifting devices in lifting machinery. They are used to suspend heavy objects and to lift, move, and perform other operations on them. They are widely used in various scenarios that require lifting operations, such as factories, mines, ports, and construction. Currently, in order to eliminate the safety hazards that exist in the process of manually unlocking hooks, an electric remote control hook release device is usually installed on the hook to lock and unlock it.

[0003] However, most existing electric remote control unhooking devices have various problems. For example, in an electric remote control unhooking device disclosed in announcement number CN205953356U, although it drives a DC motor driven by a battery to rotate the rotary opener and realize remote control and automatic unhooking, it is safer, more convenient to use and simplifies the workflow compared to the traditional bottom-opening hook. However, in this technical solution and most current technical solutions, the hooks mostly adopt a bottom-opening design and lock the claws with the help of a locking structure driven by an electric remote control motor.

[0004] In related technologies, bottom-opening hooks have obvious drawbacks. On the one hand, during the lifting process, if a sudden vibration, shaking, or abnormal shaking caused by equipment failure occurs, the object being lifted will easily come loose from the opening if the external force exceeds the bearing capacity of the locking structure. On the other hand, after long-term use, the locking structure of bottom-opening hooks is prone to wear, corrosion, and other factors, which reduces the reliability of the locking. Moreover, when lifting objects with irregular shapes and unstable centers of gravity, the lateral force generated by the object on the locking structure during the swinging process can also easily cause the locking structure to fail, leading to hook disengagement. Utility Model Content

[0005] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, the purpose of this utility model is to solve the aforementioned shortcomings of existing technologies by proposing an electric remote-controlled unhooking device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electric remote-controlled unhooking device includes a support base, a hoisting plate, a connecting seat, a lifting claw, and a locking assembly. The hoisting plate is fixed on the support base, the connecting seat is rotatably connected to one side of the bottom of the hoisting plate, the lifting claw is fixed on the connecting seat, and the locking assembly is disposed between the support base and the hoisting plate.

[0008] The locking assembly includes a shaft, a linkage plate, a buckle, an electro-hydraulic push rod, and a reset assembly. The shaft is rotatably connected to the hoisting plate, the linkage plate is fixed to the shaft, the buckle is fixed to one end of the linkage plate, the fixed part of the electro-hydraulic push rod is rotatably connected to the other end of the linkage plate, the telescopic part of the electro-hydraulic push rod is rotatably connected to the support seat, and the reset assembly is disposed between the connecting seat and the linkage plate.

[0009] As a further embodiment of this utility model: the reset assembly includes a first reset rod, a second reset rod, and a mounting rod. One end of the first reset rod is provided with a cavity, and one end of the second reset rod is slidably engaged in the cavity. The two mounting rods are coaxially rotatably connected to the other ends of the first reset rod and the second reset rod, respectively, and the mounting rods are rotatably connected to the connecting seat and the linkage plate radially.

[0010] As a further embodiment of this utility model: a reset spring is provided in the cavity of the first reset rod, one end of the reset spring is fixed to the first reset rod, and the other end is fixed to the second reset rod.

[0011] As a further embodiment of this utility model: the inner wall of the cavity of the first reset rod and the outer wall of the first reset rod are both provided with threads, and the first reset rod and the second reset rod are connected by threads.

[0012] As a further improvement of this utility model: a remote control module is fixed on the support, and the remote control module is electrically connected to the electric hydraulic push rod.

[0013] As a further improvement of this utility model, at least two sets of reset components are provided, and the two sets of reset components are symmetrically arranged on both sides of the connector.

[0014] The beneficial effects of this utility model are:

[0015] In this invention, the lifting claw is designed with an upward-flipping structure, and the linkage plate is rotated by the extension and retraction of the electro-hydraulic push rod. This allows the buckle to quickly engage, lock, and disengage with the lifting claw. The reset component enables the lifting claw to move synchronously with the rotation of the linkage plate, achieving full automation and eliminating the need for manual assistance. The upward-flipping claw structure changes the traditional downward-opening design. After the lifting claw flips upward and closes, the opening faces upward, which reduces the risk of the load coming off due to gravity, shaking, or accidental collision from a physical structure perspective. Compared with the ordinary electric control locking structure, the buckle locking method driven by the electro-hydraulic push rod has a more stable output force and a greater locking force, which can firmly fix the lifting claw in the closed position. Even under complex working conditions and vibration or impact, it can maintain reliable locking, greatly reducing safety hazards.

[0016] In terms of ease of operation, the upward-flipping structure, combined with the electric hydraulic push rod drive, allows the lifting claw to be flipped, opened, closed, and locked via remote control, eliminating the need for close-range manual operation. This is especially suitable for lifting operations at heights, in dangerous or confined spaces, reducing the risks associated with manual intervention and improving work efficiency. At the same time, the controllable response speed of the hydraulic drive enables smooth opening and closing and precise locking of the lifting claw, avoiding the jamming or incomplete locking problems that may occur with mechanical locking.

[0017] From an adaptability perspective, the opening angle and closing range of the upward-flipping claw can be designed according to requirements, and can adapt to heavy objects of different sizes and shapes. The hydraulically driven buckle lock has a strong load capacity and can cope with lifting operations of various weights, enhancing the applicability of the unhooking device in complex working conditions.

[0018] In addition, this structural design can reduce frictional wear between the claws and the load and rigging. When the claws are flipped up to close, the contact between the claws and the buckle is more uniform, and the pressure distribution of the hydraulic locking is reasonable, which can reduce local wear, extend the service life of the equipment, and reduce maintenance costs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1, as Figures 1 to 4As shown, an electric remote-controlled unhooking device includes a support base 1, a hoisting plate 2, a connecting seat 3, a lifting claw 4, and a locking component 5. The hoisting plate 2 is fixed on the support base 1, the connecting seat 3 is rotatably connected to one side of the bottom of the hoisting plate 2, the lifting claw 4 is fixed on the connecting seat 3, and the locking component 5 is disposed between the support base 1 and the hoisting plate 2.

[0026] The locking assembly 5 includes a shaft 51, a linkage plate 52, a buckle 53, an electro-hydraulic push rod 54, and a reset assembly. The shaft 51 is rotatably connected to the hoisting plate 2, the linkage plate 52 is fixed to the shaft 51, the buckle 53 is fixed to one end of the linkage plate 52, the fixed part of the electro-hydraulic push rod 54 is rotatably connected to the other end of the linkage plate 52, the telescopic part of the electro-hydraulic push rod 54 is rotatably connected to the support seat 1, and the reset assembly is disposed between the connecting seat 3 and the linkage plate 52.

[0027] The reset assembly includes a first reset rod 55, a second reset rod 56, and a mounting rod 57. One end of the first reset rod 55 is provided with a cavity, and one end of the second reset rod 56 is slidably engaged in the cavity. The two mounting rods 57 are coaxially rotatably connected to the other ends of the first reset rod 55 and the second reset rod 56, respectively. The mounting rods 57 are rotatably connected to the connecting seat 3 and the linkage plate 52 radially, respectively. A reset spring 58 is provided in the cavity of the first reset rod 55. One end of the reset spring 58 is fixed to the first reset rod 55, and the other end is fixed to the second reset rod 56.

[0028] In this invention, the lifting claw 4 is designed with an upward-flipping structure, and the linkage plate 52 is rotated by the telescopic drive of the electric hydraulic push rod 54. This allows the buckle 53 to quickly engage, lock, and disengage with the lifting claw 4. The reset component enables the lifting claw 4 to move synchronously with the rotation of the linkage plate 52, achieving full automation and eliminating the need for manual assistance. The upward-flipping claw structure changes the traditional downward-opening design. After the lifting claw 4 flips upward and closes, the opening faces upward, which reduces the risk of the heavy object disengaging due to gravity, shaking, or accidental collision from a physical structure perspective. Compared with the ordinary electric control locking structure, the buckle locking method driven by the electric hydraulic push rod 54 has a more stable output force and a greater locking force, which can firmly fix the lifting claw in the closed position. Even under complex working conditions and vibration or impact, it can maintain reliable locking and significantly reduce safety hazards.

[0029] In terms of ease of operation, the upward-flipping structure, combined with the electric hydraulic push rod 54, allows the lifting claw 4 to be flipped, opened, closed, and locked via remote control, eliminating the need for close-range manual operation. This is especially suitable for lifting operations at heights, in dangerous or confined spaces, reducing the risks associated with manual intervention and improving work efficiency. At the same time, the hydraulic drive has a controllable response speed, enabling the lifting claw 4 to open and close smoothly and lock precisely, avoiding the jamming or incomplete locking problems that may occur with mechanical locking.

[0030] From an adaptability perspective, the opening angle and closing range of the upward-flipping claw can be designed according to requirements, and can adapt to heavy objects of different sizes and shapes. The hydraulically driven buckle lock has a strong load capacity and can cope with lifting operations of various weights, enhancing the applicability of the unhooking device in complex working conditions.

[0031] In addition, this structural design can reduce frictional wear between the lifting claw and the load and rigging. When the lifting claw 4 is closed upwards, the contact between the lifting claw 4 and the buckle 53 is more uniform, and the pressure distribution of the hydraulic locking is reasonable, which can reduce local wear, extend the service life of the equipment, and reduce maintenance costs.

[0032] Example 2, as Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0033] The inner wall of the cavity of the first reset rod 55 and the outer wall of the first reset rod 55 are both provided with threads. The first reset rod 55 and the second reset rod 56 are connected by threads. The threaded connection makes the distance between the first reset rod 55 and the second reset rod 56 adjustable, thereby making the compression deformation and elastic force of the reset spring 58 adjustable.

[0034] A remote control module 6 is fixed on the support 1. The remote control module 6 is electrically connected to the electric hydraulic push rod 54. The electric hydraulic push rod 54 can be remotely driven through the remote control module 6.

[0035] At least two sets of reset components are provided, and the two sets of reset components are symmetrically arranged on both sides of the connecting seat 3. The symmetrically arranged reset components make the force between the connecting seat 3 and the linkage plate 52 more uniform, and also enable the lifting claw 4 to reset quickly.

[0036] When using this unhooking device, if it is necessary to lock the hoisted material, the electric hydraulic push rod 54 is extended by remote control. At this time, the linkage plate 52 rotates, and the connecting seat 3 and the lifting claw 4 are flipped up as a whole through the first reset rod 55 and the second reset rod 56 until the buckle 53 is locked with the lifting claw 4. When it is necessary to unload the material, the electric hydraulic push rod 54 is retracted by remote control. At this time, the linkage plate 52 rotates and drives the buckle 53 to separate from the lifting claw 4. After separation, due to the gravity of the material, the gravity overcomes the elastic force of the reset spring 58, causing the lifting claw 4 to flip and unload the material. At the same time, the first reset rod 55 and the second reset rod 56 slide relative to each other.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
