Description

Technical Field

[0001] This invention relates to the field of hoisting equipment technology, and in particular to a remote-controlled crane hook, control method, and crane. Background Technology

[0002] Crane hooks are equipped with anti-detachment mechanisms to prevent accidental detachment of lifted loads, which could cause damage to goods and injuries. However, traditional remote-controlled crane hooks rely solely on gravity to close the hook opening. In actual use, factors such as the external environment, lifting speed, and load weight can cause the wire rope to swing, making it easy for the load to detach and fall, resulting in damage. This type of anti-detachment mechanism is prone to failure.

[0003] To address this, patent number 202420575129.4 discloses a crane hook anti-disengagement structure. As the hook body slowly rises, the weight of the load presses down on a baffle. At this point, one end of the baffle, which is in close contact with the hook body, moves downward, opening the hook body and allowing the load to be hooked onto it. The baffle then returns to its original position. Alternatively, the baffle can be manually pushed to hook the load onto the hook body, with one end of the baffle pressing against the hook body, reducing the possibility of the load disengaging. The opening mechanism allows the baffle to be opened when manual opening is inconvenient, facilitating unloading and reducing the risk of damage from falling loads and minimizing personnel injury. When unloading requires opening the baffle, a motor drives a reel to rotate, winding a connecting rope. This rope pulls the baffle, opening it. Reversing the motor releases the rope from the reel, and the baffle returns to its original position via a spring.

[0004] However, whether the baffle of the crane hook anti-disengagement structure is open and in place requires construction personnel to get close and observe. The control and adjustment of the baffle also requires close operation and control, which wastes manpower and time. In addition, human negligence can sometimes occur, which can easily lead to personal injury or death.

[0005] Therefore, it is necessary to propose a remote-controlled crane hook, control method, and crane to solve the above problems. This would address the issues of whether the baffle of the traditional crane hook anti-disengagement structure is open and in place, requiring construction personnel to be close to observe, and the control and adjustment of the baffle also requires close operation, which wastes manpower and time, is prone to human negligence, and can easily lead to personnel injuries. Summary of the Invention

[0006] This invention provides a remote control crane hook, control method, and crane, solving the problems of traditional crane hook anti-disengagement structures where the baffle needs to be opened and in place, requiring construction personnel to be close to observe, and the control and adjustment of the baffle also requires close operation, which wastes manpower and time, is prone to human negligence, and can easily lead to personnel injury or death.

[0007] The technical problem solved by this invention is achieved by the following technical solution: A remote-controlled crane hook includes a hook body, a control device, a housing, a baffle, a motor, a reduction gear set, a position sensor, and a wireless transceiver, wherein the motor, the position sensor, and the wireless transceiver are electrically connected to the control device. The outer shell is fixed to the hook body, the baffle shaft end rotates relative to the outer shell, and the motor is connected to the baffle shaft end through a reduction gear set; The position sensor is used to sense the position of the baffle. The wireless transceiver is used to transmit the baffle position signal to the remote control terminal and to receive the baffle position command sent by the remote control terminal. The control device is used to control the motor to rotate according to the baffle position command, thereby controlling the baffle to open or close the hook body.

[0008] Furthermore, it also includes an image recognition device disposed on the housing and electrically connected to the control device. The image recognition device is used to identify the actual baffle outline and compare it with a preset closed outline. When the difference between the actual baffle outline and the preset closed outline is less than a set value, the baffle position is determined to be closed. When the difference between the actual baffle outline and the preset closed outline is greater than or equal to the set value, the baffle position is determined to be open. The image recognition device wirelessly transmits the identified baffle position signal to the remote control terminal for display.

[0009] Furthermore, it also includes an electric lead screw assembly fixed to the outer casing, and a push rod driven by the electric lead screw assembly to extend and retract. The electric lead screw assembly is electrically connected to the control device. When the baffle closes the hook body and the push rod is in contact with the baffle, the baffle is locked by the push rod. The electric lead screw assembly includes an electric lead screw, a slider driven by the electric lead screw to move back and forth, a spring connected to the slider at one end, and the other end of the spring connected to the push rod.

[0010] Furthermore, a pressure sensor is provided between the push rod and the spring, and the pressure sensor is electrically connected to the control device.

[0011] A remote control method for crane hook control, characterized by comprising the following steps: a. The position sensor detects the position of the baffle and wirelessly transmits the baffle position signal to the remote control terminal for display; b. The remote control terminal obtains the baffle position command issued by the user and wirelessly transmits the baffle position command signal to the control device; c. The control device controls the baffle to rotate to the baffle position corresponding to the command signal.

[0012] Furthermore, it also includes the following steps: The image recognition device identifies the actual outline of the baffle and compares it with a preset closed outline. When the difference between the actual baffle outline and the preset closed outline is less than a set value, the baffle is determined to be in a closed state. When the difference between the actual baffle outline and the preset closed outline is greater than or equal to the set value, the baffle is determined to be in an open state. The image recognition device wirelessly transmits the identified baffle position signal to a remote control terminal for display.

[0013] Furthermore, it also includes a push rod for locking or unlocking the baffle, and further includes the following steps: The image recognition device identifies the actual position of the push rod and compares it with the preset locking position. When the difference between the actual push rod position and the preset locking position is less than the set value, the push rod position is determined to be in a locked state. When the difference between the actual push rod position and the preset locking position is greater than or equal to the set value, the push rod position is determined to be in an unlocked state. The image recognition device wirelessly transmits the identified push rod position signal to the remote control terminal for display. The remote control terminal obtains the push rod position command issued by the user and wirelessly transmits the push rod position command signal to the control device; The control device controls the push rod to move to the push plate position corresponding to the push rod position command signal.

[0014] Furthermore, the hook body is also equipped with a push rod for locking or unlocking the baffle, and the specific implementation steps are as follows: The pressure sensor detects the actual thrust applied by the spring and wirelessly transmits the actual thrust data to the remote control terminal for display; the remote control terminal obtains the locking force command issued by the user and wirelessly transmits the locking force command signal to the control device; the control device controls the spring to apply a thrust to the pressure sensor corresponding to the locking force command signal.

[0015] Furthermore, the hook body is also equipped with a push rod for locking or unlocking the baffle, a pressure sensor for sensing the pushing force on the push rod, and a spring for applying the pushing force to the push rod. The specific implementation steps are as follows: The image recognition device identifies the actual outline of the goods and identifies the corresponding goods type according to the goods type database. Each goods type has a preset corresponding locking force value. The control device controls the spring to apply a thrust corresponding to the locking force value to the pressure sensor. The pressure sensor senses the actual thrust applied by the spring and wirelessly transmits the actual thrust data to the remote control terminal for display.

[0016] A crane includes the aforementioned remote-controlled crane hook, or a method of applying the aforementioned remote-controlled crane hook.

[0017] The beneficial effects of this invention are: This invention comprises a control device, a housing, a baffle, a motor, a reduction gear set, a position sensor, and a wireless transceiver. The motor, position sensor, and wireless transceiver are electrically connected to the control device. The housing is fixed to the hook body, and the baffle's rotating shaft rotates relative to the housing. The motor and the baffle's rotating shaft are connected via a reduction gear set. The position sensor senses the baffle's position. The wireless transceiver transmits the baffle's position signal to a remote control terminal and receives baffle position commands from the remote control terminal. The control device controls the motor's rotation based on the baffle position commands, thereby controlling the baffle to open or close the hook body. This allows the user to detect the baffle's position via the remote control terminal, determining whether the hook body is open or closed, and to control the baffle's position as needed. This solves the problems of traditional crane hook anti-disengagement structures where checking the baffle's opening and positioning requires close observation by construction personnel, and the control and adjustment of the baffle also requires close operation, wasting manpower and time, increasing the risk of human error and injury.

[0037] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] See Figures 1 to 9 A remote-controlled crane hook includes a hook body 100, and also includes a control device 1, a housing 2, a baffle 3, a motor 4, a reduction gear set 5, a position sensor 6, and a wireless transceiver 7. The motor 4, the position sensor 6, and the wireless transceiver 7 are electrically connected to the control device 1. The outer shell 2 is fixed on the hook body 100, the rotating end of the baffle 3 rotates relative to the outer shell 2, and the motor 4 is connected to the rotating end of the baffle 3 through a reduction gear set 5. The position sensor 6 is used to sense the position of the baffle 3; The wireless transceiver 7 is used to transmit the baffle position signal to the remote control terminal and to receive the baffle position command sent by the remote control terminal. The control device 1 is used to control the motor 4 to rotate according to the baffle position command, thereby controlling the baffle 3 to open or close the hook body 100.

[0039] In use, the position sensor 6 senses the position of the baffle 3. If the baffle is sensed to be open, the wireless transceiver 7 transmits the open baffle position signal to the remote control terminal. If the user wants to keep it open, no operation is required. If the user wants to close the baffle 3, they can issue a command to the remote control terminal to close the baffle, which is then sent to the wireless transceiver 7. The control device 1 uses the command to close the baffle to control the motor 4 to rotate, thereby controlling the baffle 3 to close the hook body 100. This is convenient, quick, and can intelligently determine the hook body 100, eliminating human error and making it very safe to use.

[0040] In this way, users can detect the position of the baffle 3 through the remote control terminal, thereby determining whether the hook body 100 is in the open or closed state. They can also control the position of the baffle as needed through the remote control terminal, thereby realizing the remote control of the opening or closing of the hook body 100. This solves the problems of traditional crane hook anti-disengagement structures, such as the need for construction personnel to get close to observe whether the baffle is open and in place, the need for close operation to control the baffle, the waste of manpower and time, the possibility of human negligence, and the risk of personal injury.

[0041] Preferably, the position sensor 6 is a limit switch, and the baffle 3 is provided with a protrusion. When the baffle 3 is rotated to the closed state, the protrusion touches the position sensor 6, and the position of the baffle 3 can be sensed.

[0042] It also includes an image recognition device 8 mounted on the housing 2 and electrically connected to the control device 1. The image recognition device 8 is used to identify the actual baffle outline of the baffle 3 and compare it with a preset closed outline. When the difference between the actual baffle outline and the preset closed outline is less than a set value, the baffle position is determined to be closed; when the difference between the actual baffle outline and the preset closed outline is greater than or equal to the set value, the baffle position is determined to be open. The image recognition device 8 wirelessly transmits the identified baffle position signal to the remote control terminal for display. The crane hook can determine the baffle position through image recognition by the image recognition device 8, providing a second judgment measure when the position sensor 6 fails, further reducing the risk of misjudgment.

[0043] It also includes an electric lead screw assembly 9 fixed to the outer casing 2, and a push rod 10 driven by the electric lead screw assembly 9 to extend and retract. The electric lead screw assembly 9 is electrically connected to the control device 1. When the baffle 3 closes the hook body 100 and the push rod 10 is in contact with the baffle 3, the baffle 3 is locked by the push rod 10. The electric lead screw assembly 9 includes an electric lead screw 90, a slider 91 driven by the electric lead screw 90 to move back and forth, and a spring 92 connected at one end to the slider 91. The other end of the spring 92 is connected to the push rod 10. The push rod 10 can further limit the baffle 3 when the baffle 3 is in the closed state, thereby locking the baffle 3 and achieving double anti-detachment protection. When the push rod 10 is in contact with the baffle 3, the electric lead screw 90 continues to push the slider 91, causing the spring 92 to squeeze the push rod 10, achieving different locking forces. Users can select the locking force according to their needs and control the adjustment through a remote control terminal. For example, if the goods are important, heavy, dangerous, prone to swaying or tilting, or require less repetitive operation, the locking force can be increased. Conversely, if the risk factor is low, the weight is light, or repetitive operation is required, the locking force can be decreased.

[0044] A pressure sensor 11 is provided between the push rod 10 and the spring 92, and the pressure sensor 11 is electrically connected to the control device 1. The pressure sensor 11 can sense the locking force and transmit the locking force to the remote control terminal through the wireless transceiver 7, so that the user can remotely monitor the locking force in real time.

[0045] Example 1, see Figure 10 A remote control method for crane hook control, characterized by comprising the following steps: a. The position sensor detects the position of the baffle and wirelessly transmits the baffle position signal to the remote control terminal for display; b. The remote control terminal obtains the baffle position command issued by the user and wirelessly transmits the baffle position command signal to the control device; c. The control device controls the baffle to rotate to the baffle position corresponding to the command signal.

[0046] In use, the position sensor 6 senses the position of the baffle 3. If the baffle is in an open position, the wireless transceiver 7 transmits the open baffle position signal to the remote control terminal. At this time, if the user wants to keep it open, no operation is required. If the user wants to close the baffle 3, they can issue a baffle position command to the remote control terminal and send it to the wireless transceiver 7. The control device 1 uses the baffle position command to control the motor 4 to rotate, thereby controlling the baffle 3 to close the hook body 100.

[0047] Example 2, see Figure 11 Unlike Embodiment 1, this embodiment also includes the following steps: The image recognition device identifies the actual outline of the baffle and compares it with a preset closed outline. When the difference between the actual baffle outline and the preset closed outline is less than a set value, the baffle is determined to be in a closed state; when the difference is greater than or equal to the set value, the baffle is determined to be in an open state. The image recognition device wirelessly transmits the identified baffle position signal to a remote control terminal for display. The crane hook can determine the baffle position through image recognition by the image recognition device 8, providing a second judgment measure when the position sensor 6 fails, further reducing the risk of misjudgment.

[0048] Example 3, see Figure 12 Unlike embodiments one and two, the hook body is also equipped with a push rod for locking or unlocking the baffle. The specific implementation steps are as follows: The image recognition device identifies the actual position of the push rod and compares it with the preset locking position. When the difference between the actual push rod position and the preset locking position is less than the set value, the push rod position is determined to be in a locked state. When the difference between the actual push rod position and the preset locking position is greater than or equal to the set value, the push rod position is determined to be in an unlocked state. The image recognition device wirelessly transmits the identified push rod position signal to the remote control terminal for display. The remote control terminal obtains the push rod position command issued by the user and wirelessly transmits the push rod position command signal to the control device; The control device controls the push rod to move to the push plate position corresponding to the push rod position command signal.

[0049] The push rod 10 can further limit the baffle 3 when the baffle 3 is in the closed state, thereby locking the baffle 3 and achieving double anti-derailment protection. The crane hook can determine the position of the push rod by image recognition through the image recognition device 8, and send the position of the push rod to the remote control terminal through the wireless transceiver 7, so that the user can remotely monitor the locking position in real time.

[0050] Example 4, see Figure 13 Unlike embodiments one to three, the hook body is also equipped with a push rod for locking or unlocking the baffle, a pressure sensor for sensing the pushing force on the push rod, and a spring for applying the pushing force to the push rod. The specific implementation steps are as follows: The pressure sensor detects the actual thrust applied by the spring and wirelessly transmits the actual thrust data to the remote control terminal for display; the remote control terminal obtains the locking force command issued by the user and wirelessly transmits the locking force command signal to the control device; the control device controls the spring to apply a thrust to the pressure sensor corresponding to the locking force command signal.

[0051] With push rod 10 in contact with baffle 3, electric lead screw 90 continues to push slider 91, causing spring 92 to compress push rod 10, achieving different locking forces. Pressure sensor 11 can sense the locking force and transmit it to a remote control terminal via wireless transceiver 7, allowing users to monitor the locking force remotely in real time. Users can select the locking force according to their needs and adjust it via the remote control terminal. For example, if the goods are important, heavy, dangerous, prone to swaying or tilting, or require less repetitive operation, the locking force can be increased. Conversely, if the risk factor is low, the weight is light, or repetitive operation is required, the locking force can be decreased.

[0052] Example 5, see Figure 14 Unlike embodiments one to four, this embodiment also includes a push rod for locking or unlocking the baffle, a pressure sensor for sensing the pushing force on the push rod, and a spring for applying the pushing force to the push rod, and further includes the following steps: The image recognition device identifies the actual outline of the goods and determines the corresponding goods type based on a goods type database. Each goods type has a preset corresponding locking force value. The control device controls the spring to apply a thrust corresponding to the locking force value to the pressure sensor. The pressure sensor senses the actual thrust applied by the spring and wirelessly transmits the actual thrust data to the remote control terminal for display. The crane hook can identify the goods type through image recognition by the image recognition device 8, thereby intelligently adjusting the required locking force value. The pressure sensor 11 can sense the locking force and transmit it to the remote control terminal through the wireless transceiver 7. Users can remotely monitor the locking force in real time and adjust the locking force value as needed.

[0053] A crane includes the aforementioned remote-controlled crane hook, or the method of applying the aforementioned remote-controlled crane hook. This type of crane can solve the problems of traditional crane hook anti-disengagement structures, such as the need for construction personnel to be close to observe whether the baffle is open and in place, the need for close operation and control of the baffle, wasting manpower and time, the possibility of human negligence, and the risk of personal injury.
