Description

Technical Field

[0001] The invention relates to a lifting device, in particular to a handle controlled by an electric hoist. Background Art

[0002] Electric hoist is a special lifting equipment installed on overhead crane and gantry crane. It is divided into wire rope electric hoist and chain electric hoist. Both wire rope electric hoist and chain electric hoist generally use independent control handles to achieve the lifting and lowering of chains or wire ropes by pressing buttons, which is inconvenient to control.

[0003] The Chinese invention patent application with application number and publication number CN111943070A discloses an intelligent electric hoist with a suspension control structure, whose control handle can realize suspension control, and is no longer a simple button control, and the control is relatively simpler.

[0004] This patent application is a combination of button operation and suspension control to control the electric hoist, which changes the traditional pure button control method of the electric hoist handle. Although the operation is simpler, only the rising and falling actions of the electric hoist are controlled by suspension, and other actions are still controlled by button operation.

[0005] The Chinese invention patent application with the authorization announcement number CN114955910B discloses an electric control handle for an electric hoist. When a worker slides the handle up and down, the magnetic block slides up and down, which in turn causes a change in the magnetic field, which generates a change in the voltage signal. The speed of the motor is controlled by the change in the size of the voltage signal, thereby achieving control of the electric hoist. The sliding handle up and down in the patent application can only control the rotation of the motor to achieve the control of the rising and falling actions of the electric hoist, while other actions are still operated by buttons.

DETAILED DESCRIPTION

[0041] The electric hoist handle provided by the present invention is improved in design from the following three aspects:

[0042] First, users can complete the operation control of eight actions with one hand, and no button operation is used, making the operation simple and convenient.

[0043] Secondly, with the use of a suspended handle design, users only need to apply a force to the weight or the handle to control the lifting and lowering action of the electric hoist, which simplifies the operation of the handle.

[0044] Thirdly, the handle is designed to follow the movement. The user can control the movement of the cart and the trolley by pulling the handle, ensuring that the handle moves with the user's operation and automatically corrects when the handle is tilted, so that the handle is perpendicular to the ground.

[0045] The designs of the above three aspects are described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0046] Example 1

[0047] The technical problem to be solved by this embodiment is: how to enable the user to operate the handle with one hand to realize the operation control of eight actions.

[0048] In order to solve the above technical problems, the technical solution adopted in this embodiment is:

[0049] An electric hoist handle comprises a handle body 1, the upper end of the handle body 1 is connected to a chain 3 of an electric hoist 7 through a joint 2, and the lower end of the handle body 1 is connected to a hook 4 through a joint. The chain 3 is wound around the electric hoist 7, the electric hoist 7 is mounted on a trolley 6, the trolley 6 is mounted on a large vehicle 5, the electric hoist 7 moves left and right with the trolley 6, and the trolley 6 moves forward and backward with the large vehicle 5.

[0050] The handle body 1 includes a housing 10, a controller 11 disposed in the housing 10, and a connecting rod 12 vertically fixed in the housing 10. Through holes are disposed at the upper and lower ends of the housing 10. Both ends of the connecting rod 12 extend out of the housing 10 through the through holes. The upper end of the connecting rod 12 extending out of the housing 10 is connected to the chain 3 through the joint 2, and the lower end of the connecting rod 12 is connected to the hook 4 through the joint 2. The housing 10 is provided with an emergency stop button, an operation panel 1007, a gas valve switch, a 485 or CN wired control plug, a servo fixture switch control plug, a data port, an external servo control switch signal plug and other components. These components are all connected to the controller. These are existing components and are not the improvement points of the present invention. Therefore, they will not be repeated. The improvement points of the present invention are described in detail below:

[0051] In order to realize the one-hand operation of the user, two cylindrical handles are provided, one cylindrical handle is operated by holding with the hand, and the other cylindrical handle is operated by flipping with the thumb. The two cylindrical handles are respectively the first cylindrical handle 13 and the second cylindrical handle 14, the first cylindrical handle 13 and the second cylindrical handle 14 are respectively sleeved on the connecting rod 12, the first cylindrical handle 13 is located above the second cylindrical handle 14, the first cylindrical handle 13 and the second cylindrical handle 14 are rotatably sleeved on the connecting rod 12, and the first cylindrical handle 13 and the second cylindrical handle 14 can also slide up and down on the connecting rod 12. Through such a design, the first cylindrical handle 13 and the second cylindrical handle 14 can be operated to rotate inward, rotate outward, slide up and slide down around the connecting rod 12, the user can operate the second cylindrical handle 14 to rotate inward, rotate outward, slide up and slide down by holding the second cylindrical handle 14 with the palm and four fingers, and the first cylindrical handle 13 can be operated to rotate inward, rotate outward, slide up and slide down by flipping the first cylindrical handle 13 with the thumb, so that the first cylindrical handle 13 can be operated to rotate inward, rotate outward, slide up and slide down, so that the operation purpose of eight actions of one hand is realized. These eight actions need to be transmitted to the controller so that the controller generates eight control commands and controls the corresponding actuators to execute to realize the control actions of the handles. Therefore, the first rocker sensor 15 and the second rocker sensor 16 are also installed on the connecting rod 12, and the first cylindrical handle 13 and the second cylindrical handle 14 are provided with rocker arm holes 17. The rocker arms 18 of the first rocker sensor 15 and the second rocker sensor 16 are inserted into the rocker arm holes 17 of the first cylindrical handle 13 and the second cylindrical handle 14. In this way, when the user controls the first cylindrical handle 13 and the second cylindrical handle 14, the first rocker sensor 15 and the second rocker sensor 16 will be driven to perform corresponding actions. At this time, the first rocker sensor 15 and the second rocker sensor 16 will send the corresponding action signals to the controller 11 through wired or wireless means.

[0052] After receiving the action signal, the controller 11 first confirms the source of the action signal, whether it is the action signal sent by the first shake sensor 15 or the second shake sensor 16, and then confirms the type of the action signal, whether it is an upward sliding signal, a downward sliding signal, an inward rotation signal or an outward rotation signal. After confirming the source of the action signal and the type of the action signal, the controller 11 generates a corresponding control command according to the source of the action signal, the type of the action signal and the preset control command, and sends the control command to the corresponding actuator to perform the corresponding action.

[0053] The control commands preset in the controller can be preset in the following manner. Of course, other control commands can also be interchanged or preset, as long as they can correspond to the eight actions generated by operating the first cylindrical handle 13 and the second cylindrical handle 14.

[0054] The preset control commands according to the action signal source and action signal type are as follows:

[0055]

[0056]

[0057] Depending on the control command, the actuator can be a variety of execution structures, mainly the driving mechanisms of the electric hoist, trolley and cart, such as the motor that drives the electric hoist to rise and fall, the motor that drives the trolley to move forward and backward, and the motor that drives the trolley to move left and right. In this way, the lifting command control of the electric hoist, the forward and backward movement command of the trolley, and the left and right movement command of the trolley can be executed. The driving structure can also be a suspended operation switch, so that the opening and closing control commands of the handle suspension can be realized. The driving structure can also be an electric hoist gear selection switch. For example, after the slow opening action is started, the electric hoist is in the slow gear, and the electric hoist is in slow action for precise installation and alignment.

[0058] The specific structure of the first cylindrical handle 13 is:

[0059] It includes a first cylindrical body 130, on which a roller 131 is provided, and the roller 131 is fixed to the first cylindrical body 130. A rocker hole 17 is provided at the upper end of the first cylindrical body 130, and the rocker hole 17 radially penetrates the first cylindrical body 130. A first through hole 132 is provided at the lower end of the first cylindrical body 130, and the first through hole 132 radially penetrates the first cylindrical body 130.

[0060] The rocker arm hole 17 of the first cylindrical body 130 is a trumpet hole, with a large end inside and a small end outside, for the rocker arm 18 of the first rocker sensor to be inserted.

[0061] The specific structure of the second cylindrical handle 14 is:

[0062] The second cylindrical body 140 includes an annular groove 141 at both the upper and lower ends of the second cylindrical body 140, a rocker hole 17 is arranged in the annular groove 141 at the upper end, and the rocker hole 17 radially penetrates the second cylindrical body 140, a second through hole 142 is arranged in the annular groove 141 at the lower end, and the second through hole 142 radially penetrates the second cylindrical body 140, and a finger groove 143 is arranged in the middle of the second cylindrical body 140. The function of the finger groove is to facilitate the user to hold the second cylindrical body 140 so as to operate the second cylindrical handle 14.

[0063] The rocker arm hole 17 of the second cylindrical body 140 is a trumpet hole, with a large end inside and a small end outside, so that the rocker arm 18 of the second rocker sensor can be inserted.

[0064] In this embodiment, the first cylindrical handle 13 and the second cylindrical handle 14 need to realize the above eight actions, and a corresponding reset mechanism is required to reset the first cylindrical handle 13 and the second cylindrical handle 14 to the initial position, and the specific structure of the reset mechanism is not limited, as long as the reset action can be realized. The first cylindrical handle 13 and the second cylindrical handle 14 are each connected to a reset mechanism for reset, and the first cylindrical handle 13 and the second cylindrical handle 14 are respectively reset to the initial position after sliding up, sliding down, rotating inward and rotating outward.

[0065] In order to facilitate the resetting of the first cylindrical handle 13 and the second cylindrical handle 14, the present embodiment provides a resetting mechanism, which includes a resetting hole 19 and a resetting member 100. The resetting hole 19 is a tapered hole, and the resetting hole 19 is arranged on the connecting rod 12. The first through hole 132 arranged on the first cylindrical handle 13 and the second through hole 142 arranged on the second cylindrical handle 14 are threaded holes. The resetting member 100 is a steel ball spring wave ball top screw, and the model is preferably M8*16. Its specific structure The stud 1001 includes a stud 1001, a steel ball 1002 and a reset spring 1003. A groove 1004 is provided at the top of the stud 1001. The reset spring 1003 is installed in the groove 1004. The steel ball 1002 is connected to the reset spring 1003. When the reset spring 1003 is in a free state, part of the steel ball 1002 is located in the groove 1004 and part of it protrudes out of the groove 1004. The thread of the stud 1001 is adapted to the thread of the first through hole 132 and the second through hole 142. The stud 1001 is screwed into the first through hole 132 and the second through hole 142. The top surface of the steel ball 1002 contacts the lowest point of the reset hole 19, and the reset spring 1003 is in a free state.

[0066] The reset principle and process of the reset mechanism are as follows: when the first cylindrical handle 13 and the second cylindrical handle 14 are not operated, the top surface of the steel ball 1002 contacts the lowest point of the reset hole 19, and the reset spring 1003 is in a free state. After the first cylindrical handle 13 and the second cylindrical handle 14 slide up, down, rotate inward and outward, since the reset hole 16 is a tapered hole, the stud 1001 will slide in the tapered hole and will no longer be at the lowest point, and the reset spring 1003 will be compressed. The reset spring 1003 is in a compressed state. In the retracted state, when the user no longer operates the first cylindrical handle 13 and the second cylindrical handle 14, the stud 1001 will be pushed outward by the reset spring 1003 and the steel ball 1002 will be pushed inward. Since the stud 1001 is threadedly connected to the first through hole 132 and the second through hole 142, it cannot move outward. At this time, the steel ball 1002 will be pushed to the lowest point under the action of the reset spring, thereby causing the stud 1001 to reset, and also driving the first cylindrical handle 13 and the second cylindrical handle 14 to reset to their initial positions.

[0067] The first cylindrical handle 13 and the second cylindrical handle 14 are reset after sliding up and down and rotating circumferentially through the reset mechanism. At the same time, the cooperation between the reset member and the reset hole can also play a limiting role to prevent the first cylindrical handle and the second cylindrical handle from sliding up and down excessively and causing damage.

[0068] The first rocker sensor 15 and the second rocker sensor 16 are both rocker potentiometers. The rocker arm of the rocker potentiometer also has a reset function, and the self-reset of the rocker arm can also play a certain reset role, but its reset force is small. In order to avoid unsuccessful reset, a reset mechanism is added. Through the reset function of the reset mechanism and the self-reset ability of the first rocker sensor 15 and the second rocker sensor 16, it can fully ensure that the first cylindrical handle 13 and the second cylindrical handle 14 can be reset successfully.

[0069] Since the first cylindrical handle 13 and the second cylindrical handle 14 are provided with a rocker hole and a first through hole and a second through hole, in order to prevent dust from entering through these holes and affecting the operation of the first rocker sensor 15, the second rocker sensor 16 and the reset mechanism, dustproof design is required for these places, specifically:

[0070] The upper end of the first cylindrical handle 13 extends into the shell 10 through the through hole, and the rocker arm hole 18 arranged at the upper end of the first cylindrical handle 13 is protected by the shell 10, which can effectively prevent dust from entering the rocker arm hole 18, thereby preventing dust from entering and affecting the sensitivity of the first rocker sensor.

[0071] A dust cover 1005 is provided on the connecting rod 12 between the first cylindrical handle 13 and the second cylindrical handle 14. The upper end of the dust cover 1005 is buckled on the lower end of the first cylindrical body 13 to cover the first through hole 132; the lower end of the dust cover 1005 is buckled on the upper end of the second cylindrical body 14 to cover the rocker hole 18 provided in the second cylindrical body 14; a dust cover 1005 is also provided on the connecting rod 12 below the second cylindrical handle 14. The dust cover 1005 is buckled on the lower end of the second cylindrical body 14 to cover the second through hole 142. The provision of the dust cover provides dust protection for the rocker hole, the first through hole and the second through hole of the second cylindrical body 14, preventing dust from entering the rocker hole of the second cylindrical body 14 to affect the sensitivity of the second rocker sensor, and entering the first through hole and the second through hole to affect the resetting of the first cylindrical handle and the second cylindrical handle.

[0072] The dust cover is made of silicone or rubber material.

[0073] The controller can be the controller used for the existing electric hoist handle. It is an existing structure and will not be described in detail here.

[0074] Example 2

[0075] This embodiment is to realize the suspension control of the electric hoist handle. The user only needs to apply a force to the handle or a heavy object to control the lifting action of the electric hoist. In order to realize the suspension control of the electric hoist handle, the following structure is designed:

[0076] A weight sensor 1006 is connected to the connecting rod 12 in the housing 10. The weight sensor 1006 is used to detect the weight of the weight hanging from the hook. The weight sensor 1006 is connected to the controller 11. The controller 11 is connected to the operation panel 1007. A reset button is provided on the operation panel 1007.

[0077] The weight sensor 1006 sends the detected weight information of the heavy object to the controller 11. After receiving the weight information, the controller 11 sends it to the operation panel 1007. The operation panel 1007 visually displays the weight information. When the weight information of the heavy object exceeds the specified weight, an alarm will be issued. When suspension control is required, the user operates the zeroing button on the operation panel. After receiving the zeroing operation command, the controller resets the weight information of the heavy object to zero and displays it as 0 on the operation panel. In combination with Example 1, the user holds the second cylindrical handle and rotates the second cylindrical handle outward. The second shake sensor receives the signal of the second cylindrical handle rotating outward and sends it to the controller. After receiving the signal, the controller generates a control command to turn on the suspension. At this time, the electric hoist handle is in a suspended state. The user applies a force to the heavy object. After the weight sensor 1006 detects this force, it generates a weight data and sends it to the controller 11. After receiving the weight data, the controller determines whether the weight data is positive or negative. If it is positive, a control command is issued to control the electric hoist to move downward. If it is negative, the electric hoist is controlled to move upward to realize the suspension control of the electric hoist. The user only needs to simply apply a very small force to the heavy object to realize the up and down movement control of the electric hoist. The operation is simple and convenient.

[0078] Example 3

[0079] This embodiment needs to realize the follow-up control of the electric hoist handle. When the user pulls the handle, the trolley and the cart will move, so that the electric hoist handle will not tilt and remain in a vertical state, thereby achieving the purpose of follow-up.

[0080] In order to realize the follow-up function of the electric handle, the following technical solutions are adopted:

[0081] A gyro sensor 8 and a controller 11 are mounted on the handle body 1. The controller here can be a separate controller or a controller shared by the first and second embodiments. The gyro sensor is used to detect the tilt of the handle body, generate a tilt signal when the tilt is detected, and send the tilt signal to the controller.

[0082] The controller includes a signal receiving module, a signal processing module and a tilt correction module.

[0083] The signal receiving module is used to receive the tilt signal sent by the gyroscope sensor and send the tilt signal to the signal processing module;

[0084] The signal processing module is used to process the received tilt signal, analyze the tilt direction and tilt angle, and send the analyzed tilt direction and tilt angle to the tilt correction module;

[0085] The tilt correction module generates a control command according to the received tilt direction and tilt angle, and controls the large vehicle and the small vehicle to move in the tilt direction until the tilt angle is the same as the tilt angle of the initial position of the gyro sensor.

[0086] The tilt angle of the gyro sensor's initial position refers to the tilt angle of the gyro sensor when the handle body is perpendicular to the ground. At this time, the gyro sensor is also perpendicular to the ground, and the tilt angle is 90°.

[0087] The controller and the gyro sensor are installed in the housing, and the controller and the gyro sensor are connected for communication via wired or wireless means.

[0088] like Fig.12 As shown, the initial position of the electric hoist handle is perpendicular to the ground. After the user pulls the electric hoist handle forward, the electric hoist handle will tilt forward. At this time, the electric hoist handle is no longer perpendicular to the ground, but tilted forward to the ground. The electric hoist handle in the figure is in the initial position when it is in a vertical state. The electric hoist handle is in the state after being pulled forward after tilting. Since a gyroscope sensor 8 is installed in the electric hoist handle, the gyroscope sensor 8 will also tilt with the electric hoist handle at this time. Once the gyroscope sensor 8 tilts, a tilt signal for tilting forward will be generated, and the tilt signal will be sent to the controller. After receiving the tilt signal, the controller generates a control command according to the tilt signal to control the trolley to move forward until the electric hoist handle is no longer tilted but perpendicular to the ground. At this time, the gyroscope sensor 8 cannot detect the tilt signal, and the controller no longer controls the trolley to move forward.

[0089] like Fig.13As shown, the initial position of the electric hoist handle is perpendicular to the ground. After the user pulls the electric hoist handle backward, the electric hoist handle will tilt backward. At this time, the electric hoist handle is no longer perpendicular to the ground, but tilted to the ground. The electric hoist handle in the figure is in the initial position when it is in a vertical state. The electric hoist handle is in the state after being pulled backward after tilting. Since a gyroscope sensor 8 is installed in the electric hoist handle, the gyroscope sensor 8 will also tilt with the electric hoist handle at this time. Once the gyroscope sensor 8 tilts, a tilt signal tilting backward will be generated, and the tilt signal will be sent to the controller. After receiving the tilt signal, the controller generates a control command according to the tilt signal to control the trolley to move backward until the electric hoist handle is no longer tilted but perpendicular to the ground. At this time, the gyroscope sensor 8 cannot detect the tilt signal, and the controller no longer controls the trolley to move backward.

[0090] like Fig.14 As shown, the electric hoist handle is initially perpendicular to the ground. After the user pulls the electric hoist handle to the right, the electric hoist handle will tilt to the right. At this time, the electric hoist handle is no longer perpendicular to the ground, but tilted to the right on the ground. The electric hoist handle in the figure is in the initial position when it is in a vertical state. The electric hoist handle is in the state after being pulled to the right after being tilted. Since a gyroscope sensor 8 is installed in the electric hoist handle, the gyroscope sensor 8 will also tilt with the electric hoist handle at this time. Once the gyroscope sensor 8 tilts, a tilt signal tilting to the right will be generated, and the tilt signal will be sent to the controller. After receiving the tilt signal, the controller generates a control command according to the tilt signal to control the trolley to move to the right until the electric hoist handle is no longer tilted but perpendicular to the ground. At this time, the gyroscope sensor 8 cannot detect the tilt signal, and the controller no longer controls the trolley to move to the right.

[0091] like Fig.15 As shown, the initial position of the electric hoist handle is perpendicular to the ground. After the user pulls the electric hoist handle to the left, the electric hoist handle will tilt to the left. At this time, the electric hoist handle is no longer perpendicular to the ground, but tilted to the left on the ground. The electric hoist handle in the figure is in the initial position when it is in a vertical state. The electric hoist handle is in the state after being pulled to the left after tilting. Since a gyroscope sensor 8 is installed in the electric hoist handle, the gyroscope sensor 8 will also tilt with the electric hoist handle at this time. Once the gyroscope sensor 8 tilts, a tilt signal tilting to the left will be generated, and the tilt signal will be sent to the controller. After receiving the tilt signal, the controller generates a control command according to the tilt signal to control the trolley to move to the left until the electric hoist handle is no longer tilted but perpendicular to the ground. At this time, the gyroscope sensor 8 cannot detect the tilt signal, and the controller no longer controls the trolley to move to the left.

[0092] Of course, the user may also pull the electric hoist handle in two directions at the same time, such as the front right side, front left side, rear right side, and rear left side. At this time, just follow the above steps to control the corresponding trolley and cart to move in the corresponding directions until the gyroscope sensor 8 detects no tilt signal, and the handle body is perpendicular to the ground.

[0093] Through the above scheme, once the handle of the electric hoist is tilted, the trolley and the cart will be controlled to move in the corresponding direction, so that the handle of the electric hoist moves in the direction in which the user pulls.

[0094] The gyroscope sensor 8 can use a three-dimensional tilt compensation electronic geological compass module, the specific model is Maike Sensor HCM360B.

[0095] In order to prevent the handles from following movement due to non-user operation, a laser protection sensor is installed on the bottom of the shell in this embodiment. The laser protection sensor will send a following command to the controller only after detecting that the user's hands are placed on the first cylindrical handle and the second cylindrical handle. The controller will control the movement of the large and small carts only after receiving the following command and the tilt signal.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
