It is divided into steel wire rope electric hoist and ring chain electric hoist. Whether it is a steel wire rope electric hoist or a ring chain electric hoist, it generally uses an independent control handle to realize the lifting of the chain or the steel wire rope by pressing the button, which is relatively inconvenient to control.

Its control handle can realize suspension control, which is no longer a simple button control, and the control is relatively simpler.

[0004] This patent application combines button operation and suspension control to control the electric hoist, which changes the traditional pure button control mode of the easy-to-operate handle. Although the operation is a little simpler, it only uses suspension control for the lifting and lowering actions of the electric hoist, and other actions still use button operation.

[0005] The Chinese utility model patent application with the authorization announcement number CN114955910B discloses an electric hoist electric control handle. The worker slides the handle up and down to drive the magnetic block to slide up and down, which causes the change of the magnetic field and the change of the voltage signal.

These are existing components and are not the improvement point of the present utility model, so they will not be described again. The improvement point of the present utility model will be described in detail below:

[0049] In order to realize the single-handed operation of the user, two cylindrical handles are arranged, one is operated by hand, and the other is operated by the thumb. The two cylindrical handles are a first cylindrical handle 13 and a second cylindrical handle 14, which are sleeved on the connecting rod 12, the first cylindrical handle 13 is above the second cylindrical handle 14, and the first cylindrical handle 13 and the second cylindrical handle 14 are rotatably sleeved on the connecting rod 12 and can slide up and down on the connecting rod 12. Through such 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 hold the second cylindrical handle 14 with the palm and four fingers, and operate the second cylindrical handle 14 to rotate inward, rotate outward, slide up and slide down, and operate the first cylindrical handle 13 with the thumb, and the first cylindrical handle 13 can be operated to rotate inward, rotate outward, slide up and slide down. Thus, the operation purpose of eight actions of one hand is realized. The eight actions need to be transmitted to the controller to generate eight control commands to control the corresponding executing mechanism to execute the control action of the handle, so the first rocker 15 and the second rocker 16 are installed on the connecting rod 12, the rocker holes 17 are arranged on the first cylindrical handle 13 and the second cylindrical handle 14, and the rocker arms 18 of the first rocker 15 and the second rocker 16 are inserted into the rocker holes 17 of the first cylindrical handle 13 and the second cylindrical handle 14. When the user controls the first cylindrical handle 13 and the second cylindrical handle 14, the first rocker 15 and the second rocker 16 will execute corresponding actions, and at this time the first rocker 15 and the second rocker 16 will send the corresponding action signals to the controller 11 through wired or wireless mode.

[0052] The control commands preset according to the action signal source and the action signal type are as follows:

[0053]

[0054]

In this way, the lifting command control of the electric hoist, the forward and backward movement command of the cart, and the left and right movement command of the trolley can be executed. The driving structure can also be a switch for suspension operation, so that the opening and closing control command of the handle suspension can be realized. The driving structure can also be a switch for suspension operation, so that the opening and closing control command of the handle suspension can be realized. The driving structure can also be a gear selection switch of the electric hoist, such as slow speed, after the slow speed action is started, the electric hoist is in slow speed gear, and the electric hoist is in slow speed action for accurate installation and alignment.

Through the elastic force of the second up-down reset elastic strip, the up-down reset of the second cylindrical handle is realized.

[0059] In order to realize the circumferential rotation reset of the second cylindrical handle 14, a second rotation reset elastic strip 1004 is arranged on the connecting rod 12, the second rotation reset elastic strip 1004 penetrates through the connecting rod 12, and the two ends of the connecting rod 12 are inserted into the second cylindrical handle 14. Through the elastic force of the second rotation reset elastic strip, the circumferential rotation reset of the second cylindrical handle is realized.

[0066] The rocker hole 17 of the second cylindrical body 140 is a horn hole, the inside is large and the outside is small, so that the rocker arm 18 of the second rocker sensor is inserted.

[0067] In the embodiment, the first and second cylindrical handles 13 and 14 need corresponding reset mechanisms to reset to the initial position after the operation of the above eight actions, and the specific structure of the reset mechanisms is not limited as long as the reset action can be achieved. The first and second cylindrical handles 13 and 14 are respectively connected with a reset mechanism to reset to the initial position after the up and down sliding and the inward and outward rotation of the first and second cylindrical handles 13 and 14.

[0068] Since the first and second cylindrical handles 13 and 14 are provided with the rocker hole and the first and second through holes, in order to prevent dust from entering from these holes and affecting the operation of the first and second rocker sensors 15 and 16 and the reset mechanisms, dustproof design is needed for these places, specifically:

[0069] The upper end of the first cylindrical handle 13 extends into the shell 10 through the through hole, and the rocker hole 18 provided on the upper end of the first cylindrical handle 13 is protected by the shell 10, which can effectively prevent dust from entering the rocker hole 18 and affecting the sensitivity of the first rocker sensor.

[0071] The dust cover is made of silica gel or rubber material.

[0072] The controller in the embodiment is the controller of the existing handle, which is a prior art and will not be described here.

[0073] Embodiment 2

[0074] In the embodiment, the user only needs to apply a force to the handle or the weight to control the lifting action of the electric hoist. In order to achieve the suspension control of the easy-to-operate handle, the following structure is designed:

[0075] A weight sensor 1006 is connected to the connecting rod 12 in the housing 10, and is used to detect the weight of the hook-hung heavy object. The weight sensor 1006 is connected to the controller 11, and the controller 11 is connected to the operation panel 1007, which is provided with a zero-reset button.

[0076] The weight sensor 1006 sends the detected heavy object weight information to the controller 11, which sends the weight information to the operation panel 1007 after receiving the weight information. The operation panel 1007 visually displays the weight information, and an alarm is triggered when the weight information of the heavy object exceeds the defined weight. When suspension control is needed, the user operates the zero-reset button of the operation panel. The controller receives the zero-reset operation command and resets the weight information of the heavy object to 0, which is displayed on the operation panel. In combination with Embodiment 1, the user holds the second cylindrical handle, rotates the second cylindrical handle outward, and the second gyro sensor receives the signal of the outward rotation of the second cylindrical handle and sends it to the controller. The controller generates a control command after receiving the signal, and opens the suspension. At this time, the easy-to-operate handle is in a suspended state. The user applies a force to the heavy object, and the weight sensor 1006 detects the force and sends a weight data to the controller 11. The controller determines whether the weight data is positive or negative after receiving the weight data. If it is positive, a control command is sent to control the electric hoist to move downward. If it is negative, the electric hoist is controlled to move upward, realizing the suspension control of the electric hoist. The user only needs to apply a small force to the heavy object to realize the up-down action control of the electric hoist, which is simple and convenient to operate.

[0077] Embodiment 3

[0078] This embodiment needs to realize the follow-up control of the easy-to-operate handle. The user pulls the handle, and the cart and trolley move, so that the easy-to-operate handle does not tilt and is in a vertical state, achieving the purpose of follow-up.

[0079] In order to realize the follow-up function of the electric handle, the following technical scheme is adopted:

[0080] A gyroscope sensor 8 and a controller 11 are installed on the handle body 1. The controller here can be a separate controller, or can share a controller with Embodiments 1 and 2. The gyroscope sensor is used to detect the inclination of the handle body, generate an inclination signal according to the detected inclination, and send the inclination signal to the controller.

[0081] The controller includes a signal receiving module, a signal processing module, and an inclination correction module.

[0082] The signal receiving module is used to receive the inclination signal sent by the gyroscope sensor and send the inclination signal to the signal processing module.

[0083] The signal processing module is configured to process the received tilt signal, analyze the tilt direction and the tilt angle, and send the analyzed tilt direction and the tilt angle to the tilt correction module.

[0084] The tilt correction module generates a control command according to the received tilt direction and the tilt angle, controls the movement of the large carriage and the small carriage in the tilt direction until the tilt angle is the same as the tilt angle of the initial position of the gyroscope sensor.

[0085] The tilt angle of the initial position of the gyroscope sensor refers to the tilt angle of the gyroscope sensor when the handle body is perpendicular to the ground. At this time, the gyroscope sensor is also perpendicular to the ground, and the tilt angle is 90°.

[0086] The controller and the gyroscope sensor are installed in the shell, and the controller and the gyroscope sensor are connected in communication by wired or wireless mode.

[0087] As shown in Figure 11 The initial position of the easy-to-operate handle is perpendicular to the ground, and after the user pulls the easy-to-operate handle forward, the easy-to-operate handle will tilt forward. At this time, the easy-to-operate handle is no longer perpendicular to the ground, but tilts forward on the ground. In the figure, the easy-to-operate handle is in the initial position when it is perpendicular, and the easy-to-operate handle is in the state after being pulled forward after tilting. Since the gyroscope sensor 8 is installed in the easy-to-operate handle, the gyroscope sensor 8 will also tilt with the easy-to-operate handle at this time. Once the gyroscope sensor 8 tilts, a forward tilt signal will be generated and sent to the controller. After the controller receives the tilt signal, a control command is generated according to the tilt signal to control the forward movement of the large carriage until the easy-to-operate 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 forward movement of the large carriage.

[0088] As shown in Figure 12 The initial position of the easy-to-operate handle is perpendicular to the ground, and after the user pulls the easy-to-operate handle forward, the easy-to-operate handle will tilt forward. At this time, the easy-to-operate handle is no longer perpendicular to the ground, but tilts forward on the ground. In the figure, the easy-to-operate handle is in the initial position when it is perpendicular, and the easy-to-operate handle is in the state after being pulled forward after tilting. Since the gyroscope sensor 8 is installed in the easy-to-operate handle, the gyroscope sensor 8 will also tilt with the easy-to-operate handle at this time. Once the gyroscope sensor 8 tilts, a forward tilt signal will be generated and sent to the controller. After the controller receives the tilt signal, a control command is generated according to the tilt signal to control the forward movement of the large carriage until the easy-to-operate 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 forward movement of the large carriage.

[0089] AsFigure 13 As shown, the easy-to-operate handle is initially perpendicular to the ground. When the user pulls the handle to the right, it tilts to the right, no longer perpendicular to the ground but tilted to the right. The diagram shows the handle in its initial position when it is perpendicular, and the tilted position after being pulled to the right. Since a gyroscope sensor 8 is installed inside the handle, it will also tilt with the handle. Once the gyroscope sensor 8 tilts, it generates a tilt signal to the right and sends it to the controller. Upon receiving the tilt signal, the controller generates a control command to move the cart to the right until the handle is no longer tilted and is perpendicular to the ground. At this point, the gyroscope sensor 8 can no longer detect the tilt signal, and the controller stops controlling the cart's rightward movement.

[0090] like Figure 14 As shown, the easy-to-operate handle is initially perpendicular to the ground. When the user pulls the handle to the left, it tilts to the left, no longer perpendicular to the ground but tilted to the left. The diagram shows the handle in its initial position when it is perpendicular, and the tilted position after being pulled to the left. Since a gyroscope sensor 8 is installed inside the handle, it will also tilt with the handle. Once the gyroscope sensor 8 tilts, it generates a tilt signal to the left and sends it to the controller. Upon receiving the tilt signal, the controller generates a control command to move the cart to the left until the handle is no longer tilted and is perpendicular to the ground. At this point, the gyroscope sensor 8 can no longer detect the tilt signal, and the controller stops controlling the cart to move to the left.

[0091] Of course, users may also pull the electric hoist handle in two directions at the same time, such as the front right, front left, rear right, and rear left. In this case, simply follow the above steps to control the corresponding trolley and carriage to move in the corresponding direction until the gyroscope sensor 8 can no longer detect the tilt signal. At this time, the handle body is perpendicular to the ground.

[0092] The above solution enables the easy-to-operate handle to move in the corresponding direction when tilted, so that the easy-to-operate handle moves in the direction the user pulls.

[0093] The gyroscope sensor 8 can be equipped with a three-dimensional tilt-compensated electronic geological compass module. The specific model is Maike Sensing HCM360B.

[0094] In order to avoid the handle follow-up caused by the user operation, the embodiment is installed on the bottom of the shell laser protection sensor, the laser protection sensor detects the user's hand on the first cylindrical handle and the second cylindrical handle, and then sends the follow-up command to the controller, and the controller receives the follow-up command and the tilt signal to control the movement of the cart and the trolley.
