[0041] The above three aspects of the design will be described in detail below in combination with the drawings and specific embodiments:

[0042] Embodiment 1

[0043] The technical problem to be solved by the present embodiment is how to realize single-handed operation of the handle by the user and realize operation control of eight actions.

[0044] To solve the above technical problem, the technical scheme adopted by the present embodiment is:

[0045] An electric hoist handle comprises a handle body 1, the upper end of the handle body 1 is connected with a chain 3 of an electric hoist 7 through a joint 2, and the lower end of the handle body 1 is connected with a hook 4 through a joint. The chain 3 is wound around the electric hoist 7, the electric hoist 7 is installed on a trolley 6, the trolley 6 is installed on a cart 5, the electric hoist 7 moves left and right with the trolley 6, and the trolley 6 moves forward and backward with the cart 5.

[0046] The handle body 1 comprises an outer shell 10, a controller 11 arranged in the outer shell 10, and a connecting rod 12 vertically fixed in the outer shell 10, the upper and lower ends of the outer shell 10 are provided with through holes, the two ends of the connecting rod 12 extend out of the outer shell 10 through the through holes, the upper end of the connecting rod 12 extending out of the outer shell 10 is connected with the chain 3 through the joint 2, and the lower end of the connecting rod 12 is connected with the hook 4 through the joint 2. The outer shell 10 is provided with an emergency stop button, an operation panel 1007, an air valve switch, a 485 or CN wired control plug, a servo clamp switch control plug, a data port, an external servo control switch signal plug and the like, and these components are connected with the controller. These are existing components and are not the improvement points of the present utility model, and therefore will not be described in detail, and the improvement points of the present utility model will be described in detail below:

[0047] 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.

[0048] After receiving the action signal, the controller 11 first confirms whether the action signal is sent by the first rocker 15 or the second rocker 16, and then confirms whether the action signal type is an upslide signal, a downslide signal, an inward rotation signal or an outward rotation signal. After confirming the action signal source and the action signal type, the corresponding control command is selected according to the action signal source, the action signal type and the preset control command, and the control command is sent to the corresponding executing mechanism to execute the corresponding action.

[0049] The control commands preset in the controller can be preset in the following manner, of course, they can also be exchanged with each other or other control commands can be 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.

[0050] The control commands preset according to the action signal source and the action signal type are as follows:

[0051]

[0052] According to different control commands, the actuator can be various execution structures, mainly the driving mechanism of the electric hoist, the cart and the trolley, such as the motor driving the electric hoist to lift, the motor driving the cart to move forward and backward, and the motor driving 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 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 operation is started, the electric hoist is in slow speed gear, and the electric hoist is in slow speed action for accurate installation and alignment.

[0053] The specific structure of the first cylindrical handle 13 is:

[0054] It includes a first cylindrical body 130, a roller 131 is arranged on the first cylindrical body 130, the roller 131 is fixed on the first cylindrical body 130, an upper end of the first cylindrical body 130 is provided with a rocker hole 17, the rocker hole 17 penetrates the first cylindrical body 130 radially, and a lower end of the first cylindrical body 130 is provided with a first through hole 132, the first through hole 132 penetrates the first cylindrical body 130 radially.

[0055] The rocker hole 17 of the first cylindrical body 130 is a horn hole, the inside is large and the outside is small, so that the rocker arm 18 of the first rocker sensor is inserted.

[0056] The specific structure of the second cylindrical handle 14 is:

[0057] It includes a second cylindrical body 140, annular grooves 141 are arranged at the upper end and the lower end of the second cylindrical body 140, a rocker hole 17 is arranged in the annular groove 141 at the upper end, the rocker hole 17 penetrates the second cylindrical body 140 radially, a second through hole 142 is arranged in the annular groove 141 at the lower end, the second through hole 142 penetrates the second cylindrical body 140 radially, and a finger groove 143 is arranged at the middle part 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.

[0058] 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.

[0059] 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 mechanism 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 for resetting 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.

[0060] In order to facilitate the resetting of the first and second cylindrical handles 13 and 14, the embodiment provides a reset mechanism, which includes a reset hole 19 and a reset member 100. The reset hole 19 is a tapered hole, and the reset 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 reset member 100 is a steel ball spring wave ball top wire, and the model is preferably M8*16. The specific structure includes a stud 1001, a steel ball 1002 and a reset spring 1003. The stud 1001 is provided with a groove 1004 at the top end, the reset spring 1003 is installed in the groove 1004, and the steel ball 1002 is connected to the reset spring 1003. When the reset spring 1003 is in a free state, the steel ball 1002 is partially located in the groove 1004 and partially protrudes out of the groove 1004. The threads of the stud 1001 are matched with the threads of the first and second through holes 132 and 142. The stud 1001 is screwed into the first and second through holes 132 and 142, the top surface of the steel ball 1002 is in contact with the lowest point of the reset hole 19, and the reset spring 1003 is in a free state.

[0061] The resetting principle and process of the reset mechanism are as follows: when the first and second cylindrical handles 13 and 14 are not operated, the top surface of the steel ball 1002 is in contact with the lowest point of the reset hole 19, and the reset spring 1003 is in a free state. After the first and second cylindrical handles 13 and 14 are up and down slid and inward and outward rotated, since the reset hole 16 is a tapered hole, the stud 1001 will slide in the tapered hole and no longer be at the lowest point. The reset spring 1003 will be compressed, and the reset spring 1003 will be in a compressed state. After the user no longer operates the first and second cylindrical handles 13 and 14, the stud 1001 will be outwardly and inwardly pushed by the reset spring 1003. Since the stud 1001 is threadedly connected with the first and second through holes 132 and 142 and cannot move outwardly, the steel ball 1002 will slide to the lowest point under the action of the reset spring, which will reset the stud 1001 and drive the first and second cylindrical handles 13 and 14 to reset to the initial position.

[0062] The reset mechanism is used to realize the reset of the first and second cylindrical handles 13 and 14 after the up-down sliding and circumferential rotation, and the reset member and the reset hole are matched to limit the up-down sliding of the first and second cylindrical handles 13 and 14 to prevent damage caused by over sliding.

[0063] The first and second rocker sensors 15 and 16 are both rocker potentiometers. The rocker arm of the rocker potentiometer itself also has a reset function, and the self-reset of the rocker arm can also play a certain reset role. However, the reset force is small, and in order to avoid unsuccessful reset, the reset mechanism is added. The reset mechanism and the self-reset of the first and second rocker sensors 15 and 16 can fully ensure that the first and second cylindrical handles 13 and 14 can be successfully reset.

[0064] Since the first and second cylindrical handles 13 and 14 are provided with the rocker arm hole and the first and second through holes, in order to prevent dust from entering these holes and affecting the working of the first and second rocker sensors 15 and 16 and the reset mechanism, dustproof design is needed for these places, which is specifically as follows:

[0065] 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 and affecting the sensitivity of the first rocker sensor.

[0066] A dust cover 1005 is arranged on the connecting rod 12 between the first and second cylindrical handles 13 and 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, and the lower end of the dust cover 1005 is buckled on the upper end of the second cylindrical body 14 to cover the rocker arm hole 18 arranged on the second cylindrical body 14. The dust cover 1005 is also arranged on the connecting rod 12 below the second cylindrical handle 14 and buckled on the lower end of the second cylindrical body 14 to cover the second through hole 142. The dust cover protects the rocker arm hole, the first through hole and the second through hole of the second cylindrical body 14 from dust, prevents dust from entering the rocker arm hole of the second cylindrical body 14 to affect the sensing sensitivity of the second rocker sensor, and prevents dust from entering the first and second through holes to affect the reset of the first and second cylindrical handles.

[0067] The dust cover is made of silica gel or rubber material.

[0068] The controller in the embodiment is the controller of the existing handle, which is a prior art and will not be described here.

[0069] Embodiment 2

[0070] The embodiment is to realize the suspension control of the electric hoist handle, and 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 realize the suspension control of the electric hoist handle, the following structure is designed:

[0071] The weight sensor 1006 is connected to the connecting rod 12 in the shell 10, and the weight sensor 1006 is used to detect the weight of the hook hanging weight, and the weight sensor 1006 is connected with the controller 11, and the controller 11 is connected with the operation panel 1007, and the zero reset button is arranged on the operation panel 1007.

[0072] The weight sensor 1006 sends the detected weight information of the weight to the controller 11, and the controller 11 receives the weight information and sends it to the operation panel 1007, and the operation panel 1007 visually displays the weight information, and when the weight information of the weight exceeds the limited weight, an alarm will be given. When the suspension control is needed, the user operates the zero reset button of the operation panel, the controller receives the zero reset operation command, and the weight information of the weight is zeroed and displayed as 0 on the operation panel. According to 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 receives the signal and generates a control command to open the suspension. At this time, the electric hoist handle is in a suspended state, and the user applies a force to the weight. The weight sensor 1006 detects the force and generates a weight data, which is sent to the controller 11. The controller receives the weight data and determines whether the weight data is positive or negative. If it is positive, a control command is sent to control the electric hoist to move downward, and 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 weight to realize the up-down action control of the electric hoist, which is simple and convenient to operate.

[0073] Embodiment 3

[0074] The embodiment needs to realize the follow-up control of the electric hoist handle. The user pulls the handle, and the cart and the trolley will move, so that the electric hoist handle will not tilt and be in a vertical state, achieving the purpose of follow-up.

[0075] In order to realize the follow-up function of the electric handle, the following technical scheme is adopted:

[0076] The gyroscope sensor 8 and the controller 11 are installed on the handle body 1. The controller here can be a separate controller, or it 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, and send the inclination signal to the controller.

[0077] The controller includes a signal receiving module, a signal processing module, and a tilt correction module.

[0078] 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;

[0079] 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.

[0080] The tilt correction module generates control commands based on 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 gyroscope sensor.

[0081] The initial tilt angle 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, with a tilt angle of 90°.

[0082] The controller and gyroscope sensor are installed inside the housing, and the controller and gyroscope sensor communicate with each other via wired or wireless means.

[0083] like Figure 12 As shown, the electric hoist handle is initially perpendicular to the ground. When the user pulls the handle forward, it tilts forward, no longer perpendicular to the ground but tilted towards it. The diagram shows the handle in its initial vertical position and tilted position after being pulled forward. Since a gyroscope sensor 8 is installed inside the handle, it tilts along with the handle. This tilt generates a forward tilt signal, which is sent to the controller. Upon receiving the tilt signal, the controller generates a control command to move the hoist forward until the handle is no longer tilted and is perpendicular to the ground. At this point, the gyroscope sensor 8 no longer detects the tilt signal, and the controller stops controlling the hoist's forward movement.

[0084] like Figure 13As shown, the electric hoist handle is initially perpendicular to the ground. When the user pulls the handle backward, it tilts backward, no longer perpendicular to the ground but tilted. The diagram shows the handle in its initial vertical position and tilted position after being pulled backward. Since a gyroscope sensor 8 is installed inside the handle, it tilts along with the handle. This tilt generates a backward tilt signal, which is sent to the controller. Upon receiving the tilt signal, the controller generates a control command to move the hoist backward until the handle is no longer tilted but perpendicular to the ground. At this point, the gyroscope sensor 8 no longer detects the tilt signal, and the controller stops controlling the hoist's backward movement.

[0085] like Figure 14 As shown, the electric hoist handle is initially perpendicular to the ground. When the user pulls the handle to the right, it tilts to the right, no longer perpendicular but tilted to the right. The diagram shows the handle in its initial vertical position and tilted position after being pulled to the right. Since a gyroscope sensor 8 is installed inside the handle, it also tilts with the handle. This tilt generates a rightward tilt signal, which is sent to the controller. Upon receiving the tilt signal, the controller generates a control command to move the trolley to the right until the handle is no longer tilted and is perpendicular to the ground. At this point, the gyroscope sensor 8 no longer detects the tilt signal, and the controller stops controlling the trolley's rightward movement.

[0086] like Figure 15 As shown, the electric hoist 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 tilted, 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 trolley 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 trolley to move to the left.

[0087] Of course, the user can also pull the electric hoist handle in two directions at the same time, such as pulling the electric hoist handle in front right, front left, back right, and back left directions, at which time only the above steps are needed to control the corresponding car and trolley to move in the corresponding direction until the tilt signal detected by the gyroscope sensor 8 is not detected, at which time the handle body is perpendicular to the ground.

[0088] Through the above scheme, the electric hoist handle can be controlled to move in the corresponding direction as soon as it is tilted, so as to achieve the electric hoist handle following the user pulling direction.

[0089] The gyroscope sensor 8 can be a three-dimensional tilt compensation electronic geological compass module. The specific model is Maike sensor HCM360B.

[0090] In order to avoid the handle following caused by the user operation, the laser protection sensor is installed on the bottom of the shell in the embodiment, the laser protection sensor detects the user's hand on the first and second cylindrical handles, and then sends the following command to the controller, and the controller receives the following command and the tilt signal to control the car and trolley to move.

[0091] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
