[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] It should be noted that the directional words such as "upper" and "lower" mentioned below are defined based on the drawings in the specification.

[0053] The core of the present invention is to provide an auxiliary picking device for industrial vehicles, which is convenient for drivers to pick high-level goods without occupying driving space, while improving the safety of drivers, improving the efficiency of continuous picking, and increasing the practicality of industrial vehicles. Another core of the present invention is to provide a control method including the auxiliary picking device of the above industrial vehicle, which improves the safety of drivers and improves the efficiency of continuous picking.

[0054] Please refer to Figure 1 , Figure 2 and Figure 3 , an auxiliary picking device for an industrial vehicle, the industrial vehicle is provided with a frame 1, a control device, an accelerator, a fork lifting drive device, a buzzer, a warning light, an auxiliary picking device 2 and a detection device 4.

[0055] Specifically, a driving area 11, an operating area 12 and a fork lifting area 13 are sequentially provided on the frame 1. A control device is provided in the driving area 11. The control device is signal-connected with the accelerator, fork lifting drive device, buzzer and warning light of the industrial vehicle. The operating status of the accelerator, fork lifting drive device, buzzer and warning light is controlled by the control device. The auxiliary picking device 2 is flippably provided in the operating area 12. One end of the auxiliary picking device 2 is rotatably connected to the frame 1 of the driving area 11, driving the other end of the auxiliary picking device 2 to flip so as to overlap the positioning beam 3 of the frame 1 of the fork lifting area 13. The auxiliary picking device 2 is set to a flippable structure so that the auxiliary picking device 2 has a foldable function. When the auxiliary picking device 2 is needed, it is opened, and when it is not needed, it is folded to reduce the occupied space of the auxiliary picking device 2, and it is also convenient for the driver to pick high-rise goods, thereby improving the practicality of the industrial vehicle.

[0056] The detection device 4 is arranged on the positioning beam 3. When the detection device 4 detects that someone is standing on the auxiliary picking device 2, it sends a signal to the control device. The control device controls the accelerator and the fork lifting drive device to stop running, and controls the buzzer and the warning light to turn on. That is to say, when someone is standing on the auxiliary picking device 2, the detection device 4 is triggered, so that the detection device 4 sends a signal to the control device, and the accelerator and the fork lifting drive device are controlled by the control device to stop running to prevent the accelerator or the fork lifting drive device from accidentally moving or taking off and landing due to failure or misoperation of other people, thereby improving the safety of the picking personnel's operation. At the same time, the buzzer and the warning light are controlled to turn on to remind the driver and surrounding workers to pay attention and avoid safety problems.

[0057] The auxiliary picking device 2 is generally arranged in the driver's operating area 12. In order not to affect the driver's normal operation, the space occupied when folded should be as small as possible. The design needs to be relatively compact and simple. Considering the safety of the picking operation, it is necessary to cooperate with the control device to control the entire vehicle. When the detection device 4 detects that someone is standing on the auxiliary picking device 2, it enters the auxiliary picking mode, prohibits the vehicle's walking and lifting functions, and turns on the buzzer and warning lights to remind the driver and surrounding workers; considering the continuous picking operation, in order to avoid frequent opening and closing of the auxiliary picking device 2, it will only be triggered when someone is standing. The auxiliary picking device 2 will be closed after continuous picking operations, which can greatly improve the operation efficiency.

[0058] The auxiliary picking device of the industrial vehicle arranged in the above manner makes it convenient for the driver to pick goods at high levels, while not occupying precious driving space, thereby improving the safety of the driver and the efficiency of continuous picking.

[0059] Please refer to Figure 4 The detection device 4 includes a nylon block 41, a detection switch 42 and a spring 43. The nylon block 41 is movably arranged on the positioning beam 3. The top of the nylon block 41 is higher than the upper end surface of the positioning beam 3. The detection switch 42 is arranged on the positioning beam 3 and is located directly below the nylon block 41. The detection switch 42 is connected to the control device signal. The spring 43 is arranged on the outer periphery of the nylon block 41. The spring 43 is used to provide a pre-tightening force to move the nylon block 41 upward, so that the detection switch 42 will not be triggered when the nylon block 41 contacts the auxiliary picking device 2. The detection switch 42 will only be triggered when the operator stands on the auxiliary picking device 2.

[0060] It should be noted that when the auxiliary picking device 2 is opened, it can be pressed on the nylon block 41. The nylon block 41 provides a preload force to support the auxiliary picking device 2 upward under the action of the spring 43. At this time, the detection switch 42 will not be triggered. When a person stands on the auxiliary picking device 2, the gravity of the person overcomes the preload force of the spring 43, pressing the nylon block 41 downward to trigger the detection switch 42, so that the detection switch 42 sends a signal to the control device, which controls the accelerator and the fork lifting drive device to stop running to prevent the accelerator or the fork lifting drive device from accidentally moving or taking off and landing due to failure or misoperation by other people, thereby improving the safety of the picker's operation. At the same time, the buzzer and warning lights are controlled to turn on to alert the driver and surrounding workers to avoid safety problems.

[0061] Among them, the spring 43 is preferably a wave spring 43, referred to as a wave spring, which is an elastic element with several peaks and valleys on a thin metal ring. It is usually used in situations where the load and deformation are not large, and the spring 43 is required to have a small stiffness and an axial preload needs to be applied.

[0062] In the above case, the nylon block 41 is a cylindrical step structure, and the nylon block 41 includes an abutment portion and an extension portion that are coaxially arranged and interconnected. The diameter of the abutment portion is larger than the diameter of the extension portion. The end of the extension portion away from the abutment portion is provided with a long hole extending along its own diameter direction, and a removable limiter 44 is provided in the long hole.

[0063] It is understandable that by setting the nylon block 41 as a cylindrical step structure, it is convenient to install the nylon block 41 on the positioning beam 3, and by setting a limiter 44 on the extension part, the nylon block 41 is limited to prevent the nylon block 41 from detaching from the positioning beam 3.

[0064] Furthermore, the limiting member 44 is a cotter pin.

[0065] It should be noted that the stopper 44 is preferably a split pin for easy installation and removal. In practical applications, there is no restriction on the type of the stopper 44 as long as the above technical effect can be achieved.

[0066] In the above embodiment, the positioning beam 3 is a U-shaped beam, and the opening of the positioning beam 3 faces downward. The top plate of the positioning beam 3 is provided with a mounting hole for installing the nylon block 41. The positioning beam 3 is provided with a limit plate 5 for limiting the limit member 44. The limit plate 5 is provided with a through hole for installing the extension part. The limit member 44 is located below the limit plate 5. The positioning beam 3 is also provided with a mounting plate 6 for installing the detection switch 42. The mounting plate 6 is located below the limit plate 5.

[0067] It can be understood that the nylon block 41 and the detection switch 42 are both arranged on the positioning beam 3 to achieve effective fixation of the detection switch 42, and the nylon block 41 is effectively pre-tightened by the spring 43. After the nylon block 41 is installed, the lower end of the extension part extends to the bottom of the limit plate 5, and the nylon block 41 is limited to the positioning beam 3 by the limit member 44.

[0068] On the basis of the above embodiment, the spring 43 is sleeved on the outer periphery of the extension portion, and one end of the spring 43 abuts against the lower end surface of the abutting portion, and the other end of the spring 43 abuts against the upper end surface of the limiting plate 5 .

[0069] It should be noted that the spring 43 is arranged between the top plate of the positioning beam 3 and the limit plate 5, one end of the spring 43 abuts against the bottom of the abutment portion of the nylon block 41, and the other end abuts against the top of the limit plate 5, so that the spring 43 can be extended and retracted between the two to achieve pre-tightening of the nylon block 41.

[0070] In the above embodiment, two groups of the auxiliary picking device 2 and the detection device 4 are provided, and the auxiliary picking device 2 and the detection device 4 are provided in a one-to-one correspondence.

[0071] It can be understood that, in the present application, the auxiliary picking device 2 and the detection device 4 are each provided with two groups, and are arranged on both sides of the operating area 12 .

[0072] Please refer to Figure 5 The auxiliary picking device 2 includes a flip plate 21 and a pedal 22 arranged on the flip plate 21. One end of the flip plate 21 is rotatably connected to the frame 1 through a connecting component 23, driving the other end of the flip plate 21 to flip in a direction close to or away from the positioning beam 3.

[0073] It should be noted that the flip plate 21 is rotatably connected to the frame 1 through the connecting assembly 23 to achieve a foldable connection of the flip plate 21. When the pedal 22 is used, the flip plate 21 is opened, and when the pedal 22 is not used, the flip plate 21 is folded.

[0074] In the above situation, a magnet 7 is provided on the flip plate 21 and a positioning block 8 is provided on the vehicle frame 1. After the flip plate 21 is folded, the magnet 7 attracts the positioning block 8 tightly.

[0075] It is understandable that a raised positioning block 8 is provided on the frame 1, which allows the strong magnet 7 fixed on the flip plate 21 to suck the positioning block 8 to maintain the position, thereby preventing the auxiliary picking device 2 from accidentally opening when the vehicle is driven and bumped suddenly.

[0076] Among them, the position maintenance when closed can be achieved by other methods such as a lock, a gas spring 43, etc., and is not limited to the magnet 7 provided in the present application.

[0077] Please refer to Figure 6 The connecting assembly 23 includes a first fixing plate 231 and a second fixing plate 232, both of which are U-shaped plates, and the first fixing plate 231 and the second fixing plate 232 are combined into a rectangular box body, the first fixing plate 231 is arranged on the frame 1, and a positioning plate 233 is fixed on the first fixing plate 231, and the positioning plate 233 is an L-shaped plate, and a positioning hole is provided on the positioning plate 233, and the two end plates of the first fixing plate 231 are provided with through holes for installing the rotating shaft 234, and the two ends of the rotating shaft 234 are rotatably connected to the flip plate 21, and a torsion spring 235 is sleeved on the rotating shaft 234, one end of the torsion spring 235 is arranged in the limiting hole, and the other end of the torsion spring 235 extends out of the box body and abuts against the bottom of the flip plate 21, and the torsion spring 235 is used to provide a pre-tightening force to rotate the flip plate 21 toward the positioning block 8.

[0078] It should be noted that the torsion spring 235 provides a preload force to flip the flip plate 21 and the pedal 22 upward, so as to overcome part of the gravity of the flip plate 21 and the pedal 22, so that when the flip plate 21 and the pedal 22 are opened, the pedal 22 will slowly open to the bottom to avoid a strong collision with the nylon block 41. At the same time, the spring 43 of the detection device 4 is also used to overcome part of the gravity of the flip plate 21 and the pedal 22, and the weight of the flip plate 21 and the pedal 22 is overcome by the cooperation of the torsion spring 235 and the spring 43.

[0079] When the vehicle is operating normally, the auxiliary picking device 2 is closed, which does not occupy the driver's space and is convenient for getting on and off the vehicle. At this time, the auxiliary picking device 2 presses the pedal 22 under the action of the torsion spring 235 set on its rotating shaft 234 to keep it closed; a raised positioning block 8 is set on the frame 1, which can make the strong magnet 7 fixed on the flip plate 21 suck the positioning block 8 of the frame 1 to maintain the position and avoid the accidental opening of the auxiliary picking device 2 when the vehicle is driven suddenly and bumpy. At this time, the detection device 4 does not detect the standing person, and the whole vehicle is operating normally.

[0080] When picking operations are required, the driver can open the auxiliary picking device 2 by hand to disengage it from the position holding state. As the pedal 22 rotates around the rotating shaft 234 to a certain angle (20-30 degrees), the center of gravity of the pedal 22 moves backward, so that the torque generated by its center of gravity is greater than the holding torque of the torsion spring 235. The pedal 22 will slowly open to the bottom and contact the detection device 4. At this time, the auxiliary picking device 2 is opened. At this time, a nylon block 41 is provided on the detection device 4 to contact the pedal 22 opened to the bottom. The nylon block 41 can avoid metal collision sound. The nylon block 41 is provided with a spring 43 and a detection switch 42 below it. Under the action of the spring 43, the nylon block 41 is separated from the detection switch 42 and supports the pedal 22 it contacts. At this time, although the auxiliary picking device 2 is opened, the detection device 4 does not detect anyone standing, and the entire vehicle can still operate normally. When the driver starts to pick goods, he can stop the vehicle and the standing person When picking goods from high-rise shelves on the auxiliary picking device 2, under the gravity of the driver, the pedal 22 and the nylon block 41 of the detection device 4 are pressed down and contact the detection switch 42, and the detection switch 42 is triggered. The control device controls the whole vehicle to enter the auxiliary picking mode, that is, the control device prohibits the vehicle's accelerator, lifting and lowering functions to prevent the accelerator or lifting and lowering switches from malfunctioning or other people's misoperation from causing accidental movement or lifting and lowering of the vehicle, and at the same time turns on devices such as buzzers and warning lights to remind the driver and surrounding workers to pay attention; after the picking is completed, after the driver gets off the auxiliary picking device 2, the spring 43 in the detection device 4 supports the nylon block 41 and the pedal 22, so that the nylon block 41 is separated from the detection device 4. At this time, there is no need to put away the auxiliary picking device 2, and the whole vehicle can also operate normally. When continuous picking operations are required, there is no need to frequently close and open the auxiliary picking device 2, which can greatly improve efficiency.

[0081] Please refer to Figure 7 A control method for an auxiliary picking device of an industrial vehicle is applied to the auxiliary picking device of the industrial vehicle, and the control method comprises:

[0082] Step S1, determining the operating status of the accelerator, the fork lifting drive device, the buzzer and the warning light through the control device;

[0083] Step S2, when the control device does not receive the signal from the detection device 4, the accelerator button and the fork lift button are in an effective state, and the buzzer and the warning light are controlled to be turned off;

[0084] Step S3: When the control device receives the signal from the detection device 4, the accelerator button and the fork lift button are in an invalid state, and the buzzer and the warning light are turned on.

[0085] It is understandable that when the control device does not receive a signal from the detection device 4, the control device controls the accelerator to start, so that the auxiliary picking device of the industrial vehicle operates normally, controls the fork lifting drive device to start, so that the auxiliary picking device of the industrial vehicle drives the fork to continue to lift normally, or controls the auxiliary picking device of the industrial vehicle to operate normally and controls the fork to lift and move normally, and controls the buzzer and warning light to turn off. When the control device receives a signal from the detection device 4, it controls the accelerator and the fork lifting drive device to stop running, and the vehicle enters the auxiliary picking mode, and controls the buzzer and warning light to turn on to alert the driver and surrounding workers.

[0086] It should be noted that the industrial vehicle has a unified control device, and also has an accelerator button and a fork lift button connected to the control device signal. The control device is also connected to the corresponding accelerator and fork lift drive device signal. When the industrial vehicle is in a normal starting state, the operator operates the corresponding accelerator button and fork lift button to trigger the corresponding control logic in the control device, thereby controlling the operation state of the accelerator and fork lift drive device. The accelerator button and fork lift button mentioned in the method are in an effective state, which means that the control device can normally receive the signal transmitted by the accelerator button and fork lift button. At this time, only when the operator operates the accelerator button and fork lift button, the signal will be sent to the control device to start the corresponding accelerator and fork lift drive device to work; the accelerator button and fork lift button mentioned in the method are in an invalid state, which means that the control device has shielded the signal transmitted by the accelerator button and fork lift button. At this time, even if the operator operates the accelerator button and fork lift button, the signal will not be sent to the control device, thereby avoiding safety accidents caused by the operator accidentally touching the accelerator button and fork lift button.

[0087] In the above embodiment, when the control device does not receive the signal from the detection device 4, it includes:

[0088] The auxiliary picking device 2 is in a folded state;

[0089] The auxiliary picking device 2 is in an open state, and no one is standing on the auxiliary picking device 2 .

[0090] It should be noted that, in this embodiment, there are two situations in which the control device does not receive the signal from the detection device 4. One is that the auxiliary picking device 2 is in a folded state, and the other is that the auxiliary picking device 2 is in an open state and no one is standing on the auxiliary picking device 2.

[0091] In the above embodiment, when the control device receives the signal from the detection device 4, it includes:

[0092] The auxiliary picking device 2 is in an open state, and a person stands on the auxiliary picking device 2 .

[0093] It can be understood that, in this embodiment, the detection device 4 will be triggered only when the auxiliary picking device 2 is in the open state and a person stands on the auxiliary picking device 2, and the control device can then receive the signal from the detection device 4.

[0094] In summary, the auxiliary picking device for industrial vehicles provided by the present invention has the functions of folding, position holding, opening buffering, and standing person detection. It is folded during normal driving and does not occupy the driving space. It can be opened when needed. When the auxiliary picking device 2 detects a standing person, the control device enters the auxiliary picking mode, and can control the vehicle to be unable to move and lift. At the same time, the buzzer and warning lights are controlled to turn on, thereby improving the safety of the picking personnel's operation. When it is detected that no one is standing, the vehicle can operate normally. Therefore, when continuous picking operations are required, the folding pedal 22 does not need to be folded, and the vehicle can also operate, which greatly improves the picking efficiency.
