Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of forklifts, in particular to a semi-automatic adjustable operating platform and forklift. BACKGROUND

[0002] As the main force in the material handling equipment, the forklift is used for loading and unloading, stacking and short-distance transportation, and involves operations such as advancing and retreating, lifting and tilting, turning, switching driving mode, starting light, braking, and viewing instrument information. Currently, these operations of the forklift are generally realized through the operating platform and the buttons arranged on the upper end thereof. Whether the design of the operating platform is comfortable and reasonable will directly affect the operation of the forklift by the operator. With the rapid development of the warehousing and logistics industry, in order to cope with different working conditions, some forklifts that can freely switch between standing driving and sitting driving have appeared in the market. Standing driving for a long time will increase the fatigue of the driver and increase the driving risk, while sitting driving will lose part of the field of view. Therefore, the driving posture of the driver will change with the working condition, and the posture of the corresponding operating platform should also change. However, the existing technology is time-consuming and laborious when switching the posture of the operating platform.

[0003] The operating platform for the forklift provided in the publication CN212924299U is adjusted in height by sliding the second support relative to the first support and fixed on the first support by tightening the knob. During the tightening process, the opening of the second support is deformed to a smaller size and then pressed onto the first support to fix the second support. The angle adjustment function is realized by rotating the first support on the shaft of the mounting seat through the self-locking function of the gas spring. However, when adjusting the angle, one hand needs to release the self-locking function of the gas spring, and the other hand needs to rotate the operating platform. Therefore, when adjusting the height and angle, the hands need to be stretched to the side of the operating platform for operation. The knob for adjusting the height and the unlocking member for adjusting the angle are located on the side, which is difficult to observe directly due to the obstruction of the upper mechanism, and thus the operation is relatively troublesome. In addition, since the knob and the unlocking member are located on the side that cannot be directly observed, the leg is very easy to touch the knob and the unlocking member, which not only easily causes accidental touch, but also affects the operation of the leg. In the process of operating the forklift, it is very easy to cause danger. SUMMARY

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] Embodiment:

[0031] Please refer to Figures 1 to 7 The present application provides a technical solution:

[0032] A semi-automatic adjustable operation table, comprising a fixed assembly 100, a gas spring assembly 200, an adjusting assembly 300 and an operation table assembly 400, wherein:

[0033] The fixed assembly 100 is hollow inside and has an open upper end, and the adjusting assembly 300 is rotatably fixed to the open upper end of the fixed assembly 100.

[0034] Further, the fixed assembly 100 comprises a fixed seat 110 which is hollow inside and has an open upper end, a rotating shaft 120 is mounted to the inside upper end of the fixed seat 110, the adjusting assembly 300 is sleeved on the rotating shaft 120 at the lower end, the lower end of the adjusting assembly 300 can rotate around the rotating shaft 120, the inclination angle between the fixed assembly 100 and the adjusting assembly 300 is adjusted, and the angle of the entire operation table is adjusted, a first fixed shaft 130 is fixed inside the fixed seat 110, and the gas spring assembly 200 is sleeved on the first fixed shaft 130 at the lower end, the lower end of the gas spring assembly 200 can rotate around the first fixed shaft 130.

[0035] Optionally, the upper end of the fixed seat 110 and the lower end of the adjusting assembly 300 are connected by a hinge or a hinge, the lower end of the adjusting assembly 300 can rotate around the hinge or the hinge, and the inclination angle between the fixed assembly 100 and the adjusting assembly 300 is adjusted.

[0036] The lower end of the hollow interior of the adjustment component 300 is rotatably fixed inside the fixing component 100, and a lifting mechanism 340 is provided inside, with the lower end of the lifting mechanism 340 fixed on the adjustment component 300.

[0037] Furthermore, the adjustment assembly 300 includes an adjustment bracket 310 that is hollow inside and open at both the top and bottom. An arc-shaped rotating groove 311 is fixed at the bottom of the adjustment bracket 310. The rotating shaft 120 is located inside the rotating groove 311 and can rotate relative to the adjustment bracket 310 within the rotating groove 311. The arc-shaped rotating groove 311 can increase the angle of rotation. A second fixed shaft 320 is fixed inside the adjustment bracket 310. The upper end of the gas spring assembly 200 is sleeved on the second fixed shaft 320, and the upper end of the gas spring assembly 200 can rotate around the second fixed shaft 320.

[0038] Optionally, the arc-shaped rotating groove 311 can be replaced by a circular rotating hole with a diameter slightly larger than that of the rotating shaft 120, allowing the rotating shaft 120 to rotate relative to the adjusting bracket 310 within the rotating groove 311.

[0039] The lower end of the gas spring assembly 200 is rotatably fixed in the fixed assembly 100, and the upper end is rotatably fixed in the adjusting assembly 300, which is used to change the length to drive the adjusting assembly 300 to rotate.

[0040] Furthermore, the gas spring assembly 200 includes a controllable gas spring 210, with rotating joints 220 fixed at both the upper and lower ends of the controllable gas spring 210. The rotating joints 220 at the upper and lower ends are respectively fitted onto the second fixed shaft 320 and the first fixed shaft 130. The rotating joints 220 make the upper and lower ends of the gas spring assembly 200 rotate more smoothly around the second fixed shaft 320 and the first fixed shaft 130. The gas spring assembly 200 also includes a control unit 230, which is internally connected to the controllable gas spring 210 and is used to change the internal pressure of the controllable gas spring 210 to adjust the length of the controllable gas spring 210.

[0041] Optionally, the rotary joint 220 is provided with a bearing, which rotates around the second fixed shaft 320 and the first fixed shaft 130, thereby reducing the friction during rotation.

[0042] Furthermore, the control unit 230 employs a solenoid valve, which is connected to the pressure cylinder inside the gas spring assembly 200. When the solenoid valve is closed, the pressure in the pressure cylinder inside the gas spring assembly 200 cannot change, and the length of the gas spring assembly 200 cannot be adjusted. However, when the solenoid valve is open, adjusting the tilt angle of the adjusting component 300 will squeeze or stretch the gas spring assembly 200, causing its length to change. The gas in the pressure cylinder inside the gas spring assembly 200 will be adjusted through the solenoid valve. Therefore, when the solenoid valve is open, the entire gas spring assembly 200 is in an unlocked state, and its length can be adjusted. When the solenoid valve is closed, the entire gas spring assembly 200 is in a locked state, and its length cannot be adjusted.

[0043] Optionally, the control unit 230 may also be an air pump or a hydraulic pump, which changes the internal pressure of the pressure cylinder inside the gas spring assembly 200 to change the length of the gas spring assembly 200.

[0044] The lower end of the control panel assembly 400 is open and is fitted over the adjustment assembly 300. The upper end of the lifting mechanism 340 is fixed to the control panel assembly 400 and is used to push the control panel assembly 400 to move up and down.

[0045] Furthermore, the lifting mechanism 340 adopts an electric lifting rod, which drives the operating platform assembly 400 to move up and down.

[0046] Optionally, the lifting mechanism 340 may also be an electric screw jack.

[0047] The gas spring assembly 200 and the lifting mechanism 340 are both located inside the fixed assembly 100 and the adjusting assembly 300, and there are no adjusting mechanisms on the side. Therefore, they do not affect the operation of the legs during use, making it safer.

[0048] Furthermore, the operating table assembly 400 includes an operating table 410 and a mounting bracket 420 fixed to the bottom of the operating table 410. The lower end of the lifting mechanism 340 is fixed inside the adjusting assembly 300, and the upper end is fixed inside the mounting bracket 420.

[0049] Furthermore, a sliding block 330 is fixed inside the adjustment component 300, and a sliding groove 430 is fixed inside the mounting bracket 420. The sliding block 330 is slidably locked in the sliding groove 430, allowing the operating table component 400 to move more smoothly when it is raised and lowered.

[0050] The control panel assembly 400 is equipped with operation buttons for controlling the lifting mechanism 340 and the gas spring assembly 200.

[0051] Furthermore, a rotary switch 411 and a lifting switch 412 are fixed on the operating table 410. The rotary switch 411 controls the opening and closing of the control unit 230, and the lifting switch 412 controls the operation of the lifting mechanism 340. The rotary switch 411 is connected in series in the power circuit of the control unit 230, and the lifting switch 412 is connected in series in the power circuit of the lifting mechanism 340.

[0052] In addition, the operation buttons for controlling the lifting mechanism 340 and the control unit 230 are all located on the control panel 410. Therefore, when adjusting the height and angle, there is no need to reach to the side for blind operation. The operation can be performed intuitively, making it more convenient to adjust. The driver can easily adjust the height and angle of the control panel 410 while standing or sitting, ensuring safety during adjustment.

[0053] The present invention also provides a forklift, wherein the forklift includes a forklift body and an operating platform, the operating platform being mounted on the forklift body, and the operating platform being the aforementioned semi-automatic adjustable operating platform.

[0054] The working principle of this invention is as follows: After the semi-automatic adjustable control panel is installed on the forklift, the lifting mechanism 340 is controlled by the lifting switch 412 to work, which drives the control panel assembly 400 to move upward, thereby adjusting the height of the entire device so that the height of the control panel assembly 400 meets the needs of the driver. At this time, the sliding block 330 slides in the sliding groove 430, making the entire lifting process smoother.

[0055] When adjusting the height, the control unit 230 is operated by turning the switch 411 to unlock it. Then, the adjustment component 300 is pushed by the control panel assembly 400 to rotate around the rotation axis 120, thereby adjusting the tilt angle between the fixed component 100 and the adjustment component 300 so that the tilt angle of the control panel assembly 400 meets the driver's needs.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
