DETAILED DESCRIPTION

[0021] 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.

[0022] Reference Figure 1-6 A movable lifting platform for a grape corridor comprises a platform vehicle and two horizontal guide rails 1. The two guide rails 1 are laid on the ground below the grape corridor along the length direction of the grape corridor. The platform vehicle comprises a base 2. The bottom end of the base 2 is provided with wheels 3 through legs. The wheels 3 are wheels 3 with an annular groove in the middle. The wheels 3 roll along the guide rails 1. The top of the base 2 is connected with a platform board 5 through a plurality of first hydraulic telescopic rods 4. The platform board 5 is surrounded by fences 6 to prevent workers from falling from the platform board 5. An anti-head collision mechanism is provided at the top of the platform board 5. Cleaning brake mechanisms are provided on the front and rear sides of the bottom end of the base 2 to clean the guide rails 1 and complete the braking work.

[0023] In this embodiment, the anti-head collision mechanism includes four supporting vertical rods 7, four touch rods 8 and a rectangular supporting frame 9. The bottom end of each supporting vertical rod 7 is fixedly connected to the platform plate 5 by bolts, and the top end of each supporting vertical rod 7 is provided with a mounting hole. One end of each touch rod 8 is slidably installed in a corresponding mounting hole, and the other end extends out of the mounting hole and is fixedly connected to the rectangular supporting frame 9. An annular baffle 10 is fixedly connected to the part of the touch rod 8 located in the mounting hole, and a push switch 11 is installed at the bottom end of the mounting hole. A first spring 12 is sleeved on the position of the touch rod 8 located at the lower end of the annular baffle 10, the top end of the first spring 12 is fixedly connected to the bottom of the touch rod 8, and the bottom end of the first spring 12 is fixedly connected to the bottom wall of the mounting hole. An alarm 13 is installed on the rectangular supporting frame 9, and the alarm 13 forms a closed loop with a battery 14 fixedly installed on the top of the base 2 through each push switch 11. When the rectangular support frame 9 is not subjected to downward pressure, the touch rod 8 is in a state of being separated from the push switch 11 under the elastic force of the first spring 12. When the staff controls the platform board 5 to rise, the rectangular support frame 9 will also rise. When the rectangular support frame 9 touches the top of the grape gallery, the rectangular support frame 9 is subjected to downward pressure, thereby driving the touch rod 8 to overcome the elastic force of the first spring 12 and move downward and touch the push switch 11. At this time, the alarm 13 will sound an alarm, thereby reminding the staff to control the platform board 5 to stop rising. The alarm 13 forms a closed loop with the battery 14 fixedly installed on the top of the base 2 through each push switch 11, that is, as long as one touch rod 8 contacts the push switch 11, the alarm 13 will sound an alarm, thereby improving safety.

[0024] In this embodiment, a driving motor 15 is fixedly mounted on the base 2, a driving pulley is fixedly connected to the output shaft of the driving motor 15, a driven pulley is fixedly mounted on one end of the wheel axle of the wheel 3, and the driving pulley and the corresponding driven pulley are connected via a belt transmission. In this embodiment, the driving motor 15 can drive the wheel 3 to rotate, thereby driving the lifting platform to move along the guide rail 1.

[0025] In this embodiment, a cleaning brake mechanism is provided directly above each guide rail 1 at the front and rear ends of the base 2, and the wheels 3 on each guide rail 1 are located between the two cleaning brake mechanisms. That is, no matter whether the lifting platform moves forward or backward, there is a cleaning brake mechanism to clean the guide rail 1 in advance, thereby ensuring the normal movement of the lifting platform.

[0026] In this embodiment, the cleaning brake mechanism includes a second hydraulic telescopic rod 16, the top end of the second hydraulic telescopic rod 16 is fixedly connected to the base 2, the bottom end of the second hydraulic telescopic rod 16 is fixedly connected to a mounting plate 17, the bottom end of the mounting plate 17 is rotatably connected to a brake plate 18 on the side close to the wheel 3, a torsion spring 19 is connected between the brake plate 18 and the mounting plate 17, a brake pad 20 is installed on the lower surface of the brake plate 18, and a cleaning plate 21 is vertically connected to the top of the end of the brake plate 18 away from the wheel 3, and the cleaning plate 21 is used to push away debris that has fallen on the guide rail 1. During the movement of the lifting platform, the second hydraulic telescopic rod 16 is in a retracted state, and the brake plate 18 forms a certain angle with the mounting plate 17 under the action of the torsion spring 19. At this time, the bottom end of the cleaning plate 21 contacts the guide rail 1, and the debris dropped on the guide rail 1 is pushed away by the cleaning plate 21, thereby preventing derailment. When the lifting platform moves into place and needs to stop, the second hydraulic telescopic rod 16 is controlled to extend, driving the mounting plate 17 to move downward. After the brake plate 18 is subjected to pressure, the angle between it and the mounting plate 17 gradually decreases until the two are in contact. At this time, the brake pad 20 on the bottom of the brake plate 18 is squeezed and rubbed with the guide rail 1, thereby achieving braking of the lifting platform and ensuring that the lifting platform can be paused at a certain position.

[0027] In this embodiment, a chamfer is provided at the bottom end of the connection between the cleaning plate 21 and the brake plate 18, and a roller 22 is rotatably installed at the chamfer. The setting of the roller 22 can reduce the resistance of the cleaning plate 21 relative to the guide rail 1.

[0028] In this embodiment, the left and right ends of the platform plate 5 are slidably mounted with extension plates 23, and the bottom ends of the extension plates 23 are fixedly connected with a plurality of support cross bars 24, which are arranged along the sliding direction of the extension plates 23. One end of the support cross bar 24 is slidably mounted inside the platform plate 5 and the bottom end thereof is fixedly connected with an anti-dropout clamping table 25, which can prevent the extension plate 23 and the support cross bar 24 from excessively sliding outward and detaching from the platform plate 5. The extension plate 23 is also provided with a fence, and the fences at the front and rear ends of the extension plate 23 are slidably mounted in the fences 6 at the front and rear ends of the platform plate 5, respectively, so that they can be extended along with the extension plate 23 to ensure the safety of the staff.

[0029] In this embodiment, a ladder 26 is fixedly connected to the front end and / or the rear end of the platform board 5, so that the staff can easily climb onto the platform board 5 to perform pruning operations.

[0030] The present invention can also be used for grape picking during the picking period. When used for grape picking, the anti-collision head mechanism needs to be removed as a whole to prevent the anti-collision head mechanism from knocking off or damaging the grape fruit.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
