Description

Technical Field

[0001] This utility model relates to the field of lifting platform technology, and in particular to a convenient lifting platform for pruning garden trees. Background Technology

[0002] In landscaping maintenance, tree pruning is a common and important high-altitude task. Currently, workers typically rely on traditional ladders or aerial work platforms. Traditional ladders suffer from insufficient stability, limited working height, and require frequent and strenuous movement, increasing labor intensity and safety hazards due to the need for workers to move up and down frequently. While professional aerial work platforms are powerful, they are often bulky, expensive, and poorly adapted to narrow or uneven terrain in gardens, making them difficult to deploy and use flexibly in complex garden environments. Furthermore, the operating control mechanisms of many existing lifting platforms are often directly exposed, making them prone to accidental contact or stepping during operation, leading to misoperation and safety accidents. Utility Model Content

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Please refer to Figures 1 to 5 : Example 1: This utility model proposes a convenient garden tree pruning lifting platform, including: a movable base 1; a battery box 2 is fixedly installed at one end of the top plane of the movable base 1, and an inverted U-shaped push rod 3 is fixedly fixed vertically upward on the movable base 1 on the side where the battery box 2 is located; an upper seat 6 is provided above the movable base 1, and a shear frame 4 and a lifting drive frame 5 are provided between the movable base 1 and the upper seat 6. There are two shear frames 4, which are respectively placed on the upper and lower sides of the lifting drive frame 5 and connected to the movable base 1 and the upper seat 6; a tray 7 is fixedly installed on the top of the upper seat 6.

[0016] Among them, the four corners of the bottom plane of the mobile base 1 are provided with casters 101.

[0017] The lifting drive frame 5 has a lead screw 501 rotatably mounted through its middle section. A motor 502 is fixedly mounted at one end of the lifting drive frame 5. The shaft of the motor 502 is fixedly connected to one end of the lead screw 501. The other end of the lead screw 501 is vertically screwed through the other end of the lifting drive frame 5. The two ends of the lifting drive frame 5 are rotatably connected to connecting arms 503. The two connecting arms 503 are rotatably connected to one shear arm of each of the upper and lower shear frames 4. The two connecting arms 503 and the shear arms of the shear frames 4 connected to them together form a parallelogram structure. The rotation of the lead screw 501 drives the two shear frames 4 to rise and fall, and the upper seat 6 rises and falls accordingly.

[0018] The tray 7 has a structure that is wider at the top and narrower at the bottom. Anti-slip side strips 701 are evenly spaced vertically on the four inclined surfaces of the inner cavity of the tray 7.

[0019] The tray 7 has two control pedals 706 on the inner side wall near the push rod 3. The upper and lower sides of the tray 7 have an upper plate 703 and a lower plate 702 respectively. An anti-stepping plate 704 is slidably engaged between the upper plate 703 and the lower plate 702. The lower plate 702 has a notch 7021 on the side away from the control pedal 706 for removing the anti-stepping plate 704. A magnetic stop 705 is fixed on the side wall of the tray 7 away from the notch 7021 of the control pedal 706. The magnetic stop 705 is made of magnet, and the anti-stepping plate 704 is made of magnetic material. The magnetic stop 705 attracts the anti-stepping plate 704, and the anti-stepping plate 704 covers the control pedal 706.

[0020] In Example 2, based on Example 1, the surface of the anti-slip plate 704 is provided with evenly spaced anti-slip protrusions 7041. When the anti-slip plate 704 is pushed to one side, the control pedal 706 is exposed.

[0021] The following further explains the function and effect of each structure mentioned above, so that those skilled in the art can better understand the technical solution: The movable base 1 enables the movement and support of the entire equipment. The casters 101 at the four corners of its bottom allow the platform to move easily and be precisely positioned, greatly improving the flexibility and efficiency of garden work. The battery box 2 at the top of the movable base 1 provides a stable power supply to the equipment, ensuring reliable operation of the lifting drive and other electric functions in outdoor environments. The inverted U-shaped push rod 3 serves as a handle, making it easy for users to push and operate the equipment, enhancing the convenience of operation. The core of the lifting function is achieved by the scissor frame 4 and the lifting drive frame 5 working together. The motor 502 in the lifting drive frame 5 drives the lead screw 501 to rotate, which is connected to the scissor arms of the upper and lower scissor frames 4 through the connecting arm 503 to form a parallelogram structure, thereby driving the upper seat 6 to rise and fall smoothly. This design ensures the stability and safety of the lifting process and avoids sudden descent or swaying. The tray 7 on top of the upper seat 6 serves as a work platform, featuring a structure that is wider at the top and narrower at the bottom, and includes internal anti-slip side strips 701 to effectively prevent tools or items from slipping, thus improving safety during operation. The control pedal 706 on the tray 7 is used to control the lifting operation. It is fitted with an anti-stepping plate 704 via an upper plate 703 and a lower plate 702. The anti-stepping plate 704 is magnetically attached to the control pedal 706 by a magnetic stop 705 to prevent accidental triggering of the lifting operation. At the same time, the anti-slip protrusions 7041 on the surface of the anti-stepping plate 704 increase the friction of the feet, further ensuring operational stability. The anti-stepping plate 704 can be removed via a notch 7021 in the lower plate 702 for easy maintenance and adjustment.

[0022] Working Principle: First, the user pushes the device to a suitable position in the garden where the trees to be pruned are located using the push rod 3. The casters 101 at the bottom of the movable base 1 ensure flexibility and convenience of movement. After positioning, the operator climbs onto the tray 7 on top of the upper seat 6 to prepare for work. When lifting is required, simply use your foot to push the anti-stepping plate 704 to one side, allowing it to slide against the magnetic attraction of the magnetic stop 705, thus exposing the control pedal 706 below. The anti-slip protrusions 7041 on the surface of the anti-stepping plate 704 provide good friction when pushing and stepping. Then, stepping on the control pedal 706 triggers a signal to start the motor 502 in the lifting drive frame 5. The motor 502 operates and drives the lead screw 501 connected to it to rotate. The rotational motion of the lead screw 501 is converted into linear motion through the screwed components, driving the connecting arms 503 at both ends to move. Since the two connecting arms 503 are rotatably connected to the shear arms of the upper and lower shear frames 4 respectively, forming a parallelogram structure together, the movement of the connecting arms 503 will force the two shear frames 4 to extend or retract in a coordinated manner, thereby achieving smooth and reliable vertical lifting of the upper seat 6 and its top tray 7. During this process, the structure of the tray 7, which is wider at the top and narrower at the bottom, and the anti-slip side strips 701 vertically arranged on the four inclined surfaces of its inner cavity, can effectively prevent the trimming tools placed on it from slipping off, ensuring the safety of high-altitude operations. After the operation is completed, the control pedal 706 is stepped down again to lower the platform to the lowest position, and then the anti-step plate 704 is slid back to its original position, so that it is attracted and fixed by the magnetic stop 705, and covers the control pedal 706 again. This design effectively prevents accidental stepping when not in operation. If it is necessary to clean and maintain the anti-step plate 704 or the control pedal 706, the anti-step plate 704 can be easily removed through the notch 7021 opened on the lower clamping plate 702.
