[0002] Lifting work platforms are used in exterior wall construction, interior decoration, equipment installation, and maintenance. Existing lifting work platforms are typically scissor lifts (common scissor lifts consist of multiple interlocking links), mast lifts (mast-supported lifting platforms rely on a mast for elevation), or boom lifts (boom lifts achieve elevation through boom extension). These structures offer relatively limited height and cannot meet the needs of high-altitude work positions. Currently, there is a lack of lifting work platforms that can be adjusted to the required height according to different work scenarios. Utility Model Content

[0024] This utility model features a relatively high guide column 11 and multiple sets of connecting rods 14 to fix any two adjacent connecting rods 14 on the same horizontal plane. The drive assembly 23 drives the upper and lower platforms 21 alternately and intermittently. While driving one platform 21, the other platform 21 is supported by a buckle 221 attached to the connecting rod 14. The lifting operation height is relatively high.

[0025] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0026] Example: Refer to Figures 1 to 4 A lifting work platform with a guiding mechanism includes four guide columns 11 arranged in a rectangular pattern. Multiple fixing rings 13 are arranged in a linear array on the guide columns 11. A connecting rod 14 is fixedly installed between any two adjacent fixing rings 13 on the same horizontal plane to form a rectangular connection. Four connecting rods 14 on the same plane form a group and contain multiple groups. The specific number of groups and relative density can be set according to the construction type.

[0027] Two platforms 21 are positioned between multiple guide columns 11. A drive assembly 23 is positioned between the two platforms 21. The drive assembly 23 drives the upper and lower platforms 21 alternately to continuously raise and lower them. Each platform 21 is equipped with a latch telescopic component 22, which includes four latches 221 symmetrically distributed in a matrix. The four latches 221 are driven to extend and retract synchronously. When one platform 21 is relatively fixed, the latches 221 are engaged with the connecting rod 14. When it is necessary to drive the upper platform 21 to rise, the platform 21 is first raised a set distance, such as 10cm. Then, the latch telescopic component 22 is driven to retract so that there is no overlap with the connecting rod 14 when viewed from above. The platform stops rising when it reaches a set distance above the previous set of connecting rods 14. Then, the latch telescopic component 22 is driven to extend so that it corresponds to the position of the corresponding connecting rod 14. Then, the latch telescopic component 22 is driven to descend so that it engages with the upper end of the connecting rod 14. The lower platform 21 can rise a certain distance by repeating the above actions. Repeating the above actions can continue to raise the platform. Conversely, reversing the operation can continue to lower the platform.

[0028] The fixing ring 13 has a plurality of annularly distributed pin holes 131. The pin holes 131 in any two adjacent fixing rings 13 on the same plane correspond to each other. The annularly distributed pin holes 131 can be continuously switched for connection to improve the service life of the entire fixing ring 13 and help to align two adjacent pin holes 131 used for connection.

[0029] To facilitate the connection of the connecting rod 14, two symmetrical pressure surfaces 141 and a notch 142 are provided at each end of the connecting rod 14. A pin hole 2 is provided on the pressure surface 141. A bolt and nut pair 15 is installed in both pin hole 131 and pin hole 2. When installation is required, the notch 142 is engaged with the retaining ring 13, and pin hole 131 and pin hole 2 are aligned. The bolt and nut pair 15 is then used to securely connect pin hole 131 and pin hole 2. Additionally, a pad 12 is fixed to the lower end of the guide post 11 to increase the contact area with the ground and provide high stability.

[0030] To achieve synchronous driving of the latches 221, the platform 21 is designed as a hollow structure; and the latch telescopic component 22 further includes: the latches 221 are semi-circular, one end of the two latches 221 located on the same side passes through the platform 21 and is fixedly connected to the synchronous plate 222, and a bidirectional telescopic component 223 for synchronously driving the two synchronous plates 222 is fixedly installed inside the platform 21. Existing telescopic devices with bidirectional screws can be used. When the horizontal position of the latches 221 does not affect the connecting rod 14, the bidirectional telescopic component 223 synchronously drives the two synchronous plates 222 to make the two pairs of latches 221 retract relative to each other or extend in opposite directions.

[0031] More specifically, the drive assembly 23 includes: a lifting rod 235 fixed to the lower end of the upper platform 21; a square frame embedded in the center of the lower platform 21, which is slidably connected to the lifting rod 235; a slot 231 on one side of the lifting rod 235; a rack 232 fixed inside one side of the slot 231; the rack 232 is a common rotary motor in the prior art; the rack 232 meshes with a gear 233; and a drive member 234 for driving the gear 233 is fixed on the square frame. After the position of the upper platform 21 is determined, the drive member 234 drives the bidirectional telescopic member 223 to mesh with the rack 232 and drive the lower platform 21 to rise. After the position of the lower platform 21 is determined, the drive member 234 drives the bidirectional telescopic member 223 to mesh with the rack 232 and drive the upper platform 21 to rise.

[0032] To monitor whether the platform 21 has passed the connecting rod 14, a distance sensor is embedded on one side of the platform 21. The distance sensor is electrically connected to a controller, which is electrically connected to a drive unit 234. After the distance sensor detects the connecting rod 14, the controller controls the drive unit 234 to work continuously for a set time, causing the platform 21 to rise 10 cm above the connecting rod 14.

[0033] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
