Description

Technical Field

[0001] This utility model relates to the technical field of outdoor high-altitude construction tools, specifically to an electric hoisting platform. Background Technology

[0002] Electric hoisting platform is a type of decoration machinery that uses a motor to drive the work platform up and down along the construction facade. It is mainly used for exterior wall construction and decoration (such as plastering, tiling, and painting) of high-rise and multi-story buildings, as well as the installation and cleaning of curtain walls, doors and windows.

[0003] Some electric suspended platforms can also perform lifting and lowering operations on exterior walls, but these are relatively large. This technical solution targets smaller electric suspended platforms. Currently, electric suspended platforms for single-person use are still not lightweight enough, and their large size makes them inconvenient to transport and carry. During operation, when a person sits on the platform, they tend to lean forward or backward, which is uncomfortable. The reason for this is that in the existing design, the seat surface on the platform is perpendicular to the vertical beam, and combined with the unreasonable motor weight distribution, it is prone to imbalance. Moreover, current electric suspended platforms use steel wire ropes for traction, which are heavy and inconvenient to carry.

[0004] A prior Chinese patent application, application number CN202220432209.5, disclosed a drive device for a rope climbing machine. This drive device, as the main unit, can wind up the rope and therefore can be used as the traction main unit for the suspended platform. However, when this drive device is applied to the rope climbing machine, the direction of the rope entering and exiting is determined. When traction of heavy objects, the length direction of the rope climbing machine or its drive device is in a vertical state. If it is directly configured at the bottom of the suspended platform seat, it is inconvenient to use because the bottom of the suspended platform is too long.

[0005] Therefore, it is necessary to solve the problem of how the drive unit of the rope climbing machine, as the main drive unit of the electric suspended platform, can maintain the stability of the overall structure, the reliability of its operation, and the convenience and comfort of its use.

[0035] Example:

[0036] This invention discloses an electric hoisting platform, combined with... Figure 1 , Figure 2 and Figure 3 The structure includes a drive unit 1, a seat frame 2, a crossbeam 3, and a vertical beam 4. The crossbeam 3 and vertical beam 4 are fixed together to form an acute angle α, where 60° ≤ α < 90°. The seat surface of the seat frame 2 is tilted to match the crossbeam 3, keeping the crossbeam 3 in the middle of the seat frame 2. The vertical beam 4 is tilted relative to the vertical line of the front leg 21 of the seat frame 2. The drive unit 1 is placed horizontally and fixedly mounted on the crossbeam 3, with the rope inlet and outlet close to the front of the seat frame 2. The seat frame 2 has a backrest, which supports the lower back and also limits the movement of the person, improving safety. When using the chair, the worker places their legs on either side of the vertical beam 4, sits on the seat frame 2, and the seat surface provides support. The structure of the crossbeam 3 and vertical beam 4 resembles an inverted "7". Ropes can be threaded through the top of the vertical beam 4 and then into the drive unit 1. The drive unit 1 can reel in the ropes, allowing the suspended platform to lift the person. The drive unit 1 can reverse its direction to allow the suspended platform to descend slowly.

[0037] Material racks 25 are inserted into both sides of the seat frame 2. Rollers 23 are installed at the bottom of the front legs 21 of the seat frame 2, and support legs 24 are installed at the rear of the seat frame 2. The material racks 25 inserted into both sides of the seat frame 2 allow material buckets to be placed on them for workers performing exterior wall painting. The material racks 25 are detachable for transportation; their compact structure makes them suitable for single-person operation. They can be used to lift and lower a single person or material buckets, making them suitable for exterior wall construction and convenient to use.

[0038] exist Figure 2 As can be seen, the crossbeam 3 and the vertical beam 4 are fixed together to form an acute angle α, where 60° ≤ α < 90°. This structure can balance the human body posture, making the center of gravity close to the vertical line of the rope. By changing the angle between the crossbeam 3 and the vertical beam 4, the overall center of gravity design is adjusted. This helps the seat frame 2, when working with the drive unit 1, to maintain stable left-right balance during use. Furthermore, it allows the human body to adjust and balance its center of gravity and posture when seated, ensuring a comfortable posture when using the electric hanging platform, preventing excessive backward or forward leaning.

[0039] exist Figure 6As can be seen, fixing plates 5 are provided on both sides of the crossbeam 3. The two fixing plates 5 clamp the drive host 1 on both sides. The fixing plates 5 fix the crossbeam 3, the vertical beam 4, and the drive host 1. A bottom shell 6 is also fixed to the bottom of the seat frame 2. The bottom shell 6 is fixed to the front leg 21 and the rear leg 22 of the seat frame 2 to support the drive host 1. The addition of fixing plates 5 can further improve the firmness of the drive host 1 installation and reduce the shaking generated by the motor, making the overall operation more stable. The bottom shell 6 not only supports the drive host 1, but also has a protective effect to prevent it from being bumped.

[0040] A partition 7 is provided on the bottom shell 6, and a battery module 8 is installed on the rear side of the partition 7. An interface 61 for charging the battery module 8 is provided on the bottom shell 6.

A door 10 is provided on the bottom shell 6 at the location of the battery module 8. The door 10 is rotatably connected to the protective cover 9, and a latch 101 is provided on the door 10 to engage with the bottom shell 6. (Reference) Figure 1 and Figure 2 As shown. The battery module 8 has a certain weight. Considering its installation space and weight distribution, it is installed on the rear side of the drive motor, separated by a partition 7 for protection. It is also equipped with a door 10 to facilitate the replacement of the battery module 8 and to allow charging via the interface 61.

[0041] For ease of operation, the front of the bottom shell 6 is equipped with a rope outlet 62, a button 63, a display screen 64, and an observation window 65. The rope outlet 62 is directly opposite the rope outlet of the drive unit 1, and the observation window 65 is close to the rope inlet of the drive unit 1. The rope enters the rope inlet of the drive unit 1 through the hollow vertical beam 4. The button 63 is located on the front for easy operation in the air and can also be used on the ground. The drive motor enables the winding wheel 11 to wind up the rope. The observation window 65 allows users to adjust the rope by inserting their fingers through the rope end when the rope first enters the inlet / outlet assembly 14, as the rope end may not easily enter the rope inlet. It also allows users to observe the rope's usage status.

[0042] refer to Figure 4 and Figure 5The drive unit 1 includes a rope reel 11, a rope limiting frame 12, a rope limiting wheel 13, an inlet / outlet assembly 14, and an outlet pipe 15. The motor on the drive unit 1 provides drive power, and the battery module 8 provides power to the motor. The motor drives the rope reel 11 to rotate via a gear transmission structure, which is an existing structure and will not be described further. After assembly into the base shell 6, the rope limiting frame 12 partially surrounds the rope reel 11 to form a rope channel. The rope limiting wheel 13 is rotatably installed at the opening of the rope limiting frame 12. Inlet / outlet components are provided at the rope limiting wheel 13 and the rope entry / exit positions. The inlet / outlet components have guide channels for rope crossing, including an inlet rope channel and an outlet rope channel. The outlet pipe 15 is installed on the outlet rope channel. The inlet rope channel leads to the vertical beam 4 and is tangential to the rope reel 11. During use, the rope enters and exits in an orderly manner, following the defined channels.

[0043] For ease of transport, the vertical beam 4 is equipped with a folding structure 41, and guide wheels 42 are installed at the upper end of the vertical beam 4. This allows the vertical beam 4 to be folded for storage.

[0044] For outdoor use, especially in rainy weather or to prevent water accumulation, preferably, the bottom of the base 6 is provided with a drainage hole 66. This can prevent water accumulation.
