Description

Technical Field

[0001] This utility model relates to the technical field of high-altitude operation protection equipment, specifically to a high-altitude operation safety protection device. Background Technology

[0002] Aerial work platforms are equipment used for working at heights in fields such as construction, power, communications, cleaning, installation, and maintenance. They can lift people, construction materials, and tools to a certain height via a work platform to carry out various construction operations.

[0003] Existing high-altitude safety devices are typically lifted and moved to the work location by a hoisting mechanism, after which workers on the device can process the area. These devices are generally work platforms surrounded by fencing to protect workers. However, when the fencing is fixed, height restrictions exist to accommodate different body types, reducing safety for some users. Existing solutions include height-adjustable fencing, as disclosed in utility model application number "202020804467.2," entitled "An Adjustable Height Fence for High-Altitude Vehicles." However, existing adjustable fencing solutions generally suffer from insufficient strength in the adjustment mechanism or susceptibility to damage. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please also refer to Figures 1 to 5 These are, respectively, an overall structural schematic diagram of the high-altitude operation safety protection device provided by this utility model, a sectional view at the work frame position, the fence position, and the movable fence position, and a partial enlarged view for showing the fixed components.

[0024] The safety protection device for working at height includes a work frame 11, a hanging frame 12, a fence 13, a movable fence 14, an adjustment component 2, a fixing component 3, a movable door 41, and a door lock 42.

[0025] The work frame 11 is a rectangular platform with columns at the four corners. A fixed railing 13 is installed on the inner side between adjacent columns, for a total of four railings 13. A movable railing 14 is installed on the outer side between adjacent columns, for a total of four movable railings 14. Specifically, a sliding groove is provided on the outer side of the column, connecting to the left and right sides of each movable railing 14, allowing the movable railing 14 to slide up and down under the constraint of the groove.

[0026] On the outermost side of the work frame 11, there is a hanger 12 that spans the middle area of ​​the work frame 11. This part of the structure is the same as existing similar products, so it will not be described in detail.

[0027] Located on the right (according to) Figure 1 (As shown in the view below, the same applies below) A shorter fence 13 and a movable fence 14 are provided with movable doors 41 at the same position. One side of each movable door 41 is hinged to fence 13 and movable fence 14 respectively, and the other side is connected to fence 13 and movable fence 14 respectively via door locks 42. The two movable doors 41 open in opposite directions, inward and outward.

[0028] Both fence 13 and movable fence 14 are triangular openwork structures, which cooperate to form an intersecting openwork structure. Fence 13 and movable fence 14 have a widened vertical member in the middle, which is used to set the adjustment component 2 and the fixing component 3, respectively.

[0029] Near the top of the widening component of fence 13, there is an inner cavity that is wider at the top and narrower at the bottom, referred to as the fence inner cavity. Below the inner cavity, there is a square through hole that penetrates fence 13. In the widening component of movable fence 14, there is a vertically extending inner cavity, referred to as the movable inner cavity.

[0030] The adjustment assembly 2 includes a rotating rod 21, an adjusting gear 22, a toothed block 23, a handle 24, and a fixed gear 25. The toothed block 23 is arranged vertically along the movable inner cavity, and the adjusting gear 22 is located in the movable inner cavity and meshes with the toothed block 23. The fixed gear 25 is located in a wider position within the inner cavity of the enclosure. The rotating rod 21 passes through both the inner cavity of the enclosure and the movable inner cavity, and is connected to both the fixed gear 25 and the adjusting gear 22. A handle 24 is provided on the inner surface of the enclosure 13 and is connected to the rotating rod 21.

[0031] In the above structure, by manually turning the handle 24, the rotating rod 21, the adjusting gear 22 and the fixed gear 25 are driven to rotate synchronously. The rotation of the adjusting gear 22 then pushes the toothed block 23 to move up and down, that is, it pushes the movable fence 14 to move up and down as a whole.

[0032] The fixing component 3 includes connecting rods 31, movable blocks 32, toothed plates 33, lead screws 34, moving blocks 35, and movable plates 36. Two connecting rods 31 are horizontally positioned in the wider part of the enclosure cavity, located above and below the fixed gear 25, respectively. The movable blocks 32 are vertically positioned and slidably connected to the two connecting rods 31. The two movable blocks 32 are respectively located on both sides of the fixed gear 25, and each has a toothed plate 33 on an adjacent side for engaging with the fixed gear 25.

[0033] In the above structure, by controlling the moving blocks 32 to move in opposite directions, the toothed plate 33 can engage with the fixed gear 25, thereby locking the entire adjusting assembly 2. Conversely, if the toothed plate 33 does not engage, the adjusting assembly 2 can normally push the movable fence 14 to move up and down.

[0034] The lead screw 34 is vertically positioned in a narrower part of the fence cavity. Its upper end is connected to the fence cavity via a bearing, its middle part is threaded to the moving block 35, its lower middle part is connected to the fence cavity via a bearing, and its lower end extends through a square through hole and is equipped with a protective sleeve. The moving block 35 abuts against the inner wall of the fence cavity, and the two movable blocks 32 are respectively hinged to the moving block 35 via a movable plate 36.

[0035] In the above structure, by manually rotating the lower end of the lead screw 34 in the square through hole, the moving block 35 can be driven to rise and fall, and then the moving block 35 can be driven to open or close through the movable plate 36, so that the toothed plate 33 and the fixed gear 25 can be released or engaged.

[0036] During use, staff enter and exit through the movable door 41. The lifting equipment is used for hoisting via the gantry 12. When it is necessary to adjust the height of the movable fence 14, first manually rotate the lower end of the screw 34 in the square through hole to disengage the toothed plate 33 from the fixed gear 25; then manually rotate the handle 24 to push the movable fence 14 to the appropriate height; finally, rotate the lower end of the screw 34 to lock the toothed plate 33 into the fixed gear 25, thus fixing the position of the movable fence 14.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
