Embodiment 1
[0036] like figure 1 As shown, the outdoor work ladder includes a connecting bar 1, a fixed movable rod 2, a detachable supporting rod 3, a supporting connecting rod 4, a supporting frame 5, a fixed connecting rod 6, a fixed nail hole 7, a sole 8, and a sliding plate 9 , the lower ladder 10, the lower ladder fastening structure 11, the step bar 12, the middle ladder 13, the upper ladder fastening structure 14, the upper ladder 15, the metal frame 16, and the metal anti-skid plate 17. The upper ladder 15, the middle ladder 13, and the lower ladder 10 pass image 3 The shown side groove slides, and after sliding, between the upper ladder 15 and the middle ladder 13, and between the middle ladder 13 and the lower ladder 10, the lower ladder buckle structure 11 is engaged with the middle ladder step bar 12, and the upper ladder The fastening structure 14 is engaged with the step bar 12 of the upper ladder to achieve fixation, and the required height can be adjusted through the fa...
Embodiment 2
[0039] The difference from Example 1 is that it is made of square stainless steel material, the length of the upper ladder 15, the middle ladder 13, and the lower ladder 10 are all 2.2m, and the adjacent distance between the step bars 12 is 38cm; the number of support frame sections is 5 sections, Every joint length is 1.5m, and all the other operation modes are identical with embodiment 1.
Embodiment 3
[0041] The difference from Example 1 is that it is made of engineering plastic materials, the length of the upper ladder 15, the middle ladder 13, and the lower ladder 10 are all 2.0m, and the adjacent distance between the step bars 12 is 36cm; the number of support frame sections is 6 sections , the length of each section is 1.2cm, and all the other operating modes are the same as in Example 1.

Abstract
The invention discloses an outdoor operation ladder, and relates to a ladder device assisting outdoor operation in the forestry industry. The operation ladder comprises an upper ladder (15), a middle ladder (13), a lower ladder (10), a support bracket (5), a metal frame (16) and sliding-stopping plates (9). The operation ladder is characterized in that the support bracket (5) is folded through a stretching bushing; the support bracket (5) is connected and fixed with the upper ladder (15) and the metal frame (16) through bolts; a connecting stretcher bar (1) is arranged at the top of the upper ladder (15); the sliding-stopping plates (9) and base pins (8) are arranged at the bottom of the lower ladder (10); the base pins (8) can sink into the earth; and the sliding-stopping plates (9) can be used for preventing the lower ladder (10) from sinking into the earth. The outdoor operation ladder has the advantages of being capable of being quickly assembled and disassembled, easy to fold and carry, and applicable to artificial fruit tree pollination, fruit tree pruning, flower and fruit thinning, fruit collecting operation, and the like in the outdoor hillside land high-altitude forestry, and the ladder is provided with the metal frame similar to a bench plate, and the connecting bar which can be used by an operator for proper rest.
Description
technical field [0001] The invention relates to an outdoor work ladder, in particular to a ladder device for assisting forestry outdoor work. Background technique [0002] At present, the commonly used ladders of about 6m are mostly two-connected telescopic lifts, and three-connected ladders are rare, and due to the limitations of the design of the ladders, there are no ladders designed for outdoor operations, especially in forestry and agricultural outdoor operations. Because the time that the ladder that people generally use is carried out operation is shorter, so seldom see band bench in the traditional ladder design. In outdoor forestry operations: fruit tree artificial pollination, fruit tree pruning, flower thinning and fruit harvesting, etc., each operation takes a long time. The traditional operation method is that people stand on the ladder for a long time, and they are prone to fatigue, which leads to work efficiency. Low. And the traditional ladders are mainly n...
