Description
Technical field
The utility model relates to the agricultural overlapping bamboo of fruit-bearing forest bimber stair, especially a kind of overlapping bamboo bimber stair with connector that improves climbing safety, reduction carrying difficulty, is convenient to handling and reduction energy consumption.
Background technology
Bamboo bimber stair is widely used in people's daily production, for example, for agricultural product being realized to the transfer between lower position and eminence position, for fruit-picking and for pruning the daily productions such as branch of fruit tree.
The bamboo bimber stair of prior art generally comprises symmetrically arranged two main support columns, between two main support columns, by some crossbeam pole for climbing, connect as one, during use, people climb up step by step by crossbeam pole for climbing, realize the transfer of the position that hoists from lower position.The general height of bamboo bimber stair of this structure is 10 meters of left and right, and the bamboo bimber stair that general rural households use, just can not leave in indoor and cannot carry indoor with interior [being all generally 8 meters] at 10 meters because long.
Yet, people are in actual production process, the stair that often need to grow are realized the fruit of higher position [this higher position, place refers to the height that exceeds 10 meters] are plucked, and the fruit tree branch of higher position [this higher position, place refers to the height that exceeds 10 meters] is pruned.The common way of people is exactly that the main support column of two stair is overlapping, then by rope or steel wire, bundlees the fixing overlapping bamboo bimber stair [realizing the lengthening of bamboo bimber stair] that forms.Which has solved people to a certain extent aborning to exceeding the demand of stair height itself.But, in use, often, because the pliability of rope causes two stair to depart from from binding, cause security incident, and in binding process, for guaranteeing the fastness of binding, people kill knot by rope often, after finishing using, with cutter, cut off rope, realize the separation of two stair, the rope that cutter cuts off cannot utilize again, waste resource; Strong than rope binding by the stair fastness of steel wire bundle, but binding with separated in quite consuming time, the handling difficulty of two stair is large.In the time need to being carried to other fruit-bearing forest from a slice fruit-bearing forest, because the stair handling difficulty of steel wire bundle is large, is all generally that the long stair after binding are directly carried, in handling process because long stair are easy to be stopped by other trees or house, difficult.
In sum, the problem that the overlapping bamboo bimber stair of prior art exists is: climbing safety is low, carrying difficulty is large, handling difficulty and energy consumption large.
