Description
Technical field
The utility model is related to maintenance of equipment technical field, and in particular to a kind of multi-stag suspension ladder.
Background technology
In the prior art, in production plant, need to carry out the maintenance and maintenance of equipment often.And in order to high-altitude mesh
Mark thing is overhauled, it is necessary to which ladder carries out operation.And object height is different, the demand for ladder is also just different, across
Big object is spent, ladder length can not be too short, and long ladder is not suitable for the small object of span yet, therefore, right
Storage, selection in ladder also just seem particularly necessary.
Utility model content
The utility model aims to provide a kind of multi-stag suspension ladder, to solve the above problems.
To achieve the above object, the technical solution of the utility model is as follows：
A kind of multi-stag suspension ladder, it is characterised in that：Including multistage ladder, one-level ladder upper outside is provided with connection
Hole, remaining ladder is provided with connecting hole in inner side in addition to one-level ladder；Stock screw is connected with the connecting hole.
Further, deep floor is welded with the ladder, connecting hole is welded on deep floor.
Further, it is provided with foot-driven lever in the ladder.
Further, the connecting hole is attaching nut.
The beneficial effects of the utility model are：The utility model is simple in construction, easily realizes, mutual using multistage ladder
The form of connection realizes quick detachable packing and connection.And connecting hole is passed through by screw rod or screw, by ladder one-level one-level phase
Mutual clamping, overall structure is stable, is difficult to rock, and security performance is high.
Brief description of the drawings
Fig. 1 is the terraced structural representation of multi-stag suspension that the utility model is provided.
Marked in figure：1 it is one-level ladder, 2 be connecting hole, 3 be foot-driven lever, 4 be two grades of ladders, 5 is deep floor.
Embodiment
The utility model is described further with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of multi-stag hangs ladder, including multistage ladder, the upper outside of one-level ladder 1 is provided with connecting hole
