Description
Technical Field
The utility model belongs to the technical field of the climbing device technique and specifically relates to an instrument formula cat ladder with adjustable.
Background
The ladder stand is a common device and is widely applied to the fields of engineering construction and the like. The ladder stand structure generally comprises an integrated ladder structure and two sections, wherein the integrated ladder structure is a known ladder structure and comprises two longitudinal beams, and a plurality of pedals are fixedly arranged between the longitudinal beams at uniform intervals; the two-section type ladder is characterized in that the two-section type ladder is connected with another ladder on the basis of an integrated type, and when the two-section type ladder is used, if one ladder is not long enough, the other ladder is extended through a connecting structure such as a pull rope.
However, both of the above ladders have some disadvantages, firstly, the distance between two adjacent pedals is fixed, so the stride cannot be adjusted according to the actual use condition and the actual user, and in addition, the existing ladder is relatively suitable for simple families or maintenance, but in the building process, such as the construction process of attic, because constructors need to bear a large number of tools or building materials sometimes in the climbing process, the stability of the existing ladder is not enough to meet the existing working requirements.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art, and provides an adjustable tool type crawling ladder which is reasonable in structure, adjustable in stride and convenient to fix.
The utility model adopts the technical proposal that:
the utility model provides an instrument formula cat ladder with adjustable, includes the perpendicular roof beam that two parallel intervals set up, its characterized in that: the vertical beams are made of square tube materials, the end faces, opposite to the square tubes, of the two square tubes are arranged to be pedal installation faces, the two end faces, adjacent to the pedal installation faces, of the two pedal installation faces are arranged to be hook installation faces, multiple groups of pedal installation holes are formed in the two pedal installation faces at intervals, a pedal is movably installed between the pedal installation holes at the same height, the upper end portions and the lower end portions of the two vertical beams are evenly formed in the hook installation faces at intervals, and hooks are symmetrically fixed in the hook installation holes in the end faces, climbed back to people, of the vertical beams.
And each group of pedal mounting holes in each square tube comprises two pedal mounting holes which are arranged at intervals in the same group, and the straight line formed by the centers of the two pedal mounting holes is parallel to the extending direction of the vertical beam.
And the two sides of each pedal are respectively provided with an installation plate integrally, each installation plate is vertical to the pedal, through holes are symmetrically formed in the two installation plates of the same pedal, and the positions and the inner diameters of the through holes and the pedal installation holes correspond to each other.
The utility model has the advantages that:
the utility model discloses in, adopt two to erect the footboard of the mobile installation of roof beam cooperation to make up, in the in-service use process, it is different according to operational environment's the condition, the interval of adjacent footboard is adjusted to the couple of removable different shapes and the dismouting through bolt and nut, promotes its adaptability.
The utility model discloses in, every group footboard mounting hole adopts homonymy two, the mounting panel that the structure cooperation footboard of arranging two pairs together made can carry out the multiple spot installation, the atress that has disperseed the footboard promptly promotes its security, also can prevent effectively that the footboard from taking place to rotate along circumference, the footboard is fixed with the angle that erects the roof beam and be under the mounted state, consequently, the footboard can adopt the board-like structure that the area is bigger, promote the steadiness of trampling the in-process, form simple and easy stair structure, need not hand can climb, the staff of being convenient for bear a burden scrambles.

Detailed Description
The present invention is further illustrated by the following examples, which are intended to be illustrative, not limiting and are not intended to limit the scope of the invention.
The utility model provides an instrument formula cat ladder with adjustable, includes two parallel interval settings perpendicular 2, the utility model discloses an innovation lies in, erect the roof beam and adopt the square pipe material to make, two terminal surfaces that square pipe is relative set up to footboard installation face, and the both ends face adjacent with footboard installation face sets up to the couple installation face, interval system goes out multiunit footboard mounting hole 1 in two footboard installation faces, and movable mounting has a footboard 6 between the footboard mounting hole of same height, two upper end and the lower tip that erect the roof beam are even interval system a plurality of couple mounting holes in the couple mounting hole, wear to adorn bolt 4 in the couple mounting hole in the terminal surface of personnel's climbing dorsad to be fixed with couple 5 through 3 symmetries of nut.
In this embodiment, every group in every square tube the footboard mounting hole include two, with two footboard mounting holes interval settings in the same group, two footboard mounting hole centers are the straight line and are erected roof beam extending direction and parallel.
In the embodiment, two sides of each pedal are respectively provided with an installing plate 8 integrally, each installing plate is vertical to the pedal, through holes 7 are symmetrically formed in the two installing plates of the same pedal, and the positions and the inner diameters of the through holes and the pedal installing holes correspond to each other.
The utility model discloses a working process is:
the utility model discloses during the use, different according to operational environment's the condition, the couple of removable different shapes and the interval of adjusting adjacent footboard through the dismouting of bolt and nut adopt two to erect the footboard of roof beam cooperation mobile installation to make up.
The utility model discloses in, every group footboard mounting hole adopts homonymy two, the mounting panel that the structure cooperation footboard of arranging two pairs together made can carry out the multiple spot installation, the atress that has disperseed the footboard promptly promotes its security, also can prevent effectively that the footboard from taking place to rotate along circumference, the footboard is fixed with the angle that erects the roof beam and be under the mounted state, consequently, the footboard can adopt the board-like structure that the area is bigger, promote the steadiness of trampling the in-process, form simple and easy stair structure, need not hand can climb, the staff of being convenient for bear a burden scrambles.
