Specific embodiment
The structure in the present invention is further described with specific embodiment with reference to the accompanying drawing, but not as this
The restriction of invention.
As shown in Fig. 1~5, the embodiment of the invention discloses in a kind of mobile height-adjustable construction ladder, including frame
Inclined ladder 1, frame column 2, Vierendeel girder 3, platform board 4, non-floating rail 5, movable railing 6 and pedestal idler wheel 8, the frame column 2 are equipped with
Multiple and be vertically arranged, the pedestal idler wheel 8 is mounted on the bottom of frame column 2, the Vierendeel girder 3 laterally setting and connection framework
Column 2, the platform board 4 is horizontally disposed and is fixed between Vierendeel girder 3 and frame column 2, and one end of inclined ladder 1 is fixed on frame in frame
It sets a roof beam in place on 3, the other end of inclined ladder 1 is fixed on ground or another layer of Vierendeel girder 3 in frame, the platform board 4 towards bridge 9
Movable railing 6 is arranged in one end, and non-floating rail 5 is arranged in one end backwards to the platform board 4 of bridge 9.
The installation method of ladder at the scene of constructing is as follows: at the construction field (site) in use, pedestal idler wheel 8 is mounted on frame first
On the bottom plate of trestle 2, then first layer Vierendeel girder 3, platform board 4 are installed, inclined ladder 1, non-floating rail 5, movable railing 6, connect in frame
Each layer is successively installed from bottom to top, notice that the guard rail of each layer when installation will be synchronized with the installation of each layer platform board 4
Installation, prevents the safety accident that falls from high altitude.When mobile construction ladder position, inside the construction ladder must not there are personnel,
It constructs after ladder movement in place, just allows construction personnel to enter inside construction ladder after pedestal idler wheel need to being braked and carry out work of ascending a height
Industry.
The frame column shares 12, and frame column is being transversely provided with 3, and longitudinal to be equipped with 4, platform board is arranged in longitudinal phase
Between two adjacent frame columns, the length of platform board is equidistant with lateral three frame columns, and platform board is longitudinally spaced
Distribution.
The bottom of inclined ladder 1 is arranged between the two rows among longitudinal framing column in first box frame, the platform board of first layer
One end be arranged on longitudinal rear 2 frame columns, longitudinal preceding 2 frame columns are arranged in one end of the platform board of the second layer
On, successively it is spaced apart.
Platform board is respectively 1.2m, 2.4m, 3.6m, 4.8m, 6m away from ground elevation.
In construction 1.2m, 2.4m, 3.6m, 4.8m, the construction position of 6m absolute altitude can be directly entered by opening movable railing
It sets.
The planar dimension of the construction ladder is 3m × 2.4m, and the height of inclined ladder is 1.2m, entire frame in every layer of frame
Height is 7.2m, and frame column is the round tube of D50 × 3, and inclined ladder is 10# channel steel in Vierendeel girder, frame, and platform board is the flower of 3mm thickness
Line steel plate, non-floating rail and movable railing are that the round tube of D32 × 2.5, frame column and Vierendeel girder are connected using the high-strength bolt of M16
It connects, the bottom plate of movable railing is connect with Vierendeel girder using the high-strength bolt of M16.It is readily transported and the installing and dismounting at scene works.
It further include top inclined ladder 7, top inclined ladder 7 is mounted on the top exit of construction ladder.
Top inclined ladder height is 0.6m.When bridge elevation of top is not just in 1.2m, 2.4m, 3.6m, 4.8m, at 6m absolute altitude
When, the gentle of construction ladder platform absolute altitude and bridge height can be realized by installing inclined ladder 7 at the top of this in 4 exit of platform board
Overlap joint.
There is the connection elliptical aperture of spacing difference 300mm in two groups of short transverses below the terraced beam of top inclined ladder.
The selection of 7 use state of top inclined ladder is as follows:
(1) within the outlet of platform board 4 is flushed than bridge top or landing outlet is 0~300mm higher than bridge top
When, without installing top inclined ladder, personnel can facilitate disengaging stair channel.
(2) when platform board 4 is exported than high 300mm~600mm at the top of bridge, by the bolt hole below the inclined ladder ladder beam of top
It is connect with landing beam.
(3) when platform board 4 is exported than high 600mm~900mm at the top of bridge, by the bolt hole among the inclined ladder ladder beam of top
It is connect with landing beam.
(4) when platform board 4 export than flush at the top of bridge or landing outlet than 900~1200mm high at the top of bridge with
When interior, without installing top inclined ladder, upper bridge directly can be exported by lower layer's landing, because lower layer's landing exports at this time
It is flushed with bridge top or landing outlet is than 0~300mm high at the top of bridge, personnel can facilitate disengaging stair channel.
By the above method, construction ladder of the invention realizes construction personnel and safely enters between 0~6m absolute altitude
It ascends a height operation.
Construction ladder should precoat a priming paint and finishing coat before use, and guard rail finishing coat color should be yellow, to prevent
Xiu Tong in ladder use process of only constructing is needed if the case where painting breakage Huo Xiu Tong occurs in use in construction ladder
Coating is carried out to paint broken parts.
This frame structure always weighs about 1.8 tons, is supported and is moved with 12 pedestal idler wheels, and pedestal idler wheel uses single pressure-bearing
300kg, the universal wheel standard component of band brake.
Presently preferred embodiments of the present invention is described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, devices and structures not described in detail herein should be understood as gives reality with the common mode in this field
It applies；Anyone skilled in the art, without departing from the scope of the technical proposal of the invention, all using the disclosure above
Methods and technical content many possible changes and modifications are made to technical solution of the present invention, or be revised as equivalent variations etc.
Embodiment is imitated, this is not affected the essence of the present invention.Therefore, anything that does not depart from the technical scheme of the invention, foundation
