Description

A kind of scaffold

Technical field

This utility model is related to construction operation technical field of auxiliary facilities, particularly to a kind of scaffold.

Background technology

In the production of industrial undertaking, run into when maintenance, installation and commissioning device it is often necessary to operator climb up Certain height is operated.Scaffold not only can solve vertically and horizontally to transport, and operator are played with good support Effect, thus it is widely used in the places such as construction site, internal work high above the ground.

The Chinese patent that Authorization Notice No. is CN201762973U, authorized announcement date is on 03 16th, 2011 discloses one Plant elevating scaffold, including the many column tubes being vertically arranged, by connecting rod, described column tube is connected, formed described Elevating scaffold support body, described self-lifting scaffold sets up many fall ways, the described column tube of described fall way insertion In, and the endoporus of the cylindrical and column tube of fall way forms gap cooperation；Each described column tube set multiple horizontal Fixed pin holes, set horizontal fixed pin holes in each described fall way, solid with the described fixed pin holes of steady pin insertion Fixed.

The endoporus that prior art passes through the cylindrical and column tube of fall way forms gap cooperation, the height of up-down adjustment scaffold Degree；Connect the multiple horizontal fixed pin holes of setting on fall way and column tube again, the steady pin that steady pin insertion is connected Kong Zhong, thus realizing the purpose of lift adjustment scaffold height, to be applied to the operation needs of differing heights.However, at one Complete to construct, when need to arrive its elsewhere and carrying out constructing operation, due to the space shared by scaffold larger it is more difficult to carry.

Utility model content

The purpose of this utility model is to provide a kind of scaffold, and the space which solving scaffold occupancy is larger and be difficult to remove It is transported to the problem that its elsewhere carries out constructing operation, reduces and take up room, have the advantages that to be easy to carry.

Above-mentioned technical purpose of the present utility model technical scheme is that：

A kind of scaffold, including bearing platform, is arranged on two bracing frames of bearing platform lower surface, support frame as described above includes two Root elevating lever and be connected to connecting rod between two elevating levers, support frame as described above is rotated with bearing platform and is connected, described load-bearing Platform includes symmetrically arranged first bearing platform and the second bearing platform and first, second bearing platform is connected by rotation, described first, The bearing strip be arrangeding in parallel is included on the second bearing platform, described connecting rod upper surface is hinged with for supporting the flexible of bracing frame Bar, one end of described expansion link is rotationally connected with bearing strip.

Using said structure, the bracing frame being rotationally connected with bearing platform is matched with expansion link, and expansion link shrinks, bracing frame Can turn down along the side being provided with expansion link, so that bracing frame is folded to bearing platform lower surface；First, second bearing platform rotates Connect, whole bearing platform doubling can be made, reduce the space shared by the application, be easy to carry.And between having between bearing strip Gap, reduces the overall weight of the application, and makes to be easy to during folding capture, consequently facilitating carrying.

More preferably：Described connecting rod lower surface is provided with fixed seat, connects between two described fixed seats relatively There is elastic part, described fixed seat includes fixed plate and rotating shaft, described fixed plate is arranged at below expansion link, and described rotating shaft is arranged in In two pieces of fixed plates, the two ends of described rotating shaft are provided with block piece, and described block piece is to stop side or latch.

Using said structure, elastic part can be used for adjusting the tightness between two bracing frames, makes with expansion link cooperation With, expansion link by bracing frame to outer support, and two bracing frames are strained by elastic part relatively, so that itself and bearing platform, support Frame, expansion link form entirety, strengthen the bonding strength between bracing frame and bearing platform simultaneously, so that the application tool after launching There is preferable stability, provide safety guarantee for operator.And fixed seat and the elastic part following table in connecting rod set along Face, that is, the elastic part position hinged with expansion link stagger, therefore, fold when, elastic part be difficult affect expansion link contraction and Fold.

More preferably：Described elastic part includes the first regulating bolt, the second regulating bolt and strainer, and described First, the second regulating bolt is bolted in the two ends of strainer respectively, and the other end of described first regulating bolt is connected in rotating shaft.

Using said structure, it is connected directly between the first regulating bolt in rotating shaft, to strainer and be connected on strainer The second regulating bolt there is supporting role.During adjusting elasticity part elasticity, directly can rotate strainer with handss It is adjusted, make operation become simple.When needing significantly adjusting elasticity part, first, second regulating bolt can be rotated simultaneously and enter Row is adjusted, and accelerates governing speed.

More preferably：Described elevating lever includes lifters and regulating part, and described lifters are sheathed on outside regulating part, Elastic extension structure is provided with described lifters, described regulating part is provided with and for inserting the logical of elastic extension structure Hole.

Using said structure, lifters can mutually be pulled open with regulating part, the elastic telescopic during pulling open, in lifters Structure is in regulating part slide outside, and the through hole on regulating part can make elastic extension structure be inserted, thus playing fixing Effect, makes the height of bracing frame keep constant.Pull elastic extension structure so as to depart from through hole, can be shunk, convenient folding Folded.

More preferably：Described elastic extension structure includes fixed cover, drawing article and spring, and described fixed cover is connected to Outside lifters, described drawing article includes barrier plate and the pull lever being located on barrier plate, and described spring housing is located at pull lever Outside and be arranged between fixed cover top and barrier plate.
