Abstract

The utility model relates to a removable scaffold, relating to a scaffold which is especially suitable for finishing inner and outer eaves of a building, composed of a left and a right side frames, a draw rod, a working platform, a supporting rod, a caster wheel and a staging ladder. The oblong working platform is arranged on the left and the right side frames through fixed lock catches at both ends; the height of the working platform can be lifted by using a plurality of side frames which are vertically sheathed, and the working platform can be directly climbed through the staging ladder; the scaffold can be kept stable by the supporting rod, and the scaffold can be entirely moved and positioned through the caster wheel. The utility model has the advantages of reasonable structure, and convenient dismounting, dismounting and movement. The utility model can be widely used for finishing the inner and the outer eaves of buildings, manufacturing large size advertising boards, and arranging large size displaying boards.

Description

Jenny scaffold

The utility model relates to a kind of scaffold that is specially adapted to building inner and outer eaves fitment operation.

Scaffold is a requisite facility in the building inner and outer eaves fitment operation, has very in the building decoration engineering construction and uses widely.Mostly scaffold of the prior art is the fixed scaffold that utilizes scattered steel or timber temporarily to build before construction, treat also must remove on the spot after the engineering completion.It is very big that workload is not only built and removed to this fixed scaffold, and will expend a large amount of steel and timber, and when especially the scope of operation is longer, the volume of scaffold will be very huge, and it is more outstanding that the problems referred to above will become.

The purpose of this utility model promptly is to design a kind of easy installation and removal and can the whole jenny scaffold that moves, and with the workload that scaffold was built or removed in minimizing, reduces the consumption of steel or timber simultaneously.

To achieve these goals, two bogie side frames and pull bar constitute the support body of scaffold and utilize strut to keep the stable of support body about the utility model utilization, job platform is installed on the left and right side frame by fixed snap close and 4 castors is installed, can constitute a kind of jenny scaffold in the bottom of support body.Adopt the vertical socket of more piece bogie side frame can promote the height of job platform, can climb up job platform straight by the ladder of going up on the stage that is fixed on arbitrary bogie side frame.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model jenny scaffold.

Accompanying drawing 1 is the structural representation of the utility model jenny scaffold;

The structural representation of joint support body headed by the accompanying drawing 2;

Accompanying drawing 3 and accompanying drawing 4 are respectively the structural representation of job platform and castor;

Accompanying drawing 5 and accompanying drawing 6 are respectively the structural representation and the three-dimensional cutaway view of automatic snap close.

With reference to the accompanying drawings 1～6, the utility model jenny scaffold mainly is made of bogie side frame, pull bar, job platform, strut, castor and the ladder of going up on the stage.Bogie side frame comprises left frame and left side frame, is formed by connecting by two root posts 1 and several cross bar 2, and the bottom of column 1 has the outer tube with castor or the socket of following joint side frame column, and the top of column 1 then has the inner sleeve with the socket of last joint side frame column.Pull bar comprises horizontal drawing bar and diagonal member, and the two ends of horizontal drawing bar 3 link to each other with the left and right side frame cross bar respectively and can make things convenient for demolition by automatic snap close 4, the two ends of diagonal member 5 by automatic snap close 6 respectively with joint or go up joint left and right side frame cross bar and link to each other and also can make things convenient for demolition.Working platform 7 is a rectangle, and the fixed snap close 8 by two ends links to each other with the left and right side frame cross bar respectively and can make things convenient for demolition.Strut 9 is a telescopic sleeve pipe, tilt to be installed in the front side of front column or the rear side of rear column, its top links to each other with column by helical latch 10 and can be for convenience detach, its bottom has antiskid glue cushion 11 and contacts with ground by antiskid glue cushion 11, and its middle part links to each other with column by helical latch 12 and short rod 13 and can be for convenience detach.Castor comprises 4 universal caster wheels 14 that have arrestment mechanism, be installed in the lower end of first joint side frame column respectively and work in coordination with column, its top has the interior external threading pipe 15 with the column socket, has the Height Adjustment nut 16 of working in coordination with column bottom outer tube on the interior external threading pipe.The ladder of going up on the stage 17 is fixed on left frame or the left side frame, can climb up job platform straight by it.

Automatically snap close is that a vitals of the present utility model and quantity are more, it mainly by the snap close main body and be installed on the snap close main body and work in coordination in locking plate and outer locking plate constitute.Snap close main body 18 is semicircle opening sleeve, has the arc groove of locking plate and outer locking plate in being used to install in its semi-circumference.In locking plate 19 be arc, be installed in the arc groove of snap close main body 18 by bearing pin 20 and can swing around bearing pin, its lower end and snap close main body 18 form latch openings, its outside has a ratchet 21.On the snap close main body in locking plate 19 outsides and can be around bearing pin 23 left-right rotation, its inboard has the ratchet 25 of working in coordination with lining locking plate ratchet 21 in outer locking plate 22 was installed in by bearing pin 23 and spring 24, and its lower end has the top dog 26 of locking plate lower end in the roof pressure.When automatic snap close button during to connecting tube,

lining locking plate

19 and 22 whiles of outer locking plate put left and latch openings are magnified; After connecting tube entered automatic snap close, outer locking plate 22 locking plate 19 in return and pushing tow under the effect of spring 24 made it to hold tightly connecting tube and passes through ratchet 21 and ratchet 25 lockings.

The utility model is rational in infrastructure, mounts and dismounts all easily, can make by castor that scaffold is whole to be moved, and utilizes the vertical socket of more piece bogie side frame can promote the height of job platform arbitrarily.The utility model also can be used for an operation such as layout of large board making and large exhibition board except that being specially adapted to building inner and outer eaves fitment operation.
