Abstract

The utility model relates to an operation frame that is used in climbing high operation. The technical problem to be solved is that the provided operation frame should have the characteristics of being convenient in dismounting, folding storage, simple in structure and stable and reliable. The technical schemes are: a folding operation frame, includes two gate-type frames erected on the two sides and pedals spreading on the frame, the end of each gate-type frames is provided with two universal wheels respectively. Between the two gate-type frames, a hinge joint is used, and on the two sides of the pedals the open adown fork ports are arranged respectively. The size of the fork ports goes together with the transverse retaining on the gate-type frame and can straddle across the transverse retaining actively. The composite page system knuckle connection is: the two side side frames of combination hinges are hinged on the columns of the left and right door type frames, and at least two hinge points are provided on each column. Positioning pins are arranged on the hinges of the composite page and anti-sliding vanes are provided on the edges of the pedals.

Description

A kind of folding operation frame

Technical field

The utility model relates to a kind of servicing unit of ascending a height and adopting when constructing, and specifically is the operation frame that adopts when ascend operation.

Background technology

People will use the operation frame usually when exceeding the occasion operation at human body height position; For example when the eminence position of main equipment outside being painted or indoor ceiling repaired, all need utilize the operation frame.Existing operation frame all is the framework of fixed structure, and the universal wheel of following dress activity is shelved the weight that pedal is used to carry the operator above so that move.The operation frame of this structure just occupies bigger parking space in the temporary transient not time spent, thereby stores cumbersome owing to non-dismountable.

The utility model content

Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of improvement of operation frame is provided, and this operation frame should have the characteristics of easy accessibility, foldable for storage, and simple in structure, reliable and stable.

The technical scheme that the utility model proposes is:

A kind of folding operation frame, comprise two portal frames that are erected at two limits and be tiled in pedal on the framework, the bottom of each portal frame is equipped with two universal wheels respectively, adopt hinge-type hinge to connect between described two portal frames, two sides of described pedal bottom are shaped on downward opening prong respectively, and the size of prong and the crosspiece on the portal frame match and straddle movably on the described crosspiece.

Described hinge-type hinge connects; Two frames forming hinge are hinged on respectively on the column of portal frame on left side and right side, and have two at least with pin joint on each column.

Also be shaped on shop bolt on the described hinge-type hinge.

Described pedal edge also is shaped on anti-slide plate.

The utility model is because the portal frame construction that has adopted hinge-type hinge to connect, and dismantles and assembles very convenient 1 two portal frames are drawn back, and to set up pedal can install; Carry pedal off folding the drawing close of two portal frames promptly finished dismounting; When after assembling is finished, using, become horizontal crossbeam across the pedal of two frameworks and played the effect of reinforcing operation post, make operation post more reliable and more stable as operation post; After the dismounting, two collapsible drawing close of portal frame, thus reduced to deposit shared space greatly.The structure of whole device is also very simple in addition, thereby manufacturing is also comparatively convenient, and cost is not high yet.

The specific embodiment

As shown in the figure, this operation frame comprises two portal frames 1 that are erected at two limits and the pedal 2 that is tiled on the framework; It is one that each portal frame can adopt horizontal and vertical tubing to fix (generally being welding), and the bottom of portal frame is equipped with two universal wheels 3 respectively; The configurable one or a few blocks pedal 2 of each operation frame, two sides of described pedal bottom are shaped on downward opening prong 2-1 respectively, and the size of the prong of described pedal and the crosspiece on the portal frame adapt and straddle movably on the described crosspiece.Obviously, this respective outer side edges mode of pedal and crosspiece can significantly strengthen the stability of operation frame.

Also adopt hinge-type hinge 4 to connect between described two portal frames, the structure of this hinge-type hinge is; Two the frame 4-1 and the 4-2 that form hinge are hinged on respectively on the column of portal frame on left side and right side, and have two (having shown two pin joints among Fig. 1) at least with pin joint on each column.Among Fig. 3 also as can be known: frame 4-1 fixes (welding) outside at sleeve pipe 4-3, and axis 4-4 interts in the pore of sleeve pipe 4-3, and two ends of frame 4-2 also fixing (welding) are at two ends (two ends that expose jacket exterior) of axis; In addition, two ports of sleeve pipe also are respectively installed with packing ring 4-5 and 4-6.

Fig. 4 has shown the syndeton of frame and column: be set with rotating sliding sleeve 4-2-1 on the column 1-1, two ends up and down of this sliding sleeve are limited by fixing (can weld) supporting slice 1-1-1 on column respectively, and sliding sleeve 4-2-1 fixing again (generally also being welding) is on the top of frame 4-2 (other frame also is same the connection with column).Hence one can see that, and frame is that hinge is connected with column.Nature, the hinge connection also can this type of push to adopt otherwise, and for those skilled in the art, this is conspicuous.

Also as can be known,, also adopt shop bolt 4-7 on the hinge-type hinge among Fig. 3 for improving security performance.This dowel fixes is on spring, and in spring is positioned at axis 4-4; Pin passes the tube wall of axis by the spring pressure roof pressure, and inserting outward behind the pin-and-hole of sleeve pipe 4-3 is locking hinge (drawing omission), makes frame 4-1 and 4-2 remain on a plane, and then guarantees that the operation frame is more firm.During dismounting, the order of only with hand pressing pin top is contracted thereafter and is broken away from the pin-and-hole of sleeve pipe 4-3, and hinge-type hinge is promptly rotatable.

The bottom of pallet 5 shown in Figure 7 also is shaped on two joint 5-1, can just in time be enclosed within two column tops of portal frame.Used material in the time of can temporarily putting operation on the pallet.

In addition, described pedal edge also is shaped on anti-slide plate 2-2, to improve operator's safety factor; Lock wheel apparatus (conventional equipment) also is housed, to guarantee that universal wheel can not rotate when the operation on the described universal wheel.
