Abstract
The utility model discloses a high-altitude working platform support with double protection, which is composed of four screw rod leveling supports and four inverse overturning supports, wherein the screw rod leveling supports and the inverse overturning supports are respectively arranged on the turning corners of the circumference of a working platform bottom rack. The screw rod leveling supports of the high-altitude working platform support with double protection are in screw rod structure, and the inverse overturning supports are in folded structure. When the high-altitude working platform support with double protection works, the four screw rod leveling supports and the four inverse overturning supports bear the vertical load and the overturning moment of a high-altitude working platform together, and the stress is caused to become more reasonable. Therefore, the high-altitude working platform support increases the working reliability of the high-altitude working platform.
Description
The utility model relates to the supporting leg that a kind of aerial work platform is used.
The flexible separate type that the supporting leg of existing aerial work platform generally adopts square metal tubing to make, the aerial work platform supporting leg of this flexible separate type is to avoid it to take excessive area, under off working state, the separated attitude of its supporting leg and job platform.And when using, then must carry out existing field boundary and install.Lose if some supporting legs occur, job platform promptly can't be worked.Brought very big inconvenience to the user thus.In addition, mainly stressed during owing to this class aerial work platform work by four supporting legs, so its leg structure is comparatively huge.Like this, not only waste material, and the too heaviness that seems.
The utility model is intended to overcome above-mentioned shortcoming, provides a kind of structure light and handy, easy to use and aerial work platform supporting leg with double protection functions.
The technical solution of the utility model is achieved like this: it is made of four screw rod leveling supporting legs and four anti-turning over supporting legs.Four screw rod leveling supporting legs and four anti-turning over supporting legs be installed in the working platform underframe around the corner, anti-turning over supporting leg adopts accordion structure.During work, eight supporting legs bear the vertical load and the tilting complex torque of aerial work platform jointly, make its more reasonable stress.When off working state, anti-turning over supporting leg can fold contraction, can reduce its floor space effectively.
Not only compact conformation, floor space are little through the utility model after the above-mentioned design, and have the double protection functions of support platform vertical load and anti-tilting complex torque.
Concrete structure of the present utility model is as shown in drawings:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a vertical view of the present utility model
Fig. 3 is the structural representation of screw rod leveling supporting leg of the present utility model
Fig. 4 is the structural representation of anti-turning over supporting leg of the present utility model
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:
A kind of aerial work platform supporting leg of duplicate protection is made of four screw rod leveling supporting legs 1 and four anti-turning over supporting legs 2.Four screw rod leveling supporting legs 1 and four anti-turning over supporting legs 2 are installed in the corner of working platform underframe 3 respectively.Screw rod leveling supporting leg 1 is made of flange base 4, screw rod 5, lever 6 and handle 7.Anti-turning over supporting leg 2 is an accordion structure, is made of supporting leg seat 8, draw money on credit strut 12 and short support bar 10.One end of short support bar 10 and the end of supporting leg seat 8 are hinged by screw 9, and the other end is hinged with the strut 12 of drawing money on credit.The strut 12 of drawing money on credit can rotate around hinged screw 8, makes folding movement up and down.End at the strut of drawing money on credit is provided with leg 13, and the other end is provided with top board 14.Leg 13 is movably connected with the strut of drawing money on credit, so that leg 13 can land on uneven ground.Top board 14 adopts screw, can change or shrink, to adapt to landing of uneven ground.On supporting leg seat 8, then be provided with location tooth bar 15.In addition, in short support bar 10, also be provided with latch 11, be used for the location when drawing in the strut of drawing money on credit is folding.
Working method of the present utility model is achieved like this:
Aerial work platform when work, earlier with four screw rod leveling supporting legs 1 with the job platform underframe location that lands.Then four anti-turning over supporting legs 2 are launched, the leg 13 of an end of its strut 2 of drawing money on credit is landed, the top board 14 of the other end is meshed with location tooth bar 15 on the supporting leg seat 8.At this moment, aerial work platform has vertical load and the tilting complex torque that eight supporting legs bear job platform jointly, makes its stressed optimum state that reaches.
Behind the aerial work platform end-of-job, can by screw rod leveling supporting leg 1 anti-turning over supporting leg 2 be loosened earlier.At this moment, the short support bar 10 of anti-turning over supporting leg can be moved downward around screw 9 earlier, the top board 14 of strut 12 ends of drawing money on credit and the location tooth bar 15 on the supporting leg seat 8 are separated.Then, will lack support bar 10 and rotate counterclockwise, drive the folding together contraction of the strut of drawing money on credit, and be fixed on the supporting leg seat with latch 11.Like this, just can reduce the occupation of land space of aerial work platform greatly, improve it and pass through performance.
