FIG. 2 is a schematic view of a driving frame
In the figure: 1-step ladder platform, 2-spring, 3-hinged bearing, 4-left ladder, 5-wedge brake block, 6-directional wheel, 7-right ladder, 8-angle limit stay wire, 9-pedal, 10-spring hole, 11-connecting rod, 12-hinged shaft and 13-frame body.
Detailed Description
As shown in figure 1, the self-propelled high-altitude decoration operation herringbone ladder structurally comprises a left side ladder 4, a right side ladder 7 and a stepping ladder platform 1, wherein the left side ladder 4 and the right side ladder 7 are respectively hinged below the stepping ladder platform 1 at the upper part, an angle limiting pull wire 8 is arranged between the left side ladder 4 and the right side ladder 7, the lower ends of the left ladder 4 and the right ladder 7 are provided with directional wheels 6, the left ladder 4 or the right ladder 7 is hinged with a driving frame, as shown in fig. 2, the driving frame comprises a frame body 13, a pedal 9 is arranged above the frame body 13, the lowest end of the driving frame is hinged with a wedge-shaped brake block 5, the middle part of the driving frame is provided with a hinged bearing 3, the driving frame is hinged with a left ladder 4 or a right ladder 7 through the hinged bearing 3, the upper part of the driving frame is connected with a spring 2, the other end of the spring 2 is connected with a stepping ladder platform 1, the pedal 9 is positioned on the outer side of the left side ladder 4 or the right side ladder 7, and the end of the wedge-shaped brake block 5 is positioned on the inner side of the left side ladder 4 or the right side ladder 7.
The pedal 9 and the frame body 13 are in an inclined cross connection shape, the cross angle can be set to be 30-90 degrees, the foot can conveniently and directly step on the pedal 9, and the frame body 13 can rotate by taking the hinge bearing 3 as an axis.
An antiskid rubber layer is arranged on the step 1, and an antiskid rubber layer is arranged on the pedal plate 9.
The angle limiting pull wire 8 is in a fixed length, so that when the herringbone ladder is opened and is in a static working state, the angle between the left side ladder 4 and the right side ladder 7 is controlled to be 35 degrees.
The lower part of the frame body 13 is provided with a connecting rod 11 to ensure the overall stability and no deformation of the frame body 13.
Meanwhile, the spring tightens the upper part of the frame body 13, and the wedge-shaped brake block 5 below the frame body 13 is inserted into the gap between the orientation wheel and the ground under the action of the hinge bearing 3. Under the tension state, the wedge-shaped brake block 5 can be clamped by the spring to be in a stable braking state by the aid of the rebound of the spring, and accordingly, safety operation of operators on the herringbone ladder is guaranteed.
When the herringbone ladder needs to advance and retreat, an operator does not need to descend the ladder, the herringbone ladder can be directly arranged on the herringbone ladder, the operator utilizes the force of two legs to inwards return and clamp, the opening and closing angle of the herringbone ladder is reduced from 35 degrees in working, meanwhile, the driving frame rotates for a certain angle by treading the pedal plate 9, the wedge-shaped brake pads 5 leave the directional wheel, the brake is released, then the pedal plate 9 is continuously treaded by feet, the driving frame drives the wedge-shaped brake pads to push the ground, the ground provides reaction force, the whole herringbone ladder moves forwards and backwards, and the driving frame is similar to a paddle. The aim of automatically walking is fulfilled for the operation of the double ladder operators on the ladder, the operation efficiency of the operators is improved, and the construction operation is facilitated.
