Abstract

The utility model discloses a ladder assembly with the capacity of automatic moving that includes a front ladder assembly upright pipe, a back ladder assembly upright pipe and a ladder assembly horizontal pipe; wherein, the lower end of the back ladder assembly upright pipe is sleeved with two driving wheels; the lower end of the front ladder assembly upright pipe is sleeved with a directive wheel. The consumer stands on the ladder assembly top, thus the ladder assembly is capable of moving automatically during utilization; besides, the direction of the ladder assembly is controlled and the position of the ladder assembly is fixed.

Description

A kind of ladder that can walk automatically

The utility model relates to a kind of ladder that can walk automatically.

At present, people are at the electrician's of family chamber interior line, advertising decoration etc., and general what use is the herringbone ladder, in the process of using, when the shift position, will descend ladder, and mobile ladder is very inconvenient.

The purpose of this utility model is to provide a kind of ladder that can walk automatically to solve people when using ladder, the inconvenience of mobile ladder.

The novel ladder that can walk automatically of this use is made up of preceding ladder standpipe, back ladder standpipe, ladder transverse tube, the lower end socket of described ladder standpipe afterwards two driving wheels; A driving shaft is arranged between two driving wheels, a gear-box has been fixed on the right of driving shaft, a bevel gear and a bevel gear that is socketed in the traction drive shaft lower end that is fixed on the driving shaft is housed in the gear-box, traction drive shaft is contained in the ladder standpipe, before described the lower end socket of ladder standpipe turn to wheel carrier, turn to wheel carrier the lower end each fixed a minor axis and sprocket wheel, be with a chain on two sprocket wheels, turn to the middle part of wheel carrier respectively to overlap a steel bowl and a bearing, be fixed on the axle that turns to wheel carrier upper end and pass the lower end that steel bowl and bearing holder (housing, cover) are connected on the deflecting roller power transmission shaft.

Adopt said structure, the ladder that can walk automatically, people not only can move to ladder the position of own needs freely at ladder, and easy to use, flexibly take up room little, simple in structure.

Fig. 1 is the front view of the novel ladder that can walk automatically of this use

Fig. 2 is the rear elevation of the novel ladder that can walk automatically of this use

Fig. 3 is the front elevation drawing of the novel ladder that can walk automatically of this use

Fig. 4 is the 1-1 sectional drawing of the novel ladder that can walk automatically of this use

The ladder that can walk automatically of the present utility model as shown in Figure 1 is by preceding ladder standpipe 16, back ladder standpipe 2, the deflecting roller 13 of ladder standpipe 16 lower ends before being socketed in, be socketed in the driving wheel 5 of ladder standpipe 2 lower ends, back, junction plate 5 between preceding ladder standpipe 16 and the back ladder stand 2, support bar 10 is formed, as shown in Figure 2, a driving shaft 14 is arranged in the driving wheel 5, a gear-box 8 is arranged on the driving shaft 14, have one to be fixed on the bevel gear 7 on the driving shaft 14 and to be fixed on a bevel gear 6 with driving wheel turning cylinder 4 ends in the gear-box 8, bevel gear 7 meshes with bevel gear 6, shakes driving wheel wind 11, traction drive shaft 4 rotates, the bevel gear 6 that drives the end rotates, and drives bevel gear 7 simultaneously and rotates, and drives driving wheel 5 and moves.As shown in Figure 3, deflecting roller 3 is socketed on the preceding ladder standpipe 16, a minor axis 26 is respectively arranged on two deflecting rollers 13, each is fixed one and turns to wheel carrier 23 on the minor axis 26, turn to the bottom of wheel carrier 23 that a sprocket wheel 22 is respectively arranged, a chain 20 is arranged between two sprocket wheels 22, turn to the middle part of wheel carrier 23 that a steel bowl 24 is respectively arranged, turn to the top of wheel carrier 23 to be enclosed within the bearing 25, the axle 27 on the top that turns to wheel carrier 23 on the right passes through from bearing 25, with 12 sockets of deflecting roller power transmission shaft, the top of axle 27 is public affairs six side plugs 28, and the bottom of deflecting roller power transmission shaft is a mother six side plugs 29, the top of power transmission shaft 12 is deflecting roller winds 11, shake wind 11, drive deflecting roller power transmission shaft 12 and rotate, drive simultaneously and turn to wheel carrier 23 rotations, also driven and be fixed on left side sprocket wheel 22 rotations that turn on the wheel carrier, the sprocket wheel 22 on the left side rotates by the sprocket wheel 22 that chain 20 drives the right, just can change deflecting roller 13 directions, the frictional force when steel bowl 20 and bearing 25 can alleviate deflecting roller 13 change directions.

People are when using ladder of walking of the present utility model, support body directly can be socketed in the position that deflecting roller 13 and driving wheel 5 can be fixed ladder, will be mobile during ladder, shake deflecting roller wind 11, drive deflecting roller 13 and rotate, determined direction after, shake driving wheel wind 1, drive driving wheel 5 and rotate the position of walking and oneself needing.When deflecting roller wind 11 is shaken deflecting roller 13 and forwards angle with 5 one-tenth 90 ° of driving wheels to, just can fix ladder and not move front, rear, left and right.
