Abstract
A ladder equilibrator is disclosed by the utility model, which comprises a ladder and cushion sockets that sheathe ladder feet. The cushion sockets are provided with flexible ropes to connect the cushion sockets with adjacent ones, and the ladder is on the flexible ropes. Pulleys are equipped with supporting axles at joints of the ladder and the flexible ropes. The utility model is simple in structure, excellent in fitness of environment, increases usage modes and application areas of conventional ladders, and by introducing such a utility model, ladders can be used on land with altitude difference as usual and operators can work more conveniently.
Description
Technical field
The utility model relates to the ladder field, specifically is a kind of bascule of ladder.
Background technology
Ladder is applicable to various places as the indispensable instrument of ordinary maintenance emergency work.But present ladder can only be on the ground of same level could stable placement, otherwise fall down easily.For example can't normally place ladder having between the stair level of difference in height, make troubles and worried for like this operator's routine work.
In order to overcome above-mentioned shortcoming, handled easily person's operation needs, and the utility model provides ladder bascule a kind of simple in structure, safe and reliable, easy to use.
The utility model content
Goal of the invention of the present utility model is achieved by the following scheme: a kind of ladder bascule, comprise ladder and the pad tube that is placed on the foot of ladder, and wherein the pad tube is provided with a flexible rope that is communicated with the adjacent pads tube, and ladder places on the flexible rope.
Described ladder and flexible rope contact position are provided with the pulley of being installed by bolster.
The foot of ladder of described ladder is provided with groove, and pulley is installed on the groove location place.
Described pulley is installed on the bracket by bolster.
Described bracket is located at the medial surface of foot of ladder.
Described foot of ladder is provided with the sliding sleeve that reduces both frictional resistance with the fit face of pad tube.
The inside wall of described pad tube side is provided with the pedal of Convenient pad tube location.
Described pad tube is made of the hexahedron of three sides of tool only.
The parallel two sides of described pad tube are all extended spacing convex shoulder opposite to each other.
The top of pad tube sidewall is fixed in described flexible rope termination.
The utility model is simple in structure, and environmental suitability is strong, has strengthened the mode of occupation and the application of traditional ladder, makes ladder make things convenient for operator's work having use as usual between the face of land of difference in height.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the first example structure exploded view of the present utility model;
Fig. 2 is the first embodiment user mode plan view of the present utility model;
Fig. 3 second example structure exploded view of the present utility model;
Fig. 4 is the second embodiment user mode plan view of the present utility model.
The specific embodiment
The utility model ladder bascule, comprise ladder and the pad tube 2 that is placed on the foot of ladder 11, as shown in the figure, pad tube 2 is provided with flexible rope 3, the top of pad tube 2 sidewalls is fixed in flexible rope 3 terminations, the foot of ladder 11 of ladder places on the flexible rope 3, and ladder and flexible rope 3 contact positions are provided with the pulley of being installed by bolster 4.Pad tube 2 is provided with the pedal 6 of Convenient pad tube 2 location, and pedal 6 is located at the inside wall of pad tube 2 sides, parallels with the foot rest 12 of ladder.
When ladder used in the height rolling ground, because ladder is combined closely with pad tube 2, pad tube 2 may not glide automatically, is supported on the ground, and the pedal 6 that can tramp with one's feet this moment slides on the ground pad tube for 2 times, supports ladder.
Pad tube 2 is made of the hexahedron of three sides of tool only, and two sides parallel to each other are all extended spacing convex shoulder 21 opposite to each other on the pad tube 2, and spacing convex shoulder 21 can prevent that ladder from deviating from from the open side of pad tube 2.
First example structure of the present utility model is simple, as shown in Figure 1, is provided with groove 13 in foot of ladder 11, and pulley 4 is installed in the groove 13, and flexible rope 3 is located at pad tube 2 inside, passes groove 13 and contacts with pulley 4.
The second example structure compactness of the present utility model as shown in Figure 3, is provided with bracket 5 in the medial surface of foot of ladder 11, and pulley 4 is installed on the bracket 5.Should be because of the change in location of pulley 4, flexible rope 3 is located at pad tube 2 outsides thereupon, passes bracket 5 and contacts with pulley 4.And in order to reduce the frictional resistance between foot of ladder 11 and the pad tube 2, foot of ladder 11 is provided with sliding sleeve 7 with the fit face of pad tube 2, and the shape size of sliding sleeve 7 is suitable with pad tube 2, and is provided with shrinkage pool 71 in response to pedal 6, and is convenient for assembly and use.
