A kind of aerial ladder with two-stage linkage loading vehicle

Abstract

The invention relates to the technical field of engineering mechanical equipment, in particular to a scaling ladder having a second-stage linkage carrying truck. The scaling ladder is provided with a scaling ladder, a slide base, a shelf, a cable, pulleys, a wire winding wheel and a motor or a hydraulic motor, and is characterized in that a first-grade linkage base is arranged on the slide base, wherein the front end of the first-grade linkage base is hinged with a second-grade linkage base; the back end of the first-grade linkage base is hinged with the back end of the second-grade linkage base by an extension rod; the shelf is arranged on the second-grade linkage base; one end of the cable is connected with the shelf, and the other end is connected with the wire winding wheel on the scaling ladder after being bypassed through the pulley at the front end of the second-grade linkage base, the pulley at the back end of the first-grade linkage base, the pulley at the front end of the slide base, the pulley at the back end of the slide base and the pulley at the top end of the scaling ladder; a shaft of the wire winding wheel is connected with an output shaft of the motor or the hydraulic motor fixed on the scaling ladder; and the scaling ladder has such advantages as high safety coefficient, low labor intensity and high working efficiency.

Description

technical field [0001] The invention relates to the technical field of engineering machinery and equipment, in particular to an aerial ladder with a two-stage linkage loading vehicle with high safety factor, low labor intensity and high work efficiency. Background technique [0002] As we all know, with the development of economy and society, the construction of buildings in various places is getting higher and higher. This is a difficult problem for high-floor residents to decorate and move. Most of the high-floor residents use ladder trucks to carry large household items. And the rapid and safe transfer between the upper floor and the ground of the equipment. At present, the aerial ladder truck used for transportation is generally equipped with a guide rail on the aerial ladder, a sliding base on the guide rail, and a shelf on the sliding base. One end of the cable is connected to the shelf. Connection, the other end of the cable goes around the pulley at the top of the la...

[0002] As we all know, with the development of economy and society, the construction of buildings in various places is getting higher and higher. This is a difficult problem for high-floor residents to decorate and move. Most of the high-floor residents use ladder trucks to carry large household items. And the rapid and safe transfer between the upper floor and the ground of the equipment. At present, the aerial ladder truck used for transportation is generally equipped with a guide rail on the aerial ladder, a sliding base on the guide rail, and a shelf on the sliding base. One end of the cable is connected to the shelf. Connection, the other end of the cable goes around the pulley at the top of the ladder and connects to the winding wheel or winch on the ladder, the winding wheel shaft or winch shaft is connected to the output shaft of the motor or hydraulic motor fixed on the ladder, and the shelf on the ladder car When transporting to the highest point, because the top of the ladder is in contact with the wall, the front end of the shelf cannot touch the window, which increases the distance between the front end of the shelf and the window. When people carry it, there is a certain safety hazard. After the good goods reach the bottom, due to the limitation of the sliding base, when the carrier moves to the limit position at the bottom, the shelves are generally more than one meter above the ground, which increases the labor intensity for the staff on the ground, and the handling of goods Time-consuming
