Description

A multi-purpose safety tool and appliance right-angle hanging ladder

technical field

The invention belongs to the technical field of electric power tools, and relates to a right-angle hanging ladder, in particular to a self-made "3+1" right-angle hanging ladder of multi-purpose safety tools.

Background technique

Ladders are highly used safety tools in transmission line maintenance operations. In the current transmission line maintenance work, the ladder tools used mainly include the following two types:

1. The hanging ladder used to enter the wire from the cross arm in the maintenance operation of the transmission line. When working, the hook at one end is hooked on the wire, and the other end is tied to the cross arm, so that the operator can enter the wire along the ladder without going through the insulator. This tool will cause scars to the wire, and the center of gravity of the operator will lean forward, which will result in long working hours and great physical exertion.

2. Ladders used in urban power grids. Because steel pipe towers are often used in urban power grids, it is difficult to get out of the line during maintenance operations. Using ladders can facilitate access to power failure conductors for maintenance operations.

The purpose of the present invention is solved by the following technical solutions:

The right-angle hanging ladder for multi-purpose safety equipment includes a first aluminum alloy climbing ladder section and a second aluminum alloy climbing ladder section; the ends of the first aluminum alloy climbing ladder section and the second aluminum alloy climbing ladder section are connected by an adjustable rotating shaft device; The adjustable rotating shaft device is provided with a lock; the outer end of the first aluminum alloy climbing section is provided with a fixed hook; the outer end of the second aluminum alloy climbing section is provided with a steering hook.

The length of the first aluminum alloy ladder section is 3 meters; the length of the second aluminum alloy ladder section is 1 meter.

The above-mentioned adjustable rotating shaft device is composed of three parts: an adjusting lock, a movable gear and a fixed gear. The first aluminum alloy climbing section, the second aluminum alloy climbing section and the fixed gear surround the same rotating shaft; and the fixed gear and the first aluminum alloy climbing section Welding and fixing; the movable gear is set on the second aluminum alloy climbing ladder section, and is meshed with the fixed gear through a spring, and one end of the adjustment lock can drive the shaft of the movable gear to move up and down so as to overcome the pressure of the spring to make the movable gear separate from the fixed gear.

The above-mentioned movable gear is located at a distance of 6 cm from the rotating shaft of the second aluminum alloy climbing ladder section.

The two ends of the rotating shaft of the above-mentioned movable gear are arranged in the groove on the second aluminum alloy ladder section, and can move up and down in the groove, and a spring against the movable gear is also arranged on the second aluminum alloy ladder section. The pressure action of the movable gear meshes with the fixed gear.

The present invention has the following beneficial effects:

The right-angle hanging ladder of the multi-purpose safety tool of the present invention adopts a two-stage structure, which can be divided into a climbing ladder and a hanging ladder, and has its use function. The adjustment lock is reliable and the operation is convenient. It can greatly save working time and physical strength in practice. Consumption, improve security. Made of aluminum alloy material, detachable, light in weight, easy to carry and transport.

detailed description

The present invention is described in further detail below in conjunction with accompanying drawing:

Referring to Fig. 1-Fig. 3, the multi-purpose safety equipment right-angle hanging ladder of the present invention comprises a first aluminum alloy climbing ladder section 6 and a second aluminum alloy climbing ladder section 7; the first aluminum alloy climbing ladder section 6 and the second aluminum alloy ladder section The end of the climbing section 7 is connected by an adjustable shaft device 3; the adjustable shaft device 3 is provided with a lock; the outer end of the first aluminum alloy climbing section 6 is provided with a fixed hook 1; the second aluminum alloy climbing section The outer end of 7 is provided with steering hook 2.

The length of the first aluminum alloy ladder section 6 is 3 meters; the length of the second aluminum alloy ladder section 7 is 1 meter.

The adjustable rotating shaft device 3 is composed of three parts: an adjustable lock 5 , a movable gear 8 and a fixed gear 9 , and is a device connecting the first aluminum alloy ladder section 6 and the second aluminum alloy ladder section 7 .

The first aluminum alloy ladder section 6, the second aluminum alloy ladder section 7 and the fixed gear 9 surround the same rotating shaft. And the fixed gear 9 is welded and fixed with the first aluminum alloy ladder section 6, and the two can not rotate relative to each other. The movable gear 8 is arranged on the second aluminum alloy climbing ladder section 7, and the two ends of the rotating shaft of the movable gear 8 are arranged in the groove on the second aluminum alloy climbing ladder section 7, and can move up and down in the groove. The climbing section 7 is also provided with a spring 10 that withstands the movable gear 8 , and the pressure of the spring 10 makes the movable gear 8 mesh with the fixed gear 9 . The adjustment lock 5 is fixed on the second aluminum alloy ladder section 7 through the rotating shaft arranged in the middle, and one end of the adjustment lock 5 can drive the shaft of the movable gear 8 to move up and down so as to overcome the pressure of the spring 10 to make the movable gear 8 Separated from the fixed gear 9; the other end of the adjustment lock 5 is the driving handle.
