Description

Power Maintenance Ladder

technical field

The utility model relates to an electric maintenance ladder, which belongs to the field of machinery.

Background technique

Nowadays, the height of utility poles is generally relatively high, and maintenance personnel need to climb to the top of the utility pole to operate during maintenance. The tool usually used is a foot buckle, which is very convenient to use, but the movement is slow, which affects the maintenance process; sometimes a ladder is used, but the ladder One is that the height is not enough, and the other is that it is very inconvenient to transport.

Utility model content

According to the deficiencies in the prior art above, the technical problem to be solved by the utility model is to provide a safe and convenient electric maintenance ladder.

The electric power maintenance ladder described in the utility model comprises a lock ring, a rubber pad is fixed inside the lock ring, two connecting rods are fixed on the lock ring, the connecting rod and the plane where the lock ring are located are at an angle of 45-80 degrees, and the connecting rod is hinged with a soft ladder.

The locking ring consists of a U-shaped rod, the rubber pad is fixed at the bottom of the U-shaped rod, one end of the U-shaped rod is hinged to the sealing rod, the sealing rod and the U-shaped rod form a closed circle, the other end of the U-shaped rod is fixed, and the end of the sealing rod fits on the On the baffle, a rubber pad is fixed on the sealing rod.

The tail end of the sealing rod is connected to the U-shaped rod through a spring, and the sealing rod takes the hinge point as a fulcrum to form a lever, so that the working end of the sealing rod is always in contact with the blocking plate.

A hoop is provided at the lower end of the ladder, and the hoop can be fixed on the utility pole to stabilize the ladder.

Working principle and process:

When working, push the sealing rod into the U-shaped rod to expose the gap of the U-shaped rod, and then move to the utility pole so that the utility rod is placed in the U-shaped rod, loosen the sealing rod, and the sealing rod resets under the action of the spring force. Confine the pole to the circle formed by the U-shaped pole and the sealing pole, send the U-shaped pole to the top of the pole through the long pole, pull down the soft ladder to make the rubber pad contact with the pole, and fix it on the pole by friction, the soft ladder The lower end is fixed on the utility pole through the hoop, and then maintenance personnel climb to the maintenance point along the soft ladder for maintenance.

Compared with the prior art, the utility model has the following beneficial effects:

The electric power maintenance ladder described in the utility model has simple structure, convenient operation, the soft ladder can reduce the volume, is convenient for transportation, and has high safety factor.

Detailed ways

Embodiments of the utility model are further described below in conjunction with the accompanying drawings:

As shown in Figure 1 and Figure 2, the electric maintenance ladder described in the utility model includes a lock ring, a rubber pad 1 is fixed inside the lock ring, and two connecting rods 4 are fixed on the lock ring, and the connecting rod 4 and the plane where the lock ring is located are in the shape of 45-80 degree angle, hinged soft ladder 5 on connecting rod 4.

The lock ring includes a U-shaped rod 3, the rubber pad 1 is fixed at the bottom of the U-shaped rod 3, one end of the U-shaped rod 3 is hinged to a sealing rod 7, and the sealing rod 7 and the U-shaped rod 3 form a closed circle, and the other end of the U-shaped rod 3 is fixed. Sheet 9, sealing rod 7 end fits on the catch 9, and rubber pad 1 is fixed on the sealing rod 7.

Sealing rod 7 tail end is connected U-shaped bar 3 by spring 8, and sealing rod 7 is fulcrum to form lever with hinge point, makes sealing rod 7 working ends contact with catch 9 all the time.

The lower end of the soft ladder 5 is provided with a hoop 6, and the hoop 6 can be fixed on the utility pole 2 to play the role of stabilizing the soft ladder 5.

Working principle and process:

When working, push the sealing rod 7 in the U-shaped rod 3 to expose the gap of the U-shaped rod 3, and then move to the utility pole 2, so that the utility rod 2 is placed in the U-shaped rod 3, unclamp the sealing rod 7, and the sealing rod 7 Reset under the force of the spring 8, limit the utility pole 2 in the circle formed by the U-shaped pole 3 and the sealing pole 7, send the U-shaped pole 3 to the top of the utility pole 2 through the long pole, pull down the soft ladder 5 to make the rubber pad 1 Contact with the utility pole 2, and be fixed on the utility pole 2 by friction force, the lower end of the soft ladder 5 is fixed on the utility pole 2 by the hoop 6, and then the maintenance personnel climbs along the soft ladder 5 to the maintenance point for maintenance.
