Description

a shaft ladder

technical field

The utility model relates to a ladder, in particular to a shaft climbing ladder.

Background technique

When working in a shaft, it is necessary to install a ladder. The existing ladder is inconvenient to install, and the protection for the operators in the shaft is insufficient. When danger occurs, the operator has nowhere to hide.

Contents of the invention

The purpose of the utility model is to propose a climbing ladder which can ensure the safety of operators in the shaft.

In order to achieve the above purpose, the following technical solutions are provided:

A vertical shaft ladder, comprising two vertical bars arranged in parallel, the two vertical bars are fixedly connected by a plurality of sets of horizontal bars arranged in parallel; each set of horizontal bars is composed of two horizontal bars, and one of them One side is fixedly connected, and the other is fixedly connected with the other side of the two vertical bars; multiple arc-shaped guardrails are fixed on one side of the two vertical bars, and multiple sets of double-row guardrails are fixed on the other side of the two vertical bars. Anchor rods; a rest platform is fixedly arranged in the middle of the two vertical rods, and the rest platform and the double row of anchor rods are respectively on both sides of the two vertical rods. The installation can be completed by inserting the anchor rod into the pre-drilled hole on the cave wall, and the installation is simple; the curved guardrail can avoid the danger of the staff falling during the climbing process, and effectively protect the personal safety of the staff; the rest platform It can provide rest for the staff, and can also be used as an escape platform when danger occurs, reducing the danger of the staff during work.

Preferably, the number of the cross-bar group is the same as that of the arc-shaped guardrail, one cross-bar group and one arc-shaped guardrail form a group, and the cross-bar and the arc-shaped guardrail in one group are on the same horizontal plane.

Preferably, the rest platform includes a flat plate, and one side of the flat plate is provided with a groove with the same shape as the curved guardrail, and the side of the flat plate with the groove is fixedly connected with two vertical bars, and the edge tops of the remaining three sides are fixedly arranged fence.

Preferably, the guardrail includes a plurality of uprights, the bottom ends of the uprights are fixedly connected to the tops of the slabs, and the tops of the uprights are fixedly connected through crossbeams.

Further, it also includes a top wall rod, the top wall rod is fixedly connected with two vertical rods; the top wall rod and the double-row anchor rods are on the same side of the two vertical rods, and the length of the top wall rod is shorter than the length of the double-row anchor rods. Because the cave wall is not smooth, there will be some protruding stones and other objects. The top wall rod keeps a certain distance between the ladder and the cave wall to avoid scratching the staff by the stones and other objects on the surface of the cave wall.

Further, a reinforcement rod is also included, and the reinforcement rod is fixedly connected with the arc-shaped guardrail away from the vertical rod. Increase the strength of the ladder and improve its stability.
