Separated combined type plastic crawling ladder for large-scale inspection well

Abstract

The split combined plastic climbing ladder for a large inspection well includes a main body of the inspection well, and the inner wall of the main body of the inspection well is connected to the climbing ladder. The upper part of the convex plate is made with a card hole, and the left and right two connecting plates are connected to the ladder. The ladder includes the main body of the ladder plate. There are clamping plates on the left and right sides of the main body of the ladder plate. There is a card slot between the card plate and the main body of the ladder plate. The card slot matches the convex plate. An elastic card is made in the card plate. There are barbs, and the barbs match the card holes on the protruding plate.

Description

technical field [0001] The invention relates to a plastic climbing ladder, in particular to a split and combined plastic climbing ladder for a large inspection well. Background technique [0002] Inspection wells are drainage auxiliary structures that are set at the intersection, turning, pipe diameter or slope change, water drop, or at a certain distance on straight pipe sections, so that people can regularly check, clean, and dredge the pipes. In order to make it easier for people to enter the buried pipeline through the inspection well, a ladder is installed on the inner wall of the inspection well, and people climb to the lower part of the drainage pipe through the ladder. The ladder of the existing inspection well is usually made of metal materials (such as iron or steel) through welding. It is connected as a whole, which includes straight rods on both sides, and the pedals are welded between the straight rods on both sides. The straight rods are fixed with the inspecti...

Problems solved by technology

In order to make it easier for people to enter the buried pipeline through the inspection well, a ladder is installed on the inner wall of the inspection well, and people climb to the lower part of the drainage pipe through the ladder. The ladder of the existing inspection well is usually made of metal materials (such as iron or steel) through welding. It is connected as a whole, which includes straight rods on both sides, and the pedals are welded between the straight rods on both sides. The straight rods are fixed with the inspection well by fasteners such as screws. After the damage, the whole ladder needs to be replaced, the replacement cost is high, and the installation and disassembly are very troublesome
