Description

Crawling ladder convenient to assemble and used for civil engineering Technical Field The utility model relates to the technical field of crawling ladders, in particular to a crawling ladder convenient to assemble for civil engineering construction. Background In the civil engineering foundation ditch work progress, need set up the cat ladder in the inside of foundation ditch, the staff of being convenient for walks inside entering foundation ditch or walks outside the foundation ditch, prevents that the staff from directly walking on the slope of foundation ditch and taking place to fall down. When placing the cat ladder inside the foundation ditch, because the whole laminating of cat ladder is on the slope of foundation ditch, exists certain angle between the bottom of cat ladder and the foundation ditch soil surface, if there is more grit on the soil surface in the foundation ditch, the bottom of cat ladder slides in the foundation ditch inside taking place by a small margin when probably causing to use the cat ladder, the stability when leading to the cat ladder to use is not high problem. Disclosure of utility model The utility model aims to solve the problem that the stability of a cat ladder is not high during use because the cat ladder is integrally attached to the slope surface of a foundation pit, and a certain angle exists between the bottom end of the cat ladder and the soil surface of the foundation pit, if more sand and stones exist on the soil surface in the foundation pit, the bottom end of the cat ladder can slide in the foundation pit in a small extent during use of the cat ladder, and the cat ladder is convenient to assemble for civil construction. In order to achieve the aim, the utility model adopts the following technical scheme that the crawling ladder convenient to assemble for civil construction comprises a frame body and guardrails, wherein a plurality of supporting rods are fixedly connected to two sides of the top end of the frame body respectively, a plurality of rod bodies capable of being inserted into the supporting rods are arranged on the surface of the guardrails, a plurality of pedals are fixedly connected to the outer surface of the frame body, and two groups of positioning devices capable of further limiting the position of the frame body in a foundation pit are arranged at one end of the frame body. When the ladder stand is used, the frame body is attached to the slope of the foundation pit to enable the support rods of the frame body to face upwards, then a plurality of rod bodies at the bottom end of the guardrail are respectively inserted into the support rods at the top end of the frame body to be assembled with the frame body, after the assembly is completed, a person treads the pedal on the outer surface of the frame body to pass up and down in the foundation pit through the frame body, and after the use is completed, the guardrail is pulled upwards to pull out the rod bodies at the bottom end of the guardrail from the support rods, and then the guardrail can be detached. Preferably, the positioning device comprises a sliding block, one side of the sliding block is rotationally connected with a cylinder, the inner wall of the cylinder is slidably connected with a round rod, the bottom end of the round rod is rotationally connected with a conical rod, a spiral groove is formed in the outer surface of the conical rod, a lug is fixedly connected to one side of the inner wall of the cylinder, the spiral groove on the outer surface of the conical rod is located on the outer side of the lug, sliding grooves are formed in two sides of the frame body respectively, and the sliding block slides on the inner wall of the sliding grooves. The tapered rod is arranged, when the ladder is used, the frame body is placed on the inclined plane of the slope, the two sides of the bottom end of the frame body can respectively push the sliding blocks to move the positions of the sliding blocks and the cylinder in the sliding grooves, then the cylinder is pushed to rotate on one side of the sliding blocks to adjust the angle between the cylinder and the frame body so that the cylinder is approximately perpendicular to the ground of a foundation pit, then the round rod is pushed to slide downwards on the inner wall of the cylinder, the bottom end of the tapered rod is pushed to be inserted into the ground, and meanwhile, the spiral groove on the outer surface of the tapered rod can move outside the protruding block on the inner wall of the cylinder, so that the tapered rod rotates along the direction of the spiral groove, the tapered rod can be inserted into the ground more easily, and the angle between the frame body and the ground of the foundation pit is further limited.
