Hydraulic engineering overhaul crawling ladder and manufacture method thereof
The invention discloses a hydraulic engineering overhaul crawling ladder. The hydraulic engineering overhaul crawling ladder comprises a first prefabricated steel plate, a second prefabricated steel plate, a first contention piece, a second contention piece and a pedal, wherein the first prefabricated steel plate and the second prefabricated steel plate are located in the same plane and the first prefabricated steel plate, the second prefabricated steel plate and the first contention piece are embedded in the wall; one end of the first contention piece is respectively fixed on the first prefabricated steel plate and the second prefabricated steel plate; two ends of the second contention piece are respectively provided with the external thread; the pedal is provided with two holes through which the second contention piece can pass; the other end of the first contention piece is connected with one end of the second contention piece in a detachable mode; the other end of the second contention piece is connected with the pedal in a detachable mode. Two ends of the second contention piece are respectively provided with the external thread, and connected with the first contention piece and the pedal in a detachable mode, so that the crawling ladder is quickly mounted and dismounted and convenient to overhaul.
