In order to achieve the above object, the utility model provides a following technical scheme:
a ladder climbing device comprising: the ladder comprises a ladder stand, a movable door plate, a door lock, a hinge and a positioning device; the ladder stand is installed on the outer surface of the movable door plate, one side of the movable door plate is rotatably connected with one side of a door frame on the machine shed through a hinge, the other side of the movable door plate is fixed with the detachable door frame, the positioning device comprises a concave clamping piece and a convex clamping piece, the convex clamping piece is arranged on the opening and closing side of the door frame, the concave clamping piece is arranged on one side of the movable door plate corresponding to the concave clamping piece, and the convex clamping piece are mutually clamped together when the movable door plate is closed.
Furthermore, the detachable fixing is that the movable door plate is fixed with the door frame through a door lock.
Furthermore, the handrail is arranged on the machine shed above the ladder stand and comprises a left handrail and a right handrail which are respectively arranged on the left side and the right side of the ladder stand, and the height of the upper end of the ladder stand is lower than that of the lower edge of the handrail.
Furthermore, the width of the step of the ladder is not less than 320mm, and the height of the step is not less than 230 mm.
Furthermore, the distance of the handrail exceeding the outer edge of the machine shed in the horizontal direction is larger than the distance of the ladder stand exceeding the outer edge of the machine shed in the horizontal direction.
Further, the number of the positioning devices is not less than two.
Furthermore, a detachable limiting support is further arranged between the movable door plate and the door frame, the two ends of the limiting support are bent, one bending section is inserted into the insertion hole in the bottom of the side face of the door frame, and the other bending section is inserted into the insertion hole in the bottom of the movable door plate.
Has the advantages that: the utility model discloses an install the cat ladder on the dodge gate, saved the space under the condition that does not influence to the cooperation through positioner and handrail has guaranteed the stability of climbing in-process, and easy operation, the climbing is laborsaving.
