Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

FIG. 1 is a schematic view of a perspective structure of the present invention; FIG. 2 is a schematic view of another perspective structure of the present invention; as shown in fig. 1-2, a hydraulic engineering overhauls cat ladder includes: the movable ladder comprises a fixed ladder and a movable ladder, wherein the fixed ladder is in sliding connection with the movable ladder, in the embodiment, the sliding connection between the fixed ladder and the movable ladder is mainly realized through the sliding between a fixed ladder longitudinal beam 1 and a movable ladder longitudinal beam 2, specifically, the movable ladder longitudinal beam 2 is inserted into a longitudinal sliding groove formed in the fixed ladder longitudinal beam 1, a movable ladder cross beam 8 and a fixed ladder cross beam 7 are staggered front and back to ensure the flexibility smoothness, a stabilizing seat 5 is hinged to the lower end of the fixed ladder longitudinal beam 1, and a ground binding screw 6 is vertically and downwards arranged on the stabilizing seat and used for screwing the ground binding screw 6 into the ground after the inclination angle of the ladder is adjusted so as to play a role in stabilizing;

there is card pipe assembly at the upper end fixed mounting of escalator longeron 2 for the joint is on water conservancy pipeline, and in this embodiment, card pipe assembly 3 has 2 settings, and installs respectively in the upper end of two longerons of escalator, and card pipe assembly 3 includes (refer to fig. 3): the upper semicircular hook piece is fixedly welded at the upper end of the movable ladder longitudinal beam 2, the lower semicircular hook piece is detachably connected with the upper semicircular hook piece, and the detachable connection is mainly realized by a bolt assembly 303 penetrating through mounting holes formed in the upper semicircular hook piece 301 and the lower semicircular hook piece 302;

a locking mechanism 4 is further provided on the fixed ladder and the movable ladder for restricting and unbinding the relative displacement between the fixed ladder and the movable ladder, and in this embodiment, the locking mechanism 4 includes: locking screw 401, separation blade 403 and nut 402 have seted up the high gear position regulation hole of a plurality of equal aperture sizes respectively on movable ladder longeron 2 and fixed ladder longeron 1, include respectively: in the embodiment, 12 holes are formed in a single-side single beam, so that 48 holes are formed in the movable ladder longitudinal beam 2 and the fixed ladder longitudinal beam 1, and the positions of the holes need to be staggered with the arrangement positions of the fixed ladder transverse beam 7 and the movable ladder transverse beam 8, so that a sufficient passing space is provided for a locking screw rod; so locking screw 401 transversely passes fixed ladder in proper order and keeps off position regulation hole 101, the activity ladder keeps off position regulation hole 201 and fixed ladder and keeps off position regulation hole 101 to establish respectively at locking screw's both ends with the separation blade, the nut respectively with locking screw's both ends threaded connection, with this purpose that reaches the locking, when needs are relieved the restraint, only need loosen the nut take out locking screw can, its fixity and stability of this kind of locking mode are good, difficult skidding.

The using method comprises the following steps: firstly, the lower semicircular clamping piece 302 of the clamping pipe assembly is dismounted, meanwhile, the locking mechanism 4 is dismounted, then the movable ladder is pulled out, the upper semicircular hook piece 301 is hooked on the water conservancy pipe, then the fixed ladder is pulled to a proper angle, then the ground binding screw is screwed into the ground for fixing, then the locking screw 401 transversely penetrates through the fixed ladder gear adjusting hole 101, the movable ladder gear adjusting hole 201 and the fixed ladder gear adjusting hole 101 in sequence, blocking pieces are sleeved at two ends of the locking screw respectively, nuts are in threaded connection with two ends of the locking screw respectively, then an operator takes the bolt assembly 303 and the lower semicircular clamping piece 302 to climb to the height of the water conservancy pipe 9, and the bolt assembly 303 and the lower semicircular clamping piece 302 are mounted on the upper semicircular clamping piece 301 to achieve the final fixing purpose.
