Description of the drawings:
FIG. 1 is a schematic structural diagram of the first embodiment;
FIG. 2 is a schematic structural diagram of a card base according to an embodiment;
fig. 3 is a right side view of fig. 2.
The specific implementation mode is as follows:
example one
Referring to the figures, the engineering ladder for rush repair of the leakage point of the water supply and drainage pipeline comprises a clamping base 1, a ladder frame 3 and a U-shaped inserted bar 6; the clamping base 1 comprises a symmetrical U-shaped clamping base 12, a rotating sleeve 11 and 3 fastening screws 13, the rotating sleeve 11 is welded at the top of the U-shaped clamping base 12, teeth 14 are arranged on the inner wall of one side of the U-shaped clamping base 12, the fastening screws 13 are mounted on the side wall of the other side of the U-shaped clamping base, and the outer ends of the fastening screws 13 are square heads; the ladder frame 3 is formed by welding round pipes and cross beams on two sides, uniformly distributed pin holes 4 are formed in the round pipes, a rotating shaft 2 is welded at the bottom of the round pipes, and two ends of the rotating shaft 2 are installed in the rotating sleeve 11; the U-shaped inserted bar 6 is inserted on the two round tubes of the ladder frame 3 and is limited and fixed by a pin shaft 5 penetrating through the end part of the U-shaped inserted bar 6 and the pin holes 4 on the round tubes; the width between the two side walls of the U-shaped clamping seat 12 is designed in groups according to the model of the pipeline, and the width between the two side walls is larger than the outer diameter of the pipeline; the pin shaft 5 is provided with an R-shaped bayonet lock for clamping; the length of the U-shaped inserted rod 6 is 90 cm; the length of the ladder frame 3 is not less than 1.2 meters.
Taking the leakage point of a pipeline with the outer diameter of 158 mm for emergency repair as an example, selecting a U-shaped clamping seat with a corresponding model, wherein the distance between two side walls of the U-shaped clamping seat is 180-220 mm (most of buried pipelines are externally provided with anticorrosive coatings, so that the actual outer diameter of the buried pipeline is about 170). The height of the U-shaped inserted bar is adjusted according to the depth of the operation pit, for example, the depth of the operation pit is about 2 meters, if the length of the ladder frame is 1.6 meters and the length of the U-shaped inserted bar is 90 centimeters, the U-shaped inserted bar is inserted into a round tube of the ladder frame, the distance between the top end of the U-shaped inserted bar and the top end of the ladder frame is about 60 centimeters, and then a proper pin hole is selected to insert a pin shaft for limiting and fixing. After the operation pit is pumped out, a first emergency repair worker firstly enters the operation pit, or a height-adjusted ladder frame is carefully lowered to the bottom of the pit, the first worker slowly descends into the operation pit from the ladder frame, or a safety rope is used for descending the first emergency repair worker into the pit, or a bucket of an excavator is used for conveying the first worker into the operation pit. After entering the operation pit, a worker clamps a U-shaped clamping seat on the pipeline and screws three fastening screws to clamp the U-shaped clamping seat on the pipeline. Then the rotating shaft at one end of the bottom of the ladder frame is inserted into the rotating sleeve, the rotating sleeve of the other U-shaped clamping seat is sleeved at the other end of the rotating shaft, and finally the U-shaped clamping seat is clamped on the pipeline. Clamping base card is behind the pipeline of operation hole bottom, and the ladder frame can rotate, satisfies the use needs in different slope operation holes. After the engineering ladder is lapped, all rush-repair personnel entering the operation pit can go up and down the operation pit through the stable engineering ladder.
