Detailed Description
As shown in fig. 1 to 5, a detachable telescopic vertical ladder for an equipment manhole is composed of a ladder frame 1, a ladder beam 2 and quick-release bolts 10, wherein:
an inspection well: two clamping frames 5 are transversely arranged on the well wall at the upper end in the inspection well at intervals, the inner ends of the clamping frames are fixed on the well wall 6 of the corresponding part, and fixing through holes are correspondingly arranged on two sides of the outer ends of the clamping frames. Two magnetic suction frames 8 are transversely arranged on the well wall at the middle part and the lower end of the inspection well at the lower end of the clamping frame at intervals. The inner end of the magnetic suction frame is fixed on the well wall of the corresponding part, the outer end of the magnetic suction frame is provided with a magnetic box 12, and the box opening of the magnetic box is outward. The periphery of the box cover 11 is fixed on the edge of the magnetic box at the periphery of the box opening through screws 14, and the box cover is used for conveniently taking and placing the permanent magnet blocks and sealing the magnetic box. The magnet placing box is internally provided with a permanent magnet block 13.
Step frame 1: a plurality of ladder beams are fixed between the inner sides of two angle steel columns which are arranged side by side in a staggered manner at intervals from top to bottom to form a ladder frame. The upper ends of the outer sides of the angle steel columns corresponding to the two clamping frames are provided with clamping lug frames 7, the two sides of the outer ends of the clamping lug frames are correspondingly provided with connecting through holes, and the quick-release bolts sequentially penetrate through the fixing through holes in the clamping frames and the connecting through holes in the clamping lug frames to fix the ladder frames on the clamping frames. Otherwise, the seat ladder frame can be separated from the clamping frame. The quick-release bolt is a product purchased in the market. The inside wall of the corner steel column outside the ladder beam is longitudinally provided with a clamping slide rail 9, and the outer sides of the lower ends of the corner steel columns corresponding to the two magnetic suction racks on the middle well wall are provided with suction plates 15. The suction connection plate is a plane rectangular iron plate.
The telescopic ladder frame 4: the telescopic ladder frame is positioned between the inner sides of the two corner steel columns of the seat ladder frame. A plurality of ladder beams are fixed between the inner sides of two angle steel columns which are arranged side by side in a butt joint mode at a certain distance from top to bottom at intervals to form a telescopic ladder frame. And clamping sliding grooves 3 are longitudinally arranged on the outer sides of two corner steel columns of the telescopic ladder frame corresponding to the clamping sliding rails of the seat ladder frame. The clamping sliding grooves are slidably clamped on the clamping sliding rails, so that the telescopic ladder frame is slidably matched with the inner sides of the two corner steel columns of the seat ladder frame.
