Detailed Description
The utility model will be described in detail below with reference to the drawings and the detailed description.
The utility model provides a special hard hanging ladder for the internal operation of a container, as shown in fig. 1 and 2, the special hard hanging ladder comprises a steel circle 1 placed on a manhole flange at the top of a tank, wherein the steel circle 1 can be adjusted according to the manhole elevation angle at the top of the container, but a positioning clamping groove 2 is required to be completely clamped into the outer edge of the manhole, otherwise, potential safety hazards exist, and the positioning clamping groove 2 is arranged at the bottom of the steel circle 1, the inner diameter of the positioning clamping groove 2 is required to be 3-5 mm larger than the outer diameter of the manhole flange, the height of the clamping groove is required to be kept at 40-60 mm, so that the steel circle can be ensured not to be shifted, and the steel circle can be conveniently disassembled;
a pair of steel sleeves 3 which are parallel to each other and have apertures on a horizontal line are arranged at the 1/3 circumference position of the steel circle 1, a gap between the two steel sleeves 3 can be respectively arranged at the hanging rings 5 at the top ends of the hard hanging ladders 4, the steel sleeves 3 and the hanging rings 5 are respectively connected by bolts 6, one end of each bolt 6 is provided with a clamping table 8, the other end of each bolt is provided with a riveting hole 9 for preventing accidents caused by disengagement, a foldable and elastic supporting rod 7 is respectively arranged at the two ends of the hard hanging ladders 4, which are close to the bottom end by about 100mm, the length of each supporting rod 7 is equal to the distance between the hard hanging ladders 4 and the container wall after being arranged, the supporting rods 7 can be folded for convenient storage, the hard hanging ladders 4 can be arranged into a plurality of sections, each section of the hard hanging ladders 4 can be freely planned according to the top space of the container and the weight of the hanging ladders, the steel sleeve A arranged at the bottom end of each section of the hard hanging ladders 4 is connected with the hanging rings 5 arranged at the top ends of the previous section of the hard hanging ladders 4, and thus the length of the folding ladders can be repeatedly increased according to the working conditions on site;
when a person needs to enter the container for operation, firstly, the lowest section of the hard hanging ladder 4 is folded and unfolded, meanwhile, the supporting rods 7 are folded and unfolded to form a right angle with the hard hanging ladder 4, the unfolded section of the hard hanging ladder 4 is placed in a manhole, then the section of the hard hanging ladder 4 is unfolded in sequence, finally, the steel circle 1 is embedded in the manhole, the steel sleeve 3 is connected with the hanging ring 5 at the top end of the hard hanging ladder 4 through the bolts 6, and the container operation can be carried out after the hanging ladder is adjusted to be vertically downward;
benefit analysis: the PVC device 8 polymerization kettles need to be cleaned once every 4 months, a rope ladder is used for the original operation of entering and exiting, an operator climbs up and down to keep the body balanced, the gravity center is upward, the operator mainly depends on arm strength to move up and down, once the operator is tired, the operator uses the arm to feel weak, the gravity center moves down, and the operator is unbalanced; the simple steel hard ladder cannot be applied due to the factors of limited space, oversized container and the like, so the hard hanging ladder for the cleaning kettle is designed. The kettle cleaning time can be saved by 1 hour each time, and the feeding is advanced. 1 hour by 8 days by 12 months/4 months=24 hours (one year can save time)/8 hours (polymerization time per kettle material) =3 kettle materials by 13.5 (tonnage per kettle material) =40.5 tons of PVC, 40.5 tons of PVC can be produced more each year, and the operation safety of operators can be ensured.
