The invention discloses a hand cranking type movable cover plate for a hoisting hole in a production workshop and a utilization method of the hand cranking type movable cover plate. A hoisting component comprises a vertical rod, a fixed pulley, a hand cranking winch and a steel wire rope. The vertical rod is erected on an outer base layer of the hoisting hole, the fixed pulley is arranged at the top of the vertical rod, the hand cranking winch is arranged in the middle of the vertical rod, and one end of the steel wire rope is pulled out from the hand cranking winch and then fixed to a hangingring on a first cover plate. A folding cover plate component comprises a folding cover plate and an angle iron frame arranged along the edge of the hoisting hole, the edge of the folding cover platecovers the angle iron frame to close the hoisting hole, the other end of the steel wire rope is fixed to the folding cover plate, and the hand cranking winch is capable of pulling up the folding coverplate through the steel wire rope to uncover the hoisting hole. By arrangement of the angle iron frame at the hoisting hole, on the one hand, the folding cover plate can be supported, and on the other hand, a rail can be provided for a roller of the folding cover plate in traveling, the folding cover plate can be closed smoothly, manual transporting of the cover plate is avoided, and safety and convenience in use are improved.
Description
technical field [0001] The invention belongs to the field of building construction, and in particular relates to a hand-operated movable cover plate for a hoisting hole in a production workshop and a method for using the same. Background technique [0002] In the production workshop, there are some hoisting holes for hoisting objects on the upper and lower floors. These hoisting holes are covered with cover plates when not in use, and the cover plates are removed when in use. Temporary safety protection railings are set around the hoisting holes and are not firm. Bring many safety hazards to maintenance personnel. Some cover plates are divided into two parts and are fixed on both sides of the hoisting hole with hinge shafts. When opening such cover plates, the operator has to operate many times to complete the process of opening the cover plate, which brings a lot of inconvenience to the operators. Some are equipped with fixed safety railings around the hoisting holes, and ...
