Abstract

The invention relates to a hand-lifting door structure. The hand-lifting door structure comprises a door frame and a door plank. The door frame is provided with two door columns and a beam connecting the door columns. The door plank is provided with a handle. Vertical angle iron is fixedly connected to the outer sides of the door columns in the length extending direction of the door columns. One side wall of the angle iron is fixedly connected with the corresponding door column, and a gap is formed between the other side wall of the angle iron and the corresponding door column and movably contains the lifting door plank. Pulleys are arranged at the top ends of the door columns respectively and are provided with slip ropes in a matched mode, one end of each slip rope vertically droops and is fixedly connected with the door plank, the other end of each slip rope is provided with a balancing weight, and the weight of the door plank is equal to the sum of the weights of the balance weights. The angle iron is provided with limiting grooves, the door plank is provided with limiting blocks capable of horizontally sliding along the outer surface of the door plank, and the limiting blocks are in movable fit with the limiting grooves. The side, close to the balancing weight, of each door column is provided with a movable groove, and locking parts are arranged at the bottoms of the movable grooves. The hand-lifting structure is compact and low in cost, and meanwhile the ascending and descending safety of a hand-lifting door is guaranteed.

Description

technical field [0001] The invention relates to a portable door structure, in particular to a portable door structure on an air cooling device in an electrochemical cleaning line. Background technique [0002] Electrochemical cleaning is an effective method to solve residual floating sand in complex castings. After electrochemical cleaning, floating sand often precipitates in the cleaning tank to form waste slag. The residual heat needs to be cooled in the air cooling device for a period of time before it can be transported away. [0003] The air-cooling device in the prior art is often provided with a portable door at the rear for maintenance, inspection and to prevent people below the device from entering by mistake. In order to save space, the portable door is often set in the form of lifting up and down. The safety performance of the door usually requires the purchase of a special lifting door, which is costly. Contents of the invention [0004] The object of the pre...
