Description

Technical Field

[0001] The utility model relates to the technical field of double-layer lifting doors, and particularly relates to a double-layer lifting door for an integral moving spray booth. Background Technique

[0002] In modern industrial production, as a key device, the opening and closing mode of the inlet and outlet of a spray booth directly affects production efficiency and operation convenience. Most traditional spray booth doors are of a single structure, and their opening and closing often occupy a large space and are complex to operate. When spraying and drying large-sized workpieces in an integral moving spray booth, the spray booth needs to have a large door opening to enable the workpieces to enter and exit between the moving spray booths. When the door opening is large, a relatively high lifting door is required to achieve the airtightness of the spray booth. Usually, the lifting door needs twice its own height of space to fully open the door opening. In many cases, after the lifting door reaches this height, it will interfere with the factory overhead crane.

[0003] Moreover, in the application document with the publication number CN219356686U, a double-layer lifting door for an integral moving spray booth is mentioned. When spraying or drying large workpieces, by starting the electric hoist, the lower lifting door is driven to move upward. When the lower lifting door moves upward to contact the stop block, if the lower lifting door continues to move upward, the upper lifting door will follow the lower lifting door to move upward synchronously, so that the corresponding opening is fully opened, preventing interference with the factory overhead crane. However, there are still certain defects that need to be optimized. The specific defects are as follows: The stability and flexibility of the door body during the lifting process need to be improved.

[0004] Therefore, it is particularly important to design a double-layer lifting door for an integral moving spray booth to change the above technical defects and improve the overall practicality. Content of the Utility Model

[0005] The purpose of the utility model is to provide a double-layer lifting door for an integral moving spray booth to solve the problems raised in the above background technique.

Mounting holes are provided inside the first hooks and the second hooks, and the first ropes and the second ropes are mounted and connected to the mounting holes.

[0011] As a preferred solution of the present utility model, the first ropes and the second ropes are made of stainless steel wire ropes.

[0012] As a preferred solution of the present utility model, sliders for adapting to the sliding grooves are provided at both ends of the lower hanging door to assist the sliding connection between the lower hanging door and the upper hanging door.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, by providing a double-layer lifting door for an integral moving spray booth, using the structures of the fixed frame, gear racks, gears, drive motors, hoists, and hanging doors, the second hoist is used to raise the lower hanging door, and in cooperation with the sliding grooves and the sliders, a semi-open form is achieved; then the first hoist and the drive motor are started to drive the upper hanging door to rise, achieving a fully open form.
