Problems solved by technology

[0003] In order to overcome the problems caused by the deformation of the jaw shaft, the present invention provides a side-opening jaw with a pulley on the frame, and a section of arc-shaped steel rail is buried under the ground below the moving track of the pulley, and the height of the surface of the rail is exactly on the ground. level, so as to ensure the smooth operation of the lead door, reduce resistance, and reduce the tension on the door shaft, so as to prevent the deformation of the door shaft and cause jamming

Embodiment Construction

[0011] Add a steel frame (3) to the free edge of the lead door (2), the frame and the steel load-bearing ribs inside the door are connected to each other to transmit gravity, and a load-bearing pulley (5) is installed below, and the load-bearing pulley (5) moves in the same direction as the door The bottom edge is vertical, so that it is smoother when the door moves, and the weight of the door is shared by the door shaft and the pulley, which reduces the lateral force of the door shaft, and the door shaft is not easy to deform. Along the moving track of the pulley, a section of arc-shaped steel rail (6) is embedded below the ground, and the height of the surface of the steel rail is just at the level of the ground, so that the entry and exit of personnel and vehicles will not be affected.

Abstract

The invention provides a pulley-type vertical hinged lead door.. A rigid frame (4) is additionally arranged on a free edge (3) of a lead door (2); a bearing pulley (5) is arranged below the frame; and a section of arc sliding rail (6) is embedded in the ground of the pulley track. Therefore, the deformation of a lead door shaft (1), caused by the gravity, is avoided.

Description

technical field [0001] The invention relates to a swing door with a pulley. By using the pulley type lead door, the opening resistance of the lead door can be reduced and the door shaft can be prevented from being deformed. Background technique [0002] At present, the weight of the lead door in the accelerator room of the radiotherapy department of the hospital is several tons, and how to ensure its smooth operation is a big problem. Most of them now use sliding rail sliding doors, but this type of door occupies a large area, and the trench of the track needs to be covered by crawlers, thus increasing the chance of failure. There are also some inward-opening type lead doors. The size of the side-opening type lead doors is limited due to the excessive force on the door bearings, so the area can only be made smaller. When the doorway is 120 cm wide, the lead door needs to be 160 cm wide. Wide, so as to ensure a 20cm covering edge around the jaw to prevent radiation from bein...
