Problems solved by technology

[0002] Generally, small hexahedron assembled cold storage side-hung doors are equipped with sealing strips around the door, so the four sides must be made of external buckle type, and it is impossible to make a fixed ramp. You can only open the door first and then move the ramp to the door. Remove the ramp to close the cold storage door. Otherwise, the goods in and out of the warehouse cannot be carried by carts, but can only be transported manually. It is very inconvenient and time-...

Abstract

The invention provides a two-section unpowered lifting ramp of a cold storage side-hung door. The two-section unpowered lifting ramp comprises a fixed ramp body and a lifting ramp body. The lifting ramp body is arranged close to the cold storage side-hung door, and the fixed ramp body is located in front of the lifting ramp body. The lifting ramp body comprises a bottom frame, a lifting panel located on the bottom frame, a slide rail groove formed in the bottom frame, a slide rail located in the slide rail groove, wheels located on the lower portion of the lifting panel, a transmission grooved plate and a shifting pin assembly, wherein the transmission grooved plate and the shifting pin assembly are mounted on the upper portion of one side of the slide rail. The bottom frame and the lifting panel are connected through hinges. The slide rail is provided with grooves, a slope is located on one side of each groove, and the grooves correspond to the wheels on the lower portion of the lifting panel in position. The shifting pin assembly is mounted on the lower portion of the cold storage side-hung door. When the cold storage side-hung door is opened, the lifting ramp body slowly rises to the position aligned with the ground in a cold storage along with opening of the cold storage side-hung door, and a carrying vehicle can enter and get out of the cold storage through the ramp for carrying goods. When the door is closed, the lifting ramp body automatically descends, operation is simple, and the situation that the ramp or the cold storage side-hung door is damaged due to the fact that the door is closed when people forget to lower the lifting ramp body is avoided.

Description

technical field [0001] The invention relates to a ramp for a cold storage, in particular to a two-stage non-powered lifting ramp for a side-hinged door of a cold storage. Background technique [0002] Generally, small hexahedron assembled cold storage side-hung doors are equipped with sealing strips around the door, so the four sides must be made of external buckle type, and it is impossible to make a fixed ramp. You can only open the door first and then move the ramp to the door. Remove the ramp to close the cold storage door. Otherwise, the goods in and out of the warehouse cannot be carried by carts, but can only be transported manually. It is very inconvenient and time-consuming to operate each time. However, the general lifting ramp needs to be manually operated after the door is opened. When raising the door, you need to lower the ramp before closing the door. The operation is cumbersome and reduces work efficiency. It is also easy to cause damage to the ramp or the wa...
