Ultimate headroom plate heat exchanger lifting device

Abstract

The invention relates to a lifting and positioning device for a plate type heat exchanger in a space with limit height. The device is structurally characterized in that a base is composed of two equilong steel frames, wherein each frame is manufactured through equilong I-shaped steel or two channel steel by back-to-back welding; sleeves are welded above two ends of each steel frame; two front vertical columns are inserted into two sleeves in front of the two steel frames of the base while two rear vertical columns are inserted into two sleeves at the back of the two steel frames of the base; sleeves are welded to two ends of a movable ejector rob, respectively, wherein the movable ejector rob sleeves the two front vertical columns through the sleeves at two ends and can slide up and down on the two front vertical columns; two first lugs are welded to the movable ejector rob; a second lug is welded to the top part of each front vertical column; a third lug is welded onto each rear vertical column; a traction hanger is arranged at a part, connected with the base, between the two front vertical columns. The device is movable and detachable and can be recycled; the plate type heat exchanger is lifted from the bottom part, and thus the problem that the plate type heat exchanger cannot be positioned to a foundation from the upper part within the height limited space can be solved.

Description

technical field [0001] The invention relates to a lifting and positioning device for a plate heat exchanger with a limit clearance, which is applied in the process of placing a plate heat exchanger in construction engineering, and solves the problem that the plate heat exchanger cannot be moved from the ground due to the low clearance of the equipment layer (or due to the existence of an interlayer). The problem of lifting the upper part into place. Background technique [0002] In high-rise and super high-rise construction projects, the headroom of the electromechanical equipment floor is not high, or when the plate heat exchanger is located on the foundation due to the interlayer, the top space is very small. In this case, the plate heat exchanger cannot be installed. According to the general method, lift from the top and exceed the height of the foundation to complete the placement. Therefore, a special lifting device is used to lift the plate heat exchanger into place f...
