Abstract

The invention discloses an improved embedded trolley frame of a double-girder crane. The improved embedded trolley frame of the double-girder crane comprises a frame body, wherein the frame body is formed by connecting two U-shaped trolley plates; sides of bottoms of the two trolley plates extend upwards to form projections; girder trolleys are mounted at two ends of each projection; a connecting hinge pin which is connected with an electric chain hoist is arranged in the upper end of the frame body; a control instrument is fixedly arranged in the frame body; a weight sensor is mounted in the control instrument; an infrared detector is arranged at the lower end of the control instrument; and the control instrument is connected with an external power supply. The improved embedded trolley frame of the double-girder crane can stably support a load well owing to a double-girder structure of the improved embedded trolley frame, swinging of the load can be minimized in a hoisting process, and therefore, when the hoisted weight is quite large in size or is required to be clamped by a clamp, a double-girder embedded trolley is a good choice.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to an improved double-girder crane embedded trolley frame. Background technique [0002] In the actual application environment of cranes, we often encounter such a situation: the headroom of the factory building is limited, and the height of every centimeter is very important. In some special working conditions, even the height of every millimeter has a great influence on the effective lifting. It is crucial. For example, in some factories' offices, basements, coordinate measurement rooms and laboratories, etc. For this special use environment, it seems impossible to achieve an effective lifting height, and the existing double-girder crane embedded trolley frame is not installed with an overweight limiting device, often due to the load carried by the double-girder crane embedded trolley frame. Crane damage due to heavy cargo. Contents of the invention [0003] In order to over...
