Device for facilitating precast yard portal crane to pass through intersection

Abstract

The invention belongs to a device for facilitating a precast yard portal crane to pass through an intersection. The device comprises a picking fork structure and a movable coverage plate structure, wherein the picking fork structure is used for picking up the movable coverage plate which covers the upper end of a portal crane line placement groove to enable the guide line of the portal crane to successfully pass through the lower end of the movable coverage plate; the picking fork structure consists of a connecting bracket, permanent seats, a reinforcement plate, a picking fork and inclined reinforcement rods. The movable coverage plate structure is used for cooperating with the picking fork structure to open and close the upper end surface of the portal crane line placement groove and consists of a fixing bottom plate, a fixed axle lug, a hinge shaft and the movable coverage plate. According to the device, the portal crane can quickly pass through the intersection without stopping, and an iron plate automatically covers the portal crane line placement groove. The device has the advantages of simple and practical structure, labor and time saving, low manufacture cost and good use effect and safety.

Description

technical field [0001] The invention belongs to a device for crossing a crossing for a gantry crane in a precast yard. Background technique [0002] The gantry crane in the prefabrication field is the necessary equipment for the production of the prefabrication field. The gantry crane moves the bottom frame and the rail wheels at the lower end on the track through the crane, and the gantry crane moves the rail wheels on the bottom frame by the crane. Lifting and transporting production materials. The crane, movement and operating system of the gantry crane are all powered by electricity. Usually, a gantry crane wiring ditch is set on the outer side of the track, and the wires leading into the power supply are placed in the gantry crane wiring ditch, which corresponds to the gantry crane wiring ditch. On the mobile chassis of the crane on the side, wire fixing clips are arranged at intervals to fix the wires on the gantry crane. Therefore, the wires at the lower end of the ...

AI Technical Summary

Problems solved by technology

There is a driveway in the precast yard for vehicles to pass through. When the gantry crane line ditch crosses the driveway, an intersection is formed. In order to ensure the smooth passage of vehicles in the driveway, it is necessary to cover the upper end of the gantry crane line ditch that crosses the driveway. However, the iron plate on the upper end of the gantry crane line ditch seriously affects the operation of the gantry crane. When the gantry crane reaches the intersection, it needs to stop. It is time-consuming and labor-intensive, and seriously affects the operation of the gantry crane and traffic safety.
