Rewinding chain lifting drive mechanism for door frame type commercial garage

Abstract

The invention discloses a rewinding chain lifting drive mechanism for a door frame type commercial garage. An electric-driven transverse moving through structure back frame, a truss beam and a rewinding lifting chain are used as novel structural forms for lifting a load bearing main body; spaces in stand columns at the two ends of the electric-driven transverse moving through structure back frameare used as layout forms of chain winding mechanisms for the rewinding lifting chain; meanwhile, a chain winding drive bracket arranged at the tail end of a vehicle platform plate and a drive mechanism thereof are used to perform synchronous chain winding driving on the rewinding lifting chain; a stereoscopic-parked vehicle can cross through the top of the door frame type commercial garage for storage, so that the use level of an uniform warehouse steel structure is reduced, that is, the manufacturing cost is reduced; when a multilayer structural form is implemented, the gravity of a whole transverse moving door frame is lowered to improve the transverse moving stability; and the rewinding chain lifting drive mechanism is more compact and simpler in installation and maintenance, so that the door frame type commercial garage is higher in cost performance and easier to be popularized.

Description

technical field [0001] The invention relates to the field of vehicle warehouse facilities, in particular to a rewinding chain lifting drive mechanism for a portal-type commercial garage. Background technique [0002] It is known that the current gantry-type commercial garage generally adopts a four-point wire rope synchronous hoisting drive mode on the car platform, and its wire rope hoisting drive mechanism and wire rope guide wheel mechanism are all set on the top structure of the overall traversing gantry, in order to overcome the horizontal diagonal force. Concentrated problems The top structure of the overall traversing mast needs to be greatly strengthened, resulting in increased steel usage and cost, and the four sets of hoisting wire ropes need to be set above the top structure of the overall traversing mast, which will cause three-dimensional parking of vehicles The structure that cannot pass through the top of the gantry-type commercial garage for storage will resu...

Problems solved by technology

[0003] In order to overcome the functions of the wire rope hoisting drive mode used in the existing gantry-type commercial garages, the overall traversing gantry needs to adopt an enhanced top stress-bearing structure, which leads to a large amount of steel usage, high cost and multi-layer structure. When the center of gravity of the overall traversing gantry is raised, the stability of the traversing will be reduced. The purpose of the present invention is to provide a rear frame, a truss beam, and a rewinding lifting chain that use an electric drive traversing through structure as a lifting load bearing. The new structural form of the main body also uses the space inside the columns at both ends of the rear frame of the electric drive traverse structure as the layout form of the chain retraction mechanism for the rewinding lifting chain, and at the same time utilizes the chain retraction drive bracket and its drive mechanism at the end of the platform. The rewinding lifting chain is synchronously retracted and driven, and the three-dimensional parking vehicles can pass through the top of the gantry type commercial garage for storage, thereby reducing the use of steel structures in equal warehouses, that is, reducing manufacturing costs and reducing overall horizontal when implementing multi-layer structures. Move the center of gravity of the mast to improve the stability of lateral movement, and adopt the rewinding lifting chain to lift the driving structure to be more compact, and the installation and maintenance are simpler, which can better solve the steel consumption caused by the enhanced top force-bearing structure of the overall lateral movement mast. A rewinding chain hoisting drive mechanism for gantry-type commercial garages that is large, high in cost, and has the problem of reduced traversing stability due to the elevation of the center of gravity of the overall traversing gantry when implementing a multi-layer structure
