Description
Technical Field
[0001] The utility model belongs to the technical field of warehouse cargo stacking equipment, and in particular relates to a telescopic lifting track of a stacking crane. Background Art
[0002] At present, with the development of economy, storage costs are getting higher and higher. In order to make full use of storage space and reduce storage costs, the stacking height of goods in warehouses is getting higher and higher, and the application of high-bay warehouses is increasing. High-bay warehouses generally refer to the use of several layers, dozens of layers or even dozens of layers of shelves to store unit goods. Due to the high height of high-bay warehouses, the corresponding handling and warehousing and warehousing operations must rely on handling equipment.
[0003] At present, the handling equipment used for cargo handling and stacking in warehouses mainly includes forklifts, aisle stackers and stacking cranes. The stacking height of forklifts is generally within 3 meters, which limits the height of cargo stacking and wastes the storage space of warehouses. Moreover, the turning radius of forklifts is large, and sufficient operating space needs to be left between the shelves of warehouses for forklifts, which also wastes the storage space of warehouses. Aisle stackers can only move along the tracks laid in the aisles between the shelves. Not only does it have a large moving stroke and much useless work, it increases energy consumption and is prone to collision. The stacking crane is a lifting track suspended at the lower end of the mobile trolley of the warehouse crane. A load platform equipped with a fork that can move up and down along the lifting track is set on the lifting track. The fork and the load platform are used to realize the movement of goods at the height of the warehouse, and the crane and the mobile trolley are used to realize the movement of goods in the width and length directions of the warehouse, thereby realizing the stacking of goods. For example, the Chinese utility model patent with the patent number "ZL2019217063580" and the name "A stacking crane for a three-dimensional warehouse" discloses a stacking crane that can lift goods. However, when the goods are moved under the drive of the crane, since the lifting track is suspended between the shelves, it is affected by the height of the shelves and the height of the stacked goods, and the lifting track can only move in the aisles between the shelves. Not only does it have a long moving distance and a lot of useless work, which increases energy consumption, but it is also prone to the risk of bumps and collisions. Utility Model Content
[0004] To sum up, in order to overcome the shortcomings of the prior art problems, the utility model provides a telescopic lifting track of a stacking crane, which designs the lifting track suspended at the lower end of the mobile trolley as a telescopic track. When the lifting track moves driven by the stacking crane, the lifting track is retracted to above the shelf so that it is no longer affected by the height of the shelf. This can effectively shorten the moving distance during cargo handling and stacking, reduce energy consumption, and also reduce the risk of collision, thereby ensuring production safety.
[0005] In order to solve the above technical problems, the technical solution of the utility model is implemented as follows:
[0006] A telescopic lifting track of a stacking crane comprises: a fixed track and a movable track, wherein the fixed track is fixedly connected to the lower end of a mobile trolley of the stacking crane, the movable track is located inside the fixed track and can move up and down along the fixed track, and the fork frame of the stacking crane is arranged on the movable track and can move up and down along the movable track.
[0007] Furthermore, it also includes a lifting frame, the upper end of the lifting frame is fixedly connected to the lower end of the mobile trolley, the lifting frame is fixedly connected to the fixed track, and the forks on the fork frame and the lifting frame are respectively located on both sides of the fixed track.
[0008] Furthermore, the lifting frame includes a steel column arranged parallel to the fixed track, an end plate located at the upper end of the steel column and the fixed track, and at least one reinforcing connector connecting the steel column and the fixed track. The fixed track and the steel column are both fixedly connected to the end plate, and the end plate is fastened to the moving trolley.
[0009] Furthermore, when there is one reinforcing connector, the reinforcing connector is located at the lower end of the fixed track; when there are multiple reinforcing connectors, the multiple reinforcing connectors are evenly arranged along the height direction of the fixed track.
[0010] Furthermore, an inclined brace plate connecting the fixed rail and the end plate is provided between the end plate and the fixed rail, and an inclined brace plate connecting the end plate and the steel column is provided between the end plate and the steel column.
[0011] Furthermore, it also includes an intermediate roller, which is located between the fixed track and the movable track. The intermediate roller is tightly connected to the movable track and can roll along the fixed track.
[0012] Furthermore, both upper and lower ends of the movable track are provided with limit stops, and the lower end of the fixed track is also provided with a limit stop.
[0013] Furthermore, the fixed track is a gantry-type fixed track composed of two groove-shaped track openings arranged opposite to each other.
[0014] Furthermore, the movable track is a gantry-type movable track composed of two groove-type track openings arranged opposite to each other, the two groove-type tracks of the movable track are connected by a connecting crossbeam, and the gantry-type movable track is located between the two groove-type tracks of the gantry-type fixed track.
[0015] The beneficial effects of the utility model are:
[0016] The utility model designs the lifting rail suspended at the lower end of the mobile trolley of the stacking crane into a telescopic rail. When the lifting rail moves under the drive of the stacking crane, the lifting rail is retracted to the top of the shelf so that it is no longer affected by the height of the shelf, which can effectively shorten the moving distance when transporting and stacking goods, reduce energy consumption, and also reduce the risk of collision, ensuring production safety. The setting of the lifting frame of the utility model can effectively improve the rigidity of the lifting rail and reduce the swing of the lifting rail caused by excessive height.
