Description

Technical Field

[0001] The utility model belongs to the technical field of logistics equipment, and specifically relates to a lifting rail for a stacker. Background Art

[0002] A stacker is the main hoisting and conveying equipment in an automated warehouse, being a special hoisting mechanical device developed along with the development of automated warehouses. Warehouses using such equipment can reach a maximum height of 40m, and most of them are between 10m and 25m. The main purpose of the stacker is to shuttle back and forth in the aisles of the automated warehouse, store the goods located at the aisle opening into the storage slots, or take the goods out of the storage slots and transport them to the aisle opening. This type of equipment can only operate inside the warehouse, and other equipment is required to allow goods to enter and exit the warehouse.

[0003] The load carriage of the stacker moves vertically up and down on the lifting guide rail, and a guiding device needs to be provided to limit the shaking of the load carriage in the horizontal transverse direction and the horizontal longitudinal direction. The existing guiding device for the load carriage of the stacker includes an upper guiding wheel set and a lower guiding wheel set which are symmetrically arranged on two sides of the frame of the load carriage along the lifting guide rail. The upper guiding wheel set and the lower guiding wheel set each independently include a horizontal transverse guide wheel whose rolling surface substantially abuts against the outer side surface of the lifting guide rail, and a horizontal longitudinal guide wheel whose rolling surface abuts against the top base plate of the lifting guide rail, which is the basic function of the lifting guide rail.

[0004] In addition, due to the structural characteristics of the single-column stacker, the lifting guide rail and the safety gear guide rail share the same rail. Since the safety gear and the rail need to ensure sufficient friction to reduce the braking distance, anti-rust oil cannot be applied on the rail, which easily causes the rail to rust, and in turn affects the service life of both the rail and the guide wheels. Contents of the Utility Model

[0005] In order to overcome the above difficulties and realize the functions of guiding and safety gear on a single rail at the same time, the utility model designs a stacker lifting rail, and the technical solution is as follows.

[0006] A lifting rail for a stacker, the cross section of the rail is in a shape of "convex", the bottom of the rail is connected to the column of the stacker, the first step at the root of the "convex" shaped cross section is the clamping surface for the safety gear, and the second step at the upper part is the guiding surface for the guide wheels of the load carriage.

[0007] Further, the rails are respectively arranged on both sides of the column, and are opposite to each other in position.

[0008] Further, a safety gear is arranged on the outer side of the first step at the root.

[0009] Further, no lubricating layer is provided on the first step at the root.

[0010] Further, the load carriage of the stacker is provided with a plurality of sets of guiding wheels, and each set is provided with three guiding wheels.

[0011] Preferably, the three guide wheels are in contact with two sides and the top of the upper second step in three directions respectively.

[0012] Preferably, a lubricating layer is provided on the contact surface.

[0013] Compared with the prior art, the present utility model has the following beneficial effects: (1) The present utility model designs a guide rail with a "convex"-shaped cross section, which can separate the lifting guide rail surface from the safety gear clamping surface to realize different functions; (2) The guide surface of the guide rail of the present utility model can be periodically coated with anti-rust oil to prolong the service life of the rail and the guide wheels; (3) The clamping surface of the guide rail of the present utility model is kept dry to provide sufficient friction force and reduce the forced braking distance when the loading platform falls. Brief Description of the Drawings

[0014] Figure 1 is a schematic diagram of the rail cross section of the present utility model; Figure 2 is a schematic installation diagram of the rail and the stacker loading platform of the present utility model.

[0015] Wherein, 1 is a column, 2 is a rail, 3 and 4 are first steps / clamping surfaces, 5, 6 and 7 are second steps / guide surfaces, 8 is a guide wheel, 9 is a loading platform, and 10 is a safety gear. Detailed Description of the Preferred Embodiments

[0016] The technical solution of the present utility model will be further explained below with reference to the accompanying drawings.

[0017] As Figure 2 shown, a stacker lifting rail has a "convex"-shaped cross section, the bottom of the rail 2 is connected to the stacker column 1, the first steps 3 / 4 at the root of the "convex"-shaped cross section are safety gear clamping surfaces, and the upper second steps 5 / 6 / 7 are guide surfaces for the guide wheels of the loading platform.

[0018] As Figure 1 shown, the rails 2 are respectively disposed on two sides of the column 1 and are opposite in position. A safety gear is disposed on the outer side of the root first steps 3 / 4. The loading platform of the stacker is provided with several groups of guide wheels 8, and each group is provided with three guide wheels 8. The three guide wheels 8 are in contact with the three directions 5 / 6 / 7 on both sides and the top of the upper second step respectively.

[0019] No lubricating layer is provided on the clamping surfaces 3 / 4. Due to functional requirements, these two surfaces need to be kept dry to provide sufficient friction force.

[0020] The guide surfaces 5 / 6 / 7 are provided with a lubricating layer. To prevent rust, these three guide surfaces can be periodically coated with anti-rust oil.

[0021] The above technical solutions can separate the lifting guide rail surface from the safety clamping surface. The guide surface can be regularly coated with anti-rust oil to improve the life of the rail and guide wheel. The clamping surface can be kept dry to provide sufficient friction and reduce the distance of forced braking when the loading platform falls.
