Description

Technical Field

[0001] This utility model relates to the field of automated warehouse outbound technology, and in particular to a forklift mechanism with lifting function. Background Technology

[0002] Automated storage and retrieval systems (AS / RS) are widely used by major equipment manufacturers. The manual working conditions involve using forklifts to lift and transfer heavy palletized materials out of the AS / RS to designated locations, resulting in long working hours and low automation in factories.

[0003] Currently, due to the height limitation of the first layer of the stacker crane when picking up materials from the automated storage and retrieval system (AS / RS), lifting equipment is needed to reduce the height of heavy palletized materials from the ground, making it easier for manual transfer to designated workstations. Otherwise, there is a technical problem that the heavy palletized materials leaving the AS / RS are too high from the ground, making it inconvenient for manual transfer to the production line, which reduces production efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a forklift mechanism with lifting function. This forklift mechanism with lifting function effectively solves and reduces the technical problem of heavy pallet materials being too high off the ground when leaving an automated warehouse, making it inconvenient to manually transfer the materials to the production line. It reduces the difficulty of manual forklift handling, and has a simple structure that is easy to maintain, ultimately achieving the goals of reducing production costs and improving production efficiency.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a forklift mechanism with lifting function, comprising a mechanism frame, an inverted trapezoidal telescopic fork fixing base with a centrally located groove installed at the center of the bottom surface of the mechanism frame, a telescopic fork installed at the center of the groove bottom surface of the telescopic fork fixing base, lifting components symmetrically installed on both sides of the telescopic fork fixing base, guide posts inserted into holes at the four corners of the telescopic fork fixing base, a guide post fixing beam connected between the two end frames of the mechanism frame, the upper end face of the guide post being fixedly connected to the guide post fixing beam, and its lower end face being fixedly connected to the bottom surface of the mechanism frame.

[0008] Furthermore, each of the lifting components includes a commutator base and a lifting platform base mounted on the bottom surface of the mechanism frame and located on one side of the telescopic fork fixing base. A bevel gear commutator is mounted on the commutator base, and the left and right sides of the bevel gear commutator are respectively connected to a drive shaft via couplings.

[0009] Furthermore, the upper end face of the lifting screw is fixedly connected to the guide column fixing beam.

[0010] Furthermore, holes are made at the four corners of the telescopic fork fixing base and next to the guide post to fix the lifting nut in them. The lifting nut moves up and down on the lifting screw, thereby driving the telescopic fork fixing base to move up and down.

[0011] Furthermore, there is one commutator base located on one side of the telescopic fork fixed base, and two elevator bases.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 A forklift mechanism with lifting function includes a mechanism frame 1. A telescopic fork fixing base 2 with an inverted trapezoidal shape and a central groove is installed at the center of the bottom surface of the mechanism frame 1. A telescopic fork 3 is installed at the center of the bottom surface of the groove of the telescopic fork fixing base 2. Lifting components 4 are symmetrically installed on both sides of the telescopic fork fixing base 2. Guide posts 5 are inserted and installed through holes at the four corners of the telescopic fork fixing base 2. Guide post fixing beams 6 are connected between the two end frames of the mechanism frame 1. The upper end face of the guide post 5 is fixedly connected to the guide post fixing beam 6, and its lower end face is fixedly connected to the bottom surface of the mechanism frame 1.

[0022] In the above embodiments, each lifting assembly 4 includes a commutator base 401 and a lifting platform base 402, which are installed on the bottom surface of the mechanism frame 1 and located on one side of the telescopic fork fixing base 2. There is one commutator base 401 located on one side of the telescopic fork fixing base 2, and there are two lifting platform bases 402. The commutator base 401 is installed in the middle position on the mechanism frame 1, and the two lifting platform bases 402 are symmetrically installed on both sides of the commutator base 401. A bevel gear commutator 403 is installed on the commutator base 401. The left and right sides of the bevel gear commutator 403 are respectively connected to the drive shaft 405 through the coupling 404. The outer side of the bevel gear commutator 403 is connected to the drive shaft 405. A servo motor 407 is connected to a planetary reducer 406. A screw jack 408 is installed on the lifting platform base 402. The other end of the drive shaft 405 is connected to the screw jack 408. The screw jack 408 includes an upwardly oriented lifting screw 409. A lifting nut 410 is fitted onto the lifting screw 409. The upper end face of the lifting screw 409 is fixedly connected to the guide column fixing beam 6. Holes are opened at the four corners of the telescopic fork fixing base 2, next to the guide column 5, to fix the lifting nut 410. The lifting nut 410 moves up and down on the lifting screw 409, thereby driving the telescopic fork fixing base 2 to achieve the lifting movement.

[0023] The working principle of the above embodiments is as follows:

[0024] In operation, the lifting components 4 on both sides of the telescopic fork mounting base 2 begin to operate. First, the servo motor 407 starts, transmitting power through the planetary reducer 406 to the bevel gear commutator 403. The bevel gear commutator 403 drives the drive shafts 405 on both sides to rotate, which in turn drives the screw jack 408. This causes the lifting nut 410 to lift the telescopic fork mounting base 2 on the lifting screw 409. During the ascent, the telescopic fork mounting base 2 simultaneously rises along the guide column 5, making the movement more stable. The lifting speed is controlled by a frequency converter. When the designated height is reached, a proximity switch connected to a sensor sends a signal to stop the ascent. At this point, the forks of the telescopic fork 3 begin to work. After precise positioning, as the forks approach the target goods, the multi-section fork arms extend section by section until they completely cover the bottom of the goods. After grabbing the goods, the forks retract, removing the goods from their original position. Subsequently, the forks transport the goods to the target location according to instructions and, through precise positioning, move the goods to the designated workstation. The telescopic fork 3 used here is a mature standard outsourced component, and its structure will not be described in detail here.
