Description

Technical Field

[0001] The utility model relates to the technical field of transporting and lifting, in particular to a chain-type two-stage linkage lifting device based on a chassis robot. Background Art

[0002] As the automation integration of smart warehousing and smart factories becomes higher and higher, the degree of manual operation and participation is becoming smaller and smaller. At present, the participation of smart mobile robots is becoming more and more. Unmanned warehouses such as vertical warehouses and archives require smart robots to automatically store and retrieve in order to improve the utilization rate of warehouse space and the passability of the robot body. Warehouse frames are generally designed to be relatively high, and robots have to improve the storage and retrieval mechanism to meet the needs of high-altitude storage and retrieval. The doors between warehouses and floor elevator doors are relatively low, and the chassis of the robot body cannot be too high to meet the needs of robot passability during operation.

[0003] At present, the shortcomings of the secondary screw linkage lifting mechanism are:

[0004] The lifting speed of a two-stage screw-linked lifting mechanism is limited. Due to the characteristics of the screw drive, the lifting speed is relatively slow, generally only about 15mm / s. This may not meet the needs of some applications that require rapid lifting, directly affecting work efficiency. Especially in applications that require frequent lifting, the speed limitation may become a significant disadvantage. In addition, the high price of the screw directly affects the cost of the entire lifting mechanism.

[0005] Disadvantages of chain hydraulic cylinder linkage lifting mechanism:

[0006] The chain-hydraulic cylinder linkage lifting mechanism contains multiple mechanical components and hydraulic systems. These components have high requirements on the environment. If the hydraulic oil is contaminated or there are impurities inside the system, it may wear out during long-term operation, affecting the positioning accuracy. Regular inspection and maintenance are required, and the maintenance cost is high, including replacing worn parts, cleaning the hydraulic system, and checking the wear of the chain and sprocket.

[0007] In view of the above-mentioned defects, the designer has actively carried out research and innovation in order to create a new type of chain-type two-stage linkage lifting device based on a chassis robot, making it more valuable for industrial use. Utility Model Content

[0008] In order to solve the above technical problems, the purpose of the utility model is to provide a chain-type two-stage linkage lifting device based on a chassis robot.

The outer end of the support transmission shaft is connected to a transmission sprocket two opposite to the transmission sprocket one, and a lifting chain one is connected between the transmission sprocket two and the transmission sprocket one, and a slide rail one is connected to the side of the lifting vertical frame, and the slide rail one is slidably connected to the lifting door frame through a slider, and the lifting door frame is synchronously connected to the transmission sprocket one through a connecting fixed block, and a slide rail two is connected to the side of the lifting door frame, and the slide rail two is connected to the lifting bracket through a slider, and a transmission sprocket three is connected to the outer top of the lifting door frame, and a lifting chain two is meshed with the transmission sprocket three, wherein one end of the lifting chain two is connected to the top of the lifting vertical frame through a connecting fixed plate, and the other end thereof is connected to the lifting bracket.

[0011] Preferably, in the chain-type two-stage linkage lifting device based on the chassis robot, a rubber limiting buffer block is connected to the fixed base plate, and the rubber limiting buffer block is arranged below the lifting mast.

[0012] Preferably, in the chain-type two-stage linkage lifting device based on a chassis robot, limit photoelectric switches are connected to the top and bottom of the lifting frame, and the connecting and fixing block is connected to a sensor sheet that cooperates with the limit photoelectric switch.

[0013] Preferably, in the chain-type two-stage linkage lifting device based on a chassis robot, the motor mounting seat is connected to the fixed base plate by bolts.

[0014] Preferably, in the chain-type two-stage linkage lifting device based on a chassis robot, the transmission chain is a double-chain transmission chain.

[0015] Preferably, in the chain-type two-stage linkage lifting device based on the chassis robot, the lifting chain 1 and the lifting chain 2 are both single-row chains.

[0016] By means of the above solution, the present invention has at least the following advantages:

[0017] This utility model can achieve two-stage linkage lifting. By combining the sprocket chain with the slide rail slider, the lifting speed is fast, with a maximum speed of 0.8m / s. It does not require special environment and has high lifting precision. At the same time, the slide rail slider and sprocket chain of this utility model are relatively low in price, effectively reducing the cost of the mechanism.

It has wide practicality and convenience and is easy to install and debug.
