Description

Technical Field

[0001] The utility model relates to the technical field of warehousing logistics and transportation, in particular to a jacking double-chain roller machine. Background Art

[0002] Lifting roller conveyor is a common material conveying system, mainly used in production lines, warehouses or logistics centers to move, lift or transport goods in an automated or semi-automated manner.

[0003] The jacking roller conveyor combines the traditional roller conveyor with the translational lifting function, increasing operational flexibility. Its operating principle relies primarily on the rolling motion of the rollers and the movement of the lifting mechanism. When cargo is placed on the roller conveyor, the rollers roll under the cargo's own weight or powered by a power source, achieving continuous conveyance. Simultaneously, the lifting mechanism can lift the cargo as needed, completing the lifting and lowering operation.

The cover shell 4 is driven to rise and fall by the jacking mechanism 2, thereby driving the conveying mechanism 1 to rise and fall. At the same time, the jacking member 203 is an eccentric structure, and the jacking member 203 abuts on the cover shell 4. Under the action of the jacking member 203, the height of each jacking is the same, ensuring that the lifting height of the conveying mechanism 1 is consistent and there will be no error. There will be no drop when the object moves to the conveying mechanism 1 or moves out of the conveying mechanism 1, thereby avoiding collision of the object and ensuring that the object will not be damaged during the conveying process.

[0028] Several conveying rollers 101 are arranged in parallel, and conveying sprockets 1011 are provided at the ends of several conveying rollers 101. A synchronous chain 102 is connected between adjacent conveying sprockets 1011. Furthermore, several conveying rollers 101 are distributed along the conveying direction, and gaps are formed between adjacent conveying rollers 101. Several conveying sprockets 1011 are all arranged at the same end of the conveying roller 101, and the several conveying rollers 101 are driven to rotate synchronously by the synchronous chain 102.

[0029] The output end of the driving motor 103 is provided with a driving sprocket 1031, and the driving sprocket 1031 is installed with a transmission chain 104 that drives all the synchronous chains 102 to transmit synchronously. Furthermore, the driving motor 103 is fixed in the cover 4 through a motor seat, and the driving motor 103 drives several conveying rollers 101 to operate through the transmission chain 104.

[0030] A plurality of conveying sprockets 1011 are covered with protective covers 105, which are fixedly arranged on the cover shell 4, and the upper surface of the protective cover 105 is arranged lower than the conveying roller 101.
