The two groups of lifting direct-drive servo motors are respectively positioned at one group of diagonal positions at the bottom of the comb rack of the front comb teeth; the two groups of lifting guide sleeves are respectively positioned at the other group of angular positions at the bottom of the comb rack of the front comb teeth.

Two groups of lifting direct-drive servo motors and two groups of telescopic devices direct-drive servo motors are arranged at the bottoms of the rear comb teeth, and the installation mode of the lifting direct-drive servo motors is the same as that of the front chassis.

The technical advantages of the scheme are as follows:

firstly, the intelligent trolley of the scheme adopts servo control, so that the system is stable, the control is flexible, the stopping position is accurate, and the speed is fast;

secondly, the lifting system (lifting direct-drive servo motor) and the telescopic system (telescopic device direct-drive servo motor) both adopt direct-drive servo motors, and the driving walking wheel adopts a planetary reducer (the reducer is arranged in the wheel), so that the size is small, the torque is large, the height of the intelligent trolley is greatly reduced, and the total height of the intelligent trolley adopting the scheme is less than or equal to 160 mm;

thirdly, the front chassis and the rear chassis of the intelligent trolley have only plane processing and do not have boring holes, and the chassis is designed into the front chassis and the rear chassis, so that the processing length of parts is reduced, and the processing precision of the chassis is easily ensured;

fourthly, the intelligent trolley behind the scheme is a direct-drive servo motor except for walking, is not provided with a mechanical device such as a speed reducer, and is a maintenance-free mechanism except that the selected load bearing is an oil bearing with a seal. The planetary reducer that the initiative selection wheel chose for use moves 2 ten thousand hours, and the rack adopts wear-resisting self-lubricating material, and consequently, intelligent vehicle maintenance cost after this scheme is extremely low, and because gear drive is few, its noise is very little.

Detailed Description

The present invention will be further explained with reference to the drawings, and the preferred embodiment of the present invention is: referring to the attached drawings 1 to 3, the full servo direct-drive comb tooth type intelligent trolley comprises a track 1, front comb teeth 2, a telescopic device direct-drive servo motor 3, a front chassis 4, a ball joint connecting rod 5, a rear chassis 6, rear comb teeth 7, guide wheels 8, passive traveling wheels 9, a lifting direct-drive servo motor 10, a lifting guide sleeve 11 and active traveling wheels 12, wherein the front chassis 4 and the rear chassis 6 are both arranged on the track 1, the front chassis 4 and the rear chassis 6 are movably hinged through the ball joint connecting rod 5, the bottom of the front end of the front chassis 4 is provided with the guide wheels 8, the wheel surfaces of the guide wheels 8 are in contact with the inner side wall of the track, the middle of the front chassis 4 is fixedly provided with the lifting guide sleeve 11 and the lifting direct-drive servo motor 10, the top of the lifting direct-drive servo motor 10 and the lifting guide sleeve 11 is provided with the front comb teeth 2, the front comb teeth 2 are driven by a gear and a, the two sides of the rear chassis 6 at one end of the front chassis 4 are provided with active walking wheels 12, and the middle part of the rear chassis 6 is provided with rear comb teeth 7. Driven traveling wheels 9 are mounted on two sides of the front chassis 4 between the lifting direct-drive servo motor 10 and the guide wheels 8, tail traveling wheels are mounted at the tail of the rear chassis 6, and the driven traveling wheels 9, the driving traveling wheels 12 and the tail traveling wheels all travel on the track 1. Two groups of lifting direct-drive servo motors 10 are respectively positioned at one group of diagonal positions at the bottom of the comb rack of the front comb teeth 2; the two groups of lifting guide sleeves 11 are respectively positioned at the other group of angular positions at the bottom of the comb rack of the front comb teeth 2. Two groups of lifting direct-drive servo motors 10 and two groups of telescopic devices direct-drive servo motors 3 are arranged at the bottom of the rear comb teeth 7, and the installation mode of the lifting direct-drive servo motors is the same as that of the front chassis 4. The lifting direct-drive servo motor 10 pushes the comb teeth to move up and down, the lifting guide sleeve 11 can ensure the stable up-and-down movement of the comb teeth to guide the up-and-down movement of the comb teeth,

the intelligent trolley is a device walking on the square track 1. The chassis of the trolley is formed by connecting a front chassis 4 and a rear chassis 6 through a spherical hinge connecting rod.
