Abstract

The utility model belongs to the technical field of article conveying and transport equipment, and relates to a crawler-type automatic-guided cart. Storage batteries and an automatic control circuit device are fixedly placed at a corner of the top end of a cart body and respectively electrically communicated with controlled components, a driving wheel is fixedly connected with an output shaft of a driving motor prior to being fixed at a top corner inside the box-shaped cart body in an inverted table type square structure, a front traveling wheel and a rear traveling wheel are fixed to two end corners of the inner lower portion of the cart body by shaft type structures, and rims extend for 5cm to 10cm out of the cart body. A tensioning wheel is fixed at the other top corner of the inner top side of the cart body by a shaft structure, the position of an axial point of the tensioning wheel is adjustable, a crawler is rotationally connected with the driving wheel, the front traveling wheel, the rear traveling wheel and the tensioning wheel, and the driving wheel drives the crawler to rotate and lead the two traveling wheels and the tensioning wheel to rotate synchronously. The crawler-type automatic-guided cart is novel in structure, reliable in principle, high in automation degree, work efficiency and controllability and long in service life, saves labor and energy consumption, is safe and stable, and is widely applied to conveying articles in locations such as shopping centers, logistic distribution warehouses and the like.

Description

A kind of crawler type automatical pilot transportation vehicle

Technical field:

The utility model belongs to article and transports and the transmission equipment technical field, relates to a kind of crawler type automatical pilot transportation vehicle, the particularly a kind of unmanned type orientation of occasions such as logistics storehouse and shopping plaza or transportation means of fixed point transporting articles of being applied to.

Background technology:

At present, in some large-scale shopping plaza or supermarket, particularly in some logistics places, often need in indoor environment or outdoor ground grading environment, be transported to another fixing place to some article from a certain place, its transportation track usually is a fixed-direction, existing transportation resources generally includes the people and pushes away, storage battery automobile or forklift, also have and adopt belt transportation, adopt a dead lift in addition, but the operation that all musts be guarded or looked after all the time in these methods, particularly in some straight lines or fixed-direction and place transportation, people's effect is very little, but can have, cause personnel's waste; Particularly existing these haulageman have use fuel oil machinery, energy dissipation is bigger, and article seldom also want a car load to transport sometimes, the time-consuming energy consumption of taking, and easily cause flue gas and dust pollution in the place, particularly the flue gas in some sealing occasions is tended to people's health is worked the mischief; And existing these vehicle structure complexity, use heaviness, degree of automation is low, can not satisfy the traffic requirements of a large amount of article that flow under indoor or ground, the plane occasion.So; at present; people are developing various automatic guided vehicles or instrument in the industry; automatic guided vehicle (Automated Guided Vehicle; abbreviation AGV) is meant homing guidance devices such as being equipped with electromagnetism or optics; can travel along the guide path of regulation, have the transport trolley of safety guard-safeguard and various transfer functions.Not needing the transport trolley of chaufeur in the technical application, is its power resources with chargeable storage battery; Control its course and behavior by computer, or utilize electromagnetic path to set up its course, electromagnetic path is pasted on the what floor, and the message that automatic guided vehicle is then followed electromagnetic path and brought moves and action.

Summary of the invention:

The purpose of this utility model is to overcome the shortcoming that exists in the prior art, seek to design the automatical pilot transportation vehicle of a kind of driverless operation of preparation and the electrodynamic type caterpillar belt structure of direct push-and-pull, the goods of fixed-direction is transmitted in the places, plane such as storehouse that are applied to market and large-scale logistics centre.

To achieve these goals, agent structure of the present utility model comprises storage battery and automatic control circuit device, drive wheel, front walking wheel, rear walking wheel, expansion tightening wheel, car body and crawler belt; One jiao of the independent structure fixed placement of storage battery and automatic control circuit device place on the car body top and respectively with controlled parts electric connection, be fixed on the interior drift angle place of box-like car body of the formula square structure of falling from power behind the output shaft fixed connection of drive wheel and drive motor near battery and automatic control circuit device, front walking wheel and rear walking wheel are separately fixed at place, two ends in bottom angle in the car body by axis structure, and wheel is along stretching out car body 5-10cm; Expansion tightening wheel is fixed on another drift angle place, top side in the car body by axis structure, the axle point adjustable positions of expansion tightening wheel, the endless track rotary type connects drive wheel, front walking wheel, rear walking wheel and expansion tightening wheel and constitutes transmission device, drive wheel drives crawler belt and rotates, thereby front walking wheel, rear walking wheel and expansion tightening wheel are rotated synchronously, crawler belt and ground relative motion are advanced transport trolley or are retreated.

The utility model adopts the both sides crawler travel, and transport trolley advances or retreats during the speed synchronization of both sides; Realize during the both sides speed differences turning to; Can walk on rough road surface, avoid obstacle to stop operation or accident to turn to, crawler belt has skidproof effect simultaneously; Drive wheel is directly load-bearing not, alleviates the load of motor; Its novel structure, principle is reliable, saves manpower and energy consumption, the degree of automation height, high efficiency, controllability is strong, safety and stability, long service life, the occasions such as storehouse that can be widely used in market and logistics distribution centre transmit article.

Description of drawings:

Fig. 1 is a structural principle scheme drawing of the present utility model.

The specific embodiment:

Also be described further in conjunction with the accompanying drawings below by embodiment.

Embodiment;

The agent structure of present embodiment comprises storage battery and automatic control circuit device 10, drive wheel 11, front walking wheel 12, rear walking wheel 13, expansion tightening wheel 14, car body 15 and crawler belt 16; Storage battery and automatic control circuit device 10 fixed placement are on car body 15, drive wheel 11 is connected with drive motor, drive wheel 11 on the drive motor is fixed on car body 15, and front walking wheel 12 and rear walking wheel 13 are fixed on the car body 15 by axle, bears the weight of transport trolley and the weight of load; Expansion tightening wheel 14 is fixing with car body 15 by axle, the axle of expansion tightening wheel 14 can be adjusted the position, endless track 16 rotary types connect drive wheel 11, front walking wheel 12, rear walking wheel 13 and expansion tightening wheel 14, drive wheel 11 drives crawler belt and rotates, thereby make front walking wheel 12, rear walking wheel 13, expansion tightening wheel 14 synchronous interlocks, crawler belt 16 and ground relative motion advance transport trolley or retreat; The motor body of present embodiment is installed in the car body dorsal part, does not indicate the position of the output shaft 17 orientable qualification motor bodies of its motor in the accompanying drawings.
