Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions with reference to the accompanying drawings of the present invention.

The utility model discloses what demonstrate is a district commodity circulation that can take turns to track switches and shiies platform, as shown in figure 1, 2, 3, 7, is comparatively optimized implementation scheme, the utility model discloses can be according to the district level land, the difference of step or stair, automatic switch-over motion mode. Fig. 8 is the mechanism schematic diagram of the wheel-track switching device of the present invention, the gear 29 is sleeved in the middle of the switching hydraulic push rod 17, and the gear 29 and the switching hydraulic push rod 17 are axially fixed. The rack plate 30 has slender baffles on its two sides to limit the gear 29 to move left and right, and is fixed to the chassis 18 and meshed with the gear 29, the front connecting shaft 27 and the back connecting shaft 28 are hinged to the hydraulic switching push rod 17, and the front shaft 31 and the back fulcrum 32 are fixed to the chassis 18 via bearing seats 26. When the hydraulic push rod extends and contracts, the front connecting shaft 27 and the rear connecting shaft 28 drive the switching hydraulic push rod 17 to move up and down, and the gear 29 also moves up and down according to the interaction principle. The motor is mounted on the motor mount bracket 34.

When the utility model discloses move to step or stair before, sensor 22 can send road surface situation to controlling means, and controlling means controls the work of small-size hydraulic pressure workstation 14, switches hydraulic push rod 17 and controls both ends extension. At the moment, the front connecting shaft 27 and the rear connecting shaft 28 respectively swing around the front shaft 31 and the rear shaft 32 under the action of the switching hydraulic push rod 17, so that the front rocker 11 and the rear rocker 12 are driven to swing around the front shaft 31 and the rear shaft 32, the universal wheel 13 and the hub motor wheel 15 are lifted, the chassis 18 descends, the crawler belt 2 is in contact with the ground, the crawler belt motor 16 works to drive the crawler belt front wheel 3 to rotate, the crawler belt 2 moves under the driving of the crawler belt front wheel 3, the driven wheel 4 and the guide wheel 5, and the trolley is switched to track type movement. When the first-layer steps of the trolley are arranged below, in order to prevent the trolley from being turned forwards possibly caused by the fact that the front half part of the caterpillar type movement of the trolley is not in contact with the step surfaces and is stepped, the front auxiliary hydraulic push rod 23 can extend to enable the front auxiliary support frame to rotate to be in contact with the step surfaces, the rear auxiliary hydraulic push rod 25 pushes the rear auxiliary support frame to rotate to be in contact with the ground, the front auxiliary hydraulic push rod and the rear auxiliary hydraulic push rod are matched, the caterpillar surface and the step inclined surfaces are level, and the purpose of. In addition, because the universal wheels 13 and the hub motor wheels 15 are arranged on the outer sides of the front crawler wheels 3, the wheel axial distance is variable, and the side turning of the vehicle body can be effectively prevented. Similarly, when the express delivery vehicle moves to a flat road surface of a community, the sensor 22 sends the road surface condition to the control device, the control device controls the small hydraulic workstation 15 to work, the hydraulic push rod is switched to contract, the front rocker 11 and the rear rocker 12 swing around the front support shaft 31 and the rear support shaft 32 in opposite directions, the universal wheel 13 and the hub motor wheel 15 descend, the vehicle body framework 18 ascends, and the express delivery vehicle is switched to wheel type movement. Because the hydraulic push rod works stably and the moment is large, the carrying platform can stably switch the motion mode according to the road surface condition, and the application range and the efficiency of the carrying platform are greatly improved.

The utility model discloses carrier and the fixed mode together of platform have carried out the effectual improvement of science to present market, adopt slide 35, locating plate 20, carriage padlock 8, and platform knot body 9 realizes that platform and carrier part, the effect of free loading and unloading. As shown in fig. 1 and 3, the box body with the bottom having the groove matching with the slide way can smoothly slide into the slide way 35 of the platform from the transition plate 21, the box body can only move back and forth after entering the slide way 35, but cannot swing left and right, the front part of the box body slides to match with the positioning plate 20 and then is further fixed on the platform, and finally, 4 carriage latches 8 on the carriage can be rotated to make the latch bars buckle on 4 platform buckles 9, thereby realizing the tight connection between the box body and the platform. Similarly, when the box body needs to be replaced or unloaded, a person rotates the 4 box body locks 8 on the box body to separate the buckling strips from the 4 platform buckling bodies 9, and the box body is moved to be easily disassembled.

The utility model discloses improve the intellectuality and the practicality design of commodity circulation platform, this express delivery car can carry out the switching of motion mode according to the difference of district road conditions, and wheeled motion is adopted on the level land, and step or stair adopt the crawler type motion, and intelligence is stable, effectively promotes the application promotion of intelligent express delivery car, and carrier and platform separation make this commodity circulation platform can carry on multiple carrier, have greatly improved district commodity circulation platform's range of application and work efficiency, have stronger flexibility and adaptability.

The above, only do the utility model discloses a preferred embodiment, it is not right the utility model discloses do any restriction, all according to the utility model discloses the technical entity all belongs to any simple modification, change and equivalent structure transform that the above embodiment was done the utility model discloses technical scheme's within range of protection.
