Technical Field

The invention belongs to the technical field of transportation equipment, and particularly relates to a mechanical self-leveling carrying trolley for express delivery.

Background

In recent years, the express industry is rapidly developed, and the express business volume is continuously increased, so that great challenges are brought to the express industry. Because still adopt artifical transportation at the in-process of most express delivery transportation, the express delivery transport vechicle has become the necessary transport means of express delivery trade, and is visible everywhere at each express delivery post house.

The existing carrying trolley is generally composed of a carrying plate, a supporting frame and a carrying trolley, and only can be used for placing articles, so that the carrying trolley is single in performance. When the ground is uneven or goes up and down a slope, the carrying trolley often inclines, so that the goods fall and are even damaged, the logistics efficiency is reduced, and safety accidents are easily caused. And when the goods were loaded in the letter sorting, rely on artifical transport usually, when the goods was heavier, artifical transport was wasted time and energy, has increased staff's intensity of labour, has reduced letter sorting efficiency. The common carrying trolley for express delivery can not meet the increasingly developed use requirements, but the carrying trolley capable of realizing automatic cargo leveling does not exist in the prior art.

Disclosure of Invention

The invention aims to solve the technical problem of providing a mechanical self-leveling delivery trolley for express delivery, which is suitable for occasions where the ground of the delivery trolley is uneven or the delivery trolley needs to go up and down a slope for transportation, realizes mechanical automatic leveling of the delivery trolley by utilizing the gravity pointing effect of a heavy hammer, and is simple and efficient.

1. In order to solve the technical problems, the technical scheme of the invention is as follows: the utility model provides a mechanical type is from levelling carrying trolley for express delivery, its innovation point lies in: the heavy hammer carrying device comprises a support frame, a support plate, a carrying plate and a heavy hammer, wherein the support frame is fixedly connected with a carrying vehicle through a support baffle; the supporting frame is provided with a supporting plate which is connected with the supporting frame and has a convex cross section, four corners of the supporting plate are provided with through holes matched with the supporting frame, and the lower end part of the through hole of the supporting plate is fixedly connected with an adjusting nut; the support frame penetrates through the through hole of the support plate and is in threaded connection with the adjusting nut, the adjusting nut can move up and down along the support frame to push the support plate to move up and down, and the adjusting nut is fixed by a set screw;

l-shaped extending bosses extending from outside to inside are symmetrically arranged on two sides of the upper end of the supporting plate, an upper conical hole and a lower conical hole which are communicated with each other are arranged at the upper end and the lower end of the middle part of the supporting plate, and conical rubber pads matched with the upper conical hole are arranged in the upper conical hole; the weight is arranged in the middle of the supporting plate, a rod body of the weight sequentially penetrates through the lower conical hole, the conical rubber pad and the upper conical hole, the diameter of the rod body of the weight is larger than the inner diameter of the conical rubber pad, and the end part of the rod body of the weight is welded with the object carrying plate;

the carrying plate is arranged between the upper end part of the supporting plate and the upper end part of the L-shaped extending boss, the lower end of the carrying plate is provided with a pressure-bearing foam plate, and a plurality of sensors are uniformly glued between the carrying plate and the pressure-bearing foam plate; carry thing board upper end and be equipped with square rail, place the slipmat in the square rail of thing board, place the goods on the slipmat, carry the thing board outside and be equipped with the shirt rim, the side is equipped with upside buffer spring and downside buffer spring respectively about the shirt rim, goes up upside buffer spring sets up and stretches out the boss and carry between the thing board upper end at the L type of backup pad, and downside buffer spring sets up in the backup pad and carries between the thing board lower extreme.

Further, the upper side buffer spring comprises an upper side buffer inner spring and an upper side buffer outer spring, and the lower side buffer spring comprises a lower side buffer inner spring and a lower side buffer outer spring.

Further, the stiffness of the upper side buffer inner spring is smaller than that of the upper side buffer outer spring, and the length of the upper side buffer inner spring is larger than that of the upper side buffer outer spring.

Further, the stiffness of the lower side buffering inner spring is smaller than that of the lower side buffering outer spring, and the length of the lower side buffering inner spring is larger than that of the lower side buffering outer spring.

Further, the rigidity of the upper side buffer spring is smaller than that of the lower side buffer spring.

Further, the taper angle of the upper conical hole and the lower conical hole is 60 degrees, so that the leveling angle of the cargo is 0-60 degrees.

Further, the sensors are arranged on the lower side of the loading plate at intervals of 30-60 degrees, and the sensors are pressure strain gauges.

The invention has the advantages that:

(1) the carrying trolley for the mechanical self-leveling express delivery realizes the mechanical automatic leveling of the goods by reasonably selecting the weight and the placing position by utilizing the gravity pointing action of the heavy hammer, measures the weight and the deviation degree of the goods by the sensor, solves the problem of unstable goods caused by the random placement of the goods on the carrying trolley, and is simultaneously suitable for the carrying trolley to be placed on the ground to incline or to go up and down the slope in the transportation process, thereby improving the safety of goods storage;

(2) the invention relates to a mechanical self-leveling carrying trolley for express delivery, wherein an upper buffer spring and a lower buffer spring are combined by an inner buffer spring and an outer buffer spring, and the applicability of the carrying trolley is improved by arranging an inner spring with small rigidity and large length and an outer spring with large rigidity and small length; when the ground inclination angle or the cargo mass is smaller, the inner spring with small rigidity and large length only plays a role, and when the ground inclination angle or the cargo mass is larger, the inner spring with small rigidity and large length and the outer spring with large rigidity and small length play a role together, so that the application range of the carrying trolley is improved, and the impact in the transportation process of the carrying trolley is further reduced.
