Embodiment 1
[0016] Embodiment one, figure 1 , figure 2 , image 3 The special-purpose elevator exit shopping cart push device includes three parts: the push device frame, the drive mechanism, and the actuator.
[0017] The frame of the push device is made of steel (3), section steel (9), section steel (13), section steel (17) Composition, the relative positions of the four steel sections are determined by vertically fixing them on the special elevator frame (not shown in the figure), and the frame body of the moving device is the basis for installing the drive mechanism and the actuator.
[0018] The driving mechanism consists of a motor (1), a coupling (2), a driving shaft (4), and a transmission part (5), driving wheel (6), transmission parts (7), driving wheel (8), driven shaft (14), driven wheel (15), passive wheel (16), the executive mechanism is made up of pushrod (10), bearing pin (11), hinge seat (12). It is characterized by: driving wheel (6) and driving ...
Embodiment 2
[0019] Embodiment two, figure 1 , Figure 4 , Figure 5 The executive mechanism in is made up of push rod (10), pin shaft (11), hinge seat (12). It is characterized in that it adopts a single-row actuator, and five hinge seats (12) are evenly distributed around the ring, and these five hinge seats (12) are fixed on the transmission part (5) and transmission parts (7) In the middle, each hinge seat (12) is hingedly installed with a pin shaft (11) to install the push rod (10), and the push rod (10) can rotate clockwise around the pin shaft (11) relative to the hinge seat (12). But it cannot rotate counterclockwise. When it rotates counterclockwise, it is limited by the protrusion structure on the hinge seat (12). The push rod (10) pushes the shopping cart forward through the push armrest of the shopping cart. Without affecting the entry of the shopping cart into the pushing device, the size of the push rod (10), pin shaft (11) and hinge seat (12) of the single-row actuator...

Abstract
A shopping trolley pushing device for a special escalator exit is capable of automatically pushing shopping trolleys and comprises a pushing device frame, a driving mechanism and execution mechanisms. A motor drives the execution mechanisms through a coupler, a driving shaft, driving wheels, transmission parts, driven wheels and a driven shaft, each execution mechanism comprises a hinge seat, a hinge pin and a push rod, the hinge seats, the hinge pins and the push rods are fixedly connected to the transmission parts, and the push rods are capable of rotating around the hinge pins in one direction relative to the hinge seats. In operation, the driving mechanism drives the left and right transmission parts to move forward synchronously in the same direction to automatically push the shopping trolleys, and structural simplicity and reliability in operation are realized.
Description
technical field [0001] The invention relates to a shopping cart pushing device, in particular to a special elevator exit shopping cart pushing device. Background technique [0002] Generally, the elevators for going up and down stairs in large supermarkets use flat elevators. Consumers can push shopping carts up and down the stairs. This kind of flat elevators for going up and down stairs takes up a lot of space, requires a long installation distance, and is limited in use. Most space and distance are limited. In limited shopping malls, a special shopping cart elevator is installed between the two stair elevators. When consumers go up and down the floor to shop, they don't need to push the shopping cart. It moves forward synchronously with the step elevator, which meets the requirements of use, and also has the characteristics of separation of people and vehicles, safety and reliability. The problem that needs to be solved urgently is that in the current shopping cart eleva...
