DETAILED DESCRIPTION

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on FIG. 1 and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

As shown in Fig. 1-2, an assembly line trolley transfer device includes a base 1, wheels 2, a stand 3, a support plate 4, a lifting frame 5, a jack 7, and a pallet 9. The base 1 is U-shaped, and wheels 2 are arranged at the four corners of the bottom of the base 1. Stands 3 are fixedly connected to the two side walls of the base 1, and a support plate 4 is fixedly connected to the middle of each stand 3. A jack 7 for driving the lifting frame 5 to rise and fall is arranged on each support plate 4. The bottom of the lifting frame 5 is connected to a pallet 9 for transporting a trolley through an adjusting mechanism.

Specifically, the base 1 is U-shaped, and the trolley can pass through the gap of the base 1 so that the trolley is located between the two lifting frames 5; a support plate 4 is fixedly connected to the middle of each vertical frame 3 for supporting the jack 7; when the lifting frame 5 is driven to rise and fall by the jack 7, the support plate 9 is simultaneously driven to rise and fall, thereby lifting the trolley.

Preferably, a slide rod 8 is fixedly connected to the vertical frame 3 , and the axial direction of the slide rod 8 is perpendicular to the horizontal plane. A slider 11 is fixed to the lifting frame 5 , and the slider 11 is slidably matched with the slide rod 8 .

Specifically, each lifting frame 5 is connected to two slide bars 8 via a slider 11; when the lifting frame 5 is raised or lowered, the slider 11 is raised or lowered synchronously, and then the slider 11 slides on the slide bar 8 to have a guiding function, thereby ensuring the stability of the lifting frame 5 when being raised or lowered.

Preferably, a connecting plate 6 is connected between the two stands 3 .

Specifically, the connecting plate 6 connects the two stands 3 to increase the stability of the stand 3 structure.

Preferably, the adjustment mechanism includes screw rods 12 and nuts 13 , and a plurality of screw rods 12 are fixedly connected to the side of the support plate 9 , the screw rods 12 pass through the lifting frame 5 , and nuts 13 for fastening the screw rods 12 to the lifting frame 5 are threadedly connected.

Specifically, the nut 13 is screwed to loosen the clamping lifting frame 5 , and then the position of the support plate 9 is adjusted to adapt to trolleys of different sizes, and then the nut 13 is screwed to clamp the lifting frame 5 to tighten the screw rod 12 .

Preferably, a handle 10 is further included, and the handle 10 is connected to the two jacks 7 to facilitate the operation of the jacks 7.

Specifically, the operator pulls the handle 10 to make it swing up and down, and then drives the piston of the jack 7 to move, so that the jack 7 drives the lifting frame 5 to move up and down.

In the above structure, the device is pushed to move to the position of the trolley, and the trolley is placed between the two support plates 9, and then the handle 10 is pushed to shake to drive the jack 7 to operate, so that the jack 7 extends to drive the lifting frame 5 to rise, and then drive the support plate 9 to rise, so that the support plate 9 lifts the trolley, and after lifting it can be transported, the jack 7 is retracted and the lifting frame 5 is lowered, and then the trolley is unloaded.
