Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 2, the angle-adjustable rotary fork according to the technical scheme of the invention comprises a fork body, wherein the fork body comprises a first fork and a second fork telescopically connected with the first fork, the first fork and the second fork respectively comprise a bottom plate 2 and a side plate 1 connected with one end of the bottom plate 2, the bottom plate 2 comprises an upper bottom plate 21 and a lower bottom plate 22, the upper bottom plate 21 is rotatably connected with the side plate 1, the lower bottom plate 22 is fixedly connected with the side plate 1, a jacking mechanism 3 is arranged between the upper bottom plate 21 and the lower bottom plate 22, and the lower bottom plate 22 rotates a certain angle around a rotary connection part with the side plate 1 under the jacking action of the jacking mechanism 3.

Based on the technical scheme, the lower bottom plate 22 is fixedly connected with the side plate 1, the firmness of the fork body and the bearing capacity of the fork are guaranteed, the upper bottom plate 21 is connected with the side plate 1 through the rotating shaft 14, the upper bottom plate 21 rotates by a certain angle around the rotating connection position with the side plate 1 under the driving of the jacking mechanism 3 (it is worth explaining that the rotating angle of the upper bottom plate 21 is within 0-15 degrees), so that the upper bottom plate 21 inclines by a certain angle relative to the lower bottom plate 22, the goods are subjected to the acting force of the lower bottom plate 21 and the side plate 1 at the same time, and the stability of the goods is improved. Simultaneously, through the bilayer structure of upper bottom plate 21 and lower floor's bottom plate 22, lower floor's bottom plate 22 climbing mechanism 3 has the supporting role, only needs to rotate upper bottom plate 21 just can realize the firm of goods, need not the whole emergence of fork and rotates, and this has just reduced the shake of fork to and reduce the displacement of goods, further realize the safe and steady transportation of goods.

As shown in fig. 1 and 2, a universal wheel 4 is arranged at an end portion, close to the lower bottom plate, of one side of the lower bottom plate 22 far from the side plate 1, a containing cavity 7 is arranged on a body of the lower bottom plate 22, far from the side plate 1, of the lower bottom plate 22, and the jacking mechanism 3 is arranged in the containing cavity. The universal wheel 4 comprises a fixed block 41 fixed with the lower bottom plate 21, a rotating plate 42 rotatably connected with the fixed block and a rolling shaft 43, and when the forklift transports goods, the universal wheel 4 is in contact with the ground, and the shaking of the pallet fork is reduced due to the supporting effect of the universal wheel 4. The jacking mechanism 3 is arranged in the cavity of the lower bottom plate 322, so that the space is saved, and the upper bottom plate 21 can support goods more stably under the support of the lower bottom plate 22.

As shown in fig. 1 and 2, the jacking mechanism 3 includes a cylinder 31, the cylinder 31 is disposed in an inclined manner, a cylinder push rod 32 of the cylinder 31 is fixedly connected to the bottom surface of the upper bottom plate 21, and a plurality of arc-shaped protrusions 5 are disposed on the surface of the upper bottom plate 21. The inclined arrangement of the cylinder 31 ensures smooth rotation of the upper floor 21. The protruding 5 of arc on upper floor 21 surface increases the friction way of upper floor 21 and goods bottom, prevents the goods landing. The bottom surface of the lower bottom plate 22 is provided with a wire groove 8 for supplying power to the air cylinder 31.

As shown in fig. 1, 2 and 4, the side of the side plate 1 far from the bottom plate 2 is provided with a hanging plate 6, and the side surface of the side plate 1 is provided with a first hook 9 and a second hook 10, the first hook 9 and the second hook 10 are vertically arranged, the hanging plate 6 is provided with a hanging groove 61 corresponding to the positions of the first hook 9 and the second hook 10, the hanging groove 61 is provided with a plurality of hanging grooves along the horizontal direction, the hanging plate 6 is connected with a slide block 11, and the slide block 11 is arranged in a slide groove 12 of the forklift. The hanging grooves 61 are provided with a plurality of reinforcing plates 62 along the horizontal direction, and a plurality of reinforcing plates 62 are arranged among the hanging grooves 61. The hanging groove 61 can adapt to forks with different widths, and the first hook 9 and the second hook 10 which are arranged up and down ensure the firmness of hanging.

As shown in fig. 3, an expansion link 13 is connected between the upper bottom plate of the first fork and the upper bottom plate of the second fork, the expansion link 13 is horizontally arranged at a position close to the side plate of the upper bottom plate, and the rod body of the expansion link 13 is perpendicular to the lower bottom plate. The telescopic rod 13 stretches and retracts to change the distance between the first fork and the second fork, so that the fork lifting device is suitable for the requirements of different goods on the width of the forks, and because the hanging plate 6 is provided with the hanging grooves, when the telescopic rod 13 capable of ensuring changes the distance between the first fork and the second fork, the hanging points can be found by the first hook 9 and the second hook 10.

The working principle of the invention is as follows: after the fork has forked the goods, round rotating certain angle in the curb plate junction through the upper floor, guarantee that the goods receives the resultant force effect of bottom plate and curb plate, when the upper floor rotates, because the connection of telescopic link, the upper floor of guaranteeing first fork is the same with the upper floor turned angle of second fork, the telescopic link has the distance between the second fork through flexible first fork of coming regulation simultaneously, the goods is transporting the in-process, the universal wheel contacts with ground all the time, reduce the shake of fork, when placing the goods, it can to descend to the horizontality with the upper floor.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
