Detailed Description

As shown in fig. 1 to 4, a forklift includes a frame, rollers provided at a lower end of the frame, an electric cylinder and a battery for supplying power to the electric cylinder provided on the frame, a four-bar mechanism provided above the frame, a lower end of the four-bar mechanism supported on a push rod of the electric cylinder, a fork provided at a front end of the four-bar mechanism, and a handle provided at a rear end of the frame. The roller is arranged below the rack, so that a user can push the equipment conveniently; when the electric cylinder can push the four-bar mechanism to move up and down, the four-bar mechanism can drive the fork frame to move up and down by moving up and down, the fork frame is arranged at the front end of the four-bar mechanism, and the fork frame can perform larger displacement in the vertical direction through the four-bar mechanism; the storage battery provides power for the electric cylinder.

In this embodiment, the four-bar mechanism includes a first bar body, a second bar body, a third bar body and a fourth bar body which are sequentially hinged end to end, the first bar body is hinged to a push rod of the electric cylinder, the second bar body is fixed on the frame, a first hinge shaft is disposed between the first bar body and the second bar body, a second hinge shaft is disposed between the second bar body and the third bar body, a third hinge shaft is disposed between the third bar body and the fourth bar body, a fourth hinge shaft is disposed between the fourth bar body and the first bar body, the determined plane of the first hinge shaft and the second hinge shaft is a vertical plane, the distance between the first hinge shaft and the second hinge shaft is set to be L1, the distance between the third hinge shaft and the fourth hinge shaft is set to be L2, the distance between the first hinge shaft and the fourth hinge shaft is set to be L3, the distance between the second hinge shaft and the third hinge shaft is set to be L4, then L1= L2, L3= L4. As can be seen from fig. 2, four hinge points of the four-bar mechanism are connected end to obtain a quadrangle, the side distances of the quadrangle are L1, L2, L3 and L4, and L1= L2, and L3= L4, so that the quadrangle is a parallelogram, when the electric cylinder extends or contracts, the four-bar mechanism is driven to move, in the moving process of the four-bar mechanism, because the second rod body is fixed on the frame, and the plane defined by the first hinge shaft and the second hinge shaft is a vertical plane, when the four-bar mechanism moves, the plane defined by the third hinge shaft and the fourth hinge shaft is always a vertical plane, so that the horizontal part of the fork frame is kept horizontal, and when an object is prevented from being transported, the object slides from the fork frame all the time.

In this embodiment, the yoke is fixed to the front end of the fourth bar.

In this embodiment, an extension button for controlling the extension of the electric cylinder and a retraction button for controlling the retraction of the electric cylinder are provided on the armrest.

The specific implementation mode is as follows: when the electric forklift works, the contraction button is pressed manually to enable the push rod of the electric cylinder to contract to the lowest, the electric cylinder drives the four-bar mechanism to descend when contracting, the fork frame is driven to descend to the lowest, the forklift is pushed forwards through the handrail, the extension button is pressed manually to enable the push rod of the electric cylinder to extend out by a proper length, the push rod of the electric cylinder extends out to drive the four-bar mechanism to ascend, the fork frame is driven to support an article to ascend to a proper height, and the forklift is driven to move through the handrail to fork the article.

Above-mentioned operation flow and software and hardware configuration only do as the preferred embodiment of the utility model discloses a not therefore restrict the patent scope of the utility model, all utilize the utility model discloses the equivalent transform of doing of description and attached drawing content, or directly or indirectly use in relevant technical field, all the same reason is included in the patent protection scope of the utility model.
