detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1, 2, and 3, a mobile lifting and unloading machine includes a frame 1, a lifting plate 2 and a fork 3, and two parallel linear guide rails 4 are vertically arranged on the frame 1. , a slider 5 is arranged on the linear guide rail 4, the lifting plate 2 is fixedly mounted on the slider 5, the fork 3 is arranged on the lifting plate 2; a fixed pulley 6 is installed on the top of the frame 1, A movable pulley 7 is installed on the lifting plate 2, and the fixed pulley 6 and the movable pulley 7 are connected by a traction rope 8; one end of the traction rope 8 is fixedly connected to the top of the frame 1, and the other end of the traction rope 8 is bypassed in turn The movable pulley 7 and the fixed pulley 6 are wound on the capstan 9, and the capstan 9 is installed on the frame 1.

The fork 3 adopts split structure, and the fork 3 is divided into a left fork and a right fork; There is a guide hole on the top, and the left fork and the right fork are installed on the guide rod 10 through the guide hole of the fork handle; a rotating shaft is arranged in the center of the lifting plate 2, and a symmetrical crank is fixed on the rotating shaft. 11. Both ends of the symmetrical crank 11 are hinged with a connecting rod 16. The connecting rod 16 is divided into a left connecting rod and a right connecting rod. The left connecting rod is hinged with the fork handle of the left fork, and the right connecting rod is connected with the The fork handles are hinged; the symmetrical crank 11, connecting rod 16 and cargo fork 3 form a symmetrical crank-connecting rod-slider mechanism.

The fork head of the pallet fork 3 is configured as a telescopic structure, which can further increase the scope of application of the pallet fork to goods.

A driving handle 12 is connected to the outside of the symmetrical crank 11, and the symmetrical crank 11 can be controlled to rotate through the driving handle 12.

The fixed pulley 6 and the movable pulley 7 form a pulley block, and in order to achieve more labor-saving purpose, the pulley block is at least one set.

A handle 15 is provided on the frame 1 .

Below in conjunction with accompanying drawing, the one-time use process of the present invention is illustrated:

Before use, according to the different loading and unloading goods, in order to meet the personalized loading and unloading, it can be realized by changing the distance between the left fork and the right fork. First, turn the driving handle 12, and then drive the symmetrical crank 11 to rotate, and the connecting rod 16 is moved by the rotation of the symmetrical crank 11, and the left fork and the right fork are driven to slide on the guide rod 10 through the connecting rod 16, thereby realizing In order to adjust the distance between the left fork and the right fork, the fork 3 (left fork or right fork) and the lifting plate 2 are fixed together by tightening and locking the positioning bolts to prevent the fork 3 from loading and unloading. Displacement occurs on the guide rod.

After the selected goods are placed on the pallet fork 3, if the goods need to be raised, only the winch 9 needs to be rotated (hand winch is adopted in this embodiment), and the traction rope 8 is continuously wound by the winch 9 Putting it away will drive the movable pulley 7 to rise, and then drive the lifting plate 2 to lift upwards. The lifting of the lifting plate 2 realizes the lifting of the fork 3, and finally realizes the lifting of the goods.

When using the mobile lifting and unloading machine of the present invention to load and unload cargo, only when the cargo is transported to and removed from the cargo fork 3, it needs to be done manually. The handle 15 can be used to push the mobile lifting and unloading machine of the present invention, which can effectively ensure the loading and unloading efficiency of the goods while reducing the labor intensity of the porters.

The solutions in the embodiments are not intended to limit the scope of patent protection of the present invention, and all equivalent implementations or changes that do not deviate from the present invention are included in the patent scope of this case.
