Background technique

Hoisting machinery is an important auxiliary machinery in heavy lifting, transportation and other operations, which can reduce the physical labor of workers and improve work efficiency. At present, in construction sites and factory buildings, large-scale cargo transportation and hoisting are completed by large gantry and bridge cranes. However, gantry and bridge cranes are mostly limited by space and can only play a role in specific situations. For small and medium-sized goods in factory warehouses, wharf loading and unloading and railway road maintenance, forklifts or manual handling are often used, which increases the output of manual labor, and the efficiency is very low. This requires the design of a lifting device that can carry multiple heavy objects at the same time, and can lift and place them at the same time, save the working time of lifting heavy objects, improve work efficiency, and accurately complete the placement task. .

Detailed ways

The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

The crane adopts the Mecanum wheel 104 as the wheel mechanism, which can realize the straight forward and backward movements of the whole machine, endows the crane with strong flexibility, and greatly adapts to different working environments. Through the working characteristics of the Mecanum wheel 104, it realizes Adaptability to various road conditions. The chassis device 1 concentrates most of the weight of the whole machine, so that the whole center of gravity of the whole machine is moved down, and the stability is improved.

All clamps in the lifting device are driven by the clamping cylinder 304, which ensures the power of the clamping arm 301, and can improve the safety of the entire lifting process and avoid the occurrence of safety accidents.

During the working process, the crane is firstly moved to the cargo clamping area by human manipulation. As shown in the attached figure, the clamping part of the crane is equipped with multiple clamping arms 301. When working, the operator controls the crane to move to the front of the lifting cargo, etc. proper location. The clamp arm 301 is initially located at the bottom of the crane chassis device 1, and the operator directly controls any clamp arm 301 to open. After the operation is completed, the crane is controlled to move forward, and when all the goods are within the clamping range, the clamping operation is performed in time. The cylinder 304 controls the closing of the clamp arm 301 to realize the clamping of the goods. The operations among the three grippers are independent of each other and do not affect each other, which greatly improves the freedom and selectivity of the cargo clamping. Next, the lifting cylinder 203 is controlled by the operator to lift part of the crane clamp, realizes the lifting of the goods, continues to control the crane to move forward, waits until the crane clamp part is completely moved to the next lifting area, and the operating clamp arm 301 is opened (by the clamping cylinder) 304 control), load the cargo on the top of the next cargo, move the clamp arm 301 to the bottom of the crane chassis device 1, repeat the initial lifting steps, and realize the secondary lifting of the cargo, and the stiffness correction link is supplemented during the lifting process. The simple wire rope is used to extract the clamp arm to offset a part of the gravity of the cargo, and at the same time, the support pad 303 at the bottom of the clamp arm can provide a certain supporting force. The entire handling process omits the complicated positioning process, thereby improving the lifting efficiency.

The drive motor 103, lifting cylinder 203, and clamping cylinder 304 used in the chassis device 1, lifting device 2, and clamping device 3 of the lifting equipment are all directly controlled by the program module, making the entire handling work more accurate and reliable, avoiding Interference of human factors, no manual cab for lifting equipment, simplifies the overall structure. Make lifting equipment work more quickly and accurately.
