Problems solved by technology
For the lifting mechanism of multiple hydraulic cylinders, the main problem to be solved is the synchronous lifting of multiple hydraulic cylinders. If the lifting speed and position of each hydraulic cylinder cannot be synchronized during the lifting process of heavy objects, corresponding to heavy objects, hydraulic pressure The position of each support point formed by the oil cylinder deviates, which is easy to cause the rollover of the heavy object

The invention discloses a multi-cylinder synchronous lifting mechanism. The multi-cylinder synchronous lifting mechanism comprises a left lifting cylinder, a right lifting cylinder, a loader, a flange, a pin seat, a pin shaft, a pressing rod, an oil tank, a first throttle valve, a second throttle valve, a third throttle valve, a fourth throttle valve, a first one-way valve, a second one-way valve, a third one-way valve, a fourth one-way valve and a plurality of pipelines. As for heavy goods in small size, the goods can be lifted by a single hydraulic cylinder, and if the size of the heavy goods is large, the goods can be lifted through a plurality of hydraulic cylinders. As for the lifting mechanism with the plurality of hydraulic cylinders, synchronous lifting of the plurality of hydraulic cylinders is required, if lifting speeds and positions of the hydraulic cylinders are not synchronous and can not correspond to the heavy goods in the process of lifting the heavy goods, deviation of each supporting point position of the hydraulic cylinders is caused, and the heavy goods tend to roll over. The multi-cylinder synchronous lifting mechanism is simple in structure, reliable in operation, and multi-cylinder synchronous stable lifting and descending of the heavy goods in large size can be fully guaranteed.
Description
Technical field [0001] The invention relates to a multi-cylinder synchronous lifting mechanism, in particular to a weight synchronous lifting mechanism realized by a plurality of hydraulic oil cylinders, and belongs to the electrical and electromechanical technical field. Background technique [0002] At present, hydraulic cylinders have been widely used in many occasions to achieve the lifting of heavy objects. For small-sized heavy objects, a single hydraulic cylinder can be used to achieve the lifting. If the size of the weight is relatively large, only a single hydraulic cylinder can be used to achieve the lifting. It is easy to cause heavy objects to roll over, so multiple hydraulic cylinders are usually used to lift large-size heavy objects. For the lifting mechanism of multiple hydraulic cylinders, the main problem that needs to be solved is the synchronous lifting of multiple hydraulic cylinders. If the lifting speed and position of each hydraulic cylinder cannot be synch...
