The invention discloses cargo lifting equipment. The cargo lifting equipment is characterized in that a bottom plate is provided with a ball screw rod, a counterweight block sliding rod, a pulley supporting frame and a lifting bucket sliding groove, a ball screw nut is arranged on the ball screw rod and is connected with the ball screw rod through a ball screw pair, and the lifting position can beaccurately controlled; one end of the ball screw nut is provided with an electromagnetic valve, and the electromagnetic valve is provided with an electromagnetic valve extending shaft; the electromagnetic valve extending shaft can be inserted into holes in counterweight blocks so that the number of the counterweight blocks can be changed conveniently, then the weight of the counterweight blocks can be adjusted conveniently, and the counterweight blocks are installed on the counterweight block sliding rod in a sliding mode; and a pulley is rotationally installed at the upper end of the pulleysupporting frame, the inner side of the lifting bucket sliding groove is connected with a lifting bucket in a sliding mode, one end of the lifting bucket is fixedly connected with one end of a pull rope, and the other end of the pull rope is fixedly connected with the ball screw nut through the pulley. According to the cargo lifting equipment, the design of the pulley and the counterweight blocksare achieved, so that the load of a motor is reduced; and the weight of the counterweight blocks is designed according to the weight of lifted cargos, so that the cargo lifting equipment is suitable for the transportation of various kinds of cargos.
Description
technical field [0001] The invention relates to the field of mechanical equipment, in particular to cargo lifting equipment. Background technique [0002] Cargo lifting equipment is widely used in various transportation occasions, and can transport goods from a low place to a certain high place. During the operation of the cargo lifting equipment, a large driving force is required so as to be able to lift heavier cargo, so the requirements for the driving parts are very high, and the long-term high-load work causes the life of the driving parts to decrease. Therefore, a cargo lifting device is designed. Contents of the invention [0003] The present invention aims to solve the above-mentioned problems existing in the prior art, and provides a cargo lifting device. [0004] The present invention is realized through the following technical solutions: [0005] A cargo lifting device, comprising a ball screw lever, a counterweight, a pulley, an elevator bucket and a bottom ...
