Lifting mechanism of schnabel car

Abstract

A lifting mechanism of a schnabel car is mainly characterized in that central disks of the outer ends of two half schnabel car lifting mechanisms are connected with the outer ends of guide beams through ball pairs, the outer end of each guide beam is hinged to the outer end of a front schnabel beam and the outer end of a rear schnabel beam, the upper portions of the inner ends of each front schnabel beam and the corresponding rear schnabel beam which are identical and connected in parallel are hinged to one end of a front outer connecting rod and one end of a rear outer connecting rod, the other end of the front outer connecting rod and the other end of the rear outer connecting rod are hinged to one end of a front inner connecting rod and one end of a rear inner connecting rod, the other end of the front inner connecting rod and the other end of the rear inner connecting rod are connected with the upper portions of goods, and a rotating pair of the front inner connecting rod, a rotating pair of the rear inner connecting rod, a rotating pair of the front outer connecting rod and a rotating pair of the rear outer connecting rod are respectively connected with a piston rod of a lifting oil cylinder, a cylinder body of each lifting oil cylinder is connected with the middle of the inner end of the corresponding schnabel beam, the lower portions of the inner ends of the two corresponding schnabel beams are hinged to one end of a front car lug and one end of a rear car lug, the other end of each front car lug and the other end of the corresponding rear car lug are connected with the lower ends of the goods, and a width regulating mechanism is installed between each front schnabel beam and the corresponding rear schnabel beam. According to the lifting mechanism of the schnabel car, small lifting force is exerted by the lifting oil cylinders so that the goods with the same weight can be lifted, and the lifting mechanism of the schnabel car has the advantage of saving labor.

Description

technical field [0001] The invention relates to a lifting mechanism of a railway transport tong car. Background technique [0002] With the rapid development of my country's national economy, petrochemical, electric power, aerospace, metallurgy and military equipment industries have also developed by leaps and bounds, and there are more and more large cargoes with heavy weight and complex shapes. higher requirements. These large goods are collectively referred to as long goods in railway transportation, and there are three main types of trucks for transporting these long goods, namely large concave bottom cars, clamp cars and drop hole cars, among which clamp cars are the current railway special freight market. One of the main models, it plays a huge role in the transportation of large-scale cargo. It has more functions and has a hydraulic lifting device to make the shipment of cargo more flexible. It is suitable for cargo with self-supporting capacity of different widths, s...

AI Technical Summary

Problems solved by technology

[0003] However, due to the high quality of the goods being transported and the specific structure of the lifting mechanism in the prior art, the output pressure of the lifting cylinder is always maintained at a large value during the lifting of the goods.

At present, there are existing materials, such as Chinese patent CN103101546A, which discloses that by adjusting the synchronization rate of the elongation of the lifting cylinder to improve the stress of the clamping vehicle during the lifting process of the cargo, but this patent does not reduce the output pressure of the lifting cylinder during the lifting process.
