Abstract
A four-degree-of-freedom multilayer parallel lifting mechanism for a clamp car mainly comprises bases A, adjustment oil cylinders, hinges A, supporting beams, spherical hinges A, bases B, forcipated beams, hinges B, spherical hinges B, lifting oil cylinders, spherical hinges C and a tray. The inner sides, at the two sides of goods, of the four-degree-of-freedom multilayer parallel lifting mechanism are opposite with the center line of the goods as the symmetry axis. According to the four-degree-of-freedom multilayer parallel lifting mechanism for the clamp car, the load capacity of the lifting mechanism is effectively improved, and the lifting mechanism can be used for lifting and transporting super-heavy goods; the work space of the lifting mechanism is effectively increased, the influence of unbalanced loading of the goods on the lifting mechanism is reduced, and the lifting mechanism can be used for transporting super-wide goods; due to the fact that a multi-drive coordinative working mode is adopted, the lifting mechanism can be used for loading and unloading goods more conveniently and more flexibly.
Description
Technical field
The present invention relates to a kind of four-degree-of-freedom Multi-layer Parallel Planar Mechanisms lift system.
Background technology
Along with the enforcement of the upgrading of China Promoting Industrial and energy-saving and emission-reduction Strategic Measure, future will develop extra-high voltage transformer, the superpower electrical complete set of equipment such as high-rating generator, and the weight of these large-scale energy devices will reach nearly kiloton.For guaranteeing that these special goodss start shipment safety, also requirements at the higher level are proposed to the safe reliability of its transport schnabel car.Along with the development of above-mentioned transportation of special goods demand, domestic and international schnabel car technology is towards maximization, superelevation load-carrying, high safety reliability development.Therefore, the active demand that development can bear super-heavy load, high safety reliability schnabel car has become China Railway field.The schnabel car load carrying ability of the existing structure of current employing promotes very limited.Therefore, from schnabel car body design, building the new configuration of schnabel car that can bear super-heavy load, is the key improving schnabel car load carrying ability.Less about the patent of schnabel car both at home and abroad, the patent wherein relating to lift system is less, such as technology disclosed in Chinese patent CN101475007A, it is by changing schnabel car self-supporting structures, reduce body gravity and complete vehicle quality to the convenience of the load carrying ability and transport that improve car load, but due to the restriction of configuration, this technology is not also suitable for super-heavy load, the starting shipment of ultra-wide goods; Technology disclosed in Chinese patent CN103101546A, it improves the stressing conditions of schnabel car in freight lifting process by the sync rates coordinating the work of schnabel car elevating ram, but the elevating ram operation pressure do not reduced in lifting process, is not suitable for the transport of super-heavy load goods equally; Technology disclosed in Chinese patent CN104192155A, it effectively reduces the load of the elevating ram in lifting process by the drive arrangements changing lift system, but also there is certain application limitation for super-heavy load, starting shipment of ultra-wide goods.
Summary of the invention
The object of the present invention is to provide one to be applicable to the large-scale equipment of transfiniting such as super-heavy load, ultra-wide to hoist transport, and loading and unloading operation schnabel car four-degree-of-freedom Multi-layer Parallel lift system more flexibly.
Schnabel car four-degree-of-freedom Multi-layer Parallel lift system mainly includes: pedestal A, adjustment oil cylinder, hinge A, support beam, ball pivot A, pedestal B, schnabel, hinge B, ball pivot B, elevating ram, ball pivot C and pallet.Wherein, three pedestal A are placed on horizontal surface, and the top of each pedestal A regulates the fixed end of oil cylinder hinged with one respectively, regulate the piston rod of oil cylinder hinged by one end of hinge A and support beam.Lower end in the middle part of every root support beam is connected with the upper end of pedestal B by ball pivot A.Lower end in the middle part of the other end of every root support beam and schnabel is hinged by hinge B.One end of schnabel and the upper articulation of ball pivot B, the bottom of ball pivot B is connected with the piston rod of elevating ram, and the upper end in the middle part of the fixed end of elevating ram and support beam is hinged by ball pivot C.The other end of schnabel is hinged with a side of pallet respectively, and pallet is level side's plate.Above-mentioned parts composition schnabel car four-degree-of-freedom Multi-layer Parallel lift system.With the line of centers of goods for axis of symmetry, inside the schnabel car four-degree-of-freedom Multi-layer Parallel lift system of goods both sides in opposite directions.
Freight lifting process of the present invention: stop two and half cars opposite to each other in orbit, pallet is positioned over two halves car midway location, by hinged with pallet two ends inside two halves car clamp beam, regulate two halves car to correct position, as shown in Figure 3, drive and regulate cylinder efficient, support beam and pallet are adjusted to appropriate location, one and half cars are kept to be in braking mode, another half car is in servo-actuated state, goods is hung in the middle of two and half cars, pulsation-free is placed on pallet, ensure symmetrical placement as far as possible, place complete, start and regulate oil cylinder and elevating ram work, by oil cylinder co-ordination, goods is adjusted to correct position and clamps goods, ensure that the safety of goods transport.
The present invention compared with prior art tool has the following advantages:
1, the present invention adopts Multi-layer Parallel Planar Mechanisms lift system, effectively increases the load carrying ability of lift system, can be applicable to lifting and the transport of super-heavy load goods;
2, the present invention adopts Multi-layer Parallel Planar Mechanisms lift system, effectively increases lift system working space, reduces goods unbalance loading to the impact of lift system simultaneously, can be applicable to the transport of ultra-wide goods;
3, the four-degree-of-freedom of schnabel car described in the present invention Multi-layer Parallel lift system, adopts many driving co-ordination patterns, makes its handling goods flexibly convenient.
