Description
Technical Field
The utility model belongs to railway vehicle's bulk cargo handling equipment, in particular to parallel four-bar linkage pressure car device with activity counter weight.
Background
The car dumper pressing device is a device for pressing a car to fix the car when the car is overturned on a car dumper, and is mainly applied to the existing C-shaped car dumper of enterprises such as ports, steel, energy and the like. The tipplers comprise end rings, top beams, side beams, platforms, a car pressing device, a car leaning device and the like.
At present, the pressing device of the C-shaped car dumper is divided into the following mechanisms: balanced beam type press, hook type press, hinge type press, etc.
The balance beam type pressing device is arranged above the vehicle, so that the shortage of large material accumulation amount exists; meanwhile, the oil cylinder and each hinge point are positioned in a blanking area, so that the maintenance cost is increased; and the car pressing stroke is limited by the overall dimension of the car dumper, and if the car dumper of the special dumping C80 adopts the balanced beam type car dumper, the overall dimension of the car dumper needs to be increased, so that the equipment cost is increased, and the car dumper is not economical.
In order to realize the action of the mechanism, the hook type car pressing device is generally arranged in a vertical guide groove. Due to the presence of the car rest between the side sill and the vehicle, the space is tight and the car rest side hook guide groove is usually joined to the car rest steel structure. The pressing coupler can perform pressing-down action only after the backup plate is required to extend out to be in contact with a vehicle. However, in order to protect the freight car from being damaged when the car dumper fixes the car, the railway department clearly stipulates that the operation sequence of the car pressing device and the car leaning device of the car dumper needs to be firstly to press the car and then to lean against the car, so the hook type car pressing device cannot meet the railway requirement.
The folding type vehicle pressing device has the advantages of simple structure, low manufacturing cost and the like, but when the folding type vehicle pressing device is suitable for different vehicle unloading requirements, due to the constraint of the structural form, the vehicle pressing force cannot be perpendicular to the vehicle, a horizontal component force is applied to the vehicle, the vehicle is not protected, and the larger the vehicle height difference is, the more obvious the horizontal component force is.
The pressure car forms have a disadvantage that the weight of the pressure car device must be borne by the oil cylinder, which wastes the power of the hydraulic system; and the weight of the final ballast device is applied to the vehicle, increasing the difficulty of controlling the ballast force to be no greater than 78KN/400mm in relation to the requirements of the railway.
In conclusion, it is necessary to develop a new pressing device.
