technical field

The invention relates to a vehicle handling stacker in the technical field of transportation, in particular to a scissor type vehicle handling stacker with a lateral movement pick-up and delivery device.

Background technique

At present, in the technical fields of various forms and series of raceway storage type mechanical parking equipment and parking systems that use unpowered cylindrical vehicle support raceways to store vehicles, each has its own advantages such as large vehicle storage capacity, small footprint, and simple structure. Low cost, short access time for vehicles, reliable operation and high efficiency, the increase in vehicle storage capacity can be achieved by increasing the number of parking floors of warehouse racks in the vertical direction and increasing the length of the roadway in the vertical direction to arrange parking spaces. However, for those applications where the storage capacity does not need to be large, the floor height of the parking equipment is limited due to some other reasons, and the construction period is short and the investment is small, such as the construction height of the parking equipment should be coordinated with the surrounding low-rise buildings, etc. , what is more needed and paid more attention to is that the structure of the parking equipment is simpler, the construction and equipment installation are easier, the cost of the unit parking space is lower, and the technology must be equally advanced. It is suitable for the vehicle handling stacker of this kind of small and medium-capacity roadway stacking type roller storage type mechanical parking equipment with the characteristics of low number of floors and low height, that is, roadway stacking crane or bridge crane. In the implementation of the vertical lifting movement of the crane, the hoisting and traction machine equipment in the form of an elevator installed on the top of the stacking crane and the corresponding steel wire rope, the lifting guide rail of the vehicle carrier on the steel frame of the stacking crane are mostly used; The hoisting hoist equipment in the form of an elevator at the bottom of the stacking crane, but still use supporting equipment such as a wire rope reel or pulley block installed on the top of the stacking crane and corresponding wire ropes, vehicle carrier lifting guide rails.

After searching the existing technical documents, it is found that the Chinese application number is: 200610118128.3, and the name is: a vehicle handling stacker with a vehicle pick-up and delivery mechanism. Constraint guide wheels, vehicle carrier, wheel support raceway, vehicle pick-up and delivery lateral movement mechanism, positioning actuation rod; the bottom and upper part of the stacker body are respectively equipped with drive travel wheels and restraint guide wheels, which can move longitudinally along the roadway, and the vehicle handling The machine lifts and moves vertically in the stacker machine body. Continuous unpowered front and rear wheel support raceways are arranged horizontally on the carrier, on which the transported vehicles are supported longitudinally, and the front and rear wheel support raceways are set between The vehicle pick-up and delivery lateral movement mechanism that can move horizontally in both left and right directions. The mechanism is equipped with a set of positioning actuating rods that can be rotated, opened, positioned or retracted. while pushing the vehicle". Although this technical scheme has a simple and reasonable structure, centralized and complete functions, and can be used as a transportation device for storage and retrieval of vehicles on the raceway, it can be used between the stacker body, the upper restraint guide wheels, and the vehicle carrier. It can be seen that not only the technology still belongs to the above-mentioned traditional technology, but also the existence of the restraint guide wheel must be equipped with the upper guide rail in the parking equipment, so the overall volume of the vehicle handling stacker is huge and complex, and the height of the equipment structure is equivalent to that of the parking equipment. At present, in the current implementation, it is necessary to use the hoisting tractor equipment in the form of an elevator installed on the upper part of the vehicle handling stacker and the corresponding steel wire ropes, vertical lifting carrier guide rails and other supporting equipment, in order to technically realize the lifting of the vehicle handling in it. Even if the hoisting hoist equipment in the form of an elevator installed at the lower part of the vehicle handling stacker is used, the wire rope reel or pulley block and the corresponding wire rope and vertical lifting mechanism installed on the upper part of the vehicle handling stacker are still used. Ancillary equipment such as carrier guide rails. The construction investment of this set of huge and complex equipment is still high, and in this case, because the height of the vehicle handling stacker itself in the parking equipment is limited, it is actually difficult to reach more than ten floors and tens of meters, so the vehicle handling stacking The carrier of the elevator form in the machine can not embody the advantage of long-distance vertical lifting of the vehicle. And the used carrier of all kinds of mechanical parking equipment vehicle handling stacker vertical lift vehicle at present, except above-mentioned elevator " hoisting form ", wire rope or chain suspension traction, do not see the technology of other structural forms.
