Abstract
The invention discloses an electric piling car, which comprises a piling car body, a portal frame, a lifting frame and forks. The portal frame is arranged on the front side of the piling car body and is a rectangular frame arranged vertically, the lifting frame capable of sliding vertically along two vertical edges of the portal frame is arranged on the portal frame, the forks are arranged on the lifting frame, and a sensing switch is arranged at the bottom of the portal frame. A hydraulic oil cylinder is arranged in the portal frame, a piston rod is arranged in the hydraulic oil cylinder, the top of the piston rod is connected with the lifting frame, and a hydraulic system is arranged in the piling car body and connected with the hydraulic oil cylinder and comprises an electromagnetic valve and a hydraulic reversing valve. During descending of the lifting frame, the sensing switch is triggered and sends out signals to the hydraulic system, the electromagnetic valve and the hydraulic reversing valve are started, and pressure of oil in the hydraulic oil cylinder is reduced slowly, so that the piston rod drives the lifting frame to descend slowly to brake stably. By the electric piling car, impact shock caused by overhigh speed during descending and braking of the lifting frame is effectively eliminated, so that the lifting frame is stable and safe.
Description
Technical field
The present invention relates to a kind of electronic carrier-and-stacker, the particularly a kind of electronic carrier-and-stacker that can effectively eliminate lift frame at the impact endurance test shock of descending system stopping time generation belongs to the carrying vehicle technical field.
Background technology
In the tiered warehouse facility system, carrier-and-stacker is used widely.Carrier-and-stacker is meant the various wheeled carrying vehicle that the member pallet cargo is loaded and unloaded, piles height, stacking and short-distance transportation operation.Carrier-and-stacker generally comprises car body, door frame, lift frame and pallet fork; Said door frame is arranged on the front side of car body; Said door frame is the rectangular frame that is vertical setting, and said door frame is provided with the lift frame that can slide up and down along its two vertical edges frame, on the said lift frame pallet fork is arranged.Carrier-and-stacker drives through lift frame mainly at the operational process that picks and places goods that pallet fork realizes along the lifting moving of two vertical edge frames of door frame.What when goods need be deposited in the bottom that lift frame drops to door frame, mainly adopt is that fixing system retaining is with its stop; Because speed did not reduce when lift frame moved to the bottom of door frame; With its by force stop can produce impact endurance test shock; The goods of pallet fork possibly fallen by shake, and the carrier-and-stacker mode of operation is steady inadequately, if carrier-and-stacker is in the service life that this state can reduce carrier-and-stacker greatly for a long time.
Summary of the invention
Technical matters to above-mentioned existence the objective of the invention is: proposed a kind of electronic carrier-and-stacker that can effectively eliminate the impact endurance test shock that lift frame produces because of excessive velocities in the descending system stopping time.
Technical solution of the present invention is achieved in that a kind of electronic carrier-and-stacker; Comprise car body, door frame, lift frame and pallet fork; Said door frame is arranged on the front side of car body, and said door frame is the rectangular frame that is vertical setting, and said door frame is provided with the lift frame that can slide up and down along its two vertical edges frame; On the said lift frame pallet fork is arranged, be provided with inductive switch near on the said door frame; Be provided with hydraulic ram in the said door frame; Be provided with piston rod in the said hydraulic ram; The top of said piston rod links to each other with lift frame; Be provided with hydraulic efficiency pressure system in the said car body; Said hydraulic efficiency pressure system links to each other with hydraulic ram; Said hydraulic efficiency pressure system comprises electromagnetic valve and hydraulic directional control valve; Said lift frame is in the decline process; Touch inducing switch, said inductive switch send signal and give hydraulic efficiency pressure system, and said electromagnetic valve and hydraulic directional control valve start; Fluid pressure slowly reduces in the said hydraulic ram, makes piston rod drive lift frame and slowly descends up to steady stop.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Electronic carrier-and-stacker of the present invention; When lift frame touch inducing switch during near the door frame bottom; Said inductive switch sends signal and gives hydraulic efficiency pressure system, and said electromagnetic valve and hydraulic directional control valve start, and fluid pressure slowly reduces in the said hydraulic ram; Making piston rod drive lift frame slowly descends up to steady stop; Eliminated effectively lift frame the descending system stopping time because of the impact endurance test shock that excessive velocities produces, improved stationarity of the present invention and safety, increased service life of the present invention.
