Abstract
The utility model relates to an electric piling car which comprises a car body, a gantry, a lifting framework and a pallet fork. The gantry is arranged on the front side of the car body, the gantry is a rectangular framework which is vertically arranged, the lifting framework is arranged on the gantry and can vertically slide along two vertical frames of the gantry, the pallet fork is arranged on the lifting framework, and an inductive switch is arranged at the bottom of the gantry; a hydraulic oil cylinder is arranged in the gantry; a piston rod is arranged in the hydraulic oil cylinder; the top of the piston rod is connected with the lifting framework; a hydraulic system is arranged in the car body and connected with the hydraulic oil cylinder; and the hydraulic system comprises an electromagnetic valve and a hydraulic reversing valve. During the descending process, the lifting framework touches the inductive switch, then the inductive switch sends signals to the hydraulic system, the electromagnetic valve and the hydraulic reversing switch are started, and the pressure of liquid in the hydraulic oil cylinder is slowly reduced so that the piston rod drives the lifting framework to slowly descend until the lifting framework is stably stopped. The electric piling car is stable, safe and capable of effectively eliminating impact shocks generated by an excessive speed of the lifting framework during the descending and stopping process.
Description
Technical field
The utility model relates to a kind of electronic carrier-and-stacker, and 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.
The utility model content
The utility model purpose is that 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 is provided for the deficiency that overcomes prior art.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of electronic carrier-and-stacker, comprise car body, door frame, lift frame and pallet fork, and said door frame is arranged on the front side of car body; Said door frame is the rectangular frame that is vertical setting; 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, and is 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 utility model compared with prior art has advantage:
The electronic carrier-and-stacker of the utility model; 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 the stationarity and the safety of the utility model, increased the service life of the utility model.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the perspective view of the electronic carrier-and-stacker of the utility model;
Accompanying drawing 2 is the control flow scheme drawing of the electronic carrier-and-stacker of the utility model;
Wherein: 1, car body; 2, door frame; 3, lift frame; 4, pallet fork; 5, inductive switch.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Like accompanying drawing 1, the described a kind of electronic carrier-and-stacker of the utility model shown in 2; Comprise car body 1, door frame 2, lift frame 3 and pallet fork 4; Said door frame 2 is arranged on the front side of car body 1, and said door frame 2 is for being the rectangular frame of vertical setting, and said door frame 2 is provided with the lift frame 3 that can slide up and down along its two vertical edges frame; On the said lift frame 3 pallet fork 4 is arranged, be provided with inductive switch 5 near on the said door frame 2; Be provided with the hydraulic ram (not shown) in the said door frame 2; Be provided with the piston rod (not shown) in the said hydraulic ram; The top of said piston rod links to each other with lift frame 3; Be provided with the hydraulic efficiency pressure system (not shown) in the said car body 1; 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 3 is in the decline process; Touch inducing switch 5, said inductive switch 5 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 3 and slowly descends up to steady stop.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The electronic carrier-and-stacker of the utility model; 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 the stationarity and the safety of the utility model, increased the service life of the utility model.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
