Abstract
The invention discloses a stacking car with a lifting and speed-limiting device, comprising a car body, a door frame, a lifting framework and a pallet fork; the door frame is arranged in the front side of the car body, and the door frame is a rectangular framework which is vertically arranged; the lifting framework which can slide vertically along two vertical side frames of the door frame is arranged on the door frame; the pallet fork is arranged on the lifting framework, a sensing and speed-limiting switch is arranged on the door frame close to the top of the door frame; a hydraulic cylinder is arranged in the door frame; a piston rod is arranged in the hydraulic cylinder; the top of the piston rod is connected with the lifting framework; a hydraulic system is arranged in the car body, and the hydraulic system is connected with the hydraulic cylinder; the hydraulic system comprises an electromagnetic valve and a hydraulic reversing valve; the lifting framework triggers the sensing and speed-limiting switch during the lifting process, and the sensing and speed-limiting switch sends a signal to the hydraulic system, the electromagnetic valve and the hydraulic reversing valve are started; and liquid pressure in the hydraulic cylinder is gradually increased to make the piston rod drive the lifting framework to gradually lift until smoothly stopping, thereby, the impact vibration can be effectively removed, and stability and safety can be guaranteed.
Description
Technical field
The present invention relates to a kind of carrier-and-stacker, particularly a kind of carrier-and-stacker with lifting speed-limit device belongs to the carrying vehicle technical field.
Background technology
In the tiered warehouse facility system, piler is used widely, is used for goods is taken out from the goods storehouse or puts into.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.In the lift frame lifting process, common employing is that fixing system retaining makes its stop when lift frame need be deposited goods, and the hoisting speed of lift frame does not reduce during owing to stop; But stop by force, lift frame just can produce impact endurance test shock, and the stability status of machinery can change; When unstable state is serious, can causes goods on pallet fork to be shaken and drop, even might cause carrier-and-stacker to be translated into; Cause unnecessary loss, exist potential safety hazard.
Summary of the invention
Technical matters to above-mentioned existence the objective of the invention is: proposed a kind of carrier-and-stacker that promotes speed-limit device that has that can effectively eliminate impact endurance test shock that lift frame produces because of excessive velocities when promoting stop.
Technical solution of the present invention is achieved in that a kind of carrier-and-stacker that promotes speed-limit device that has; 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 the induction speed limiting switch near the place, top 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 lifting process; Touch inducing speed limiting switch, said induction speed limiting switch send signal and give hydraulic efficiency pressure system, and said electromagnetic valve and hydraulic directional control valve start; Fluid pressure slowly increases in the said hydraulic ram, makes piston rod drive lift frame and slowly promotes up to steady stop.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Carrier-and-stacker with lifting speed-limit device of the present invention; Said lift frame is in lifting process, and touch inducing speed limiting switch, said induction speed limiting switch send signal and give hydraulic efficiency pressure system; Said electromagnetic valve and hydraulic directional control valve start; Fluid pressure slowly increases in the said hydraulic ram, makes piston rod drive lift frame and slowly promotes up to steady stop, has eliminated the impact endurance test shock that lift frame produces because of excessive velocities when promoting stop effectively; Improve stationarity of the present invention and safety, stopped potential safety hazard.
