Abstract
The utility model relates to a lifting limit device for a stacking truck, which comprises a truck body, a door frame arranged at the front end of the truck body and a fork frame body. The fork frame body is movably arranged on the door frame and can vertically move along the door frame; a hydraulic system is also arranged in the truck body and comprises a solenoid valve, a hydraulic directional valve and a hydraulic oil cylinder; and a limit induction switch is arranged at the top of the door frame. The lifting limit device has the advantages that when the fork frame body in the lifting limit device is lifted to the top of the door frame, the limit induction switch is touched; the solenoid valve receives an output signal of the limit induction switch and is powered up; when the hydraulic directional valve is started, hydraulic oil is stopped entering the hydraulic oil cylinder, and the pressure in the hydraulic oil cylinder is controlled, so that the fork frame body is stably braked and stopped, is free from impact vibration and is convenient to operate; and moreover, the operation safety is ensured, and the potential safety hazards are eliminated.
Description
Technical field
The utility model relates to a kind of carrier-and-stacker, relates in particular to a kind of rising inhibiting device of carrier-and-stacker, belongs to the carrying vehicle technical field.
Background technology
Electronic carrier-and-stacker is a kind of handling machinery, and it has walking and promotes the function of goods.Carrier-and-stacker in the market is general when the pallet fork support body arrives carrier-and-stacker door frame top to adopt fixing dead system retaining with its stop.This stop mode can produce bigger impact endurance test shock in system retaining process, make mode of operation not steady, and carrier-and-stacker pallet fork support body rocks when the access goods, and is wayward, operation inconvenience, and can not guarantee safety of operation, there is potential safety hazard.
The utility model content
The utility model purpose is for the deficiency that overcomes prior art a kind of carrier-and-stacker rising inhibiting device that does not have the impact endurance test shock stop to be provided.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of carrier-and-stacker rising inhibiting device, and comprise car body, be arranged on door frame, the pallet fork support body of car body front end, said pallet fork support body is movably arranged on the door frame, can move up and down along door frame; Also be provided with hydraulic efficiency pressure system in the car body; Said hydraulic efficiency pressure system comprises electromagnetic valve, hydraulic directional control valve, hydraulic ram; Said door frame top is provided with the limit induction switch; Run into the limit induction switch during pallet fork support body rising door frame top, the limit induction switch sends signal and gives electromagnetic valve, and electromagnetic valve gets electric, and hydraulic directional control valve starts, modulated pressure oil cylinder internal pressure, the steady stop of pallet fork support body.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The carrier-and-stacker rising inhibiting device of the utility model scheme when the pallet fork support body rises to car body door frame top, is run into the limit induction switch; Electromagnetic valve receives the limit induction switch output signal and gets electricly, and hydraulic directional control valve starts, and stops hydraulic oil and gets into hydraulic ram; Controlled the hydraulic ram internal pressure, made the steady stop of pallet fork support body, no impact endurance test shock; Easy to operate, and guaranteed safety of operation, eliminated potential safety hazard.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the front view of the carrier-and-stacker rising inhibiting device of the utility model;
Accompanying drawing 2 is the control flow chart of the carrier-and-stacker rising inhibiting device of the utility model;
Wherein: 1, car body; 2, door frame; 3, pallet fork support body; 4, limit induction switch.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The carrier-and-stacker rising inhibiting device of the utility model scheme when the pallet fork support body rises to car body door frame top, is run into the limit induction switch; Electromagnetic valve receives the limit induction switch output signal and gets electricly, and hydraulic directional control valve starts, and stops hydraulic oil and gets into hydraulic ram; Controlled the hydraulic ram internal pressure, made the steady stop of pallet fork support body, no impact endurance test shock; Easy to operate, and guaranteed safety of operation, eliminated potential safety hazard.
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, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
