Abstract
The utility model relates to a hydraulic controlled hoist ratchet lock-up device, belonging to a hoist ratchet locking device for cranes. The amplitude changing hoist is connected with a support below. The pawl is fixed on the support through pins. One end of the pawl is positioned on the track of the amplitude changing hoist, while the other end is connected with the support through an oil tank which is connected with a hydraulic controller. The utility model can connect the ratchet lock-up controlling system with the hoist oil line based on the actual situations of operations. When the controlling hoist moves, the ratchet lock-up device can be automatically opened. When the movement stops and the hoist needs locking, the ratchet can be driven to reset by the oil tank by operating the switches, thus the hoist can be locked to prevent dropping. The utility model has the advantages of changing manual operation into automatic operation, improving operating comfort, convenient operation, and having high reliable and practical properties.
Description
Technical field
The utility model relates to a kind of elevator ratchet Locking Device of hoist, particularly a kind of hydraulic control elevator ratchet Locking Device.
Background technique
At present, in order to guarantee the crawler crane work safety, the luffing elevator all has the ratchet Locking Device, and crawler crane elevator ratchet Locking Device is to be connected with ratchet by backguy or linkage mechanism, and ratchet is stuck on the ratchet, constitutes the ratchet Locking Device.Adopt manually control backguy or linkage mechanism control elevator ratchet Locking Device, can not control automatically, if manually control untimelyly, may cause the elevator rotation of winch to become the arm rotation that falls, arm is out of control to have an accident thereby make.
Summary of the invention
The purpose of this utility model is that a kind of hydraulic control elevator ratchet Locking Device that can control ratchet automatically will be provided.
The purpose of this utility model is achieved in that the below of luffing elevator is connected with support, ratchet by dowel fixes on support, one end of ratchet is positioned on the track of luffing elevator, is connected with oil cylinder between the other end and the support, and oil cylinder is connected with hydraulic controller.
Hydraulic controller has an oil cylinder, one end of oil cylinder is connected with one-way valve by electromagnetic valve I, one end of the other end of oil cylinder and solenoid valve connects oil sump simultaneously, the other end of electromagnetic valve I is connected with 2 ends of break oil cylinder and reduction valve simultaneously, 3 ends of reduction valve with connect oil sump after 3 ends of oil hydraulic motor are connected, 1 of reduction valve is connected with 3 ends of shuttle valve, the 1 end while and the one-way valve II of shuttle valve, the end of one-way valve III is connected with the end A that hoists, the 2 ends while of shuttle valve and the end of one-way valve IV, 4 ends of equilibrium valve and 2 ends, 2 ends of oil hydraulic motor are connected with the end B that descends, the other end of one-way valve III and one-way valve IV is connected with 3 ends of equilibrium valve simultaneously, and the other end of one-way valve II is connected with 1 end of equilibrium valve and 1 end of oil hydraulic motor simultaneously.
Beneficial effect: owing to adopt such scheme, this hydraulic control elevator ratchet Locking Device, the actual conditions according to operation are connected ratchet locking control system with the elevator oil circuit, when handling the elevator action, the ratchet Locking Device can be opened automatically, stops to move when needing the locking elevator, can pass through operating switch, making oil cylinder drive ratchet resets, thereby the locking elevator prevents from, and has reached the purpose of this utility model.This elevator ratchet Locking Device becomes automatic operation with manually-operable, has improved operation comfort, and is easy and simple to handle, reliable, practical.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is the structural drawing of the utility model hydraulic controller.
Embodiment
Embodiment 1: luffing elevator 1 is that the below of ratchet is connected with support 3, and ratchet 2 is fixed on the support 3 by pin 4, and an end of ratchet 2 is positioned on the track of luffing elevator 1, is connected with oil cylinder G between the other end and the support 3, and oil cylinder G is connected with hydraulic controller.
Hydraulic controller has an oil cylinder G, the end of oil cylinder G is connected with one-way valve I by solenoid valve Y, the end of the other end of oil cylinder G and solenoid valve Y connects oil sump simultaneously, the other end of electromagnetic valve I is connected with 2 ends of break oil cylinder Z and reduction valve J simultaneously, 3 ends of reduction valve J with connect oil sump after 3 ends of oil hydraulic motor M are connected, 1 of reduction valve J is connected with 3 ends of shuttle valve S, 1 end while and the one-way valve II of shuttle valve S, the end of one-way valve III is connected with the end A that hoists, the 2 ends while of shuttle valve S and the end of one-way valve IV, 4 ends of equilibrium valve P and 2 ends, 2 ends of oil hydraulic motor M are connected with the end B that descends, the other end of one-way valve III and one-way valve IV is connected with 3 ends of equilibrium valve P simultaneously, and the other end of one-way valve II is connected with 1 end of equilibrium valve P and 1 end of oil hydraulic motor M simultaneously.
Luffing elevator, ratchet and oil cylinder are fixed on the support, need elevator to hoist or when descending, A mouth or B mouth advance pressure oil, pressure oil just enters reduction valve J by shuttle valve S, after reduction valve J decompression, Y enters oil cylinder by solenoid valve, the piston rod withdrawal of oil cylinder, drive ratchet away from elevator, but the elevator normal rotation.One-way valve is closed the rod chamber of oil cylinder, makes ratchet be in disengaged condition all the time, guarantees the elevator Normal Takeoff and Landing.Only need stop the elevator action when needing the locking elevator to prevent to descend, and it is electric to allow solenoid valve Y get, and makes the oil of the rod chamber of oil cylinder return case, the piston rod of oil cylinder drives ratchet near elevator because the effect of Returnning spring is stretched out, thereby reaches the purpose of locking elevator.
Claims (2)
