The improvement is that a stop valve is connected to one of the plunger pumps in parallel. The gate-type bucket-wheel material piling-taking machine hoisting mechanism hydraulic system has the advantages that speed varying without halting in work of a movable beam hoisting mechanism is achieved, operating procedures for movable beam hoisting speed varying are reduced, and the work efficiency of a bucket wheel machine is improved.
Description
Technical field
The utility model belongs to mechanical field, is specifically related to the loose material of solid particle to the stacking of storage place or extracts the gantry stacker material taking machine of removing in Work machine.
Background technique
As Fig. 1, bag walking beam 1 shown in Fig. 2, roller mechanism 2, fixed beam 3, belt conveyer 4, rigid door leg 5, walking beam lifting mechanism 6, complete machine traveller 7, trailer 8, the door type bucket-wheel stacker reclaimer (hereinafter to be referred as gate-type bucket wheel machine) of flexible door leg 9, continuous as one, bulk material handling conveying equipment efficiently, due to it, to have back the rate of getting high, there is certain Blending Efficiency of Blending, stockpile is convenient to management, simple in structure, easy to operate and easily be automated the advantages such as control, be widely used in large-size thermal power plant, industrial and mining enterprise and harbour loose unpacked material bedding plant.
Walking beam lifting mechanism in gate-type bucket wheel machine is the chief component that gate-type bucket wheel machine is realized heap feeding function, effect is that the position change that drives walking beam to realize short transverse by external force coordinates roller mechanism simultaneously, the winding machine such as sealing-tape machine and trailer heap material extracting operation, its structure (consulting Fig. 3) comprises by gudgeon and is fixed on two plunger piston fluid pressure cylinders 13 in parallel in a leg column, be arranged on the hydraulic power unit 10 of rigid door inboard leg the whole series, be hinged on plunger cylinder head chain wheel set 12, sprocket wheel and heavy duty roller chain 14 engagement driving, wherein roller chain 14 one end are connected with walking beam, the other end is connected with column slideway, by hydraulic power unit 10 fuel feeding, drive oil hydraulic cylinder 13 linear telescopic motions, drive head sprocket wheel 12 engagement rolling in chain 14 length, chain 14 pulls walking beam 1 to move up and down in column slideway by guide wheel group, thereby realize the motion that hoists of walking beam short transverse.The lifting of walking beam flexible leg side adopts wire rope balance sysmte in addition, and steel cable adopts the separate work of double-steel wire rope.Its fag end is fixed on balancing pole, automatically to adjust the length of two wire rope, make its stressed equating, by wire rope and sheave block transmission, make counterweight trolley deadweight oppositely pull walking beam, give upwards lifting force of walking beam, to reduce the energy consumption of oil cylinder load force and Hydraulic system with hoisting Mechanism.
Principle as shown in Figure 4 for existing gate-type bucket wheel machine Hydraulic system with hoisting Mechanism (pumping plant and plunger piston fluid pressure cylinder).Composition member has plunger pump 15-1 and 15-2, relief valve 16-1 and 16-2, one-way valve 17-1 and 17-2, electro-hydraulic reversing valve 18, hydraulic lock 19, one-way throttle valve 20-1 and 20-2, plunger piston fluid pressure cylinder 13-1 and 13-2, annexation is that one-way valve connects plunger pump output terminal, one-way valve output termination relief valve and electro-hydraulic reversing valve, electro-hydraulic reversing valve output termination hydraulic lock, hydraulic lock output connects two one-way throttle valves in parallel, one-way throttle valve output termination plunger cylinder.The shortcoming that above-mentioned hydraulic system exists has: adopt two quantitative plunger oil pump feeds; low cruise list pump startup, high speed operation double pump starts, but speed change cannot realize at work; because plunger pump does not allow band to carry, start, therefore must shutdown just can realize speed change in the process of hoisting.Cause work procedure loaded down with trivial details, affect equipment working efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of door type bucket-wheel stacker reclaimer Hydraulic system with hoisting Mechanism of realizing variable-speed operation, overcomes the deficiency that existing hydraulic system need first be shut down when accelerating to walking beam.
Hydraulic system of the present utility model comprises two plunger pumps arranged side by side, connect two protection one-way valves of plunger pump output terminal, connect two one-way valve output terminals merge after the relief valves of two on pipelines and a 3-position 4-way electro-hydraulic reversing valve, the hydraulic lock that is connected electro-hydraulic reversing valve output terminal, two one-way throttle valves in parallel of connection hydraulic lock output terminal, two plunger cases arranged side by side of two throttle valve output terminals of connection, the improvement of doing is: one of them plunger pump is parallel with shut off valve.
The working principle of improvement part is: when being parallel with the plunger pump initial start of shut off valve, because shut off valve branch road resistance is very little, now pump running sucking-off fluid returns to fuel tank by shut off valve branch road.Along with the continuity fluid flow of starting time increases gradually, when reaching the flow of shut off valve setting, shut off valve commutation, this branch road blocks, and realizes the No Load Start of this pump, participates in the lifting to walking beam.
The beneficial effects of the utility model are: realize in the work of walking beam lifting mechanism and do not shut down speed change, reduced the hoist programmed sequence of operations of speed change of walking beam, improved the working efficiency of bucket wheel machine.
