Further, the cylinder diameter of first cylinder and the second cylinder is more than the cylinder diameter of third cylinder and the 4th cylinder.
Two cylinders its structure that the two horizontally arranged cylinders and vertical direction are arranged is identical, is piston rod and cylinder barrel group
At a rod chamber and a rodless cavity two-chamber telescopic hydraulic cylinder；Described horizontally arranged its performance parameter of two cylinders is identical, institute
The performance parameter of two cylinders of the vertical direction stated is identical, when stroke and initial occupy-place ratio require larger, by increasing vertical two
Cylinder angle realizes that the cylinder diameter of two cylinder of level should be greater than the cylinder diameter of vertical two cylinder at this time；It is needed in the movement locus for playing hanging object lifting
When, the flow of vertical two cylinder can be entered by change to realize.
The present invention is generated compared with the existing technology to be had the beneficial effect that.
The present invention hingedly forms one four company's shape by the oil cylinder and slinging beam of horizontal and vertical setting, when removing pressure stretch contracting
It can be changed by four company's shape shapes of flexible direct drive of cylinder while hanging object having been made to lift, total lifting travel can substantially exceed
The stroke of ordinary cylinder elevating mechanism；It is more suitable for carrying out lift work in subsurface environment.The configuration of the present invention is simple, it is at low cost, and
Be capable of providing Bidirectional power, it is easy to use, can also by increase the cylinder diameter of two cylinder of level and be arranged vertical two cylinder it is different compared with
Inbound traffics are to adapt to the demand of special operation condition.

Specific implementation mode
In order to make technical problems, technical solutions and advantages to be solved be more clearly understood, in conjunction with reality
Example and attached drawing are applied, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only used to
It explains the present invention, is not intended to limit the present invention.With reference to embodiment and the attached drawing technical solution that the present invention will be described in detail, but
Protection domain is not limited by this.
As shown in Figure 1, a kind of four cylinder lifting gears for mine underground work, including the first horizontally arranged cylinder 11
The third cylinder 21 and the 4th cylinder 22 set up with the second cylinder 12, Vertical Square, slinging beam 3, hook 4, installation base plate 5 are led
To baffle 6, the reversal valve 7 of 3-position 4-way type, synchronous valve 8, hydraulic power unit 9；One end of first cylinder 11 and the second cylinder 12 respectively and
Two 5 phases of installation base plate are fixed, and the piston rod head of the first cylinder 11 is hinged with the cylinder bottom of third cylinder 21, the piston rod head of the second cylinder 12
Hinged with the cylinder bottom of the 4th cylinder 22, the piston rod head of third cylinder 21 and the 4th cylinder 22 is hinged with the both ends of slinging beam 3 respectively；It rises
The middle part for hanging crossbeam 3 is provided with hook 4, and the first cylinder 11, the second cylinder 12, third cylinder 21, the 4th cylinder 22 pass through hydraulic tube respectively
Successively with synchronous valve 8, reversal valve 7, hydraulic power unit 9 is in series.First cylinder 11, the second cylinder 12, third cylinder 21 and the 4th cylinder 22 are
Hydraulically extensible cylinder, there are one rod chamber and a rodless cavities for the tool of hydraulically extensible cylinder.The cylinder diameter of first cylinder 11 and the second cylinder 12 is big
In the cylinder diameter of third cylinder 21 and the 4th cylinder 22.
When the cylinder mouth of horizontally arranged first cylinder 11 and the second cylinder 12 is opposite, cylinder bottom is opposite, and axis is in line
It is horizontally fixed on 5 on installation base plate, the third cylinder 21 and 22 cylinder bottom of the 4th cylinder of vertical direction setting are downward, and cylinder mouth is upward and interior
Receipts form an angle；Horizontally disposed and vertically disposed four fluid cylinders the high pressure hard tube and three position four-way directional control valve 7, it is synchronous
Valve 8 is connected with hydraulic power unit 9 again after connecting, and provides hydraulic power by hydraulic power unit 9, three position four-way directional control valve 7 manipulates, synchronous valve
8 controls make four hydraulic cylinder safety and steady work, have realized the lifting of hanging object.
The first horizontally arranged cylinder 11 is identical with the performance parameter of the second cylinder 12, the third cylinder 21 of vertical direction setting
It is identical with the performance parameter of the 4th cylinder 22, in stroke and bigger initial occupy-place, by two cylinders for increasing vertical direction setting
Angle realize, while increasing the cylinder diameter of two horizontally arranged cylinders；The angle of two cylinders of vertical direction setting is bigger, horizontal
The cylinder diameter of two cylinders of direction setting is also bigger, and when the movement locus of hanging object lifting needs, the stream of vertical two cylinder is entered by change
It measures to realize.
The specific course of work is, as shown in Figure 1, when playing a hanging object and needing to increase, the manipulation hand of three position four-way directional control valve 7
Handle is put into the position of " liter ", and highly pressurised liquid enters the rodless cavity of horizontally arranged the first cylinder 11 and the second cylinder 12, pushes and lives
Plug makes piston rod relative extension simultaneously, the angle of the axis of third cylinder 21 and the 4th cylinder 22 that vertical direction is arranged become smaller, and makes height
Press liquid enters the rodless cavity of the third cylinder 21 and the 4th cylinder 22 of vertical direction setting, its piston is pushed to keep piston protruding straight
It picks up dynamic hanging object to increase, raising while, which also returns, makes axis angle become smaller, and has made hanging object raising, conversely, under such as needing hanging object
When drop, the control crank of three position four-way directional control valve 7 is put into the position of " drop ", and highly pressurised liquid enters the rod chamber of four cylinders, reversely
It pushes piston that piston rod is made to retract, has directly made hanging object raising or the third cylinder 21 being arranged by vertical direction and the 4th cylinder 22
Angle, which becomes smaller, has made hanging object increase.
The above content is combine specific preferred embodiment to the further description done of the present invention, and it cannot be said that
The specific implementation mode of the present invention is only limitted to this, for those of ordinary skill in the art to which the present invention belongs, is not taking off
Under the premise of from the present invention, several simple deduction or replace can also be made, all shall be regarded as belonging to the present invention by being submitted
Claims determine scope of patent protection.
