Description
Technical Field
The utility model belongs to the technical field of the colliery supporting equipment, belong to and relate to a unit support lifts by crane structure.
Background
The common support hoisting is generally provided with 4 or 2 hoisting points on a base, the hoisting points are required to be hooked during hoisting, hooks connected with a monorail crane are correspondingly increased, the hook efficiency is low, and the condition of deflection of a balance point can occur in the hoisting process, so that the stable hoisting is difficult; as shown in fig. 5 and 6, the layout of the 4 lifting points is schematically shown.
Disclosure of Invention
In order to overcome the shortcomings of the prior art, the utility model provides a unit type support lifting structure.
The utility model discloses a realize through following technical scheme: the utility model provides a unitized support lifts by crane structure, support top crossbeam is provided with heavy groove, sinks to be equipped with the lifting ring seat in the groove, and the lifting ring suit is in the lifting ring seat, and can be located heavy inslot completely after the lifting ring is kept flat, and the side of every support stand all is equipped with two liquid accuse check valves, and the support stand has the hydraulic fluid port in pole chamber and the hydraulic fluid port in support stand rodless chamber all to be connected with two liquid accuse check valves.
Furthermore, the suspension ring seat is fixed in a sinking groove of a cross beam at the top of the bracket through a screw.
Furthermore, the suspension ring seat is welded and fixed in a sinking groove of a cross beam at the top of the bracket.
Furthermore, the sinking groove is filled with rubber materials.
The utility model has the advantages that: a single lifting point is convenient to lift, and meanwhile, the lifting hook of the single-point lifting point can be out of the position right above the lifting point and can also lift when being slightly inclined, the gravity center can be automatically aligned, and the support can be conveniently moved out of the queue.

In the figure, 1, a cross beam at the top of a bracket 1-1, a sink groove 2, a suspension ring seat 3, a suspension ring 4, a bracket upright post 4-1, a liquid return port 4-2, a liquid inlet 5, a double-hydraulic control one-way valve 6 and rubber materials.
Detailed Description
The invention will be further explained below with reference to the drawings and examples.
As shown in fig. 1 to 4, a lifting structure of a unit type bracket is provided, wherein a cross beam 1 at the top of the bracket is provided with a sinking groove 1-1, a lifting ring seat 2 is arranged in the sinking groove 1-1, a lifting ring 3 is sleeved in the lifting ring seat 2, and as shown in fig. 3, the lifting ring 3 can be completely positioned in the sinking groove 1-1 after being horizontally placed, a front lifting hook is arranged on a base of the bracket, the lifting ring does not influence a bracket upright post 4 during lifting, the lifting ring 3 is arranged on the cross beam 1 at the top of the bracket, in order to prevent a column head of the bracket upright post 4 from being pulled out during lifting, a double hydraulic control check valve 5 is arranged on the side surface of each bracket upright post 4, and an oil port of a rod cavity of the bracket upright post 4 and an oil port of a rodless cavity of the. The double hydraulic control one-way valve 5 is added, namely a hydraulic control one-way valve is arranged on a liquid inlet 4-2 and a liquid return port 4-1 of the support stand column 4, the upper lifting ring 3 is lifted, namely the column head is passively pulled out, liquid in a rod cavity of the support stand column 4 is pressurized at the moment, if the one-way valve is not arranged at the moment, the liquid is discharged from the liquid return port 4-1, the column head is pulled out, the liquid return through the one-way valve cannot be discharged, and the column head cannot be pulled out.
Furthermore, the lifting ring seat 2 is fixed in a sinking groove 1-1 of the support top cross beam 1 through a screw, and during installation, the lifting ring 3 is firstly placed in an installation groove of the lifting ring seat, and then the lifting ring seat 2 is fastened in the sinking groove 1-1.
Furthermore, the lifting ring seat 2 is welded and fixed in a sinking groove 1-1 of the support top cross beam 1, when in installation, the lifting ring 3 is placed in an installation groove of the lifting ring seat, and then the lifting ring seat 2 and the support top cross beam 1 are welded and fastened.
furthermore, rubber materials 6 are filled in the sinking groove 1-1, when the cross beam 1 at the top of the support works and is pressed, the hanging ring 3 is pressed in the rubber materials, and when the support is in a non-working state, the hanging ring 3 is bounced to the upper surface of the rubber materials 6 by the elastic force of the rubber materials 6, so that the hanging is convenient to hook during the hoisting.
a single lifting point is convenient to lift, and meanwhile, the lifting hook of the single-point lifting point can be out of the position right above the lifting point and can also lift when being slightly inclined, the gravity center can be automatically aligned, and the support can be conveniently moved out of the queue.
