Abstract
The utility model discloses a kind of hydraulic support bottom lifting device, including hydraulic jack, the cylinder barrel of hydraulic jack is vertically fixedly mounted in base, its lever is the most just to push rod center, described base is fixedly connected in the middle part of hydraulic chock footing gap bridge front end face, and lever can be resisted against on push rod upper surface after stretching out.This utility model uses hydraulic jack to be vertically installed on base bridge, after using oil cylinder flexible, hydraulic support is lifted, avoid pricking seriously under hydraulic support, thus facilitate tension and the movement of hydraulic support, production efficiency is greatly improved, and safety is obviously improved, and lifts because using oil cylinder to support, also reducing operator, this utility model also has simple in construction, low cost, feature efficiently easy to maintenance.
Description
Technical field
This utility model relates to a kind of hydraulic support bottom lifting device, belongs to hydraulic support technical field.
Background technology
Hydraulic support in use because of ore bed softer time, it may occur that prick serious situation under hydraulic support, particularly
When base plate is softer, lifting the end inconvenient, it has not been convenient to the tension of hydraulic support and movement, production efficiency is low, and safety is the poorest, it is desirable to
Operator are many.
Summary of the invention
The technical problems to be solved in the utility model is: provides a kind of hydraulic support bottom lifting device, is lifted by hydraulic support,
Being beneficial to movement and the tension of hydraulic support, production efficiency improves, and safety is obviously improved, and decreases operator, existing to solve
There is problem present in technology.
The technical scheme that this utility model is taked is: a kind of hydraulic support bottom lifting device, including hydraulic jack, hydraulic jack
Cylinder barrel be vertically fixedly mounted in base, its lever is the most just to push rod center, and described base is fixedly connected on hydraulic support
In the middle part of base bridge front end face, lever can be resisted against on push rod upper surface after stretching out.
Preferably, above-mentioned base includes that the connecting plate being welded on base bridge is fixed in guide cylinder and both sides, on guide cylinder
End is provided with connecting pin.
Preferably, it is provided with a plurality of reinforcement in above-mentioned connecting plate.
Preferably, above-mentioned connecting pin is installed guide cylinder barrel and is provided with securing plate, and described securing plate uses two halves arc plate
It is welded on guide cylinder barrel.
The beneficial effects of the utility model: compared with prior art, this utility model uses hydraulic jack to be vertically installed at
On base bridge, after using oil cylinder flexible, hydraulic support is lifted, it is to avoid prick serious under hydraulic support, thus facilitate hydraulic support
Tension and movement, production efficiency is greatly improved, and safety is obviously improved, because of use oil cylinder support lift, also reduce operation
Personnel, this utility model also has simple in construction, low cost, feature efficiently easy to maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is plan structure schematic diagram of the present utility model.
In figure, 1-hydraulic jack, 2-cylinder barrel, 3-base, 4-base bridge, 5-lever, 6-push rod, 7-guide cylinder, 8-is even
Fishplate bar, 9-connecting pin, 10-reinforcement, 11-securing plate, 12-comes directly towards, 13-bearing pin.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described further by specific embodiment.
Embodiment 1: as shown in Figure 1-2, a kind of hydraulic support bottom lifting device, including hydraulic jack 1, the cylinder of hydraulic jack 1
Cylinder 2 is vertically fixedly mounted in base 3, and its lever 5 is the most just to push rod 6 center, and arranges detachable bearing pin in lever 5 end
13 tops 12 connected, are resisted against on push rod 6 by top 12, increase contact area, and unit are bearing capacity reduces, base 3
Being fixedly connected in the middle part of hydraulic chock footing gap bridge 4 front end face, lever 5 can be resisted against on push rod 6 upper surface after stretching out.
Preferably, above-mentioned base 3 includes that the connecting plate 8 being welded on base bridge 4 is fixed in guide cylinder 7 and both sides, guides
Cylinder 7 upper ends are provided with connecting pin 9.
Preferably, it is provided with a plurality of reinforcement 10 in above-mentioned connecting plate 8.
Preferably, above-mentioned connecting pin 9 is installed guide cylinder 7 barrel and is provided with securing plate 11, and securing plate 11 uses two halves circular arc
Sheet is welded on guide cylinder 7 barrel.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model does not limit to
In this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in change
Or replace, all should contain within protection domain of the present utility model, therefore, protection domain of the present utility model should be with described power
The protection domain that profit requires is as the criterion.
