Abstract

The utility model discloses a bottom lifting device for a mine hydraulic support. The bottom lifting device comprises two sets of bottom lifting oil cylinders, wherein each bottom lifting oil cylinder is connected with a pump station, the two sets of bottom lifting oil cylinders stretch out and draw back synchronously and are distributed symmetrically relative to the axis of the hydraulic support, an oil cylinder base of each set of bottom lifting oil cylinder is hinged with the hydraulic support, the other end of each set of bottom lifting oil cylinder is hinged with a connection rod, the middle part of the connection rod is hinged, the other end of the connection rod faces towards the bottom surface, the bottom lifting oil cylinder drives the connection rod to move, the connection rod presses downwards towards the bottom surface when the bottom lifting oil cylinders stretches out, and the connection rod is far away from the bottom surface when the bottom lifting oil cylinders draws back. According to the bottom lifting device for the mine hydraulic support, a bottom lifting jack is arranged in an inclined way, the structure is simple, the installation and the maintenance are convenient, and the bottom lifting distance is large.

Description

A kind of mine hydraulic bracket bottom lifting device
Technical field
The utility model relates to a kind of mining equipment, especially a kind of mine hydraulic bracket bottom lifting device.
Background technology
The hydraulic prop mining equipment that is absolutely necessary is during especially for use in softer production face.Yet, along with deepening continuously of exploitation, need to adjust and pass hydraulic support, on soft production face, hydraulic support is difficult to cause being difficult to the hydraulic support adjustment from wherein extracting.But existing uplifting device complicated structure takes up room greatly, lifts the problems such as end distance is little.
Summary of the invention
The above problem that exists for overcoming existing uplifting device, the utility model provides a kind of mine hydraulic bracket bottom lifting device, this uplifting device is by to lift oil cylinder as power, bilateral symmetry distributes, have simple in structure, lift easily advantage.
For achieving the above object, the technical solution of the utility model is:
A kind of mine hydraulic bracket bottom lifting device, comprise and lift end oil cylinder, be connected with pumping plant with lifting end oil cylinder, the described end oil cylinder of lifting is two covers, and this two cover lifts oil cylinder synchronization telescope and symmetrical about the hydraulic support axis, the oil cylinder seat that every cover lifts oil cylinder is hinged on the hydraulic support, the other end is hinged with connecting rod, and the middle part of described connecting rod is hinged, and the other end of connecting rod is towards the bottom surface, lift end oil cylinder drivening rod action: when lifting the oil cylinder elongation, connecting rod presses down towards the bottom surface; When lifting the oil cylinder retraction, connecting rod is away from the bottom surface.
Described connecting rod is warp architecture, the maximum curvature location point of pin joint position, connecting rod middle part warp architecture.Described connecting rod is provided with base towards an end of bottom surface.
Operating principle of the present utility model and beneficial effect are:
This uplifting device is hinged with at hydraulic support and lifts end oil cylinder, lifts end oil cylinder and is provided with two cover bases and symmetrical, by the connecting rod hinged with it, realizes that connecting rod presses down towards the bottom surface when lifting the oil cylinder elongation, finishes and lifts end action; When lifting the oil cylinder retraction, connecting rod is finished and is packed up action away from the bottom surface, and floor space is little, and is simple in structure, lifts the end conveniently.
Adopt the bending structure with lifting the hinged connecting rod of end oil cylinder, can realize when lifting the little flexible scope of end oil cylinder and the contacting of StoreFront that remaining elongation all can be used for lifting end action, it is effective to lift the end.
End towards the bottom surface of connecting rod is provided with base, has increased the contact area with the bottom surface, and the lower limit that has reduced connecting rod in soft production face floats, and further optimizes and lifts effect.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, this device comprises lifts end oil cylinder 3, with lift end oil cylinder 3 and be connected with pumping plant, the described end oil cylinder 3 of lifting is two covers, and this two cover lifts oil cylinder synchronization telescope and symmetrical about the axis of hydraulic support 1, and the oil cylinder seat that every cover lifts oil cylinder 3 is hinged on the hydraulic support 1, the other end is hinged with connecting rod 2, described connecting rod 2 is warp architecture, and connecting rod 2 middle part pin joints are positioned at the maximum curvature location point place of warp architecture, and the other end of connecting rod 2 is towards the bottom surface and be provided with base.When lifting end oil cylinder 3 elongation, connecting rod 2 presses down towards the bottom surface; When lifting end oil cylinder 3 retraction, connecting rod 2 is away from the bottom surface.
During use, connecting rod 2 rotates the end of lifting of realizing hydraulic support around jointed shaft and moves under the effect of lifting end oil cylinder 3, has not only solved the difficult problem that Bracket in Thin Coal Seam can't be installed bottom lifting device, and have simple in structurely, be easy for installation and maintenance and lift the large characteristics of end distance.
