The utility model provides a pair of suspension hydraulic prop, the maximum height of pillar is 6 meters to make the pillar at the high seam, reach safety support's function when adopting the high comprehensive face end temporary support of adopting greatly.
Description
Technical field
The utility model relates to technical field of hydraulic pressure, especially a kind of suspension hydraulic prop being applicable to the temporary lining of thick seam large mining high comprehensive mining face end.
Background technology
The support apparatus of channel of coal mining working surface has the various structures such as wooden prop, elemental metals friction prop, hydraulic prop and two telescopic suspension supporting columns, in recent years, along with the continuous developmental research of engineers and technicians, support technology has had significant improvement, and being progressively tending towards perfect, wooden prop and elemental metals pillar seldom use; Hydraulic prop is the new product developed after elemental metals friction prop, existing extensive use, it have lightweight, stroke is large, the advantage such as pollution-free.But still there are some problems: the maximum height of hydraulic prop domestic is at present 4.5 meters, and the height of hydraulic support has reached 6 meters, 6.5 meters even, conventional monomer pillar height has been not suitable with the supporting requirement of modern mining industry, the way of usual employing top board cushioning, greatly reduces the safety of supporting.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome hydraulic prop insufficient height problem, the utility model provides a kind of suspension hydraulic prop, the maximum height of pillar is 6 meters, thus make pillar at high seam, reach the function of safety support during the fully-mechanized mining working faces end head temporary lining of high working face.
The utility model solves the technical scheme that its technical problem adopts: a kind of suspension hydraulic prop, comprise oil cylinder and one end hollow be arranged in oil cylinder to live post, hollow post alive becomes gap to arrange with oil cylinder, the lower end of oil cylinder is provided with the base for sealed cylinder, post upper end alive is provided with the seal cover for sealing post alive, seal cover upper end is provided with top cover, be positioned in the middle of the base inside oil cylinder and be provided with draw ring, be positioned in the middle of the seal cover inside post alive and be provided with draw ring, two draw rings are connected by back-moving spring, it is characterized in that: the sealing of described cylinder upper end place is fixed with handle body, described handle body is connected with post slipper seal of living, valve body is provided with in described handle body, described valve body is provided with the liquid injection hole being communicated with post cavity of living.
Particularly, described valve body is triple-use valve.
Particularly, described seal cover is positioned at inside wall place, post upper end alive.
The beneficial effects of the utility model are: the one suspension hydraulic prop that the utility model provides, and the maximum height of pillar is 6 meters, thus makes pillar at high seam, reach the function of safety support during the fully-mechanized mining working faces end head temporary lining of high working face; Hand handle and valve body are arranged to one, advantageously in the control of pillar, advantageously in safety support.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of a kind of hydraulic prop that suspends of the present utility model.
In figure: 1. top cover, 2. live post, 3. seal cover, 4. valve body, 5. handle body, 6. oil cylinder, 7. back-moving spring, 8. base, 9. draw ring, 10. liquid injection hole.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of suspension hydraulic prop, comprise oil cylinder 6 and one end hollow be arranged in oil cylinder 6 to live post 2, hollow post 2 alive is arranged with oil cylinder 6 one-tenth gap, the lower end of oil cylinder 6 is provided with the base 8 for sealed cylinder 6, post 2 upper end alive is provided with the seal cover 3 for sealing post 2 alive, seal cover 3 is positioned at inside wall place, post 2 upper end alive, seal cover 3 upper end is provided with top cover 1, be positioned in the middle of the base 8 inside oil cylinder 6 and be provided with draw ring 9, be positioned in the middle of the seal cover 3 inside post 2 alive and be provided with draw ring 9, two draw rings 9 are connected by back-moving spring 7, the sealing of oil cylinder 6 upper end is fixed with handle body 5, handle body 5 is connected with post 2 slipper seal of living, triple-use valve 4 is provided with in handle body 5, triple-use valve 4 is provided with the liquid injection hole 10 being communicated with post 2 cavity of living.
The course of work of this suspension hydraulic prop is: by triple-use valve 4 to fluid injection in post 2 of living, liquid enters in the cavity of post 2 alive by the liquid injection hole 10 of triple-use valve 4, along with the injection of liquid, when reaching certain pressure, live post 2, seal cover 3 and top cover 1 rises, supporting object when rising to certain altitude; When stroke arrives the stroke of regulation, namely reach pillar maximum height 6 meters, realize supporting object.When post falls in pillar, under the effect of back-moving spring 7, liquid leads to triple-use valve 7 by liquid injection hole 10 makes liquid discharge, and liquid often injects and discharges once, and post 2 of living just supports and falls post once, and such pillar just completes a working cycles.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to right.
