Abstract
The utility model relates to a small fast manual prop-lifting hydraulic pump for lifting underground hydraulic props in coal mines and the like, which comprises a manual lifter (1), a water feeder (2) and the like, wherein a one-way valve (3) is arranged in the water feeder (2), and the back end of the water feeder (2) is connected with a groundwater pipeline through a pipeline filter (4); the front end of the water feeder (2) is connected with the three-way valve of a hydraulic prop through a quick release coupling (5), and a high-pressure liquid replenishing hole (6) is arranged between the one-way valve (3) in the water feeder (2) and the quick release coupling (5); and the water feeder (2) is connected with the liquid outlet of the manual lifter (1) through the high-pressure liquid replenishing hole (6). Because of fully using the pressure of groundwater in the coal mines, the utility model has the characteristics of energy saving, consumption reduction, improved efficiency, reduced labor intensity of workers, and the like.
Description
One, technical field
The utility model is a kind of small-sized quick setting prop hydraulic hand-pump that underground hydraulic pressure pillar liftings such as colliery are used that is used for.
Two, background technique
The safety support of down-holes such as colliery generally all adopts hydraulic prop, and the lifting of hydraulic prop all realizes by the hand-operated lifting device.Present hand-operated lifting device is owing to can not use phreatic pressure, and therefore power consumption is high, and efficient is low, the labor strength height.In addition, need carry out gib and hydraulic prop is changed, keeped in repair,, need small-sized setting prop hydraulic hand-pump fast efficiently particularly in extreme terrain, location or little work surface in underground work.
Summary of the invention:
The purpose of this utility model is: provide a kind of and utilize the groundwater pressure under the coal mine to alleviate working strength of workers, increase work efficiency, cut down the consumption of energy.
The technical solution of the utility model is: the utility model includes hand-operated lifting device, water inlet device etc.Be provided with one-way valve in the water inlet device, the rear end of water inlet device is connected by in-line filter and underground water pipe, the front end of water inlet device is connected by the triple-use valve of quick release coupling and hydraulic prop, be provided with high pressure fluid infusion hole between one-way valve in the water inlet device and the quick release coupling, the water inlet device is connected by the liquid outlet of high pressure fluid infusion hole and hand-operated lifting device.
In use, the rear end of water inlet device of the present utility model is connected by in-line filter and underground water pipe, the front end of water inlet device is connected by the triple-use valve of quick release coupling and hydraulic prop.As everyone knows, underground water under coal mine is to have certain pressure, along with underground work face is overhead dark more, phreatic pressure is high more, generally, higher sometimes at 2～4Mpa, and the pressure of opening the hydraulic prop triple-use valve only needs 0.68Mpa, for the lifting supporting of general hydraulic prop, phreatic pressure just can be satisfied the demand.The underground water that is provided by underground water pipe is after filter filters by the road, and the triple-use valve feed flow that enters hydraulic prop through one-way valve, quick release coupling presses the pillar lifting to use again.At this moment, only need to mend into emulsifier to the water inlet device by the high pressure fluid infusion hole of water inlet device from the hand-operated lifting device, be mixed into emulsified liquid with underground water, feed flow presses the pillar lifting to use.And the lifting of working as hydraulic prop needs bigger pressure, when the phreatic pressure in down-hole can not be satisfied the demand, can replenish pressurization by handling the hand-operated lifting device.Because be provided with one-way valve in the water inlet device, the pressure emulsified liquid that the hand-operated lifting device replenishes can not enter the down-hole underground water pipe.
Because the utility model made full use of the phreatic pressure in colliery, thereby realize the purpose of saving energy and reduce the cost, raising the efficiency, also reduced working strength of workers.
Description of drawings:
Fig. 1 is the utility model schematic representation,
Fig. 2 is the plan view of Fig. 1.
Embodiment:
Accompanying drawing is an embodiment of the present utility model, and present embodiment includes hand-operated lifting device 1, water inlet device 2 etc.Be provided with one-way valve 3 in the water inlet device 2, the rear end of water inlet device 2 is connected by in-line filter 4 and underground water pipe, the front end of water inlet device 2 is connected by the quick release coupling 5 and the triple-use valve of hydraulic prop, be provided with high pressure fluid infusion hole 6 between one-way valve 3 in water inlet device 2 and the quick release coupling 5, water inlet device 2 is connected by the high pressure fluid infusion hole 6 and the liquid outlet of hand-operated lifting device 1.
High pressure fluid infusion hole 6 can be arranged between the front end of one-way valve 3 in the water device 2 into and water inlet device 2, also can be arranged on the one-way valve 3 and the pipeline between the quick release coupling 5 in the water device 2 into.The high pressure fluid infusion hole 6 of present embodiment is arranged on the one-way valve 3 and the pipeline between the quick release coupling 5 in the water device 2 into.
For carry, easy to use, the water inlet device 2 can be fixed on the hand-operated lifting device 1, as shown in drawings.
Because the utility model takes full advantage of the pressure of coal mine underground water, therefore have energy-saving and cost-reducing, raise the efficiency, reduce workman's the characteristics such as labour intensity.
