Abstract
The utility model relates to a kind of detaching hydraulic support instrument, specifically a kind of hydraulic support valve group extracting tool.Comprise handle, the steel pipe of vertical welding in the middle part of handle, described steel pipe working end is welded with two hand-drawn wires vertically, and two hand-drawn wires are positioned at the same diameter two ends of steel pipe and the mouth grafting corresponding to valve group valve core case of its end coordinates.Hydraulic support valve described in the utility model assembling and dismantling are unloaded tool construction novelty, are skillfully constructed, and solve in the problem of producing and being difficult to during service valve group in maintenance process dismounting, simple to operate, are applicable to the dismounting of various hydraulic support valve group.
Description
Technical field
The utility model relates to a kind of detaching hydraulic support instrument, specifically a kind of hydraulic support valve group extracting tool.
Background technology
Along with the fast development of coal mining enterprise, hydraulic support in coal mining enterprise down-hole because there being support capacity safely and efficiently, and widely apply at big-and-middle-sized underground coal mine, but because digging tunnel affects by geological conditions, due to the factor such as pressure and water quality, cause valve group because of sealing, valve seat damage and be difficult to detachable maintaining after altering liquid.Do not have when service valve group the extracting tool of specialty to be difficult to take valve group spool apart maintenance, in service work, usually there is no the instrument of specialty, and affect several hours.Bring inconvenience greatly and difficulty to daily maintaining, cause huge hidden danger to personal safety and safety in production.
Summary of the invention
The utility model, in order to not have the extracting tool of specialty when solving service valve group, provides a kind of hydraulic support valve group extracting tool.
The utility model is achieved through the following technical solutions: hydraulic support valve group extracting tool, comprise handle, the steel pipe of vertical welding in the middle part of handle, described steel pipe working end is welded with two hand-drawn wires vertically, and two hand-drawn wires are positioned at the same diameter two ends of steel pipe and the mouth grafting corresponding to valve group valve core case of its end coordinates.
During concrete use, hold handle and the end of two hand-drawn wires of hydraulic support valve group extracting tool described in the utility model is plugged in the corresponding mouth of hydraulic support valve group valve core case, be rotated counterclockwise and just easily can open spool; Valve core case is tightened clockwise after maintenance heel changes sealing ring and spool.
Hydraulic support valve described in the utility model assembling and dismantling are unloaded tool construction novelty, are skillfully constructed, and solve in the problem of producing and being difficult to during service valve group in maintenance process dismounting, simple to operate, are applicable to the dismounting of various hydraulic support valve group.
Accompanying drawing explanation
Fig. 1 is the structural representation of hydraulic support valve group extracting tool described in the utility model.
In figure: 1-handle, 2-steel pipe, 3-hand-drawn wire.
Detailed description of the invention
Hydraulic support valve group extracting tool, comprise handle 1, the steel pipe 2 of vertical welding in the middle part of handle 1, described steel pipe 2 working end is welded with two hand-drawn wires, 3, two hand-drawn wires 3 vertically and is positioned at the same diameter two ends of steel pipe 2 and the mouth grafting corresponding to valve group valve core case of its end coordinates.
During concrete enforcement, according to the model of valve group valve core case, described steel pipe 2 adopts 6 of 200mm points of steel pipe manufacturings to form, and hand-drawn wire 3 adopts No. 10 hand-drawn wires to be made.After steel pipe 2 and handle 1 weld, hand-drawn wire 3 welds aftershaping with steel pipe 2, have to pass through quenching, polishing, add strong hardness.
