Abstract
The utility model relates to a direct reading type pressure measuring device for mine hydraulic support, and is formed by the improvement of the existing pressure measuring device. The utility model is characterized in that the outside of the upper half part of a casing has number and scale label, the pressure in the vertical cylinder of the hydraulic support can be indicated through the move of an indicating coat on the outside of the casing. The utility model has the advantages of convenient reading, high accuracy, simple structure, firm and durable structure, and convenient installation and maintenance.
Description
The utility model belongs to the fluid pressure detecting instrument, is mainly used in the pressure detecting of mine hydraulic support (pillar), is the improvement to original pressure detector.
The application number of the applicant's application is 92227227 mechanical pressure detector, mainly form by parts such as housing, pressure display pole, spring, joints, its pressure reading is to read by the cannelure that is engraved on the pressure display pole, find that after practicality this reading mode intuitive is poor, read very inconveniently, and indicating arm is exposed at the easy dirty rapid wear in housing outside.
The utility model improves above-mentioned pressure detector, and purpose is to make operating personnel's convenient reading, improves accuracy of reading, guarantees to use reliable.
Its technical scheme is that connection one indication cover is indicated and overlapped the first half that also is enclosed within housing in the lump on the indicating arm of original detector, can be with lifting lifting on shell of pressure indicating arm; Have numeral or scale sign in the casing upper half outside, when the pressure indicating arm rose, the indication cover rose together, exposes numeral or scale on the housing, is the force value that will read.
The utility model has the advantages that simple in structure, convenient reading, the accuracy of reading height, sturdy and durable.
Existing two embodiment of accompanying drawings.Fig. 1 is a kind of internal structural map of detector, and Fig. 2 is the outline drawing of detector, and Fig. 3 is the internal structural map of the another kind of embodiment of detector.
Marginal data: 1-indicates cover, and 2---the scale label, 3---spring, 4,---the pressure indicating arm, 5---housing, 6---interior push rod, 7---spring base, the 8-clamp nut, 9---ring washer, 10---sealing ring, 11---joint, 12---plunger, 13---anti-extrusion ring, 14---sealing ring.
Embodiment one (with reference to accompanying drawing 1 and accompanying drawing 2), spring 3 is housed in housing 5, spring 3 lower ends withstand on the spring base 7, be with pressure indicating arm 4 in the spring 3, indicating arm 4 lower end screw threads are connected on the interior push rod 6, indicating arm 4 upper ends are associated with indication cover 1, and are enclosed within the first half outside of housing 5, the label 2 of a fixed band scale in housing 5 first halves outside; Load onto plunger 12 in the mesopore with joint 1 again, put anti-extrusion ring 13 and sealing ring 14 on the plunger 12, and compress with nut 8; Then with joint 11 usefulness thread connection on housing 5.
This detector is when work, and indication cover 1 can be read instant operating pressure with indicating arm 4 and 6 one liftings of interior push rod.
Embodiment two (with reference to accompanying drawing 3 and accompanying drawing 2), concrete scheme is basic identical with embodiment one, but pressure indicating arm 4 bottoms be hollow and and ring washer 9 be enclosed within together on the interior push rod 6, at housing 5 tops sealing ring 10 is housed.The characteristics of this pressure detector are, indication cover 1 can rest on the former graduation mark when operating pressure descends, demonstrate the maximum pressure in the work, the staff indicates cover 1 down with hand after reading maximum pressure, indicating arm 4 is contacted with interior push rod 6, and indication cover 1 graduation mark that stops is instant operating pressure.
