Abstract
The utility model relates to a pressure measurer, which is used for the value of the working pressure inside a single body hydraulic support post used under a well of a coal mine. The utility model is composed of two parts of a meter head and a pressure measuring device, wherein, the meter head is composed of a shaft, a meter disk, and an indicating needle; the pressure measuring device comprises an outer shell, a piston, a rack, a spring, a supporting seat, a pinion, a supporting seat, a transmission shaft, a sealed ring, etc. The upper end of the piston is connected with the rack. When the pressure measurer is installed on a movable post body, the piston upwards moves under the action of the oil pressure of a hydraulic cavity to drive the rack to move. The rack and the pinion are engaged to make the pinion rotate. The transmission shaft rotates under the driving of the pinion, the shaft of the meter head, which is connected with the transmission shaft rotates to drive the indicating needle to rotate. Thus, the valve of the oil pressure can be displayed.
Description
The utility model relates to a kind of hydraulic pressure checkout gear, the hydraulic prop pressure detector that is particularly useful for using under the coal mine.
The pressure tester kind of the hydraulic prop that uses under coal mine at present is a lot, and as the hydraulic prop pressure detecting instrument, its patent No. is 89217105.7 and the hydraulic prop pressure indicator, and the patent No. is: 89211331.6; The former shortcoming is a complex structure, and the cost height uses inconvenient.The latter is also because its complex structure, and measures inaccurately, and owing to its structural reason, fragile indicator when removing post again because of it has bored individual hole on post jamb, reduces the life-span of pillar widely, and using aborning all has certain limitation.
The purpose of this utility model is to have designed a kind of new manometer in order to overcome above-mentioned weak point, be characterized in making manometer to be directly installed in the post alive of support, show in the post side of living by little axle and pointer, can observe the fluid pressure in the hydraulic support easily intuitively.It is made up of gauge outfit and pressure tester two parts; Gauge outfit comprises little axle, dial plate and pointer, and pressure tester comprises top cover, pinion, tooth bar, spring, bearing, power transmission shaft, shell, piston and sealing ring etc.Manometer is installed on the hydraulic support cylinder alive, it is communicated with high-voltage oil cavity, oil pressure promotes piston compression spring and moves up and down, drive the tooth bar motion that is connected with its top, pinion is rotated under the drive of tooth bar, by gear drive little axle is rotated and drive the pointer rotation that is contained on its termination, and pass through the size of the scale demonstration pressure of dial plate, so just can measure the fluid pressure of system intuitively.This manometer is simple in structure, makes easily, and is easy to operate, reliable in action, loading and unloading easily.
