Technical field
The utility model relates to dip measuring device field, especially a kind of hydraulic support column dip measuring device.
Background technique
Hydraulic support is a kind of hydraulic power for carrying out supporting and management to top plate using fluid pressure generation support force
Device, hydraulic support is essential equipment in comprehensive mechanical coal mining, and column is the main forced section of hydraulic support
Part.It is measured by the pressure of the emulsion to hydraulic support, so that it is determined that hydraulic support stress, and to coal working face
Mine pressure is analyzed, so that controlroof moves, or realizes the type selecting to hydraulic support.But make in hydraulic support
With in the process, with the lifting of support height and the variation of seam inclination, stem height and inclination angle change therewith, use column
The pressure instead support force of internal emulsification liquid simultaneously carries out that Mine pressure analysis precision is relatively low, need the inclination angle of column to measure to
It accurately obtains support force situation or mine pressure is analyzed.
Utility model content
To solve the measurement of hydraulic support column inclination angle, to accurately determine that the technology of support force analysis mine pressure is asked
Topic, the utility model provide a kind of hydraulic support column dip measuring device, and specific technical solution is:
A kind of hydraulic support column dip measuring device, including rack body, column, weight, shaft, pointer, dial
And protective shell；For the column in the middle part of rack body, weight, shaft, pointer and dial constitute tilt angle monitoring device；It is described to incline
The specific structure of angle monitoring device is that weight is at right angles fixedly connected with pointer, and shaft is in the junction of weight and pointer, scale
Disk is arranged in pointer end；The protective shell is arranged on tilt angle monitoring device.
Further, described shaft one end is fixed on the side of column, and shaft passes through the logical of weight and pointer junction
Hole, weight and pointer smooth rotation around the shaft.
Further, the shaft surface is provided with lubricant coating.
Further, the weight is in cone, and center of gravity is on the axis of circular cone.
Further, transparent glass window is provided on the protective shell.
Further, indicator light is provided at each integer scale of the dial, pointer hides by integer scale
Keep off indicator light.
The beneficial effects of the utility model include: that (1) is provided with tilt angle monitoring device on column, can real-time measurement it is vertical
Column inclination angle, so as to further accurate analysis support force situation；(2) protection is provided on tilt angle monitoring device
Shell can make the environment more than tilt angle monitoring device adaptation underground coal dust, and tilt angle monitoring device can be prevented by avalanche coal mine
It hits and damages；(3) shaft is smooth and can guarantee the sensitivity of tilt angle monitoring device equipped with lubricant coating；(4) on protective shell
It is provided with transparent glass window, and indicator light is set on dial, the reading of underground coal mine environment can be facilitated.This is practical
It is novel also to have structure simple, it is easy for installation, the advantages of strong applicability.

Specific embodiment
In conjunction with shown in Fig. 1 to Fig. 3, a kind of hydraulic support column dip measuring device provided by the utility model is done into one
Step illustrates.
A kind of hydraulic support column dip measuring device specifically includes rack body 1, column 2, weight 31, shaft 33, refers to
Needle 32, dial 34 and protective shell 4.Column 2 was arranged at the middle part of rack body 1, weight 31, shaft 33, pointer 32 and quarter
Scale 34 forms tilt angle monitoring device 3, and tilt angle monitoring device 3 is arranged on the side of column 2.Pass through tilt angle monitoring device 3
The inclination angle for capableing of real-time measurement column 2 is set, so as to further accurate analysis support force situation.Inclination angle monitoring dress
The specific structure set is that weight 31 is at right angles fixedly connected with pointer 32, and weight 31 is in cone, axis of the center of gravity in circular cone
On；Shaft 33 is fixed on the side of column 2 in the junction of weight 31 and pointer 32,33 one end of shaft, and shaft passes through weight
31 and 32 junction of pointer through-hole, weight 31 and pointer 32 smooth rotation around the shaft, or shaft surface is provided with lubrication
Coating.Dial 34 is arranged in 32 end of pointer, Preferable scheme is that being provided with instruction at each integer scale of dial
Lamp 35, pointer 32 block indicator light by integer scale.Protective shell 4 is arranged on tilt angle monitoring device, inclination angle can be made to monitor
Device adapts to the environment more than the coal dust of underground, and can prevent tilt angle monitoring device from being damaged, protective shell 4 by the shock of avalanche coal mine
On be provided with transparent glass window 41, the reading of underground coal mine environment can be facilitated.
As shown in figure 3, the structure of the utility model hydraulic support column dip measuring device is further illustrated, in hydraulic vertical
The dip measuring device initial makeup location installed on column is that weight is equally vertically-mounted when column is vertical, and pointer is horizontal at this time,
The numerical value that pointer indicates on dial be 0, as column inclined scale disk is tilted with column, weight still keep vertically, because
The numerical value that this pointer indicates on dial is the inclination angle of column.The actual loading of hydraulic support is that column internal emulsification is hydraulic at this time
Power is corrected support force and mine pressure observation value multiplied by the cosine value at column inclination angle.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.
