Further, the top of described measuring tube is connected with installing ring, the bottom of described measuring tube offers two connecting holes, and described two connecting holes are relatively arranged on the sidewall of described measuring tube, is also inserted with and described connecting hole and the suitable connecting pin of installing ring in described two connecting holes.
Further, described measuring tube is polyvinyl chloride pipe.
Further, the reflecting strips that has been sticked on the outer wall of described measuring tube.
Further, described indication piece is indicating ring, and described sounding rod is set in described indicating ring.
It is not only simple in structure for measuring the measurement mechanism of back production height of fully-mechanized mining working that the utility model provides, easy to install and use, and can measure exactly the mining height of fully-mechanized mining working, thus instruct coalcutter driver coal cutting, reduce top retained coal body, improve resource recovery.
Brief description of the drawings
Fig. 1 is that the utility model is a kind of preferably for measuring the schematic diagram of measurement mechanism of back production height of fully-mechanized mining working.
Embodiment
Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is described in detail.Wherein identical parts represent with identical Reference numeral.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric center.
As shown in Figure 1, the utility model provide for measuring the measurement mechanism of back production height of fully-mechanized mining working, comprise the sounding rod 1 with Measurement scales and the indication piece 2 that is used to indicate described Measurement scales, described sounding rod 1 is arranged on the below of the back timber of hydraulic support vertically by magnetic hanger 3, described indication piece 2 is fixed on the column of hydraulic support by support bar.
As a kind of preferred version of the present utility model, described magnetic hanger 3 comprises magnetic body and is arranged on the butt hook on described magnetic body, described magnetic body comprises upper surface and lower surface, more preferably, described magnetic body is round table-like, in described round platform, larger end face is as the upper surface of magnetic body, less end face is as the lower surface of magnetic body, described upper surface is connected with the back timber magnetic of hydraulic support, larger upper surface contributes to the magnetic strength of joint of the back timber that improves magnetic body and hydraulic support, improve the connective stability of this device, described butt hook is arranged on described lower surface.The magnetic body of the present embodiment is preferably made up of magnet, and operating personnel only need the upper surface of magnetic hanger 3 to be just directly adsorbed on the back timber of hydraulic support can complete assembling, has effectively simplified installation steps.
As a kind of preferred version of the present utility model, described sounding rod 1 comprises many end to end measuring tubes, assembly crewman can highly increase and decrease according to the back production of actual mine the quantity of described measuring tube, thereby makes the length of sounding rod 1 can meet the mine of different mining heights.
For the ease of assembly crewman's assembly working, the present embodiment be preferably connected with installing ring on the top of described measuring tube, and offer two connecting holes in the bottom of described measuring tube, described two connecting holes are relatively arranged on the sidewall of described measuring tube, are also inserted with and described connecting hole and the suitable connecting pin of installing ring in described two connecting holes.
When assembling, described measuring tube is end to end successively, and two connecting holes of measuring tube bottom and the installing ring of next root measuring tube are oppositely arranged, then described connecting pin is passed to described two connecting holes and installing ring, thereby realize the connection of many measuring tubes, when dismounting, only need extract described connecting pin can disconnect the connection between described measuring tube.Many measuring tubes of the present embodiment employing are assembled sounding rod and have not only been increased measurement range, have also improved the dirigibility of measurement mechanism, have facilitated artificial dismounting and transport.
As a kind of preferred version of the present utility model, described indication piece 2 is indicating ring, and described sounding rod 1 is set in described indicating ring, can prevent that sounding rod 1 from shaking, and improves the stability of this device.When use, described indicating ring is fixed on the column of hydraulic support, thereby keep upper and lower displacement constant, described sounding rod 1 moves up and down along with the activity of the back timber of hydraulic support produces, thereby the relative position of indicating ring and sounding rod 1 is changed, make indicating ring can indicate its corresponding Measurement scales on described sounding rod 1.Certainly, the indication piece of above-mentioned annular is only a kind of preferred version of the present embodiment, and the utility model can also adopt other indicating structure known in those skilled in the art, for example pointer shape indication piece.
