Description

Hydraulic support cap ball-and-socket size detection chi
Technical field
The utility model relates to a kind of measurement mechanism, for the measurement of hydraulic support physical construction class, and a kind of hydraulic support cap ball-and-socket size detection chi specifically.
Background technology
Hydraulic support is the important support apparatus of colliery fully-mechanized mining workplace, and cap is wherein the body junction member of support, is a vital part on back timber, and cap ball-and-socket and column column cap join, and are directly carrying the pressure of mine roof.
Cap adopts cast form conventionally, and material is foundry goods, and its common structure as shown in Figure 1, has corresponding position dimension requirement with the ball-and-socket that column cap is installed at the bottom of the otic placode half-arc groove of column cap pin is installed in project organization.The upper-lower position size of this half slot and ball-and-socket is a critical size in design, is also one and is difficult to the bulk of measuring simultaneously.If this size can not meet drawing requirement, directly cause column column cap not connect top, if column cap does not connect top, cause column cap pin stressed, bearing pin is crooked, damage, and serious cannot dismantle, directly affect hydraulic support in the normal use of down-hole, thereby the measurement of this bulk seems particularly important.
In production testing over the years, to this bulk, adopt self-control model to detect always, in addition, other effectively testing tool never.And self-control sample making difficulty likely produces and scraps in cutting process processed, more again make, and model versatility is low, every batch of workpiece need be made a model, causes this detection method comparatively loaded down with trivial details.
Except the upper surface of cap shown in Fig. 1 is plane common structure, also having a kind of structure is that cap upper surface is inclined-plane, and secondly there are open type and band wall board type in otic placode both sides.For this reason, we are badly in need of designing a kind of good cap ball-and-socket size detection chi of versatility that is applicable to all structures.
Summary of the invention
The purpose of this utility model is in order to solve above-mentioned problems of the prior art, and a kind of hydraulic support cap ball-and-socket size detection chi is provided, and is a kind of effective, simple and practical measurement mechanism.
The utility model is achieved by the following technical solution:
A hydraulic support cap ball-and-socket size detection chi, comprises chi beam, and the centre position before chi beam is provided with a main scale by fixture block, and the end positions before chi beam is respectively provided with a secondary chi by cross key, fixture block is rotatably connected on centre position before chi beam, and (that is: the fixture block back side is fixed with bearing pin, bearing pin is plugged on chi beam, between fixture block and chi beam, can relatively rotate), fixture block is provided with draw-in groove, main scale slip holding is (that is: main scale can arbitrarily slide in fixture block) in draw-in groove, on fixture block, be also provided with trip bolt for fastening main scale (that is: the trip bolt that has been threaded on fixture block, the ailhead of trip bolt can extend in draw-in groove, can make the main scale relative with fixture block fixing by twisting trip bolt), on chi beam, offer along its length two with the first symmetrical chute of chi beam mid point, on secondary chi, offer along its length the second chute, cross key comprises two rectangular parallelepiped pieces, two rectangular parallelepiped pieces are cruciform vertically to be fixed, in first chute of one of them rectangular parallelepiped piece slip holding on chi beam, in second chute of another rectangular parallelepiped piece slip holding on secondary chi, the thickness sum of two rectangular parallelepiped pieces is less than the thickness sum (like this, cross key fitted bolt guarantee chi beam and secondary chi can fully compress) of chi beam and secondary chi, in cross key, offer tapped through hole, two apertures of tapped through hole lay respectively at the back side of the rectangular parallelepiped piece of holding in the first chute and the rectangular parallelepiped piece of holding in the second chute before, in tapped through hole, be inserted with bolt, bolt head is positioned at the back side of the first chute rectangular parallelepiped piece, screw head be positioned at the second chute rectangular parallelepiped piece before, wing nut has been threaded on screw head, between the back side of the interior rectangular parallelepiped piece of bolt head and the first chute, between before the interior rectangular parallelepiped piece of wing nut and the second chute, be all provided with pad (bolt, pad and wing nut coordinate and chi beam and secondary chi can be fixed), beam section over against the first chute is all provided with scale on main scale, on secondary chi and on chi beam, on the rectangular parallelepiped piece of holding in the first chute, be fixed with the pointer that is used to indicate secondary chi high scale.
While using the utility model measurement device, as shown in Figure 3, two secondary chis are slided along the first chute on chi beam, adjust to cap two otic placode spacing, again two secondary chis are adjusted to the ball-and-socket centre of sphere to the size (scale that guarantees two secondary chi indications is consistent) of otic placode circular arc R bottom along the second chute on it, fastening WING NUTS, two secondary chis are put into otic placode circular arc, with main scale, directly measure the cap ball-and-socket centre of sphere to this bulk of ball bottom, and rotation main scale can measure the upper any point of SR, can detect the correctness that ball-and-socket is spherical simultaneously.The utility model device can detect the upper-lower position size of the ball-and-socket centre of sphere easily, thereby determines arc groove and ball-and-socket upper-lower position size correctness.
Further, the bottom of secondary chi is designed arc-shaped appearance, has guaranteed the good contact of secondary chi and cap otic placode circular arc.
The beneficial effect of the utility model device is:
1) the utility model pick-up unit manufactures and designs, solved the detection difficult problem in support cap space, not only met the related request of support cap dimension control, and effectively control product workmanship, problem is stopped at first working procedure, do not brought into next procedure and affect hydraulic support in the normal use of down-hole;
2) versatility is well the most significant effect of the utility model pick-up unit, be applicable to the size detection of current all structures and specification cap, compare the unicity that model is measured, the utility model pick-up unit is convenient and swift, not only can measure accurately institute's dipping cun, and easy to operate, detection efficiency is high;
3) the utility model pick-up unit can be made by light material, very light, is convenient to move around in check work.
