Abstract

The utility model discloses a guide track checkout device, in particular to a laser directing instrument used on lateral working surface of a T type guide track so as to inspect the direction of the working surface of a T type guide track of an orthograde elevator. The utility model is characterized in that: a shell body[2] is provided with a laser[6] and a chucking appliance[1]; wherein, a testing reference surface is arranged on the chucking appliance[1] and the centerlines of the beam of the laser are coplanar with the testing reference surface. Compared with the prior art, the utility model has the advantages of high precision, convenient use, simple structure and easy carry; moreover, the utility model provides a convenient and reliable checkout gear to the installation of the guide way of vertical elevator.

Description

T type rail-sides workplace laser orientation instrument

Technical field:

The utility model relates to a kind of guide rail pick-up unit, and particularly a kind of T type rail-sides workplace laser orientation instrument is mainly used in the orientation that detects the formula elevator T type working face of guide rail that walks upright.

Background technology:

In vertical type walking elevator, generally use the track of T type guide rail at present as its walking.In production and mounting guide rail process, its linearity is more easy to control, but the torsional deformation of its workplace and the azimuthal control ratio when installing be difficulty, along with the quickening of the traction speed of elevator, requires also more and more stricter to the control at the installation position angle of rail-sides workplace.When installing, cage guide mostly use " looking for track forces " to measure at present, as shown in Figure 2: lean against with " looking for track forces " 16 on the workplace of guide rail 15 of a side, measure the deviation h that opposite side occurs, because the width n of rail-sides workplace is less, generally in the 30-50 millimeter, the slit h that produces with narrow like this width shows that it is irrational that guide rail is surveyed the azimuthal method of workplace, deviation as 1 ° of T type guide rail installation position angle appearance, when face width n is 33 millimeters, with the gap height h of looking for track forces to detect is 33 * sin1 °=0.58 millimeter, and during practical operation, disturb the size of differentiating the slit just more difficult because range estimation is subjected to guide rail.

Summary of the invention:

The purpose of this utility model provides a kind of simple in structure, T type rail-sides workplace laser orientation instrument that resolving accuracy is high, easy to use, overcomes the deficiencies in the prior art.

Technical solution of the present utility model is: a kind of T type rail-sides workplace laser orientation instrument, it is characterized in that: be fixed with laser instrument 6 and jig 1 on the housing 2, jig 1 is provided with the test benchmark face, the beam center line of laser instrument 6 and described test benchmark face coplane.

Described housing 2 is provided with power supply 3 and joins with laser instrument.

The light hole place that is positioned at laser instrument 6 on the described housing 2 is provided with attenuator 5.

Described test benchmark face is made of the upper surface of the expansion screw 8 on upper surface that is fixed on the locating pin 7 on the jig 1 and the jig 1.

Described laser instrument 6 is fixed on the v block fixed block 4, and v block fixed block 4 is fixedly connected with housing 2.

The utility model compared with prior art has precision height, advantage easy to use, and is simple in structure, portable, for the installation of vertical type walking cage guide provides convenient and reliable pick-up unit.

Fig. 2 uses in the prior art to look for track forces testing synoptic diagram;

Fig. 3 is the correct synoptic diagram of guide rail installation position;

Fig. 4, Fig. 5 are the incorrect synoptic diagram of guide rail installation position;

Fig. 6 is to use this device to detect guide rail installation position work synoptic diagram.

Embodiment:

As shown in Figure 1: 2 is housing, can adopt sheet metal to make, be connected with jig 1 in a side edge bolt of housing 2, the plate face screwing of housing 2 is fixed with v block 4, laser instrument 6 is fixed on the v block 4, and its fixing means is with screw and pressing plate laser instrument 6 to be pressed on the v block 4.Tighten at the medial surface of jig 1 and to be combined with locating pin 7, upper and lowerly be provided with two respectively.Expansion screw 8 and jig 1 thread connection.The beam center line of described laser instrument 6 and locating pin 7 upper surface coplanes.On the light hole place of laser instrument 6 housing 2, be fixed with an attenuator 5, be controlled in the safe range of national regulation to guarantee the laser energy that penetrates.

Its use is as follows: shown in Fig. 1,6: with jig 1 this device is fixed on the T type guide rail 9, the end face of locating pin 7 leans on the side workplace of guide rail 9, make laser beam and rail-sides workplace coplane with expansion screw 8 adjustment, adjusting finishes seals expansion screw 8 admittedly.Above-mentioned adjustment work is very simple, because two side workplaces of guide rail are parallel, positive and negative each dress once, if laser beam and side workplace coplane, then positive and negatively be loaded on the two bundle laser beam that the side workplace produces respectively for twice and should equating perpendicular to the projector distance in the plane of rail length direction, and equal the thickness of guide rail,, then should adjust expansion screw 8 till equating if unequal.

Because the guide rail of elevator is to settle in pairs, so whether their side workplace also be comparatively speaking correctly in the orientation in space, and to install be correct to two guide rails among Fig. 3, and the installation of Fig. 4,5 two guide rails is wrong.Shown in Figure 6 is to measure by the duty of dress working face of guide rail position of orientation with this device, the numerical value A that laser beam shows at another root rail-sides workplace place, be exactly that tested guide rail is answered adjustment amount on the position angle, promptly adjust guide supporting seat cushion piece, making the guide rail position angle reach the A value at last is zero.Use the same method, another root guide rail is measured, adjust its lip block, last pair of guide rails reaches state shown in Figure 3.
