Abstract

Disclosed is a warning indicating level instrument, comprising a closed container and an upper and a lower frames used for clamping the closed container. The surface of the closed container is provided with the scales of gradient, and liquid is filled in the closed container. The utility model is characterized in that the closed container is filled with light-tight liquid, the upper and the lower frames are fixed with a luminous tube and a photosensitive tube corresponding to different scales respectively, and a light-sensitive signal is used as the input signal of an alarm circuit. The utility model is especially suitable for travelling cranes. The utility model can send out alarm accurately via euphonious and conspicuous acoustic and optical signals in an oblique way through the proper collocation of the alarm circuit, which is visual and obvious. Besides, the warning indicating level instrument can stop lifting work when the angle of slope goes beyond a given value to guarantee the safe operation of cranes.

Description

Warning indicating level-meter

The utility model relates to the degree of tilt testing tool.More particularly, be a kind of level meter that can tilt to warn with sound, light, electric signal.

Level meter of the prior art, no matter be the tubulose level meter of only indicating horizontal level in one direction, or on comprehensive the discoid level meter of indication horizontal level, all be to divide at airtight internal tank to fill liquid, thereby leave bubble, with the position indication degree of tilt at bubble place.There is following weak point in this level meter: when using it for the plant equipment that needs keep the horizontal operation state, especially when being used for mobile type hoist, in case crane work process middle machine body angle of inclination surpasses safe range, because the serious accident that fuselage topples can not will take place immediately with the operator of tangible signal announcement in level meter.

Also not having at present can be with instrument electric, that sound and optic signal tilts caution.

The purpose of this utility model is to avoid the deficiencies in the prior art part, a kind of mobile type hoist that needs keep the horizontal operation state that is particularly useful for is provided, carry out the fuselage gradient measurement, and can send tangible sound, the light signal of warning immediately at the tilting value of setting, export electric signal simultaneously, so that directly cut off relevant electric power loop, thereby guarantee crane safety work.

The purpose of this utility model is achieved through the following technical solutions.

The utility model is made of upper frame, the underframe of closed container and this container of clamping.Vessel surface has the angle of inclination scale.Internal tank divides filled liquid, to leave bubble.

Of the present utility model being characterised in that:

The liquid that fills in a, the described container is light tight liquid.

B, on upper and lower framework, corresponding to the position of the different scales of vessel surface, fixedly luminotron and photosensitive tube respectively; Described photosensitive tube is connected the warn input end of circuit of respective electrical, sound, light.

The utlity model has following advantage.

The utility model is applicable to any plant equipment, especially mobile type hoist that needs to keep the horizontal operation state.By suitable configuration warning circuit, can tilt to warn with melodious eye-catching sound and optic signal exactly, simple and clear, and can surpass when presetting scope at the angle of inclination, cut off relevant working power immediately, stop lifting work.The utility model is simple in structure, easy to implement, for crane safety work provides assurance.

Number in the figure: 1, upper frame, 2, underframe, 3, container, 4, scale, 5, bubble, 6, luminotron, 7, photosensitive tube, 8, bolt.

By the following examples, in conjunction with the accompanying drawings the utility model is further described.

Embodiment:

In the present embodiment, setting the angle of inclination is normal operating conditions in the time of 0 °～1 °; Be alarm condition in the time of 1 °～2 °.

Referring to Fig. 1, Fig. 2, adopt discoid closed container (3), container (3) surface has the scale (4) at expression angle of inclination, and the scale value on the same circumference is identical.Part fills the light tight liquid of black in the container (3), and leaves bubble (5).Container (3) is by upper frame (1) and underframe (2) clamping, and upper and lower framework gives fastening by bolt (8).On upper frame (1), be on the circumference of 1 ° and 2 ° corresponding to scale, 8 light emitting diodes (6) of evenly arranging respectively corresponding to every light emitting diode (6) position, are gone up fixedly phototriode (7) at underframe (2).

Referring to Fig. 3, wherein XD1 is that blue look, XD3 are for yellow for red, XD2.As shown in the figure, LED 1 and LED2 are parallel with one another, and insert electric power loop by K switch.When K switch is connected, LED1 and LED2 Chang Liang.

8 photosensitive tube BG1 that are arranged on 1 ° of scale value whole circumference are parallel with one another, and are connected the input end of alarm circuit I; 8 photosensitive tube BG2 that are arranged on 2 ° of scale value whole circumference are parallel with one another, and are connected the input end of alarm circuit II.

When the equipment under test angle of inclination in 1 °, bubble (5) is positioned in (3) 1 ° of circumference of disk container, all phototriodes end because of not being subjected to light, relay contact all is in initial position, XD2 is with blue coloured light indication normal operating conditions.

When the equipment under test angle of inclination reaches 1 °, the phototriode BG1 of the mobile position of bubble (5) sees through light signal thereby the conducting that bubble receives LED 1, make relay J 1 work by triode BG3, therefore XD3 and L2 get, send yellow light and the bass signal of warning respectively, with prompting operation person.

When the equipment under test angle of inclination reaches 2 °, the phototriode BG2 of the mobile position of bubble (5) sees through light signal thereby the conducting that bubble receives LED 2, and make relay J 2 work by triode BG4, therefore XD1 and L1 get, send red light and the high pitch signal of warning respectively, and act on related circuit by relay P simultaneously, so that equipment quits work, avoid accident to take place.

Claims (2)

1, a kind of level meter of warning is made of upper frame, the underframe of closed container and this container of clamping; Described vessel surface has the angle of inclination scale, and part fills liquid in it; It is characterized in that:

The liquid that fills in a, the described container is light tight liquid;

B, on upper and lower framework, corresponding to the position of the different scales of vessel surface, fixedly luminotron and photosensitive tube respectively; Described photosensitive tube is connected the warn input end of circuit of respective electrical, sound, light.

2, level meter according to claim 1 is characterized in that: described container is discoid, corresponding to different inclination scales on the disk, and evenly arrange on its whole circumference some luminotrons and corresponding photosensitive tube, described some photosensitive tubes are parallel with one another.
