Description

Tester for level degree of wall surface

The utility model relates to and detects the plaster instrument field of degree of plainness for wall surface of new construction.

It is more original measuring at present the plaster instrument of degree of plainness for wall surface of new construction, and generally by wooden ruler, its length is as requested 2 meters, and standard claims that it is 2 meters rulers, also has one in addition clearance gauge.Carry out with 3 people during detection, wherein a people comes to ruler and is examined on the metope, and the space between another human range estimation ruler and the metope is filled in clearance gauge in the slit again, and the degree of depth that clearance gauge inserts is big more, shows that then its flatness is poor more.This measuring method shortcoming is a lot.As because metope is very high, and ruler also has only two meters long, hold the clearance gauge people and then reach so highly, generally estimate number by the inspection group more than three people, this detection data are unscientific, and very mistake is arranged.

The purpose of this utility model is: provide a kind of by the degree of plainness for wall surface measuring instrument of forming as main frame, electron device and the mechanical transmission component of ruler, this instrument can accurately be measured two meters scopes rapidly with interior degree of plainness for wall surface, and the resolution of its degree of accuracy reaches 0.01 millimeter.

The purpose of this utility model reaches like this: be provided with 2 meters long, cross section and be the straight main frame that 80 * 50 millimeters, both sides have fluting; Be provided with the abdomen car of belt sensor in main frame, the sensing wheel of sensor notch behind the main frame back side stretches out with measured metope and contacts, and LCD notch before the main frame stretches out; In main frame, also be provided with the mechanical driving device of abdomen car.With the electricity is machine power, affects the sensing wheel of sensor to move along metope, and sensor is delivered to the smooth situation at survey position on the digital screen of LCD, can obtain the precise figures of surveying, thereby the purpose of this utility model has just reached fully.

Below in conjunction with accompanying drawing this measuring instrument is elaborated.

Accompanying drawing 1 is that the synoptic diagram of this measuring instrument: 1a is a front view; 1b is a side view; 1c is the A-A sectional view of main frame.

Accompanying drawing 2 is abdomen car synoptic diagram.

In order to improve the backward situation of degree of plainness for wall surface survey instrument, the utility model adopts the robotization detector of forming with parts such as electronics, machineries.

The used sensor 3 of this measuring instrument is to adopt Beijing Measuring and Cutting Tools Factory to produce: " the stainless steel electronic digit shows slide calliper rule " and capacitive grid type digital display measurer LCD external display device.This device is the SYLVAC amount system that this factory introduces from Switzerland, and the resolution of this system is 0.01 millimeter.This measuring instrument is changed this device part, and LCDs is drawn and enlarged from transducing part.

From accompanying drawing 1 as seen, the main frame of this measuring instrument is that 2 meters long, cross section are 80 * 50 millimeters, and have the straight member of fluting.So with 2 meters long is to come according to the technical stipulation of checking degree of plainness for wall surface, flatness is the concavo-convex situation of checking in two meters scopes of metope.Certainly the rear side of this measuring instrument main frame 1 must be straight.So the main frame 1 of this instrument can be gone up the abdomen car 2 that lower edge fluting walking has sensor in order to install therein exactly with 80 * 50 millimeters in cross section.For the purpose of narration, after the side that sensing wheel is extended out is decided to be, and before the side that LCDs is stretched out is decided to be.From accompanying drawing 1a as seen at the main frame rear up and down two ends have rubber suspension column 11 contact metopes so that the abdomen car slides along main frame inside.Have back fluting 13 from visible this instrument rear of 1b, sensor 31 stretches out from this fluting, and LCDs 5 is slotted in the past and 12 stretched out.From the A-A sectional view of the visible accompanying drawing 1a of accompanying drawing 1c, the height before and after this main frame is 80 millimeters, and width is 50 millimeters, and length is 2000 millimeters.

The mechanical driving device 4 of the abdomen car 2 of belt sensor by micromachine and variator 41, the hand-held flexible cord of power-supply battery is installed, and two-way switch 42, pulley 43 and lifting rope 44 are formed anyway.Micromotor and variator 41 are located at the lower end in the main frame 1, are provided with pulley 43 in the main frame upper end, and it bears the lifting rope 44 between abdomen car 2 and the variator 41, by lifting rope 44 and pulley 43, the abdomen car can be moved in main frame along fluting.

Accompanying drawing 2 is the abdomen facing figure that are installed in the main frame.From accompanying drawing 2 as seen, abdomen car 2 has 8 plastics rubber tires 29, on main frame 1 front and back side, move respectively, sensor 3 and LCDs 5 are installed on the abdomen car 2 to be moved with car, the sensing wheel of sensor 3 with main frame 1 back side after fluting 13 stretch out, be provided with limiting plate 21 in the place ahead of sensing wheel 31, it is controlling the length of stretching out and regaining of sensor, be provided with fixing preceding bearing shell 22 in abdomen car front part sides, hold and cut front axle 23, and be provided with revocable square toes cover tile 24 in both sides, abdomen car 2 rear portion, two sides are provided with rear axle spring 27 between sensor 25 backs and rear axle 26, so that it is support rear axle little mobile, without hindrance when guaranteeing operation.In addition, be provided with front spring 28 between sensor 3 front portions and abdomen vehicle frame, front spring 28 can keep the pressure of sensing wheel to metope.

During use, the appropriate location of the metope of selecting to plaster is detected metopes with the upper and lower suspension column 11 of this measuring instrument near these, starts motor the abdomen car is moved for 2 times, drives sensor 3 work, and when sensing wheel 31 detected convex surface, sensing wheel shrank; When sensing wheel 31 is visited concave surface, because the pressure effect of sensor 3 front spring 28 is stretched out sensor 3, when LCDs 5 is received convex-concave that sensor surveys and is spent, promptly be converted to liquid crystal digital, on screen, clearly show, can record the degree of plainness for wall surface of the metope of plastering.When abdomen car 2 rose to the top, power supply was cut off, shuts down, and started the reverser button then, and the abdomen car is descended, and can record identical result.

The utility model degree of plainness for wall surface measuring instrument is formed the detection means of robotization with electronics, mechanical part, the resolution of precision can reach 0.01 millimeter (the tame standard of being engaged in is radix with 1.0mm), improve the accuracy that construction quality is inspected for acceptance greatly, for building industry contributes in quality check and construction.
