Description

Roller type photoelectricity stroke sensor

Technical field

The utility model relates to a kind of photoelectricity stroke sensor, particularly a kind of roller type photoelectricity stroke sensor.

Background technology

In the modern building fabric installation work, heavy construction structural entity length is applied apart from non-rectilinear slippage field engineering.Growing apart from situations such as the stroke in the non-rectilinear sliding construction, attitude, distortion in order to control the heavy construction structure, guarantee the safety of structure and installation in position accurately, general now utilization photoelectricity stroke sensor is implemented monitoring to the displacement situation of each creep setpoint of heavy construction structure when the construction.Than higher, for example but the factors such as vibration of working-yard can influence its operate as normal to existing photoelectricity stroke sensor, and the purchase cost of photoelectricity stroke sensor is also higher on the market to the requirement of working environment.The working-yard needs to adapt to the building ground environment, uses more convenient, lower cost, and can satisfy long photoelectricity stroke sensor apart from non-rectilinear sliding construction observing and controlling accuracy requirement.

Summary of the invention

The purpose of this utility model is to solve the existing problem of existing photoelectricity stroke sensor, provide a kind of simple in structure, make simple and easy, easy to use, with low cost and can satisfy building element long apart from the non-rectilinear sliding construction in the photoelectricity stroke sensor of displacement detecting and controlling accuracy requirement of each creep setpoint.The utility model design roller type photoelectricity stroke sensor, comprise base plate, key seat and pin; rocking arm; rotating shaft; bearing; roller; rubber ring; optical fiber photoelectric switch; extension spring etc.; it is characterized in that: at the fixing key seat of an end of base plate; an end of rocking arm is connected on the key seat by pin; the other end of rocking arm is installed bearing; rotating shaft and roller; the outer ring of the roller rubber ring of wrapping; the middle part of rocking arm connects an end of extension spring; the other end of extension spring connects base plate; be equipped with signal emission receiver hole at the rocking arm middle part, optical fiber photoelectric switch be fixed on the rocking arm and signal emission receiver hole that the transmitting terminal and the receiving end of its optical fiber is installed in rocking arm respectively in; Rotation roller, aim on the wheel face signal emission on the rocking arm on the circumferential position of receiver hole, be equipped with the aperture of equidistance continuously, the spacing distance of aperture is determined by accuracy requirement.The utility model has the advantages that simple in structure, make simple and easy, easy to use, with low cost and can satisfy building element long apart from the non-rectilinear sliding construction in the accuracy requirement of displacement detecting and controlling of each creep setpoint.

Description of drawings

Fig. 1 .2 is a structural representation of the present utility model.

Below in conjunction with drawings and Examples the utility model is elaborated.

Specific implementation method

Comprise base plate 1, key seat and pin 2, rocking arm (two of same sizes) 3, rotating shaft 4, bearing 5, roller 6, rubber ring 11, optical fiber photoelectric switch 7, extension spring 8 etc. among the figure.At the fixing key seat 2 of an end of base plate 1, key seat 2 is connected by pin with an end of two rocking arms 3, the other end of two rocking arms 3 is respectively installed a bearing 5, two bearing 5 clamping rotating shafts 4, fixed idler whell 6 in the rotating shaft 4, the outer ring of roller 6 rubber ring 11 of wrapping; the middle part of rocking arm 3 connects an end of extension spring 8; other end of extension spring 8 connects base plate 1; respectively be equipped with at two rocking arm 3 middle parts a signal emission receiver hole 9 can contrast, optical fiber photoelectric switch 7 be fixed on the rocking arm 3 and signal emission that the transmitting terminal and the receiving end of its optical fiber is installed in two rocking arms 3 respectively in the receiver hole 9; Be processed into the wheel face of roller 6 with smooth epoxy glass fiber laminate, rotation roller, aim on the wheel face signal emission on the rocking arm 3 on the circumferential position of receiver hole 9, the central angle of 10, two the adjacent apertures 10 that are with holes continuously is 5 degree.

Base plate 1 of the present utility model is fixed on by each creep setpoint of building structure, make roller 6 be close to slide rail, in the construction when building structure on slide rail during slippage, roller 6 can roll on the slide rail face, each aperture 10 on the wheel face can skim over successively signal emission receiver hole 9, optical fiber photoelectric switch 7 just receives the pulse train signal, and the pulse signal of each measuring control point is given control computer, can learn the stroke of each monitoring site of building structure and the synchronous situation of displacement by analysis.Use this roller type photoelectric displacement sensor, can not only satisfy the precision of the stroke of building element in sliding construction and each observing and controlling position slippage sync status, and the construction site condition of work there is not specific (special) requirements, it is simple in structure, making is simple and easy, easy to use, with low cost, can satisfy the monitoring needs of building element length apart from the non-rectilinear sliding construction.
