Abstract
The utility model relates to a folding ruler type photoelectric stroke sensor which comprises a square stainless steel pipe and is characterized in that a support is arranged at the top of the stainless steel pipe and provided with a photoelectric signal transmitter and a photoelectric signal receiver opposite to the photoelectric signal transmitter, through holes are arranged on a stainless steel ruler at every 2mm interval, the through holes on the stainless steel ruler, penetrating through the support, are positioned in the square stainless steel pipe, a limit collision block is arranged at the tail of the stainless steel ruler and is in sliding fit with the inner wall of the square stainless steel pipe, and fork entry sheets are arranged at the top of the stainless steel ruler positioned outside a support hole. The folding ruler type photoelectric stroke sensor has the advantages that the stainless steel ruler increases the rigidity so as to avoid the twisting and bending, a fully-stretching minitype stroke switch and a fully-retracting minitype stroke switch are arranged at the head and the tail of the square stainless steel pipe and used for fully-stretching and fully-retracting signal output of the piston rod of an oil cylinder, the stainless steel ruler and the piston rod of the oil cylinder are movably connected between the fork entry sheets by adopting disc plates so as to avoid twisting of the stainless steel ruler when the piston rod of the oil cylinder rotates.
Description
Technical field
The utility model relates to a kind of stroke sensor, is used to detect short oil cylinder running length, particularly a kind of flanging ruler type photoelectricity stroke sensor.
Background technique
Whole building moves to promote and is applied in construction industry at present, move and need also that in the installation process of some large-scale steel structure buildings segmental structure is carried out integral body, for each traction of making integrated member or the displacement that promotes the force keep synchronously, available model utility ZL2004200211048.2 " photoelectricity stroke sensor " is as control unit.But this patent " photoelectricity stroke sensor " employing as critical piece, is limited to the rigidity of steel tape self from the rolling steel tape, produces distortion and crooked in actual use sometimes, causes measurement error.Summary of the invention
The purpose of this utility model is to solve the existing problem of stroke sensor in the prior art, provides a kind of novel capabilities expansion simple in structure the photoelectricity stroke sensor that can satisfy building requirements with low cost.The utility model design flanging ruler type photoelectricity stroke sensor, comprise square Stainless Steel Tube, it is characterized in that: one bearing is arranged on the top of Stainless Steel Tube, photosignal transmitter and relative photoelectric signal receiver are installed on bearing, one Stainless Steel Rule is arranged, every 2 millimeters a through hole is arranged on the Stainless Steel Rule, the through hole that penetrates on the Stainless Steel Rule on the bearing is positioned at square Stainless Steel Tube, tail dress at Stainless Steel Rule is equipped with spacing collision block, spacing collision block and square stainless steel inside pipe wall are slidingly matched, and on the Stainless Steel Rule top that is positioned at the bearing hole outside prong sheet are installed.It is characterized in that: be equipped with at the preceding top of square stainless steel inside pipe wall and stretch position limit switch entirely, full reduced position limit switch is installed at the back top of square stainless steel inside pipe wall.The utility model has the advantages that 1.L type flanging ruler has increased the rigidity of chi, can avoid producing distortion and crooked.2. square Stainless Steel Tube head and afterbody are equipped with micro limit switch, stretch full reduced signal output entirely as the oil cylinder piston bar.3.L type flanging ruler adopts circular disc can actively to connect between the prong sheet with being connected of oil cylinder piston bar, makes L type ruler produce distortion when avoiding the rotation of oil cylinder piston bar.
Description of drawings
Accompanying drawing is a section of structure of the present utility model.
1 Stainless Steel Rule, 2 prong sheets, 3 bearings, 4 photosignal transmitters, 5 photoelectric signal receivers, 6 square Stainless Steel Tubes, 7 stretch position limit switch entirely, 8 full reduced position limit switches, 9 spacing collision blocks, 10 circular discs, 11 Stainless Steel Rule through holes.
Embodiment
It is characterized in that among the figure: one bearing is arranged on the top of Stainless Steel Tube, photosignal transmitter and relative photoelectric signal receiver are installed on bearing, one Stainless Steel Rule is arranged, every 2 millimeters a through hole is arranged on the Stainless Steel Rule, the through hole that penetrates on the Stainless Steel Rule on the bearing is positioned at square Stainless Steel Tube, tail dress at Stainless Steel Rule is equipped with spacing collision block, spacing collision block and square stainless steel inside pipe wall are slidingly matched, and on the Stainless Steel Rule top that is positioned at the bearing hole outside prong sheet are installed.It is characterized in that: be equipped with at the preceding top of square stainless steel inside pipe wall and stretch position limit switch entirely, full reduced position limit switch is installed at the back top of square stainless steel inside pipe wall.
During use Stainless Steel Tube is fixed on the housing of flexible hydraulic jack, the prong sheet is embedded the piston rod head circular disc limit of flexible hydraulic jack.The pulling Stainless Steel Rule stretched out when flexible hydraulic jack protracted, on the Stainless Steel Rule through hole when the bearing, the signal that the photosignal transmitter sends receives into the pulse train signal through the hole by photoelectric signal receiver, pulse signal send control computer promptly as can be known oil cylinder piston bar castor from, piston rod retraction as flexible hydraulic jack also can obtain the pulse train signal, thereby learns the piston rod retraction distance of flexible hydraulic jack.When the oil cylinder piston bar reached limit position, the spacing collision block of Stainless Steel Rule afterbody moved the position limit switch of stretching entirely that is contained in the preceding top of square stainless steel inside pipe wall, and output is stretched signal entirely and given control computer.When the piston rod of the flexible hydraulic jack of oil bounces back, the spacing collision block of Stainless Steel Rule afterbody makes the full reduced position limit switch action that is contained in top behind the square stainless steel inside pipe wall, export full reduced signal and give control computer, should practical sensor function various, can cut down expenses significantly, and can satisfy architectural required precision.
Claims (2)
1. flanging ruler type photoelectricity stroke sensor, comprise square Stainless Steel Tube, it is characterized in that: one bearing is arranged on the top of Stainless Steel Tube, photosignal transmitter and relative photoelectric signal receiver are installed on bearing, one Stainless Steel Rule is arranged, every 2 millimeters a through hole is arranged on the Stainless Steel Rule, the through hole that penetrates on the Stainless Steel Rule on the bearing is positioned at square Stainless Steel Tube, tail dress at Stainless Steel Rule is equipped with spacing collision block, spacing collision block and square stainless steel inside pipe wall are slidingly matched, and on the Stainless Steel Rule top that is positioned at the bearing hole outside prong sheet are installed.
