Background technology
Electric precipitator positive plate is the eccentric suspended structure of single-point, includes a plurality of positive plates, hanging beam and vibrating rod, and electric precipitator positive plate connects between the positive plate of cathode line and ground connection of high-voltage DC power supply and forms high-voltage electric field; Because negative electrode generation corona discharge, gas are by ionization, electronegative gaseous ion is under the effect of electric field force; The motion of rising sun sun plate is collided with dust granules at the volley, then makes the grit lotus with negative electricity; Grit after charged under the effect of electric field force, also rising sun anode movement, arrive anode after; Emit negative charge, grit then is deposited on the positive plate, and the gas that is purified is discharged outside the fly-ash separator.The requirement of its antianode plate is that product is straight, intensity is high, rigidity is strong, is difficult for distortion; But producer all is to accomplish under the horizontality for the check of positive plate owing to huge its detection of positive plate build at present; Detection for linearity and torsion resistance all is not the detection data under the truth; Because the horizontal positioned positive plate is distortion naturally under gravity, the linearity for positive plate can't detect especially thus, has a strong impact on reliability of products and usability.
The utility model content
The utility model provides a kind of simple in structure, positive plate vertical detection platform that can detect the real linearity of positive plate, torsion resistance.
A kind of positive plate vertical detection platform, described positive plate vertical detection platform comprises: the erecting frame of positive plate, the work for inspection frame that stands vertically are installed; Erecting frame cooperates with guide rail on the work for inspection frame to be controlled by motor-driven hanging wheel group through the pulley of being located at the bottom and moves up and down; The positive plate side is provided with the check perpendicular line.This kind detection platform stands vertically positive plate through the erecting frame cooperation work for inspection frame makes positive plate be in plumbness and avoids being out of shape naturally because of what gravity caused; By the check perpendicular line of positive plate side as testing tool; The testing staff passes through the spacing that perpendicular line and positive plate are checked in the measurement of a plurality of positions up and down; Carry out spacing data and contrast the linearity that draws positive plate according to spacing data amplitude of variation size, the more little linearity of amplitude is good more.The quantity of check perpendicular line can for about two spacings through two check perpendicular line relative positive plates, carry out the torsion resistance that the spacing data contrast draws positive plate, the spacing data of two relative positive plates of check perpendicular line is good more near torsion resistance more.The utility model records the true linearity and the torsion resistance of positive plate through under plumbness, adopting the check perpendicular line, in time finds the existing quality problems of positive plate and repair to obtain good quality production.
Have the detection platform of pressing close to positive plate more than two on the described work for inspection frame; The testing staff is by detection platform about the staircase of work for inspection frame side; Detection platform is a platy structure for the testing staff provides the workbench of multimetering, obtains the spacing data of a plurality of check perpendicular line and positive plate.
Described staircase is divided into two sections of the first half and the latter halfs, connects work for inspection frame both sides respectively.Through two sections staircases are set in the falsework both sides, not only make work for inspection frame steadily of centre of gravity and practiced thrift manufacturing cost.
The described work for inspection frame bottom that stands vertically is provided with the horizontal guide rail frame, and there is matching relationship in the pulley of horizontal guide rail frame and erecting frame.The horizontal guide rail shelf structure has solved present positive plate is horizontality when producing and dispatch from the factory transportation and can not convert the technical matters that plumbness also just can not the detection of straight lines degree into.Pulley matching relationship through horizontal guide rail frame and erecting frame makes the erecting frame of horizontal positioned under the hanging wheel group of the work for inspection frame that stands vertically drives, become plumbness by horizontality, just positive plate is become plumbness from horizontality and promptly obtains a kind of real detected state.
Described work for inspection frame that stands vertically and horizontal guide rail frame junction are provided with tilting section, become plumbness with the erecting frame that makes things convenient for positive plate from horizontality.
The top crossbeam of described positive plate and erecting frame is connected through screw rod makes positive plate be in free state and actual user mode extremely near so that obtain real more measurement data.
The length of described positive plate is 5-15 rice, and the long more detection that can not carry out linearity, torsion resistance more of the length of prior art antianode plate has embodied the technological merit of the utility model more.
Described check perpendicular line is hung on the top crossbeam of erecting frame, and the check perpendicular line increases the detection data under the same detection platform for two or more.
The utility model detects linearity, the torsion resistance obtain positive plate through positive plate vertical detection platform multiple spot under the positive plate plumbness, reduces the positive plate defective of dispatching from the factory, and improves reliability of products and practicality.
Embodiment
A kind of positive plate vertical detection platform as shown in Figure 1 comprises: the erecting frame 6 of positive plate 3, the work for inspection frame 1 that stands vertically are installed; Erecting frame 6 cooperates with guide rail 9 on the work for inspection frame 1 to be controlled by motor-driven hanging wheel group through the pulley 10 of being located at the bottom and moves up and down; Positive plate 3 sides are provided with check perpendicular line 4.Have the detection platform 5 of pressing close to positive plate 3 more than two on the work for inspection frame 1, the testing staff is by the staircase of work for inspection frame 1 side detection platform 5 about in the of 2.Work for inspection frame 1 bottom that stands vertically is provided with horizontal guide rail frame 7, and the work for inspection frame 1 and horizontal guide rail frame 7 junctions that stand vertically are provided with tilting section.There is matching relationship in horizontal guide rail frame 7 with the pulley 10 of erecting frame 6.Check perpendicular line 4 is hung on the top crossbeam of erecting frame 6, and check perpendicular line 4 is two or more.
Be divided into two sections of the first half and the latter halfs as structure optimization staircase 2, connect work for inspection frame 1 both sides respectively.
For making positive plate 3 be in free vacant state, positive plate 3 is connected through screw rod with the top crossbeam of erecting frame 6 that positive plate 3 can be around screw rod 360 degree rotations thus.
The length of positive plate 3 is that this length of 5-15 rice is for general positive plate length can certainly proper extension at present.
