Abstract
The invention relates to a method for stepless control of length of a viscous damper when the damper is mounted. In the method, eccentric sleeves are arranged between a double ear ring base of the damper and a pin shaft of the damper, and fixed on the double ear ring base by a positioning bolt; when the damper is mounted, firstly a spherical hinge base of the damper is inserted in the double ear ring base, one eccentric sleeve is sleeved in a hole on one side of the double ear ring base; the pin shaft is inserted in the damper from the side on which the eccentric sleeve is sleeved; the other eccentric sleeve is sleeved on the other side of the double ear ring base; the eccentric sleeves are turned, so that the eccentric sleeves are sleeved between the double ear ring base and the pin shaft, and the double ear ring base closely contacts the mounting surface; the eccentric sleeves are tightly locked by positioning bolts; and finally the double ear ring base is fixed, the whole process of mounting the damper is completed. Compared with the prior art, the method of the invention has the advantages of low cost, simple and convenient operation, high precision and great improvement of the mounting efficiency.
Description
Technical field
The present invention relates to bridge vibration damping antidetonation field, be specifically related to stepless length regulating method in a kind of mounting course of viscous damping device.
Background technology
Viscous damper generally is made of two ears ring seats and damper and connector thereof, its installation form be mainly reflected in ears ring seat bottom surface towards difference, shown in Fig. 1～2, left ears ring seat 1 is fixed on the bridge 7, auris dextra bridge chair 2 is fixed on the bearing pad stone 8, after two ears ring seats fix, because it is very high that the installation accuracy of damper 5 requires, gap between bearing pin 9 and left ears ring seat 1 hole and right ears ring seat 2 holes has only tens, after the bearing pin 9 of damper 5 one ends is inserted well, the bearing pin of the other end is as long as a little range error just can't be inserted, so it is extremely important that distance adjustment just becomes, the regulative mode that extensively adopts when damper is installed has two kinds at present, first kind: by the left ball pivot seat 3 of damper 5 one ends or the screw thread spinning in and out of right ball pivot seat 4 are regulated, this technical disadvantages is one, regulate loaded down with trivial detailsly, the locking nut 6 of damper 5 one ends must be unscrewed, regulate again, be transferred to locking at last behind the position.Two, can't carry out step-less adjustment during adjustable range, it is discontinuous that each adjustable range is jumped section, and all be before not beginning to install, just to regulate for large-scale damper is general when adopting this adjusting, because at the scene under the condition, this adjusting cannot be carried out at all during installation.Second kind: during installation when an end damper insert good after, by real-time measurement error in length, the steel plate of the thickness that meets the demands of reprocessing, metal mat is reached the purpose of adjustable range to ears ring seat bottom, listened fixedly damper of oscillating bearing 10 after installing, this method is more loaded down with trivial details and difficult when implementing.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of simple to operation in order to overcome the defective that above-mentioned prior art exists, precision height, stepless length regulating method in the high mounting course of viscous damping device of installation effectiveness.
Purpose of the present invention can be achieved through the following technical solutions: stepless length regulating method in a kind of mounting course of viscous damping device, it is characterized in that, this method is between the bearing pin of the ears ring seat of damper and damper eccentric bushing to be set, and eccentric bushing is fixed on the ears ring seat with positioning bolt, during installation, ball pivot seat with damper inserts between the ears ring seat earlier, and eccentric bushing is inserted in the hole of ears ring seat one side, insert damper with bearing pin from the one side that is with eccentric bushing, be inserted in another eccentric bushing at ears ring seat another side then, the rotating eccentricity cover, eccentric bushing is inserted between ears ring seat hole and the bearing pin, ears ring seat and installed surface are developed, lock eccentric bushing with positioning bolt then, fixing ears ring seat at last, the damper whole erection is finished.
Described ears ring seat has two, but the center to center distance between the eccentric bushing step-less adjustment two ears ring seats.
Described ears ring seat adopts bolt or welding to fix.
The external diameter of described eccentric bushing is consistent with the internal diameter nominal diameter in ears ring seat hole.
The endoporus of described eccentric bushing is consistent with the external diameter nominal size of bearing pin.
The external diameter of described eccentric bushing and internal diameter are not concentric circles.
Compared with prior art, the present invention increases an eccentric bushing between ears ring seat and bearing pin, when the center to center distance between the two ears ring seats is either large or small, can reach the purpose of step-less adjustment center to center distance by the rotating eccentricity cover, after mixing up center to center distance, use fixedly eccentric bushing of positioning bolt, eccentric bushing is no longer rotated.Both satisfy the requirement of center to center distance, guaranteed the correct installation of damper, satisfied the requirement in tens gaps of pin and ears ring seat hole again, guaranteed the accurate transmission of damping force.This method expense is cheap, simple to operation, and the precision height greatly must improve installation effectiveness.
Description of drawings
Fig. 1 is the structural representation of existing viscous damper;
Fig. 2 is that the A of Fig. 1 is to part sectioned view;
Fig. 3 is the structural representation of the eccentric bushing of damper of the present invention;
The eccentric bushing structural representation that Fig. 4 reduces for damper center to center distance of the present invention;
The eccentric bushing structural representation that Fig. 5 increases for damper center to center distance of the present invention.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Shown in Fig. 3～5, stepless length regulating method in a kind of mounting course of viscous damping device, this method is to add eccentric bushing 11 between right ears ring seat 2 and bearing pin 9, the external diameter of eccentric bushing 11 is consistent with the internal diameter nominal diameter in ears ring seat 2 holes, fit tolerance is E8/h8, the endoporus of eccentric bushing 11 is consistent with the external diameter nominal size of bearing pin 9, fit tolerance is F8/h8, but the external diameter of eccentric bushing 11 and internal diameter are not concentric circles, the off-centre of eccentric bushing is designed to 15mm, this micromatic setting just can be regulated ± distance of 15mm so, also add eccentric bushing between left side ears ring seat 1 and the bearing pin, during installation, earlier damper ball pivot seat is inserted between the ears ring seat, and an eccentric bushing is inserted in the hole of ears ring seat one side, insert damper with bearing pin from the one side that is with eccentric bushing, be inserted in another eccentric bushing at ears ring seat another side then, suitable rotating eccentricity cover, eccentric bushing is inserted between ears ring seat hole and the bearing pin, guarantee that ears ring seat and installed surface develop, lock eccentric bushing with positioning bolt then, at last with bolt or the fixing ears ring seat of welding, the end of damper whole erection.Above-mentioned eccentric bushing can be decided eccentric degree according to actual instructions for use.This method expense is cheap, simple to operation, and the precision height greatly must improve installation effectiveness.
