Furthermore, the end of the left way twist wire rope (8) and the end of the right way twist wire rope (9) are respectively clamped in the same direction in two adjacent slots which are symmetrically arranged at both sides of the center line of the upper inner clamping plate (4), so that the left way twist and the right way twist wire ropes are respectively arranged in the symmetrical slots on the both sides of the upper and the lower inner clamping plates. In addition, the outer clamping plate is buckled and pressed on the inner clamping plate, and is connected with the inner clamping plate by screws, and as a result, the wire rope is pressed tightly and fixed.

Description

Two sth. made by twisting are to cable wire shock absorber

Technical field

The utility model relates to engineering shock insulation (shaking) field, relates generally to a kind of two sth. made by twisting to cable wire shock absorber.

Background technique

The isolator that is used for shock insulation (shaking) engineering (comprising the instrument and equipment shock insulation) at present can be divided into four classes, the first kind is the steel spring isolator, it is big that it has a bearing capacity, the rigidity regulation range is wide, stable performance, simple structure, but volume is big, damping is little, needs adaptive damper (buffer) to use in engineering; Second class is rubber cushion assembly (comprising types such as steel plate laminated rubber, plumbous heart laminated rubber), and it has big damping, but vertically little to moving displacement amount, the shock insulation rate is also relatively low, only uses in earthquake engineering; The 3rd class is the pneumatic spring isolator, and it has rigidity, Adjustable Damping, and moving displacement amount is bigger, but engineering needs source of the gas in using; The 4th class is a cable wire shock absorber, and it is to utilize modern seismic isolation theory and the novel isolated component developed, is widely used in shock insulation fields such as multiple dynamic power machine, electronic equipment, haulage vehicle; As application number is " 02263881.4 ", and name is called the patent of " cable wire shock absorber ", and it is the long strip cable wire shock absorber, it vertically have non-linear software feature to rigidity, damping is big, and is corrosion-resistant; But on technique for coiling, adopt the steel cable coil to be around in the slotted eye of punch holder and die holder, after wire rope lays out clamping plate by a clockwise coil, oppositely wear counterclockwise around to the other end; Because wire rope adopts single sth. made by twisting can produce in the static(al) deformation process to, isolator and reverses, shock isolator easily rotates in engineering is used.

Summary of the invention

It is wide that the purpose of this utility model provides a kind of using scope, and difficult generation is reversed, bearing capacity height, two the sth. made by twisting to cable wire shock absorber that moving displacement amount is big.

The purpose of this utility model can adopt following technological scheme to realize: it is made up of to wire rope to wire rope and friendship right-laid punch holder group, die holder group, friendship left-hand lay.Upper and lower clamping plate group is made of inner splint and external splint, attachment screw respectively, and inner splint and external splint side direction have the groove that wire rope is installed.In adjacent two grooves of last inner splint center line symmetry with same direction respectively clamping hand over left-hand lay to the steel wire end with hand over right-laid to the steel wire end, make and hand over a left side, hand over right-laid in wire rope places the monosymmetric groove of upper and lower inner splint respectively, external splint is withheld on inner splint, and connect with screw, compress and fixing wire rope.

The utility model cable wire shock absorber, wire rope is made up of seven strands, per share 19 steel wire coilings, and wirerope diameter is 12.5～19.5mm.The more little isolator rigidity of the wire rope lay pitch is big more; Wirerope diameter increases rigidity and increases; The coiling number of turns increases rigidity and increases; The clamping plate width increases initial stiffness and increases.The cable wire shock absorber cross section is oval, and minor axis increases rigidity and diminishes; Major axis increases rigidity and becomes big; The clamping plate width directly influences long and short axis scale.The damping of cable wire shock absorber be by isolator in the stress deformation process strand with strand, strand and silk, silk and thread between the dry friction of slippage generation cause that stress deformation is big more, slippage is big more, damping is big more, so damping is non-linear.The utility model is reasonable in design, simple in structure, easy for installation, vertically to have non-linear software feature, damping ratio increases with amplitude, dynamic magnifier is little, and temperature accommodation is big, the oil resistant salt spray resistance, the anti-organic solvent corrosion and fatigue life-span is long, the shock insulation of the various complicated such as vibrations that are applicable to vibration, impact and explode.The shock isolation system of the utility model design is with stressed increase, and the distortion of isolator increases, and the natural frequency of vibration of shock isolation system reduces, and the shock insulation rate increases.The key technical indexes that reaches is as follows:

Basic static capacity (BSC) rating: 2KN, 4KN, 8KN;

Corresponding maximum allowable misalignment amount: 65mm, 75mm, 75mm;

Damping ratio: 0.1～0.2
