The utility model relates to a serial-connection steel wire rope vibration isolator, which is characterized by consisting of two steel wire rope vibrator isolators vertically connected in series. Each steel wire rope vibration isolator includes an upper clamping board group and a lower clamping board group, slots for clamping steel wire ropes are arranged between two upper clamping boards while slots for clamping steel wire ropes are also arranged between two lower clamping boards, the steel wire rope penetrates through and is wound between the upper clamping board group and the lower clamping board group clockwise from one end of the lower clamping board group to the middle, then penetrates and is wound anticlockwise to the other end of the lower clamping board group, steel wire rope sections in front of the upper clamping board group and the lower clamping board group are tightly clamped in the slots vertically aligned, and steel wire rope sections in the rear of the upper clamping board group and the lower clamping board group are tightly clamped in the slots vertically adjacent to each other. The serial-connection steel wire rope vibration isolator consisting of the two steel wire rope vibration isolators connected in series reduces occupied space, meets the requirement of being installed in narrow spaces of instruments and equipment, increases height after series connection, increases perpendicular allowable deformation, reduces rigidity, and increases vibration isolation and impact resistance effects.

Description

The tandem steel-wire isolator

Technical field

The utility model relates to a kind of vibration isolator, especially relates to a kind of tandem steel-wire isolator, be mainly used in various spaces long and narrow, require that rigidity is little, natural frequency is low, occasion that vibration and impact resistance are had relatively high expectations.

Background technique

Conventional at present steel-wire isolator using method is that single steel-wire isolator is installed and used separately, owing to need reduce vibration isolator rigidity and self natural frequency in some specific use occasion, so when designing and selecting steel-wire isolator for use, must strengthen the width and the height of vibration isolator, and need use thicker wire rope, therefore, the volume of steel-wire isolator is bigger, need take the bigger device space, this just needs to strengthen the space of system equipment, for the long and narrow instrument and equipment of some installing spaces, just can't use single steel-wire isolator, the using scope of steel-wire isolator is restricted.

The model utility content

The applicant has carried out research and has improved at above-mentioned problem, and a kind of tandem steel-wire isolator is provided, and satisfies the demand that is installed on the instrument and equipment long and narrow space, reduces rigidity simultaneously, improves vibration isolation and shock resistance effect.

In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:

A kind of tandem steel-wire isolator, be connected in series up and down by two steel-wire isolators and constitute, described steel-wire isolator comprises punch holder group and die holder group, the punch holder group constitutes by two punch holders are fixedly connected, the die holder group constitutes by two die holders are fixedly connected, reach the slotted eye that is equipped with the clamped wire rope between two die holders between two punch holders, the spacing between the slotted eye equates, and the slotted eye consistency from top to bottom of the slotted eye of punch holder group and die holder group; Wire rope is worn around between punch holder group and the die holder group clockwise from an end of die holder group, wear around to punch holder group and die holder group intermediate portion, wire rope is by counterclockwise wearing around the other end to the die holder group, and wire rope clamps in the slotted eye of the slotted eye of punch holder group and die holder group; The length of cable of punch holder group and die holder group front side is clamped in the slotted eye of punch holder group and die holder group consistency from top to bottom, the length of cable of punch holder group and die holder group rear side is clamped in the neighbouring slotted eye of punch holder group and die holder group, the wire rope of the left and right sides is seen the wire rope ovalize with the center symmetry plane symmetry of punch holder group and die holder group from the side-looking direction perpendicular to the center symmetry plane.

Further:

In described two steel-wire isolators, the die holder group of a steel-wire isolator is fixedlyed connected with the die holder group of another steel-wire isolator.

Technique effect of the present utility model is:

The disclosed a kind of tandem steel-wire isolator of the utility model is made of two steel-wire isolator series connection, reduces occupation space, satisfies the demand that is installed on the instrument and equipment long and narrow space; The series connection back highly increases, and vertical permission amount of deformation increases, and rigidity reduces, and improves vibration isolation and shock resistance effect.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

As shown in Figure 1, 2, 3, the utility model is connected in series up and down by two steel-wire isolators 100 and constitutes.Single steel-wire isolator 100 comprises punch holder group 1 and die holder group 2, punch holder group 1 constitutes by two punch holders are fixedly connected, die holder group 2 constitutes by two die holders are fixedly connected, be provided with a plurality of slotted eyes 101 of clamped wire rope between two punch holders, be provided with a plurality of slotted eyes 201 of clamped wire rope between two die holders, spacing L between the spacing between the slotted eye 101 of punch holder group 1 and the slotted eye 201 of die holder group 2 all equates, and the slotted eye 101 of punch holder group 1 and slotted eye 201 consistencies from top to bottom of die holder group 2.Wire rope 3 is worn around between punch holder group 1 and the die holder group 2 clockwise from an end of die holder group 2, wear around to punch holder group 1 and die holder group 2 intermediate portions, wire rope 3 is by counterclockwise wearing around the other end to die holder group 2, and wire rope 3 is clamped in the slotted eye 201 of the slotted eye 101 of punch holder group 1 and die holder group 2.The length of cable 301 of punch holder group 1 and die holder group 2 front sides is clamped in the slotted eye of punch holder group 1 and die holder group 2 consistencies from top to bottom, the length of cable 302 of punch holder group 1 and die holder group 2 rear sides is clamped in the neighbouring slotted eye of punch holder group 1 and die holder group 2, the wire rope 3 of the left and right sides is with the center symmetry plane A symmetry (as Fig. 1) of punch holder group 1 and die holder group 2, from seeing wire rope 3 ovalizes (as Fig. 3) perpendicular to the side-looking direction of center symmetry plane A, wire rope 3 wear that pitch of the laps is several to be determined according to designing requirement.In the present embodiment, in two steel-wire isolators 100, the die holder group 2 of a steel-wire isolator is fixedlyed connected by screw-nut 4 with the die holder group 2 of another steel-wire isolator.Member of the present utility model all adopts stainless steel material to make.

Because the utility model adopts two steel-wire isolators to be in series, its rigidity can reduce makes an appointment with half, natural frequency reduces about 1.5 times, enlarged the vibration isolated area, more help isolation to dither, according to vibrational theory, it is many more that system frequency is lower than the external environment condition vibration frequency, and its vibration isolating effect is good more.Owing to allow amount of deformation to double, so the tandem wire rope has enough big amount of deformation to be used for consuming impact energy when being subjected to impacting, add the impact energy that damping consumes, its impact resistance can increase about 50%.
