Abstract
The utility model discloses a vibration damping seat for an engineering machine. The seat is arranged on a rack through a vibration damping mechanism; the vibration damping mechanism comprises a steel wire rope vibration isolator arranged below the seat, and a vibration isolation support used for applying inclined upward thrust on the seat; the vibration isolation support comprises a vibration isolation ball and a support post; the vibration isolation ball is of a hollow structure; a clamp platform is arranged on the vibration isolation ball, so that the vibration isolation ball is arranged on the joint of the seat back and the seat cushion in a clamping manner, the vibration isolation ball is also provided with a channel allowing the support post to enter the vibration isolation ball, the outer wall forming the vibration isolation ball is of a double-layer hollow structure into which a flexible material is injected for damping vibration. According to the vibration damping seat, the vibration isolation support is arranged on the back of the seat, the steel wire rope vibration isolator is arranged at the bottom of the seat, thus vibration of an engineering vehicle generated during operation is offset by the steel wire rope vibration isolator and the vibration isolation ball of the vibration isolation support, vibration of the seat is isolated, and fatigue and damage to health of a driver due to vibration of seat are avoided.
Description
Technical field
The utility model relates to the vibration damping field of construction machinery and equipment, specifically a kind of construction machinery and equipment shock absorbing seat.
Background technology
Construction machinery and equipment, as trac. etc., in the process of moving, or larger ambient vibration can reduce travelling comfort, reduces work efficiency, and serious the healthy of people that also can endanger, causes somatic damage.For such situation, need to adopt necessary vibration damping or vibration isolation measure.Existing seat is just simply arranged in operator's compartment, there is no actv. vibration reducing measure.Steel-wire isolator is a kind of high-performance vibration reduction device, not only can isolate extraneous vibration transmission, improves the dynamic characteristic of vibration system, can also effectively alleviate the powerful effect of impacting.To improving travelling comfort, guarantee that health is very favourable.
Utility model content
There is no good vibration isolation effect and cause the problem that chaufeur health is damaged for solving the seat of existing construction machinery and equipment, the utility model provides a kind of construction machinery and equipment shock absorbing seat, by steel-wire isolator and vibration isolation support are set, thereby significantly eliminate vibration that construction machinery and equipment motion the produces impact on seat.
The utility model is that the technical scheme that solves the problems of the technologies described above employing is: a kind of construction machinery and equipment shock absorbing seat, seat is arranged in frame by damper mechanism, described damper mechanism comprises and is arranged on the steel-wire isolator of under-seat and for apply the vibration isolation support of thrust obliquely to seat, this vibration isolation support comprises vibration isolation ball and pillar stiffener, vibration isolation ball is hollow structure, on it, there is a Ka Tai so that it is fastened on the chair back and chair cushion junction, on vibration isolation ball, also having one allows pillar stiffener to enter its inner passage, the outer wall that forms vibration isolation ball is double layer hollow structure, in it, be filled with flexible material to subdue vibration, described pillar stiffener bottom is fixed in frame, its top is fixed on the inside of vibration isolation ball by spring assembly after through the passage on vibration isolation ball.
Described pillar stiffener is obliquely installed, and by its bottom to top towards with seat front towards, with provide to seat be tilted to before and application force upwards.
In the utility model, rock rotation or front and back that vibration isolation ball can carry out to a certain degree centered by the end of pillar stiffener, and in the utility model, it is vibration insulator that the flexible material of filling in the outer wall of vibration isolation ball also can change into.
Beneficial effect: the utility model uses vibration isolation support to support seat by the words rear portion at seat, the bottom of seat arranges steel-wire isolator simultaneously, the vibration that makes like this engineering truck produce in the time of operation is offset by the vibration isolation ball of steel-wire isolator and vibration isolation support, thereby prevent the vibration of seat, fatigue and the health damage of chaufeur are avoided causing due to seat vibration, improve the cushioning performance of Tractor operator seat with this, to improve operator's saddle travelling comfort, guarantee chaufeur work efficiency.

Detailed description of the invention
As shown in the figure, a kind of construction machinery and equipment shock absorbing seat, seat 1 is arranged in frame by damper mechanism, described damper mechanism comprises and is arranged on the steel-wire isolator 2 of seat 1 below and for apply the vibration isolation support of thrust obliquely to seat, this vibration isolation support comprises vibration isolation ball 3 and pillar stiffener 6, vibration isolation ball 3 is hollow structure, on it, there is a Ka Tai so that it is fastened on the chair back and chair cushion junction, the geomery of the shape and size of Ka Tai and the chair cushion of seat and the chair back matches, so that vibration isolation ball 3 can just snap into the intersection of the chair back and chair cushion, on vibration isolation ball 3, also having one allows pillar stiffener 6 to enter its inner passage, the width of this passage is larger than the size of pillar stiffener 6, so that vibration isolation ball 3 can have certain motion surplus around pillar stiffener 6, the outer wall that forms vibration isolation ring 3 is double layer hollow structure, also just say by an inner housing and body skin, inner housing inside is the hollow part of holding pillar stiffener 6 ends, it between inner housing and body skin, is hollow structure, its inside is filled with flexible material 4 or vibration insulator to subdue vibration, described pillar stiffener 6 bottoms are fixed in frame, its top is fixed on the inside of vibration isolation ball 3 by spring assembly 5 after through the passage on vibration isolation ball 3, the vibration of body is eliminated by spring assembly 5 and vibration isolation ball 3 after pillar stiffener 6 like this.
Described pillar stiffener 6 is obliquely installed, and by its bottom to top towards with seat 1 front towards, with provide to seat 1 be tilted to before and application force upwards; That is to say, should be the intersection that withstands on the chair back and chair cushion to top from pillar stiffener 6 bottoms.
