Shock absorption and shock resistance device of diesel generating set

Technical Field

The patent of the utility model relates to a diesel engine shock attenuation field, concretely relates to diesel generating set shock attenuation antidetonation device.

Background

At present, weaponry is developing towards the direction of off-road motorization, and an off-road vehicle-mounted power station bears environmental vibration impact such as random road vibration, instantaneous impact vibration of bumpy road and the like during motor driving. When the diesel generating set runs, vibration caused by centrifugal inertia force, reciprocating inertia force, connecting rod inertia force and the like exists, and in order to reduce the influence of vibration of the diesel engine and external vibration impact, the diesel engine needs to be connected with a machine set chassis through a shock absorber, and the shock absorber is an elastic body. When the shock absorber is subjected to strong external impact and vibration, the shock absorber can be broken and damaged due to the fact that stress exceeds the limit of elastic force.

Disclosure of Invention

An object of the utility model is to provide a diesel generating set shock attenuation antidetonation device reduces the influence that reduces diesel engine vibration and external vibration and assault, avoids the unit too big rubber layer that leads to the bumper shock absorber of bumper shock absorber deflection when the shock vibration damaged.

The utility model adopts the technical proposal that: a shock absorption and shock resistance device of a diesel generating set comprises a shock absorber, a limiter and a cushion block; the shock absorber is arranged on the unit chassis; the limiting stopper is arranged outside the shock absorber, a gap is reserved between the inner wall of the limiting stopper and the shock absorber, and a through hole is formed in the center of the top of the limiting stopper; the cushion block is arranged in the through hole, and a first mounting hole is formed in the center of the cushion block.

Further, the width of the gap is 2-4 mm.

Furthermore, the cushion block and the limiting stopper are both made of rigid materials.

Further, the cushion block is annular, and the thickness of the cushion block is larger than that of the gap.

Furthermore, second mounting holes are formed in two sides of the bottom of the limiting stopper and connected with the shock absorber and the unit chassis through bolts.

The beneficial effects of the utility model reside in that, avoid diesel generating set direct compression bumper shock absorber, under the condition that does not influence the damping performance of bumper shock absorber itself, protect the bumper shock absorber, avoid the unit bumper shock absorber deflection when impact vibration too big and damaged.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and the present invention is not limited to the specific embodiments disclosed below.

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application belongs. The use of "first," "second," and similar terms in the description and claims of this application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. Also, the use of the terms "a" or "an" and the like do not denote a limitation of quantity, but rather denote the presence of at least one. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships are changed accordingly.

As shown in fig. 1-3, a damping and anti-seismic device of a diesel generator set comprises a damper 1, a limiter 2 and a cushion block 3; the shock absorber 1 is arranged on a unit chassis 9; the limiter 2 is arranged outside the shock absorber 1, a gap 4 is reserved between the inner wall of the limiter and the shock absorber 1, and a through hole 5 is formed in the center of the top of the limiter; the cushion block 3 is arranged in the through hole 5, and a first mounting hole 6 is formed in the center of the cushion block.
