Embodiment 1

[0024]SeeFigure 1~3In the embodiment of the present invention, a steel structure shock-absorbing support includes a support body 6, a chassis 1, and a shock-absorbing unit. The bottom of the support body 6 is fixedly installed with a chassis 1. In this embodiment, the The chassis 1 is preferably welded and fixed with the support body 6 to increase the supporting area. The shock absorption unit includes a driving gear 20, a driven gear 16, a screw rod 11, a movable plate 19, a first spring 10, a movable rod 14, The first connecting rod 8, the top rod 7 and the second spring 12, the support body 6 is provided with a mounting cavity, the upper part of the mounting cavity is provided with a mounting plate 5 for fixing and connecting the steel structure, and the top of the support body 6 is provided with a supply The steel structure is movably inserted into the perforation, the mounting plate 5 is slidably connected to the support body 6, and the screw rod 11 is rotatably installed at th...

Embodiment 2

[0027]SeeFigure 4 The difference between the embodiment of the present invention and the embodiment 1 is that the edge of the chassis 1 is threaded with a positioning drill rod 23 to further improve the stability.

[0028]The working principle of the present invention is: when in use, when the vibration causes the mounting plate 5 to move downwards, the first spring 10 and the second spring 12 play the role of damping, and the spiral rod 11 can also act as a shock absorber to the mounting plate 5 in the vertical direction. For deceleration and buffering, the mounting plate 5 drives the spiral rod 11 to rotate, the spiral rod 11 drives the threaded section 13 to rotate, and the threaded section 13 drives the movable plate 19 to move upwards, further compressing the first spring 10, and the first spring 10 has better shock absorption At the same time, the screw rod 11 drives the driving gear 20 to rotate, the driving gear 20 drives the driven gear 16 to rotate, the driven gear 16 drives ...

Abstract

The invention discloses a steel structure damping type support, relates to the technical field of steel structures, and mainly aims at solving the problem that an existing steel structure is poor in damping performance. The shock absorption device comprises a support body, a chassis and a shock absorption unit, the shock absorption unit comprises a driving gear, a driven gear, a screw rod, a movable plate, a first spring, a movable rod, a first connecting rod, an ejector rod and a second spring, and the shock absorption unit further comprises an inner gear ring, a second connecting rod, a pushrod and an elastic plate. The device is provided with a damping unit, and the first spring and the second spring achieve the damping effect. A screw rod can also decelerate and buffer the mounting plate in the vertical direction, the mounting plate drives the screw rod to rotate, the screw rod drives the threaded section to rotate, the threaded section drives the movable plate to move upwards tocompress the first spring, the first spring plays a better damping effect, and the screw rod drives the driven gear to rotate through the driving gear. Finally, an ejector rod is driven to move upwards, a second spring is compressed, the damping efficiency is improved, and buffering and damping of the mounting plate are enhanced through an elastic plate.

Description

Technical field[0001]The invention relates to the technical field of steel structures, in particular to a steel structure shock-absorbing support.Background technique[0002]Steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates, and adopts silanization, pure manganese phosphating, washing and drying, galvanizing and other rust and rust prevention processes. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and easy construction, it is widely used in large-scale factories, venues, super high-rise buildings and other fields. Steel structures are easy to rust. Generally, steel structures need to be derusted, galvanized or painted, and regularly maintained.[0003]The existing steel structure has poor shock absorption performance, and the safety of...
