Description

Soft steel damper test device

Technical Field

The utility model relates to an instrument and meter technical field especially relates to a mild steel attenuator test device.

Background

Engineering structure shock attenuation control is a new field of engineering structure antidetonation. The technology does not adopt the traditional anti-seismic method of a reinforcing structure to improve the anti-seismic capacity of the structure, but adopts the way of adjusting and changing the dynamic parameters of the structure to obviously attenuate the vibration reaction of the structure, thereby effectively protecting the safety of the internal facilities of the structure in strong earthquakes.

However, in the existing stage of the damper testing machine, due to the unbalanced loading, the unbalanced loading and the uneven lateral force of the test sample (damping wall) can occur to different degrees in the test process, and the accuracy of the test data is further affected, so that the improvement is needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming present sample and can appear not the uneven circumstances of atress that results in to appear the unbalance loading to the equidimension ground when detecting to influence the not enough of the accuracy of experimental data, and a mild steel attenuator test device that proposes.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a testing device for a mild steel damper comprises four upright posts, wherein a construction and grinding crossbeam is fixedly and slidably arranged between the four upright posts, an actuator is rotatably connected between the two upright posts, one end of the actuator is connected with an L beam through two ball hinges, the lower end of the L beam is abutted against a damping wall, and a construction and grinding type four-bar mechanism is jointly arranged on the construction and grinding crossbeam and the L beam;

the four-bar mechanism comprises two first cross beam arms which are rotatably connected to a cross beam under construction and research, two second cross beam arms are rotatably connected to the L beam, one ends of the two first cross beam arms are connected with mounting blocks, one ends of the two second cross beam arms are respectively rotatably connected to the mounting blocks, and a connecting arm is rotatably connected between the two mounting blocks.

Preferably, four corners of the lower end of the building and grinding crossbeam are connected with first guide chain hoisting seats, and the lower ends of the four first guide chain hoisting seats are fixed on the L beam.

Preferably, the vertical actuator is connected to the construction and grinding crossbeam through bolts and nuts.

Preferably, two of them stand all are connected with second and lead chain hoist and mount seat.

Compared with the prior art, the utility model has the beneficial effects that the utility model discloses a cooperation between formula four-bar linkage and the L roof beam is researched and developed, reaches and makes the damping wall receive the horizontal force all the time when the atress, guarantees the purpose of the loaded accuracy of power, guarantees simultaneously that the damping wall can not go out the plane when the atress, does not have the influence of yawing force, can adjust according to the high wait position of damping wall simultaneously for test space has more selections.

Drawings

Fig. 1 is a front view of the present invention;

fig. 2 is a sectional view of the present invention.

In the figure, 1 upright post, 2 building and grinding cross beams, 3 a first cross beam arm, 4 a second cross beam arm, 5L beams, 6 damping walls, 7 connecting arms, 8 a second guide chain hoisting seat and 9 actuators.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples, which are provided for the purpose of illustration only and are not intended to limit the scope of the invention.

Referring to fig. 1-2, a mild steel damper test device comprises four upright posts 1, a construction and grinding crossbeam 2 is fixedly and slidably arranged between the four upright posts 1, the construction and grinding crossbeam 2 is connected with a vertical actuator through bolts and nuts, four corners of the lower end of the construction and grinding crossbeam 2 are connected with first guide chain hoisting seats, the lower ends of the four first guide chain hoisting seats are fixed on a L beam 5, the two upright posts 1 are connected with a second guide chain hoisting seat 8, the two upright posts 1 are rotatably connected with an actuator 9, one end of the actuator 9 is connected with the lower end of a L beam 5L beam 5 through two spherical hinges and is abutted against a damping wall 6, and a construction and grinding type four-bar linkage mechanism is arranged on the construction and grinding crossbeam 2 and the L beam 5;

referring to fig. 1-2, the four-bar linkage includes two first beam arms 3 rotatably connected to the cross beam 2 under construction, two second beam arms 4 rotatably connected to the L beam 5, the two first beam arms 3 are connected to mounting blocks at one ends, the two second beam arms 4 are respectively rotatably connected to the mounting blocks at one ends, and a connecting arm 7 is rotatably connected between the two mounting blocks.

The utility model discloses in, when testing, earlier according to damping wall 6's height, adjust L roof beam 5's height and actuator 9's position, make L roof beam 5 contradict on damping wall 6, after fixed, actuator 9 promotes about L roof beam 5, can make damping wall 6 receive the effect of horizontal force all the time when L roof beam 5 removes, detect damping wall 6, when promoting L roof beam 5 and appearing all the other effort, because four-bar linkage's effect, guarantee L roof beam 5 steady movement, prevent that damping wall can go out the plane when the atress, there is the influence of yawing force, the condition that leads to experimental data error to appear takes place.
