Description

Technical Field

[0001] The utility model relates to a test platform, in particular to a buffer horizontal impact dynamic test platform. Background Art

[0002] Buffers are widely used industrial products. The performance of buffers directly affects the operation and safety of equipment. At present, the design, development and inspection of buffers are generally solved by theoretical calculation and actual use effect verification. Some material buffers (such as rubber and polyurethane buffers) are usually statically inspected by mechanical testing machines. However, structural buffers (such as hydraulic liquid-gas buffers) need to be tested and inspected under dynamic conditions in order to be accurately and scientifically designed and manufactured. In other words, the scientific rationality of structural buffers can only be guaranteed by accumulating data and building models under dynamic test conditions.

[0003] Therefore, it becomes an urgent problem to propose a buffer horizontal impact dynamic test platform with reasonable structure and convenient operation. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a buffer horizontal impact dynamic test platform for carrying out impact tests on structural buffers under dynamic conditions.

[0006] Preferably, the end of the buffer is vertically connected to a connecting plate, and the buffer displacement detection device is fixedly installed next to the buffer. The buffer displacement detection device is a displacement sensor or a distance sensor. When the buffer displacement detection device is a displacement sensor, the displacement sensor is used to detect the displacement of the connecting plate along the axial direction of the buffer. When the buffer displacement detection device is a distance sensor, the buffer displacement detection device is used to detect the distance from it to the connecting plate along the axial direction of the buffer.

[0007] Further preferably, the impact trolley driving structure includes a driving motor and a transmission chain, the driving motor is fixed on the platform seat and located behind the impact trolley, the transmission chain is connected to the driving motor and is arranged parallel to the track, a stopper is arranged on the transmission chain, and a limiting ring cooperating with the stopper is arranged at the rear of the impact trolley. The transmission chain is used to push the impact trolley through the cooperation of the stopper and the limit ring under the drive of the driving motor, thereby giving the impact trolley an impact speed.

[0008] Further preferably, there are two limit rings, which are symmetrically arranged at the rear of the impact trolley.

[0009] Further preferably, a photoelectric sensor is arranged on the side of the platform seat for detecting whether the impact trolley appears on a preset optical path perpendicular to the transmission chain. When the impact trolley appears on the preset optical path, the controller controls the drive motor to stop working. At this time, the block no longer moves forward, and the impact trolley continues to move forward due to kinetic energy and impacts the buffer, wherein the controller is respectively connected to the photoelectric sensor and the drive motor.

[0010] Further preferably, an operation panel is also provided on the platform seat, and a switch for controlling the drive motor is provided on the operation panel.

[0011] Further preferably, the platform seat is also provided with a computer, and the buffer displacement detection device and the force sensor are both connected to the computer for sending detection data to the computer.

[0012] The buffer horizontal impact dynamic test platform provided by the utility model has a simple structure and is convenient for testing, and can provide a large amount of test data for the later performance analysis of the buffer. Specifically: the buffer horizontal impact dynamic test platform can drive the impact trolley through the impact trolley driving structure, and then realize the impact on the buffer. During the impact process, the impact force on the buffer can be obtained through the force sensor, and the length change data of the buffer can be obtained through the buffer displacement detection device. Later, by analyzing the above-mentioned impact force data and the length change data of the buffer, the performance parameters of the buffer can be obtained. BRIEF DESCRIPTION OF THE DRAWINGS

When the impact trolley 2 appears on the preset optical path, the controller controls the drive motor 3 to stop working. At this time, the block 12 no longer moves forward, and the impact trolley 2 continues to move forward due to kinetic energy and impacts the buffer 9. The controller is respectively connected to the photoelectric sensor and the drive motor 3, and is used to receive information from the photoelectric sensor and control the drive motor to stop working.
