Problems solved by technology

The method of using the safety pin can play a role in protecting the personal safety of the operator, but this method is guaranteed by the operator's operation steps, and the operator often forgets to take out the safety pin on the guide post after replacing the waveform generator. The bolt directly releases the brake on the worktable, so that the worktable collides with the safety bolt with a certain impact force, which may bend the safety bolt and damage the worktable, or cause the bolt to sink into the worktable, strain the guide column, and cause damage to the equipment part. Components are scrapped, which may even harm the personal safety of the operator

Embodiment 1

[0026] Example 1 see figure 2 As shown, in this embodiment, a hole is opened on the safety plug 2, and the switching device 3 is placed in the hole of the safety plug 2. During the test, when replacing the waveform generator, raise the worktable 5 to a set height, so that the worktable 5 is a certain distance above the pin hole on the guide post 1, and after starting the brake, insert the safety pin 2, and the switch device 3 obtains the signal Feedback to the control system, so that the control system sends an action command to be controlled, and the equipment enters a locked state, so that the work surface cannot be lowered; after the safety plug 2 is taken out, the control system can issue an action command, and the equipment is unlocked.

Embodiment 2

[0027] Example 2 see image 3 As shown, in this embodiment, the switch fixing base 4 is fixed on the base 6 , and the switch 2 is installed on the switch fixing base 4 and placed on the side of the safety bolt 2 . During the test, when replacing the waveform generator, raise the worktable 5 to a set height, so that the worktable 5 is a certain distance above the pin hole on the guide post 1, and after starting the brake, insert the safety pin 2, and the switch device 3 obtains the signal Feedback to the control system, so that the control system sends an action command to be controlled, and the equipment enters a locked state, so that the work surface cannot be lowered; after the safety plug 2 is taken out, the control system can issue an action command, and the equipment is unlocked.

Embodiment 3

[0028] Embodiment 3 see Figure 4 As shown, in this embodiment, the switch fixing base 4 is fixed on the work surface 5 , and the switch device 3 is installed on the switch fixing base 4 and placed above the safety plug 2 . During the test, when replacing the waveform generator, raise the worktable 5 to a set height, so that the worktable 5 is a certain distance above the pin hole on the guide post 1, and after starting the brake, insert the safety pin 2, and the switch device 3 obtains the signal Feedback to the control system, so that the control system sends an action command to be controlled, and the equipment enters a locked state, so that the work surface cannot be lowered; after the safety plug 2 is taken out, the control system can issue an action command, and the equipment is unlocked.

Abstract

The invention discloses a safety chain protection mechanism and a safety chain protection method for a vertical impact test-bed. The safety chain protection mechanism comprises a safety plug and a switching element, wherein the switching element is connected to a control system of the vertical impact test-bed. According to the safety chain protection method, a signal is sent to the control system of the vertical impact test-bed by the switching element when the safety plug is inserted into a guide pillar of the vertical impact test-bed, so that the control system cannot send an action command for descending an operating platform of the vertical impact test-bed, so as to realize the safety chain protection of the vertical impact test-bed. The safety chain protection mechanism provided by the invention has the advantages that the structure is simple, the cost is low, the operation method is convenient, the potential safety hazard caused by faulty operation in working process of the vertical impact test-bed can be eliminated and the practical working requirement is met.

Description

technical field [0001] The invention particularly relates to a safety interlock protection mechanism and method for a vertical impact test bench in the technical field of mechanical environmental testing, which are used to improve the safety performance of the vertical impact test bench during use. Background technique [0002] The vertical impact test bench is a kind of mechanical environment test equipment, which is used to simulate the single or repeated impact environment suffered by the product during transportation or use, so as to assess the reliability of the function and the integrity of the structure of the test piece in this environment. sex. The waveform of the vertical impact test bench is realized by various waveform generators placed under the worktable. The elastic material is used to generate a half-sine waveform, the plastic material is used to generate a triangular waveform, and the rigid material is used to generate a square wave. The waveform generator ...
