Description

Technical Field

[0001] The utility model relates to the technical field of instrument detection, in particular to an instrument drop resistance performance detection device. Background Art

[0002] In the mining industry, workers are often required to carry portable mining instruments into mines to detect the richness of various minerals in the mines. The road conditions in mines are poor. In order to prevent mining instruments from being damaged during transportation, manufacturers will test their drop resistance when producing these mining instruments to determine the instrument's impact resistance.

[0003] When conducting drop resistance tests on mining instruments, workers must drop them from different heights, from low to high. They then perform performance tests on the instruments after they've been dropped until they're damaged, thereby completing a rating of the instruments' impact resistance. However, in actual use, this testing method requires the instruments to be dropped multiple times, requiring testers to lift them multiple times. Mining instruments are heavy, and this process of lifting them multiple times consumes significant physical effort, increasing their workload. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-Figure 5, an instrument drop resistance performance testing device includes a ruler 2, a first baffle 1 is horizontally fixed to the bottom of the ruler 2, and a second baffle 3 is horizontally fixed to the top of the ruler 2, a first turntable 101 is rotatably mounted on the first baffle 1, and a second turntable 301 is rotatably mounted on the second baffle 3, a first slide bar 4 and a second slide bar 5 are vertically fixed on the side opposite to the first turntable 101 and the second turntable 301, the first slide bar 4 is slidably connected to the first load-bearing plate 401 through a first connecting structure, and the second slide bar 5 is slidably connected to the second load-bearing plate 501 through a second connecting structure, a cylinder frame 11 is fixed on the first baffle 1, and a cylinder 12 is fixed on the cylinder frame 11, and a driving block 13 is fixed on the output end of the cylinder 12 to drive the first load-bearing plate 401 and the second load-bearing plate 501 to slide vertically, and a baffle 7 is slidably connected to the ruler 2 through a sliding structure to limit objects on the first load-bearing plate 401 and the second load-bearing plate 501.

[0026] like Figure 3 The figure shows the initial state of the device. When in use, first adjust the height of the baffle 7 and confirm its height by the ruler 2. Then, place the instrument to be tested on the first load-bearing plate 401. Secondly, drive the first load-bearing plate 401 upward by the driving block 13 on the output end of the cylinder 12, so that the first load-bearing plate 401 moves up to abut against the bottom of the baffle 7. Finally, drive the second turntable 301 to rotate 180 degrees.

[0027] When the second turntable 301 rotates 180 degrees, the first load-bearing plate 401 and the second load-bearing plate 501 will also rotate synchronously. Since the upper surface of the first load-bearing plate 401 is against the bottom of the baffle 7, the instrument to be detected on the first load-bearing plate 401 will be blocked by the baffle 7 during the rotation process, and the instrument to be detected will not move. When the first load-bearing plate 401 is removed from under the baffle 7, the instrument to be detected is no longer supported by the first load-bearing plate 401. At this time, the instrument to be detected begins to free fall, and the instrument to be detected is free fall. During the movement, since the second load-bearing plate 501 and the first load-bearing plate 401 rotate 180 degrees synchronously, after the first load-bearing plate 401 moves away from under the baffle 7, the second load-bearing plate 501 will move to the first baffle 1 directly under the baffle 7, and the landing point of the free fall of the instrument to be tested is also directly under the baffle 7. Therefore, after the free fall of the instrument to be tested is completed, its landing point is just on the second load-bearing plate 501, and the first load-bearing plate 401 will slide down to the lowest point along the first slide bar 4 under the action of gravity. At this time, a drop test is completed.

[0028] After completing a drop test, the instrument to be tested is located on the second load-bearing plate 501. At this time, the cylinder 12 is started first, and the cylinder 12 drives the driving block 13 to move down to the bottom of the first baffle 1, and then the cylinder 12 drives the driving block 13 to move up. In the process of the driving block 13 moving up, the second load-bearing plate 501 will be driven to move up, thereby lifting the instrument to be tested on the second load-bearing plate 501. When the second load-bearing plate 501 moves up and rests against the bottom of the baffle 7, the cylinder 12 is closed. At this time, the steps of the above-mentioned drop test are repeated to complete the second drop test.

[0029] According to the requirements of the instrument test, the above-mentioned one-time and two-time drop tests can be repeated to continuously complete the drop test of the instrument. There is no need for the tester to manually lift the instrument to be tested many times, thereby reducing the physical labor intensity of the tester.

[0030] like Figure 8 and Figure 9 As shown, the first connecting structure includes a first sleeve 402, the first sleeve 402 is fixed on the first load-bearing plate 401, the first sleeve 402 is slidably fitted on the first slide rod 4, a first mounting groove 406 is provided at the bottom of the first sleeve 402, a first connecting rod 404 is fixed in the first mounting groove 406, a first valve plate 403 is rotatably mounted on the first connecting rod 404, a first spring 405 is sleeved on the first connecting rod 404, one end of the first spring 405 is fixed to the inner wall of the first mounting groove 406, and the other end is fixed to the first valve plate 403, so as to reset the first valve plate 403.

[0031] like Figure 10 and Figure 11 As shown, the second connecting structure includes a second sleeve 502, the second sleeve 502 is fixed on the second load-bearing plate 501, the second sleeve 502 is slidably fitted on the second slide rod 5, a second mounting groove 506 is opened at the bottom of the second sleeve 502, a second connecting rod 504 is fixed in the second mounting groove 506, a second valve plate 503 is rotatably mounted on the second connecting rod 504, a second spring 505 is sleeved on the second connecting rod 504, two ends of the second spring 505 are fixed to the inner wall of the second mounting groove 506, and the other two ends are fixed to the second valve plate 503, so as to reset the second valve plate 503.

[0032] The first connecting structure is used to connect the first load-bearing 401 to the first slide bar 4, and the second connecting structure is used to connect the second load-bearing plate 501 to the second slide bar 5. Through the cooperation between the first valve plate 403 and the first mounting groove 406, and the cooperation between the second valve plate 503 and the second mounting groove 506, the first connecting structure and the second connecting structure will only be subject to the upward support force given by the driving block 13, so that the driving block 13 can easily lift the first load-bearing 401 and the second load-bearing plate 501.

[0033] like Figure 6and Figure 7 As shown, the sliding structure includes a sliding member 8, which is slidably fitted on the scale 2. A screw hole 9 is provided on the sliding member 8, and a positioning bolt 10 is fitted into the inner thread of the screw hole 9. The baffle 7 is fixedly connected to the outer wall of the sliding member 8.

[0034] The sliding member 8 can slide on the scale 2 to adjust the height. The positioning bolt 10 is used to fix the sliding member 8 on the scale 2. The sliding member 8 on the scale 2 can drive the baffle 7 to move synchronously, thereby facilitating the adjustment and confirmation of the height of the baffle 7.

[0035] like Figure 1 As shown, a driving structure is provided on the second baffle 3 for driving the second turntable 301 to rotate, and the driving structure includes a motor frame 14, a motor 15 is fixedly connected to the motor frame 14, a driving wheel 16 is fixedly connected to the output end of the motor 15, and a driven wheel 6 is fixedly connected to the second turntable 301, and the driving wheel 16 cooperates with the driven wheel 6.

[0036] After the motor 15 is started, the driving wheel 16 rotates, and the rotation of the driving wheel 16 drives the driven wheel 6 to rotate, and the rotation of the driven wheel 6 drives the second turntable 301 to rotate, thereby achieving the purpose of driving the second turntable 301 to rotate 180 degrees through the motor 15.

[0037] Workflow:

[0038] like Figure 3 The figure shows the initial state of the device. When in use:

[0039] First, the height of the baffle 7 is adjusted by sliding the sliding member 8 vertically on the ruler 2, and the height of the baffle 7 is confirmed by the ruler 2. After the height adjustment is completed, the positioning bolt 10 can be tightened.

[0040] Then, the instrument to be tested is placed on the first load-bearing plate 401, and the driving block 13 on the output end of the cylinder 12 drives the first load-bearing plate 401 upward, so that the first load-bearing plate 401 moves up until it rests against the bottom of the baffle 7, and the instrument to be tested reaches the target height.

[0041] Finally, the motor 15 is started to drive the second turntable 301 to rotate 180 degrees. During the rotation of the second turntable 301 by 180 degrees:

[0042] The first load-bearing plate 401 and the second load-bearing plate 501 will also rotate synchronously therewith. Since the upper surface of the first load-bearing plate 401 is against the bottom of the baffle 7, the instrument to be detected on the first load-bearing plate 401 will be blocked by the baffle 7 during the rotation process, and the instrument to be detected will not move. When the first load-bearing plate 401 is moved away from under the baffle 7, the instrument to be detected is no longer supported by the first load-bearing plate 401. At this time, the instrument to be detected begins to perform free fall motion. During the free fall motion of the instrument to be detected, due to the The second load-bearing plate 501 and the first load-bearing plate 401 rotate 180 degrees synchronously. Therefore, after the first load-bearing plate 401 moves away from under the baffle 7, the second load-bearing plate 501 will move to the first baffle 1 directly under the baffle 7, and the landing point of the free fall of the instrument to be tested is also directly under the baffle 7. Therefore, after the free fall of the instrument to be tested is completed, its landing point is just on the second load-bearing plate 501, and the first load-bearing plate 401 will slide down to the lowest point along the first slide bar 4 under the action of gravity. At this time, a drop test is completed.

[0043] After completing a drop test, the instrument to be tested is located on the second load-bearing plate 501. At this time, the cylinder 12 is started first, and the cylinder 12 drives the driving block 13 to move down to the bottom of the first baffle 1, and then the cylinder 12 drives the driving block 13 to move up. In the process of the driving block 13 moving up, the second load-bearing plate 501 will be driven to move up, thereby lifting the instrument to be tested on the second load-bearing plate 501. When the second load-bearing plate 501 moves up and rests against the bottom of the baffle 7, the cylinder 12 is closed. At this time, the steps of the above-mentioned drop test are repeated to complete the second drop test.

[0044] According to the requirements of the instrument test, the above-mentioned one-time and two-time drop tests can be repeated to continuously complete the drop test of the instrument. There is no need for the tester to manually lift the instrument to be tested many times, thereby reducing the physical labor intensity of the tester.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
