Description

Technical Field

[0001] The invention belongs to the technical field of self-rescuer experiments, and in particular relates to an experimental device for resisting rolling impact of a self-rescuer. Background Art

[0002] A self-rescuer is a portable respiratory protection device used by personnel entering a mine to prevent poisoning by harmful gases or suffocation due to lack of oxygen when a fire, gas, coal dust explosion, or coal and gas outburst occurs underground. A self-rescuer is a small, light, and easy-to-carry device for protecting personal respiratory organs. The self-rescuer generally contains an oxygen tank and a calcium hydroxide tank. The calcium hydroxide absorbs the carbon dioxide in the exhaled gas, thereby reducing the carbon dioxide content in the airbag, allowing the exhaled oxygen to be fully recycled and used, thereby increasing the duration of use.

[0003] Since unexpected situations may cause rolling impacts to the self-rescuer in the well, in order to ensure that the self-rescuer can be used normally after the rolling impact, the self-rescuer needs to be subjected to an anti-rolling impact test before leaving the factory to verify the self-rescuer's anti-rolling impact performance. The existing anti-rolling impact test equipment for self-rescuers simply fixes the self-rescuer inside the test box and rotates it horizontally at different speeds. It cannot actually simulate the special situation underground, so the anti-rolling impact performance test of the self-rescuer is relatively limited. Summary of the invention

If the second shifting ring 60 is shifted to the left, the fourth clutch block 56 on the fourth transmission rod 55 is disengaged from the fifth clutch block 57 on the second rotating rod 48, so that the test box 4 will not drive the second sun gear 45 to rotate when rotating.

[0086] The first attitude, such as Figure 1 , 4 , 6 as shown:

[0087] Loosen both first locking bolts 29, push the first shifting ring 36 to the right, and when the first sliding sleeve 28 slides to one end of the axis of the first sun gear 6, loosen the first shifting ring 36, and tighten the first locking bolt 29 at one end of the first sun gear 6. At this time, the first spring 39 starts to rebound, the second transmission rod 31 slides in a direction away from the first transmission rod 30, and the first clutch block 32 on the second transmission rod 31 engages with the second clutch block 33 on the first rotating rod 22.

[0088] Loosen both fourth locking bolts 53, move the second shifting ring 60 to the left, and when the second sliding sleeve 52 slides to one end of the axis of the second sun gear 45, loosen the second shifting ring 60, and tighten the second locking bolt 44 at one end of the second sun gear 45.

[0090] At this time, the left corner and the right corner of the test box 4 are on the same horizontal line, the first transmission shaft 9, the first transmission cylinder 10, the second transmission shaft 15, and the second transmission cylinder 16 are all on the same horizontal line, and the first transmission shaft 9, the first transmission cylinder 10, the second transmission shaft 15, and the second transmission cylinder 16 are all located on the axis of the first rotating rod 22 and the second rotating rod 48.

[0091] The control driving motor 24 starts to rotate, and the driving motor 24 drives the first fixed sleeve 21 to rotate through the mutually meshing driving gear 25 and the driven gear 26, and the first fixed sleeve 21 drives the first sun gear 6 to rotate, and the first sun gear 6 drives the first planetary gear 20 and the first planetary carrier 7 to rotate, wherein the first planetary gear 20 revolves around the axis of the first sun gear 6 and rotates around its own axis, and the first planetary carrier 7 rotates around the axis of the first sun gear 6. The first planetary carrier 7 drives the first rotating rod 22 to rotate.

By controlling the different speeds of the driving motor 24, the test box 4 is driven to rotate at different speeds, and then the horizontal rotation of the self-rescuer at different speeds is tested, and finally the self-rescuer after horizontal rotation is tested to confirm whether its performance is perfect.

[0093] The second group of postures, such as Figure 2 As shown:

[0094] Loosen both first locking bolts 29, push the first shifting ring 36 to the right, and when the first sliding sleeve 28 slides to one end of the axis of the first planetary gear 20, loosen the first shifting ring 36 and tighten the first locking bolt 29 at one end of the first planetary gear 20. At this time, the first spring 39 starts to rebound, the second transmission rod 31 slides in a direction away from the first transmission rod 30, and the first clutch block 32 on the second transmission rod 31 engages with the third clutch block 40 on the rotating shaft of the first planetary gear 20.

[0095] Loosen both fourth locking bolts 53, move the second shifting ring 60 to the left, and when the second sliding sleeve 52 slides to one end of the axis of the second planetary gear 46, loosen the second shifting ring 60, and tighten the second locking bolt 44 at one end of the second planetary gear 46. At this time, the second spring 63 begins to rebound, the fourth transmission rod 55 slides in a direction away from the third transmission rod 54, and the fourth clutch block 56 on the fourth transmission rod 55 engages with the sixth clutch block 64 on the rotating shaft of the second planetary gear 46.

[0096] At this time, the second locking bolt 44 is in a tightened state, and the second gear ring 43 is fixed and cannot rotate; the third locking bolt 50 is in a loosened state, and the second rotating rod 48 can rotate freely.

[0097] At this time, the left corner and the right corner of the test box 4 are on the same horizontal line, the first transmission shaft 9, the first transmission cylinder 10, the second transmission shaft 15, and the second transmission cylinder 16 are all on the same horizontal line, and the first transmission shaft 9, the first transmission cylinder 10, the second transmission shaft 15, and the second transmission cylinder 16 are all located on the axis of the first planetary gear 20 and the second planetary gear 46.

[0098] The control driving motor 24 starts to rotate, and the driving motor 24 drives the first fixed sleeve 21 to rotate through the mutually meshing driving gear 25 and the driven gear 26, and the first fixed sleeve 21 drives the first sun gear 6 to rotate, and the first sun gear 6 drives the first planetary gear 20 and the first planetary carrier 7 to rotate, wherein the first planetary gear 20 revolves around the axis of the first sun gear 6 and rotates around its own axis, and the first planetary carrier 7 rotates around the axis of the first sun gear 6.

[0099] The first planetary gear 20 drives the second transmission rod 31 to orbit and rotate simultaneously through the first clutch block 32 and the third clutch block 40 that are engaged with each other. The second transmission rod 31 drives the first transmission rod 30 to orbit and rotate simultaneously. The first transmission rod 30 drives the left side of the test box 4 to orbit and rotate simultaneously through the first universal joint 11 and the first transmission shaft 9 and the first transmission cylinder 10 that are plugged into each other. The right side of the test box 4 orbits and rotates simultaneously. The right side of the test box 4 is connected to the second transmission shaft 9 and the first transmission cylinder 10 that are plugged into each other.

[0100] Through the above operation, the test box 4 is controlled to rotate horizontally while revolving around the axis of the first rotating rod 22 and the second rotating rod 48, thereby driving the self-rescuer inside the test box 4 to revolve around the axis of the first rotating rod 22 and the second rotating rod 48 while rotating horizontally. By controlling the different speeds of the driving motor 24, the test box 4 is driven to revolve and rotate at different speeds, and then the self-rescuer is tested for revolving and rotating at different speeds, and finally the self-rescuer after revolving and rotating is tested to confirm whether its performance is perfect.

[0101] The third attitude, such as Figure 3 As shown:

[0102] Loosen both first locking bolts 29, push the first shifting ring 36 to the right, and when the first sliding sleeve 28 slides to one end of the axis of the first sun gear 6, loosen the first shifting ring 36, and tighten the first locking bolt 29 at one end of the first sun gear 6. At this time, the first spring 39 starts to rebound, the second transmission rod 31 slides in a direction away from the first transmission rod 30, and the first clutch block 32 on the second transmission rod 31 engages with the second clutch block 33 on the first rotating rod 22.

[0103] Loosen both fourth locking bolts 53, move the second shifting ring 60 to the left, and when the second sliding sleeve 52 slides to one end of the axis of the second planetary gear 46, loosen the second shifting ring 60, and tighten the second locking bolt 44 at one end of the second planetary gear 46. At this time, the second spring 63 begins to rebound, the fourth transmission rod 55 slides in a direction away from the third transmission rod 54, and the fourth clutch block 56 on the fourth transmission rod 55 engages with the sixth clutch block 64 on the rotating shaft of the second planetary gear 46.

[0104] Since the second transmission rod 31 is connected to the first rotating rod 22, and the fourth transmission rod 55 is connected to the rotating shaft of the second planetary gear 46, the distance between the second transmission rod 31 and the fourth transmission rod 55 becomes longer. Therefore, the first transmission shaft 9 and the first transmission cylinder 10 slide relatively, and the second transmission shaft 15 and the second transmission cylinder 16 slide relatively, so that the distance between the first universal joint 11 and the test box 4 and the distance between the second universal joint 17 and the test box 4 are both lengthened.

[0105] At this time, the height of the right corner of the test box 4 is higher than the height of the left corner of the test box 4, that is, the test box 4 as a whole is at an inclined angle, the self-rescuer fixed inside the test box 4 is also at an inclined angle, and the first transmission shaft 9, the first transmission cylinder 10, the second transmission shaft 15, and the second transmission cylinder 16 are all on an inclined straight line with the right higher and the left lower.

[0106] At this time, the second locking bolt 44 is in a loosened state, and the second ring gear 43 can rotate freely inside the second ring gear groove; the third locking bolt 50 is in a tightened state, and the second rotating rod 48 is fixed and cannot rotate.

[0107] The control driving motor 24 starts to rotate, and the driving motor 24 drives the first fixed sleeve 21 to rotate through the mutually meshing driving gear 25 and the driven gear 26, and the first fixed sleeve 21 drives the first sun gear 6 to rotate, and the first sun gear 6 drives the first planetary gear 20 and the first planetary carrier 7 to rotate, wherein the first planetary gear 20 revolves around the axis of the first sun gear 6 and rotates around its own axis, and the first planetary carrier 7 rotates around the axis of the first sun gear 6. The first planet carrier 7 drives the first rotating rod 22 to rotate. When the first rotating rod 22 rotates, the second transmission rod 31 is driven to rotate through the first clutch block 32 and the second clutch block 33 that are engaged with each other. The second transmission rod 31 drives the first transmission rod 30 to rotate. The first transmission rod 30 drives the left side of the test box 4 to rotate through the first universal joint 11 and the first transmission shaft 9 and the first transmission cylinder 10 that are plugged into each other. The right side of the test box 4 rotates at the same time. The right side of the test box 4 drives the second universal joint 17 to rotate through the second transmission shaft 15 and the second transmission cylinder 16 that are plugged into each other. The second universal joint 17 drives the left end of the third transmission rod 54 to rotate. The second transmission rod 31 drives the fourth transmission rod 55 to rotate. The fourth transmission rod 55 drives the second rotating rod 48 to rotate. The second rotating rod 48 drives the second planetary gear 46 to rotate around its own axis. Since the second planet carrier 13 is fixed, the position of the second planetary gear 46 is fixed and cannot be changed. Therefore, the second planetary gear 46 drives the second sun gear 45 and the second ring gear 43 to rotate at the same time when it rotates.

[0108] Through the above operation, the test box 4 is controlled to tilt and rotate, thereby driving the self-rescuer inside the test box 4 to rotate at an inclined angle. By controlling the different speeds of the driving motor 24, the test box 4 is driven to tilt and rotate at different speeds, and then the tilting and rotating of the self-rescuer at different speeds is tested, and finally the self-rescuer after tilting and rotating is tested to confirm whether its performance is perfect.
