Detailed Description
Example one
Please refer to fig. 1 to 3, which are schematic structural views of a penetration-resistant testing mechanism for a safety net 12 according to the present invention. The resistant test mechanism that runs through of safety net 12 includes: the test device comprises a bearing support 10, a test support 20 arranged on one side of the bearing support 10, an electromagnetic fixing seat 21 connected to one end of the test support 20, and a clamping arm 30 which is provided with at least two circumferences and is hinged on the electromagnetic fixing seat 21. It is contemplated that the penetration testing mechanism of the safety net 12 may further include other functional components and specific structures, such as electrical connection components, mounting structures, etc., which are well known to those skilled in the art, and therefore, will not be described in detail herein.
The upper end of the bearing support 10 is provided with a bearing platform arranged on the ground, the bearing platform is provided with a mounting hole 11, the inner wall of the mounting hole 11 is correspondingly connected with the outer contour of the safety net 12, and the mounting hole 11 corresponds to the size of the safety net 12 and presents a test state in use. It can be expected that, due to the flexibility of the material of the safety net 12, the middle part of the safety net 12 after being tiled is provided with a sinking groove, and the test rod 23 freely falls onto the safety net 12 without generating a larger offset distance.
The test support 20 and the bearing support 10 can be arranged separately or integrated into a whole mechanism. The main part of test support 20 is the top that L shape and test support 20's one end is located bearing support 10, be equipped with elevating gear 22 on the test support 20, elevating gear 22 includes along the lift chain 221 of test support 20 setting and one end connection electromagnetism fixing base 21, and a setting is in the chain drive mechanism 222 of test support 20 and drive lift chain 221, chain drive mechanism 222 drive lift chain 221 drive electromagnetism fixing base 21 goes up and down in safety net 12 top, the height of adjustment electromagnetism fixing base 21. In this embodiment, the lower portion of the electromagnetic fixing seat 21 is an output end, and the structure magnetically attracted by the electromagnetic magnet is a conventional one in the art, and the specific structure is not described again.
The test rod 23, the electromagnetism is connected the lower extreme of electromagnetism fixing base 21 through the break-make of electromagnetism, realizes the free fall of test rod 23, and the whereabouts of test rod 23 is also adjusted to the high while of adjustment electromagnetism fixing base 21 and is tested the height, also can descend through electromagnetism fixing base 21 and carry out the recovery of test rod 23 in addition after the test is accomplished, further avoids artifical centre gripping to retrieve, improves work efficiency. The upper end circumference outer wall of test rod 23 is equipped with the spacing convex part 25 that a plurality of intervals set up, and spacing convex part 25 sets up in the upper end of test rod 23, can not influence the test result, reduces the roll nature of test rod 23 on safety net 12 simultaneously, because the bi-polar height of test rod 23 is different, forces the one-way roll of test rod 23 to become the rolling of ring type, reduces the roll excursion distance of test rod 23.
The clamping arm 30 has at least two circumferential settings and is hinged on the electromagnetic fixing seat 21, in this embodiment, the clamping arm 30 includes two arc-shaped arms 32 arranged at intervals, and the pushing roll 31 is hinged at one end of the arc-shaped arm 32 far away from the electromagnetic fixing seat 21. Rotation through arc arm 32 drives and pushes away material roller 31 and roll on safety net 12, can be under the condition of not damaging safety net 12, with test bar 23 propelling movement to electromagnetism fixing base 21 below, does benefit to electromagnetism fixing base 21 and accomplishes recovery work to test bar 23 after descending.
The height of the lower end of the clamping arm 30 is lower than that of the lower end of the electromagnetic fixing seat 21, when the pushing roller 31 is not in contact with the safety net 12, the pushing roller 31 can surround to form a closed ring, and the inner diameter of the closed ring is larger than the outer diameter of the lower end of the electromagnetic fixing seat 21. The clamping arm 30 firstly contacts the surface of the safety net 12, specifically, the electromagnetic fixing seat 21 descends, the pushing roller 31 firstly contacts the safety net 12 and then outwards opens, even when contacting the testing rod 23 on the safety net 12, the opening operation can be completed, the electromagnetic fixing seat 21 ascends along with the lifting operation, the pushing roller 31 folds, the testing rod 23 is forced to return to the falling central point, the pushing roller 31 forms a closed ring to limit the testing rod 23 on the safety net 12, and finally the electromagnetic fixing seat 21 descends again to complete the magnetic attraction recovery of the testing rod 23.
The electromagnetic fixing seat 21 is provided with an angle limiting portion 24 abutted against the clamping arm 30, and the angle limiting portion 24 limits the clamping arm 30 to rotate to be close to the electromagnetic fixing seat 21 so as to avoid interference with the electromagnetic fixing seat 21.
This security net 12 is able to bear or endure to run through accredited testing organization has reduced the roll nature of test stick 23 at security net 12, simultaneously at whole recovery process, does not need the recovery that manual operation can accomplish test stick 23, improves work efficiency, can not harm security net 12 in addition.
