[0024] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.
[0025] As Figure 1-2 shown, a multi-stage buffer mechanism is an interception system for the tractor parking of an electromagnetic catapult device. Because the electromagnetic catapult speed is extremely fast, it can only be buffered and decelerated by increasing the damping, and it cannot be stopped immediately. Specifically, in combination with Figure 1 and Figure 2 shown;
[0026] The first guide wheel 1 and the second guide wheel 2 arranged on the same horizontal plane and vertically rotatably arranged;
[0027] The annular rope 4, the part of which located between the two first guide wheels 1 and the two second guide wheels 2 forms a first interception structure and a second interception structure;
[0028] The third guide wheel 5 located between the two first guide wheels 1, lower than the horizontal plane where the first guide wheel 1 is located, and horizontally rotatably arranged, and the third guide wheel 5 is used to make the annular rope 4 downward.
[0029] Consisting of three fourth guide wheels 51 arranged on the same horizontal plane, vertically rotationally assembled, and arranged at the vertices of a triangle;
[0030] And the three fourth guide wheels 51 arranged at the vertices of a triangle form a wire winding wheel set, and one end of the annular rope 4 is sleeved on the wire winding wheel set.
[0031] Furthermore, in combination with Figure 1 shown, a guide rail groove 31 is opened on the installation platform 3, and the second guide wheel 2 is slidably located on the guide rail groove 31, wherein:
[0032] A guide roller 32 coaxially arranged with the guide rail groove 31 is fixedly installed on the installation platform 3, a damping spring 33 is sleeved on the guide roller 32, and the damping spring 33 is connected to a guide sliding member 34 on the guide roller 32;
[0033] A swing arm 35 slidably assembled with the second guide wheel 2 is rotatably arranged on the installation platform 3, and a first connecting member 36 is rotatably arranged between the swing arm 35 and the guide sliding member 34.
[0034] It should be noted that in the default state of the damping spring 33, the distance between the second guide wheel 2 and the first guide wheel 1 is the largest.
[0035] Even further, in combination with Figure 1It can be seen that sliding grooves 61 arranged coaxially and symmetrically are formed on the substrate 6 in the embodiment. The two fourth guide wheels 51 respectively slide on the sliding grooves 61 and maintain relative movement. A hydraulic damper 7 is fixedly installed on the substrate 6. A swing rod 8 is rotatably arranged on the substrate 6. A second connecting member is rotatably arranged between one end of the swing rod 8 and the output end of the hydraulic damper 7, and a third connecting member is rotatably connected between the other end of the swing rod 8 and the fourth guide wheel 51 sliding in the sliding groove 61.
[0036] Moreover, the length of the rotating shaft of the swing rod 8 from the second connecting member is greater than the length of the rotating shaft from the third connecting member.
[0037] In the above technology, when the tractor moves quickly and is contacted to form a first interception structure between the two first guide wheels 1 for interception, under traction, the second guide wheel 2 moves in the guide rail groove 31 and thus approaches the first guide wheel 1. During this process, the swing arm 35 moves along with the movement of the second guide wheel 2, and thus the push slider 34 is pushed by the first connecting member 36 to slide toward the first guide wheel 1 side, so that the damping spring 33 deforms to provide a damping force. As the first interception structure deforms to coincide with the second interception structure formed between the two second guide wheels 2, it cooperates to buffer and make the tractor stagnate.
[0038] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
