In order to realize more effective rotating connection between the planing pipe 2 and the anti-creeping teeth 1, an adjusting component 4 is arranged between the anti-creeping teeth 1 and the planing pipe 2.
With continued reference to fig. 2, one end of the adjusting assembly 4 is fixedly connected to the anti-creep teeth 1, and the other end thereof is rotatably connected to the planning pipe 2, so that the anti-creep teeth 1 are rotatably connected to the planning pipe 2.
Specifically, an adjusting hole 25 is formed at one end of the planing pipe 2 close to the climbing-preventing teeth 1, the opening direction of the adjusting hole 25 faces the climbing-preventing teeth 1, a threaded structure is arranged on the inner wall of the adjusting hole 25, and the adjusting component 4 is arranged in the adjusting hole 25.
More specifically, the adjustment assembly 4 includes an adjustment swivel bearing 42, a positioning stop 43, and an adjustment member 41.
The peripheral surface of the adjusting rotating shaft is connected with the inner wall of the adjusting hole 25; the number of the positioning stops 43 is at least two, the positioning stops 43 are respectively positioned at two sides of the adjusting rotary bearing 42, and the positioning stops 43 are connected with the inner wall of the adjusting hole 25 through threads. In this embodiment, the number of the rotating bearings is preferably 2, and the number of the positioning stoppers 43 is 3, and the positioning stoppers are uniformly distributed on two sides of the rotating bearings, so as to position the adjusting rotating bearing 42; the positioning stoppers 43 are not in contact with the adjusting member 41, and the positioning stoppers 43 located on the outer side, that is, the gaps between the positioning stoppers 43 located at the two end portions of the adjusting member 41 and the adjusting member 41 are sealed by the sealing rings, thereby playing a role of dust prevention. By adopting the above structure, the positioning stopper 43 functions to position the adjusting rotary bearing 42, so as to limit the movement of the adjusting rotary shaft in the horizontal axis direction, thereby enabling the rotary bearing to be stably arranged in the adjusting hole 25.

When a train collides, the climbing preventive teeth 1 receive an impact force and then transmit the impact force to the adjusting members 41, the adjusting members 41 horizontally move and transmit the impact force to the planing pipe 2, so that the planing pipe 2 is rotationally moved toward the base 3, and the planing tools 33 in the base 3 begin to cut the planing pipe 2.
Further, as shown in fig. 8 and 9, an anti-disengaging positioning groove 5 is further provided on an end surface of the adjusting member 41, and the structure of the anti-disengaging positioning groove 5 is matched with the anti-disengaging assembly provided on the planing tube 2, so that the anti-disengaging assembly can be inserted into the anti-disengaging positioning groove 5; meanwhile, an inclined boss 51 is arranged at one end of the anti-falling positioning groove 5 close to the anti-climbing teeth 1.

Specifically, the structure of the retaining positioning groove 5 is matched with the structure of the retaining connecting piece 23. When the impact force does not reach the preset value, the anti-dropping connecting piece 23 can be stably inserted into the anti-dropping positioning groove 5, so that the relative rotation between the adjusting piece 41 and the planing pipe 2 is limited. Since the planing tube 2 cannot rotate, the planing tool 33 cannot cut the planing tube 2, so that the anti-creep device cannot absorb energy before the impact force reaches the preset value.
Simultaneously, through setting up this anticreep subassembly and anticreep constant head tank 5 matched with structure for when the impact that the train received reached the default, anticreep connecting piece 23 can be along inclined plane boss 51 roll-off anticreep constant head tank 5, thereby makes planing pipe 2 and prevent realizing independent rotation between the tooth 1. Specifically, when a train is impacted, the climbing preventive teeth 1 are impacted and then transferred to the adjusting pieces 41, the adjusting pieces 41 are impacted and then move towards the adjusting holes 25, thereby leading the anti-drop connecting piece 23 to be dropped off along the inclined plane boss 51 designed at the front end of the anti-drop positioning slot 5, at this time, the top of the anti-drop connecting piece 23 is ejected out from the anti-drop fixing block 22, because the anti-drop connecting piece 23 is occluded with the sealing ring, the anti-drop connecting piece 23 is prevented from falling back or dropping off, the pushed-out anti-drop connecting piece 23 no longer has the function of limiting the rotation of the planing pipe 2, thereby realizing independent rotation between the planing pipe 2 and the climbing-proof teeth 1, releasing the rotation freedom degree of the planing pipe 2 and the climbing-proof teeth 1, therefore, the anti-climbing device can be matched with the existing non-rotary type anti-climbing device for use, and the energy absorption effect is not influenced, so that the anti-climbing device has universality.
Further, a buffer member is provided between the adjusting piece 41 and the bottom of the adjusting hole 25 in the horizontal axis direction. The buffer part comprises a rigid spherical support part 6 and a rubber pile 7, one end of the rigid spherical support part 6 is connected with the adjusting part 41, and the other end of the rigid spherical support part is connected with the rubber pile 7; the rubber pile 7 is connected with the bottom of the adjusting hole 25. In this example, the rigid spherical support 6 is fixedly connected to the rubber pile 7 by means of rubber vulcanization. By adopting the structure, the contact area between the adjusting piece 41 and the rigid spherical support piece 6 can be reduced, the friction force when the adjusting piece 41 rotates relative to the rigid spherical support piece 6 is reduced, the rubber pile 7 can buffer the impact force between the adjusting piece 41 and the rigid spherical support piece 6, and the initial contact rigidity between the planing tool 33 and the planing pipe 2 is reduced.
By last, through mutually supporting of base 3 and planing pipe 2, and through the position and the structure of rational design guide 32 and planing sword 33 on base 3 to make planing pipe 2 under the guide effect of guide 32 and guide way 21, can rotate the formula and move towards base 3, thereby increased the route that planing sword 33 cut, increased the distance that anti-creep device effectively absorbed energy promptly. Through adopting above structure from this, under the prerequisite that does not increase the energy-absorbing power value and do not increase the anticreeper weight, reasonable effectual energy-absorbing distance that has increased, reasonable effectual total energy absorption who promotes the anticreeper promptly for the anticreeper can satisfy in the train to the higher requirement of energy absorption. Therefore, the technical problem that the planing energy-absorbing anti-creeper in the prior art cannot reasonably and effectively meet the high requirement of the train on the energy absorption is solved.
For a clearer explanation of the present application, the working principle of the present invention will be further explained by taking the embodiments shown in fig. 1 to 7 as examples:
when a train collides, the climbing-prevention teeth 1 are impacted and then sequentially transmitted to the adjusting piece 41, the rigid spherical support piece 6 and the rubber pile 7. Because the rubber pile 7 is compressible, the adjusting piece 41 can move towards the adjusting hole 25 when being impacted, so that the anti-drop connecting piece 23 is dropped out along the inclined plane boss 51 designed at the front end of the anti-drop positioning groove 5, and the ejected anti-drop bolt no longer has a limiting effect on the rotation of the planing pipe 2.
When the rubber pile 7 is compressed to the limit, the impact force is transmitted to the planing tube 2, so that the planing tube 2 is rotationally moved toward the base 3, and the planing tool 33 in the base 3 starts to cut the planing tube 2. Since the planing tube 2 is rotationally moved along the axis by the guiding action of the guide grooves 21 and the guide members 32, the total length of the planing operation is increased, i.e., the energy absorbing distance is increased.
Through adopting above structure from this, under the prerequisite of guaranteeing rational design energy absorption value, through the make full use of to 2 energy-absorbing routes of planing pipe, effectively increase the energy-absorbing distance, promote anti-creep device's total energy absorption, reduce the deceleration value of collision in-process, reduce the injury to the member. Therefore, the technical problem that the planing energy-absorbing anti-creeper in the prior art cannot reasonably and effectively meet the high requirement of the train on the energy absorption is solved.
