In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments.
As shown in fig. 1 and 2, the invention provides a guide device, which comprises a support member 10, an energy consumption member 20, a guide wheel connecting member 30 and a guide wheel 40, wherein the support member 10 is provided with a connecting hole 111, the energy consumption member 20 and the guide wheel connecting member 30 are arranged in the connecting hole 111, the guide wheel connecting member 30 penetrates through the connecting hole 111, and both ends of the guide wheel 40 are connected with the guide wheel 40.
The working principle is as follows: the guide protection devices are arranged on abutments arranged on two sides of a traveling road surface 60, and a plurality of guide protection devices are uniformly arranged at intervals; when the driving direction of the vehicle deviates and contacts with the abutment, the vehicle contacts with the guide wheel 40 and extrudes the guide wheel 40, so that the energy dissipation part 20 dissipates energy, and meanwhile, the guide wheel 40 rotates to guide the vehicle; the energy consumption of the energy consumption piece 20 reduces the impact kinetic energy of the accident vehicle, and the accident vehicle is guided by the guide wheel 40 to provide the accident vehicle with a forward movement trend.
The device can guide the accident vehicle with smaller impact force to recover the normal operation of the accident vehicle; the loss caused by accidents can be reduced for the accident vehicles with larger impact force.
As shown in fig. 5 and 6, the device is applied to rail transit.
Further, the dissipative element 20 and the guide wheel connecting element 30 together form an interference fit with the connecting hole 111. The interference fit is formed, and when the energy dissipation member 20 is not connected with the guide wheel connecting member 30, the guide wheel connecting member 30 can have a fixing effect when no external force is applied.
Of course, the interference fit between the energy consumption member 20 and the guide wheel connecting member 30 and the connecting hole 111 is not required to be ensured; such as in the case where the dissipative member 20 and the guide wheel connecting member 30 are fixedly coupled or the guide wheel connecting member 30 is not separated from the coupling hole 111 regardless of the displacement (when both ends of the guide wheel connecting member 30 extend to the driving road surface side or when the guide wheel 40 cannot pass through the coupling hole 111 as described below).
Further, the interference of the interference fit is 0. The interference magnitude is 0, and the service life of the energy consumption piece 20 can be prolonged relative to the situation that the excess magnitude is greater than 0, and the assembly of the energy consumption piece 20 and the guide wheel connecting piece 30 in the connecting hole is facilitated.
Further, the energy dissipation member 20 is fixedly connected to the support member 10. The dissipative element 20 is fixedly connected to the support member 10, so as to avoid the position of the dissipative element 20 from shifting during the compression and return process.
Preferably, the energy consumption member 20 is fixedly connected to the guide wheel connection member 30. The energy dissipation member 20 and the guide wheel connecting member 30 are fixed, so that the energy dissipation member 20 and the guide wheel connecting member 30 are prevented from being displaced in the energy dissipation process of the energy dissipation member 20.
Furthermore, a limiting mechanism 13 is arranged outside the energy consumption member 20, the limiting mechanism 13 is fixedly connected with the support member 10, and the width of the limiting mechanism 13 along the compression direction of the energy consumption member 20 does not exceed the maximum compressed width of the energy consumption member 20. In this structure, the energy dissipation member 20 and the support member 10 may be fixedly connected or movably connected, and the energy dissipation member 20 is fixed in the connection hole 111 through the limiting mechanism 13.
Preferably, the stop mechanism 13 is integrally formed with the support member 10.
Now, an example of the structure of the limiting mechanism 13 is illustrated, as shown in fig. 3, the limiting mechanism 13 is two limiting plates disposed on two opposite sides of the connecting hole 111 to limit the energy consumption member 20.
Of course, the structure of the stopper mechanism 13 is not limited to the above-mentioned example.
The reason why the width of the limiting mechanism 13 along the compression direction of the dissipative element 20 does not exceed the maximum compressed width of the dissipative element 20 is to ensure that the normal operation of the dissipative element 20 is not affected and limited by the limiting mechanism 13.
Preferably, the energy consumption member 20 is fixedly connected to the guide wheel connection member 30. The energy dissipation member 20 and the guide wheel connecting member 30 are fixed, so that the energy dissipation member 20 and the guide wheel connecting member 30 can be prevented from being displaced in the energy dissipation process of the energy dissipation member 20.
Further, the guide wheel connection 30 is arranged to be axisymmetric. The axisymmetric guide wheel connector 30 can ensure that two guide wheels 40 are symmetrical, and all the guide wheels 40 which can be contacted with the vehicle are arranged on one guide wheel and face the driving direction of the vehicle; the consistency of the guiding direction of the vehicle is ensured.
Preferably, both ends of the guide wheel attaching part 30 extend toward the traveling road surface side. The distance between the accident vehicle and the abutment when the accident vehicle is in contact with the guide wheel 40 is increased, and meanwhile, the distance between the accident vehicle and the guide wheel 40 is shortened, so that the guide wheel 40 is favorable for recovering the driving direction of the accident vehicle.
As shown in fig. 2 and 3, further, the support member 10 is configured in a T shape, and the vertical section 11 of the support member 10 is configured with a connection hole 111. The T-shape facilitates attachment of the support member 10 to the abutment.
Further, a rib plate 14 is arranged between the vertical section 11 and the horizontal section 12 of the supporting member 10. The strength of the supporting member 10 is increased, and the service life of the supporting member 10 is prolonged.
As shown in fig. 4, the protection device comprises the above-mentioned guide device, and further comprises a guide fence 50, wherein the guide fence 50 is arranged on the top surface of abutments 60 on two sides of the driving road surface, and the connecting support member 10 is arranged on the side surface of the abutments 60 close to the driving road surface.
When the accident vehicle contacts with the guide wheel 40 and the accident vehicle has a tendency of rolling at the same time, the guide guard bar 50 can play a role of supporting the accident vehicle with the tendency of rolling; the guide fence 50 and guide guard cooperate to provide the accident vehicle with a tendency to move forward.
Further, the guide fence 50 includes a plurality of support columns 51 and friction reducing plates 52, the plurality of support columns 51 are disposed on the top surface of the abutment, and the plurality of support columns 51 are connected by the friction reducing plates 52.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, as any variations, equivalents, or improvements made within the spirit and principles of the present invention are intended to be covered thereby.
