Description

A self-centering anti-climbing and anti-deviation device for rail vehicles

technical field

The invention belongs to the technical field of passive safety of rail transit vehicles, in particular to the passive safety technology of train ends.

Background technique

In order to ensure that rail transit vehicles do not climb during the train-to-train collision, a structure that limits the vertical displacement of the train will be installed, which is called an anti-climbing structure. Once the rail transit vehicle climbs, it is likely to derail or even roll over, which will have an adverse impact on the drivers and passengers, the structure of the car body and the railway facilities. At present, the anti-climbing structure of rail transit vehicles is generally integrated with the energy-absorbing structure, which is called an energy-absorbing anti-climbing device. Engagement to limit the vertical displacement of the end of the vehicle to achieve the purpose of anti-climbing. Although this structure can effectively limit the vertical movement of the vehicle end, there are still some deficiencies, two of which are: the inability to limit the lateral displacement of the vehicle end, that is, deflection prevention. In fact, the lateral displacement of the vehicle during the collision Movement also has a great impact on derailment and rollover. On the other hand, if the lateral displacement is too large, the anti-climbing teeth may be out of contact, and the anti-climbing function will be lost, resulting in the inability of the energy-absorbing structure to function; It must be vertically staggered, and may be horizontally staggered, which may lead to partial load of the rear energy-absorbing structure, which has a great impact on the stable energy absorption of the energy-absorbing structure. In view of the deficiencies of the current tooth-shaped anti-climbing structure, the present invention proposes a "rail vehicle self-centering anti-climbing and anti-deviation device", which can effectively make up for the deficiency of the tooth-shaped anti-climbing structure.

Contents of the invention

The object of the present invention is to provide a self-alignment anti-climbing and anti-deviation device for rail vehicles, which can effectively solve the deficiencies of existing anti-climbing structures and achieve the problems of anti-climbing, anti-deviation and automatic centering.

In order to solve the technical problem, the present invention adopts the following technical solutions: a self-centering anti-climbing and anti-deviation device for rail vehicles, including two sets of separate male and female body components, the male body components are dome cones with square mounting plates, round The dome of the top conical body is equipped with a reinforced cylinder, and the whole is a casting structure; the four corners of the mounting plate are provided with bolt holes; the female body member is an inner cone with a square mounting plate, and there are reinforcements around the inner cone surface of the inner cone. The ring column is a casting structure as a whole; the bottom contour of the inner cone surface is the same as the outer contour of the dome, and the depth of the inner cone surface is consistent with the height of the cone body of the dome; bolt holes are provided at the four corners of the mounting plate.

The contour of the inner cone surface of the inner cone cylinder is the same as the dome outer contour of the dome cone body, and the depth of the inner cone surface is consistent with the height of the dome cone body.

The male and female components are arranged separately on the same vehicle body, that is, the dome cone and the inner cone are arranged separately at the left and right ends of the same vehicle body or at the front and rear of the vehicle body.

The male and female components are alternately arranged on different vehicle bodies, that is, the dome cone and the inner cone are arranged correspondingly at the left and right ends of different vehicle bodies or at the front and rear of the vehicle body.

Both the dome cone and the inner cone are integrally cast hollow structures.

The dome is a hemispherical structure.

In order to ensure the realization of the self-centering anti-climbing and anti-deviation structure function of the rail vehicle, the following principles should be followed during installation and use:

The end of the car body where the self-aligning anti-climbing and anti-deviation structure of the rail vehicle is installed is called "front", the other end is "rear", the inner cone is installed on the left side, and the dome cone is installed on the right side. Each end of each end is installed in the above arrangement, and it should be ensured that the center distance between the inner cone and the installation dome cone is the same after the installation is completed; another equivalent installation method can also be used, that is, to install the rail vehicle self-aligning The end of the car body of the middle anti-climbing and anti-deviation structure is "front", and the other end is "rear". The dome cone is installed on the left side, and the inner cone is installed on the right side. Each end of each vehicle adopts the above arrangement It should be installed, and it should be ensured that the center distance between the inner cone and the installation dome cone is the same after the installation is completed; other methods that can ensure the smooth engagement of the rail vehicle self-alignment anti-climbing and anti-deflection structure at the end of the vehicle can also be used.

When two rail transit vehicles collide, there may be a relative position deviation between the corresponding dome cone and the inner cone; when the relative position deviation is within the maximum circular section of the inner cone, due to the inner cone and the circle There is a taper at the top, and the dome will automatically slide into the inner cone surface, so that the dome cone and the inner cone are automatically centered, and the vertical and lateral relative displacement of the car end can be restrained. That is, it can effectively limit the vertical and lateral displacement of the end of the rail transit vehicle when a collision occurs, and can effectively ensure the automatic centering of the axis of the energy-absorbing structure at the rear end, thereby achieving stable energy absorption.

Compared with the existing structure and technology, the present invention has the beneficial effects that: during the collision process, the vertical and lateral displacement of the end of the rail transit vehicle can be effectively limited, the climbing and yaw can be avoided, and the anti-climbing structure can not be out of contact ;It can effectively guarantee the automatic centering of the axis of the energy-absorbing structure at the rear end, avoid the partial load failure of the energy-absorbing structure, and then realize the stable energy-absorbing of the energy-absorbing structure; it can directly and effectively realize the meshing, simple and reliable.

The dome cone body 1 is an integral casting structure, including a reinforced cylinder 8 inside the dome 7 and a square mounting plate 6 at the bottom; Ensure smoother meshing and optimize structural stress distribution; Bolt holes 9 are opened at the four corners of the mounting plate 6, which can be connected to the energy-absorbing structure 3 at the end of the vehicle through bolts, and then connected to A-car 4 and B-car 5 through the energy-absorbing structure 3. The inner cone 2 is an integral casting structure, including an inner cone 11, a reinforced circular column 12, and a square mounting plate 10; the bottom of the inner cone 11 has a spherical rounding, which can be in close contact with the dome 7, and the edge of the inner cone is also inverted. Round, which is conducive to smooth meshing and can optimize the structural stress distribution; bolt holes 13 are opened at the four corners of the mounting plate, which can be connected to the energy-absorbing structure 3 of the vehicle end through bolts, and then connected to the vehicle body A4 and vehicle body B5 through the energy-absorbing structure 3 .

The self-centering anti-climbing and anti-deviation structure of the rail vehicle requires two structures to be used in one-to-one cooperation, that is, the domed cone 1 and the inner cone 2 are used in conjunction.

The inner contour of the inner tapered surface 11 is exactly the same as the outer contour of the dome 7, and the depth of the inner tapered surface 11 and the height of the dome 7 should also be exactly the same.

In order to ensure the accurate realization of the self-alignment anti-climbing and anti-deviation structure function of the rail vehicle, taking the rail transit vehicle (A car 4, B car 5) with cab structures at both ends as an example, the following principles should be followed during installation and use :

Take the end of the rail vehicle body that is being installed with the self-alignment anti-climbing and anti-deviation structure as "front", and the other end as "rear", the inner cone 2 is installed on the left side, and the dome cone 1 is installed on the right side. Each end of a vehicle is installed in the above arrangement, and it should be ensured that the center distance between the inner cone 2 and the installation dome cone 1 is the same after the installation is completed.

Further, another equivalent installation method can also be used, that is, the end of the car body that is installing the rail vehicle self-centering anti-climbing and anti-deviation structure is "front", the other end is "rear", and the left side is The dome cone 1 is installed, and the inner cone 2 is installed on the right side. Each end of each vehicle is installed in the above arrangement, and it should be ensured that the center distance between the inner cone 2 and the installation dome cone 1 is the same after the installation is completed.

Furthermore, other methods that can ensure the smooth engagement of the rail vehicle self-centering anti-climbing and anti-deflection structure at the end of the car body, that is, to ensure that each end of each vehicle can smoothly realize the internal The meshing relationship between the cone 2 and the dome cone 1; of course, for smooth and convenient use and installation, the above-mentioned installation method should be realized under the premise of ensuring that each end of each vehicle is in the same arrangement.

When two rail transit vehicles collide, under the influence of the vehicle's own structural characteristics and the external operating environment, the corresponding dome cone 1 and inner cone 2 may have relative position deviations, including vertical and lateral displacements The deviation also includes the deflection angle of the axis; when the relative position deviation of the two is within the maximum circular cross-section range of the inner cone surface 11, due to the taper of the inner cone surface 11 and the dome 7, the dome 7 will collide in the longitudinal direction. Under the action of the force, it automatically slides into the inner cone surface 11 along the inner contour of the inner cone surface 11; since the inner contour of the inner cone surface 11 is exactly the same as the outer contour of the dome 7, under the continued action of the longitudinal impact force, the convex dome 7 It will completely fit with the concave inner cone surface 11; thus, the axes of the two are collinear, which realizes the automatic centering of the dome cone 1 and the inner cone 2, and can restrain the vertical and lateral relative displacement of the car end.
