Description

Technical Field

[0001] This application relates to the field of railway auxiliary equipment technology, and in particular to a top support mechanism and a recovery and rescue device. Background Technology

[0002] Railway accidents disrupt the normal order of railway transportation. In such cases, it is necessary to install a re-railing rescue device under the coupler of the locomotive or rolling stock to lift and laterally move the derailed locomotive or rolling stock to re-rail it.

[0003] During the lifting process, the lifting and rescue device includes a hydraulic cylinder and a support mechanism located above the hydraulic cylinder. The side of the support mechanism away from the hydraulic cylinder abuts against the lower part of the coupler of the locomotive or vehicle. The hydraulic cylinder acts on the support mechanism to drive the entire locomotive or vehicle to move, thereby lifting the locomotive or vehicle.

[0004] However, the current support mechanism has poor stability during use and is easily squeezed out between the coupler and the hydraulic cylinder, which can lead to the failure of locomotive or vehicle to restart. Utility Model Content

[0005] Therefore, it is necessary to provide a top support mechanism and a re-starting and rescue device to address the problem that the current top support mechanism has poor stability during use and is easily squeezed out between the coupler and the hydraulic cylinder, which leads to the failure of locomotive or vehicle re-starting.

[0006] A top support mechanism, the top support mechanism comprising a base and a support column, wherein:

[0007] The base has a first side and a second side facing each other. The first side is located at the lifting output end of the lifting drive member, and the projection of the first side on a plane can extend beyond the lifting output end. The second side abuts against the lifting iron of the car coupler.

[0008] The support column is disposed on the second side, and the support column also has a first end away from the second side, the first end abutting against the body of the coupler.

[0009] The aforementioned support mechanism, by setting the second side of the base to abut against the lifting iron of the coupler and the first end of the support column to abut against the main body of the coupler, increases the contact points between the support mechanism and the coupler, making it easier for the support mechanism to transmit the lifting driving force of the lifting drive to the coupler, so as to realize the lifting and repositioning of the coupler; by setting the first side to be configured so that its projection on a plane can exceed the lifting output end, it is ensured that the support mechanism can maintain a stable center of gravity when it is lifted and lowered under the drive of the lifting drive, and the support mechanism is not easily squeezed out between the coupler and the hydraulic cylinder, so that the support mechanism can stably drive the coupler to lift and lower, thereby ensuring the normal lifting and repositioning of the locomotive or vehicle.

[0010] In one embodiment, the support column is integrally formed with the base, and the support column is perpendicular to the base.

[0011] In one embodiment, the support column has a weight-reducing hole, which opens at the first end. The depth of the weight-reducing hole extends along a first direction, and the depth of the weight-reducing hole does not exceed the height of the support column along the first direction.

[0012] In one embodiment, the orthographic projection of the two side walls of the support column, which are arranged opposite each other along the second direction, in the base lies on the outline of the base.

[0013] In one embodiment, the top support mechanism further includes a top support reinforcing rib, the two ends of which are respectively connected to the support column and the base.

[0014] In one embodiment, the number of the top support reinforcing ribs is multiple, and the multiple top support reinforcing ribs are distributed at equal intervals.

[0015] In one embodiment, the top support mechanism further includes at least one handle disposed on the outer wall of the support column.

[0029] See Figure 1 and Figure 2 As shown, Figure 1 A schematic diagram of the top support mechanism 10 in one embodiment of this application is shown. Figure 2 This diagram illustrates a structural schematic of the top support mechanism 10 according to another perspective of one embodiment of the present application. The top support mechanism 10 provided in one embodiment of the present application is used to transmit lifting force to the coupler. The coupler includes a main body and a lifting iron perpendicular to the main body, the lifting iron being located below the main body.

[0030] The top support mechanism 10 includes a base 100 and a support column 200. The base 100 has a first side 110 and a second side 120 facing each other. The first side 110 is located at the lifting output end of the lifting drive member, and the projection of the first side 110 on a plane can extend beyond the lifting output end. Specifically, the orthographic projection of the first side 110 on the lifting output end extends beyond the lifting output end, that is, the size of the first side 110 is larger than the lifting output end. The second side 120 abuts against the lifting iron of the coupler. The support column 200 is located on the second side 120, and the support column 200 also has a first end away from the second side 120, which abuts against the main body of the coupler.

[0031] More specifically, the orthographic projection of the first side 110 at the lifting output end is located outside the lifting output end profile. In order to increase the contact area between the first side 110 and the lifting drive component in the lifting support mechanism 10, the lifting drive component is usually a hydraulic cylinder. The size of the first side 110 is larger than the cylinder diameter of the last stage of the hydraulic cylinder, so that the center of gravity of the lifting support mechanism 10 can be stabilized when it is lifted and lowered by the hydraulic cylinder, ensuring that the lifting support mechanism 10 stably drives the coupler to lift and lower, and the lifting support mechanism 10 is not easily squeezed out between the coupler and the hydraulic cylinder, thereby ensuring the normal start-up and recovery of the locomotive or vehicle.

[0032] It should be noted that, for the convenience of large-scale production, the base 100 can be a rectangular plate, but is not limited to a rectangular plate; it can also be a circular plate, a polygonal plate, or any other geometric plate. For ease of production, this application preferably uses a rectangular plate for the base 100. The shape of the support column 200 is preferably a cuboid, but is not limited to a cuboid; it can also be a frustum of a cone, a cylinder, or other structures. With the above settings, and given the simple overall structure and convenient production of the top support mechanism 10 of this application, it can effectively improve production time and save costs.

[0033] To ensure the structural strength of the top support mechanism 10, in a preferred embodiment, the support column 200 is integrally formed with the base 100, and the support column 200 is perpendicular to the base 100. To achieve lightweight production without affecting the structural strength of the top support mechanism 10, in a preferred embodiment, the support column 200 has a weight-reducing hole 210. The weight-reducing hole 210 opens at a first end, and its opening depth extends along a first direction a, and the opening depth of the weight-reducing hole 210 does not exceed the height of the support column 200 along the first direction a.

[0034] In specific settings, the shape of the weight-reducing hole 210 is the same as that of the support column 200, both being cuboids. It should be noted that the shape of the weight-reducing hole 210 is limited to cuboids, but can also be any geometric shape such as a rhombus, cylindrical plate, or polygon.

[0035] To enhance the structural strength between the support column 200 and the base 100, in a preferred embodiment, the orthographic projection of the two side walls of the support column 200, which are directly opposite each other along the second direction b, onto the outline of the base 100, with the second direction b perpendicular to the first direction a. Specifically, the orthographic projection of the two side walls of the support column 200, which are directly opposite each other along the third direction c, onto the outline of the base 100, with the support column 200 specifically positioned at 1 / 3 of the distance along the third direction c of the base 100, where the third direction c, the second direction b, and the first direction a are mutually perpendicular. It should also be emphasized that the support column 200 can also be positioned at 1 / 2 of the distance along the third direction c of the base 100, depending on the type of coupler, so that the support column 200 and the base 100 can correspondingly abut against the main body and lifting iron in the coupler. In specific manufacturing, the dimensions of the support column 200 and the base are adjusted accordingly based on the coupler type and the size of the hydraulic cylinder.

[0036] To further enhance the structural strength between the support column 200 and the base 100, in a preferred embodiment, the top support mechanism 10 further includes a top support reinforcing rib 500, with both ends of the top support reinforcing rib 500 connected to the support column 200 and the base 100, respectively. It should be noted that the orthographic projection of the two side walls of the support column 200, which are directly opposite each other along the third direction c, is located within the outline of the base 100. That is, a receiving space 300 is formed between the support column 200 and the base 100, and the top support reinforcing rib 500 is located within the receiving space 300.

[0037] In the specific configuration, multiple top support reinforcing ribs 500 are provided, evenly spaced and parallel to each other. Preferably, each top support reinforcing rib 500 has a triangular structure, meaning that two adjacent sides of the triangular rib 500 are connected to the support column 200 and the base 100, respectively. This configuration enhances the stability of the top support mechanism 10 and increases its structural strength. To prevent accidental injury to workers during installation, an arc-shaped clearance groove 510 is provided on the side of the top support reinforcing rib 500 facing away from the support column 200.

[0038] To facilitate the handling of the top support mechanism 10, in a preferred embodiment, the top support mechanism 10 further includes at least one handle 400, which is disposed on the outer wall of the support column 200. In a specific configuration, there may be two handles 400, which are disposed on the two side walls of the support column 200 distributed along the second direction b, so as to prevent the handles 400 from affecting the distribution of the top support reinforcing ribs 500.

[0039] To facilitate the design of the handle 400 structure, specifically, the handle 400 includes a first rod 410, a second rod 420, and a third rod 430. The first rod 410 and the second rod 420 are spaced apart along a first direction a on the support column 200, and the third rod 430 connects the first rod 410 and the second rod 420. In a specific configuration, the first rod 410 and the second rod 420 are respectively located at the top and bottom of the side wall of the support column 200, so that a large receiving cavity 440 is formed between the first rod 410 and the second rod 420, making it convenient for workers to quickly grab or release the handle 400 through the receiving cavity 440.

[0040] To prevent workers from being scratched when moving the top support mechanism 10 using the handle 400, more specifically, a first arc-shaped chamfer 450 is provided between the first rod 410 and the second rod 420, and a second arc-shaped chamfer 460 is provided between the second rod 420 and the third rod 430, thus preventing workers from being scratched when holding the handle 400.

[0041] To ensure both high pressure resistance and lightweight design of the top support mechanism 10, a preferred embodiment uses an alloy material for the top support mechanism 10. By using an alloy material, the traditional cast iron and cast steel materials used in top support mechanisms 10 are eliminated, achieving both light weight and high pressure resistance. Specifically, the alloy material can be an iron-based alloy, aluminum alloy, copper alloy, or other similar alloys.

[0042] This application also provides a resuscitation and rescue device, which includes a lifting drive and a support mechanism 10 as described in any of the above embodiments, wherein the lifting output end of the lifting drive is connected to the support mechanism 10.

[0043] The aforementioned re-lifting and rescue device includes a top support mechanism 10. By setting the second side 120 of the base 100 of the top support mechanism 10 to abut against the lifting iron of the coupler, and the first end of the support column 200 to abut against the main body of the coupler, the contact points between the top support mechanism 10 and the coupler are increased, which makes it easier for the top support mechanism 10 to transmit the lifting driving force of the lifting drive component to the coupler, so as to realize the re-lifting of the coupler. By setting the first side 110 to be configured so that its projection on a plane can exceed the lifting output end, it is ensured that the top support mechanism 10 can also maintain a stable center of gravity when it is lifted and lowered by the lifting drive component. The top support mechanism 10 is not easily squeezed out between the coupler and the hydraulic cylinder, so that the top support mechanism 10 can stably drive the coupler to lift and lower, thereby ensuring the normal re-lifting of the locomotive or vehicle.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
