Description

Technical Field

[0001] This utility model relates to the field of locomotive rescue technology, and in particular to a novel wheel lifter. Background Technology

[0002] Wheel lifters are specialized equipment for railway rescue. They are used when the wheelsets of railway locomotives and rolling stock are malfunctioning or have other problems that affect their operation. The wheel lifter lifts the malfunctioning wheelset and uses it as a temporary support to allow the locomotive or rolling stock to resume operation within a limited speed, thus playing an emergency rescue role.

[0003] Conventional wheel lifters require a considerable amount of time to assemble during rescue operations, which prolongs the assembly process and reduces rescue efficiency. In addition, some existing wheel lifters require rescue personnel to climb under the locomotive to assemble the components, which is not only inconvenient to operate but also poses a safety hazard to the rescue personnel.

[0004] Therefore, this application proposes a new type of wheel lifter to solve the problems of low assembly efficiency and safety hazards of the wheel lifter mentioned above. Utility Model Content

[0038] In a preferred embodiment, the two ends of the connecting plate assembly 12 are respectively mounted on the outer side of the corresponding wheel bracket 111; the connecting plate assembly 12 includes two symmetrically arranged side plates 121, and a reinforcing plate 122 is fixedly arranged between the two side plates 121, the reinforcing plate 122 being arranged perpendicular to the side plates 121; symmetrically arranged U-shaped notches 123 are provided on the bottom surface of both ends of the side plates 121, the U-shaped notches 123 being engaged with the interior of the corresponding annular grooves 116, that is, the two ends of a set of connecting plate assemblies 12 are respectively mounted on the mounting shafts 115 of the corresponding wheel brackets 111 through the U-shaped notches 123;

[0039] The length of the reinforcing plate 122 is less than the length of the side plate 121 to avoid affecting the installation of the limiting components;

[0040] A limiting component is provided on one side of the U-shaped notch 123 on the side plate 121 to fix the side plate 121 to the corresponding wheel bracket 111.

[0041] In a preferred embodiment, the limiting component includes a through channel 124 on the side plate 121 located on one side of the U-shaped notch 123, the through channel 124 being arranged parallel to the mounting shaft 115; an annular limiting platform 125 is provided inside the through channel 124, wherein the inner diameter of the annular limiting platform 125 is smaller than the inner diameter of the through channel 124, and the annular limiting platform 125 is coaxially arranged with the through channel 124;

[0047] In a preferred embodiment, the magnetic quick-connect assembly 21 includes a magnetic positioning seat 211 fixedly sleeved on the mounting shaft 115 and located on the circumferential outer side of the corresponding mounting groove 23, and the magnetic positioning seat 211 is provided with a positioning hole 212; a magnetic sleeve 213 is slidably sleeved on the circumferential outer side of the central shaft 22 along its length direction, and a positioning pin 214 is fixedly provided on the magnetic sleeve 213 corresponding to the positioning hole 212, for realizing quick positioning connection between the central shaft 22 and the corresponding side plate 121; the self-positioning step can be completed by the operator reaching out from the outside, and the positioning and installation of the central shaft 22 can be completed without the need for a person to enter the bottom of the locomotive;

[0048] The outer end face of the magnetic positioning seat 211 in the magnetic quick-connect assembly 21 is flush with the end face of the mounting shaft 115 near the mounting groove 23 to avoid interference when assembling with the magnetic sleeve 213.

[0049] In a preferred embodiment, threaded grooves 25 are provided on the two end faces of the central shaft 22 corresponding to the threaded channel 24, and the threaded grooves 25 are coaxially arranged with the central shaft 22; bolts 26 are provided inside the threaded channel 24 and the corresponding threaded grooves 25 to connect and fix the central shaft 22 and the mounting shaft 115.

[0050] One method is to use an electric screwdriver to tighten the bolt 26, which improves efficiency.

[0051] In a preferred embodiment, a limiting groove 28 located on the bottom of the mounting groove 23 and on the circumferential outer side of the threaded channel 24 is further provided. A limiting protrusion 27 is provided on the end face of the central shaft 22 on the circumferential outer side of the threaded groove 25 corresponding to the limiting groove 28. When the positioning pin 214 and the corresponding positioning hole 212 are in the assembled state, the limiting protrusion 27 is engaged with the interior of the corresponding limiting groove 28.

[0052] The working principle of this novel invention is as follows:

[0053] In use, two running wheels 11 are respectively installed at both ends of a connecting plate assembly 12. Specifically, the ends of two side plates in a set of connecting plate assemblies 12 are respectively mounted on the two ends of the mounting shaft 115 of the corresponding running wheels 11, and the U-shaped notch 123 on the side plate 121 is mounted on the annular groove 116 on the mounting shaft 115 to prevent the side plate 121 from shifting in the left and right directions on the mounting shaft 115. As the side plate 121 moves downward along the side upright plate 1111 on the wheel bracket 111, the limiting pin 127 slides towards the pull ring 129. At this time, the spring 130 is stretched. When the limiting pin 127 moves to the position of the insertion groove 126 on the side upright plate 1111 of the wheel bracket 111, under the action of the spring 130, the limiting pin 127 is inserted into the interior of the corresponding insertion groove 126, completing the installation between the side plate 121 and the wheel bracket 111.

[0054] After both sets of connecting plate assemblies 12 are installed, the central shaft 22 is quickly connected to the inside of the mounting groove 23 using the magnetic quick-connect assembly 21. Specifically, when the positioning pin 214 on the magnetic sleeve 213 corresponds to the positioning hole 212 on the magnetic positioning seat 211, the limiting protrusion 27 on one end of the central shaft 22 inserted into the mounting groove 23 is inserted into the corresponding limiting groove 28 to limit the installation position of the central shaft 22. Then, the bolt 26 is screwed into the corresponding threaded channel 24 until it is screwed into the corresponding threaded groove 25 of the central shaft 22, connecting and fixing the central shaft 22 to the corresponding mounting shaft 115, thus completing the installation of the central shaft 22.

[0055] The entire installation process is simple, convenient, and efficient, thus improving the efficiency of rescue operations.
