[0030] Example
[0031] Reference Figures 1-5 This utility model provides a bogie hoisting straightener, including an upper crossarm 100, a rotating sleeve 500, and a lower positioning support 200; the lower end face of the upper crossarm 100 is provided with a lower threaded post 300, the upper end face of the lower positioning support 200 is provided with an upper threaded post 400, and the upper threaded post 400 is screwed from the upper end of the rotating sleeve 500 into the rotating sleeve 500, and the lower threaded post 300 is screwed from the lower end of the rotating sleeve 500 into the rotating sleeve 500.
[0032] The distance between the upper crossarm 100 and the lower positioning bracket 200 is adjusted by rotating the rotating sleeve 500; the upper crossarm 100 is used to connect with the bolster, and the lower positioning bracket 200 is used to connect with the bogie.
[0033] In some embodiments, the upper crossbeam 100 of the bogie hoisting straightener is provided with a lower threaded post 300, and the lower positioning bracket 200 is provided with an upper threaded post 400, and the threads on the upper threaded post 400 and the lower threaded post 300 are opposite in direction; the threads inside the rotating sleeve 500 are divided into two parts, that is, the rotating sleeve 500 can be screwed to the upper threaded post 400 and the lower threaded post 300 respectively;
[0034] When the rotating sleeve 500 is rotated, the rotating sleeve 500 can make the distance between the upper thread 400 column and the lower thread 300 column smaller or larger, and also make the distance between the upper crossarm 100 and the lower positioning bracket 200 smaller or larger; in this way, the bogie hoisting straightener can fix the bogie and the bolster together, and can be separated again later.
[0035] An installation hole is provided on the bolster. After the upper crossarm 100 enters the installation hole, the direction of the upper crossarm 100 is rotated so that the upper crossarm 100 cannot be disengaged from the installation hole. Generally, the installation hole is a non-circular hole.
[0036] The lower positioning bracket 200 is hung on the bogie. When the rotating sleeve 500 is rotated, the distance between the upper crossarm 100 and the lower positioning bracket 200 is reduced, thus realizing the installation of the bogie hoisting straightener on the bogie and the bolster. The bolster is fixedly connected to the car body. When the car body is hoisted, the bolster causes the bogie to move simultaneously.
[0037] Since the bogie hoisting straightener can be installed outside the railway freight car, it does not require manual entry into the underside of the freight car for installation, which improves installation efficiency and makes it easy to remove the bogie hoisting straightener.
[0038] In an optional embodiment, the upper thread 400 post is provided on one side of the lower positioning support 200 in a first direction;
[0039] The first direction is the length direction of the lower positioning support 200.
[0040] Reference Figure 2 and Figure 5 In an optional embodiment, at least one set of positioning plates 800 is provided on the upper surface of the lower positioning support 200, each set of positioning plates 800 includes two positioning plates 800, and the two positioning plates 800 are disposed on both sides of the upper surface of the lower positioning support 200 in a first direction.
[0041] In some embodiments, an upper threaded post 400 is provided on one side of the lower positioning support 200. In order to avoid affecting the lower positioning support 200 being hung on the bogie, the upper threaded post 400 is provided on one side of the lower positioning support 200 in a first direction.
[0042] To prevent the lower positioning support 200 from detaching from the bogie, at least one set of positioning plates 800 is provided on the lower positioning support 200, with the two positioning plates 800 positioned on both sides in the first direction; the two positioning plates 800 cooperate to clamp the bogie, thus preventing the lower positioning support 200 from detaching from the bogie during hoisting.
[0043] Two positioning plates 800 extending along the first direction can be set on the upper surface of the lower positioning support 200. The length of the positioning plates 800 is equal to the length of the lower positioning support 200. In order to reduce the weight of the entire bogie hoisting straightener, two sets of positioning plates 800 are set on the lower positioning support 200. A set of positioning plates 800 is set at each end of the lower positioning support 200 in the first direction. This ensures that the lower positioning support 200 is firmly connected to the bogie and reduces the weight of the entire bogie hoisting straightener. This allows a single person to easily operate the bogie hoisting straightener and improves hoisting efficiency.
[0044] In an optional embodiment, an upper reinforcing rib 700 is provided on the upper end surface of the upper crossbeam 100.
[0045] In an optional embodiment, a lower reinforcing rib is provided on the lower end surface of the lower positioning support 200.
[0046] Because the bogie of a railcar has a large mass, the upper crossarm 100 and the lower positioning support 200 need to have higher strength. An upper reinforcing rib 700 is provided on the upper end face of the upper crossarm 100. The lower end face of the upper crossarm 100 abuts against the bolster, and the lower end face of the upper crossarm 100 remains flat. That is, the upper reinforcing rib 700 is provided on the upper end face of the upper crossarm 100 to strengthen the strength of the upper crossarm 100, so that the upper crossarm 100 is not easily deformed.
[0047] A lower reinforcing rib is provided on the lower end face of the lower positioning support 200 to increase the strength of the lower positioning support 200. In this way, while ensuring the strength of the upper crossarm 100 and the lower positioning support 200, the weight of the overall bogie hoisting straightener is reduced, making it convenient for a single operator to operate.
[0048] In an optional embodiment, the upper crossbeam 100 is provided with a weight-reducing hole 600.
[0049] In an optional embodiment, the lower positioning support 200 is provided with a weight reduction hole 600.
[0050] To further reduce the weight of the bogie hoisting straightener, multiple weight-reducing holes 600 are provided on the upper crossarm 100 and the lower positioning support 200. This effectively reduces the weight of the bogie hoisting straightener and makes it easier for operators to operate it.
[0051] In an optional embodiment, the threads of the upper thread 400 post and the lower thread 300 post are opposite.
[0052] Reference Figure 5 In an optional embodiment, the rotating sleeve 500 is provided with at least one mounting hole 900.
[0053] In an optional embodiment, the rotating sleeve 500 is provided with a plurality of mounting holes 900, and the plurality of mounting holes 900 are evenly arranged along the circumference of the rotating sleeve 500.
[0054] In some embodiments, the threads of the upper thread 400 and the lower thread 300 are in opposite directions, and the rotating sleeve 500 has threads that match the upper thread 400 and threads that match the lower thread 300; when the rotating sleeve 500 rotates, the distance between the upper thread 400 and the lower thread 300 increases or decreases.
[0055] To facilitate the rotation of the rotating sleeve 500, an assembly hole 900 is provided on the rotating sleeve 500; when the rotating sleeve 500 is not easy to rotate, the handle is inserted into the assembly hole 900 to drive the handle to rotate the rotating sleeve 500.
[0056] Since the rotating sleeve 500 is adjacent to the bogie and bolster, multiple mounting holes 900 are provided on the rotating sleeve 500; when the handle cannot be rotated, the handle is inserted into the appropriate mounting hole 900, and the rotating sleeve 500 can continue to rotate by operating the handle.
[0057] The bogie crane straightener provided by this utility model has its upper crossarm 100 inserted into the bolster and rotated, and its lower positioning bracket 200 hung on the bogie. By rotating the rotating sleeve 500, the distance between the upper crossarm 100 and the lower positioning bracket 200 is reduced, thus fixing the bogie and the car together. When hoisting the car, the bogie follows the car. Moreover, when installing the bogie crane straightener, it is not necessary to crawl under the car; the bogie crane straightener can be installed on the bolster and bogie simply by looking at the side of the car, thus connecting the bogie and the car and improving rescue efficiency.
[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
