Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of railway locomotive maintenance equipment, in particular to a portable railway locomotive hook height adjusting device. Background Art
[0002] A locomotive is a self-propelled vehicle that pulls or pushes railway vehicles and does not carry any commercial loads. It is commonly known as a locomotive. Calculated by the amount of fuel consumed per ton-kilometer transported, a locomotive is the land transportation tool with the lowest energy consumption. Locomotives are generally driven directly or through transmission devices by power machinery such as steam engines, diesel engines, gas turbines, and traction motors. The power machinery causes the locomotive's driving wheels to generate torque, and at the same time the road gives the driving wheels an equal and opposite reaction force. The sum of the reaction forces of each driving wheel is called the locomotive traction force. This traction force is a tangential external force generated by the force acting on the driving wheel, so it is also called wheel circumference traction force.
[0003] During the use of locomotives, the height of the hook may be reduced due to wear and deformation of certain parts. If the height difference between the two connected hooks is too large, the lower hook ear of the high hook and the upper hook ear of the low hook will be subjected to great force. Due to vibration, there is a risk of unhooking, so the locomotive needs to be inspected. When adjusting the height of the hook, it is necessary to use the hook suspended by the overhead crane in a specific workshop to adjust the height of the hook. This is not only difficult to operate and relies on special equipment and sites, but also poses a risk of personal injury. In order to overcome the difficulties in operation and the shortcomings of relying on special equipment and sites, a tool and fixture with a simple and reasonable structure and safe and convenient operation is needed.

[0019] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0020] As Figure 1 , Figure 2 , Figure 3 shown, the present utility model provides a portable height adjustment device for railway locomotive couplers, which includes a triangular steel frame 10, a clamp 20, a placement platform 30 and a jack 40. The clamp 20 is installed at the bottom of the triangular steel frame 10 for fixing the triangular steel frame 10 on the rail. The placement platform 30 is installed at the top of the triangular steel frame 10, and the jack 40 is installed on the placement platform 30. The jack 40 is used to lift the locomotive.
[0021] The triangular steel frame 10 is made of stainless steel and formed into a triangle by welding as the main structure of the device. To avoid stress concentration, the triangular steel frame 10 is chamfered.
[0022] Through the settings of the triangular steel frame 10, the clamp 20, the placement platform 30 and the jack 40, the clamp 20 is clamped on the rail, and the clamp 20 prevents the triangular steel frame 10 from moving to both sides. The placement platform 30 plays a role in bearing the jack 40. The locomotive can be lifted by the jack 40, that is, the coupler can be supported, so as to complete the work of adjusting the coupler height. The portable height adjustment device for railway locomotive couplers is convenient to operate, has strong practicability, can be placed in various sites, and avoids shaking when hanging a hook on a crane, improving safety.
[0023] In this embodiment, specifically, the jack 40 is fixedly installed at the center of the top of the "冂"-shaped platform. The triangular steel frame 10 is an equilateral triangular frame.
[0024] The clamp 20 includes a first "L"-shaped angle iron 21 and a second "L"-shaped angle iron 22. The first "L"-shaped angle iron 21 and the second "L"-shaped angle iron 22 are symmetrically arranged at the bottom of the triangular steel frame 10. In this embodiment, the first "L"-shaped angle iron 21 and the second "L"-shaped angle iron 22 are fixed to the bottom of the triangular steel frame 10. Reinforcement blocks are provided between the first "L"-shaped angle iron 21 and the second "L"-shaped angle iron 22 and the triangular steel frame 10.
[0025] The horizontal plane of the first "L"-shaped angle iron 21 and the second "L"-shaped angle iron 22 on both sides of the bottom of the triangular steel frame 10 can support the device, ensuring stability and preventing the device from tilting to both sides. The distance between the vertical planes of the first "L"-shaped angle iron 21 and the second "L"-shaped angle iron 22 is the standard gauge, ensuring that the device can be just placed on the railway track without lateral displacement.
[0026] In this embodiment, specifically, the placing platform 30 is a "冂"-shaped platform, and the "冂"-shaped platform is fixedly installed on the top of the triangular steel frame 10, and the jack 40 is fixed on the top of the "冂"-shaped platform.
[0027] A "冂"-shaped platform is welded on the triangular steel frame 10. The inside of the "冂"-shaped platform is a hollow cavity, and the "冂"-shaped platform serves as a platform for carrying the jack 40.
[0028] In this embodiment, further, the center of the top of the inner cavity of the "冂"-shaped platform is fixedly connected to the triangular steel frame 10, and both ends of the bottom of the "冂"-shaped platform are respectively fixedly connected to the triangular steel frame 10.
[0029] The portable railway locomotive coupler height adjustment device further includes a limit clamp 50 and a support vertical beam 60. The limit clamp 50 is fixed to the lifting end of the jack 40. Specifically, the limit clamp 50 is set as a "凵"-shape to clamp the locomotive. The support vertical beam 60 is fixed inside the triangular steel frame 10 to stabilize the triangular steel frame 10.
[0030] The jack 40 is welded on the "冂"-shaped platform, and a "凵"-shaped limit clamp 50 is welded above the jack 40. The "凵"-shaped limit clamp 50 is used to bear the gravity of the coupler.
[0031] To improve the overall strength, three support vertical beams 60 are welded in the triangular steel frame 10 structure, and the inside of the support vertical beam 60 is a hollow cavity.
[0032] When in use, first lower the jack 40 to the lowest position; then place the first "L"-shaped angle iron 21 and the second "L"-shaped angle iron 22 of the device on the railway track, making the inner planes of the first "L"-shaped angle iron 21 and the second "L"-shaped angle iron 22 closely adhere to the surface of the rail to prevent the device from moving to both sides; then adjust the position of the device along the railway track back and forth so that the "凵"-shaped limit clamp 50 above the jack 40 is located at the protruding part below the coupler body; finally, use a wrench to adjust the height of the jack 40, and the coupler can be supported, thus completing the coupler height adjustment work.
