[0002] With the further development of railway transportation and the need to improve vehicle transport efficiency and turnover rate, the problem of deformed pedals on freight cars has become increasingly common due to improper loading and unloading operations. Outward bending of the pedals can easily cause them to exceed the locomotive and rolling stock clearance limits, while inward bending can cause them to come into contact with the coupler lifting rod, resulting in stiffness and affecting train safety. Timely and rapid handling is required. Previous simple tools for handling deformed railway freight car pedals, such as manual adjustment with crowbars and hydraulic tools, all have certain shortcomings. Crowbar adjustments can easily lead to personal injury, while hydraulic tools are bulky and difficult to carry. Further improvement and optimization of tools are needed to increase production efficiency. Summary of the Invention

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] like Figure 1 , Figure 2 As shown, a railway freight car pedal deformation straightening device includes a fixed component and a movable component; the front end of the fixed component is used to connect with the side beam on the upper part of the pedal; the movable component is connected to the rear end of the fixed component, and the movable component includes a connecting component and a moving component. The connecting component is used to connect the deformed pedal; the front end of the moving component is connected to the connecting component, and an external power component acts on the rear end of the moving component, driving the connecting component to push forward or pull backward on the pedal through the moving component, thereby straightening the deformed pedal.

[0039] The following provides a further explanation of the specific structure of the aforementioned fastener.

[0040] like Figure 1 , Figure 2 , Figure 3 As shown, the fastener includes a pair of opposing S-shaped fixing plates 1, a positioning component 2, and a pair of opposing stop plates 3; the through slots 11 at the front ends of the two S-shaped fixing plates 1 are used to hook onto the side beam of the upper part of the pedal; the positioning component 2 is arranged between the two S-shaped fixing plates 1 and is used to fix the two S-shaped fixing plates 1 together with the positioning component 2; the two stop plates 3 are respectively arranged on the outer vertical surface of the two S-shaped fixing plates 1 near the through slots 11, and the stop plates 3 are movably connected to the S-shaped fixing plates 1. When the connecting component moves backward on the pedal, the stop plates 3 are adjusted to contact the side beam of the upper part of the pedal to fix the fastener.

[0041] Further options, such as Figure 1 , Figure 2 , Figure 3 As shown, the positioning component 2 includes a positioning screw and two positioning nuts. The positioning screw is a stepped rod that is thicker in the middle and thinner at both ends. External threads are provided on the radial circumferential surfaces of both ends of the positioning screw. The two ends of the positioning screw are respectively inserted into the through holes opened at the front end of the S-shaped fixing plate 1 on both sides. The positioning screw is positioned by the stepped surface of the positioning screw on the S-shaped fixing plate 1. The two positioning nuts are respectively tightened on the parts of the positioning screw that extend from the S-shaped fixing plate 1 to axially limit the positioning screw.

[0042] Further options, such as Figure 1 , Figure 2 , Figure 3 As shown, the stop plate 3 consists of a vertical plate and a horizontal plate fixed in the middle area of ​​the inner side of the vertical plate. The horizontal plate and the vertical plate form an inverted L-shaped latch for engaging the stop plate 3 in the middle area of ​​the S-shaped fixing plate 1. The vertical plate has a through hole, and the middle area of ​​the S-shaped fixing plate 1 has a threaded hole arranged coaxially with the through hole. The stop plate 3 is connected to the S-shaped fixing plate 1 by the stop plate bolt 4. The position of the stop plate 3 can be adjusted by loosening the stop plate bolt 4, so that the stop plate 3 protrudes or does not protrude from the top surface of the S-shaped fixing plate 1.

[0043] As can be seen from the above, the two through slots 11 on the S-shaped fixing plate 1 are used to hook onto the side beam on the upper part of the deformed vehicle pedal; the slightly thicker middle section of the positioning screw serves to position the two S-shaped fixing plates, and the slightly thinner threaded ends, in conjunction with the positioning nut, can lock the two S-shaped fixing plates 1; the stop plate 3 serves to support the fastener. The operation method for this part is to first loosen the stop plate bolt 4, rotate it to the appropriate position, and then tighten the bolt.

[0044] The following provides a further explanation of the specific structure of the aforementioned moving parts.

[0045] like Figure 1 , Figure 2 , Figure 4As shown, the moving parts use a lead screw and lead nut structure to convert circumferential rotational motion into linear motion, which in turn drives the connecting parts to move forward or backward.

[0046] Further options, such as Figure 1 , Figure 2 , Figure 4 As shown, the lead screw and lead nut structure includes a lead nut 6 and a lead screw 5. The lead nut 6 consists of a ring with a threaded inner surface and two rotating shafts 7 symmetrically arranged on the outer circumference of the ring at a difference of 180 degrees. The two rotating shafts 7 are respectively inserted into the through holes opened at the rear end of the S-shaped fixing plate 1 on both sides. The lead screw 5 is screwed into the ring, and its rear end is connected to an external power component to provide the lead screw 5 with forward or reverse rotational force. The connecting component is movably connected to the front end of the lead screw 5, and the connecting component can rotate circumferentially on the lead screw 5.

[0047] The specific structure of the aforementioned connecting components will be further explained below.

[0048] like Figure 1 , Figure 2 , Figure 4 As shown, the connecting component is a hook 9, which is hinged to a rotating sleeve 8 located at the front end of the lead screw 5. By changing the direction in which the hook 9 is attached to the pedal, the pedal can be pushed forward or pulled backward to straighten the pedal that is bent inward or outward.

[0049] As can be seen from the above, one end of the hook 9 is installed on the rotating sleeve 8, and the other end is hung on the deformed pedal; the rotating sleeve 8 serves to prevent the screw 5 and the hook 9 at the end from moving relative to each other.

[0050] It should be noted that when the pedal bends inward, the hook 9 hooks onto the crossbeam of the pedal in the forward direction. The through slots 11 at the front end of the two S-shaped fixing plates 1 are used to hook onto the side beam of the upper part of the pedal, and the stop plate 3 is adjusted to a vertical position against the side beam. The rotating screw 5 drives the hook 9 to move outward gradually, thereby realizing that the hook 9 straightens the pedal outward.

[0051] When the pedal bends outward, loosen the baffle bolt 4 so that the stop plate 3 does not protrude from the top surface of the S-shaped fixing plate 1. The hook 9 flips and hooks onto the crossbeam of the pedal. The through slots 11 at the front end of the two S-shaped fixing plates 1 are used to hook onto the side beam of the upper part of the pedal. Rotate the screw 5 to drive the hook 9 to move inward gradually, thereby realizing that the hook 9 pushes the pedal inward and straightens it.

[0052] A further proposed solution is a railway freight car pedal deformation straightening device with a fixed connecting member that is symmetrical about the centerline along its length.

[0053] The following describes the railway freight car pedal deformation straightening detection system provided by this utility model. The railway freight car pedal deformation straightening detection system described below can be referred to in correspondence with the railway freight car pedal deformation straightening device described above.

[0054] A railway freight car pedal deformation straightening detection system includes the aforementioned railway freight car pedal deformation straightening device, a power component, and a measuring component; the power component is connected to the moving component and provides rotational force to it; the measuring component is installed on the crossbeam of the deformed pedal and is used as a calibration tool for the operator to check whether the deformed pedal has been straightened.

[0055] In a further embodiment, a medium-sized DC brushless electric wrench is used as the power component to meet the torque required for straightening; a quick-connect nut 10 is fixed at the rear end of the lead screw for use with the socket on the electric wrench, facilitating quick switching between the electric wrench and the lead screw 5.

[0056] A further proposed solution involves using a small digital laser angle gauge as the measuring component for straightening and calibration. The angle gauge is magnetically attached longitudinally to the crossbeam in the middle of the foot pedal, allowing the operator to observe changes in the pedal's angle at any time. When the angle gauge displays 0 degrees, the foot pedal is in a vertical position, and the straightening operation is complete.

[0057] The following describes the working process of the railway freight car pedal deformation straightening detection system.

[0058] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in use, firstly, the two through slots 11 on the upper part of the fixed connector are used to hook onto the side beam of the deformed vehicle pedal. Secondly, an electric wrench is used, connected to the lead screw 5 through the quick-connect nut 10. The rotation of the electric wrench drives the lead screw 5 to rotate. The other end of the lead screw 5 is equipped with a rotating sleeve 8, and the front end of the rotating sleeve 8 is equipped with a hook 9 that can be flipped up and down. During operation, it can form a reliable connection with the crossbeam in the middle of the pedal. During the pedal straightening process, the pedal and the fixed connector will have continuous angle changes. The rotating shaft 7 of the nut 6, the nut 6 and the lead screw 5 can make arc movements on the fixed connector. When the electric wrench rotates forward, it drives the lead screw 5 to rotate forward, and the lead screw 5 pushes forward along the axial direction. When it rotates in reverse, the lead screw 5 pulls backward along the axial direction, thereby straightening the pedal. When the device is in operation, a small digital laser angle gauge is magnetically attached to the crossbeam in the middle of the foot pedal. The operator can observe the angle change of the foot pedal at any time. When the angle gauge shows 0 degrees, the foot pedal is in a vertical state, and the straightening operation is completed.

[0059] In summary, this utility model realizes the function of adjusting the deformation of railway freight car pedals during fault repair within the train fleet; this utility model optimizes the pedal deformation adjustment tool; this utility model is not limited by the type of train, has a simple structure, is easy to carry, and solves the problems of complex, bulky, and difficult-to-carry tools for handling deformation of railway freight car pedals.
