[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 6 The utility model discloses a wheelset positioning device applied to urban rail transit electric passenger cars, including a crossbeam 3, the crossbeam 3 is made of aluminum alloy, a scale line 5 is provided on one side of the crossbeam 3, and a limit slot 4 is provided in the crossbeam 3, a level 6 is installed at the middle position of the upper surface of the crossbeam 3, through the setting of the level 6, the horizontal state of the crossbeam 3 can be detected, thereby improving the accuracy of measuring and positioning the center distance of the wheelset, in addition, a limit slider 10 is slidably installed inside the limit slot 4, and a positioning plate 15 is fixed on the limit slider 10, and the movement of the positioning plate 15 is realized by the sliding connection between the limit slider 10 and the limit slot 4, and the sliding distance of the limit slider 10 can be measured under the cooperation between the scale line 5 and the positioning plate 15.

[0024] In addition, the wheelset positioning device for urban rail transit electric passenger cars provided in this embodiment also includes a support assembly, with two support assemblies in total, one of which is installed at one end of the crossbeam 3, and the other is installed on the outside of the limiting slider 10. By detecting the distance between the two support assemblies, the distance between two adjacent wheelsets can be accurately detected, which is beneficial to the positioning of the wheelset.

[0025] The above-mentioned support assembly includes a base 1, a support seat 2 is fixed on the upper surface of the base 1, a column 7 is provided on the support seat 2, a lifting assembly is provided between the column 7 and the support seat 2, and a positioning pin 8 is movably installed on the side of the column 7 away from the crossbeam 3, and a fixing plate 9 fixedly connected to the wheelset shaft is installed at the other end of the positioning pin 8. The fixing plate 9 is preferably an inner circle fixing part for connecting the wheelset shaft and the positioning pin 8, so that the distance between the two positioning pins 8 is the center distance of the wheelset, thereby realizing the positioning of adjacent wheelsets.

[0026] like Figure 4-Figure 6 As shown, the lifting assembly includes a transmission bin 19 opened inside the column 7, a driving shaft 20 is rotatably installed inside the transmission bin 19, a first bevel gear 21 is installed on the driving shaft 20, and the other end of the driving shaft 20 passes through the transmission bin 19 and is installed with a knob, a threaded sleeve 22 is axially rotatably installed inside the column 7, a second bevel gear 23 meshing with the first bevel gear 21 is installed on the upper end of the threaded sleeve 22, and a threaded rod 24 threadedly connected to the threaded sleeve 22 is fixed inside the support seat 2.

[0027] In this embodiment, the driving shaft 20 is rotated by the knob to rotate the first bevel gear 21, and the meshing between the first bevel gear 21 and the second bevel gear 23 causes the second bevel gear 23 to drive the threaded sleeve 22 to rotate. The threaded force generated by the threaded connection between the threaded sleeve 22 and the threaded rod 24 causes the threaded sleeve 22 to drive the column 7 to rise and fall. During this process, the level 6 is observed to ensure that the beam 3 is in a horizontal state, which is beneficial for positioning the wheelset when the ground is uneven, thereby improving the practicability of the equipment.

[0028] like Figure 4 and Figure 5 As shown, in order to cope with the positioning of wheelsets at different heights, this embodiment provides a slide groove 16 on the side of the column 7 away from the crossbeam 3, a slide seat 18 is slidably installed inside the slide groove 16, the slide seat 18 is fixedly connected to one end of the positioning pin 8, a screw rod 17 is rotatably installed inside the slide groove 16, the screw rod 17 is threadedly connected to the slide seat 18, and the upper end of the screw rod 17 passes through the top of the column 7 and is installed with a hand wheel.

[0029] In this embodiment, the screw rod 17 is rotated by a hand wheel, and the slide 18 is threadedly connected to the screw rod 17 so that the slide 18 slides in the slide groove 16, thereby adjusting the height of the positioning pin 8 so that the positioning pin 8 can adapt to the positioning of wheelsets at different heights.

[0030] like Figure 1 and Figure 2 As shown, in order to facilitate the connection between the support assembly and the crossbeam 3, a rotating shaft 11 is rotatably installed on the side of the column 7 close to the crossbeam 3, and a through hole for plugging with the rotating shaft 11 is opened on the crossbeam 3 and the limiting slider 10.

[0031] In this embodiment, the column 7 can be installed on one side of the beam 3 by plugging the rotating shaft 11 into the through hole, so as to facilitate the storage, loading and unloading of the device and improve the portability of the device when in use.

[0032] like Figure 1 and Figure 2 As shown, in order to limit the rotating shaft 11 to prevent the rotating shaft 11 from being separated from the through hole, the rotating shaft 11 is a pipe made of stainless steel, and a receiving hole 13 is axially opened inside the rotating shaft 11, and a plug hole 12 perpendicular to the receiving hole 13 is also opened on the outside of the rotating shaft 11, a plug pin 14 is inserted into the plug hole 12, a magnet is arranged inside the plug pin 14, and the plug pin 14 is plugged into the receiving hole 13.

[0033] In this embodiment, by plugging the latch 14 into the socket 12, one end of the shaft 11 can be limited to prevent the shaft 11 from being separated from the through hole. By plugging the latch 14 into the receiving hole 13, the latch 14 can be installed inside the receiving hole 13, which is beneficial for storing the latch 14 when the support assembly is separated from the beam 3 to prevent the latch 14 from being lost.

[0034] like Figure 1 As shown, in order to facilitate the movement of the support assembly, the base 1 and the support seat 2 are welded and fixed, and rollers are installed at the bottom of the base 1 near the four corners.

[0035] The working principle and use process of the utility model are as follows: when in use, the column 7 can be installed on one side of the beam 3 by plugging the rotating shaft 11 with the through hole, and one end of the rotating shaft 11 can be limited by plugging the latch 14 with the plug hole 12, so as to prevent the rotating shaft 11 from being separated from the through hole, and the movement of the positioning plate 15 is realized by the sliding connection between the limiting slider 10 and the limiting through groove 4, and the sliding distance of the limiting slider 10 can be measured under the cooperation between the scale line 5 and the positioning plate 15, so that the distance between the two supporting components is the actual required center distance of the wheelset, and in this process, the first bevel gear 21 is rotated by rotating the driving shaft 20, and the second bevel gear 23 is meshed with the first bevel gear 21, so that the second bevel gear 23 drives the threaded sleeve 22 to rotate, and the threaded force generated by the threaded connection between the threaded sleeve 22 and the threaded rod 24 drives the column 7 to rise and fall, and at the same time, the level 6 is observed to ensure that the beam 3 is in a horizontal state, which is conducive to positioning the wheelset when the ground is uneven, thereby improving the practicality of the equipment.

[0036] The screw rod 17 is driven to rotate by the hand wheel, and the slide 18 is threadedly connected with the screw rod 17 to make the slide 18 slide in the slide groove 16, so as to adjust the height of the positioning pin 8 so that the positioning pin 8 can adapt to the positioning of wheelsets of different heights, thereby facilitating the spacing between two adjacent wheelsets and facilitating the assembly between the wheelset and the frame.
