[0046] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0047] Figure 2 A schematic diagram of the structure of a rail vehicle wheel installation and positioning device provided by an embodiment of the present invention;

[0048] Figure 3 A schematic structural diagram of a locating pin of a rail vehicle wheel installation locating device provided in an embodiment of the present invention.

[0049] Reference Figure 2 and Figure 3 An embodiment of the present invention provides a rail vehicle wheel installation and positioning device, which includes: a base plate 100 and a positioning pin 200, the base plate 100 is provided with at least two positioning holes 111, and the positions of the positioning holes 111 correspond to the positions of the pin holes on the wheel; the number of the positioning pins 200 is consistent with that of the positioning holes 111, and the positioning pins 200 are used to penetrate the positioning holes 111 and the pin holes at the first end of the connecting rod.

[0050] Specifically, the substrate 100 may be a circular plate, a square plate, a triangular plate or a plate of other shapes, which is not limited in the embodiment of the present invention. The number of positioning holes 111 provided on the substrate 100 may be two, three, four or more, and the specific number thereof is determined according to the number of pin holes on the wheel, that is, the number of positioning holes 111 is consistent with the number of pin holes on the wheel.

[0051] The position of the positioning hole 111 corresponds to the position of the pin hole on the wheel, that is, the first distance is equal to the second distance, and the distance between adjacent positioning holes 111 is equal to the distance between adjacent pin holes on the wheel. The first distance is the distance between the axis of the positioning hole 111 and the axis of the wheel shaft, and the second distance is the distance between the axis of the wheel pin hole and the axis of the wheel shaft.

[0052] The number of the locating pins 200 is consistent with the number of the locating holes 111, that is, each locating hole 111 corresponds to a locating pin 200. The locating pin 200 is inserted into the locating hole 111 and the pin hole at the first end of the connecting rod to position the pin hole at the first end of the connecting rod at a preset position. The locating pin 200 may include a cylindrical pin body and a retaining ring 210 sleeved on one end of the cylindrical pin body. The other end of the cylindrical pin body is sequentially inserted through the locating hole 111 and the pin hole at the first end of the connecting rod. The retaining ring 210 is abutted on the substrate around the locating hole 111 to prevent the locating pin 200 from penetrating into the locating hole 111 and the pin hole at the first end of the connecting rod, which is not conducive to the operation of the operator. Preferably, the retaining ring 210 and the cylindrical pin body are integrally formed as a one-piece. In order to reduce the weight of the positioning device and facilitate installation by the operator, a weight-reducing through hole is opened at the axis of the cylindrical pin body of the locating pin 200.

[0053] Preferably, the diameter of the positioning hole 111 can be consistent with the diameter of the pin hole on the wheel, and the diameter of the positioning pin 200 can be consistent with the diameter of the transmission pin for mounting the wheel, so as to avoid the positioning pin 200 having a diameter that is too small, causing the positioning pin 200 to shake in the positioning hole and the pin hole at the first end of the connecting rod, resulting in inaccurate positioning.

[0054] The following specifically describes the use process of the rail vehicle wheel installation and positioning device provided by the embodiment of the present invention:

[0055] First, insert the positioning pin 200 into the positioning hole 111 and the pin hole of the first end of the connecting rod. At this time, the first end of the connecting rod can rotate around the positioning pin 200; then, rotate the first end of the connecting rod so that the pin hole of the second end of the connecting rod is aligned with the pin hole on the transmission plate, and the transmission pin is inserted into the pin hole of the second end of the connecting rod and the pin hole of the transmission plate; then, set pressure plates at both ends of the transmission pin, and threaded holes are set on the pressure plate and the transmission pin. Use fastening bolts to thread with the pressure plate and the transmission pin in turn, so as to fix the second end of the connecting rod on the transmission plate. In order to improve the reliability of the connection, a stop washer is set between the pressure plate and the nut of the fastening bolt. According to this installation method, the second ends of all connecting rods are fixed on the transmission plate.

[0056] Secondly, pull out the positioning pin 200 and remove the rail vehicle wheel installation positioning device from the transmission plate. Since the position of the positioning hole 111 on the base plate 100 corresponds to the position of the pin hole on the wheel, at this time, the pin hole at the first end of the connecting rod corresponds to the position of the pin hole on the wheel. Then, the transmission pin is inserted into the pin hole on the wheel and the pin hole at the first end of the connecting rod, and the fastening bolt is used to thread the pressure plate and the transmission pin in turn, so as to fix the wheel to the first end of the connecting rod. In order to improve the reliability of the connection, a stop washer is provided between the pressure plate and the nut of the fastening bolt. According to this installation method, all the pin holes of the wheel are fixedly connected to the second end of the connecting rod, and the installation of the wheel can be completed.

[0057] The rail vehicle wheel installation and positioning device provided by the embodiment of the present invention is used to position and install the wheel, and the positioning is accurate, with a positioning accuracy rate of up to 100%, thereby improving the installation quality; the operation is simple and effective, reducing the labor intensity by nearly 50%; the operation is safe and reliable, without any rework, and improving the work efficiency by nearly 60%.

[0058] The rail vehicle wheel installation positioning device provided by the embodiment of the present invention provides a positioning hole corresponding to the position of the pin hole on the wheel on the base plate, and uses a positioning pin to penetrate the positioning hole and the pin hole at the first end of the connecting rod, while fixing the second end of the connecting rod on the transmission plate, accurately determines the position of the pin hole at the first end of the connecting rod, so that the position of the pin hole at the first end of the connecting rod corresponds to the position of the pin hole on the wheel, so that the wheel installation saves time and effort, has high installation efficiency, and improves the installation quality of the wheel.

[0059] Furthermore, the substrate 100 is provided with at least two positioning portions 110 , and at least one positioning hole 111 is provided on the positioning portion 110 .

[0060] There may be two, three or more positioning parts 110, and the multiple positioning parts 110 may be arranged at intervals along the circumference of the wheel axle. The embodiment of the present invention does not limit the number of positioning parts 110. One positioning part 110 may be provided with one positioning hole 111, or two, three or more positioning holes 111 may be provided on one positioning part 110. The embodiment of the present invention does not limit this.

[0061] The positioning portion 110 may be a plate body formed by the substrate 100 extending outward away from the axis of the wheel shaft. The positioning portion 110 may be an arc-shaped plate, a rectangular plate, etc. The embodiment of the present invention does not limit the specific shape of the positioning portion 110.

[0062] The following description takes the example of the connection between the wheel and the hollow shaft transmission plate through six connecting rods, that is, six pin holes are provided on the wheel, that is, the number of the positioning holes 111 is six, but the number of the positioning holes 111 of the present invention is not limited to this.

[0063] Reference Figures 1 to 3 , three positioning parts 110 are arranged on the substrate 100, and the three positioning parts 110 are evenly spaced along the weight-reducing center hole 130 on the substrate 100, wherein the weight-reducing center hole 130 is coaxial with the wheel axle. Each positioning part 110 is provided with two positioning holes 111, and there is a first angle α between the two positioning holes 111, wherein the first angle α is consistent with the angle between two adjacent pin holes that are closer to each other on the wheel. There is a second angle β between two adjacent positioning holes 111 on different positioning parts 110, that is, there is a second angle β between the positioning hole 111 and the positioning hole 112, and the second angle β is consistent with the angle between two adjacent pin holes that are farther apart on the wheel. In addition, the distances between the axis of the six positioning holes and the axis of the weight-reducing center hole 130 are consistent, and there is a first set distance L between the axis of the positioning hole 111 and the center of the weight-reducing center hole 130, and the first set distance L is consistent with the distance between the axis of the wheel pin hole and the axis of the wheel axle. That is, the positions of the six positioning holes 111 on the base plate 100 correspond one-to-one to the positions of the six pin holes on the wheel.

[0064] Furthermore, in order to facilitate the operation of the operator, a weight-reducing hole 120 is provided on the base plate 100. The weight-reducing hole 120 can be a hole of any shape, such as an arc hole, a circular hole, a rectangular hole, etc.

[0065] As a preferred embodiment of the shape of the weight-reducing hole 120, the weight-reducing hole 120 includes a first arc-shaped hole portion 121, a second arc-shaped hole portion 122 and a third arc-shaped hole portion 123; one end of the first arc-shaped hole portion 121 extends toward one of the positioning portions 110 to form the second arc-shaped hole portion 122, and the arc center of the first arc-shaped hole portion 121 is in opposite directions to the arc center of the second arc-shaped hole portion 122; the other end of the first arc-shaped hole portion 121 extends toward the adjacent positioning portion 110 to form the third arc-shaped hole portion 123, and the arc center of the first arc-shaped hole portion 121 is in opposite directions to the arc of the third arc-shaped hole portion 123.

[0066] In addition, the substrate 100 is also provided with a weight-reducing center hole 130 coaxial with the wheel axle, and the arc center of the first arc-shaped hole portion 121 coincides with the axis of the weight-reducing center hole 130. The weight-reducing center hole 130 is a circular hole coaxial with the wheel axle. It can be understood that the weight-reducing center hole 130 facilitates the processing and positioning of the positioning hole 111 while reducing weight.

[0067] Continue to refer to Figure 1, the arc center of the first arc-shaped hole portion 121 of the weight-reducing hole 120 coincides with the axis of the weight-reducing center hole 130, that is, the arc center of the outer arc side of the first arc-shaped hole portion 121 coincides with the axis of the weight-reducing center hole 130, and the arc center of the inner arc side of the first arc-shaped hole portion 121 coincides with the axis of the weight-reducing center hole 130. One end of the first arc-shaped hole portion 121 extends toward one of the positioning portions 110 to form a second arc-shaped hole portion 122, and the arc center of the first arc-shaped hole portion 121 is in opposite directions to the arc center of the second arc-shaped hole portion 122, that is, the arc center of the second arc-shaped hole portion 122 is on the side away from the axis of the weight-reducing center hole 130. The other end of the first arc-shaped hole portion 121 extends toward the adjacent positioning portion 110 to form a third arc-shaped hole portion 123, and the arc center of the first arc-shaped hole portion 121 is in the opposite direction to the arc of the third arc-shaped hole portion 123, that is, the arc center of the third arc-shaped hole portion 123 is on the side away from the axis of the weight-reducing center hole 130.

[0068] In this embodiment, the first arc-shaped hole portion 121, the second arc-shaped hole portion 122, and the third arc-shaped hole portion 123 form a W-shaped structure of a weight-reducing hole, which reduces the weight of the positioning device and facilitates the operator to take it. While ensuring the structural stability of the positioning device, the weight-reducing hole 120 is as large as possible, and the embodiment of the present invention does not limit the size of the weight-reducing hole 120.

[0069] Of course, one or more weight-reducing holes 120 may be provided, and the plurality of weight-reducing holes 120 may be arranged at intervals along the circumferential direction of the weight-reducing center hole 130. Two, three, four, or more weight-reducing holes 120 may be provided, and the embodiment of the present invention does not limit this. Figure 2 There are three weight-reducing holes 120 , and the three weight-reducing holes 120 are arranged at intervals along the circumferential direction of the weight-reducing center hole 130 .

[0070] In order to further improve the structural stability of the positioning device, a reinforcing rib plate 140 is provided on the side of the base plate 100 away from the transmission plate, and the reinforcing rib plate 140 is perpendicular to the base plate 100 .

[0071] Specifically, the reinforcing rib plate 140 can also be a flat plate, for example, a rectangular plate, or an arc-shaped plate, and the reinforcing rib plate 140 is perpendicular to the base plate 100. Preferably, the reinforcing rib plate 140 is a long strip rib plate, which is arranged perpendicular to the base plate 100, and the reinforcing rib plate 140 is welded on the side of the base plate 100 away from the transmission plate.

[0072] The reinforcing rib plate 140 may be disposed on the weight-reducing hole 120 , and the embodiment of the present invention does not limit the position of the reinforcing rib plate 140 .

[0073] As a preferred embodiment of the installation position of the reinforcing rib plate, one end of the long rib plate is located at the positioning portion 110 , and the other end of the long rib plate is located at the axis of the weight-reducing center hole 130 .

[0074] Continue to refer to Figure 2 One end of the long rib plate is located between the two positioning holes 111 on the positioning portion 110, and the other end of the long rib plate passes through the substrate 100 between two adjacent weight-reducing holes 120 and extends to the axis of the weight-reducing center hole 130, that is, the long rib plate radiates outward from the axis of the weight-reducing center hole 130 to between the two positioning holes 111 on the positioning portion 110.

[0075] One reinforcing rib plate 140 may be provided. Preferably, there are multiple reinforcing rib plates 140, and the multiple reinforcing rib plates 140 are arranged at intervals along the circumferential direction of the weight-reducing center hole 130, and the multiple reinforcing rib plates 140 are fixedly connected at the axis of the weight-reducing center hole 130. For example, referring to Figure 2 There are three reinforcing rib plates 140 , which are welded at the weight-reducing center hole 130 , and the angle between two adjacent reinforcing rib plates 140 is 120 degrees.

[0076] In order to facilitate the connection between the connecting rod and the transmission plate, an avoidance opening 150 for avoiding the second end of the connecting rod is provided on the base plate 100 , and the avoidance opening 150 is located between two adjacent positioning portions 110 .

[0077] Specifically, the avoidance opening 150 may be a rectangular opening, an arc opening or an irregular opening, etc., which is not limited in the embodiment of the present invention. The avoidance opening 150 is arranged between two adjacent positioning parts 110. The number of the avoidance openings 150 is determined according to the number of pin holes to be connected on the transmission disk, and the avoidance openings 150 can be used to install two connecting rods on the transmission disk. For example, referring to Figure 2 The substrate 100 is provided with three avoidance openings 150, and the three avoidance openings 150 are arranged at intervals along the circumference of the weight-reducing central hole 130. The embodiment of the present invention does not limit the number of the avoidance openings.
