DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.
[0030] According to an embodiment of the present invention, a straddle-type monorail bogie is provided, including a loop frame 1, such as... Figure 1 As shown, a traveling wheel 2 is provided in the middle of the loop frame 1. The traveling wheel 2 is connected to the side of the upright plate 3 at the center of the top side of the loop frame 1 through the wheel axle. The traveling wheel 2 passes through the loop frame 1 and the bottom of the traveling wheel 2 contacts the track surface. On both sides of the loop frame 1 at the same level as the upright plate 3, there is a set of fixing blocks 4. A stabilizing wheel 5 is provided between the fixing blocks 4. The stabilizing wheel 5 contacts the top surface of the track. When the bogie is running, the stabilizing wheel 5 will play a positioning role and realize the control of the position of the traveling wheel 2 and the center line of the track. On the other two opposite sides of the loop frame 1, there are connecting auxiliary parts 6.
[0031] Among them, according to Figures 6-8 As shown, the connecting auxiliary part 6 includes a U-shaped plate 28 fixed to the side of the U-shaped frame 1. An extension protrusion is provided at the center of the top and bottom of the U-shaped plate 28. An L-shaped frame 35 is provided at the center of the outer side of the extension protrusion. A support plate 37 is provided on the top of the L-shaped frame 35. Support rods 39 that can support the chassis base 38 are provided around the top of the support plate 37. The motor 40 is mounted on the chassis base 38.
[0032] On the other hand, an arc-shaped frame 33 is provided horizontally in the U-groove of the U-shaped plate 28. The arc-shaped frame 33 is movably connected to the groove wall. The right side of the arc-shaped frame 33 is connected to the motor 41 installed on the support plate 43 via the output shaft 2. Driven by the motor 41, the output shaft 2 rotates accordingly, thereby driving the arc-shaped frame 33 to swing up and down.
[0033] In particular, an arc frame 34 is set in the longitudinal direction inside the arc frame 33, that is, in the groove of the U-shaped plate 28. The two ends of the arc frame 34 are movably connected to the corresponding L-shaped frame 35. The upper part of the arc frame 34 is connected to the motor 40 through the output shaft. When the motor 40 is driven, the motor 40 will drive the arc frame 34 to swing left and right.
[0034] In this design, a connecting rod 36 is inserted into the hole at the intersection of the first arc frame 34 and the second arc frame 33. A fixing block 50 is provided at the outer end of the connecting rod 36. The outer side of the fixing block 50 is fixed at the center of the side of the frame body 7. A guide slider 49 is provided at the inner end of the connecting rod 36. The guide slider 49 is embedded in the transverse groove 47 of the self-weight adjusting ball 46 and slides transversely in the transverse groove 47. An arc slider 45 is embedded in the longitudinal groove 48 on the other side of the self-weight adjusting ball 46 and slides longitudinally in the longitudinal groove 48. When the angle sensor detects that the frame 7 is tilted horizontally due to external factors, if the fixed block 50 connected to the frame 7 is detected to shift to the left or right, a trigger switch linked to the motor 40 is activated, driving the motor 40 to run. The motor 40 then drives the arc frame 34 to move in the opposite direction of the shift, causing the arc frame 34, along with the connecting rod 36 inserted in the middle, to move laterally within the transverse groove 47, carrying the guide slider 49. This causes the fixed block 50 to move laterally along the central opening of the arc frame 33. After adjusting the horizontal plane of the frame 7 to a suitable position, the sliding stops. When the angle of the fixed block 50 is detected to shift upwards or downwards, a trigger switch connected to the motor 41 is activated, driving the motor 41 to run. The motor 41 drives the arc-shaped frame 33 to rotate, which in turn drives the connecting rod 36, causing the self-weight adjusting ball 46 to rotate up and down. The longitudinal groove 48, limited by the arc-shaped slider 45, maintains the rotation angle of the self-weight adjusting ball 46, preventing angle shift during up and down rotation. The inner side of the arc-shaped slider 45 is fixed to the side of the disc 44, which is fixed to the inner wall of the U-shaped plate 28. Therefore, the arc-shaped slider 45 is stationary and will not rotate due to the influence of the self-weight adjusting ball 46. This adjustment method maintains the balance of the frame 7 and prevents changes in the center force point of the frame 7 from affecting the stability of the bogie.
[0035] On the other hand, such as Figures 2-5 As shown, a detector is installed on the axial angle adjustment unit 8. The detector can detect the tilt angle of the guide wheel 10 within a range of ±5° with a detection accuracy of 0.1°. The detector can be installed on the outer side of the middle of the shaft 9, parallel to the axis of the guide wheel 10. When the detected tilt angle is greater than 1°, the corresponding motor will be triggered. When the guide wheel 10 tilts due to external factors, the detector detects the tilt angle and triggers a touch switch linked to motor 3 16 or motor 4 19. By detecting the offset direction of the tilt angle, motor 3 16 or motor 4 19 is driven. Motor 3 16 or motor 4 19 drives the corresponding first axial angle frame 11 or second axial angle frame 13 to move, thereby automatically adjusting the offset angle of the guide wheel 10 and correcting the angle of the guide wheel 10 to keep the angle of the guide wheel 10 in a balanced state.
[0036] Wherein, the top of the guide wheel 10 is provided with a shaft 9, the shaft 9 is connected with a fixed block three 15, the top of the fixed block three 15 is provided with a second axial angle frame 13, the second axial angle frame 13 is a U-shaped structure, a group of second supports 23 are arranged in the groove of the second axial angle frame 13, a worm two 20 is arranged transversely between the second supports 23, one end of the worm two 20 penetrates through the second axial angle frame 13 and is connected with a motor four 19 installed on the side of the second axial angle frame 13, a second arc-shaped lugs 30 and a first lower tooth 29 are respectively arranged on the top of the other two sides of the second axial angle frame 13, a second arc-shaped sliding groove 31 is arranged on the outside bottom of the second arc-shaped lugs 30, a second U frame 14 is embedded in the second arc-shaped sliding groove 31, second lower teeth 32 which are engaged with the first lower tooth 29 are arranged on the both sides of the bottom of the second U frame 14, wherein, a second half wheel plate 21 which is engaged with the worm two 20 is arranged in the center of the U groove of the second U frame 14, the bottom of the second half wheel plate 21 is a gear structure, a first U frame 12 is arranged on the top of the second U frame 14, and the structures of the first U frame 12 and the first axial angle frame 11 are the same as those of the second U frame 14 and the second axial angle frame 13.
[0037] Wherein, when the motor three 16 operates and the motor four 19 stops working, the motor three 16 drives the worm one 17 to rotate, the worm one 17 drives the first half wheel plate 18 engaged below to rotate, the first half wheel plate 18 further drives the first U frame 12, since the first U frame 12 and the second U frame 14 are fixedly connected, the first U frame 12 drives the second U frame 14 to move synchronously when the first U frame 12 moves, and the second U frame 14 drives the second axial angle frame 13 to move forward and backward.
[0038] Wherein, when the driving motor four 19 operates and the motor three 16 stops working, the motor four 19 drives the worm two 20 to rotate, the worm two 20 drives the second half wheel plate 21 to swing, the second half wheel plate 21 drives the second U frame 14, the second U frame 14 drives the first axial angle frame 11 to move left and right through the first U frame 12.
[0039] Wherein, when the motor three 16 and the motor four 19 are simultaneously driven, the first axial angle frame 11 and the second axial angle frame 13 are simultaneously moved forward and backward and left and right, the guide wheel 10 is angle-controlled through the multi-directional adjustment, the guide wheel 10 always maintains a balanced state, and therefore the stability of the bogie in the running process is improved.
[0040] The above only describes the preferred embodiments of the present application and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
