DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0028] The technical solutions disclosed in various embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1

[0030] Please refer to Figures 1 to 5 As shown, an embodiment of the utility model discloses a guide assembly for a monorail walking device, and the disclosed guide assembly includes a rotary drive mechanism and a first roller bracket 150 and a second roller bracket 151 arranged relatively to each other; the first roller bracket 150 and the second roller bracket 151 are rotatably arranged and are transmission-connected to the rotary drive mechanism, and the rotary drive mechanism controls the first roller bracket 150 and the second roller bracket 151 to rotate to a working state and a retracted state.

[0031] Among them, Figure 4 As shown, when the first roller bracket 150 and the second roller bracket 151 are rotated to the working state of the vertical support edge, the first roller bracket 150 and the second roller bracket 151 are respectively located on the two side sides of the rail head, and the guide rollers 1503 of the first roller bracket 150 and the second roller bracket 151 are respectively in contact with the two side sides of the rail head, which can prevent the vehicle body 100 from deviating left and right when walking along the single rail 200 and maintain the state of walking along the center line of the top surface of the rail head, thereby improving the reliability of the vehicle body 100 walking along the single rail 200, and is well suitable for the walking needs of the vehicle body 100 along the single rail 200.

[0032] After the first roller bracket 150 and the second roller bracket 151 are rotated to the retracted state, the first roller bracket 150 and the second roller bracket 151 are located above the walking contact surface of the walking mechanism, that is, the first roller bracket 150 and the second roller bracket 151 are close to the bottom of the vehicle body 100 as a whole. Compared with the first roller bracket 150 and the second roller bracket 151, they always maintain a vertical supporting edge working state, which is not only convenient for the storage, carrying and idle placement of the vehicle body 100, but also makes the vehicle body 100 suitable for walking needs in other platform scenarios.

[0033] In the guide assembly disclosed in this embodiment, as a rotation setting mode of the first roller bracket 150 and the second roller bracket 151, the rotation setting directions of the first roller bracket 150 and the second roller bracket 151 can be the same and consistent with the walking direction of the vehicle body 100, that is, the first roller bracket 150 and the second roller bracket 151 can rotate forward or backward at the same time, so as to facilitate the use of a single power source to simultaneously drive the first roller bracket and the second roller bracket to rotate.

[0034] But preferably, if Figure 1 , Figure 3 and Figure 4 As shown, the first roller bracket 150 and the second roller bracket 151 rotate relative to each other, that is, the rotation direction of the first roller bracket 150 and the second roller bracket 151 is perpendicular to the moving direction of the vehicle body 100, and the rotary drive mechanism controls the first roller bracket 150 and the second roller bracket 151 to rotate in opposite closing directions to a working state, and the rotary drive mechanism controls the first roller bracket 150 and the second roller bracket 151 to rotate in opposite opening directions to a retracted state; this arrangement is conducive to limiting the freedom of the first roller bracket 150 and the second roller bracket 151 in the moving direction of the vehicle body 100, and avoiding the first roller bracket 150 and the second roller bracket 151 from deflecting forward or backward during the movement of the vehicle body 100 and affecting the performance of the guide assembly.

[0035] At the same time, in order to realize the setting that a single power source can simultaneously drive and control the rotation of the first roller bracket 150 and the second roller bracket 151, the rotation drive mechanism includes a driving motor 1505 and a gear part 1504 arranged at the end of the first roller bracket 150 and the second roller bracket 151; the gear part 1504 of the first roller bracket 150 is meshed with the gear part 1504 of the second roller bracket 151, and the gear part 1504 is provided with a rotating shaft 1506 for rotationally connecting with the vehicle body 100; the first roller bracket 150 or the second roller bracket 151 is transmission-connected with the driving motor 1505; wherein the driving motor 1505 is a motor with a self-locking function, so that the first roller bracket 150 and the second roller bracket 151 can be locked in a corresponding state after the driving motor 1505 is powered off.

[0036] Specifically, Figure 1 and Figure 3 As shown, the output shaft of the drive motor 1505 can be directly connected to the rotating shaft 1506 of the first roller bracket 150 or the second roller bracket 151; of course, as other transmission connection methods, the output shaft of the drive motor 1505 can also be connected to the gear part 1504 of the first roller bracket 150 or the second roller bracket 151 through a gear assembly.

[0037] Preferably, if Figure 1 and Figure 2 As shown, the gear portion 1504 is provided with a planar area and an arc-shaped area, and the arc-shaped area is provided with a tooth portion, and the planar area is used to connect with the end of the corresponding first roller bracket 150 or the second roller bracket 151; therefore, the gear portion 1504 of this shape structure not only ensures the rotational engagement, but also facilitates the connection setting of the bracket part.

[0038] Specifically, Figure 1 and Figure 2 As shown, the first roller bracket 150 and the second roller bracket 151 each include a vertical portion 1501 and a shoulder 1502; one end of the shoulder 1502 is connected to the gear portion 1504, and the other end of the shoulder 1502 is obliquely downward away from the vehicle body 100 and connected to the vertical portion 1501, and the shoulder 1502 of the first roller bracket 150 and the shoulder 1502 of the second roller bracket 151 are relatively in an "eight" shape; the shoulder 1502 and the vertical portion 1501 are both provided with guide rollers 1503, so that The guide roller 1503 arranged on the vertical portion 1501 can contact the side of the rail head, and the guide roller 1503 arranged on the shoulder 1502 can contact the arc-shaped transition section between the top surface of the rail head and the side of the rail head. When the car body 100 tilts and causes the guide roller 1503 of the vertical portion 1501 to fail, the guide roller 1503 of the shoulder 1502 can still maintain guiding contact with the rail 200, thereby better improving the reliability of the monorail traveling device traveling along a single rail 200.

[0039] Example 2

[0040] Based on the guide assembly disclosed in Example 1, this embodiment discloses a monorail running device, and the disclosed monorail running device includes a vehicle body 100, a running mechanism, and the guide assembly described in Example 1; Figure 5As shown, the walking mechanism and the guide assembly are both arranged at the bottom of the vehicle body 100, and the walking mechanism includes a driving wheel 130 arranged at the front end area of ​​the bottom of the vehicle body 100 and a driven wheel 140 arranged at the rear end area of ​​the bottom of the vehicle body 100. The driving wheel 130 adopts a wheel motor structure to provide walking power for the vehicle body 100, and cooperates with the driven wheel 140 to realize the walking function of the vehicle body 100, which belongs to the prior art and will not be described in detail in this embodiment.

[0041] Meanwhile, the guide assembly is located between the driving wheel 130 and the driven wheel 140; preferably, as Figure 3 and Figure 5 As shown, the number of guide assemblies can be two groups, both of which are located between the driving wheel 130 and the driven wheel 140, and one of the two groups of guide assemblies is close to the driving wheel 130, and the other group is close to the driven wheel 140. Compared with the structure in which only one group of guide assemblies is set, the guiding effect of the guide assemblies on the vehicle body 100 can be better guaranteed, so that the movement of the vehicle body 100 along the single rail 200 can be more stable.

[0042] In order to facilitate the installation of the driven wheel 140, a mounting groove for mounting the driven wheel 140 is provided at the bottom of the vehicle body 100. However, the design of the mounting groove easily causes dust and other debris to enter the interior of the vehicle body 100 through the groove, thereby causing a safety hazard. In view of this, in this embodiment, a corresponding driven wheel mounting support 141 is provided at the mounting groove of the vehicle body 100, and Figure 6 As shown, the driven wheel mounting support 141 is a semi-cylindrical protective cover structure adapted to the driven wheel 140 , and a rotating shaft 142 is provided at both end surfaces of the driven wheel mounting support 141 , and the driven wheel 140 is assembled on the rotating shaft 142 through bearings.

[0043] It is easy to understand that in order to prevent the end face of the driven wheel 140 from rubbing against the driven wheel mounting support 141 at both ends of the rotating shaft 142 and affecting the walking and rotation of the driven wheel 140, the end faces at both ends of the driven wheel mounting support 141 are respectively provided with annular bosses 143 distributed along the circumference of the rotating shaft 142, so that the inner ring of the bearing is supported by the annular boss 143, so that the end face of the driven wheel 140 and the end face of the driven wheel mounting support 141 maintain a certain distance, thereby avoiding contact friction between the two.

[0044] The above embodiments of the present invention focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0045] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
