[0030] Please see Figure 1 This application provides a traveling device 10, applied to a furnace door service vehicle, which drives the entire furnace door service vehicle to travel on a track. In this embodiment, the traveling device 10 includes a traveling mechanism 100 and a connecting mechanism 200. The traveling mechanism 100 travels on the track, and the connecting mechanism 200 connects the traveling mechanism 100 to the steel beam 20 of the furnace door service vehicle body. The steel beam 20 forms the frame of the furnace door service vehicle. Thus, when the traveling mechanism 100 travels on the track, the connecting mechanism 200 can drive the entire furnace door service vehicle to travel on the track.

[0031] Please see Figure 1 and Figure 2 The connecting mechanism 200 includes a first base 210, a second base 220, a first pin 230, a second pin 240, a first universal bearing 250, and a second universal bearing 260. The first base 210 has a first inner hole 211, the first pin 230 passes through the first base 210 and the second base 220, and the first universal bearing 250 is assembled to the first pin 230 and contacts the inner wall of the first inner hole 211. The second base 220 has a second inner hole 221, the second pin 240 passes through the second base 220 and the traveling mechanism 100, and the second universal bearing 260 is assembled to the second pin 240 and contacts the inner wall of the second inner hole 221.

[0032] The axis of the first pin 230 is parallel to the tangent of the track, and the axis of the second pin 240 is perpendicular to the tangent of the track.

[0033] The first base 210 and the second base 220 at least partially overlap, so that the first pin 230 can pass through both the first base 210 and the second base 220 simultaneously to connect them. The first pin 230 also passes through the first inner hole 211, allowing the first universal bearing 250 mounted on the first pin 230 to contact the inner wall of the first inner hole 211. The first pin 230, the first universal bearing 250, and the first inner hole 211 are all fitted with tolerances.

[0034] Similarly, the second base 220 and the traveling mechanism 100 at least partially overlap, so that the second pin 240 can pass through both the second base 220 and the traveling mechanism 100 simultaneously to connect them. The second pin 240 also passes through the second inner hole 221, allowing the second universal bearing 260, mounted on the second pin 240, to contact the inner wall of the second inner hole 221. There are tolerance fits between the second pin 240, the second universal bearing 260, and the second inner hole 221.

[0035] The first base 210 is used to connect with the steel beam 20 of the car body, and the second base 220 is connected with the traveling mechanism 100. Thus, when the traveling mechanism 100 travels on the track, it can drive the furnace door service car as a whole to travel on the track through the connecting mechanism 200.

[0036] The first universal bearing 250 and the second universal bearing 260 can swing or rotate in multiple directions (angles). Therefore, when the track is deformed, the connecting mechanism 200 can automatically correct the position of the furnace door service vehicle in the rotation range of the first universal bearing 250 and the second universal bearing 260 in the parallel and perpendicular directions of the track tangent, so that the furnace door service vehicle can travel as smoothly as possible along the track.

[0037] Specifically, the first universal bearing 250 and the second universal bearing 260 can be spherical plain bearings.

[0038] Please see Figure 1 In some embodiments, the first base 210 includes a mounting member 212, the second base 220 includes a mounting groove 222, the mounting member 212 is located in the mounting groove 222, and a first inner hole 211 is disposed in the mounting member 212.

[0039] Since the mounting component 212 is located in the mounting groove 222, there is an overlapping part between the first base 210 and the second base 220. The first inner hole 211 is provided in the mounting component 212, and the first pin 230 also passes through the mounting component 212 and the second base 220 to connect the first base 210 and the second base 220.

[0040] Please see Figure 3and Figure 4 In some embodiments, the traveling mechanism 100 includes a drive assembly 110, a first wheel pair 120, a second wheel pair 130, a first connecting plate 140, a second connecting plate 150, and a third connecting plate 160. The first connecting plate 140 and the second connecting plate 150 are respectively disposed on both sides of the third connecting plate 160. A second pin 240 passes through the third connecting plate 160. The first wheel pair 120 is mounted on the first connecting plate 140, and the second wheel pair 130 is mounted on the second connecting plate 150. The drive assembly 110 is used to drive the first wheel pair 120 and the second wheel pair 130 to rotate.

[0041] The first wheel pair 120 and the second wheel pair 130 are used to bear the weight of the service vehicle and ultimately achieve movement. The second pin 240 passes through the third connecting plate 160, thereby connecting the second base 220 and the traveling mechanism 100, so that the traveling mechanism 100 can drive the furnace door service vehicle to move as a whole through the connecting mechanism 200.

[0042] The first connecting plate 140 and the second connecting plate 150 are connected to the third connecting plate 160, and the first connecting plate 140 and the second connecting plate 150 are arranged opposite to each other. Since the first wheel pair 120 is installed on the first connecting plate 140 and the second wheel pair 130 is installed on the second connecting plate 150, the first wheel pair 120 and the second wheel pair 130 are also arranged opposite to each other. The drive assembly 110 drives the first wheel pair 120 and the second wheel pair 130 to rotate, so that the first wheel pair 120 and the second wheel pair 130 can travel on the track.

[0043] Specifically, the second universal bearing 260 can be disposed between the first connecting plate 140 and the second connecting plate 150. In order to make the overall structure of the traveling mechanism 100 more stable, multiple connecting shafts 170 are also connected between the first connecting plate 140 and the second connecting plate 150.

[0044] Please see Figures 1-4 In some embodiments, the drive assembly 110 includes a drive member 111 and a transmission member 112. The drive member 111 is mounted on the first connecting plate 140 or the second connecting plate 150, and the transmission member 112 passes through the first connecting plate 140 or the second connecting plate 150 to drive the first wheelset 120 and the second wheelset 130. The drive member 111 drives the first wheelset 120 and the second wheelset 130 to rotate through the transmission member 112.

[0045] The first gear pair 120 includes a first driving gear 121 and a first driven gear 122, and the second gear pair 130 includes a second driving gear 131 and a second driven gear 132. The first driving gear 121 and the second driving gear 131 mesh with the transmission member 112 for transmission. That is, the transmission member 112 is provided with two gears 116, and the outer rings of the first driving gear 121 and the second driving gear 131 are provided with serrated teeth. The two gears 116 mesh with the first driving gear 121 and the second driving gear 131 respectively for transmission. The driving member 111 drives the transmission member 112 to rotate, which in turn drives the first driving gear 121 and the second driving gear 131 to rotate to achieve movement.

[0046] It should be noted that when the furnace door service vehicle is subjected to torque, it will be transmitted to the first connecting plate 140 and the second connecting plate 150 through the wheels, which can easily cause deformation of the first connecting plate 140 and the second connecting plate 150. Therefore, as mounting components for the wheelset and the drive component 111, the first connecting plate 140 and the second connecting plate 150 are both integral structures, that is, there are no hollow parts on the first connecting plate 140 and the second connecting plate 150. As a result, the overall structure of the first connecting plate 140 and the second connecting plate is strong, so as to resist deformation under stress as much as possible.

[0047] Specifically, the drive component 111 includes a reducer and a drive motor connected by a transmission connection, and the transmission component 112 can be a gear 116 shaft. The output shaft of the drive motor is equipped with a bevel gear 116, and the two transmit power through gear 116 meshing, using gear 116 oil for splash lubrication; one end of the reducer is equipped with a connecting flange, and the reducer housing has pre-drilled bolt holes for easy installation in any position; the output shaft of the reducer is a hollow shaft, facilitating connection to the transmission component 112. The material of the transmission component 112 can be 42CrMo, requiring heat treatment; after heat treatment, the surface of the gear 116 needs to undergo a quenching process to obtain higher hardness; the journal of the transmission component 112 is connected to the hollow shaft of the reducer via a key fit.

[0048] In addition, the transmission component 112 is also equipped with two transmission bearings 113. The two transmission bearings 113 are arranged one-to-one with the first connecting plate 140 and the second connecting plate 150. The two transmission bearings 113 are respectively disposed within the first connecting plate 140 and the second connecting plate 150. The two transmission bearings 113 are used to support the transmission component 112 and make the inner ring rotate together with the transmission component 112, while the outer ring contacts the first connecting plate 140 / second connecting plate 150. The transmission component 112 is also provided with a bearing cover 114 and a bearing end cover 115. The bearing cover 114 is connected to the second connecting plate 150 and is used to position the outer ring of one of the transmission bearings 113. The bearing end cover 115 is connected to the first connecting plate 140 and is used to position the outer ring of the other transmission bearing 113, and has dustproof and oil storage functions.

[0049] Based on the same inventive concept, please refer to Figure 1 This application provides a furnace door service vehicle, including a vehicle body steel beam 20 and the aforementioned traveling device 10, with the vehicle body steel beam 20 connected to a first base 210. The beneficial effects of the furnace door service vehicle provided in this application are the same as those of the aforementioned traveling device 10, and will not be repeated here.

[0050] Based on the same inventive concept, please refer to Figure 3 This application also provides a furnace door service vehicle track system, including the furnace door service vehicle described above, with track body 30. The beneficial effects of the furnace door service vehicle track system provided in this application are the same as those of the traveling device 10 described above, and will not be repeated here.

[0051] In some embodiments, the track body 30 includes a reinforcing rib 40, an upper flange, a lower flange, and a web connecting the upper flange and the lower flange. The traveling mechanism 100 travels on the lower flange, and the reinforcing rib 40 is disposed below the lower flange.

[0052] That is, the track body 30 is an I-beam track with an I-shaped cross section. Since the lower flange needs to bear the first wheel pair 120 and the second wheel pair 130, a reinforcing rib plate 40 is set at the bottom of the lower flange to enhance the structural strength of the lower flange and reduce deformation.

[0053] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0054] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
