Description

Technical Field

[0001] This utility model relates to the field of engineering vehicle technology, and in particular to a mixing tank drive fixing structure for a tracked mixing tank truck and the tracked mixing tank truck. Background Technology

[0002] Tracked concrete mixer trucks are special engineering vehicles designed specifically for concrete construction in complex terrains. They combine mixing, transportation, and off-road capabilities, making them suitable for harsh environments where traditional wheeled mixer trucks cannot operate. They play an irreplaceable role in fields such as mining, water conservancy, and the military.

[0003] Currently, tracked mixer trucks typically drive their mixing tanks via chain drive. A drive motor is mounted at a specific location on the tank's support frame, with a drive sprocket attached to the motor's output shaft. A rotating connecting shaft is located at the tank's end cap, with a driven sprocket mounted on its end. The drive and driven sprockets are connected by a chain. When the tank rotates, the drive motor's output shaft rotates the drive sprocket, which in turn drives the driven sprocket via the chain. The driven sprocket then drives the connecting shaft at the tank's end cap, thus rotating the tank. While this chain drive achieves mixing, it is difficult to assemble, and the chain can loosen after a period of operation, affecting mixing efficiency. Therefore, reducing the assembly difficulty of the mixing tank's drive structure and improving its mixing efficiency are pressing technical challenges. Utility Model Content

[0042] In the following description, embodiments of the present invention will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals denote the same or similar parts.

[0043] Figure 1 This is a schematic diagram of the mixing tank drive and fixing structure for a tracked mixing tank truck according to an embodiment of the present invention. Figure 2 This is a partial cross-sectional schematic diagram of the stirring tank drive fixing structure according to an embodiment of the present invention, as shown below. Figure 1 and Figure 2 As shown, the mixing tank drive fixing structure includes at least a mixing tank 100, a main support 200, a main rotary bearing 310, and a rotary drive component 320.

[0044] A main support 200 is used to fix itself to the body of the tracked mixer truck, and the main support 200 has a shaft hole; a main rotary bearing 310 is coaxially arranged with the shaft hole, the outer ring of the main rotary bearing 310 is fixedly connected to the main support 200, and the inner ring of the main rotary bearing 310 is connected to the fixed connecting plate 110 at the end of the mixing tank 100; a rotary drive component 320 is fixed on the side of the main support away from the mixing tank 100, the output end of the rotary drive component 320 is coaxial with the shaft hole, and the output end of the rotary drive component 320 is connected to the inner ring of the main rotary bearing 310.

[0045] In the above embodiment, the main support 200 is fixed relative to other components, and the mixing tank 100 is located above the main support 200. Specifically, the bottom of the main support 200 may be provided with connecting lugs for fixed connection with the tracked mixing tank vehicle body; that is, the main support 200 and the tracked mixing tank vehicle body are connected by a detachable connection. The main rotary bearing 310 is specifically located on one side of the shaft hole of the main support. Figure 1 and Figure 2 In this case, the main rotary bearing 310 is specifically located on the left side of the shaft hole. At this time, the mixing tank 100 is also located on the left side of the shaft hole of the main support, and the main rotary bearing 310 is located between the shaft hole of the main support 200 and the fixed connecting plate 110 at the end of the mixing tank 100. Figure 7 This is a schematic diagram of the structure of the mixing tank 100, as shown below. Figure 7As shown, the fixed connecting plate 110 is specifically located at the right end of the mixing tank 100. The main rotary bearing 310 serves as a support bearing for the rotation of the mixing tank 100 relative to the main support 200. The main rotary bearing 310 specifically includes an inner ring, an outer ring, and a rotating body. At this time, the outer ring of the main rotary bearing 310 is fixedly connected to the main support 200, while the inner ring of the main rotary bearing 310 is connected to the fixed connecting plate 110 at the end of the mixing tank 100; as shown... Figure 8 and Figure 9 As shown, the inner and outer rings of the main rotary bearing 310 may each have multiple mounting holes. In this embodiment, to facilitate the disassembly of the mixing tank 100 and the main rotary bearing 310, the mixing tank 100 and the main rotary bearing 310, as well as the main rotary bearing 310 and the main support 200, are connected by a detachable connection. Figure 3 As shown, the rotary drive component 320 can be specifically arranged on the right side of the main support 200, that is, on the right side of the shaft hole of the main support 200. At this time, the main rotary bearing 310 and the rotary drive component 320 are respectively located on the left and right sides of the shaft hole. The rotary drive component 320 is specifically fixed on the main support 200, and the output end of the rotary drive component 320 can be further connected to the inner ring of the main rotary bearing 310. That is, the rotation of the output end of the rotary drive component 320 can drive the inner ring of the main rotary bearing 310 to rotate, and the inner ring of the main rotary bearing 310 further drives the mixing tank 100 to rotate. For example, the rotary drive component 320 can be a rotary motor or a rotary electric motor.

[0046] In some embodiments, the mixing tank drive fixing structure includes a coupling 330, which is disposed between the output end of the rotary drive component 320 and the inner ring of the main rotary bearing 310. In this embodiment, the output end of the rotary drive component 320 and the inner ring of the main rotary bearing 310 are connected by the coupling 330, and the coupling 330 is detachably connected to both the output end of the rotary drive component 320 and the main rotary bearing 310. Figure 2 As shown, the coupling 330 is also located on the left side of the main support 200. At this time, the output shaft of the rotary drive component 320 passes through the shaft hole on the main support 200 and is connected to the coupling 330.

[0047] For example, the coupling 330 has a spline sleeve for connection to the output end of the rotary drive component 320, the output end of which is a spline shaft, and the spline shaft is disposed within the spline sleeve. Figure 12 and Figure 13 As shown, the coupling 330 includes a shaft section and a flange located outside the shaft section. In this embodiment, a spline sleeve is provided through the shaft section for engaging with... Figure 3The splined output shaft of the rotary drive component 320 shown is connected; the flange has multiple mounting holes, which serve as bolt holes, allowing the flange on the coupling 330 to be fixedly connected to the inner ring of the main rotary bearing via bolts. It is understood that this embodiment, which uses a splined sleeve for the shaft hole on the coupling 330 to connect with the rotary drive component 320 and a splined shaft for the output shaft of the rotary drive component 320, is merely an example; in other embodiments, the output shaft of the rotary drive component 320 can also be a plain shaft, in which case the output shaft of the rotary drive component 320 can be further connected to the shaft hole of the coupling 330 via a flat key.

[0048] Furthermore, the fixed connecting plate 110, the inner ring of the main rotary bearing 310, and the coupling 330 all have multiple corresponding bolt fixing holes, and the fixed connecting plate 110, the inner ring of the main rotary bearing 310, and the coupling 330 are fixed together by bolts. As can be seen from the above embodiment, the inner ring of the main rotary bearing 310 is connected to both the fixed connecting plate 110 and the coupling 330. To further save assembly time of the mixing tank drive fixing structure, the bolt fixing holes on the inner ring of the main rotary bearing 310, the fixed connecting plate 110, and the coupling 330 correspond to each other. At this time, the inner ring of the main rotary bearing 310, the fixed connecting plate 110, and the coupling 330 are connected by a long bolt, that is, the fixed connecting plate 110, the inner ring of the main rotary bearing 310, and the coupling 330 are connected together by this long bolt. It is understood that the connection of the fixed connecting plate 110, the inner ring of the main rotary bearing 310, and the coupling 330 by long bolts in this embodiment is only an example. In other embodiments, the fixed connecting plate 110, the inner ring of the main rotary bearing 310, and the coupling 330 may also be connected in pairs.

[0049] In one embodiment, the mixing tank drive fixing structure includes a drive component fixing frame 340, which is disposed between the rotary drive component 320 and the main support 200. The drive component fixing frame 340 has an output shaft through hole, which is coaxial with the shaft hole. In this embodiment, the drive component fixing frame 340 is connected to both the rotary drive component 320 and the main support 200; that is, the rotary drive component 320 is fixed to the main support 200 via the drive component fixing frame 340. The output shaft through hole on the drive component fixing frame 340 is coaxial with the shaft hole on the main support 200. In this case, the output shaft of the rotary drive component 320 passes through both the output shaft through hole on the drive component fixing frame 340 and the shaft hole on the main support 200, and is further connected to the spline sleeve on the coupling 330. Exemplarily, the rotary drive component 320 and the drive component fixing frame 340 are connected in a detachable manner, and the drive component fixing frame 340 and the main support 200 can also be detachably connected.

[0050] Furthermore, one end of the drive component mounting bracket 340 is provided with a perforated flange, which has bolt mounting holes for fixed connection with the main support 200. The other end of the drive component mounting bracket 340 is provided with a circular flange, which has bolt mounting holes for fixed connection with the rotary drive component 320. Figure 10 and Figure 11 As shown, the left and right ends of the drive component mounting bracket 340 are respectively provided with a plum blossom flange and a circular flange. Both the plum blossom flange and the circular flange are provided with mounting holes. At this time, the plum blossom flange and the circular flange are fixedly connected to the main bracket 200 and the rotary drive component 320 respectively.

[0051] In some embodiments, the main support 200 includes a first inclined portion 210, a horizontal portion 220, a second inclined portion 230, and a third inclined portion 240 connected in sequence. The first inclined portion 210 and the second inclined portion 230 at both ends of the horizontal portion 220 slope outwards and gradually upwards, respectively. The third inclined portion 240 slopes outwards and gradually upwards from the end of the second inclined portion 230 away from the horizontal portion 220. In this case, the shaft hole of the main support 200 is specifically located on the third inclined portion 240, such as... Figure 4 , Figure 5 and Figure 6 As shown, the first inclined portion 210 and the second inclined portion 230 on the main support 200 are both provided with connecting lugs for connecting to the main body of the tracked mixer truck. Furthermore, as shown... Figure 1 As shown, the mixing tank 100 is specifically located above the main support 200.

[0052] Furthermore, the angle between the first inclined portion 210 and the horizontal portion 220 is greater than 120 degrees; and / or, the angle between the horizontal portion 220 and the second inclined portion 230 is greater than 120 degrees; and / or, the angle between the second inclined portion 230 and the third inclined portion 240 is greater than 120 degrees. Figure 4 In the main support 200 shown, the angle between the first inclined portion 210 and the horizontal portion 220, the angle between the horizontal portion 220 and the second inclined portion 230, and the angle between the second inclined portion 230 and the third inclined portion 240 are all approximately 160 degrees.

[0053] Furthermore, to further facilitate the positioning of each component, the coupling 330 and / or the drive component mounting bracket 340 may also be provided with a stop positioning part. When the coupling 330 is connected to the main rotary bearing 310, the stop positioning part on the coupling 330 can be disposed within the shaft hole of the main rotary bearing 310; while when the drive component mounting bracket 340 is connected to the main support 200, the stop positioning part on the drive component mounting bracket 340 can specifically be disposed within the shaft hole of the main support 200.

[0054] In the above-described embodiment of the present invention, the mixing tank drive fixing structure is installed by first aligning the main rotary bearing 310, coupling 330, and fixing mounting holes of the fixing connecting plate 110 on the mixing tank 100. Then, bolts are used to connect the inner ring of the main rotary bearing 310, coupling 330, and fixing connecting plate 110 into a single unit. Next, the fixing mounting holes on the outer ring of the main rotary bearing 310 are aligned with the fixing mounting holes on the main support 200. Then, bolts are used to fix the main rotary bearing 310 to the main support 200. The outer ring of the main rotary bearing 310 is fixed on the main support 200, and the inner ring of the main rotary bearing 310 is connected to the mixing tank 100. Therefore, the mixing tank 100 can rotate with the inner ring of the main rotary bearing 310. Furthermore, the drive component mounting bracket is fixed to the other side of the main support 200, and the output shaft of the rotary drive component 320 passes through the shaft hole of the drive component mounting bracket and the shaft hole of the main support 200, and is connected to the shaft hole of the coupling 330; thus, when the output shaft of the rotary drive component 320 rotates, the mixing tank 100 can be driven to rotate through the coupling 330, the inner ring of the main rotary bearing 310 and the fixed connecting plate 110 at the end of the mixing tank 100.

[0055] As can be seen from the above, the mixing tank drive fixing structure of this application can more conveniently and economically realize the fixing and rotation drive of the mixing tank. It can not only realize the rapid and efficient assembly of the mixing tank, but also minimize production costs, improve work efficiency, and extend the service life of the whole machine.

[0056] Accordingly, this utility model also provides a tracked transport vehicle, which includes the front loading bucket boom fixing structure of the tracked transport vehicle as described in any of the above embodiments.

[0057] In this invention, features described and / or illustrated for one embodiment may be used in the same or similar manner in one or more other embodiments, and / or combined with or in place of features of other embodiments.

[0058] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
