[0035] A scraper loader using a horizontal cable drum in the present application, such as Figure 1 to Figure 4 As shown, it includes a frame 1, a power system 2, and a cable drum assembly 3, wherein the cable drum assembly 3 is horizontal, and its rotation axis is perpendicular to the driving road surface, and the cable drum assembly 3 is located in the inner cavity of the frame 1, and the frame 1 forms a protective skeleton of the cable drum assembly 3, and the cable drum assembly 3 is driven to rotate by the power system 2. It also includes a steering rocker arm assembly 4, and its steering is controlled by a steering electro-hydraulic system. The steering rocker arm assembly 4 can not only guide the cable to the cable drum assembly 3, but also can turn with the scraper under the control of the steering electro-hydraulic system to reduce the tension of the cable.

[0036] The steering rocker arm assembly 4 is located below the cable drum assembly 3, and a cable guide wheel 41 and a cable support wheel 44 are provided at one end of the steering rocker arm assembly 4 away from the cable drum assembly 3. The cable is guided by the cable guide wheel 41 and wound onto the cable drum assembly 3. The cable support wheel 44 is located outside the cable guide wheel 41. The rotation axis of the cable support wheel 44 is perpendicular to the rotation axis of the cable guide wheel 41. The cable support wheel 44 is used to reduce the wear during the cable retraction and release process. A pair of cable guide wheels 41 are preferably provided and arranged side by side. There is a gap between the cable guide wheel 41 and the cable drum assembly 3 to avoid the influence of mutual rotation due to too close distance.

[0037] like Figure 6 , Figure 7 As shown, a protrusion is fixedly connected to one end of the steering rocker arm assembly 4 close to the cable drum assembly 3, and the protrusion is rotatably connected to the telescopic assembly 5. The telescopic assembly 5 includes a movable rod and a fixed rod. The steering electro-hydraulic system drives the movable rod to extend and retract along the fixed rod, thereby driving the steering rocker arm assembly 4 to steer.

[0038] More specifically, the raised portion includes a first raised portion 42 and a second raised portion 43 arranged side by side with the first raised portion 42. Correspondingly, the telescopic assembly 5 includes a first telescopic assembly and a second telescopic assembly. One end of the first telescopic assembly is movably connected to the side of the bracket 1, and the other end is movably connected to the first raised portion 42; similarly, one end of the second telescopic assembly is movably connected to the second side of the bracket 1, and the other end is movably connected to the second raised portion 43.

[0039] like Figure 7As shown, the first telescopic assembly includes a first movable rod 51 and a first fixed rod 52 sleeved on the first movable rod 51, the first movable rod 51 can be telescopic along the first fixed rod 52, and the first protrusion 42 is movably connected to the first movable rod 51; the second telescopic assembly includes a second movable rod 53 and a second fixed rod 54 sleeved on the second movable rod 53, the second movable rod 53 can be telescopic along the second fixed rod 54; the second protrusion 43 is movably connected to the second movable rod 53. When the scraper turns, the steering electro-hydraulic system works synchronously, driving the first movable rod 51 and the second movable rod 53 to retract and extend respectively, thereby driving the steering rocker arm assembly 4 to rotate synchronously to reduce the tension of the cable.

[0040] like Figure 4 , Figure 5 As shown, the power system 2 includes a slip ring box 21 and a motor 22. The slip ring box 21 is used to record the number of revolutions of the motor shaft. At the same time, the motor 22 is controlled to rotate or stop by the slip ring box 21. The motor 22 can rotate forward or reverse. A rotating shaft is provided inside the slip ring box 21. The rotating shaft of the slip ring box 21 is connected to the motor shaft of the motor 22, and can be connected specifically through a coupling 6.

[0041] The cable drum 3 includes two drums and a winding portion 33. The two drums are respectively a first disk 31 and a second disk 32. The second disk 32 is located directly below the first disk 31. The two drums are respectively fixedly connected to both ends of the winding portion 33. The inner cavity of the winding portion 33 is fixedly connected with a first reinforcing plate 331 and a second reinforcing plate 332 located above the first reinforcing plate 331. A through hole is provided between the first reinforcing plate 331 and the second reinforcing plate 332 for placing the coupling 6.

[0042] A scraper loader using a horizontal cable drum in the present application further includes a mounting base 7, which is preferably a hollow circular ring, and is bolted to the bottom plate of the bracket 1. The mounting base 7 is connected to an external slewing support 34 on the outside, and is connected to an internal slewing support 35 on the inside. The outer ring of the external slewing support 34 is bolted to the steering rocker arm assembly 4, and the inner ring of the external slewing support 34 is bolted to the steering rocker arm assembly 4. The steering rocker arm assembly 4 is rotatably connected to the mounting base 7 through the external slewing support 34, that is, the steering rocker arm assembly 4 can rotate relative to the mounting base 7. The outer ring of the internal slewing support 35 is bolted to the mounting base 7, and the inner ring is bolted to the first reinforcing plate 331, so the first reinforcing plate 331 and the entire cable drum 3 are rotatably connected to the mounting base 7 through the internal slewing support 35, that is, the cable drum 3 can rotate relative to the mounting base 7.

[0043] The motor 22 is bolted to the mounting base 7 via the mounting plate 221 , and the slip ring box 21 is bolted to the second reinforcing plate 332 via the flange 23 , and the flange 23 is fixedly connected to the internal rotating shaft of the slip ring box 21 .

[0044] The slip ring box 21 controls the motor 22 to rotate. Through the coupling 6, the motor 22 drives the rotating shaft inside the slip ring box 21 together with the flange 23 to rotate, and the flange drives the second reinforcing plate 332 to rotate, thereby realizing the rotation of the entire cable reel assembly 3.

[0045] Since the mounting base 7 can be separated from the vehicle frame 1 by removing the bolts, the components connected to the mounting base 7 can be removed from the vehicle frame 1 together, such as the power system 2, the cable drum assembly 3 and the steering rocker arm assembly 4 can be separated from the vehicle frame 1 together. The advantage is that after removal, they can be moved to the ground, and there is a larger operating space to inspect or replace the components of the power system 2, the cable drum assembly 3 and the steering rocker arm assembly 4.

[0046] In addition, when the scraper is in a transport state or a vehicle maintenance, repair, or assembly state, the cable drum assembly 3 needs to be relatively still to prevent rotation from causing damage to other parts or accidental injuries. Therefore, the scraper is also provided with a drum locking device 8, which is located on the upper surface of the frame 1 and can be inserted into the first disc 31 from above to make the cable drum assembly 3 relatively still.

[0047] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
