[0032] The technical solutions of the present application will be clearly and completely described below with reference to the drawings.

[0033] Please refer to Figure 1 , which is a schematic structural diagram of a gearbox 130 shown in an embodiment of the present application. A gearbox 130 includes a housing 2, a connecting member 3, and a guide rail 4.

[0034] The housing 2 (please refer to Figure 2 ) is a cuboid structure, having a first surface 21, a second surface 22, and a third surface 23. The first surface 21 is respectively connected to the second surface 22 and the third surface 23. The second surface 22 is respectively connected to the third surface 23 and the fourth surface. The third surface 23 is respectively connected to the first surface 21 and the second surface 22. In this embodiment, the first surface 21 includes upper and lower surfaces, which are respectively a first upper surface 21a and a second upper surface 21b. The second surface 22 includes left and right surfaces, which are respectively a first side surface 22a and a second side surface 22b arranged oppositely. The third surface 23 includes front and rear surfaces, which are respectively a third side surface 23a and a fourth side surface 23b arranged oppositely.

[0035] Among them, the first surface 21 and the second surface 22 are arranged intersectingly, and there is an included angle between the first surface 21 and the second surface 22. The included angle can be an acute angle, a right angle, or an obtuse angle. In this embodiment, the included angle is a right angle.

[0036] The connecting member 3 is provided on the first surface 21 of the housing 2. The connecting member 3 has a plate-like structure or a structure similar to a flange, and it can be integrally formed with the housing 2 or fixed to the housing 2 by means of bolt connection, welding, etc. In this embodiment, the connecting member 3 is provided on the first upper surface 21a for hanging. To increase the strength of the connecting member 3, reinforcing ribs 31 are provided on the connecting member 3.

[0037] The guide rail 4 is provided on the second surface 22 of the housing 2. Among them, when the connecting member 3 is moved, the connecting member 3 can move the housing 2 along the length direction of the guide rail 4, that is, the housing 2 can be moved upward or downward.

[0038] There are two guide rails 4, which are respectively located on the first side surface 22a and the second side surface 22b. The two guide rails 4 are parallel to each other, and the length directions of the two guide rails 4 are arranged in the same direction, which is used to limit the movement of the gear box 130 in the left and right directions, so that the gear box 130 does not produce yaw.

[0039] Please refer to Figure 2 , which is a partial structural schematic diagram of the continuous excavator 100 shown in an embodiment of the present application. A continuous excavator 100 includes a gear box 130 and a second driving member 120. The second driving member 120 is provided on the truss 110 (please refer to Figure 3 ) and is connected to the connecting member 3 for moving the gear box 130.

[0040] The second driving member 120 can be components such as a hydraulic cylinder, an electric cylinder, a pneumatic cylinder, a motor screw rod or a motor pulley. In this embodiment, the second driving member 120 is a hydraulic cylinder, and the telescopic rod of the hydraulic cylinder is fixedly connected to the connecting member 3 by means of flange connection, bolt connection, etc., so as to drive the connecting member 3 to move up and down.

[0041] Please refer to Figure 3 , which is a partial structural schematic diagram of the continuous excavator 100 shown in an embodiment of the present application. The continuous excavator 100 includes a truss 110, and the gear box 130 (please refer to Figure 1 ) is installed inside the truss 110. The truss 110 is provided with guide rail grooves 111 that match the guide rails 4 (please refer to Figure 1 ). In this embodiment, the guide rail grooves 111 are rectangular grooves, and there are two correspondingly. Therefore, the two guide rails 4 of the gear box 130 can be respectively embedded in the two guide rail grooves 111, so that the gear box 130 does not produce yaw.

[0042] In this embodiment, the second driving member 120 can drive the connecting member 3 to rise or fall, and the connecting member 3 drives the housing 2 to rise or fall along the guide rail 4 and the guide rail groove 111, so that the position and depth of excavation can be controlled by the second driving member 120. Therefore, in this embodiment, the gearbox 130 can be moved in a preset direction, that is, the length direction of the guide rail 4, and the gearbox 130 is relatively flexible, so as to adapt to the working conditions of the continuous excavator 100 for construction engineering.

[0043] Please refer to Figure 4 , which is a schematic structural diagram of the gearbox 130 shown in an embodiment of the present application. Please refer to Figure 5 , which is Figure 4 a cross-sectional view taken along the A-A direction of the present application. The gearbox 130 includes a first shaft 7, a second shaft 8, and a third shaft 9; the first shaft 7 is disposed inside the housing 2; the second shaft 8 is disposed inside the housing 2 and is in transmission connection with the first shaft 7; the third shaft 9 is disposed inside the housing 2 and is in transmission connection with the second shaft 8.

[0044] The gearbox 130 includes a first gear 71, a second gear 81, and a third gear 91; the first gear 71 is sleeved on the first shaft 7; the second gear 81 is sleeved on the second shaft 8; the third gear 91 is sleeved on the third shaft 9; wherein, the second gear 81 meshes with the first gear 71 and the third gear 91 at the same time.

[0045] In this embodiment, the first gear 71 is a small gear for input, the third gear 91 is a large gear for output, and the second gear 81 is an idler gear. By adding the second gear 81 and the second shaft 8 in this embodiment, the center distance between the first shaft 7 and the third shaft 9 is increased, so as to adapt to the working conditions of the continuous excavator 100 for construction engineering.

[0046] The axis of the first shaft 7 and the axis of the third shaft 9 form a first plane Q1, and the second shaft 8 is disposed outside the first plane Q1. Then, the axes of the first shaft 7, the second shaft 8, and the third shaft 9 are not in the same plane, and the first plane Q1 is inclined relative to the first surface 21, so that there is a certain angle between the first plane Q1 and the first upper surface 21a. Thus, the height of the gearbox 130 can be reduced while meeting the requirement of the center distance between the first shaft 7 and the third shaft 9, so that the gearbox 130 can be made more flat, reducing the space occupied by the gearbox 130, and enabling it to be installed inside a narrow space.

[0047] A first bearing 711 is sleeved at each end of the first shaft 7. A first mounting hole 24 for mounting the first bearing 711 is defined on each of the third side surface 23a and the fourth side surface 23b. The first shaft 7 extends outside the housing 2 through the first mounting hole 24 on the third side surface 23a. A first transparent cover 241 is provided on one side of the housing 2, covering the first mounting hole 24 on the third side surface 23a. A first blind cover 242 is provided on one side of the housing 2, covering the first mounting hole 24 on the fourth side surface 23b.

[0048] A second bearing 811 is sleeved at each end of the second shaft 8, and a second mounting hole 25 is provided on each of the third side surface 23a and the fourth side surface 23b for mounting the second bearing 811. The housing 2 is provided with a second cover 251 on each side of the two second mounting holes 25.

[0049] A third bearing 911 is fitted onto each end of the third shaft 9. A third mounting hole 26 for mounting the third bearing 911 is provided on each of the third side surfaces 23a and 23b. The third shaft 9 extends out of the housing 2 through the third mounting hole 26 on the third side surface 23a. A third transparent cover 261 is provided on one side of the housing 2, covering the third mounting hole 26 on the third side surface 23a. A third blind cover 262 is provided on one side of the housing 2, covering the third mounting hole 26 on the fourth side surface 23b.

[0050] Please refer to Figure 6 , which is a schematic structural diagram of a gearbox 130 according to one embodiment of the present application. A flange seat 27 is provided on the third side surface 23a, located at the first mounting hole 24. A first drive member 5 is detachably connected to the flange seat 27. The first drive member 5 is in driving connection with the first shaft 7 to drive the first shaft 7 to rotate. The first drive member 5 may be a hydraulic motor, an electric motor, or other component. In this embodiment, the first drive member 5 is a hydraulic motor.

[0051] The third shaft 9 is connected to the sprocket 6 in a transmission manner. The sprocket 6 is used to install the excavation tool chain.

[0052] During an operation, the first driving member 5 drives the first shaft 7 to rotate, the first shaft 7 drives the first gear 71 to rotate, the rotation of the first gear 71 drives the second gear 81 and the third gear 91 to rotate, the rotation of the third gear 91 drives the third shaft 9 to rotate, the third shaft 9 drives the sprocket 6 to rotate, and the sprocket 6 drives the excavation tool chain, thereby performing excavation work.

[0053] Among them, the sprocket 6 and the first driving member 5 are both located on the same side of the third side surface 23a, so the gear box 130 has a more compact structure, which can make the gear box 130 flatter, reduce the space occupied by the gear box 130, and enable it to be installed in a narrow space.

[0054] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
