[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Combine the following Figures 1 to 3 A vehicle roof crossing structure and an operating machine provided in an embodiment of the utility model are described.

[0026] A roof wire passing structure provided in this embodiment includes a curved pipe 1, which is arranged on the automobile roof 2. The curved pipe 1 is integrally connected to the automobile roof 2. The first end of the curved pipe 1 is connected to the lead hole of the automobile roof 2. The curved pipe 1 is connected to the interior of the automobile through the lead hole. The second end of the curved pipe 1 corresponds to the automobile roof 2, that is, the second end port of the curved pipe 1 corresponds to the automobile roof 2, so as to prevent rainwater from all directions above from entering the curved pipe 1.

[0027] It can be seen from the above scheme that the wire harness is led out from the interior of the car through the curved pipe 1 set on the car roof 2, and the wire harness is constrained in the curved pipe 1, which limits the movement of the wire harness and reduces the wear of the wire harness; by integrally connecting the curved pipe 1 and the car roof 2, the problem of unreliable sealing caused by the car roof 2 opening the wire hole 31 and connecting the curved pipe 1 in the traditional technology is avoided. Since the second end of the curved pipe 1 corresponds to the car roof 2, it can prevent external rainwater from all directions above from entering the curved pipe 1 and entering the interior of the car, thereby playing a good protective role.

[0028] In this embodiment, a sealing plug 3 is provided at the second end of the elbow 1. A wire passing hole 31 is provided on the sealing plug 3. The inner wall of the wire passing hole 31 is in close contact with the outer side of the wire harness.

[0029] With such arrangement, the waterproof and dustproof effect of the bent pipe 1 is further improved through the sealing plug 3, and the setting of the bent pipe 1 is prevented from affecting the air tightness of the vehicle. Since the wiring harness is tightly fixed in the sealing plug 3, while the wiring harness can be smoothly led out of the bent pipe 1, the stability of the wiring harness is also guaranteed, and the wear caused by the movement of the wiring harness at the second end of the bent pipe 1 is avoided.

[0030] The sealing plug 3 is detachably connected to the second end of the elbow 1, and the sealing plug 3 can be installed in the elbow 1 by threaded connection, plug-in connection, etc.

[0031] Furthermore, the bent pipe 1 is integrally welded to the automobile roof 2. By integrally welding the bent pipe 1 to the automobile roof 2, compared with the prior art, the gluing and sealing process is eliminated, the vehicle top sealing process is reduced, and the problem of water leakage caused by failure of the sealing of the roof lead hole is avoided.

[0032] In this embodiment, Figures 1 to 3 As shown, the elbow 1 is a U-shaped structure, and the elbow 1 includes an inlet segment 11, a transition segment 12 and an outlet segment 13. The transition segment 12 is connected between the inlet segment 11 and the outlet segment 13. The free end of the inlet segment 11 is connected to the automobile roof 2, and the free end of the outlet segment 13 is provided with a sealing plug 3; Figure 1 As shown, the elbow 1 is connected to the automobile roof 2 in an inverted U shape, the transition section 12 is an arc-shaped structure, and the two ends of the transition section 12 are smoothly connected to the inlet section 11 and the outlet section 13 respectively.

[0033] Reference Figure 1 In this embodiment, the central axis of the outlet section 13 is perpendicular to the upper surface of the automobile roof 2, that is, the second end of the elbow 1 is arranged downward and directly opposite the automobile roof 2; such an arrangement can prevent water flows in directions other than vertically upward, such as vertically downward and horizontal directions, from invading the vehicle, and compared with the prior art, the waterproof effect is improved, and the sealing plug 3 also ensures the airtightness of the elbow 1.

[0034] Reference Figure 2 In other embodiments, there is an angle a between the central axis of the outlet section 13 and the upper surface of the automobile roof 2, and the angle a is less than 90°, for example, 45°<a<90°, that is, the second end of the curved pipe 1 is tilted downward, so that water flows in other directions except upward along this angle can be prevented from intruding into the vehicle, which improves the waterproof effect compared to the prior art.

[0035] like Figure 1 As shown, the central axis of the incoming line segment 11 is perpendicular to the upper surface of the automobile roof 2, which is convenient for leading the wiring harness in the car outward. Of course, the incoming line segment 11 can also be connected to the automobile roof 2 in an inclined manner.

[0036] Reference Figure 1 The embodiment of the utility model further provides a working machine, including a cab, wherein the cab is provided with the above-mentioned roof crossing structure. Since the working machine has the above-mentioned roof crossing structure, it has all the advantages of the roof crossing structure, which will not be described in detail here.
