Description

Technical Field

[0001] The present invention relates to the technical field of conductor guide devices, and in particular to a conductor guide device, a rotary mechanism and an operating machine. Background Art

[0002] With the development of diversified applications of operating machinery, the structure of operating machinery tends to be more refined, humanized, and convenient for operation and maintenance.

[0003] Taking the fire truck as an example, the high-rise jet fire truck is composed of a folding and telescopic arm mechanism, an electric remote-controlled fire cannon, a tank body and a Class II chassis. The boom is the basic arm, and an electric remote-controlled fire cannon is installed at the end of the arm. Firefighters use the electric remote-controlled fire cannon to flexibly spray, spray water or spray foam from multiple angles in the air to extinguish general fires.

[0004] At present, the turntable electric control cabinet of high-pressure fire trucks is basically installed on the turntable and moves synchronously with the turntable. The wire harness entering the turntable electric control cabinet will also be driven by the electric control cabinet to move together. The wire harness between the chassis and the electric control cabinet must be a movable wire harness. The wire harness passes from the chassis electric control cabinet through the chassis to the turntable and finally connects to the turntable electric control cabinet. The wire harness in the turntable is freely suspended in the air and fixed together with the hydraulic pipe.

[0005] However, when the turntable rotates, the wiring harness will move with the turntable's electrical control cabinet. At this time, the wiring harness will be entangled on the gun water outlet pipe in the middle of the turntable due to the rotation of the turntable, and because the wiring harness is fixed together with the hydraulic pipe, the hydraulic pipe is at risk of being squeezed, pulled and broken. Summary of the invention

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0039] Combine the following Figures 1 to 6 The present invention describes a guide wire device, a cab and a working machine.

[0040] like Figure 1 As shown, the present invention provides a wire guiding device for guiding a cable 100 passing through a rotating end and a fixed end; the device comprises an upper guide ring 1 and a lower guide ring 3, the upper guide ring 1 is provided with an upper cable guide tube 2 for fixing the cable 100 and allowing the cable 100 to pass through; the lower guide ring 3 is provided with a lower cable guide tube 4 for the cable 100 to pass through; one of the upper guide ring 1 and the lower guide ring 3 is connected to the rotating end, and the other is connected to the fixed end; and an enclosure space for accommodating the cable 100 is formed between the upper guide ring 1 and the lower guide ring 3.

[0041] The wire guide device provided by the present invention is provided with an upper guide ring 1 and a lower guide ring 3. The upper guide ring 1 is provided with an upper cable guide tube 2 for fixing the cable 100 and allowing the cable 100 to pass through, and the lower guide ring 3 is provided with a lower cable guide tube 4 for the cable 100 to pass through; one of the upper guide ring 1 and the lower guide ring 3 is connected to the rotating end, and the other is connected to the fixed end, and an enclosure space for accommodating the cable 100 is formed between the upper guide ring 1 and the lower guide ring 3. When the rotating end drives the cable 100 to rotate, it will drive the cable 100 to move in the enclosure space, prevent the cable 100 from escaping from the enclosure space, and prevent the cable 100 from being entangled in other pipelines, so that the cable 100 can follow the rotating end to make a 360° reciprocating motion.

[0042] like Figure 1 As shown, generally, the upper guide ring 1 and the lower guide ring 3 can be understood as circular rings. When the rotating end drives the cable 100 to rotate, the cable 100 can reciprocate in the enclosed space to reduce the resistance to movement.

[0043] It should be noted that the enclosure space is not a closed space, that is, the upper guide ring 1 and the lower guide ring 3 are not connected in structure, and the two are relatively independent structures. The reason is that during the working process, the upper guide ring and the lower guide ring have relative movement to prevent the upper guide ring 1 and the lower guide ring 3 from being worn during the working process.

[0044] That is to say, in the embodiment of the present invention, there is a spacing between the upper guide ring 1 and the lower guide ring 3 to avoid the contact between the upper guide ring 1 and the lower guide ring 3, which is easy to generate friction during the rotation process, and the spacing needs to be smaller than the minimum outer diameter of the cable 100, which can ensure that the cable 100 will not escape from the enclosure space during the movement and prevent it from being entangled in the water pipe. Since there are multiple usage scenarios during use, multiple cables may be used at the same time, or a single cable may be used alone. In order to prevent cables with smaller outer diameters from escaping the track from the spacing, the size of the spacing needs to be set to be smaller than the minimum outer diameter of the cable. When the cable 100 is the cable 100 used on a fire truck, assuming the spacing is d, then 2mm≤d≤5mm.

[0045] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, the upper guide ring 1 includes a first upper guide ring 11 and a second upper guide ring 12, and the two ends of the first upper guide ring 11 and the second upper guide ring 12 are respectively connected to form a closed loop structure; and an upper cable guide 2 is provided on one of the first upper guide ring 11 and the second upper guide ring 12; and the first upper guide ring 11 and the second upper guide ring 12 are both provided with a first mounting plate 13 for mutual connection. The upper guide ring 1 is divided into two parts, the first upper guide ring 11 and the second upper guide ring 12, which facilitates the installation and maintenance of the conductor device in a narrow space such as a turret.

[0046] Of course, the upper guide ring 1 can also include a third upper guide ring, a fourth upper guide ring..., that is, when it has multiple components, it is only necessary for the multiple components to form a closed loop, that is, the first upper guide ring 11, the second upper guide ring 12, the third upper guide ring, the fourth upper guide ring... are connected end to end to form a closed loop. In practical applications, it usually includes two or three parts, which can facilitate the installation and maintenance of the wire device.

[0047] When the upper guide ring 1 has multiple components, the upper fairlead 2 can be arranged on any component. The upper fairlead 2 is arranged vertically. The upper fairlead 2 is usually in a round tube shape, and the axis of the upper fairlead 2 is perpendicular to the horizontal plane.

[0048] like Figure 2As shown, in order to fix the cable 100 on the upper fairlead 2, at least two tie fixing holes 21 are usually opened on the side wall of the upper fairlead 2. When fixing the cable 100, the cable 100 is fixed on the upper fairlead 2 by passing the tie through the tie fixing hole 21. The number of the tie fixing holes 21 can also be three, four... Two tie fixing holes 21 at appropriate positions can be selected according to the use requirements.

[0049] Since an enclosure space needs to be formed between the upper guide ring 1 and the lower guide ring 3, the opposite surface of one of the upper guide ring 1 and the lower guide ring 3 must have a certain groove for accommodating the cable 100. Generally speaking, in order to reduce the friction between the cable 100 and the upper guide ring 1 or the lower guide ring 3 during the rotation process, a structure that is conducive to forming an enclosure space is provided on the opposite sides of the upper guide ring 1 and the lower guide ring 3.

[0050] Specifically, Figure 2 As shown, the cross section of the upper guide ring 1 can be designed as a semicircular shape with an opening downward, and the upper guide ring 1 can be fixed to the rotating end. When used in a fire truck, the upper guide ring 1 is fixed to the turntable and rotates with the turntable. Since the cables 100 are mostly circular, the cross section of the upper guide ring 1 is set to be semicircular so that the shape of the upper guide ring 1 matches the shape of the cable 100, which can minimize the possibility of friction between the cable 100 and the side wall of the upper guide ring 1. The inner diameter of the semicircular cross section of the upper guide ring 1 is larger than the outer diameter of the cable 100.

[0051] In addition, if Figure 3 As shown, in an embodiment of the present invention, the lower guide ring 3 may include a first lower guide ring 31 and a second lower guide ring 32, and the two ends of the first lower guide ring 31 and the second lower guide ring 32 are respectively connected to form a closed loop structure; and a lower cable guide pipe 4 is provided on one of the first lower guide ring 31 and the second lower guide ring 32; that is, the cable 100 enters from the upper cable guide pipe 2, and is led out from the lower cable guide pipe 4 after making a circle in the enclosure space.

[0052] like Figure 4 As shown, both ends of the first lower guide ring 31 and the second lower guide ring 32 are provided with a second mounting plate 33 for connecting with each other. Figure 3 and Figure 4 As shown, the lower guide ring 3 is divided into a first lower guide ring 31 and a second lower guide ring 32, which facilitates the installation and maintenance of the conductor device in a narrow space such as a turret.

[0053] Of course, the lower guide ring 3 can also include a third lower guide ring, a fourth lower guide ring..., that is, when it has multiple components, it is only necessary for the multiple components to form a closed loop, that is, the first lower guide ring 31, the second lower guide ring 32, the third lower guide ring, the fourth lower guide ring... are connected end to end to form a closed loop. In practical applications, it usually includes two or three parts, which can facilitate the installation and maintenance of the wire device.

[0054] When the lower guide ring 3 has multiple components, the lower fairlead 4 can be set in any component. The lower fairlead 4 can usually be a circular tube. The axis of the lower fairlead 4 is perpendicular to the horizontal plane. The lower fairlead 4 extends to the bottom of the lower guide ring 3.

[0055] In the embodiment of the present invention, the lower fairlead 4 is provided with fairlead grooves 6 on both sides along the extension direction of the lower guide ring 3; that is, the lower guide ring 3 is provided with fairlead grooves 6 on both sides of the lower fairlead 4, and the cable 100 is in a drooping state when in a free state, and when the rotating end rotates, the cable 100 is more easily inserted into the lower guide ring 3 due to the provision of the fairlead grooves 6. Moreover, the diameter of the lower fairlead 4 is larger than that of the upper fairlead 2, in order to prevent the cable 100 from being worn due to friction with the edge of the lower fairlead 4 due to vibration when the fire truck is working.

[0056] In the embodiment of the present invention, in order to prevent the cable 100 from getting stuck and worn due to friction during movement, a rolling mechanism 5 for reducing the friction generated by the movement of the cable 100 is provided at the bottom of the lower guide ring 3. During the movement of the cable 100, the rolling of the rolling mechanism reduces the friction generated by the movement of the cable 100.

[0057] like Figure 3 , Figure 4 and Figure 5 As shown, in the embodiment of the present invention, the rolling mechanism 5 includes a plurality of rollers 51, and a plurality of roller grooves 52 are provided on the lower guide ring 3. The rollers 51 are arranged in the roller grooves 52 in a one-to-one correspondence, and the two ends of the rollers 51 are limited by the limit pins 53 to prevent them from slipping. In other words, the rollers 51 are arranged on the lower guide ring 3 for horizontal rotation. During the movement of the cable 100, the rolling of the rollers 51 reduces the sliding friction generated by the movement of the cable 100. At the same time, the gap of the roller grooves 52 can quickly drain the accumulated water when it rains or when the fire truck pumps water, so as to prevent the accumulated water from corroding the cable 100 and the lower guide ring 3.

[0058] Among them, in order to facilitate the opening of the roller groove 52, a roller 51 is set, and the lower guide ring 3 is set to have a semi-arc I-shaped groove in cross section. The top of the lower guide ring 3 has a groove for accommodating the cable 100, and the shape of the groove is approximately a U-shaped groove, and the bottom has a structure for opening the roller groove 52.

[0059] In an embodiment of the present invention, Figure 2 As shown, at least two first mounting feet 7 are provided on the top of the upper guide ring 1; Figure 4As shown, at least two second mounting feet 8 are provided at the bottom of the lower guide ring 3. The positions of the first mounting feet 7 and the second mounting feet 8 correspond to the positions of the rotating end and the fixed end. When used in a fire truck, the upper guide ring 1 is fixedly connected to the turntable of the fire truck, that is, the upper guide ring 1 rotates with the rotating end, and the upper guide ring 1 is fixedly connected to the turntable through the first mounting feet 7; the lower guide ring 3 is fixedly connected to the turret of the fire truck (the turret is fixed during operation).

[0060] Among them, the upper fairlead 2 and the upper guide ring 1 can be connected as a whole or fixedly connected. When a fixed connection is adopted, welding can usually be used; the lower fairlead 4 and the lower guide ring 3 can be connected as a whole or fixedly connected. When a fixed connection is adopted, welding can usually be used.

[0061] In addition, the material of the conductor device can be an aluminum profile or steel, and needs to have a certain strength and rigidity to meet the use requirements.

[0062] In summary, the wire guide device provided by the present invention includes an upper guide ring 1 and a lower guide ring 3, the upper guide ring 1 includes a first upper guide ring 11 and a second upper guide ring 12; the lower guide ring 3 includes a first lower guide ring 31, a second lower guide ring 32 and a roller 51, and the wire guide device is made of aluminum profile or steel.

[0063] The first upper guide ring 11 and the second upper guide ring 12 are both semicircular, and the first upper guide ring 11 and the second upper guide ring 12 are connected end to end through the first mounting plate 13 to form a closed loop; the first upper guide ring 11 and the second upper guide ring 12 are installed in combination, which can be convenient for installation and maintenance. The first upper guide ring 11 and the second upper guide ring 12 are fixed to the rotating end, fixed to the turntable, and rotate with the turntable; one of the first upper guide ring 11 and the second upper guide ring 12 is provided with an upper cable guide 2, and the cable 100 is fixed on the upper cable guide 2, and the bottom side of the first upper guide ring 11 and the second upper guide ring 12 has a space for accommodating the cable 100. Four cable tie fixing holes 21 are opened on the upper cable guide 2, and the cable tie fixing holes 21 are used to fix the cable 100, and the cable 100 is first fixed on the upper cable guide 2.

[0064] The cross-section of the first lower guide ring 31 and the second lower guide ring 32 is a semi-arc I-shaped groove design, which is fixed on the turret and cannot move; the first lower guide ring 31 and the second lower guide ring 32 are installed in combination, which can be convenient for installation and maintenance. One of the first lower guide ring 31 and the second lower guide ring 32 is provided with a lower cable guide tube 4, and the diameter of the lower cable guide tube 4 is larger than the diameter of the upper cable guide tube 2. This design is to prevent the cable 100 from being worn due to friction with the edge of the lower cable guide tube 4 due to vibration during operation.

[0065] At the same time, cable guide grooves 6 are designed on both sides of the lower cable guide tube 4. When the turntable rotates, the cable 100 can move into the first lower guide ring 31 or the second lower guide ring 32 more easily. In order to prevent the cable 100 from getting stuck and worn due to friction during movement, roller grooves 52 are opened at the bottom of the first lower guide ring 31 and the second lower guide ring 32, and rollers 51 are installed on the roller grooves 52. During the movement of the cable 100, the rollers 51 roll to reduce the friction generated by the movement of the cable 100. At the same time, the gap of the roller groove 52 can quickly drain the accumulated water when it rains or when the fire truck pumps water, preventing the accumulated water from corroding the cable 100 and the guide ring.

[0066] After the upper guide ring 1 and the lower guide ring 3 are fixed on the turntable and the turret respectively, the spacing between them is 2mm-5mm, forming an enclosure space. This assembly spacing ensures that the cable 100 will not fall out of the wire device during movement and prevent it from being entangled in the water pipe.

[0067] Finally, it should be noted that Figure 6 As shown, when the conductor device is in use, the cable 100 is first led out from the rotating end such as a turntable, and the cable 100 is fixed on the upper cable guide pipe 2. After the cable 100 wraps around the enclosure space, it naturally hangs down from the lower cable guide pipe 4 and connects to the fixed end such as a turret.

[0068] In the wire guide device provided by the present invention, the cable 100 is fixed on the upper cable guide tube 2 on the upper guide ring 1, and when the rotating end rotates, the cable 100 is driven to move together; the cable 100 is located in the enclosure space enclosed between the upper guide ring 1 and the lower guide ring 3; the lower guide ring 3 is fixed at the fixed end, and the lower guide ring 3 is fixed; the upper guide ring 1 drives the cable 100 to perform 360° reciprocating motion in the lower guide ring 3. Since the spacing between the upper guide ring 1 and the lower guide ring 3 is smaller than the maximum outer diameter of the cable 100, the cable 100 can be prevented from falling out during the movement, ensuring that the cable 100 is always in the enclosure space during the movement.

[0069] The rotating mechanism provided by the present invention is described below. The rotating mechanism described below and the wire guide device described above can be referred to each other.

[0070] Another aspect of the present invention is to provide a swivel mechanism, comprising the guide wire device as described above.

[0071] In the embodiment of the present invention, when the slewing mechanism is used in a fire truck, the slewing mechanism includes a turret and a turntable. The turntable is a rotating end and rotates during operation. The upper guide ring 1 is fixed on the turntable and rotates with the rotation of the turntable. The turret is a fixed end and is fixed. The lower guide ring 3 is fixed on the turret and remains stationary during operation. The rotation of the turntable drives the cable to move in the enclosure space formed by the upper guide ring 1 and the lower guide ring 3 to prevent the cable from slipping out of the guide ring and preventing the cable from winding around the water pipe.

[0072] The working machine provided by the present invention is described below. The working machine described below and the guiding device described above can be referred to in correspondence with each other.
