Description

Technical Field

[0001] This invention relates to the field of rotary base technology, and more particularly to a rotary base for a signal vehicle. Background Technology

[0002] Slewing bearings are a new type of mechanical component, consisting of inner and outer rings, rolling elements, etc. They are also known as slewing bearings or rotary bearings. Slewing bearings are large bearings capable of withstanding comprehensive loads, simultaneously bearing large axial and radial loads and overturning moments. Widely used in industry, slewing bearings are often referred to as the "joints of machines," serving as essential transmission components for machinery where relative rotational motion between two objects is required, and which must withstand axial forces, radial forces, and overturning moments. With the rapid development of the machinery industry, slewing bearings have found widespread application in shipbuilding equipment, construction machinery, light industrial machinery, metallurgical machinery, medical equipment, and industrial machinery.

[0003] Conventional vehicle-mounted rotary bases can achieve 360° rotation of the upper mechanism. However, in signal vehicle-mounted rotary bases, electromagnetic interference is easily generated during signal transmission. Strong electromagnetic interference can easily affect the signal transmission cable lines installed in the rotary base, thereby affecting the normal operation of the upper mechanism. Conventional vehicle-mounted rotary bases do not have effective means of electromagnetic shielding. Summary of the Invention

[0004] The purpose of this invention is to provide a signal vehicle slewing base for concealing the cables of the upper mechanism and shielding the electromagnetic interference to the upper mechanism's cable lines.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A signal vehicle slewing base for supporting an upper mechanism with cables, comprising:

[0007] Support section;

[0008] The rotating part is mounted on the support part and can rotate relative to it. The upper end face of the rotating part is connected to the upper mechanism.

[0009] The internal conduit, located inside the rotating section, is used to accommodate the cables of the upper mechanism and shield them from electromagnetic interference.

[0010] Compared with the prior art, the signal vehicle slewing base provided by the present invention has a bottom support part, and a slewing part is set on the support part and can rotate relative to the bottom support part. The upper mechanism is connected to the upper end face of the slewing part. The inner cable tube set inside the slewing part is used to accommodate the cable of the upper mechanism. Hiding the cable inside the inner cable tube can shield the electromagnetic interference generated by the signal vehicle from affecting the cable and avoid affecting the normal operation of the upper mechanism.

[0011] Preferably, in the above-mentioned signal vehicle slewing base, the support portion includes:

[0012] Base plate;

[0013] The support column is a hollow column. The lower end of the support column is fixedly connected to the base plate, and the upper end is used to support the rotating part.

[0014] This configuration, with the base plate and support columns fixedly connected, ensures the stable load-bearing function of the rotating base.

[0015] Preferably, in the aforementioned signal vehicle slewing base, the support portion further includes multiple support side plates, which are vertically arranged on the outer side of the support column, and the side of the support side plate near the base plate is fixedly connected to the base plate. This arrangement provides additional support when the slewing base bears a large load, improving the load-bearing capacity of the slewing base and ensuring its normal operation.

[0016] Preferably, in the aforementioned signal vehicle slewing base, the outer side of the support column is provided with opposing through holes for the drive source of the upper mechanism to pass through. This arrangement facilitates the passage of the drive source through the slewing base, ensuring a more compact and rational overall structure.

[0018] Slewing bearing, one end of which is bolted to the upper end face of the support column;

[0019] A slewing bearing seat is mounted on the slewing bearing. The center of the slewing bearing seat is hollow, and a groove is provided on the outer side of the slewing bearing seat to the hollow center. The groove is used to accommodate the inner conduit. With this configuration, the slewing bearing and the slewing bearing seat cooperate to allow the slewing base to rotate relative to each other, achieving the purpose of rotation. The inner conduit is placed in the groove to accommodate the inner conduit.

[0020] Preferably, in the aforementioned signal vehicle slewing base, baffles are arranged side by side in the groove, and the baffles have through holes through which the inner conduit passes. This arrangement restricts the position of the inner conduit in the slewing ring, ensuring that the position of the inner conduit does not affect the normal operation of the upper mechanism due to changes in position during the operation of the slewing base.

[0021] Preferably, in the aforementioned signal car rotary base, a conveying hole is provided on the upper end face of the rotary seat ring. With this configuration, the two ends of the cable of the upper mechanism can be fed into or out of the inner conduit through the conveying hole.

[0022] Preferably, the aforementioned signal vehicle slewing base also includes a motor, which is detachably mounted on the outside of the support.

[0039] Slewing bearings are a new type of mechanical component, consisting of inner and outer rings, rolling elements, etc. They are also known as slewing bearings or rotary bearings. Slewing bearings are large bearings capable of withstanding comprehensive loads, simultaneously bearing large axial and radial loads and overturning moments. Widely used in industry, slewing bearings are often referred to as the "joints of machines," serving as essential transmission components for machinery where relative rotational motion between two objects is required, and which must withstand axial forces, radial forces, and overturning moments. With the rapid development of the machinery industry, slewing bearings have found widespread application in shipbuilding equipment, construction machinery, light industrial machinery, metallurgical machinery, medical equipment, and industrial machinery.

[0040] Conventional vehicle-mounted rotary bases can achieve 360° rotation of the upper mechanism. However, in signal vehicle-mounted rotary bases, electromagnetic interference is easily generated during signal transmission. Strong electromagnetic interference can easily affect the signal transmission cable lines installed in the rotary base, thereby affecting the normal operation of the upper mechanism. Conventional vehicle-mounted rotary bases do not have effective means of electromagnetic shielding.

[0041] Example 1:

[0042] Please see Figures 1-2 The signal vehicle slewing base provided in this embodiment of the invention includes a support part 1, a slewing part 2, and an inner cable tube 3; wherein, the slewing part 2 is disposed on the support part 1 and can rotate relative to the support part 1, and the upper end face of the slewing part 2 is connected to the upper mechanism; the inner cable tube 3 is disposed inside the slewing part 2 and is used to accommodate the cable lines of the upper mechanism to shield the electromagnetic interference generated on the cable lines.

[0043] In this embodiment, the support part 1 includes a base plate 11 and a support column 12; wherein the support column 12 is a hollow column, the lower end face of the support column 12 is fixedly connected to the base plate 11, and the upper end face is used to support the rotating part 2.

[0044] In this embodiment, the support part 1 also includes a plurality of support side plates 13, which are vertically disposed on the outside of the support column 12, and the side of the support side plate 13 near the bottom plate 11 is fixedly connected to the bottom plate 11.

[0045] In this embodiment, the outer side of the support column 12 is provided with opposing through holes 121, which are used to drive the drive source of the upper mechanism.

[0046] In specific implementation: When the rotary base is in working condition, the support part 1 located at the bottom of the rotary base provides support for the entire rotary base. The upper end face of the base plate 11 of the support part 1 is fixedly connected to the lower end face of the support column 12. The rotary part 2 is located on the upper end face of the support column 12. When the rotary base bears a load, the support column 12 and the base plate 11 share the force, and the two cooperate to provide support for the entire rotary base, ensuring the stable load-bearing function of the rotary base. A support side plate 13 is vertically arranged on the outside of the support column 12. The side of the support side plate 13 near the base plate 11 is fixedly connected to the base plate 11. The upper part of the support side plate 13 is flush with the upper end face of the support column 12. When the rotary base bears a large load, the vertically arranged support side plate 13... Plate 13 can bear part of the force exerted by the upper mechanism on the support part 1, improving the load-bearing capacity of the entire rotating base and ensuring that the rotating base is in a stable working state under heavy load. The rotating part 2, which is set on the support part 1, can rotate relative to the support part 1. The upper mechanism is set on the upper end face of the rotating part 2 and is bolted to the rotating part 2. The rotation of the rotating part 2 drives the upper mechanism to rotate synchronously. The inner conduit 3 is set inside the rotating part 2, and the cable line of the upper mechanism is set inside the inner conduit 3. When the upper mechanism emits electrical signals, it generates strong electromagnetic interference to the entire system. The steel inner conduit 3 shields the electromagnetic interference from the upper mechanism's cable line, ensuring that the upper mechanism is in a normal working state under strong electromagnetic conditions.

[0047] As can be seen from the above specific implementation process, the support column 12 and the base plate 11 work together to provide load-bearing capacity for the upper mechanism, while the support side plate 13 set on the outside of the support column 12 greatly improves the load-bearing capacity of the entire support part, ensuring that the support part can be in normal working condition even under heavy load. The inner conduit 3 is set inside the rotating part 2. When the cable line of the upper mechanism is placed in the inner conduit 3, the steel inner conduit 3 can shield the electromagnetic interference to the cable line and avoid strong electromagnetic interference from affecting the normal operation of the cable line.

[0048] Example 2:

[0049] Please see Figures 1-4In this embodiment, the signal vehicle slewing base includes a support part 1, a slewing part 2, and an inner cable conduit 3. The slewing part 2 is disposed on the support part 1 and can rotate relative to the support part 1. The upper end face of the slewing part 2 is connected to the upper mechanism. The inner cable conduit 3 is disposed inside the slewing part 2 and is used to accommodate the cable lines of the upper mechanism to shield the electromagnetic interference to the cable lines. The support part 1 includes a base plate 11 and a support column 12. The support column 12 is a hollow column. The lower end face of the support column 12 is fixedly connected to the base plate 11, and the upper end face is used to support the slewing part 2. The support part 1 also includes a plurality of support side plates 13. The support side plates 13 are vertically disposed on the outside of the support column 12. The side of the support side plate 13 near the base plate 11 is fixedly connected to the base plate 11. The outside of the support column 12 is provided with opposing through holes 121, which are used to allow the drive source for driving the upper mechanism to pass through.

[0050] The rotating part 2 includes a slewing bearing 21 and a slewing ring 22; one end of the slewing bearing 21 is bolted to the upper end face of the support column 12; the slewing ring 22 is disposed on the slewing bearing 21, the middle of the slewing ring 22 is a hollow part, and a groove is provided from the outer side of the slewing ring 22 to the middle hollow part. The groove is used to accommodate the inner conduit 3. A baffle 221 is arranged side by side in the groove. The baffle 221 has a through hole 121. The inner conduit 3 passes through the through hole 121 of the baffle 221. A conveying hole 222 is provided on the upper end face of the slewing ring 22 for inputting and outputting the cable of the upper mechanism.

[0051] In specific implementation: the upper and lower end faces of the slewing bearing 21 are bolted to the upper end faces of the slewing seat ring 22 and the support column 12, respectively. When the direction of the upper mechanism needs to be adjusted, the slewing bearing 21 drives the slewing seat ring 22 to rotate, thereby driving the upper mechanism connected to the slewing seat ring 22 to rotate, achieving arbitrary adjustment. A groove is provided on the outer side to the middle hollow part of the slewing seat ring 22, and the inner conduit 3 is placed in the groove. When the upper mechanism is in contact with the slewing seat ring 22, the cable line of the upper mechanism enters the inner conduit 3. The groove can simultaneously accommodate and protect the inner conduit 3 and the cable line of the upper mechanism. The slewing seat ring 22 is equipped with parallel... Multiple baffles 221 are provided, each with a through hole 121 for the inner conduit 3 to pass through. In the working state, the through hole 121 restricts the position of the inner conduit 3, ensuring that the position of the inner conduit 3 does not change due to the rotation of the rotating seat ring 22, thus preventing the cable line inside the inner conduit 3 from affecting the normal operation of the upper mechanism due to rotation. Two conveying holes 222 are provided on the upper end face of the rotating seat ring 22. The two ends of the cable line of the upper mechanism are input and output through the conveying holes 222 respectively. In this way, when the rotating seat ring 22 rotates, it will not affect the two ends of the cable line of the upper mechanism, ensuring the synchronous rotation and normal operation of the cable line.

[0052] Example 3:

[0053] Please see Figures 1-6 Based on Embodiment 2, this embodiment further includes a motor 4 on the signal car slewing base. The motor 4 is detachably mounted on the outside of the support part 1. A drive gear 41 is mounted on the output shaft of the motor 4, and the drive gear 41 meshes with the gears of the two slewing parts.

[0054] In this embodiment, the inner conduit 3 is made of steel.

[0055] In specific implementation: a frame for accommodating the motor 4 is also provided on the outside of the support column 12. The motor 4 is detachably placed in the frame. In the working state, the motor 4 provides driving force for the rotation of the slewing bearing 21. When the motor 4 fails or needs to be replaced, the motor 4 can be taken out from the frame on the outside of the support column 12. A drive gear 41 is fixedly provided on the output shaft of the motor 4. The drive gear 41 meshes with the external gear of the slewing bearing 21. The slewing bearing 21 is driven to rotate by the drive gear 41.

[0056] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0057] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
