Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, specifically relating to a cable bracket mounting structure. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] The application of new energy technologies in the construction machinery field is accelerating and deepening, and electrification and decarbonization have become industry development trends. Among them, electric-powered excavators, as green construction equipment that relies on external cables for power supply, are increasingly widely used in municipal engineering, indoor operations, and other scenarios due to their advantages such as zero emissions, low noise, and high energy efficiency.

[0004] However, the stable operation of electric-powered new energy excavators highly depends on the safe laying and support of cables. The cable bracket mounting structure, as a key structural component connecting the cable support and the excavator chassis, directly affects the operational reliability and service life of the equipment. Existing cable bracket mounting structures are mostly welded directly to the X-frame of the excavator chassis on one side. This results in high unilateral support stress, high strength requirements, and high welding and material costs. Furthermore, the excavator's X-frame is a closed cavity structure with a large volume. If the welded mounting seat experiences loose welds or structural deformation, maintenance personnel cannot easily access the cavity for inspection and repair. This often necessitates partial disassembly of the X-frame, which is not only time-consuming and labor-intensive but may also cause secondary damage to the overall structural strength of the X-frame, significantly increasing equipment maintenance costs and downtime.

Detailed Implementation

[0020] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0021] The stable operation of electric-powered excavators highly depends on the safe installation and support of cables. The cable bracket mounting structure, as a key structural component connecting the cable support to the excavator chassis, directly impacts the equipment's operational reliability and service life. Existing cable bracket mounting structures are mostly welded directly to the excavator chassis's X-frame on one side. This results in high single-sided support stress, high strength requirements, and high welding and material costs. Furthermore, the excavator's X-frame is a closed cavity structure with a large volume. If the welded mounting bracket experiences loose welds or structural deformation, maintenance personnel cannot easily access the cavity for inspection and repair. This often necessitates partial disassembly of the X-frame, which is not only time-consuming and labor-intensive but may also cause secondary damage to the overall structural strength of the X-frame, significantly increasing equipment maintenance costs and downtime.

[0022] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a cable bracket mounting structure, such as... Figure 1 and Figure 2 As shown, it includes a drum support mounting plate 1, with an upper cover plate 2 at the upper end of the drum support mounting plate 1; upright plates 4 are symmetrically arranged at one end of the drum support mounting plate 1, with an upper splicing plate 3 at the upper end of the upright plates 4; reinforcing plates 6 are arranged in the middle of both ends of the drum support mounting plate 1, and a lower cover plate 7 is arranged at the lower end of the drum support mounting plate 1.

[0023] Specifically, the two ends of the reel bracket mounting plate 1 and the lower cover plate 7 of the cable bracket mounting base structure 12 are welded to the underframe track beam 13. The upright plate 4 is connected to the X-frame 11 by welding. The cable bracket is connected to the reel bracket mounting plate 1 and the upper cover plate 2 of the cable bracket mounting base structure 12 by bolts. This increases the number of support positions of the cable bracket mounting base structure 12, reduces the material usage, and saves costs. Furthermore, a reinforcing plate 6 is set in the middle of both ends of the reel bracket mounting plate 1, a reinforcing corner rib 5 is set at the end of the lower cover plate 7, and an inner reinforcing corner rib 9 is set at the connection position of the reel bracket mounting plate 1 and the lower cover plate 7, which ensures the overall strength and the strength of the connection position, and can provide stable support.

[0024] The upper end of the roller support mounting plate 1 is fixedly connected to the upper cover plate 2, and one end of the upper cover plate 2 is fixedly connected to one end of the upper splicing plate 3. The other end of the upper splicing plate 3 has a bent structure.

[0025] Specifically, the bending structure of the upper splicing plate 3 matches the shape of the upper end face of the vertical plate 4. The design of the bending structure facilitates the connection between the upper splicing plate 3 and the vertical plate 4, while increasing the welding area of ​​the cable bracket mounting base structure 12 and the X-frame 11, making the connection more robust.

[0026] One end of the drum bracket mounting plate 1 is fixedly connected to the vertical plate 4, and the lower end of the drum bracket mounting plate 1 is fixedly connected to the lower cover plate 7.

[0027] Specifically, the upright plate 4 of the cable bracket mounting base structure 12 creates a non-enclosed space between the cable bracket mounting base structure 12 and the X-frame 11. The non-enclosed space is relatively large, which facilitates the assembly and maintenance of cables, junction boxes and other accessories. A cable support base 10 is also provided to install cables, which makes cable laying even easier.

[0028] The lower cover plate 7 is provided with a reinforcing rib 5 at its end, and the reinforcing rib 5 is fixedly connected to the lower cover plate 7.

[0029] Specifically, by strengthening the corner ribs 5, the two ends of the cable bracket mounting structure 12 can be firmly connected to the underframe track beam 13, ensuring the strength of the connection, resisting the bending and deformation of the structure under stress, making the structure more stable, and also dispersing stress concentration to avoid excessive local stress leading to breakage.

[0030] A screw seat 8 is provided on the side of the upright plate 4. Several screw seats 8 are arranged at intervals and are mounted on the drum support mounting plate 1.

[0031] A circular hole 15 is provided in the middle of the drum support mounting plate 1, and several screw holes 16 are provided at intervals along the outer edge of the circular hole 15. A cable support 10 is provided at one end of the circular hole 15, and the lower end of the cable support 10 is fixedly connected to the upper end of the lower cover plate 7. Specifically, the cable support 10 is used to support and place the cable. The circular hole 15 in the middle of the drum support mounting plate 1 is for passing the cable through, and the screw holes 16 are for installing and fixing the cable device.

[0032] The upper end of the lower cover plate 7 is provided with an inner reinforcing rib 9, and several inner reinforcing ribs 9 are arranged at intervals. One end face of the inner reinforcing rib 9 is fixedly connected to the lower cover plate 7, and the other end face of the inner reinforcing rib 9 is fixedly connected to the drum bracket mounting plate 1.

[0033] Specifically, the connection strength between the roller bracket mounting plate 1 and the lower cover plate 7 is increased by the internal reinforcing ribs 9, thereby preventing breakage. Compared with simply thickening the structural body, the amount of material used can be reduced while ensuring strength, thus achieving lightweighting.

[0034] Several through holes are provided at intervals on the drum bracket mounting plate 1 and the upper cover plate 2. The through holes are used for bolts.

[0035] like Figure 3 , Figure 4 as well as Figure 5 As shown, the installation method of the cable bracket mounting base structure 12 is as follows: During installation, the two ends of the drum bracket mounting plate 1 and the lower cover plate 7 of the cable bracket mounting base structure 12 are welded to the bottom frame track beam 13. The upright plate 4 is connected to the X-frame 11 by welding. The cable bracket 14 is connected to the drum bracket mounting plate 1 and the upper cover plate 2 of the cable bracket mounting base structure 12 by bolts. Welding at multiple positions is achieved, thereby ensuring the connection strength and improving the stable support.

[0036] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
