Description
Technical Field
[0001] The utility model relates to the technical field of loader accessories processing, in particular to a new type of rotary platform arrangement structure of a towed electric excavator. Background Art
[0002] As an important equipment in construction projects, the power source of excavators has always been the focus of engineers. At present, excavators on the market are mainly divided into two categories: fuel-driven excavators and electric excavators. The power of fuel-driven excavators comes from the engine and fuel tank, while electric excavators rely on battery packs for power. However, at present, both fuel-driven excavators and electric excavators have certain problems and shortcomings.
[0003] First, the operating cost of fuel-driven excavators during construction is high. Due to the complex construction environment in which the excavator is located, there is a large demand for power, and fuel-driven excavators require a large amount of fuel to meet their power needs. In addition, fuel-driven excavators produce exhaust gas and noise during operation, which pollutes the environment and is not conducive to the order and safety of the construction site.
[0004] Secondly, although electric excavators can reduce exhaust and noise pollution, the demand for their battery packs has brought new problems. In order to meet the long-term operation requirements of the excavator, the battery pack is large in size and weight, and requires a longer platform and space to place it. This not only wastes a lot of manpower and material resources, but also puts higher requirements on the spatial layout of the construction site. Therefore, in order to save energy and cost, it is particularly important to improve the design and performance of electric excavators. Utility Model Content
[0005] The purpose of the utility model is to provide a new type of rotary platform arrangement structure of a towed electric excavator with compact structure and reasonable space utilization in view of the above problems.
[0006] To achieve the above-mentioned purpose, the utility model discloses a novel rotary platform layout structure of a towed electric excavator, comprising a main platform weld and a left platform weld and a right platform weld arranged on the left and right sides of the main platform weld, wherein a left platform main beam and a right platform main beam are respectively arranged on the left and right sides of the main platform weld, and its structural feature is that a rotary motor mounting opening located between the left platform main beam and the right platform main beam is provided in the middle of the main platform weld, and a collector mounting weld is respectively provided at the upper ends of the left platform main beam and the right platform main beam at the rotary motor mounting opening, and a collector body arranged in a vertical direction is provided on the two collector mounting welds, and a motor mounting bracket located on the left and right sides of the right platform main beam is provided at the rear of the main platform weld and the right platform weld, and a hydraulic oil tank mounting plate and a tool box mounting seat are provided on the right platform weld in front of the motor mounting bracket, a radiator mounting plate and a battery mounting plate are provided at the rear of the left platform weld, and an electromagnetic valve group mounting plate is provided near the middle position of the left platform weld.
[0007] After adopting the above structure, by installing the collector body on the platform main beam and using electric energy as the power source, the placement of the battery pack is reduced, the length of the platform weld is reduced, and the production cost is reduced. By changing the original engine to a drive motor and cooperating with the hydraulic oil tank mounting plate and the tool box mounting seat welded on the right platform, the oil pipeline can be routed in the shortest path and the electrical components are concentrated on the right platform weld. In this way, the high-voltage wiring harness is also concentrated here to ensure that the high-voltage wiring harness is the shortest and there is a certain distance from the low-voltage wiring harness. The radiator mounting plate, battery mounting plate and solenoid valve group mounting plate arranged on the left platform weld facilitate the later installation of the air-conditioning drive unit, which makes the overall layout structure more compact and effectively increases the space utilization.

By installing the collector installation welding at the corner of the upper end face of the two platform main beams and making the two horizontal plates located on the same horizontal plane, it is convenient to provide a flat installation surface for the collector body and effectively ensure the stability of the collector body.
[0011] Preferably, the collector body includes a collector mounting bracket mounted on two horizontal plates, the collector mounting bracket is provided with a collector frame and a high-voltage electrical interface, and the collector mounting bracket includes two rectangular support frames respectively fixed to the upper end faces of the horizontal plates, and a plurality of reinforcing beams connecting the two rectangular support frames are provided on the upper part between the two rectangular support frames. In this way, an external power source is used as a power source, which does not rely on fuel, thereby avoiding exhaust emissions and noise generation and having minimal impact on the environment.
[0012] Preferably, the motor mounting bracket includes two supports located in the right platform weld and fixed on the right platform main beam at intervals along the length direction of the right platform main beam, and also includes two supports arranged at the rear of the main platform weld and respectively fixed to the rear end face of the middle plate and the front end face of the rear plate. The motor mounting bracket is close to the right platform weld, so that the oil pipeline and the high-voltage wire harness can be directed in the shortest path and the electrical components are concentrated on the right platform weld.
[0013] Preferably, the tool box mounting seat is respectively arranged on the front end body welded to the right platform and on the body welded to the right platform near the front side of the hydraulic oil tank mounting plate.

[0016] In summary, the beneficial effects of the utility model are: the utility model has a compact structure and reasonable space utilization, and by installing the collector body on the platform main beam and using electric energy as the power source, the placement of the battery pack is reduced, the length of the platform weld is reduced, and the production cost is reduced. By changing the original engine to a drive motor and cooperating with the hydraulic oil tank mounting plate and the tool box mounting seat welded on the right platform, the oil pipeline can be directed to the shortest path and the electrical components are concentrated on the right platform weld, so that the high-voltage wiring harness is also concentrated here, ensuring that the high-voltage wiring harness is the shortest and there is a certain distance from the low-voltage wiring harness.
