Description

Technical Field

[0001] The utility model relates to the technical field of loader accessories processing, in particular to a novel layout 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 electric towed excavator arrangement structure which is compact and can effectively save costs in view of the above problems.

[0006] To achieve the above-mentioned purpose, the utility model discloses a novel layout structure of a towed electric excavator, including 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 located between the left platform main beam and the right platform main beam is provided in the middle part of the main platform weld, a collector body is provided on the left platform main beam and the right platform main beam on the rear side of the rotary motor, a main valve is provided on the main platform weld below the collector, a drive motor is provided on the main platform weld on the rear side of the main valve, a whole machine radiator and an electric drive unit matching the drive motor are respectively provided on the left platform and the right platform weld on the left and right sides of the drive motor, an air conditioning drive unit is provided on the left platform weld in front of the whole machine radiator, and a hydraulic oil tank and a tool box mounting seat are provided on the right platform weld in front of the electric drive unit.

[0007] After adopting the above structure, by setting the collector body on the two platform main beams above the main valve 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, while the main pump position remains unchanged, and the original post-processing tank position is changed to an electric drive unit and coordinated with the hydraulic oil tank, the oil pipelines are all 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, ensuring that the high-voltage wiring harness is the shortest and there is a certain distance from the low-voltage wiring harness, avoiding signal and power transmission interference. The air-conditioning drive unit arranged on the left platform weld is more compact in layout structure, effectively increasing space utilization.

[0008] Preferably, the left platform main beam and the right platform main beam are respectively vertically arranged on the main platform weld along the length direction of the left and right sides of the main platform weld.

In this way, the external power supply is used as the power source, which does not rely on fuel, thereby avoiding exhaust emissions and noise and having minimal impact on the environment. At the same time, the cost of operation and maintenance is low and the service life is long, which can meet the 24-hour operation requirements.

[0010] Preferably, the main valve is welded on the main platform at the rear side of the rotary motor and the main valve and the rotary motor are located below the collector body. The main valve and the rotary motor are designed to be located below the collector body, making space utilization more reasonable and compact.

[0011] Preferably, the drive motor is arranged at the rear end of the main platform weld near the right platform main beam, and a water pump matching the whole machine radiator is arranged on the main platform weld on the left side of the drive motor and the water pump is arranged near the left platform main beam.

[0012] Preferably, the electric drive unit includes a main pump located on the right side of the drive motor and arranged on the right platform weld and matched with the hydraulic oil tank. A rectifier unit and a motor controller connected to the right platform weld are arranged above the main pump, and the motor controller is arranged on the upper end surface of the rectifier unit. In this way, the electrical components are concentrated on the right platform weld, which can facilitate the inspection and maintenance of the staff.

[0013] Preferably, the whole machine radiator is fixedly connected to the left platform weld in the vertical direction and fixedly connected to a position close to the left platform main beam along the length direction of the left platform main beam, and a plurality of battery groups are arranged on the left platform weld on the left side of the whole machine radiator along the length direction.

[0014] Preferably, the air-conditioning drive unit includes a rectangular protective frame close to the whole machine radiator and a shuttle valve group and a battery valve group welded on the left platform at the bottom of the rectangular protective frame. A protective sealing plate is arranged in the rectangular protective frame above the shuttle valve group and the battery valve group. An electric compressor and a water heater are arranged side by side on the protective sealing plate. An air-conditioning water tank is arranged on the side beam of the rectangular protective frame close to the left platform main beam, and an evaporator is arranged on the left platform welded on the front side of the rectangular protective frame. The rectangular protective frame can effectively protect the devices in the frame and can conveniently fix and install the air-conditioning water tank. The protective sealing plate is arranged to protect the shuttle valve group and the battery valve group. At the same time, it can also increase the space utilization rate of the space in the rectangular protective frame.

[0015] Preferably, the rear side wall of the hydraulic oil tank is arranged close to the front side wall of the rectifier unit and along the width direction of the right platform welding, and the tool box mounting seat is located at the front end portion of the right platform welding.

[0016] Preferably, the rectangular protective frame includes a left rectangular bracket and a right rectangular bracket which are respectively fixed to the left and right sides of the right platform along the vertical direction, and a reinforcing rib connecting the two rectangular brackets is arranged between the left rectangular bracket and the right rectangular bracket.

[0017] In summary, the beneficial effects of the utility model are: the utility model has a compact structure and is easy to repair and maintain.

By changing the original engine to a drive motor while the main pump position remains unchanged, and the original post-processing bin position is changed to an electric drive unit and matched with a hydraulic oil tank, the oil circuit pipelines are all in the shortest path and the electrical components are concentrated on the right platform weld.
