Embodiment 1

[0031] Embodiment 1: in combination with figure 1 , is a structural representation of the present invention. A power supply electric excavator device of the present invention is composed of a basic vehicle body unit, a vehicle-mounted utility pole unit, a vehicle-mounted motor unit, a static vehicle body moving unit and a power supply unit.

[0032] 1. The basic car body unit can be divided into the lower car body (1), the slewing platform (2), and the upper car body (3). They are all the original accessories of the original excavator, and their connection and operation methods remain unchanged. The upper car body part (3) is the remaining parts after the upper car body of the original excavator is removed from all its fuel power and corresponding accessories.

[0033] 2. The vehicle-mounted utility pole unit consists of a bearing base (4), a cylindrical lower support rod (5), a spring assembly (33), a small winch (7), an upper support rod (30), a pulley assembly, and a cable...

Embodiment 2

[0038] Embodiment 2: in combination with figure 2 , is a schematic diagram of the structure of the pulley assembly of the present invention. The pulley assembly includes a fixed pulley (15), a center fixed pulley (10), a tension fixed pulley (25), a fixed mount (11), a swing mount (14), a free mount (16), two Same tension spring (27), functional sensor (28), functional sensor (12) form. One end of the fixed mount (11) is connected to the fixed pulley (15) by a rod, and this end is vertically fixed on the upper end of the upper support rod (30), and its other end is connected to the central fixed pulley (10) and One end of swing type fixed mount (14). The other end of swing type fixed mount (14) connects tension fixed pulley (25) and an end of free type fixed mount (16) by bar shaft. The other end of freestyle fixed mount (16) is provided with the baffle plate with aperture. The contact pressure short plate (26) and the contact pressure plate (13) are arranged between the ...

Embodiment 3

[0039] Embodiment 3, in conjunction with attached image 3 , is a structural schematic diagram of the moving unit of the static vehicle body of the present invention. The moving unit of the static car body is made up of a worm gear reducer (37), a sensor (46), a clutch (43), and a manual lever (42) with a small-sized motor. Clutch (43) is fixed between the output shaft (44) of worm gear reducer (37) and the non-output end (41) of motor (38) power shaft, the output shaft (44) of worm gear reducer (37) and motor ( 38) the power shaft (41) is on a straight line (45). When the manual lever (42) is put down, that is, it is parallel to the plane of the slewing platform (2), the manual lever (42) touches the sensor (46), and the motor (38) that provides power for the car body has electricity and can start And clutch (43) is in leaving state and can't work; When manual lever (42) is brought up straight when it is perpendicular to the plane of rotary platform (2), manual lever (42) l...

Abstract

The invention discloses a power supply type electric excavator device, and relates to an engineering machine. The electric excavator device consists of a basic body unit, a vehicle-mounted power pole unit, a vehicle-mounted motor unit, a static body moving unit and a power supply unit. The basic body unit is an excavator body without a fuel engine system. The vehicle-mounted power pole unit consists of a bearing base, a spring assembly, a small winch, a pulley assembly, an upper supporting rod and a cylindrical lower supporting rod. The vehicle-mounted motor unit comprises a motor, a special distribution box and a cable. The static body moving unit comprises a small motor worm reducer, a clutch, a sensor and a manual rod. The power supply unit comprises a cement power pole, a common distribution box, a municipal power supply, a steel wire pull line, a cable hoisting ring and a power supply cable. According to the device, the structure and the using mode of the conventional excavator are not changed, the motor is used for replacing the fuel engine to provide power support for the body, barrier-free continuous power supply is realized through the vehicle-mounted power pole unit and the power supply unit, and electricity is used for replacing oil to realize zero emission.

Description

(1) Technical field [0001] The invention relates to engineering machinery, in particular to a power supply type electric excavator device. (2) Background technology [0002] Excavators are important equipment in the construction process. The current excavator products are powered by fuel engines, which can only consume fuel products and will inevitably produce various pollutions. [0003] If the power source of the existing excavator is changed, on the basis of not changing the basic structure, use form and operation mode of the existing excavator body, the electric motor is used instead of the fuel engine, and the power supply is continuously supplied in a barrier-free way, relying on its output The power output by the fuel engine replaces the power output by the fuel engine, which not only achieves zero emissions, but also greatly reduces the cost of use, which is a very meaningful thing. [0004] The technology and the method of existing excavator have following shortcom...
