Problems solved by technology

The following problems exist in the use of this cable excavator: 1. The excavator needs to move on an irregular route within a certain range of work area, but the length of the cable is fixed at the maximum radius length of the activity area, so when the excavator is approaching When the tower crane is working, the cables are relatively loose, which is easy to cause accidents due to contact with the excavator; 2. The overall movement area of ​​the excavator is fan-shaped or circular. Multi-phase cables cannot be rotated repeatedly to maintain continuous power supply, which reduces operating efficiency; 3. Due to the high working intensity of excavators, complex and violent movements, and harsh working environment, cables are easily damaged, posing safety hazards

Embodiment Construction

[0015] combine Figure 1~3 , the cable-type electric excavator of the present invention includes an excavator 1, a cable 2 and a distribution box 3, and also includes the following two parts:

[0016] The first part is a weight-type rotary support located on the ground, including a first support rod 4 in a hollow structure and a cable cross bar 5, and a first slip ring 6 is installed on the upper end of the first support rod 4. The first slip ring includes a rotor 6a and a stator 6b. The rotor 6a is hollow, and N conductive rotor slides 6a1 are arranged along the rotor body. Conductive stator slider 6b1, the top of the rotor 6a is connected to the cable cross bar 5 through a hinged form, the bottom end of the stator 6b is fixedly connected to the first support bar 4, and one end of the cable cross bar is equipped with a balance weight 7,

[0017] The second part is a vehicle-mounted rotary support installed on the excavator, including a second support rod 8 in a hollow struct...

Abstract

The invention belongs to the field of engineering machines, and particularly relates to a power supply system of a cable type electric excavator. The system comprises a weight type rotating supportingstructure located on the ground and a vehicle-mounted type rotating supporting structure arranged on the excavator. Through joint effect of two collecting rings, when the excavator works, the excavator and excavator whole motion line 360-degree barrier-free rotation can be kept at the same time, and continuous power supply is achieved; through up and down swing of a cable transverse rod, the length of a cable line is controllable, touch with the excavator can be avoided, meanwhile, twisting and wear of the cable line can be greatly reduced, potential safety hazards are completely eradicated,and loss cost is reduced.

Description

technical field [0001] The invention belongs to the field of engineering machinery, in particular to a power supply system for a cable-type electric excavator. Background technique [0002] Excavator is one of the important equipment in construction machinery, which is used in various construction, water conservancy, electric power and mining operations. Traditional excavator products use fuel engine as the power source. The disadvantages are high fuel consumption, high operating cost, serious emission and noise pollution. Therefore, electro-hydraulic excavators are currently appearing to replace traditional equipment. Due to the current electric excavators with battery storage, the battery technology has not been widely used, and the cost is too high and the storage capacity is limited. It is not suitable for the high-power operation of the excavator. It is necessary to introduce a cable-type electric excavator for municipal cable distribution. In this case Generally, a to...
