Abstract
The utility model discloses a high and low voltage collecting ring for a variable-frequency excavator, which comprises a body, a high voltage collecting ring, a low voltage collecting ring and a carbon brush component, wherein a lower end plate of the high voltage collecting ring is connected with an upper end plate of the low voltage collecting ring by using a fastener, the carbon brush component is arranged on a ring body end cover by using a bearing and consists of an end cover, an insulating shaft, a spring compaction device, another insulating shaft, an insulating bracket, an insulating fastener, a brush box and a carbon brush, the brush box is provided with the carbon brush, one end of the carbon brush is connected with the spring compaction device, the brush box is installed on the insulating bracket, and the insulating bracket is fixed on the insulating shaft by using the insulating fastener. The high and low voltage collecting ring adopts a compact integral structure, and still has good insulativity in the situation that the overall dimensions of the collecting ring are limited.
Description
Technical field
The utility model relates to a kind of current collecting equipment, particularly a kind of frequency conversion excavator high-low pressure collector ring.
Background technology
The frequency conversion excavator is important auxiliary products in the frequency conversion excavator with the high-low pressure collector ring.Because the high pressure that the frequency conversion excavator adopts is the 10KV level, very high to the insulating requirements of collector ring, existing collector ring all adopts external product, its complex structure, cost height.
Summary of the invention
In order to solve the above-mentioned technical problem that collector ring exists, the utility model provides a kind of simple in structure, technology is reasonable, cost of manufacture is low, insulation property are reliable, convenient for installation and maintenance frequency convertor excavator high-low pressure collector ring.
The technical scheme that the utility model solves the problems of the technologies described above is: comprise body, high pressure collector ring, low pressure collector ring, carbon brush component, the bottom plate of high pressure collector ring is connected with securing member with the upper head plate of low pressure collector ring, and carbon brush component places on the ring body end cap with bearing.
Above-mentioned frequency conversion excavator is with in the high-low pressure collector ring, described carbon brush component is made up of end cap, insulation axle, spring attachment, insulation axle, insulating support, insulation securing member, brush box and carbon brush, brush box is equipped with carbon brush, one end of carbon brush links to each other with spring attachment, brush box is installed on the insulating support, with the insulation securing member insulating support is fixed on the insulation axle.
Technique effect of the present utility model is: 1) aesthetic in appearance, the compact conformation of the utility model has good insulation performance.2) carbon brush component of the present utility model has adopted the spring hold down gag, makes the contact-making surface of carbon brush and conducting ring that enough pressure be arranged, and has reduced contact resistance, has guaranteed the functional reliability of collector ring.
Below in conjunction with accompanying drawing the utility model is further described.
