Power assisting device for handcart switch of switch cabinet

Abstract

The invention discloses a power assisting device for a handcart switch of a switch cabinet. The power assisting device comprises an electric power input piece and a speed reduction transmission piece which are matched for use. The position of the switch cabinet handcart is controlled through cooperation of the electric power input piece and the speed reduction transmission piece, the electric power input piece is an independently-arranged component, and the speed reduction transmission piece is provided with an input shaft, a speed reduction gear set and an output shaft which are used in cooperation; and during use, the output shaft is clamped with an operation shaft of the switch cabinet handcart, then the output shaft is clamped with an input shaft of the speed reduction transmission part, the electric power input piece is started, power is transmitted to the input shaft through the output shaft, the speed reduction gear set reduces the speed of the power, and then the power is transmitted to the switch cabinet handcart through the output shaft, so that the switch cabinet handcart is controlled to be in a breaking position. According to the design layout of the device, input power is provided for the speed reduction transmission piece through manual operation, the input power can also be provided for the speed reduction transmission piece through the electric power input piece, the requirement for physical strength of operators is lowered, and meanwhile, the operation efficiency is effectively improved.

Description

technical field [0001] The disclosure generally relates to the technical field of electric power equipment, and in particular to a switch booster device for a switch cabinet handcart. Background technique [0002] The handcart is a trolley that is pushed by people. The withdrawing part of the switchgear is placed in the middle, and the main electrical components in the switchgear are installed on it, which is what people usually call a trolley. At present, the common types generally include PT handcart and switch (circuit breaker) handcart. The handcart is also called a trolley. Take the switch handcart as an example. When the switch is broken, it can be pulled out from the switch cabinet by hand after laying the guide rail for maintenance or replacement. [0003] However, the existing switch handcarts only support personnel to use the handcart handle to manually control the handcart switch, which seriously restricts the improvement of energy efficiency of the enterprise. ...

Problems solved by technology

[0003]However, the existing switch handcart only supports personnel to manually control the handcart switch by using the handle of the handcart, which seriously restricts the improvement of energy efficiency of the enterprise, and the switchgear supporting During the long-term use of the handcart handle, there will be problems of disrepair, damage and deformation, and the handcart handle is also easy to loosen and fall off during the shaking process, resulting in the failure of the handcart switch cabinet. Complete the operation tasks smoothly; at the same time, the operation of cranking in and out of the handcart has high requirements on the operator, requires certain strength and experience, and requires operational durability, and continuous operation poses a severe test to durability

Therefore, we propose a switch cabinet handcart switch assist device to solve the above problems of only supporting manual control, low energy efficiency, easy loosening and falling off of the crank handle, handcart can not smoothly complete the operation task, and the cranking of the handcart, Shake out the problem of demanding operators
