Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
A portable electric operating tool for a handcart of a high-voltage switch cabinet is shown in figures 1-2 and comprises a shell 1 with a symmetrical double-handle structure, wherein the shell 1 is of a Y-shaped structure, double handles at the upper end are used for holding and operating left and right hands of an operator, the lower end is a power output end of the operating tool, and the output end is used for providing high-speed and high-torque for a screw rod. The design of the double handles is in accordance with the man-machine engineering, and the left-hand operation and the right-hand operation can apply reverse balance couple to the operating tool to balance the torque of the output end. Compared with the single-hand operation of a crank handle and an electric torque wrench held by a single hand, the double-handle operation can save more labor for an operator and provide larger reverse torque. In order to prevent accidental electric shock, the housing 1 is made of insulating ABS engineering plastic, which has good engineering strength. For the convenience of operation, a toggle switch for controlling the forward and reverse rotation of the motor 3 is arranged on the handle of the shell 1.
An energy storage battery 2, a motor 3, a speed reducer and an output shaft 4 are mounted in the housing 1. Wherein, energy storage battery 2 is two sets ofly, and two sets of energy storage battery 2 are plug connection respectively in the double handle. The energy storage battery 2 is a pluggable rechargeable battery, the working voltage of the energy storage battery 2 is 12V, the two groups of energy storage batteries 2 are connected in parallel, and the two groups of energy storage batteries 2 can be simultaneously powered and can also be independently powered. Two sets of energy storage battery 2 are set up, firstly, the electric storage capacity has been increased, secondly when one set of energy storage battery 2 is being pulled out and charges, and another set of energy storage battery 2 still can be for this operation instrument power supply.
The working voltage of the motor 3 is also 12V, and the motor 3 is powered by the energy storage battery 2 to drive the output shaft 4 to rotate through the speed reducer so as to output power. The connector of the screw rod on the existing high-voltage switch cabinet handcart is an inner square hole, so that the output end of the output shaft 4 is of a structure of a square connector 5 corresponding to the inner square hole, and the square connector 5 is inserted into the inner square hole during connection.
Because the weight of high tension switchgear handcart is great, in order to satisfy the needs of high tension switchgear handcart quick travel, the reduction gear will have great reduction ratio. Meanwhile, in order to make the operating tool small in size, light in weight and convenient to carry, the reducer is required to have smaller volume and weight. In order to solve the contradiction, the invention carries out integrated design on the speed reducer.
As shown in fig. 3, the speed reducer is composed of three stages of speed reducing mechanisms connected in series, namely a fixed-axis gear speed reducing mechanism 6, a harmonic gear speed reducing mechanism 7 and a planetary gear speed reducing mechanism 8. Wherein, the input end of the fixed shaft gear speed reducing mechanism 6 is connected with the motor 3, and the output end of the planetary gear speed reducing mechanism 8 is connected with the output shaft 4. The harmonic gear reduction mechanism 7 and the planetary gear reduction mechanism 8 are designed integrally, wherein an internal gear 71 in the harmonic gear reduction mechanism 7 and an internal gear 81 of the planetary gear reduction mechanism 8 share a same machine case 9, a flexible gear 72 in the harmonic gear reduction mechanism 7 is coaxially connected with a sun gear 83 of the planetary gear reduction mechanism 8, a wave generator 73 in the harmonic gear reduction mechanism 7 is connected with an output end of the fixed shaft gear reduction mechanism 6, and a planet carrier 82 of the planetary gear reduction mechanism 8 is connected with the output shaft 4. Thus, the torque output by the motor 3 is subjected to primary speed reduction by the fixed shaft gear speed reducing mechanism 6, secondary speed reduction by the harmonic gear speed reducing mechanism 7, and final three-stage speed reduction by the planetary gear speed reducing mechanism 8 and then output. After the three-stage speed reduction, the output torque is increased, and the rotating speed is reduced. The design can reduce the occupation of the reducer to the volume to the maximum extent, so that the operation tool is small in volume, light in weight and convenient to carry.
When the high-voltage switch cabinet handcart is operated, the high-voltage switch cabinet handcart can be quickly moved by only inserting the square connector 5 into the inner square hole of the screw rod and opening the toggle switch, so that the quick insertion and separation of the movable and fixed contacts are realized, and the movable and fixed contacts are prevented from being damaged due to long-time discharge. Compared with the manual hand-cranking mode in the background technology, the invention has the advantages of labor saving and high efficiency.
The details of which are not described in the prior art. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
