Description

Auxiliary suspension device and method for transformer installation Technical Field The invention relates to the technical field of transformer installation, in particular to an auxiliary suspension device and method for transformer installation. Background The transformer is core equipment in the power transmission and distribution system, and the convenience and safety of installation operation of the transformer are directly related to the efficiency of power grid construction. In vast rural and urban junction areas, in order to save occupied space, a transformer is usually installed on a pole, namely, fixed on a cross arm or a special bench between two telegraph poles, and has a certain height from the ground. At present, for the installation of the pole-mounted transformer, two modes are generally adopted, namely, for an area with good road conditions, the transformer is mainly lifted to an installation height by a large hoisting machine such as a crane, and then is manually positioned and fixed. However, this method has a high requirement on the construction environment, and when facing mountain areas, hills or places where roads are narrow and rugged, cranes are often difficult to enter, resulting in incapacity of construction. Secondly, for places with limited terrains or inaccessible cranes, the traditional method is to build a scaffold, and hoist the scaffold by means of manual and simple hoisting tools (such as a chain block), or even adopt a manual lifting and transporting mode of multi-person cooperation. The method is time-consuming, labor-consuming and low in construction efficiency, has great potential safety hazards, and is easy to cause equipment damage or casualties. In order to solve the above problems, some improved auxiliary devices for hoisting transformers have been developed in the prior art. For example, some solutions propose to replace a crane for lifting by adopting a winding motor and a rope matched with a pulley. However, such devices still have significant limitations in practical applications. The device usually needs to fixedly install core components such as a winding motor, a bracket and the like at a specific height position of a telegraph pole in advance, and then carries out hoisting operation of the transformer. The installation mode is complex, and the installation and debugging of the equipment are also carried out at high altitude, so that the safety risk and the operation inconvenience are high. In addition, some solutions have proposed small hanging devices that can be fixed to a pole, but their structure is often complex and also faces the problem of how to conveniently transport and install the device itself at high altitude. Disclosure of Invention The invention provides an auxiliary hanging device and method for transformer installation, which can solve the following problems in the prior art: Because the mounting position of the transformer has a certain height, the mounting limitation of the hoisting equipment in the prior art is larger. The auxiliary hanging device for transformer installation comprises a positioning module fixedly installed between two groups of electric poles, wherein the positioning module is used for positioning and supporting a transformer main body to be installed; Two groups of hanging rings are symmetrically and fixedly arranged on two sides of the transformer main body respectively; the positioning module is also fixedly provided with a suspension module which is used for suspending and lifting the transformer main body through a suspension ring. Preferably, the positioning module comprises positioning frames which are symmetrically arranged on two sides of the two groups of electric poles in parallel, and the positioning frames are of U-shaped structures; wherein, the both ends of locating rack are fixed connection with the supporting part fixed in on the pole respectively. Preferably, the distance between the two groups of positioning frames is larger than the thickness of the transformer main body; The bottom of the transformer main body is fixed on the positioning frame through at least two groups of bearing frames respectively. Preferably, the two sides of the support respectively comprise a first support and a second support which are arranged in parallel along the vertical direction, the first support and the second support are arranged on two sides of the electric pole and are close to each other, two groups of U-shaped frames which are used for being matched and connected with the first support and the second support are respectively fixedly arranged on the opposite sides of the electric pole, away from each other, of the two sides of the electric pole, and the positioning frames are fixed on the second support; wherein, the reinforcing brackets are also fixedly arranged at the two ends of the first bracket and the second bracket. Preferably, the positioning module is further provided with a mounting module, and the mount
