Abstract
The utility model relates to a three-phase oil-immersed distribution transformer mounting bolt spare. At present, in the installation process of the three-phase oil-immersed distribution transformer, the transformer needs to be lifted by a crane, when the lifted transformer reaches the installation position area, the installation of the bolt assembly can be carried out, and the whole process is time-consuming and labor-consuming. A three-phase oil-immersed distribution transformer mounting bolt piece, the constitution of which comprises: three-phase oil-immersed distribution transformer body (1) and bolt (2), the parallel welding in below of three-phase oil-immersed distribution transformer has two channel-section steels (3), set up the jack (5) that the diameter is the same on channel-section steel and mounting bracket (4) respectively, it has bolt assembly to insert in the jack, through bolt assembly with channel-section steel and mounting bracket fixed connection, the tip welding of bolt has U type rings (6), the threaded rod of bolt and the position department of nut have magnet piece (7) through the mode welding of spot welding. The utility model discloses be applied to the power supply field.
Description
The technical field is as follows:
the utility model relates to a three-phase oil-immersed distribution transformer mounting bolt spare.
Background art:
at present, in electric power system, during the job site installation transformer, need to align the installation round hole of welding on two channel-section steels of three-phase oil-immersed distribution transformer bottom with the round hole on two mounting brackets, then install transformer and mounting bracket through bolt assembly and fix, in the installation, need the crane to hoist the transformer, when the transformer that lifts by crane reachs the mounted position region, the slow promotion transformer of staff of top, detain two parallel C type channel-section steels in transformer bottom between two mounting brackets, make the round hole of installation on the C type channel-section steel counterpoint with the round hole on the mounting bracket, just can carry out bolt assembly's installation, whole process is consuming time hard, the installation effectiveness is low.
The invention content is as follows:
the utility model aims at providing a three-phase oil-immersed distribution transformer installation bolt spare.
The above purpose is realized by the following technical scheme:
a three-phase oil-immersed distribution transformer mounting bolt piece, the constitution of which comprises: three-phase oil-immersed distribution transformer body, the parallel welding in below of three-phase oil-immersed distribution transformer have two channel-section steels, channel-section steel and mounting bracket on seted up the jack that the diameter is the same respectively, the jack in insert bolt assembly, will through bolt assembly the channel-section steel with mounting bracket fixed connection, the tip welding of bolt have U type rings, the threaded rod of bolt and the position department of nut have the magnet piece through the mode welding of spot welding, the surface optional position department of magnet piece welding at the nut.
The three-phase oil-immersed distribution transformer mounting bolt piece, U type rings on detain and have had the spring hook, the round hole in-connection of spring hook have the metal stay cord, the metal stay cord pass the jack on channel-section steel and the mounting bracket respectively.
The utility model has the advantages that:
1. the utility model has simple structure and convenient operation, when installing the three-phase oil-immersed distribution transformer body, firstly the worker passes the bolt with the U-shaped hanging ring welded in advance through the jack on the installation frame, at the moment, the magnet welded on the surface of the bolt cap can be adsorbed with the installation frame, then the worker opens the hook opening of the spring hook to lock the spring hook in the U-shaped hanging ring on the bolt, then the metal pull rope on the spring hook is pulled to pass through the jack of the channel steel, then the pull rope is straightened, the channel steel can be driven to move along the direction of the metal pull rope when the pull rope is straightened, the channel steel drives the three-phase oil-immersed distribution transformer body to move when moving, thereby the jack on the channel steel is inserted into the face of the bolt, then the hook opening of the spring hook is opened, the spring hook is taken down from the U-shaped hanging ring on the bolt, and then the nut is screwed on, and finishing the installation work of the three-phase oil-immersed distribution transformer body.
The utility model discloses be convenient for process, only need be in advance at U type rings of the tip welding of bolt, any department in the plane of the nut of bolt through spot welding with magnet welding to nut department can, set up the magnet piece in order to make the bolt adsorb on the mounting bracket, do not need the staff to hold the bolt when the installation all the time, set up U type rings on the bolt, in order to make things convenient for practical spring hook, spring hook repeatedly usable, can be quick through the above-mentioned structure accomplish the installation work of three-phase oil-immersed distribution transformer body, the work efficiency is greatly improved.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a partially enlarged view of fig. 1.
Fig. 3 is a schematic view of the connection of the bolt to the metal cord.
In the figure: 1. three-phase oil-immersed distribution transformer body, 2, bolt, 3, channel-section steel, 4, mounting bracket, 5, jack, 6, U type rings, 7, magnet piece, 8, spring hook, 9, metal stay cord.
The specific implementation mode is as follows:
example 1:
a three-phase oil-immersed distribution transformer mounting bolt piece, the constitution of which comprises: three-phase oil-immersed distribution transformer body 1 and bolt 2, the parallel welding in below of three-phase oil-immersed distribution transformer have two channel-section steels 3, channel-section steel and mounting bracket 4 on seted up the jack 5 that the diameter is the same respectively, the jack in insert and to have bolt assembly, will through bolt assembly the channel-section steel with mounting bracket fixed connection, the tip welding of bolt have U type rings 6, the threaded rod of bolt and the position department of nut have magnet piece 7 through the mode welding of spot welding, the surperficial optional position department of magnet piece welding at the nut.
Example 2:
according to the three-phase oil-immersed distribution transformer mounting bolt piece in embodiment 1, the U-shaped hanging ring is buckled with the spring hook 8, the round hole of the spring hook is connected with the metal pull rope 9, and the metal pull rope respectively penetrates through the channel steel and the jack on the mounting rack.
Claims (2)
