Problems solved by technology

[0002] When replacing equipment (such as isolating switches, transformers, lightning rods, etc.) in substation technical renovation, since these equipment are installed on the frame, it cannot be completed by manpower alone. Generally, it is necessary to use a crane or a pole for hoisting. If a crane is used for replacement, The power outage range is large and the cost is high. Some substation equipment is limited by the construction environment. In specific construction, the power outage range is often only an interval, surrounded by live equipment, so cranes cannot be used; due to its relatively long length and heavy volume, the pole , transportation and handling are inconvenient, and the space inside the substation is small, surrounded by live equipment, the poles often cannot meet the safety distance from the live equipment when in use, the use of the poles is limited to a certain extent, and the poles may touch adjacent Discharge of live equipment poses a safety hazard
When fixing the pole, the pole is usually tied against the frame with ropes. Once the rope is loose during the construction process, the pole may overturn, resulting in poor stability and reliability.

Embodiment Construction

[0014] like figure 1 , figure 2 As shown, the substation power equipment lifting device provided by the present invention includes a vertical seat tube 9, combined with image 3 As shown, two hoops 10 are welded at intervals on the circumferential surface of the lower section of the seat tube 9. In order to increase the strength, a reinforcing plate 12 is welded and fixed with the seat tube 9 on both sides of the hoop welded and fixed with the seat tube. Fixed connection with the pole of the installation frame through bolts 11, combining Figure 4 As shown, the upper port of the seat tube 9 is inserted into a right-angle elbow 5 that fits in the clearance of the inner wall of the seat tube 9, and the vertical section 6 of the right-angle elbow 5 is provided with a ring limiter that is equal to the outer diameter of the seat tube 7. A plane bearing 8 that matches the upper end surface of the seat tube 9 is arranged below the circular ring limit platform 7 on the vertical sec...

Abstract

The invention discloses a hoisting device for electric equipment of a transformer substation. The hoisting device comprises a base tube, wherein a hoop is fixedly connected with the circumference face of the base tube; a right-angle elbow pipe in gap fit with the inner wall of the base tube is inserted in an upper port of the base tube; a hoisting ring used for connecting a pulley is arranged on the horizontal section of the right-angle elbow pipe; and a circular limiting table which is equal to the external diameter of the base tube is arranged on a vertical section of the right-angle elbow pipe. The hoisting device uses a double-section assembling manner, so that the length of a single rod is reduced; the hoisting device is convenient to carry, transport and mount, satisfies the safe distance with the electric equipment, and is particularly applicable to the transformer substation with a narrow space; the traditional rope fixing manner is changed, and the hoisting device is fixed by using the loop through bolts, so that the stability and the reliability of the device can be improved; through the internal practical test of an enterprise, the working time of mounting and replacing equipment such as an isolation switch, a lightning rod and a mutual inductor can be greatly reduced when being compared with the existing working time; and the safety is greatly improved.
