Problems solved by technology

In the process of realizing the present invention, the inventor found that the prior art has at least the following deficiencies: it is inconvenient for the staff to carry their own tools during the operation, and the work efficiency is low, and there are many hidden safety hazards in the work; in addition , the cost of building cement steps in front of the pole-type transformer bench is relatively high, and it is easy to cause other problems
[0003] In addition, considering the convenience of transformer maintenance, the staff would like to build a platform on site, but considering the complex surrounding conditions and the high risk of transformers, it is difficult to reserve a permanent maintenance platform on the transformer, so scaffolding needs to be erected on site for each maintenance construction
However, due to the transformer structure and other reasons, there are the following problems in scaffolding construction: 1. Below the construction point of disconnection and re-leading is the transformer radiator and its pipelines, control systems, etc., and it is difficult to apply ordinary quick-installation scaffolding; 2. Multiple main transformers may be distributed in batches Different, or because of the transformation, there are different dimensions and heat dissipation system structures, so it is impossible to make a set of universal quick scaffolding. If it is made separately according to each transformer, the cost of equipment procurement will be doubled; 3. Using steel pipe / bamboo springboard Although scaffolding is low in cost and flexible in structure, it has defects such as limited bearing capacity, long construction period, and easy damage to the transformer heat dissipation system or bushing.
This invention still does not have the ability to lift heavy objects, and it has relatively large limitations during maintenance

Embodiment 1

[0033] like Figure 1 to Figure 5As shown: this embodiment provides a small transformer auxiliary platform for urban distribution network, including a car body 1, a sliding track 7 set on the car body 1, and a first translation mechanism 2 parallel to each other is set on the sliding track 7 and the second translation mechanism 29, the first translation mechanism 2 and the second translation mechanism 29 are provided with a lifting mechanism, the top of the lifting mechanism is provided with an inspection platform 3, and the front end of the inspection platform 3 is movable to set an L-shaped hanger 9, The rear end of the vehicle body 1 is provided with an L-shaped bracket 8 .

[0034] The inspection platform is rotated and set on the top of the lifting mechanism, and the inspection platform is telescopically set, so that when inspecting any part of any side of the transformer, by rotating the direction of the inspection platform and adjusting the translation mechanism, the L-...

Embodiment 2

[0038] like Image 6 Shown: its difference with embodiment one is:

[0039] The L-shaped hanger 9 is movably arranged on the front end of the second bottom plate 17, and the front end of the second cross arm 18 is movably provided with a docking mechanism; Pipes 23, a third bottom plate 22 is arranged between the fixed pipes 23; a rotating base 26 is arranged at the front end of the second bottom plate 17, and a fixed socket 27 is arranged on the rotating base 26 corresponding to the L-shaped hanger 9 .

[0040] The maintenance platform is set on the two sides corresponding to the transformer through the first translation mechanism and the second translation mechanism, and the docking mechanism is movable at the front end of the second cross arm, so that the height of the maintenance platform is higher than that of the transformer, and the front ends of the two maintenance platforms can be rotated after rotation. Butt together, so as to build a hanging and maintenance platfo...

Embodiment 3

[0042] like figure 1 Shown: its difference with embodiment one is:

[0043] The lifting mechanism includes a hydraulic lifting column 4 and a supporting base 13 that is rotatably connected to the lower end of the hydraulic lifting column 4. A drive motor 15 is arranged on the supporting base 13, and an annular rack 14 is arranged at the bottom of the hydraulic lifting column 4. The driving motor 15 is connected to the ring rack 14 through a reduction box 16 in transmission.

[0044] The translation mechanism includes a lead screw 11, a translation motor 28 for driving the lead screw 11 and a fixed rod 10 matched with the lead screw 11, and a slider 12 is sleeved on the lead screw 11 and the fixed rod 10, so that The support base 13 is provided on the slider 12; the outer surface of the screw 11 and the fixed rod 10 is provided with a graphite lubricating layer.

[0045] The lifting mechanism adopts a hydraulic lifting column, which has stronger lifting strength and better st...

Abstract

The invention discloses an auxiliary platform for a small-size transformer of an urban distribution network, and the platform comprises a vehicle body and a sliding rail disposed on the vehicle body. The sliding rail is provided with a first translation mechanism and a second translation mechanism, which are parallel to each other. The first and second translation mechanisms are provided with a lifting mechanism, and the top of the lifting mechanism is provided with an inspection and maintenance platform. The front end of the inspection and maintenance platform is movably provided with an L-shaped suspension bracket, and the rear end of the vehicle body is provided with an L-shaped support. When the platform is used for the inspection and maintenance of a pole-type transformer, the platform can achieve the hoisting movement of specific equipment or parts, does not need to carry out the auxiliary operation of other hoisting equipment, prevents the additional hoisting equipment from participating, enables a worker to conveniently inspect and repair the transformer, and also improves the safety during inspection and maintenance. The inspection and maintenance platforms cooperate with each other for butt joint, so the platform can achieve the hoisting and installation of a transformer under the condition that a wire above the transformer is not disassembled, and is more flexible and convenient to use.

Description

technical field [0001] The invention relates to the technical field of transformer auxiliary equipment, in particular to a small transformer auxiliary platform for urban distribution network. Background technique [0002] With the improvement of people's living standards, the demand for electricity continues to increase, and they hope to have qualified voltage quality and uninterrupted power services. Therefore, it is the responsibility of each of our electric power employees to improve the reliability of power supply, strengthen the maintenance of power equipment, and shorten the repair time. The transformer on the pole is the most important power supply equipment, and the staff are operating at high altitude when operating, maintaining and repairing the transformer on the pole. In recent years, with the continuous advancement of urban power grid upgrading and transformation, due to the limitations of funds and distribution transformer installation locations, most platforms...
