Problems solved by technology

This method not only consumes a lot of manpower and is inefficient, but also is not conducive to the protection of finished buildings. The cleanliness of the environment during the construction process is difficult to meet the requirements of the network province company for the dust-free construction of GIS equipment.
[0004] At present, air cushion handling devices are gradually being used for GIS equipment handling. This method can effectively reduce labor costs and time costs during installation, and reduce damage to the ground during installation. At the same time, the personal safety of installation and operation and maintenance personnel is also high. can be effectively guaranteed
However, using this method also brings many new problems. One is that the existing air cushion handling device will blow a large amount of high-pressure gas to the ground during the handling process, and the high-pressure gas will raise the dust on the ground. This is different from the dust-free installation of GIS equipment. Second, the existing air cushion handling device has high requirements on the flatness of the construction ground. Once there are cracks and steps on the ground, the static pressure air suspension state of the air cushion handling device will be destroyed, and at least it will cause slippage, resulting in The GIS equipment cannot continue to be transported, and it will cause the GIS equipment to overturn and cause a major safety accident; the third is that the existing air cushion handling device has high requirements for the inclination of the construction ground, and the handling capacity of the air cushion handling device is 1 / 10,000 of the weight of the carrying equipment. Five, this means that only 5kg of force can be used to move a 10t heavy object. When the ground slope exceeds a certain limit (the limit varies according to the weight of the cargo), the air cushion device and GIS equipment may be due to gravity. As for accelerated sliding, because the GIS equipment has a large self-weight, the inertial force is large, and the existing air cushion device cannot brake suddenly, so once the sliding occurs, the consequences will be unimaginable
Fourth, the existing air cushion handling device has strict requirements on the air supply system. When the air flow is too large, it will cause the device to vibrate or jump up and down. When several air cushions are used together, it is more likely to be unstable, so it will also cause cause safety accidents
However, this type of truck cannot be fully adapted to GIS semi-indoor installation, because the GIS equipment is narrow, high, and long (for example, the size of a certain type of GIS equipment is 3.4 meters high, 6 meters long, and 1.4 meters wide), and in actual installation In order to save space, in most cases, multiple GIS devices are placed side by side, so there is limited operating space between GIS devices and between devices and walls. And the above-mentioned various shortcomings, this type of air-cushion truck does not solve, so it can be said that the application scenarios of the air-cushion truck and the air-cushion truck described in the present invention are completely different

Embodiment 1

[0041] Such as figure 1 , 2, 3 and 4, an air cushion handling device with road surface adaptive function, including a mounting plate 2, a cavity box 11, a dustproof module, a shock absorption module and an air cushion module 1. The cavity box 11 is fixed on the mounting plate 2 . The chamber box 11 is provided with a dust-absorbing chamber and an air-filled chamber which are independent of each other. The air cushion module 1 includes an air intake assembly and four air cushion units arranged in a square. The air cushion unit is in the shape of a ring. The top of the chamber box 11 is provided with an air inlet 9; the air inlet 9 is connected to an external air source. Four pneumatic control components are arranged in the air chamber. Pneumatic control components include on-off valves and air pressure sensors. The input port of the on-off valve is connected with the air inlet 9 on the chamber box 11 . The air pressure sensor detects changes in air pressure at the output...

Embodiment 2

[0052] An air cushion conveying device with road surface self-adaptive function, the difference between this embodiment and embodiment 1 is that: the number of air cushion units is set to two; the distance between the two air cushion units is 6 mm to 15 mm. In actual use, there is a direction requirement for the installation of the air cushion handling device; the direction of the center line of the two air cushion units is parallel to the direction of transportation. The actual maximum load of a single air cushion unit is T; the design load of the entire air cushion handling device is T Z =T.

Embodiment 3

[0054] An air-cushion transporting device with road-adaptive function, the difference between this embodiment and Embodiment 1 is that the number of air-cushion units is set to three; the three air-cushion units are arranged in a regular triangle. The actual maximum load of a single air cushion unit is T; the design load of the entire air cushion handling device is T Z =T.

Abstract

The invention discloses a road surface self-adaptive air cushion carrying device and a GIS equipment carrying method. The air cushion carrying device comprises a mounting plate, a cavity box, a dustproof module, a damping module and an air cushion module. The cavity box is fixed on the mounting plate. A dust collection cavity is formed in the cavity box. The air cushion module comprises an air inlet assembly and a plurality of air cushion units. Each air cushion unit is independently controlled . The dustproof module comprises a horn cover, vent holes, a filter and a vacuum generator interface. The horn cover with a downward opening is mounted at the edge of the mounting plate. The vent holes communicated with the dust collection cavity are formed in the mounting plate. The dust collection cavity is connected with an external vacuum source. And the damping module comprises a damper, a spring, a damping universal wheel and a damping mounting frame. The horn cover is arranged on the air cushion carrying device and is matched with an air suction mode, so that the condition of dust raising caused by an air floatation device is avoided, the working environment of a plant is prevented from deteriorating, and meanwhile, the GIS equipment can be prevented from being damaged due to dust raising.

Description

technical field [0001] The invention relates to an air cushion transporting device, in particular to an air cushion transporting device with a road surface self-adaptive function and a GIS equipment transporting method for substation semi-indoor GIS installation and operation and maintenance. Background technique [0002] With the continuous development of the smart grid, newly-built substations adopt GIS semi-indoor layout with small footprint and cost-effectiveness. In the factory building, the design of the inner drive with high input cost, low efficiency and high maintenance cost has been cancelled. However, the handling, installation and future operation and maintenance of GIS equipment weighing about ten tons is a very challenging task. [0003] GIS (Gas Insulated Substation) is the abbreviation of the English name of gas insulated substation. In a gas-insulated substation, most of the electrical equipment is directly or indirectly sealed in a pipe tree consisting of...
