Problems solved by technology

[0002] In daily maintenance work, we will come into contact with a large number of high-altitude operations on suspended slopes. If it is necessary to perform maintenance operations on such parts, it will be a great test for the maintenance personnel. Currently, such parts The main method used for high-altitude operations is: first, according to the angle of the suspended slope on site, use channel steel welding to make a support tripod, then drill holes on the suspended slope and plant bars, and then connect the support tripod with the planted bars by welding, and then All the tripods are welded into an integral frame on the horizontal plane through channel steel, and a springboard is laid on it to build a maintenance platform for maintenance personnel. The platform requires a lot of manpower during the erection process, and the time required for erection is also very long. It is a very dangerous job for construction workers because it is long and suspended in the air
At the same time, the platform is not flexible enough in the process of installation and dismantling. Different tripods need to be customized according to different slopes on site. It cannot take into account the maintenance requirements of slopes with different angles, and cannot have universal performance. Drilling holes and planting bars on the suspended slope will cause great damage to the foundation slope body, easily destroy the foundation concrete of the slope, and make the foundation surface loose, which poses a certain safety hazard. The principles of fast, efficient and safe maintenance are not in line with

Embodiment 1

[0042] Such as Figure 1-18 Among them, the quick-installation maintenance platform on the suspended slope at the outlet of the flood discharge channel of the hydropower station includes foundation embedded parts, support structures, platform structures and protective structures. In the inclined surface of the foundation, a plugging cover 2 is provided on the foundation thread seat 1, and a protective plate 3 is provided between the foundation thread seat 1 and the supporting structure;

[0043]The support structure includes a slanted column 4, a vertical column 5, a horizontal bar 6, a reinforcing beam 7 and a locking clip 8, and the two ends of the slanted column 4 are provided with a fixed hinge seat 4-1 and a plurality of threaded seats 1 to cooperate with the foundation. The bolt installation through hole 4-2, the bottom of the column 5 is provided with the first movable support hinge 5-1 that cooperates with the fixed hinge seat 4-1 by the bolt, and the top of the column...

Embodiment 2

[0055] Such as Figure 1-18 Among them, the installation method of the quick-installation maintenance platform on the suspended slope at the outlet of the flood discharge channel of the hydropower station is as follows:

[0056] 1. Pre-embed multiple sets of basic threaded seats 1 in the concrete of the suspended slope by means of chemical value reinforcement;

[0057] 2. When building the maintenance platform, first install the protective plate 3 through the installation through hole 3-1 with multiple sets of basic threaded seats 1, and then install and connect the inclined column 4 with the basic threaded seat 1 by threaded connection;

[0058] 3. Connect the two ends of the inclined column 4 to the column 5 and the horizontal bar 6 through the fixed hinge seat 4-1, then adjust the height of the positioning nut 5-3 on the column 5 to keep the horizontal bar 6 in a horizontal position, and then pass the second A locking nut 5-4 is fixed;

[0059] 4. Place the reinforcing be...
