[0035] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention.

[0036] The utility model also has the following implementation methods based on the above:

[0037] In a further embodiment of the present invention, the safety protection structure 4 is one of a lifting belt or a connecting steel.

[0038] In a further embodiment of the utility model, there are two channel steel rails 6 , both of which are arranged along the first direction, and both ends of the steel structure beam 2 are respectively installed on the two channel steel rails 6 .

[0039] In a further embodiment of the present invention, the steel structure beam 2 and the I-beam rail 8 are arranged along the second direction, and the electric lifting device can move along the second direction on the I-beam rail 8.

[0040] Furthermore, the first direction is Figure 1 The left and right directions in the second direction are Figure 1 The up and down directions in .

[0041] In a preferred embodiment, since the installation processes of the turbine foundation components and the bearing box are both high-altitude edge operations, there are certain safety risks. During the installation of the turbine, a series of operations are required, such as hoisting the guide of the low-pressure cylinder, installing the foundation components and the anchor bolts of the bearing box, hoisting, installing and welding the anchor bolt pads, etc., and it is also necessary to measure relevant data such as the position, elevation and horizontality of the foundation components. It is necessary to repeatedly erect cantilever frames at high-altitude edge positions, which has a high safety risk. At the same time, the condenser below is in the peak construction period, and the erection of the cantilever frame will inevitably affect the construction of the condenser.

[0042] In a preferred embodiment, during the installation of the low-pressure cylinder of the steam turbine, the installation conditions at each stage are quite different. At the same time, the condenser under the steam turbine is under construction at this stage. Therefore, based on the installation method of the steam turbine foundation components, the characteristics of the foundation structure, the main line installation requirements, and the on-site high-altitude edge operations and other related conditions, an electric platform for installing the foundation components of large equipment is designed to meet the installation requirements of the low-pressure cylinder guide pins, piers, foundation embedded plates, bearing boxes, and anchor bolts, ensuring safety and control during the installation process to avoid affecting the installation of the condenser. If the anchor bolts of the steam turbine are installed inside the steam turbine beam, and the installation positions are scattered, it is necessary to install the pads and nuts from different installation holes on the side of the steam turbine beam. The installation hole elevation is 4.5m, and the ground elevation below is -18.87m, with a drop of more than 20m. The guide pin has an overall dimension of φ500×2585mm and weighs 4.033t. It needs to penetrate from one end of the steam turbine beam to the other end. The single-sided gap between the guide pin and the embedded sleeve is only 10mm. At the same time, the guide pin installation position is supported by the bearing box foundation boss, making it difficult to use the crane in the factory to directly lift it. In view of this situation, the device spans the left and right beams of the steam turbine.

It avoids repeated erection and dismantling of cantilever frames at high edge locations, provides a safe working platform for low-pressure cylinder related installation operations, and effectively improves the inherent safety of the construction process.

[0045] In a preferred embodiment, Figure 4 As shown, the steel structure girder 2 is mainly composed of H-shaped assemblies, and after assembly, it can be hoisted as a whole through the four lifting ears on the top of the steel structure girder 2. A railing 1 is arranged above the steel structure girder 2, and a steel springboard is laid, so that personnel can walk and work on the top of the steel structure girder 2. Two electric hoist 3 tracks are arranged below the steel structure girder 2 for installing the electric hoist 3. A cable sliding device is arranged on the inner side of the track for installing the lifting rope. Further, the lifting rope specifically adopts the electric hoist 3 cable, and corresponding limit devices are arranged at both ends of the track.

[0046] Furthermore, in addition, the hanging basket 5 can also be operated by remote wireless control; the hanging basket 5 has four steel columns welded on the bottom crossbeam, and two electric hoists 3 are connected to the lifting ears on the top of the steel columns of the hanging basket 5. The electric hoists 3 are controlled by a wireless remote controller, and the electric hoists 3 and the hanging basket 5 can be controlled to move left and right and up and down under the platform. Four ground bulls 7 are designed at the bottom of both ends of the steel structure beam 2, and two channel steel rails 6 are set on the turbine foundation beam. The steel structure beam 2 can move forward and backward as a whole during use. In this way, the device can be moved and dispatched in the front, back, left, right, up and down, and can cover the entire installation area of ​​the front and rear beam facade foundation components of the low-pressure cylinder of the steam turbine. The problem of difficult installation of the turbine foundation components is effectively solved.
