Description

Technical Field

[0001] The invention relates to the technical field of embedded component installation devices for large and medium-sized equipment foundations of transformer substations, and in particular to an embedded component fixing device for equipment foundations. Background Art

[0002] Since 2016, State Grid Corporation has deepened and strengthened the construction of intelligent power grids and fully implemented modular substation construction. All existing substations have adopted prefabricated substations. However, the foundation and embedded parts of large and medium-sized electrical equipment such as transformers, radiators, and reactors have not changed. Before the reinforced concrete formwork is poured, the embedded parts of the equipment foundation are fixed on the steel bars, and then the concrete is poured. During the pouring stage, the embedded parts are very easy to deform, and their positioning, height, flatness and other precisions may not meet the standards. Moreover, since they are fixed with steel bars, they are not easy to adjust after pouring, and may not meet the installation and use requirements of the equipment. Even after later repairs, their accuracy and aesthetics are greatly affected. Summary of the invention

[0003] In order to effectively solve the problems in the above-mentioned background technology, the present invention proposes a device for fixing embedded parts of equipment foundation.

[0004] The specific technical solutions are as follows:

[0005] A device for fixing embedded parts of an equipment foundation, comprising a first steel pipe, a lead screw, a first nut, a second steel pipe, a channel steel assembly, a second nut, a first steel plate, a vertical channel steel, a screw assembly, a first angle steel, a second angle steel, a third nut and a second steel plate; the middle part of the first steel pipe is fixed to the top of the lead screw, the first nut is threadedly connected to the lead screw, there are two second steel pipes, which are respectively fixed on both sides of the channel steel assembly, the channel steel assembly is installed on the lead screw, the second nut is located below the channel steel assembly and is threadedly connected to the lead screw, the lower part of the first steel plate is fixed to the upper part of the vertical channel steel, a hole is left in the middle of the first steel plate, the lower part of the lead screw passes through the hole, the third nut is fixed to the bottom end of the lead screw, the second steel plate is welded to the bottom of the third nut, the first angle steel and the second angle steel are respectively welded on the front of the lower part of the vertical channel steel, the screw assembly is welded on the first angle steel, and the second angle steel is located below the first angle steel.

[0006] Preferably, the lower two wings of the vertical channel steel are each cut down by 30 mm.

[0007] Preferably, the channel steel assembly includes a transverse channel steel, a fourth nut and a steel bar. A hole is left in the middle of the transverse channel steel for passing the lead screw. The fourth nut and the steel bar are welded on the inner side of the lower part of the transverse channel steel respectively. The steel bars are located on both sides of the fourth nut. The fourth nut is threadedly connected to the lead screw.

[0008] Preferably, the screw assembly includes a screw, a washer, a spring washer, a fifth nut and a third steel plate; the fifth nut is welded inside the first angle steel, the screw is threadedly connected to the fifth nut, the third steel plate is welded to the bottom of the screw, and the washer and spring washer are installed on the screw.

[0009] Compared with the prior art, the beneficial effects of the present invention are: when installing embedded parts, the method of tying and fixing the embedded parts with steel bars is not used, but the device is used to fix the embedded parts. At least two devices are required to fix the embedded parts of each equipment foundation. When the embedded parts are large in size, more devices can be used as appropriate. The device is fixed to the formwork support frame by a horizontal fixing device through a steel pipe to fix the embedded parts on the equipment foundation. After the concrete is poured, if the embedded parts are deformed or displaced, they are adjusted by the height adjustment device and the horizontal adjustment device, which can ensure the implementation effect after completion, and is suitable for large-scale promotion and use in the substation field.

[0016] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, rotated 90 degrees or in other orientations, and the spatially relative descriptions used herein are interpreted accordingly.

[0017] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0018] like Figure 1 As shown, a device for fixing embedded parts of equipment foundation is composed of four parts from top to bottom: a horizontal fixing device, a height adjustment device, a horizontal adjustment device and an embedded part fixing device. The horizontal fixing device fixes the device for fixing embedded parts of equipment foundation to the formwork support frame through a steel pipe to ensure that the embedded parts do not produce horizontal displacement and deformation; the adjustment device can adjust the up and down displacement and horizontal angle of the embedded parts; the embedded part fixing device is used to fix the embedded parts of the equipment foundation.

[0019] Specifically, it includes a first steel pipe 1, a lead screw 2, a first nut 3, a second steel pipe 4, a channel steel assembly 5, a second nut 6, a first steel plate 7, a vertical channel steel 8, a screw assembly 9, a first angle steel 10, a second angle steel 11, a third nut 12, and a second steel plate 13; the middle of the first steel pipe is fixed to the top of the lead screw, the first nut is threadedly connected to the lead screw, there are two second steel pipes, which are respectively fixed on both sides of the channel steel assembly, the channel steel assembly is installed on the lead screw, the second nut is located below the channel steel assembly and is threadedly connected to the lead screw, the lower part of the first steel plate is fixed to the upper part of the vertical channel steel, a hole is left in the middle of the first steel plate, the lower part of the lead screw passes through the hole, the third nut is fixed to the bottom end of the lead screw, the second steel plate is welded to the bottom of the third nut, and the lower two wings of the vertical channel steel are cut down by 30mm each. The first angle steel and the second angle steel are welded to the front of the lower part of the vertical channel steel, the screw assembly is welded on the first angle steel, and the second angle steel is located below the first angle steel.

[0020] like Figure 4 and Figure 5As shown, the channel steel assembly includes a transverse channel steel 51, a fourth nut 52 and a steel bar 53. A hole is left in the middle of the transverse channel steel for passing the lead screw. The fourth nut and the steel bar are welded to the inner side of the lower part of the transverse channel steel respectively. The steel bars are located on both sides of the fourth nut. The fourth nut is threadedly connected to the lead screw.

[0021] like Figure 6 As shown, the screw assembly includes a screw 91, a washer 92, a spring washer 93, a fifth nut 94 and a third steel plate 95; the fifth nut is welded inside the first angle steel, the screw is threadedly connected to the fifth nut, the third steel plate is welded to the bottom of the screw, and the washer and spring washer are installed on the screw.

[0022] The equipment foundation embedded parts fixing device of the present invention is mainly used in substations or other projects that require the installation of large and medium-sized equipment foundation embedded parts. Since the installation and completion accuracy of the steel embedded parts of the large and medium-sized equipment foundation is relatively high, and they need to be cast together with the reinforced concrete foundation to which they are fixed, after the reinforced concrete is cast, the force generated during the concrete solidification process will affect the displacement of the embedded parts. Conventional construction processes cannot achieve accurate fixation of embedded parts, and displacement deviations often occur during the construction phase and cannot be adjusted. The use of the equipment foundation embedded parts fixing device of the present invention can effectively solve and avoid similar problems.

[0023] During the construction of embedded parts of the equipment foundation, two of the present devices can be used for each embedded part of the equipment foundation to fix it to the second angle steel 11 through the embedded part fixing device screw assembly 9. When the size of the embedded part is large, the present device can be added as appropriate to ensure the installation accuracy; then a steel pipe is used to pass through the second steel pipe 4 of the horizontal fixing device of the present device to fix it to the formwork support frame of the equipment foundation to ensure the accuracy of the embedded part position; after the foundation concrete is poured, when the equipment embedded part is displaced or deformed, the horizontal angle and up and down displacement of the embedded part can be adjusted through the first nut 3 and the channel steel assembly 5 of the horizontal adjustment device, and the second nut 6 of the height adjustment device; finally, when the equipment foundation concrete reaches the standard strength grade and the embedded parts of the equipment foundation are adjusted, the present equipment foundation embedded part fixing device can be removed together with the formwork support frame of the equipment foundation, and the equipment foundation embedded parts can perfectly meet the use requirements.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
