Description

Technical Field

[0001] The present invention relates to the fields of substations and converter stations, and more specifically, it is a device base conversion connection device. The present invention also relates to a method for using such a device base conversion connection device. Background Art

[0002] The bases of floor-mounted equipment such as reactors and main transformers are generally a thick steel plate with pre-drilled holes, and are connected to the concrete foundation through embedded anchor bolts; the bases of overhead equipment such as lightning arresters, voltage transformers, and post insulators are also generally a thick steel plate, and are connected to the support top plate through bolts by pre-drilling holes in the steel plate base.

[0003] The embedding accuracy requirements of anchor bolts in the cast-in-place concrete foundation are relatively high. If there are deviations, they cannot be installed, and it is necessary to break the concrete and re-embed the anchor bolts, or return to the factory to replace the equipment base; if there are deviations in the holes of the overhead equipment base, they cannot be installed either, and it is necessary to return to the factory to process the support and top plate or return to the factory to replace the equipment base. However, the equipment base is generally an integral part of the upper structure, and it is difficult to handle even when returning to the factory. The concrete construction has a certain cycle, resulting in high rework costs and long cycles; and in actual situations on site, the concrete foundation and support are often constructed first, and the equipment data is adjusted later, resulting in the situation where installation is impossible.

[0004] Therefore, in order to improve the fault tolerance of design and construction, avoid on-site rework, and improve the efficiency of building construction and equipment installation, it is very necessary to design a device base conversion connection device. Summary of the Invention

Specific embodiments

[0029] The following will describe in detail the implementation of the present invention with reference to the accompanying drawings. However, they do not constitute a limitation to the present invention and are only for illustration purposes. At the same time, the advantages of the present invention will become clearer and easier to understand through the description.

[0030] Referring to the accompanying drawings, it can be seen that a device base conversion connection device is characterized in that it includes a device top plate 1 and a device bottom plate 2 located below the device top plate 1. A first node plate 11 of the top plate is provided on the left side of the bottom of the device top plate 1, and a second node plate 12 of the top plate is provided on the right side of the bottom of the device top plate 1;

[0031] A first node plate 21 of the bottom plate is provided on the left side of the top of the device bottom plate 2, and a second node plate 22 of the bottom plate is provided on the right side of the top of the device bottom plate 2;

[0032] The first node plate 11 of the top plate is telescopically connected to the first node plate 21 of the bottom plate through a first rod member 31, the second node plate 12 of the top plate is telescopically connected to the second node plate 22 of the bottom plate through a first rod member 31, and the first node plate 11 of the top plate is telescopically connected to the second node plate 22 of the bottom plate through a second rod member 32.

[0033] Both the first rod member 31 and the second rod member 32 include a first insertion plate 331, a second insertion plate 332, a first sleeve 341 welded to the first insertion plate 331, a second sleeve 342 welded to the second insertion plate 332, and a threaded rod 35 with one end threadedly connected to the first sleeve 341 and the other end threadedly connected to the second sleeve 342.

[0034] The first top plate gusset 11 and the second top plate gusset 12 are both connected to the first insertion plate 331 by bolts 4, and the first bottom plate gusset 21 and the second bottom plate gusset 22 are both connected to the second insertion plate 332 by bolts 4.

[0035] A method for using a conversion connection device for an equipment base, characterized by comprising the following steps:

[0036] Step 1: Offset the device top plate 1 and the device bottom plate 2 by the telescoping and rotation around the gusset plate of the rod member, so that the equipment base and the foundation or the support top plate can be smoothly installed even if the bolt holes 5 do not correspond.

[0037] Step 2: Threads are provided inside the first sleeve 341, inside the second sleeve 342, and at the end of the threaded rod 35, so that the entire rod member can be freely extended or shortened.

[0038] When the rod member needs to be extended, the threaded rod 35 is rotated out of the sleeve, and when the rod member needs to be shortened, the threaded rod 35 is screwed into the sleeve.

[0039] In actual use, the device top plate 1 and the device bottom plate 2 are used as load-bearing members connecting the upper and lower parts, and are made of steel plates; bolt holes 5 are opened on the device top plate 1 and connected to the equipment base by bolts 4. The size and positioning of the holes on the device top plate 1 must be consistent with those of the equipment base; bolt holes 5 are opened on the device bottom plate 2 and connected to the foundation or the steel support top plate by bolts 4. The holes on the device bottom plate 2 and the anchor bolts on the foundation or the holes on the steel support must be consistent; the size and dimensions of the holes on the device top plate 1 and the device bottom plate 2 can be determined according to the actual situation on site finally, and the sizes of the device top plate 1 and the device bottom plate 2 are determined by comprehensive calculation based on the positioning of the bolt holes 5, the load of the upper equipment, and the size of the internal rod members and gusset plates.

[0040] The gusset plate and the rod member are used to connect the device top plate 1 and the device bottom plate 2 of the device. The offset of the device top plate 1 and the device bottom plate 2 is achieved by the telescoping of the rod member and the rotation around the gusset plate, so as to achieve the purpose that the equipment base and the foundation or the support top plate can be smoothly installed even if the bolt holes 5 do not correspond; threads are provided inside the first sleeve 341, inside the second sleeve 342, and at the end of the threaded rod 35, so that the entire rod member can be freely extended or shortened; when the rod member needs to be extended, the threaded rod 35 is rotated out of the sleeve, and when the rod member needs to be shortened, the threaded rod 35 is screwed into the sleeve. The telescoping length is determined according to the size of the offset required; one side of the gusset plate is welded to the device top plate 1 or the device bottom plate 2, and the other side is connected to the insertion plate at the end of the rod member by bolts, so that the rod member can freely rotate around the bolts in the plane. The size of the gusset plate is determined by calculation according to the actual force.

[0041] The sizes of the bolts 4 are all determined by calculation.

[0042] After installation, the first rod member 31, the second rod member 32, the top plate 1 and the bottom plate 2 form an integral space stable system to firmly fix the equipment on the foundation or the top plate of the bracket. The present invention mainly solves the following technical problems:

[0043] 1) Solve the problem that the equipment base is difficult to install; the present invention is a transition device arranged between the foundation or the top plate of the steel bracket and the equipment base; the bottom plate 2 of the device is connected to the foundation by embedded anchor bolts or connected to the top plate of the steel bracket by bolts, and the top plate 1 of the device is also connected to the equipment base by bolts; even if the openings on the foundation or the bracket top plate and the equipment bottom plate do not correspond, they can be perfectly docked after conversion by this transition device.

[0044] 2) Improve the error tolerance rate; generally, the normal bolt opening size is only 1.5 mm - 2 mm larger than the screw diameter, and almost no deviation is allowed. However, this device can allow a total unidirectional offset of about 250 mm between the foundation or the bracket base and the equipment base by adjusting the middle support rod member; even if there are some adjustments in design or construction, as long as it is within about 250 mm, the requirements can be met.

[0045] 3) Reduce the possible rework cost; if construction errors or equipment data adjustments occur, this device can be added between the foundation or the bracket base and the equipment bottom plate to avoid rework such as demolishing the foundation, replacing the equipment bracket or replacing the equipment base, greatly improving the construction and installation efficiency.

[0046] Determine the offset of the device according to the offset distance between the final equipment on site and the foundation or the bracket top plate, and at the same time adjust and fix it through threads (as Figure 4 and Figure 5 shown).

[0047] Other parts not described belong to the prior art.
