Description

Technical Field

[0001] This utility model relates to the field of substation assembly technology, and in particular to an assembly structure for prefabricated substations. Background Technology

[0002] Traditional prefabricated substation assembly methods typically involve lifting the top cover of the casing and using cranes or other equipment to hoist and position components such as high- and low-voltage switchgear and transformers sequentially from the top of the casing. However, with the increasing diversity of usage requirements and environmental conditions for prefabricated substations, traditional assembly methods are no longer suitable for certain assembly scenarios. These include situations involving non-open-top structures such as standard container casings and casings with suspended ceilings, insufficient assembly space above the product, and the requirement for simultaneous assembly of multiple integrated cabinets. Therefore, there is an urgent need for an assembly structure that can assist in the entry of components from the side of the casing.

[0003] To address this, we designed an assembly structure for prefabricated substations. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model discloses an assembly structure for a prefabricated substation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An assembly structure for a prefabricated substation, characterized in that it includes:

[0007] The slide rails are arranged in parallel at intervals, with a guide groove with an open top on the top surface and multiple height-adjustable pads spaced at intervals along the bottom along the axial direction.

[0008] The slide plate has sliding parts embedded in the guide groove at both ends;

[0009] A top support is provided on the lower surface of the slide plate and is used to drive the slide plate to detach from the slide rail and rise.

[0010] The raised block includes:

[0011] The first piece is located at the bottom of the slide rail. The bottom surface of the first piece is an inclined adjustment slope, and the adjustment slope is provided with a sliding groove.

[0012] The second block has a top surface that matches the adjustment ramp and has a sliding protrusion that is embedded in the groove; the side wall of the second block has an L-shaped extension with a vertical strip hole.

[0013] An adjusting screw is rotatably connected at one end to the side wall of the first block, and a threaded slider is threadedly fitted to the screw body. The threaded slider is slidably connected to the strip hole. By rotating the adjusting screw, the second block is driven to move along the slide groove, so that the first block can make vertical lifting and lowering movements under the cooperation of the adjusting inclined surface and the mating inclined surface.

[0014] Furthermore, the inclination direction of the adjusting inclined surface and the mating inclined surface is perpendicular to the axis of the slide rail.

[0015] Furthermore, the sliding part is provided with a roller that rolls in cooperation with the guide groove.

[0016] Furthermore, the slide rail has a segmented structure, and adjacent slide rail segments are connected by an axial engagement limiting structure, which is an inverted L-shaped protrusion and groove mating structure.

[0017] Furthermore, the bottom of the slide rail is provided with a receiving groove, and the top surface of the first block is provided with a fixing block that is embedded in the receiving groove.

[0018] Furthermore, one of the slide rail sections has a limiting block at its end that is embedded in the receiving groove of another slide rail section, forming a lateral limiting structure.

[0019] Furthermore, the cross-section of the groove is T-shaped, and the cross-section of the sliding protrusion is a dovetail-shaped structure that matches the T-shaped groove.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] By using the sliding plate and the slide rail, the assembly components can be entered from the side opening of the substation shell, and with the help of the top support, the assembly components can be moved to the pre-installation position.

[0022] 2. The raised block adopts an inclined plane-screw linkage mechanism. By rotating the adjusting screw, the second block is driven to move horizontally, which is converted into the vertical lifting and lowering of the first block, so as to realize the adjustment of the slide rail height and adapt to complex ground conditions.

[0023] 3. The slide rail adopts a segmented structure. Through the axial engagement and lateral limiting structure of the inverted L-shaped protrusion and groove, adjacent slide rail segments are doubly fixed axially and laterally, ensuring the overall stability after splicing. It is suitable for scenarios with frequent disassembly or long-distance installation. Attached Figure Description

[0033] An assembly structure for a prefabricated substation includes:

[0034] Slide rail 1 assembly: combined with attached Figure 1-3 The slide rail 1 has a segmented structure, consisting of multiple slide rail segments 12 connected by an axial engagement and limiting structure 121. The axial engagement and limiting structure 121 uses an inverted L-shaped protrusion and groove to ensure that adjacent slide rail segments 12 can be quickly engaged and fixed when axially aligned. The top surface of the slide rail 1 has a guide groove 11 with an open upper end, i.e., the cross-section of the guide groove 11 is U-shaped, used to accommodate the sliding part 31 of the slide plate 3. Multiple shims 2 are spaced axially along the bottom of the slide rail 1 to adjust the overall height of the slide rail 1.

[0035] Furthermore, in conjunction with the appendix Figure 3 and 7 Each slide rail segment 12 is also provided with a receiving groove 13 at its bottom. The ends of adjacent slide rail segments 12 form a lateral limiting structure through the cooperation of the limiting block 122 and the receiving groove 13, preventing adjacent slide rail segments 12 from shifting in the lateral direction. Furthermore, the limiting block 122 is located inside the L-shaped groove.

[0036] Elevation block 2: Combined with attached Figure 4-6 It consists of a first block 21, a second block 22 and an adjusting screw 23.

[0037] The first block 21 is located at the bottom of the slide rail 1, and its bottom surface is an inclined adjustment slope 211. The adjustment slope 211 is provided with a T-shaped groove 212. Furthermore, the top surface of the first block 21 is fixed by a fixing block 213 embedded in the receiving groove 13.

[0038] The second piece 22 has a top surface that matches the adjusting inclined surface 211 with a sliding protrusion 222 of a dovetail cross-section, which is embedded in the sliding groove 212 to achieve a sliding fit. The side wall of the second piece 22 has an L-shaped extension 223 with a vertical strip hole 224.

[0039] Adjusting screw 23: One end is rotatably connected to the side wall of the first block 21 via a bearing, and the screw body is threadedly engaged with the threaded slider 231. The threaded slider 231 is embedded in the slotted hole 224, and rotating the adjusting screw 23 drives the second block 22 to slide along the slide groove 212. Since the inclination direction of the adjusting inclined surface 211 and the mating inclined surface 221 is perpendicular to the axis of the slide rail 1, the horizontal movement of the second block 22 can be converted into the vertical lifting and lowering of the first block 21, thereby achieving precise adjustment of the height of the slide rail 1.

[0040] Skateboard 3: Combined with attachments Figure 1-2 The slide plate 3 has sliding parts 31 at both ends, which are embedded in the guide grooves 11 of the slide rail 1. Rollers 311 are mounted on the sliding parts 31, and the rollers 311 roll in contact with the inner wall of the guide grooves 11 to reduce frictional resistance when the slide plate 3 moves. A top support 4 is mounted on the lower surface of the slide plate 3. The top support 4 can be a hydraulic cylinder or an electric push rod. When the slide plate 3 moves to the target position, the top support 4 is activated, driving the slide plate 3 to detach from the slide rail 1 and rise, so that the assembly component can be pushed into the installation position from the side.

[0041] Assembly process:

[0042] 1. Install slide rail 1: Based on the dimensions of the substation casing, multiple slide rail sections 12 are spliced ​​together into a complete slide rail 1 using the axial locking and limiting structure 121. One end of the slide rail 1 is then inserted into the substation casing through the side opening, and the height of the slide rail 1 is adjusted according to the desired height. It should be noted that the slide rail sections 12 can also be installed sequentially from the inside out and spliced ​​together to form a complete slide rail 1. Specifically, adjusting the height of the slide rail 1 involves rotating the adjusting screws 23 of each shim block 2 to level the slide rail 1 to the preset height.

[0043] 2. Positioning of the slide plate 3: Insert the sliding part 31 of the slide plate 3 into the guide groove 11, then place the assembly part on the slide plate 3, and push the slide plate 3 along the slide rail 1 to the target area.

[0044] 3. Lifting and installation: Activate the top support 4 to lift the sliding plate 3 to the required height, and then lift the assembly components to the appropriate height to complete the installation.
