Description

Technical Field

[0001] This utility model relates to the field of substation technology, specifically to a sliding rail bottom support plate and a box-type substation using the same. Background Technology

[0002] The bottom support structure of a prefabricated substation needs to balance stability and adjustability. The slide rail, as a core component, facilitates the position adjustment of the prefabricated unit through lateral guidance, aiding in installation, maintenance, and layout optimization. However, existing slide rail support structures suffer from the following technical defects, limiting their practical application:

[0003] To fully support the weight of the enclosure and ensure stability during movement, the length of traditional sliding rails is usually close to or exceeds the length of the support plate. However, after the prefabricated substation is moved laterally, a large area of ​​the sliding rails is exposed on the outside of the foundation, which not only ruins the overall aesthetics of the site but also creates safety hazards such as tripping and bumping, especially in sidewalks or areas with dense equipment. If the sliding rails are shortened to reduce the exposed part, the support plate may be partially suspended when the prefabricated substation is moved, which will significantly reduce the structural stability and may easily lead to enclosure tilting, sliding rail deformation, or local pressure damage to the foundation in the long run.

[0004] Therefore, this utility model proposes a sliding rail type bottom support plate and a box-type substation using it. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a sliding rail bottom support plate and a prefabricated substation using the same. Through a dynamic compensation mechanism of "short sliding rail + traveling wheels," the sliding rail bottom support plate and the prefabricated substation using the same achieve breakthroughs in structural stability and site adaptability while maintaining the guiding accuracy of traditional long sliding blocks. This provides technical support for the widespread application of prefabricated substations in smart cities, temporary power supply, and other fields.

[0029] As shown in Figs. Figure 1 and Figure 2 , the sliding rail type bottom support plate is mainly used for stably installing the box-type substation box 2 on the concrete foundation 1, and facilitates adjustment and movement of the box body; through the cooperation of the short sliding rail and the walking wheel, safe, stable and convenient movement of the support plate is realized.

[0030] The sliding rail type bottom support plate comprises a support plate body 3, a walking wheel 4, a sliding rail 5 and a sliding block 6.

[0031] Two parallel and opposite sliding rails 5 are fixedly installed on the concrete foundation 1, and the length of the sliding rail 5 is less than half the length of the support plate body 3.

[0032] A sliding groove 5d is arranged at the upper portion of the sliding rail 5, and a sliding block 6 matched with the sliding groove 5d is arranged at the bottom of the support plate body 3, the sliding block 6 is centrally arranged at the bottom of the support plate body 3 along the length direction, and the length of the sliding block 6 is greater than half the length of the support plate body 3.

[0033] ​​The bottom of the sliding groove 5d is provided with a wheel groove 5e, and the bottom of the wheel groove 5e is at the same level as the concrete foundation 1.

[0034] The walking wheels 4 are arranged at the four corners of the support plate body 3, and the maximum size of the outer contour of the walking wheels 4 is smaller than the width of the wheel groove 5e. The walking wheels 4 can be selected from the commonly used universal casters with brake devices on the market.

[0035] As shown in Figure 3 and Figure 4 Each sliding rail 5 is composed of two half sliding rail strips 5a, which are fixed on the concrete foundation 1 in parallel and opposite directions, and the middle of the two half sliding rail strips 5a forms a sliding groove 5d and a wheel groove 5e.

[0036] The half sliding rail strip 5a is fixed on the concrete foundation 1 by a bolt 5b, and the bolt 5b is an expansion bolt. The expansion bolt has good anchoring performance, which can ensure that the sliding rail is stably fixed on the concrete foundation, and avoid loosening of the sliding rail due to vibration or external force.

[0037] The length of the sliding rail 5 is less than half the length of the support plate body 3. For example, when the length of the support plate body 3 is 2000mm, the length of the sliding rail 5 can be designed as 800mm. In this way, the exposed part of the sliding rail is significantly reduced, effectively solving the safety hazard and landscape coordination problem of the sidewalk and municipal area.

[0038] A sliding block 6 is arranged at the bottom of the support plate body 3 in the middle along the length direction, and the length of the sliding block 6 is greater than half the length of the support plate body 3. For example, when the length of the support plate body 3 is 2000mm, the length of the sliding block 6 can be designed as 1200mm. In this way, the sliding block 6 can fully cooperate with the sliding groove 5d on the sliding rail 5, ensuring the stable sliding of the support plate body 3 on the sliding rail 5.

[0039] The sliding block 6 tightly cooperates with the sliding groove 5d on the sliding rail 5, ensuring that the support plate body 3 will not be skewed or stuck during movement. The material of the sliding block 6 can be selected from wear-resistant and corrosion-resistant materials such as nylon or polytetrafluoroethylene to prolong the service life.

[0040] The walking wheels 4 are arranged at the four corners of the support plate body 3, and the maximum size of the outer contour of the walking wheels 4 is smaller than the width of the wheel groove 5e. For example, when the width of the wheel groove 5e is 50mm, the maximum size of the outer contour of the walking wheels 4 can be designed as 45mm. In this way, the walking wheels 4 can freely roll in the wheel groove 5e without falling out of the wheel groove 5e.

[0041] The walking wheel 4 serves as a "moving fulcrum". When the box-type substation box 2 moves to the end of the slide rail 5, the walking wheel 4 automatically shares the load and compensates for the overhanging effect that may be caused by the short slide rail. The material of the walking wheel 4 can be high-strength and wear-resistant rubber or plastic to ensure its load-carrying capacity and service life.

[0042] A support plate locking device is arranged on the slide rail 5, which includes a set screw 5c. A set screw hole is arranged on the half slide rail strip 5a, and the set screw 5c is installed in the set screw hole through thread cooperation. By turning the set screw 5c, the end of the set screw 5c is close to or away from the sliding block 6, so as to realize the locking or loosening of the support plate body 3. When it is necessary to adjust the position of the box-type substation box 2, the set screw 5c is loosened, so that the support plate body 3 can freely slide on the slide rail 5; after adjustment, the set screw 5c is tightened to firmly lock the support plate body 3 on the slide rail 5.

[0043] The set screw hole can be arranged at the middle position of the half slide rail strip 5a, or at the end position of both ends. When arranged at the middle position, the support plate body 3 can be locked as a whole; when arranged at the end position of both ends, the two sides of the support plate body 3 can be respectively locked, improving the flexibility of locking.

[0044] End blocks 6a are arranged at both ends of the sliding block 6. The material of the end blocks 6a can be the same wear-resistant and corrosion-resistant material as the sliding block 6, such as nylon or polytetrafluoroethylene. The end blocks 6a can effectively prevent the support plate body 3 from completely coming out of the slide rail 5. When the support plate body 3 moves to the end of the slide rail 5, the end blocks 6a will contact the end of the slide rail 5, preventing the support plate body 3 from continuing to move, thereby avoiding the support plate body 3 from falling off the slide rail 5, and improving the safety of the equipment.

[0045] The slide rail type bottom support plate and the box-type substation applying the same reduce the exposure of the slide rail: the traditional long slide rail design will cause a large amount of slide rail to be exposed, which not only affects the safety of the sidewalk and the municipal area, but also is not coordinated with the surrounding environment. The length of the slide rail is shortened to less than 50% of the length of the support plate body in the utility model, and the exposed part is reduced by more than 60%. For example, when the length of the support plate body is 2000mm, the length of the traditional slide rail may be 1800mm, and the exposed part is relatively long; while the length of the slide rail of the utility model can be designed as 800mm, and the exposed part is significantly reduced, thereby completely solving the safety hazard and landscape coordination problem of the sidewalk and the municipal area.

[0046] The slide rail type bottom support plate and the box-type substation applying the same improve safety: the short slide rail design reduces the risk of collision between pedestrians or vehicles and the slide rail, improving the safety of the equipment. At the same time, the setting of the walking wheel makes the box-type substation box more stable during movement, further reducing the safety risk.

[0047] When the box-type transformer station box moves to the end of the slide rail, the support plate body may be suspended due to the short length of the slide rail. The walking wheels arranged at the four corners of the support plate body can cooperate with the wheel grooves on the slide rail to form a "moving fulcrum", automatically share the load and compensate the suspension effect caused by the short slide rail. In this way, even if the support plate body is partially suspended, the walking wheels can provide stable support to ensure the overall stability of the box-type transformer station.

[0048] The support plate locking device arranged on the slide rail is locked and loosened by a set screw. The set screw can firmly lock the support plate body on the slide rail to prevent it from moving under the action of external forces such as wind and vibration, and the design of the locking device improves the stability of the box-type transformer station during use.

[0049] The set screw hole can be arranged at different positions of the half slide rail strip, which can be locked integrally at the middle position or locked separately at the two end positions. This design improves the flexibility of locking and facilitates adjustment according to different use requirements.

[0050] The stoppers arranged at both ends of the sliding block can effectively prevent the support plate body from completely coming out of the slide rail. The contact between the stopper and the end of the slide rail prevents the support plate body from moving further, ensuring that the equipment is always within a safe range, and the design of the stopper improves the anti-disengagement reliability of the equipment.

[0051] The slide rail type bottom support plate and the box-type transformer station applying the same realize the breakthrough of structural stability and site adaptability on the premise of maintaining the traditional long slide block guiding precision through the dynamic compensation mechanism of "short slide rail + walking wheel", which provides technical support for the wide application of the box-type transformer station in the field of smart city and temporary power supply.
