Description

Technical Field

[0001] The utility model relates to the technical field of the installation of box-type substations, in particular to an auxiliary positioning and installation mechanism for a box-type substation. Background Technique

[0002] After the box-type substation (prefabricated substation) arrives at the site through transportation, the overall container of the box-type substation often produces pressure elastic deformation or causes the foundation to be uneven due to the large weight of the transformer; the deformation of the container will cause the chamber doors on the low-voltage and high-voltage sides of the container to be unable to be opened and closed. The inability to open or close the box door will cause the box-type substation to be unable to be used normally: when the box door cannot be opened, it is impossible to enter the cabin to connect the high-voltage and low-voltage side cables; when the box door cannot be closed, it is impossible to achieve the designed dust and waterproof level, and the rain and sand brought by bad weather will erode the box substation and cause damage to its interior, resulting in abnormal use.

[0003] In order to ensure the stability and safety of the box-type substation and prevent equipment damage or operation failures caused by its inclination or imbalance, it is necessary to level the box-type substation during installation. During leveling, it is necessary to lift the box-type substation and use gaskets to pad it under the middle of the container to achieve the leveling effect. However, the box-type substation weighs up to 28 tons and is often placed on a built foundation base (about 100 - 300 mm above the ground), which makes it very difficult to lift the box-type substation.

[0004] The existing methods for lifting the box-type substation include using a jack to lift it or using a crane to lift it. However, due to the very small clearance at the bottom of the box-type substation, its height is less than 20 mm, which makes it difficult to apply the existing jacks; using a crane to lift it will consume a lot of time, the labor cost is expensive, and the leveling effect during the leveling process is not good. The leveling work cannot be completed at one time, and it is necessary to lift and lower it multiple times and check whether the container door can be opened and closed to verify whether the leveling work is completed. Moreover, the existing methods for lifting the box-type substation all have the problems that the box body of the box-type substation is easy to shake and is unstable when it is lifted.

[0013] Optionally, a pin is provided on the support part and / or the connecting part. A ring is provided at the end of the pin, and a chain is connected to the ring. One end of the chain away from the ring is connected to the limit insertion block.

[0014] Optionally, the limit insertion block includes a horizontal plate and a vertical plate.

[0031] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0033] In addition, in the present utility model, descriptions such as "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution where both A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0034] To solve the above technical problems, the present utility model proposes an auxiliary positioning and installation mechanism for a box-type substation, which is applied to the box-type substation. Angle members 10 are provided on the box body of the box-type substation. A cavity 102 is provided inside the angle member 10, and a waist-shaped positioning through hole 101 communicating with the cavity 102 is provided on the side wall of the angle member 10. The auxiliary positioning and installation mechanism includes: a support member 20, the support member 20 includes a support portion 201 and a connecting portion 202. The connecting portion 202 is connected to one end of the support portion 201. An insertion shaft 21 is provided on the end face of the connecting portion 202 away from the support portion 201, and a clamping portion 22 is provided at one end of the insertion shaft 21 away from the connecting portion 202; the shape and size of the clamping portion 22 match those of the waist-shaped positioning through hole 101, and the clamping portion 22 is provided with an abutting surface 221, and the abutting surface 221 protrudes outward along the radial direction of the insertion shaft 21, so that the clamping portion 22 passes through the waist-shaped positioning through hole 101 at an angle and inserts into the cavity 102; and after the clamping portion 22 rotates in the cavity 102 with the axis of the insertion shaft 21 as the rotation center, the abutting surface 221 abuts against the wall surface of the cavity 102; the support portion 201 is used to connect with the output end of the jack 30 to lift the support member 20; a limit insertion block 40 is movably connected to the support portion 201 and / or the connecting portion 202, and the limit insertion block 40 is used to insert into the gap between the connecting portion 202 and the box body. Refer to Figures 1 to 5 。

[0035] When this embodiment is in use, first rotate the support member 20 until the shape of the clamping portion 22 matches the shape of the waist-shaped positioning through hole 101, so that the clamping portion 22 passes through the waist-shaped positioning through hole 101 and inserts into the cavity 102 of the angle member 10. Then rotate the support member 20 so that the clamping portion 22 rotates a certain angle (where this angle is not 0°, 180°, or 360°) around the axis of the insertion shaft 21 in the cavity 102. When the rotation angle is 0°, the shape of the clamping portion 22 corresponds to that of the waist-shaped positioning through hole 101, and at this time the clamping portion 22 can pass through the waist-shaped positioning through hole 101. Since the shape of the waist-shaped positioning through hole 101 is symmetrical, when the rotation angle is 180° or 360°, the shape of the clamping portion 22 also corresponds to that of the waist-shaped positioning through hole 101, and at this time the clamping portion 22 can also pass through the waist-shaped positioning through hole 101. The abutting surface 221 abuts against the wall surface of the cavity 102, so that the clamping portion 22 and the waist-shaped positioning through hole 101 are mutually clamped. Specifically, the rotation angle is preferably 90°. It should be noted that the jack 30 is generally directly placed on the ground. When in use, first rotate the support member 20 to complete the installation of the clamping portion 22 and the waist-shaped positioning through hole 101 on the angle member 10, and then complete the installation of the support member 20 and the jack 30. Since there will be a gap between the connecting portion 202 of the support member 20 and the box-type substation body after the clamping portion 22 and the angle member 10 are clamped, finally, the limit insert block 40 needs to be inserted into the gap between the connecting portion 202 and the box-type substation body, so that the two end surfaces of the limit insert block 40 respectively fit the connecting portion 202 and the column of the box-type substation body, avoiding the shaking of the auxiliary positioning and installation mechanism, and thus avoiding the phenomenon of shaking when the box-type substation rises and falls. It should be noted that after the clamping portion 22 and the waist-shaped positioning through hole 101 are clamped, there is a gap between the insertion shaft 21 and the waist-shaped positioning through hole 101 in the height direction. This gap is used to enable the position of the insertion shaft 21 to be finely adjusted up and down along the waist-shaped positioning through hole 101, that is, the position of the support member 20 can be finely adjusted up and down along the waist-shaped positioning through hole 101, which is convenient for arranging the jack 30 below the support member 20 and making the output end of the jack 30 movably connected to the support member 20 to lift the support member 20.

[0036] In the present utility model, the clamping portion 22 can be inserted into the interior of the corner fitting 10, and by rotating the support member 20, the clamping portion 22 can be engaged with the corner fitting 10. The structure is simple and practical. Through simple installation, the effective locking of the support member 20 and the corner fitting 10 can be achieved. At the same time, when in use, the clamping portion 22 extends into the cavity 102 of the corner fitting 10, which can play a role in fixing and force-bearing extension, effectively improving the stability of the connection between the support member 20 and the corner fitting 10, and avoiding the clamping portion 22 falling off from the waist-shaped positioning through-hole 101 when the box-type substation is lifted. By providing the limit insertion block 40 to be inserted into the gap between the connecting portion 202 and the box body, it is ensured that the auxiliary positioning and installation mechanism of the box-type substation of the present utility model is closely attached to the box-type substation, effectively avoiding shaking when the box-type substation is lifted and improving the stability.

[0037] The present utility model has a lifting and transfer function. Its structure is simple and practical, can be simply installed on a container, and can cooperate with an existing hydraulic jack to complete the lifting work of the box-type substation. It has high operation efficiency, and has the advantages of low design and manufacturing cost, light weight, small volume, easy to carry and transport, etc. It effectively solves the problems of difficult and low-efficiency lifting of the box-type substation, and easy shaking and instability of the box body when the box-type substation is lifted, improves the leveling efficiency of the box-type substation, and thus improves the overall efficiency of on-site installation of the box-type substation.

[0038] Refer to Figures 5 to 9 , in this embodiment, the long axis of the waist-shaped positioning through-hole 101 is perpendicular to the horizontal plane, and the short axis of the waist-shaped positioning through-hole 101 is parallel to the horizontal plane; the long axis of the clamping portion 22 is parallel to the horizontal plane, and the short axis of the clamping portion 22 is perpendicular to the horizontal plane.

[0039] In the above embodiment, it should be noted that when the long axis of the clamping portion 22 is parallel to the horizontal ground and the short axis is perpendicular to the horizontal ground, at this time, the surface of the support member 20 connected to the output end of the jack 30 faces the horizontal ground. When the clamping portion 22 and the waist-shaped positioning through-hole 101 are in a clamped state, the clamping portion 22 and the waist-shaped positioning through-hole 101 are clamped to form a cross-shaped intersection. The cross-shaped structure can effectively disperse the force, making the insertion shaft 21 and the clamping portion 22 bear the pressure more evenly, reducing local stress concentration, and effectively improving the stability of the connection between the support member 20 and the corner fitting 10.

[0040] It should be noted that the corner fitting 10 is arranged at the corners of the bottom of the box-type substation (the box-type substation and its box part are not shown in the figure). Of course, the corner fitting 10 can be arranged at the four corners of the bottom of the box, or only at two adjacent corners of the bottom of the box; among them, waist-shaped positioning through holes 101 can be arranged on the four side walls of the corner fitting 10, so that the auxiliary positioning and installation mechanism can be inserted into the corner fitting 10 from different directions. Preferably, waist-shaped positioning through holes 101 are respectively arranged on two adjacent side walls of the corner fitting 10 facing the outside, so that the auxiliary positioning and installation mechanism can be inserted into the corner fitting 10 from two directions respectively, improving the flexibility of use.

[0041] Refer to Figures 3 to 4 , the connecting part 202 protrudes downward from the supporting part 201, and an avoidance space 203 for placing the output end of the jack 30 is formed between the supporting part 201 and the connecting part 202.

[0042] In the above embodiment, an avoidance space 203 for placing the output end of the jack 30 is formed between the supporting part 201 and the connecting part 202, making the structure more compact during use.

[0043] Refer to Figure 6 , in this embodiment, a limiting hole 2011 is provided on the end face of the supporting part 201 facing the avoidance space 203, and the output end of the jack 30 is limitedly connected in the limiting hole 2011.

[0044] It should be noted that in the above embodiment, after the clamping part 22 is clamped with the waist-shaped positioning through hole 101, in the height direction, there will be a gap between the insertion shaft 21 and the waist-shaped positioning through hole 101. This gap is used to finely adjust the position of the insertion shaft 21 up and down along the waist-shaped positioning through hole 101, that is, the position of the support member 20 can be finely adjusted up and down along the waist-shaped positioning through hole 101, facilitating the setting of the jack 30 below the support member 20. Through the setting of the limiting hole 2011, the output end of the jack 30 is limited to move in the height direction, avoiding the position deviation of the jack 30 in the horizontal direction and effectively improving the connection stability between the jack 30 and the support member 20.

[0045] Refer to Figures 1 to 2 , in this embodiment, the cross-sectional shape of the supporting part 201 in the height direction is semi-circular, and the end face of the supporting part 201 facing the avoidance space 203 is a plane parallel to the horizontal plane.

[0046] The semi-cylindrical support member 20 has high stability and strong load-bearing capacity. When bearing vertical and horizontal loads, it can effectively disperse stress, and is not prone to deformation or damage when bearing a large weight. Moreover, it is convenient to form an avoidance space 203 for placing the output end of the jack 30 between the support portion 201 and the connecting portion 202.

[0047] Refer to Figures 6 to 7 , in this embodiment, the cross-sectional shape of the connecting portion 202 in the height direction is circular.

[0048] It should be noted that by setting the cross-sectional shape of the connecting portion 202 in the height direction to be circular, the force on the connecting portion 202 is more uniform, avoiding stress concentration, thereby improving the overall stability and durability of the structure. The connecting portion 202 and the support portion 201 can be integrally formed, making its rotation more flexible.

[0049] Refer to Figure 6 , in this embodiment, the support portion 201 and the connecting portion 202 are of an integrally formed structure.

[0050] By setting the support portion 201 and the connecting portion 202 to be of an integrally formed structure, the number of connection points is reduced, thereby reducing the risk of failure caused by the loosening or breakage of the connection points, effectively improving the stability and service life of the structure, and reducing the manufacturing and assembly steps of two separate components, thus simplifying the entire manufacturing process.

[0051] Refer to Figure 1 , in this embodiment, the support portion 201 and / or the connecting portion 202 are provided with a pin 41. The end of the pin 41 is provided with a ring 42, and the ring 42 is connected with a chain 43. The end of the chain 43 away from the ring 42 is connected with the limit plug 40.

[0052] It should be noted that the length of the chain 43 should be such that the limit plug 40 can move and be inserted into the gap between the connecting portion 202 and the box body. In this embodiment, the limit plug 40 is fixed on the support member 20 by means of the chain 43. When the limit plug 40 is needed, it can be moved and inserted into the gap between the connecting portion 202 and the box body to ensure that the auxiliary positioning and installation mechanism of the box-type substation is closely attached to the box-type substation, avoiding the shaking of the auxiliary positioning and installation mechanism, effectively preventing the box-type substation from shaking when it is lifted, and improving the stability. After use, the limit plug 40 can be directly pulled out, avoiding the loss of the limit plug 40 parts. Further, the ring 42 and the chain 43 are fixed by welding. Further, multiple chains 43 can be provided on the ring 42, and different specifications of limit plugs 40 are connected to each chain 43, so as to be adapted to box-type substation boxes of various different specifications, improving the practicability and adaptability of the present invention.

[0053] Referring to Figure 1 , in this embodiment, the limit insertion block 40 includes a horizontal plate 401 and a vertical plate 402. A pin seat 403 is provided on the upper surface of the horizontal plate 401. The pin seat 403 is movably connected to the chain 43. The vertical plate 402 extends downward and is arranged on one side of the horizontal plate 401, and the vertical plate 402 is perpendicular to the horizontal plate 401.

[0054] By designing the limit insertion block 40 to include a horizontal plate 401 and a vertical plate 402, the vertical plate 402 extends downward and is arranged on one side of the horizontal plate 401 and is perpendicular to the horizontal plate 401. The vertical plate 402 is used to insert into the gap between the connecting portion 202 and the box body. The horizontal plate 401 can serve as a handle, making it more convenient to insert and pull out the vertical plate 402, and can avoid the connection between the chain 43 and the limit insertion block 40 from breaking when pulling out the limit insertion block 40, thus preventing the situation where the limit insertion block 40 cannot be pulled out.

[0055] Referring to Figure 1 , in this embodiment, an inclined surface portion 4021 is provided at the lower end of the vertical plate 402, and the inclined surface portion 4021 faces the connecting portion 202.

[0056] By providing the inclined surface portion 4021 at the lower end of the vertical plate 402, it is beneficial to make the vertical plate 402 more easily insert into the gap between the connecting portion 202 and the box body.

[0057] Preferably, in this embodiment, the jack 30 is a hydraulic jack. Among them, a common small hydraulic jack on the current market can be used for the hydraulic jack, solving the problem that it is impossible to use a small hydraulic jack to lift the box-type substation due to the small gap at the bottom of the box-type substation.

[0058] Preferably, in this embodiment, the materials of the support portion 201, the connecting portion 202, the insertion shaft 21, and the clamping portion 22 are all Q345 steel, making the support portion 201, the connecting portion 202, the insertion shaft 21, and the clamping portion 22 have the advantages of high strength, good welding performance, and strong corrosion resistance.

[0059] The working process of the present utility model is as follows:

[0060] Rotate the supporting member 20 until the shape of the clamping portion 22 matches the shape of the waist-shaped positioning through hole 101, so that the clamping portion 22 passes through the waist-shaped positioning through hole 101 and extends into the cavity 102 of the angle member 10. Then rotate the supporting member 20 so that the clamping portion 22 rotates a certain angle around the axis of the insertion shaft 21 in the cavity 102 and then engages with the waist-shaped positioning through hole 101. Fine-tune the position of the supporting member 20 upward along the gap between the waist-shaped positioning through hole 101 and the insertion shaft 21. Place a jack 30 below the supporting member 20 so that the output end of the jack 30 is limited and fitted in the limiting hole 2011 of the supporting member 20. Insert the limiting plug 40 into the gap between the connecting portion 202 and the box body of the box-type substation to prevent the box-type substation from shaking when it is lifted and lowered. At this time, repeat the above steps to install another set of auxiliary positioning and installation mechanisms of the box-type substation into the angle member 10 on the adjacent side of the bottom of the box body. Lift and lower the box-type substation using the jack 30 according to the actual installation height on site, and place appropriate pads under the box body of the box-type substation. Finally, use the jack 30 to lower the box body again. Thus, the process of lifting and lowering the box-type substation is completed.

[0061] The utility model solves the problems of difficult lifting of the box-type substation, easy shaking and instability of the box body when the box-type substation is lifted. Moreover, the structure is simple and practical, the installation is simple, it is convenient to carry, light in weight and small in volume, and it can cooperate with the existing hydraulic jack to complete the lifting work of the box-type substation. The operation efficiency is high, effectively improving the leveling efficiency of the box-type substation, so that the work can be completed by only 1-2 people, and the completion time is within 10 minutes (for 1 unit), thereby improving the overall efficiency of on-site installation of the box-type substation.

[0062] The above are only the preferred embodiments of the utility model, and do not limit the patent scope of the utility model. All equivalent structural transformations made under the inventive concept of the utility model by using the content of the specification and drawings of the utility model, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the utility model.
