Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformer repair and maintenance tools, in particular to a large-scale transformer repair rail platform. Background Art
[0002] The transformer in the large transformer room of the power station is installed on the rails through the rail wheel seat. The lower area of the large transformer, that is, on both sides of the rails, is paved with pebbles. The pebbles have the functions of oil seepage and flame retardancy. However, when the transformer is overhauled, people step on the pebbles, which is not convenient for maintenance work and easily causes the operators to slip. At present, during maintenance, the template is laid on the pebbles, which is convenient for walking, but because the pebbles are uneven, the laid template is also unstable. In addition, due to the high height of the large transformer, it is necessary to set up a steel pipe scaffolding during maintenance. The longitudinal rods of the steel pipe scaffolding are also supported on the pebbles by wooden squares. In order to avoid the longitudinal rods of the steel pipe scaffolding, the template cannot be laid in one piece, which further reduces the stability of the template. In addition, after the maintenance is completed, the template and steel pipe scaffolding need to be dismantled, and the dismantled template and steel pipe are manually carried out of the transformer room, which is labor-intensive.

DETAILED DESCRIPTION
[0020] See also Figure 1-5A large transformer maintenance rail platform includes a grid plate 1, two opposite sides of the grid plate 1 are respectively installed with slide bars 2, and the slide bars 2 on both sides are respectively installed with support members extending outward, and the support members include a slider 3, an extension seat 4 and an auxiliary part. The slider 3 is directional slidingly connected with the slide bar 2, one end of the extension seat 4 is connected to the slider 3, and the other end is provided with the auxiliary part, and the auxiliary part includes a limit groove 5 or a roller structure 6. During maintenance, support members with limit grooves are installed on the slide bars on both sides of the grid plate, so that the grid plate can be supported and positioned on the rails, and the stability is good. After the maintenance is completed, the support member with the limit groove is replaced with a support member with a roller structure, so that the transportation of materials such as templates and steel pipes can be assisted, and the labor intensity is reduced.
[0021] The grille plate 1 is a metal grille, and the length and width of the grille hole are greater than the diameter of the steel pipe. Specifically, the diameter of the steel pipe is 48mm, and the length and width of the grille hole are 50mm*50mm. In this way, after the grille net 1 is installed on the rail 8, the longitudinal rod of the steel pipe scaffolding can still pass through the grille net 1. Since the grille net 1 is suspended by the support, the bottom can be conveniently placed with wooden blocks.
[0022] Since the transformer is installed on the rail wheel seat, there will be interference between the rail wheel and the rail 8 on which the grid net 1 is placed. Therefore, the support member is connected to the slide bar 2 in a directional sliding manner, so that the position of the support member can be flexibly adjusted to avoid the rail wheel. At the same time, the support member is extended outward, so that there is a large gap between the grid net 1 and the rail 8, which also provides space for avoiding the rail wheel. Figure 5 The adjustable sliding of the support also facilitates the installation of the grille 1 side by side, so that there is no interference between the left and right support members.
[0023] See also Figure 2 Specifically, the upper and lower sides of the slide bar 2 are respectively provided with slide grooves 21, the slide block 3 is a C-shaped structure, and the two ends of the opening side of the slide block 3 are respectively located in the slide grooves 21 on the upper and lower sides. Through the above structure, the directional sliding adjustment of the support member is achieved.
[0024] Of course, the slide bar 2 may also be a rectangular rod, and the height of the slide bar 2 exceeds the thickness of the grille mesh 1 , so that the slider 3 of the C-shaped structure can also be connected to the slide bar 2 in a directional sliding manner.
[0025] The slide bar 2 can be welded to the grid mesh 1. In a preferred solution, a plurality of countersunk bolt holes 22 are provided on the slide bar 2, and screws are inserted into the countersunk bolt holes 22 and then screwed to the grid plate 1. In this way, the grid mesh 1 can be replaced according to the width between the rails.
[0026] Furthermore, the slider 3 is provided with a threaded hole 31, the limit screw 7 is screwed to the threaded hole 31, and the threaded end of the limit screw 7 abuts against the slide bar 2 to limit the slider 3 and the slide bar 2. Preferably, the limit screw 7 is a hand screw.
[0027] In a preferred embodiment, see Figure 3 The limiting groove 5 is formed by two baffles 51 welded on the lower side of the extension seat 4. Of course, the limiting groove 5 can also be a notch opened on the lower side of the extension seat 4.
[0028] In a preferred embodiment, see Figure 4 The roller structure 6 is a caster. The caster is welded or bolted to the lower side of the extension seat 4. Of course, the roller structure 6 can also be a rail wheel, so that it can move on the rails on the lower side of the transformer, and the rail wheel is installed on the lower side of the extension seat 4 through a matching bracket.
[0029] See also Figure 1 , 2 The other two sides of the grid plate 1 are respectively provided with connection holes 11, so that the multiple grid nets 1 installed along the rails 8 can be bolted and fixed in sequence.
[0030] The working principle or action process of the utility model is as follows:
[0031] When in use, the support member is connected to the slide bar 2 by directional sliding cooperation, so that the position of the support member can be flexibly adjusted to avoid the rail wheel, so that the grid plate 1 can be laid and installed on the rail in sequence, such as Figure 5 In addition, the plurality of grid nets 1 installed along the length direction of the rail 8 are bolted and fixed in sequence through the connection holes 11. When the steel pipe scaffold is installed, the longitudinal rods of the steel pipe scaffold pass through the grid net 1.
[0032] After the inspection is completed, the scaffolding and the grille net 1 are removed, the support with the limiting groove 5 is replaced with a support with a roller structure 6, and the formwork, steel pipes and other materials are placed on the grille net 1, thereby assisting the transportation of the formwork, steel pipes and other materials and reducing labor intensity.
