Description

Technical Field

[0001] The utility model relates to the technical field of maintenance tools, in particular to a lifting maintenance platform. Background Art

[0002] During the mechanical maintenance of a hydro-turbine generator set, many devices need to be disassembled, lifted, placed, and transferred. For example, when the nozzle is being repaired in the runner chamber of an impulse turbine, a lifting point is usually welded or made above the equipment, and a hand winch is hung for lifting. The transfer of nozzle parts is often carried out by hand winches and manual labor for short-distance transfer, and manual lifting is used for long-distance transfer. The above-mentioned method is unreliable in terms of safety. When the nozzle parts are repaired, multiple hand winches are required to move and lift them. The nozzle parts may fall off due to unbalanced force, causing serious injuries to the operator. Second, the operation is inconvenient. Different lifting points are required for nozzle parts in different positions. Frequent switching of lifting points greatly reduces work efficiency. Therefore, a lifting and maintenance platform is proposed.

DETAILED DESCRIPTION

[0026] See also Figure 1 A lifting and maintenance platform includes a lift 10 and an auxiliary bracket 20. Casters 12 are respectively installed at the bottom corners of the lift 10. A plurality of mounting holes 13 are arranged on the top platform 11 of the lift 10. The auxiliary bracket 20 includes a support portion 21. At least one insertion rod 22 is arranged on the lower side of the support portion 21. The auxiliary bracket 20 is inserted into the mounting hole 13 through the insertion rod 22, so that the auxiliary bracket 20 is installed on the top platform 11. By installing the casters 12 at the bottom corners of the lift 10, it is convenient to move the parts. A plurality of mounting holes 13 are arranged on the top platform 11 of the lift 10. The auxiliary bracket 20 is inserted into the mounting hole 13 through the insertion rod 22, so that the auxiliary bracket 20 is installed on the top platform 11. By installing different auxiliary brackets 20, parts of different types and sizes can be positioned and supported. The structure is simple and easy to use.

[0027] exist Figure 1 In the embodiment, a plurality of mounting holes 13 are arranged in an array on the top platform 11 , so that the auxiliary bracket 20 can be flexibly installed at a desired position on the top platform 11 .

[0028] The casters 12 include two swivel casters and two fixed casters.

[0029] For further information, see Figure 2-5 The support portion 21 is a groove structure. Specifically, the groove structure is an arc groove, a trapezoidal groove, or a rectangular groove structure. Figure 2 , 3 In the embodiment, the support portion 21 is an arc-shaped groove structure. Figure 4 In the embodiment, the support portion 21 is a trapezoidal groove structure. Figure 5 In the embodiment, the support portion 21 is a rectangular groove structure. Different groove structures are designed to support and limit different components.

[0030] For further information, see Figure 2 The insertion rod 22 is provided with an external thread 24, the insertion rod 22 is inserted into the mounting hole 13, the external thread 24 extends downward out of the top platform 11 and is screwed and mounted with a nut 25, thereby improving the stability of the installation of the auxiliary bracket 20.

[0031] See also Figure 2 , 3 6. A support block 23 is provided at the lower side of the support portion 21, and the insertion rod 22 is fixedly installed at the lower side of the support block 23. The support block is provided to increase the height of the support portion 21. In actual use, due to the large area of ​​the top platform 11, when it is raised, the top platform 11 may interfere with the on-site environment, resulting in the inability of the components to be lifted into place. Therefore, the height of the support block can be increased according to actual needs.

[0032] See also Figure 6 , 7 In order to be able to adjust the left and right translation of the parts when installing the parts, the support block 23 includes a first part 231 and a second part 232. A slider 233 is provided on the lower side of the first part 231. The support part 21 is installed on the upper side of the first part 231. A slide groove 234 is provided on the upper side of the second part 232. The insertion rod 22 is fixedly installed on the lower side of the second part 232. The slider 233 is slidably installed in the slide groove 234. The slide groove 234 and the slider 233 can be adopted Figure 7 The dovetail structure in the embodiment may also adopt a structure of a "convex" shaped slide groove and a "convex" shaped slider.

[0033] Furthermore, the length of the slider 233 is less than the length of the slide slot 234, and baffles 235 are respectively installed at both ends of the second portion 232 located at the slide slot 234. The slider 233 is limited by the baffles 235 to prevent the slider from escaping from the slide slot.

[0034] Furthermore, the baffle 235 is screwed with a limit bolt 236, and the threaded end of the limit bolt 236 extends into the slide groove 234 and abuts against the slider 233. By adjusting the limit bolts 236 on both sides, the support part 21 can be translated stably. When in use, the limit bolt 236 on one side is loosened and the limit bolt 236 on the other side is tightened, so that the support part 21 can be translated, and after the translation, if the limit bolts 236 on both sides are tightened, the support part 21 will be limited.

[0035] The working principle or action process of the utility model is as follows:

[0036] When in use, two or more auxiliary brackets 20 are selected according to the parts to be installed, and the insertion rods 22 of the auxiliary brackets 20 are inserted into the mounting holes 13 at appropriate positions on the top platform 11, and the nuts 25 are screwed on.

[0037] Then the lift 10 is lowered, the parts are placed on the auxiliary bracket 20 for positioning, and the parts are transferred to the position where they need to be installed by the lift 10. Then the lift 10 is lifted up to lift the parts to the installation position. When installing the parts, the lift 10 adjusts the installation position of the parts forward and backward through the casters 12. Since the casters 12 cannot make the lift 10 translate left and right, the installation position of the parts is adjusted left and right by tightening the limit bolts 236 on both sides.
