DETAILED DESCRIPTION

[0045] The present invention is further described in detail below through embodiments. The embodiments are only used to illustrate the present invention and do not limit the scope of the present invention.

[0046] A tailwater elbow weld gap adjustment device, comprising:

[0047] The substrate 100 is a square plate-like structure, and the number of substrates is two and they are symmetrically arranged; the substrate 100 is fixed on the steel plate 120, and a weld 110 is formed between two adjacent steel plates 120, and the substrate 100 is located on both sides of the weld 110; during use, the substrate 100 is pre-welded and fixed on the steel plate 120, and acts on the steel plate 120 through the substrate 100, thereby adjusting the size of the weld 110.

[0048] The adjusting seat 200 is fixed on the substrate 100. The number of adjusting seats 200 is two and they are symmetrically arranged. The adjusting seat 200 is detachably connected to the substrate 100; the adjusting seat 200 is fixedly connected to the steel plate 120 through the substrate 100. Specifically, the adjusting seat 200 is detachably connected to the substrate 100 by means of bolts. The adjusting seat 200 and the substrate 100 are selected to be a split detachable structure, which is beneficial for the adjusting seat 200 and the substrate 100 to be disassembled and installed more flexibly.

[0049] The connecting part 300 is detachably connected to the main body of the adjusting seat 200; the connecting part 300 is equivalent to a "force application point". According to the use requirements, the position of the connecting part 300 relative to the adjusting seat 200 can be preset, and at the same time, the number of the connecting parts 300 can be preset, so that the stretching effect on the adjusting seat 200 and the substrate 100 can be changed more flexibly.

[0050] The stretcher 400 is detachably connected to the connecting part 300. The stretcher 400 is connected to the adjusting seat 200 through the connecting part 300, and the length of the stretcher 400 is adjustable; the connecting part 300 serves as a "carrier" for connecting the stretcher 400 with the adjusting seat 200 and the substrate 100. The distance between adjacent substrates 100 can be adjusted through the stretcher 400, thereby adjusting the distance between adjacent steel plates 120.

[0051] Through the detachable connection between the connecting part 300 and the adjusting seat 200, according to the stretching requirement, the number of the connecting parts 300 can be adjusted, and then the connecting part 300 is fixed to the stretcher 400, and the distance between adjacent steel plates 120 is adjusted through the stretcher 400.

[0052] For key reference Figure 3 , installation grooves 130 are opened on both sides of the substrate 100. The cross-section of the installation groove 130 is in a "U" shape, and the installation groove 130 extends from one end of the substrate 100 to the other end; the installation groove 130 can be used as a space for installing nuts in the later stage.

The cross-section of the slot 140 is in a "U" shape, and the slot 140 extends from one end of the substrate 100 to the other end. The slot 140 serves as a "limit slot" for the installation of the adjustment base 200, facilitating the installation of the adjustment base 200 and the substrate 100 in the early stage and increasing the stability of the installation of the adjustment base 200 and the substrate 100.

[0054] On both sides of the upper part of the substrate 100, through holes for bolts 150 are opened; the through holes for bolts 150 are used for the later fixation (bolted fixation) of the adjustment base 200 and the substrate 100.

Through holes for bolts 221 are opened through the wing plates 220. The number of the through holes for bolts 221 is several and evenly distributed on the wing plates 220. When the vertical plate 210 is inserted into the slot 140, the wing plates 220 are lapped with the side surface of the substrate 100, then the through holes for bolts 150 and the through holes for bolts 221 are correspondingly arranged, and then the vertical plate 210 and the substrate 100 are fixed by bolting.

[0059] A threaded hole 231 is arranged between adjacent slots 230, and the threaded hole 231 is opened on the vertical plate 210; the number of the threaded holes 231 is multiple and evenly distributed on the vertical plate 210. During installation, one side of the main body of the connecting part 300 can slide on the vertical plate 210 through the slot 230, so as to control the position of the connecting part 300 relative to the vertical plate 210, and then the connecting part 300 and the vertical plate 210 are fixed by screwing.
