Description

Technical Field

[0001] The utility model relates to a sandblaster for the anti-corrosion inner wall of a petroleum pipeline, belonging to the technical field of sandblasters. Background Art

[0002] Pipeline interior sandblasters are specialized tools for cleaning the interior of metal pipes. They are primarily used for sandblasting the interior of small pipes. Because pipes are narrow, standard forward-jet single- and dual-jet sandblasters cannot change direction within the pipe, preventing them from sandblasting the interior. Traditional pipeline anti-corrosion sandblasters utilize a frame with a wheeled mechanism for sandblasting. These devices utilize a fixed-position mounting design that prevents quick disassembly and exhibits poor stability during operation. Utility Model Content

The docking plug-in block and the central sleeve are welded and installed in a cross shape, and the docking plug-in block is inserted into the inner groove of the docking frame and docked.

[0006] Preferably, the vertical travel shock-absorbing bracket consists of a universal roller, an adjustable shock-absorbing spring connecting rod and a spring stabilizing bracket. The universal roller is threadedly screwed on the top of the adjustable shock-absorbing spring connecting rod, and the lower end of the adjustable shock-absorbing spring connecting rod is installed in combination with the spring stabilizing bracket.

[0007] Preferably, the spring stabilizing bracket is composed of a stabilizing sleeve, a supporting link, a supporting spring group and a positioning mounting block, and the stabilizing sleeve is mounted in linkage with the positioning mounting block through the supporting link and the supporting spring group.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] The docking bracket consists of a docking frame, a docking plug and a center sleeve. The docking plug and the center sleeve are welded in a cross shape. The docking plug is inserted into the inner groove of the docking frame, which is convenient for quick disassembly. The horizontal and vertical travel cushioning bracket can be quickly disassembled by screwing.

[0010] The vertical travel shock-absorbing bracket consists of a universal roller, an adjustable shock-absorbing spring link and a spring stabilizing bracket. The spring stabilizing bracket consists of a stabilizing sleeve, a supporting link, a supporting spring group and a positioning mounting block. The adjustable shock-absorbing spring link is height-adjustable with a vertical shock-absorbing spring.
