Description

Technical Field

[0001] The invention relates to the field of engineering machinery, in particular to a single steel wheel vibratory roller. Background Art

[0002] During the compaction process of a single-drum vibratory roller, debris often adheres to the surface of the vibratory wheel, affecting the compaction quality. Therefore, a single-drum vibratory roller needs to be equipped with a mud scraper. The vibratory wheel of a single-drum vibratory roller is divided into a smooth wheel and a convex wheel (ram horn wheel). Figure 1 and Figure 2 As shown, the smooth wheel is equipped with a scraper blade 4, and the lug wheel is equipped with a scraper tooth 6. The number of scraper tooth bases of the two is different. The number of scraper tooth bases 3a of the smooth wheel scraper blade 4 is 8, 4 at the front and rear, while the number of scraper tooth bases of the lug wheel is 18, 9 at the front and rear. Most single-steel-wheel vibratory rollers are produced and stocked according to the smooth wheel configuration. When receiving an order for the lug wheel configuration, the factory will add a lug shell 5 to the smooth wheel 1 of the roller, and increase the number of scraper tooth bases on the front beam 2 and the rear beam for installing the scraper tooth 6. During the modification process, the vibrating wheel needs to be removed, and lines need to be drawn on the bottom of the front and rear beams. The 10 scraper tooth bases need to be welded one by one at the specified position, and the position and size of the scraper tooth base cannot be guaranteed, which is time-consuming and labor-intensive. Summary of the invention

[0003] Purpose of the invention: To provide an installation device and method for a modified skiving base for a road roller. In the process of changing a smooth wheel to a cam wheel, the smooth wheel is not removed. The skiving base can be directly welded to the front beam or the rear beam through tooling to form a cam wheel, and its position and size can be guaranteed, saving time and labor.

[0004] Technical solution:

[0005] A mounting device for a modified skiving base of a road roller comprises a tooling plate, on which M groups of mounting holes and N welding holes are arranged; M and N are both positive integers, and M>N;

[0006] Among them, the MN group of mounting holes corresponds to the original MN scraper base positions on the smooth wheel, and the positions of the N group of mounting holes correspond to the positions of the N scraper tooth bases that are more than the smooth wheel before the modification.

[0016] The third step: Orient the other ends of the N scraping tooth bases on the tooling plate towards the smooth wheel, and connect the remaining M - N groups of installation holes on the tooling plate to the outer ends of the original M - N mud scraping bases on the smooth wheel to fix the tooling plate.

[0017] The fourth step: Preliminarily fix the other ends of the N scraping tooth bases to be installed to the front beam or the rear beam respectively through the N welding holes on the tooling plate.

[0018] The fifth step: Remove the tooling plate.

[0019] The sixth step: Re - fix the N scraping tooth bases to be installed.

[0020] The seventh step: Install scraping teeth on all the scraping tooth bases.

[0021] Beneficial effects:

[0028] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and cannot be used to limit the protection scope of the present invention.

[0029] In this embodiment, a smooth wheel with 4 scraping tooth bases and a bump wheel with 5 scraping tooth bases are taken as examples for illustration.

[0030] When the vibrating wheel is a smooth wheel, its mud scraping device is as shown in Figure 1 ;

[0031] When the vibrating wheel is a bump wheel, its mud scraping device is a scraping tooth, as shown in Figure 2 .

[0032] As shown in Figure 3 , the installation device of the present invention includes a tooling plate 7. Nine groups of mounting holes 71 and 72 are provided on the tooling plate 7. One end of the scraping tooth base can be connected and fixed to the tooling plate 7 through the mounting hole 71. Among them, 4 groups of mounting holes 71 correspond one by one to the positions of the original 4 mud scraping bases 3a on the smooth wheel 1, and the positions of the other 5 groups of mounting holes 72 correspond one by one to the positions of the 5 mud scraping bases 3b (i.e., the 5 mud scraping bases 3b that need to be added to the smooth wheel 1 during modification) on the bump wheel on the front beam 2 or the rear beam, which are used for supporting and positioning the mud scraping base 3b to be installed. A welding hole 73 is provided beside each of the 5 groups of mounting holes 72. The welding gun can pass through the tooling plate 7 through the welding hole 73 and extend into the other end facing the inside of the mud scraping base 3b to be installed, and the other end of the mud scraping base 3b is welded to the front beam or the rear beam.

[0033] The shapes of the mounting holes 71 and 72 are round holes or oblong holes.

[0035] When the shape of the welding hole 73 is a rectangular hole, the length ≥ 100 mm and the width ≥ 50 mm.

[0036] The tooling plate is made of steel plate.

[0037] The thickness of the tooling plate ≥ 2 mm.

[0038] When the smooth wheel is modified into a bump wheel, as shown in Figure 4 , the installation method is as follows:

[0039] Step 1: Remove the mud scraping plate 3 configured on the optical wheel 1 and install a bump housing 5 on the optical wheel 1;

[0040] Step 2: Assemble one end of the five scraper tooth bases 3b to be installed to the positions of five groups of mounting holes 72 corresponding to the welding holes 73 on the tooling plate 7 through bolts;

[0041] Step 3: Install the tooling plate 7 with five scraper tooth bases 3b on the front beam 2 or the rear beam, and make the other ends of the five scraper tooth bases 3b face the direction of the optical wheel, that is, connect the tooling plate 7 to the outward-facing ends of the original four mud scraping bases 3a on the optical wheel 1 by passing bolts through the remaining four groups of mounting holes 71 on the tooling plate 7, so as to fix the tooling plate 7;

[0042] Step 4: Use a welding torch to spot-weld the other ends of the five scraper tooth bases 3b to the front beam 2 or the rear beam in sequence through the welding holes 73 on the tooling plate 7 to preliminarily weld and fix the five scraper tooth bases 3b;

[0043] Step 5: Remove the tooling plate 7 to separate the tooling plate 7 from the five scraper tooth bases 3b and the original four mud scraping bases 3a;

[0044] Step 6: Weld the five scraper tooth bases 3b according to the drawing to achieve final welding and fixing;

[0045] Step 7: Install the scraper teeth 6 on the scraper tooth bases 3a and 3b in sequence.

[0046] The above is only the preferred embodiment of the invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
