Description

Technical Field

[0001] The utility model relates to the technical field of wear-resistant pipeline production, in particular to cross-section polishing and packaging equipment for wear-resistant pipeline production. Background Art

[0002] Wear-resistant pipes are composite pipes used in engineering areas with severe wear and tear. They have a wear-resistant layer inside. They are composite pipes that save energy and reduce emissions, and are wear-resistant and anti-corrosive. Wear-resistant pipes need to be cut during production. After cutting, a cross-section is formed. In order to reduce the sharpness of the cross-section, the cross-section needs to be polished again. However, during polishing, the cross-section temperature is high and there is enough oxygen outside, which can easily cause the polished cross-section to oxidize. In order to avoid cross-section oxidation, a cross-section polishing and packaging equipment for wear-resistant pipe production is designed to facilitate cross-section polishing in an air-sealed state, avoid oxidation of the cross-section after polishing, and ensure the cleanliness of the cross-section polishing.

A limiting ring is fixedly connected to the inner wall of the fixed sleeve and is rotatably and slidingly matched with the connecting ring sleeve. It also includes a rotating drive component that drives the connecting ring sleeve to rotate.

[0008] Preferably, the rotary drive assembly includes a gear rotatably connected to the inside of the fixed sleeve, a gear ring meshing with the gear is fixedly installed on the side of the connecting ring sleeve away from the polishing disk, and the fixed sleeve also includes a drive motor for driving the gear to rotate.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides a cross-section polishing and packaging device for wear-resistant pipeline production, which has the following beneficial effects:

[0014] The cross-section polishing and packaging equipment for the production of wear-resistant pipes can seal the inner and outer sides of the wear-resistant pipe respectively through the inner wall packaging mechanism and the outer wall packaging mechanism when the fixed sleeve is put on the end of the wear-resistant pipe, so that a sealed space is formed between the end of the wear-resistant pipe and the fixed sleeve. When the cross-section polishing mechanism is pressed against the cross-section of the wear-resistant pipe, the distance between the front sealing plate and the rear sealing plate can be shortened by adjusting the inner sealing adjustment component, so that the inner rubber ball cover expands to the surroundings, so that the inner wall of the wear-resistant pipe is tightly sealed to ensure the sealing performance. The cross-section polishing mechanism can be started to polish the cross-section of the wear-resistant pipe in the sealed space. At the initial stage of polishing, the temperature at the polishing surface increases, thereby reacting with the oxygen in the sealed space. As the polishing proceeds, the oxygen is consumed while the oxidized surface is polished, so that the later polishing of the wear-resistant pipe can be performed without oxygen. After cooling, the equipment can be removed from the end of the wear-resistant pipe. The cross-section polishing and packaging equipment for the production of wear-resistant pipes can be performed in an air-sealed state to avoid oxidation of the cross-section after polishing, and ensure the cleanliness of the cross-section polishing.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example:

[0021] See also Figure 1-3 A cross-section polishing and packaging device for the production of wear-resistant pipes comprises a wear-resistant pipe 1 and a fixed sleeve 2 which can be sleeved on the end of the wear-resistant pipe 1, an inner front side of the fixed sleeve 2 is provided with an inner wall packaging mechanism and an outer wall packaging mechanism which are compatible with the wear-resistant pipe 1, an inner rear side of the fixed sleeve 2 is provided with a cross-section polishing mechanism, the inner wall packaging mechanism comprises an inner rubber ball cover 4, the outer wall packaging mechanism comprises an outer rubber ring cover 3, both sides of the inner rubber ball cover 4 are sealed and fixedly connected with a front sealing plate 5 and a rear sealing plate 6, the outer rubber ring cover 3 is sealed and fixedly connected with the fixed sleeve 2, the rear sealing plate 6 is fixedly connected with the inner wall of the fixed sleeve 2, and also comprises an inner sealing adjustment component which is provided with the spacing between the front sealing plate 5 and the rear sealing plate 6.

[0022] Specifically, the cross-section polishing mechanism includes a polishing disk 13, and a connecting ring sleeve 11 is fixedly connected to the side of the polishing disk 13 away from the inner wall packaging mechanism and the outer wall packaging mechanism. A limit ring 10 is fixedly connected to the inner wall of the fixed sleeve 2 and is rotatably and slidably matched with the connecting ring sleeve 11. It also includes a rotating drive component for driving the connecting ring sleeve 11 to rotate. The rotating drive component can easily drive the connecting ring sleeve 11 and the polishing disk 13 to rotate, so that the polishing disk 13 can polish the cross-section of the wear-resistant pipe 1.

[0023] Specifically, the rotary drive assembly includes a gear 15 rotatably connected to the inside of the fixed sleeve 2, a gear ring 14 meshing with the gear 15 is fixedly installed on the side of the connecting ring sleeve 11 away from the polishing disk 13, and the fixed sleeve 2 also includes a drive motor 16 for driving the gear 15 to rotate. Furthermore, the drive motor 16 is fixedly installed on the fixed sleeve 2, and the drive motor 16 is started to rotate the output shaft of the drive motor 16, so as to drive the gear 15 to rotate. Through the meshing of the gear 15 and the gear ring 14, the connecting ring sleeve 11 and the polishing disk 13 are driven to rotate, so that the cross section of the wear-resistant pipe 1 can be polished by the rotating polishing disk 13.

[0024] Specifically, the inner seal adjustment component includes a screw sleeve 7 and a screw 8 threadedly connected to the screw sleeve 7. The rear sealing plate 6 is fixedly connected to the fixed sleeve 2 through the screw sleeve 7. One end of the screw rod 8 is rotatably connected to the front sealing plate 5. The other end of the screw 8 is fixedly installed with a rotating disk 9. The polishing disk 13 rotates in cooperation with the screw sleeve 7. By rotating the rotating disk 9, the screw rod 8 can be driven to rotate in the screw sleeve 7, so that the front sealing plate 5 can be moved closer to the rear sealing plate 6 or away from the rear sealing plate 6.

[0025] Specifically, a handle 17 is fixedly installed on the outside of the fixing sleeve 2, and a through hole is opened and closed on the handle 17 for the screw 8 to pass through. The handle 17 is used to facilitate the fixing sleeve 2 to be stabilized during cross-section polishing, and the through hole is provided to facilitate the passage of the screw 8.

[0026] Specifically, a limiting ring groove is provided on the limiting ring 10, and a retaining ring 12 fixedly connected to the connecting ring sleeve 11 is slidably fitted in the limiting ring groove. Through the cooperation between the limiting ring groove and the retaining ring 12, the connecting ring sleeve 11 can be limited conveniently, and the connecting ring sleeve 11 can be rotated relative to the limiting ring 10, thereby improving the rotation stability of the polishing disk 13.

[0027] When in use, the fixed sleeve 2 is sleeved on the end of the wear-resistant pipe 1, the inner wall packaging mechanism is inserted into the inner wall of the wear-resistant pipe 1, and the outer wall packaging mechanism is slid on the outer wall of the wear-resistant pipe 1 until the cross-section polishing mechanism is against the cross-section of the wear-resistant pipe 1, and then the distance between the front sealing plate 5 and the rear sealing plate 6 is shortened by the inner sealing adjustment component, so that the inner rubber ball cover 4 expands outward to be close to the inner wall of the wear-resistant pipe 1, so that a sealed space is formed between the end of the wear-resistant pipe 1 and the fixed sleeve 2, and then the cross-section polishing mechanism is started to polish the inner wall of the wear-resistant pipe 1. In the early stage of polishing, since there is oxygen in the upwind space, an oxidized surface will be formed on the polishing surface during the initial polishing. However, as the polishing proceeds, the oxidized surface will be polished down, and the oxygen in the sealed space will be consumed, and then the polishing will continue. The later polishing is anaerobic polishing. After the polishing is completed, the equipment can be pulled out from the end of the wear-resistant pipe 1 after the polishing surface has cooled.
