Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of underground pipeline rotating device. BACKGROUND

[0002] Due to coal mine explosion-proof requirements, when installing pipeline in underground roadway, welding method is often not adopted, and threaded connection or flange connection is usually used. When threaded connection is used, the pipeline with threaded pipe at both ends needs to be rotated, and the prior art lacks corresponding pipeline rotating device, so manual rotation is the only way, which is labor-intensive. SUMMARY

[0003] The utility model solves the technical problem of filling the above-mentioned gap in the prior art, and provides an underground pipeline rotating device.

[0004] To solve the above technical problems, the underground pipeline rotating device comprises a base 1, an annular gear ring 2, a gear 3, a driving motor 4 and a wedge block set. The base 1 is provided with two pairs of adjacent support columns 5, and the inner side of the top of each adjacent support column 5 is provided with a roller 6. The annular gear ring 2 is clamped between the adjacent support columns 5 on both sides, and a ring-shaped slide 7 is formed on the surface of the annular gear ring 2. The roller 6 extends into the ring-shaped slide 7. The outer circumference of the annular gear ring 2 is uniformly provided with teeth. The gear 3 is engaged with the teeth on the annular gear ring 2, and the gear 3 is driven by the driving motor 4. The wedge block set comprises at least four wedge blocks 8, each of which is thick at one end and thin at the other end.

[0005] In use, the annular gear ring 2 is sleeved on the pipeline to be rotated, the wedge block 8 is inserted between the pipeline to be rotated and the annular gear ring 2, the axis of the pipeline to be rotated coincides with the axis of the annular gear ring 2, and the pipeline to be rotated is clamped. Then, the driving motor is started according to the needs, and the pipeline with threaded pipe at both ends can be rotated, which is very labor-saving.

[0006] As an optimization, universal casters 9 are installed below the base 1. This design facilitates movement.

[0007] As an optimization, the upper surface of the base 1 is provided with two opposite bearing seats 10, each bearing seat 10 is provided with a bearing, and the center of the gear 3 is provided with a gear shaft 11. The gear shaft 11 is inserted into the bearings of the two bearing seats 10 and is coaxially fixed with the output shaft of the driving motor 4. This design is simple in structure and firm in installation.

[0008] As an optimization, the inner side of each wedge block 8 is an inner concave arc surface, and a plurality of rubber protrusions 12 are embedded in the inner side of each wedge block 8. This design facilitates the clamping of the wedge block 8 on the pipeline to be rotated.

[0009] The underground pipeline rotating device of the utility model is simple in structure, labor-saving and convenient, and is suitable for rotating and installing the pipeline with threaded pipe at both ends. BRIEF DESCRIPTION OF DRAWINGS
