Description

Technical Field

[0001] The utility model belongs to the technical field of mine operation, and relates to a flange butt joint angle auxiliary device used for underground mine operation. Background Art

[0002] Due to the characteristics of the underground production environment and operation methods of metal mines, the Fengshui pipelines in the mining area are often damaged or broken and cannot be used normally. In order to ensure normal production order, the damaged Fengshui pipelines need to be replaced. Therefore, the maintenance personnel have a heavy workload of welding the Fengshui pipeline flanges.

[0003] The traditional method of welding Feng Shui pipe flanges requires maintenance personnel to use a ruler to align the angle to ensure that the flange and the pipe are 90°, and in this process, it is necessary to align the angle multiple times through spot welding, knocking and other methods, resulting in low efficiency in welding Feng Shui pipe flanges.

[0004] Therefore, it is necessary to design an auxiliary device for quickly finding the docking angle of the Feng Shui pipeline flange in the mine to solve the above problems, achieve the purpose of directly and quickly finding the docking angle of the Feng Shui pipeline flange, and complete the docking work of the Feng Shui pipeline flange in the mine. Utility Model Content

[0005] The purpose of the utility model is to provide a flange docking angle auxiliary device for underground mine operations in view of the problems existing in the prior art, thereby solving the problem that the existing Fengshui pipeline cannot be quickly aligned when repairing it in underground mine operations.

[0006] To this end, the utility model adopts the following technical solutions:

[0007] A flange docking angle auxiliary device for underground mining operations comprises a bracket, the cross section of the bracket is U-shaped, and flange support plates are arranged at both ends of the bracket. The flange support plates are circular and have a U-shaped notch. The width of the notch is equal to the inner diameter of the bracket. The bottom of the bracket is provided with a plurality of symmetrically arranged outer sleeves, and an inner sleeve is inserted into the interior of the outer sleeve, and the two are movably connected by a screw.

[0008] Furthermore, the length of the flange support plate gap is greater than the length of the bracket.

[0009] Furthermore, the bracket is made of channel steel.

[0010] The beneficial effects of the utility model are:

[0013] In the figure, 1-flange support plate, 2-bracket, 3-outer sleeve, 4-inner sleeve, 5-screw. DETAILED DESCRIPTION

[0014] The technical solution of the utility model is described below in conjunction with the accompanying drawings and implementation methods.

[0015] like Figure 1 As shown, a flange butt angle auxiliary device for underground mining operations comprises a bracket (2). Specifically, the bracket (2) is made of channel steel; the cross section of the bracket (2) is U-shaped, and flange support plates (1) are provided at both ends; the flange support plate (1) is circular and is provided with a U-shaped notch, the width of the notch is equal to the inner diameter of the bracket (2), and the length of the notch is greater than the length of the bracket (2).

[0016] Two symmetrically arranged outer sleeves (3) are provided at the bottom of the bracket (2), an inner sleeve (4) is inserted into the inner part of the outer sleeve (3), and the two are movably connected via a screw (5).

[0017] Specifically, the flange support plate (1) is composed of a disc with an opening height of 6 cm, a width of 5 cm and a diameter of φ15 cm; the bracket (2) is composed of an I-shaped channel steel with a width of 6 cm, a height of 4 cm and a length of 40 cm, and the flange support plates (1) are welded at both ends of the bracket (2) for fixing the Feng Shui pipeline; the diameter of the inner sleeve (4) is φ1.5 cm and the length is 8 cm, the diameter of the outer sleeve (3) is φ1.8 cm and the length is 12 cm, and the diameter of the screw (5) is φ0.5 cm and the length is 2 cm.

[0018] During use, the utility model uses two brackets (2) to fix a section of the Feng Shui pipeline, and then uses two brackets (2) to fix another section of the Feng Shui pipeline, inserts the inner sleeve (4) into the outer sleeve (3), and uses a screw rod (5) to control the distance, thereby adjusting the height of the Feng Shui pipeline, so as to quickly align the flange connection angles of the two sections of the Feng Shui pipeline, improve the quick alignment efficiency of the Feng Shui pipe in the mine, and better complete the connection work of the Feng Shui pipe in the mine.
