DETAILED DESCRIPTION

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0022] like Figure 1 As shown, a water supply and drainage pipe positioning device provided in this embodiment includes a base 1, a mounting seat 2, a slip ring 3, a positioning member 4, a fixing plate 5, a locking member 6, a gear 7 and a motor 8.

[0023] The base 1 is used to fix the entire positioning device. The mounting seat 2 is fixed to the upper end of the base 1. The mounting seat 2 is a box-shaped structure with an open upper end, and has semicircular holes on two side walls in the X direction. The radius of the semicircular hole is greater than the radius of the profile cavity 34 of the slip ring 3.

[0024] like Figure 3 As shown, the mounting seat 2 is provided with arc-shaped slideways 21 on both side walls in the X direction. The arc-shaped slideways 21 are concave arc-shaped structures with L-shaped cross sections. The L-shaped arc-shaped slideways 21 are symmetrically arranged. The mounting seat 2 is provided with a lock 6 on one side in the Y direction, and a gear 7 is rotatably arranged on the other side in the Y direction. The gear shaft of the gear 7 is connected to the motor shaft of the motor 8. The gear 7 is driven to rotate by the motor 8. The motor is provided with a reducer.

[0025] like Figure 1 As shown, the slip ring 3 is rotatably arranged in the mounting seat 2, and the axial direction of the slip ring 3 is parallel to the X direction. Figure 1 , Figure 2 As shown, the slip ring 3 includes a first outer ring 31, a second outer ring 33 connected to one axial side of the first outer ring 31, and an inner ring 32 coaxially disposed inside the first outer ring 31 and the second outer ring 33. The inner cavity of the inner ring 32 forms a cavity 34 through which a drainage pipe passes.

[0026] The two ends of the inner ring 32 are connected to the first outer ring 31 and the second outer ring 33 through the side plates 35, so that the first outer ring 31, the second outer ring 33 and the inner ring 32 are connected as a whole through the side plates 35, and the sealing of the connection needs to be considered. A receiving space is formed between the side plates 35, the first outer ring 31, the second outer ring 33 and the inner ring 32, and the positioning member 4 is installed in the receiving space. Figure 2As shown, four positioning members 4 are evenly distributed on the circumference of the slip ring 3. The positioning member 4 can be optionally a waterproof servo electric cylinder or hydraulic cylinder capable of telescopic movement. The positioning member 4 can be arranged only in the first outer ring 31. The cylinder barrel of the positioning member 4 is connected to the inner wall of the first outer ring 31, and the telescopic rod of the positioning member 4 passes through the inner ring 32 and is fixed to the fixing plate 5. The inner ring 32 guides the telescopic movement of the positioning member 4. The fixing plate 5 is an arc-shaped plate. When it is necessary to position the pipeline, each positioning member 4 is retracted first, and then the pipeline is passed through the cavity 34, and then each positioning member 4 is started to extend at the same time, so that the fixing plate 5 on each positioning member 4 is attached to and clamped with the outer wall of the pipeline to achieve positioning. The solution of only setting the positioning member 4 in the first outer ring 31 is applied to the positioning of the pipeline that has been spliced.

[0027] In addition, the positioning member 4 can also be arranged inside the second outer ring 33, and the installation structure is the same as that in the first outer ring 31. In this way, the positioning member 4 in the first outer ring 31 positions one section of the water supply and drainage pipe, and the positioning member 4 in the second outer ring 33 positions the other section of the water supply and drainage pipe, which is applied to the positioning when the two pipes are butt-joined. The solution of respectively arranging the positioning members 4 in the first outer ring 31 and the second outer ring 33 is applied to the butt-joining and positioning of the pipes.

[0028] The positioning members 4 on the slip ring 3 can be started simultaneously to obtain a centering stroke, or can be started separately to achieve eccentric position adjustment (such as upward or downward adjustment).

[0029] The two ends of the slip ring 3 (i.e., the bottom outer surfaces of the first outer ring 31 and the second outer ring 33) are respectively adapted to the arc-shaped slideway 21 on the mounting seat 2. The first outer ring 31 is a gear ring, and a plurality of convex teeth 311 are arranged on its outer circle, and the convex teeth 311 mesh with the gear 7. The outer circle of the second outer ring 33 is a smooth surface, which is used to fit and lock with the locking plate 62 of the locking member 6.

[0030] When the motor 8 drives the gear 7 to rotate, the gear 7 drives the first outer ring 31 to rotate, thereby driving the slip ring 3 to rotate as a whole, and adjusting the position of the clamped water supply and drainage pipe.

[0031] like Figure 1 , Figure 3As shown, the locking member 6 includes a driving member 61 installed on the mounting seat 2 and extending radially along the slip ring 3, and a locking plate 62 connected to the end of the driving member 61. The driving member 61 can be a screw threadedly connected to the side wall of the mounting seat 2, or it can be an electric cylinder installed on the mounting seat 2. When the driving member 61 extends radially, the locking plate 62 abuts against the outer surface of the second outer ring 33 to lock the position of the slip ring 3 and the water supply and drainage pipe. At this time, the locking is also achieved by the self-locking of the motor 8. When the position of the water supply and drainage pipe needs to be rotated, the driving member 61 is retracted again, so that the locking plate 62 is disengaged from the second outer ring 33 and a gap is formed with the second outer ring 33 to achieve unlocking. A rubber sheet is provided on the outer surface of the locking plate 62, and the rubber sheet is in contact with the second outer ring 33 to increase friction.

[0032] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
