Description

Ground pump pipe adapter

Technical Field

The invention relates to a pipeline splicing member, in particular to a ground pump pipe adapter.

Background

The pouring or pouring of concrete all needs the ground pump to carry, usually uses pipe strap, waterstop and bolt to splice between the present ground pump pipe. Because the pipe strap belongs to the rigid piece, need accurate location just can install, but in pump truck and cloth machine department, pump truck and cloth machine area are great be difficult to accurate location place, and the ground pump pipe is also in fixed state, consequently very difficult one step concatenation is put in place, once the concatenation is not put in place, just needs the aversion to splice again, and is time consuming and labor consuming.

Disclosure of Invention

The invention aims to provide a ground pump pipe adapter which can adjust axial offset and expansion and contraction and can splice without shifting a ground pump pipe.

The technical scheme adopted by the invention is as follows:

the utility model provides a ground pump pipe adapter, including movable disk and fixed disk, the center of movable disk is equipped with the aperture, the distribution has the through hole all around, the center of fixed disk is equipped with the macropore, the distribution has the screw hole that corresponds with the through hole all around, the outer fringe card has put the ring that seals up all screw holes and surround, the one end card of screw is on the through hole, thereby the cooperation passes corresponding screw hole and by the nut screw up after passing through the through hole in other end clearance makes movable disk and fixed disk axial connection and compress tightly the ring that seals up, the movable disk can utilize the clearance perpendicular to axial skew of screw and through hole and during the skew aperture in the coverage of macropore all the time, the one end of an outer takeover is the pipe strap, the other end is fixed on the movable disk and with the sealed surrounding of aperture, the one end of another outer takeover is the pipe strap, the other end is fixed on the fixed disk and with the sealed surrounding of macropore, external flexible pipe has on the takeover of movable disk and/or fixed disk.

Further, the telescopic pipe comprises an outer pipe and an inner pipe which are sleeved together in a sliding fit manner and are not separated, and pipe clamps are arranged at the ends, away from each other, of the outer pipe and the inner pipe.

Further, a spline groove is formed in the outer tube, a spline matched with the spline groove is formed in one end, away from the pipe clamp, of the inner tube, and limiting rings used for preventing the spline from falling out of the spline groove are arranged at two ends of the outer tube.

Further, the pipe clamp is connected to one end of the outer pipe far away from the inner pipe through a conical pipe.

Further, the outer tube comprises a tube clamp and a conical tube which are axially connected into a whole.

The beneficial effects of the invention are as follows:

when positioning errors exist among the local pump pipes, the axial offset can be adjusted through the movable disc, the axial expansion amount can be adjusted through the expansion pipe, and the splicing can be performed without shifting the local pump pipes.

Detailed Description

The invention is further described below with reference to the drawings and examples.

As shown in fig. 1 to 3, a ground pump pipe adapter comprises a movable disk 3 and a fixed disk 2, wherein a small hole 31 is arranged in the center of the movable disk 3, through holes 32 are distributed around the movable disk 3, a large hole 21 is arranged in the center of the fixed disk 2, threaded holes 22 corresponding to the through holes 32 are distributed around the fixed disk 2, a water stop ring 5 surrounding all the threaded holes 22 is clamped at the outer edge, one end of a screw 6 is clamped on the through holes 32, the other end of the screw is matched with the corresponding threaded holes 22 after passing through the through holes 32 and is screwed by a nut 7, so that the movable disk 3 and the fixed disk 2 are axially connected and tightly press the water stop ring 5, the movable disk 3 can be axially offset by utilizing the clearance of the screw 6 and the through holes 32 in a perpendicular to the axial direction, and the projection of the small hole 31 in the axial direction is always within the coverage range of the large hole 21, one end of one outer connecting pipe 1 is a pipe clamp 11, the other end of the other outer connecting pipe 1 is fixedly arranged on the movable disk 3, the other end of the other outer connecting pipe 1 is fixedly arranged on the fixed disk 2, the other end of the outer connecting pipe 1 is tightly surrounded by the small hole 21, the telescopic pipe 1 is externally connected by the large hole 1, and the outer connecting pipe 1 is axially connected by the large pipe clamp 11, and the whole pipe 11 is in a conical pipe 12. When there is a positioning error between the local pump pipes, the axial offset can be adjusted through the movable disk 3, the axial expansion can be adjusted through the telescopic pipe 4, the splicing can be carried out without shifting the local pump pipes, the telescopic pipe 4 can be independently externally connected with the movable disk 3 or the fixed disk 2, and can also be simultaneously externally connected with the movable disk 3 and the fixed disk 2.
