Description

A quick connection anti-detachment device for mud delivery pipeline

technical field

The utility model belongs to the field of pipeline connection devices, in particular to a quick-connection anti-detachment device for a mud delivery pipeline.

Background technique

The current pipeline connection joint is mainly composed of a male joint and a female joint. After the male joint and the female joint are respectively connected to a pipeline, the male joint and the female joint are correspondingly connected. When connecting movable pipelines, the pipeline connection joints are also required. In the process of connecting the mud pipeline, the pipeline needs to be moved during the mud transportation process. When moving along the axial direction of the pipeline, the pipeline connection joint will be in contact with the end surface of the pipeline. 1. Collision between sundries on the water surface is prone to fracture and damage of the pipeline connection joints. After the pipeline connection joints are broken, the pipeline will be cut off, the control pressure in the mud pipeline will decrease, and the equipment will be seriously damaged; the process of pumping sludge During the process, the internal pressure of the mud pipeline increased sharply, and the stress of the pipe connection joints also increased accordingly. The connected mud pipeline was easy to fall off or burst, causing major safety accidents.

Utility model content

The purpose of the utility model is to provide a quick connection anti-detachment device for the mud delivery pipeline, which makes the pipeline connection more convenient, safe and reliable, improves the efficiency of sludge delivery, and avoids problems such as pipe detachment or pipe burst in the mud delivery pipeline.

The purpose of this utility model is achieved in this way: a quick-connect anti-off device for a mud delivery pipeline, comprising a first connector and a second connector, and the first connector and the second connector are connected through a locking sleeve , the sealing connection between the first connecting head and the locking sleeve, the inner wall of the locking sleeve is provided with an inner step, the second connecting head is correspondingly inserted into the inside of the locking sleeve, and the inner shaft of the locking sleeve A compression spring is arranged in the direction, one end of the compression spring is elastically resisted on the annular end surface of the second connector, and the other end of the compression spring is elastically resisted on the annular inner step, and the outer wall of the second connector is provided with an annular locking ring along the circumferential direction. The outer wall of the second connecting head is axially provided with an unlocking groove connected with the locking groove, and the end of the locking sleeve close to the second connecting head is provided with a mounting hole corresponding to the locking groove, and the mounting hole is set There are limit pins that can be inserted into the locking grooves.

When the utility model is locked, first connect the two mud pipes to be connected to the first connector and the second connector respectively, then insert the other end of the first connector into the locking sleeve, and the second connector The other end of the connector is inserted into the locking sleeve, the end face of the second connector squeezes the compression spring until the mounting hole is facing the locking groove, the limit pin is installed in the mounting hole, and the end of the limit pin snaps into the locking In the groove, turn the second connector so that the limit pin is far away from the unlocking groove, and the second connector is in the locked position to complete the connection of two mud pipelines; when unlocking, turn the second connector so that the limit pin is close to the unlocking groove, Push the second connector axially to move the limit pin out of the locking groove to complete the unlocking. Compared with the prior art, the utility model has the beneficial effects as follows: firstly, two mud delivery pipes can be quickly connected through the limit pin, and the connection is more convenient; second, the pressure spring allows the mud delivery pipeline to have an axial movement gap , the pressure spring drives the mud delivery pipeline to reset, and then the locking sleeve and the second connector are locked again, which can effectively prevent the connection head from disconnecting when the mud delivery pipeline moves substantially, and the connection of the mud delivery pipeline is safer and more reliable. The efficiency of sludge transportation is improved, and problems such as pipe detachment or pipe burst in the mud transportation pipeline are avoided.

In order to improve the locking effect and avoid loosening between the locking sleeve and the second connector, at least two mounting holes are symmetrically arranged on the locking sleeve along the axis.

As a preference of the present invention, the first connector is a male connector, and the second connector is a female connector.

In order to realize the sealed connection between the first connecting head and the locking sleeve more conveniently, the first connecting head is inserted into the locking sleeve, and the outer wall of the first connecting head is in interference fit with the inner wall of the locking sleeve.
