In the protruding part of the joint 5, the rotation direction of the thread on the female joint 1 is opposite to the rotation direction of the thread on the male joint 5. The side wall of the protruding part of the male joint 5 is provided with an annular groove, and the annular groove is located near the female joint 1. An end cover 2 is arranged in the groove, one end of the end cover 2 protrudes from the annular groove, the side wall of the extended part of the end cover 2 is provided with a through hole, the through hole is sleeved on the bolt 3, and the thread on the male joint 5 is located far away from the groove. At the annular groove, as shown in Figure 2, a guide belt 13 is provided between the socket part of the female joint 1 and the male joint 5 and between the annular groove and the end cover 2, and the socket part of the female joint 1 and the male joint 5 is provided A radial sealing ring 12 is arranged between them. As shown in Figure 3, a ratchet 6 is fixed on the side wall of the screw sleeve 4, and a wrench 7 and a pressure ring 8 are also sleeved on the side wall of the screw sleeve 4. The wrench 7 is located between the pressure ring 8 and the ratchet 6, the end of the wrench 7 away from the screw sleeve 4 is fixedly connected with a horizontal plate, the horizontal plate is perpendicular to the wrench 7, and a pawl 11 is movably connected to the side wall of the horizontal plate close to the screw sleeve 4, The pawl 11 is matched with the ratchet 6, and a crowbar 9 is fixed on the side wall of the horizontal plate away from the screw sleeve 4. As shown in Figure 4, a screw is fixed on the side wall of the horizontal plate close to the screw sleeve 4, and the screw is sleeved The ratchet 11 is connected, the screw is equipped with a nut 9, the ratchet 11 is located on the horizontal plate and the nut 9, the screw sleeve 4 and the ratchet wheel 6 are connected by splines, the screw sleeve 4 and the pressure ring 8 are connected by threads, and the screw sleeve 4 and wrench 7 are clearance fit.

The working principle of the double-speed telescopic high-pressure manifold connection device of the present invention is as follows: the male joint 5 and the female joint 1 are connected together by the end cover 2 and the bolt 3, and radial seals 12 and 12 are installed between the male joint 5 and the female joint 1. The guide belt 13 is used to guide the male and female joints when they move relative to each other, and to achieve high-pressure sealing at the same time. The screw sleeve 4 is connected with the male joint 5 and the female joint 1 through threads respectively. The male joint 5 and the female joint 1 are connected with the screw sleeve 4 in the opposite direction of the external thread. The ratchet 6, the spanner 7 and the pressure ring 8 are installed on the screw sleeve 4. The pawl 11 is mounted on the wrench 7 through the nut 9 , and the pawl 11 can freely rotate around the nut 9 .

Use the crowbar 10 to pull the wrench 7 to rotate around the screw sleeve 4, drive the pawl 11 installed on it to rotate together, drive the ratchet wheel 6 to rotate through the pawl 11, and then drive the screw through the spline between the ratchet wheel 6 and the screw sleeve 4. The sleeve 4 rotates; through the threaded connection between the threaded sleeve 4 and the male joint 5 and the female joint 1 , the rotational movement of the threaded sleeve 4 is converted into the axial movement of the male joint 5 . If the left side of the female connector 1 is fixed to the pipeline, the male connector 5 only moves axially and cannot be rotated. When the wrench 7 makes one revolution, the male joint 5 moves left or right by two pitches. To reverse, turn the pawl 11 180°.

The double-speed telescopic high-pressure manifold connection device of the present invention realizes the telescopic movement of the joint by adjusting the mutual positions between the male and female joints, thereby realizing the effective connection of the high-pressure manifold. The ratchet wheel 6 and the pawl 11 are engaged to form a screw transmission mechanism, and the lever principle of the crowbar 10 is used to generate a large torque with a small force to overcome the thread meshing and sealing resistance. At the same time, the double reverse threaded connection is used, the adjustment speed is doubled, and the overall length is shortened after all retractions.

The invention relates to a double-speed telescopic high-pressure manifold connection device, wherein the left end of the female joint is connected with the pipeline; then the male joint and the female joint are connected together through the end cover and the bolt, and the screw sleeve is installed on the male and female from the right end of the male joint, The screw sleeve is respectively connected with the male and female connectors through threads. Using the principle of crowbar 10 lever, with a small force, a large torque is generated to overcome the thread engagement and sealing resistance. That is, the wrench is pulled by the crowbar to rotate around the screw sleeve along the axis of the male and female joints, and the pawls installed on the wrench are driven to rotate together. The spline drives the threaded sleeve to rotate, and the threaded sleeve is connected with the male and female joints to convert the axial rotational movement of the threaded sleeve into the axial movement of the male joint. Through the telescopic movement of the joint, the mutual position between the male and female joints is adjusted to realize the effective docking of the high-pressure manifold.

At the same time, because the screw sleeve and the male and female joints have the opposite direction of rotation, the screw sleeve can rotate around the axial direction to drive the male and female joints to move toward or away from each other at the same time, so that the axial displacement adjustment speed of the male and female joints is doubled and all retracted. After the overall length is shortened.

A radial seal and a guide belt are installed between the male joint and the female joint; it guides the male and female joints when they move relative to each other, and at the same time achieves high-pressure sealing.

After adjusting the relative position between the male and female connectors, connect the right end of the female connector to the pipeline, and finally rotate the pressure ring to compress the wrench.

The assembling and disassembling process of a two-speed telescopic high-pressure manifold connection device of the present invention,

When assembling, first connect the left end of the female connector 1 with the left pipeline; then tighten the bolt 3, connect the male connector 5 and the female connector 1 through the end cover 2; install the pawl 11 on the wrench 7 through the nut 9 , the pawl 11 can rotate freely around the nut 9; install the ratchet 6, the wrench 7 and the pressure ring 8 on the nut 4, tighten the pressure ring 8, and press the wrench 7, so that the wrench 7 cannot rotate around the nut 4; Screw the screw sleeve 4 from the right end of the male joint 5 to the male joint 5 and the female joint 1 respectively; then loosen the pressure ring 8, so that the wrench 7 can rotate freely around the screw sleeve 4; use the crowbar 10 to pull the wrench 7 around the screw sleeve 4 rotates, drives the ratchet 11 installed on it to rotate together, drives the ratchet 6 to rotate through the ratchet 11, and then drives the threaded sleeve 4 to rotate through the spline between the ratchet 6 and the screw sleeve 4; 5 and the threaded connection between the female joint 1, can simultaneously drive the male joint 5 and the female joint 1 to move toward or away from each other, and adjust the relative position between the male joint 5 and the female joint 1; after the adjustment, tighten the pressure ring 8, Press the wrench 7 so that the wrench 7 cannot rotate around the screw sleeve 4; finally, connect the right end of the male joint 5 to the right pipeline.

When disassembling, first loosen the connection between the right end of the male joint 5 and the right pipeline, and then loosen the pressure ring 8, so that the wrench 7 can rotate freely around the screw sleeve 4; use the crowbar 10 to pull the wrench 7 to rotate around the screw sleeve 4, Pull out the nut 4 from the right end of the male joint 5, withdraw the pressure ring 8, the wrench, and the ratchet 6 from the nut, loosen the nut 9, and separate the pawl 11 from the wrench 7; The integral end cover 2 is loosened from the male joint 5, and then the male joint 5 is separated from the female joint 1; finally, the connection between the female joint 1 and the left pipeline is loosened.
