Description

Technical Field

[0001] The present invention relates to the field of pipeline installation sealing, and particularly to a rapid installation and locking device for the toroidal surface of a pipeline. Background Art

[0002] Pipeline sealing or installation equipment is often used in the daily equipment maintenance of pipelines. Due to the wide application of pressure pipelines and the many types of pressure pipelines, it is sometimes necessary to install or seal various temporary maintenance or inspection equipment in the pipelines. Usually, inside pipelines with harsh environments, there are high requirements for installation time and installation convenience. However, the structures of existing pipeline internal installation equipment are relatively simple and cannot be installed quickly and reliably. Therefore, it is highly necessary to invent a rapid installation and locking device for the toroidal surface of a pipeline to quickly and reliably install equipment inside a pressure pipeline. Summary of the Invention

[0003] The purpose of the present invention is to provide a rapid installation and locking device for the toroidal surface of a pipeline, which solves the problem that existing pipeline internal installation equipment cannot install and seal pipelines quickly and reliably.

[0004] The technical solution adopted by the present invention to solve its technical problems is:

[0005] A rapid installation and locking device for the toroidal surface of a pipeline is installed on a working body through a third bolt. The device further includes a lock body, a locking pin, a runner, a pressing plate, a cylindrical locking marble, a handle, a first bolt, and a second bolt.

[0006] A locking pin hole penetrating the entire lock body is provided in the lock body, and a locking pin is fitted in the locking pin hole. A runner is provided in the groove between the lock body and the pressing plate.

[0007] Upper and lower convex columns are respectively provided on the upper and lower sides of the runner. A stud is provided at the axial center position on the upper side of the runner, and the stud is connected to the handle. Left and right concave holes are further provided on the runner. A pressing plate is sleeved on the stud and the upper convex column, and the pressing plate is connected to the lock body.

[0008] The locking pin has a cuboid structure, and a pin head with a cylindrical structure is provided at one end. A flat groove adapted to the outer diameter of the lower convex column is provided at a position perpendicular to the movement direction on the upper side of the locking pin.

[0009] A semicircular ring groove adapted to the outer diameter of the upper convex column is provided at a position close to the center of the pressing plate. A through hole adapted to the stud is provided at the center of the pressing plate. A lock hole is provided at a position opposite to the semicircular ring groove on the side of the through hole. A cylindrical locking marble is restrictedly provided in the lock hole, and a spring and a marble are provided in the cylindrical locking marble.

[0010] Furthermore, in order for the handle and the stud to be mutually adapted and not loosen, the stud is a multi-sided stud.

[0011] Further, in order to cooperate with the semi-circular ring groove to achieve the locking of the 180° rotation of the runner, the left concave hole and the right concave hole are symmetrically arranged with the stud as the center, and the two concave holes and the stud are on the same straight line.

[0012] Further, in order to prevent the marbles from coming out, the diameters of the left concave hole and the right concave hole are both smaller than the diameter of the marbles.

[0013] Further, for the convenience of disassembling the device, a plurality of countersunk threaded holes are also provided on the pressing plate, and the pressing plate is fixedly connected with the lock body through the first bolt.

[0014] Further, for the convenience of disassembling the device, the top end of the stud is fixedly connected with the handle through the second bolt.

[0015] The present invention constitutes a quick plugging and unplugging structure through a lock body, a locking pin, a runner, a pressing plate, a handle, a cylindrical locking marble and bolts, etc., so that the locking pin can be quickly inserted into the pipe annular surface and has the function of preventing the locking pin from retracting. The cylindrical locking marble can ensure the stability of the locking pin when it moves forward or retracts in place, prevent the locking pin from moving back and forth due to interference during work, which affects the fixing and disassembly of the working body, and can quickly and reliably seal the pressure pipeline.

Detailed implementation mode

[0026] Example, as Figures 1 to 4 shown, a rapid installation and locking device for the toroidal surface of a pipeline, which is installed on the working platform through the third bolt 9. The working platform includes a sealing surface or installation equipment installed on the toroidal surface of the pipeline. The device also includes a lock body 1, a locking pin 2, a runner 3, a pressure plate 4, a cylindrical locking ball 5, a handle 6, a first bolt 7, and a second bolt 8.

[0027] A locking pin hole 11 running through the entire lock body 1 is provided in the lock body 1. A locking pin 2 is fitted in the locking pin hole 11 to form a sliding guide rail mode. A runner 3 is provided in the groove between the lock body 1 and the pressure plate 4, and the runner 3 can rotate in the groove between the lock body 1 and the pressure plate 4.

[0028] As Figure 6 shown, upper convex columns 31 and lower convex columns 32 are respectively provided on the upper and lower sides of the runner 3. The upper convex column 31 is used to fit the semi-circular ring groove 41 on the pressure plate 4 and can move within the semi-circular ring groove 41; the lower convex column 32 is used to fit the flat groove 22 on the locking pin 2 and can move back and forth within the flat groove 22; a stud 33 is provided at the central axis position on the upper side of the runner 3. For the convenience of device disassembly, the handle 6 is fixedly connected to the stud 33 through the second bolt 8; in order to prevent slipping between the stud 33 and the handle 6, the stud 33 is a multi-sided stud, and hexagon, octagon and other studs can be used; in order to cooperate with the semi-circular ring groove 41 to realize the rotation locking of the runner 3, the left concave hole 34 and the right concave hole 35 on the runner 3 are symmetrical with respect to the stud 33, and the two concave holes and the stud 33 are on the same straight line. The two concave holes here are used to fit the ball 52 part of the cylindrical locking ball 5.

[0029] As Figure 5As shown in the figure, the locking pin 2 has a cuboid structure, and a pin head 21 with a cylindrical structure is provided at one end. The pin head 21 is used to be stuck in the pipe toroidal surface. The cylindrical structure of the pin head 21 facilitates reducing the friction force during the installation of the pin head and the pipe toroidal surface. At the same time, a linear groove 22 adapted to the outer diameter of the lower convex column 32 is provided at a position perpendicular to the movement direction on the upper side of the locking pin 2. Therefore, the semi-circular ring groove 41 of the runner 3, the pressure plate 4 and the linear groove 22 of the locking pin 2 cooperate with each other to realize the left and right reciprocating movement of the locking pin 2.

[0030] As Figure 7 shown, a pressure plate 4 is sleeved on the stud 33 and the upper convex column 31, and the pressure plate 4 is connected to the lock body 1. A semi-circular ring groove 41 adapted to the outer diameter of the upper convex column 31 is provided at a position of the pressure plate 4 close to the center of the circle, which is used to limit the sliding of the upper convex column 31 within a range of 180° in the semi-circular ring groove 41. A through hole 42 adapted to the stud 33 is provided at the center part of the pressure plate 4, and a lock hole 43 is provided at a position of the through hole 42 facing the semi-circular ring groove 41. In order to facilitate the disassembly of the device, a plurality of threaded counterbores 44 are further provided on the pressure plate 4, and the pressure plate 4 is fixedly connected to the lock body 1 through the first bolt 7.

[0031] As Figure 3 and Figure 8 shown, a cylindrical locking ball 5 is arranged in the lock hole 43. A spring 51 and a ball 52 are arranged in the cylindrical locking ball 5. In order to prevent the ball 52 from coming out, the diameters of the left concave hole 34 and the right concave hole 35 are both smaller than the diameter of the ball. The cylindrical locking ball 5 is used to lock the runner 3 and the pressure plate 4. When the handle is turned, the ball 52 rolls on the runner 3. When the handle is turned counterclockwise to the extreme position towards the pin head 21 end, the ball 52 is stuck into the left concave hole 34 of the runner 3 under the influence of the elastic force of the spring 51, thereby locking the runner 3 and preventing the locking pin 2 from retreating to hinder the installation process. When the handle is turned clockwise to the extreme position, the ball 52 is stuck into the right concave hole 35 of the runner 3 under the influence of the elastic force, thereby locking the runner 3 and preventing the locking pin 2 from advancing to hinder the disassembly process. Due to different torques, the forward and backward forces of the locking pin 2 are not sufficient to push the ball 52 out of the concave hole, while the force of turning the runner 3 with the handle 6 is sufficient to push the ball 52 out of the concave hole, thereby realizing the forward and backward movement of the locking pin 2.

[0032] When sealing a pipeline, several devices of the present invention are needed. The handle 6 of the device can be first rotated clockwise to the rightmost side and locked, then fixedly connected to the working platform through the third bolt 9 (or the device is an inseparable part of the working platform), and finally the handle is rotated counterclockwise to the leftmost side and locked, and the locking pin 2 is inserted into the pipe toroidal surface.

[0033] The present invention has been described exemplarily in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned manner. As long as various improvements are made by adopting the method concept and technical solution of the present invention, or directly applied to other occasions without improvement, they all fall within the protection scope of the present invention.
