[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-2 In an embodiment of the utility model, a pressure pipe installation and docking device includes a workbench 1, which provides a working place for the installation and docking of the pressure pipe. A fixed clamping member 2 and a dynamic clamping member 3 are arranged on the upper surface of the workbench 1. The fixed clamping member 2 and the dynamic clamping member 3 can clamp the pressure pipe and make a pressure hook move to the dynamic clamping member 3 close to the fixed clamping member 2 to realize the installation and docking of two pressure pipes.

[0024] See also Figure 1-3 The fixed clamping member 2 and the dynamic clamping member 3 both include a fixed clamping plate 4 and a movable clamping plate 5 used in conjunction with each other. The movable clamping plate 5 is located above the fixed clamping plate 4, and a first cylinder 7 and a second cylinder 8 are respectively arranged above the two movable clamping plates 5. The piston rod ends of the first cylinder 7 and the second cylinder 8 are fixedly connected to the movable clamping plate 5. The first cylinder 7 and the second cylinder 8 make the piston rod push the movable clamping plate 5 down to cooperate with the fixed clamping plate 4 to clamp the pressure pipe.

[0025] See also Figure 1-3 The fixed splint 4 and the movable splint 5 are both provided with an inclined groove 6 on the side where they are close to each other. The inclined groove 6 of the fixed splint 4 is set so that the axis point of the pressure pipe and the lowest point of the inclined groove 6 are on the same longitudinal vertical line, that is, the two pressure pipes are automatically aligned in the horizontal direction. The setting of the inclined groove 6 of the fixed splint 4 and the movable splint 5 enables the fixed splint 4 and the movable splint 5 to cooperate in clamping pressure pipes of different diameters, and the setting of the inclined groove 6 relative to the setting of the inferior arc increases the number of contact surfaces between the fixed splint 4, the movable splint 5 and the pressure pipe, and can apply force not only in the longitudinal direction, but also has a better clamping effect.

[0026] See also Figure 1-3 A plurality of clamping blocks 9 are provided on one side of the two movable clamping plates 5 located on the inclined groove 6. The clamping blocks 9 first contact the pressure pipe and apply a vertical downward clamping force to the pressure pipe to pre-position the pressure pipe. Because when the movable clamping plate 5 moves downward to clamp the pressure pipe, there will be two contact surfaces with the pressure pipe, which may easily cause the pressure pipe to shift in position during the process of the movable clamping plate 5 gradually moving downward and applying force.

[0027] See also Figure 3 In order to realize the clamping effect of the above-mentioned clamping block 9, the upper end of the clamping block 9 is rotatably connected with a threaded rod 10, the upper end of the threaded rod 10 passes through the movable clamping plate 5, and the outer surface of the threaded rod 10 is threadedly connected to the movable clamping plate 5. The pressure pipeline squeezes the clamping block 9 to make the threaded rod 10 move upward, and a thread force is generated between the threaded rod 10 and the movable clamping plate 5 when it moves upward. At this time, the threaded rod 10 rotates with the clamping block 9, and the thread force generates resistance to the movement of the threaded rod 10, thereby blocking the rising of the clamping block 9, thereby clamping and fixing the pressure pipeline.

[0028] In addition, the threaded rod 10 and the clamping block 9 are rotatably connected via a bearing. The provision of the bearing reduces the friction between the threaded rod 10 and the clamping block 9 and prevents the clamping block 9 from rotating with the rotation of the threaded rod 10 .

[0029] See also Figure 3 The two movable clamps 5 are provided with a plurality of placement grooves 11 on one side of the inclined groove 6, and the outer surface of the clamping block 9 fits with the inner wall of the placement groove 11. The placement groove 11 is used for the clamping block 9 to avoid the difficulty of the movable clamp 5 to clamp the pressure pipe due to the protrusion of the clamping block 9.

[0030] See also Figure 2 In order to realize the movement of the dynamic clamping member 3, a slider 12 is provided on the upper surface of the workbench 1, and the dynamic clamping member 3 is located above the slider 12. A slide groove 13 corresponding to the position of the slider 12 is opened on the upper surface of the workbench 1. A third cylinder 15 is fixedly provided at one end of the slide groove 13 close to the fixed clamping member 2. The piston rod end of the third cylinder 15 is fixedly connected to the slider 12. After the fixed clamping member 2 and the dynamic clamping member 3 clamp the pressure pipeline, the third cylinder 15 is started to make the piston rod drive the slider 12 to slide along the slide groove 13 to make the dynamic clamping member 3 close to the fixed clamping member 2, that is, the two pressure pipelines are brought close to each other, and then the pressure pipelines are docked.

[0031] See also Figure 2 The slider 12 is fixedly connected to limit blocks 17 at both ends near the slide groove 13, and a limit groove 18 corresponding to the position of the limit block 17 is opened on the inner side of the slide groove 13. When the third cylinder 15 drives the slider 12 to slide along the slide groove 13, the limit block 17 slides along the limit groove 18. The setting of the limit block 17 and the limit groove 18 prevents the slider 12 from escaping from the slide groove 13.

[0032] See also Figure 1-3 A connecting block 14 is fixedly connected to the lower surface of the two fixed splints 4. The two connecting blocks 14 are fixedly connected to the upper surface of the workbench 1 and the slider 12 respectively. The setting of the connecting block 14 is used to realize the connection between the fixed splints 4 and the workbench 1 and the slider 12.

[0033] See also Figure 1-2 An L-shaped support frame 16 is fixed to the positions of the fixed clamping member 2 and the movable clamping member 3 corresponding to the upper surface of the workbench 1 and the upper surface of the slider 12. The first cylinder 7 and the second cylinder 8 are respectively located on the upper surfaces of the two L-shaped support frames 16. The L-shaped support frame 16 is used to support the first cylinder 7 and the second cylinder 8.

[0034] The working principle and use process of the utility model are as follows: when in use, two pressure pipes are placed on the fixed clamping member 2 and the fixed clamping member 3, respectively. The inclined groove 6 of the fixed clamping member 4 is arranged so that the axis point of the pressure pipe and the lowest point of the inclined groove 6 are on the same longitudinal vertical line, that is, the two pressure pipes are automatically aligned in the horizontal direction, and the first cylinder 7 and the second cylinder 8 are respectively started to make the piston rod push the movable clamping plate 5 to descend and cooperate with the fixed clamping plate 4 to clamp the pressure pipe. During the descent of the movable clamping plate 5, the clamping block 9 first contacts the pressure pipe, and the pressure pipe squeezes the clamping block 9 to make the threaded rod 10 move upward. The threaded rod 10 moves upward and generates a thread force between the movable clamping plate 5 and the movable clamping plate 5. At this time, the threaded rod 10 rotates on the clamping block 9, and the thread force generates resistance to the movement of the threaded rod 10, thereby blocking the rising of the clamping block 9, thereby clamping and fixing the pressure pipe. The holding block 9 first clamps and applies a vertical downward clamping force to the pressure pipe to pre-position the pressure pipe. Because when the movable clamp 5 moves down to clamp the pressure pipe, there will be two contact surfaces with the pressure pipe, which may easily cause the pressure pipe to shift in position during the gradual downward movement of the movable clamp 5. The setting of the inclined groove 6 of the fixed clamp 4 and the movable clamp 5 enables the fixed clamp 4 and the movable clamp 5 to cooperate to clamp pressure pipes of different diameters, and the setting of the inclined groove 6 relative to the setting of the inferior arc increases the number of contact surfaces between the fixed clamp 4 and the movable clamp 5 and the pressure pipe, so that force can be applied not only in the longitudinal direction, but also with a better clamping effect. After the fixed clamp 2 and the movable clamp 3 clamp the pressure pipe, the third cylinder 15 is started to make the piston rod drive the slider 12 to slide along the slide groove 13 to make the movable clamp 3 close to the fixed clamp 2, so that the two pressure pipes are close to each other, and then the pressure pipes are docked.

[0035] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
