[0022] Example:

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A water pipe splicing device includes a support frame 1, symmetrical support mechanisms are fixed to the left and right ends of the lower side of the support frame 1, and a moving mechanism is fixed to the upper side of the support frame 1. After the curved plate 4 fixes the water pipe 6, the moving mechanism can drive the two water pipes 6 to move closer, thereby facilitating the fixing of the flange at the water pipe installation location. A symmetrical cylinder 2 is fixed to the lower end of the two cylinders 2, and a strip plate 3 is fixed to the lower end of each of the two cylinders 2. An adjustment mechanism is provided inside the two strip plates 3. The adjustment mechanism can drive the two curved plates 4 to move closer together, thereby clamping and fixing the water pipe 6. A symmetrical arc-shaped plate 4 is fixed to the lower end of the mechanism, and a groove is provided on the side where the two arc-shaped plates 4 are close to each other. The inside of the groove is provided with evenly arranged adjusting wheels 5 that are rotated by an axle pin. When the adjusting wheel 5 is limited by the limiting mechanism, the adjusting wheel 5 does not rotate, and the resistance between the adjusting wheel 5 and the water pipe 6 is large. When the limiting effect is released, the adjusting wheel 5 can rotate, so that the water pipe 6 can rotate arbitrarily under force. The water pipe 6 is provided inside the two arc-shaped plates 4, and the side wall of the water pipe 6 is in contact with the side wall of the adjusting wheel 5. A limiting mechanism is provided inside the arc-shaped plate 4 on one side of the evenly arranged adjusting wheels 5.

[0025] The support mechanism includes a first support rod 7, which is fixedly connected to the lower side of the support frame 1. A second support rod 8 is slidingly arranged inside the first support rod 7. A fastening bolt is threadedly arranged at the lower end of the right side of the first support rod 7. The left end of the fastening bolt is clamped with the right side of the second support rod 8. The second support rod 8 and the first support rod 7 can cooperate with each other to extend and retract, thereby changing the height of the support frame 1.

[0026] The moving mechanism includes a horizontal plate 9, which is fixedly arranged at the upper end of the support frame 1. A moving groove is opened on the lower side of the horizontal plate 9. A first bidirectional screw rod 10 is arranged inside the moving groove through a bearing for rotation. A motor 11 is fixed to the right side of the horizontal plate 9. The right end of the first bidirectional screw rod 10 is fixedly connected to the output end of the motor 11. The rod wall of the first bidirectional screw rod 10 is threaded with symmetrical moving blocks 12. The upper ends of the two cylinders 2 are fixedly connected to the lower side of the moving block 12. The motor 11 uses a forward and reverse motor to drive the two moving blocks 12 to move closer or in opposite directions.

[0027] The adjusting mechanism includes a second bidirectional screw rod 13, which is rotatably arranged inside the strip plate 3 through a bearing. The front end of the second bidirectional screw rod 13 passes through the front side of the strip plate 3 and extends to the front end and is fixed with a rotating block 14. The rod wall thread of the second bidirectional screw rod 13 is provided with symmetrical adjusting rods 15. The upper sides of the two adjusting rods 15 are slidingly connected to the inner wall of the strip plate 3, and the lower ends of the two adjusting rods 15 are fixedly connected to the upper side of the curved plate 4. By rotating the rotating block 14, the rotating block 14 drives the second bidirectional screw rod 13 to rotate, and the second bidirectional screw rod 13 drives the two adjusting rods 15 of the rod wall to move closer, and the two adjusting rods 15 drive the lower curved plate 4 to move, thereby achieving clamping and fixation of the water pipe 6.

[0028] The limiting mechanism includes two screws 16, which are both threadedly connected to the side walls of the curved plate 4. The ends of the two screws 16 extending to the inside of the curved plate 4 are rotatably provided with a splint 17, and the ends of the two screws 16 extending to the outside of the curved plate 4 are fixed with a twist block. The two splints 17 are fixed with symmetrical limiting rods 18 on the sides facing away from each other. The symmetrical limiting rods 18 are both slidably connected to the side walls of the curved plate 4, and the sides of the two splints 17 that are close to each other are in contact with the side walls of the adjusting wheel 5. The limiting mechanism is used to limit and fix the evenly arranged adjusting wheels 5. When the water pipe 6 needs to be rotated, the limiting effect of the limiting mechanism on the adjusting wheel 5 is released.

[0029] The side walls of the two clamping plates 17 are fixed with a rubber anti-skid layer, which can increase the friction when the clamping plates 17 contact the adjusting wheel 5.

[0030] Working principle: When in use, the support frame 1 and the support mechanism are set up on the upper end of the water pipe 6, and the adjustment mechanism at the lower end and the arc plate 4 are located at both ends of the water pipe 6 through the cylinder 2. The two water pipes 6 are driven to move closer together through the adjustment mechanism, so as to clamp the water pipe 6. At this time, it is necessary to rotate the screw block, which drives the screw 16 on the side wall to move. The screw 16 drives the clamping plate 17 at the other end to clamp the water pipe 6 under the limiting action of the limiting rod 18. The water pipe 6 is pulled up by the contraction of the cylinder 2, and the water pipe 6 is pulled up by moving The mechanism is used to bring the ends of the two water pipes 6 that are close to each other closer, so that the flanges at the connection are fitted together. If the flange holes are not facing each other at this time, it is necessary to adjust the angle of the water pipe 6 and release the limit mechanism on the evenly arranged adjusting wheels 5. At this time, the adjusting wheels 5 can be rotated arbitrarily, and the resistance between them and the water pipe 6 is small. The water pipe 6 is directly rotated. After it is rotated to a suitable angle, the limit mechanism is continued to limit the evenly arranged adjusting wheels 5, and the flange holes facing the two water pipes 6 are connected and fixed by bolts.
