DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-5 , a foldable pressure pipe sealing machine includes a mounting plate 1, a mounting frame 2 is fixedly installed on the outer wall of the mounting plate 1, and a fixing plate 3 is fixedly installed on the outer walls of both sides of the mounting frame 2. The outer walls of the two fixing plates 3 are threadedly installed with fixing bolts 4 through fixing holes, and the outer walls of the two fixing bolts 4 are fixedly installed with nuts 5 that cooperate with the mounting plate 1. A connecting sleeve 7 is slidably installed inside the mounting frame 2 through a telescopic mechanism. The telescopic mechanism includes a hydraulic cylinder 6 fixedly installed inside the mounting frame 2, and the telescopic end of the hydraulic cylinder 6 is slidably connected to the inner wall of the connecting sleeve 7. The telescopic end of the hydraulic cylinder 6 is provided with a jack that cooperates with the fixing pin 9. A sealing device 8 is fixedly installed on the outer wall of the connecting sleeve 7, and a fixing pin 9 is slidably installed on the inner wall of the connecting sleeve 7. A dial block 10 is fixedly installed on the end of the fixing pin 9. The bottom wall of the dial block 10 is connected to the outer wall of the connecting sleeve 7 through a fixing mechanism. The fixing mechanism includes a fixing spring 11 fixedly installed on the outer wall of the fixing pin 9, and both ends of the fixing spring 11 are elastically connected to the outer wall of the connecting sleeve 7 and the bottom wall of the dial block 10 respectively.

[0023] The inner wall of the mounting plate 1 is fixedly mounted with two fixing rods 13 through two connecting frames 12, and the outer walls of the two fixing rods 13 are rotatably mounted with connecting blocks 14, and the outer walls of the two connecting blocks 14 are fixedly mounted with support frames 16 through a connecting mechanism. The connecting mechanism includes two connecting rods 15 fixedly mounted on the outer wall of the connecting block 14, and the ends of the two connecting rods 15 are fixedly connected to the outer wall of the support frame 16. The inner walls of the two support frames 16 are rotatably mounted with double-headed screws 17, and the upper end surfaces of the two support frames 16 are fixedly mounted with motors 18 connected to the double-headed screws 17 on the same side. The outer walls of the two double-headed screws 17 are threaded with two through a limiting mechanism. The movable sleeve 20 and the limiting mechanism include a limiting rod 19 fixedly mounted on the inner wall of the support frame 16. The limiting rod 19 slides through the two movable sleeves 20. The limiting rod 19 can limit the two movable sleeves 20 so that the two movable sleeves 20 can only move axially along the outer wall of the double-headed screw 17. A clamping block 21 is fixedly mounted on the outer wall of each movable sleeve 20, and an anti-slip pad 22 is fixedly mounted on the inner wall of each clamping block 21. Each anti-slip pad 22 is made of rubber. The rubber material has good elasticity and softness, which enables it to form a closer contact between the surface and the object, thereby increasing friction and improving the friction coefficient.

[0024] When the utility model is used, the pipe is placed between the clamping blocks 21, and then the two motors 18 can drive the two double-headed screws 17 on the same side to rotate. When the two double-headed screws 17 rotate, they can drive the two clamping blocks 21 to move relative to each other through the cooperation with the limit rods 19 on the same side, and clamp the pipe by the cooperation of the anti-slip pads 22. The anti-slip pads 22 can increase the friction between the outer wall of the pipe and the clamping blocks 21, thereby increasing the clamping effect. When the pipe is clamped and fixed, the connecting sleeve 7 can be driven to move under the telescopic action of the hydraulic cylinder 6. When the connecting sleeve 7 moves, it can drive the blocking device 8 to block the required blocked part, thereby realizing the blocking work of the pipe. When it is necessary to block the damaged parts of pipes of different sizes or shapes, the dial block 10 can be dialed to drive the fixing pin 9 to be pulled out of the insertion hole, thereby releasing the fixation of the connecting sleeve 7, and then the connecting sleeve 7 can be pulled out from the outer wall of the hydraulic cylinder 6, thereby realizing the convenient replacement of blocking devices 8 of different sizes and shapes;

[0025] When the sealing work is completed, the nut 5 can be turned to release the fixing bolt 4, and then the fixing bolt 4 can be turned to remove the fixing bolt 4 from the fixing plate 3 and the mounting plate 1, thereby the hydraulic cylinder 6 inside the mounting frame 2 can be disassembled, thereby realizing the disassembly and assembly of the sealing device 8, and then the connecting block 14 can be rotated to drive the connecting rod 15 to rotate, and when the connecting rod 15 rotates, the support frame 16 on the same side can be driven to rotate, thereby the rotation of the support frame 16 can drive the clamping block 21 to rotate, thereby realizing the folding and disassembly of the entire pipe sealing machine, which can facilitate the carrying and installation of the pipe sealing machine. The entire pipe sealing machine is in a vertical state with the mounting plate 1 when in use and in a parallel state when not in use.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
