Technical Field

[0001] The utility model relates to the technical field of pipe threading machines, in particular to a polyurethane prefabricated directly buried thermal insulation pipe threading machine. Background Art

[0002] The direct-buried insulated pipe threading machine is a supporting equipment for underground pipe threading. The pipe threading machine can install water pipes without damaging the road. The installation speed is faster and more convenient for people to use. With the continuous development of science and technology, people's requirements for the manufacturing process of the direct-buried insulated pipe threading machine are getting higher and higher.

[0003] However, some of the traditional pipe threading machines currently used still have disadvantages. For example, the pipes cannot be protected during threading. When the pipes enter the holes, the outer wall of the insulation pipes may be scratched or squeezed, which will reduce the insulation performance of the insulation pipes.

[0004] In view of this, the utility model solves the above technical problems by proposing a polyurethane prefabricated direct-buried thermal insulation pipe threading machine. Utility Model Content

[0005] In response to the shortcomings of the above-mentioned background technology, the utility model provides a technical solution for a polyurethane prefabricated direct-buried insulated pipe threading machine. When the insulated pipe enters, the lower protective arc plate and the upper protective arc plate also enter, thereby protecting the insulated pipe and avoiding scratches, solving the problems raised in the above-mentioned background technology.

[0006] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0007] As a preferred technical solution of the present invention, a hydraulic rod is fixed to one side of the fixed plate, and a pushing plate is fixed to the telescopic end of the hydraulic rod.

[0008] As a preferred technical solution of the present invention, infrared sensors are fixed inside the lower protective arc plate and the upper protective arc plate, and two scraping plates are fixed on one side of the lower protective arc plate and the upper protective arc plate.

[0009] As a preferred technical solution of the present invention, protective pads are fixed to the inner walls of the lower protective arc plate and the inner walls of the upper protective arc plate.

[0010] As an optimal technical solution of the present invention, two sliding frames are fixed on the top of the support platform, and a moving block is slidably installed inside the sliding frame. A fixed rod is fixed on the top of the moving block, and a positioning ring is fixed between the fixed rods. A push rod is fixed on one side of the moving block, and one end of the push rod passes through the sliding frame.

[0011] As a preferred technical solution of the present invention, a support column is fixed to the bottom of the support platform, and a stabilizing pad is fixed to the bottom of the support column.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, the connecting rod can be moved up and down by rotating the nut, so that the lower protective arc plate and the upper protective arc plate can clamp and fix the insulation pipe, and the adjustable design can adapt to insulation pipes of various sizes, thereby improving flexibility. After clamping, the output end of the driving motor rotates to drive the rotating roller to rotate, thereby pushing the support plate forward, thereby driving the insulation pipe into the hole;

[0014] At the same time, the movement of the telescopic end of the electric push rod drives the sliding block to move, which is conducive to the smoother entry of the insulation pipe into the hole, and also avoids jamming. It can also expand the distance range of the insulation pipe entering the hole. When the insulation pipe enters, the lower protective arc plate and the upper protective arc plate also enter, thereby protecting the insulation pipe and avoiding scratches. When it reaches the specified position, the upper protective arc plate can be moved up by rotating the nut, so there will be a gap between the upper and lower protective arc plates. At this time, the lower and upper protective arc plates are driven out of the hole by the electric push rod. Therefore, the insulation pipe is protected while being installed, which is conducive to subsequent stable operation and avoids the decline of insulation performance.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1:

[0022] See also Figure 1-4 The present invention relates to a polyurethane prefabricated direct-buried thermal insulation pipe threading machine, comprising: a support platform 1, a driving frame 2 is fixed on the top of the support platform 1, a plurality of driving motors 3 are fixed inside the driving frame 2, a rotating roller 4 is fixed on the output end of the driving motor 3, a support plate 5 is slidably installed above the driving frame 2, a lower protective arc plate 6 is slidably installed inside the support plate 5, the top of the support plate 5 is provided with two sliding grooves 7, a connecting hole 8 is provided on one side of the inner wall of the sliding groove 7, a sliding block 9 is slidably installed inside the sliding groove 7, a nut 10 is rotatably installed on the top of the sliding block 9, and the internal thread of the nut 10 is connected to a connecting rod 11, one end of the connecting rod 11 extends to the inside of the sliding block 9, an upper protective arc plate 12 is fixed between the connecting rods 11, a plurality of mounting rods 13 are fixed on one side of the sliding block 9, one end of the mounting rod 13 is fixed to the outer wall of the lower protective arc plate 6, a fixing plate 14 is fixed on the top of the support platform 1, and two electric push rods 15 are fixed on one side of the fixing plate 14, and the telescopic end of the electric push rod 15 is fixedly connected to one side of the sliding block 9.

[0023] During use, the connecting rod 11 can be moved up and down by rotating the nut 10, so that the lower protective arc plate 6 and the upper protective arc plate 12 can clamp and fix the insulation pipe, and the adjustable design can adapt to insulation pipes of various sizes, thereby improving flexibility. After clamping, the output end of the driving motor 3 rotates to drive the rotating roller 4 to rotate, thereby pushing the support plate 5 to move forward, thereby driving the insulation pipe into the hole. At the same time, the sliding block 9 is driven to move by the telescopic end of the electric push rod 15, which is conducive to the insulation pipe entering the hole more smoothly, and It also avoids jamming and can expand the distance range of the insulation pipe entering the hole. When the insulation pipe enters, the lower protective arc plate 6 and the upper protective arc plate 12 also enter, thereby protecting the insulation pipe and avoiding scratches. When it reaches the specified position, the upper protective arc plate 12 can be moved up by rotating the nut 10, so that a gap will be generated between the upper protective arc plate 12 and the lower protective arc plate 6. At this time, the lower protective arc plate 6 and the upper protective arc plate 12 are driven out of the hole by the electric push rod 15. Therefore, the insulation pipe is protected while the installation is achieved, which is conducive to subsequent stable operation and avoids the decline of insulation performance.

[0024] Example 2:

[0025] As a specific embodiment of the present invention, please refer to Figure 1-4 As shown, a hydraulic rod 16 is fixed to one side of the fixed plate 14, a push plate 17 is fixed to the telescopic end of the hydraulic rod 16, infrared sensors 18 are fixed to the inside of the lower protective arc plate 6 and the inside of the upper protective arc plate 12, two scraping plates 19 are fixed to one side of the lower protective arc plate 6 and one side of the upper protective arc plate 12, and protective pads 20 are fixed to the inner wall of the lower protective arc plate 6 and the inner wall of the upper protective arc plate 12.

[0026] During use, the telescopic end of the hydraulic rod 16 drives the pushing plate 17 to contact the insulation pipe, thereby ensuring that the insulation pipe can always maintain the same position with the lower protective arc plate 6 and the upper protective arc plate 12, avoiding the deviation of the position of the insulation pipe and the lower protective arc plate 6 and the upper protective arc plate 12 due to shaking during movement, thereby improving the protection effect. When threading the pipe, the infrared sensor 18 can detect the situation in the hole. When an obstacle occurs, the pipe threading is stopped in time to avoid damage to the insulation pipe. At the same time, some sharp objects in the hole are scraped by the scraping plate 19, thereby reducing the sharpness of the object, which is beneficial for the insulation pipe to be safer and more stable during operation and extend its service life. The protective pad 20 can buffer the extrusion force to avoid damage to the insulation pipe, which will help increase friction, improve stability and reduce the risk of falling off.

[0027] Example 3,

[0028] As a specific embodiment of the present invention, please refer to Figure 1-4 As shown, two sliding frames 21 are fixed on the top of the support platform 1, and a moving block 22 is slidably installed inside the sliding frame 21. A fixing rod 23 is fixed on the top of the moving block 22, and a positioning ring 24 is fixed between the fixing rods 23. A pushing rod 25 is fixed on one side of the moving block 22, and one end of the pushing rod 25 passes through the sliding frame 21. A supporting column 26 is fixed to the bottom of the support platform 1, and a stabilizing pad 27 is fixed to the bottom of the support column 26.

[0029] During use, the moving block 22 can be pushed to move by the push rod 25, thereby driving the fixed rod 23 to move, and then driving the positioning ring 24 to align with the hole where the pipe needs to be inserted, thereby improving the accuracy of pipe insertion. The support column 26 and the stabilizing pad 27 can make the support platform 1 more stable during pipe insertion, avoiding shaking, and preventing skewness during pipe insertion.
