[0002] With the popularization of power systems, electric energy has become an indispensable part of people's daily lives. Electric pipes are a kind of pipeline system specially used for the transmission and distribution of electric energy. Electric pipes are widely used because of their convenient connection and simple maintenance. Electric pipes play a vital role in urban and rural power grids. When processing and using electric pipes, it is usually necessary to heat-melt two electric pipes to connect and fix the two electric pipes. When hot-melting the electric pipes, it is often necessary to use a butt fixing device to fix the electric pipes on both sides and move the two electric pipes to make them butt;

[0003] At present, in the prior art, the power pipe is usually clamped and fixed by a mechanical clamp, but the power pipe is usually made of PE (modified polyethylene), which causes the power pipe to deform or even collapse under the clamping of the mechanical clamp, thereby affecting the normal hot-melt connection of the power pipe. At the same time, the power pipe often shakes during hot-melt connection, making it difficult to fix the power pipe, which can easily cause the power pipe to tilt during hot-melt connection. After the hot-melt connection is completed, smoke and dust generated by the hot-melting of the power pipe will gather around the power pipe, affecting the staff's field of vision and resulting in low connection efficiency. Summary of the invention

[0004] In order to solve the deficiencies in the prior art, the present invention provides a device and a method for hot-melt butt jointing of electric pipes to solve the problem of collapse under the above-mentioned strong clamping, thereby affecting the normal hot-melt butt jointing of the electric pipes. At the same time, the device can clamp the electric pipes while they are being butt jointed to prevent the electric pipes from shaking during hot-melting. After the hot-melt butt jointing of the electric pipes is completed, the device can blow away the smoke and odor generated by the hot-melting of the electric pipes.

[0015] First, insert the two ends of the two power pipes into the inside of the clamping rings through the notches on the two clamping rings, so that the inner circumference of the telescopic airbag is in contact with the power pipes;

[0016] Then the power pipes on the clamping ring are moved to fit together and fastened by the telescopic airbag;

[0017] Hot-melt the butted power pipes;

[0018] The telescopic airbag releases the power pipe after the hot melt connection, and removes the power pipe from the notch on the clamping ring.

At the same time, after the telescopic airbag expands, the notch will shrink to prevent the power pipe from falling off from the inside of the clamping ring, so that the power pipe can be clamped in advance during the process of moving and docking the power pipe, and the power pipe is prevented from shaking or even falling off during the hot melting process, which saves labor costs, simplifies the operation steps, and improves the efficiency of docking the power pipe.

[0027] At the same time, the telescopic airbag adjusts the degree of clamping with the power pipe by inflating, expanding, deflating and contracting. The telescopic airbag then adjusts the degree of inflation and deflation according to the power pipes of different radii, so that the clamping structure always clamps the power pipe, improving versatility. At the same time, the splint further improves the tightness and stability of the clamping structure and the power pipe and prevents scratches and collapse of the power pipe caused by strong clamping.

[0028] At the same time, the inflation structure and the exhaust structure of the present invention are used in conjunction with each other, so that when the device loosens the power pipe by moving the stand, the volumes of the first inner cavity and the second inner cavity inside the gas box also change, so that the gas in the second cavity is discharged from the exhaust port. The gas discharged from the exhaust port will disperse the exhaust gas generated by the power pipe after docking to prevent obstruction of the staff's line of sight, and the power pipe after hot melting will be quickly cooled, condensed and fixed, further improving the efficiency of power pipe docking.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more schemes or examples in a suitable manner.

[0041] like Figure 1-4 As shown, the present invention provides an electric pipe hot-melt butt joint device and a method for using the same, wherein the electric pipe hot-melt butt joint device comprises: a linear moving module 1 and a stand 2, wherein the linear moving module 1 comprises: a mounting platform 11 and a moving structure 12, wherein the moving structure 12 is arranged on the upper outer surface of the mounting platform 11, wherein slide grooves 13 are arranged on both sides of the top of the moving structure 12, wherein the slide grooves 13 on both sides are slidably connected to the bottom of the stand 2, wherein a clamping structure 3 is arranged on the top of the stand 2, wherein the centers of the two clamping structures 3 pass through an electric pipe to clamp and fix the electric pipe, wherein an inflatable structure 4 is arranged on the side of the top of the moving structure 12 corresponding to the two slide grooves 13 away from each other, wherein the inflatable structure 4 is connected to the clamping structure 3, and wherein two exhaust structures 5 are symmetrically arranged on the center of the top of the moving structure 12, wherein the exhaust structure 5 is connected to the inflatable structure 4.

[0042] like Figure 1As shown, the stand 2 is used to support and move the clamping structure 3. The stand 2 includes: a slider 21, a constraint sheet 22, a support rod 23 and a support plate 24. The slider 21 is arranged in the slide groove 13 of the moving structure 12 on the linear moving module 1. The slider 21 can slide along the slide groove 13. The upper part of the slider 21 is fixedly connected to the bottom of the constraint sheet 22, and the top of the constraint sheet 22 is fixedly connected to the bottom of the support rod 23. The constraint sheet 22 prevents the stand 2 from tilting when moving on the linear moving module 1, thereby improving stability. At the same time, the top of the support rod 23 is fixedly connected to the support plate 24, and the top of the support plate 24 is fixedly connected to the clamping structure 3.

[0043] Preferably, the stand 2 is driven by a motor so that the slider 21 on the stand 2 can move left and right along the slide groove 13 .

[0044] like Figure 1 and Figure 2 As shown, the clamping structure 3 includes: a clamping ring 31, a telescopic airbag 33, a clamping plate 34, a hose 35 and a supporting sheet 36, wherein the bottom of the supporting sheet 36 is fixedly connected to the top outer surface of the supporting plate 24 on the stand 2, and the top of the supporting sheet 36 is fixedly connected to the bottom outer surface of the clamping ring 31, and a through slot 32 is arranged on one side of the outer peripheral surface of the clamping ring 31, the inner peripheral surface of the clamping ring 31 is connected to the telescopic airbag 33, and a hose 35 is arranged inside the support rod 23 on the stand 2. The hose 35 is elastic and can stretch and shrink. The top of the hose 35 passes through the clamping ring 31 and is connected to the telescopic airbag 33, and the bottom of the hose 35 extends from the inner wall of the support rod 23 and is connected to the inflatable structure 4. One end of the hose 35 moves left and right with the telescopic airbag 33 on the stand 2 and the other end is fixedly constrained by the inflatable structure 4, so that the hose 35 can stretch and shrink with the movement of the stand 2.

[0045] The inner circumference of the telescopic airbag 33 is provided with clamping plates 34 at intervals. The clamping plates 34 are made of rubber. When the telescopic airbag 33 expands and clamps the power pipe, the clamping plates 3 and the power pipe are in close contact and the clamping plates 3 will deform along with the telescopic airbag 33. The gaps between all the clamping plates 3 are reduced. When the telescopic airbag 33 is fully expanded, all the clamping plates 3 are completely in close contact with each other, and the power pipe is further sealed and fixed. The arrangement of the clamping plates 34 improves the sealing and stability of the clamping structure 3 when clamping the power pipe. Moreover, the interval arrangement of the clamping plates 3 can not only meet the sealing and fixing of the power pipe, but also avoid the local deformation imbalance when the clamping plates 3 deform along with the telescopic airbag 33.

[0046] At the same time, a notch 32 is provided on the same side of the clamping ring 31 and the telescopic airbag 33, and an anti-wear strip is provided on the outer surface of the notch 32. The notch 32 is provided to facilitate the insertion of the power pipe into the clamping ring 31, and the anti-wear strip avoids the outer surface of the power pipe from being worn and scratched. The telescopic airbag 33 adjusts the degree of clamping with the power pipe by inflating, expanding, exhausting and contracting. The telescopic airbag 33 can adjust the degree of inflation and deflation according to the power pipes of different radii, so that the clamping structure 3 always clamps the power pipe, thereby improving versatility.

[0047] The interior of the telescopic airbag 33 is equipped with memory foam, which improves the return performance of the telescopic airbag 33.

[0048] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the inflatable structure 4 includes: a gas box 41, a piston rod 42, a first one-way valve 43, a second one-way valve 44, a spring 45, a sub-rod 46, a sliding plate 47, a first inner cavity 48 and a second inner cavity 49, wherein the gas box 41 is a box-shaped structure, the bottom outer surface of the gas box 41 is connected to the top outer surface of the moving structure 12 on the linear moving module 1, the gas box 41 is provided with a through opening toward the side of the stand 2, the opening is adaptively matched with one end of the piston rod 42, one end of the piston rod 42 passes through the opening and is connected to the stand 2, the other end of the piston rod 42 is fixedly connected to the sliding plate 47, and the sliding plate 47 divides the inside of the gas box 41 into a first cavity 48 and a second cavity 49. The first cavity 48 and the second cavity 49 are not connected, the first cavity 48 is located on the right side of the second cavity 49, and then the volumes of the first cavity 48 and the second cavity 49 are controlled by moving the sliding sheet 47 to inflate and exhaust. The upper part of the first cavity 48 is connected to the hose 35, and the first one-way valve 43 and the second one-way valve 44 are set on the outer surface of the gas box 41 away from the side of the stand 2. The first one-way valve 43 is located on the upper side of the second one-way valve 44, and both the first one-way valve 43 and the second one-way valve 44 are connected to the second cavity 49 inside the gas box 41. The second one-way valve 44 can only exhaust one-way but not intake air, and the first one-way valve 43 can only intake air one-way but not exhaust air.

[0049] like Figure 4 As shown, the piston rod 42 is internally slidably connected with a secondary rod 46, one end of a spring 45 is connected to the outer surface of the secondary rod 46, and the other end of the spring 45 is connected to the outer surface of a sliding plate 47. The end of the secondary rod 46 away from the spring 45 is connected to the stand 2. The sliding plate 47 is controlled to move inside the gas box 41 through the movement of the stand 2, and the airflow inside the gas box 41 is discharged into the interior of the telescopic airbag 33, thereby adjusting the expansion and contraction degree of the telescopic airbag 33.

[0050] like Figure 1 and Figure 2As shown, the exhaust structure 5 is used to discharge the gas in the gas box 41, and then blow away the exhaust gas generated by the hot-melt butt joint of the power pipe. The exhaust structure 5 includes: a bellows 51, a fixed rod 52 and an exhaust port 53, wherein one end of the bottom of the fixed rod 52 is fixedly connected to the central outer surface of the top of the mobile structure 12, and is used to support the exhaust port 53. The fixed rod 52 is located in the middle of the two slide grooves 13, and the top of the fixed rod 52 is fixedly connected to the exhaust port 53. One side of the bottom of the exhaust port 53 is connected to one end of the bellows 51, and the other end of the bellows 51 passes through the interior of the mobile structure 12 and is connected to the second one-way valve 44 on the inflatable structure 4. The exhaust port 53 is set in the center of the mobile structure 12, which is convenient for the telescopic airbag 33 to loosen the power pipe after hot-melt butt joint, and the gas discharged from the exhaust port 53 blows away the exhaust gas generated by the hot-melt of the power pipe, and is also conducive to the rapid condensation and fixation of the power pipe after hot-melt.

[0051] In a specific embodiment, the stand 2 drives the slider 21 through a motor to slide along the slide groove 13 toward the center of the mobile structure 12. During the movement of the stand 2, the auxiliary rod 46 connected to it will be pulled to move synchronously, and the auxiliary rod 46 drives the piston rod 42 to move synchronously. The piston rod 42 will pull the sliding plate 47 to move synchronously toward the center of the mobile structure 12. The volume of the second cavity 49 increases to form a pressure difference, so that the second cavity 49 inhales external air through the first one-way valve 43 to stabilize the pressure. At the same time, the volume of the first cavity 48 decreases, and the gas inside the first cavity 48 is discharged through the upper hose 35. The gas in the hose 35 enters the telescopic airbag 33, causing the telescopic airbag 33 to expand and tighten the power pipe, making the power pipe more stable during hot-melt connection and avoiding shaking when the power pipe is docked.

[0052] When the electric pipe is to be released, the platform 2 drives the slider 21 through the motor to slide along the slide groove 13 away from the central direction of the moving structure 12. During the movement of the platform 2, the auxiliary rod 46 connected to it will be pushed to move synchronously, and the auxiliary rod 46 drives the piston rod 42 to move synchronously. The piston rod 42 will push the sliding piece 47 to move synchronously away from the central direction of the moving structure 12. At this time, the volume of the second cavity 49 becomes smaller, and the second cavity 49 discharges the gas in the second cavity 49 through the second one-way valve 44. The second one-way valve 44 is connected to the bellows 51, and the gas is discharged from the exhaust port 53 via the bellows 51. The gas discharged from the exhaust port 53 will blow away the exhaust gas generated by the electric pipe after docking to prevent obstruction of the staff's line of sight, so that the hot-melted electric pipe is quickly cooled, condensed and fixed. At the same time, the volume of the first cavity 48 increases to form a pressure difference, so that the first cavity 48 sucks the gas in the telescopic airbag 33 into the first cavity 48 through the upper hose 35. The telescopic airbag 33 contracts to release the electric pipe, making it convenient for the staff to remove the electric pipe.

[0053] In another specific embodiment, when the sliding piece 47 follows the stand 2 to move toward the center of the movable structure 12 until the sliding piece 47 is in contact with the inner wall of the gas box 41, the piston rod 42 is constrained to stop moving, and the stand 2 continues to move. The spring 45 is stretched and deformed so that the auxiliary rod 46 can continue to follow the movement of the stand 2, avoiding pulling on the stand 2, which makes the stand 2 unable to move.

[0054] The present invention also provides a method for using the power pipe hot-melt butt-jointing device, comprising the following steps:

[0055] Step 1: First, insert the two ends of the two power pipes into the inside of the clamping rings 31 through the notches 32 on the two clamping rings 31, and the inner circumference of the telescopic airbag 33 is in contact with the power pipes;

[0056] Step 2: Then move the power pipes on the clamping ring 31 to abut against each other, and tighten the power pipes through the telescopic airbag 33;

[0057] Step 2.1: Start the motor on the linear motion module 1 to drive the slider 21 to move along the slide slot 13 toward the center of the moving structure 12;

[0058] Step 2.2: The stand 2 pulls the auxiliary rod 46 on the inflatable structure 4 to move synchronously, and the auxiliary rod 46 drives the piston rod 42 to follow the movement, and the piston rod 42 pulls the sliding sheet 47 to move synchronously;

[0059] Step 2.3: When the sliding sheet 47 moves toward the center of the moving structure 12, the volume of the second cavity 49 increases to form a pressure difference, so that the second cavity 49 inhales external air through the first one-way valve 43 to stabilize the pressure;

[0060] Step 2.4: At the same time, the volume of the first cavity 48 decreases, and the gas inside the first cavity 48 is discharged into the telescopic airbag 33 through the upper hose 35, so that the telescopic airbag 33 expands to tighten the power pipe.

[0061] Step 2.5: Continue to move the stand 2 until the two ends of the power pipes on the two clamping rings 31 are butted against each other;

[0062] Step 3: Hot-melt the butted power pipes;

[0063] Step 4: The telescopic airbag 33 releases the power pipe after the hot-melt connection, and removes the power pipe from the notch 32 on the clamping ring 31;

[0064] Step 4.1: Start the motor on the linear motion module 1 to drive the slider 21 to slide along the slide slot 13 away from the center of the moving structure 12;

[0065] Step 4.2: During the movement of the platform 2, the auxiliary rod 46 connected thereto will be pushed to move synchronously, the auxiliary rod 46 will drive the piston rod 42 to move synchronously, and the piston rod 42 will push the sliding sheet 47 to move synchronously;

[0066] Step 4.3: The sliding sheet 47 moves away from the center of the moving structure 12 , and the volume of the second cavity 49 decreases, so that the gas in the second cavity 49 is discharged through the second one-way valve 44 ;

[0067] Step 4.4: The second one-way valve 44 is connected to the bellows 51, and the gas is discharged from the exhaust port 53 through the bellows 51. The gas discharged from the exhaust port 53 blows away the exhaust gas generated by the power pipe after docking to prevent it from obstructing the sight of the staff, so that the power pipe after hot melting is quickly cooled, condensed and fixed;

[0068] Step 4.5: At the same time, the volume of the first cavity 48 increases to form a pressure difference, so that the first cavity 48 sucks the gas in the telescopic airbag 33 into the first cavity 48 through the upper hose 35, and the telescopic airbag 33 contracts to release the power tube;

[0069] Step 4.6: After the telescopic airbag 33 loosens the power pipe, the staff removes the connected power pipe through the notch 32 on the clamping ring 31.

[0070] The beneficial effect of the present invention is that, compared with the prior art, the present invention places the power pipe inside the clamping structure, and uses the stand and the inflatable structure in coordination, so that when the power pipe is moved and docked through the stand, the volume of the first inner cavity and the second inner cavity inside the gas box changes, and then the telescopic airbag expands to clamp the power pipe. At the same time, after the telescopic airbag expands, the notch will shrink to prevent the power pipe from falling off from the inside of the clamping ring, so that the power pipe can be clamped in advance during the process of moving and docking the power pipe, and the power pipe is prevented from shaking or even falling off during the hot melting process, which saves labor costs, simplifies the operation steps, and improves the efficiency of docking the power pipe.

[0071] At the same time, the telescopic airbag adjusts the degree of clamping with the power pipe by inflating, expanding, exhausting and contracting. The telescopic airbag then adjusts the degree of inflation and deflation according to the power pipes of different radii, so that the clamping structure always clamps the power pipe, improving versatility. At the same time, the splint further improves the tightness and stability of the clamping structure 3 and the power pipe.

[0072] At the same time, the inflation structure and the exhaust structure of the present invention are used in conjunction with each other, so that when the device loosens the power pipe by moving the stand, the volumes of the first inner cavity and the second inner cavity inside the gas box also change, so that the gas in the second cavity is discharged from the exhaust port. The gas discharged from the exhaust port will disperse the exhaust gas generated by the power pipe after docking to prevent obstruction of the staff's line of sight, and the power pipe after hot melting will be quickly cooled, condensed and fixed, further improving the efficiency of power pipe docking.
