Description

Technical Field

[0001] The present invention relates to a municipal pipeline construction device, and particularly to a hot melt butt welding device for municipal sewage drainage pipes. Background Art

[0002] The existing hot melt butt welding of municipal sewage drainage pipes is mainly carried out by manual pushing. During the operation, workers use a professional hot melt machine to heat the pipes to a molten state. Then, they closely align the two pipes to be butted and use manual thrust to push them together. In this way, the ends of the two pipes can be tightly combined in the hot melt state to form a continuous pipe.

[0003] Although the manual pushing butt welding method is effective, it also has some limitations. First of all, it has high requirements for the skills and experience of workers, and they need to be able to accurately control the temperature of the hot melt machine and the thrust during butt welding. Secondly, due to manual operation, the butt welding accuracy and efficiency may be affected to a certain extent. In addition, in large or complex projects, more workers and longer time may be required to complete the butt welding work.

[0004] In order to improve efficiency and accuracy, some researchers are exploring the application of automation and robot technology in the hot melt butt welding of municipal sewage drainage pipes. Therefore, the present invention aims to design an accurately guided hot melt butt welding device for municipal pipelines. Summary of the Invention

[0005] In order to overcome the disadvantages that it is difficult to control the butt welding force by manual sewage pipe butt welding, and the butt welding accuracy and efficiency are relatively low, the present invention provides an accurately guided hot melt butt welding device for municipal sewage drainage pipes.

[0006] A hot melt butt welding device for municipal sewage drainage pipes includes a main body bracket, moving wheels, a sliding rod and a hot melt machine. Moving wheels are arranged at the bottom of the main body bracket, a horizontal sliding rod is fixedly connected to the middle of the main body bracket, the hot melt machine is slidably connected to the sliding rod, and the hot melt machine slides towards each other to close, and then hot melt welding is carried out on the drainage pipe. It also includes a first slide rail, a second slide rail, a moving rod, a sleeve and a guide rod. The first slide rail is fixedly connected to the main body bracket, the second slide rails are symmetrically arranged and fixedly connected to both ends of the first slide rail, symmetric sliding grooves are opened on the second slide rails, the moving rod is slidably connected in the sliding grooves, the upper end of the moving rod slidably penetrates through the guide rod for sliding limit, the lower end of the moving rod is slidably connected to the sleeve, the sleeve is semicircular and a rubber strip is arranged on the inner side surface, a first return spring is connected between the sleeve and the moving rod. The end parts of the two sections of drainage pipes are respectively placed into the sleeves at both ends, and the sleeves move towards each other under the action of the first return spring to clamp and fix the drainage pipes. The moving rods are slid towards each other, and the front and rear sleeves butt the drainage pipes and the butt welding point is located inside the hot melt machine. Turning on the hot melt machine can carry out hot melt welding on the two sections of drainage pipes.

[0007] As a further preferred solution, it further includes a supporting block, a connecting rod, a pull rod, a first wedge block and a second wedge block. The end of the first slide rail extends with a limiting plate. The connecting rod is slidably limited within the limiting plate. A supporting block is fixedly connected to the end of the connecting rod. The supporting block can contact and support the guiding rod. The pull rod is slidably connected to the supporting block and a second return spring is connected between the two. A first wedge block is fixedly connected to the bottom of the pull rod. A second wedge block is fixedly connected to the back surface of the hot melt machine. The first wedge block can contact and horizontally push the second wedge block. The inclined surface of the first wedge block is located at the upper part, and the inclined surface of the second wedge block is located at the lower part.

[0008] As a further preferred solution, it further includes a servo motor, a lead screw, a hinge block and a two-link rod. The servo motor is fixed to the bottom of the first slide rail by bolts. The output shaft of the servo motor is threadedly connected with the lead screw. The hinge blocks are symmetrically arranged and threadedly connected to the lead screw. The middle of the two-link rod is rotatably connected to the hinge block, and the end of the two-link rod is rotatably connected to the moving rod.

[0009] As a further preferred solution, symmetric threads are provided on the lead screw. When the servo motor is started to drive the lead screw to rotate, the lead screw can drive the hinge blocks to move towards or away from each other. When the hinge blocks move towards each other, the hinge blocks pull the moving rod to slide towards each other through the two-link rod, so as to achieve the effect of moving the drain pipe in the sleeve closer to the hot melt machine. When the hinge blocks move away from each other, the hinge blocks push the moving rod to slide away from each other through the two-link rod, and the front and rear sleeves thus move away from each other.

[0010] As a further preferred solution, it further includes a supporting bracket. The supporting bracket is slidably connected to the middle of the main body bracket. The supporting bracket is provided with a limiting groove. The supporting bracket supports and fixes the connecting rod through the limiting groove.

[0011] As a further preferred solution, it further includes a support frame, a tapered block and a cylinder. The lower part of the main body bracket is symmetrically provided with sliding support frames. The tapered blocks are arranged oppositely and slidably connected within the support frames. The cylinder is fixedly connected to the support frame. The telescopic end of the cylinder is connected to the tapered block. When the drain pipe is placed on the ground, the support frame is moved downward until the tapered block contacts the ground, and then the cylinder is started to push the tapered block to move. The tapered block can lift the drain pipe upward, and then the sleeve clamps and fixes the drain pipe.

[0012] As a further preferred solution, it further includes a fixing pin. The fixing pin is slidably inserted through the main body bracket and the support frame. The fixing pin can limit and fix the support frame. When the support frame slides downward to the limit, the tapered block contacts the ground, and when the support frame slides upward to the limit, the fixing pin can be used for fixing.

[0013] As a further preferred solution, it further includes a fan. The fan is connected to the main body bracket and the fan points to the hot melt machine.

[0014] The present invention has the following advantages: 1. The sleeve clamps and fixes the ends of the two drain pipes, and then the servo motor is started to drive the screw rod to rotate. The screw rod can drive the hinge block to move towards each other. The hinge block pulls the moving rod to slide towards each other through the two-link rod. Under the guidance of the second slide rail, the moving rod accurately docks the drain pipes, achieving the effect of accurately hot-melting and docking the drain pipes in the sleeve by the hot-melting machine.

[0015] 2. Move the connecting rod upward. The connecting rod drives the supporting block to move synchronously. The supporting block drives the sleeve to move upward through the guiding rod, so that the sleeve moves to the height of the hot-melting machine. At the same time, the supporting block pulls the pull rod and then drives the first wedge block to move upward. The first wedge block pushes the second wedge block to move towards each other, thereby pushing the hot-melting machine to close for hot-melting welding, achieving the effect of automatically closing the hot-melting machine during the docking of the drain pipes.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0026] Embodiment: A hot melt butt joint device for municipal sewage drain pipes, as Figures 1-3 shown, includes a main body bracket 1, moving wheels 101, a sliding rod 2, and a hot melt machine 3. Moving wheels 101 are arranged at the bottom of the main body bracket 1, which is convenient for transporting the device. A horizontal sliding rod 2 is fixedly connected to the middle of the main body bracket 1. The hot melt machine 3 is slidably connected to the sliding rod 2, and the hot melt machine 3 slides towards each other to close, and then the drain pipes are hot melt welded. It also includes a first slide rail 4, a second slide rail 5, a moving rod 6, a sleeve 7, and a guide rod 9. The first slide rail 4 is fixedly connected to the top of the main body bracket 1. The second slide rails 5 are symmetrically arranged and fixedly connected to both ends of the first slide rail 4. Symmetrical chutes are opened on the second slide rails 5. The moving rod 6 is slidably connected in the chutes. The upper end of the moving rod 6 is slidably penetrated by the guide rod 9 for sliding limit. The lower end of the moving rod 6 is slidably connected to the sleeve 7. The sleeve 7 is semicircular and a rubber strip is arranged on the inner side. A first return spring 8 is connected between the sleeve 7 and the moving rod 6. The end parts of the two drain pipes are respectively placed into the sleeves 7 at both ends. The sleeves 7 move towards each other under the action of the first return spring 8 to clamp and fix the drain pipes. The moving rods 6 are slid towards each other, and the front and rear sleeves 7 butt joint the drain pipes and the butt joint point is located in the hot melt machine 3. Turning on the hot melt machine 3 can hot melt weld the two drain pipes.

[0027] As Figure 1 and Figure 4As shown, it further includes a supporting block 10, a connecting rod 1001, a pull rod 11, a first wedge block 13 and a second wedge block 14. The end of the first slide rail 4 extends with a limiting plate. The connecting rod 1001 is slidably limited within the limiting plate. The end of the connecting rod 1001 is fixedly connected with the supporting block 10. The supporting block 10 can contact and support the guide rod 9. The pull rod 11 is slidably connected to the supporting block 10 and a second return spring 12 is connected between them. The bottom of the pull rod 11 is fixedly connected with the first wedge block 13. The back surface of the hot melt machine 3 is fixedly connected with the second wedge block 14. The first wedge block 13 can contact and horizontally push the second wedge block 14. The inclined surface of the first wedge block 13 is located at the upper part, and the inclined surface of the second wedge block 14 is located at the lower part. Therefore, moving the first wedge block 13 upward can push the second wedge block 14 to move horizontally (specifically, reference can be made to Figure 4 ). After the sleeve 7 clamps and fixes the drain pipe, move the connecting rod 1001 upward. The connecting rod 1001 drives the supporting block 10 to move synchronously. The supporting block 10 drives the sleeve 7 to move upward through the guide rod 9, so that the sleeve 7 moves to the height of the hot melt machine 3. At this time, horizontally push the moving rod 6 so that the drain pipe in the sleeve 7 enters the hot melt machine 3. At the same time, the supporting block 10 pulls the pull rod 11 and then drives the first wedge block 13 to move upward. The first wedge block 13 pushes the second wedge block 14 to move in the opposite direction, so as to push the hot melt machine 3 to close for hot melt welding.

[0028] As Figure 1 and Figure 5 shown, it further includes a servo motor 15, a lead screw 16, a hinge block 17 and a two-link 18. The servo motor 15 is fixed to the bottom of the first slide rail 4 by bolts. The output shaft of the servo motor 15 is threadedly connected with the lead screw 16. The hinge blocks 17 are symmetrically arranged and threadedly connected to the lead screw 16. The middle of the two-link 18 is rotatably connected to the hinge block 17. The end of the two-link 18 is rotatably connected to the moving rod 6. Symmetrical threads are provided on the lead screw 16. Starting the servo motor 15 drives the lead screw 16 to rotate. The lead screw 16 can drive the hinge blocks 17 to move towards or away from each other. When the hinge blocks 17 move towards each other, the hinge blocks 17 pull the moving rod 6 to slide towards each other through the two-link 18, so as to achieve the effect of approaching the drain pipe in the sleeve 7 to the hot melt machine 3. When the hinge blocks 17 move away from each other, the hinge blocks 17 push the moving rod 6 to slide away from each other through the two-link 18, and the front and rear sleeves 7 are thus separated from each other.

[0029] As Figure 1 and Figure 6 shown, it further includes a supporting bracket 19. The supporting bracket 19 is slidably connected to the middle of the main body bracket 1. The supporting bracket 19 is provided with a limiting groove. The supporting bracket 19 supports and fixes the connecting rod 1001 through the limiting groove.

[0030] As Figure 1 and Figure 7As shown, it further includes a support frame 20, a conical block 21 and a cylinder 22. The lower part of the main body support 1 is symmetrically provided with slidable support frames 20. The conical blocks 21 are arranged oppositely and slidably connected within the support frames 20. The cylinder 22 is fixedly connected to the support frame 20, and the telescopic end of the cylinder 22 is connected to the conical block 21. When the drain pipe is placed on the ground, the support frame 20 is moved downward until the conical block 21 contacts the ground, and then the cylinder 22 is activated to push the conical block 21 to move. The conical block 21 can lift the drain pipe upward, and then the drain pipe is clamped and fixed by the sleeve 7.

[0031] As Figure 7 shown, it further includes a fixing pin 23. The fixing pin 23 is slidably inserted through the main body support 1 and the support frame 20. The fixing pin 23 can limit and fix the support frame 20. When the support frame 20 slides downward to the limit, the conical block 21 contacts the ground, and when the support frame 20 slides upward to the limit, the fixing pin 23 can be used for fixing.

[0032] As Figure 1 and Figure 8 shown, it further includes a fan 24. The fan 24 is connected to the main body support 1 and points to the hot melt machine 3, aiming to quickly cool and shape the drain pipe after hot melt butt joint.

[0033] The technical principles of the embodiments of the present invention have been described above in combination with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be construed in any way as a limitation on the protection scope of the embodiments of the present invention. Based on the explanations herein, those skilled in the art can readily conceive of other specific embodiments of the embodiments of the present invention without creative efforts, and these embodiments will fall within the protection scope of the embodiments of the present invention.
