Description

Technical Field

[0001] This invention relates to the field of pipeline dismantling and assembly technology, and in particular to a special dismantling device for socket-type pipelines. Background Technology

[0002] Socket joints mainly include: lead alloy joints, asbestos cement joints, expandable filler joints, and rubber ring joints. Socket pipes are divided into rigid socket joints and flexible socket joints. A rigid socket joint involves inserting the pipe spigot into the pipe socket, aligning them, caulking with sealant, and then sealing with a sealing material to create a strong, closed system. A flexible socket joint involves placing an elastic rubber ring on the stop seal of the pipe socket, then applying force to insert the pipe spigot, forming a closed pipe that can adapt to displacement and vibration within a certain range.

[0003] In some special projects, such as urban land planning, it is necessary to dismantle existing socket-type pipes. However, there is a lack of auxiliary dismantling equipment, making dismantling inconvenient. In traditional dismantling, a crane is needed to lift the socket-type pipes. During the lifting process, changes in the angle of the pipes can easily damage the pipe openings, thereby reducing the secondary utilization rate of the pipes. Summary of the Invention

[0004] This invention discloses a special dismantling device for socket-type pipes, aiming to solve the technical problem in the background art where, in some special projects, such as urban land planning, it is necessary to dismantle existing socket-type pipes. However, during dismantling, there is a lack of auxiliary dismantling equipment, making dismantling inconvenient. Furthermore, in traditional dismantling, a crane is required to lift the socket-type pipes, and changes in the pipe angle during the lifting process can easily lead to damage to the pipe opening, thereby reducing the secondary utilization rate of the pipes.

[0005] This invention proposes a special dismantling device for socket-type pipes, comprising a pipe 1 and a winch body. One end of the pipe 1 is provided with a pipe 2. The winch body is located on one side of the pipe 2, and two connecting steel wires are provided on the winch body. One end of the two connecting steel wires is provided with a pipe pulling assembly. The pipe 1 and pipe 2 are provided with an external mounting shell, and the dismantling and breaking assembly is provided inside the mounting shell. Two fixing frames are fixedly connected to the outer wall of the mounting shell, and each of the two fixing frames is provided with a drive adjustment assembly.

[0006] The device is equipped with a connecting steel wire, a winch body, pipe one, pipe two, a dismantling and crushing component, a connecting pipe pulling component, and a drive adjustment component. The connecting pipe pulling component improves the coordination between the connecting steel wire and the winch body, enabling rapid extraction and recovery of dismantled pipes, thus increasing work efficiency. The dismantling and crushing component automatically crushes the cement mortar at the pipe joints, avoiding damage caused by angle adjustments and meeting recycling requirements. The drive adjustment component allows for real-time adjustment of the device's position based on the location of the pipe joints, enhancing the device's effectiveness.

[0007] In a preferred embodiment, the disassembly and crushing assembly includes a drive housing, the outer wall of which contacts the inner wall of a mounting housing. A gear ring is fixedly connected to the outer wall of the drive housing, and a mounting bracket is fixedly connected to the outer wall of the mounting housing. A motor is fixedly connected to one inner wall of the mounting bracket, and the output shaft of the motor is connected to a drive gear via a coupling. The drive gear meshes with the gear ring. Two mounting members are fixedly connected to the inner wall of the drive housing, and a shaft is movably connected to the inner wall of each mounting member. A gear is fixedly connected to one end of each shaft. The inner wall of one side of the drive housing is fixed... The device is connected to two motors (II). The output shafts of both motors (II) are connected to gears (II) via couplings. Gears (II) mesh with gears (II) respectively. Impact rods are fixedly connected to the outer walls of both shafts. Connecting members are fixedly connected to one side of the outer walls of both impact rods. Pressure spring rods are movably connected inside both connecting members. Fixing members are movably connected to one end of both pressure spring rods. Fixing members are fixedly connected to the inner wall of the drive housing on one side of their outer walls. Impact members are fixedly connected to one end of both impact rods. Multiple crushing pins are provided at equal intervals on the outer walls of both impact members.

[0008] By incorporating a disassembly and crushing component, the cement at the interface can be directly crushed, thereby reducing the connection between pipe one and pipe two and loosening it, facilitating rapid disassembly. Furthermore, during disassembly, the disassembly and crushing component does not require significant adjustment of the lifting angle of the socket-type pipe, thus avoiding damage to the pipe interface during disassembly and increasing the secondary utilization rate of the pipe after disassembly. The elimination of the need for lifting during disassembly reduces capital consumption.

[0009] In a preferred embodiment, the drive adjustment assembly includes fixed frames. One outer wall of each of the two fixed frames is fixedly connected to one inner wall of each of the two fixed brackets. Two mounting rods are fixedly connected inside each of the two fixed frames. Adjusting arms are movably connected to the outer walls of each of the four mounting rods, and movable wheels are movably connected inside each of the four adjusting arms. The outer walls of the four movable wheels contact the outer walls of pipe one and pipe two, respectively. A drive motor is fixedly connected to the top of each of the two adjusting arms. The output shafts of the two drive motors are fixedly connected to one outer wall of each of the two movable wheels via couplings. The outer walls of the four mounting rods are fitted with… The device is equipped with torsion springs. One end of each of the four torsion springs is fixedly connected to the inner wall of one side of each of the two fixed frames, and the other end of each of the four torsion springs is fixedly connected to the outer wall of one side of each of the four adjusting arms. Two mounting frames are fixedly connected to the outer wall of each of the two fixed frames. The inner wall of each of the two mounting frames on the same side is movably connected to the same winding component. Two connecting lines are fixedly connected to the outer wall of each of the two winding components. One end of each of the four connecting lines is fixedly connected to the outer wall of one side of each of the four adjusting arms. A winding motor is fixedly connected to the top of each of the two mounting frames. The output shafts of the two winding motors are fixedly connected to the top of each of the two winding components via couplings.

[0010] By incorporating a drive adjustment component, the device can move the mounting housing along the pipeline during use. This allows for real-time adjustment based on the location of the interface during disassembly. When the pipeline is long, it can be directly installed at the pipeline opening for convenient operation. This eliminates the need for workers to manually locate the interface cement position, improving work efficiency and reducing the workload of workers. Furthermore, the drive adjustment component can be adjusted according to the pipeline size during use, increasing the practicality of the device.

[0011] In a preferred embodiment, the connecting pipe assembly includes a first fastener, and one outer wall of the first fastener is fixedly connected to one end of one of the connecting wires; four adjusting screws are movably connected to the top of the first fastener, and the outer walls of the four adjusting screws are movably connected to the same second fastener, and one outer wall of the second fastener is fixedly connected to one end of another connecting wire; control knobs are fixedly connected to the top of each of the four adjusting screws, and multiple elastic plates are provided at equal intervals on one inner wall of both the first and second fasteners, and one outer wall of each of the multiple elastic plates is in contact with the outer wall of the second pipe.

[0012] By incorporating a connecting pipe-pulling assembly, the assembly secures the disassembled pipe during removal, facilitating separation and recovery by workers. This enhances the device's effectiveness and simplifies operation. Furthermore, the elastic plate prevents excessive tightening during installation, avoiding damage to the pipe and increasing the device's practicality. The assembly is also adjustable to accommodate different pipe sizes, further improving its applicability.

[0013] As can be seen from the above, the special dismantling equipment for socket-type pipes provided by the present invention has the function of assisting dismantling and avoiding damage. When dismantling the cement grouting interface of the pipe, it can break the cement and loosen it, avoiding damage to the pipe interface caused by traditional hoisting methods, thus improving the convenience of dismantling and the utilization rate of the pipe.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] The present invention discloses a special dismantling device for socket-type pipes, which is mainly used in scenarios where the pipe opening is easily damaged due to changes in pipe angle during dismantling, affecting the secondary utilization rate of the pipe.

[0024] Reference Figure 1-7 A special dismantling device for socket-type pipes includes a pipe 1 and a winch body 4. One end of the pipe 1 is provided with a pipe 2 3. The winch body 4 is located on one side of the pipe 2 3 and is provided with two connecting steel wires 10. One end of the two connecting steel wires 10 is provided with a pipe pulling assembly 5. The pipe 1 and the pipe 2 3 are provided with an installation housing 6. The installation housing 6 is provided with a dismantling and breaking assembly 9. Two fixing frames 8 are fixedly connected to the outer wall of the installation housing 6, and each of the two fixing frames 8 is provided with a drive adjustment assembly 2.

[0025] Specifically, the connecting pipe pulling assembly 5 can improve the coordination between the connecting steel wire 10 and the winch body 4 during use, thereby enabling the rapid pulling out and recycling of disassembled pipes to increase work efficiency; the disassembly and crushing assembly 9 can crush the cement slurry at the pipe interface during use, avoiding damage to the pipe caused by angle adjustment and meeting the recycling requirements; the drive adjustment assembly 2 can adjust the position of the device in real time according to the position of the pipe interface during use, increasing the effectiveness of the device.

[0026] Reference Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the disassembly and crushing assembly 9 includes a drive housing 901. The outer wall of the drive housing 901 contacts the inner wall of the mounting housing 6. A gear ring 903 is fixedly connected to the outer wall of the drive housing 901, and a mounting bracket 7 is fixedly connected to the outer wall of the mounting housing 6. A motor 904 is fixedly connected to one inner wall of the mounting bracket 7. The output shaft of the motor 904 is connected to a drive gear 905 via a coupling, and the drive gear 905 meshes with the gear ring 903. Two mounting members 906 are fixedly connected to the inner wall of the drive housing 901. The inner walls of both mounting members 906 are connected to shafts 907 via bearings. A gear 915 is fixedly connected to one end of each shaft 907. A gear 915 is fixedly connected to one inner wall of the drive housing 901. Two motors 914 are provided, and the output shafts of both motors 914 are connected to gears 913 via couplings. The gears 913 mesh with the gears 915 respectively. Impact rods 902 are fixedly connected to the outer walls of both shafts 907. Connecting parts 912 are fixedly connected to one side of the outer walls of both impact rods 902. Pressure spring rods 909 are connected to the inside of both connecting parts 912 via bearings. Fixing parts 908 are fixedly connected to one end of both pressure spring rods 909 via bearings. The outer walls of both fixing parts 908 are fixedly connected to the inner walls of the drive housing 901. Impact parts 911 are fixedly connected to one end of both impact rods 902. Multiple crushing pins 910 are provided at equal intervals on the outer walls of both impact parts 911.

[0027] Specifically, during the crushing of the cement grout at the pipe interface, drive motor 206-1 drives drive gear 905 to rotate via motor 904. Since drive gear 905 meshes with gear ring 903, it causes gear ring 903 and drive housing 901 to rotate. Simultaneously, motor 914 is activated, driving gear 913 to rotate. Since gear 913 meshes with gear 915, it causes gear 913 to rotate, which in turn drives shaft 907 to rotate. At this time, impact rod 902 rotates, compressing pressure spring rod 909. When gear 913 rotates to a certain position, it briefly separates from gear 915, releasing pressure from spring rod 909. This causes impact rod 902 to reverse direction, resulting in impact component 911 and crushing pin 910 crushing the cement grout at the pipe interface.

[0028] In specific application scenarios, the disassembly and crushing component 9 is suitable for the cement crushing process at the disassembly interface of socket-type pipes. That is, the disassembly and crushing component 9 can directly crush the cement at the interface, thereby reducing the connection effect between pipe 1 and pipe 3 and loosening it, so as to facilitate its quick disassembly. Moreover, during disassembly, the disassembly and crushing component 9 does not require a large adjustment of the hoisting angle of the socket-type pipe, thereby avoiding damage to the pipe interface during disassembly and increasing the secondary utilization rate of the pipe after disassembly.

[0029] It should be noted that the fact that disassembly does not require hoisting can reduce financial costs.

[0030] Reference Figure 1 , Figure 2 and Figure 5 In a preferred embodiment, the drive adjustment assembly 2 includes a fixed frame 201. One outer wall of each of the two fixed frames 201 is fixedly connected to one inner wall of each of the two fixed brackets 8. Two mounting rods 208 are fixedly connected inside each of the two fixed frames 201. Adjusting arms 204 are rotatably connected to the outer walls of each of the four mounting rods 208. Each of the four adjusting arms 204 has a movable wheel 205 connected to its interior via a bearing. The outer walls of the four movable wheels 205 are in contact with the outer walls of pipe 1 and pipe 2 3, respectively. A drive motor 206 is fixedly connected to the top of each of the two adjusting arms 204. The output shafts of the two drive motors 206 are fixedly connected to one outer wall of each of the two movable wheels 205 via couplings. The outer walls of the four mounting rods 208 are each fitted with... Four torsion springs 203 are provided. One end of each torsion spring 203 is fixedly connected to the inner wall of one side of each of the two fixed frames 201, and the other end of each torsion spring 203 is fixedly connected to the outer wall of one side of each of the four adjusting arms 204. Two mounting frames 202 are fixedly connected to the outer wall of one side of each of the two fixed frames 201. The inner wall of each of the two mounting frames 202 on the same side is connected to the same winding component 210 via bearings. Two connecting lines 207 are fixedly connected to the outer wall of each of the two winding components 210. One end of each of the four connecting lines 207 is fixedly connected to the outer wall of one side of each of the four adjusting arms 204. A winding motor 209 is fixedly connected to the top of each of the two mounting frames 202. The output shafts of the two winding motors 209 are fixedly connected to the top of each of the two winding components 210 via couplings.

[0031] Specifically, in use, the mounting housing 6 is installed outside the pipe. At this time, the winding motor 209 is started, which drives the winding component 210 to rotate, thereby winding the connecting wire 207. The connecting wire 207 then drives the adjusting arm 204 to rotate on the mounting rod 208. At this time, the adjusting arm 204 can drive the movable wheel 205 to contact the outer wall of the pipe. Simultaneously, the drive motor 206 is started, which drives the movable wheel 205 to rotate, thereby moving the device to the pipe interface for subsequent disassembly. After disassembly, the winding motor 209 rotates in the reverse direction. At this time, the connecting wire 207 is loosened, and the torsion spring 203 drives the adjusting arm 204 to reset, making it easy for the staff to remove the device.

[0032] In specific application scenarios, the drive adjustment component 2 is suitable for the disassembly position adjustment stage. That is, the drive adjustment component 2 can drive the mounting housing 6 to move on the pipeline during use, so that the device can be adjusted in real time according to the position of the interface during disassembly. When the pipeline is long, it can be directly installed at the pipeline opening, which is convenient for operation and use. There is no need for the staff to manually find the interface cement position, which improves work efficiency and reduces the workload of the staff. In addition, the drive adjustment component 2 can be adjusted according to the pipeline size during use, which increases the practicality of the device.

[0033] Reference Figure 1 , Figure 6 and Figure 7 In a preferred embodiment, the connecting pipe assembly 5 includes a fastener 501, and one outer wall of the fastener 501 is fixedly connected to one end of one of the connecting wires 10; four adjusting screws 503 are rotatably connected to the top of the fastener 501, and the outer walls of the four adjusting screws 503 are threadedly connected to the same fastener 505, and one outer wall of the fastener 505 is fixedly connected to one end of another connecting wire 10; a control knob 504 is fixedly connected to the top of each of the four adjusting screws 503, and multiple elastic plates 502 are provided at equal intervals on one inner wall of both the fastener 501 and the fastener 505, and one outer wall of each of the multiple elastic plates 502 is in contact with the outer wall of the pipe 3.

[0034] Specifically, during the pipe pulling and retrieval process, fastener 501 and fastener 505 are fitted onto the outer wall of the pipe. At this time, the operator rotates the control knob 504, which drives the adjusting screw 503 to rotate, thereby causing fastener 501 and fastener 505 to gradually approach each other until the elastic plate is in close contact with the outer wall of the pipe. At this time, the elastic plate 502 will deform, thus completing the fixing of fastener 501 and fastener 505. After the fixing is completed, the winch body 4 is started, and the connecting steel wire 10 is wound up by the winch body 4, thereby pulling out the pipe and completing the pipe disassembly.

[0035] In specific application scenarios, the connecting pipe pulling assembly 5 is suitable for the pipe disassembly and pulling process. That is, the connecting pipe pulling assembly 5 can fix the pipe to be disassembled during pipe disassembly, thereby facilitating the separation and recovery of the pipe by the staff, thus increasing the effectiveness of the device. It is also convenient and simple to operate. At the same time, when installing the connecting pipe pulling assembly 5, the elastic plate can prevent the pipe from being squeezed and damaged due to excessive tightness, which increases the practicality of the device. Furthermore, the connecting pipe pulling assembly 5 can be adjusted according to the pipe size, further improving the applicability of the device.

[0036] Working principle: In use, the mounting housing 6 is installed outside the pipe. The winding motor 209 is then started, driving the winding member 210 to rotate. This causes the winding member 210 to wind up the connecting wire 207, which in turn drives the adjusting arm 204 to rotate on the mounting rod 208. The adjusting arm 204 then drives the movable wheel 205 to contact the outer wall of the pipe. Simultaneously, the drive motor 206 is started, driving the movable wheel 205 to rotate, thus moving the device to the pipe interface for subsequent disassembly. When unloading and then crushing the cement grout at the interface, drive motor 206-1 drives drive gear 905 to rotate via motor 904. Since drive gear 905 meshes with gear ring 903, it causes gear ring 903 and drive housing 901 to rotate. Simultaneously, motor 914 is started, driving gear 913 to rotate. Since gear 913 meshes with gear 915, it causes gear 913 to rotate, which in turn drives shaft 907 to rotate. As the device rotates, the impact rod 902 rotates and compresses the pressure spring rod 909. When gear one 913 rotates to a certain position, it will briefly separate from gear two 915. At this time, the pressure spring rod 909 releases pressure, thereby driving the impact rod 902 in the opposite direction, which in turn causes the impact piece 911 and the crushing impact pin 910 to crush the cement plaster at the pipe interface. After disassembly, the winding motor 209 rotates in the opposite direction. At this time, the connecting wire 207 loosens, and the torsion spring 203 drives the adjusting arm 204 to reset, making it easier for the staff to remove the device. Then, the pipe is pulled out and retrieved. When fastener 501 and fastener 505 are fitted onto the outer wall of the pipe, the operator rotates the control knob 504, which in turn rotates the adjusting screw 503, causing fastener 501 and fastener 505 to gradually approach each other until the elastic plate is in close contact with the outer wall of the pipe. At this point, the elastic plate 502 will deform, thus fixing fastener 501 and fastener 505. After fixing, the winch body 4 is started to wind up the connecting steel wire 10, thereby pulling out the pipe and completing the pipe disassembly.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
