[0001] This utility model relates to a quick connection tool for ductile iron sewage pipes, belonging to the field of sewage pipe fitting technology. Background Technology

[0002] Ductile iron pipes have excellent structural strength, corrosion resistance, ductility, and easy installation. They are suitable for different geological conditions and corrosive soil environments, making them ideal pipes for urban water supply and gas transmission. They are also widely used in the field of sewage pipes.

[0003] Currently, in the installation and construction of municipal pipelines, the connection and installation of ductile iron sewage pipes are generally carried out manually step by step: one section of ductile iron sewage pipe is connected to another section by pulling or dragging, and sometimes by using tools such as hand winches. However, in the above-mentioned connection process, due to the long length and heavy weight of the sewage pipes, manual dragging is time-consuming and laborious. Even with auxiliary tools such as hand winches, workers still need to operate them, which cannot achieve the effect of rapid connection and reduce the labor intensity of workers. Therefore, there is an urgent need for a rapid connection tool for ductile iron sewage pipes to solve the above problems. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quick connection tool for ductile iron sewage pipes to solve the problems mentioned in the background. This utility model has a reasonable structure, which can not only help workers quickly connect ductile iron sewage pipes and improve work efficiency, but also reduce labor intensity to a certain extent.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick connection tool for ductile iron sewage pipes, comprising a ductile iron pipe body, a pipe connection expansion port, a connecting assembly, a fastening assembly, a nylon belt, a double sleeve, a take-up roller, a top support rod, and a transition bearing. The tail end of the ductile iron pipe body is provided with a pipe connection expansion port for connection. The connecting assembly is mounted on the outer surface of the middle section of the ductile iron pipe body, and the fastening assembly is installed at another pipe connection expansion port position on the ductile iron pipe body. The connecting assembly and the fastening assembly are connected by a nylon belt. The front end of the nylon belt has a double sleeve, which is fixed inside the fastening assembly. The tail end of the nylon belt is fixedly installed inside the take-up roller, and a top support rod is added to the top of the take-up roller. The top support rod and the bottom of the take-up roller are both equipped with transition bearings. The take-up roller is assembled with the connecting assembly. The connecting assembly includes an outer frame, an arc opening, a control switch, a side frame, a motor unit, inserting stakes, and rubber clamps. The top surface of the outer frame is equipped with a control switch, and side frames are connected to both sides of the outer frame. The bottom of the side frame is equipped with multiple inserting stakes, and a motor unit is installed between the multiple inserting stakes and at the bottom of the side frame. The multiple rubber clamps are fixedly installed at the arc opening position of the outer frame. The fastening assembly includes an upper clamp, a lower clamp, a clamping plate, a rubber layer, fastening bolts, and threaded sections. The upper and lower clamps are equipped with clamping plates on both sides, and the clamping plates have pre-drilled holes for easy installation of fastening bolts. The head of the fastening bolt is a threaded section.

[0006] Furthermore, a thick rubber layer is arranged on the inner surface of the upper and lower jackets, and the fastening bolts are equipped with matching nuts.

[0007] Furthermore, the included angle between the upper and lower jackets corresponds to the expansion port of the pipe connection.

[0008] Furthermore, the rubber in the plurality of rubber plates is the same as the rubber in the rubber layer.

[0009] Furthermore, the motor assembly includes a drive motor connected to the bottom of the take-up roller and a mobile power supply.

[0010] Furthermore, the motor units on both the left and right side frames are connected to the control switch via connecting wires.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a quick connection tool for ductile iron sewage pipes. Because it adds nylon belts, take-up rollers, motor units, rubber clamps, rubber layers, and fastening bolts, the rubber clamps and rubber layers further strengthen the fit of the connection and fastening components to the ductile iron pipe body, which helps to increase the friction during dragging. The motor unit drives the take-up rollers to wind up the nylon belt to connect the two sections of the ductile iron pipe body, which helps to improve work efficiency and reduce labor intensity.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4This utility model provides a technical solution: a quick connection tool for ductile iron sewage pipes, including a ductile iron pipe body 1, a pipe docking expansion port 2, a connecting component 3, a fastening component 4, a nylon belt 5, a double sleeve 6, a take-up roller 7, a top support rod 8, and a transition bearing 9. The ductile iron pipe body 1 has a pipe docking expansion port 2 at its tail for connection. The connecting component 3 is assembled on the outer surface of the middle section of the ductile iron pipe body 1, and the fastening component 4 is installed at another pipe docking expansion port 2 position on the ductile iron pipe body 1. The connecting component 3 and the fastening component 4 are connected by a nylon belt 5. The front end of the nylon belt 5 has a double sleeve 6, which is fixed inside the fastening component 4. The tail end of the nylon belt 5 is fixedly installed inside the take-up roller 7. A top support rod 8 is added to the top of the take-up roller 7, and both the top support rod 8 and the bottom of the take-up roller 7 have transition bearings. The bearing 9, the take-up roller 7, and the connecting assembly 3 are assembled together. The connecting assembly 3 includes an outer frame 31, an arc 32, a control switch 33, a side frame 34, a motor unit 35, a fixing stake 36, and a rubber clamp 37. The top surface of the outer frame 31 is provided with a control switch 33, and side frames 34 are connected to both the left and right sides of the outer frame 31. Multiple fixing stakes 36 are provided at the bottom of the side frame 34, and a motor unit 35 is installed between the multiple fixing stakes 36 and at the bottom of the side frame 34. Multiple rubber clamps 37 are fixedly installed at the arc 32 position of the outer frame 31. The fastening assembly 4 includes an upper clamp 41, a lower clamp 42, a clamping plate 43, a rubber layer 44, a fastening bolt 45, and a threaded section 46. The upper clamp 41 and the lower clamp 42 are provided with clamping plates 43 on both sides, and the clamping plates 43 have reserved holes for easy installation of the fastening bolts 45. The head of the fastening bolt 45 is a threaded section 46.

[0020] As the first embodiment of this utility model: the motor units 35 on both the left and right side frames 34 are connected to the control switch 33 via connecting wires, and the motor unit 35 includes a drive motor connected to the bottom of the winding roller 7 and a mobile power supply. This design, by setting the control switch 33, helps to simultaneously start the drive motors on the left and right side frames 34, thereby realizing the synchronous winding of the nylon belt 5 by the winding rollers 7 on both sides. The rubber in the multiple rubber clamps 37 is the same as the rubber in the rubber layer 44. This design further strengthens the fit of the ductile iron pipe body 1 through the rubber clamps 37, which helps to enhance the fit of the connecting assembly 3 to the ductile iron pipe body 1. The friction force, the included angle of the upper sleeve 41 and the lower sleeve 42 corresponds to the pipe connection expansion port 2. This design, by setting up a fastening component 4, uses the clamping between the upper sleeve 41 and the lower sleeve 42 to hold the pipe connection expansion port 2, which helps to connect the previous section of ductile iron pipe body 1 to the next section of ductile iron pipe body 1. A thick rubber layer 44 is arranged on the inner surface of the upper sleeve 41 and the lower sleeve 42, and the fastening bolt 45 is equipped with a matching nut. This design, with the help of the rubber layer 44, helps to enhance the friction force when the upper sleeve 41 and the lower sleeve 42 fit the pipe connection expansion port 2, and prevents them from falling off and loosening during the dragging process.

[0021] As a second embodiment of this utility model: When connecting and installing ductile iron sewage pipes, the worker first uses the external frame 31 on the connecting assembly 3 to press down one section of the ductile iron pipe body 1. The arc 32 on the external frame 31 engages with the ductile iron pipe body 1, and the side frames 34 on both sides can be stably installed using the ground-fixed stakes 36. Then, the upper sleeve 41 and lower sleeve 42 in the fastening assembly 4 are fixed and engaged with the pipe joint expansion port 2 of the previous section of the ductile iron pipe body 1 by connecting the fastening plate 43. Then, the fastening bolts 45 and their matching nuts are tightened. Before tightening the fastening bolts 45, the double sleeve 6 at the front end of the nylon strap 5 should be placed on the corresponding fastening bolts 45. In this way, the previous section of the ductile iron pipe body 1 and the next section of the ductile iron pipe body 1 are connected. The main body 1 is equipped with a pulling tool for connection. By starting the control switch 33, the motor group 35 on the bottom of the side frame 34 on both sides is powered, so that the internal drive motor rotor drives the winding roller 7 to rotate counterclockwise. Under the drive of the drive motor, the winding rollers 7 on both sides simultaneously wind up the nylon belt 5. The pipe docking expansion port 2 at the tail of the ductile iron pipe body 1, which is clamped with the fastening component 4, is pulled by the nylon belt 5, causing the previous section of ductile iron pipe body 1 to be dragged closer to the next section of ductile iron pipe body 1. After the pipe docking expansion port 2 is aligned and connected with the ductile iron pipe body 1, the winding of the winding roller 7 is turned off. In this way, the ductile iron sewage pipe is assembled and installed. When connecting the next section of pipe, the same operation can be performed by disassembling and installing the connecting component 3 and the fastening component 4 onto the next section of pipe.
