Description
Technical Field
[0001] This utility model relates to the field of cast iron pipe production technology, and in particular to an integrated cleaning, spraying and pipe pulling device for cast iron pipe production. Background Technology
[0002] In the production process of cast iron pipes, a centrifuge is used to cast the pipes. Before casting, the centrifuge mold needs to be cleaned. After cleaning, an anti-sticking coating is sprayed on the inner wall of the mold before casting. Finally, the formed cast iron pipe is pulled out of the centrifuge.
[0003] The production process of cast iron pipes is complex and requires a large number of auxiliary equipment. Each piece of equipment needs to be placed in the production environment, and each piece of equipment moves to the centrifuge in sequence when it is working.
[0004] In the current cast iron pipe production environment, cleaning, spraying, and pipe pulling are all done with separate equipment, which occupies a large space and has a complex track layout. Each piece of equipment is driven by a separate mobile motor, which is not conducive to control and management. Moreover, after the pipe pulling cart pulls out the cast iron pipe, it mainly relies on the clamping force of the pipe pulling pliers to support the cast iron pipe, which can easily cause the cast iron pipe to tip over, and the pipe pulling pliers are also prone to damage. Utility Model Content
[0005] This utility model mainly addresses the technical problems in the current cast iron pipe production environment, where cleaning, spraying, and pipe pulling are all done with separate equipment, which occupies a large space and has a complex track layout; each piece of equipment is driven by a separate moving motor, which is not conducive to control and management. The present invention proposes an integrated cleaning, spraying, and pipe pulling device for cast iron pipe production. The moving roller group is installed together with the cleaning device and the spraying device, and is uniformly controlled by a longitudinal moving motor to move longitudinally on a longitudinal track, which is easy to control and manage, and realizes the integration of cleaning, spraying, and pipe pulling.
[0006] This utility model provides an integrated cleaning, spraying, and pipe pulling device for cast iron pipe production, comprising: a longitudinal track, a moving roller group, a fixed roller group, a pipe pulling cart, a cleaning device, and a spraying device;

[0028] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.
[0029] like Figure 1-3 As shown in the figure, the present invention provides an integrated cleaning, spraying and pipe pulling equipment for cast iron pipe production, comprising: a longitudinal track 3, a moving roller group 5, a fixed roller group 6, a pipe pulling cart 7, a cleaning device 1 and a spraying device 2.
[0030] The longitudinal track 3 is arranged longitudinally in front of the centrifuge and is perpendicular to the length direction of the centrifuge. The position of the longitudinal track 3 corresponding to the tube mold of the centrifuge is the working position, and the corresponding equipment moves to the working position during operation.
[0031] The movable roller assembly 5, cleaning device 1, and spraying device 2 are movably mounted on the longitudinal track 3 and move along the longitudinal track 3; the movable roller assembly 5 is fixed together with the cleaning device 1 and the spraying device 2. Specifically, the movable roller assembly 5 is fixed together with the cleaning device 1 and the spraying device 2 by at least one connecting plate 11. A longitudinal moving motor 4 is installed on the movable roller assembly 5; the longitudinal moving motor 4 is connected to the traveling wheels of the movable roller assembly 5 via a transmission connection. Since the movable roller assembly 5 is fixed together with the cleaning device 1 and the spraying device 2, the three devices are driven by a single longitudinal moving motor 4, enabling movement along the longitudinal track 3, reducing the use of moving motors and making control more convenient. By using the three fixed devices, they move sequentially to the working position along the longitudinal track 3, simplifying the operation process and preventing interference between the devices.
[0032] The fixed roller group 6 is positioned at the end of the working position away from the centrifuge; the tube-pulling trolley 7 is movably positioned above the fixed roller group 6 along its length. A tube-pulling trolley traveling frame is provided above the fixed roller group 6 and the working position, and a tube-pulling trolley traveling track is arranged on the traveling frame. The tube-pulling trolley 7 can travel above the fixed roller group 6 and the working position, moving to the working position.
[0033] In this utility model, the track consists of only the longitudinal track 3 and the pipe pulling cart travel track. The pipe pulling cart travel track is also located above the fixed roller group 6. The track is simple to set up, occupies little space, and is easy to control.
[0034] The cleaning device 1 is equipped with a cleaning rod, and a cleaning brush is attached to the end of the cleaning rod. A lateral movement motor 8 is also installed on the cleaning device 1; the lateral movement motor 8 is driven by the cleaning rod via a sprocket and chain transmission mechanism. The lateral movement motor 8 can drive the cleaning rod and cleaning brush to extend and retract.
[0035] The spraying device 2 is equipped with a paint tank and a nozzle connected to the paint tank. The nozzle can be rod-shaped, and the nozzle is connected to the paint tank via a flexible hose. The paint tank provides the nozzle with anti-sticking paint. The spraying device 2 is equipped with a lateral movement motor 10; the lateral movement motor 10 is driven by the nozzle, which can be driven by a sprocket and chain transmission mechanism. The lateral movement motor 10 can drive the nozzle to extend and retract. In addition, an encoder 9 is installed on the lateral movement motor 10 to detect the forward distance of the spraying device 2, which facilitates setting the nozzle movement speed at different positions of the spraying device 2.
[0036] The pipe-pulling cart 7 is equipped with a pipe-pulling cylinder, and a pipe-pulling clamp is attached to the end of the telescopic rod of the pipe-pulling cylinder. When the telescopic rod of the pipe-pulling cylinder extends, it drives the pipe-pulling clamp to extend and open, clamping the inner wall of the cast iron pipe. This utility model provides the pipe-pulling cart 7 with a movable moving roller group 5 and a fixed, non-movable roller group 6; when the pipe-pulling cart 7 is pulling the pipe, the movable roller group 5 is in the working position (e.g., ...). Figure 3 As shown in the diagram, the cast iron pipe pulled out by the pipe pulling cart 7 can be lifted by the moving roller group 5 and the fixed roller group 6, which reduces the force on the pipe pulling pliers, makes the pipe pulling process stable, reduces the load on the equipment, and extends the service life of the equipment.
[0037] The working process of this utility model: The cleaning device 1 moves along the longitudinal track 3 to the working position (e.g., ... Figure 1 As shown, the moving roller group 5 and the spraying device 2 move together. The cleaning device's lateral movement motor 8 drives the cleaning rod and cleaning brush to extend and enter the centrifuge mold, cleaning the inner wall of the rotating mold. When the spraying device 2 moves along the longitudinal track 3 to the working position (e.g., ... Figure 2 As shown, the moving roller assembly 5 and the cleaning device 1 move together. The lateral movement motor 10 of the spraying device drives the nozzle to extend and enter the centrifuge mold, spraying the inner wall of the rotating mold. When the moving roller assembly 5 moves along the longitudinal track 3 to the working position (e.g., ... Figure 3 As shown, the spraying device 2 and the cleaning device 1 move together, and the pipe pulling cart 7 also moves to the working position (the pipe pulling cart 7 is located above the moving roller group 5). The pipe pulling cart 7 pulls the cast iron pipe out of the centrifuge, and the cast iron pipe will fall on the moving roller group 5 and the fixed roller group 6 until all the cast iron pipe is pulled out.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
