Description

Technical Field

[0001] The invention relates to the technical field of reinforced concrete drainage pipe production, in particular to a pipe turning device for producing reinforced concrete drainage pipes. Background Art

[0002] Cement pipes are also called cement pressure pipes and reinforced concrete pipes. They can be used as drainage pipes in urban construction and foundations, and can be used to drain sewage, flood control and drainage, as well as water pipes and farmland wells used in some special factories and mines. They are generally divided into: flat reinforced concrete cement pipes, flexible tongue and groove reinforced concrete cement pipes, socket reinforced concrete cement pipes, F-type steel socket cement pipes, flat sleeve interface cement pipes, tongue and groove cement pipes, etc. Reinforced concrete drainage pipes are suitable for industrial and residential construction and other fields. They are used for sewer systems and building drainage. Their diameters can be customized. They have the advantages of high strength and good durability. They are widely used in underground engineering and tunnel construction. When using them, you need to choose the right products and ensure correct installation and maintenance. Reinforced concrete drainage pipes are a pipe material with a wide range of applications. They can be widely used in the following occasions: internal and external drainage systems, rainwater systems, ventilation systems, fire protection systems, etc. of various buildings, drainage systems, sewage treatment systems, rainwater collection and utilization systems of municipal engineering, various discharge systems in industrial parks, chemical industry wastewater treatment systems, etc., and drainage systems in transportation places such as roads, railways, airports, and docks.

[0003] When the existing pipe turning device is in use, such as application number CN202320048738.X, a pipe turning device for the production of reinforced concrete drainage pipes is provided, including a base, the upper surface of the base is fixedly connected to a first vertical plate, one side of the first vertical plate is fixedly connected to a first drive motor, one end of the first drive motor is fixedly connected to a first fixed sleeve, and a clamping mechanism is provided on one side of the first fixed sleeve. The pipe-turning device for producing reinforced concrete drainage pipes is provided with fixing bolts, a support shaft, a first threaded hole, a second threaded hole, a clamping bolt, a spring and a rubber block. First, the corresponding support shaft is selected according to the inner diameter of the reinforced concrete drainage pipe to be processed, and the support shaft and the first fixing sleeve are threadedly connected through the second threaded hole by using the fixing bolt, and then the clamping bolt is screwed into the second threaded hole. At this time, the spring can prevent the clamping bolt from damaging the surface of the reinforced concrete drainage pipe, and the friction force of the rubber block is relatively large, which can make the fixation of the reinforced concrete drainage pipe more stable. However, in the above technology, the pipe fixed by the clamping mechanism needs to be manually adjusted in time, which increases the burden on users and reduces the automated processing efficiency of the equipment.

[0040] In an embodiment of the present invention, when rolling operation is required, the rolling motor 404 at one end of the motor base 403 on the notch plate 402 is used to output power to drive the output end to operate, so that the rolling motor 404 drives the notch base 408 at one end of the toothed rod 405 to rotate, so that the drain pipe body 5 is rotated to a suitable position. When positioning is required, the pneumatic telescopic rod 407 is used to output power to drive the output end to perform telescopic operation, so that the rack 406 is plugged into the toothed rod 405 for positioning, which is convenient for users to perform effective processing operations.

[0041] A toothed rod 405 is provided at the output end of the rolling motor 404, and a rack 406 is provided on the side of the toothed rod 405, a pneumatic telescopic rod 407 is provided on the outer side of the rack 406, a notch base 408 is provided at the inner end of the toothed rod 405, a cylinder 409 is provided on the inner side of the notch base 408, and a fixed patch 4010 is provided at the output end of the cylinder 409.

[0042] In an embodiment of the present invention, when initial positioning is required, the cylinder 409 on the notch base 408 is used to output power to drive the output end to operate, so that after the cylinder 409 outputs power to extend and retract, the fixing patch 4010 is attached to the upper drainage pipe body 5.

[0045] The working principle of the present invention is as follows: when in use, the bottom block 101 is used to place the equipment at the processing site. After the installation is completed, the shock absorber 102 supports the bolt steel pad 103 effectively. After the support, the shock absorption effect can be effectively achieved when the material is loaded and unloaded, thereby reducing the damage to the equipment. When processing is required, the electric rotating seat 104 is used to output power to drive the output end to operate so that the assembly plate 105 drives the rotating platform 106 to rotate and reach a suitable angle position. When the rotating platform 106 rotates and reaches a suitable angle position, the hydraulic cylinder 108 on the inner side of the end of the extension sleeve 107 outputs power to drive the output end to operate. The output end of the device is operated. When the hydraulic cylinder 108 outputs power to extend and retract, the push frame 109 pushes the flip shock absorbing component 2 to a suitable height position. When the flip shock absorbing component 2 reaches a suitable height position, the assembly base 209 on the inner side of the two ends of the rotating frame 208 is used to bolt the expansion and contraction adjustment component 3. Since the damper 2010 is installed, the vibration of the equipment can be effectively reduced to improve the service life of the equipment. When flipping is required, the rotating motor 207 is used to output power to drive the output end to operate. After the rotating motor 207 outputs power, the meshing gear set 206 is meshed and driven. The meshing transmission operation of the group 206 can drive the transmission shaft 204 on the inner side of the damping bearing seat 203 to drive the expansion and contraction adjustment component 3 to flip. When the initial positioning is required, the cylinder 409 on the notch base 408 is used to output power to drive the output end to operate, so that the cylinder 409 outputs power to stretch and operate so that the fixed patch 4010 fits the upper drainage pipe body 5. After the fixed patch 4010 fits the upper drainage pipe body 5, the positioning effect is achieved. After the fixed patch 4010 positions the upper drainage pipe body 5, the hydraulic telescopic rod 4013 on the inner side of the double ring shell 4012 is used to output power to drive the output end to operate, so that the hydraulic extension The output power of the retracting rod 4013 drives the arc-shaped clamping block 4014 to further clamp and position the drain pipe body 5. When rolling operation is required, the rolling motor 404 at one end of the motor base 403 on the notch plate 402 is used to output power to drive the output end to operate, so that the rolling motor 404 drives the notch base 408 at one end of the toothed rod 405 to rotate, so that the drain pipe body 5 is rotated to a suitable position. When positioning is required, the pneumatic telescopic rod 407 is used to output power to drive the output end to telescope and operate, so that the rack 406 is plugged into the toothed rod 405 for positioning, which is convenient for users to perform effective processing operations.
