Description

Technical Field

[0001] The present invention relates to the technical field of concrete pipe production, and in particular to an automatic production equipment for concrete pipes. Background Art

[0002] Concrete pipes are pipes made of concrete or reinforced concrete and are used to transport fluids such as water, oil, and gas. Such pipes are equipped with longitudinal and circumferential prestressed steel bars, so they have high crack resistance and impermeability. At present, the commonly used forming methods are mainly radial extrusion forming, core mold vibration forming, etc. No matter which forming method, due to the non-uniform texture of concrete, problems such as air bubbles and adhesion during demolding, there will be many pits and unevenness on the outer surface of the formed concrete pipe. Therefore, it is necessary to repair and beautify the outer surface.

[0003] At present, the repair of the outer surface is generally carried out by workers holding a roller brush and brushing. There are many tiny burrs on the outer edge surface of the pipe formed by this method, which is not smooth enough. Another method is to smear the surface with concrete slurry manually. The outer surface of the pipe formed by this method is smooth, but it consumes a lot of manpower. In addition, the pipe is relatively high, and workers need to stand on a bracket to operate. At the same time, it is also necessary to rotate around the pipe for construction, and the construction difficulty is relatively large. For the equipment for smearing the outer edge surface, there are many related patents disclosed at present. For example, the application fields and targeted products of CN112170088A, CN103651010B, CN113973865B, etc. are different. Since the concrete pipe is large in volume and the cement smear should be as flat as possible, it is not easy to adopt methods such as spraying in the comparative documents. Therefore, there is a need for a special equipment for concrete pipes at present. Therefore, in order to improve the processing efficiency and the forming quality of the pipe, there is an urgent need for a special equipment for processing the outer surface of concrete pipes.

The scraper can swing and reset towards the center direction of the intermediate ring; when the rotating ring rotates clockwise, it can move the scraper in a direction away from the center of the intermediate ring.

[0007] When the support assembly descends along the support rods, the rotating ring rotates clockwise; when the support assembly ascends along the support rods, the rotating ring rotates counterclockwise.

Embodiment

[0018] The following further elaborates on the specific embodiments of the present invention with reference to the accompanying drawings.

[0019] Given by Figures 1 to 4 The present invention includes a support 1, on which a plurality of support rods 2 are fixed, and a support assembly 4 capable of moving up and down along the support rods 2 is installed on the plurality of support rods 2;

[0020] The support assembly 4 includes a support ring 401, which is installed via a plurality of support rods 2; there is a rotating ring 402 below the support rod 2, an intermediate ring 403 is arranged inside the support ring 401 and the rotating ring 402, and the intermediate ring 403 is rotatably connected to both the support ring 401 and the rotating ring 402; the rotation of the rotating ring 402 can drive the intermediate ring 403 to rotate; a plurality of support rods 404 are evenly distributed on the inner side surface of the intermediate ring 403, and a scraper 405 is hinged to the inner end of each support rod 404, and the scraper 405 can swing and reset towards the center direction of the intermediate ring 403; when the rotating ring 402 rotates clockwise, it can push the scraper 405 to move away from the center of the intermediate ring 403;

[0021] When the support assembly 4 descends along the support rod 2, the rotating ring 402 rotates clockwise; when the support assembly 4 ascends along the support rod 2, the rotating ring 402 rotates counterclockwise;

[0022] A plurality of rotary brushes 5 capable of swinging towards the center of the support ring 401 are arranged on the support ring 401, and a slurry supply pipe 6 is arranged above the rotary brushes 5.

[0023] In order to enable the support assembly 4 to move directly above the concrete pipe to be processed, a notch with an opening facing left is provided in the middle of the support 1.

[0024] In order to achieve the rotational connection of the intermediate ring 403 with both the support ring 401 and the rotating ring 402, the support ring 401 and the rotating ring 402 are arranged up and down without contact, annular grooves are formed on the inner edge surfaces of the support ring 401 and the rotating ring 402, and two upper and lower protruding rings are arranged on the outer edge surface of the intermediate ring 403, and the protruding rings are placed in the annular grooves.

[0025] In order to achieve the installation of the rotary brush 5 and the automatic opening and closing of the slurry supply pipeline 6, a plurality of swing rods 7 are hinged on the support ring 401. The rotary brush 5 is installed on the swing rod 7. An auxiliary rod 8 is arranged on the swing rod 7, and the outlet of the slurry supply pipeline 6 is fixed on the auxiliary rod 8. A feeding box 9 is arranged on the bracket 1, a pump 10 is arranged on the feeding box 9, and the lower end of the slurry supply pipeline 6 is connected to the outlet of the pump 10. A push-button switch 11 is arranged at the hinge point of the swing rod 7. After the swing rod 7 swings outwards, the push-button switch 11 is released and the pump 10 is powered on and started.

[0026] In order to achieve that when the rotating ring 402 rotates clockwise, it can push the scraper 405 to move away from the center of the middle ring 403, a ring-shaped disc 406 is fixed at the lower end of the rotating ring 402. A plurality of driving rods 407 corresponding to the scrapers 405 one by one are arranged on the ring-shaped disc 406. The driving rods 407 are located in the counterclockwise direction of the scrapers 405. A transverse stop rod 409 corresponding to the first rod is arranged on the middle ring 403. A torsion spring is arranged at the hinge point of the scraper 405 and the support rod 404, and a limit protrusion 408 located in the clockwise direction of the scraper 405 is arranged on the support rod 404.

[0027] In order to achieve that when the support assembly 4 descends along the support rod 2, the rotating ring 402 rotates clockwise, a platform is fixed on the support ring 401 on the right side. Among the plurality of support rods 2, the rightmost support rod 2 is a guide rod 3, and the left and right side surfaces of the guide rod 3 are rack surfaces. The guide rod 3 penetrates through the platform, and two left and right traveling gears 12 meshing with the rack surface of the guide rod 3 are arranged on the platform. A motor and a vertical intermediate shaft are arranged on the platform. The motor drives the intermediate shaft to rotate. A toothed ring 14 is arranged on the outer edge surface of the rotating ring 402, and a rotating gear 13 for driving the toothed ring 14 is arranged on the intermediate shaft. The intermediate shaft drives one of the traveling gears 12 to rotate through a gear set.

[0028] When using this device, first, the support assembly 4 needs to be moved to the uppermost end of the support rod 2 and driven by controlling the forward and reverse rotation of the motor. Then, the whole device is pushed to the directly above the concrete pipeline. In actual use, a semi-circular notch can be set in the middle area of the bracket 1, which is convenient for directly clamping on the outside of the concrete tank and can also facilitate the positioning of the whole device.

[0029] At this time, the support assembly 4 will be directly above the concrete pipe. Then start the motor to drive the whole support assembly 4 to descend. At the same time, due to the design of the gear set, the rotating ring 402 in the support assembly 4 can rotate clockwise.

[0030] See Appendix Figure 2 and Appendix Figure 3, when the rotating ring 402 rotates clockwise, first, the driving lever 407 on the annular disk 406 will rotate clockwise and drive the scraping plate 405 to swing. At this time, the scraping plate 405 will move away from the concrete pipe. Subsequently, after the scraping plate 405 swings through a certain angle, it will be blocked by the limiting protrusion 408 on the support rod 404. At this time, the scraping plate 405 stops swinging, and the driving lever 407 will drive the intermediate ring 403 to rotate together by driving the scraping plate 405. That is, the rotating ring 402 can drive multiple scraping plates 405 on the intermediate ring 403 to rotate together. However, before rotation, it will drive the scraping plate 405 to move away from the concrete pipe.

[0031] Therefore, during the entire process of the support assembly 4 descending, the scraping plate 405 will not contact the concrete pipe, which facilitates the entire support assembly 4 to quickly sleeved outside the concrete pipe.

[0032] Subsequently, when the support assembly 4 descends, the brush roller 5 at the end of the swing rod 7 above the support ring 401 will contact the concrete pipe. There is a torsion spring at the hinge point of the swing rod 7. Therefore, when the swing rod 7 is squeezed by the concrete pipe, it will swing upward by a certain angle, and finally the brush roller 5 will contact the outer edge surface of the concrete pipe. As the swing rod 7 swings through a certain angle, the button switch 11 installed at the hinge point of the swing rod 7 is released. At this time, the pump 10 is powered on and starts to work. The pump 10 transports the cement in the feeding tank 9 to above the multiple brush rollers 5 through the slurry supply pipe 6. As the brush roller 5 rolls on the outer edge surface of the concrete pipe, the cement is smeared on the outer edge surface of the concrete pipe.

[0033] Until it descends to the bottom; at this time, the bracket 1 can be rotated by a certain angle to change the area where the brush roller 5 contacts the concrete pipe, so that the outer edge surface of the concrete pipe is smeared more evenly. Subsequently, control the motor to reverse to make the entire support assembly 4 rise. At this time, the rotating ring 402 will rotate counterclockwise.

[0034] When the rotating ring 402 rotates counterclockwise, the driving lever 407 no longer drives the scraping plate 405. The scraping plate 405 will reset towards the outer edge surface of the concrete pipe under the action of the torsion spring, so that the scraping plate 405 presses on the outer edge surface of the concrete pipe. Subsequently, the driving lever 407 will drive the entire intermediate ring 403 to rotate through the stop lever 409.

[0035] Whether it is during the descending process or the ascending process, the slurry supply pipe 6 will always supply cement. Therefore, during the ascending process, through the rotation of the multiple scraping plates 405, the cement smeared on the outer edge surface of the concrete pipe by the brush roller 5 can be evenly spread out and in a spiral ascending state, realizing the uniform grinding of the entire outer edge surface of the concrete pipe, with high efficiency and uniform smearing.

[0036] After the entire device moves to the uppermost position, it disengages from the concrete pipe; at this time, the roller brush 5 loses support, the swing rod 7 resets, and the push button switch 11 is pressed to notify the pump 10 to work, achieving the automatic closing of the slurry supply pipeline 6. The entire device returns to its initial state.

[0037] This device is convenient to operate and does not require manual climbing and rotating operations. It uses the support component 4 to sleeve on the outer edge surface of the concrete pipe to process the outer edge surface; it is fully automated, saving manpower and improving efficiency and quality.

[0038] In this device, the design of the scraper 405 is quite ingenious. By making the scraper 405 move away from the concrete pipe during the descent, it is convenient for the entire support component 4 to sleeve on the outside of the concrete pipe to prevent the scraper 405 from interfering. At the same time, it can also not apply during the descent and only pre-add concrete; then during the ascent, the scraper 405 starts to contact the concrete pipe. At this time, the roller brush 5 has smeared a lot of cement on the outer edge surface of the concrete pipe. Scraping at this time can ensure that the entire outer edge surface of the concrete pipe can be evenly smeared and avoid missing areas.

[0039] In this device, multiple swing rods 7 can play a positioning role on the one hand, and on the other hand, through the swing change of the swing rods 7, the automatic opening and closing of the feeding are realized, simplifying the operation process.

[0040] In this device, the scraper 405 has a certain swing angle, and at the same time, the swing rod 7 also has a certain swing angle, which can adapt to various types of pipes with different diameters within a certain range.
