Description

Technical Field

[0001] The present invention relates to the technical field of concrete pipe production, and particularly to an automatic processing device for the outer edge of a concrete pipe. 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 rolling brush to brush. There are many tiny burrs on the outer edge surface of the pipe formed by this method, and it 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 is labor-consuming. In addition, the pipe is relatively high, and workers need to stand on a bracket to operate. At the same time, they also need 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 the products targeted by CN112170088A, CN103651010B, CN113973865B, etc. are different. Due to the large volume of concrete pipes and the need to smear cement as flat as possible, it is not easy to adopt methods such as spraying in the comparative documents. Therefore, at present, a special equipment for concrete pipes is needed. Therefore, in order to improve the processing efficiency and the forming quality of the pipes, there is an urgent need for a special equipment for processing the outer surface of concrete pipes.

Embodiment

[0020] The following further elaborates on the specific embodiments of the present invention in conjunction with the accompanying drawings.

[0021] Consisting of Figures 1 to 4 As shown, 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;

[0022] The support assembly 4 includes a support ring 401, which is installed via a plurality of support rods 2; a rotating ring 402 is sleeved inside the support rod 2, and a plurality of radial guide rods 403 are evenly distributed on the rotating ring 402. The guide rods 403 reciprocate axially and reset outward. A scraper 404 is installed at the inner end of each guide rod 403. After the rotating ring 402 rotates, the scraper 404 moves towards the center direction of the rotating ring 402;

[0023] When the support assembly 4 descends along the support rod 2, the rotating ring 402 does not rotate; when the support assembly 4 ascends along the support rod 2, the rotating ring 402 rotates;

[0024] A plurality of rotary brushes 5 capable of swinging towards the center of the support ring 401 are arranged on the support ring 401. A material box 6 is arranged above the rotary brushes 5, and a discharge port 9 corresponding to the rotary brushes 5 is arranged below the material box 6.

[0025] In order to make the scraping plate 404 move towards the center direction of the rotating ring 402 after the rotating ring 402 rotates, the guide rod 403 penetrates through the side wall of the rotating ring 402. There are two limit blocks 405, one on the left and one on the right, arranged on the guide rod 403, and a spring 406 is sleeved on the guide rod 403. A plurality of counterweight blocks 407 corresponding to the guide rod 403 one by one are installed on the rotating ring 402. Each counterweight block 407 is installed through a plurality of cross bars 408 penetrating the rotating ring 402. A limit protrusion 409 is arranged at the inner end of the cross bar 408, and a compression spring 410 is sleeved on the cross bar 408. A reversing wheel 411 corresponding to each counterweight block 407 is arranged on the rotating ring 402. A rope 412 is connected between the outer end of the counterweight block 407 and the outer end of the guide rod 403, and the middle part of the rope 412 is reversed by the reversing wheel 411.

[0026] In order to enable the support assembly 4 to move to directly above the concrete pipe to be processed, a semi-circular notch with an opening facing left is provided in the middle of the bracket 1.

[0027] In order to realize the installation of the rotary brush 5, a plurality of swing rods 7 are hinged on the support ring 401, a limit post 8 is arranged at the hinge point, the rotary brush 5 is installed on the swing rod 7, and the material box 6 is fixed on the swing rod 7.

[0028] In order to make the rotating ring 402 rotate when the support assembly 4 rises along the support rod 2, a platform 10 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 10, and there are two traveling gears 12 on the platform 10 that mesh with the rack surfaces of the guide rod 3. A motor and a vertical intermediate shaft 11 are arranged on the platform 10. The motor drives the intermediate shaft 11 to rotate. A toothed ring 14 is arranged on the outer edge surface of the rotating ring 402, and a one-way gear 13 for driving the toothed ring 14 is arranged on the intermediate shaft 11. The intermediate shaft 11 drives one of the traveling gears 12 to rotate through a gear set.

[0029] 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 directly above the concrete pipe. Since the middle area of the bracket 1 is set as a semi-circular notch, it is convenient to directly clamp on the outside of the concrete tank, and at the same time, it is also convenient for the positioning of the whole device.

[0030] At this time, the support assembly 4 will be directly above the concrete pipe. Then, the motor is started. Due to the design of the gear set, the motor drives the whole support assembly 4 to descend. Since the intermediate shaft 11 drives the toothed ring 14 through the one-way gear 13, the rotating ring 402 does not rotate when descending.

[0031] See Appendix Figure 2 and Appendix Figure 3, when the rotating ring 402 does not rotate, at this time, the guide rod 403 at the end of the scraping plate 404 will be reset outward under the action of the spring 406, and the counterweight 407 will be reset inward under the action of the compression spring 410 on the cross bar 408. At this time, the scraping plate 404 is in a state away from the concrete pipe.

[0032] Therefore, during the entire process of the support assembly 4 descending, the scraping plate 404 will not contact the concrete pipe, which can facilitate the entire support assembly 4 to quickly sleeved on the outside of the concrete pipe.

[0033] As the support assembly 4 descends, the rolling brush 5 at the end of the swing rod 7 above the support ring 401 will contact the concrete pipe. After contact, the swing rod 7 will be squeezed by the concrete pipe and swing upward by a certain angle, and finally the rolling brush 5 will contact the outer edge surface of the concrete pipe; at this time, the rolling brush 5 will roll along the outer edge surface of the concrete pipe, and there is a material box 6 above the rolling brush 5, and cement mortar is placed in the material box 6. Since the cement mortar for outer edge surface repair is relatively thin, it can flow freely, so it will flow onto the rolling brush 5 along the discharge port 9 of the material box 6. As the rolling brush 5 rolls, the cement mortar is smeared on the outer edge surface of the concrete pipe.

[0034] By evenly distributing multiple rolling brushes 5 in a circle, a larger range of smearing can be achieved.

[0035] 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 rolling brush 5 contacts the concrete pipe, so that the outer edge surface of the concrete pipe is smeared more evenly; then control the motor to reverse, so that the entire support assembly 4 rises, and at this time the rotating ring 402 will rotate.

[0036] After the rotating ring 402 rotates, under the action of centrifugal force, the counterweight 407 will move toward the outside, and then through the rope 412 and the reversing wheel 411, the guide rod 403 is pulled to move inward, that is, the guide rod 403 will drive the scraping plate 404 to move toward the outer edge surface of the concrete pipe, so that the scraping plate 404 presses on the outer edge surface of the concrete pipe; then as the rotating ring 402 rotates, multiple scraping plates 404 will level the outer edge surface of the concrete pipe.

[0037] Whether it is during the descending process or the ascending process, the rolling brush 5 can always smear the cement mortar on the outer edge surface of the concrete pipe, and then evenly spread it through the scraping plate 404. Multiple scraping plates 404 are in a spiral ascending state, and finally the uniform grinding of the entire outer edge surface of the concrete pipe is realized, with high efficiency and uniform smearing.

[0038] When the entire device moves to the top, it detaches from the concrete pipe; at this time, the rolling brush 5 loses support and stops rotating, and the cement mortar in the material box 6 no longer flows out; the entire device returns to the initial state.

[0039] This device is convenient to operate, without the need for manual climbing and rotating operations. By using the support component 4 to sleeve on the outer edge surface of the concrete pipe, the processing of the outer edge surface is carried out; it is fully automated, saving manpower and improving efficiency and quality.

[0040] In this device, the design of the scraping plate 404 is quite ingenious. By making the scraping plate 404 away from the concrete pipe during the descending process, it is convenient for the entire support component 4 to sleeve on the outside of the concrete pipe, preventing the scraping plate 404 from interfering. At the same time, it can also not apply during the descending process and only pre-add concrete; then during the ascending process, the scraping plate 404 starts to contact the concrete pipe. At this time, the rolling brush 5 has smeared more 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, avoiding missing areas.

[0041] By adjusting the rotation of the motor, the magnitude of the centrifugal force can be adjusted, and then the pressure of the scraping plate 404 pressing on the concrete pipe can be adjusted, so as to control the thickness of the concrete layer and achieve more diversified processing.

[0042] In this device, the 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.
