Description

Technical Field

[0001] The present invention relates to the technical field of pile driving, and in particular to an automatic painting device for a pile driver. Background Art

[0002] As society's demand for electricity increases, the energy structure needs to be optimized, which requires the construction of more photovoltaic power stations. To protect arable land, photovoltaic power stations are often built at sea or in deserts with strong winds. In such windy environments, the stability of photovoltaic panels depends on stable photovoltaic pile foundations. During the construction of the pile foundations, the top of the pile foundations needs to be painted for corrosion protection. At present, the painting process of photovoltaic is mainly to manually apply anti-corrosion paint on the top of the cement pile after the pile driver presses the cement pile into the pit, such as Figure 1 As shown, however, during the painting process of the photovoltaic pile foundation, a pile driver is required to provide auxiliary support for the pile foundation, and then the staff surrounds the cement pile to paint it. This process is very troublesome to operate, and the painting efficiency is low. Moreover, since the cement pile is not completely fixed, it may fall over during painting, which poses a certain safety risk. In view of this, the present invention proposes an automatic painting device for pile driving with a pile driver. Summary of the Invention

DETAILED DESCRIPTION

[0019] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0020] like Figures 2 to 8 As shown, this embodiment proposes an automatic painting device for pile driving by a pile driver, including a pile driving machine body 1, a fixing frame 2 is fixedly connected to the top of the cab of the pile driving machine body 1, a hydraulic rod 3 is fixedly connected to one side of the fixing frame 2, the output end of the hydraulic rod 3 is fixedly connected to the mounting frame 5, and a painting mechanism 4 is provided on the mounting frame 5, and the painting mechanism 4 includes a motor 41, the motor 41 is fixedly mounted on the top of the mounting frame 5, one end of the inner side of the mounting frame 5 is rotatably connected to a vertically arranged rotating shaft 42, the top end of the rotating shaft 42 is fixedly connected to the output shaft of the motor 41, and the other end of the inner side of the mounting frame 5 is rotatably connected to a screw rod 43 arranged parallel to the rotating shaft 42, and a threaded connection is provided on the screw rod 43. It is connected to a movable seat 44, one end of which is slidably connected to the rotating shaft 42, and the other end of the movable seat 44 is fixedly connected to an arc plate 45, and a guide groove 451 is provided at the bottom end of the arc plate 45. The guide groove 451 is an arc structure, and the curvature of the guide groove 451 is 180 degrees. A painting component 46 is provided on the inner side of the guide groove 451 for sliding to paint the outer wall of the cement pile 6. The top end of the fixed frame 2 is provided with a transmission member 47 that drives the screw rod 43 to rotate intermittently by cooperating with the rotation of the rotating shaft 42, and the bottom end of the fixed frame 2 is provided with a linkage member 48 that drives the painting component 46 to slide back and forth along the guide groove 451 by cooperating with the rotation of the rotating shaft 42.

[0021] The cement pile 6 is pressed by the pile driving machine body 1 and the cement pile 6 is kept stable. Then, the hydraulic rod 3 is controlled to make the mounting frame 5 approach the cement pile 6, which causes the curved plate 45 to move to the outer edge of the cement pile 6, so that the painting component 46 contacts the cement pile 6. Then, the motor 41 is started to drive the rotating shaft 42 to rotate, which causes the linkage 48 to drive the painting component 46 to slide back and forth along the guide groove 451, so that the painting component 46 paints the outer wall of the cement pile 6. At the same time, the transmission member 47 drives the screw rod 43 to rotate intermittently, so that the movable seat 44 can intermittently translate upward, which causes the curved plate 45 to follow the movable seat 4 4 intermittently translates upward, so that the painting assembly 46 can paint the outer wall of the cement pile 6 in the vertical direction. Since the curvature of the guide groove 451 is 180 degrees, the painting assembly 46 can paint half of the surface of the cement pile 6. When half of the outer wall of the cement pile 6 is painted, the position of the cab of the pile driving machine body 1 is adjusted to allow the painting assembly 46 to paint the other half of the outer wall of the cement pile 6, thereby achieving full painting of the outer wall of the cement pile 6. The entire process only requires the driver of the pile driving machine body 1 to operate alone to achieve automatic painting of the cement pile 6, which not only improves the painting efficiency but also reduces safety risks.

[0022] Furthermore, a paint storage box 49 for storing anti-corrosion paint is fixedly connected to the outer side of the fixing frame 2, and a paint supply component 40 is provided on the outer side of the mounting frame 5 for supplying paint liquid to the painting component 46 by cooperating with the rotation of the rotating shaft 42. The painting component 46 includes a movable tube 461, which passes through the arc plate 45 and is slidably connected to the inner wall of the guide groove 451. The middle part of the movable tube 461 is fixedly connected to two parallel limit rings 462, which respectively conflict with the inner wall and outer wall of the arc plate 45. One end of the movable tube 461 is provided with a paint brush. Part 463, the other end of the movable tube 461 is fixedly connected to a paint guide hose 464 communicated with the interior of the movable tube 461, the paint brush part 463 includes an arc seat 4631, the outer wall of the arc seat 4631 is fixedly connected to the movable tube 461, the inner wall of the arc seat 4631 is fixedly connected to a number of bristles 4632, and the bristles 4632 are in contact with the outer wall of the cement pile 6, the interior of the arc seat 4631 is a hollow structure, the inner side of the arc seat 4631 is communicated with the interior of the movable tube 461, and the inner wall of the arc seat 4631 is provided with a number of paint leakage holes 4633 for draining the paint liquid.

[0023] The anti-corrosion paint liquid is introduced into the paint guide hose 464 through the painting component 46, and then introduced into the movable tube 461 through the paint guide hose 464, and then introduced into the arc seat 4631 through the movable tube 461. The anti-corrosion paint liquid inside the arc seat 4631 will leak out from the paint leakage hole 4633 and adhere to the bristles 4632 on the inner wall of the arc seat 4631. The bristles 4632 can paint the anti-corrosion paint liquid on the outer wall of the cement pile 6 through the translation of the arc seat 4631, thereby completing the painting work of the cement pile 6.

[0024] Furthermore, the paint supply assembly 40 includes a pump body 401, which is fixedly mounted on the outside of the mounting frame 5. The bottom of the mounting frame 5 is rotatably connected to a first pulley 402 coaxially fixed with the impeller of the pump body 401. The bottom end of the rotating shaft 42 is fixedly connected to a second pulley 403. The second pulley 403 is connected to the first pulley 402 through a belt drive. The inlet end of the pump body 401 is fixedly connected to a paint inlet pipe 404. The inlet end of the paint inlet pipe 404 is fixedly connected to a bellows telescopic pipe 405. The inlet end of the bellows telescopic pipe 405 is connected to the inside of the paint storage box 49, and the outlet end of the pump body 401 is connected to the paint guide hose 464. The motor 41 drives the rotating shaft 42 to rotate, which causes the second pulley 403 to rotate, and the first pulley 402 to rotate synchronously, causing the impeller of the pump body 401 to rotate, so that the interior of the pump body 401 is in a negative pressure state, so that the bellows 405 introduces the anti-corrosion paint liquid inside the paint storage box 49 into the pump body 401, and then the outlet end of the pump body 401 is discharged and introduced into the paint guide hose 464, and then the anti-corrosion paint liquid is introduced into the movable tube 461 through the paint guide hose 464, and then the anti-corrosion paint liquid is introduced into the interior of the arc seat 4631 through the movable tube 461, and the anti-corrosion paint liquid inside the arc seat 4631 will leak out from the paint leakage hole 4633 and adhere to the bristles 4632 on the inner wall of the arc seat 4631. The translation of the arc seat 4631 can make the bristles 4632 apply the anti-corrosion paint liquid to the outer wall of the cement pile 6, thereby realizing the painting work of the cement pile 6. Furthermore, the transmission member 47 includes an incomplete gear 471, which is fixedly connected to the output shaft of the motor 41. The top of the screw rod 43 is fixedly connected to a transmission gear 472, and the incomplete gear 471 intermittently meshes with the transmission gear 472. The motor 41 drives the rotating shaft 42 to rotate, causing the incomplete gear 471 to rotate. When the incomplete gear 471 meshes with the transmission gear 472, the transmission gear 472 drives the screw rod 43 to rotate synchronously. When the incomplete gear 471 disengages from the transmission gear 472, the screw rod 43 stops rotating. This cycle repeats, and the screw rod 43 can achieve intermittent rotation.

[0025] Furthermore, the linkage member 48 includes an eccentric wheel 481, which is fixedly connected to the bottom end of the rotating shaft 42. The outer edge of the eccentric wheel 481 is rotatably connected to a connecting rod 482 via a pin. The end of the connecting rod 482 away from the eccentric wheel 481 is hingedly connected to a connecting seat 483, and one end of the connecting seat 483 is fixedly connected to the end of the movable tube 461. The motor 41 drives the rotating shaft 42 to rotate, causing the eccentric wheel 481 to rotate synchronously, causing the connecting rod 482 to drive the connecting seat 483 to reciprocate, thereby causing the movable tube 461 to reciprocate along the guide groove 451.

[0026] Working principle: The pile driver 1 is used to press the cement pile 6 and keep the cement pile 6 stable. Then the hydraulic rod 3 is controlled to move the mounting frame 5 closer to the cement pile 6. This causes the curved plate 45 to move to the outer edge of the cement pile 6, so that the bristles 4632 come into contact with the cement pile 6. Then, the motor 41 is started to drive the rotating shaft 42 to rotate, causing the second pulley 403 to rotate, which in turn causes the first pulley 402 to rotate synchronously, causing the impeller of the pump body 401 to rotate, thereby causing the interior of the pump body 401 to be in a negative pressure state, so that the bellows 405 guides the anti-corrosion paint liquid in the paint storage box 49 into the pump body 401, and then the outlet end of the pump body 401 discharges the anti-corrosion paint liquid and guides it into the paint guide hose 464, and then guides the anti-corrosion paint liquid into the movable tube 461 through the paint guide hose 464, and then guides the anti-corrosion paint liquid into the arc seat 4631 through the movable tube 461, and the anti-corrosion paint liquid in the arc seat 4631 will leak out from the paint leakage hole 4633 and adhere to the bristles 4632 on the inner wall of the arc seat 4631; When the rotating shaft 42 rotates, it drives the eccentric wheel 481 to rotate synchronously, so that the connecting rod 482 drives the connecting seat 483 to reciprocate, so that the movable tube 461 reciprocates along the guide groove 451, so that the bristles 4632 on the inner wall of the arc seat 4631 apply the anti-corrosion paint liquid to the outer wall of the cement pile 6. At the same time, the rotating shaft 42 drives the incomplete gear 471 to rotate. When the incomplete gear 471 is engaged with the transmission gear 472, the transmission gear 472 drives the screw rod 43 to rotate synchronously. When the incomplete gear 471 is disengaged from the transmission gear 472, the screw rod 43 stops rotating. In this cycle, the screw rod 43 can realize intermittent rotation, so that the movable seat 44 can intermittently translate upward, which makes the arc seat 44 move upward. The plate 45 follows the movable seat 44 to intermittently translate upward, so that the bristles 4632 on the inner wall of the arc seat 4631 can paint the outer wall of the cement pile 6 in the vertical direction. Since the curvature of the guide groove 451 is 180 degrees, the painting component 46 can paint half of the surface of the cement pile 6. When half of the outer wall of the cement pile 6 is painted, the position of the cab of the pile driving machine body 1 is adjusted to allow the painting component 46 to paint the other half of the outer wall of the cement pile 6, thereby achieving full painting of the outer wall of the cement pile 6. The entire process only requires the driver of the pile driving machine body 1 to operate alone to achieve automatic painting of the cement pile 6, which not only improves the painting efficiency but also reduces safety risks.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
