Description

Technical Field

[0001] This invention relates to the field of three-dimensional circulating steam curing technology for utility poles, specifically to a three-dimensional circulating steam curing device for annular concrete utility poles. Background Technology

[0002] Steam curing of concrete poles involves spraying saturated steam directly onto the outer surface of the concrete pole. The high temperature and humidity of the steam coats the surface of the pole, promoting cement hydration and thus accelerating strength growth. During construction, the steam temperature and spraying rate are controlled to prevent cracks from appearing on the pole surface due to sudden heating and cooling. By continuously supplying a humid and hot environment to the pole surface, the curing cycle is shortened.

[0003] However, existing technologies still have drawbacks, such as the need for continuous manual rotation of the annular concrete pole, which leads to the lack of a limit roller pressing position at the top, causing the pole to jump during rotation. Furthermore, existing technologies cannot adjust the spacing of each arc plate according to the severity of the outer wall condition of the annular concrete pole, resulting in the inability to switch between intensive and loose air-jet curing. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of existing devices that still require continuous manual rotation of the annular concrete pole, which leads to jumping during rotation due to the lack of a limiting roller pressing position at the top. Furthermore, existing technology cannot adjust the spacing of each arc plate according to the severity of the outer wall condition of the annular concrete pole, resulting in the inability to switch between intensive and loose steam curing. Therefore, this invention proposes a three-dimensional circulating steam curing device for annular concrete poles.

[0005] To achieve the above objectives, the present invention provides the following technical solution: Design a three-dimensional circulating steam curing device for annular concrete poles, comprising annular concrete poles, pole bases, and a base. The pole base is fixedly connected to the end of the annular concrete pole. Multiple reinforcing bars are fixedly connected to the rear side of the outer wall of the pole base, and the reinforcing bars penetrate the inner wall of the annular concrete pole. The upper ends of the base are fixedly connected to multiple support frames on both sides by I-beams. A drive assembly is installed on the left end of the upper surface of the base, and a jet assembly is installed on the right end of the upper surface of the base.

[0006] Preferably, the drive assembly includes a connecting crossbar, a servo motor, a drive roller, an arc-shaped bracket, a base, an electric push rod, and a groove plate; Multiple bases are fixed to the upper left front and rear parts of the base. An arc-shaped bracket is rotatably connected to the inner outer wall of the base. The upper inner wall of the arc-shaped bracket is rotatably connected to the drive roller through a bearing. The end of the rotating part of the drive roller is fixedly connected to the output shaft of the first servo motor. The main body of the first servo motor is fixedly connected to the arc-shaped bracket. The center of the outer wall of the arc-shaped bracket is fixedly connected through a connecting crossbar. The connecting crossbar passes through and is slidably connected to the inner wall of the slot plate. The lower end of the slot plate is fixedly connected to the output shaft of the electric push rod. The lower end of the electric push rod is fixedly connected to the base.

[0007] Preferably, the upper inner walls of the plurality of support frames are rotatably connected to support rollers, and the upper outer walls of the support rollers are in contact with the outer wall of the annular concrete pole.

[0008] Preferably, the upper right side of the base is fixedly connected to both the front and rear parts of the base, and a sliding rod is fixedly connected to the center of the outer wall of the end plate.

[0009] Preferably, the upper inner wall of the end plate is rotatably connected to the threaded rod via a bearing, the end of the threaded rod is fixedly connected to the output shaft of the second servo motor, and the main body of the second servo motor is fixedly connected to the front end plate.

[0010] Preferably, the jet assembly includes a sleeve, a sliding platform, a crossbeam support, a crossbeam, an arc plate, a jet nozzle, an air inlet, and a diagonal connecting rod; The inner wall of the sliding platform is threadedly connected to the outer wall of the threaded rod. The lower inner wall of the sliding platform is slidably connected to the slide rod. The upper end of the sliding platform is fixedly connected to the crossbeam via a crossbeam bracket. The outer walls of the crossbeams are all fixedly connected to the sleeves, and the outer walls of the sleeves are all fixedly connected to the arc-shaped plate. The inner wall of the arc-shaped plate is machined with multiple air jet holes. The upper part of the outer wall of the arc-shaped plate is machined with an air intake pipe. The outer wall of the air intake pipe is rotatably connected to the pins via multiple oblique connecting rods.

[0011] Preferably, the inner wall of the intersection of the oblique connecting rod is rotatably connected to the air intake pipe, and the ends of the oblique connecting rod are rotatably connected by pins.

[0012] Preferably, the bottom outer edge of the pole base is provided with equidistant insertion holes, and the rear side of the reinforcing bar protrudes from the end of the annular concrete pole.

[0013] The three-dimensional circulating steam curing equipment for annular concrete poles proposed in this invention has the following advantages: Through the cooperation between the drive roller, support roller, annular concrete pole, servo motor 1, and trough plate, the drive roller and the support rollers on both sides at the bottom work together to limit the position of the annular concrete pole, preventing it from jumping out of its support position when rotating and spraying air. When it is necessary to control the rotation of the annular concrete pole, the user can control the servo motors on both sides to start synchronously, so that the output shaft of the servo motor 1 can drive the drive roller to rotate synchronously, thereby driving the annular concrete pole to rotate. After the steam air curing of the annular concrete pole is completed, the output shaft of the electric push rod can be controlled to retract, so that the output shaft of the electric push rod can drive the trough plate to move downward, thereby pulling the arc bracket to rotate outward and unfold, so that the drive roller moves away from above the annular concrete pole. Then, the annular concrete pole can be removed by a crane or other equipment. This effectively avoids the problem that the drive and support parts of the existing annular concrete pole are generally at the bottom, resulting in no limit roller pressing at the top, which makes it easy to jump during rotation. By coordinating the annular concrete pole, air inlet pipe, curved plates, and exhaust port, the user can rotate the annular concrete pole and insert an external steam hose into the air inlet pipe. The spacing of the curved plates is then adjusted according to the severity of the outer wall condition of the annular concrete pole. If dense steam jetting is needed, the spacing is reduced; conversely, it is increased. Due to the constraints of multiple diagonal connecting rods, the spacing of the curved plates remains consistent. After adjusting the spacing, the user can fix the position by tightening bolts on the sleeve. External steam is then injected into the curved plates through the air inlet pipe and finally discharged from the exhaust port, spraying onto the surface of the annular concrete pole. Combined with the 360° rotation of the annular concrete pole, steam jetting curing is achieved across the entire circumference of the corresponding location. This avoids the problem of existing technologies being unable to adjust the spacing of the curved plates according to the severity of the outer wall condition, thus preventing the switching between dense and loose steam jetting curing.

[0016] The present invention will be further described below with reference to the accompanying drawings: See attached document Figure 1-9 In this embodiment, a three-dimensional circulating steam curing device for annular concrete poles includes annular concrete pole 1, pole base 2, and base 5. The pole base 2 is fixedly connected to the end of the annular concrete pole 1. Multiple reinforcing bars 14 are fixedly connected to the rear side of the outer wall of the pole base 2. The reinforcing bars 14 penetrate the inner wall of the annular concrete pole 1. The upper ends of the base 5 are fixedly connected to multiple support frames 10 by I-beams 11 on both sides. In order to provide sufficient strength to support the annular concrete pole 1, the I-beams 11 are used to support the annular concrete pole 1. A drive assembly 3 is installed on the left end of the upper surface of the base 5, and a jet assembly 4 is installed on the right end of the upper surface of the base 5. The upper inner walls of the multiple support frames 10 are rotatably connected to support rollers 9. The support rollers 9 are used to support the overall weight of the annular concrete pole 1 at the bottom. The upper outer wall of the support rollers 9 is in contact with the outer wall of the annular concrete pole 1. The upper right side of the base 5 is fixedly connected to both the front and rear ends of the end plate 13. A sliding rod 12 is fixedly connected to the center of the outer wall of the end plate 13.

[0017] The upper inner wall of the end plate 13 is rotatably connected to the threaded rod 8 via a bearing. The servo motor 7 can drive the threaded rod 8 to rotate. In specific operation, if the weight of the sliding platform 402 is large, a reducer can be installed between the servo motor 7 and the threaded rod 8 to provide sufficient torque. The end of the threaded rod 8 is fixedly connected to the output shaft of the servo motor 7. The specific model of the servo motor 7 can be determined according to the application. The main body of the servo motor 7 is fixedly connected to the end plate 13 on the front side. The bottom outer edge of the pole base 2 is equidistantly machined with insertion holes 6. The insertion holes 6 facilitate the insertion of the protruding steel bars 14 when assembling and connecting multiple annular concrete poles 1 for easy connection. The rear side of the steel bars 14 protrudes from the end of the annular concrete pole 1.

[0018] See attached document Figure 1-9 In this embodiment, the drive assembly 3 includes a connecting crossbar 301, a servo motor 302, a drive roller 303, an arc-shaped bracket 304, a base 305, an electric push rod 306, and a groove plate 307. Multiple bases 305 are fixed to the upper left front and rear parts of the base 5. The inner outer wall of the base 305 is rotatably connected to an arc-shaped bracket 304. The upper inner wall of the arc-shaped bracket 304 is rotatably connected to the drive roller 303 through a bearing. The arc-shaped bracket 304 can provide rotational support for the drive roller 303. The end of the rotating part of the drive roller 303 is fixedly connected to the output shaft of the servo motor 302. The specific model of the servo motor 302 can be determined according to the application. The output shaft of the servo motor 302 can drive the drive roller 303 to rotate. Similarly, if the torque required for the rotation of the annular concrete pole 1 is too large, a reducer can be installed between the servo motor 302 and the drive roller 303 to provide sufficient torque.

[0019] The main body of the servo motor 302 is fixedly connected to the arc-shaped bracket 304. The center of the outer wall of the arc-shaped bracket 304 is fixedly connected by a connecting crossbar 301. The connecting crossbar 301 passes through and slides with the inner wall of the slot plate 307. The lower end of the slot plate 307 is fixedly connected to the output shaft of the electric push rod 306. The specific model of the electric push rod 306 may be determined according to the specific application. The lower end of the electric push rod 306 is fixedly connected to the base 5.

[0020] See attached document Figure 1-9 In this embodiment, the jet assembly 4 includes a sleeve 401, a sliding platform 402, a crossbeam support 403, a crossbeam 404, an arc plate 405, a jet nozzle 406, an air inlet 407, and an oblique connecting rod 408. The inner wall of the sliding platform 402 is threadedly connected to the outer wall of the threaded rod 8. The rotation of the threaded rod 8 can drive the sliding platform 402 to move. When the threaded rod 8 reverses, it can drive the sliding platform 402 to move in the opposite direction. The lower inner wall of the sliding platform 402 is slidably connected to the slide rod 12. The upper end of the sliding platform 402 is fixedly connected to the crossbeam 404 through the crossbeam bracket 403. The outer wall of the crossbeam 404 is fixedly connected to the sleeve 401. The crossbeam 404 can provide sliding support for the sleeve 401 and the arc plate 405, and the outer wall of the sleeve 401 is fixedly connected to the arc plate 405.

[0021] The inner wall of the arc plate 405 is machined with multiple air jet holes 406, and the upper part of the outer wall of the arc plate 405 is machined with an air inlet pipe 407. An external steam hose can be inserted into the notch of the air inlet pipe 407. At the same time, external steam is sent into the interior of the arc plate 405 through the air inlet pipe 407 and finally discharged from the exhaust hole 406. The outer wall of the air inlet pipe 407 is rotatably connected to the pin by multiple oblique connecting rods 408. The cooperation of multiple oblique connecting rods 408 and pins can ensure that the spacing between adjacent arc plates 405 remains consistent. The inner wall of the intersection of the oblique connecting rods 408 is rotatably connected to the air inlet pipe 407, and the ends of the oblique connecting rods 408 are all rotatably connected by pins.

[0022] Working principle: When this three-dimensional circulating steam curing equipment for annular concrete poles is needed, it is first placed above the support rollers 9 on both sides using equipment such as a crane, and the center position of the support rollers 9 is determined (so that they do not protrude beyond the base 5). This completes the rotational support of the annular concrete pole 1. Then, the electric push rod 306 is controlled so that the output shaft of the electric push rod 306 can drive the groove plate 307 to move downward. The downward movement of the groove plate 307 can push the connecting crossbar 301 to move upward, and then the arc-shaped bracket 304 rotates around the rotation center at the bottom, so that the drive roller 303 is pressed tightly against the surface of the support roller 9.

[0023] The drive roller 303, in conjunction with the support rollers 9 on both sides at the bottom, restricts the position of the annular concrete pole 1, preventing it from jumping out of its support position during steam injection. When the rotation of the annular concrete pole 1 needs to be controlled, the user can control the servo motors 302 on both sides to start synchronously, so that the output shaft of the servo motors 302 can drive the drive roller 303 to rotate synchronously, thereby driving the annular concrete pole 1 to rotate. After the steam injection curing of the annular concrete pole 1 is completed, the output shaft of the electric push rod 306 can be controlled to retract, so that the output shaft of the electric push rod 306 can drive the groove plate 307 to move downward, thereby pulling the arc bracket 304 to rotate outward and unfold, so that the drive roller 303 can move away from above the annular concrete pole 1. Then, the annular concrete pole 1 can be removed by a crane or other equipment. This effectively avoids the problem of the existing technology requiring constant manual rotation of the annular concrete pole 1 and the lack of a limiting roller pressing at the top, which easily leads to jumping during rotation.

[0024] After the annular concrete pole 1 can be rotated, the user can insert an external steam hose into the air inlet pipe 407. Then, the spacing of each arc plate 305 can be adjusted according to the severity of the condition of the outer wall of the annular concrete pole. If dense steam jetting is required, the spacing of each arc plate 305 can be reduced, and vice versa. Due to the constraint of multiple inclined connecting rods 408, the spacing of the arc plates 305 remains consistent. After the spacing adjustment is completed, the user can fix the position by tightening the bolts on the sleeve 401. Then, external steam can be injected into the arc plates 405 through the air inlet pipe 407 and finally discharged from the jet hole 406, spraying onto the surface of the annular concrete pole 1. Combined with the 360° rotation of the annular concrete pole 1, steam jetting curing can be achieved for the entire circumference area of ​​the corresponding position. This avoids the problem that the existing technology cannot adjust the spacing of each arc plate 305 according to the severity of the condition of the outer wall of the annular concrete pole, which makes it impossible to switch between dense jetting curing and loose jetting curing.

[0025] After completing the circumferential steam jet curing at a single position, the user can control the servo motor 7, so that the output shaft of the servo motor 7 can drive the threaded rod 8 to rotate, so that the threaded rod 8 can drive the sliding platform 402 to move back and forth to perform the circumferential steam jet curing at the next station. This process is repeated continuously to achieve a three-dimensional cyclic steam processing operation.

[0026] Finally, the control process in this case can be controlled by a PLC controller, specifically servo motor 1 302, servo motor 2 7, and electric push rod 306. The control content can include control, movement, pressure adjustment, self-locking, linkage, stroke and other specific data control. At the same time, the specific design can be adjusted to a detachable structure according to actual needs, so as to realize periodic disassembly and cleaning. If the environment is not a dusty environment, the electronic components can be directly covered for rinsing.

[0027] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art will understand that various changes in form and detail are possible within the scope of the claims.
