Description

Technical Field

[0001] This invention relates to the field of cement pole maintenance technology, and more particularly to a maintenance device for cement pole production. Background Technology

[0002] In the production process of cement poles, the curing process after the poles are formed is a key step that determines their final strength and durability. Currently, most manufacturers still use manual watering or simple soaking methods to cure the poles, which has the following problems: First, manual watering makes it difficult to ensure uniformity of maintenance. Different parts of the pole surface receive different amounts of water, which can easily lead to insufficient local strength or surface cracking, affecting product quality. Second, traditional maintenance methods waste water resources seriously, with a large amount of maintenance water being discharged directly without being recycled, which does not meet the requirements of energy-saving and environmentally friendly production. Third, the lack of effective surface cleaning and moisturizing measures during the maintenance process means that the residual slurry and dust on the pole surface will affect the quality of subsequent surface treatment processes if not cleaned in time. Fourth, the existing equipment has a low degree of automation. Operations such as pole picking, spraying, and covering rely on manual labor, which is labor-intensive and has low production efficiency, making it difficult to meet the needs of large-scale production. To address the aforementioned problems, this invention provides a cement pole maintenance device that integrates rotary spraying, surface cleaning, automatic film coating, automatic cutting, and automatic feeding and discharging. Summary of the Invention

[0003] In order to overcome the shortcomings of existing cement pole maintenance methods, such as uneven maintenance, serious waste of water resources, lack of surface cleaning function, and low degree of automation, this invention provides a maintenance equipment for cement pole production.

[0004] Its core design concept is to realize the fully automated operation of cement poles from spray curing to film protection by constructing a comprehensive maintenance platform that integrates active rotation support, reciprocating scanning spraying, pole surface cleaning and smoothing, automatic film wrapping, fixed length cutting and adaptive feeding and discharging.

[0005] From the perspective of structural layout and working principle, this invention first sets up an open water tank as a water storage base. A swing frame that can be deflected as a whole is formed by symmetrically arranged support rods and mounting structures on both sides of the water tank. A reciprocating motion mechanism driven by a screw is installed on this frame, allowing the arc-shaped spray pipe to scan back and forth along the longitudinal direction of the cement pole. In conjunction with this, a motor-driven roller system is configured inside the water tank, causing the cement pole to continuously rotate around its own axis during spraying. This composite motion mode of pole rotation + axial reciprocating scanning of the nozzle ensures that the curing water can cover the entire pole surface without dead angles, solving the problem of uneven coverage caused by traditional fixed-point spraying from a kinematic perspective.

[0006] To further improve the maintenance effect and resource utilization, this invention integrates splash guards and arc-shaped covers with brush components on both sides of the spray pipe. By utilizing the relative motion of the rotating rod, the surface slurry is removed and the water film is applied evenly at the same time, which not only improves the cleanliness but also makes the maintenance water form a continuous and uniform liquid film on the rod surface. At the same time, the baffles effectively restrict the diffusion range of the sprayed water mist, allowing most of the water to flow back to the water tank for recycling.

[0007] In the film-laying stage after curing, this invention employs a passive friction-driven film-laying scheme. Specifically, the power for the film-laying mechanism comes from the rotational motion of the cement pole itself. Through the contact between the toothed wheel located below the support roller and the pole surface, the rotational motion of the pole is transmitted to the pressure roller assembly at the film outlet via a belt drive mechanism, thereby continuously pulling the curing film out. This design concept eliminates the need for a separate film-laying drive source, simplifying the power system. In addition, this invention also includes a pressure rod assembly that swings under gravity to eliminate air bubbles between the film material and the pole surface, and, combined with a cam that moves with the spray pipe, generates a compaction effect, ensuring the tightness and quality of the film application from multiple perspectives.

[0008] To address the issue of fixed-length cutting of curing films, this invention proposes a purely mechanically triggered automatic cutting scheme. This scheme utilizes the reciprocating motion of the arc-shaped spray pipe as the driving force. A guide tube-telescopic rod-moving block assembly installed at one end of the spray pipe actuates the cutter to perform the cutting action when the spray pipe moves to a specific position. Simultaneously, the movable block automatically lifts and disengages during the return stroke, thanks to the cooperation of the fixed inclined rail and the inclined surface of the fixed rod on the telescopic rod. A return spring then automatically returns the cutter to its original position. The entire cutting process requires no electrical control signals, offering higher reliability and lower manufacturing costs in humid curing environments.

[0009] In addition, to meet the production needs of cement poles of different lengths, the present invention has set up a feeding and discharging system consisting of multiple independent units at the bottom of the water tank. Each unit adopts a structure of dual-shaft motor-driven gear rack lifting, which can flexibly select and activate the corresponding number and position of units for synchronous lifting according to the actual pole length, thus optimizing energy consumption while ensuring stability.

[0010] In summary, through the above-mentioned structural innovations and functional integration, this invention achieves high efficiency, uniformity, and automation in the maintenance process of cement poles.

[0011] The beneficial effects are: First, it ensures uniform curing. Through the combined motion of the reciprocating movement of the nozzle and the rotation of the cement pole itself, it achieves uniform spraying and curing of the pole surface in all directions without dead angles, which significantly improves the curing quality. Secondly, it is water-saving and efficient. The baffles on both sides of the arc-shaped pipe effectively prevent water splashing, and the water recycling design greatly improves the utilization rate of water resources. Third, it integrates functions such as surface cleaning, automatic film coating and moisturizing, and automatic cutting, which reduces manual intervention and improves production efficiency. Fourth, automatic film cutting: Through the mechanical triggering cutting structure of the movable block and the inclined rail, automatic film cutting is achieved after the film is coated, without the need for external electrical control signals, which reduces manufacturing costs and improves the reliability of the equipment in humid environments. Fifth, it has a high degree of automation. Through the coordinated control of components such as cylinders and motors, and in conjunction with automatic feeding and discharging devices, it can achieve continuous and automated operation, effectively reducing the intensity of manual labor. Sixth, it is highly adaptable; by adjusting the various moving parts, it can adapt to the maintenance needs of cement poles of different diameters and lengths. Attached Figure Description

Detailed Implementation

[0014] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0015] I. Overall Equipment Structure Reference Figure 1 and Figure 2 The cement pole maintenance equipment proposed in this invention mainly includes the following components in its overall structure: a rectangular water tank 100 with an open top as the base for holding circulating maintenance water; a spraying system installed above the water tank; a rotating support system installed inside the water tank; and a film-laying mechanism and an automatic feeding and discharging mechanism installed in the bottom area of ​​the inner cavity of the water tank.

[0016] The water tank 100 is welded from steel plates with a certain wall thickness, and its internal space is designed with sufficient length and width according to the specifications of commonly used cement poles. Support rods 101 are erected and fixed on both sides of the upper edge of the water tank 100, and the upper ends of the two support rods 101 are hinged to one end of a mounting bracket 102. The two mounting brackets 102 are rigidly connected by a transversely arranged connecting rod 103, thus forming a synchronously swinging overall frame. A first cylinder 104 is hinged to the outer bottom of the water tank 100, and the end of the cylinder's extension rod extends towards... The upper part extends and is hinged to the middle of the connecting rod 103; when the telescopic rod of the first cylinder 104 extends or retracts, the mounting brackets 102 on both sides are driven to rotate around the hinge point between them and the support rod 101 through the connecting rod 103, thereby adjusting the tilt angle of the entire upper frame; this adjustment function has two main purposes: first, for cement poles of different diameters, the spraying distance of the spraying system can be adjusted by changing the tilt angle of the mounting bracket 102, so that the nozzle and the pole surface maintain the optimal working distance; second, the mounting bracket 102 can be rotated to one side during loading and unloading, so as to make room for operation at the end of the cement pole.

[0017] Reference Figure 2 Inside the water tank 100, two parallel rollers 105 are installed along the width direction. The two ends of the rollers 105 are rotatably engaged with the side wall of the water tank 100 through bearing seats. Each roller 105 is fixedly fitted with multiple support rollers 107. The wheel surface of the support rollers 107 is machined with an arc-shaped groove that is adapted to the outer diameter of the cement rod 800. The cement rod 800 is mounted between the support rollers 107 of the two rollers 105, and is supported and driven by the support rollers 107. A first motor 106 is fixedly installed on the outer wall of the water tank 100. The output shaft of the motor is connected to the shaft end of one of the rollers 105 through a coupling. When the first motor 106 is powered on, it drives the roller 105 connected to it and the support rollers 107 on the roller to rotate. The friction between the support rollers 107 and the surface of the cement rod 800 drives the cement rod 800 to slowly rotate around its own axis, so that the entire circumference of the rod passes through the spray area and the cleaning area in sequence.

[0018] II. Structural Principles and Working Methods of Sprinkler Systems Reference Figure 1 A reciprocating screw 200 is installed across the space above the two mounting brackets 102. The two ends of the reciprocating screw 200 are rotatably connected to the two mounting brackets 102 through bearing seats. One end of the reciprocating screw 200 extends out of the mounting bracket 102 and is connected to the output shaft of the second motor 201 fixed on the outside of the mounting bracket 102. When the second motor 201 is running, it drives the reciprocating screw 200 to rotate in the forward or reverse direction in its original position. On the left and right sides of the reciprocating screw 200, two sliding rods 202 are arranged in parallel. The two ends of the sliding rods 202 are fixedly connected to the mounting brackets 102 on both sides, forming a stable guide rail.

[0019] A reciprocating nut 203 is fitted onto the reciprocating screw 200. The internal thread of the nut and the external thread of the screw form a helical drive engagement. Guide holes are provided on the left and right sides of the reciprocating nut 203, and two sliding rods 202 pass through the corresponding guide holes, thereby restricting the reciprocating nut 203 from rotating with the screw and making it only able to move linearly along the axis of the sliding rods 202. When the second motor 201 drives the reciprocating screw 200 to rotate continuously, since the thread direction on the screw surface reverses at both ends, the reciprocating nut 203 will automatically reverse direction when it moves to the end of the screw, thereby realizing reciprocating linear motion along the sliding rods 202.

[0020] A curved tube 300 is fixedly connected to the lower part of the reciprocating nut 203. The curvature of the curved tube 300 is designed according to the diameter range of the cement pole 800, so that its inner arc surface is approximately concentric with the outer circle of the cement pole 800. On the inner arc surface of the curved tube 300, multiple nozzles 301 are evenly installed along the arc length direction. The spray direction of each nozzle 301 is pointing towards the center of the curved tube 300, that is, towards the surface of the cement pole 800. A water pump (not shown in the figure) is installed inside the water tank 100. The water pump's suction port is submerged below the water surface in the water tank 100, and its outlet is connected to the inner cavity of the curved tube 300 through a flexible hose. When the water pump is working, it pressurizes and delivers the curing water in the water tank 100 to the curved tube 300, and then sprays it out in a fan shape by each nozzle 301.

[0021] During the spraying operation, the cement pole 800 rotates continuously under the drive of the support roller 107, while the arc-shaped pipe 300 and the nozzle 301 reciprocate along the axial direction of the cement pole 800 under the drive of the reciprocating screw 200. The combined effect of these two movements is that the spray point of the nozzle 301 moves in a spiral scanning pattern relative to the surface of the cement pole 800, sweeping across every tiny area of ​​the pole surface in sequence, thereby ensuring that the curing water achieves a macroscopic and uniform coverage on the surface of the pole. After being sprayed onto the surface of the cement pole 800, excess water flows downward under the action of gravity, falls back into the water tank 100 through the gap between the support roller 107 and the roller 105, and realizes the recycling of water resources.

[0022] III. Surface Cleaning and Water Film Control Structure Reference Figure 2 On the left and right sides of the arc-shaped tube 300, there are downward extending baffles 302. The baffles 302 are made of thin steel plates with smooth inner surfaces and their shapes match the curvature of the arc-shaped tube 300. The main function of the baffles 302 is to restrict the splash range of the spray water mist and prevent the high-pressure water mist from spreading outward from both ends of the arc-shaped tube 300, which reduces the waste of water resources and avoids the water mist from corroding the surrounding environment and other equipment.

[0023] An arc-shaped cover 303 is fixedly connected to the edge of the baffle 302 facing the cement pole 800. The arc-shaped cover 303 is also arc-shaped, and its inner arc surface maintains a very small gap with the surface of the cement pole 800. A brush 304 and an elastic scraper 305 arranged along the arc length direction are fixedly installed in the internal space of the arc-shaped cover 303. The brush 304 is located on the side closer to the spray area of ​​the arc-shaped pipe 300, and the elastic scraper 305 is located on the side away from the spray area. When the cement pole 800 rotates under the drive of the support roller 107, the surface of the pole first passes the position of the brush 304. The bristles of brush 04 slide and rub against the shaft surface, brushing off the laitance, dust, and other impurities adhering to the shaft surface during the maintenance process, which are then rinsed away by the spray water. After brushing, the shaft surface continues to rotate to the position of the elastic scraper 305. The elastic scraper 305 is made of rubber or polyurethane material with a certain degree of elasticity. Its blade slides closely against the shaft surface, scraping off excess water and evenly applying the remaining maintenance water into a continuous, thin, and complete water film. This sequential treatment method of cleaning first and then smoothing not only ensures the cleanliness of the shaft surface but also creates good surface conditions for subsequent even maintenance.

[0024] IV. Assembly Relationship and Transmission Principle of the Film Laying Mechanism Reference Figure 1 , Figure 3 , Figure 6 and Figure 7 A horizontally arranged crossbeam 400 is fixedly installed inside the lower part of the water tank 100. The two ends of the crossbeam 400 are welded or bolted to the side wall of the water tank 100 to form a stable installation base. The frame 401 of the film laying mechanism is installed above the crossbeam 400. The frame 401 is located in the space below the support roller 107, making full use of the three-dimensional space inside the water tank 100.

[0025] At the rear end of the frame 401 (with reference to the axial direction of the cement pole 800, near the end of the film winding wheel), a film winding wheel 402 is rotatably supported. A roll of curing film (usually plastic film or laminated non-woven fabric) is wound on the film winding wheel 402. At the front end of the frame 401, a film outlet nozzle 404 is provided. The film outlet nozzle 404 is a guide component with a flat outlet, used to guide the curing film to the surface of the cement pole 800 in the correct orientation. A transition wheel 403 is rotatably installed in the middle area of ​​the frame 401. The curing film drawn from the film winding wheel 402 passes around the transition wheel 403 in sequence and enters the film outlet nozzle 404. The transition wheel 403 plays the role of changing the direction of the film material and keeping the film surface flat.

[0026] Reference Figure 3 and Figure 7The outlet nozzle 404 has two pressure rollers 405 installed inside, arranged vertically opposite each other, with a gap between them just wide enough for the curing membrane to pass through. The surfaces of the two pressure rollers 405 are covered with rubber material with a certain coefficient of friction to ensure the clamping force on the membrane material. A first pulley 406 is fixedly installed on the shaft end of one of the pressure rollers 405 (the active pressure roller). On one side below the outlet nozzle 404, a toothed wheel 407 is rotatably installed via a bracket. The circumference of the toothed wheel 407 is evenly distributed with raised teeth or knurling to increase the friction with the surface of the cement pole 800. A second pulley 408 is coaxially fixed on one side of the toothed wheel 407. The first pulley 406 and the second pulley 408 are connected by a ring belt 409.

[0027] Reference Figure 3 The installation position of the roller 407 is carefully designed so that it is located slightly off to one side below the support roller 107. When the cement rod 800 is placed on the support roller 107, the lower outer surface of the cement rod 800 forms a slight pressure contact with the tooth surface of the roller 407. When the first motor 106 drives the cement rod 800 to rotate, the rotational motion of the rod surface is transmitted to the roller 407 through friction, driving the roller 407 to rotate synchronously. The rotation of the roller 407 is transmitted to the driving pressure roller 405 through the coaxial second pulley 408, belt 409 and first pulley 406, so that the driving pressure roller 405 obtains rotational driving force. The driving pressure roller 405 then drives the driven pressure roller 405 to rotate in the opposite direction through the friction of its surface (the two are meshed by gears, see below for details), thereby pulling the curing film held between the two pressure rollers 405 off the film winding roller 402 and continuously conveying it towards the outlet direction of the film outlet nozzle 404.

[0028] This method of using the rotational energy of cement poles to drive membrane laying eliminates the need for additional drive motors and supporting control circuits, reducing equipment costs and failure rates, and is especially suitable for curing environments with high water content.

[0029] V. Pressure Roller Synchronization and Membrane Material Pressing Structure Reference Figure 8 Two pressure rollers 405 are mounted on the shaft ends on the same side, with meshing gears installed on each other. When one pressure roller 405 rotates under the drive of belt transmission, the other pressure roller 405 rotates synchronously at the same speed but in the opposite direction through the meshing of the gear pair. This synchronous reverse rotation clamping method ensures that the curing film is subjected to uniform traction between the two pressure rollers 405, avoiding problems such as film slippage, deviation, or uneven stretching caused by unilateral drive.

[0030] Reference Figure 3A transverse shaft 500 is fixed at the front end of the frame 401 (the end away from the film winding wheel 402). Multiple sets of pressure rods 501 are rotatably connected to the shaft 500. The pressure rods 501 are evenly distributed along the axial direction of the cement rod 800. The ends of the pressure rods 501 are connected into a whole by a connecting plate 502, so that all the pressure rods 501 can swing synchronously. The ends of the pressure rods 501 are bent and extend into the groove area of ​​the toothed wheel 407. When the curing film extends from the film outlet 404 and adheres to the surface of the cement rod 800, the pressure rods 501 hang down naturally around the shaft 500 under their own weight. Their ends press against the outer surface of the curing film, pushing the film material onto the surface of the cement rod 800. At the same time, as the cement rod 800 rotates, the pressure rods roll or slide along the rod surface, gradually driving the air bubbles between the film material and the rod surface from one side to the other, so as to achieve a tight fit between the film material and the rod body.

[0031] Reference Figure 3 A cam 503 is fixedly installed below the arc-shaped tube 300. The cam 503 has a protruding part on its profile. When the arc-shaped tube 300 reciprocates along the cement rod 800, the cam 503 moves along with it. When the protruding part of the cam 503 passes the position of the connecting plate 502 of the pressure rod 501, it will push the connecting plate 502 downward, so that each pressure rod 501 will get an additional downward torque. Then the cam 503 continues to move, and the pressure is released after the protruding part leaves the connecting plate 502. This intermittent pressure increase and decrease cycle applies a periodic vibration and compaction effect during the membrane bonding process, which helps to eliminate the tiny air bubbles remaining between the membrane and the rod surface and improve the coating quality.

[0032] VI. Triggering Principle and Reset Mechanism of Automatic Cutting Mechanism Reference Figure 6 , Figure 7 and Figure 9 A horizontal guide rod 600 is fixed at the front end of the frame 401. A paddle 601 is slidably sleeved on the guide rod 600. The paddle 601 can slide freely along the axial direction of the guide rod 600. A scriber 602 is fixedly connected to one end of the paddle 601. The blade of the scriber 602 extends into the cutting groove 4041 of the membrane outlet 404. The cutting groove 4041 is a narrow groove that runs horizontally through the membrane. The blade of the scriber 602 can move horizontally in the groove to cut the curing membrane that passes through the membrane outlet 404.

[0033] Reference Figure 9A guide tube 603 is fixed below the end of the arc-shaped tube 300 near the dispensing nozzle 404. The guide tube 603 is cylindrical, hollow inside, and open from top to bottom. A telescopic rod 604 is slidably fitted inside the guide tube 603 and can slide up and down inside the guide tube 603. The lower end of the telescopic rod 604 extends out from the lower end opening of the guide tube 603 and is hinged to a movable block 605 at its lower end by a pin. A first spring 607 is installed inside the guide tube 603. The spring is sleeved on the upper part of the telescopic rod 604. One end of the spring abuts against the inner wall step of the guide tube 603, and the other end abuts against the shoulder of the telescopic rod 604. It always applies a downward pushing force to the telescopic rod 604, so that the telescopic rod 604 remains in the extended state when there is no external force interference, pushing the movable block 605 to the lowest position. The lower end surface of the movable block 605 is a smooth inclined surface or arc surface for contacting the lever 601.

[0034] A longitudinal groove is opened on the side wall of the guide cylinder 603. A fixed rod 606 is horizontally fixed on the body of the telescopic rod 604. The outer end of the fixed rod 606 passes through the groove and extends to the outside of the guide cylinder 603, and can slide up and down along the groove. A section of inclined rail 608 is fixedly installed on the cross frame 400 at a position corresponding to the movement trajectory of the fixed rod 606. The inclined rail 608 has an inclined working surface that gradually rises from low to high.

[0035] The working principle of this automatic cutting mechanism is explained below with reference to a specific work process: When the arc-shaped tube 300 moves axially toward the dispensing nozzle 404, the guide tube 603, telescopic rod 604, and movable block 605 move synchronously with the arc-shaped tube 300 as a whole. At this time, under the elastic force of the first spring 607, the movable block 605 is in a low position, and its lower end face is lower than the upper end face of the pusher 601. When the movable block 605 encounters the pusher 601 during the translation process, the inclined part of its lower end face contacts the pusher 601 and applies a horizontal pushing force to it, pushing the pusher 601 to slide along the guide rod 600. The pusher 601 drives the scriber 602 to move laterally in the cutting groove 4041. The blade of the scriber 602 cuts from one edge of the curing film to the other side, cutting the continuously conveyed curing film laterally and completing the automatic film cutting action.

[0036] When the arc-shaped tube 300 completes its cutting stroke and moves in the opposite direction (i.e., away from the nozzle 404), the guide cylinder 603 drives the telescopic rod 604 and the fixed rod 606 to retract together. When the outer end of the fixed rod 606 moves to the position of the inclined rail 608, the fixed rod 606 gradually rises along the inclined working surface of the inclined rail 608, forcing the entire telescopic rod 604 to retract into the guide cylinder 603 against the elastic force of the first spring 607. Simultaneously, the rising of the telescopic rod 604 drives the movable block 605 to rise synchronously, making... The lower end face of the movable block 605 is raised to a position higher than the upper end face of the lever 601; at this time, the movable block 605 and the lever 601 are completely disengaged in the height direction. When the arc tube 300 continues to move in the opposite direction, the movable block 605 passes over the lever 601 without pushing the lever 601; after the fixed rod 606 has completely slid past the highest point of the ramp 608, the elastic force of the first spring 607 pushes the telescopic rod 604 out again, and the movable block 605 descends and resets to the low position, waiting for the next working cycle.

[0037] Reference Figure 6 A second spring 609 is also fitted on the guide rod 600. One end of the second spring 609 abuts against the dial 601, and the other end abuts against the stop block on the frame 401. When the movable block 605 pushes the dial 601 to slide in the cutting direction, the dial 601 compresses the second spring 609 at the same time, so that the second spring 609 stores elastic potential energy. When the movable block 605 rises and disengages from the dial 601, the second spring 609 releases its elastic potential energy, pushing the dial 601 and the scriber 602 to slide back to their initial positions in the opposite direction, preparing for the next cut.

[0038] The entire cutting process is completed by mechanical moving parts, without involving any electrical components such as solenoid valves, sensors or controllers, and has excellent reliability and durability in an environment filled with spray water mist.

[0039] VII. Structural Composition and Length Adaptation Principle of the Feeding and Discharging System Reference Figure 10 The bottom of the water tank 100 is equipped with an automatic feeding and discharging mechanism, which consists of multiple sets of feeding and discharging units arranged at intervals along the axial direction of the cement rod 800 (in this embodiment, three sets are set, labeled 700a, 700b, and 700c respectively); each set of feeding and discharging units adopts the same structural design, and is installed independently but works in concert.

[0040] Taking one set as an example: it includes a base 700 fixedly installed at the bottom of the water tank 100. A vertical guide tube 701 is welded and fixed on the base 700. The guide tube 701 is hollow inside to accommodate the rack 702 and provide it with lifting guidance. The tooth surface of the rack 702 faces outward and can slide up and down along the inner wall of the guide tube 701. A mounting seat 703 is fixedly installed on the outer side of the upper end of the guide tube 701. A dual-axis motor 704 is fixed on the mounting seat 703. The two output shafts of the dual-axis motor 704 extend from both sides of the motor. A spur gear 705 is installed at the end of each output shaft. The two spur gears 705 mesh with the tooth surfaces on both sides of the rack 702. The top end of the rack 702 extends from the upper end of the guide tube 701 and is fixedly connected to a U-shaped frame 706. The opening of the U-shaped frame 706 faces upward. A roller 707 is rotatably installed between its two side walls. The axial direction of the roller 707 is consistent with the axial direction of the cement pole 800.

[0041] Each set of dual-axis motors 704 in the feeding and discharging units is equipped with an independent driver, which can be started and stopped by the main control system of the equipment. When a set of dual-axis motors 704 receives a start signal, the motor output shaft drives the spur gear 705 to rotate. The spur gear 705 drives the rack 702 to slide up or down along the guide tube 701 through tooth meshing, thereby pushing the U-shaped frame 706 and the idler roller 707 to rise and fall.

[0042] In actual production, cement poles 800 of different specifications have different lengths. The control system automatically determines which sets of feeding and discharging units need to be activated based on the length parameters of the cement pole 800 to be processed. For shorter poles, activating only one or two sets in the middle position is sufficient to provide adequate support, while the feeding and discharging units at both ends remain stationary to avoid unnecessary energy consumption and mechanical movements. For longer poles, all units are activated simultaneously, so that each roller 707 is evenly distributed along the entire length of the cement pole, sharing the weight of the pole from multiple support points, and preventing the long pole from bending and deforming due to its own weight during the lifting process.

[0043] During feeding, the operator or feeding device places the cement rod 800 on each idler roller 707. The control system then activates the selected feeding and discharging units to descend synchronously, placing the cement rod 800 smoothly on the support roller 107. During unloading, each selected feeding and discharging unit rises synchronously, lifting the cement rod 800 from the support roller 107. Subsequently, the discharging device rolls the rod along the idler roller 707 and moves it out of the water tank 100. The independent control design of each feeding and discharging unit allows the equipment to adapt to the production needs of cement rods of various lengths without changing the main structure, significantly enhancing the versatility and flexibility of the equipment.

[0044] VIII. Overall Equipment Operation Flow The operation process of the cement pole curing equipment of the present invention in actual production is as follows: Material feeding stage: According to the length of the cement pole to be cured, the control system selects the corresponding number and position of the feeding and discharging units, drives their rollers 707 to rise to an appropriate height; the cement pole 800 is hoisted or rolled onto each roller 707, and then the feeding and discharging units are controlled to descend synchronously, so as to smoothly transfer the cement pole 800 onto the support roller 107.

[0045] Spray curing stage: Start the first motor 106 to drive the roller 105 and the support roller 107 to rotate, causing the cement pole 800 to rotate around its own axis at a set speed; at the same time, start the water pump and the second motor 201. The water pump delivers curing water to the arc-shaped pipe 300 and atomizes it through each nozzle 301. The second motor 201 drives the reciprocating screw 200 to rotate, causing the arc-shaped pipe 300 and the nozzles 301 to move back and forth along the axial direction of the cement pole 800; during this stage, the brush 304 continuously scrubs the rotating pole surface, and the elastic scraper 305 then spreads the water film evenly; the curing time is set according to the specifications and process requirements of the cement pole.

[0046] Covering stage: After spray curing is completed, the end of the curing film on the film rolling roller 402 is led out, passes through the gap between the transition roller 403 and the two pressure rollers 405, and is pulled out from the outlet of the film outlet 404 and attached to the surface of the cement pole 800; the cement pole 800 continues to rotate, and the toothed wheel 407 is driven to rotate by friction, which in turn drives the pressure roller 405 to continuously output the curing film; the pressure rod 501 presses the film material against the pole surface under the action of gravity and removes air bubbles, and the cam 503 applies intermittent clamping force with the reciprocating motion of the arc tube 300; as the cement pole 800 rotates several times, the curing film completely covers the surface of the pole.

[0047] Automatic cutting stage: After the film coating is completed, the reciprocating motion of the arc tube 300 triggers the guide tube 603-moving block 605 assembly to move the scriber 602 to cut the curing film laterally; during the return stroke, the moving block 605 is automatically lifted and disengaged by the inclined rail 608, and the second spring 609 resets the scriber 602; the cutting process is completed automatically, and the end of the film material is neatly left at the outlet of the film outlet 404, waiting for the next film coating.

[0048] Material feeding stage: The control system restarts the selected feeding and discharging units to rise synchronously. The idler roller 707 lifts the cured cement rod 800 from the support roller 107. The discharge device moves the rod out of the water tank 100 along the idler roller 707 and transfers it to the stockyard or the next process.

[0049] Example 1

[0050] The maintenance equipment provided by this invention is used to maintain a batch of cement poles of conventional specifications, which are commonly used in power transmission and distribution lines.

[0051] Based on the length parameters of the batch of rods, the equipment control system automatically selects all three sets of feeding and discharging units to participate in the work; during feeding, the three sets of dual-shaft motors 704 rotate synchronously in the forward direction, and each rack 702 drives the idler rollers 707 to rise to the highest position, and the cement rods 800 are hoisted by the overhead crane onto the three sets of idler rollers 707; then the three sets of dual-shaft motors 704 rotate synchronously in the reverse direction, the idler rollers 707 descend, and the cement rods 800 are placed stably on the support rollers 107 of the two rollers 105.

[0052] The first motor 106 is started, which drives the roller 107 to rotate the cement pole 800 at a set speed via the roller 105; the water pump is started, which pressurizes the curing water in the water tank 100 to a set pressure and delivers it to the arc-shaped pipe 300, and each nozzle 301 sprays water onto the pole surface in the form of a fan-shaped mist; the second motor 201 drives the reciprocating screw 200 to run at a set speed, and the reciprocating stroke of the arc-shaped pipe 300 covers the entire length of the cement pole 800; during the spraying process, the brush 304 removes the laitance from the pole surface, and the elastic scraper 305 smooths the water film; after the spraying curing continues for a set time, the pole surface reaches a fully moistened state.

[0053] The process then transitions to film coating. The operator pulls out the polyethylene film from the film winding roller 402, passes it through the gap between the transition roller 403 and the pressure roller 405, pulls it out to a set length from the outlet of the film nozzle 404, and attaches it to the surface of the rotating cement rod 800. The rotational motion of the cement rod 800 drives the toothed wheel 407 to rotate, and through belt drive, the pressure roller 405 continuously outputs film at a matching linear speed. As the cement rod 800 rotates a set number of times, the film overlaps and covers the rod surface. The pressure rod 501 presses the film surface under gravity, expelling air bubbles to both sides. The cam 503 reciprocates with the arc-shaped tube 300, applying additional pressure each time it passes a set of pressure rods 501, helping the film material to adhere further.

[0054] When the film coating is nearly completed, the arc tube 300 moves to the end where the film outlet 404 is located. The guide tube 603 drives the movable block 605 to push the pusher 601. The scriber 602 slides laterally in the cutting groove 4041 to cut the film in one go. Then the arc tube 300 moves in the opposite direction. The fixed rod 606 rises along the inclined rail 608 to lift and disengage the movable block 605. The second spring 609 pushes the scriber 602 to reset. The cut film is neatly left at the outlet of the film outlet 404.

[0055] Finally, each set of dual-shaft motors 704 rotates synchronously in the forward direction, the rollers 707 rise and push the cement rods 800 away from the rollers 107, and the operators roll the rods along the rollers 707 to the conveyor roller track at the end of the water tank 100 to complete the unloading. Example 2

[0056] The curing equipment provided by this invention was used to cure another batch of slender cement poles. These poles have a large length-to-diameter ratio and require higher stability of support and uniformity of spraying.

[0057] Due to the large length of the rod, the control system also selects all feeding and discharging units to participate in the operation, ensuring that multiple support points are evenly distributed along the length of the rod, and preventing the slender rod from bending and deforming due to its own weight during the lifting process; in addition, because the rod diameter is small, by controlling the telescopic rod of the first cylinder 104 to retract a certain stroke, the mounting frame 102 deflects downward around the hinge point of the support rod 101, and the arc-shaped tube 300 moves closer to the surface of the cement rod 800, so that the distance between each nozzle 301 and the rod surface is kept in the optimal spraying range.

[0058] Regarding the spraying parameters, since the rotational inertia of small-diameter rods is relatively small, the driving speed of the support roller 107 is appropriately increased so that the rod surface can receive more spray coverage times in the same amount of time; the water pump pressure is adjusted accordingly to avoid uneven water film flow caused by high-pressure water mist impacting the surface of the slender rod; the stroke of the reciprocating screw 200 is adjusted according to the rod length to ensure that the arc-shaped tube 300 covers the entire length of the rod.

[0059] During the film laying stage, due to the small rod diameter, the height of the film outlet 404 needs to be manually fine-tuned to ensure that the direction of the film material's lead-out is tangent to the rod surface at the bonding point, thus preventing wrinkles in the film material. As the rod diameter decreases, the swing angle of the pressure rod 501 increases accordingly, and its end can still naturally press against the film surface without adjustment. During the reciprocating movement of the cam 503 with the arc tube 300, it drives each pressure rod 501 to generate periodic small-amplitude vibrations through the connecting plate 502. For the surface of slender rods, this vibration compaction effect is particularly obvious, which helps the film material to adhere tightly to the rod surface with a large curvature.

[0060] The lamination and cutting process is the same as in Example 1. When feeding, attention should be paid to the stability of the slender rod. Each set of dual-axis motors 704 rises slowly and synchronously. The lifting speed of the rod is controlled within a low range by the rollers 707 to prevent the rod from shaking due to excessive speed. After discharge, check the lamination quality. The film surface is flat and wrinkle-free, and the rod end is neatly covered with film.

[0061] The remaining operating steps are the same as in Example 1, and will not be repeated here.

[0062] Example 3

[0063] The curing equipment provided by this invention was used to cure another batch of short and thick cement poles. These poles are short in length but heavy in weight.

[0064] Based on the length information of the rods in this batch, the control system selects to start only one set of feeding and discharging units located in the middle position. Because the weight of the short rods is concentrated in the central area, the middle set of rollers can effectively lift them, while the units at both ends remain stationary. The power of this set of dual-axis motors 704 is sufficient to bear the weight of rods of this specification, and there is no need for multiple sets to be connected in parallel. The selective start mode saves most of the power consumption and reduces the frequency of mechanical actions.

[0065] Regarding the spraying parameters, due to the shorter rod, the stroke of the reciprocating screw 200 driven by the second motor 201 is limited to the corresponding range, and the reciprocating frequency of the arc tube 300 is higher than that of Example 1; the rotational speed of the support roller 107 driven by the first motor 106 is maintained at the set value. Due to the larger rod diameter and weight, the rotational inertia is sufficient, and a lower rotational speed can ensure the uniformity of the spray coverage.

[0066] During the film laying stage, due to the short length of the pole, the cement pole only needs to rotate a few times to complete the full coverage in one film covering operation; the amount of film material consumed on the film rolling wheel 402 is reduced accordingly; the cycle of the cam 503 moving back and forth with the arc tube 300 is matched with the short pole, and the pressing action of the pressure rod 501 covers the entire length of the pole.

[0067] As described above, during the cutting stage, the movable block 605 pushes the pusher 601 to trigger the scriber 602 to cut the membrane material, and the reset mechanism remains unchanged.

[0068] During material feeding, only the dual-axis motor 704 of the middle set of feeding and discharging units is started. The roller 707 lifts the short rod from the middle, keeping both ends suspended but not bending due to gravity (because the rod is short and has sufficient rigidity). After material discharge, the short rod rolls out along the roller 707 to complete the operation.

[0069] The remaining details are the same as in Example 1, and will not be repeated here.

[0070] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
