Description

Technical Field

[0001] The present invention relates to the technical field of cement pole spraying, and specifically to an integrated equipment for preparing and spraying an environment-friendly anti-corrosion coating for cement poles. Background Art

[0002] Cement poles are indispensable infrastructure in the power transmission system. They bear the weight of power equipment and conductors as well as wind and rain erosion. Therefore, anti-corrosion is a very important part in the manufacturing process of cement poles. Usually, the spraying method or roller coating method is adopted, and attention should be paid to the quality of the coating and the thickness of the coating. Too thick a coating will affect durability and adhesion, while too thin a coating will reduce the anti-corrosion effect.

[0003] During the construction process, construction should be avoided in environments with strong wind, high temperature and high humidity to avoid affecting the drying speed and construction quality of the coating. In addition, since the cement pole is cylindrical, there will inevitably be a sag phenomenon after spraying, resulting in uneven surfaces and affecting the anti-corrosion ability of the cement pole.

[0041] Please refer to Figures 1-12As shown in the figure, the present invention provides an integrated equipment for the preparation and spraying of an environment-friendly anti-corrosion coating for cement poles, including a feeding tank 100 for stirring and preparing anti-corrosion coatings. A stirring rod is horizontally installed inside the bottom of the feeding tank 100, and a stirring motor 160 is coaxially connected to the outer end of the stirring rod. The anti-corrosion coating preferably uses an acrylic coating, which is prepared by mixing acrylic emulsion, curing agent, diluent and water in appropriate proportions. This is prior art and will not be elaborated here. A number of blades are welded on the outer side of the stirring rod to quickly stir the anti-corrosion coating evenly. A spraying group 200 is arranged at the bottom of the front side of the feeding tank 100. A feeding table 110 for feeding cement poles into it is arranged outside one end of the spraying group 200. The cement pole is lifted by a gantry crane and placed on the feeding table 110, and then horizontally transported to the spraying group 200 for circumferential spraying on the outer side of the cement pole.

[0042] A feeding group 300 for hanging and transporting the cement pole and smoothing the sag on the bottom surface of the pole is arranged outside the other end of the spraying group 200. Since the cement pole is cylindrical, sag is inevitable after spraying, resulting in uneven surface. Therefore, by setting the feeding group 300, while feeding, the coating on the lower half of the pole is smoothed to solve the above problems.

[0043] Specifically, a nozzle 101 and a feeding hole 102 are arranged on the top of the feeding tank 100. A suction pump 130 is installed on the feeding hole 102, and a number of liquid distribution pipes 120 are installed at the output end of the suction pump 130. The spraying group 200 includes a spraying pipe 210 corresponding to the lower ends of a number of liquid distribution pipes 120 in a sleeved manner, and a number of nozzles 220 embedded inside the annular spraying pipe 210. The nozzles 220 are prior art and will not be elaborated here. In addition, by setting the diameters of the nozzles 220 on a number of spraying pipes 210 to gradually decrease, multiple layers of spraying are formed on the surface of the cement pole, and the spraying amount of each layer gradually decreases, that is, the spraying amount of the inner layer is large and can adsorb and adhere to the surface of the inner pole. When spraying the outer layer, due to the small amount, the rapid sag phenomenon of the coating is controlled.

[0044] The top of the spraying pipe 210 is disconnected and sealed to facilitate the smooth passage of the lifting rope of the gantry crane. A through hole for plugging and matching with the liquid distribution pipe 120 is opened in the middle of the bottom surface of the spraying pipe 210, so that the coating is split from the middle of the bottom of the spraying pipe 210 to both sides, ensuring the uniform spraying amount of the nozzles 220. A number of idler rollers 140 are embedded between the inner walls of the feeding table 110. A feeding motor 150 for driving a number of idler rollers 140 to rotate is installed on the side wall of one end of the feeding table 110. By sleeving conveyor belts between the two ends of a number of idler rollers 140 to play a role of synchronous movement, the cement pole placed on the feeding table 110 is smoothly transported.

[0045] Further, the liquid separation pipe 120 is L-shaped and a liquid separation plate 121 is embedded at its lower port for separating the volume of the port of the liquid separation pipe 120, so as to separate the sprayed coating; a straight pipe inserted into the feeding hole 102 is sleeved at the feeding end of the suction pump 130, and the straight pipe extends above the bottom of the feeding tank 100. A horizontal pipe is sleeved on the upper ends of several liquid separation pipes 120, and the top of the horizontal pipe is inserted and matched with the elbow pipe arranged at the output end of the suction pump 130.

[0046] Further, a support frame 230 is welded between several spraying pipes 210. The support frame 230 is annular and has an open top. The bottom of the support frame 230 is supported and fixedly connected to the bottom of the feeding tank 100 through a flat plate;

[0047] Several nozzles 220 are arranged at equal intervals in a ring. The outer diameter of the middle part of the idler roller 140 is smaller than that of its two ends, and the central axis position of the idler roller 140 is higher than that of the nozzles 220 at the bottom of the spraying pipe 210. The inner diameter of the circle formed by several nozzles 220 is larger than the large diameter end of the cement pole, so that the cement pole on the idler roller 140 can smoothly penetrate into the central axis of the spraying pipe 210 for movement and be evenly sprayed.

[0048] Specifically, the feeding group 300 includes a pair of feeding frames 310, several feeding belts 320 sleeved between the pair of feeding frames 310, and several hanging groups 330 suspended side by side below the feeding belts 320; one end of the feeding frame 310 is arranged in horizontal alignment with the end of the spraying pipe 210, and a row of several hanging groups 330 is arranged coaxially with the spraying pipe 210, so that the sprayed cement pole can smoothly penetrate into the hanging group 330 and be suspended;

[0049] A feeding motor 311 for driving several feeding belts 320 to circulate is installed at one end of the feeding frame 310, so as to convey the cement pole to the other end of the feeding frame 310 for unloading; the hanging group 330 includes an upper hanging part 331 and a lower hanging part 332 hinged together and several coating spreading wheels 333 embedded in the inner wall of the lower hanging part 332; the upper hanging part 331 and the lower hanging part 332 form an open ring structure and its central axis is coaxially arranged with the central axis of the spraying pipe 210, that is, the cement pole is supported by the lower hanging part 332; at the same time, several coating spreading wheels 333 rollingly contact the lower half of the cement pole to smear the coating evenly and eliminate the sagging situation.

[0050] Further, a round shaft is sleeved between the two ends of the pair of feeding frames 310, and one end of the round shaft is coaxially connected with the feeding motor 311. The feeding belt 320 is sleeved and matched with the pair of round shafts. The feeding belt 320 is made of rubber and stainless steel sheets are bonded to its upper and lower sides to increase its tensile strength; several hanging rods 321 are inserted through the sides of several feeding belts 320 at equal intervals, so that several feeding belts 320 are connected as a whole and move, increasing the strength of hanging the cement pole and preventing the feeding belt 320 from sagging significantly;

[0051] The top of the upper hanging member 331 is provided with a collar 3311 that is closely sleeved on the hanging rod 321; on the outer side of the hinge joint of the upper hanging member 331 and the lower hanging member 332, there is a spring pressing piece 334. The spring pressing piece 334 is in the shape of an arc piece and has the same central axis as the upper hanging member 331 and the lower hanging member 332. The spring pressing piece 334 is made of spring steel into a sheet shape, so that it has elasticity and rebounds to reset the lower hanging member 332. Since the gravity exerted by the cement pole on the lower hanging member 332 is along the tangent direction of the hinge joint of the upper hanging member 331 and there is no lateral acting force, plus the rebounding force of the spring pressing piece 334, the upper hanging member 331 will stably suspend the lower hanging member 332 to form a supporting state.

[0052] When the hanging material group 330 holds the cement pole and is conveyed to the bending at the discharge end of the feeding frame 310, since the upper hanging member 331 moves through the bend along with the conveyor belt 320, the tangent direction of its hinge joint becomes horizontal. Therefore, the gravity of the cement pole presses down the lower hanging member 332 and bends it with the upper hanging member 331, and then the cement pole smoothly rolls out from the opening between the upper hanging member 331 and the lower hanging member 332. After that, the lower hanging member 332 resets under the action of the rebounding force of the spring pressing piece 334.

[0053] Furthermore, clamping blocks 3312 are provided on the outer side walls of the upper hanging member 331 and the lower hanging member 332 and close to the hinge ends. The cross sections of the two clamping blocks 3312 are in an L shape and are symmetrically arranged. The upper and lower ends of the spring pressing piece 334 are clamped and matched with a pair of clamping blocks 3312, and there is a gap between the upper and lower ends to facilitate the bending deformation of the spring pressing piece 334.

[0054] Furthermore, the plastering wheel 333 is composed of a short shaft and a pair of rubber sleeves sleeved outside it. The two ends of the rubber sleeve are in the structure of a round roller with one large and one small diameter, so as to contact the cement pole over a large area for plastering. A ring sleeve 336 is sleeved in the middle of the short shaft of the plastering wheel 333, and a ring block 335 whose bottom is welded with a central shaft and is vertically arranged horizontally with it is provided at the bottom of the ring sleeve 336.

[0055] The lower hanging member 332 is in a semi-circular ring structure, and a number of V-shaped positioning grooves 3321 are equally spaced on its inner arc surface. Conical avoidance grooves 3322 are provided on both sides of the positioning grooves 3321. The ring block 335 is rotatably connected with the positioning grooves 3321 through pins, so that the ring block 335 can swing and automatically press against the cement pole. The end of the plastering wheel 333 is clamped with the avoidance grooves 3322, so that the plastering wheel 333 is not interfered by the inner arc surface of the lower hanging member 332 when swinging.

[0056] In addition, in order to protect the coating on the surface of the cement pole and to stack and store it after drying, a drying group 400 is arranged below the discharge end of the feed rack 310. The drying group 400 includes a downwardly inclined collecting rack 410, a retaining wall 420 fixedly arranged at the lower end of the collecting rack 410, and supporting wheels 430 rollingly connected to the collecting rack 410; the supporting wheels 430 are sleeved and matched with the two ends of the cement pole; when the cement pole is transported to the intersection of the feed rack 310 and the collecting rack 410, the two supporting wheels 430 are inserted into the two ends of the cement pole until the cement pole rolls out of the lower hanging part 332 and falls onto the collecting rack 410, and a pair of supporting wheels 430 rolls along its inclined surface to the retaining wall 420 and stops to wait for drying, and then the cement pole is lifted away by a traveling crane and stored at a selected location.

[0057] Specifically, a guide rail 411 is embedded on the top surface of the material collecting rack 410 and along its inclined direction, and a wheel groove 431 for engaging and rolling with the guide rail 411 is opened in the middle of the supporting wheel 430, and the two side surfaces of the wheel groove 431 are in an outwardly inclined state so as to engage and roll with the guide rail 411, thereby ensuring that the cement pole is supported and rolled to the lower end of the material collecting rack 410; a sleeve shaft 432 matching the end hole of the cement pole is coaxially welded at one end of the supporting wheel 430, thereby ensuring that a pair of supporting wheels 430 coaxially support the cement pole and roll smoothly.

[0058] When the integrated equipment for preparing and spraying the environment-friendly anti-corrosion coating of the cement pole of the present invention is working, the raw materials of the anti-corrosion coating are injected into the feed box 100 for stirring and mixing, and then the cement pole is placed on the feed platform 110 for transportation. When the cement pole enters the stinger rack 230, the suction pump 130 is started to pump the anti-corrosion coating liquid in the feed box 100 into a plurality of spray pipes 210, and sprayed out through a plurality of nozzles 220, thereby forming a multi-layer spray coating layer on the surface of the cement pole; after the cement pole is transported to the bottom of one end of the feed rack 310, it is supported by a plurality of hanging groups 330, and a plurality of smearing wheels 333 are in rolling contact with the lower half of the cement pole to evenly spread the coating and eliminate sagging;

[0059] At the same time, cement poles to be sprayed are continuously placed on the feeding platform 110, so that all the previously sprayed cement poles are pushed to the bottom of the feeding frame 310; at this time, the feeding motor 311 is started again to drive the plurality of feeding belts 320 to circulate, and the plurality of rows of hanging material groups 330 carry the sprayed cement poles to the discharge end of the feeding frame 310;

[0060] When the cement pole is transported to the intersection of the feed rack 310 and the collecting rack 410, two supporting wheels 430 are inserted into the two ends of the cement pole until the cement pole rolls out of the lower hanging part 332 and falls onto the collecting rack 410. The pair of supporting wheels 430 rolls along the inclined surface to the retaining wall 420 and stops to wait for drying. Then the cement pole is lifted away by a crane and stored at a selected location.

[0061] It should be noted that the above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. However, it should not be used to limit the protection scope of the present invention.
