Description

Technical Field

[0001] The invention relates to the technical field of electric pole casting, in particular to an electric pole casting system and a casting method suitable for continuous production. Background Art

[0002] The pouring of electric poles is divided into two major links: prefabricated pole production and on-site foundation construction, which need to take into account the materials, processes and environmental adaptability. The process flow of prefabricated poles includes: steel cage production, using a combination of automatic welding and manual binding, inserting tension bars and fixing anchor points, mold assembly, mechanically stretching the tension bars to the design value and then closing the mold, centrifugal pouring, rotary grouting to ensure the compactness of the concrete, and then homogenizing and forming it through a centrifuge, steam curing, and high temperature and high humidity environment to accelerate the hardening of concrete and improve early strength. On-site construction is divided into two types of foundations: buried depth and flange. The buried depth foundation needs to excavate the foundation pit according to 1 / 5 to 1 / 6 of the pole length, fill in mortar, concrete and masonry in layers, and pre-embed the chassis and chuck to enhance the anti-overturning performance. The flange foundation is connected to the pole body by pre-embedded flange bolts to simplify complex geological construction. Special areas need to be supplemented with reinforcement measures, such as using steel strands to disperse tension in mountainous areas and using the injection method to enhance foundation stability in wetlands.

[0003] However, in combination with actual work, we found that the existing casting of electric poles requires first wrapping a steel bar ring around multiple strip steel bars to form a steel bar frame, placing the steel bar frame inside a mold, then pouring concrete into the mold, rotating the mold to dehydrate it, and allowing the concrete to evenly fit the steel bar frame, and then drying and demolding to complete the casting of the electric pole. However, the concrete includes cement liquid and sand and gravel, among which the sand and gravel have a large volume. When the density of the steel bar ring is small, the sand and gravel may not be able to pass through the steel bar ring and flow to the outer surface of the steel bar ring, thus causing the problem of slightly lower strength of the electric pole.

[0031] The present invention also provides a pouring method for a pouring system of utility poles suitable for continuous production, including the following steps:

[0032] Drive the hydraulic cylinder to insert into the mold through the hydraulic rod. Subsequently, push the semi-circular sleeve, spherical ball, and cylinder to slide downward through the hydraulic cylinder. The cylinder drives the connecting plate and the elastic band to slide downward. At this time, spray concrete towards the connecting plate through the auger pipe. In this way, limit the lower end of the connecting plate through multiple elastic bands to spray concrete;

[0033] Swing the cylinder to one side or the other, so that the cylinder drives the connecting plate and the connecting bar to swing to one side or the other. The hydraulic cylinder is at the axis of the steel bar ring. Therefore, the connecting bar will slide along the diameter of the steel bar ring. In this way, use the connecting bar at the changed position to expand the steel bar ring, so that the sand and gravel in the concrete can fill the outside and inside of the steel bar ring;

[0034] Control the expansion of the left arc-shaped pipe through two positioning devices, and control the expansion of the right arc-shaped pipe through the other two. In this way, when the piston plate of the left positioning device is pulled by the steel cable, it means that the elasticity of the left steel bar ring is relatively large, and the two connecting bars on the left cannot expand the steel bar ring. At this time, the liquid inside the piston plate of the left positioning device will be transmitted to the guiding device at the left arc-shaped pipe, so that pure water fills the arc-shaped pipe. In this way, expand the left arc-shaped pipe to drive the connecting plate to swing to the right, so as to realize automatically sensing the spring ring limit and automatically adjusting the position of the connecting plate;

[0035] Use the pure water to impact and open the limit plug, so that the pure water enters the circulation cavity and the first hose. Transmit the pure water to the connecting bar through the first hose, and spray the pure water through the connecting bar, so as to wash the concrete inside the mold, so that a large amount of sand and gravel can fall between the outer surface of the steel bar ring and the inner wall of the mold.

[0036] The present invention has the following beneficial effects:

[0037] 1. For the pouring system of utility poles suitable for continuous production, use two connecting bars to insert into the steel bar ring. In this way, use four connecting bars to expand the steel bar ring, so that the lower end of the connecting plate can spray the concrete containing sand and gravel between the outer surface of the steel ring and the mold. In this way, realize that the concrete with sand and gravel fully fills the outside and inside of the steel bar ring, thereby improving the strength of the utility pole.

[0038] 2. For the pouring system of utility poles suitable for continuous production, swing the cylinder to one side or the other, so that the cylinder drives the connecting plate and the connecting bar to swing to one side or the other. The hydraulic cylinder is at the axis of the steel bar ring. Therefore, the connecting bar will slide along the diameter of the steel bar ring. In this way, use the connecting bar at the changed position to expand the steel bar ring, so that the sand and gravel in the concrete can further fill the outside and inside of the steel bar ring.

[0039] 3. The pole casting system applicable to continuous production transmits liquid to the second chamber and the first chamber through the third hose, thereby pushing the bolt and the sliding plate to slide to the left, making the bolt abut against the limit plug to seal one end of the flow chamber, and at the same time the sliding plate will drive the square groove to communicate with the inside of the arc-shaped pipe. In this way, by transmitting pure water to the first hole, the pure water enters the second hole through the square groove through the first hole, thereby expanding the second hole, and the expanded second hole pushes the connecting plate to move, thus changing the position of the connecting plate.

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0049] The invention technology involved in this application is summarized and designed based on projects such as the project of producing 60,000 cement poles and 1,000 cubic meters of cement pole accessories per year, the project of agency storage and sales of poles by the coking coal power supply department, and the first supplementary public bidding procurement project for distribution network material agreement inventory of State Grid Henan Electric Power Company in 2024. During the production and delivery of the above projects, when pouring the electric poles, due to the coexistence of cement slurry and sand and gravel in the concrete, where the volume of sand and gravel is relatively large, when the density of the steel wire rings is relatively small, the sand and gravel cannot flow through the steel wire rings to the outer surface of the steel wire rings, which will cause the problem of low strength of the electric poles. Therefore, as an innovative small and medium-sized enterprise, through continuous technological updates, we have proposed a pouring system and pouring method for electric poles applicable to continuous production, aiming to enable the sand and gravel in the concrete to better fill the outside and inside of the steel wire rings, improve the strength of the electric poles, and achieve automatic adjustment with convenient operation, achieving the expected good results.

[0050] Embodiment 1

[0051] Please refer to Figure 1 - Figure 2 , a pouring system for electric poles applicable to continuous production, comprising:

[0052] A hydraulic rod 1, and a screw conveyor pipe 2 is installed at the lower end of the hydraulic rod 1;

[0053] A hydraulic cylinder 3, and the hydraulic cylinder 3 is installed at one end of the hydraulic rod 1;

[0054] A connecting device 4, and the connecting device 4 is installed at the lower end of the hydraulic cylinder 3, and the hydraulic cylinder 3 is used to control the sliding of the connecting device 4;

[0055] The connecting device 4 includes a semi-circular sleeve 41 connected to the lower end of the hydraulic cylinder 3, a spherical ball 42 is rotatably connected inside the semi-circular sleeve 41, and a cylinder 43 is installed at the lower end of the spherical ball 42;

[0056] An adjusting device 5, the adjusting device 5 includes a connecting plate 51, a rotating shaft 52, a connecting strip 53 and a spray hole 54, the upper end of the connecting plate 51 is connected to the lower end of the cylinder 43, two rotating shafts 52 are arranged on both sides of the connecting plate 51, both ends of the rotating shaft 52 are rotatably connected with a connecting strip 53, an elastic band 55 is arranged between every two connecting strips 53, and a spray hole 54 for spraying liquid is further arranged at the lower end of the connecting strip 53.

[0057] Existing pole casting requires first winding a steel bar ring around multiple strip-shaped steel bars on one side to form a steel bar framework, placing the steel bar framework inside a mold, then pouring concrete into the mold, then rotating the mold to dehydrate, and allowing the concrete to evenly adhere to the steel bar framework, and then drying and demolding to complete the pole casting. However, the concrete includes cement liquid and sand and gravel. Among them, the sand and gravel have a relatively large volume. When the density of the steel bar ring is relatively small, the sand and gravel may not be able to flow through the steel bar ring to the outer surface of the steel bar ring, so it will cause the problem of slightly lower strength of the pole;

[0058] According to Figure 1 and Figure 2 As shown, the hydraulic rod 1 drives the hydraulic cylinder 3 to insert into the mold. Then, the hydraulic cylinder 3 pushes the semi-circular sleeve 41, the spherical ball 42, and the cylinder 43 to slide downward. The cylinder 43 drives the connecting plate 51 and the elastic band 55 to slide downward. At this time, concrete is sprayed towards the connecting plate 51 through the auger pipe 2. In this way, the lower end of the connecting plate 51 is limited by multiple elastic bands 55 to spray concrete;

[0059] Then, continue to push the connecting plate 51 and the connecting bar 53 downward through the hydraulic cylinder 3. According to Figure 2 , the extension lines of the two connecting bars 53 form an acute angle. Therefore, the two connecting bars 53 are used to insert into the steel bar ring. In this way, the four connecting bars 53 are used to expand the steel bar ring, so that the lower end of the connecting plate 51 can spray the concrete containing sand and gravel between the outer surface of the steel ring and the mold. In this way, it is realized that the concrete with sand and gravel fully fills the outside and inside of the steel bar ring, thereby improving the strength of the pole;

[0060] Furthermore, since multiple steel bars penetrate the steel bar ring, the area where the steel bar ring can be expanded is relatively small. Therefore, when the hydraulic cylinder 3 pushes the connecting bar 53 downward, the connecting bar 53 may not be able to expand the steel bar ring. Therefore, it is necessary to change the position of the connecting bar 53. According to Figure 2 As shown, by swinging the cylinder 43 to one side or the other, the cylinder 43 drives the connecting plate 51 and the connecting bar 53 to swing to one side or the other. The hydraulic cylinder 3 is at the axis of the steel bar ring. Therefore, the connecting bar 53 will slide along the diameter of the steel bar ring. In this way, the connecting bar 53 with the changed position is used to expand the steel bar ring, so that the sand and gravel in the concrete can fill the outside and inside of the steel bar ring.

[0061] Embodiment 2

[0062] This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figure 1 - 2 , in this embodiment, the connecting device 4 further includes a first elastic sheet 44 and an arc-shaped pipe 45. One end of the first elastic sheet 44 is connected to one end of the hydraulic cylinder 3, and the other end of the first elastic sheet 44 is connected to one end of the cylinder 43;

[0063] One end of the arc tube 45 is connected to one end of the hydraulic cylinder 3, and the other end of the arc tube 45 is connected to one end of the cylinder 43;

[0064] The upper end of the arc tube 45 is communicated with the interior of the auger tube 2 .

[0065] according to Figure 2 As shown, by filling the arc tube 45 with liquid, the arc tube 45 is expanded. Since the arc tube 45 is arc-shaped, the expanded arc tube 45 squeezes the cylinder 43 to swing to one side, thereby pushing the cylinder 43 and the connecting plate 51 to swing to one side, thereby adjusting the position of the connecting plate 51 and the connecting strip 53, so that the connecting strip 53 can adjust its position to open the steel ring.

[0066] Example 3

[0067] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1 - 6 In this embodiment, the adjustment device 5 further includes an extension frame 56, a limiting wheel 57 and a steel cable 58. The extension frame 56 and one end of the steel cable 58 are connected to the lower end of the hydraulic cylinder 3. Both sides of the extension frame 56 are rotatably connected to the limiting wheel 57. The other end of the steel cable 58 is attached to the outer surface of the limiting wheel 57 and connected to one end of the connecting bar 53.

[0068] A positioning device 6 is installed at one end of the connecting strip 53. The positioning device 6 includes a round sleeve 61 installed at one end of the connecting strip 53. A piston plate 62 is slidably connected inside the round sleeve 61. The piston plate 62 divides the inside of the round sleeve 61 into a first cavity and a second cavity.

[0069] A guide post 64 is installed at one end of the piston plate 62, and the guide post 64 passes through the circular sleeve 61. One end of the steel cable 58 is connected to one end of the guide post 64.

[0070] The outer surface of the guide column 64 is provided with a protrusion 65, and the inner wall of the circular sleeve 61 is provided with a second elastic sheet 66, and the protrusion 65 is used to squeeze the second elastic sheet 66 to deform;

[0071] A second hose 67 is also installed on the upper end of the circular sleeve 61;

[0072] The piston plate 62 and the circular sleeve 61 are connected via a first spring 63;

[0073] A guide device 7 and a one-way valve 8 are installed inside the arc tube 45;

[0074] The upper end of the arc tube 45 is provided with a first hole 9 for receiving liquid, and the lower end of the arc tube 45 is provided with a second hole 10 for transmitting liquid to the connecting plate 51;

[0075] The guide device 7 includes an adjustment box 71 installed inside the arc tube 45, and the adjustment box 71 is provided with a first cavity 73, a second cavity 74 and a flow cavity 79 inside.

[0076] A slide plate 75 is slidably connected inside the first cavity 73. The slide plate 75 is used to block the inside of the arc tube 45. A square groove 76 is provided on the slide plate 75. The slide plate 75 is connected to the adjustment box 71 via a return spring.

[0077] A latch 77 is slidably connected inside the second cavity 74, and the latch 77 is connected to the adjustment box 71 via a second spring 70. One end of the latch 77 is slidably connected to the flow cavity 79, and the flow cavity 79 is also slidably connected to a limit stopper 78, and one end of the latch 77 is used to abut against the limit stopper 78.

[0078] A first hose 11 is installed at the upper end of the adjustment box 71, and the lower end of the first hose 11 is connected to the interior of the flow chamber 79;

[0079] A third hose 72 is also installed at one end of the adjustment box 71 . The third hose 72 is used to transfer liquid to the second cavity 74 and the first cavity 73 . The second hose 67 is used to transfer liquid to the third hose 72 .

[0080] according to Figure 4 and Figure 5 When the hydraulic cylinder 3 pushes the semicircular sleeve 41, the cylinder 43, the connecting plate 51 and the connecting strip 53 to slide downward, the steel cable 58 at the lower end of the hydraulic cylinder 3 pulls the positioning device 6 to move, and the positioning device 6 pulls the connecting strip 53 to unfold. The four connecting strips 53 are pulled to unfold by the four steel cables 58, so that the steel bar ring is opened by the unfolded connecting strips 53;

[0081] When the steel cable 58 pulls the positioning device 6 and the connecting strip 53 to unfold, the gap between the steel bar rings is close to the bar steel bar, so that the connecting strip 53 is limited by the elastic force of the steel bar ring, so that the steel cable 58 only pulls the piston plate 62 inside the round sleeve 61 to slide, so that the piston plate 62 is used to squeeze the liquid inside the round sleeve 61 to the second hose 67, and the liquid is transmitted to the third hose 72 through the second hose 67. Figure 6 , the liquid is transmitted to the second cavity 74 and the first cavity 73 through the third hose 72, thereby pushing the latch 77 and the slide plate 75 to slide to the left, so that the latch 77 contacts one end of the stopper 78 to seal the flow cavity 79, and at the same time the slide plate 75 drives the square groove 76 to communicate with the inside of the arc tube 45, so that the pure water is transmitted through the first hole 9, and the pure water enters the second hole 10 through the square groove 76 through the first hole 9, so as to expand the second hole 10, so that the expanded second hole 10 pushes the connecting plate 51 to move, and the position of the connecting plate 51 is changed;

[0082] It should be noted that according to Figure 2As shown, four positioning devices 6 are installed on the four connecting bars 53, two of which control the expansion of the left arc tube 45, and the other two control the expansion of the right arc tube 45. In this way, when the piston plate 62 of the left positioning device 6 is pulled by the steel cable 58, it means that the elastic force of the left steel bar ring is relatively large, and the two connecting bars 53 on the left cannot open the steel bar ring. At this time, the liquid inside the piston plate 62 of the left positioning device 6 will be transmitted to the guide device 7 at the left arc tube 45, so that the pure water fills the arc tube 45, thereby expanding the left arc tube 45 and driving the connecting plate 51 to swing to the right, thereby realizing automatic sensing of the spring ring limit and automatic adjustment of the position of the connecting plate 51;

[0083] It should be noted that the material of the elastic band 55 is elastic, so when the connecting strip 53 on one side swings to open the steel ring, and the connecting strip 53 on the other side cannot open the steel ring, the swinging connecting strip 53 will pull the elastic band 55 to extend;

[0084] It should be particularly noted that when the third hose 72 does not transmit liquid to the first cavity 73 and the second cavity 74, the pure water at the first hole 9 will be stored at the upper end of the slide plate 75, so that the pure water can be used to impact and open the limit plug 78, so that the pure water can enter the flow cavity 79 and the first hose 11, and the pure water can be transmitted to the connecting strip 53 through the first hose 11, and the pure water can be sprayed through the connecting strip 53 to flush the concrete inside the mold, so that a large amount of sand and gravel can fall between the outer surface of the steel ring and the inner wall of the mold.

[0085] Example 4

[0086] This embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1 - 7 In this embodiment, the one-way valve 8 includes a third hole 81 and a fourth hole 83 disposed inside the arc tube 45, and the third hole 81, the fourth hole 83 and the second hole 10 are connected;

[0087] The inner diameter of the third hole 81 is smaller than the inner diameter of the fourth hole 83, and the inner diameter of the fourth hole 83 is smaller than the inner diameter of the second hole 10;

[0088] A sliding disk 84 is slidably connected inside the fourth hole 83 and is used to seal the third hole 81 . A plug 82 is installed on the upper end of the sliding disk 84 and is slidably connected to the third hole 81 . The plug 82 is connected to the arc tube 45 via a third spring 85 .

[0089] according to Figure 7, when the arc-shaped pipe 45 is filled with pure water and expands, when the water pressure inside the arc-shaped pipe 45 is greater than the elastic force of the third spring 85, the water pressure will squeeze the plug column 82 and the sliding disc 84 to slide downward, so that the pure water inside the arc-shaped pipe 45 enters the second hole 10, and the high-pressure liquid is transmitted to the connecting strip 53 through the second hole 10, and the pure water is sprayed through the connecting strip 53, so as to wash the concrete inside the mold, so that a large amount of sand and gravel can fall between the outer surface of the steel ring and the inner wall of the mold.

[0090] The present invention also provides a pouring method for a pouring system of a telegraph pole suitable for continuous production, including the following steps:

[0091] Drive the hydraulic cylinder 3 to insert into the mold through the hydraulic rod 1, and then push the semi-circular sleeve 41, the spherical ball 42 and the cylinder 43 to slide downward through the hydraulic cylinder 3. The cylinder 43 drives the connecting plate 51 and the elastic belt 55 to slide downward. At this time, spray concrete towards the connecting plate 51 through the auger pipe 2, so as to spray concrete by limiting the lower end of the connecting plate 51 through a plurality of elastic belts 55;

[0092] Swing the cylinder 43 to one side or the opposite side, so that the cylinder 43 drives the connecting plate 51 and the connecting strip 53 to swing to one side or the other side. The hydraulic cylinder 3 is at the axis of the steel ring, so the connecting strip 53 will slide along the diameter of the steel ring, so as to use the connecting strip 53 in the changed position to expand the steel ring, so that the sand and gravel in the concrete can fill the outside and inside of the steel ring;

[0093] Control the expansion of the left arc-shaped pipe 45 through two positioning devices 6, and control the expansion of the right arc-shaped pipe 45 through the other two. So when the piston plate 62 of the left positioning device 6 is pulled by the steel cable 58, it means that the elastic force of the left steel ring is greater, and the two connecting strips 53 on the left cannot expand the steel ring. At this time, the liquid inside the piston plate 62 of the left positioning device 6 will be transmitted to the guiding device 7 at the left arc-shaped pipe 45, so that pure water fills the arc-shaped pipe 45, so as to expand the left arc-shaped pipe 45 and drive the connecting plate 51 to swing to the right, so as to realize automatic sensing of the spring ring limit and automatic adjustment of the position of the connecting plate 51;

[0094] Use the pure water to impact and open the limit plug 78, so that the pure water enters the flow cavity 79 and the first hose 11, transmit the pure water to the connecting strip 53 through the first hose 11, spray the pure water through the connecting strip 53, so as to wash the concrete inside the mold, so that a large amount of sand and gravel can fall between the outer surface of the steel ring and the inner wall of the mold.

10. A pouring method for a pouring system of utility poles suitable for continuous production, characterized in that, Including the following steps: Drive the hydraulic cylinder (3) to insert into the mold through the hydraulic rod (1). Then, push the semi-circular sleeve (41), the spherical ball (42) and the cylinder (43) to slide downward through the hydraulic cylinder (3). The cylinder (43) drives the connecting plate (51) and the elastic band (55) to slide downward. At this time, spray concrete to the connecting plate (51) through the auger pipe (2). In this way, limit the lower end of the connecting plate (51) to spray concrete through a plurality of elastic bands (55); By swinging the cylinder (43) to one side or the other, the cylinder (43) drives the connecting plate (51) and the connecting bar (53) to swing to one side or the other. Its hydraulic cylinder (3) is at the axis of the steel bar ring.

At this time, the liquid inside the piston plate (62) of the left positioning device (6) will be transmitted to the guiding device (7) at the left arc-shaped pipe (45), so that pure water fills the arc-shaped pipe (45), and the left arc-shaped pipe (45) is expanded to drive the connecting plate (51) to swing to the right, thus realizing the automatic sensing of the spring ring limit and automatically adjusting the position of the connecting plate (51). The limiting plug (78) is impacted and opened by the pure water, so that the pure water enters the circulation cavity (79) and the first hose (11). The pure water is transmitted to the connecting bar (53) through the first hose (11), and the pure water is sprayed through the connecting bar (53) to wash the concrete inside the mold, so that a large amount of sand and gravel can fall between the outer surface of the steel bar ring and the inner wall of the mold.
