Abstract
Description
Technical Field
[0001] This application relates to the technical field of pole production, and in particular, to a steam curing device, a steam curing method, and their application in the production of cement poles. Background Art
[0002] As the name implies, a pole is a pole for supporting electric wires and is one of the important early infrastructure facilities. All early poles started from wooden poles, even including high-voltage poles with relatively low voltage levels. Later, due to the development of steel and reinforced concrete and technical requirements, these two materials replaced most of the wooden poles. In the process of pole production, in order to improve the quality of the finished product, curing treatment is usually required after production.
[0003] The curing system of cement poles is a key process system to improve the output of cement poles and ensure the quality of cement poles. Therefore, it is necessary to adapt to local conditions according to materials, processes, equipment, etc. On the premise of ensuring the demolding strength, try to reduce the residual deformation and shorten the curing cycle. The commonly used steam curing method for cement poles at present is the pool-type curing process, and the steam curing pool is a device to accelerate the solidification of cement poles. For traditional cement poles, the pole skeleton needs to be placed in a mold, cement is filled into the mold and both ends of the mold are sealed. After centrifuging the mold and the pole in a centrifuge, the mold together with the pole is placed in a steam curing pool, and the method of drying with steam is used to accelerate the solidification of the pole.
[0004] During the curing process of cement poles inside the steam curing pool, due to the long length of the poles, steam is not easily introduced into the middle position inside the poles. As a result, when the poles are cured and solidified, the concrete at both ends of the poles has already solidified, but the middle part of the poles is still in a wet and dry state, which leads to an extended curing and steam curing cycle of the poles, thereby reducing the steam curing efficiency of cement poles. Summary of the Invention
[0005] In order to improve the steam curing efficiency of steam-cured cement poles, this application provides a steam curing device, a steam curing method, and their application in the production of cement poles.
[0006] In the first aspect, this application provides a steam curing device for the production of cement poles, adopting the following technical solutions:
[0007] A steam curing device for the production of cement poles includes a steam curing pool for steam-curing poles, a placement rack arranged in the steam curing pool and used for installing poles, a pole mold installed on the placement rack, and a steam curing component for delivering steam into the pole mold. The steam curing component includes a steam pipe extending into the pole mold, and a plurality of steam holes are opened on the steam pipe located inside the pole mold. The end of the steam pipe located outside the pole mold is connected to a steam source.
[0008] By adopting the above technical solution, when steam curing the cast pole, the pole can not only receive the steam in the steam curing tank, but also the additionally provided steam pipe can extend into the pole mold, so that the inside of the pole mold can also be filled with steam, ensuring that the steam can fill both the inside and outside of the pole mold, thereby improving the efficiency of steam curing the pole, enabling the pole to achieve common steam curing from the inside to the outside, and preventing the steam in the steam curing tank from being unable to effectively enter the longer pole mold.
[0009] Preferably, a moving component for controlling the movement of the steam pipe is further provided inside the steam curing tank. The moving component includes a fixed seat arranged at the end of the placement rack, a moving rack movably arranged on the fixed seat, and a moving member for controlling the movement of the moving rack. The steam pipe is fixed on the moving rack, and the length direction of the steam pipe is the same as the length direction of the pole mold.
[0010] By adopting the above technical solution, when the steam pipe conveys steam into the pole mold, the steam can be conveyed into the pole mold through the steam pipe. When the moving member controls the moving rack to move, the steam pipe can be accurately extended into the pole mold, avoiding the need for manual movement. In addition, by controlling the movement of the steam pipe through the moving component, the steam can evenly fill the inside of the pole mold, preventing the high-temperature steam from spraying on the concrete at one position for a long time, and preventing the water content of the concrete at the same position from increasing after receiving a large amount of high-temperature steam, resulting in the concrete falling under the action of gravity.
[0011] Preferably, the moving member includes a moving motor installed at the end of the fixed seat, a moving screw rotatably arranged on the fixed seat, and a guide rod arranged on the fixed seat. The moving screw and the guide rod are arranged in parallel, and their length directions are the same as the length direction of the steam pipe. Both the moving screw and the guide rod pass through the moving rack, and the moving screw is in threaded cooperation with the moving rack, while the guide rod is in sliding cooperation with the moving rack.
[0012] By adopting the above technical solution, the moving motor can control the forward and reverse rotation of the moving screw, so that the moving rack can reciprocate on the fixed seat, and finally the steam pipe can freely enter and exit the pole mold, enabling the steam to be evenly sprayed into the concrete inside the pole mold.
[0013] Preferably, two sets of moving components are provided, and the two sets of moving components are symmetrically arranged at both ends of the placement rack. Two steam pipes extend into the inside of the pole mold from both ends of the pole mold at the same time.
[0014] By adopting the above technical solution, the two sets of moving components provided can divide the steam pipe into two sections, avoiding the setting of a single steam pipe, which may lead to a relatively long length of the steam pipe. During the process of entering and exiting the electric pole mold, the end of the steam pipe far from the end of the moving frame will be bent and inclined under gravity, easily causing the end of the steam pipe to hit the concrete or the steam to be sprayed onto the concrete. When the steam volume is large, it is easy to impact and remove the concrete. Therefore, the steam pipe set in two sections can avoid the bending and inclination of the end of the steam pipe.
[0015] Preferably, a plurality of electric pole molds are arranged on the placing rack, and a plurality of steam pipes are fixed on the moving frame at the same time. A steam main pipe is connected to the ends of the plurality of steam pipes far from the electric pole mold. One end of the steam main pipe is connected to a flexible steam delivery pipe, and the end of the steam delivery pipe is connected to a steam source.
[0016] By adopting the above technical solution, when the steam source delivers steam into each steam pipe, the steam can first be delivered into the flexible steam delivery pipe, and then into the steam main pipe. The steam main pipe distributes the steam evenly into each steam pipe and finally sprays it out through the steam holes.
[0017] Preferably, relief holes for the movement of the steam pipe are arranged at both ends of the placing rack, and support auxiliary rollers are rotatably arranged at the positions of the relief holes on the placing rack. The steam pipe can be placed on the support auxiliary rollers.
[0018] By adopting the above technical solution, the steam pipe arranged to move can slide freely at the relief holes, avoiding the steam pipe hitting the placing rack; the steam pipe can be placed on the support auxiliary rollers, and the support auxiliary rollers can provide support during the movement of the steam pipe, avoiding the inclination of the steam pipe when it moves out of the electric pole mold, and ensuring that the steam pipe can always enter and exit the electric pole mold along the axis of the electric pole mold.
[0019] Preferably, a rotating component for controlling the rotation of the electric pole mold is further arranged on the placing rack. The rotating component includes support members arranged on the placing rack corresponding to each electric pole mold. The support members include a pair of support rods and a plurality of support wheels rotatably arranged on the support rods. The two support rods are arranged in parallel, and the two ends of the support rods are fixed to the placing rack. The plurality of support wheels are evenly arranged on the support rods. The electric pole mold is installed on the two support rods, and the outer wall of the electric pole mold contacts the support wheels.
[0020] By adopting the above technical solution, the provided support rods and support wheels can support the entire electric pole mold. The rotatably arranged support wheels can contact the outer wall of the electric pole mold, enabling the electric pole mold to rotate freely on the two support rods, allowing the electric pole to be cured to rotate centrifugally while receiving steam, and enabling the steam to be evenly sprayed into the electric pole mold.
[0021] Preferably, the rotating assembly includes a rotating member disposed between two adjacent pole molds. The rotating member includes a rotating rod rotatably disposed on the placement rack. The length direction of the rotating rod is the same as the length direction of the pole mold. A plurality of rotating wheels are fixed on the rotating rod, and the rotating wheels are in contact with the outer walls of two adjacent pole molds.
[0022] By adopting the above technical solution, when controlling the rotation of the pole mold on the support rod, the rotation of the rotating wheel can control the rotation of the pole mold, avoiding directly controlling the rotation of the relatively heavy pole mold by the motor.
[0023] Preferably, the rotating assembly includes a driving member for driving the simultaneous rotation of a plurality of pole molds. The driving member includes a driving sprocket fixed on each rotating rod and a chain sleeved on a plurality of driving sprockets. A driving motor is fixed on the placement rack, and the output shaft of the driving motor is fixed to the end of one of the rotating rods.
[0024] By adopting the above technical solution, the provided driving motor, under the action of the driving sprocket and the chain, can drive the simultaneous rotation of a plurality of rotating rods, thereby simultaneously controlling the rotation of a plurality of pole molds, controlling the rotation of a plurality of pole molds in the same direction, and controlling the pole molds to reach a specified rotation speed, enabling the pole molds to be steam-cured under the action of centrifugal force, improving the steam-curing efficiency of the concrete poles.
[0025] In a second aspect, the present application provides a steam-curing method for steam-curing cement poles by a steam-curing device, adopting the following technical solution:
[0026] A steam-curing method for steam-curing cement poles by a steam-curing device, characterized by comprising the following steps:
[0027] Install the pole mold: sequentially and accurately install the pole molds to be steam-cured on the placement rack, and align the two ends of the pole mold with the steam pipes.
[0028] Debug the steam-curing equipment: after the installation of the pole mold is completed, control the movement of the steam pipe so that the steam pipe can extend into the pole mold, and control the pole mold to be able to rotate freely on the placement rack.
[0029] Close the steam-curing pool and start the relevant electrical equipment: after debugging, cover the steam-curing pool with a sealing cover to keep the steam-curing pool relatively sealed, start the moving motor and the driving motor, and let the steam source start to supply steam into the steam-curing pool.
[0030] In summary, the present application includes at least one of the following beneficial technical effects:
[0031] 1. The steam curing device provided in this application can, during the steam curing process in the steam curing pond, also insert a movable steam pipe into the interior of the electric pole mold, directly delivering steam into the interior of the electric pole mold to prevent the steam in the steam curing pond from failing to smoothly enter the interior of the electric pole mold.
[0032] 2. The movable steam pipe can evenly spray steam to each position inside the electric pole mold, preventing the high-temperature steam from always spraying on one position and avoiding the water content of the concrete increasing when the same position of the concrete receives a large amount of high-temperature steam, which may cause the concrete to fall under the action of gravity.
[0033] 3. The two-section steam pipe provided can prevent a single steam pipe from being too long. During the process of entering and exiting the interior of the electric pole mold, the end of the steam pipe far from the end of the moving frame will bend and tilt under the action of gravity, easily causing the end of the steam pipe to hit the concrete or making the steam spray onto the concrete in a fitting manner. When the steam volume is large, it is easy to wash away the concrete. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0040] The following further elaborates on this application in conjunction with the attached Figures 1-5 drawings.
[0041] The invention technology involved in this application is summarized and designed by projects such as the annual production of 60,000 cement poles and 1,000 cubic meters of cement pole accessories, the storage and sales project of the coking coal power supply department, and the first distribution network material agreement inventory replenishment public bidding and procurement project of the State Grid Henan Electric Power Company in 2024. In the production and delivery of the above projects, during the curing process of cement poles in the steam curing tank, it is not easy for steam to enter the middle position of the longer poles, resulting in the concrete at both ends of the poles being solidified during curing, but the middle end is still in a dry and wet state, and the solidification state is uneven, resulting in the extension of the curing cycle of the poles and affecting the curing efficiency of the cement poles. To this end, as an innovative small and medium-sized enterprise, we have proposed a steam curing device for the production of cement poles disclosed in this application through continuous technological updates, aiming to improve the uniformity of the solidification state, so that the steam in the steam curing tank can smoothly enter the inside of the pole mold, improve the curing efficiency of the steam curing cement poles, and enable the poles to achieve common steam curing from the inside to the outside.
[0042] Example 1
[0043] Example 1 of the present application discloses a steaming device for producing cement utility poles.
[0044] Reference Figure 1 A steaming curing device for producing cement electric poles comprises a steaming curing tank 1 having a rectangular structure and an opening at the upper end, a sealing cover is arranged at the opening of the steaming curing tank 1, when the concrete electric poles to be steamed are placed in the steaming curing tank 1, the sealing cover is arranged to ensure that the interior is in a relatively sealed state, a placing rack 2 is arranged inside the steaming curing tank 1, the length direction of the placing rack 2 is the same as the length direction of the steaming curing tank 1, and the placing rack 2 is in a U-shaped structure, and a plurality of electric pole molds 3 to be steamed can be placed on the placing rack 2, so that the electric poles to be steamed can be steamed at the same time. The utility pole mold 3 is a cylindrical hollow structure with two ends open. When producing and processing utility poles, concrete is poured into the utility pole mold 3, and the concrete is thrown onto the inner walls around the utility pole mold 3 by a centrifuge. The poured utility pole mold 3 is installed on the placement rack 2. A steam source for conveying steam is also provided outside the steam curing tank 1. During the steam curing process, the steam source can convey steam into the steam curing tank 1 to fill the steam curing tank 1, thereby steam curing the concrete to be solidified.
[0045] Reference Figure 2 and Figure 3, an autoclaving component 4 for autoclaving electric poles is provided inside the autoclaving pool 1. The autoclaving component 4 includes steam pipes 41 arranged in the autoclaving pool 1. The length direction of the steam pipes 41 is the same as that of the electric pole mold 3. There are multiple steam pipes 41, and the number is the same as the number of electric pole molds 3 that can be placed, ensuring that each steam pipe 41 corresponds to each electric pole mold 3. The steam pipes 41 can extend into the electric pole mold 3. Steam holes 42 are provided on the steam pipes 41. The steam pipes 41 can be connected to a steam source, and steam can be ejected from the steam holes 42, allowing the steam to be sprayed onto the concrete inside the electric pole mold 3 and enabling the internal concrete to solidify quickly, improving the efficiency of autoclaving electric poles.
[0046] A moving component 5 for controlling the movement of the steam pipes 41 is provided inside the autoclaving pool 1 and at the end of the placement rack 2. The moving component 5 includes a fixed seat 51 fixed at the end of the placement rack 2. The fixed seat 51 is U-shaped, and the length direction of the fixed seat 51 is the same as that of the placement rack 2. A moving frame 52 is slidably fitted on the fixed seat 51. The length direction of the moving frame 52 is arranged along the width direction of the placement rack 2, enabling the moving frame 52 to slide towards the placement rack 2. Multiple steam pipes 41 are all fixed on the moving frame 52. The multiple steam pipes 41 are parallel to each other, and one end of the steam pipe 41 is fixed to the moving frame 52. When controlling the sliding of the moving frame 52, the multiple steam pipes 41 can extend into the corresponding electric pole molds 3. The steam holes 42 are provided at the end position where the steam pipes 41 extend into the electric pole molds 3, and there are multiple steam holes 42, which are evenly distributed along the circumferential direction of the steam pipes 41. By means of the movably arranged moving frame 52, the steam pipes 41 can slide in and out of the electric pole molds 3, allowing the steam to evenly fill the inside of the electric pole molds 3, avoiding the spraying of high-temperature steam on the concrete at one position, and preventing the water content of the concrete at the same position from increasing after receiving a large amount of high-temperature steam, resulting in the dropping of the concrete under the action of gravity.
[0047] Refer to Figure 2 and Figure 3, the moving assembly 5 further includes a moving member 53 disposed on the fixed seat 51 and controlling the movement of the moving frame 52. The moving member 53 includes a moving screw 531 rotatably disposed on the fixed seat 51 and a pair of guide rods 532 fixed on the fixed seat 51. The moving screw 531 and the two guide rods 532 are arranged in parallel, and the two guide rods 532 are symmetrically disposed on both sides of the moving screw 531. The length directions of the moving screw 531 and the guide rods 532 are both arranged along the moving direction of the steam pipe 41. The moving screw 531 and the two guide rods 532 simultaneously pass through the moving frame 52, and the moving screw 531 is in threaded engagement with the moving frame 52, and the guide rods 532 are in sliding engagement with the moving frame 52. A moving motor 533 is fixed to the end of the fixed seat 51 away from the placing rack 2, and the output shaft of the moving motor 533 is fixed to the end of the moving screw 531. When curing the utility pole, the moving motor 533 is started to control the moving frame 52 to reciprocate on the fixed seat 51, so that the steam pipe 41 can enter and exit the corresponding utility pole mold 3, so that the steam can be evenly sprayed into the concrete inside the utility pole mold 3.
[0048] Two groups of moving assemblies 5 are provided inside the curing pond 1, and the two groups of moving assemblies 5 are symmetrically disposed at both ends of the placing rack 2. Two steam pipes 41 can extend into the utility pole mold 3 from both ends at the same time. The sum of the lengths of the two steam pipes 41 is greater than the length of the utility pole mold 3 to be cured. Avoiding setting a single steam pipe 41 will result in a longer length of the steam pipe 41. During the process of entering and exiting the utility pole mold 3, the end of the steam pipe 41 far from the end of the moving frame 52 will tilt under gravity, which is likely to cause the end of the steam pipe 41 to hit the concrete or the steam to be sprayed onto the concrete. When the steam volume is large, it is easy to wash away the concrete. Therefore, setting the steam pipes 41 at both ends can prevent the ends of the steam pipes 41 from tilting; when controlling the two steam pipes 41 to enter and exit the utility pole mold 3, one of the steam pipes 41 can be allowed to enter the utility pole mold 3, and the other can be removed from the utility pole mold 3 to avoid simultaneously transporting a large amount of steam into the utility pole mold 3.
[0049] Refer to Figure 2 and Figure 4, at the end of multiple steam pipes 41 far away from the telegraph pole mold 3, a steam main pipe 43 is fixedly connected. The steam main pipe 43 communicates with each steam pipe 41, and at the end of the steam main pipe 43, a flexible steam delivery pipe 44 is connected. The steam delivery pipe 44 is connected to a steam source. The steam source can continuously transport high-temperature steam into the moving steam main pipe 43 and evenly disperse it into multiple steam pipes 41. At both ends of the placement rack 2, there are provided relief holes 21 for the normal entry and exit of the steam pipes 41 into the interior of the telegraph pole mold 3, to prevent the moving steam pipes 41 from hitting the ends of the placement rack 2. On the placement rack 2 and at the position of each relief hole 21, a support auxiliary roller 22 is rotatably provided. The steam pipe 41 can be placed on the support auxiliary roller 22, so that during the movement of the steam pipe 41, the support auxiliary roller 22 can provide support to prevent the steam pipe 41 from tilting when the steam pipe 41 moves out of the interior of the telegraph pole mold 3, and ensure that the steam pipe 41 can always enter and exit the interior of the telegraph pole mold 3 along the axis of the telegraph pole mold 3.
[0050] Refer to Figure 2 and Figure 4 , on the placement rack 2, there is also provided a rotation assembly 6 for controlling the rotation of the telegraph pole mold 3. The rotation assembly 6 includes support members 61 installed on the placement rack 2 and corresponding to each telegraph pole mold 3. The support members 61 include a pair of support rods 611. The two support rods 611 are arranged in parallel and along the length direction of the placement rack 2. The two ends of the support rods 611 are fixed to the placement rack 2. On each support rod 611, a plurality of support wheels 612 are rotatably provided. The plurality of support wheels 612 are evenly arranged on the support rod 611. The telegraph pole mold 3 to be steam-cured can be placed on the two support rods 611, and the outer walls of the telegraph pole mold 3 are respectively in contact with the support wheels 612 on the two support rods 611, so that the telegraph pole mold 3 can rotate on the placement rack 2, enabling the telegraph pole to be centrifugally rotated while receiving steam, and allowing the steam to be evenly sprayed into the interior of the telegraph pole mold 3.
[0051] Refer to Figure 2 and Figure 4, the rotating assembly 6 further includes a rotating member 62 disposed between adjacent two pole molds 3. The rotating member 62 includes a rotating rod 621 rotatably disposed on the placement rack 2. The rotating rod 621 is arranged along the length direction of the pole mold 3. A plurality of rotating wheels 622 are fixed on the rotating rod 621. The plurality of rotating wheels 622 are evenly arranged on the rotating rod 621. The rotating wheels 622 are respectively in contact with the outer walls of the two adjacent pole molds 3 on both sides. When controlling the rotation of the rotating rod 621, the rotating wheels 622 drive the two adjacent pole molds 3 to rotate in the same direction, providing a rotation speed for the pole mold 3. The rotating assembly 6 further includes a driving member 63 for driving the rotation of a plurality of rotating rods 621. The driving member 63 includes a driving sprocket 631 fixed on each rotating rod 621. The driving sprocket 631 is located inside the placement rack 2. A chain 632 is sleeved on the plurality of driving sprockets 631. A driving motor 633 is fixed at the end of the placement rack 2. The output shaft of the driving motor 633 is fixed to the end of one of the rotating rods 621. When controlling the rotation of a plurality of pole molds 3, the driving motor 633 is started. Under the action of the driving sprockets 631 and the chain 632, a plurality of pole molds 3 are controlled to rotate in the same direction, and the rotation speed of the pole mold 3 can be controlled to reach a specified value, so that the pole mold 3 is steam-cured under the action of centrifugal force, improving the steam-curing efficiency of the concrete pole.
[0052] The implementation principle of the steam-curing device for producing cement poles in the embodiment of the present application is as follows: The pole mold 3 filled with concrete is installed on the placement rack 2, so that during the steam-curing process of the pole, the pole mold 3 can rotate, avoiding the collapse of the non-primarily formed concrete in the early stage. When the pole mold 3 rotates, the steam pipe 41 can freely enter and exit the inside of the pole mold 3 under the action of the moving assembly 5, so that the steam can be evenly sprayed into the inside of the pole mold 3, thereby steam-curing the concrete inside the pole mold 3.
[0053] Embodiment 2
