Description
Technical Field
[0001] The invention belongs to the technical field of electric pole preparation, and in particular relates to energy-saving processing equipment for prefabricated cement electric poles. Background Art
[0002] During the preparation of prefabricated cement utility poles, cement, sand, gravel, water and additives are first mixed into concrete according to the proportions. Then the mold is cleaned, the release agent is applied, and the concrete is poured after the steel skeleton is placed. The concrete is made dense through centrifugal molding, and then steam-cured. The concrete is hardened through heating, constant temperature and cooling stages, and finally demolded and naturally cured until the strength meets the standard.
[0003] During the steam curing process of precast cement poles, traditional equipment mostly uses a single curing chamber structure. When a cold mold (with an initial temperature close to the ambient temperature) directly enters a high-temperature steam environment, there is a sharp temperature difference between the surface and the high-temperature steam, causing a large amount of steam to instantly liquefy, forming a continuous water film on the mold surface. This water film seriously hinders the heat transfer between the steam and the mold, making it difficult for the steam heat to act efficiently on the mold and the concrete inside. Not only does it increase steam consumption to compensate for heat loss, it also prolongs the time it takes to heat to the target temperature, reducing curing efficiency. At the same time, the continued retention of the water film on the mold surface will repeatedly undergo liquefaction and evaporation with temperature changes, which can easily lead to uneven heating of the mold and indirectly cause defects in the concrete due to thermal stress.

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.
[0037] Example 1:
[0038] like Figures 1 to 9 As shown, an energy-saving processing equipment for prefabricated cement utility poles includes a curing room 1.
[0039] A pair of cover plates 13 are slidably installed on the top of the curing chamber 1, and a partition plate 14 is slidably set at the bottom of each cover plate 13. A baffle 15 is installed inside the curing chamber 1, and the baffle 15 and the partition plate 14 cooperate with each other. The baffle 15 and the partition plate 14 are used to divide the interior of the curing chamber 1 into a curing chamber 17 and a preheating chamber 171. A clamping assembly for clamping the mold is rotatably installed inside the curing chamber 1. The curing chamber 17 is used to heat and cure the mold, and the mold inside the curing chamber 17 is heated, and part of its heat is transferred to the mold initial end of the preheating chamber through heat transfer from the mold for preheating the mold; in this structural design, the curing chamber 17 cures the mold through steam heating, and at the same time uses the heat transfer of the mold itself to transfer part of the heat to the mold initial end in the preheating chamber 171, realizing the secondary utilization of heat and achieving energy-saving effects, and the cooperation of the baffle 15 and the partition plate 14 ensures the relative independence of the two cavities, ensuring that the curing and preheating processes are carried out in an orderly manner.
[0040] A screw shaft 2 engaged with the baffle 15 is rotatably installed inside the curing chamber 1, and the screw shaft 2 is used to drive the baffle 15 to move, thereby changing the preheating position of the mold in the preheating chamber 171, ensuring that all parts of the mold can be evenly preheated, improving the preheating effect, and ensuring the quality of subsequent curing.
[0041] A turntable 22 is installed on the side wall of the curing chamber 1 and rotates synchronously with the screw shaft 2. The turntable 22 is used to drive the swing arm 23 installed on the side wall of the curing chamber 1 to swing, and the swing arm 23 drives the swing rod 24 installed at the rotation center of the clamping assembly to swing back and forth, and finally the clamping assembly drives the mold to swing back and forth. The inertia can be used to effectively clean the moisture on the surface of the mold, reducing the impact of moisture on the heating efficiency. At the same time, this mechanical transmission method is stable and reliable, and can ensure the consistency of the cleaning effect.
[0042] like Figures 1 to 9 As shown, in a specific embodiment, a base plate 11 is installed at the bottom of the curing chamber 1. Mounting holes 112 are provided at the four corners of the base plate 11. The mounting holes 112 are used to locate the curing chamber 1. A reinforcing rib 111 is provided at the connection between the curing chamber 1 and the base plate 11. The reinforcing rib 111 is triangular in shape. An exhaust hole 12 is provided on the side wall of the curing chamber 1. The exhaust hole 12 is connected to the preheating chamber 171. The base plate 11 can firmly position the curing chamber 1 at the designated position through the mounting holes 112. The triangular reinforcing rib 111 enhances the strength and stability of the connection between the curing chamber 1 and the base plate 11, preventing the equipment from shaking during operation. The exhaust hole 12 is connected to the preheating chamber 171, which can promptly discharge excess gas in the preheating chamber 171, maintain the stable air pressure in the chamber, and ensure the normal progress of the preheating process.
[0043] like Figures 1 to 9 As shown, the upper surface of the cover plate 13 is inclined to guide the mold as it slides into the curing chamber 1. A steam delivery pipe 131 is installed on the top of the cover plate 13 and communicates with the curing chamber 17. The inclined design of the upper surface of the cover plate 13 guides the mold to slide smoothly into the curing chamber 1, saving manpower and handling costs. The steam delivery pipe 131 is directly connected to the curing chamber 17, accurately delivering steam to the curing chamber 17, providing a sufficient heat source for heating and curing the mold, ensuring the curing effect.
[0044] like Figures 1 to 9As shown, further, a pair of fixing seats 144 are installed at the bottom of the cover 13, and a guide rod 142 is installed between the fixing seats 144. The guide rod 142 is slidably connected to the partition 14, and a magnet 143 is installed on the side wall of the fixing seat 144. The magnet 143 is used to adsorb the partition 14 and limit the initial position of the partition 14. A guide block 141 is installed on the side wall of the partition 14, and a guide groove 151 is opened on the baffle 15. The guide groove 151 and the guide block 141 are adapted to each other. An insertion rod 152 is provided through the baffle 15, and both ends of the insertion rod 152 are connected to the side wall of the curing room 1. The guide rod 142 provides guidance for the sliding of the partition 14, ensuring the stability of the movement of the partition 14; the magnet 143 adsorbs the partition 14, which can effectively limit the initial position of the partition 14 and prevent it from moving at will; the guide block 141 is adapted to the guide groove 151, and plays a guiding role when the partition 14 and the baffle 15 are matched, so that the two can be accurately docked; the insertion rod 152 fixes and supports the baffle 15, ensuring the stability of the baffle 15 during movement.
[0045] like Figures 1 to 9 As shown, further, a positioning block 16 is provided on the side wall of the baffle 15, and a positioning hole 161 is provided on the positioning block 16. A mounting plate 163 is mounted on the side wall of the partition 14, and a positioning rod 162 is mounted on the mounting plate 163. The positioning rod 162 and the positioning hole 161 are adapted to each other, and the entrance of the positioning hole 161 is chamfered to guide the positioning rod 162 to be inserted into the positioning hole 161. The adaptation of the positioning rod 162 and the positioning hole 161 can more firmly connect the partition 14 and the baffle 15 together, ensuring the reliability of the cavity segmentation; the chamfering treatment of the entrance of the positioning hole 161 facilitates the smooth insertion of the positioning rod 162 into the positioning hole 161, thereby improving the efficiency of the cooperation between the two.
[0046] like Figures 1 to 9 As shown, further, the clamping assembly includes a bracket 18 rotatably set on the side wall of the curing chamber 1, a positioning plate 182 is installed at the end of the bracket 18, three pairs of slide grooves 183 are installed on the positioning plate 182, and the intersection of the three pairs of slide grooves 183 is the same as the center of the positioning plate 182, and a slider 184 is slidingly set through the slide groove 183, a splint 185 is installed at one end of the slider 184, an electric push rod 187 is installed on the bracket 18, and a rocker arm 186 is rotatably set at the output end of the electric push rod 187, and the end of the rocker arm 186 is rotatably connected to the other end of the slider 184, and the rocker arm 186 is in an inclined state. When the electric push rod 187 is in operation, it drives the rocker arm 186 to rotate, and the rocker arm 186 pushes the slider 184 to slide in the slide groove 183, so that the clamping plates 185 move closer to or away from each other, thereby clamping or loosening the mold; the three pairs of slide grooves 183 are arranged with the center of the positioning plate 182 as the intersection, which can ensure that the clamping plates 185 clamp the mold from different directions, improve the stability of the clamping, and ensure that the mold will not shift during the swinging and maintenance process.
[0047] Example 2:
[0048] The difference between the above embodiment and this embodiment is that: Figures 1 to 9 As shown, a drive motor 21 is mounted on the base plate 11. A synchronous shaft 211 is mounted on the output end of the drive motor 21. The synchronous shaft 211 movably extends through the curing chamber 1. The screw shaft 2 is mounted on the side wall of the synchronous shaft 211. The synchronous shaft 211 is interconnected with the turntable 22. A protective cover 25 is mounted on the side wall of the curing chamber 1 to protect the turntable 22 and the rocker arm 24. The drive motor 21 simultaneously drives the screw shaft 2 and the turntable 22 to rotate via the synchronous shaft 211, achieving synchronous operation and ensuring the coordinated operation of the various components of the equipment. The protective cover 25 effectively prevents external dust, debris, etc. from eroding and interfering with the turntable 22 and the rocker arm 24, thereby extending the service life of these components.
[0049] like Figures 1 to 9 As shown, in a specific embodiment, a rotating shaft 232 is installed at the rotation center of the swing arm 23, and the rotating shaft 232 is installed on the side wall of the curing chamber 1, a strip groove 231 is provided on the swing arm 23, and the strip groove 231 is slidingly connected to the protrusion 221 installed at the eccentric position of the turntable 22, and a straight groove 241 is provided on the swing rod 24, and the straight groove 241 is slidingly connected to the slide rod 242 installed on the swing arm 23, and a positioning shaft 181 is installed at the rotation center of the swing rod 24, and the positioning shaft 181 is interconnected with the clamping assembly. When the turntable 22 rotates, the protrusion 221 slides in the strip groove 231, driving the swing arm 23 to swing around the rotating shaft 232, and the slide bar 242 on the swing arm 23 slides in the straight groove 241, thereby driving the rocker arm 24 to swing around the positioning axis 181. This transmission structure converts the rotational motion of the turntable 22 into the reciprocating swing of the rocker arm 24, thereby driving the clamping assembly to move. The transmission process is smooth and efficient, and the swing amplitude and frequency of the rocker arm 24 can be accurately controlled.
[0050] like Figures 1 to 9 As shown, guide rails 3 are installed on the side walls of the curing chamber 1, and several pairs of vertical rods 31 for support are vertically installed at the bottom of the guide rails 3. The guide rails 3 are composed of an inclined guide rail 311 and a vertical guide rail 312. The vertical guide rail 312 is connected to the curing chamber 1, and the inclined guide rail 311 and the vertical guide rail 312 are connected to each other. Polished rods 313 are installed on the side walls of the cover plate 13, and the polished rods 313 are slidably set on the guide rails 3. The vertical rods 31 provide stable support for the guide rails 3; the combination of the inclined guide rails 311 and the vertical guide rails 312, combined with the polished rods 313 on the side walls of the cover plate 13, provide precise guidance for the movement of the cover plate 13, so that the cover plate 13 can be smoothly closed on the top of the curing chamber 1 or opened, ensuring the smooth and accurate movement of the cover plate 13.
[0051] like Figures 1 to 9As shown, a hydraulic push rod 132 is installed inside the curing chamber 1. A slide 32 is installed at the output end of the hydraulic push rod 132. A pair of limit rods 321 are slidably mounted on the slide 32. Limit seats 322 are mounted at both ends of the pair of limit rods 321. The limit seats 322 are mounted on the bottom of the cover plate 13. A limit spring 323 is sleeved on the limit rod 321. One end of the limit spring 323 is clamped to the slide 32 and the other end is clamped to the limit seat 322. The hydraulic push rod 132 provides power for the movement of the cover plate 13, driving the cover plate 13 to move along the guide rail 3. The limit rod 321 and the limit spring 323 act as a buffer and limiter during the movement of the cover plate 13, preventing the cover plate 13 from being damaged by collision due to excessive speed or excessive force when moving, thereby ensuring the smooth operation of the cover plate 13.
[0052] The implementation principle of the energy-saving processing equipment for prefabricated cement utility poles of the present invention is as follows:
[0053] During operation, the energy-saving processing equipment for prefabricated cement utility poles first secures the entire curing chamber 1 in a designated position through the mounting holes 112 of the base plate 11. The reinforcing ribs 111 enhance the stability of the connection between the curing chamber 1 and the base plate 11. After the mold to be cured slides into the curing chamber 1 through the inclined surface of the cover plate 13, the operator activates the clamping assembly, causing the electric push rod 187 to operate. Its output end drives the rocker arm 186 to rotate, which pushes the slider 184 to slide within the slot 183 of the positioning plate 182, bringing the clamping plates 185 closer together and firmly clamping the mold, ensuring its stability during the swinging and curing process.
[0054] Next, the hydraulic push rod 132 inside the curing chamber 1 first drives the slide 32 downward, and the slide 32 pulls the entire cover 13 downward, thereby driving the cover 13 to move along the guide rail 3. The polished rod 313 on the side wall of the cover 13 first slides along the inclined guide rail 311, then enters the vertical guide rail 312, and finally the cover 13 is accurately closed on the top of the curing chamber 1.
[0055] During the closing process, the bottom partition 14 of the cover plate 13 also moves. At this time, the guide block 141 on the side wall of the partition 14 gradually fits into the guide groove 151 of the baffle 15. At the same time, the positioning rod 162 on the partition 14, driven by the mounting plate 163, aligns with the positioning hole 161 of the positioning block 16 on the baffle 15 (the chamfered design of the entrance of the positioning hole 161 assists the positioning rod 162 to insert smoothly). The magnet 143 attracts the partition 14 to maintain the stability of the initial position. Through this cooperation, the baffle 15 and the partition 14 jointly divide the interior of the curing chamber 1 into the curing chamber 17 and the preheating chamber 171.
[0056] The steam delivery pipe 131 on the top of the cover plate 13 delivers steam to the curing chamber 17, providing a heat source for the heating and curing of the mold. The temperature of the mold in the curing chamber 17 gradually increases under steam heating. Due to the heat transfer characteristics of the mold itself, part of the heat will be transferred to the initial end of the mold in the preheating chamber 171 to preheat it, realizing effective use of heat and achieving the purpose of energy saving. This preheating effect can significantly reduce the amount of liquefaction when steam directly contacts the colder mold. When the unpreheated cold mold comes into contact with high-temperature steam, the huge temperature difference will cause a large amount of steam to instantly liquefy and form a thick water film on the surface of the mold. The temperature difference between the surface temperature of the preheated mold and the steam is reduced, the steam liquefaction rate slows down, and the liquefaction amount is reduced, thereby reducing the water film's resistance to heat transfer, allowing the steam heat to be more efficiently used to increase the temperature of the mold and the concrete inside.
[0057] After the drive motor 21 is started, the synchronous shaft 211 at its output end begins to rotate, driving the screw shaft 2 and the turntable 22 to rotate synchronously. The screw shaft 2 engages with the baffle 15, and its rotation causes the baffle 15 to move, thereby switching the preheating position of the mold and ensuring uniform preheating effect.
[0058] At the same time, the screw shaft 2 rotates the turntable 22, which is equipped with a protrusion 221 at an eccentric position. As the turntable 22 rotates, the protrusion 221 slides within the strip groove 231 of the swing arm 23, driving the swing arm 23 to swing about the rotation axis 232. The slide bar 242 on the swing arm 23 slides within the straight groove 241 of the swing rod 24, driving the swing rod 24 to swing back and forth about the positioning axis 181. The clamping assembly connected to the positioning axis 181 also drives the mold to swing back and forth, using inertia to remove moisture from the mold surface, reducing the impact of moisture on heating efficiency.
[0059] During the rotation of the turntable 22, the protrusion 221 rotates continuously between the upper and lower halves of the turntable 22. The swing frequencies of the protrusion 221 in the upper and lower halves of the turntable 22 are inconsistent, and as the turntable 22 continues to rotate, the two frequencies continuously switch. This design has significant advantages. On the one hand, the alternating swing frequencies can subject the moisture on the mold surface to different inertial forces, avoiding the difficulty of removing moisture from some areas due to "adapting" to inertia caused by a single frequency. Especially when there are subtle grooves or corners on the mold surface, high-frequency swinging can quickly remove attached water droplets, while low-frequency swinging can force accumulated water to flow to the edges. The alternating combination of the two frequencies can more thoroughly remove moisture. On the other hand, this alternating switching can reduce fatigue damage to the mold and clamping components. If the swing frequency is maintained at a single frequency for a long time, the components are prone to local wear or deformation under a fixed force rhythm. Alternating frequencies can continuously change the force points and force intensity, dispersing stress and extending the service life of the equipment.
[0060] When the hydraulic push rod 132 inside the curing chamber 1 pushes the slide 32, the limit rod 321 and limit spring 323 cushion and limit the movement of the cover plate 13, ensuring smooth operation of the cover plate 13. The exhaust hole 12 in the side wall of the curing chamber 1 communicates with the preheating chamber 171, allowing for the timely discharge of excess gas within the preheating chamber 171 and maintaining a stable environment within the chamber. The protective cover 25 protects components such as the turntable 22 and the rocker arm 24, extending the service life of the equipment.
