Description

Technical Field

[0001] This utility model relates to the field of concrete utility pole technology, specifically to an energy-saving concrete utility pole casting device. Background Technology

[0002] Concrete utility poles are rod-shaped structures manufactured using centrifugal molding technology. They consist of concrete encasing a steel reinforcement frame. Concrete is filled into a casting device using a material feeding device. After the casting device is closed, it is rotated by a centrifugal device, allowing the concrete inside to fully adhere to the inner wall of the casting device. Finally, the utility pole is removed. However, traditional casting devices do not easily allow air to escape from the concrete, which can lead to air pockets remaining on the surface of the utility pole during subsequent production.

[0003] To overcome the aforementioned deficiencies, existing technology (Chinese Patent No. CN220922809U, Publication Date: 2024-05-10) provides a concrete pole casting device, comprising a first half-mold and a second half-mold. The second half-mold is positioned above the first half-mold. Both the first and second half-molds have forming cavities inside. A reinforcing cage clamping mechanism is provided at one end of the second and first half-molds. The reinforcing cage clamping mechanism includes a clamping cover plate and clamping sleeves. The clamping cover plate is located at one end of the first and second half-molds. Through the designed reinforcing cage clamping mechanism, the clamping cover plate can be controlled to separate from the adjusting slide block, exposing the clamping sleeves. The clamping sleeves circumferentially distributed on the inner end face of the clamping cover plate can be used to clamp reinforcing bars to achieve the purpose of on-site reinforcing cage fabrication, while ensuring accurate positioning and stable placement of the reinforcing cage.

[0004] The aforementioned mechanism restricts the position of the reinforcing bars by using a reinforcing cage clamping mechanism. However, in actual use, the pouring device is equipped with a separate limiting ring that is connected to the reinforcing bars to limit their position. Therefore, the reinforcing bars will not shift in position when placed. However, during the pouring process, when the concrete is piled up, a lot of air may not be able to escape. Using centrifugal equipment alone cannot completely adhere the concrete to the inner wall of the pouring device. This may result in air holes remaining on the surface of the utility pole when it is demolded, affecting the overall quality. Utility Model Content

[0005] The purpose of this utility model is to provide an energy-saving concrete pole casting device to solve the problem mentioned in the background art that traditional casting devices are not convenient to expel air from inside the concrete during use, which easily leads to air pores remaining on the surface of the pole during subsequent production.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving concrete pole casting device, comprising a casting mold, positioning plates at both ends of the casting mold, steel cables installed inside the casting mold, limit frames engaging with the left and right sides of the bottom of the casting mold, and support legs installed at both ends of the bottom of the limit frames; a fixing plate installed at one end between the support legs, and a striking mechanism for reducing air bubbles in the cement mortar provided at the lower end of the fixing plate, the striking mechanism comprising a push rod engaging with the lower end of the fixing plate, the top end of the push rod passing through the fixing plate and having a striking block installed thereon, and a fixing groove matching the striking block being provided at the middle position of the bottom of the limit frame; a fixing rod installed at the front end of each support leg, and a limiting mechanism for preventing the device from shifting position at the bottom end of the fixing rod.

[0007] Furthermore, a connecting spring is wound around the upper end of the outer side of the push rod, and the fixing plate and the push rod form an elastic structure through the connecting spring.

[0008] Furthermore, a drive motor is installed on the side of the support leg, and a first cam is installed at the output end of the drive motor, the first cam being located below the push rod.

[0009] Furthermore, the striking block is positioned below the casting mold, and the upper surface of the striking block is arc-shaped, with the upper surface of the striking block having the same arc as the lower surface of the casting mold.

[0010] Furthermore, the limiting mechanism includes a suction cup, which is fixedly connected to the bottom end of the fixed rod. A piston is slidably connected inside the fixed rod, and a movable rod is installed at the top of the piston. The movable rod passes through and extends above the fixed rod, and a pressing plate is installed at the top of the movable rod.

[0011] Furthermore, a return spring is wound around the outside of the movable rod, and the return spring is positioned above the fixed rod. A sealing gasket is provided at the top of the fixed rod, and the bottom end of the sealing gasket is in contact with the top end of the fixed rod. The bottom end of the return spring is connected to the top end of the sealing gasket, and the sealing gasket is sleeved on the outside of the movable rod.

[0012] Furthermore, the output end of the drive motor is equipped with a second cam via a sprocket transmission mechanism, and the second cam is rotatably connected to one side between the support legs. The second cam is positioned above the pressing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The first cam is driven to rotate by the output end of the drive motor. When the first cam rotates, it will simultaneously squeeze the push rod, thus realizing the reciprocating movement of the push rod. During the movement, the push rod will push the striking block upward. When the striking block moves upward, it will pass through the fixed groove and strike the bottom of the casting mold, thereby reducing the air in the concrete inside the casting mold. This effectively reduces the number of air pores remaining on the surface of the casting mold when it is centrifuged and rotated in a centrifuge.

[0015] Furthermore, when the push rod is repeatedly pushed upwards, when the protruding part of the first cam rotates to the lower end, the push rod will automatically reset by the elastic force of the connecting spring. After the push rod resets, the bottom end of the push rod fits against the outer side of the first cam, so that the first cam can reciprocate to push the push rod.

[0016] Furthermore, by providing a fixed groove, the top of the striking block can stably pass through the groove and strike the bottom of the casting mold. This increases the contact area between the cement mortar filling the casting mold and the inner wall of the casting mold, thereby preventing excessive air holes from remaining on the surface of the utility pole during the production process.

[0017] 2. By pressing the pressing plate, the movable rod at the bottom of the pressing plate is pressed down, which in turn causes the movable rod to move downward and drive the piston to slide inside the fixed rod. This pushes the air inside the fixed rod downward and discharges it from the bottom of the suction cup. The elastic force of the return spring drives the movable rod to return to its original position, which in turn causes the movable rod to drive the piston to move upward inside the fixed rod, in the opposite direction to extract the air inside the suction cup. This keeps the suction cup in a vacuum state and allows it to adhere to the ground, thus achieving the limiting of the overall position of the device.

[0018] Furthermore, during the rotation of the output end, the second cam can be synchronously driven to rotate through the sprocket transmission mechanism. When the second cam rotates, it presses the pressing plate. Therefore, when driving the striking mechanism to strike, the limiting mechanism can be squeezed and limited simultaneously, avoiding the overall positional displacement of the device during striking. The limiting mechanism can adjust the number of presses and the pressing depth as needed. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4The technical solution shown addresses the problem that during the pouring process, when concrete is piled up, a large amount of air cannot be expelled, and centrifugal rotation alone cannot completely adhere the concrete to the inner wall of the pouring device, resulting in air pores remaining on the surface of the utility pole during demolding, affecting the overall quality. This energy-saving concrete utility pole pouring device discloses a striking mechanism, including a pouring mold 1. Positioning plates 2 are provided at both the front and rear ends of the pouring mold 1. Steel cables 3 are installed inside the pouring mold 1. Limiting frames 4 are engaged and connected to the left and right sides of the bottom of the pouring mold 1, and support legs 5 are installed at both the front and rear ends of the bottom of the limiting frames 4. A fixing plate 6 is installed at one end between the support legs 5, and the lower end of the fixing plate 6 is provided with a feature to reduce cement residue buildup. The mortar internal air bubble knocking mechanism includes a push rod 12, which is engaged with the lower end of the fixed plate 6. The top end of the push rod 12 passes through the fixed plate 6 and is fitted with a knocking block 8. A fixing groove 7 matching the knocking block 8 is provided at the middle position of the bottom end of the limiting frame 4. A connecting spring 9 is wound around the upper end of the outer side of the push rod 12, and the fixed plate 6 and the push rod 12 form an elastic structure through the connecting spring 9. A drive motor 11 is installed on the side of the support leg 5, and a first cam 10 is installed at the output end of the drive motor 11. The first cam 10 is located below the push rod 12. The knocking block 8 is located below the casting mold 1, and the upper end surface of the knocking block 8 is arc-shaped, with the upper end surface of the knocking block 8 having the same arc as the lower end of the outer side of the casting mold 1.

[0028] In this example, both the reinforcing bar and the steel cable 3 are placed inside the casting mold 1. A limiting ring is then used to fix the position of the reinforcing bar and the steel cable 3. Next, a steel wire rope is wrapped around the outside of the reinforcing bar and the steel cable 3. Concrete is placed inside the lower half of the casting mold 1. A plasticizing device is used to plasticize the concrete filling the casting mold 1. Then, bolts are used to lock the positioning plates 2 on the sides of the two casting molds 1. The steel cable 3 is then tightened using a stress gun to ensure the load-bearing capacity of the utility pole. After the concrete is filled, the output of the drive motor 11 drives the first cam 10 to rotate. As the first cam 10 rotates, it simultaneously compresses the push rod 12, causing the push rod 12 to reciprocate. During this movement, the push rod 12 pushes the striking block 8 upwards. As the striking block 8 moves upwards, it passes through the fixing groove 7 and impacts the concrete. The bottom of the casting mold 1 is struck, thereby reducing the air in the concrete inside the casting mold 1. This effectively reduces the number of air pores remaining on the surface of the casting mold 1 when it is centrifuged. When the push rod 12 is repeatedly pushed upward, when the protruding part of the first cam 10 rotates to the lower end, the push rod 12 will automatically reset by the elastic force of the connecting spring 9. After the push rod 12 is reset, the bottom end of the push rod 12 fits against the outer side of the first cam 10, so that the first cam 10 can reciprocate to push the push rod 12. The fixed groove 7 allows the top of the striking block 8 to stably pass through the fixed groove 7 and strike the bottom of the casting mold 1. This increases the contact area between the cement mortar filling the casting mold 1 and the inner wall of the casting mold 1, thereby avoiding excessive air pores remaining on the surface of the utility pole during the production process.

[0029] Example 2: Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6The technical solution shown addresses the problem of positional deviation caused by impact during the use of the pouring device. This energy-saving concrete pole pouring device discloses a limiting mechanism. A fixed rod 14 is installed at the front end of each support leg 5, and a limiting mechanism to prevent device positional deviation is provided at the bottom end of the fixed rod 14. The limiting mechanism includes a suction cup 15, which is fixedly connected to the bottom end of the fixed rod 14. A piston 20 is slidably connected inside the fixed rod 14, and a movable rod 19 is installed at the top end of the piston 20. The movable rod 19 passes through and extends above the fixed rod 14, and a pressing plate 16 is installed at the top end of the movable rod 19. A return spring 17 is wound around the outside of the movable rod 19 and is positioned above the fixed rod 14. A sealing gasket 18 is provided at the top end of the fixed rod 14, and the bottom end of the sealing gasket 18 is in contact with the top end of the fixed rod 14. The bottom end of the return spring 17 is connected to the top end of the sealing gasket 18, and the sealing gasket 18 is sleeved on the outside of the movable rod 19.

[0030] In this example, pressing the pressing plate 16 presses down the movable rod 19 at its bottom, causing it to move downwards and slide the piston 20 inside the fixed rod 14. This pushes the air inside the fixed rod 14 downwards and expels it from the bottom of the suction cup 15. The spring force of the return spring 17 resets the movable rod 19, causing it to move the piston 20 upwards inside the fixed rod 14, thus drawing out the air inside the suction cup 15. This maintains a vacuum inside the suction cup 15, allowing it to adhere to the ground, thereby achieving the desired effect. The overall position is limited; when the piston 20 and the movable rod 19 move upward and exhaust gas, the sealing gasket 18 will be pushed upward due to the increased pressure caused by the compression of gas, thereby causing the compressed gas inside the fixed rod 14 to be discharged. When the movable rod 19 and the piston 20 inside the fixed rod 14 stop moving upward, the gas inside the fixed rod 14 is no longer compressed. Therefore, the remaining gas pressure inside the fixed rod 14 is balanced with the external gas pressure. The sealing gasket 18 automatically resets and seals the exhaust hole at the top of the fixed rod 14, reducing the entry of external gas into the interior of the fixed rod 14.

[0031] Example 3: Figure 1 , Figure 2 and Figure 3 The technical solution shown is designed to address the problem that the pouring equipment is prone to displacement due to vibration during the venting process: the energy-saving concrete pole pouring device discloses a second cam 13. The output end of the drive motor 11 is equipped with the second cam 13 through a sprocket transmission mechanism, and the second cam 13 is rotatably connected to one side between the support legs 5. The second cam 13 is located above the pressing plate 16.

[0032] In this example, during the rotation of the output end of 21, the second cam 13 can be driven to rotate synchronously through the sprocket transmission mechanism. When the second cam 13 rotates, it will press the pressing plate 16. Therefore, when 21 drives the striking mechanism to strike, it can simultaneously squeeze and limit the limiting mechanism, avoiding the overall positional deviation of the device during striking. The limiting mechanism can adjust the number of presses and the pressing depth as needed, thereby increasing the overall flexibility during use.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
