Description
Technical Field
[0001] This invention relates to the field of cement pole demolding technology, specifically a constraint-type cement pole demolding vibration device. Background Technology
[0002] As a core foundation component for the erection of power and communication lines, cement poles require a demolding process after production to separate the mold from the pole body. Vibration-assisted demolding is a key process in cement pole production. By applying controllable vibration to the mold, the adhesion between the pole body and the inner wall of the mold can be eliminated, reducing demolding resistance. This is the core means to achieve efficient and non-destructive demolding of cement poles and is widely used in large-scale pole production.
[0003] Existing concrete pole demolding vibration devices generally rely solely on a vibratory motor to provide vibration force. During demolding, the mold is prone to bouncing excessively, resulting in hard impacts with surrounding components, causing mold deformation and damage to the finished pole. Furthermore, the limiting adaptability is poor, and the single bottom vibration mode has limited vibration force transmission, making it difficult to quickly eliminate the adhesion between the mold and the pole, leading to low demolding efficiency. It fails to simultaneously meet the dual requirements of mold protection and improved demolding efficiency during the demolding process. Therefore, a new technical solution is proposed to address these issues. Summary of the Invention
[0004] The purpose of this invention is to provide a constrained concrete pole demolding vibration device, which solves the problems mentioned in the background art. Existing demolding vibration devices generally rely solely on a vibration motor to provide vibration force, and the mold is prone to bounce too high during demolding, resulting in hard impact with surrounding components. Furthermore, the single bottom vibration mode has limited vibration force transmission and low demolding efficiency.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a constraint-type cement pole demolding vibration device, comprising a base, two constraint frames on the surface of the base, a placement frame above the constraint frames, a vertical frame at the edge of the base, a lifting frame slidably connected to the surface of the vertical frame, a constraint assembly between the left and right inner sidewalls of the lifting frame, the constraint assembly comprising two rotating rods for constraint and shielding from above during vibration;
[0006] The top of the lifting frame is welded with a top frame, and the surface of the top frame is provided with an impact component. The impact component includes four limit frames and four impact blocks, which are used to intermittently impact the electric pole mold from above to assist in the demolding operation.
[0007] In this technical solution, by setting up constraint components, the height of the lifting frame can be precisely adjusted for pole molds of different sizes. The fixed ring and telescopic block on the surface of the rotating rod form a flexible limiting constraint on the mold, effectively limiting the bounce height of the mold during vibration and avoiding mold deformation and pole damage caused by hard impact. At the same time, the second servo motor drives the rotating rod to rotate, causing the telescopic block to intermittently collide with the mold. This forms a coordinated vibration with the bottom vibration of the vibration motor below, greatly improving the transmission effect of vibration force, quickly eliminating the adhesion between the mold and the pole, and significantly improving demolding efficiency.
[0008] Preferably, both of the rotating rods are rotatably connected between the left and right inner sidewalls of the lifting frame. Several fixed rings are fixedly connected at equal intervals on the surface of the rotating rods. A telescopic block is slidably connected to the inner side of the groove on the outer surface of the fixed ring. A corresponding spring is fixedly connected between the telescopic block and the inner wall of the groove of the fixed ring.
[0009] In practical applications, the telescopic block contacts molds of different specifications through the elasticity of the spring, and can intermittently collide with the mold surface when rotating, ensuring that the vibration force of the impact is uniform.
[0010] Preferably, one of the rotating rods has a No. 1 gear fixedly connected to both ends, and the other rotating rod has its two ends connected to the outer end of the drive shaft of the No. 2 servo motor and the corresponding No. 1 gear, respectively. The No. 2 servo motor is fixedly connected to the outer wall surface of the lifting frame.
[0011] In practical applications, the second servo motor drives one of the rotating rods to rotate, and through the meshing of the first gear, it drives the other rod to rotate synchronously. The two rods rotate in opposite directions at the same speed, which makes the impact on the mold more uniform, and the gear transmission is precise and stable.
[0012] Preferably, all four impact blocks penetrate the top frame and are slidably connected to it, and the four limiting frames are located on one side of the four impact blocks and fixed to the top frame. A corresponding spring is fixedly connected between the impact block and the surface of the corresponding limiting frame.
[0013] In practical applications, the limit bracket provides a compression support point for the spring, which allows the impact block to increase the impact force and improve the vibration effect when released.
[0014] Preferably, a third gear is rotatably connected to the outer surface of the lifting frame on the same side as the second servo motor. The third gear meshes with a first gear on one side. A lifting block is fixedly connected to the side of the third gear facing the top frame. The four impact blocks are simultaneously fixedly connected to the synchronizing rod, and the lifting block contacts the synchronizing rod.
[0015] In practical applications, gear one drives gear three to rotate, the lifting block rotates accordingly, and lifts the synchronizing rod, thereby realizing the synchronous power storage of the four impact blocks. The action is smooth and without jamming, improving the stability of impact demolding.
[0016] Preferably, two No. 2 gears are rotatably connected between the two No. 1 gears on the outer surface of the lifting frame. The two No. 2 gears mesh with each other, and the two No. 1 gears mesh with their corresponding No. 2 gears. The No. 2 gears and the No. 2 servo motor are located on the left and right outer walls of the lifting frame, respectively.
[0017] In practical applications, the two No. 2 gears enable the No. 1 gears on both sides to rotate in opposite directions at the same speed, making the rotation of the double rotating rods smoother, while also dispersing gear wear and extending the service life of the components.
[0018] Preferably, a lead screw is rotatably connected between the upper and lower inner walls of the vertical frame, and two slide rods are fixedly connected thereto. Both the lead screw and the slide rods pass through the lifting frame. The lead screw is threadedly connected to the lifting frame, and the slide rods are slidably connected to the lifting frame. A servo motor is fixedly connected to the top of the vertical frame, and the tail end of the drive shaft of the servo motor is connected to the top of the lead screw via a coupling.
[0019] In practical applications, the No. 1 servo motor drives the lead screw to rotate, enabling precise lifting of the lifting frame. It is adaptable to molds of different heights, with high adjustment accuracy and convenient operation, greatly improving the adaptability of the device.
[0020] Preferably, a vibration motor is installed on the bottom surface of the placement rack, a storage groove is provided between the left and right side walls of the placement rack, two pull-out brackets are slidably connected to the inner side of the storage groove, and the surface of the pull-out brackets is provided with several screw holes.
[0021] In practical applications, the vibration motor provides the basic vibration force, the pull-out frame can slide and adjust the spacing, and the screw holes can be used to adapt to molds of different lengths, effectively limiting the lateral movement of the mold away from the placement frame and improving the stability of the demolding operation.
[0022] Preferably, the two legs at the bottom of the placement frame are respectively inserted into the inner sides of the two constraint frames, and corresponding springs are fixedly connected between the legs of the placement frame and the inner wall of the constraint frame.
[0023] In practical applications, the springs in the support legs of the mounting frame form an elastic buffer, which can amplify the vibration force of the vibrating motor, reduce the transmission of vibration to the base, avoid equipment resonance, and improve the efficiency of vibration force transmission.
[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0025] 1. This invention, by setting up a height-adjustable constraint component, can precisely adjust the height of the lifting frame for pole molds of different sizes. The fixed ring and telescopic block on the surface of the rotating rod form a flexible limiting constraint on the mold, effectively limiting the bounce height of the mold during vibration and avoiding mold deformation and pole damage caused by hard impact. At the same time, the second servo motor drives the rotating rod to rotate, causing the telescopic block to intermittently collide with the mold. This, together with the bottom vibration of the vibration motor below, forms a coordinated vibration from top to bottom, greatly improving the transmission effect of vibration force, quickly eliminating the adhesion between the mold and the pole, and significantly improving demolding efficiency.
[0026] 2. This invention features a top frame at the top of the lifting frame. As the rotating rod rotates, the transmission of gears one and two ultimately drives gear three to rotate. During the rotation of gear three, the lifting block on its surface pushes up the synchronizing rod, thereby causing the impact block to move upward and compress the spring. When the lifting block disengages from the synchronizing rod, the impact block is released, intermittently impacting the mold. This structure, together with the constraint component and bottom vibration, forms a triple vibration demolding mechanism, further enhancing the effect of vibration on the adhesive surface. At the same time, the entire impact action is achieved through gear linkage, requiring no additional power source, significantly improving the integration of the device and demolding efficiency.

[0034] To make the technical means, creative features, objectives and effects of the present invention easier to understand, the following detailed description is provided in conjunction with specific embodiments.
[0035] A constrained concrete pole demolding vibration device, see [link / reference] Figures 1 to 5 The device includes a base 1, with two constraint frames 2 on the surface of the base 1. A placement rack 3 is located above the constraint frames 2. A vertical frame 5 is located at the edge of the base 1. A lifting frame 6 is slidably connected to the surface of the vertical frame 5. A constraint assembly is located between the left and right inner walls of the lifting frame 6. The constraint assembly includes two rotating rods 7, which are used to constrain and shield from above during vibration. Both rotating rods 7 are rotatably connected between the left and right inner walls of the lifting frame 6. Several fixing rings 8 are fixedly connected at equal intervals on the surface of the rotating rods 7. A telescopic block 801 is slidably connected to the inner side of the groove on the outer surface of the fixing ring 8. A corresponding spring is fixedly connected between the telescopic block 801 and the inner wall of the groove of the fixing ring 8.
[0036] In the above technical solution, the constraint frame 2 forms a bottom limit for the placement frame 3, while the vertical frame 5 provides lifting guidance for the lifting frame 6. The constraint component is a flexible limiting and auxiliary vibration structure. By adjusting the vertical height of the lifting frame 6, the rotating rod 7 reaches the upper position of the mold. The telescopic block 801 on the fixed ring 8 flexibly contacts the outer wall of the mold under the elastic action of the spring, forming a non-rigid limiting constraint. During vibration, it can effectively limit the height of the mold's bounce, avoiding hard impact with surrounding components that could cause mold deformation and damage to the finished pole. At the same time, when the rotating rod 7 rotates, the telescopic block 801 moves in a circular motion and intermittently touches the outer wall of the mold, forming a coordinated upper and lower vibration with the bottom vibration of the placement frame 3 below. This significantly improves the transmission coverage of the vibration force and quickly eliminates the adhesion between the mold and the pole body. This structure is adaptable to the limiting requirements of molds of different specifications and effectively solves the problem of low demolding efficiency of traditional single bottom vibration.
[0037] Specifically, such as Figure 1 and Figure 4 As shown, one of the rotating rods 7 has a first gear 10 fixedly connected to both ends, and the other rotating rod 7 has its two ends connected to the outer end of the drive shaft of the second servo motor 9 and the corresponding first gear 10, respectively. The second servo motor 9 is fixedly connected to the outer wall surface of the lifting frame 6. The second servo motor 9 provides a stable power source for the rotational movement of the constraint component. It directly drives one of the rotating rods 7 to rotate, and the first gear 10 at the other end of the rotating rod 7 rotates synchronously. Through gear meshing, it drives the other rotating rod 7 to rotate synchronously, realizing that the two rotating rods 7 rotate in opposite directions at the same speed, making the intermittent collisions on the upper part of the mold more uniform. At the same time, the gear transmission method provides precise power transmission and smooth operation without jamming or slippage, ensuring that the collision frequency of the telescopic block 801 on the mold is stable.
[0038] Furthermore, such as Figure 4 and Figure 5 As shown, a third gear 12 is rotatably connected to the outer surface of the lifting frame 6 on the same side as the second servo motor 9. The third gear 12 meshes with a first gear 10 on one side. A lifting block 121 is fixedly connected to the side of the third gear 12 facing the top frame 13. When the first gear 10 rotates with the rotating rod 7, it drives the third gear 12 to rotate synchronously through gear meshing. During the rotation of the third gear 12, the lifting block 121 on its surface also performs a circular motion, providing lifting power for the intermittent impact of the subsequent impact component. This structure allows the constraint component and the impact component to cooperate with each other, transmitting the rotational power of the rotating rod 7 to the impact component, eliminating the need for a separate power source for the impact component and greatly simplifying the device structure.
[0039] In one optional embodiment, a top frame 13 is welded to the top of the lifting frame 6. The surface of the top frame 13 is provided with an impact assembly, which includes four limit frames 14 and four impact blocks 15, for intermittently impacting the electric pole mold from above to cooperate with the demolding operation. The four impact blocks 15 all penetrate the top frame 13 and are slidably connected to the top frame 13. The four limit frames 14 are respectively located on one side of the four impact blocks 15 and fixed to the top frame 13. A corresponding spring is fixedly connected between the impact block 15 and the surface of the corresponding limit frame 14. The four impact blocks 15 are simultaneously fixedly connected to the synchronizing rod 16, and the lifting block 121 is in contact with the synchronizing rod 16.
[0040] In the above technical solution, gear 12 drives the lifting block 121 to rotate. When the lifting block 121 rotates to below the synchronizing rod 16, its continued rotation will push the synchronizing rod 16 upward. The synchronizing rod 16 drives the four impact blocks 15 to slide vertically upward along the top frame 13 and compress the spring, thus accumulating force. When the lifting block 121 rotates to the position where it is disengaged from the synchronizing rod 16, the synchronizing rod 16 loses its obstruction, and the elastic restoring force of the spring is quickly released, causing the impact blocks 15 to slide downward and impact the top of the mold. This structure, together with the vibration of the bottom vibration motor 4 and the intermittent collision of the constraint components, forms a triple vibration demolding combination, applying vibration force to the mold from multiple directions, greatly enhancing the effect of vibration force on the adhesion surface between the mold and the electric rod, accelerating their separation, and significantly improving demolding efficiency.
[0041] Furthermore, such as Figure 1As shown, two No. 1 gears 10 on the outer surface of the lifting frame 6 are rotatably connected to two No. 2 gears 11. The two No. 2 gears 11 mesh with each other, and the two No. 1 gears 10 mesh with their corresponding No. 2 gears 11. The No. 2 gears 11 and the No. 2 servo motor 9 are located on the left and right outer walls of the lifting frame 6, respectively. The two No. 2 gears 11 mesh with each other and mesh with the No. 1 gears 10 on both sides, forming a double-sided gear linkage structure. When the No. 1 gear 10 on one side rotates, it drives the No. 1 gear 10 on the other side to rotate synchronously through the transmission of the No. 2 gear 11, realizing synchronous transmission at both ends of the two rotating rods 7.
[0042] It is worth noting that, such as Figure 1 and Figure 2 As shown, a vibration motor 4 is installed on the bottom surface of the placement rack 3. A storage groove 301 is provided between the left and right side walls of the placement rack 3. Two pull-out brackets 302 are slidably connected to the inner side of the storage groove 301. Several screw holes are provided on the surface of the pull-out brackets 302. Two support legs at the bottom of the placement rack 3 are respectively inserted into the inner side of two constraint frames 2, and corresponding springs are fixedly connected between the support legs of the placement rack 3 and the inner wall of the constraint frame 2.
[0043] In the above technical solution, the vibration motor 4 provides the basic demolding vibration force for the device, generating high-frequency vibration during operation. The vibration force is transmitted to the pole mold through the placement frame 3, realizing vibration demolding. The springs between the legs of the placement frame 3 and the constraint frame 2 form an elastic buffer structure, which can amplify the vibration effect and prevent the vibration from being directly transmitted to the base 1, causing equipment resonance. The pull-out frame 302 can slide horizontally along the storage groove 301. With the help of the surface screw holes, it can block and limit the molds of different lengths at both ends, effectively preventing them from laterally detaching from the placement frame 3. This adapts to the load-bearing requirements of cement pole molds of different lengths, improving the adaptability of the device.
[0044] It is worth noting that, such as Figure 2 and Figure 3 As shown, a lead screw 501 is rotatably connected between the upper and lower inner walls of the vertical frame 5, and two slide rods 502 are fixedly connected. Both the lead screw 501 and the slide rods 502 pass through the lifting frame 6. The lead screw 501 is threadedly connected to the lifting frame 6, and the slide rods 502 are slidably connected to the lifting frame 6. A servo motor 503 is fixedly connected to the top of the vertical frame 5. The tail end of the drive shaft of the servo motor 503 is connected to the top of the lead screw 501 via a coupling. The operation of the servo motor 503 drives the lead screw 501 to rotate. Through the threaded engagement between the lead screw 501 and the lifting frame 6, the rotational motion is converted into the vertical linear motion of the lifting frame 6. The lead screw 501 transmission method has high adjustment precision and can accurately adjust the position of the lifting frame 6 according to the mold height, making the contact position between the constraint component and the mold more precise, and improving the limiting and auxiliary vibration effects.
[0045] In addition, all components designed in this invention are general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. They can be fully implemented by those skilled in the art, so there is no need to elaborate.
