Description

Technical Field

[0001] The utility model relates to the technical field of precast concrete, in particular to a vibrating device for salt-alkali corrosion resistant square piles. Background Art

[0002] Concrete square piles are a type of pile foundation used in foundation engineering. They are quadrilateral columns made of concrete, usually square or rectangular, and their length can be customized as needed. Concrete square piles are mainly used for the foundation bearing of buildings, bridges, water conservancy projects, roads and other projects. The vibrating device transmits vibration to the concrete, rearranges the particles in the concrete, reduces the gaps, and thus improves the uniformity of the concrete.

[0003] In the related art, in order to improve the strength and corrosion resistance of square piles, steel keels with corrosion-resistant coatings on the outer surface are often added to the square piles to increase the service life of the square piles. However, when the commonly used vibrating devices vibrate the square pile concrete, the steel keels will be misaligned, thereby affecting the strength of the square pile after forming. Utility Model Content

[0004] In order to reduce the degree of displacement of the steel keel caused by vibrating the square pile concrete, and to help ensure that the strength of the square bricks after forming is not excessively reduced, the present application provides a vibrating device for salt-alkali corrosion-resistant square piles.

[0005] The present application provides a vibrating device for salt-alkali corrosion-resistant square piles, which adopts the following technical solution: it comprises a workbench, on which a mold bin is fixedly arranged, a pressing end block is slidably arranged in the mold bin, the pressing end block is used to abut against the end wall of the steel bar keel, a thrust spring is arranged between the end wall of the mold bin and the pressing end block, the thrust spring drives the pressing end block away from the end wall of the mold bin, a supporting frame is fixedly arranged on the workbench, a sliding frame is slidably arranged on the supporting frame, a screw is rotatably arranged on the supporting frame, the screw is threadedly connected to the sliding frame, a rotating motor for driving the screw to rotate is arranged on the supporting frame, a vibration motor is fixedly arranged on the sliding frame, a vibrating rod is arranged on the driving shaft of the vibration motor, and a frame frame is fixedly arranged on the end of the vibrating rod away from the sliding frame.

[0006] By adopting the above technical scheme, before the mold bin is filled with concrete, the steel bar keel is placed in the mold bin, so that the pressing end block and the side wall of the mold bin away from the pressing end block press against the two ends of the steel bar keel, so that the steel bar keel is firmly fixed in the mold bin, and the frame is put outside the steel bar keel, and the vibration motor is started. The vibration motor transmits the entire building to the frame through the vibrating rod. The frame vibrates the concrete, and the screw is driven to rotate by the rotating motor. The screw drives the sliding frame to slide along the length of the mold bin, so as to vibrate the concrete at various positions of the mold bin, thereby reducing the degree of displacement of the steel bar keel caused by vibrating the square pile concrete, which helps to ensure that the strength of the square brick after forming is not excessively reduced.

[0007] Preferably, a push block is provided on the sliding frame, and the push block can be abutted against the pressing end block.

[0008] By adopting the above technical solution, after the concrete in the mold bin is vibrated, the sliding frame is driven to slide and the push block is pushed away from the pressing end block, thereby driving the pressing end block to loosen the steel keel. After the pressing end block and the steel keel are loosened, the frame only vibrates the concrete at the position of the pressing end block, and the concrete at other positions supports the steel keel.

[0009] Preferably, the push block is slidably arranged on a sliding frame, a slow-push spring is arranged between the sliding frame and the push block, a frame-shaped groove is opened on the pressing end block, and the frame-shaped frame can be inserted into the frame-shaped groove.

[0010] By adopting the above technical solution, as the sliding frame approaches the pressing end block, one end of the push block pushes away the pressing end block, and the other end retracts into the sliding frame, so that the pressing end block loosens the steel keel while the frame frame is inserted into the frame groove. During the process of inserting the frame frame into the frame groove, the frame frame forces the concrete in the frame groove out of the frame groove, and the concrete forced out of the frame groove is supplemented to the position where the pressing end block leaves, so that the contact position between the steel keel and the pressing end block is covered with concrete.

[0011] Preferably, a hydraulic cylinder is fixedly provided on the sliding frame, a packaging plate is fixedly provided on the piston rod of the hydraulic cylinder, and the packaging plate can be inserted into the mold bin and is adapted to the shape of the mold bin.

[0012] By adopting the above technical solution, when the contact position between the steel keel and the pressing end block is covered, the hydraulic cylinder drives the sealing plate to be inserted into the mold bin, and the sealing plate blocks the flow of concrete in the mold bin, thereby completing the sealing of the other pile concrete.

[0013] Preferably, a guide rod is fixedly arranged on the pressing end block, the guide rod passes through and slides on the end wall of the mold bin, a travel switch is arranged on the workbench, the guide rod can be pressed against the travel switch, and the travel switch is connected with the solenoid valve controlling the hydraulic cylinder and the vibration motor signal.

[0014] By adopting the above technical solution, as the pressing end block slides, the guide rod on the pressing end block presses against the travel switch, the travel switch sends a feed command to the solenoid valve controlling the hydraulic cylinder, the hydraulic cylinder automatically drives the packaging plate to be inserted into the mold bin, and at the same time, the travel switch sends a stop command to the vibration motor, and the vibration motor stops working.

[0015] Preferably, the thrust spring is sleeved on the guide rod.

[0016] By adopting the above technical solution, the guiding property of the thrust spring during deformation is increased, the occurrence of the thrust spring being forced to pop out is avoided as much as possible, and the reliability of the device is improved.

[0017] Preferably, a leveling folding rod is rotatably provided on the sliding frame, and a smoothing roller is rotatably provided on one end of the leveling folding rod close to the mold bin.

[0018] By adopting the above technical solution, when the sliding frame slides, the sliding frame drives the smoothing roller to roll on the concrete surface in the mold bin through the leveling folding rod, thereby automatically smoothing the traces left by the vibrating rod sliding on the concrete surface.

[0019] Preferably, arc-shaped grooves are provided on the lower surfaces of both ends of the support frame, and guide rails are provided together with the arc-shaped grooves and the lower surface of the support frame. A roller is rotatably provided at one end of the leveling folding rod away from the leveling roller, and the roller rolls in the guide rail. A torsion spring is provided at the rotation connection between the leveling folding rod and the sliding frame, and the torsion spring drives the leveling folding rod away from the mold bin.

[0020] By adopting the above technical solution, when the sliding frame slides to the two end positions of the supporting frame, the roller enters the guide rail in the arc groove, and the torsion spring drives the smoothing roller to automatically lift up. When the sliding frame slides in the middle of the supporting frame, the guide rail on the lower surface of the supporting frame drives the smoothing roller to press down on the concrete surface in the mold bin, thereby realizing the automatic lifting of the smoothing roller when the concrete on the frame is not in the mold bin and is vibrated.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-2 This application is described in further detail.

[0029] The present application embodiment discloses a vibrating device for salt-alkali corrosion resistant square piles. Figure 1 and Figure 2 The invention comprises a workbench 1, on which a mold bin 2 is fixedly arranged, in which a pressing end block 21 is slidably arranged, and between the end wall of the mold bin 2 and the pressing end block 21, a thrust spring 22 is arranged, and the thrust spring 22 drives the pressing end block 21 away from the end wall of the mold bin 2. Before filling concrete, a steel keel is placed in the mold bin 2. The pressing end block 21 and the side wall of the mold bin 2 away from the pressing block are pressed against the two ends of the steel keel, and the thrust spring 22 drives the pressing end block 21 to apply a clamping force to the steel keel, thereby fastening the two ends of the steel keel in the mold bin 2.

[0030] Reference Figure 1 and Figure 2A support frame 3 is fixedly provided on the workbench 1, a sliding frame 31 is slidably provided on the support frame 3, a screw rod 32 is rotatably provided on the support frame 3, the screw rod 32 is threadedly connected to the sliding frame 31, a rotating motor 321 for driving the screw rod 32 to rotate is provided on the support frame 3, a vibration motor 311 is fixedly provided on the sliding frame 31, a vibrating rod 312 is provided on the driving shaft of the vibration motor 311, and a frame frame 313 is fixedly provided at one end of the vibrating rod 312 away from the sliding frame 31. When the two ends of the steel bar keel are fastened in the mold bin 2, the frame frame 313 is sleeved around the steel bar keel. Start the vibration motor 311, and the vibration motor 311 transmits vibration to the entire frame frame 313 through the vibrating rod 312. The frame frame 313 vibrates the concrete around the steel bar keel to eliminate bubbles in the concrete. At the same time, by starting the rotating motor 321, the screw 32 is driven to rotate, thereby pushing the sliding frame 31 to slide along the length direction of the mold bin 2, so that the frame frame 313 vibrates the square pile concrete at different positions. This reduces the degree of displacement of the steel keel caused by vibrating the square pile concrete, which helps to ensure that the strength of the square brick after forming is not excessively reduced.

[0031] In order to help the steel keel to be properly covered while the pressing end block 21 is moved to loosen the steel keel, refer to Figure 2 , a push block 314 is slidably provided on the sliding frame 31, and the push block 314 can be against the pressing end block 21. A slow push spring 315 is provided between the sliding frame 31 and the push block 314, and the elastic coefficient of the slow push spring 315 is close to the elastic coefficient of the thrust spring 22. A frame-shaped groove 211 is provided on the pressing end block 21, and the frame-shaped frame 313 can be inserted into the frame-shaped groove 211. As the sliding frame 31 gradually approaches the pressing end block 21. One end of the push block 314 overcomes the elastic force of the thrust spring 22 and pushes the pressing end block 21 away. At the same time, the other end overcomes the elastic force of the slow push spring 315, so that the push block 314 retracts into the sliding frame 31. Since the elastic coefficient of the slow push spring 315 is close to the elastic coefficient of the thrust spring 22, the frame-shaped frame 313 can be inserted into the frame-shaped groove 211 while the pressing end block 21 loosens the steel keel. During the process of inserting the frame 313 into the frame groove 211, the frame 313 squeezes out the concrete in the frame groove 211. The concrete squeezed out of the frame groove 211 will fill the position where the pressing end block 21 leaves, so that the contact position between the steel keel and the pressing end block 21 is covered with concrete. This process helps to properly cover the steel keel while moving the pressing end block 21 to loosen the steel keel, thereby ensuring the stability of the square pile structure and the uniform distribution of concrete as much as possible.

[0032] In order to automatically complete the sealing of the other pile concrete, thereby ensuring that the concrete is compactly sealed in the mold bin 2, refer to Figure 2, a hydraulic cylinder 316 is fixedly arranged on the sliding frame 31, and a packaging plate 317 is fixedly arranged on the piston rod of the hydraulic cylinder 316. The packaging plate 317 can be inserted into the mold bin 2 and is adapted to the shape of the mold bin 2. A guide rod 212 is fixedly arranged on the pressing end block 21, and the guide rod 212 penetrates and slides on the end wall of the mold bin 2, and the thrust spring 22 is sleeved on the guide rod 212. A travel switch 11 is arranged on the workbench 1, and the guide rod 212 can be pressed against the travel switch 11. The travel switch 11 is connected to the electromagnetic valve controlling the hydraulic cylinder 316 and the vibration motor 311. When the pressing end block 21 completes covering the steel bar keel, the guide rod 212 on the pressing end block 21 will touch the travel switch 11. The travel switch 11 will send a feed instruction to the electromagnetic valve controlling the hydraulic cylinder 316, and send a stop instruction to the vibration motor 311 to stop the vibration of the vibration motor 311. After the solenoid valve of the hydraulic cylinder 316 receives the feeding instruction, the hydraulic cylinder 316 starts the feeding action and drives the sealing plate 317 to be inserted into the mold chamber 2. Once the sealing plate 317 is inserted into the mold chamber 2, the sealing plate 317 will hinder the free flow of concrete in the mold chamber 2, so as to automatically complete the sealing of the other pile concrete, thereby ensuring that the concrete is compactly sealed in the mold chamber 2.

[0033] In order to automatically smooth the traces left by the vibrating rod 312 sliding on the concrete surface and improve the aesthetics of the square pile, refer to Figure 1 The lower surface of both ends of the support frame 3 is provided with an arc groove 34, and the arc groove 34 and the lower surface of the support frame 3 are provided with a guide rail 341. The end of the leveling folding rod 33 away from the smoothing roller 331 is provided with a roller 332, and the roller 332 rolls in the guide rail 341. The rotation connection between the leveling folding rod 33 and the sliding frame 31 is provided with a torsion spring 333, and the torsion spring 333 drives the leveling folding rod 33 away from the mold bin 2. When the sliding frame 31 slides in the middle of the support frame 3, the guide rail 341 on the lower surface of the support frame 3 will play a role in limiting the torsion spring 333. The guide rail 341 will drive the smoothing roller 331 to press down through the roller 332 and the leveling folding rod 33, and the smoothing roller 331 will roll on the concrete surface in the mold bin 2, thereby automatically smoothing the traces left by the vibration rod 312 sliding on the concrete surface. When the sliding frame 31 slides to the two ends of the support frame 3, the roller 332 enters the guide rail 341 in the arc groove 34. At this position, the support frame 3 releases the restriction on the torsion spring 333, and the torsion spring 333 drives the trowel roller 331 to automatically lift up. This helps the trowel roller 331 not to contact the concrete surface when the sliding frame 31 is located at the two ends of the support frame 3, reducing unnecessary friction and interference.

[0034] The implementation principle of a vibration device for salt-alkali corrosion-resistant square piles in the embodiment of the present application is as follows: before the mold bin 2 is filled with concrete, the steel bar keel is placed in the mold bin 2. The pressing end block 21 and the side wall of the mold bin 2 away from the pressing end block 21 press against the two ends of the steel bar keel to ensure that the steel bar keel is firmly fixed in the mold bin 2. The frame 313 is sleeved outside the steel bar keel, and the vibration motor 311 is started. The vibration is transmitted to the frame 313 through the vibrating rod 312, so that the frame 313 vibrates the concrete. Subsequently, the screw 32 is driven to rotate by the rotating motor 321, and the screw 32 drives the sliding frame 31 to slide along the length direction of the mold bin 2 to vibrate the concrete at each position of the mold bin 2. As the sliding frame 31 approaches the pressing end block 21, one end of the push block 314 presses against the pressing end block 21, and the other end retracts into the sliding frame 31. The frame 313 can be inserted into the frame groove 211 while the pressing end block 21 releases the steel keel. During the insertion process, the frame 313 squeezes the concrete in the frame groove 211 out of the frame groove 211, and the squeezed concrete fills the position where the pressing end block 21 leaves, covering the contact position between the steel keel and the pressing end block 21 with concrete. This reduces the degree of displacement of the steel keel caused by vibrating the square pile concrete, which helps to ensure that the strength of the square brick after forming is not excessively reduced.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
