Description

Technical Field

[0001] This application relates to the field of vibration equipment technology, and in particular to an immersion vibratory device for pouring the heavy-duty ring beam of the main structure of a large stadium. Background Technology

[0002] During the pouring of the main structure of large stadiums, immersion vibrators are needed to compact the poured concrete using a quick-insertion, slow-extraction method. Existing immersion vibrators include a vibrator rod containing an excitation component. The drive unit can be located inside the vibrator rod or outside it, connected to the excitation component via a flexible transmission mechanism within a hose. The drive mechanism drives the excitation component to vibrate, which in turn vibrates the vibrator rod. The vibrator rod is then manually inserted into the concrete by holding the hose, thus compacting the concrete.

[0003] However, in the process of vibrating large-scale cast-in-place structures, the insertion resistance of the vibrator increases when the hose drives the vibrating rod to insert into the deep concrete. The hose is prone to bending, causing the insertion direction of the vibrator to deviate. The vibrator is difficult to accurately reach the target layer. In layered vibration, the vibrator needs to be inserted to the rated depth of the lower layer of concrete to eliminate the layer joint. Therefore, the deviation and tilt of the vibrator can easily lead to inaccurate positioning depth, affecting the vibration quality. Moreover, as the insertion depth increases, the length of the hose between the gripping position and the vibrator increases, and the hose is more prone to bending. It is difficult to provide the force required for the vibrator to quickly insert into the concrete, resulting in a decrease in vibration efficiency and vibration quality. Summary of the Invention

[0004] This application proposes an immersion vibratory compaction device for casting the super-heavy ring beam of the main structure of a large stadium. It has the advantage that the vibratory rod can be inserted to the target layer depth under balanced thrust, which solves the problem that the holding hose is prone to bending, affecting the insertion speed and the insertion posture of the vibratory rod.

[0005] To achieve the above objectives, this application adopts the following technical solution: an immersion vibratory compaction device for casting the super-heavy ring beam of the main structure of a large stadium, comprising a vibratory rod, a flexible tube fixedly connected to the top of the vibratory rod near the midpoint, a connecting sleeve plate fixedly sleeved on the top of the flexible tube, an adjustment mechanism provided on one side of the vibratory rod, the adjustment mechanism comprising a movable plate, a plurality of elastic adjustment elements fixedly connected to the bottom of the movable plate, the elastic adjustment elements being fixedly connected to the vibratory rod, and the plurality of elastic adjustment elements cooperating to provide uniform thrust to the vibratory rod.

[0006] The adjustment mechanism is used to limit the distance between the moving plate and the connecting sleeve plate, so that the flexible tube and the elastic adjustment component can work together to elastically position the vibrator. The adjustment mechanism can drive the moving plate and the connecting sleeve plate to rotate horizontally at the corresponding angle according to the decrease in the distance between the vibrator and the moving plate.

[0007] Furthermore, the adjustment mechanism also includes a movable seat, and a plurality of the elastic adjustment members are arranged in a ring at uniform intervals. A connecting column is slidably sleeved on one side of the connecting sleeve plate, a movable block is fixedly connected to the bottom of the connecting column, a connecting rod is fixedly connected to the bottom of the movable block, and the connecting rod is fixedly connected to the movable plate.

[0008] Furthermore, it also includes a bracket, the movable seat is slidably connected to the bracket, a drive motor is fixedly installed on one side of the bottom of the bracket, the output end of the drive motor is drivenly connected to a lifting screw, and the lifting screw is threadedly sleeved with the movable seat.

[0009] Furthermore, the adjustment mechanism also includes a drive shaft, which is rotatably connected to the movable seat. A connecting seat is fixedly sleeved on the top of the drive shaft, and the connecting seat is fixedly sleeved on the connecting column. An adjusting rack is slidably sleeved on one side of the movable seat. An arc-shaped plate is fixedly connected to one side of the top of the adjusting rack, and an arc-shaped groove is formed on one side of the arc-shaped plate. An adjusting block is fixedly connected to one side of the connecting plate, and the adjusting block is slidably sleeved in the arc-shaped groove. A return spring is movably sleeved on the outside of the connecting column. A transmission connection mechanism is provided at the bottom of the movable seat. The upward movement of the adjusting rack relative to the movable seat can drive the drive shaft to reciprocate through the transmission connection mechanism.

[0010] Furthermore, the transmission connection mechanism includes a one-way transmission mechanism. A reversing screw is rotatably provided on one side of the bottom of the movable seat. One end of the reversing screw is fixedly connected to the ratchet gear in a coaxial manner. A transmission rack is slidably provided on one side of the bottom of the movable seat. A moving block is fixedly connected to one end of the transmission rack. The moving block is threadedly sleeved with the reversing screw. A transmission gear is fixedly connected to the bottom of the transmission shaft. The transmission gear and the transmission rack mesh with each other. An adjusting rod is fixedly connected to the bottom of the connecting sleeve plate near the middle position.

[0011] Furthermore, the one-way transmission mechanism includes an adjusting gear and a ratchet gear. The adjusting gear meshes with the adjusting rack. A pawl is rotatably provided on the top of the adjusting gear. A stop spring is fixedly connected to one side of the pawl. The adjusting gear, together with the pawl and the stop spring, can drive the ratchet gear to rotate synchronously in one direction, and the rotation direction is adapted to the upward direction of the adjusting rack.

[0012] Furthermore, several limiting blocks are fixedly installed at the bottom of the movable plate, and the top diameter of the vibrating rod is reduced and part of it is located inside the limiting blocks.

[0013] Furthermore, the bottom of the movable plate is provided with several electromagnets, which are arranged in a ring at uniform intervals. The electromagnets are fixedly connected to the corresponding limiting blocks. The top of the vibrating rod is fixedly provided with several permanent magnets, and the force between the permanent magnets and the electromagnets is a repulsive force.

[0014] Furthermore, a contact switch is fixedly installed on one side of the top of the movable seat, the position of which corresponds to the position of the adjusting rack, and the electromagnet is electrically connected to the contact switch.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This application provides an immersion vibratory compaction device for pouring heavy-duty ring beams in the main structure of a large stadium. A flexible tube pulls the vibratory rod, which, in conjunction with the elastic connector between the vibratory rod and the moving plate, maintains the distance between the vibratory rod and the moving plate within a specified range through uniform elastic force. During the vibration of a large concrete pouring structure, the moving plate is driven vertically by the moving seat, and the elastic force of the elastic connector allows the vibratory rod to be more easily inserted into the deep concrete. This facilitates rapid and accurate insertion of the vibratory rod. Furthermore, the multiple elastic elements, through elastic force balance, more easily ensure that the vibratory rod as a whole remains within the specified tilt range in the vertical direction, thus improving the quality of vibration of the large concrete pouring structure.

[0017] 2. This application provides an immersion vibratory compaction device for casting heavy-duty ring beams in the main structure of large stadiums. Through an elastic adjustment component, a buffer space is provided. When the vibratory rod encounters reinforcing steel during insertion, the movement of the vibratory rod is obstructed, and the distance between it and the moving plate decreases. After the distance decreases to the rated value, the adjustment rod is driven by the vibratory rod to move relative to the moving seat. This, in conjunction with the adjusting rack and unidirectional transmission mechanism, drives the reversing screw to rotate in one direction. This, in turn, works with the moving block, transmission rack, and transmission gear to drive the transmission shaft to rotate and reciprocate. The transmission shaft then drives the flexible tube and the moving plate to swing horizontally synchronously, thus achieving automatic avoidance and ensuring the continuity of the vibratory rod insertion and compaction process. This further improves the reliability of the vibratory compaction device and is suitable for precise layered vibration of large concrete casting structures and environments with dense reinforcement.

Detailed Implementation

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

[0027] Example 1, as Figures 1-5 An immersion vibratory compaction device for casting a heavy-duty ring beam in the main structure of a large stadium includes a vibratory rod 2. A flexible tube 3 is fixedly connected to the top of the vibratory rod 2 near its midpoint. A connecting sleeve 5 is fixedly sleeved on the top of the flexible tube 3. A connecting column 4 is slidably sleeved on one side of the connecting sleeve 5. The connecting sleeve 5 can slide axially relative to the connecting column 4. A movable block 6 is fixedly connected to the bottom of the connecting column 4. A connecting rod 8 is fixedly connected to the bottom of the movable block 6. A movable plate 9 is fixedly connected to the bottom of the connecting rod 8. (See reference...) Figure 4Several elastic adjustment elements 10 are fixedly connected to the bottom of the movable plate 9. The elastic adjustment elements 10 are springs or spring telescopic rods. The bottom of the elastic adjustment elements 10 is fixedly connected to the vibrator 2. The elastic adjustment elements 10 are in a compressed state, that is, the elastic adjustment elements 10 provide a thrust to push the vibrator 2 away from the movable plate 9. Several elastic adjustment elements 10 are arranged in a ring with uniform intervals. The distance between the several elastic adjustment elements 10 and the flexible tube 3 is consistent. The flexible tube 3 is in a straightened state. The flexible tube 3 provides a pulling force that pulls the vibrator 2 in the opposite direction to the elastic force of the elastic adjustment elements 10. The several elastic adjustment elements 10 cooperate to provide a uniform thrust to push the vibrator 2 into the concrete. The flexible tube 3 is located inside the movable plate 9.

[0028] When the vibrator 2 is inserted into the concrete, the connecting column 4 descends, which in turn causes the movable block 6 to descend. The movable block 6 then causes the connecting rod 8 to descend, which in turn causes the moving plate 9 to descend. This causes the moving plate 9 to tend to move closer to the vibrator 2, meaning that the elastic adjustment element 10 tends to be further compressed. Consequently, the moving plate 9 causes the elastic adjustment element 10 to move and descend. The elastic adjustment element 10 pushes the vibrator 2 downward through its elastic force. The vibrator 2 vibrates the nearby concrete, and the multiple elastic adjustment elements 10 balance the forces on the top surface of the vibrator 2, thus keeping the vibrator 2 in a vertical position. The upward movement provides additional elastic force to drive the vibrator 2 downward. Combined with the self-weight of the vibrator 2, the vibrator 2 can be more easily inserted into the deep part of the concrete. This ensures the insertion rate of the vibrator 2 into the deep concrete while maintaining the insertion posture of the vibrator 2, thereby ensuring the vibration effect of the vibrator 2. The connecting column 4 drives the vibrator 2 to be inserted into the target depth range. When performing layered vibration, the elastic adjustment component 10 drives the vibrator 2 to be inserted into the rated depth range of the lower layer of concrete. This ensures the pouring and vibration quality of the main structure of the large stadium without affecting the vibration of the vibrator 2.

[0029] It also includes a support 1, which is placed flat on the support structure. A movable seat 12 is slidably mounted on one side of the support 1. The movable seat 12 can slide vertically up and down relative to the support 1 without detaching from the support 1. A drive motor 28 is fixedly mounted on one side of the bottom of the support 1. The output end of the drive motor 28 is connected to a lifting screw 29. The lifting screw 29 is threadedly connected to the movable seat 12. The movable seat 12 is used to drive the connecting column 4 to rise and fall vertically. When vibrating concrete, the drive motor 28 drives the lifting screw 29 to rotate. The rotation of the lifting screw 29 drives the movable seat 12 to rise and fall. The movable seat 12 is connected to the drive belt. When the movable connecting column 4 is raised and lowered, and the vibrator 2 is pulled out of the concrete, the connecting column 4 rises, the connecting sleeve 5 is located at the bottom of the connecting column 4, the connecting column 4 drives the movable block 6 to rise, the movable block 6 drives the connecting sleeve 5 to rise, the connecting sleeve 5 drives the flexible tube 3 to rise, and the flexible tube 3 drives the vibrator 2 to rise relative to the support 1. At this time, the movable block 6 drives the connecting rod 8 and the moving plate 9 to rise synchronously with the vibrator 2 until the vibrator 2 is pulled out of the concrete. The lifting screw 29 drives the moving seat 12 to move vertically to ensure accurate movement direction and further avoid the vibrator 2 from moving skewed, ensuring that the vibrator 2 can be inserted into the target layer depth.

[0030] In the pouring system of the main body of a large venue, the concrete is poured deep and the reinforcement is dense. There may be steel bars blocking the downward direction of the vibrator 2, which means that the vibrator 2 needs to be pulled out and repositioned for re-vibration.

[0031] Example 2, as Figures 1-6 Based on Embodiment 1, a drive shaft 13 is rotatably mounted on one side of the movable seat 12. A connecting seat 14 is fixedly sleeved on the top of the drive shaft 13. The connecting seat 14 is fixedly sleeved with the connecting post 4. The connecting post 4 can rotate around the axis of the drive shaft 13. (See reference...) Figure 3 An adjusting rack 16 is slidably sleeved on one side of the movable seat 12. The adjusting rack 16 can slide and rise relative to the movable seat 12. An arc plate 17 is fixedly connected to one side of the top of the adjusting rack 16. The side wall of the arc plate 17 is an arc surface with its axis collinear with the axis of the transmission shaft 13. An arc groove 18 is opened on one side of the arc plate 17. An adjusting block 19 is fixedly connected to one side of the connecting sleeve plate 5. The adjusting block 19 is slidably sleeved in the arc groove 18. When the connecting column 4 rotates around the transmission shaft 13, the connecting column 4 drives the connecting sleeve plate 5 to rotate, and the connecting sleeve plate 5 drives the adjusting block 19 to slide along the arc groove 18.

[0032] A one-way transmission mechanism 7 is provided on one side of the bottom of the movable base 12. The one-way transmission mechanism 7 includes an adjusting gear 701 and a ratchet 702. The ratchet 702 is located inside the adjusting gear 701. (See reference...) Figure 6The adjusting gear 701 meshes with the adjusting rack 16. A pawl 703 is rotatably mounted on the top of the adjusting gear 701. A stop spring 704 is fixedly connected to one side of the pawl 703. The stop spring 704 pushes the pawl 703 to engage with the teeth of the ratchet 702, thereby unidirectionally restricting the rotation of the ratchet 702 relative to the adjusting gear 701. The adjusting gear 701, together with the pawl 703 and the stop spring 704, can unidirectionally drive the ratchet 702 to rotate synchronously, and the direction of rotation is adapted to the upward direction of the adjusting rack 16. A reversing screw 20 is rotatably mounted on one side of the bottom of the moving base 12. One end of the reversing screw 20 is fixedly connected to the ratchet 702 in a coaxial manner. A transmission rack 22 is slidably mounted on one side of the bottom of the moving base 12.

[0033] The transmission rack 22 is arranged in a direction parallel to the axis of the reversing screw 20. One end of the transmission rack 22 is fixedly connected to a moving block 21. The moving block 21 is threadedly connected to the reversing screw 20. The unidirectional rotation of the reversing screw 20 can drive the moving block 21 to move axially back and forth. The bottom of the transmission shaft 13 is fixedly connected to a transmission gear 23. The transmission gear 23 and the transmission rack 22 mesh with each other. An adjusting rod 11 is fixedly connected to the bottom of the connecting sleeve 5 near the middle position. The bottom of the adjusting rod 11 passes through the moving plate 9 and is located at the bottom of the moving plate 9. A return spring 15 is movably sleeved on the outside of the connecting column 4. The return spring 15 pushes the connecting sleeve 5 closer to the moving block 6.

[0034] When the moving plate 9, in conjunction with the elastic adjusting member 10, drives the vibrator 2 to descend and the bottom of the vibrator 2 contacts the reinforcement of the cast structure, the reinforcement restricts the descent of the vibrator 2. The moving plate 9 continues to descend, and the elastic adjusting member 10 is further compressed by the moving plate 9. The connecting column 4, in conjunction with the return spring 15, drives the connecting sleeve 5 to approach the vibrator 2. The connecting sleeve 5 drives the adjusting rod 11 to move closer to the vibrator 2 until it contacts the vibrator 2. The vibrator 2 restricts the continued descent of the adjusting rod 11. The adjusting rod 11 drives the connecting sleeve 5 to slide relative to the connecting column 4. The connecting sleeve 5 drives the adjusting block 19 to move vertically relative to the moving seat 12. The adjusting block 19 abuts against the inner wall of the arc groove 18, driving the arc plate 17 to rise relative to the moving seat 12. The adjusting gear 701, the reversing screw 20, the transmission rack 22, the transmission shaft 13, and the moving seat 12 move synchronously, thereby the arc plate 17 drives the adjusting rack 16 to move relative to the adjusting gear 701.

[0035] The adjusting rack 16 drives the adjusting gear 701 to rotate, which in turn drives the ratchet 702 to rotate. The ratchet 702 drives the reversing screw 20 to rotate, which in turn drives the moving block 21 to move axially. This causes the transmission rack 22 to move relative to the transmission gear 23, which in turn drives the transmission gear 23 to rotate. Consequently, the transmission gear 23 drives the transmission shaft 13 to rotate, which in turn drives the connecting seat 14 to rotate. The connecting seat 14, in conjunction with the connecting column 4, the movable block 6, and the connecting rod 8, drives the moving plate 9 to rotate. The moving plate 9 causes the flexible tube 3 to swing, thereby causing the vibrator 2 to move away from the reinforcement position to achieve automatic repositioning. With the further compressed elastic adjusting element 10, the position of the vibrator 2 is adjusted. The elastic adjusting element 10 then resets, and the adjusting rack 16 descends relative to the adjusting gear 701, while the ratchet 702 remains stationary. This ensures continuous operation of the vibration work in the densely reinforced area and further improves the reliability of the vibration device.

[0036] Example 3, as Figures 1-5 Based on Embodiment 2, the vibrating rod 2 is configured as a vibrating assembly with a built-in drive mechanism. The drive assembly of the vibrating rod 2 can also be fixedly mounted on the top of the connecting seat 14 and connected to the vibrating rod 2 through the flexible tube 3 via a flexible transmission mechanism. Several limiting blocks 25 are fixedly mounted on the bottom of the moving plate 9. The limiting blocks 25 are arranged in a ring at even intervals. The top diameter of the vibrating rod 2 is reduced and part of it is located inside the limiting blocks 25. The limiting blocks 25 are used to limit the swing range of the vibrating rod 2. During the avoidance process, the limiting blocks 25 can drive the vibrating rod 2 to ensure forced horizontal displacement within the rated tilt angle range for avoidance, ensuring the reliability of the vibrating device. See reference. Figure 3 A contact switch 24 is fixedly installed on one side of the top of the movable base 12, the position of which corresponds to the position of the adjusting rack 16, and several electromagnets 27 are installed at the bottom of the movable plate 9.

[0037] Several electromagnets 27 are arranged in a ring at uniform intervals. Each electromagnet 27 is fixedly connected to a corresponding limit block 25. Each electromagnet 27 is electrically connected to a contact switch 24. (See reference) Figure 4Several permanent magnets 26 are fixedly installed on the top of the vibrating rod 2. The number and position of the permanent magnets 26 are adapted to the number and position of the electromagnets 27. The force between the permanent magnets 26 and the electromagnets 27 is a repulsive force. When the vibrating rod 2 is restricted from moving due to the reinforcement, the adjusting rod 11 drives the adjusting rack 16 to rise relative to the moving seat 12 until it contacts the contact switch 24. The contact switch 24 is activated, so that the electromagnets 27 are connected to the circuit and provide lateral thrust. When the moving plate 9 has a tendency to move horizontally relative to the vibrating rod 2, the several electromagnets 27 cooperate with the corresponding permanent magnets 26 to keep the limiting block 25 as close as possible to the middle of the moving plate 9 before it contacts the vibrating rod 2, thereby improving the response rate of the automatic avoidance of the vibrating rod 2 and further improving the reliability of the vibrating device.
