Description

Technical Field

[0001] The present application relates to the technical field of concrete vibrating equipment, and in particular to a vibrating device for pouring concrete for aluminum formwork construction. Background Art

[0002] Vibration can eliminate bubbles and pores in concrete and improve density and strength. Therefore, vibration operation is an indispensable part of concrete pouring.

[0003] Because the vibrator must be held in hand, the operator must stand or bend for long periods of time and frequently move the equipment, which requires high arm strength and endurance in the waist and abdominal muscles. Furthermore, because the vibrator generates high-frequency vibrations (for example, planetary vibrators can reach frequencies exceeding 200Hz), the operator must resist the vibration reaction force, which can easily cause fatigue.

[0004] Secondly, aluminum formwork has low structural strength and is prone to deformation. Prolonged vibration can easily cause it to shift or deform. Therefore, when pouring aluminum formwork, layered and secondary vibrations are required, significantly increasing the workload. To ensure construction quality, it is essential to reduce the operator's workload during vibration operations. Summary of the Invention

[0005] This application proposes a vibrating device for pouring concrete for aluminum formwork construction. The most laborious pulling out and holding actions are automatically performed by the equipment, which can effectively save the physical strength of the workers. At the same time, it can ensure that the spacing between each vibration point is within the optimal distance, ensuring that each vibration point has better vibration efficiency.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a vibrating device for pouring concrete for aluminum formwork construction, comprising a vibrating rod, which is connected to a vibrating motor through a flexible shaft, and further comprising:

[0007] The support frame is provided with two groups, the tops of the two support frames are connected into a whole by a crossbeam, the support frame is movably connected to the crossbeam through a turntable, the crossbeam is hinged to the turntable, and a placement plate is provided at the bottom of the support frame;

[0008] A lifting frame, the lifting frame includes a lifting plate, the lifting plate is fixedly connected to a hanger, the hanger is fixedly connected to a lifting rope, the lifting rope is transmission-connected to a driving member, the driving member controls the lifting of the lifting plate, and a pipe sleeve is provided in the center of the lifting plate;

[0009] The upper end of the vibrating rod is fixedly connected with a pipe clamp, and the pipe sleeve supports the vibrating rod through the pipe clamp, and the lifting plate is lifted and lowered to carry the vibrating rod through the center of the placement plate.

[0010] Furthermore, the lifting plate is connected to the pipe sleeve via an elastic connecting block. The bottom of the pipe clamp is provided with an elastic cushioning pad. The cushioning pad is truncated cone-shaped, with a bottom diameter smaller than the inner diameter of the pipe sleeve and a top diameter larger than the diameter of the pipe sleeve. To ensure that the pipe clamp secures the vibrator, the pipe clamp has a high rigidity. Constant friction with the pipe sleeve during vibration of the vibrator would reduce the service life of the pipe sleeve. The cushioning pad prevents direct contact between the pipe sleeve and the clamp, reducing friction between the two and also providing a buffer.

[0011] Furthermore, a rope hole is provided in the middle of the mounting platform and the turntable, a fixed pulley is provided on the top of the turntable, the lifting rope passes through the rope hole and around the fixed pulley and is connected to the driving member, and the driving member is provided in the middle of the beam.

[0012] Furthermore, the suspension rope is provided with an elastic protrusion, which can be stuck in the gap between the fixed pulley and the crossbeam and can also be pulled out.

[0013] Furthermore, the inner wall of the tube sleeve and the outer wall of the buffer pad are respectively provided with a hook surface and a suede surface of Velcro.

[0014] Furthermore, a sensor is provided on the fixed pulley, which is used to detect the rotation state of the fixed pulley. When the fixed pulley stops rotating after rotating, a countdown of K seconds begins. After the countdown ends, the driving member starts to pull up the lifting plate. One of the two sensors triggers the driving member to rotate clockwise, and the other triggers the driving member to rotate counterclockwise.

[0015] Furthermore, in order to save more effort in shifting the position of the support frame, force rods are provided at both ends of the crossbeam, and the force rods have force sleeves extending outward.

[0016] Furthermore, the force adding rod includes a connecting block, an end portion of the connecting block is provided with an inserting rod, and the force adding sleeve can be inserted into the inserting rod.

[0017] Furthermore, the connecting block is hinged to the crossbeam, and the connecting block can be rotated to make the insertion rods on both sides inward or opposite to each other. Elastic sleeves are provided at both ends of the force sleeve, and a limit column is provided on the side of the force sleeve. A telescopic pin is provided at the position of the crossbeam corresponding to the limit column, and a wedge block is provided at the bottom of the telescopic pin. When the connecting block is rotated outward 180 degrees, the limit column passes over the telescopic pin and jams the limit column.

[0018] The beneficial effects of the present invention are as follows:

[0019] The present application provides a vibrating device for pouring concrete for aluminum formwork construction. The operator only needs to place the support frame and insert the vibrating rod. The most laborious pulling out and holding actions are automatically performed by the equipment, which can effectively save the worker's physical strength.

[0020] When moving the support frame, use the beam as the radius and another support frame as the center of the circle to ensure that the spacing between each vibration point is within the optimal distance, and ensure that each vibration point has better vibration efficiency, while improving work efficiency and quality, and reducing the number of vibrations.

[0021] The vibrating rod is always protected by the pipe sleeve, which prevents the vibrating rod from contacting the steel bars and effectively isolates the vibration force of the vibrating rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1, as Figures 1-4 A vibrating device for pouring concrete for aluminum formwork construction includes a vibrating rod 1 and a support frame 2. The vibrating rod 1 is connected to the vibrating motor through a flexible shaft. The vibrating rod 1 is inserted into the cement slurry for vibration. The support frame 2 is provided with two groups. The support frame 2 includes a placement plate 21, a tripod 22 and a mounting platform 23. The placement plate 21 is directly placed on the cement slurry or on the steel cage and the vibration port reserved for the aluminum formwork. The diameter of the placement plate 21 is large enough. When placed directly on the cement slurry, it will not be immersed in the cement slurry due to vibration, and it will not fall from the net port when placed on the steel cage. The placement plate 21 is connected to the mounting platform 23 through the tripod 22. The middle part of the plate 21 is provided with an opening, and a lifting frame 3 is provided at the opening. The lifting frame 3 includes a lifting plate 31, the lifting plate 31 is fixedly connected to a hanger 32, the hanger 32 is fixedly connected to a suspension rope 33, and the other end of the suspension rope 33 is connected to a driving member 8 after passing through a fixed pulley 34. The fixed pulley 34 is located just above the center of the lifting plate 31 to ensure that the lifting plate 31 and the suspension rack 32 can be lifted vertically. In this embodiment, the driving member 8 is a winch connected to a motor. In other embodiments, the driving member 8 can also be a mobile trolley driven by a motor. The driving member 8 pulls the lifting plate 31 up and down through the suspension rope 33, and the center of the lifting plate 31 is A pipe sleeve 36 is provided, and a pipe clamp 4 is fixedly connected to the upper end of the vibrating rod 1. The pipe clamp 4 consists of two half rings, which clamp the shell of the vibrating rod 1 after tightening. The diameter of the pipe clamp 4 is large enough or wide enough and cannot pass through the pipe sleeve 36. When the lifting plate 31 is lifted, it can move upward with the vibrating rod 1. The diameter of the lifting plate 31 is large enough that it will not be immersed in the cement slurry due to vibration. At the same time, it can also prevent the vibrating rod 1 from tilting. The lifting plate 31 is connected to the pipe sleeve 36 through an elastic connecting block to reduce the transmission of the vibration energy of the vibrating rod 1 to the lifting plate 31, reducing the vibration of the lifting plate 31, and the two support frames 2 are connected by a crossbeam 7. As a whole, the support frame 2 is movably connected to the beam 7 through the turntable 6, and the beam 7 is hinged to the turntable 6. The beam 7 has multiple length specifications or the length can be adjusted to accommodate different types of vibrating rods 1. The rotating shaft of the beam 7 is stuck on the turntable 6 to facilitate the replacement of the beam 7. The driving member 8 is arranged in the middle of the beam 7, the rope hole 24 passes through the mounting platform 23 and the turntable 6, and the fixed pulley 34 is arranged above the turntable 6. The driving member 8 includes two capstans, and the two capstans are connected to the motor through a one-way bearing. When the motor rotates, it drives a lifting plate 31 to move upward, and the lifting speed of the lifting plate 31 is about 0.1m / s.

[0032] The bottom of the pipe clamp 4 is provided with an elastic buffer pad 5. The diameter of the bottom of the buffer pad 5 is smaller than the inner diameter of the pipe sleeve 36, and the diameter of the top of the buffer pad 5 is larger than the diameter of the pipe sleeve 36. In order to ensure that the pipe clamp 4 clamps the vibrating rod 1, the pipe clamp 4 has a relatively large stiffness. When the vibrating rod 1 vibrates, it constantly rubs against the pipe sleeve 36, which will reduce the service life of the pipe sleeve 36. The buffer pad 5 makes the pipe sleeve 36 not directly contact the pipe clamp 4, reducing the friction between the two and also buffering.

[0033] When pouring the first layer, the distance between the concrete surface and the steel reinforcement cage is relatively high. The lifting frame 3 lands on the cement slurry surface and is far from the upper end of the steel reinforcement cage. It is difficult to insert the vibrating rod 1 into the pipe sleeve 36 through the steel reinforcement cage. Since one motor drives two winches simultaneously, when one lifting frame 3 is lifted, the other will descend. Therefore, it is necessary to make the lifting frame 3 on the other side descend with a time delay. In order to ensure that both lifting frames 3 are in the lifting state and facilitate the insertion of the vibrating rod 1 into the pipe sleeve 36, an elastic protrusion 35 is provided on the lifting rope 33. The protrusion 35 can be stuck by the gap between the fixed pulley 34 and the crossbeam 7 and can also be pulled out. When the winch relaxes the lifting rope 33, it ensures that the lifting frame 3 will not fall. After the vibrating rod 1 is inserted into the pipe sleeve 36, after pulling the protrusion 35 out of the gap, the lifting frame 3 can descend normally without interfering with the insertion of the vibrating rod 1 into the cement slurry.

[0034] After the protrusion 35 is pulled through the gap, if the distance from the cement slurry surface is too far, the lifting frame 3 may separate from the vibrating rod 1 and fall onto the cement slurry surface. In order to ensure the synchronous descent of the vibrating rod 1 and the lifting frame 3, the inner wall of the pipe sleeve 36 and the outer wall of the buffer pad 5 are respectively provided with the hook surface and the fluff surface of the magic tape. When the buffer pad 5 is placed in the pipe sleeve 36, the lifting frame 3 is not separated from the vibrating rod 1.

[0035] To achieve the automatic control of the driving member 8, a sensor is provided on the fixed pulley 34. The sensor is used to detect the rotation state of the fixed pulley 34. When the fixed pulley 34 rotates and then stops rotating, a countdown starts. After the countdown ends, the driving member 8 starts. The countdown is K seconds, 20 < K < 30. The stop rotation of the fixed pulley 34 indicates that the vibrating rod 1 is inserted in place. The monitoring of the rotation of the fixed pulley 34 excludes the rotation for a short time and the rotation caused by the rotation of the driving member 8. For example, the rotation duration of actively pulling the fixed pulley 34 out of the gap is relatively short and is regarded as non-rotation. One of the two sensors triggers the driving member 8 to rotate clockwise, and the other triggers the driving member 8 to rotate counterclockwise.

[0036] During vibration, first place the support frame 2 in place, insert the vibrating rod 1 into the pipe sleeve 36, pull down the lifting rope 33, pull the protrusion 35 out of the gap between the fixed pulley 34 and the crossbeam 7, and control the speed of the lifting frame 3 and the vibrating rod 1 into the cement slurry through the flexible shaft. After the vibrating rod 1 is inserted into the cement slurry, lift the other support frame 2, rotate it around the vibrating support frame 2, and switch to the next vibration point. After the set vibration time is reached, the driving member 8 is started to evenly lift the lifting frame 3, and the vibrating rod 1 is pulled out of the cement slurry at a uniform speed. After the lifting frame 3 rises to place, the vibrating rod 1 is pulled out and inserted into another lifting frame 3 that is in place, and the above process is repeated.

[0037] See also Figure 4-Figure 6 In order to save effort in shifting the position of the support frame 2, force rods 9 are provided at both ends of the crossbeam 7. The force rods 9 extend outward. When lifting the support frame 2, the lever can be reused. The force rod 9 includes a connecting block 91 and a force sleeve 94. The force rods 9 on both sides share a force sleeve 94. An insertion rod is provided at the end of the connecting block 91. When the support frame 2 needs to be lifted, the force sleeve 94 is put on the connecting block 91. When not in use, the force sleeve 94 can be folded up to reduce space occupation.

[0038] The connecting block 91 is hinged to the crossbeam 7. When not in use, the connecting blocks 91 on both sides are rotated to make the insertion rods on both sides face inward. Elastic sleeves 95 with elasticity are provided at both ends of the force sleeve 94. The elastic sleeves 95 center the force sleeve 94 to prevent the force sleeve 94 from falling.

[0039] A limiting column 92 is provided on the side of the force sleeve 94, and a telescopic pin 93 is provided at the position of the limit column 92 of the cross beam 7 corresponding to the limit column 92. A wedge block is provided at the bottom of the telescopic pin 93. When the connecting block 91 rotates 180 degrees, the limiting column 92 passes over the telescopic pin 93, and the telescopic pin 93 clamps the limiting column 92 to limit the rotation of the connecting block 91, so that the force sleeve 94 can exert force. When the device needs to be folded up, the telescopic pin 93 is pushed upward and the connecting block 91 is rotated so that the rods on both sides are facing inward, and the two ends of the force sleeve 94 are sleeved on the rods.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
