Description

Technical Field

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

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

[0003] Since the vibrator needs to be held in hand, the operator needs to stand or bend for a long time and move the equipment frequently, which requires high arm strength and waist and abdominal muscle endurance. In addition, since the vibrator generates high-frequency vibration during operation (for example, the vibration frequency of a planetary vibrator is above 200Hz), the operator needs to resist the vibration reaction force, which can easily make the operator feel tired.

[0004] Secondly, since the aluminum formwork has a low structural strength and is easy to deform, long vibration time can easily cause the aluminum formwork to shift or deform. Therefore, when pouring the aluminum formwork, layered vibration and secondary vibration are required, which greatly increases the workload of vibration. In order to ensure the construction quality, it is necessary to reduce the work intensity of the operator during the vibration operation. Summary of the invention

[0005] The present application proposes a vibrating device for pouring concrete in 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 a 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, the vibrating rod is connected to a vibrating motor through a flexible shaft, and further comprising: 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; A lifting frame, the lifting frame comprises a lifting plate, the lifting plate is fixedly connected to a hanger, the hanger is fixedly connected to a hanging rope, the hanging rope is transmission-connected to a driving member, the driving member controls the lifting of the lifting plate, and a pipe sleeve is provided at the center of the lifting plate; The upper end of the vibrating rod is fixedly connected with a pipe clamp, and the pipe sleeve holds up 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.

[0007] Further, the lifting plate is connected to the pipe sleeve through an elastic connecting block, and an elastic buffer pad is provided at the bottom of the pipe clamp. The buffer pad is frustum-shaped, the diameter of the bottom of the buffer pad is smaller than the inner diameter of the pipe sleeve, and the diameter of the top of the buffer pad is larger than the diameter of the pipe sleeve. To ensure that the pipe clamp clamps the vibrating rod, the pipe clamp has a relatively large stiffness. When the vibrating rod vibrates, it continuously rubs against the pipe sleeve, which will reduce the service life of the pipe sleeve. The buffer pad prevents the pipe sleeve from directly contacting the pipe clamp, reduces the friction between the two, and can also buffer.

[0008] Further, a rope hole is provided in the middle of the mounting table and the turntable, a fixed pulley is provided at the top of the turntable, the lifting rope passes through the rope hole and bypasses the fixed pulley and then is connected to the driving member, and the driving member is provided in the middle of the cross beam.

[0009] Further, an elastic protrusion is provided on the lifting rope. The protrusion can be caught by the gap between the fixed pulley and the cross beam and can also be pulled out.

[0010] Further, the inner wall of the pipe sleeve and the outer side wall of the buffer pad are respectively provided with the hook surface and the flannelette surface of the magic tape.

[0011] Further, a sensor is provided on the fixed pulley. The sensor is used to detect the rotation state of the fixed pulley. When the fixed pulley rotates and then stops rotating, a countdown of K seconds starts. After the countdown ends, the driving member is activated 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.

[0012] Further, in order to make it more labor-saving to transfer the position of the support frame, force-increasing rods are provided at both ends of the cross beam, and the force-increasing rods are provided with force-increasing sleeves extending outward.

[0013] Further, the force-increasing rod includes a connecting block, an insertion rod is provided at the end of the connecting block, and the force-increasing sleeve can be inserted on the insertion rod.

[0014] Further, the connecting block is hinged to the cross beam. The connecting block can rotate to make the insertion rods on both sides move inward or relatively. Elastic elastic sleeves are provided at both ends of the force-increasing sleeve. A limiting column is provided on the side surface of the force-increasing sleeve. A telescopic pin is provided on the cross beam corresponding to the position of the limiting column. A wedge-shaped block is provided at the bottom of the telescopic pin. When the connecting block rotates outward 180 degrees, the limiting column crosses the telescopic pin and catches the limiting column.

[0015] The beneficial effects of the present invention are as follows: For the vibrating device for concrete pouring in aluminum formwork construction provided by this application, the operator only needs to place the support frame and insert the vibrating rod. The most laborious pulling out and holding actions are automatically realized by the equipment, which can effectively save the physical strength of the staff.

[0016] When moving the support frame, move it with the cross beam as the radius and another support frame as the center, ensuring that the distance between each vibration point is within the optimal range, ensuring that each vibration point has better vibration efficiency, while improving work efficiency and quality, reducing the number of vibrations.

[0017] The vibrating rod is always protected by the pipe sleeve, preventing the vibrating rod from contacting the steel bars and effectively isolating the vibration force of the vibrating rod. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0021] Embodiment 1, as Figures 1 - 4A 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 opening reserved for the aluminum formwork. The diameter of the placement plate 21 is large enough. When it is directly placed on the cement slurry, it will not be immersed in the cement slurry due to vibration. When it is placed on the steel cage, it will not fall from the net opening. The placement plate 21 is connected to the mounting platform 23 through the tripod 22. The middle 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, and the lifting plate 31 is fixedly connected to a hanger 32, and the hanger 32 is fixedly connected to a suspension rope 33. 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 hanger 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 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 and 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, which reduces the transmission of the vibration energy of the vibrating rod 1 to the lifting plate 31 and reduces the vibration of the lifting plate 31. The two support frames 2 are connected by a crossbeam 7 to form As a whole, the support frame 2 is movably connected to the beam 7 through the turntable 6, the beam 7 is hinged to the turntable 6, the beam 7 has multiple length specifications or the length can be adjusted to adapt to different types of vibrating rods 1, the rotating shaft of the beam 7 is stuck on the turntable 6, so as 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, the fixed pulley 34 is arranged above the turntable 6, the driving member 8 includes two capstans, both of which are connected to the motor transmission through a one-way bearing, and 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.

[0022] An elastic buffer pad 5 is provided at the bottom of the pipe clamp 4. 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 large rigidity. 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 prevents the pipe sleeve 36 from directly contacting the pipe clamp 4, thereby reducing the friction between the two and also providing buffering.

[0023] 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 sleeve 36 through the steel reinforcement cage. Since one motor drives two winches simultaneously, when one lifting frame 3 is lifted, the other will land. Therefore, it is necessary to make the lifting frame 3 on the other side land with a time delay. To ensure that both lifting frames 3 are in the lifting state and facilitate the insertion of the vibrating rod 1 into the sleeve 36, an elastic protrusion 35 is provided on the lifting rope 33. The protrusion 35 can be stuck in 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 sleeve 36 and the protrusion 35 is pulled out of the gap, the lifting frame 3 can land normally without interfering with the insertion of the vibrating rod 1 into the cement slurry.

[0024] 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. To ensure the synchronous landing of the vibrating rod 1 and the lifting frame 3, the inner wall of the 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 sleeve 36, the lifting frame 3 is prevented from separating from the vibrating rod 1.

[0025] 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, the countdown starts. After the countdown ends, the driving member 8 is started. The countdown is K seconds, where 20 < K < 30. When the fixed pulley 34 stops rotating, it 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 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.

[0026] During vibration, first place the support frame 2 in place, insert the vibrating rod 1 into the sleeve 36, pull down the lifting rope 33, and pull the protrusion 35 out of the gap between the fixed pulley 34 and the crossbeam 7. Control the insertion 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 around the vibrating support frame 2, and switch to the next vibration point. After reaching the set vibration time, the driving member 8 is started to evenly lift the lifting frame 3, and the vibrating rod 1 is evenly pulled out of the cement slurry. After the lifting frame 3 rises in place, pull out the vibrating rod 1, insert the vibrating rod 1 into another in-place lifting frame 3, and repeat the above process.

[0027] Please refer to Figures 4 - 6, in order to make it more labor-saving to move the position of the support frame 2, force-increasing rods 9 are provided at both ends of the cross beam 7. The force-increasing rods 9 extend outward. When lifting the support frame 2, the lever can be reused. The force-increasing rod 9 includes a connecting block 91 and a force-increasing sleeve 94. The force-increasing sleeves 94 on both sides share one force-increasing sleeve 94. The end of the connecting block 91 is provided with an insertion rod. When it is necessary to lift the support frame 2, the force-increasing sleeve 94 is sleeved on the connecting block 91. When not in use, the force-increasing sleeve 94 can be retracted to reduce the occupied space.

[0028] The connecting block 91 is hinged to the cross beam 7. When not in use, the connecting blocks 91 on both sides are rotated to make the insertion rods on both sides face inwards. Elastic elastic sleeves 95 are provided at both ends of the force-increasing sleeve 94. The elastic sleeves 95 center the force-increasing sleeve 94 so that the force-increasing sleeve 94 will not fall off.

[0029] A limit post 92 is provided on the side of the force-increasing sleeve 94. A telescopic pin 93 is provided at the position of the cross beam 7 corresponding to the limit post 92. A wedge block is provided at the bottom of the telescopic pin 93. When the connecting block 91 rotates 180 degrees, the limit post 92 passes over the telescopic pin 93, and the telescopic pin 93 catches the limit post 92 to limit the rotation of the connecting block 91, so that the force-increasing sleeve 94 can exert force. When it is necessary to retract the device, the telescopic pin 93 is toggled upwards, the connecting block 91 is rotated to make the insertion rods on both sides face inwards, and both ends of the force-increasing sleeve 94 are sleeved on the insertion rods.

Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
