TECHNICAL FIELD

[0002] The concrete vibrating link is a crucial process in concrete construction, which can eliminate the air bubbles in the concrete, make the cement paste fully wrap the steel bars and fill the gap between the steel bars and the concrete, ensure the full contact of the concrete with the steel bars and the formwork, improve the compactness of the concrete product, and achieve the improvement of the compressive strength and the flexural strength of the concrete. Therefore, in the concrete construction, the operation must be strictly carried out according to the specification requirements.

[0003] The direction control of the concrete vibrating rod is a core technical link to ensure the quality of concrete pouring.

The vibrating rod vibrating path and direction control can overcome the construction space limitation, and realize the accurate vibration of the concrete through the direction angle adjustment of the vibrating rod.

Obviously, the described embodiments are some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0054] The embodiments of the present application will be described below in detail with reference to the drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0055] The existing concrete vibrating device cannot flexibly control the direction angle, which leads to the problem that it is difficult to overcome the construction space limitation to realize the accurate concrete vibration full-area coverage, and further cannot ensure the concrete compactness around the steel dense area, the formwork corner and the embedded part.

[0056] Therefore, the present application provides a concrete vibrating device, which comprises a vibrating head 100, a guide mechanism 200 and a driving mechanism 300. The guide mechanism 200 comprises a first connecting piece 210, a second connecting piece 220, a third connecting piece 230, a first driving line 240 and a second driving line 250. One end of the first connecting piece 210 is connected with the vibrating head 100, and the other end is hinged to the second connecting piece 220. One end of the second connecting piece 220 away from the first connecting piece 210 is hinged to the third connecting piece 230. One end of each of the two first driving lines 240 is connected with the first connecting piece 210, and the other end is connected with the driving mechanism 300, for driving the first connecting piece 210 to swing in a first plane. One end of each of the two second driving lines 250 is connected with the second connecting piece 220, and the other end is connected with the driving mechanism 300, for driving the second connecting piece 220 to swing in a second plane. The first plane is perpendicular to the second plane.

[0057] The three connecting pieces of the concrete vibrating device provided by the present application are hinged in sequence, and the two hinged swing planes are perpendicular to each other, so that the angle of the vibrating head 100 can be flexibly adjusted, the direction angle of the vibrating head is flexibly controlled, the construction space limitation is avoided to realize the accurate concrete vibration full-area coverage, and the concrete compactness around the steel dense area, the formwork corner and the embedded part is ensured. At the same time, the swinging of the first connecting piece 210 and the second connecting piece 220 is driven by the driving line, the vibration of the vibrating head 100 is buffered by the driving line, which will not affect the related driving mechanism 300, and the service life of the device is not obviously reduced due to the vibration.

[0058] The following will be described in detail Figures 1-11The structure and shape of the concrete vibrating device provided in the embodiment are described in detail.

[0059] In some optional embodiments, the driving mechanism 300 comprises a first driving assembly and a second driving assembly; the first driving assembly comprises two driving units, which are respectively connected with two ends of the two first driving lines 240 away from the first connecting piece 210, for driving the first driving lines 240 to move, and further driving the first connecting piece 210 to swing in the first plane. That is, when the first connecting piece 210 is driven to swing, one driving unit can pull one first driving line 240, and the two first driving lines 240 are uniformly distributed around the axis of the first connecting piece 210.

[0060] The second driving assembly comprises two driving units, which are respectively connected with two ends of the two second driving lines 250 away from the second connecting piece 220, for driving the second driving lines 250 to move, and further driving the second connecting piece 220 to swing in the second plane. The working principle is the same as that of the first driving assembly, and will not be repeated here. The two second driving lines 346 are uniformly distributed around the axis of the second connecting piece 220.

[0061] In some optional embodiments, the driving unit comprises a driving shell 310; the driving shell 310 of the first driving assembly is connected with one end of the first driving line 240 away from the first connecting piece 210, as shown in Figure 6 The driving shell 310 of the second driving assembly is connected with one end of the second driving line 250 away from the second connecting piece 220. The driving line is driven to move by the driving shell 310, and further drives the connected connecting piece to swing.

[0062] In some optional embodiments, the driving unit further comprises an execution slider 320, which is slidingly installed in the driving shell 310 and is configured to abut against the driving shell 310 and drive the driving shell 310 to move. Specifically, as shown in Figure 6 、 Figure 7 The driving shell 310 is provided with an inner cavity, and the execution slider 320 is slidingly installed in the inner cavity. In order to ensure the linear motion of the execution slider 320, the inner cavity of the driving shell 310 is provided with a first guide baffle 312, and the two first guide baffles 312 are arranged on both sides of the sliding direction of the execution slider 320, as shown in Figure 7

[0063] ​In some optional embodiments, the first driving assembly further comprises a first unlocking line 31, one end of which is connected with the execution slider 320, and the other end sequentially passes through the third connecting piece 230, the second connecting piece 220, the first connecting piece 210, then makes a half turn around the outer circle of the first connecting piece 210, returns to the first connecting piece 210, and sequentially passes through the first connecting piece 210, the second connecting piece 220 and the third connecting piece 230, and then is connected with the execution slider 320 of the other driving unit, as shown in Figure 1 , Figure 3 .

[0064] The second driving assembly further comprises a second unlocking line 32, one end of which is connected with the execution slider 320, and the other end sequentially passes through the third connecting piece 230 and the second connecting piece 220, then makes a half turn around the outer circle of the second connecting piece 220, returns to the second connecting piece 220, and sequentially passes through the second connecting piece 220 and the third connecting piece 230, and then is connected with the execution slider 320 of the other driving unit. That is, in one driving assembly, the two ends of the unlocking line are respectively connected with the execution sliders 320 of two driving units, and the unlocking line makes the two execution sliders 320 connected therewith move reversely synchronously through the above threading mode.

[0065] Specifically, as shown in Figure 2 , the outer walls of the first connecting piece 210, the second connecting piece 220 and the third connecting piece 230 are respectively provided with a threading plate 211, and the threading plate 211 is provided with two threading holes for the unlocking line and the driving line to pass through to guide the movement of the unlocking line and the driving line. Among them, the outer walls of the first connecting piece 210 and the second connecting piece 220 are further provided with a lead slot extending along the circumference, as shown in Figure 1 , Figure 3 , the lead slot extends for a half circle, and is used for the unlocking line to pass through to make the unlocking line return, so that the two edges formed by the return of the unlocking line are uniformly distributed around the axis of the connecting piece.

[0066] In some optional embodiments, the driving unit further comprises a sliding rail 330 and a locking structure 340, the driving housing 310 is slidingly installed on the sliding rail 330; the locking structure 340 comprises a latch block 341; the locking structure 340 has an unlocked state and a locked state; in the locked state, the latch block 341 is simultaneously inserted into the driving housing 310 and the sliding rail 330; in the unlocked state, the latch block 341 is withdrawn from the sliding rail 330. As shown in Figure 4 , Figure 9 , the sliding rail 330 has the same structure as the C-shaped steel, and is used for guiding the movement of the driving housing 310.

[0067] In some optional embodiments, the locking structure 340 further comprises a first spring 342, which is configured to apply a pushing force to the plug block 341 to make the plug block 341 have a tendency to move towards the sliding rail 330 and be inserted into the sliding rail 330.

[0068] Further, the plug block 341 is provided with a slope, in the locked state, when the driving shell 310 moves in the direction away from the vibrating head 100, the plug block 341 is driven out of the sliding rail 330 under the action of the slope and has a tendency to move to re-insert into the sliding rail 330.

[0069] Specifically, as shown in Figure 6 , Figure 9 , the side wall of the driving shell 310 is provided with a through groove 311, and the inner wall of the sliding rail 330 is provided with a plurality of insertion grooves 331 arranged along the length direction of the sliding rail 330. In the locked state, the plug block 341 is simultaneously inserted into the through groove 311 and the insertion groove 331. At this time, due to the slope of the plug block 341, if the driving shell 310 moves in the direction of pulling the driving wire, the plug block 341 will be driven out of the insertion groove 331 under the action of the component force formed by the slope, but the driving shell 310 will be prevented from moving in the reverse direction by the plug block 341, thereby ensuring that the driving shell 310 will not be pulled to move by the pulling force of the driving wire, and the angle of the first connecting piece 210 and the second connecting piece 220 is stable.

[0070] It should be noted that the slope of the plug block 341 can be an arc surface, and after the plug block 341 is inserted into the insertion groove 331, the slope thereof abuts against the edge of the entrance of the insertion groove 331, that is, the slope segment is not completely inserted into the insertion groove 331.

[0071] In some optional embodiments, the locking structure 340 further comprises a first wedge block 343 and a swing lever 344, as shown in Figure 8 . Specifically, one end of the first spring 342 is connected with the plug block 341, and the other end is connected with the first wedge block 343. The moving direction of the driving shell 310 is the first direction, the first wedge block 343 and the plug block 341 are slidingly installed on the driving shell 310 and are configured to be able to slide along the second direction, and the first direction is perpendicular to the second direction. The swing lever 344 is provided with a sliding groove extending along the length direction thereof, and the first wedge block 343 is provided with a sliding shaft inserted into and sliding along the sliding groove; the swing lever 344 is hinged to the driving shell 310 and is configured to be able to swing around the hinge point to drive the first wedge block 343, the first spring 342 and the plug block 341 to move towards or away from the sliding rail 330 along the second direction.

[0072] In some optional embodiments, the locking structure 340 further comprises a second wedge block 345 and a second spring 346; the second wedge block 345 is slidingly installed on the driving shell 310 and is configured to be able to slide in the second direction; one end of the second spring 346 is connected with the driving shell 310 and the other end is connected with the second wedge block 345, which is configured to apply a pushing force to the second wedge block 345 to move the second wedge block 345 towards the execution sliding block 320.

[0073] In the embodiment, the midpoint of the swing rod 344 is hingedly connected with the driving shell 310, and both ends of the swing rod 344 are respectively provided with sliding grooves extending along the length direction of the swing rod 344, and the second wedge block 345 and the first wedge block 343 are both provided with sliding shafts which are inserted into and slide along the sliding grooves.

[0074] The first wedge block 343 is arranged at the end of the second wedge block 345 away from the vibrating head 100; the second wedge block 345 and the first wedge block 343 are respectively matched with the execution sliding block 320 through inclined surfaces, and the execution sliding block 320 moves in the first direction to push the second wedge block 345 and the first wedge block 343 to move in the second direction through the inclined surfaces.

[0075] Correspondingly, the inner cavity of the driving shell 310 is provided with second guide baffles 313 extending in the second direction, and the two second guide baffles 313 form a guide channel to ensure that the second wedge block 345, the first wedge block 343 and the plug block 341 only reciprocate in the second direction.

[0076] In some optional embodiments, the driving unit further comprises a linear driving member 350, which is connected with the execution sliding block 320 and used to drive the execution sliding block 320 to move linearly. Figure 4 、 Figure 6 As shown in FIG. 8, the driving unit further comprises a connecting rod 360, one end of which is connected with the execution sliding block 320 and the other end of which is connected with the linear driving member 350, which is used to increase the distance between the linear driving member 350 and the execution sliding block 320 to ensure that a large enough angle adjustment can be achieved.

[0077] In the embodiment, the linear driving member 350 is a step linear motor.

[0078] In some optional embodiments, the driving mechanism 300 further comprises a driving box 33, and the driving unit is installed on the driving box 33. Specifically, the driving box 33 is a rectangular box body, and four driving units are respectively installed on four inner walls of the driving box 33, as shown in FIG. 9. Figure 4 、 Figure 5 That is, the driving box 33 is provided with a sliding rail 330 and a linear driving member 350. One end of the third connecting member 230 away from the second connecting member 220 is connected with the driving box 33. The remaining two side walls of the driving box 33 are provided with holes for passing through driving lines, unlocking lines, signal power lines and the like.

[0079] In some optional embodiments, the vibratory head 100 incorporates a posture sensor, which is wrapped with a cushioning material to reduce the impact of vibration; the cushioning material may be rubber. Specifically, the posture sensor may be configured as a combination of an accelerometer and a gyroscope to determine the orientation of the vibratory head 100.

[0080] In this embodiment, both the drive line and the unlocking line are made of steel wire rope.

[0081] In an optional embodiment, the concrete vibrating device further includes a central processing unit, which is connected to the posture sensor and controls the movement of the linear drive 350 through the data from the posture sensor.

[0082] In this embodiment, the concrete vibration device also includes a flexible hose, and the vibration head 100, guide mechanism 200, and drive mechanism 300 are all wrapped in the flexible hose to form a seal. The first connector 210, the second connector 220, and the third connector 230 are all hollow structures for the passage of related cables and pipes, thereby reducing the size of the device and protecting the cables and pipes.

[0083] The concrete vibrating device provided in this embodiment uses sensors to perceive the working environment of the vibrating head 100 in the concrete in real time. Based on the feedback information, it precisely controls the motor movement to drive the guide mechanism 200 to achieve dynamic steering. Compared with traditional concrete vibrating devices, it greatly improves the bending flexibility of the vibrating head 100 and can precisely control the direction of the vibrating head 100. The guiding mechanism significantly reduces honeycomb, voids, and even segregation problems in concrete products, extending the service life of building structures and unifying construction efficiency improvement with equipment reliability assurance.

[0084] like Figure 10 As shown, the dashed line represents the position of the first connector 210 after rotation. Before rotation, the length of the drive line between the first connector 210 and the second connector 220 is L1, the angle between the hypotenuses of the first connector 210 and the second connector 220 is α, and the straight line length of the hypotenuses of the first connector 210 and the second connector 220 is d. When the required rotation angle is θ, the drive line on the right side becomes shorter. According to the law of cosines, the length of the drive line between the first connector 210 and the second connector 220 after shortening is L2 = That is, when the first connector 210 and the second connector 220 change from a collinear state to a swing angle θ, the length of the first drive line 240 needs to be pulled. .

[0085] The working process of the concrete vibrating device provided by the embodiment is as follows, taking the swinging of the first connecting member 210 driven by the first driving assembly as an example: taking the two driving units of the first driving assembly as the left driving unit and the right driving unit, and taking the two first driving lines 240 as the left driving line and the right driving line, as shown in Figure 11 , the left and right are distinguished by illustration.

[0086] When the first connecting member 210 needs to swing to the left, the linear driving member 350 of the left driving unit drives the execution slide block 320 to move away from the third connecting member 230, that is, the execution slide block 320 moves downward as shown in Figure 7 ; at the same time, the linear driving member 350 of the right driving unit synchronously drives the execution slide block 320 to move towards the third connecting member 230, that is, the execution slide block 320 moves upward as shown in Figure 7 . It should be noted that the movement of the execution slide block 320 of the right driving unit towards the third connecting member 230 can be driven by the first unlocking line 31, which synchronously drives the execution slide block 320 of the left driving unit and the execution slide block 320 of the right driving unit to move reversely under the action of the first unlocking line 31, without the need for the linear driving member 350 to actively drive. Therefore, during the swinging, the two linear driving members 350 move reversely synchronously to avoid the position deviation of the driving shell 310 caused by the driving line, so that the latch block 341 cannot be aligned with the slot 331 of the sliding rail 330; the synchronous reverse movement of the two execution slide blocks 320 can also be maintained by the unlocking line.

[0087] When the execution slide block 320 of the left driving unit moves downward and abuts against the lower wall of the driving shell 310, the execution slide block 320 of the right driving unit moves upward and abuts against the upper wall of the driving shell 310, at this time, the locking structure 340 of the left driving unit is in the locked state, and the locking structure 340 of the right driving unit is in the unlocked state, as shown in Figure 11 .

[0088] Specifically, referring to Figure 7 , Figure 8 , Figure 11 , in the left driving unit, when the execution slide block 320 moves away from the third connecting member 230, the inclined surface of the execution slide block 320 contacts the inclined surface of the first wedge block 343, thereby pushing the first wedge block 343 away from the execution slide block 320 and compressing the first spring 342, and then the second spring 342 pushes the latch block 341 to insert into the sliding rail 330 to enter the locked state, in this process, the first wedge block 343 drives the swing lever 344 to swing to make the swing lever 344 drive the second wedge block 345 to move close to the execution slide block 320, and the second spring 346 can assist the second wedge block 345 to move close to the execution slide block 320. The locking is completed when the execution slide block 320 abuts against the driving shell 310. It should be noted that the locked state is one-way locking, which does not affect the pulling of the left driving line by the linear driving member 350.

[0089] That is, the linear drive 350 of the left drive unit drives the execution slider 320 to move downward, and the locking structure 340 enters the locked state. When the execution slider 320 abuts against the lower wall of the drive housing 310, the drive housing 310 continues to move with the execution slider 320 and pulls the left drive wire to swing the first connecting piece 210 to the left. At this time, with the movement of the drive housing 310, the latch block 341 can be pulled out of the slot 331 of the sliding track 330 under the action of the inclined surface, and then inserted into the next slot 331 under the action of the first spring 342, and the action is repeated until the first connecting piece 210 is swung to the position, and the linear drive 350 stops working. At this time, the latch block 341 is inserted into the slot 331 to keep the left drive wire locked.

[0090] In the right drive unit, when the execution slider 320 moves upward, the locking structure 340 is unlocked. Specifically, the inclined surface on the upper part of the execution slider 320 contacts the inclined surface of the second wedge block 345, thereby pushing the second wedge block 345 away from the execution slider 320 and compressing the second spring 346. In this process, under the action of the lever, the second wedge block 345 drives the swing lever 344 to swing to make the swing lever 344 drive the first wedge block 343, the first spring 342 and the latch block 341 close to the execution slider 320, and then the latch block 341 is pulled out of the sliding track 330. When the execution slider 320 abuts against the drive housing 310, the unlocking is completed, and the right drive wire cannot move, thereby ensuring that the first connecting piece 210 can swing to the left.

[0091] In order to avoid continuous stress of the linear drive 350 from causing damage, and to keep both drive housings 310 fixed by the latch block 341, after the first connecting piece 210 is swung to the position, the two linear drives 350 drive the two execution sliders 320 to move reversely for a distance, so that the execution slider 320 is separated from the drive housing 310. At this time, the execution slider 320 is located at the middle position of the drive housing 310 and does not contact the second wedge block 345 and the first wedge block 343, as shown in FIG. 6. Figure 7 At this time, the locking structure 340 of the left drive unit keeps the locked state under the action of the second spring 346, and the locking structure 340 of the right drive unit acts under the action of the second spring 346 and enters the locked state, that is, the second spring 346 pushes the second wedge block 345 and makes the swing lever 344 swing. At this time, the drive housings 310 connected with the two first drive wires 240 are fixed to the sliding track 330 by the latch block 341, so that the angle of the first connecting piece 210 is stable.

[0092] It should be noted that when adjusting the angle of the vibrating head, the swing adjustment of the second connecting piece 220 is completed first, and then the adjustment of the first connecting piece 210 is completed. The reason is that if the order is reversed, that is, the first connecting piece 210 is adjusted first, and then the second connecting piece 220 is adjusted, it will cause the angle of the first connecting piece 210 to change and the connection to be unstable; adjusting the angle of the second connecting piece 220 first will not cause this problem, because the first connecting piece 210 is adjusted on the basis of the second connecting piece 220.

[0093] The concrete vibrating device provided by the embodiment can control the motor to adjust the direction according to the deviation between the detected real-time direction and the ideal direction when working in concrete, compared with the traditional concrete vibrating device, the flexibility and construction efficiency of the concrete vibrating device are improved, and the hidden defect of the concrete product is reduced.

[0094] The driving unit of the concrete vibrating device provided by the embodiment can drive the locking structure 340 to switch states and move the driving wire with the linear driving piece 350, so that the direction and angle can be adjusted directly in the state of being inserted into the concrete without being pulled out of the concrete. The driving wire connection mode concentrates the vibration on the wire, and the vibration energy gradually decreases with the driving wire, avoiding damage to the driving unit and related parts caused by vibration. That is, the elastic connection of the driving wire buffers the vibration and instantaneous impact load, avoiding causing equipment fatigue damage. It should be noted that the elasticity of the driving wire is its own characteristic, and the material selected has sufficient rigidity to avoid excessive length change, thereby ensuring the stability of the angle.
