DETAILED DESCRIPTION

[0028] The embodiments of the utility model are described in detail below in combination with the drawings, but the utility model can be implemented in various different ways limited and covered by the claims. Example 1:

[0029] Referring to Figures 1-5 An automatic obstacle-avoiding plug-in vibrator, comprising a vibrator body 1, an obstacle-avoiding rotary adjusting assembly 2 and an obstacle-avoiding monitoring unit, details as follows:

[0030] For details Figure 1 And Figure 2 The vibrator body 1 comprises a mounting bracket 1.1, a telescopic power source 1.2, a vibrating rod 1.3 and a mounting plate 1.9, the mounting bracket 1.1 is fixedly arranged below the mounting plate 1.9, the telescopic power source 1.2 is arranged on the mounting bracket 1.1, and the vibrating rod 1.3 is arranged on the telescopic power source 1.2, and the telescopic power source 1.2 drives the vibrating rod to stretch and retract and vibrate.

[0031] The obstacle-avoiding rotary adjusting assembly 2 comprises a support frame 2.1, a rotary power source 2.2 and a transmission connecting piece, the rotary power source 2.2 is arranged on the support frame 2.1, and the support frame 2.1 is fixedly connected with the mounting bracket 1.1; the transmission connecting piece is connected with the rotary power source 2.2, and the whole vibrator body 1 is driven to rotate by the action of the rotary power source to avoid obstacles;

[0032] The telescopic power source 1.2 and the rotary power source 2.2 are connected with the obstacle avoidance monitoring unit, which is used to detect the parameters (here, preferably the rotating speed of the telescopic power source 1.2, the current of the telescopic power source 1.2 and the current of the rotary power source 2.2) of the telescopic power source 1.2 and the rotary power source 2.2 and control the actions of the telescopic power source 1.2 and the rotary power source 2.2. In this embodiment, the telescopic power source 1.2 and the rotary power source 2.2 are preferably motors, specifically: the rotary power source 2.2 is a rotary motor, which can be a motor capable of forward and reverse rotation according to the requirements; the telescopic power source 1.2 is a telescopic motor, which rotates forward to realize the upward movement of the vibrating rod (i.e. the vibrating rod is extended) and rotates reversely to realize the downward movement of the vibrating rod (i.e. the vibrating rod is retracted).

[0033] In this embodiment, the transmission connecting piece preferably comprises a first gear 2.3 and a second gear 2.4 capable of meshing with each other, and the vibrator body 1 is rotatably arranged on the first gear 2.3, and the second gear 2.4 is arranged on the output end of the rotary power source 2.2, which will be described in detail in Figure 1 and Figure 3 . The first gear 2.3 comprises a ring body and teeth arranged on the ring body, and the hollow part of the ring body is used to accommodate the vibrator body 1. Here, preferably, a connecting ring 6 is riveted and welded on the lining trolley formwork 3, the first gear 2.3 is fixed on the connecting ring 6 by bolts, and the lower surface of the mounting plate 1.9 in the vibrator body 1 is lapped on the upper surface of the ring body in the first gear 2.3. Since the diameter of the mounting plate 1.9 is smaller than the outer ring diameter of the first gear 2.3 and larger than the inner diameter of the ring body in the first gear 2.3, the first gear 2.3 can limit the vibrator body 1 in the vertical direction to prevent it from moving downward. Since the mounting plate 1.9 and the first gear 2.3 are in a lapped relationship and are not fixedly connected, the mounting plate 1.9 and the first gear 2.3 can rotate relative to each other.

[0034] Further preferably, a dustproof component 4 is arranged at the contact part between the connecting ring 6 and the mounting plate 1.9, and the dustproof component is preferably a dustproof ring which prevents the entry of concrete between the mounting plate and the connecting ring.

[0035] Further preferably, the teeth of the first gear 2.3 are arranged on the outer circumference thereof, and the teeth of the second gear 2.4 are also arranged on the outer circumference thereof. In addition, an internal meshing structure can also be adopted, for example: the first gear comprises internal teeth, and the second gear can mesh with the internal teeth.

[0036] In the embodiment, the obstacle avoidance rotating adjusting assembly 2 further comprises a position limiter 2.5, which is arranged corresponding to the transmission connecting piece, and is used for limiting the limit position of the obstacle avoidance rotating adjusting assembly 2 during the rotating adjustment. Specifically, a limiting boss is arranged below the first gear 2.3, and when the rotating power source 2.2 and the limiting boss touch, it represents that the rotation is to the limit position.

[0037] In the embodiment, the mounting rack 1.1 is further provided with an observation device 5, which is used for monitoring whether the vibrating rod 1.3 is retracted in place. Details are shown in Figure 4 and Figure 5 The observation device 5 comprises a cover plate 5.1, a fastener 5.2, a window 5.3 and a protrusion 5.4. The cover plate 5.1 is a circular arc structure, which is spliced with the mounting rack 1.1 into a ring structure. The cover plate 5.1 is provided with the window 5.3, and the cover plate 5.1 is detachably arranged on the mounting rack 1.1 through the fastener 5.2. It is further preferred here that the fastener 5.2 comprises a hinge and a bayonet terminal, one end of the cover plate is hinged with the mounting rack, and the other end is clamped and fixed with the mounting rack through the bayonet terminal. When maintenance is needed, the maintenance operation can be realized by directly opening the bayonet terminal. The protrusion 5.4 is arranged on the inner wall of the cover plate 5.1 through an elastic piece (not shown) and is arranged corresponding to the window 5.3. The free end of the protrusion 5.4 can freely enter and exit the window 5.3. When the vibrating rod is retracted in place, the elastic piece is completely compressed, and the free end of the protrusion does not exceed the outer end face of the window towards the outer side of the vibrator body 1. If the vibrating rod is not retracted in place, the free end of the protrusion will exceed the outer end face of the window towards the outer side of the vibrator body 1. See Figure 4 In addition, it can also be designed that when the vibrating rod is retracted in place, the elastic piece is completely compressed, and the free end of the protrusion exceeds the outer end face of the window towards the outer side of the vibrator body 1. If the vibrating rod is not retracted in place, the free end of the protrusion will not exceed the outer end face of the window towards the outer side of the vibrator body 1. According to the actual needs, it is selected.

[0038] In the embodiment, the vibrator body 1 further comprises a lead screw 1.4, a shaft coupling 1.5, a vibrating rod connecting plate 1.6, a first fixed seat 1.7 and a second fixed seat 1.8. See Figure 1 and Figure 2, the screw rod 1.4 is a trapezoidal screw rod, and the lower end is connected with the output end of the telescopic power source 1.2 through a shaft coupling 1.5. The first fixed seat 1.7 and the second fixed seat 1.8 are arranged side by side on the mounting frame 1.1 along the telescopic direction of the vibrating rod (preferably welded and fixed here); both ends of the screw rod 1.4 are rotationally connected with the first fixed seat 1.7 and the second fixed seat 1.8; the vibrating rod 1.3 is arranged on the screw rod between the first fixed seat 1.7 and the second fixed seat 1.8 through a vibrating rod connecting plate 1.6, that is, the center axis of the vibrating rod and the center axis of the screw rod are offset and arranged in parallel; the vibrating rod connecting plate 1.6 is threadedly connected with the screw rod 1.4, when the screw rod 1.4 is rotated by the telescopic power source, the vibrating rod connecting plate 1.6 moves up and down along the screw rod 1.4, thereby driving the vibrating rod 1.3 to extend and retract. When the rotating power source 2.2 drives the second gear 2.4 to rotate, the second gear 2.4 meshes with the first gear 2.3 to drive the entire vibrator body 1 to rotate, thereby driving the vibrating rod 1.3 to swing to different vibrating points, achieving efficient vibration of the concrete.

[0039] The technical scheme of the embodiment is applied, specifically: the telescopic power source 1.2 acts to drive the screw rod 1.4 to rotate, so that the vibrating rod connecting plate 1.6 and the vibrating rod 1.3 on the screw rod 1.4 move up and down relative to the screw rod 1.4. The rotating power source 2.2 acts to drive the second gear 2.4 thereon to rotate, because the second gear 2.4 meshes with the first gear 2.3 and the first gear 2.3 is fixed, the rotating power source 2.2, the second gear 2.4, the support frame 2.1 and the entire vibrator body 1 connected with the support frame 2.1 rotate around the circumference of the first gear 2.3, thereby realizing swinging of the vibrating rod 1.3 in the vibrator body 1.

[0040] After the automatic obstacle-avoiding plug-in vibrator of the embodiment is assembled on the lining trolley formwork 3 to be constructed, vibration is performed, and the specific operation logic is shown in Figure 6, specifically: the telescopic power source is started, the telescopic power source controls the vibrating rod to extend upwards, the first layer of steel bars is 5 cm above the lining trolley formwork, if there are steel bars above the vibrating rod, when the vibrating rod hits the steel bars, the extension time is less than the set time, it can be judged that the vibrating rod hits the steel bars above, at this time, the vibrating rod needs to be retracted and rotated to avoid the steel bars, and the rotating power source is controlled to rotate for a set time, the rotating direction is consistent with the last vibrating rod rotating direction (if the vibrating rod hits the steel bars for the first time, the rotating direction is positive by default after retraction), and the above operation is repeated, if the rotating power source rotates to the limit stop, the current of the rotating power source becomes large, it is determined that the rotating power source rotates to the limit stop, the rotating power source is controlled to rotate in the opposite direction (the rotating direction is opposite to the last rotating direction of the rotating power source) for a set time, the operation is repeated until there are no steel bars above the vibrating rod; if there are no steel bars above the vibrating rod, the vibrating rod extension time is greater than the specified time, and the current becomes large, it is judged that the vibrating rod is extended to the position for vibrating. Whether the vibrating rod is retracted to the position can be determined manually through the above observation device. The specific vibrating method includes the following steps:

[0041] Step one, start the telescopic power source 1.2;

[0042] Step two, the obstacle avoidance monitoring unit obtains the current of the telescopic power source;

[0043] Step three, one-time judgment is made according to the judgment condition,

[0044] The judgment condition includes: the extension time T of the vibrating rod is greater than the set time T0; here, the extension time T of the vibrating rod is obtained in the following way: the start value of T is when the telescopic power source is started, and the end value of T is when the normal working current of the telescopic power source suddenly becomes large; when the vibrating rod encounters a steel bar or the vibrating rod is fully extended, the normal working current of the telescopic power source will suddenly become large; through testing and data collection, the extension time of the vibrating rod in the normal working state without encountering a steel bar is obtained, and the obtained time value is used as the set time T0;

[0045] The one-time judgment operation is as follows:

[0046] If the judgment condition is met, it is determined that there is no obstacle above the vibrating rod, and step six is entered; if the judgment condition is not met, it is determined that there is an obstacle above the vibrating rod, and the telescopic power source 1.2 controls the vibrating rod to retract;

[0047] Step four, start the rotating power source, control the rotating power source to rotate for a set time T1 (T1 is greater than 0), so that the rotating power source swings a distance D1 (the swinging distance is selected according to actual needs, generally related to the diameter of the steel bars used, and can avoid the steel bars); at the same time, the obstacle avoidance monitoring unit obtains the current of the rotating power source 2.2;

[0048] Step five, two-time judgment is made according to the judgment condition,

[0049] The determination condition includes: the current I1 of the rotating power source is greater than the set rotating current I0, wherein preferably: the rotating current of the rotating power source in the normal working state without encountering the limiting boss is obtained through testing and data collection, and the obtained current value is taken as the set time T0;

[0050] The secondary determination operation is as follows:

[0051] If the determination condition is not met, return to step one; if the determination condition is met, determine that the rotating power source has rotated to the limit position, control the rotating power source to reverse rotation, the reverse rotation time is T2 (T2 is greater than 0), the reverse rotation distance of the rotating power source is D2 (the reverse rotation distance is selected according to actual needs, which can realize avoiding the limit position), and the rotating power source is turned off; return to step one;

[0052] Step six, perform the vibrating operation.

[0053] When the automatic obstacle avoidance insert type vibrator is applied in this embodiment, the obstacle avoidance monitoring unit collects the current of the telescopic power source 1.2 and the current of the rotating power source 2.2 in real time, and determines whether there is a steel bar above the vibrating rod and whether the vibrator body 1 rotates to the limit position according to the unique determination strategy, and accurately realizes the adjustment control of the telescopic power source and the rotating power source, realizes automatic obstacle avoidance, and greatly improves the construction efficiency. Embodiment 2:

[0054] The difference between this embodiment and embodiment 1 is:

[0055] The structure of the transmission connecting piece is different: for example Figure 7 , the rotating power source 2.2 is fixedly arranged on the lining trolley formwork 3, the transmission connecting piece includes a first pulley 2.6, a second pulley 2.7 and a transmission belt 2.8, the first pulley 2.6 is fixedly arranged on the vibrator body (preferably the first pulley is fixedly arranged on the mounting rack 1.1), the second pulley 2.7 is fixedly arranged on the output end of the rotating power source 2.2, and the transmission belt 2.8 is simultaneously sleeved on the first pulley 2.6 and the second pulley 2.7, so as to ensure that the first pulley rotates synchronously with the second pulley, thereby driving the vibrating rod 1.3 to swing by a certain angle. The installation position of the limiter 2.5 is different: for example Figure 7 , the limiter 2.5 includes a first limiting block arranged on the transmission belt and a second limiting block arranged on the mounting rack, and when the first limiting block and the second limiting block abut, it indicates that the rotation has reached the limit position.

[0056] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
