The steel frame is sunk by vibration to produce the small prefabricated components. However, it is difficult to control the amount of sinking of the steel frame by direct vibration. As a result, the sinking amount and the sinking angle of the steel frame cannot be controlled after vibration, which directly affects the quality of the small prefabricated components.

[0039] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0040] The present invention includes two parts: execution parameter calculation and actuator (concrete vibrating equipment 4) driving. Among them, the execution parameter calculation needs to be calculated separately according to different small prefabricated components, and the actuator (concrete vibrating equipment 4) is also adjusted accordingly with different small prefabricated components. The advantage of doing so is that it can better achieve the effect of accurately controlling the construction quality of small prefabricated components.

[0041] like Figure 1 As shown, the actuator (concrete vibrating equipment 4) is installed on one side of the conveyor belt 3, which includes a lifting frame 41 and a matrix vibrator 42 connected to the sliding lifting component 412 of the lifting frame 41. The matrix vibrator 42 is suitable for vibrating the concrete in the small prefabricated component template 1.

[0042] Among them, the lifting frame 41 includes a sliding rail frame 411 set on the ground, a sliding lifting component 412 is slidingly connected to the sliding rail frame 411, and a telescopic cylinder 413 is connected between the sliding rail frame 411 and the sliding lifting component 412 to drive the sliding lifting component 412 to rise and fall on the sliding rail frame 411.

[0043] The telescopic cylinder 413 may be a hydraulic cylinder or an electric push rod. Driven by the telescopic cylinder 413 , the sliding lifting component 412 may move on the track of the slide rail stand 411 , thereby driving the matrix vibrator 42 to perform vertical lifting.

[0044] like Figures 2-3As shown, the matrix vibrator 42 includes a mounting frame 421 connected to the slide, and the mounting frame 421 has a plurality of mounting holes evenly distributed in a matrix. A vibrating rod 422 is detachably installed in each mounting hole. Each vibrating rod 422 operates independently according to the calculated vibration power and vibration time to vibrate the concrete in the small prefabricated component template 1 and sink the steel frame 2 to a preset position.

[0045] In the above-mentioned settlement process, in addition to controlling the settlement depth, the settlement angle is also included. For example, when it settles to the preset position, its angle is in a horizontal state. For another example, when it settles to the preset position, its angle is deflected by 15 to 20 degrees relative to the bottom plate of the small prefabricated component template 1.

[0046] Among them, the vibrating rod 422 includes a driver 422a and a vibrating head 422c, which are respectively arranged on the upper and lower sides of the mounting frame 421 with a mounting hole plate. The driver 422a is connected to the vibrating head 422c through a power transmission hose 422b, and the output shaft of the driver 422a is connected to the power input end of the vibrating head 422c through the soft shaft in the power transmission hose 422b to drive its operation.

[0047] The above-mentioned driver 422a is detachably connected to the mounting frame 421 having a mounting hole plate surface by means of threaded connection, detachable snap connection, etc., wherein the driver 422a, the power transmission hose 422b and the vibrating head 422c all adopt existing technologies. The driver 422a adopts a motor, and the solution of connecting it to the vibrating head 422c through the power transmission hose 422b also adopts existing technologies. Its structure and working principle will not be repeated here.

[0048] The difference between the present invention and the concrete vibration structure in the prior art is that: a spring 422d is sleeved on the surface of the power transmission hose 422b, and the two ends of the spring 422d respectively conflict with the mounting hole plate surface of the mounting frame 421 and the vibrating head 422c. The advantage of this arrangement is that the vibrating head 422c can be supported to avoid excessive swinging during operation and to limit its position.

[0049] Among them, the specific structure of the spring 422d and the vibrating head 422c is as follows: a detachable retaining ring is provided on the vibrating head 422c, such as a threaded retaining ring. After the spring 422d is put on the vibrating rod 422, the retaining ring is installed to form a structure in which the two ends of the spring 422d respectively conflict with the mounting hole plate surface of the mounting frame 421 and the vibrating head 422c.

[0050] like Figure 4As shown, the controller 5 is respectively connected to the signal input / output terminals of the telescopic cylinder 413 and the driver 422a for controlling the operation of the telescopic cylinder 413 and the driver 422a, wherein the controller 5 is provided with a vibration analysis module 51, a vibration point allocation module 52 and a position analysis module 53;

[0051] The vibration analysis module 51 is adapted to construct a vibration settlement analysis model according to the concrete parameters and the steel frame 2 parameters.

[0052] The vibration point allocation module 52 is adapted to identify the vibration points using the above analysis model; and obtain vibration parameters, including vibration power and vibration time.

[0053] The process of obtaining the vibration point includes the following steps:

[0054] Construct a model of the concrete vibrating equipment 4;

[0055] According to the parameters of the steel frame 2, the positions of the vibrating rods 422 involved in the operation are identified, and a set of the positions of the vibrating rods 422 is obtained;

[0056] The vibration settlement analysis model is used to simulate the vibrating rod 422 point in the vibrating rod 422 point set, and the deletable points are removed;

[0057] Output vibration points.

[0058] The process of obtaining vibration parameters includes the following steps:

[0059] Set the initial vibration power and initial vibration time;

[0060] According to the preset settlement position of the steel frame 2, a reverse simulation is performed using the vibration settlement analysis model to adjust the initial vibration power and initial vibration time respectively;

[0061] Forward simulation is performed based on the obtained vibration power and vibration time. If the steel frame 2 sinks to the preset position, the vibration parameters are output. If the steel frame 2 fails to sink to the preset position, the simulation is readjusted and performed until the steel frame 2 sinks to the preset position.

[0062] The position analysis module 53 is adapted to calculate the position of the steel frame 2 according to the vibration parameters during the vibration process of the concrete vibrating device 4 based on the above analysis model.

[0063] The position analysis module 53 is further configured to output a prompt message after detecting that the steel frame 2 has settled to a preset position.

[0064] During the construction of small prefabricated components:

[0065] 1. According to the concrete parameters and the parameters of the steel frame 2, the vibration points, vibration power and vibration time are obtained, and other unnecessary vibrating rods 422 are removed according to the vibration points.

[0066] 2. After the steel frame 2 is placed into the small prefabricated component template 1, the controller controls the telescopic cylinder 413 to drive the matrix vibrator 42 to extend into the small prefabricated component template 1.

[0067] 3. The vibrating rods 422 at the vibration points operate independently according to the calculated vibration power and vibration time. Under the vibration action, the steel frame 2 sinks into the concrete injected into the small prefabricated component template 1.

[0068] The vibration power and vibration time of the vibrating rod 422 at each of the above-mentioned vibration points are set to be the same or different. The vibrating rod 422 at each vibration point operates independently according to the allocated vibration power and vibration time, thereby driving the steel frame to settle the concrete in the small prefabricated component template 1, thereby achieving the effect of controlling the settlement position of the steel frame 2.

[0069] 4. After sinking to the preset position, the controller controls the telescopic cylinder 413 to drive the matrix vibrator 42 to be withdrawn from the interior of the small prefabricated component template 1.

[0070] The present invention can obtain corresponding vibration points and vibration parameters according to the concrete parameters and the parameters of the steel frame 2. During the vibration process, different vibration powers and vibration times are used to control the sinking of the steel frame 2 so that it can sink to a preset position, thereby achieving the effect of controlling the quality of small prefabricated components.

[0071] It should be noted that the specific models and specifications of the telescopic cylinder 413, the driver 422a, and the controller 5 need to be selected and determined according to the actual specifications of the device.
