[0002] Precast concrete components are concrete products manufactured in factories using standardized and mechanized methods. They are widely used in construction, transportation, water conservancy, and other fields. Precast concrete components have advantages such as stable and reliable quality, high construction efficiency, low cost, energy saving and environmental protection, and low safety risks.

[0003] Currently, in the production process of precast concrete components, after concrete is poured into the mold, the vibrator installed in the mold needs to be connected to the drive source to vibrate the concrete in the mold. However, the drive source is currently manually plugged and unplugged to connect the vibrator, which results in low production efficiency. Moreover, the vibration time is entirely controlled manually, making it difficult to guarantee the construction quality. In addition, the construction environment is harsh, the labor intensity is high, and it may also cause injury to the construction workers.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide a pneumatic vibrator connection device to at least solve the above-mentioned problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A pneumatic vibrator air circuit connection device, the connection device comprising: The base is slidably mounted on the track; A male connector is mounted on a base and is connected to an air source via a telescopic pipe. A telescopic mechanism, which is connected to the male connector, is used to drive the male connector to perform telescopic movement; A positioning component for monitoring the alignment of the male connector with the female connector on the vibrator in the mold; The controller, telescopic mechanism, and positioning component are all connected to the controller signal. When the positioning component detects that the male connector and female connector are aligned, it transmits the positioning signal to the controller. Then the controller controls the telescopic mechanism to extend, driving the male connector and female connector to mate.

[0010] In the pneumatic vibrator air circuit connection device described above, preferably, a solenoid valve is provided on the telescopic tube, and the solenoid valve is used to control the opening and closing of the telescopic tube.

[0011] In the pneumatic vibrator air circuit connection device described above, preferably, the solenoid valve is connected to the controller via a time relay, and the time relay is used to control the opening duration of the solenoid valve.

[0012] In the pneumatic vibrator air circuit connection device described above, preferably, the interface portion of the male connector has a conical structure.

[0013] Preferably, in the pneumatic vibrator air circuit connection device described above, a limiting block is provided on each side of the base movement direction, and the limiting block is used to limit the range of base movement along the track.

[0014] In the pneumatic vibrator air circuit connection device described above, preferably, the base is provided with multiple guide rods, and a floating plate is guided to move along the vertical direction on the guide rods. An upper spring and a lower spring are sleeved on the guide rods. The upper spring is located above the floating plate, and the lower spring is located below the floating plate.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0024] According to specific embodiments of this utility model, such as Figure 1-3 As shown, this utility model provides an air circuit connection device for a pneumatic vibrator, the connection device comprising: Base 1 is slidably mounted on the track.

[0025] Male connector 3 is installed on base 1 and is connected to the air source through telescopic pipe 4.

[0026] The telescopic mechanism is connected to the male connector 3 and is used to drive the male connector 3 to perform telescopic movement.

[0027] The positioning component is used to monitor the alignment of the male connector 3 with the female connector 9 on the vibrator in the mold 8.

[0028] The controller, telescopic mechanism, and positioning component are all connected to the controller signal. When the positioning component detects that the male connector 3 and the female connector 9 are aligned, it transmits the positioning signal to the controller. Then the controller controls the telescopic mechanism to extend, driving the male connector 3 and the female connector 9 to dock.

[0029] When the connecting device is in use, a vibrator is installed on the mold 8. The mold 8 moves along its track. When the positioning component detects that the female connector 9 of the vibrator in the mold 8 is aligned with the male connector 3 on the base 1, the positioning component sends a signal to the controller. After receiving the corresponding signal, the controller sends a signal to the telescopic mechanism. The telescopic mechanism extends to drive the male connector 3 to connect with the female connector 9. At this time, the air source supplies air to the vibrator through the telescopic pipe 4. After the vibrator has vibrated for the set time, the telescopic mechanism drives the male connector 3 to retract, completing the concrete vibration operation.

[0030] It achieves fully automated docking and disconnection of the vibrator and the air source, which greatly improves construction efficiency and reduces the labor intensity of construction workers compared to manual insertion and removal, and can avoid injury to construction workers.

[0031] The positioning component includes an infrared transmitter 11 and an infrared receiver 12; the infrared transmitter 11 is mounted on the mold 8 and is used to emit infrared signals; the infrared receiver 12 is mounted on the base 1 and is used to receive infrared signals and convert them into electrical signals to be transmitted to the controller.

[0032] In one embodiment of this application, when the mold 8 moves to the point where the infrared transmitter 11 and the infrared receiver 12 are aligned, the mold 8 stops moving. At this time, the male connector 3 and the female connector 9 are aligned, and the infrared receiver 12 converts the received infrared signal into an electrical signal and transmits it to the controller.

[0033] In other embodiments, the positioning component may also be a positioning structure such as an ultrasonic sensor or a visual positioning sensor.

[0034] A pressure sensor 10 is installed at the bottom of the mold 8. The pressure sensor 10 is used to monitor the quality of concrete falling into the mold 8.

[0035] In one embodiment of this application, the pressure sensor 10 monitors the mass of concrete falling into the mold 8 in real time. Concrete is quantitatively added to the mold 8 through a material feeding device. When the mass of concrete in the mold 8 reaches the set value, the pressure sensor 10 transmits its monitoring signal outward.

[0036] The pressure sensor 10 is connected to a wireless signal transmitter, and a wireless signal receiver is also connected to the controller.

[0037] In one embodiment of this application, when the pressure sensor 10 detects that the concrete mass in the mold 8 has reached the set value, the pressure sensor 10 converts the detected pressure signal into an electrical signal and transmits it to the wireless signal transmitter. The wireless signal transmitter converts the electrical signal into a wireless transmission signal and transmits it outward. After receiving the wireless transmission signal, the wireless signal receiver converts it into an electrical signal and then transmits it to the controller. At this time, the controller can perform the next control action according to the specific signal.

[0038] A solenoid valve 13 is provided on the telescopic pipe 4, which is used to control the opening and closing of the telescopic pipe 4. In one embodiment of this application, when the solenoid valve 13 is open, the air source supplies air through the telescopic pipe 4, and when the solenoid valve 13 is closed, the air supply to the telescopic pipe 4 is interrupted.

[0039] Solenoid valve 13 is connected to the controller via time relay 14, which is used to control the opening duration of solenoid valve 13.

[0040] In one embodiment of this application, when the controller receives an electrical signal transmitted by the wireless signal receiver, it indicates that the concrete in the mold 8 has been poured and the next vibration operation can be carried out. The controller sends a start signal to the time relay 14, and the time relay 14 controls the solenoid valve 13 to open. At this time, the air source supplies air to the vibrator through the telescopic pipe 4, and the vibrator starts the vibration operation. After the time relay 14 has run for the set time, the time relay 14 cuts off the power supply to the solenoid valve 13, the solenoid valve 13 closes, and the vibration operation ends.

[0041] In other words, the time relay 14 and the solenoid valve 13 are set up in this application to work together to achieve standardized control of the vibration operation time, which not only improves the vibration operation efficiency and ensures the product quality of precast concrete components, but also helps to save construction costs.

[0042] The interface of male connector 3 has a tapered structure.

[0043] In one embodiment of this application, the interface portion of the male connector 3 is an outwardly flared conical structure such as a horn or a cone, which makes it easier for the male connector 3 and the female connector 9 to connect.

[0044] A limiting block 2 is provided on each side of the base 1 in the direction of movement. The limiting block 2 is used to limit the range of movement of the base 1 along the track.

[0045] In one embodiment of this application, although the vibrator is set at a fixed position on the mold 8, during the movement of the mold 8, the vibrator is affected by factors such as vibration, and the position of the female connector 9 of the vibrator may be slightly offset. In addition, due to the positioning error of the positioning component itself, these external influences will make it impossible for the male connector 3 and the female connector 9 to be completely aligned, resulting in a small range of error between the male connector 3 and the female connector 9 in the alignment direction.

[0046] When the telescopic mechanism drives the male connector 3 to extend towards the female connector 9, the female connector 9 can slide into the male connector 3 along the tapered interface of the male connector 3 because the male connector 3 has a tapered structure. Since the base 1 is slidably set on the track, the base 1 and the male connector 3 adaptably move in the front and back directions to ensure the accuracy of the front and back docking of the male connector 3 and the female connector 9.

[0047] The limit block 2 is set on the track to limit the range of movement of the base 1 in the front and back directions, ensuring that the base 1 is within the mating error range of the male connector 3 and the female connector 9.

[0048] The base 1 is provided with multiple guide rods 15, and a floating plate 7 is guided to move along the guide rods 15 in the vertical direction. An upper spring 16 and a lower spring 17 are sleeved on the guide rods 15. The upper spring 16 is located above the floating plate 7, and the lower spring 17 is located below the floating plate 7. A nut is provided at the top of the guide rod 15 to limit the upper spring 16 and prevent the upper spring 16 from falling off the guide rod 15. The male connector 3 and the telescopic mechanism are both provided on the floating plate 7.

[0049] In one embodiment of this application, when the telescopic mechanism drives the male connector 3 to extend toward the female connector 9, since the interface of the male connector 3 is a conical structure, the female connector 9 can slide into the male connector 3 along the interface of the conical structure; since the floating plate 7 can float up and down along the guide rod 15, the floating plate 7 and the male connector 3 can move adaptively up and down to ensure the accuracy of the male connector 3 and the female connector 9 in the up and down direction.

[0050] The telescopic mechanism includes at least one telescopic rod 5. The main body of the telescopic rod 5 is fixed on the floating plate 7. The telescopic end of the telescopic rod 5 is fixedly connected to the connecting plate 6. The male connector 3 is fixed in the middle of the connecting plate 6.

[0051] In one embodiment of this application, the telescopic mechanism is provided with two telescopic rods 5, which are located on both sides of the male connector 3. The male connector 3 is fixed in the middle of the connecting plate 6, and the telescopic ends of the two telescopic rods 5 are fixed on both sides of the connecting plate 6 to make the force on the connecting plate 6 more even. When the telescopic ends of the telescopic rods 5 extend, they drive the connecting plate 6 and the male connector 3 to extend outward. When the telescopic ends of the telescopic rods 5 retract, they drive the male connector 3 of the connecting plate 6 to retract inward.

[0052] In this embodiment, the telescopic tube 4 is a corrugated pipe; the telescopic rod 5 can be a pneumatic rod, an electric push rod, or other structures; when the telescopic rod 5 is an electric push rod, the electric push rod is electrically connected to the controller. After receiving a positioning signal, the controller controls the electric push rod to extend, and after receiving a signal from the time relay 14 to end operation, it controls the electric push rod to retract; when the telescopic rod 5 is a pneumatic rod, a pneumatic control valve is connected to the pneumatic rod, and the pneumatic control valve is electrically connected to the controller. The controller controls the pneumatic control valve to realize the telescopic movement of the pneumatic rod.

[0053] It is understood that the above description is merely exemplary and the embodiments of this application do not limit the scope of the application.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
