[0002] Tamping is a construction method for compacting soil to increase the foundation strength by repeatedly releasing a heavy hammer or repeating vibration at a certain height, and this method is usually implemented by tamping equipment.

[0003] The tamping construction process of traditional vibration compaction construction equipment has a certain degree of monotony and repetition, requiring operators to maintain a highly concentrated working state for a long time, which has certain potential safety hazards. In terms of personnel allocation, the traditional construction process not only requires a driver for the tamping equipment, but also requires multiple workers to observe whether the position of the tamp plate on the tamping hydraulic cylinder reaches the expected value to cooperate with the tamping equipment. The utilization efficiency of personnel is low, and during the observation process, there are also certain observation errors in the actual position of the tamp plate, and the tamping effect needs to be improved. In terms of construction quality control, the traditional machinery is manually operated by the driver, and the construction information is difficult to quantify, and there is no unified and scientific evaluation index for the construction quality of each time. In addition, the working environment at the slope is harsh and the construction conditions are poor, which will consume more energy of the driver. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the embodiments and the drawings. The illustrative embodiments and descriptions of the present application are only used to explain the present application and do not limit the present application.

[0028] In the first aspect, as Figure 1 shown, the embodiment of the present application provides an automatic ramming vibration compaction control system, which includes a controller, an information acquisition unit, and an action execution unit.

[0029] The controller can be, for example, a programmable logic controller, a distributed control system, an industrial computer control system, a fieldbus control system, a microcontroller, etc. The controller can be connected to the control system of the ramming vibration compaction equipment by wire or wireless communication. In other embodiments, the control system of the ramming vibration compaction equipment can directly serve as the controller in the embodiment of the present application.

[0030] The information acquisition unit is connected to the controller to feed back the position information of the ram plate to the controller. Among them, the information acquisition unit can be connected to the controller by wire or communicate wirelessly.

[0031] The action execution unit is connected to the controller. The action execution unit is used to drive the ram plate to perform ramming motion. Among them, the action execution unit can be connected to the controller by wire or communicate wirelessly.

[0032] In the automatic ramming vibration compaction control system provided by this application, the information acquisition unit can detect the position information of the ram plate, eliminating the need for manual observation. After the information acquisition unit feeds back the position information to the controller, the position information can be stored, such as the travel amount of the ram plate during each ramming. This is conducive to the quantification of construction information. The controller controls the action of the action execution unit according to the position information fed back by the information acquisition unit to drive the ram plate to move, thereby achieving precise control of the travel amount of the ram plate and ensuring good ramming effect.

[0033] In some alternative embodiments, the information acquisition unit includes a distance measurement sensor. The distance measurement sensor is used to be installed on the ramming hydraulic cylinder to detect the position information of the ram plate.

[0034] In the embodiments of this application, the distance measurement sensor can be configured as, for example, an ultrasonic sensor, a lidar, an infrared sensor, a radar sensor, an optical distance measurement sensor, a sonar sensor, a structured light sensor, etc. The distance measurement sensor in the embodiments of this application can be configured as a laser rangefinder, which has the advantages of high measurement accuracy and rapid response and is suitable for measurement occasions where the ram plate moves frequently.

[0035] In some alternative embodiments, the information acquisition unit further includes an inclination sensor. The inclination sensor is used to be installed on the ramming hydraulic cylinder to monitor the angle information of the ram plate. In other embodiments, the information acquisition unit can further include an emergency stop switch. The emergency stop switch is connected to the controller and is used as a digital quantity signal to be input into the controller for soft emergency stop.

[0036] In the embodiments of this application, by setting the inclination sensor, the inclination state of the ram plate can also be measured. For example, when the included angle between the ram plate and the horizontal plane is too large, the controller can control the ramming hydraulic cylinder to stop acting through the action execution unit so that the staff can adjust the ram plate, preventing the ram plate from experiencing structural damage during ramming due to an excessive inclination angle. At the same time, adjusting the ram plate immediately can also ensure good ramming effect.

[0037] In some alternative embodiments, analog quantity transmission interfaces are respectively configured on the distance measurement sensor and the controller.

[0038] In the embodiment of the present application, the distance measuring sensor and the controller are provided with an analog quantity transmission interface. There are fewer signal lines between them, usually only two, which can bring convenience to the wiring work. Moreover, the distance measuring sensor and the controller are connected by an analog quantity transmission interface, and the anti-interference ability is strong, which can ensure the accuracy of the position information of the rammer plate.

[0039] In some optional embodiments, CAN bus interfaces are respectively configured on the inclination sensor and the controller.

[0040] In the embodiment of the present application, through the setting of the CAN bus interface, data communication can be carried out between the inclination sensor and the controller through CANOPEN in the CAN communication protocol. In this way, the inclination sensor and the controller can maintain real-time communication and achieve fast response, that is, when the inclination angle of the rammer plate is too large, it can be immediately detected to stop the action of the rammer plate. The tamping vibration compaction equipment can also adjust the boom based on the feedback information of the inclination sensor to realize the angle adjustment of the rammer plate.

[0041] In some optional embodiments, the automatic tamping vibration compaction control system further includes a display, and the display is connected to the controller.

[0042] In the embodiment of the present application, CAN bus interfaces can be respectively configured on the display and the controller so that the two can communicate based on the CAN communication protocol. The display can visually express the position information of the rammer plate fed back by the information acquisition unit, which is convenient for the staff to directly observe, and further provides convenience for the staff to conduct manual analysis of the tamping effect. At the same time, the display undertakes the responsibility of human-machine interaction HMI. For example, the display can be configured as an industrial touch screen, which displays the device status and provides a device interface for the user to output parameters. Parameters such as the single tamping movement distance, tamping duration, number of cycles and the back-and-forth distance of the rammer plate can be set through the display, and signals such as automatic program start, stop, mode selection, etc. are provided. The signals are transmitted to the controller through the CAN bus; the display and the controller respectively provide corresponding program burning interfaces. The controller can burn the control program through the Ethernet network port, and the display can burn the program with a USB port.

[0043] In some optional embodiments, the action execution unit includes an electromagnetic reversing valve, and the electromagnetic reversing valve is used to be installed on the tamping hydraulic cylinder to control the flow direction of the liquid medium in the tamping hydraulic cylinder.

[0044] In the embodiment of the present application, according to the position information of the rammer plate fed back by the information acquisition unit, the controller can control the electromagnetic reversing valve to act so that the liquid medium in the tamping hydraulic cylinder flows reversely, thereby realizing the tamping action of the rammer plate.

[0045] In some alternative embodiments, the action execution unit further includes a proportional pressure reducing valve, which is used to be installed on the tamping hydraulic cylinder to adjust the pressure of the liquid medium in the tamping hydraulic cylinder.

[0046] In the embodiments of the present application, the controller can control the proportional pressure reducing valve to act to adjust the pressure of the liquid medium in the tamping hydraulic cylinder, so as to achieve the adjustment of the tamping speed, and further achieve the adjustment of the tamping effect. In actual implementation, the proportional pressure reducing valve and the controller can be respectively configured with PWM signal ports.

[0047] In some alternative embodiments, the automatic tamping vibration compaction control system further includes a cloud device, and the cloud device is communicatively connected to the controller.

[0048] In the embodiments of the present application, the cloud device may specifically include an Internet of Things module, a cloud platform, a GPS antenna, and a terminal device. The controller can upload the position information of the tamper plate and the status information of the controller to the cloud device, or download instructions from the cloud device, such as start, stop, standby instructions; the terminal device is connected to the cloud platform, and remote monitoring can be performed through the terminal device. Among them, the terminal device can be configured as a mobile device such as a mobile phone or a computer, and the terminal device can exchange data with the cloud platform through a 4G network.

[0049] In a second aspect, the present application provides an automatic tamping vibration compaction device, including any automatic tamping vibration compaction control system as in the first aspect; wherein, the action execution unit is connected to the tamping hydraulic cylinder in the automatic tamping vibration compaction device to control the action of the tamping hydraulic cylinder.

[0050] The automatic tamping vibration compaction device provided by the present application can accurately control the travel amount of the tamper plate through the position information of the tamper plate collected by the automatic tamping vibration compaction control system, reduce manual participation, realize automatic tamping vibration compaction, and reduce the labor pressure of the staff.

[0051] In actual use, a series of parameters of automatic tamping can be input through the display, including, for example, the single tamping moving distance, the tamping duration, the number of cycles, the back-and-forth distance of the tamper plate, etc.

[0052] When in use, such as Figure 2As shown, the tamping and vibrating compaction equipment is mechanically positioned, and parameters are set through the display, such as the single tamping moving distance, tamping duration, number of cycles, back-and-forth moving distance of tamping, starting position of the tamper plate movement, and ending position of the tamper plate movement. The controller controls the tamper plate to drop for tamping, and the timer of the controller starts timing. After the tamper plate maintains the tamping duration, the tamper plate is lifted. The moving distance of the tamper plate is detected by the ranging sensor. After the tamper plate reaches the set starting / ending position, the counter of the controller makes a count, and the controller controls the tamper plate to move in the reverse direction (i.e., the tamper plate drops again for the tamping action). The above process is iterated until the value of the counter reaches the number of cycles, and the tamping ends.
