Description

Technical Field

[0001] The invention relates to the technical field of blasting, and in particular to a laser blasting concrete safety driving device. Background Art

[0002] Demolition projects play an irreplaceable and important role in national economic construction, such as urban renewal and industrial upgrading and transformation. However, traditional blasting demolition and mechanical demolition methods are noisy, dusty, and high-risk, and can no longer meet new needs, resulting in frequent safety accidents and environmental pollution. In addition, during the demolition of old urban buildings, the traditional mechanical drill bit often encounters the problem of the steel bars in the concrete being difficult to break during the excavation process, which will cause the drill bit to get stuck and unable to excavate. At this time, it is difficult for a purely mechanical drill bit to continue drilling forward, and it is difficult to retreat and retract it because it is tightly wrapped around it. Usually, the only choice is to discard the drill bit or break all the concrete around the drill bit to remove the drill bit, which limits both the economic benefits and the excavation speed.

[0085] Embodiment 1

[0086] See also Figure 1-11 , this embodiment 1 provides a laser blasting concrete safety driving device. In this embodiment, the laser blasting concrete safety driving device provided by the present application specifically includes a laser, a moving module, a dust removal module and a control module. The laser is used to generate laser energy to destroy the concrete structure to be demolished; the moving module is fixedly connected to the laser, and the moving module is used to drive the laser to move to the corresponding position of the concrete structure to be demolished; the dust removal module is arranged near the light outlet of the laser, and the dust removal module is used to remove dust in front of the laser when the laser generates laser energy to destroy the concrete structure to be demolished; the control module is respectively connected to the laser, the dust removal module and the moving module, and the control module is used to start or shut down the laser, the dust removal module and the moving module respectively.

[0087] The embodiment of the present invention provides a laser blasting concrete safety driving device, including a laser, a mobile module, a dust removal module and a control module, wherein the mobile module is fixedly connected to the laser, the dust removal module is arranged near the light outlet of the laser, and the control module is respectively connected to the laser, the dust removal module and the mobile module; the laser, the dust removal module and the mobile module are respectively started or shut down by the control module, the control module starts the laser to generate laser energy to destroy the concrete structure to be demolished, the control module starts the mobile module to drive the laser to move to the corresponding position of the concrete structure to be demolished, and the control module starts the dust removal module to remove dust in front of the laser when the laser generates laser energy to destroy and demolish the concrete structure to be demolished. The non-contact laser blasting concrete safety driving device provided by the embodiment of the present application replaces the traditional contact mechanical drill blasting method to achieve a safer, more economical and environmentally friendly demolition effect, and at the same time, by flexibly controlling the movement of the laser and matching the dust removal structure, the operability of the device is improved, and at the same time, the efficiency and safety of the concrete demolition process can be improved.

[0088] As an implementable approach, Figure 1-3 As shown, the mobile module involved in the present application includes a base and a robotic arm. The base has a accommodating space, and the control module is arranged in the accommodating space; one end of the robotic arm is fixed on the base, and the other end of the robotic arm is fixedly connected to the laser.

[0089] The robot arm involved in the present application is a three-degree-of-freedom robot arm, which can flexibly control the movement of the laser in a three-dimensional space. The three-degree-of-freedom robot arm can be realized by using existing technology.

[0090] It can be understood that the laser of the present application is provided with an optical element, through which the direction and intensity of the laser beam are focused and precisely controlled to ensure that there is sufficient energy for concrete drilling or demolition.

[0091] As an implementable manner, a pipeline channel is provided in the robotic arm. The dust removal module involved in the present application includes an air compressor, a mounting frame and a pair of dust removal pipelines. The air compressor is fixed on the base, and the air compressor is arranged adjacent to the robotic arm; the mounting frame includes a first mounting plate, a second mounting plate and a third mounting plate, the third mounting plate is vertically connected between the first mounting plate and the second mounting plate, pipeline fixing parts are symmetrically provided on the outer side walls of the first mounting plate and the second mounting plate, the laser is fixedly connected to the second mounting plate, and the third mounting plate is fixed to the end of the other end of the robotic arm; one end of a dust removal pipeline passes through the pipeline fixing part of the first mounting plate and is located near the light outlet of the laser, the other end of a dust removal pipeline passes through the pipeline channel of the robotic arm and is connected to the air compressor, one end of another dust removal pipeline passes through the pipeline fixing part of the second mounting plate and is located near the light outlet of the laser, the other end of the other dust removal pipeline passes through the pipeline channel of the robotic arm and is connected to the air compressor, and a pair of dust removal pipelines are symmetrically distributed on both sides of the laser.

[0092] It is understandable that when the laser acts on the concrete surface, molten glass crystal fragments will be generated and solidified on the surface, affecting the drilling depth. By setting up a special mounting bracket to fix the dust removal pipeline on both sides of the laser periphery, the dust and debris generated around the pores during the drilling process can be blown away in time.

[0093] Specifically, the mounting frame is configured to be assembled from a first mounting plate, a second mounting plate, and a third mounting plate, so that the third mounting plate is located between the laser and the mechanical arm, and the laser is located between the first mounting plate and the second mounting plate, so that the two dust removal pipelines can be fixed through the mounting frame, and the air outlets of the two dust removal pipelines are located near the light outlet of the laser. By starting the air compressor, the two dust removal pipelines can be exhausted, and dust can be removed in front of the laser when the laser is demolished by blasting.

[0094] As an implementable manner, one end of a pair of dust removal pipes is deflected at a preset angle in a direction close to the laser, and a meeting point of the pair of dust removal pipes in front of the laser is at a preset distance from the laser.

[0095] The preset distance is the distance between the intersection of the extension lines of a pair of dust removal pipes at one end of the laser and the light outlet of the laser. During laser blasting demolition, the laser cannot be moved too close to the concrete structure to be demolished nor too far away. Generally, the laser can be driven by a mobile device to a preset distance between its light outlet and the demolished surface of the concrete structure to be demolished. The preset distance can be set to 13 cm.

[0096] As an implementable approach, Figure 3As shown, the dust removal module involved in the present application also includes a ventilation structure and an air-cooling duct. The ventilation structure is arranged at the light outlet of the laser, and a plurality of exhaust outlets are arranged on the ventilation structure. One end of the air-cooling duct is connected to the ventilation structure, and the other end of the air-cooling duct passes through the laser, the third mounting plate, and the pipeline channel of the robotic arm in sequence and is connected to the air compressor.

[0097] Specifically, since laser blasting generates high temperature, the present application adds a ventilation structure and an air-cooling duct at the light outlet of the laser to cool the laser and the optical elements therein to prevent the device from being damaged by overheating.

[0098] As an implementable method, the control module involved in the present application includes a main control chip U1, a power supply circuit, a temperature sampling circuit, a current sampling circuit and a relay control circuit. The power supply circuit is electrically connected to the laser, the robotic arm and the main control chip U1 respectively; the temperature sampling circuit is electrically connected to the power supply circuit and the main control chip U1 respectively; the current sampling circuit is electrically connected to the power supply circuit, the robotic arm and the main control chip U1 respectively; the relay control circuit is electrically connected to the power supply circuit, the main control chip U1 and the air compressor respectively.

[0099] Specifically, the temperature sampling circuit is used to sample the temperature at the laser light outlet in real time. When the sampled temperature reaches the preset temperature, an alarm is issued or the laser is controlled to shut down the light. Two temperature sampling circuits of the present application can be set, one for sampling the temperature of the laser light outlet, and one for sampling the temperature of the robot arm to avoid the robot arm's operating temperature being too high (correspondingly, a thermistor can be set on the robot arm); the current sampling circuit is used to sample the working current of the robot arm to avoid damage to the robot arm due to excessive current.

[0100] It should be noted that the laser of the present application includes a laser body and a laser control part, the laser control part is used to control the light emission of the laser body, wherein the laser body is powered by an external high-power power supply, and the laser control part is powered by the power supply circuit involved in the present application and connected to the main control chip of the present application.

[0101] Similarly, the air compressor of the present application includes an air compressor body and a control valve, wherein the control valve is used to control the on-off connection between the air compressor and the air cooling duct and the dust removal duct, wherein the air compressor body is powered by an external high-power power supply, and the control valve is connected to the relay control circuit of the present application.

[0102] The relay control circuit is used to control the connection and disconnection of the control valve between the air compressor and the air cooling pipeline and the dust removal pipeline. When the control valve of the air compressor is connected, the air cooling pipeline and the dust removal pipeline will discharge air to cool the laser through the air cooling pipeline, and at the same time, the blasting surface in front of the laser is dusted through the dust removal pipeline.

[0106] Specifically, when the main control chip U1 gives a high level to the PA5 pin, the digital transistor Q4, the optocoupler U15, and the transistor Q3 are all turned on. At this time, the coil at the input end of the relay RE3 flows with current and generates a magnetic field, thereby attracting the moving contact of the relay to achieve the on and off of the control valve of the air compressor. Among them, the seventh resistor R30, the eighth resistor R31, and the ninth resistor R46 are used for current limiting to protect other components in the circuit, and the diode D3 plays a role in protecting the transistor Q3.

[0107] As a feasible approach, Figure 8-11 As shown, the power supply circuit involved in the present application includes a 12V power supply, a first step-down circuit, a second step-down circuit, a third step-down circuit, and a fourth step-down circuit, wherein the 12V power supply is used to power the laser control part of the laser, and the specific circuit connection diagram of the first step-down circuit is shown in the attached Figure 8 ,like Figure 8 As shown, the input end of the first buck circuit is connected to the 12V power supply, and the first buck circuit is used to convert the 12V voltage into a 5V output voltage, and its output end is VCC_INPUT; the specific circuit connection diagram of the second buck circuit is shown in the attached Fig. 9 ,like Fig. 9As shown, the input end of the second buck circuit is connected to the output end of the first buck circuit, the second buck circuit is used to convert the 5V voltage into a 3.3V voltage, and its output end is VCC_3.3V.
