Description

Technical Field

[0001] The utility model relates to the technical field of blasthole charging, in particular to an automatic charging vehicle for emulsion explosives. Background Art

[0002] Emulsion explosives are a type of water-in-oil emulsion industrial explosive that has the characteristics of strong water resistance and good blasting performance. They are widely used for charging water-containing blastholes. The specific method is to extend the drug delivery tube to the bottom of the blasthole and then load the emulsion explosive into the blasthole.

[0003] In the prior art, emulsion explosives are typically loaded using an emulsion loading vehicle. This vehicle must be parked next to a blasthole, where workers manually remove the explosive delivery tube and drag it into place. Once loading is complete, the tube must be manually pulled out of the hole and docked with the next one. The vehicle must then be moved and the above steps repeated until all holes are loaded.

[0004] Since part of the emulsion explosive will be temporarily stored in the drug delivery tube during charging, which will increase the weight of the drug delivery tube, the manual labor of dragging the drug delivery tube will be very large, making it difficult to improve the charging efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an automatic charging vehicle for emulsion explosives, which can reduce manual labor and improve the charging efficiency of emulsion explosives.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] The utility model provides an automated charging vehicle for emulsion explosives, comprising: a vehicle body, a charging tank and a rotor pump, wherein the charging tank and the rotor pump are arranged on the vehicle body, and the rotor pump is connected to the charging tank. The utility model further comprises: a drug delivery pipe, a pipe disc and a first drive motor, one end of the drug delivery pipe is connected to the rotor pump, the pipe disc is rotatably connected to the vehicle body, the first drive motor is fixedly connected to the vehicle body, the drug delivery pipe disc is arranged on the pipe disc, and the driving end of the first drive motor is fixedly connected to the rotating shaft on one side of the pipe disc.

[0008] By adopting the above technical solution, when the automated emulsion explosives charging vehicle is charging a blasthole, the vehicle body moves to the blasthole using a positioner. The drive end of the first drive motor rotates, driving the tube reel. The drug delivery tube is then extended from its coiled state and inserted into the bottom of the blasthole. The rotor pump activates, transferring the emulsion explosive from the charging tank to the drug delivery tube. The emulsion explosive is then loaded into the blasthole through the drug delivery tube. After loading is complete, the drive end of the first drive motor rotates in the opposite direction, and the drug delivery tube is rewound onto the tube reel, thus completing the charging of a single blasthole. When the next blasthole needs to be charged, the vehicle body moves to the next blasthole and the above steps are repeated. Throughout the charging process, workers do not need to drag the drug delivery tube; the extension and retraction of the drug delivery tube are automated by the first drive motor. This significantly reduces manual labor and improves the efficiency of emulsion explosives charging.

[0009] Optionally, a central console, a signal transceiver, and a Beidou locator are provided on the vehicle body; the central console is communicatively connected to the vehicle body, the rotor pump, the first drive motor, the signal transceiver, and the Beidou locator respectively.

[0010] By adopting the above technical solution, the central console can send and receive signals through the signal transceiver to realize information networking interaction, and quickly find the blast hole through the positioning of the Beidou locator. The staff can also view the vehicle body position, blast hole position, rotor pump speed, first drive motor working status and other information on the central console.

[0011] Optionally, a plurality of weight sensors are provided on the vehicle body, the medicine tank is provided on the vehicle body through the plurality of weight sensors, and the weight sensors are communicatively connected with the central console.

[0012] By adopting the above technical solution, the weight sensor can weigh the weight of the charge tank, thereby realizing real-time monitoring of the remaining amount of emulsion explosive in the charge tank.

[0013] Optionally, the automated charging vehicle for emulsion explosives further includes: a blasthole measuring mechanism, wherein the blasthole measuring mechanism is disposed on the vehicle body and is communicatively connected to the central console.

[0014] By adopting the above technical solution, the blasthole measuring mechanism can measure the blasthole and display it through the central console.

[0015] Optionally, the borehole measuring mechanism includes a second drive motor, a measuring rope, a buoy, a counterweight, and a tension sensor. The second drive motor is installed on the vehicle body, one end of the measuring rope is connected to the drive end of the second drive motor, the buoy is movably connected to the measuring rope, the counterweight is connected to the other end of the measuring rope, and both ends of the tension sensor are respectively connected to the measuring rope, and the second drive motor and the tension sensor are respectively communicated with the center console.

[0016] By employing this technical solution, before charging, the central control console controls the rotation of the drive end of the second drive motor. The measuring rope, buoy, counterweight, and tension sensor are lowered into the blasthole. The tension sensor continuously measures the tension in the measuring rope, which is the sum of the weight of the buoy and counterweight. When the buoy and counterweight reach the surface of the water, the buoy floats due to the buoyancy of the water, while the counterweight continues to descend. At this point, the tension in the measuring rope is solely the weight of the counterweight. The central control console uses the encoder in the second drive motor to record the length of the lowered measuring rope, thereby determining the distance from the muzzle to the water surface. If there is no water, the buoy continues to descend. When the counterweight reaches the bottom of the hole, the tension in the measuring rope is solely the weight of the measuring rope itself. Thereafter, the tension remains constant. Recording this length of the measuring rope determines the hole depth. By measuring the hole depth and water depth, personnel can determine whether water is present in the hole and, therefore, whether the drug delivery tube needs to be extended to the bottom of the hole, further improving the charging efficiency of emulsion explosives.

[0017] Optionally, the blasthole measurement mechanism further includes: a temperature sensor, the temperature sensor is communicatively connected to the central console, and the temperature sensor is arranged on the counterweight.

[0018] By adopting the above technical solution, the temperature sensor can measure the hole temperature, thereby realizing the monitoring of the hole temperature.

[0019] Optionally, the vehicle body has a mounting groove, a bracket is fixed in the mounting groove, the pipe disc is rotatably connected to the vehicle body through the bracket, and the first drive motor is fixedly connected to the vehicle body through the bracket.

[0020] By adopting the above technical solution, providing the installation groove can prevent the pipe reel and the first drive motor from protruding from the vehicle body, and providing the bracket can improve the convenience of installing the first drive motor and the pipe reel.

[0021] Optionally, the bottom edge of the mounting groove is rotatably connected to a guide frame, the guide frame can be received in the mounting groove, the end of the guide frame away from the rotating end is movably connected to a fixed pulley bracket, the fixed pulley bracket has a first guide wheel and a second guide wheel rotatably connected side by side, and the drug delivery tube is passed through the first guide wheel and the second guide wheel.

[0022] By adopting the above technical solution, after the vehicle body moves to a position suitable for loading based on the Beidou locator, the guide frame is opened and the guide frame contacts the ground. The first guide wheel and the second guide wheel can support and guide the drug delivery tube, that is, guide the drug delivery tube to extend into the gun hole, or guide the drug delivery tube to be pulled out of the gun hole, thereby realizing automatic loading.

[0023] Optionally, a flow meter is installed between the medicine loading tank and the rotor pump, and the flow meter is communicatively connected to the central console.

[0024] By adopting the above technical solution, the flow meter can count the amount of emulsion explosive used, thereby realizing dual measurement of the emulsion explosive with the weight sensor, thereby further improving the accuracy of the emulsion explosive usage.

[0033] This embodiment provides an automated charging vehicle for emulsion explosives.

[0034] refer to Figure 1 and Figure 2 An automated emulsion explosive charging vehicle comprises a vehicle body 1, a charging tank 2, a rotor pump 3, a drug delivery pipe, a pipe reel, and a first drive motor 4. The charging tank 2 and the rotor pump 3 are both mounted on the vehicle body 1, and the input ends of the charging tank 2 and the rotor pump 3 are connected. The rear portion of the vehicle body 1 has a mounting slot, into which a bracket is fixedly connected. The pipe reel is rotatably connected to the vehicle body 1 via the bracket. The first drive motor 4 is fixedly connected to the vehicle body 1 via the bracket. One end of the drug delivery pipe is connected to the output end of the rotor pump 3, and the drug delivery pipe reel is disposed on the reel. The driving end of the first drive motor 4 is fixedly connected to a rotating shaft on one side of the reel.

[0035] The vehicle body 1 is movable, the charging tank 2 is used to charge the emulsion explosive, the rotor pump 3 is used to transport the mixed emulsion explosive in the charging tank 2 to the blasthole through the drug delivery pipe, and the pipe reel can automatically reel or extend the drug delivery pipe under the drive of the first drive motor 4, so as to achieve the purpose of reducing manual labor and improving the charging efficiency of the emulsion explosive.

[0036] A guide frame is rotatably connected to the bottom edge of the mounting slot and can be stored within the mounting slot. A fixed pulley bracket is movably connected to the end of the guide frame away from the rotating end. A first guide wheel and a second guide wheel are rotatably connected side by side within the fixed pulley bracket. The drug delivery tube is passed through the first and second guide wheels. The guide frame guides the drug delivery tube, and the first and second guide wheels support and guide the drug delivery tube, thereby guiding the drug delivery tube into or out of the blasthole, thereby achieving automatic charging.

[0037] The automated emulsion explosive charging vehicle also includes a central console 5, a signal transceiver 6, a Beidou locator 7, a weight sensor 8, and a borehole measurement mechanism, all mounted on the vehicle body 1. Multiple weight sensors 8 are provided, and the charging tank 2 is mounted on multiple weight sensors 8, thereby enabling the weight sensors 8 to be mounted on the vehicle body 1. The central console 5 is communicatively connected to the vehicle body 1, the rotor pump 3, the signal transceiver 6, the Beidou locator 7, the weight sensor 8, and the borehole measurement mechanism. By collecting information from these modules, the central console 5 displays information on the vehicle body 1 position, the borehole position, the operating status of the rotor pump 3, signal transmission and reception information, and the remaining emulsion explosive for easy viewing by personnel.

[0038] refer to Figure 1 and Figure 2 The borehole measurement mechanism includes a second drive motor 9, a measuring rope, a buoy, a counterweight, a tension sensor 10, and a temperature sensor 11. The center console 5 is in communication with the second drive motor 9, the tension sensor 10, and the temperature sensor 11. The second drive motor 9 is mounted on the vehicle body 1, specifically at the opening edge of the mounting slot. One end of the measuring rope is fixedly connected to the drive end of the second drive motor 9, the counterweight is fixedly connected to the other end of the measuring rope, the two ends of the tension sensor 10 are respectively connected to the measuring rope, the buoy is movably connected to the measuring rope, and the temperature sensor 11 is mounted on the counterweight.

[0039] When measuring the borehole depth, water depth, and borehole temperature, the central console 5 controls the drive end of the second drive motor 9 to rotate, and the measuring rope, buoy, counterweight, tension sensor 10, and temperature sensor 11 are lowered into the borehole. The tension sensor 10 continuously measures the tension in the measuring rope. At this point, the tension in the measuring rope is the sum of the weight of the buoy, counterweight, and temperature sensor 11. When the buoy and counterweight reach the surface of the water, the buoy floats on the surface due to the buoyancy of the water, and the counterweight continues to be lowered. The tension in the measuring rope is now only the weight of the counterweight plus the temperature sensor 11. Recording the length of the lowered measuring rope provides the distance from the muzzle to the water surface. If there is no water, the buoy continues to descend. When the counterweight reaches the bottom of the hole, the tension in the measuring rope is only the weight of the measuring rope. The tension will not change thereafter. Recording the length of the measuring rope provides the borehole depth. The borehole temperature is then measured by the temperature sensor 11 on the counterweight.

[0040] In an optional embodiment of the present application, a flow meter 12 is further installed between the charging tank 2 and the rotor pump 3. The flow meter 12 is communicatively connected to the central control console 5. The flow meter 12 can count the amount of emulsion explosive used, thereby realizing dual measurement of the emulsion explosive with the weight sensor 8, thereby further improving the accuracy of the emulsion explosive usage.

[0041] It should be understood that the vehicle body 1 can be a vehicle body with a person driving it or a vehicle body without a person driving it, which is not limited here.

[0042] The implementation principle of an automated emulsion explosive charging vehicle in accordance with an embodiment of the present application is as follows: when the automated charging robot is operating, the vehicle body 1 moves to the side of the blasthole, the blasthole measuring mechanism first measures the blasthole, and then determines the lowering length of the drug delivery tube based on the measurement results. The driving end of the first drive motor 4 then rotates to extend the drug delivery tube toward the blasthole, and the rotor pump 3 operates to load the explosives. During loading, the emulsion explosives discharge the water in the hole. After loading is completed, the vehicle body 1 moves to the next blasthole based on the information displayed on the center console 5 and repeats the above steps. Since the staff does not need to drag the drug delivery tube, the extension and storage of the drug delivery tube can be automated by the first drive motor 4, thereby greatly reducing the amount of manual labor and improving the efficiency of emulsion explosive charging.

[0043] The above embodiments are merely a detailed description of the technical solutions of the present invention. However, the description of the above embodiments is intended only to facilitate understanding of the present invention and should not be construed as limiting the present invention. Any changes or substitutions that can be readily conceived by a person skilled in the art within the technical scope disclosed in the present invention are intended to fall within the scope of protection of the present invention.
