Description

Technical Field

[0001] The utility model relates to the technical field of sand loading in a fracturing sand tank truck, in particular to an automatic vehicle positioning device. Background Art

[0002] At present, the fracturing sand tanker loading process is completely dependent on manual operation, and its automation level is low. The manual loading process of the fracturing sand tanker and the existing problems are as follows:

[0003] When the fracturing sand tank truck arrives at the designated sand storage tank loading port, it needs to reverse into the sand storage tank loading port and start loading sand from the sand inlet near the front of the truck. At this time, an operator is required to climb onto the sand storage tank platform, observe the relative positions of the sand inlet and sand outlet on the fracturing sand tank truck through the sand outlet, and direct the fracturing sand tank truck driver to control the vehicle forward or backward and stop through verbal calls, so that the sand outlet of the sand storage tank is aligned with the sand inlet on the fracturing sand tank truck.

[0004] Since the driver needs reaction time to control the vehicle during the command process, the sand outlet and the sand inlet cannot be accurately and quickly aligned, and the operator needs to repeatedly command the driver to adjust the vehicle position to finally align the sand outlet and the sand inlet. After alignment, the operator manually opens the gate at the bottom of the sand storage tank and starts the sand loading operation, while observing whether the sand inlet on the fracturing sand tanker is full. After it is full, the gate at the bottom of the sand storage tank is manually closed, and the driver is commanded to control the vehicle to move forward and load the sand at the next sand inlet.

[0005] Because there are usually 2 or 3 sand inlets on a fracturing sand tank truck, the operator needs to repeat the command work 2-3 times, which wastes a lot of time, has high work intensity and low work efficiency, and easily causes vehicles to wait in queues and low vehicle utilization. If multiple sand tanks are operating at the same time, an operator needs to be assigned to each sand tank to command, which consumes a lot of manpower and has high labor costs. At the same time, when manually observing whether the fracturing sand tank truck is full, there is a problem that it is impossible to measure and monitor the amount of sand loaded and the amount of sand remaining in the sand tank.

[0027] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0028] Please refer to the attached Figure 1-2 The vehicle automatic positioning device includes a fracturing sand tank truck 1, a sand storage tank 2 and a buffer platform 5 for installing the sand storage tank 2. The lower end of the sand storage tank 2 is connected with a sand outlet 3, the fracturing sand tank truck 1 is provided with a plurality of sand inlets 4, and a through opening 6 is provided on the buffer platform 5 corresponding to the position of the sand outlet 3.

[0029] During specific use, an automatic gate mechanism 14 is connected to the sand outlet 3, an image visual recognition monitoring camera 7 is provided at the bottom of the buffer platform 5 near the opening 6, and sand inlet position positioning devices 8 are also provided on both sides of the opening 6; it also includes additional parking space indication equipment and a control room, the parking space indication equipment includes a parking space indicator light 9, a floor 10, a motion recognition device 11 and a voice broadcasting device 12 arranged at the bottom of the buffer platform 5; the control room is used to connect and control various electronic equipment.

[0030] A material level sensor 13 is also connected to the sand storage tank 2, and a parking indicator light 9 is arranged opposite to the motion identification device 11. The parking indicator light 9 is arranged close to the front side of the vehicle, and the parking indicator light 9 is a three-color integrated matrix indicator light.

[0031] The control room includes monitoring display screen, intercom, UPS power supply and control console for control.

[0032] During the specific implementation, the fracturing sand tank truck arrives at the tank area, the driver opens the sand inlet of the fracturing sand tank truck and starts to reverse into the bottom of the sand storage tank, the system starts the automatic sand loading mode, and identifies the number of sand inlets of the fracturing sand tank truck that have been opened, recorded as N, and additional left and right reversing guide lines are set to assist reversing when reversing, the image visual recognition monitoring camera, the sand inlet position detection sensor and the tank mouth alignment three-color integrated matrix indicator light are started and used, and the voice broadcast device gives a voice prompt: "Please pay attention when reversing."

[0033] During the reversing process of the fracturing sand tank truck, the image visual recognition monitoring camera detects the sand inlet position in real time, and the sand inlet position detection sensor (sand inlet position positioning device) detects the sand inlet in real time. The image visual recognition monitoring camera and the sand inlet position detection sensor are used to comprehensively detect whether they are aligned, thereby enhancing the adaptability and reliability of the alignment detection of the sand inlet and the sand outlet. When reversing, the main control system in the control room records the number of tank ports opened by the fracturing sand tank truck.

[0034] When the sand inlet position detection sensor does not detect the sand inlet of the fracturing sand tank truck, the alignment three-color integrated matrix indicator lights all light up in red; when it is detected that the sand outlet of the sand storage tank is about to align with the first sand inlet of the fracturing sand tank truck (the sand inlet near the rear of the vehicle is the first sand inlet), the alignment three-color integrated matrix indicator lights begin to partially light up in yellow, and a voice prompt is given: "The first tank port is detected, please continue to reverse". When aligned, the alignment three-color integrated matrix indicator lights all light up in green.

[0035] The on-site sand loading operation starts from the sand inlet N near the front of the vehicle. When in use, the driver will continue to be prompted by voice "Please continue to reverse". When it is detected that the sand outlet of the sand storage tank is about to align with the Nth sand inlet of the fracturing sand tanker, the three-color integrated matrix indicator light for alignment begins to partially light up yellow, and the voice prompt is: "The Nth tank opening is detected, please continue to reverse". When aligned, the three-color integrated matrix indicator lights for alignment all light up green. At this time, the voice prompt is: "Alignment is completed, please stop the car". If the alignment is not completed in the end due to slipping or reaction error, the system will voice prompt the driver to move forward or backward fine-tuning, and promptly voice prompt "Please stop the car, alignment is completed" until parking is completed.

[0036] The driver can understand the current position status of the vehicle by the color status of the three-color integrated matrix indicator light within the visible range.

[0037] When it is determined that the vehicle has stopped and the sand outlet is aligned with the sand inlet, the automatic gate mechanism automatically opens and voice broadcasts the sand loading process. The image visual recognition monitoring camera detects the material level in the fracturing sand tank truck in real time. When the material level is full or reaches the cumulative preset amount, the gate will automatically close. The voice broadcast device prompts the driver to change the port or leave.

[0038] The voice prompt "vehicle forward" is displayed. When the sand outlet of the sand storage tank is detected to be aligned with the sand inlet of the fracturing sand tanker, the three-color integrated matrix indicator light of the alignment begins to light up partially in yellow, and the voice prompt is: "The N-1 tank outlet is detected, please continue to move forward slowly". When aligned, the three-color integrated matrix indicator lights of the alignment light up green. The voice prompt "alignment completed, please stop the car" is displayed. If the car slips or an error is reflected, the vehicle position adjustment is prompted.

[0039] After all the sand inlets have completed the automatic sand loading operation, the three-color integrated matrix indicator lights will all light up green and flash, and the voice will announce: "Sand loading is complete, please leave";

[0040] When it is detected that the fracturing sand tanker has completely left the tank area, the control room system is reset and goes into sleep mode until the next sand tanker enters the detection area.

[0041] In one embodiment

[0042] It can also be implemented manually. The monitoring display screen in the control room shows the monitoring images of each tank port. At the same time, the system detects whether the fracturing sand tank truck has entered. If it is detected to be valid, the image visual recognition monitoring camera is turned on, and a voice prompt is given: "Please pay attention when reversing."

[0043] The staff communicates with the intercom system of the corresponding sand storage tank through a wireless intercom, and the intercom assists the driver in parking. After the parking is completed, the driver is informed to stop the car, and the monitoring video is used to feedback whether the parking result is valid. If not, the driver is informed through the intercom to make fine adjustments until the parking conditions are met.

[0044] The staff in the monitoring room opens or closes the sand gate through the control panel. The sand gate is opened manually and remotely, and the sand gate is closed manually and remotely after it is full through monitoring video feedback.

[0045] If there are other tank openings that need to be filled with sand, the monitoring personnel repeat the above operations. When the sand loading is completed, the staff in the monitoring room informs the driver through the intercom that the sand loading is completed.
