[0032] See also Figure 1 The utility model provides a connection mechanism for equipment rescue device, including: a connection seat 2, a main oil cylinder 3, an upper oil cylinder 5, a side oil cylinder 4 and a hydraulic pump. The connection seat 2 is used to connect with the rescue vehicle; the fixed end of the main oil cylinder 3 is rotatably connected with the connection seat 2, and a relatively sliding hoop is arranged in the middle of the fixed end of the main oil cylinder 3, and the telescopic end of the main oil cylinder 3 is used to connect with the equipment to be rescued; the fixed end of the upper oil cylinder 5 is used to be rotatably connected with the rescue vehicle, and the telescopic end of the upper oil cylinder 5 is rotatably connected with the hoop; the fixed end of the side oil cylinder 4 is rotatably connected with both ends of the connection seat 2, and the telescopic end of the side oil cylinder 4 is rotatably connected with the hoop; the hydraulic pump is respectively connected with the main oil cylinder 3, the upper oil cylinder 5 and the side oil cylinder 4; the hydraulic pump is used to provide power for the telescopic movement of the main oil cylinder 3, the upper oil cylinder 5 and the side oil cylinder 4. Among them, a through hole is arranged on the connection seat 2 to facilitate the connection with the rescue vehicle. The main oil cylinder 3, the upper oil cylinder 5, the side oil cylinder 4 and the hoop are all two, and are arranged relatively along the symmetry axis of the horizontal section of the connection seat 2. The fixed end of the upper oil cylinder 5 is provided with an upper oil cylinder seat 1 , and the fixed end of the upper oil cylinder 5 is rotatably connected to the rescue vehicle through the upper oil cylinder seat 1 .

[0033] Specifically, the through hole on the connecting seat 2 is connected to the rear hook of the rescue vehicle, and the hydraulic pump is started. The fixed end of the main cylinder 3 is subjected to the force generated by the telescopic end of the upper cylinder 5, and moves horizontally on the connecting seat 2; the fixed end of the main cylinder 3 is subjected to the force generated by the telescopic end of the side cylinder 4, thereby moving vertically on the connecting seat 2. Synchronously, the telescopic end of the main cylinder 3 is also telescoped and connected to the equipment to be rescued.

[0034] Furthermore, the connecting seat 2 includes a connecting seat body and a connecting block. A connecting block is provided in the middle section of one side of the connecting seat body adjacent to the main oil cylinder 3; the connecting block is rotatably connected to the fixed end of the main oil cylinder 3. The connecting seat 2 also includes two protrusions, which are correspondingly arranged at the two ends of the connecting seat body, and the protrusions are hinged to the fixed end of the side oil cylinder 4. Among them, the connecting block and the protrusion are both arranged on the side of the connecting seat body away from the end of the through hole, and a gap is left between the connecting block and the protrusion, in order to increase the rotation range of the fixed end of the main oil cylinder 3 on the connecting block and the rotation range of the fixed end of the side oil cylinder 4 on the protrusion.

[0035] In one of the embodiments, a connection mechanism for a rescue device also includes a fisheye joint 9 and a shackle 8, one end of the fisheye joint 9 is connected to the telescopic end of the main cylinder 3, and the other end of the fisheye joint 9 is rotatably connected to the shackle 8; the shackle 8 is used to connect with the equipment to be rescued. Among them, the fisheye joint 9 is easy to adapt to different installation positions and work requirements. When a rescue vehicle is transporting equipment to be rescued, such as a vehicle, the vehicle towed behind the rescue vehicle will inevitably vibrate continuously during the driving of the rescue vehicle. This vibration will be particularly obvious when the rescue vehicle is driving on a rough road. At this time, the fisheye joint 9 can absorb vibrations and impact loads, reduce the transmission to other components, and allow the shackle 8 to be more firmly connected to the horn hook of the vehicle.

[0036] Furthermore, a connection mechanism equipped with a rescue device further includes a side ear seat, which is arranged on the outer wall of the hoop and is hinged to the telescopic end of the side oil cylinder 4. Each hoop is provided with a side ear seat in the horizontal direction, and the two side ear seats are arranged in a direction away from each other.

[0037] Furthermore, a connection mechanism equipped with a rescue device also includes a hook and a hanging ring, wherein the hanging ring is arranged on the outer wall of the hoop; the hook is arranged at the telescopic end of the upper oil cylinder 5; and the hook can be hung on the hanging ring. Wherein, each hoop is provided with a hanging ring in the vertical direction, and the two hanging rings are arranged upward.

[0038] In one embodiment, a connection mechanism equipped with a rescue device further includes a multi-way solenoid valve 10, which is arranged on the pipeline connecting the hydraulic pump with the main oil cylinder 3, the upper oil cylinder 5 and the side oil cylinder 4. The multi-way solenoid valve 10 is used to control the pressure distribution and output of the hydraulic pump to the main oil cylinder 3, the upper oil cylinder 5 and the side oil cylinder 4. Among them, the pipeline connecting the hydraulic pump with the main oil cylinder 3, the upper oil cylinder 5 and the side oil cylinder 4 is a pipeline with a quick-connect plug, and the quick-connect connector facilitates the rapid installation and unloading of the pipeline. A pressure-maintaining valve can also be arranged on the main oil cylinder 3, the upper oil cylinder 5 and the side oil cylinder 4. By controlling the multi-way solenoid valve 10, the pressure distribution and output of the hydraulic pump to the main oil cylinder 3, the upper oil cylinder 5 and the side oil cylinder 4 are controlled, and then the pressure of the main oil cylinder 3, the upper oil cylinder 5 and the side oil cylinder 4 is maintained by the pressure-maintaining valve, and finally the towing operation is performed.

[0039] Furthermore, a connection mechanism for an equipment rescue device also includes a binocular camera 6 and an edge computing box 11. The binocular camera 6 is connected to the edge computing box 11, and is used to capture images of the equipment to be rescued, and send the images to the edge computing box 11. The edge computing box 11 is connected to the binocular camera 6, the multi-way solenoid valve 10, and the hydraulic pump, and is configured to: respond to the image, and according to the information of the equipment to be rescued contained in the image, issue an action instruction to the multi-way solenoid valve 10, so that the multi-way solenoid valve 10, in response to the action instruction, controls the hydraulic pump and the multi-way solenoid valve 10. Among them, sensors are set in the main cylinder 3, the upper cylinder 5 and the side cylinder 4. Preferably, a magnetostrictive displacement sensor is set in the main cylinder 3, the upper cylinder 5 and the side cylinder 4. The binocular camera 6 is set on the bracket 7, and the position of the bracket 7 can be placed as needed, preferably at the rear of the rescue vehicle.

[0040] Specifically, after the edge computing box 11 captures the target through the binocular camera, it combines the cylinder status feedback from the magnetostrictive displacement sensor and is calculated through the YOLOv5 target detection algorithm. If the posture needs to be adjusted, the edge computing box 11 uses an inverse operation to conclude that the magnetostrictive displacement sensor needs to move to the target position. The edge computing box 11 issues an action command, and the multi-way solenoid valve 10 receives the action command. The multi-way solenoid valve 10 controls the oil pipes in the main cylinder 3, the upper cylinder 5 and the side cylinder 4 to open and close, so that the main cylinder 3, the upper cylinder 5 and the side cylinder 4 can make corresponding extension or retraction actions. After the extension and retraction adjustment of the main cylinder 3, the upper cylinder 5 and the side cylinder 4, the shackle 8 is finally moved to the vicinity of the target.

[0041] It should be noted that the YOLOv5 target detection algorithm is an existing algorithm, and this application does not make any improvements to it.

[0042] Furthermore, a display screen is provided on the edge computing box 11, and the display screen is used to display images and working status information of the hydraulic pump. Among them, the display screen displays the target hook image and some related data information collected by the edge computing box 11 through the binocular camera.

[0043] Furthermore, a connection mechanism equipped with a rescue device also includes a controller, which is connected to the multi-way solenoid valve 10 by wire and / or wirelessly, and is used to control the main oil cylinder 3, the upper oil cylinder 5 and the side oil cylinder 4 through the multi-way solenoid valve 10, and receive the feedback signal of the multi-way solenoid valve 10. Among them, the display screen on the controller displays the current working mode and some working status information converted from the feedback signal of each oil cylinder.

[0044] It should be noted that pressure-maintaining valves are provided on the main cylinder 3 , the side cylinder 4 and the upper cylinder 5 to prevent damage to the main cylinder 3 , the side cylinder 4 and the upper cylinder 5 during towing operations.

[0045] Example

[0046] Stop the rescue vehicle in front of the equipment to be rescued, and the left and right position deviations, angle deviations, and up and down position deviations, angle deviations should not exceed the standard operating range. After the vehicle is parked, deploy the rescue equipment. Start the binocular camera 6 to collect image data of the posture and position of the equipment to be rescued, and transmit the image data to the edge computing box 11. The edge computing box 11 is calculated by the YOLOv5 target detection algorithm, combined with the cylinder status feedback from the magnetostrictive displacement sensor, and then the motion path required by each cylinder is obtained through inverse calculation, and a signal is sent to the hydraulic pump and the multi-way solenoid valve 10. After the hydraulic pump and the multi-way solenoid valve 10 receive the signal.

[0047] The upper cylinder 5, the side oil lever and the main cylinder 3 work simultaneously; the upper cylinder 5 begins to extend, and the main cylinder 3 is leveled from an oblique upward angle until it approaches the operating range. The side cylinder 4 begins to retract, and the main cylinder 3 is controlled to swing open and aim at the equipment to be rescued. The main cylinder 3 begins to extend until it approaches the bullhorn hook on the equipment to be rescued.

[0048] The binocular camera 6 monitors the position and posture of each cylinder in real time, and feeds back the monitored data to the display screen on the controller. At the same time, the displacement sensor inside the cylinder will feed back the operating status and real-time data of each cylinder to the display screen on the controller in real time.

[0049] When the main cylinder 3, the side cylinder 4 and the upper cylinder 5 are deployed in place, personnel inside the work vehicle judge the required manual operation direction through the image on the display screen of the controller fed back in real time by the binocular camera 6, and then fine-tune the posture of the towing and rescue equipment until the head shackle 8 of the main cylinder 3 is hung on the horn hook of the equipment to be rescued.

[0050] After the main oil cylinder 3 is hung on the horn hook, the towing and rescue operation begins. First, the oil circuit of the upper oil cylinder 5 is loosened to prevent the main oil cylinder 3 and the upper oil cylinder 5 from being damaged by the up and down bumps during the towing operation. The side oil cylinder 4 uses the pressure-maintaining valve to lock the oil circuit and maintain pressure, so that the towing and rescue equipment can maintain a left-right balanced posture as much as possible. Similarly, the oil circuit of the main oil cylinder 3 is also locked by the pressure-maintaining valve. The pressure-maintaining valves on each oil cylinder prevent the oil pressure in the oil circuit of each oil cylinder from being damaged due to different force directions during the towing operation.

[0051] During the towing and rescue process, the binocular camera 6 will continue to work to monitor the mission posture. If there are various unexpected and sudden situations such as hook disengagement, cylinder pressure maintenance failure, large posture changes, cylinder damage, etc. during the operation, the staff can understand them in time by observing the display screen.

[0052] When the rescue vehicle towing task is completed, the operator releases the shackle 8. The main cylinder 3 contracts until the displacement sensor built into the cylinder is in place, and at the same time, the side cylinder 4 is pushed out until it reaches the preset position of the retracted state of the side cylinder 4. At the same time, the upper cylinder 5 contracts until it reaches the preset position of the retracted state of the upper cylinder 5.

[0053] In the above embodiments, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0054] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time.
