Description

Technical Field

[0001] The present invention relates to the technical field of engineering machinery, and in particular to a full-automatic quick-change device for emergency rescue engineering equipment and a use method thereof. Background Art

[0002] Emergency rescue engineering equipment plays a vital role in responding to emergencies and disasters. Natural disasters occur frequently in my country. After a disaster occurs, the biggest role of emergency rescue equipment is to complete various complex rescue tasks in the shortest time and reduce the property losses of the affected people. Emergency rescue equipment must have the characteristics and functions of multi-function, high efficiency, and prevention of secondary personnel injury in order to adapt to the operation requirements in complex environments and save people's lives and property. However, at present, when disasters occur, rescue tasks are mainly completed by engineering machinery or rescue equipment equipped with engineering machinery working arms. Due to the limitations of their own working attributes, the working arms of rescue equipment often have single functions, poor interchangeability of working tools, slow assembly and disassembly speed (required time>30min), which does not meet the requirements of the rescue site. At the same time, existing devices are often inconvenient to operate and require a lot of time and manpower, resulting in low rescue efficiency. In addition, considering the complex situation at the rescue site, poor road traffic conditions, small rescue space, and frequent exchanges of personnel and materials, multiple rescue vehicles are not allowed to enter the site for operation at the same time. Otherwise, not only will all functions fail to be exerted, but the working arms may interfere with each other, and the chaos on the site will reduce the rescue efficiency.

[0003] Existing devices, such as a hydraulic automatic quick-switching docking platform provided by publication number CN 109555177 B, include an active docking module, a passive docking module and a hydraulic docking module. The active docking module is installed at the end of the working arm of the rescue equipment, and the passive docking module is fixed on the working attachment. The hydraulic docking module, as a hydraulic connection component with a unified interface, can realize the connection of the oil circuit between the active and passive docking modules. By replacing different working attachments with the passive docking module, a multifunctional operation of the working arm can be realized; but since the application requires operating the working arm to make the active docking module snap onto the passive docking module for preliminary positioning, the operation steps are relatively delicate and require high standards of the operator, which makes the use of the device cumbersome, reduces the disassembly and assembly efficiency, and thus affects the rescue efficiency. Summary of the invention

It should be noted that the number of each individual slide groove and the angle locking hole 1012 of the guide slide groove 1011 can be the same as the number of the second piston rods 404, that is, three, or twice the number of the second piston rods 404, that is, six. In some embodiments, a freely rotatable ball structure may be provided at the bottom of the second piston rod 404 so that the second piston rod 404 can slide more smoothly in the guide groove 1011 at the top of the fixed plate 101 on the main connecting member, thereby improving the efficiency of angle locking.

At this time, operate the emergency rescue engineering equipment to push the main connecting member 1, so that the connecting column 201 of the secondary connecting member 2 is inserted into the connecting sleeve 301; S3. When the connecting column 201 is inserted into the connecting sleeve 301 and pushes the first piston rod 402, the oil in the locking hydraulic chamber 401 pushes the second piston rod 404 to slide along the guide groove 4011 and drives the angle locking hydraulic chamber 401 to rotate. When the second piston rod 404 slides and is inserted into the angle locking hole 1012, a bolt is screwed into the fixing bolt hole 405 to relatively fix the angle between the connecting sleeve 301 and the locking hydraulic chamber 401. At this time, the clamping rod 203 on the auxiliary connecting member 2 is clamped into the clamping seat 406 on the main connecting member 1, so that the main connecting member 1 and the auxiliary connecting member 2 are automatically fixed, that is, the connection between the emergency rescue engineering equipment and the operating tool is completed. S4. When the working tool needs to be replaced, oil is filled into the unloading hydraulic chamber 408 through the unloading oil inlet 4081, pushing the piston top block 409 downward, and pushing the clamping seat 406 open, and pushing the clamping rod 203 out of the clamping seat 406, so that the auxiliary connecting member 2 is separated from the main connecting member 1 to replace other types of working tools.

[0032] In S3, when the main connecting member 1 and the auxiliary connecting member 2 are fixed, the hydraulic connecting pipe 502 located on the clamping rod 203 can be connected with the oil input pipe 501 at the bottom of the main connecting member 1. At this time, the solenoid valve 5011 at the oil input pipe 501 is opened, and the hydraulic oil can be input into the liquid storage pan 503 through the oil input pipe 501 and the hydraulic connecting pipe 502, and the hydraulic oil is input into the working tool through the oil delivery port 501 on the liquid storage pan 503 to drive the working tool to perform emergency rescue engineering operations.

[0033] Practical application cases Before emergency rescue, the main connecting member 1 is first fixed to the emergency rescue equipment, and the plurality of auxiliary connecting members 2 are fixed to different types of working tools, so that different types of working tools can be quickly switched during emergency rescue; When arriving at the emergency rescue site, operate the emergency rescue equipment to drive the main connecting member 1 close to the auxiliary connecting member 2 on the working tool. Under normal circumstances, the working tool is placed on a horizontal surface such as the ground. When the connecting sleeve 301 of the main connecting member 1 is close to the connecting column 201 of the auxiliary connecting member 2, due to the action of the magnet 6, the connecting sleeve 301 rotates and quickly adjusts to the installation angle matching with the connecting column 201. At this time, continue to push the main connecting member 1 to insert the connecting column 201 into the connecting sleeve 301, and push the first piston rod 402 to trigger the angle locking. At this time, use bolts to fix the connecting sleeve 301 and the locking hydraulic chamber 401 to lock the device at an angle; When the connecting column 201 is inserted into the connecting sleeve 301, the clamping rod 203 at the bottom is simultaneously clamped into the clamping seat 406, so that the main connecting member 1 and the auxiliary connecting member 2 are fixed, that is, the emergency rescue equipment and the working tool are fixed. At this time, the oil input pipe 501 is connected with the hydraulic connecting pipe 502, and the solenoid valve 5011 is opened to input the hydraulic oil in the emergency rescue equipment into the working tool to drive the working tool; When it is necessary to replace other types of working tools, oil is filled into the unloading hydraulic chamber 408, pushing the piston top block 409 downward, pushing the clamping seat 406 open and pushing the clamping rod 203 downward to separate the main connecting part 1 from the auxiliary connecting part 2, that is, the emergency rescue equipment and the working tool are quickly separated. At this time, other types of working tools can be replaced in the same way as above.
