Description

Technical Field

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

[0002] Emergency rescue engineering equipment plays a vital role in responding to emergencies and disasters. Natural disasters are frequent in my country. After a disaster, the primary role of emergency rescue equipment is to complete complex rescue tasks in the shortest possible time and minimize property losses. Emergency rescue equipment must be multifunctional, efficient, and prevent secondary injuries to adapt to the demands of complex environments and save lives and property. However, currently, rescue operations are primarily carried out by engineering machinery or rescue equipment equipped with an engineering machinery working arm. Limited by their inherent operational characteristics, the working arms of rescue equipment often have limited functionality, poor tool interchangeability, and slow assembly and disassembly (requiring >30 minutes), making them unsuitable for on-site rescue operations. Furthermore, existing equipment is often inconvenient to operate, requiring significant time and manpower, resulting in low rescue efficiency. Furthermore, given the complexities of rescue sites, poor road conditions, confined rescue spaces, and the frequent movement of personnel and supplies, multiple rescue vehicles are prohibited from operating simultaneously. This would not only prevent the full functionality of the rescue equipment, but also potentially cause interference between the working arms, leading to chaos and reduced 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; however, 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 operator skills, which makes the use of the device cumbersome, reduces the disassembly and assembly efficiency, and thus affects the rescue efficiency. Summary of the Invention

[0004] In response to the above-mentioned problems, the present invention aims to provide a fully automatic quick-change device and a method of use for emergency rescue engineering equipment.

By designing an automatic locking component, the main connecting part and the auxiliary connecting part are angularly locked by hydraulic action and a piston structure, and the auxiliary connecting part and the main connecting part are locked through a clamping seat. By designing an oil connecting component, the main connecting part and the auxiliary connecting part are fluidically connected after being locked with each other to transport hydraulic oil for driving the working tool.

[0010] Based on the above technical solution, further, a plurality of paired clamping seats are elastically arranged at the bottom of the main connecting member, and a plurality of clamping rods that can be clamped in the middle of the clamping seat are provided on the secondary connecting member.

[0019] Based on the above scheme, further, in S3, when the main connecting member and the auxiliary connecting member are fixed, the hydraulic connecting pipe located on the clamping rod can be connected to the oil input pipe at the bottom of the main connecting member. At this time, the solenoid valve at the oil input pipe is opened, and the hydraulic oil can be input into the liquid storage pan through the oil input pipe and the hydraulic connecting pipe, and the hydraulic oil is input into the working tool through the oil delivery port on the liquid storage pan to drive the working tool to perform emergency rescue engineering operations.

[0020] The beneficial effects of the present invention are:

[0021] 1. By designing an automatic alignment component, the angles between the main connecting part connecting the emergency rescue engineering equipment and the auxiliary connecting part connecting the working tool are automatically aligned during installation. By designing an automatic locking component, the rotation angle is automatically locked when the auxiliary connecting part is installed to the main connecting part, and the two are automatically fixed relative to each other, without spending a lot of time on installing the working tool.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0040] The inventors have found that 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 properties, the working arms of rescue equipment often have single functions, poor interchangeability of working tools, slow assembly and disassembly speeds, and do 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 also interfere with each other, causing chaos on the site and reducing rescue efficiency. The existing quick-switching devices have high requirements for operators due to the high precision required for operation, which makes the use of the device cumbersome, reduces the efficiency of disassembly and assembly, and thus affects the rescue efficiency. It is not suitable for emergency rescue projects.

[0041] Based on the above findings, the present application proposes a fully automatic quick-change device and a method of use for emergency rescue engineering equipment. By designing an automatic alignment component, a connecting sleeve is rotatably set in the main connecting part, and multiple magnets with different magnetic properties are set on the connecting sleeve and the connecting column on the auxiliary connecting part. When the main connecting part approaches the auxiliary connecting part, the connecting sleeve is rotated and automatically aligned with the connecting column of the auxiliary connecting part; by designing an automatic locking component, the connecting column of the auxiliary connecting part is inserted into the connecting sleeve, and the hydraulic chamber at the top of the main connecting part is squeezed, and the piston rod is pushed into the angle locking hole on the main connecting part through the angle locking hydraulic chamber to perform angle locking, and the clamping rod on the auxiliary connecting part is clamped through the clamping seat at the bottom of the main connecting part to lock the main connecting part and lock the auxiliary connecting part; by designing an oil connecting component, an oil input pipe that can be connected with the auxiliary connecting part is set on the main connecting part, and the oil is input into the hydraulic disk on the auxiliary connecting part to provide hydraulic oil to the working tool. It has the advantages of easy operation, stable connection, high disassembly and replacement efficiency, comprehensive functions and simple structure.

[0042] See Figure 1-Figure 7 The present application discloses a fully automatic quick-change device for emergency rescue engineering equipment, comprising a main connecting member 1 for connecting the emergency rescue engineering equipment and a secondary connecting member 2 for connecting the working tool, see Figure 8 as well as Figure 9 In some embodiments, the main connector 1 and the secondary connector 2 are made of a metal material with high strength and strong corrosion resistance. The main connector 1 includes a transversely arranged main connector upper fixing plate 101 and a main connector lower fixing plate 102. Both are pancake-shaped structures with a through hole in the middle, and the two are connected by a hollow cylindrical connecting tube 103. The secondary connector 2 includes a secondary connector fixing plate 202. A connecting column 201 is vertically fixed to the middle of the secondary connector fixing plate 202 by welding or integral molding.

The automatic alignment component 3 includes a connecting sleeve 301 rotatably arranged in the middle of the main connector 1. The connecting sleeve 301 is a hollow cylindrical structure as a whole. A plurality of bearings 303 that can be tightly fitted with the inside of the connecting cylinder 103 of the main connector 1 are sleeved on the connecting sleeve 301. A sealing ring 302 is also provided at the connection between the bottom of the main connector 1 and the bottom of the connecting sleeve 301 to fill the gap between the main connector 1 and the connecting sleeve 301 to prevent the entry of dust and other impurities.

[0044] See Figure 10 , a plurality of magnets 6 are evenly distributed on the inner end surface of the bottom of the connecting sleeve 301 and the top of the connecting column 201. Specifically, the cross-sectional shape of the inner end surface of the connecting sleeve 301 and the entire connecting column 201 are both polygonal shapes with edges and corners. In an embodiment provided by the present invention, the inner end surface of the connecting sleeve 301 and the cross-sectional shape of the connecting column 201 are both regular hexagonal shapes that fit closely with each other. The inner end surface of the bottom of the connecting sleeve 301 and the top of the connecting column 201 are both provided with a plurality of grooves for fixing the magnets 6. The number of grooves of the two is equal, and the magnetic properties of each adjacent magnet 6 are different;

[0045] When the connecting sleeve 301 is close to the connecting column 201, the attraction and repulsion between the magnets 6 can rotate the connecting sleeve 301, and automatically align the connecting column 201 of the auxiliary connecting part 2 with the connecting sleeve 301, so as to facilitate the insertion of the auxiliary connecting part 2 into the connecting sleeve 301, thereby automatically aligning the main connecting part 1 and the auxiliary connecting part 2, and then facilitating the connection of the working tool connected to the auxiliary connecting part 2 with the emergency rescue engineering equipment connected to the main connecting part 1, thereby improving the connection efficiency and the efficiency of switching working tools.

[0046] The main connecting member 1 is provided with an automatic locking assembly 4 for fixing the auxiliary connecting member 2. The automatic locking assembly 4 includes an angle locking hydraulic chamber 401 which is rotatably arranged on the top of the main connecting member 1. Figure 11 , a first piston rod 402 that can be contacted and pushed by the top of the connecting column 201 is elastically provided in the middle of the angle locking hydraulic chamber 401. Specifically, a hollow cylindrical slide groove connected to the interior of the angle locking hydraulic chamber 401 is provided at the center of the bottom thereof, and the first piston rod 402 is slidably provided in the slide groove.

[0047] A plurality of second piston rods 404 are elastically slidably provided at the bottom of the angle locking hydraulic chamber 401 along the circumference.

It should be noted that a limiting nut 411 for limiting the second piston rod 404 is installed at the bottom of the slide groove by a threaded connection, and a second piston rod return spring 410 is fixed below the top of the second piston rod 404. When the first piston rod 402 is pushed upward, it can squeeze the oil inside the angle locking hydraulic chamber 401, and synchronously push the three second piston rods 404 downward, squeezing the second piston rod return spring 410.

[0048] The top of the main connecting member 1, specifically, the top of the fixing plate 101 of the main connecting member, is provided with a guide slot 1011. The guide slot 1011 is evenly distributed with a plurality of angle locking holes 1012 that cooperate with the second piston rod 404.

When the first piston rod 402 moves upward and pushes the multiple second piston rods 404 downward, the second piston rods 404 can slide along the guide slide groove 1011 and rotate the angle locking hydraulic chamber 401 relative to the main connecting member 1 until the bottom of the second piston rod 404 is inserted into the angle locking hole 1012 in the guide slide groove 1011. It should be noted that the number of each individual slide groove and 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.

[0050] 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.

[0051] On the angle locking hydraulic chamber 401, specifically, on the bottom of the angle locking hydraulic chamber 401, a plurality of fixing bolt holes 405 for fixing the connecting sleeve 301 are provided on the side wall of the hollow cylindrical slide groove for installing the first piston rod 402; when the second piston rod 404 slides and is inserted into the angle locking hole 1012, bolts are screwed into the fixing bolt holes 405 to fix the connecting sleeve 301 and the angle locking hydraulic chamber 401 relatively.

The auxiliary connecting member 2 is provided with a plurality of card rods 203 that can be connected to the middle part of the card seat 406, specifically, located on the connecting column 201. A clamping rod 203 is fixed to each end surface of one end of the auxiliary connector fixing plate 202 by welding or other means. The top of the clamping rod 203 and the bottom of the clamping seat 406 are both provided with inclined surfaces. When the clamping rod 203 approaches the clamping seat 406, it is convenient for the clamping rod 203 to be pushed into the middle of the two clamping seats 406, thereby pushing the two clamping seats 406 to the sides. When the clamping rod 203 completely slides into the area formed between the two clamping seats 406, the clamping seat 406 is reset under the action of the clamping seat reset spring 407, and the clamping rod 203 is locked.

[0053] The main connecting member 1 is fixed with an unloading hydraulic chamber 408 near the bottom, and the bottom of the unloading hydraulic chamber 408 is slidingly provided with multiple piston top blocks 409 that penetrate the bottom of the main connecting member 1 and face the middle of the clamping seat 406. The unloading hydraulic chamber 408 is provided with an unloading oil inlet 4081; when it is necessary to remove the clamping seat 406 from fixing the clamping rod 203, oil is filled into the unloading hydraulic chamber 408 through the unloading oil inlet 4081, and the piston top block 409 is pushed downward. The piston top block 409 is provided with an inclined surface that matches the top of the clamping seat 406, which can push the two clamping seats 406 to both sides. , and push the clamping rod 203 downward to disengage the auxiliary connector 2 from the main connector 1, thereby disengaging the working tool connected to the auxiliary connector 2 from the emergency rescue engineering equipment connected to the main connector 1, so as to quickly switch the working tools; it should be noted that the number of each paired clamping seat 406 and piston top block 409 should remain equal, and can be less than the number of clamping rods 203. In the optimal case, the number of clamping rods 203 is twice that of the clamping seat 406 and the piston top block 409, and the clamping seat 406 and the piston top block 409 should be evenly distributed in a circle with the center of the main connector 1 as the center.

Operate the emergency rescue engineering equipment to drive the main connecting member 1, and move the connecting sleeve 301 in the middle of the main connecting member 1 closer to the connecting post 201 on the secondary connecting member 2. When the connecting sleeve 301 and the connecting post 201 are close to each other, the connecting sleeve 301 is rotated by the action of the magnet 6, and the angle between the connecting sleeve 301 and the connecting post 201 is automatically adjusted. At this time, operate the emergency rescue engineering equipment to push the main connecting member 1, so that the connecting post 201 of the secondary connecting member 2 is inserted into the connecting sleeve 301;

[0060] 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 secondary 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 secondary connecting member 2 are automatically fixed, that is, the connection between the emergency rescue engineering equipment and the working tool is completed;

[0061] 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, pushing the clamping rod 203 out of the clamping seat 406, thereby disengaging the auxiliary connecting member 2 from the main connecting member 1 to replace other types of working tools.

[0062] 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 to 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.

[0063] Practical application cases

[0064] Before emergency rescue, the main connecting member 1 is fixed to the emergency rescue equipment, and the multiple 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;

[0065] When arriving at the emergency rescue site, operate the emergency rescue equipment to drive the main connecting member 1 close to the secondary connecting member 2 on the working tool. Under normal circumstances, the working tool is placed on a horizontal surface such as the ground. Then, when the connecting sleeve 301 of the main connecting member 1 is close to the connecting column 201 of the secondary connecting member 2, due to the action of the magnet 6, the connecting sleeve 301 rotates and quickly adjusts to the installation angle that matches 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 lock. At this time, use bolts to fix the connecting sleeve 301 and the locking hydraulic chamber 401 to lock the device at an angle.

[0066] 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, thereby fixing the main connecting member 1 and the auxiliary connecting member 2, that is, fixing the emergency rescue equipment and the working tool. At this time, the oil input pipe 501 is connected to 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;

[0067] 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.
