[0032] The present application provides an accessory identification device and also provides an engineering machine including the accessory identification device.
[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0034] like Figure 1-2 , an accessory identification device, used for identifying accessories 4 of engineering machinery. The accessory identification device includes an identification structure 1 and a structure to be identified 2. A construction machinery is equipped with various types of accessories 4 according to different working scenarios, including but not limited to forks, buckets, digging buckets, booms, breaker hammers, etc. The identification structure 1 is arranged on the accessory mounting part 3 of the construction machinery. The structure to be identified 2 is arranged on the accessories 4 of the construction machinery, and the appearance of the structure to be identified 2 arranged on different types of accessories 4 is different. When the accessory 4 is installed on the accessory mounting part 3, the identification structure 1 can identify the appearance of the structure to be identified 2 on the above-mentioned accessory 4, and then determine the type of the accessory 4 installed on the accessory mounting part 3.
[0035] It should be noted that "the appearance of the structure to be identified 2 is different" means that the structure to be identified 2 has different appearance attributes that can be identified; the appearance attributes that can be identified include but are not limited to at least one of the formed pattern, size, shape, and color.
[0036] The application scenarios of construction machinery are very wide, covering many fields such as construction, water conservancy, electricity, roads, mines, ports, etc., such as loading and unloading in the field, stacking on farms, etc.; different application scenarios require the use of different types of accessories, such as forks, buckets, digging buckets, booms, breakers, etc. Different types of accessories have different operating requirements and restrictions. For example, some accessories may require specific operating speeds or lifting heights to be used safely. The accessory identification device of the present application can identify the type of accessory 4 installed on the accessory mounting part 3, so that the construction machinery can automatically adjust its operating parameters according to the identified type of accessory 4, ensuring that the construction machinery works in accordance with the correct operating procedures, realizing automated control, and reducing the risk of accidents.
[0037] Furthermore, the appearance of the structure to be identified 2 is a physical property, which will not be affected by external environmental factors and can be accurately identified by the identification structure 1 under any conditions, thus solving the problem that the attachment 4 cannot be identified.
[0038] In certain embodiments of the present application, the structure to be identified 2 includes a plurality of pieces to be identified 21 , and the number and / or arrangement positions of the pieces to be identified 21 of different structures to be identified 2 are different, so that the appearances of different structures to be identified 2 are different.
[0039] It should be noted that "different structures 2 to be identified have different numbers and / or locations of the pieces 21 to be identified", that is, when different structures 2 to be identified are respectively arranged on different types of attachments 4, the numbers and / or locations of the pieces 21 to be identified on different types of attachments 4 are different. "Different structures 2 to be identified have different appearances", that is, the arrangement patterns of the pieces 21 to be identified with different numbers and / or different locations are different.
[0040] Preferably, different arrangement patterns are obtained by combining the number and position of the to-be-identified parts 21 , each arrangement pattern corresponds to a specific type of to-be-identified structure 2 , and a specific type of to-be-identified structure 2 corresponds to a specific type of attachment 4 .
[0041] As described above, the structure of the structure to be identified 2 is simple, and by setting the to-be-identified parts 21 in different numbers and positions, various types of arrangement patterns can be obtained, thereby identifying various types of accessories 4, so as to achieve accurate distinction between the various accessories 4 and facilitate accurate identification of the accessories 4.
[0042] In some embodiments, there are n locations where the to-be-identified parts 21 of the to-be-identified structure 2 are arranged, and the number of such locations is m.
[0043] When 0≤m≤n, the number of different structures 2 to be identified is 2 n For example: the to-be-identified part 21 of the to-be-identified structure 2 includes 3 setting positions, and the number of the to-be-identified parts 21 is 0-3; at this time, ① when the number of the to-be-identified parts 21 is 0, that is, when the to-be-identified parts 21 are not set in the three setting positions, it corresponds to 1 type of structure 2 to be identified; ② when the number of the to-be-identified parts 21 is 1, that is, when the to-be-identified part 21 is set in any one of the three setting positions, it corresponds to C(3,1)=3 types of structures 2 to be identified; ③ when the number of the to-be-identified parts 21 is 2, that is, when the to-be-identified parts 21 are set in any two of the three setting positions, it corresponds to C(3,2)=3 types of structures 2 to be identified; ④ when the number of the to-be-identified parts 21 is 3, that is, when the to-be-identified parts 21 are set in all three setting positions, it corresponds to C(3,3)=1 type of structure 2 to be identified; in summary, a total of 1+C(3,1)+C(3,2)+C(3,3)=2 is obtained. 3 = 8 types of structures to be identified2.
[0044] When 0<m≤n, the number of different structures 2 to be identified is 2 n -1. For example: the to-be-identified part 21 of the to-be-identified structure 2 includes 3 setting positions, and the number of the to-be-identified parts 21 is 1-3; at this time, ① when the number of the to-be-identified part 21 is 1, that is, when the to-be-identified part 21 is set in any one of the three setting positions, there are C(3,1)=3 types of structures 2 to be identified; ② when the number of the to-be-identified parts 21 is 2, that is, when the to-be-identified part 21 is set in any two of the three setting positions, there are C(3,2)=3 types of structures 2 to be identified; ③ when the number of the to-be-identified parts 21 is 3, that is, when the to-be-identified parts 21 are set in all three setting positions, there is C(3,3)=1 type of structures 2 to be identified; in summary, a total of C(3,1)+C(3,2)+C(3,3)=2 3 -1=7 types of structures to be identified 2.
[0045] It should be further explained that when it is determined that the types of accessories 4 to be identified are less than 7 or more, the types of structures 2 to be identified are less than 7 or more, so the number of setting positions of the parts 21 to be identified of the structures 2 to be identified can be appropriately reduced or increased.
[0046] In some embodiments of the present application, the identification structure 1 includes n identification elements 11. When the attachment 4 is mounted on the attachment mounting member 3, the n identification elements 11 correspond one-to-one to the n setting positions of the structure to be identified 2.
[0047] As described above, no matter how many to-be-identified elements 21 are arranged in the to-be-identified structure 2, and at which positions each to-be-identified element 21 is arranged, they can all be identified by the identification element 11 in the identification structure 1. The above identification structure 1 has a simple structure and can quickly and accurately identify to-be-identified structures 2 of various arrangement patterns.
[0048] In some embodiments, in addition to being configured as a structure of n identification members 11 corresponding one-to-one to the n setting positions of the structure to be identified 2, the identification structure 1 may also be configured as other structures; for example, the identification structure 1 is an image acquisition module, which can acquire the arrangement pattern formed by the structure to be identified 2, and then determine the type of the structure to be identified 2, and then determine the type of the attachment 4 that sets the structure to be identified 2. Furthermore, the image acquisition module includes a camera, which acquires the arrangement pattern formed by the structure to be identified 2.
[0049] In some embodiments of the present application, the to-be-identified member 21 is arc-shaped. When the attachment 4 rotates around the first rotation axis 5 relative to the attachment mounting member 3, the to-be-identified member 21 also rotates around the first rotation axis 5. The center of the arc-shaped to-be-identified member 21 is the same as the center of the to-be-identified member 21 rotating around the first rotation axis 5.
[0050] Furthermore, the center angle of the to-be-identified member 21 is not less than the center angle of the to-be-identified member 21 rotating around the first rotation axis 5 .
[0051] As described above, it can be ensured that within the entire working rotation range of the accessory 4, the part to be identified 21 includes an identification point relative to the position of the identification structure 1, so that the identified structure 1 can be accurately identified; this avoids the problem that after the accessory 4 rotates relative to the accessory mounting part 3, the part to be identified 21 and the identification structure 1 are not aligned correctly, resulting in the inability to be identified.
[0052] In certain embodiments of the present application, the identification element 11 is a proximity switch; and the element to be identified 21 is a sensor strip.
[0053] As mentioned above, the accessory identification device has a simple structure and is easy to install; the proximity switch can detect the presence of the sensor strip without contacting it, reducing mechanical wear and improving reliability; it has a fast response speed, strong environmental adaptability, and a long service life, effectively avoiding the risk of failure of the accessory identification device.
[0054] In some embodiments of the present application, the proximity switch is an inductive proximity switch, and the sensing strip is a metal strip.
[0055] Inductive proximity switches are a low-cost way to detect metal objects without contact. When the inductive proximity switch approaches or moves away from the metal bar, the sensing signal of the inductive proximity switch will automatically change, thereby achieving the purpose of detecting whether the metal bar exists.
[0056] In some embodiments, the proximity switch and the sensing strip may be configured in other forms besides being configured as a combination of an inductive proximity switch and a metal strip; for example, the proximity switch may be a capacitive proximity switch, and the sensing strip may be a metal strip or a non-metal strip; or, the proximity switch may be an electromagnetic proximity switch, and the sensing strip may be a magnetic strip.
[0057] In summary, the present application further provides an engineering machine, which includes an attachment mounting part 3, an attachment 4, and an attachment identification device as described above. The engineering machine includes multiple types of attachments 4, and the attachment identification devices of different types of attachments 4 have different structures 2 to be identified.
[0058] It should be noted that the accessory mounting part 3 is an arm bracket.
[0059] Since the engineering machinery of the present application includes the accessory identification device described above, the beneficial effects brought about by the accessory identification device on the engineering machinery can be found above and will not be described in detail here.
[0060] In some embodiments of the present application, the accessory mounting member 3 includes a first hinged portion 31. The accessory 4 includes a second hinged portion 41. The first rotating shaft 5 passes through the first hinged portion 31 and the second hinged portion 41 in sequence to achieve rotatable installation of the accessory 4 on the accessory mounting member 3. The identification structure 1 of the accessory identification device is connected to the first hinged portion 31, and the identification structure 1 extends to a position corresponding to the structure to be identified 2 of the accessory identification device.
[0061] It should be noted that the attachment 4 includes a first mounting surface 42, and the second hinged portion 41 is two connecting ear plates arranged at intervals, and the connecting ear plates are arranged perpendicularly to the first mounting surface 42. A mounting plate 43 is arranged on the first mounting surface 42, and the mounting plate 43 is located between the two connecting ear plates and is parallel to the connecting ear plates; a plurality of arc-shaped parts to be identified 21 are arranged at intervals on the mounting plate 43, and a plurality of arc-shaped parts to be identified 21 are arranged cocentrically, and the center of the circle is located on the first rotating shaft 5. The first hinged portion 31 includes two connecting portions arranged at intervals, and the two connecting portions are located between the two second hinged portions 41, and the mounting plate 43 is located between the two connecting portions; the identification structure 1 includes a strip-shaped extension member 12, and the extension member 12 is arranged to extend radially along the plurality of arc-shaped parts to be identified 21, and has an intersection with each part to be identified 21, and an identification member 11 is arranged at each intersection of the extension member 12.
[0062] As described above, the detachable installation of the accessory 4 on the arm is achieved, and the accessory 4 can rotate around the first rotation axis 5 relative to the arm; and the installation of the part to be identified 21 on the accessory 4 and the installation of the identification part 11 on the arm are achieved, and within the entire working rotation range of the accessory 4, the part to be identified 21 includes an identification point relative to the position of the identification structure 1, and is thereby accurately identified by the identification structure 1.
