Description

Technical Field

[0001] This utility model relates to the field of excavator equipment technology, and in particular to a counterweight structure and an excavator. Background Technology

[0002] Currently, by configuring a counterweight structure, excavators can adjust their own weight and the weight of their connected parts to appropriate positions during construction, thereby ensuring the safety and operational stability of the excavator during construction.

[0003] In practical applications, the counterweight structure only has reinforcing ribs on the surrounding plates. During filler filling, as the amount of filler increases, it continuously compresses the bottom plates and protective covers of the counterweight structure, resulting in a bottom-heavy, top-light structure. However, since the reinforcing ribs are only located on the surrounding plates, the protective cover is easily deformed under the pressure of the filler, leading to a decrease in flatness. Furthermore, the thermal expansion and contraction of the filler further increases the risk of deformation. Therefore, reducing the risk of deformation of the protective cover in the counterweight structure to improve its reliability has become an urgent problem to be solved. Utility Model Content

[0039] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0040] Currently, by configuring a counterweight structure, excavators can adjust their own weight and the weight of their connected parts to appropriate positions during construction, thereby ensuring the safety and operational stability of the excavator during construction.

[0041] In practical applications, the counterweight structure only has reinforcing ribs on the surrounding plates. During filler filling, as the amount of filler increases, it continuously compresses the bottom plates and protective covers of the counterweight structure, resulting in a bottom-heavy, top-light structure. However, since the reinforcing ribs are only located on the surrounding plates, the protective cover is easily deformed under the pressure of the filler, leading to a decrease in flatness. Furthermore, the thermal expansion and contraction of the filler further increases the risk of deformation. Therefore, reducing the risk of deformation of the protective cover in the counterweight structure to improve its reliability has become an urgent problem to be solved.

[0042] In response, this utility model discloses a counterweight structure and an excavator, which can reduce the risk of deformation of the counterweight structure's protective cover, thereby improving the reliability of the counterweight structure.

[0043] like Figure 1 and Figure 2As shown, this utility model discloses a counterweight structure, which includes: a surrounding plate 100, a protective cover 200, a support member 300, and a cavity reinforcement member 400. The surrounding plate 100 has a top plate 110, a side plate 120, and a bottom plate 130, which are connected sequentially, with the top plate 110 and the bottom plate 130 arranged parallel to each other. The protective cover 200 is connected to the top plate 110, the side plate 120, and the bottom plate 130 respectively, so that the protective cover 200, the top plate 110, the side plate 120, and the bottom plate 130 enclose a filling cavity, which is used to accommodate counterweight filler added from the outside. The support member... The support member 300 is disposed in the packing cavity. The edge of the support member 300 is connected to the cover 200, the top plate 110, the side plate 120 and the bottom plate 130 respectively, so as to divide the packing cavity into multiple sub-cavities. The cavity reinforcement member 400 is disposed in each sub-cavity of the packing cavity. The edge of the cavity reinforcement member 400 is connected to the surrounding plate 100, the cover 200 and the support member 300 respectively. The cavity reinforcement member 400 is arranged parallel to the top plate 110 and the bottom plate 130 respectively.

[0044] In this embodiment, refer to Figure 1 The enclosure body 100 consists of three parts: a top plate 110, a side plate 120, and a bottom plate 130. The top plate 110 is located at the upper end of the counterweight structure, the bottom plate 130 is located at the lower end of the counterweight structure, and the side plate 120 is located at the rear end of the counterweight structure. The top plate 110 and the bottom plate 130 are arranged parallel to each other. The rear edge of the top plate 110 connects to the top edge of the side plate 120, and the lower edge of the side plate 120 connects to the rear edge of the bottom plate 130. (Refer to...) Figure 2 The protective cover 200 covers the front end and left and right sides of the counterweight structure, thereby closing the open portions on the front and left and right sides of the enclosure 100. This allows the protective cover 200, top plate 110, side plates 120, and bottom plate 130 to enclose and form an internal filling cavity. The filling cavity can accommodate counterweight filler added from the outside. The counterweight filler is mainly composed of cement, barite, water, etc., and some filler may also contain pig iron.

[0045] A support member 300 is provided inside the packing cavity. Each edge of the support member 300 is connected to the protective cover 200, top plate 110, side plate 120, and bottom plate 130, thereby dividing the packing cavity into several sub-cavities in the left-right direction. Cavity reinforcement members 400 are disposed within each sub-cavity of the packing cavity, and are arranged laterally parallel to the top plate 110 and bottom plate 130. When counterweight packing is filled into the packing cavity, the cavity reinforcement members 400 can divert the counterweight packing, causing it to stratify and preventing it from accumulating entirely at the bottom of the packing cavity. This reduces pressure on the bottom of the surrounding plate 100 and the protective cover 200, minimizing the risk of deformation, thus structurally reinforcing each sub-cavity of the packing cavity.

[0046] As can be seen, the counterweight structure of this utility model can form a filling cavity by enclosing the surrounding plate 100 and the protective cover 200. The support member 300 is disposed in the filling cavity to divide the filling cavity into multiple sub-cavities. The cavity reinforcement member 400 is disposed in each sub-cavity of the filling cavity, and the edge of the cavity reinforcement member 400 is connected to the surrounding plate 100, the protective cover 200 and the support member 300 respectively to strengthen the structure of each sub-cavity of the filling cavity, thereby reducing the risk of deformation of the protective cover 200 of the counterweight structure and improving the reliability of the counterweight structure.

[0047] like Figure 1 and Figure 3 As shown, in an optional embodiment, the support member 300 includes a first support 310 and a second support 320. The first support 310 and the second support 320 are arranged in parallel to each other. The first support 310 and the second support 320 divide the filling cavity into a first side cavity, a middle cavity and a second side cavity. Both the first support 310 and the second support 320 have openings.

[0048] In this optional embodiment, refer to Figure 1 and Figure 3 The support component 300 is divided into a first support 310 and a second support 320, which are arranged parallel to each other in the packing cavity, thus dividing the packing cavity into three sub-cavities along the left-right direction: a first side cavity on the left side of the packing cavity, a middle cavity in the middle of the packing cavity, and a second side cavity on the right side of the packing cavity. Each of the first support 310 and the second support 320 has a left-right opening in the middle, allowing communication between the first side cavity, the middle cavity, and the second side cavity. When the amount of counterweight filler added to any sub-cavity exceeds a certain amount, the counterweight filler in that sub-cavity can flow through the opening to an adjacent sub-cavity, thereby ensuring that the weight distribution of the counterweight structure meets the preset balance range.

[0049] As can be seen, this optional embodiment can also divide the filling chamber into three sub-chambers through the first support 310 and the second support 320. The amount of filling material in different sub-chambers can be adjusted according to the needs when filling the counterweight filling material. And through the openings on the first support 310 and the second support 320, it can be ensured that the weight distribution of the counterweight structure can meet the required balance.

[0050] like Figure 3As shown, in an optional embodiment, the cavity reinforcement 400 includes: a first side cavity reinforcement 410, an intermediate cavity reinforcement 420, and a second side cavity reinforcement 430. The first side cavity reinforcing rib 410 is disposed in the first side cavity, and the edge of the first side cavity reinforcing rib 410 is connected to the side plate 120, the protective cover 200 and the support member 300 respectively. The first side cavity reinforcing rib 410 and the support member 300 are arranged perpendicular to each other. The middle cavity reinforcing rib 420 is disposed in the middle cavity, and the edge of the middle cavity reinforcing rib 420 is connected to the side plate 120, the protective cover 200 and the support member 300 respectively. The middle cavity reinforcing rib 420 and the support member 300 are arranged perpendicular to each other. The second side cavity reinforcing rib 430 is disposed in the second side cavity, and the edge of the second side cavity reinforcing rib 430 is connected to the side plate 120, the protective cover 200 and the support member 300 respectively. The second side cavity reinforcing rib 430 and the support member 300 are arranged perpendicular to each other. The first side cavity reinforcing rib 410, the middle cavity reinforcing rib 420 and the second side cavity reinforcing rib 430 are all provided with openings.

[0051] In this optional embodiment, refer to Figure 3 The cavity reinforcement 400 includes three reinforcing ribs: a first side cavity reinforcing rib 410, a middle cavity reinforcing rib 420, and a second side cavity reinforcing rib 430. The three reinforcing ribs are respectively disposed in their respective sub-cavities of the filling cavity. For example, the first side cavity reinforcing rib 410 is disposed in the first side sub-cavity, the middle cavity reinforcing rib 420 is disposed in the middle sub-cavity, and the second side cavity reinforcing rib 430 is disposed in the second side sub-cavity.

[0052] Each reinforcing rib in each compartment is arranged parallel to the top plate 110 and the bottom plate 130, and each reinforcing rib in each compartment has a vertically opening in the middle, thereby connecting the upper part of each compartment with the adjacent lower part. When the counterweight filler is filled into the filling cavity, each reinforcing rib can divert the counterweight filler, allowing the counterweight filler to be layered at the reinforcing rib, preventing the counterweight filler from accumulating at the bottom of the filling cavity, thereby reducing the compression on the bottom of the surrounding plate 100 and the protective cover 200, reducing the risk of deformation, and thus achieving structural reinforcement of each compartment of the filling cavity.

[0053] As can be seen, this optional embodiment can further strengthen the structure of each compartment by configuring corresponding reinforcing ribs in each compartment of the filling chamber, thereby further reducing the risk of deformation of the protective cover 200 of the counterweight structure.

[0054] like Figure 3 As shown, in an optional embodiment, there are multiple first side cavity reinforcing ribs 410, each of which is arranged parallel to each other; there are multiple second side cavity reinforcing ribs 430, each of which is arranged parallel to each other.

[0055] In this optional embodiment, each of the first side cavity and the second side cavity is provided with a plurality of reinforcing ribs. Each first side cavity reinforcing rib 410 in the first side cavity is arranged parallel to each other, and each second side cavity reinforcing rib 430 in the second side cavity is also arranged parallel to each other.

[0056] For example, refer to Figure 3 The first side cavity is provided with three first side cavity reinforcing ribs 410, and the second side cavity is provided with three second side cavity reinforcing ribs 430. When the counterweight filler is filled into the filling cavity, each reinforcing rib can divert the counterweight filler, so that the counterweight filler is layered at each reinforcing rib in the two side cavities, thereby dividing the counterweight filler in each cavity into four layers, thus preventing the counterweight filler from accumulating at the bottom of the filling cavity, thereby further strengthening the structure of each cavity of the filling cavity.

[0057] As can be seen, this optional embodiment can further reduce the compression on the bottom of the enclosure 100 and the cover 200 by providing multiple reinforcing ribs in both sides of the filling cavity, and further reduce the risk of deformation of the cover 200 of the counterweight structure.

[0058] In an optional embodiment, the top plate 110 is provided with a filler filling port, which communicates with the filler cavity. In this optional embodiment, the filler filling port is located on the top plate 110 at the top of the enclosure body 100, and the filler cavity inside the counterweight structure communicates with the filler filling port, allowing external counterweight filler to be filled into the filler cavity through the filler filling port.

[0059] As can be seen, this optional embodiment can also fill the external counterweight filler into the filler cavity through the filler filling port, thereby realizing the weight adjustment of the counterweight structure.

[0060] like Figure 3 As shown, in an optional embodiment, the filler filling port includes a first side filling port, a middle filling port, and a second side filling port. The first side filling port is connected to a first side sub-cavity, the middle filling port is connected to a middle sub-cavity, and the second side filling port is connected to a second side sub-cavity.

[0061] In this optional embodiment, refer to Figure 3 Each of the first side cavity, the middle cavity, and the second side cavity is equipped with a corresponding filling port for filling and assembling the packing material. During filling and assembling, the amount of packing material can be adjusted for different cavities according to requirements through the corresponding filling port. Specifically, the first side filling port is connected to the first side cavity, allowing the packing material to be filled into the first side cavity through the first side filling port; the middle filling port is connected to the middle cavity, allowing the packing material to be filled into the middle cavity through the middle filling port; and the second side filling port is connected to the second side cavity, allowing the packing material to be filled into the second side cavity through the second side filling port.

[0062] As can be seen, this optional embodiment can also provide a corresponding filling port for each sub-cavity of the filling chamber, so that when filling and assembling the refilling, the amount of filling can be adjusted for different sub-cavities according to the requirements through the corresponding filling port.

[0063] like Figure 3 As shown, in an optional embodiment, the top plate 110 has a first through hole and a second through hole. The lifting point of the first bracket 310 is disposed outside the top plate 110 through the first through hole, and the lifting point of the second bracket 320 is disposed outside the top plate 110 through the second through hole. Both the lifting point of the first bracket 310 and the lifting point of the second bracket 320 are connected to an external hanging device.

[0064] In this optional embodiment, refer to Figure 3 The first support 310 and the second support 320 both have a lifting point at their top ends, with an opening in the middle of each lifting point. The top plate 110 of the enclosure 100 also has a first through hole and a second through hole. The lifting point of the first support 310 passes through the first through hole to extend outside the counterweight device, and the lifting point of the second support 320 passes through the second through hole to extend outside the counterweight device. External suspension devices, such as those used on excavators or other construction machinery, connect to the openings on the lifting points to achieve counterweight mounting on the machinery. By adjusting the amount of counterweight filler injected into the filling chamber, the weight of the construction machinery can be adjusted, ensuring the safety and stability of the construction machinery's operation.

[0065] As can be seen, this optional embodiment can also extend to the outside through the corresponding through holes of the top plate 110 via the lifting points of the two supports, and connect the lifting points to the hanging device of the external construction machinery, thereby realizing the counterweight mounting of the construction machinery and the adjustment of the weight of the construction machinery, ensuring the safety and stability of the construction machinery operation.

[0066] like Figure 3 As shown, in an optional embodiment, the counterweight structure further includes a first support 510 and a second support 520. The right-angled sides of the first support 510 are connected to the first bracket 310 and the base of the base plate 130, respectively; the right-angled sides of the second support 520 are connected to the second bracket 320 and the base of the base plate 130, respectively.

[0067] In this optional embodiment, refer to Figure 1The base plate 130 of the enclosure member has a base at the position of the middle cavity, which is adjacent to the first support 310 and the second support 320 respectively. The first support 510 and the second support 520 can both be set as a stable triangular structure, wherein one right-angled side of the first support 510 is connected to the side of the first support 310 located in the middle cavity, and the other right-angled side of the first support 510 is connected to the base, thereby enhancing the stability of the first support 310; one right-angled side of the second support 520 is connected to the side of the second support 320 located in the middle cavity, and the other right-angled side of the second support 520 is connected to the base, thereby enhancing the stability of the second support 320.

[0068] As can be seen, this optional embodiment can also enhance the stability of the two supports by configuring each of the two supports with a corresponding support.

[0069] like Figure 3 As shown, in an optional embodiment, a plurality of circumferential reinforcing ribs 600 are provided on the inner side of the side plate 120 and the inner side of the bottom plate 130, and each circumferential reinforcing rib 600 is arranged parallel to each other.

[0070] In this optional embodiment, refer to Figure 3 The reinforcing ribs 600 of the enclosure are provided on the inner wall of the enclosure body 100, specifically on the inner side of the side plate 120 and the inner side of the bottom plate 130. Each of the enclosure reinforcing ribs 600 is arranged in parallel with each other, thereby reducing the risk of the enclosure body 100 being deformed by the pressure of the counterweight filler and thus enhancing the structural stability of the enclosure body 100.

[0071] As can be seen, this optional embodiment can also reduce the risk of deformation of the enclosure body 100 due to the compression of the counterweight filler by setting the enclosure reinforcing ribs 600, thereby enhancing the structural stability of the enclosure body 100.

[0072] This utility model also discloses an excavator, which includes an excavator body and a counterweight structure described in the above embodiments of this utility model, wherein the counterweight structure is installed on the excavator body.

[0073] As can be seen, in this embodiment, the excavator can form a filling cavity by adopting the above-mentioned counterweight structure, which is formed by the enclosure plate 100 and the protective cover 200. The support member 300 is disposed in the filling cavity to divide the filling cavity into multiple sub-cavities. The cavity reinforcement member 400 is disposed in each sub-cavity of the filling cavity, and the edge of the cavity reinforcement member 400 is connected to the enclosure plate 100, the protective cover 200 and the support member 300 respectively, so as to strengthen the structure of each sub-cavity of the filling cavity, thereby reducing the risk of deformation of the protective cover 200 of the counterweight structure and improving the reliability of the counterweight structure.
