Description

Technical Field

[0001] This application belongs to the field of construction machinery technology, specifically relating to a construction machinery frame and construction machinery. Background Technology

[0002] In the realm of construction machinery, skid steer loaders, for example, are loading devices that utilize the difference in linear speed between their two wheels to achieve steering. They are characterized by their small turning radius, flexible operation, versatility, and wide applicability. Skid steer loaders are commonly used in situations with limited working space, complex ground conditions, or frequent changes in task types. They are widely applied in infrastructure construction, dock operations, road maintenance, and farm operations, and can also serve as auxiliary equipment for large construction machinery. By changing different operating attachments, skid steer loaders can perform a variety of functions, including shoveling, stacking, lifting, digging, drilling, crushing, grabbing, trenching, sweeping, and compaction.

[0003] The frame of the work machinery mainly consists of a base frame and left and right columns. Each column has two ear plates with shaft holes spaced apart. The two rotating shafts of the work device pass through the shaft holes on the left and right columns to achieve installation. However, the left and right columns are welded to the base frame, and the coaxiality accuracy of the shaft holes on the left and right columns is required to be high, which makes the processing difficult, the column width is large, and the structure is not compact enough. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies, this application provides a work machinery frame and work machinery, which aims to solve the technical problems of the existing left and right uprights being difficult to process and having an insufficiently compact structure.

[0005] To achieve the above objectives, this application provides a work machinery frame, wherein the work machinery frame includes a frame body and a mounting assembly. The frame body includes a base frame and a column assembly, the column assembly including a first column and a second column disposed opposite to each other at one end of the base frame; the mounting assembly includes a mounting plate and a support base, the mounting plate being connected to the first column and the second column respectively, and the support base being disposed on the upper side of the mounting plate and having a shaft hole, the shaft hole allowing the rotating shaft of the work device to pass through.

[0006] In this embodiment of the application, there are two support seats. The two support seats are erected on the upper side of the mounting plate at intervals along the direction from the first column to the second column. Both support seats are provided with shaft holes.

[0007] In this embodiment of the application, both support bases include a hinge plate and a connecting arm.

The connecting arm is located on the side of the corresponding hinge plate away from the other hinge plate and is connected to a column arranged on the same side.

[0008] In this embodiment, the hinge plate includes an integrally bent hinge portion and a bent portion. The hinge portion has a shaft hole and is connected to a connecting arm. The bent portion is located at the end of the hinge portion away from the connecting arm. The connecting arm and the bent portion are arranged opposite each other with respect to the shaft hole and are respectively connected to the column arranged on the same side.

[0009] In this embodiment, the bent portion is inclined from the end of the hinge portion toward the column located on the same side.

[0010] In this embodiment of the application, the mounting assembly further includes a reinforcing rod, which is connected between the hinge plates of the two support seats and located at the connection between the hinge portion and the bent portion.

[0011] In this embodiment of the application, the support base is provided with a pin reinforcement seat, which includes a shaft sleeve and a reinforcing plate. The shaft sleeve passes through the support base and forms a shaft hole. The reinforcing plate is sleeved on the shaft sleeve and extends out of the support base. The plate surface of the reinforcing plate is attached to the support base, and the lower end of the reinforcing plate is connected to the mounting plate.

[0012] In this embodiment of the application, the inner sides of the first column and the second column are provided with bending support plates. The bending support plates are inclined upward in the direction from front to back. The mounting plate includes a flat plate body and a bending side plate. The flat plate body is horizontally connected between the inner sides of the first column and the second column and is used for the support seat to stand. The bending side plate is bent downward from one end of the flat plate body and overlaps the upper side of the bending support plate.

[0013] In this embodiment of the application, the base frame includes a support, a front sealing plate, and a clearance frame. The support forms an installation space with open ends. The two sides of the support are connected to the first column and the second column, respectively. The front sealing plate is located on the front side of the support and has an opening. The clearance frame is located at the opening and forms a clearance space. The clearance space is used to avoid the working device.

[0014] In this embodiment, both the first column and the second column have mounting cavities, and a connecting seat is provided in the mounting cavity. The work machinery frame also includes a battery mounting bracket, which is connected to the connecting seat and used for disassembly and connection with the battery module.

[0015] In the embodiments of this application, both the first column and the second column include a column body, an inner side plate and a connecting plate. The column body is connected to the mounting plate, the inner side plate is located inside the column body and spaced apart from the column body, and the connecting plate is connected between the column body and the inner side plate. The column body, the inner side plate and the connecting plate together form a mounting cavity.

[0016] In this embodiment, the battery mounting bracket includes a mounting part and a first connecting part and a second connecting part that are respectively connected to both ends of the mounting part. The first connecting part and the second connecting part are respectively connected to the connecting seats of the first column and the second column. The mounting part and the battery module are detachably connected by fasteners. The base frame also includes a base plate, which is disposed between the first column and the second column, and the base plate has mounting holes at the positions corresponding to the fasteners.

[0017] In addition, this application also provides a work machinery, which includes the work machinery frame as described above.

[0018] Through the above technical solution, the work machinery frame provided in this application embodiment has the following beneficial effects: In the technical solution of this application, the first column and the second column are located at the rear end of the base frame, and are arranged opposite to each other in the left-right direction. One end of the mounting plate is connected to the first column, and the other end of the mounting plate is connected to the second column to realize the installation and fixation of the mounting plate. A support base is located on the upper side of the mounting plate, and the support base has a shaft hole that extends in the left-right direction. The shaft hole allows the rotating shaft of the working device to pass through, so as to realize the installation of the working device.

[0019] This application utilizes a mounting plate positioned between the first and second columns, with a support base on the mounting plate. This allows for the installation of the rotating shaft of the working device solely through the machining of shaft holes in the support base. Compared to a design that uses two lugs on each column for shaft installation, this method offers a simpler structure. Furthermore, machining the shaft holes only on the support base reduces manufacturing complexity compared to machining shaft holes on each of the two columns separately while maintaining high coaxiality. Additionally, the reduced width of the columns results in a more compact structure for the working machinery frame.

[0022] Explanation of reference numerals in the attached figures Detailed Implementation

[0023] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0024] The descriptions of directions such as "up", "down", "front", "back", "left", and "right" in this application are as follows: Figure 1 The directions shown are for reference only and are used to interpret the location. Figure 1 The relative positional relationship between the components in the shown posture is such that if the specific posture changes, the directional indication will also change accordingly.

[0025] The following description of the work machinery frame and work machinery of this application is with reference to the accompanying drawings.

[0026] like Figures 1 to 13 As shown, this application provides a work machinery frame, which includes a frame body and a mounting assembly 30. The frame body includes a base frame 10 and a column assembly 20. The column assembly 20 includes a first column 21 and a second column 22 disposed opposite to each other at one end of the base frame 10. The mounting assembly 30 includes a mounting plate 31 and a support base 32. The mounting plate 31 is connected to the first column 21 and the second column 22 respectively. The support base 32 is disposed on the upper side of the mounting plate 31 and has a shaft hole 3213, which allows the rotating shaft of the work device 200 to pass through.

[0027] The first column 21 and the second column 22 are located at the rear end of the base frame 10, and are arranged opposite each other in the left-right direction. One end of the mounting plate 31 is connected to the first column 21, and the other end of the mounting plate 31 is connected to the second column 22 to realize the installation and fixation of the mounting plate 31. The support base 32 is located on the upper side of the mounting plate 31, and the support base 32 has a shaft hole 3213 extending in the left-right direction. The shaft hole 3213 allows the rotating shaft of the working device 200 to pass through, so as to realize the installation of the working device 200.

[0028] This application provides a mounting plate 31 between the first column 21 and the second column 22, and a support base 32 on the mounting plate 31. The rotating shaft of the working device 200 can be mounted simply by creating a shaft hole 3213 on the support base 32. This design is simpler than using two ear plates on each column for shaft mounting. Furthermore, machining the shaft hole 3213 only on the support base 32 reduces machining difficulty compared to machining the shaft hole 3213 on each of the two columns separately while maintaining high coaxiality. Simultaneously, the reduced width of the columns makes the working machinery frame more compact.

[0029] like Figure 4 As shown, the number of support bases 32 can be one, the working device 200 is provided with two connecting ear plates, the support base 32 is located between the two connecting ear plates, and the rotating shaft of the working device 200 passes through the support base 32 and the two connecting ear plates.

[0030] In another embodiment, please refer to Figure 5 There are two support seats 32. The two support seats 32 are erected on the upper side of the mounting plate 31 at intervals along the direction from the first column 21 to the second column 22. Both support seats 32 are provided with shaft holes 3213.

[0031] Two support bases 32 are spaced apart in the left-right direction, and both support bases 32 are erected on the upper side of the mounting plate 31. Each support base 32 has a shaft hole 3213. The working device 200 is positioned between the two support bases 32, and a rotating shaft passes through the working device 200 and the two support bases 32. By using two support bases 32 to support the working device 200, the force on the working device 200 is more evenly distributed, and the connection between the working device 200 and the support bases 32 is more stable and reliable.

[0032] Understandably, both support bases 32 are mounted on the mounting plate 31, and the distance between the two support bases 32 is small. The two support bases 32 can be connected to the mounting plate 31 first, and then the shaft holes 3213 can be machined on both support bases 32 at once using a boring machine to ensure the coaxiality of the shaft holes 3213 on both support bases 32. Compared to machining the shaft holes 3213 on each of the two columns separately while ensuring coaxiality, this process is less difficult.

[0033] In the embodiments of this application, please refer to Figure 6 Both support bases 32 include a hinge plate 321 and a connecting arm 322. The hinge plates 321 of the two support bases 32 are arranged at intervals and each has a shaft hole 3213. Each hinge plate 321 of the support base 32 is connected to a connecting arm 322. The connecting arm 322 is located on the side of the corresponding hinge plate 321 that is away from the other hinge plate 321 and is connected to the column arranged on the same side.

[0034] The hinge plates 321 of the two support bases 32 are spaced apart from each other in the left-right direction, and the hinge plates 321 are provided with shaft holes 3213 for the rotating shaft of the working device 200 to pass through. The connecting arm 322 extends in the left-right direction and is connected to the hinge plate 321. The connecting arm 322 is located on the side of the corresponding hinge plate 321 away from the other hinge plate 321, and the connecting arm 322 is connected to the column provided on the same side. By setting the connecting arm 322 to be connected to the column provided on the same side, the connection stability and reliability of the mounting assembly 30 and the column assembly 20 are improved.

[0035] In the embodiments of this application, please refer to Figure 6 The hinge plate 321 includes an integrally bent hinge portion 3211 and a bent portion 3212. The hinge portion 3211 has a shaft hole 3213 and is connected to a connecting arm 322. The bent portion 3212 is located at the end of the hinge portion 3211 away from the connecting arm 322. The connecting arm 322 and the bent portion 3212 are arranged opposite each other with respect to the shaft hole 3213 and are respectively connected to the column arranged on the same side.

[0036] The hinge portion 3211 extends in the front-to-back direction and has a shaft hole 3213. The hinge portion 3211 is connected to the connecting arm 322. The hinge portion 3211 and the bending portion 3212 are integrally bent, saving assembly steps. The bending portion 3212 is located at the end of the hinge portion 3211 away from the connecting arm 322. The connecting arm 322 and the bending portion 3212 are respectively located on the front and rear sides of the shaft hole 3213, and are respectively connected to the column on the same side. By connecting the bending portion 3212 to the column on the same side, the connection stability and reliability between the mounting assembly 30 and the column assembly 20 are further improved. Furthermore, the front and rear sides of the shaft hole 3213, with the connecting arm 322 and the bending portion 3212 respectively, result in more even force distribution on both sides of the rotating shaft.

[0037] Based on this, the bending portion 3212 is inclined from the end of the hinge portion 3211 toward the column provided on the same side. In other words, the bending portion 3212 is inclined in the direction from front to back toward the column provided on the same side to facilitate the connection between the bending portion 3212 and the column provided on the same side.

[0038] In the embodiments of this application, please refer to Figure 6 The mounting assembly 30 also includes a reinforcing rod 33, which connects the hinge plates 321 of the two support seats 32 and is located at the connection between the hinge portion 3211 and the bending portion 3212. By providing the reinforcing rod 33 between the hinge plates 321 of the two support seats 32, the structural strength of the mounting assembly 30 is improved, thereby enhancing the structural stability and reliability of the mounting assembly 30. Furthermore, the reinforcing rod 33, located at the connection between the hinge portion 3211 and the bending portion 3212, prevents breakage at the connection between the hinge portion 3211 and the bending portion 3212.

[0039] In the embodiments of this application, please refer to Figure 6 The support base 32 is provided with a pin reinforcing seat 34, which includes a shaft sleeve 341 and a reinforcing plate 342. The shaft sleeve 341 passes through the support base 32 and forms a shaft hole 3213. The reinforcing plate 342 is sleeved on the shaft sleeve 341 and extends out of one end of the support base 32. The plate surface of the reinforcing plate 342 is attached to the support base 32, and the lower end of the reinforcing plate 342 is connected to the mounting plate 31.

[0040] The shaft assembly 341 extends in the left-right direction and passes through the support base 32. The shaft assembly 341 has a shaft hole 3213. By fitting the shaft assembly 341 onto the outside of the rotating shaft, the installation of the rotating shaft becomes more stable. A reinforcing plate 342 is fitted onto the end of the shaft assembly 341 that extends out of the support base 32. The reinforcing plate 342 is located on the side of the support base 32 near the column on the same side. The surface of the reinforcing plate 342 is attached to the support base 32, and the lower end of the reinforcing plate 342 is connected to the mounting plate 31. By providing the reinforcing plate 342 to enhance the structural strength at the shaft hole 3213, the structural strength of the mounting assembly 30 is increased.

[0041] In the embodiments of this application, please refer to Figure 6 and Figure 7 The inner sides of the first column 21 and the second column 22 are provided with a bending support plate 211. The bending support plate 211 is inclined upward in the direction from front to back. The mounting plate 31 includes a flat body 311 and a bending side plate 312. The flat body 311 is horizontally connected between the inner sides of the first column 21 and the second column 22 and is used to support the base 32. The bending side plate 312 is bent downward from one end of the flat body 311 and overlaps the upper side of the bending support plate 211.

[0042] A bending support plate 211 is located inside the first column 21 and the second column 22, and is inclined upwards in the front-to-back direction. A flat plate body 311 is horizontally oriented, with its left and right ends connected to the inner sides of the first column 21 and the second column 22, respectively. A support base 32 is erected on the flat plate body 311. A bending edge plate 312 is bent downwards from one end of the flat plate body 311, allowing it to overlap the upper side of the bending support plate 211. The inclined bending edge plate 312 and the bending support plate 211 increase the connection area between the mounting plate 31 and the column assembly 20, making the connection between them more stable and reliable. Furthermore, the downward bending of the bending edge plate 312 from one end of the flat plate body 311 allows it to avoid obstructing the working device, making its use more convenient.

[0043] In the embodiments of this application, please refer to Figures 7 to 11 The first column 21 and the second column 22 both have mounting cavities 212, and the mounting cavity 212 is provided with a connecting seat 213. The frame of the working machinery also includes a battery mounting bracket 40, which is connected to the connecting seat 213 and is used for detaching and connecting with the battery module 60.

[0044] The connecting seat 213 is located inside the mounting cavity 212. The battery mounting bracket 40 is connected to the connecting seat 213 to realize the installation and fixation of the battery mounting bracket 40, making full use of the space of the first column 21 and the second column 22, and improving the structural compactness of the operating machinery. The battery mounting bracket 40 is used for detaching and connecting to the battery module 60, which facilitates the replacement and maintenance of the battery module 60, making the use of the battery module 60 more flexible and convenient.

[0045] Furthermore, the battery module 60 is located at the rear of the work machinery, which shifts the vehicle's center of gravity rearward. This rearward center of gravity increases the loading capacity for the same tonnage. A maintenance window 50 is provided at the rear of the work machinery frame, allowing for maintenance of the battery module 60 and electrical components such as the radiator, thus improving the convenience of disassembly, assembly, and maintenance of the battery module 60.

[0046] Based on this, please refer to Figure 11 The first column 21 and the second column 22 both include a column body 214, an inner side plate 215 and a connecting plate 216. The column body 214 is connected to the mounting plate 31. The inner side plate 215 is located inside the column body 214 and is spaced apart from the column body 214. The connecting plate 216 is connected between the column body 214 and the inner side plate 215. The column body 214, the inner side plate 215 and the connecting plate 216 enclose and form a mounting cavity 212.

[0047] The column body 214 is connected to the mounting plate 31 to fix the mounting plate 31. The inner side plate 215 is provided on the inner side of the column body 214, and the inner side plate 215 is spaced apart from the column body 214. The outer contour of the inner side plate 215 is approximately L-shaped. One side of the connecting plate 216 is connected to the column body 214, and the other side of the connecting plate 216 is connected to the inner side plate 215. The connecting plate 216 extends from one end of the inner side plate 215 to the other end. The column body 214, the inner side plate 215, and the connecting plate 216 enclose a mounting cavity 212 to accommodate the connecting seat 213 within the mounting cavity 212.

[0048] Specifically, the column body 214 includes a middle side plate 2142 and an outer side plate 2141. The outer side plate 2141 is connected to the outer side of the middle side plate 2142. A connecting plate 216 is connected between the outer side plate 2141 and the inner side plate 215. The outer side plate 2141 protrudes outward to make the space of the mounting cavity 212 larger, which facilitates the installation of the connecting seat 213. At the same time, it also makes the connecting plate 216 larger in the left and right direction, which can block the mud and water splashed by the rotating wheel and play a protective role.

[0049] In the embodiments of this application, please refer to Figures 7 to 9The battery mounting bracket 40 includes a mounting part 41 and a first connecting part 42 and a second connecting part 43 respectively connected to both ends of the mounting part 41.

Furthermore, the first connecting portion 42 and the second connecting portion 43 are respectively connected to the connecting seats 213 of the first column 21 and the second column 22 to realize the installation and fixation of the battery mounting bracket 40. The mounting portion 41 and the battery module 60 are connected and detached by fasteners. Specifically, the fasteners are bolts. Bolts have the advantages of being easy to obtain and convenient to install. In addition, the threaded connection can be self-locking, making the connection between the battery module 60 and the mounting portion 41 tighter and more reliable.

[0051] Please see Figure 12 The base plate 14 is located between the first column 21 and the second column 22. The base plate 14 and the mounting plate 31 are arranged opposite each other in the vertical direction. The base plate 14 has mounting holes 141 at the positions of the fasteners. The mounting holes 141 facilitate the installation and removal of the battery module 60, making the use of the battery module 60 more flexible and convenient. Understandably, during maintenance, the fasteners at the mounting holes 141 can be loosened to separate the battery module 60 from the mounting part 41, and then the battery module 60 can be removed through the maintenance window 50 at the rear of the work machinery frame.

[0052] Furthermore, a drainage hole is provided on the base plate 14 to allow water inside the base frame 10 to drain out in a timely manner.
