DETAILED DESCRIPTION

[0045] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0046] The existing working machine frame, such as an excavator frame, is an integral frame structure assembled and welded by a plurality of cross beams and a plurality of longitudinal beams. Since the integral frame is large, it is difficult to complete the electrophoresis smoothly when electrophoresis is performed due to the limitation of the size of the current electrophoresis tank. Moreover, when a component in the integral frame structure needs to be repaired or replaced, it needs to be disassembled gradually from the inside of the frame, such as removing the excess baffle, then removing the target component, and then carrying out the target component, which is very difficult to disassemble.

[0047] In order to solve the above technical problems, the embodiments of the present application will be described below in combination with Figures 1 to 11 .

[0048] On the one hand, the present application provides a working machine frame structure 1, as shown in Figures 1 to 3 , mainly comprising a main pump cabin frame 11, a radiator cabin frame 12 and an air filter cabin frame 13.

[0049] Specifically, the main pump cabin frame 11 includes a main pump cabin support 111 and a post-processing mounting frame 112, the inside of the main pump cabin support 111 is a mounting space, the post-processing mounting frame 112 is used for mounting the post-processing 114, the post-processing mounting frame 112 is mounted in the upper space of the main pump cabin support 111 and is lap-jointed and fixed to the upper end of the main pump cabin support 111, that is, the upper part of the post-processing mounting frame 112 is first lap-jointed on the top of the main pump cabin support 111 and then fastened by fasteners; the opposite sides of the post-processing mounting frame 112 are respectively provided with lap-jointed segments 1124 extending to the side where the radiator cabin frame 12 is located, and the main pump cabin support 111 is located below the space of the post-processing mounting frame 112 to form a main pump cabin space for mounting the main pump cabin. Thus, the main pump cabin frame 11 is divided into two layers, the upper layer is used for mounting the post-processing 114, such as an exhaust gas processor, and the lower layer is used for mounting the main pump cabin, and the main pump cabin is used for mounting the main pump and accessories.

[0050] Specifically, the radiator cabin frame 12 is connected with the main pump cabin frame 11 through the oppositely arranged connecting beams 14, one end of the connecting beam 14 is fastened with the top of the radiator cabin frame 12 through fasteners, and the lap-jointed segments 1124 of the post-processing mounting frame 112 are lap-jointed on the other end of the connecting beam 14 and fastened through fasteners.

[0051] Specifically, the air filter cabin frame 13 is detachably mounted on one side of the radiator cabin frame 12, for example, the top cross beam 17 of the air filter cabin frame 13 can be connected with the top cross beam 17 of the air filter cabin frame 13 through fasteners.

[0052] The embodiment splits the working machine frame structure 1 into the main pump cabin frame 11, the radiator cabin frame 12 and the air filter cabin frame 13, which are separately produced and assembled into the whole working machine frame 1, the independent cabins can be electrophoresed respectively, the volume of the independent cabins is small and can be within the size that can be borne by the electrophoresis pool, so that the existing electrophoresis pool can be used for electrophoresis operation, the electrophoresis is convenient and the cost is controllable; moreover, after the electrophoresis of each independent cabin, the assembly between the cabins can be performed after the assembly of the accessories required by each cabin is completed, the assembly efficiency is high, the existing working machine frame 1 needs to be transported to each assembly link for accessory assembly, which saves the transportation cost, electrophoresis cost and reduces the assembly rhythm.

[0053] Moreover, after the main pump cabin frame 11 and the radiator cabin frame 12 are assembled together through the connecting beam 14, the pair of overlapping sections 1124 of the rear treatment mounting rack 112 are just overlapped on the upper surface of the connecting beam 14 and fastened through fasteners. When the rear treatment 114 needs to be maintained or replaced, only the fasteners need to be unscrewed, and the rear treatment mounting rack 112 can be hoisted from the main pump cabin support 111 by using a hoisting tool. After the replacement or maintenance of the rear treatment 114 is completed, the rear treatment mounting rack 112 is hoisted and installed on the main pump cabin support 111 by using the hoisting tool. The disassembly and assembly are convenient, and the maintenance and replacement of the rear treatment 114 are convenient. Compared with the existing working machine frame 1, which needs to be disassembled from the inside to separately disassemble the rear treatment 114, the working efficiency is greatly improved. That is, when the after-sales maintenance is performed, only the part that needs to be maintained needs to be disassembled, and the maintenance efficiency is improved.

[0054] It is further needed to be explained that the rear treatment mounting rack 112 and the main pump cabin support 111 can be separately pre-assembled, then the rear treatment 114 is installed in the rear treatment mounting rack 112, the main pump cabin is installed in the lower space of the main pump cabin support 111, and the main pump and accessories are assembled in the main pump cabin. After the pre-assembly is completed, the hoisting is performed to the assembly main line. In this way, the assembly rhythm can be saved.

[0055] The air filter cabin frame 13 is used for installing the air filter cabin. The air filter cabin is pre-assembled with the electrical fuse box, relay, sponge, etc. (the required components can also be pre-assembled according to the project requirements). After the pre-assembly is completed, the hoisting is performed to the assembly main line, and the assembly rhythm can be saved. The radiator cabin frame 12 is used for installing the radiator cabin and the engine cabin. The radiator cabin is used for installing the radiator, and the engine cabin is used for installing the engine.

[0056] After the main pump cabin frame 11, the radiator cabin frame 12, and the air filter cabin frame 13 are hoisted to the assembly line, they are fixed to the chassis platform 2 of the working machine through bolts, and the cabin frames are fixed through the connecting beam 14. The main pump cabin frame 11, the radiator cabin frame 12, and the air filter cabin frame 13 are integrally connected to form an L-shaped structure.

[0057] In a specific embodiment, as shown in Figure 5 and Figure 6 The radiator cabin frame 12 and the air filter cabin frame 13 each include a plurality of vertical columns 15. The bottom of each vertical column 15 is provided with a plurality of positioning pins 151. Preferably, the plurality of positioning pins 151 are not arranged in a row, for example, in a triangular or quadrilateral shape. In this way, the positioning reliability and stability can be improved.

[0058] The work machine frame structure 1 further comprises a plurality of mounting supports 16 adapted to be mounted on the chassis platform 2 of the work machine, the mounting supports 16 are provided with pin mounting holes 161 corresponding to the positioning pins 151 one by one, the upright column 15 is tenon-jointed to the pin mounting holes 161 and positioned and connected with the mounting supports 16 through the positioning pins 151, and is fixed through welding. The specific welding method can be spot welding or welding around the supports and the bottom of the upright column 15. The specific welding method can be selected according to the needs, which is not limited here. After the positioning pins 151 of the upright column 15 are inserted into the pin mounting holes 161 of the mounting supports 16, the position of the upright column 15 is determined, the perpendicularity of the upright column 15 and the chassis platform 2 of the work machine is guaranteed, and the flatness of the mounting supports 16 and the bottom surface of the upright column 15 is also guaranteed. Compared with directly welding the upright column 15 and the chassis platform 2 of the work machine, the dimensional accuracy, flatness and perpendicularity can be effectively guaranteed.

[0059] As can be seen, by providing a plurality of positioning pins 151 at the bottom of the upright column 15 and a plurality of pin mounting holes 161 corresponding to the positioning pins 151 on the mounting supports 16, the mounting supports 16 are first welded on the chassis platform 2 of the work machine, then the positioning pins 151 of the upright column 15 are aligned with the pin mounting holes 161 to realize tenon joint, thereby completing the preliminary positioning of the upright column 15, and then the bottom of the upright column 15 and the mounting supports 16 are welded, which can guarantee the accuracy, flatness and perpendicularity of the upright column 15 installation, thereby improving the installation accuracy of the entire work machine frame 1.

[0060] In a specific embodiment, as shown in Figure 2 The illustrated cross beams 17, radiator cabin frames 12 and air filter cabin frames 13 each further comprise a plurality of cross beams 17, each of which is fastened and connected with the top end of the upright column 15 through fasteners. Since the upright column 15 has been accurately positioned without accumulated errors, when the cross beams 17 are installed, they only need to be fastened and connected with the top end of the upright column 15 through fasteners, which is convenient and efficient.

[0061] In a specific embodiment, as shown in Figure 7 As shown, the main pump cabin support 111 has a partition plate mounting side facing the radiator cabin frame 12, a plurality of main pump cabin partition plates 113 are spliced on the partition plate mounting side, and a through hole for passing through the main pump pipeline is surrounded in the middle area of the partition plate mounting side. The shape of the through hole is adapted to the outer contour shape of the main pump pipeline.

[0062] Since the main pump cabin needs to install power equipment such as main pump, it has a lot of noise when working. The main pump cabin is separated from other cabins by setting the main pump cabin partition 113, only leaving the through hole for the main pump pipeline to pass through, and the through hole shape matches the main pump pipeline, which can avoid noise leakage and has good sound insulation effect. In addition, the use of block type partition can reduce the assembly difficulty. According to the shape of the main pump pipeline, the appropriate block type partition shape is selected for assembly, which improves the assembly convenience of the partition and facilitates disassembly. The block type partitions can be connected by screws or bolts, and the adjacent block type partitions can be partially overlapped to facilitate screwing. Figure 7 As shown in the figure, it is divided into right upper partition 1131, right middle partition 1132, right lower partition 1133, left upper partition 1134 and left lower partition 1135, which improves the assembly convenience of the partition and facilitates disassembly. In addition, the radiator cabin frame 12 is provided with the installation of the radiator cabin and the engine cabin, and the engine cabin is located on one side close to the main pump cabin partition 113. Since the engine cabin is installed with the engine, a large amount of heat will be generated during work. By setting the main pump cabin partition 113, the heat transfer of the engine cabin is reduced, thereby improving the service life of the pipeline and components in the main pump cabin; the transmission of engine noise is reduced to meet the national standard requirements.

[0063] In a specific embodiment, as shown in the figure, Figures 8 to 10 The bottom of the main pump cabin support 111 is provided with a pair of bottom plates 19 arranged opposite to each other, and the bottom plate 19 is provided with a mounting hole. The bottom plate 19 is suitable for being fixed to the chassis platform 2 of the working machine by the anti-loose fastener 18.

[0064] The bottom of the existing main pump cabin support 111 is directly connected with the chassis platform 2 of the working machine by the bolt 181. After a long period of bearing, the bolt 181 is easy to loosen. The bottom plate 19 of the main pump cabin support 111 in the embodiment is fixed to the chassis platform 2 of the working machine by the anti-loose fastener 18, which can prevent loosening. Since the main pump cabin frame 11 needs to install heavy components such as main pump and post-processing 114, it itself bears a large gravity. The main pump cabin frame 11 and the chassis platform 2 of the working machine are connected by the anti-loose fastener 18, which can effectively maintain the stability and durability of the main pump cabin frame 11 after installation.

[0065] Specifically, the main pump cabin support 111 has four struts, and one bottom plate 19 is arranged at the bottom of each two struts to form a pair of bottom plates 19 arranged opposite to each other. The bottom plate 19 can increase the contact area of the main pump cabin support 111 and the chassis platform 2 of the working machine. It is also convenient to set the mounting hole.

[0066] In a specific embodiment, as shown in the figure, Figure 9As shown, the anti-loose fastener 18 includes a bolt 181, an anti-loose sleeve 182 and a gasket 183, the bolt 181 is arranged in the anti-loose sleeve 182 and the gasket 183 to fasten the bottom plate 19 to the chassis platform 2 of the working machine. By arranging the anti-loose sleeve 182, the distance between the head of the bolt 181 and the gasket 183 can be increased, thereby increasing the clamping force. The anti-loose sleeve 182 is a hollow structure, which can relieve the stress of the gasket 183 on one hand, and avoid the bolt 181 from loosening due to long-term vibration on the other hand. Specifically, the chassis platform 2 of the working machine is pre-arranged with nuts at positions opposite to the mounting holes, the bolt 181 passes through the anti-loose sleeve 182 and the gasket 183 and is screwed into the nuts of the chassis platform 2 to achieve fastening, and the anti-loose sleeve 182 is clamped between the bolt 181 and the nuts to increase the clamping force and achieve the anti-loose effect.

[0067] In a specific embodiment, as shown in Figure 8 The bottom plate 19 is provided with two groups of mounting holes, one group of mounting holes is a positioning circular hole 191, and the other group of mounting holes is an oblong hole 192. The length direction of the oblong hole 192 extends along the length direction of the bottom plate 19. The hole diameter of the positioning circular hole 191 is matched with the screw diameter of the bolt 181 connected thereto, so that the bolt 181 can be precisely positioned after passing through the positioning circular hole 191 without any shaking allowance, thereby achieving precise positioning.

[0068] The bolt 181 is arranged to pass through the positioning circular hole 191 in the present embodiment, which can ensure the assembly precision of the side of the main pump cabin support 111 provided with the positioning circular hole 191 and the chassis platform 2 of the working machine, especially when the side door 20 needs to be installed on the side of the main pump cabin support 111 provided with the positioning circular hole 191, the installation precision of the side door 20 can be ensured. By arranging the other group of mounting holes as the oblong hole 192, the assembly tolerance can be eliminated, the adjustment range can be increased, and thus the bottom plate 19 can be smoothly installed on the chassis platform 2 of the working machine.

[0069] In a specific embodiment, as shown in Figure 4 The post-processing mounting frame 112 includes a support plate 1121, support columns 1122 arranged at intervals around the support plate 1121, and mounting beams 1123 connecting the top portions of adjacent two support columns 1122. The mounting beams 1123 are arranged transversely and connect the top portions of the two support columns 1122. The end portions of a pair of mounting beams 1123 extend along the length direction thereof to form overlapping sections 1124, and no mounting beam 1123 is arranged between the support columns 1122 corresponding to the overlapping sections 1124. The mounting beams 1123 are adapted to be overlapped on the top portion of the main pump cabin support 111 and fastened by fasteners. The support plate 1121 and the support columns 1122 enclose a placement space for the post-processing 114.

[0070] In this embodiment, by not providing an installation beam 1123 between the support columns 1122 corresponding to a pair of overlapping sections 1124, an opening is formed, which facilitates the placement of the post-treatment 114 in the placement space from the opening. Moreover, the post-treatment mounting frame 112 has a simple structure. By forming a pair of overlapping sections 1124, the post-treatment mounting frame 112 can be integrally overlapped and installed on the main pump compartment bracket 111, and then integrally overlapped with the connecting beam 14, which facilitates disassembly and assembly with the connecting beam 14. This makes it easy to lift the post-treatment mounting frame 112 carrying the post-treatment 114 as a whole, which is convenient for after-sales maintenance or replacement.

[0071] In one specific embodiment, a door frame is provided on the side where the air filter compartment frame 13 connects to the radiator compartment frame 12, and a side door 20 is installed at the door frame, such as... Figure 11 As shown, an adjustment mechanism 21 is provided on one side of the door frame, and a lock hook is provided on the side door 20. The adjustment mechanism 21 includes an adjustment bracket 211, a latch 212, and a lock spring 213. The adjustment bracket 211 has an elongated hole along the X direction, and the adjustment bracket 211 is installed on the side wall of the door frame through the elongated hole in the X direction. The latch 212 has an elongated hole along the Y direction, and the latch 212 is installed on the adjustment bracket 211 through the elongated hole in the Y direction. The lock spring 213 is installed on the latch 212 and extends along the Z direction. The lock hook is adapted to hook onto the lock spring 213 to lock the side door 20.

[0072] It is understandable that X, Y, and Z are three mutually perpendicular directions in a spatial coordinate system, such as... Figure 11 As shown, the X, Y, and Z directions are marked respectively. This embodiment aims to provide the installation adjustment mechanism 21 with six degrees of freedom for adjustment. By setting the installation adjustment mechanism 21 on the door frame, which can be adjusted in all six directions in space, the docking of the lock hook and the lock spring 213 after the side door 20 is installed can be met, the orientation adjustment is convenient, and the installation difficulty of the side door 20 is reduced.

[0073] In addition to the side door 20 between the air filter compartment frame 13 and the radiator compartment frame 12, other places in the working machinery frame structure 1 may also be provided with side doors 20 as needed, which are not specifically limited here.

[0074] In the above embodiments, all the fasteners mentioned can be ordinary bolts.

[0075] On the other hand, such as Figure 3 As shown, the present invention also provides a working machine, comprising:

[0076] The chassis platform 2 may vary for each vehicle model, and no specific restrictions are made here.

[0077] The working machinery frame structure 1 is installed on the base platform 2, which can be assembled first and then welded.

[0078] Each frame unit of the above work machine frame structure 1 is produced separately, electrophoresed separately, and assembled after the assembly of each frame unit is completed, and then assembled together as a whole and mounted on the chassis platform 2, which is high in mounting efficiency, can improve the mounting efficiency of the entire work machine, saves transportation and electrophoresis costs, and improves assembly rhythm. Of course, each frame unit can also be hoisted onto the chassis platform 2 for assembly, and the specific process is not limited here.

[0079] The work machine of the embodiment includes but is not limited to excavators, cranes, and shovel trucks.

[0080] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
