Description

Technical Field

[0001] This utility model belongs to the technical field of heavy-duty vehicle frame structure, and in particular relates to a heavy-duty vehicle frame structure with an erection device interface. Background Technology

[0002] Heavy-duty trucks require high load-bearing capacity and lightweight construction, resulting in large and heavy superstructures. This necessitates high installation stability and flexibility and reliability when the superstructures are erected for work.

[0003] In the prior patent "An integrated frame with floating support and a vehicle" (application number: CN202211384937.4), the lower support of the tilting cylinder of the superstructure is set in the bottom plate inside the longitudinal beam of the frame and integrated with the rear tail beam of the special frame. This allows for the reasonable arrangement of the tilting cylinder seat and the rotation center point without using a subframe, thereby lowering the center of gravity of the superstructure and ensuring driving safety. Furthermore, the rear beam of the frame is designed to be integrated with the longitudinal beam of the frame, taking into account both the support of the cylinder legs during the operation of the superstructure and the load-bearing requirements when the superstructure is tilted. However, in this structure, the rotation center of the superstructure is located at the rear end of the frame. For overall stability, the swing angle of the superstructure cannot be too large, and the flexibility of the superstructure's erection action needs to be improved. Utility Model Content

[0034] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0035] A heavy-duty vehicle frame structure with an erection device interface

[0036] The system includes an automobile frame structure 1, a workbench body assembly 2, and an erection device interface structure mounted on the automobile frame structure 1. The workbench body assembly 2 serves as the erection device and is connected to the automobile frame structure 1 via the erection device interface structure and the workbench body hydraulic cylinder 3. Figures 1-2 As shown, the automobile frame structure 1 includes left and right longitudinal beams 110, and various crossbeams and support legs 120 installed on the left and right longitudinal beams 110. The erection device interface structure includes an erection slewing support 210, an erection electric cylinder seat 220, a fixed support 230, etc.

[0037] The support body of the erecting device is a heavy-duty vehicle frame structure 1. The vehicle frame structure includes two parallel extended frame left and right longitudinal beams 110. The frame left and right longitudinal beams 110 are fixed by bolts on each crossbeam. When the erecting device is in operation, the overall structure is supported and fixed by outriggers. Specifically, the outriggers are hydraulic cylinder outriggers. When the erecting device is working, the hydraulic cylinder outriggers lift the entire vehicle off the ground.

[0038] Two sets of erection and slewing supports 210 are installed on the upper plane of the left and right longitudinal beams 110 at the rear of the frame. A set of electric erection cylinder seats 220 is positioned in front of the erection and slewing supports 210. Both sets of erection and slewing supports 210 are connected to the workbench body assembly. The front-positioned electric erection cylinder seat 220 is connected to the workbench body hydraulic cylinder 3, which is an electric hydraulic cylinder. Figure 1 As shown, a three-hinge structure is formed, and the working angle of the worktable body is adjusted by three points.

[0039] like Figure 1 and Figure 6 As shown, support legs 120 are provided at the front and rear ends of the left and right longitudinal beams 110 of the frame to fix the support legs. The support legs 120 at the rear end are located at the front end of the fixed support 230 and on both sides of the erection and slewing support 210.

[0040] like Figures 2-3 As shown, the limiter support 240 is located in the middle section of the frame. When the worktable body is not in use, the limiter support 240 in the middle of the frame fixes the front end of the worktable body, making it more secure. The limiter support 240 is bolted to the limiter 4 of the worktable body through four connecting plates 241, facilitating subsequent disassembly and assembly. The connecting plates are connected to the left and right longitudinal beams through the crane fixing bracket 242. When the worktable body is in use, the front limiter is unlocked, and the angle of the worktable body is adjusted by stretching three sets of hydraulic cylinders.

[0041] like Figure 4 and Figure 5 As shown, the erecting slewing support 210 includes a slewing lug 211 and a cylinder liner 212 disposed within the slewing lug 211. The slewing lug 211 and the cylinder liner 212 are interference-fitted to transmit large torque. The cylinder liner is made of copper tubing. During operation, the copper liner acts as a bearing and requires a lubrication system. Therefore, lubrication oil filling ports are provided on the slewing lug and the cylinder liner to ensure that the cylinder liner operates smoothly, reliably, and without noise.

[0042] The erecting slewing support 210 is fixed by reinforcing ribs 213, reinforcing beams 214 and support beams 215 welded to box-shaped reinforcing beam welds 216. The bottoms of two sets of slewing lugs 211 are inserted into the box-shaped reinforcing beam welds 216. Two sets of process holes are opened on each side of the upright plate of the reinforcing beam 214, which are then welded to the slewing lugs to ensure the sturdiness and reliability of the erecting slewing support 210. The reinforcing ribs 213 and reinforcing beams 214 are both triangular and located on both sides of the slewing lugs 211, respectively. The support beam 215 is located between the two slewing lugs 211 on the same side.

[0043] Two sets of erecting and slewing supports 210 are welded to the left and right longitudinal beams 110 of the frame via box-type reinforcing beams 216. The left and right longitudinal beams are connected by crossbeams 217 located at the erecting and slewing supports, forming a strong, reliable and powerful structure.

[0044] like Figure 7 and Figure 8 As shown, the lifting electric cylinder seat 220 is precisely positioned on the machine tool before the lifting slewing support 210. The lifting electric cylinder seat 220 includes a lifting support lug 221 and a base plate 222. The two structural components are welded together and then welded onto the crossbeam 223 located at the lifting electric cylinder seat. The crossbeam 223 located at the lifting electric cylinder seat is reinforced and connected to the left and right longitudinal beams of the frame through the side plates 224. The rear end face of the lifting electric cylinder seat 220 bears part of the recoil force through two support beams 225 connected to the left and right longitudinal beams 110 of the frame, and transmits it to the left and right longitudinal beams of the frame.

[0045] The fixed support 230 is located at the rear of the frame, at the ends of the left and right longitudinal beams. It provides support when the angle of the workbench body exceeds a certain limit, thus improving overall stability. Figure 6 As shown, the fixed support 230's overall frame includes five workbench connecting plates 231, top and bottom support plates 232, and the support plates 232 are connected by side crossbeams 233 and a middle crossbeam 234. The upper and lower support plates 232 are welded to the rear of the left and right longitudinal beams 110 of the frame, along with the side crossbeams 233 and the middle crossbeam 234. When the workbench body is flipped backward into position, it is fixed to the workbench connecting plates by a limiting device at the rear of the workbench body, providing auxiliary support.

[0046] The workbench body 2 is equipped with a support base 5 at the rear. When it is raised to the maximum angle, the support base 5 contacts the fixed support 230 to ensure the stability of the overall structure.

[0047] All connection holes and surfaces of the worktable body in the heavy-duty truck frame structure are machined integrally on a lathe with the center of the vertical slewing support as the coordinate origin, ensuring the accuracy of the entire frame and the practicality and reliability of the connection interfaces. This device has a stable structure and can achieve a 60° tilt angle for the worktable body.

[0048] This utility model provides a heavy-duty truck frame structure with an erection device, which improves the flexibility of the working device body and is of great significance for reducing the weight of the whole vehicle, improving work efficiency, improving the reliability of the whole vehicle and reducing the cost.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
