[0002] Engine repair workbenches typically employ a fixed structure, which is inconvenient to use. To address this issue, repair stations have developed various types of repair platforms. For example, CN202420661157.8 discloses an auxiliary heating electric lighting device for automotive engine repair platforms. This device solves the problem that traditional lighting fixtures are inflexible and increase the workload of repair work when repairing and maintaining automotive engines at night.

[0003] For example, CN202223221018.3 discloses a lifting platform for automobile engine maintenance, which solves the problem that existing engine maintenance platforms cannot adjust their operating height according to the height of the operator.

[0004] In actual maintenance, depending on the structural characteristics of different types of engines, the maintenance platform needs to be tilted during disassembly and testing to facilitate better observation and pairing with testing instruments. Current maintenance platforms do not have this function and have a simple structure. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an engine maintenance platform that solves the problem that existing maintenance platforms cannot tilt within a certain angle range.

[0032] An engine maintenance platform with sufficient rigidity is described below in conjunction with the appendix to the instruction manual. Figure 1 To be continued Figure 7 The structure of this maintenance platform will be described in more detail. The technical terminology used in this description will be as accurate as possible. Even so, there may still be inaccuracies. Please understand.

[0033] The maintenance platform includes a support frame 100, a platform 200, a drive mechanism 300, a hydraulic support rod 400, and a robotic arm 500. The support frame 100 is formed by welding steel profiles and adding appropriate ribs. The welded support frame is U-shaped and consists of two support legs 110 on both sides and a connecting beam 120 at the bottom. A base plate 130 is welded to the bottom of each support leg. This base plate has a flat structure and multiple height-adjustable anchor bolts 140 along its edge, allowing adjustment of the platform's levelness. Each support leg has a double-column structure, and a top plate 150 is welded to the top of each support leg 110, serving as the mounting base for the platform.

[0034] The platform 200 consists of a flat plate 210 and a flat plate fixing frame 220. Specifically, the flat plate 210 is made of thick steel plate and has a T-shaped straight groove 211 on it. T-bolts are used in the T-shaped straight groove to temporarily fix the engine. Below the flat plate 210 is the flat plate fixing frame 220, which is a welded frame with a U-shaped structure. The flat plate fixing frame and the flat plate are fixed together by welding or bolting to form an integral structure. An L-shaped support member 230 is fixed or bolted to both sides of the flat plate fixing frame. The horizontal arm of the support member 230 is fixedly connected to the frame, and the vertical arm of the support member 230 is welded and fixedly connected to the rotating disk 240 or the gear disk 250. The rotating disk and the gear disk are circular disks and are symmetrically arranged on both sides of the flat plate mounting frame. After welding and fixing, the plane on which the flat plate 210 is located is eccentric to the axis X between the two rotating disks and the gear disk. This structure is beneficial to the mechanical stability of the overall structure.

[0035] Both the rotating disk 240 and the gear disk 250 are disc-shaped parts. The difference between the two is that the gear disk has evenly distributed teeth.

[0036] A bearing seat 260 is provided on the top plate 150 of each of the aforementioned support legs 110. The bearing seat 260 houses a bearing and a main shaft. The main shaft is rotatably mounted on the top plate of the support leg via the bearing and bearing seat, with the X-axis as its rotation center. The end of the main shaft is fixed to the aforementioned rotating disk or gear disk and is coaxially arranged. Thus, under the drive of an external force, the aforementioned platform can rotate relative to the axis of the main shaft, adjusting the tilt state of the platform during rotation—that is, whether it is tilted or horizontal.

[0037] On the aforementioned top plate 150, a stepper motor 310, a worm gear reducer 320, and a pinion 330 are also provided, which interact with the gear disk. The stepper motor 310 is fixed to the top plate via a motor mounting bracket. The stepper motor is connected to the worm gear reducer for transmission. The pinion is mounted on the power output shaft of the worm gear reducer, and meshes with the toothed gear disk. The stepper motor, worm gear reducer, and pinion constitute the drive mechanism 300. The driving process is as follows: the stepper motor drives the pinion to rotate slowly through the worm gear reducer. During rotation, the pinion slowly adjusts the position of the engine's platform. During this process, the worm gear has a reverse self-locking capability. When the stepper motor is powered off, even if external force is applied to the gear disk, the gear disk cannot rotate because the worm gear reducer has a reverse locking capability.

[0038] A pin is installed on each of the aforementioned rotating disk 240 and gear disk 250. The pin is used for the installation of the hydraulic support rod 400. Specifically, the lower end of the hydraulic support rod 400 is hinged to the crossbeam of the support frame, and the upper end is hinged to the aforementioned pin. The hydraulic support rod 400 provides auxiliary support to the rotating disk and gear disk on both sides, which has positive significance for the stability performance when the engine is in the loading state.

[0039] Furthermore, a hydraulic support rod 400' is also installed between the middle of the shelf 200 and the crossbeam of the aforementioned support frame. The installation method involves welding an arc-shaped rib plate to the frame on the back side of the shelf, the arc-shaped rib plate being perpendicular to the shelf plate. A pin is installed on the arc-shaped rib plate for mounting the hydraulic support rod. This hydraulic support rod supports the shelf from the middle, improving the stability of the shelf.

[0040] Furthermore, an electrical control box 600 is fixed to the back side (lower surface) of the shelf, and the electrical control box is fixed to the back side of the shelf and moves together with the shelf.

[0041] Furthermore, a lateral and longitudinal adjustable robotic arm 500 is also provided on the aforementioned platform. The robotic arm has a mounting part that can be used to mount and adjust tools, such as electric grinding tools. The installation of this robotic arm can further reduce the labor intensity during the maintenance process.

[0042] Furthermore, an encoder 700 is also installed on the top plate. The probe of the encoder is aligned with the edge of the gear disk to read the rotation data of the teeth. Through the encoder 700, the rotation angle of the gear disk can be accurately obtained, and the tilt angle of the platform can be calculated from the rotation angle.

[0043] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Without departing from the spirit of the present utility model, all modifications and improvements to the present utility model by those skilled in the art should fall within the protection scope defined by the claims of the present utility model.
