Description

Technical Field

[0001] This utility model relates to the field of heavy-duty omnidirectional AGV robot technology, and in particular to a shell mechanism for easy disassembly and maintenance of heavy-duty omnidirectional AGV robots. Background Technology

[0002] Heavy-duty omnidirectional AGV robots are widely used in logistics transfer, intelligent manufacturing, and other scenarios. Their outer shell structure must simultaneously meet two core requirements: first, to protect internal core components such as the power module, PDU module, ACU module, dual differential speed servo mechanism, and screw lifting mechanism from external interference; and second, to have convenient maintenance functions to ensure continuous equipment operation. However, existing AGV shells mostly adopt an integral or highly integrated spliced ​​structure. When internal components malfunction and require maintenance, the entire body shell, lifting mechanism protective shell, and even the lifting plate must be disassembled. This is not only cumbersome and time-consuming, but also prone to component wear due to frequent disassembly and assembly, severely reducing the maintenance efficiency and operational stability of the AGV.

[0003] Meanwhile, as a key component that directly bears heavy loads, the existing design of the lifting platform generally lacks effective anti-slip treatment, which can easily cause safety hazards due to material slippage during transportation and cannot meet the stable transportation requirements in heavy-load scenarios.

[0004] Therefore, the industry urgently needs an AGV shell mechanism that can achieve both rapid partial disassembly and maintenance and reliable anti-slip performance, in order to solve the dual pain points of inconvenient maintenance and poor anti-slip performance of the existing structure. Utility Model Content

[0005] The purpose of this utility model is to overcome the problems of the prior art and provide a shell mechanism for easy disassembly and maintenance of heavy-duty omnidirectional AGV robots. This solves the technical problems of existing AGV shell maintenance requiring complete disassembly, which is time-consuming and wasteful, and the lifting plate has insufficient anti-slip properties, making materials easy to slip.

[0006] The above objectives are achieved through the following technical solutions: A convenient disassembly and maintenance shell mechanism for heavy-duty omnidirectional AGV robots includes a chassis, a body shell, a lifting mechanism protective shell, a bellows cover, and a lifting plate, which are interconnected from bottom to top to form a cavity. The lifting mechanism protective shell has symmetrically arranged shell maintenance windows on its left and right sides, and each shell maintenance window is provided with a matching shell maintenance window plate. The lifting plate has a lifting plate window, and the lifting plate window is provided with a matching lifting plate window plate. The shell maintenance window plate and the shell maintenance window, as well as the lifting plate window and the lifting plate window plate, are all movably connected by screws.

[0007] Furthermore, the lifting plate has a lifting window plate groove for embedding the lifting plate window plate. The bottom wall of the lifting window plate groove and the lifting plate window plate have corresponding threaded holes, and the screw is screwed into the threaded holes.

[0008] Furthermore, the protective housing of the lifting mechanism is provided with a housing window plate groove for embedding the housing inspection window plate. The bottom wall of the housing window plate groove and the housing inspection window plate are provided with corresponding threaded holes, and the screw is screwed into the threaded holes.

[0009] Furthermore, the lifting plate window includes a first lifting plate window corresponding to the position of the dual differential servo mechanism and a second lifting plate window corresponding to the lead screw lifting mechanism.

[0010] Furthermore, the lifting plate window panel is provided with a window panel anti-slip pad that matches its shape, and the window panel anti-slip pad is connected to the lifting plate window panel by Velcro.

[0011] Furthermore, the anti-slip pad of the window panel is provided with a disassembly hole.

[0012] Furthermore, the surface of the lifting plate is provided with a lifting plate anti-slip pad that matches its shape, and the lifting plate anti-slip pad has a matching window panel anti-slip pad through groove at the position corresponding to the window panel anti-slip pad.

[0013] Furthermore, the anti-slip pad of the lifting plate is connected to the lifting plate with 3M adhesive.

[0014] Furthermore, the shape and size of the casing inspection window plate are adapted to the casing inspection window.

[0015] Furthermore, the shape and size of the lifting plate window panel are adapted to the shape and size of the lifting plate window.

[0016] This utility model provides a convenient disassembly and maintenance shell mechanism for heavy-duty omnidirectional AGV robots. By incorporating a removable maintenance window, internal components can be inspected without completely disassembling the shell, achieving non-destructive maintenance and reducing labor time. The lifting plate and window are equipped with anti-slip pads to prevent material slippage. This design balances component protection and convenient maintenance, improving AGV maintenance efficiency and transport safety. Specific beneficial effects are as follows: 1. Convenient and efficient maintenance: Through the partial disassembly design of the housing maintenance window and the lifting plate window, different internal modules can be directly inspected without disassembling the entire outer shell. This achieves 100% coverage of repeated disassembly and non-destructive maintenance, greatly shortening maintenance time and improving the maintenance efficiency and operational continuity of AGVs.

[0017] 2. Excellent anti-slip performance: The combination of the anti-slip pads on the lifting platform and the anti-slip pads on the window panels significantly increases the friction on the surface of the lifting platform, effectively preventing material slippage and ensuring the safety of heavy object transportation.

[0018] 3. Stable structure and good adaptability: The precise installation of the inspection window panel and the groove, and the secure connection of the screws, ensure the structural stability of the outer shell mechanism; the shape and size of the window panel are perfectly matched with the window, ensuring both protection and smooth maintenance operations.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] like Figure 1 and Figure 2 As shown, this solution provides a housing mechanism for easy disassembly and maintenance of heavy-duty omnidirectional AGV robots, with the specific structure as follows: The chassis 1 provides bottom support for the entire outer shell structure. It is made of high-strength metal to ensure load-bearing strength and serves as the base for the installation of the body shell 2.

[0023] The body shell 2 is connected to the chassis 1 to form the lower outer shell of the AGV, which provides initial protection for the components above the chassis.

[0024] The lifting mechanism protective cover 3 is located above the vehicle body cover 2, with symmetrically arranged maintenance windows 301 on the left and right sides. Each maintenance window 301 is fitted with a maintenance panel 302. To achieve precise installation and secure connection, a panel recess 303 is provided near the maintenance window 301. The maintenance panel 302 is embedded in the recess, and the bottom wall of the recess 303 and the maintenance panel 302 have corresponding threaded holes, which are screwed together and fixed by screws 6. After opening the maintenance panel 302, the power supply module, PDU module, ACU module, wiring harness and other functional modules inside the cavity can be inspected through the maintenance window 301.

[0025] The bellows cover 4 connects the lifting mechanism protective cover 3 and the lifting plate 5. It has a telescopic function and can deform as the lifting plate 5 rises and falls, while also protecting the internal lifting mechanism.

[0026] The lifting plate 5 is a key component for supporting heavy objects. Its surface has lifting plate windows 501, including a first lifting plate window 504 corresponding to the position of the dual differential speed servo mechanism and a second lifting plate window 505 corresponding to the lead screw lifting mechanism. Each lifting plate window 501 is fitted with a lifting plate panel 502. A lifting plate groove 503 is provided on the lifting plate 5 at the position corresponding to the lifting plate window panel 502. The lifting plate window panel 502 is embedded in the groove, and the bottom wall of the groove 503 and the lifting plate window panel 502 have corresponding threaded holes, which are screwed together and fixed by screws 6. After opening the lifting plate window panel 502, the internal electromechanical structures such as the dual differential speed servo mechanism and the lead screw lifting mechanism can be inspected and repaired through the lifting plate window 501.

[0027] like Figure 3 and Figure 4As shown, the anti-slip structure of this solution includes a window panel anti-slip pad 7 and a lift plate anti-slip pad 8. The window panel anti-slip pad 7 matches the shape of the lift plate window panel 502 and is connected to the lift plate window panel 502 by Velcro, which facilitates quick and easy attachment or removal. The window panel anti-slip pad 7 is provided with a removal hole 701, which can be pried up with tools such as an Allen wrench to facilitate its separation from the lift plate window panel 502, thereby facilitating the removal of the lift plate window panel 502.

[0028] The lifting plate anti-slip mat 8 matches the shape of the lifting plate 5 and is connected to the lifting plate 5 with 3M adhesive. A through groove 801 for the window plate anti-slip mat 7 is provided at the corresponding position, without affecting the operation of the window plate anti-slip mat 7. This anti-slip structure effectively increases the friction on the surface of the lifting plate 5, preventing materials from slipping during AGV movement.

[0029] During assembly, first install the body shell 2 onto the chassis 1, then install the lifting mechanism protective cover 3 on top of the body shell 2 (or the lifting mechanism protective cover 3 is connected to the chassis 1 via a bracket, ensuring that it can extend out of the body shell 2), then install the bellows cover 4, and finally install the lifting plate 5 on top of the bellows cover 4.

[0030] When installing the inspection window panel, the housing inspection window panel 302 is embedded into the housing window panel groove 303, and the lifting plate window panel 502 is embedded into the lifting window panel groove 503, and they are fixed by screws 6 respectively.

[0031] When installing the anti-slip mats, attach the lift plate anti-slip mat 8 to the surface of the lift plate 5 using 3M adhesive, and then attach the window panel anti-slip mat 7 to the surface of the lift plate window panel 502 using Velcro, ensuring that the through groove 801 of the window panel anti-slip mat corresponds to the position of the window panel anti-slip mat 7.

[0032] During maintenance, if the power module or similar components need repair, simply unscrew the screws 6 on the access panel 302 and remove the panel. If the dual differential speed servo mechanism or similar components need repair, unscrew the screws 6 on the lifting plate panel 502, separate the anti-slip pad 7 through the disassembly hole 701, and remove the panel for repair. After repair, reassemble in reverse order; this will not affect the normal operation of the AGV.

[0033] The above description is only for illustrating the embodiments of this utility model and is not intended to limit this utility model. For 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.
