Description

Technical Field

[0001] This invention relates to the field of transfer technology, and in particular to a rocker arm assembly transfer vehicle. Background Technology

[0002] The rocker arm assembly, as an important component of the engine's valve train, is one of the engine's key parts. The rocker arm assembly includes the rocker arm, rocker arm shaft, rocker arm seat, spring, etc. Due to its irregular shape, it is not easy to stack during transportation. At the same time, as a key component of the engine, it has high requirements for cleanliness. Therefore, the placement and dust protection of the rocker arm assembly during transportation are relatively strict.

[0003] Existing technologies include several transfer vehicles, such as an automotive parts transfer vehicle. This vehicle includes a support plate with a parts fixing device mounted on it. The parts fixing device includes a main fixing rod with inclined support rods on both sides, and support blocks on the support rods. This solution uses the inclined support rods and blocks to limit the movement of automotive parts. However, since the rocker arm assembly mainly consists of a rocker arm shaft and a rocker arm, while the support blocks and support rods can block the rocker arm shaft, they cannot guarantee the stability of the rocker arm assembly during transfer. Another example is a transfer vehicle for irregularly shaped parts, which includes a frame, a mounting plate, and a perforated back plate. The mounting plate is equipped with parts suspension columns and parts protection columns. This solution is a suspension-based transfer vehicle and is also unsuitable for transferring rocker arm assemblies. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a rocker arm assembly transfer vehicle. The rocker arm rotating frame can rotate relative to the vehicle frame, allowing each mounting surface to be vertically placed with rocker arm assemblies. This increases the number of rocker arm assemblies that can be placed per unit volume and improves the space utilization rate of the rocker arms during placement and transportation.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: An embodiment of the present invention provides a rocker arm assembly transfer vehicle, including a vehicle frame, a plurality of rocker arm rotating frames are installed in the vehicle frame, and the rocker arm rotating frames are rotatably connected to the vehicle frame; the rocker arm rotating frames have multiple mounting surfaces, and each mounting surface is provided with multiple sets of hanging components in sequence along the vertical direction, the hanging components being used to support the rocker arm assembly.

[0006] As a further implementation, the rocker arm rotating frame includes two parallel support frames connected by multiple sets of columns, with each set of columns forming an mounting surface for a hanging component.

[0007] As a further implementation, the support frame is a rectangular structure, forming four mounting surfaces.

[0008] As a further implementation, the mounting component includes at least two mounting parts.

[0009] As a further implementation, the hook-shaped part is a hook-shaped structure.

[0010] As a further implementation, the rocker arm rotating frame is equipped with a rotation locking mechanism, which is used to keep the rocker arm rotating frame stationary when the rocker arm assembly is picked up or placed down. As a further implementation, the rotary locking mechanism includes a turntable and a pin, with multiple openings on the circumference of the turntable; The pin is located on one side of the turntable and is connected to a spring so that the pin is inserted into the opening when the turntable rotates to the position corresponding to the opening.

[0011] As a further implementation, the pin is arranged radially along the turntable, and the spring is installed inside the sleeve.

[0012] As a further implementation, a dust cover is installed on the outside of the vehicle frame, and at least one side of the dust cover can be opened; The dust cover is equipped with a magnetic strip on its openable side; As a further implementation, a hanger is installed at one end of the vehicle frame and a hook is installed at the other end.

[0013] The beneficial effects of this invention are as follows: (1) The transfer vehicle of the present invention has a rocker arm rotating frame installed in its body frame. The rocker arm rotating frame has multiple mounting surfaces. Each mounting surface is arranged with multiple sets of hanging components in sequence along the vertical direction. The rocker arm assembly is stably supported by the hanging components. At the same time, the rocker arm rotating frame can rotate relative to the body frame, so that the rocker arm assembly can be placed vertically on each mounting surface, increasing the number of rocker arm assemblies that can be placed in a unit volume and improving the space utilization rate of the rocker arm during placement and transportation.

[0014] (2) Multiple rocker arm rotating frames are installed in the vehicle frame of the present invention. Adjacent rocker arm rotating frames will not interfere with each other. At the same time, each rocker arm rotating frame can realize multi-layer and multi-face rocker arm assembly arrangement, which increases the capacity of the transfer vehicle. By rotating the rocker arm rotating frame, rocker arm assemblies can be placed on different mounting surfaces, which is convenient to operate. Furthermore, multiple transfer vehicles can be connected together for simultaneous transfer, further increasing the transfer volume.

[0015] (3) The rocker arm rotating frame of the present invention is composed of a multi-faceted three-dimensional structure consisting of a support frame and a column. Each mounting surface is provided with multiple layers of hanging components, and each set of hanging components includes at least two hanging parts to achieve stable support for the rocker arm assembly.

[0016] (4) The support frame of the present invention is equipped with a dust cover, which can be easily opened or closed, and can play a good dust prevention role during transportation.

Detailed Implementation

[0020] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0021] For ease of description, the words "front," "rear," "left," and "right" appearing in this invention only indicate that they are consistent with the front, rear, left, and right directions of the accompanying drawings themselves, and do not limit the structure. They are merely for the purpose of facilitating the description of this invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Example 1: The rocker arm assembly includes the rocker arm, rocker arm shaft, etc. Due to its irregular shape, it is difficult to stack during transport. Existing component transport vehicles are generally not suitable for transporting rocker arm assemblies. Therefore, this embodiment provides a rocker arm assembly transport vehicle, such as... Figures 1-3As shown, it includes a vehicle frame 1, a rocker arm rotating frame 2, a dust cover 4, etc. The bottom of the vehicle frame 1 is equipped with casters with locking function. In this embodiment, the front end of the vehicle frame 1 is equipped with swivel casters 5 to facilitate the turning of the transfer vehicle during movement. The rear end of the vehicle frame 1 is equipped with directional casters 6 to ensure the stability of the transfer vehicle when it is stopped.

[0023] A hanger 7 is installed at the front end of the vehicle frame 1, and a hook 8 is installed at the rear end. Both the hanger 7 and the hook 8 are located in the middle of the vehicle frame 1. Adjacent transfer vehicles are connected through the cooperation of the hanger 7 and the hook 8, enabling the coordination of multiple transfer vehicles, which can effectively increase the number of transfers per trip and improve transfer efficiency. In this embodiment, the hook 8 adopts a pin structure. When it is necessary to connect with the hanger 7 of another transfer vehicle, the pin is pulled out, and after the hanger 7 is in place, the pin is inserted back to complete the connection.

[0024] The left and right sides of the vehicle frame 1 are symmetrically equipped with forklift mounting holes 9, which serve as the forklift's handling interface, accommodating different transfer methods, facilitating rapid forklift turnover, and further improving flexibility. For example... Figure 2 As shown, the front and rear ends of the vehicle frame 1 are also equipped with push handles 11. The push handles 11 can be set at the middle position in the height direction of the vehicle frame 1, or can be adjusted adaptively. The push handles 11 are made of bent steel pipes, which facilitates the adjustment of the position of the transfer vehicle.

[0025] In this embodiment, the vehicle frame 1 is a cuboid structure, welded from multiple square steel pipes; a bottom plate 10 is installed at the bottom of the vehicle frame 1, and a top plate 16 is installed at the top. The top plate 16 and the bottom plate 10 can be made of galvanized sheet. The vehicle frame 1 is sealed around its perimeter by a dust cover 4 to ensure the sealing during transport and the cleanliness of the rocker arm assembly.

[0026] The dust cover 4 is made of PVC and wraps around the outside of the vehicle frame 1. The dust cover 4 includes multiple dustproof panels. The dustproof panels located at the front and rear ends of the vehicle frame 1 are fixedly connected to the vehicle frame 1. The dustproof panels on the left and right sides of the vehicle frame 1 can be opened to facilitate the placement and removal of the rocker arm assembly. The dustproof panels can be opened upwards or sideways. In this embodiment, the top of the dustproof panel is rotatably connected to the vehicle frame 1, and the other three sides are magnetically attached to the vehicle frame 1. This ensures the overall dustproof performance of the transport vehicle while allowing the dustproof panels to quickly attach to the vehicle frame 1, improving the efficiency of opening and closing.

[0027] It is understood that in other embodiments, the vehicle frame 1 may also adopt other structural forms; the dustproof plate and the vehicle frame 1 may adopt other openable methods, such as snap-fit.

[0028] like Figure 2 and Figure 3As shown, one or more rocker arm rotating frames 2 are installed inside the vehicle frame 1, depending on the transfer capacity of the rocker arm assembly. Adjacent rocker arm rotating frames 2 are spaced apart along the front and rear directions of the vehicle frame 1 to avoid interference when adjacent rocker arm rotating frames 2 rotate.

[0029] This embodiment uses two rocker arm rotating frames 2 as an example for detailed description. The two rocker arm rotating frames 2 are rotatably installed inside the vehicle frame 1 and can be rotated manually or automatically; the rocker arm rotating frames 2 can rotate 360°. When the rocker arm rotating frames 2 rotate automatically, they are driven by a rotation drive mechanism. The rotation drive mechanism can be installed at the bottom or top of the vehicle frame 1. Considering the stability of the overall structure, in this embodiment, the rotation drive mechanism is installed on the base plate 10 of the vehicle frame 1, that is, the top and bottom ends of the rocker arm rotating frames 2 are rotatably connected to the vehicle frame 1, and the bottom end of the rocker arm rotating frames 2 is connected to the rotation drive mechanism. The rotation drive mechanism can be a motor-driven sprocket and chain mechanism, gear set, gear and rack mechanism, etc., as long as it can provide rotational power.

[0030] Furthermore, rotating shafts 15 are respectively installed at the top and bottom of the rocker arm rotating frame 2, and the rotating shafts 15 are connected to the vehicle frame 1 through bearings. Figure 2 As shown, the rocker arm rotating frame 2 is a vertical structure with multiple mounting surfaces. In this embodiment, the rocker arm rotating frame 2 has four mounting surfaces, forming a cuboid frame structure. Of course, in other embodiments, the rocker arm rotating frame 2 can have more than four mounting surfaces, as long as the rocker arm assemblies on adjacent mounting surfaces do not interfere with each other when placed.

[0031] Furthermore, the rocker arm rotating frame 2 includes a support frame 12 and columns 13. The two support frames 12 are parallel to each other and connected by multiple sets of columns 13. When the support frame 12 is a rectangular frame, each corresponding side of the support frame 12 is connected by at least two columns 13. Multiple columns 13 corresponding to the same mounting surface form a group to ensure the support performance of the rocker arm rotating frame 2. In this embodiment, both the support frame 12 and the columns 13 are made of square tubing.

[0032] Each mounting surface is equipped with a mounting assembly. Multiple mounting assemblies are evenly spaced along the vertical height of the rocker arm rotating frame 2, forming a multi-layer mounting assembly. Each layer can hold one rocker arm assembly. By using each mounting surface and a multi-layer arrangement, the rocker arm assembly capacity of each rocker arm rotating frame 2 is increased. The spacing between adjacent groups of mounting assemblies ensures smooth placement of the rocker arm assemblies.

[0033] In this embodiment, the mounting assembly includes at least two mounting parts 14. The number of mounting parts 14 in each mounting assembly is the same as the number of posts 13. The mounting parts 14 are welded and fixed to the posts 13. Figure 2 and Figure 3As shown, the hook-type part 14 has a hook-shaped structure with a limiting hook at its end. The opening of the limiting hook faces upward, and the rocker arm shaft in the rocker arm assembly cooperates with the limiting hook. The installation positions of the same set of hook-type parts 14 are on the same horizontal line to stably support the rocker arm assembly. To prevent the rocker arm assembly from colliding with the hook-type part 14 during placement and transportation, a rubber edging is provided at the opening of the limiting hook.

[0034] A rotation locking mechanism 3 is installed at the bottom of the rocker arm rotating frame 2 to keep the rocker arm rotating frame 2 stationary when picking up or placing the rocker arm assembly, preventing the placement of the rocker arm assembly from being affected by the rotation of the rocker arm rotating frame 2. In this embodiment, as... Figure 4 As shown, the rotary locking mechanism 3 includes a turntable 17, a pin 19, and a spring 20. The turntable 17 is installed on the outside of the bottom shaft 15 of the rocker arm rotating frame 2. The turntable 17 has an opening 18 set according to a 90-degree pitch circle to accommodate four mounting surfaces.

[0035] A pin 19 is located on one side of the turntable 17 and is arranged radially along the turntable 17. One end of the pin 19 has a tapered end, which faces the side where the turntable 17 is located. The other end of the pin 19 is installed in the sleeve 21 by a spring 20. When the rocker arm rotating frame 2 rotates and approaches the stop position (the position where the opening 18 is located), the pin 19 enters the opening 18 under the left and right pressure of the spring 20, automatically locking itself and achieving a blind insertion locking function. In this embodiment, the opening 18 is a V-shaped opening.

[0036] It should be noted that the transfer vehicle can be automatically locked using the rotary locking mechanism 3 when it is at the workstation, which can reduce workload and improve efficiency; however, during the transport of the transfer vehicle, in order to ensure locking safety, it is still necessary to manually operate the pin structure installed on the bottom support frame 12 to lock it with the bottom plate 10 of the vehicle frame 1. The pin structure here is existing technology, so it will not be described in detail.

[0037] The usage process of the rocker arm assembly transfer vehicle in this embodiment is as follows: Open one side of the dust cover 4 and place the rocker arm assemblies (which have already been unpacked) flat on the mounting surface of the rocker arm rotating frame 2 corresponding to the opening side of the dust cover 4. After all the mounting components on the mounting surface are filled with rocker arm assemblies, open the locking mechanism, rotate the rocker arm rotating frame 2 so that the adjacent mounting surfaces are aligned with the opening side of the dust cover 4, lock the rotating rocker arm rotating frame 2, and continue placing the rocker arm assemblies until all mounting surfaces are filled.

[0038] Next, attach the magnetic strip of the dustproof plate to the vehicle frame 1; then, transfer the vehicle by single vehicle or multiple vehicles, forklift, or tow as required.

[0039] After being transferred to the designated workstation, the dust cover 4 is opened, and the rocker arm assembly is taken out one by one.

[0040] The transport vehicle of this embodiment is specifically designed for rocker arm assemblies. Multiple hook-shaped attachments 14 collectively support the rocker arm assembly. The limiting hooks of the attachments 14 engage well with the rocker arm shaft, preventing swaying of the rocker arm assembly during transport. This embodiment also utilizes a rotatable rocker arm rotating frame 2 within the vehicle frame 1 to achieve vertical placement of the rocker arm assembly, increasing the number of rocker arm assemblies that can be placed per unit volume and improving space utilization during placement and transportation.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
