Description

Technical Field

[0001] This utility model relates to the field of in-plant parts transfer technology, specifically a new type of in-plant transfer vehicle for differentials. Background Technology

[0002] As a precision component in a forklift transmission system, the differential requires strict protection against impacts and contamination during in-plant transport. Currently, wooden pallets are commonly used in the industry for transporting differentials. However, existing wooden pallets have the following drawbacks: First, wooden pallets lack a dedicated positioning structure, making the differential prone to displacement and collisions after placement, resulting in scratches on the surface of the parts or damage to the internal structure; second, the surface of wooden pallets easily generates sawdust, which can contaminate the differential; third, wooden pallets have a single-layer structure, resulting in low space utilization and limited single-transfer capacity, making it difficult to meet the transport needs of high-efficiency production. Utility Model Content

[0003] The purpose of this utility model is to provide a new type of in-plant transfer vehicle for differentials, so as to solve the problems of poor anti-collision effect, easy contamination and low space utilization when transporting differentials with wooden pallets.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A novel in-plant transfer vehicle for differentials includes a vehicle body, a lower pallet, and an upper pallet. The lower pallet is fixedly installed inside the lower end of the vehicle body, and uprights are fixedly installed at the four corners of the lower pallet. The upper pallet is located above the lower pallet, with one end hinged to the vehicle body and the other end floating. The upper pallet has two modes: closed and open. In the closed mode, the upper pallet is parallel to the lower pallet, and the floating end of the upper pallet rests on the uprights. In the open mode, the upper pallet flips to be perpendicular to the lower pallet and is fixedly connected to the vehicle body. Both the lower and upper pallets are fixedly equipped with several positioning blocks.

[0005] Furthermore, the vehicle body includes a chassis, with universal wheels fixedly installed at the bottom of the four corners of the chassis, side frames fixedly installed at both ends of the chassis, a first ear plate fixedly installed in the middle of one side of the side frame, the first ear plate having a through hole in the middle, and a second ear plate fixedly installed above the first ear plate in any side frame, the second ear plate having a through hole in the middle.

[0006] Furthermore, the upper pallet includes an upper pallet frame, with third ear plates fixedly provided at both ends of the upper pallet frame. The third ear plate has a through hole in the middle, and the third ear plate is aligned with the first ear plate and hinged by a pin. A pin hole is provided on one side of the upper pallet frame. When the upper pallet is in the open mode, a pin is inserted into the pin hole through the second ear plate to fix the upper pallet to the vehicle body.

[0007] Furthermore, a number of upper mounting blocks of varying lengths are fixedly installed inside the upper tray frame. The upper mounting blocks are arranged obliquely and equidistantly, and positioning blocks are fixedly installed on the upper mounting blocks.

[0008] Furthermore, the lower tray includes a lower tray frame, and a plurality of lower mounting blocks of different lengths are fixedly disposed within the lower tray frame. The lower mounting blocks are arranged obliquely and equidistantly, and positioning blocks are fixedly disposed on the lower mounting blocks.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes an upper and lower tray on the vehicle body to accommodate the differential in two layers, improving space utilization and significantly increasing the amount of differential that can be transported at one time. The upper tray is hinged to the vehicle body and can be flipped up and down, facilitating the placement of the differential on the lower tray. Both the upper and lower trays are equipped with positioning blocks to support the differential, preventing displacement after placement and avoiding collisions between the differential and the vehicle body or other differential components. The positioning blocks are made of plastic to prevent scratching the differential. Attached Figure Description

Detailed Implementation

[0011] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0012] Please see Figures 1 to 7 One embodiment provided by this utility model: A novel in-plant transport vehicle for differentials includes a vehicle body 1, a lower pallet 2, and an upper pallet 3. The lower pallet 2 is fixedly installed inside the lower end of the vehicle body 1, and uprights 202 are welded to the four corners of the lower pallet 2. The upper pallet 3 is located above the lower pallet 2, with one end of the upper pallet 3 hinged to the vehicle body 1 and the other end floating. The upper pallet 3 has two modes: closed and open. In the closed mode, the upper pallet 3 is parallel to the lower pallet 2, and the floating end of the upper pallet 3 rests on the uprights 202. In the open mode, the upper pallet 3 flips to be perpendicular to the lower pallet 2 and is fixedly connected to the vehicle body 1, facilitating the placement of the differential 5 on the lower pallet 2. Both the lower pallet 2 and the upper pallet 3 are fixedly equipped with several positioning blocks 4.

[0013] The vehicle body 1 includes a base frame 101. Universal wheels 105 are fixedly installed at the bottom of the four corners of the base frame 101. Side frames 102 are welded to both ends of the base frame 101. A first ear plate 103 is welded to the middle of one side of the side frame 102. A through hole is opened in the middle of the first ear plate 103. A second ear plate 104 is welded to either side frame 102 above the first ear plate 103. A through hole is opened in the middle of the second ear plate 104.

[0014] The upper tray 3 includes an upper tray frame 301. Third ear plates 302 are welded to both ends of the upper tray frame 301. A through hole is opened in the middle of the third ear plate 302. The third ear plate 302 is aligned with the first ear plate 103 and is hinged by a pin, so that the upper tray 3 can rotate around the pin axis. A pin hole 304 is opened on one side of the upper tray frame 301. When the upper tray 3 is in the open mode, a pin is inserted into the pin hole 304 through the second ear plate 104 to fix the upper tray 3 to the vehicle body 1.

[0015] Several upper mounting blocks 303 of varying lengths are fixedly installed inside the upper pallet frame 301. The upper mounting blocks 303 are arranged diagonally and equidistantly, and their spacing is determined according to the size of the differential 5. Positioning blocks 4 are fixedly installed on the upper mounting blocks 303 to fix and support the differential 5. The positioning blocks 4 are made of plastic to avoid scratching the differential 5. Two parallel and adjacent positioning blocks 4 can support one differential 5. The purpose of the diagonal arrangement of the upper mounting blocks 303 is to make reasonable use of the space of the upper pallet frame 301 and maximize the number of differentials 5 that can be placed.

[0016] The lower tray 2 includes a lower tray frame 201, within which several lower mounting blocks 203 of varying lengths are fixedly installed. The lower mounting blocks 203 are arranged obliquely and equidistantly, and positioning blocks 4 are fixedly installed on each lower mounting block 203. The lower tray frame 201 has the same structural size as the upper tray frame 301, and the arrangement of the lower mounting blocks 203 and their positioning blocks 4 is also the same as that of the upper tray 3.

[0017] In use, the upper tray 3 is first flipped upwards and the pin is inserted into the second ear plate 104 and pin hole 304 to fix the upper tray 3 in the open position. The differential 5 is then placed on the lower tray 2. After it is full, the pin is pulled out and the upper tray 3 is flipped down to the closed position. The differential 5 is then placed on the upper tray 3 again until it is full. When retrieving parts, they are first taken from the upper tray 3. After taking them, the upper tray 3 is flipped up and then taken from the lower tray 2.
