Description

Technical Field

[0001] This utility model relates to the field of transportation technology, and in particular to an engine parts transfer vehicle. Background Technology

[0002] During engine assembly, parts need to be transferred between different workstations. This is usually done manually by operators or by using forklifts, which is time-consuming and labor-intensive.

[0003] In some technical solutions, a table or shelf is placed at the assembly station. The shelf is used to support and temporarily store the corresponding parts. However, the parts are not easy to move, which can easily lead to workers relying on the shelf and causing the parts to not be circulated in a timely manner.

[0004] The inventor attempted to add a walking component to facilitate the formation of a transport vehicle in conjunction with the shelving. However, this component transport vehicle still has the following problems:

[0005] (1) In order to ensure the stability of the parts transport vehicle when it is moving, larger and heavier parts such as engine housings are generally placed at the bottom of the transport vehicle. However, their placement is obstructed by the upper rack of the transport vehicle, making it inconvenient to pick up and put them in quickly.

[0006] (2) The transport vehicle's rack can only provide horizontal racks, which are not convenient for limiting the movement of accessories with curved profiles such as camshafts and connecting rod pistons. This can easily cause these accessories to roll or even fall off the rack. Utility Model Content

[0007] This utility model provides an engine parts transfer vehicle, which can solve at least one of the above-mentioned technical problems.

[0008] To address the aforementioned technical problems, one or more embodiments of this utility model provide an engine parts transfer vehicle, comprising a square frame on which multiple layers of support assemblies are mounted sequentially from bottom to top. Each layer of support assembly includes at least one horizontal support plate, and a traveling assembly is provided at the lower part of the frame. Support sub-components are detachably mounted on the outer contour of each layer of support assembly, with at least a portion of the outer contour of the support sub-component matching the outer contour of the part to be supported. The support sub-components protrude laterally from the frame. A sliding plate is mounted on the bottommost support assembly, allowing it to slide horizontally relative to the support assembly. A locking element is provided between the sliding plate and the support assembly. A rotatable and positioning support wheel assembly is provided at the end of the sliding plate, capable of rotating relative to the sliding plate to either be vertically upward and disengaged from the ground or vertically downward and in contact with the ground.

[0009] The beneficial effects of one or more of the above technical solutions are as follows:

[0010] In this design, each layer of the support assembly has a detachable support sub-component installed on its outer contour. At least part of the sub-component's outer contour is the same as the outer contour of the accessory to be supported, and the support sub-component protrudes laterally from the frame. This arrangement facilitates the placement of support positions for components such as camshafts and piston rods on the outside of the support assembly using detachable support sub-components, preventing them from rolling or falling out of the support assembly.

[0011] In this design, the skateboard can slide horizontally relative to the support assembly. The end of the skateboard has a rotatable support wheel assembly that can rotate relative to the skateboard to either vertically upward or downward and be positioned there. This allows the skateboard to be used to store larger and heavier components. When it's necessary to retrieve or place these items, the skateboard slides out from the bottom of the frame, and the vertically downward-facing support wheel assembly provides support for the skateboard. At this point, other support assemblies above the skateboard will not obstruct the retrieval or placement of large components.

[0012] In addition, during transport, the skateboard can be slid into the frame, reducing the space occupied by the transport vehicle and improving its mobility in the work area. Attached image description:

[0018] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0019] See Figures 1-4This embodiment provides an engine parts transfer vehicle, including a square frame 1. Multiple support assemblies are mounted on the frame 1, arranged sequentially from bottom to top. Each support assembly includes at least one horizontal support plate 3. A traveling assembly 17 is provided at the lower part of the frame 1. Support sub-components 4 are detachably mounted on the outer contour of each support assembly. At least a portion of the outer contour of the support sub-component 4 is the same as the outer contour of the part to be supported, and the support sub-component 4 protrudes laterally from the frame 1. A sliding plate 5 is mounted on the bottom support assembly. The sliding plate 5 can slide horizontally relative to the support assembly. A locking element is provided between the sliding plate 5 and the support assembly. A rotatable and positioning support wheel assembly 6 is provided at the end of the sliding plate 5. The support wheel assembly 6 can rotate relative to the sliding plate 5 to face vertically upwards and disengage from the ground, or face vertically downwards and contact the ground to support the sliding plate 5.

[0020] Specifically, the outer contour of the square frame 1 here is a cuboid shape, which serves as the supporting skeleton of the entire transport vehicle. The supporting plate 3, the walking component 17, and the supporting sub-components 4 in the supporting assembly are all supported and fixed through this frame 1.

[0021] As one specific structural form, the support plates 3 in the multi-layer support assembly have their vertical projections overlapping, and the gravity borne by each support assembly is transmitted to the bottom of the entire transfer vehicle through the frame 1.

[0022] In this embodiment, the frame 1 includes multiple beams 2 that are perpendicular to each other, and the outer surface of each beam 2 has a limiting groove 201 along its own extension direction. Adjacent beams 2 and support sub-components 4 are fixed together by angle irons 7, bolts 8 and nuts 9 provided in the limiting grooves 201.

[0023] Specifically, beam 2 here is divided into horizontal beams and longitudinal beams extending horizontally, and also includes vertical beams extending vertically. The horizontal beams and longitudinal beams enclose a horizontal installation space, which facilitates the fixing of support plates 3 within this installation space. Support plates 3 can be overlapped so that their four sides are respectively supported by adjacent horizontal or longitudinal beams. The support plates 3 can also be connected to the horizontal and longitudinal beams by adhesive or the aforementioned bolts 8. More specifically, multiple reinforcing beams can be provided on the lower surface of each support plate 3, and the two ends of these reinforcing beams are fixed to adjacent horizontal or longitudinal beams.

[0024] As a specific structural arrangement, frame 1 has a height of 130cm, a length of 130cm, and a width of 80cm. The height difference between adjacent support plates 3 is 43cm, and the interval between two adjacent reinforcing beams is 40cm. In addition, beam 2 has a square cross-section of 4cm×4cm, and support plate 3 has a thickness of 2cm.

[0025] In this embodiment, the beam 2 has a square cross-section, and each of the four outer sides of the beam 2 is provided with a limiting groove 201. The limiting groove 201 extends through both end faces of the beam 2 along its extension direction. The limiting groove 201 includes a first groove 202 and a second groove 203 arranged sequentially from the side of the beam 2 inward. The opening size of the first groove 202 is smaller than that of the second groove 203. The cross-section of the second groove 203 is semi-circular or square.

[0026] As another structural form, the cross-section of the first groove 202 and the second groove 203 can also be square, which will not be elaborated here.

[0027] In this embodiment, one of the support plate 3 and the slide plate 5 of the lowest support component is provided with a slide rail, and the other is provided with a slide groove that cooperates with the slide rail.

[0028] Specifically, a sliding plate 5 is installed at the bottommost support assembly. The lower surface of the sliding plate 5 is in contact with the upper surface of the bottommost support plate 3 to support the sliding plate 5. In this embodiment, taking the longitudinal beam as being longer than the transverse beam as an example, the sliding plate 5 can slide along the extension direction of the longitudinal beam, allowing it to slide into or out of the frame 1. The extension direction of the slide rail and the slide groove is the same as the extension direction of the longitudinal beam. To prevent the sliding plate 5 from vertically separating from the support plate 3, the slide groove can be a T-shaped groove or a dovetail groove, and the cross-sectional shape of the slide rail can be adapted accordingly.

[0029] In this embodiment, the support component 4 includes, but is not limited to, one or more of the crankshaft support, camshaft support, and piston connecting rod support.

[0030] As a specific structural form, multiple horizontal first extension beams 13 are set on the outside of the frame 1. The support component 4 has a vertically set support plate 11. The lower end of the support plate 11 is fixed to the first extension beams 13, and the upper end of the support plate 11 has an arc-shaped notch. The arc-shaped notch is used to fit the outer circumference of the component to be supported, and an elastic pad 12 is covered at the arc-shaped notch. The cooperation of multiple support plates 11 can realize the support of the crankshaft or camshaft.

[0031] Additionally, the support component includes a insert plate 15: multiple pairs of second extension beams 14 are arranged side-by-side on the outer side of the frame 1, forming an insertion space between two second extension beams 14. Slots are respectively provided on the opposite sides of the two second extension beams 14. The aforementioned horizontal insert plate 15 is detachably installed in the insertion space. The insert plate 15 has a vertical through hole, the size of which is set to allow the piston rod to pass through while restricting the piston from passing through. Thus, in this embodiment, the second extension beams 14 and the insert plate 15 are used to temporarily store the piston rod.

[0032] Specifically, a tappet connector 16 is also installed on the outside of the frame 1 for connecting tappets in the temporary storage engine.

[0033] In this embodiment, the spacing between adjacent layer support components can be adjusted and fixed.

[0034] Specifically, the nut 9 is placed in the second groove 203 of the beam 2, and the bolt 8 passes through the angle iron 7 and connects to the nut 9. The portion of the bolt 8 between the angle iron 7 and the nut 9 passes through the first groove 202 of the limiting groove 201 at the end of the beam 2. After the angle iron 7 is slid into place, the bolt 8 and the nut 9 are tightened.

[0035] In this embodiment, the walking component 17 includes casters located at the four corners of the frame 1, and the support wheel assembly 6 includes casters. And / or, the walking component 17 and the support wheel assembly 6 are electric wheels.

[0036] Specifically, the support wheel assembly 6 includes a wheel body and a bracket. The bracket is rotatably connected to the end of the slide plate 5 via a pivot 502. Two first pin holes are provided on the slide plate 5, and a second pin hole is provided on the bracket. A positioning pin 501 passes through the second pin hole. When the support wheel assembly 6 rotates to a position where the wheel body faces downwards, the second pin hole aligns with one of the first pin holes, and the positioning pin is inserted. When the support wheel assembly 6 rotates to a position where the wheel body faces upwards, the second pin hole aligns with the other first pin hole, and the positioning pin is inserted.

[0037] Working principle: When using this device, support sub-components 4 are installed on the support assemblies of different layers on the side of frame 1 as needed. Different parts in the engine assembly process are placed on different layers of the transport vehicle. Among them, parts that are easy to roll are placed on support sub-components 4, and parts that are not easy to roll are placed on support plates 3. Larger and heavier parts are placed on the sliding plate 5 of the bottom support assembly of frame 1.

[0038] When you need to retrieve accessories from the bottom skateboard 5, first slide skateboard 5 outward a short distance, then rotate the support wheel assembly 6 on skateboard 5 so that the support wheels are facing down and in position. At this time, skateboard 5 is supported by both the support wheel assembly 6 and the support plate 3. Continue to pull skateboard 5 so that most of the skateboard 5 is detached from the frame 1, and then you can retrieve or place the accessories.

[0039] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0040] Any aspects of this utility model not described in detail are known to those skilled in the art.
