Description

Technical Field

[0001] This utility model relates to a carrier used on a power line to transport product components, and in particular to a carrier frame on the carrier for fixing the components. Background Technology

[0002] The products to be manufactured are usually composed of multiple components. Some products have a large number of components. To achieve mass production, a power line is usually required. The product components are loaded into a carrier, and the power line transports the components to the corresponding workstations to complete the various processes of the product. However, some product components have large structural differences and are relatively fragmented, making them inconvenient to transport using ordinary carriers.

[0003] Chinese patent document (publication number: CN219468781U) discloses a conveying device for an assembly line, including a driven component, a frame disposed above the driven component, and a loading device disposed on the frame. The driven component comprises a pulley assembly connected below the frame, a connecting block connected below the pulley assembly, and a drive block rotatably connected to the connecting block. A drive rail is provided below the drive block, and the drive rail has protrusions. When the drive block abuts against the protrusions, the drive rail drives the driven component forward. This invention allows for smooth material flow, improves material conveying and storage efficiency, and maximizes the storage of materials in limited space.

[0004] This conveying device discloses a carrier whose structure includes a carrier frame and a container housing with a cavity on the frame for transporting product components. This cavity-type carrier has a relatively high overall height, which makes its stability during operation relatively poor. When components are offset within the container housing, the carrier is prone to tipping over during track changes. Therefore, this conveying device requires a relatively slow operating speed for the power line, which affects the efficiency of component transport. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a power line carrier frame for fixing the load in the carrier, so that the carrier has good stability during operation.

[0006] To solve the aforementioned technical problem, the present invention provides the following technical solution: a power line carrier frame, comprising two separate connecting structures located on the bottom side, a front force-bearing rod movably provided on the front connecting structure, and a rear force-bearing rod movably provided on the rear connecting structure; vertically arranged load-bearing rollers are provided on the connecting structures; the upper end of the carrier frame forms an mounting surface for mounting the carrier body; the two connecting structures are pivotally connected to the middle position of the lower surface of the two connecting bodies, and the two connecting bodies are arranged side by side and separated; a horizontally arranged counterweight plate connects the two connecting bodies together, and the density of the counterweight plate is greater than the density of the connecting bodies; the mounting surface is mainly composed of the upper surface of the counterweight plate.

[0007] Counterweight plates are typically made of metal materials such as iron or aluminum plates, while the connecting bodies and structures are generally made of plastic. Comparatively, counterweight plates are heavier. The mounting surface on the vehicle frame is used to fit and support the vehicle body, which is also generally made of plastic. The counterweight plate has a relatively large area, while the upper surface of the connecting body contributes little to the area of ​​the mounting surface. The upper surface of the counterweight plate accounts for a large proportion of the mounting surface, typically exceeding 70%. This results in a relatively heavy counterweight plate that, while meeting the installation requirements of the vehicle body, is also heavy enough to lower the overall center of gravity of the vehicle.

[0008] Furthermore, a connecting ring extending downwards is provided on the lower surface of the connecting body, and a pivot inserted into the connecting ring is provided at the upper end of the connecting structure. A limiting port and a limiting body with clearance fit are provided between the pivot and the connecting ring. The mutually cooperating limiting port and limiting body limit the relative deflection angle between the connecting structure and the connecting body. The positions of the limiting port and the limiting body can be interchanged. The deflection angle of the connecting structure relative to the connecting body is limited by the circumferential dimension design of the limiting port, so as to take into account both the normal travel and track changing requirements of the vehicle.

[0009] Furthermore, the connecting bolts that penetrate the connecting body connect the pivot to the connecting body, with a clearance fit between the connecting bolts and the connecting body. The connecting bolts are typically threaded onto the pivot, and the connection between the connecting body and the connecting structure is achieved through the connecting bolts, resulting in good connection stability.

[0010] Furthermore, a metal sleeve is fitted onto the upper end of the connecting bolt with a clearance, and the metal sleeve is embedded in the connecting body. When the connecting structure rotates relative to the connecting body, sliding friction is generated between the metal sleeve and the connecting bolt. The resulting frictional force is small and has good wear resistance, thus making the connecting structure rotate flexibly. The metal sleeve is generally made of copper or stainless steel.

[0011] Furthermore, a hollow insert is integrally formed on the lower surface of the connector within the connecting ring. The insert is coaxially and loosely inserted into the pivot, and the connecting bolt is loosely inserted into the insert. This clearance fit between the insert and the pivot further improves the radial stability of the connector and the connecting structure in the connecting bolt direction.

[0012] Furthermore, the upper surface of the counterweight plate is flush with the upper surface of the connecting body. They form a uniform mounting surface at the upper end of the carrier frame, which is beneficial for the stable connection and fixation of the carrier body.

[0013] Furthermore, the connecting body is provided with a connecting tongue and groove, and the end of the counterweight plate is embedded in the connecting tongue and groove. The connecting tongue and groove facilitates the formation of a uniform and complete mounting surface at the upper end of the carrier frame, and also effectively ensures the firmness of the connection between the counterweight plate and the connecting body.

[0014] Furthermore, a hollow connecting post protrudes from the bottom surface of the connecting tongue and groove, and a clearance opening is provided on the counterweight plate, with the connecting post located at the clearance opening. The presence of the connecting post facilitates the secure installation of the load-bearing structure.

[0015] Furthermore, the connecting structure is equipped with a positioning wheel, which is vertically positioned. The positioning wheel is located below the load-bearing roller, and there is a gap between the positioning wheel and the load-bearing roller. By setting the positioning wheel, combined with the limiting plate set on the power line track, which extends into the gap, the stability of the vehicle's movement on the track can be well guaranteed.

[0016] Compared with existing technologies, this utility model has the following advantages: A high-density counterweight plate is installed on the carrier frame, and the counterweight plate is relatively large, giving it a certain weight. This lowers the center of gravity of the carrier, effectively improving its stability during operation. Because the center of gravity is effectively lowered, the placement of product components inside the carrier does not require strict adherence to positioning specifications, increasing the loading speed. Furthermore, the improved stability of the carrier allows for a suitable increase in its operating speed on the power line, further enhancing the efficiency of the power line.

Detailed Implementation

[0024] Referring to the accompanying drawings, this power line carrier frame, as part of a vehicle, is used to mount and fix a specific body with an open cavity, thus forming a complete vehicle. The structure includes two separate connecting structures 4 located on the bottom side; each connecting structure 4 is a block-shaped body. Figure 1 , 2 As shown in Figure 3, one type of connection structure 4 is a hexagonal prism; another type of connection structure 4 is as follows: Figure 5 , 6 The structure is shown as a quadrangular prism. Both types of connecting structures 4 have mounting openings at their lower corners. In a vehicle, a front force-bearing rod 7 is movably mounted in the mounting opening of the front connecting structure 4; a rear force-bearing rod 2 is movably mounted in the mounting opening of the rear connecting structure 4. The terms "front" and "rear" are based on the vehicle's direction of travel. Normally, the front force-bearing rod 7 receives power from the power line, enabling the vehicle to move on the main rail and support rail. The rear force-bearing rod 2 only receives power from the power line when the vehicle changes tracks, thus facilitating smooth track changes. These are all existing technologies. Vertically mounted load-bearing rollers 3 are provided on the connecting structure 4. When the vehicle runs on the power line, it relies on the load-bearing rollers 3 rolling forward on the track.

[0025] The upper end of the vehicle frame has a mounting surface, which is generally flat, and the vehicle body is fitted onto the mounting surface. In addition to the two connecting structures 4 mentioned above, the vehicle frame also includes two long, strip-shaped connecting bodies 8. The two connecting structures 4 are pivotally connected to the middle of the lower surface of the two connecting bodies 8, and the two connecting bodies 8 are arranged side-by-side. A horizontally arranged counterweight plate 1 connects the two connecting bodies 8 together, with the two connecting bodies 8 located at both ends along the length of the counterweight plate 1. As shown in the figure, the length of the connecting body 8 can be slightly greater than the width of the counterweight plate 1, or correspond to the width of the counterweight plate 1. The counterweight plate 1 is generally made of iron, aluminum alloy, or stainless steel, and its density is greater than that of the connecting bodies 8. Since the counterweight plate 1 is horizontally arranged, the mounting surface is mainly formed by the upper surface of the counterweight plate 1, which primarily serves to fit and install the vehicle body.

[0026] To improve the stable assembly connection between the connecting structure 4 and the connecting body 8, a connecting ring 82 extending downward is integrally formed on the lower surface of the connecting body 8. A pivot 41, which is inserted into the connecting ring 82 with a gap, is provided at the upper end of the connecting structure 4. A limiting opening 42 with a certain circumferential dimension is formed on the outer circumferential surface of the pivot 41. A strip-shaped limiting body 85 is provided protruding on the inner circumferential surface of the connecting ring 82. The limiting body 85 is inserted into the limiting opening 42 with a gap. The mutually cooperating limiting opening 42 and limiting body 85 limit the relative deflection angle between the connecting structure 4 and the connecting body 8. A connecting bolt 9 passing through the connecting body 8 connects the pivot 41 and the connecting body 8. The connecting bolt 9 and the connecting body 8 are in a clearance fit. To improve the smoothness of rotation between the connecting structure 4 and the connecting body 8, a metal sleeve 10 is fitted with a gap at the upper end of the connecting bolt 9. The metal sleeve 10 is embedded in the connecting body 8. When the pivot 41 rotates, only sliding friction occurs between the connecting bolt 9 and the metal sleeve 10.

[0027] A hollow insert post 81 is integrally formed on the lower surface of the connector 8 within the connector ring 82. The insert post 81 is coaxially and intermittently inserted into the pivot 41. The connector bolt 9 is intermittently inserted into the insert post 81 and achieves a threaded connection with the connector structure 4.

[0028] The two connecting bodies 8 are provided with connecting tongue and groove 83 at their opposite side edges. The end of the counterweight plate 1 is embedded in the connecting tongue and groove 83, and the upper surface of the counterweight plate 1 is flush with the upper surface of the connecting body 8. Figure 1 , 2 As shown in Figure 3, a hollow connecting post 84 is provided protruding on the bottom surface of the connecting tongue and groove 83, and a clearance opening is provided on the counterweight plate 1, with the connecting post 84 located at the clearance opening.

[0029] The connecting structure 4 is equipped with a positioning wheel 5, which is vertically positioned. The positioning wheel 5 is located below the load-bearing roller 3, and there is a gap between the positioning wheel 5 and the load-bearing roller 3. A limiting wheel 6 is also provided on the outer side of the connecting structure 4. The limiting wheel 6 is horizontally positioned and is used to contact the side of the track to limit the horizontal movement of the vehicle on the track.
