Description

Technical Field

[0001] This utility model relates to a vehicle for running on a conveyor line, and more particularly to a traveling part of a vehicle frame. 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 conveyor line is usually required. The product components are loaded into the conveyor line and transported 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 conveyors.

[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, which includes a carrier frame and a material tray. The material tray rests on the carrier frame. A traveling part is provided on the lower side of the carrier frame. The traveling part includes two connecting blocks. Load-bearing rollers and limiting rollers are provided on opposite sides of each connecting block in the left-right direction. To enable the carrier to receive power from the power line, a front force-bearing rod is provided on the front connecting block, and a rear force-bearing rod is provided on the rear connecting block. To connect the front and rear force-bearing rods, extension arms extending outwards are provided on both connecting blocks, and the front and rear force-bearing rods are movably connected to the two extension arms respectively. Using extension arms to connect the front and rear force-bearing rods results in a relatively complex structure, requiring a relatively large number of parts. The connection strength between the force-bearing rods and the extension arms is limited by the structural strength of the extension arms, making the extension arms prone to damage due to wear of the force-bearing rods. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a conveyor frame traveling part that can adapt well to the movable connection of the force-bearing rod, and the movement stability of the force-bearing rod on the connecting block is good.

[0006] To solve the aforementioned technical problem, the present invention provides the following technical solution: a conveyor frame traveling part, comprising a block-shaped connecting block, on which load-bearing rollers and limiting rollers are rotatably arranged on opposite sides in the left-right direction. The load-bearing rollers are vertically arranged, and the limiting rollers are horizontally arranged. A force-bearing rod is movably arranged on the connecting block, with the force-bearing end of the force-bearing rod extending downward toward the connecting block. The key feature is that an installation groove is provided on the lower corner of the front and rear ends of the connecting block. The installation groove is formed by the corresponding part of the connecting block being recessed into the interior of the connecting block, and the force-bearing rod is pivotally connected in the installation groove.

[0007] The traveling unit is connected to the carrier frame, and the material tray rests on the carrier frame. In practical applications, load-bearing rollers support the track, and the track supports the carrier and the loaded workpiece through the load-bearing rollers. The load-bearing rollers roll forward on the track to achieve long-distance transport of the workpiece. Limiting rollers abut against the side of the track to limit the carrier's movement on the track, ensuring the carrier's position and stable forward movement.

[0008] Furthermore, the mounting grooves are provided at corresponding locations at both ends of the connecting block. Both ends of the connecting block can accommodate the installation of load-bearing rods, which makes the connecting block structurally simple and well adaptable to situations where the vehicle frame requires multiple connections.

[0009] Furthermore, the mounting slot on the front side of the connecting block is the front mounting slot, and the mounting slot on the rear side is the rear mounting slot. The force-bearing rod installed in the front mounting slot is the front force-bearing rod, and its middle position is pivotally connected to the side wall of the front mounting slot. The force-bearing rod installed in the rear mounting slot is the rear force-bearing rod, and its rear force-bearing rod is pivotally connected to the top of the rear mounting slot. The front force-bearing rod can swing up and down to a certain extent, and the rear force-bearing rod can swing left and right to a certain extent, which can well adapt to the forward movement and track-changing movement of the vehicle on the power line.

[0010] Furthermore, an elastic element is provided between the rear force-bearing rod and the connecting block. The elastic force of the elastic element causes the rear force-bearing rod to be arranged along the forward direction of the connecting block. The elastic element has the ability to deform under force. The presence of the elastic element allows the rear force-bearing rod to return to the forward state of the vehicle after the track change, so as to avoid wear and increased resistance caused by the rear force-bearing rod not being parallel to the track.

[0011] Furthermore, the elastic element is a spring, which is vertically arranged, with its two ends connected to the connecting block and the rear force-bearing rod, respectively. This spring has a simple structure, small size, is easy to install, and facilitates the application of force to the rear force-bearing rod.

[0012] Furthermore, a clamping portion is formed on the rear force-bearing rod, and a slot is provided at a corresponding position on the connecting block. One end of the spring is inserted into the slot, and the other end of the spring is clamped by the clamping portion. This facilitates the installation of the spring, and the spring can provide good positional restoring force for the rear force-bearing rod.

[0013] Furthermore, a connecting post is provided on each of the opposite sides of the connecting block in the left-right direction. The connecting post extends to the outside of the connecting block, and the load-bearing roller is rotatably fitted onto the connecting post. The connecting post facilitates the provision of a position for the installation of the load-bearing roller on the connecting block.

[0014] Furthermore, hollow connecting seats are respectively provided on opposite sides in the left-right direction of the connecting block, and the limiting roller is rotatably mounted on the connecting seat, with the limiting roller protruding to the outside of the connecting seat. The connecting seat facilitates the installation of the limiting roller, and the limiting roller has good positional stability within the connecting seat.

[0015] Furthermore, positioning rollers are provided on opposite sides of the connecting block in the left and right directions. The positioning rollers are vertically arranged and located below the load-bearing rollers, with a gap between them. Inward-facing baffles can be installed on the track. During assembly, the baffles are positioned between the positioning rollers and the load-bearing rollers. Under the constraint of the baffles, the connecting block is less likely to detach from the track during operation, ensuring the stability of the vehicle's movement on the track.

[0016] Furthermore, the connecting block has a connecting structure for movably connecting with the carrier frame. A vertically mounted spring is fixed to the connecting block, extending towards the connecting structure, and is used to connect with the carrier frame. Through the arrangement of the spring, the relative position between the connecting block and the carrier frame can be reset, ensuring that each roller adapts to the position of the carrier frame and that the engagement position between each roller and the track is correct.

[0017] Compared with the prior art, the present invention has the following advantages: the connecting block is a block-shaped body, and the mounting groove is directly formed on the connecting block. The mounting groove is formed by the inward indentation of the connecting block, and the strength of the sidewall of the mounting groove depends on the material of the connecting block itself. High sidewall strength of the mounting groove results in good stability of the load-bearing rod within the mounting groove. Since the top of the mounting groove is directly the connecting block body, even if the load-bearing rod collides with the top of the mounting groove during operation, it will not cause significant wear and damage to the connecting block, resulting in a long service life for both the connecting block and the load-bearing rod.

[0023] Referring to the accompanying drawings, the traveling part of the conveyor frame is mounted on the carrier frame 1 and is used to contact the track. The track supports the traveling part and provides a path for its movement.

[0024] The structure of this walking mechanism includes a block-shaped connecting block 2. Figure 1 , 2 As shown, under normal circumstances, one carrier frame 1 corresponds to two connecting blocks 2, with the two connecting blocks 2 separated and positioned on the lower side of the carrier frame 1. Load-bearing rollers 3 and limiting rollers 6 are rotatably mounted on opposite sides of each connecting block 2 in the left-right direction. The load-bearing rollers 3 are vertically mounted, while the limiting rollers 6 are horizontally mounted. The load-bearing rollers 3 are used to rest on the support surface of the track, and can be directly pivotally connected to the corresponding side of the connecting block 2. Figure 3 , 4 In the middle, a connecting post 21 is provided on each of the opposite sides in the left and right directions of the connecting block 2. The connecting post 21 and the connecting block 2 are integrally formed of the same material. The connecting post 21 is formed protrudingly at the top position of the connecting block 2. The outer end of the connecting post 21 extends to the outside of the connecting block 2, and the load-bearing roller 3 is rotatably sleeved on the outer end of the connecting post 21.

[0025] A force-bearing rod is movably mounted on the connecting block 2. The force-bearing end of the rod extends downwards from the connecting block 2. This force-bearing end is used to abut against a pusher block on the power line of the conveyor. Under the push of the pusher block, the force-bearing rod is forced to move the load-bearing roller 3 on the track. To install the force-bearing rod, mounting grooves are provided on the lower corners of the front and rear ends of the connecting block 2. There can be one mounting groove, or there can be one mounting groove at the lower corners of both the front and rear ends of the connecting block 2. The mounting grooves are formed by the corresponding parts of the connecting block 2 recessed into the interior of the connecting block 2. The mounting grooves can be formed after the connecting block 2 is formed, but usually, they are formed during the molding of the connecting block 2. The force-bearing rod is pivotally connected to the mounting groove via a pivot.

[0026] Based on the vehicle's forward direction on the track, the mounting slot on the front side of the connecting block 2 is the front mounting slot 25, and the mounting slot on the rear side is the rear mounting slot 22. The force-bearing rod installed in the front mounting slot 25 is the front force-bearing rod 4. The middle part of the front force-bearing rod 4 is pivotally connected to the side wall of the front mounting slot 25, and both its upper and lower ends extend to the outside of the mounting slot. The force-bearing rod installed in the rear mounting slot 22 is the rear force-bearing rod 8. The rear force-bearing rod 8 is pivotally connected to the top of the rear mounting slot 22, and its rear end extends to the rear side of the connecting block 2. The rear end of the rear force-bearing rod 8 can swing left and right around its pivot point at its front end. When the vehicle travels on the main track, or after the vehicle merges with the branch track, the vehicle's forward propulsion is provided by the pusher block pushing against the force-bearing end of the front force-bearing rod 4. When the vehicle changes track, the force-bearing end of the rear force-bearing rod 8 receives the thrust of the push block to provide power for the vehicle to change track. A pressure block is provided at the track-changing position. The pressure block presses the lower rod in the rear force-bearing rod 8 downward, so that the force-bearing end on the lower rod is in a position that can accept the thrust of the push block.

[0027] An elastic element is provided between the rear force-bearing rod 8 and the connecting block 2. The elastic force of the elastic element causes the rear force-bearing rod 8 to be arranged along the forward direction of the connecting block 2. As shown in the figure, the elastic element is a sheet-like spring 7. The thickness of the spring 7 is generally no more than one millimeter. The spring 7 is vertically arranged, and its two ends are connected to the connecting block 2 and the rear force-bearing rod 8, respectively. When the vehicle changes tracks on the power line, the rear force-bearing rod 8 can overcome the elastic force of the spring 7 and swing to a certain extent. However, after the track change is completed, the elastic force of the spring 7 causes the rear force-bearing rod 8 to be rearranged in the forward direction of the vehicle.

[0028] A clamping part 26 is formed on the rear force-bearing rod 8. The clamping part 26 is composed of two clamping plates integrally formed on the connecting block 2. The other end of the spring 7 is inserted into the gap between the two clamping plates. The clamping plates can clamp the spring 7 by passing a fastening bolt through the clamping plates and the spring 7. A slot 23 is provided at the corresponding position of the connecting block 2. The width of the slot 23 is adapted to the thickness of the spring 7. One end of the spring 7 is naturally inserted into the slot 23. No additional fastening structure is required between the spring 7 and the slot 23.

[0029] Hollow connecting seats 24 protrude from opposite sides of the connecting block 2 in the left and right directions. The connecting seats 24 are hollow quadrangular prisms with outward openings. A limiting roller 6 is rotatably mounted on the bottom surface of the connecting seat 24. The limiting roller 6 is stably pivotally connected to the connecting seat 24 by a connecting bolt, which passes through the connecting seat 24. A nut is provided inside the connecting seat 24, and the nut is threadedly connected to the connecting bolt. The outer circumferential surface of the limiting roller 6 protrudes to the outside of the connecting seat 24. The limiting roller 6 is inserted into a grooved track, and its outer circumferential surface contacts the inner wall of the track, thus limiting the movement of the connecting block 2 on the track.

[0030] Positioning rollers 5 are provided on opposite sides of the connecting block 2 in the left and right directions. The positioning rollers 5 are vertically arranged and located below the load-bearing rollers 3, with a gap between them. A baffle can be integrally formed at the inner edge of the upper opening of the aforementioned track. When the traveling part is engaged with the track, the positioning rollers 5 are located below the baffle, and the traveling part will not detach from the track under normal circumstances.

[0031] The connecting block 2 has a connecting structure for movably connecting with the carrier frame 1. The connecting structure is a columnar connecting body 27 integrally formed on the top of the connecting block 2. A sleeve-shaped connecting sleeve is provided on the carrier frame 1, and the connecting sleeve is movably fitted onto the connecting body 27. A clamping part 26 is integrally formed on the connecting block 2. A vertically arranged spring 7 is fixed on the clamping part 26. The spring 7 extends toward the connecting body 27, and the outer end of the spring 7 is inserted and connected to the connecting sleeve.
