Abstract
Description
Technical Field
[0001] This utility model relates to a vehicle for running on a conveyor line, and more particularly to a rear force-bearing rod on the vehicle for receiving power from the power line when the vehicle changes track. Background Technology
[0002] For multi-station conveyor lines, carriers are needed to transport product components. The conveyor line includes a main rail, with several branch rails running along its outer edge. Each branch rail constitutes a workstation, and each workstation houses a work position where an operator sits and completes the corresponding product process. When the carrier moves on the main rail, it is powered by the main power line; when moving on the branch rails, it is generally powered by the branch power lines. However, during track changes—that is, when the carrier moves from the main rail to a branch rail, or vice versa—the carrier may not easily receive power. Therefore, existing carriers are equipped with a front force bar and a rear force bar. The front force bar receives power from the main power line, enabling the carrier to move on the main rail; the rear force bar receives power from the main power line when the carrier moves from the main rail to a branch rail, and receives power from the branch power lines when the carrier moves from a branch rail to the main rail. By setting front and rear force rods, the vehicle can move normally on the main rail and change tracks between the main rail and the support rail.
[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 that uses a pressure block installed on the inner side of the track at the track-changing position to press down the force-bearing end of the rear force-bearing rod, allowing it to receive power from the main force line or the branch force line. The lower force-bearing rod of the carrier has a protruding extension at its force-bearing end. The pressure block applies sliding pressure to this extension, lowering the force-bearing end of the rear force-bearing rod to receive power from the corresponding force line. However, the sliding pressure of the pressure block on the rear force-bearing rod increases the resistance of the carrier during track-changing. As the rear force-bearing rod gradually lowers, the carrier may stall before receiving power at the force-bearing end of the lower force-bearing rod, thus affecting the normal track-changing process. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a rear force-bearing rod for a conveyor line carrier, which provides low resistance to the carrier's movement when the carrier changes tracks, thus facilitating smooth track changes.
[0006] To solve the aforementioned technical problem, the present invention provides the following technical solution: a rear force-bearing rod for a conveyor line carrier, which is horizontally and movably mounted on a connecting block on the rear side of the carrier, comprising an upper rod and a lower rod. The inner end of the upper rod is movably hinged to a mounting opening on the connecting block, and the inner end of the lower rod is hinged to the middle position of the upper rod. A spring acts on the lower rod. The characteristic feature is that the width of the mounting opening is greater than the width of the upper rod; protruding rods are respectively provided on opposite sides of the lower rod, and bearings are sleeved on the outer ends of the protruding rods.
[0007] The extendable rod is typically integrated with the lower rod, or it can be formed by a rod-like body passing through the lower rod. The extension length of the extendable rod and the position of the pressure block ensure that during track changing, the pressure block directly contacts the bearing, and the bearing rollers allow the extendable rod to pass smoothly through the pressure block. The width of the mounting opening is greater than the width of the upper rod, allowing the rear load-bearing rod to swing left and right during track changing to adapt to the vehicle's positional changes.
[0008] Furthermore, the outer diameter of the bearing corresponds to the outer diameter of the extension rod. This bearing has a relatively small outer diameter, not differing much from the outer diameter of the extension rod, resulting in good stability in the fit between the bearing and the pressure block.
[0009] Furthermore, vertically arranged springs bridge the connecting block and the upper rod. The springs are typically made of metal, such as copper, stainless steel, or sheet metal, and possess a certain degree of elasticity. This allows for easy correction of the position of the rear load-bearing rod, ensuring it quickly returns to its original position in the vehicle's direction of travel after a track change. This prevents the rear load-bearing rod from generating significant resistance and increasing power consumption during vehicle movement. Simultaneously, it effectively ensures the stability of the upper end of the front load-bearing rod on the rear vehicle during vehicle stacking, provided by the rear load-bearing rod on the front vehicle.
[0010] Furthermore, the connecting block has a slit, and the upper rod has a clamping part. The outer end of the spring is fixed in the clamping part, and the inner end of the spring is inserted into the slit. This direct insertion of the inner end of the spring into the slit facilitates the assembly of the spring.
[0011] Furthermore, a support rod is provided at the clamping position on the upper rod, with both ends extending to opposite sides of the upper rod. Guide wheels are rotatably mounted at both ends of the support rod, with their outer circumferential surfaces protruding outwards from the ends of the support rod. The support rod and guide wheels facilitate maintaining the position of the rear load-bearing rod, and the contact between the guide wheels and the rollers on the inner wall of the track effectively reduces the resistance force experienced by the vehicle during movement.
[0012] Furthermore, the support rod is a groove-shaped body, and the guide wheel is located on the lower side of the bottom surface of the support rod; the clamping part includes two clamping plates, and the outer end of the spring is fixed between the two clamping plates, with the clamping plates located inside the support rod. The two clamping plates clamp and fix the outer end of the spring, resulting in good stability of the spring. The clamping plates are set inside the support rod, resulting in good structural compactness.
[0013] Furthermore, the upper rod is hinged to the mounting port by a fixing bolt, and a metal sleeve is fitted around the outer periphery of the fixing bolt, with the metal sleeve embedded in the upper rod. Due to the metal sleeve, when the rear load-bearing rod swings on the connecting block, sliding friction occurs between the metal sleeve and the fixing bolt, resulting in smooth swinging of the rear load-bearing rod and effectively adapting to the positional requirements of the rear load-bearing rod during vehicle track changes.
[0014] Compared with existing technologies, this utility model has the following advantages: By providing an extension rod on the lower rod of the rear force-bearing rod, installation is convenient and material usage is reduced. The extension rod's position on the lower rod allows for sufficient downward pressure from the pressure block, facilitating the lower rod's reception of power from the corresponding power line. Furthermore, the bearing at the outer end of the extension rod effectively reduces the resistance force exerted on the vehicle when the pressure block applies pressure to the lower rod, improving the smoothness of the vehicle's track changes.

[0019] Referring to the accompanying drawings, the rear support rod of this conveyor line carrier is horizontally and movably mounted on the connecting block 2 at the rear of the carrier 1. The structure includes an upper rod 51 and a lower rod 52. The lower rod 52 receives the thrust from the push block on the power line when the carrier 1 changes track. The inner end of the upper rod 51 is movably hinged to the mounting opening 4 on the connecting block 2. The width of the mounting opening 4 is greater than the width of the upper rod 51, allowing the rear support rod 5 to swing left and right within the mounting opening 4 to adapt to the positional requirements of the rear support rod 5 when the carrier 1 changes track. The outer end of the upper rod 51 has an upwardly inclined extension, which is used to allow the rear end of the upper rod 51 in the rear force rod 5 of the front vehicle 1 to abut against the outer end of the front force rod 3 of the rear vehicle 1 when the vehicles 1 are stacked, so that the force-bearing end of the front force rod 3 is raised, thereby disengaging the force-bearing end from the push block on the power line, so that the rear vehicle 1 loses its driving power and adapts to the stopping of the front vehicle 1, and the rear vehicle 1 will also stop in sequence at the rear.
[0020] In the rear force-bearing rod 5, the inner end of the lower rod 52 is hinged to the middle position of the upper rod 51. A torsion spring is provided at the inner end of the lower rod 52, and the outer end of the torsion spring acts on the lower rod 52, so that under normal circumstances, the force-bearing end of the lower rod 52 is in an upward state, and the force-bearing end of the lower rod 52 does not receive power from the power line. A pressure block is provided at the track-changing position on the conveyor line. The lower end face of the pressure block is located at a relatively low position. During the track-changing process of the carrier 1, the lower rod 52 will be subjected to the downward pressure of the pressure block, and the force-bearing end of the lower rod 52 will move to the position of the push block on the power line to receive the push from the power line, thus realizing the smooth track-changing of the carrier 1. After the track-changing of the carrier 1 is completed, under the action of the torsion spring, the force-bearing end of the upper rod 51 returns to its original upward position and disengages from the position of the push block. The subsequent travel power of the carrier 1 is provided by the push block on the corresponding power line.
[0021] As shown in the figure, protruding rods 53 are provided on opposite sides of the lower rod 52. The protruding rods 53 are in a horizontal position and are integrally formed with the lower rod 52. A bearing 8 is sleeved on the outer end of the protruding rod 53, and the outer diameter of the bearing 8 is not much different from the outer diameter of the protruding rod 53. When the carrier 1 changes track, the corresponding pressure block will lower the force-bearing end of the lower rod 52 by resisting the bearing 8.
[0022] Ideally, when the vehicle 1 is traveling normally, the rear force-bearing rod 5 on the vehicle 1 is positioned in the direction of travel of the vehicle 1 to reduce the large resistance force exerted by the track on the vehicle 1. A spring 6 with a certain elastic force is provided between the connecting block 2 and the upper rod 51. The spring 6 is vertically arranged and bridges the connecting block 2 and the upper rod 51. During track change, the rear force-bearing rod 5 overcomes the elastic force of the spring 6 and swings at a certain angle. After the track change is completed, the rear force-bearing rod 5 returns to the ideal position under the action of the elastic force of the spring 6. A slit is provided on the upper side of the mounting port 4 on the connecting block 2, and a clamping part is provided on the upper rod 51. The outer end of the spring 6 is fixed in the clamping part, and the inner end of the spring 6 is inserted into the slit. The spring 6 and the slit are in a transition fit.
[0023] A support rod 54 is provided on the upper rod 51 at the clamping position, and the support rod 54 is integrated with the upper rod 51. The support rod 54 is parallel to the extending rod 53, and its two ends extend to opposite sides of the upper rod 51. Guide wheels 7 are rotatably provided at both ends of the support rod 54, and the outer circumferential surfaces of the two guide wheels 7 protrude to the outer sides of the two ends of the support rod 54 respectively. The outer circumferential surfaces of the guide wheels 7 are used to contact the inner surface of the track, thereby correcting the position of the rear force-bearing rod 5 in real time. The support rod 54 is a groove-shaped body with the opening facing upward, and the guide wheels 7 are located on the lower side of the bottom surface of the support rod 54. The clamping part includes two clamping plates 55, and the outer end of the spring 6 is fixed between the two clamping plates 55. The clamping plates 55 are located inside the support rod 54. The two clamping plates 55 clamp and fix the spring 6 by passing a connecting bolt 10 through the clamping plates 55 and the spring 6.
[0024] The upper rod 51 is hinged to the mounting port 4 by a fixing bolt 9, which is threaded onto the connecting block 2. A metal sleeve is fitted around the outer circumference of the fixing bolt 9, and the metal sleeve is embedded in the upper rod 51 and fixedly connected to the connecting block 2.
