Background Technology

[0002] In production lines such as painting and assembly, overhead conveyor lines are a highly efficient spatial material handling system. Workpieces are suspended on tracks by hangers and driven by a drive unit. However, transferring materials between different workstations requires multiple track changes, which occupies a large space and has low efficiency, and needs to be addressed. Utility Model Content

[0003] The purpose of this invention is to provide a manually controlled translation vehicle device for overhead conveyor lines that is simple in structure, flexible in operation, and safe and reliable, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A manually controlled translation trolley device for a suspended conveyor line includes a heavy-duty multi-wheel trolley, a track transfer frame, a handrail frame, a control unit, a male connector, and a female connector.

[0006] Further describing this utility model, the heavy-duty multi-wheel trolley is suspended from the external main trolley track by a bearing assembly at its top, allowing it to slide freely along the track; its bottom is equipped with a track transfer frame via a track hanger; the track transfer frame includes a transfer track, a support plate, a crossbeam, and a handrail connecting plate; the transfer track is used to carry the workpiece to be transferred and its lifting equipment; the support plate is located above the transfer track and is connected by the crossbeam to form a stable rectangular frame structure; the handrail connecting plate is fixed to the top of the support plate; the handrail frame includes a connecting rod, a corner fixing plate, a push-pull frame, and a flexible shaft mounting plate; the top of the handrail frame is fixed to the handrail connecting plate of the track transfer frame via the connecting rod, allowing the operator to move the entire device by pushing and pulling the handrail frame; the control unit is installed on the flexible shaft mounting plate of the handrail frame and includes a handle, a flexible shaft, and a U-shaped fastener; the male connector is fixed to both ends of the transfer track of the track transfer frame; the female connector is fixed to the end of the external docking track to which it needs to dock.

[0007] Further describing this utility model, its working principle is as follows: The operator manually pushes or pulls the handrail frame to move the entire device along the main trolley track to the workstation requiring docking; by operating the handle of the control unit, the flexible shaft is pulled to control the lifting and lowering of the limiting plate in the male docking head; when the male docking head approaches the female docking head, the handle is released, and the limiting plate falls under the action of the spring, completing the mechanical interlock with the female docking head, thereby realizing the precise connection between the transfer track and the external docking track; at this time, the workpiece lifting device can safely move from the transfer track to the external docking track, or move in the opposite direction; when separating, the operating handle pulls up the limiting plate, and the translation trolley device can be manually moved away.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1 to 7 As shown, the present invention provides a manually controlled translation vehicle device for a suspended conveyor line, which mainly consists of a heavy-duty multi-wheel trolley 1, a track transfer frame 2, a handrail frame 3, a control unit 4, a male docking head 5, and a female docking head 6.

[0031] The heavy-duty multi-wheeled trolley 1 is the suspension and traveling component of the device. For example... Figure 2 As shown, it includes a bearing assembly 11, a trolley main plate 12, guide wheels 13, a track hanger 14, a top set screw 15, and a side set screw 16. The bearing assembly 11 straddles the external travel rail 7. The trolley main plate 12 is suspended below the bearing assembly 11 by pins. The guide wheels 13 are horizontally installed at the front and rear ends of the top of the trolley main plate 12, contacting the sides of the track to prevent the vehicle from deviating. The track hanger 14 is vertically fixed to the bottom of the trolley main plate 12 and is used to hoist the track transfer frame 2. By tightening the top set screw 15 and the side set screw 16, the track transfer frame 2 can be firmly locked onto the track hanger 14, ensuring a stable connection and facilitating installation and adjustment.

[0032] The track transfer frame 2 consists of transfer tracks 21, support plates 22, crossbeams 23, and handrail connecting plates 24. The support plate 22 is fixed above the transfer tracks 21. The two sets of transfer tracks are connected by the crossbeams 23 to form a rigid rectangular frame, ensuring no deformation under load. The support plate 22 has pre-drilled holes for the flexible shaft 42 of the control unit 4 to pass through. The handrail connecting plate 24 is welded to the top of the support plate 22.

[0033] The handrail frame 3 consists of a connecting rod 31, corner fixing plates 32, a push-pull frame 33, and a flexible shaft mounting plate 34. The connecting rod 31 and the push-pull frame 33 are connected to the corner fixing plates 32, and the connecting rod 31 is fixed to the handrail connecting plate 24 of the track transfer frame 2. The flexible shaft mounting plate 34 is fixed on the push-pull frame 33 and is used to install the control unit 4. The operator can drive the entire device to move by pushing and pulling the push-pull frame 33.

[0034] like Figure 5 As shown, the control unit 4 includes a handle 41, a flexible shaft 42, and a U-shaped fastener 43. The handle 41 is fixed to the flexible shaft mounting plate 34 for easy operation. One end of the flexible shaft 42 is connected to the handle 41, and the other end passes through a round hole on the support plate 22 and is connected to the rotating tab 58 of the male connector 5 via the U-shaped fastener 43. This design ensures that the flexible shaft 42 will not loosen or shift during transmission.

[0035] like Figure 6 As shown, the male connector 5 includes a male connector track fastener 51, side wing plates 52, fastening screws 53, a first support plate 54, a limiting plate 55, a second support plate 56, a shaft pin 57, a rotating tab 58, and a spiral spring 59. The male connector track fastener 51 is fixed to the end of the transfer track 21 by the fastening screws 53. The side wing plates 52 are symmetrically fixed on both sides of the male connector track fastener 51. The first support plate 54 and the second support plate 56 are fixed on the male connector track fastener 51 to support the shaft pin 57. The limiting plate 55 is fixedly installed on the shaft pin 57; the rotating tab 58 is fixed to the end of the shaft pin 57 and forms a certain angle with the limiting plate 55. The spiral spring 59 is fixed on the second support plate, providing the torque to reset the limiting plate 55. In its natural state, the spiral spring 59 keeps the limiting plate 55 in a horizontal position. When the operating handle 41 pulls the flexible shaft 42, the flexible shaft 42 pulls the rotating tab 58 through the U-shaped fastener 43, causing the shaft pin 57 to rotate, thereby pulling up the limit plate 55.

[0036] like Figure 7As shown, the female connector 6 includes a female connector track fastener 61, guide slope guard plates 62, safety bolt mounting base 63, safety bolt 64, pin 65, and fastening screw 66. The female connector track fastener 61 is fixed to the end of the external docking track 8 by the fastening screw 66. Two guide slope guard plates 62 are symmetrically fixed to the top of the docking end, forming a funnel-shaped guide surface. The safety bolt 64 is placed vertically in the safety bolt mounting base 63 by its own weight, with its bottom extending to the outer edge of the track of the female connector track fastener 61, which can intercept the pulley from the external docking track 8. The pin 65 is used to achieve a rigid connection between the female connector 6 and the external docking track 8 during installation, preventing loosening.

[0037] Work process:

[0038] Preparation and movement: The operator stands in front of the handrail 3 and manually pushes the device along the external trolley track 7 to the target docking station.

[0039] Pre-docking operation: When approaching the female docking head 6, the operator pulls the handle 41 and pulls up the limiting plate 55 of the male docking head 5 through the flexible shaft 42.

[0040] Docking and Locking: Continue pushing the device to slowly insert the male connector 5 into the female connector 6. The male connector track fastener 51 aligns with the female connector track fastener 61. At this point, release the handle 41. Under the action of the spiral spring 59, the limiting plate 55 falls, its bottom precisely locking into the gap between the two guide slope guard plates 62, achieving mechanical interlocking. Simultaneously, during the docking process, the side wing plate 52 of the male connector 5 will push the bottom of the safety bolt 64 of the female connector 6 upwards, thereby clearing the passage.

[0041] Material transfer: At this time, the transfer track 21 is fully connected with the external docking track 8, and the workpiece lifting device can safely move from one track to another.

[0042] Separation: After the transfer is completed, the operator pulls the limit plate 55 by operating handle 41, which allows the transfer car to be manually removed from the docking station. The safety bolt 64 falls back under its own weight, resuming its interception and protection function.

[0043] The number of transfer tracks described in this utility model includes, but is not limited to, the embodiments shown in the accompanying drawings, and can also be expanded to a three-track, four-track, or other multi-track system. The above description is not intended to limit the technical scope of this utility model. Any modifications, equivalent changes, or alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
