Description

Technical Field

[0001] This utility model relates to the field of rail conveying, specifically to a transposition platform with a spare rail. Background Technology

[0002] In industrial production, rail conveying involves pre-laying tracks and allowing transport trolleys to move along fixed tracks to carry materials, semi-finished products, or finished products along a predetermined route. It features stable operating speed, high positioning accuracy, and high single-section load capacity, making it particularly suitable for heavy-duty, high-frequency, and point-to-point transport scenarios.

[0003] Existing linear transport tracks often use a unidirectional setup to save costs, allowing transport trolleys to move back and forth to move materials to the unloading point. However, when there are multiple production lines, i.e. multiple unloading points, the unloading of materials by the transport trolleys on the transport line can easily cause other trolleys to block the line, resulting in wasted time and reduced production efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a transposition table with a spare track, so as to solve the problem that the existing unidirectional track with multiple unloading points is prone to causing the transport track to be blocked, resulting in wasted time and reduced production efficiency.

[0005] To achieve the above objectives, this utility model provides a switching platform with a spare track, applied to a circular shaft track conveyor line. The circular shaft track conveyor line uses two circular shafts as tracks, and drives the transport trolley to move by rotating the circular shafts. It includes a switching platform, which is equipped with a main track, a spare track, and a discharge hopper. The main track is connected to the circular shaft track conveyor line, and the spare track can be slidably switched with the main track, connecting to the circular shaft track conveyor line after switching. The discharge hopper is located on the side of the circular shaft track conveyor line, and when the main track is switched to the spare track, the main track is located above the discharge hopper.

[0006] The principle and beneficial effects of the technical solution are as follows: the circular shaft track conveyor line is used to enable the transport trolley to make linear reciprocating motion, thereby transporting materials. The switching platform is used to install the main track and the backup track. The main track and the backup track are switchable, and both can be connected to the circular shaft track conveyor line after switching, allowing the transport trolley to pass smoothly. Under normal circumstances, the main track and the circular shaft track conveyor line are connected. When the first trolley moves onto the main track, the main track switches to the backup track. After switching, the main track is located above the unloading hopper, allowing the transport trolley to unload materials autonomously. At this time, the backup track is connected to the circular shaft track conveyor line, which facilitates the passage of subsequent transport trolleys, avoiding blockages, wasting time, and reducing efficiency.

[0007] In a preferred embodiment of this utility model, a slide rail is fixed on the transposition platform, and a slidable transposition plate is provided on the slide rail. The transposition plate is used to fix the main track and the spare track. A driving component is provided in the transposition platform, and the driving component is used to drive the transposition plate to slide and adjust the position of the main track and the spare track. The transposition plate is provided with a discharge hole below the main track.

[0008] Beneficial effects: The switching plate is used to install the main track and the spare track. Driven by the driving component, it moves on the slide rail to achieve the effect of switching the main track and the spare track. The unloading hole is used to allow the transport trolley to unload materials.

[0009] In a preferred embodiment of this utility model, the driving component includes an electric push rod fixed below the transposition platform, a connecting block fixed on the output shaft of the electric push rod, a sliding groove provided on the transposition platform, the connecting block passing through the sliding groove and being fixedly connected to the transposition plate, and the electric push rod and the sliding groove being arranged parallel to the slide rail.

[0010] Beneficial effects: The groove is used to place the connecting block, the electric push rod is used to push out the connecting block, and the switching plate is pulled along the slide rail by the connecting block.

[0011] In a preferred embodiment of this utility model, both the main track and the spare track include multiple mounting seats fixed on the transposition plate. The multiple mounting seats are arranged in two rows, and each of the two rows of mounting seats is provided with a rotatable circular shaft track segment. A bearing is provided between the circular shaft track segment and the mounting seat.

[0012] Beneficial effects: The mounting base is used to install the circular shaft track section, the bearing is used to allow the circular shaft track section to rotate relative to the mounting base, and the circular shaft track section can be connected to the circular shaft track conveyor line as a whole, allowing the transport trolley to pass directly.

[0013] In a preferred embodiment of this utility model, both the main track and the spare track further include a drive motor. A drive sprocket is fixed on the output shaft of the drive motor, and a driven sprocket is fixed on the end face of one of the circular track segments. The drive sprocket and the driven sprocket are connected by a chain, and the outer diameter of the driven sprocket is smaller than that of the circular track segment.

[0014] Beneficial effects: The drive motor is used to drive the active sprocket to rotate, which in turn drives the driven sprocket to rotate via the chain, thereby driving the circular shaft track section to rotate, connecting and driving the transport trolley so that it can smoothly pass through the main track or the backup track.

[0015] In a preferred embodiment of this utility model, a limiting plate is fixed on the side of the transposition plate near the main track, and a first damper is provided on the limiting plate.

[0016] Beneficial effects: The limiting plate is used to stop the transport trolley, and the first damper is used to buffer the impact force of the transport trolley's movement, so that it stops smoothly.

[0017] In a preferred embodiment of the present invention, the two sides of the transposition platform are fixed with limit seats, and the limit seats are provided with a second damper.

[0018] Beneficial effect: The limiting seat is used to limit the maximum movement position of the shift plate and to bring it to a smooth stop through the second damper. Attached Figure Description
