Description

Technical Field

[0001] This utility model relates to the field of railway sleeper production technology, and in particular to an automatic railway sleeper conveying device. Background Technology

[0002] Railway sleepers serve to support the rails and maintain their positional stability; therefore, track spikes need to be installed in the spike holes of the sleepers for anchoring. Currently, concrete sleeper anchoring is usually done manually, requiring multiple flipping and stacking of the sleepers. This method is inefficient and labor-intensive. Therefore, how to upgrade the scattered manual anchoring work into a streamlined, automated process is a problem that every concrete sleeper manufacturer needs to solve. Utility Model Content

[0003] This utility model addresses the defects and deficiencies in the existing technology by providing an automatic sleeper conveying device. This device automatically inserts the spiral rail spikes installed on the fixing mechanism into the rail spike holes of the sleeper through a sleeper feeding mechanism, thereby completing the installation of the rail spikes and providing a foundation for the automation of sleeper rail spike anchoring.

[0004] To achieve the above objectives, this utility model provides an automatic sleeper conveying device, including a frame and a sleeper delivery mechanism. The sleeper delivery mechanism is movably mounted on the frame. A fixing mechanism for installing a spiral rail spike is provided at one end of the frame in the sleeper delivery direction, so that the sleeper delivery mechanism delivers the sleeper above the fixing mechanism. The spiral rail spike is movably connected to the fixing mechanism. The sleeper delivery mechanism has a liftable support frame, so that the sleeper delivered by the sleeper delivery mechanism above the fixing mechanism falls, allowing the spiral rail spike installed on the fixing mechanism to be inserted into the rail spike hole pre-drilled on the sleeper.

[0005] Furthermore, the sleeper feeding mechanism includes guide rails arranged on both sides of the frame and along the length of the frame, support frames for supporting sleepers, and telescopic rods. The upper end of the telescopic rod is connected to the support, and its lower end is slidably or rollingly connected to the guide rails through a base. Two support frames are symmetrically arranged on both sides of the frame and connected by connecting rods.

[0006] Furthermore, the support frame includes a horizontally arranged tray and a vertically arranged upright plate. The upright plate is fixed to one end of the tray to form an L-shape, and the two ends of the connecting rod are respectively connected to the top of the two upright plates.

[0007] Furthermore, a wheel seat is fixedly connected to the bottom surface of the base, and a roller adapted to the guide rail is installed on the wheel seat. The roller and the guide rail form a rolling pair.

[0008] Furthermore, the fixing mechanism includes a fixing frame and a fixing plate. The fixing plate is fixedly installed on the top of the fixing frame, and two fixing holes for installing spiral rail spikes are opened on its top, which are the same as the holes on the sleeper. The distance between the two fixing holes is equal to the distance between the holes of the rail spikes on the sleeper. A through hole coaxial with the fixing hole is opened on the fixing frame corresponding to the mounting hole. The bottom end of the spiral rail spike is inserted into the fixing hole and passes through the through hole.

[0009] Furthermore, the fixing frame includes a column and a connecting plate fixed to the top surface of the column. The fixing plate is fixedly connected to the connecting plate. A groove coaxially arranged with the fixing hole is opened on the top surface of the fixing plate, and the flange of the spiral rail spike is placed in the groove.

[0010] Furthermore, a fixing block is fixedly installed on the bottom surface of the connecting plate at the location corresponding to the through hole, and a through hole for the spiral rail spike is opened on the fixing block, which is coaxial with the through hole.

[0011] Compared with the prior art, the present invention has the following technical effects:

[0012] This utility model uses a sleeper feeding mechanism to lift the sleepers from the previous process conveyed by the conveyor and transport them to the top of the fixing mechanism. After the sleepers are transported to the top of the fixing mechanism, they fall down, causing the spiral spikes installed on the fixing mechanism to automatically insert into the spike holes of the sleepers, completing the automatic installation of the spikes and enabling the next process to proceed. This improves work efficiency and provides a foundation for the automation of sleeper spike anchoring. Attached Figure Description

[0021] Example: Figure 1 and 2 As shown, the automatic sleeper conveying device provided in this embodiment is used to lift and transport the sleepers delivered from the previous station by the chain conveyor 3 to the top of the fixing mechanism 4, and then lower them so that the spiral rail spikes 6 are installed in the rail spike holes pre-drilled in the concrete sleepers 5, automatically completing the operation of installing the spiral rail spikes 5 into the rail spike holes, saving manpower, time and labor. The automatic sleeper conveying device includes a frame 1 and a sleeper delivery mechanism 2. The sleeper delivery mechanism 2 is movably mounted on the frame 1. A fixing mechanism 4 for installing the spiral rail spikes 6 is provided at one end of the frame 1. The spiral rail spikes 6 are movably connected to the fixing mechanism 4. The fixing mechanism 4 is located at one end of the frame 1 and arranged at one end of the sleeper delivery mechanism 2 in the sleeper delivery direction, so that the sleeper delivery mechanism 2 delivers the sleepers 5 to the top of the fixing mechanism 4. The sleeper delivery mechanism 2 has a liftable support frame 25 so that the sleepers 5 on the sleeper delivery mechanism 2 fall after being delivered to the top of the fixing mechanism 4, so that the spiral rail spikes 6 installed on the fixing mechanism 4 are inserted into the rail spike holes pre-drilled in the sleepers 5. In this embodiment, the support frame 25 includes a horizontally arranged support plate 251 and a vertically arranged upright plate 252. The upright plate 252 is fixed to one end of the support plate 251 to form an L-shape, and the two ends of the connecting rod 26 are respectively connected to the top of the two upright plates 252.

[0022] The sleeper feeding mechanism 2 includes guide rails 21 arranged on both sides of the frame 1 and along the length of the frame 1, support frames 25 for supporting sleepers 5, and telescopic rods 24. The upper end of the telescopic rods 24 is connected to the support frames 25, and its lower end is connected to the guide rails 21 through the base 22. The two support frames 25 are symmetrically arranged on both sides of the frame 1 and connected by connecting rods 26.

[0023] In this embodiment, the base 22 is welded together from a top plate and a bottom plate arranged in parallel, and a vertically arranged support plate arranged between the top plate and the bottom plate. A wheel seat is fixedly connected to the bottom surface of the bottom plate, and a roller adapted to the guide rail 21 is installed on the wheel seat. The roller and the guide rail 21 form a rolling pair. In other embodiments of this utility model, in the two bases 22, a drive motor 23 is installed on one base 22 to drive the roller, and the other base 22 is driven by a connecting rod 26. The drive motor 23 is a stepper motor. The telescopic rod 24 is a cylinder or a hydraulic cylinder. A solenoid valve is provided on the air pipe connected to the cylinder. When a hydraulic cylinder is used, a solenoid valve is provided on the hydraulic pipe connected to the hydraulic cylinder. Of course, an electric actuator can also be used as one embodiment of this utility model. During operation, the spiral rail spike 6 is vertically installed on the fixed mechanism 4. Driven by the telescopic rod 24, the sleeper 5, transported from the previous station by the chain conveyor 3, is lifted by the support frame 25. The drive motor 23 is started, causing the rollers to move along the guide rail 21 towards the spiral rail spike 6.

The distance between the two fixing holes is equal to the distance between the holes of the rail spikes on the sleeper. A through hole is opened on the fixing frame 41 at the location corresponding to the fixing hole. The through hole is coaxial with the fixing hole. The bottom end of the spiral rail spike 6 is inserted into the fixing hole and passes through the through hole.

[0025] See Figure 2 and Figure 3 The fixing frame 41 includes a column 411 and a connecting plate 412 fixed on the top surface of the column 411. The fixing plate 42 is fixedly connected to the connecting plate 412. A groove 44 coaxially arranged with the fixing hole is provided on the top surface of the fixing plate 42. The flange of the spiral track spike 6 is placed in the groove 44. The cross-section of the groove 44 is a trapezoid with a larger top and a smaller bottom.
