Description

Technical Field

[0001] The utility model relates to the technical field of printing plate cylinder handling, in particular to a printing plate cylinder transfer vehicle. Background Art

[0002] For the need of printing various decorative patterns on larger format paper, decorative paper manufacturers often use many printing plate cylinders engraved with different patterns. These large and medium-sized steel plate cylinders are very smooth and very heavy. The roller surfaces of the printing plate cylinders weighing from several hundred kilograms to nearly one ton are engraved with delicate patterns. They cannot be collided during handling to avoid damaging the engravings and affecting the printing quality. With different decorative patterns of decorative paper, printing machines often need to replace different plate cylinders. It is the daily operation of these manufacturers to transport the plate cylinders back and forth from the plate cylinder storage warehouse to the printing workshop.

[0003] Currently, two types of transfer vehicles are commonly used for handling. One is a trolley that converts vertically stored plate cylinders into a horizontal position, and the other is a trolley that transfers the plate cylinders obliquely. The two trolleys need to work together, which is rather troublesome. Therefore, a transfer vehicle that combines the two is needed to meet the handling requirements. Summary of the Utility Model

[0004] In view of the above problems, the utility model provides a printing plate cylinder transfer vehicle, which can transfer vertically placed plate cylinders, can be quickly transformed into an inclined state for easy pushing, and can also be transformed into a horizontal state for easy handling by a hydraulic forklift, and is convenient to use.

[0005] To solve the above problems, the technical solution adopted by the utility model is:

[0006] A printing plate cylinder transfer vehicle includes a vehicle frame. A pair of wheels are installed at the bottom of the front end of the vehicle frame. A bottom support plate perpendicular to the vehicle frame is fixedly installed at the top of the front end of the vehicle frame. A support plate parallel to the bottom support plate is fixedly connected to the top of the rear section of the vehicle frame. A pair of support legs corresponding to the position of the support plate are fixedly installed at the bottom of the rear section of the vehicle frame. A pair of cushion rollers are installed between the opposite side walls of the support plate and the bottom support plate. A pair of rotating arms are installed between the support legs and the wheels of the vehicle frame. The ends of the pair of rotating arms are rotatably connected with rollers. A locking component for locking the rotation angle is installed on the rotating arms.

[0007] Preferably, a pair of mounting plates are fixedly connected to the bottom of the front end of the vehicle frame, and the pair of wheels are respectively rotatably connected to the corresponding mounting plates.

[0008] Preferably, the bottom support plate is flat and has a slope at the end.

[0009] Preferably, a handle is fixedly connected to the rear end of the vehicle frame.

[0010] Preferably, a fixing plate is fixedly connected between the vehicle frame and the support legs and the wheels. The end of the swing arm is rotatably connected to the fixing plate, and a limiting plate for restricting the rotation angle of the swing arm is fixedly connected to the bottom of the fixing plate.

[0011] Preferably, a limiting rod is inserted into the side wall of one of the support legs. The end roller of the swing arm can be suspended between a pair of support legs, and the limiting rod is used to restrict the position of the swing arm.

[0012] Preferably, the locking assembly includes a connecting arm rotatably connected to the side wall of the swing arm. A threaded sleeve is threadedly connected to the end of the connecting arm. The inner and outer surfaces of the threaded sleeve are respectively provided with internal and external threads. A threaded section threadedly connected to the internal thread is provided at the end of the connecting arm. An inclined fixing seat is fixedly connected between the support legs and the fixing plate at the bottom of the vehicle frame. A threaded groove adapted to the external thread is provided at the bottom of the inclined fixing seat.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. By installing wheels, a bottom support plate, a support plate, cushion rollers and support legs, the vehicle frame can be transformed from a vertical state to a horizontal state. In the vertical state, when the bottom of the vertical plate roller is slightly tilted, the bottom support plate can be inserted to place the plate roller on the bottom support plate. After being transformed into the horizontal state, the two ends of the plate roller can be supported by two pairs of cushion rollers. The support legs and wheels support the vehicle frame and keep it in a horizontal state. At this time, a hydraulic forklift can be inserted from below the plate roller for handling, which is convenient to use.

[0015] 2. By installing a swing arm, rollers, a limiting rod and a locking assembly, during the process of transforming from a vertical state to a horizontal state, the swing arm and rollers are received between a pair of support legs. Insert the limiting rod to restrict the position of the swing arm. When inclined handling is required, after placing the plate roller on the vehicle frame in the vertical state, release the limit on the swing arm. The swing arm rotates to the restricted position with the limiting plate. Rotate the connecting arm, align the threaded sleeve with the inclined fixing seat, rotate the threaded sleeve to extend the connecting arm, and finally screw it into the threaded groove to complete the locking. At this time, the vehicle frame can be tilted and supported and transported through the rollers and wheels. The transformation is fast and the transportation is stable.

[0025] Further, a pair of mounting plates 9 are fixedly connected to the bottom of the front end of the vehicle frame 1, and a pair of wheels 10 are respectively rotatably connected to the corresponding mounting plates 9 to achieve stable support for the vehicle frame 1.

[0026] Further, the bottom support plate 5 is flatly arranged and has a slope at the end, which is convenient for inserting the bottom of the plate roller and placing it on the bottom support plate 5.

[0027] Furthermore, a handle 2 is fixedly connected to the rear end of the frame 1, facilitating the worker to push it.

[0028] Furthermore, a fixing plate 7 is fixedly connected between the support leg 14 and the wheel 10 of the frame 1. The end of the swing arm 11 is rotatably connected to the fixing plate 7. A limiting plate 8 for restricting the rotation angle of the swing arm 11 is fixedly connected to the bottom of the fixing plate 7. After the swing arm 11 is swung out, the position of the swing arm 11 can be quickly restricted by the limiting plate 8.

[0029] Furthermore, a limiting rod 16 is inserted into the side wall of one of the support legs 14. The end roller 15 of the swing arm 11 can be suspended between a pair of support legs 14. The limiting rod 16 is used to restrict the position of the swing arm 11. During the process of transitioning from the vertical state to the horizontal state, the swing arm 11 and the roller 15 are received between a pair of support legs 14, and the limiting rod 16 is inserted to restrict the position of the swing arm 11. When inclined handling is required, after simply placing the frame 1 in the vertical state on the plate roller, the restriction on the swing arm 11 is released.
