Description

Technical Field

[0001] This utility model relates to the field of printing equipment, and in particular to a mobile transport vehicle for transporting printing rollers. Background Technology

[0002] Printing rollers are essential components of printing equipment, and their quality affects the overall printing quality. Therefore, protecting the quality of printing rollers from damage during the printing process is a prerequisite for ensuring the normal operation of printing.

[0003] The existing printing rollers inevitably require frequent replacements during use. This replacement process necessitates transporting the printing rollers from storage to the printing equipment. Due to their length and weight, these rollers often require significant manpower for handling and movement. Furthermore, their length can cause instability and swaying, potentially damaging them. Therefore, designing a flexible and stable printing roller handling device suitable for use in printing plants would greatly increase the efficiency of roller handling and replacement, and significantly reduce the probability of damage. Utility Model Content

[0004] The purpose of this invention is to provide a mobile transport vehicle for handling printing rollers, which has the advantages of being more efficient, stable and less prone to damage during the handling process.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A mobile transport vehicle for handling printing rollers includes a base, a support, a transport mechanism, and a centering mechanism. The base is located at the bottom, the support is located on the upper part of the base, the transport mechanism moves on the support, and the centering mechanism is located in the middle of the transport mechanism. The transport mechanism includes a horizontal support frame, a vertical support frame, an arc-shaped support plate, and a moving mechanism. The vertical part of the support frame has a sliding groove, and both ends of the vertical support frame slide up and down within the sliding groove. The side of the horizontal support frame near the support is welded and fixed to the top of the vertical support frame. The moving mechanism drives the horizontal support frame to move up and down. The arc-shaped support plate is fixed to the side of the horizontal support frame away from the support. The centering mechanism is fixed to the upper part of the vertical support frame.

[0006] Preferably, the moving mechanism includes a T-frame, a cable, and a winch. The T-frame is horizontally positioned and fixed to one side of the support. The winch is fixed to the side of the T-frame away from the support. A guide wheel is fixed upside down at the top of the support. The cable passes through the guide wheel, with one end wound and loosened by the winch, and the other end passing through the centering mechanism to secure the connection between the horizontal support frame and the vertical support frame.

[0007] Preferably, the centering mechanism includes a base and a fixing ring. The base is fixed to the middle of the vertical support frame. The fixing ring includes two outer rings and one inner ring. The two outer rings are vertically fixed to the upper part of the base. The inner ring is fixed at a distance from the upper part of the outer rings. The inner ring is fixedly connected to the inner side of the outer rings. The cable passes through the middle of the inner ring and the outer ring.

[0008] Preferably, a reinforcing structure is fixedly connected to the middle of the horizontal support frame. The reinforcing structure includes a horizontal bar and a diagonal bar. The horizontal bar is horizontally arranged and its two ends are fixed to the horizontal support frame. There are two diagonal bars arranged symmetrically. One end of the diagonal bar is fixed to the middle of the horizontal support frame, and the other end is fixed to the bottom of the vertical support frame.

[0009] Preferably, a rubber gasket is fixedly connected to the inner wall of the arc-shaped support plate.

[0010] Preferably, the lower part of the base is provided with pulleys.

[0011] Preferably, the winch can be driven by a motor.

[0012] Preferably, the winch can be manually driven by a handle.

[0013] By employing the above technical solution, the horizontal support frame and vertical support frame of the transport mechanism are moved up and down together through the cooperation of the winch and cable of the moving mechanism. The handle pushes the transport vehicle according to the position where the printing roller needs to be replaced, allowing the entire transport vehicle to move under the guidance of pulleys to the required position of the printing roller. Then, based on the height of the printing roller, the moving mechanism is adjusted so that the winch drives the cable to move, and then the cable drives the entire transport mechanism to move further, allowing the printing roller to reach a convenient installation height. During the movement and transport, the central centering mechanism ensures that the long horizontal support frame and the printing roller remain balanced, preventing swaying and tipping due to imbalance during operation, which could damage the printing roller or injure workers.

[0014] The beneficial effects of this application are as follows: 1. The lifting and lowering of the conveying mechanism is simple, highly stable, and accurately positioned using a winch and cable; 2. The use of two supports, a horizontal bearing frame and a vertical support frame, makes the entire frame more robust and provides more stable support and operation for the printing roller; 3. The cooperation between the fixing ring of the centering mechanism and the cable ensures that the cable remains in the center of the conveying mechanism during transport, thus preventing the long printing roller from tipping over due to imbalance and improving the stability of the transport.

All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.

[0018] See Figures 1 to 3 A mobile transport vehicle for handling printing rollers, with attachment Figure 1 As shown, the system includes a base 1, a support 3, a transport mechanism, and a centering mechanism. The base 1 is located at the bottom, the support 3 is located on top of the base 1, the transport mechanism moves on the support 3, and the centering mechanism is located in the middle of the transport mechanism and fixed to the upper part of the vertical support frame 10. The handling mechanism includes a horizontal support frame 6, a vertical support frame 10, an arc-shaped support plate 7, and a moving mechanism. The vertical part of the support frame 3 has a sliding groove. The two ends of the vertical support frame 10 slide up and down in the sliding groove. The horizontal support frame 6 is welded and fixed to the top of the vertical support frame 10 on the side near the support frame 3. The moving mechanism drives the horizontal support frame 6 to move up and down.

[0019] With attachment Figure 2 As shown, the moving mechanism includes a T-frame 5, a cable 11, and a winch 12. The T-frame 5 is horizontally positioned and fixed to one side of the support 3. The winch 12 is fixed to the side of the T-frame 5 away from the support 3. A guide wheel 15 is fixed upside down on the top of the support 3. The cable passes through the guide wheel 15, with one end wound and loosened by the winch 12, and the other end passing through the central mechanism to tie and fix the connection between the horizontal support frame 6 and the vertical support frame 10.

[0020] With attachment Figure 3As shown, the centering mechanism includes a base 16 and a fixing ring. The base 16 is fixed to the middle of the vertical support frame 10. The fixing ring includes two outer rings 17 and one inner ring 18. The two outer rings 17 are vertically fixed to the upper part of the base 16, and the inner ring 18 is fixed to the upper part of the outer rings 17 at a distance. The inner ring 18 and the inner side of the outer rings 17 are fixedly connected. The cable 11 passes through the middle of the inner ring 18 and the outer rings 17.

[0021] When the printing roller needs to be fed, the cable 11 is first driven by the winch 12. The cable 11 passes through the guide wheel 15 and through the fixing ring, and is tied and fixed at the connection between the horizontal support frame 6 and the vertical support frame 10. At this time, due to the fixing effect of the fixing ring, the cable 11 is always located in the middle of the horizontal support frame 6 and the vertical support frame 10, so that the horizontal support frame 6 and the vertical support frame 10 will not tilt even if the length is long, which greatly improves the stability of the printing roller when it moves up and down.

[0022] The drive source for the winch 12 here can be driven by the motor 14 or manually driven by the handle 13. Both manual and motor 14 drives can enable the winch 12 to reel in and unload the cable 11.

[0023] With attachment Figure 1 As shown, the arc-shaped support plate 7 is fixed to the side of the horizontal support frame 6 away from the bracket 3. A rubber pad is fixedly connected to the inner wall of the arc-shaped support plate 7. By setting the rubber pad inside the arc-shaped support plate 7, the friction between the two ends of the printing roller and the horizontal support frame 6 is increased, which prevents the printing roller from slipping out due to insufficient friction with the horizontal support frame 6 during movement. The rubber pad also has a buffering effect, which prevents the printing roller from colliding with the horizontal support frame 6 and causing damage.

[0024] A reinforcing structure is fixedly connected in the middle of the horizontal support frame 6. The reinforcing structure includes a horizontal bar 8 and a diagonal bar 9. The horizontal bar 8 is set horizontally, and both ends of the horizontal bar 8 are fixed to the horizontal support frame 6. There are two diagonal bars 9, which are set symmetrically. One end of the diagonal bar 9 is fixed to the middle of the horizontal support frame 6, and the other end is fixed to the bottom of the vertical support frame 10. By reinforcing the horizontal support frame 6, its stability and load-bearing capacity are improved, and the instability of the entire horizontal support frame 6 due to excessive pressure or the weight of the printing roller is avoided.

[0025] The base 1 is equipped with pulleys 2 at the bottom. By setting pulleys 2 at the bottom of the base 1, the entire transport vehicle can move flexibly, not only moving the printing roller up and down, but also moving it to different places.

[0026] This invention utilizes a winch 12 and cable to move the horizontal support frame 6 and vertical support frame 10 of the transport mechanism up and down together. The handle pushes the transport vehicle to the desired location of the printing roller, guided by pulleys 2. During movement and transport, the central mechanism ensures the balance between the longer horizontal support frame 6 and the printing roller, preventing swaying and tipping due to imbalance and potential damage to the printing roller or injury to workers. This improves both the efficiency and stability of the printing roller transport process.
