[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Combine the following Figure 1-Figure 8 , a printing device transport vehicle provided by an embodiment of the present invention is described in detail through specific embodiments and application scenarios.

[0030] like Figure 1 and Figure 2As shown, the present invention provides a printing device transport vehicle, comprising: a pallet 1, a moving seat 2, a connecting plate 3, a movable vehicle body 4 and a linear drive mechanism 5. The pallet 1 is arranged horizontally and is used to place the printing device. One end of the pallet 1 is fixed to the moving seat 2, and the connecting plate 3 is supported between the moving seat 2 and the pallet 1. The linear drive mechanism 5 is installed on the movable vehicle body 4, and the linear drive mechanism 5 is transmission-connected to the moving seat 2, and is used to drive the moving seat 2 to rise and fall.

[0031] It is understandable that the printing device transport vehicle provided by the present invention can easily transport the printing device to each corresponding area, saving time and effort, and greatly liberating manual labor.

[0032] Specifically, Figure 1 and Figure 2 As shown, the pallet 1 is rectangular. The size of the pallet 1 is greater than or equal to the size of the bottom surface of the printing device. Optionally, the size of the pallet 1 is 360mm*550mm. The driving end of the linear drive mechanism 5 is connected to the moving seat 2 to drive the moving seat 2 to move in the vertical direction. The pallet 1 is fixed to the moving seat 2, so that the printing device on the pallet 1 is driven to rise or fall by the moving seat 2.

[0033] In a specific application scenario, the installation platform of the printing device is 673 mm from the ground. The linear drive mechanism 5 can control the pallet 1 to move within a height range of 600 mm to 850 mm from the ground, so as to ensure that the operator has sufficient operating space when installing or repairing the printing device, thereby improving the convenience of repair. Preferably, during repair, the height of the pallet 1 can be controlled to 805 mm from the ground by the linear drive mechanism 5.

[0034] like Figure 3 As shown, the support plate 1 and the moving seat 2 are arranged vertically. The support plate 1 can be fixed to the moving seat 2 by bolts, or the support plate 1 and the moving seat 2 are an integral structure. Figure 3 and Figure 4 As shown, a connecting plate 3 is further provided between the pallet 1 and the movable seat 2. The connecting plate 3 is tilted, and the two ends of the connecting plate 3 are respectively fixedly connected to the movable seat 2 and the pallet 1 to form support for the pallet 1, thereby ensuring that the pallet 1 has sufficient supporting strength.

[0035] When the printing device needs to be removed from the mounting platform, the linear drive mechanism 5 drives the movable seat 2 to rise to a certain height to ensure that the pallet 1 is just flush with the bottom surface of the printing device. After the printing device is stably placed on the pallet 1, the linear drive mechanism 5 drives the movable seat 2 to descend, so that the pallet 1 descends toward the ground, and then the printing device is transferred to the target area by the movable vehicle body 4.

[0036] When the printing device needs to be moved from the storage area to the installation table for installation, it is only necessary to transfer the printing device to the bottom of the installation table through the movable body 4, and then drive the movable seat 2 to rise to the height of the installation table through the linear drive mechanism 5, and then the printing device can be transported to the installation table.

[0037] The present invention provides a printing device transport vehicle, in which a linear drive mechanism 5 can drive a moving seat 2 to rise and fall, and the moving seat 2 drives a pallet 1 to rise and fall, a connecting plate 3 is supported between the moving seat 2 and the pallet 1 to ensure that the pallet 1 has sufficient lifting strength for the printing device, and the printing device can follow the pallet 1 to rise to a mounting platform or descend to the ground; the printing device is transferred to a target area through a movable vehicle body 4, without the need for manual transport, thus saving time and effort, eliminating the safety hazards of manual transport, and greatly improving the installation or maintenance efficiency of the printing device.

[0038] In some embodiments, Figure 5 As shown, the other end of the support plate 1 is convexly provided with a connecting edge 11. The connecting edge 11 is used to guide the printing device to smoothly transition from the support plate 1 to the mounting platform, or to guide the printing device to smoothly transition from the mounting platform to the support plate 1.

[0039] In some scenarios, the maximum specification of the printing device is 550mm*340mm. Among them, 550mm is the length of the printing device along the moving direction of the movable body 4. 340mm is the length of the printing device perpendicular to the moving direction of the movable body 4. Optionally, the length of the pallet 1 in the moving direction of the movable body 4 is greater than or equal to 550mm, and the length of the pallet 1 perpendicular to the moving direction of the movable body 4 is greater than or equal to 360mm. The connecting edge 11 is protruded from the central area of ​​one end of the pallet 1. The length of the connecting edge 11 perpendicular to the moving direction of the movable body 4 can be 250mm.

[0040] By providing a connecting edge 11 at one end of the pallet 1 away from the moving seat 2, the printing device can smoothly transition between the pallet 1 and the mounting platform. When the printing device needs to be moved from the mounting platform to the ground for maintenance, the bottom surface of the printing device and the connecting edge 11 slide in contact, and the printing device can be smoothly moved to the pallet 1. Similarly, when the printing device needs to be moved from the pallet 1 to the mounting platform, the bottom surface of the printing device and the connecting edge 11 slide in contact, and the printing device can be smoothly moved to the mounting platform.

[0041] In some embodiments, Figure 6 As shown, the linear drive mechanism 5 includes an operating handle 31 and a screw assembly 32. The screw 321 of the screw assembly 32 is rotatably mounted on the movable body 4 through a bearing. The movable seat 2 and the nut 322 in the screw assembly 32 are fixedly connected, and the operating handle 31 and the screw 321 in the screw assembly 32 are transmission-connected.

[0042] It is understandable that the axis of the lead screw 321 of the lead screw assembly 32 is parallel to the vertical direction. The operating handle 31 is fixedly connected to the end of the lead screw 321. The user manipulates the operating handle 31, and the operating handle 31 drives the lead screw 321 to rotate, so that the nut 322 drives the moving seat 2 to move linearly along the axial direction of the lead screw 321, so that the support plate 1 can lift the printing device, and the printing device can be raised and lowered within a preset height range, avoiding manual handling and reducing the difficulty of handling for operators.

[0043] like Figure 7 As shown, the printing device transport vehicle provided by the present invention further includes a slide rail 6 and a slider 7. One of the slide rail 6 and the slider 7 is fixed to the movable seat 2, and the other is fixed to the movable vehicle body 4. The slide rail 6 extends in the vertical direction, and the slider 7 is slidably arranged on the slide rail 6.

[0044] Optional, such as Figure 1 As shown, the slide rail 6 is provided on the movable body 4 and extends in the vertical direction. The slider 7 is fixed to the side of the movable seat 2 close to the movable body 4. The slider 7 is slidably provided on the slide rail 6 to guide the movable seat 2 to rise and fall smoothly in the vertical direction. In the vertical direction, a plurality of sliders 7 can be fixed on the movable seat 2, and the plurality of sliders 7 are movably provided on the slide rail 6 respectively to further ensure that the movable seat 2 can rise and fall smoothly.

[0045] Of course, the slide rails 6 may be provided on the movable seat 2 and the sliders 7 may be provided on the movable body 4, as long as it is ensured that the movable seat 2 can be lifted and lowered smoothly.

[0046] In some embodiments, the slide rail 6 and the slider 7 are provided in a set, and the two sets of slide rails 6 and the slider 7 are symmetrically arranged on opposite sides of the linear drive mechanism 5 along the vertical direction to further ensure the stability of the moving seat 2 when it is lifted or lowered.

[0047] In some embodiments, Figure 2 As shown, the movable vehicle body 4 includes a base 41, a moving wheel 42, a steering wheel 43, and a frame 44 vertically fixed to one side of the base 41. The linear drive mechanism 5 is mounted on the frame 44, the moving wheel 42 and the steering wheel 43 are rotatably mounted below the base 41, and the steering wheel 43 is located behind the moving wheel 42 and is provided with a brake member 431.

[0048] It is understandable that if Figure 2 As shown, the frame 44 is arranged vertically. The bottom of the frame 44 is fixed to one side of the base 41. Optionally, the frame 44 and the base 41 can be an integral structure. Alternatively, the bottom of the frame 44 can be fixed to one side of the base 41 by a locking member such as a screw. The linear drive mechanism 5 is used to drive the moving seat 2 to rise and fall along the height direction of the frame 44.

[0049] The moving wheels 42 can be rotatably mounted on the lower side of the base 41 through the bearing seat. Optionally, the moving wheels 42 have at least one pair. The same pair of moving wheels 42 is symmetrically mounted on opposite sides of the base 41 along the traveling direction of the movable vehicle body 4. Figure 2 As shown, the steering wheel 43 is located behind the moving wheel 42. The steering wheel 43 can be connected to the base 41 by a steering connector so as to control the moving direction of the movable vehicle body 4 by the steering wheel 43.

[0050] like Figure 2 As shown, the steering wheel 43 is provided with a brake member 431, and the brake member 431 is used to limit the movement of the steering wheel 43. When the printing device is in the process of being raised or lowered, the brake member 431 can limit the movement of the entire transport vehicle to ensure the stability of the printing device during the raising or lowering.

[0051] like Figure 2 As shown, the support plate 1 is located above the base 41 , and one end of the support plate 1 away from the moving base 2 extends out of the base 41 .

[0052] It is understandable that due to the space limitation of other structures in the processing workshop, the base 41 cannot completely reach the foot of the wall of the mounting table, that is, there is a certain gap between the base 41 and the wall of the mounting table. Extending the end of the pallet 1 away from the movable seat 2 out of the base 41 can ensure that the pallet 1 can be overlapped to the mounting table, eliminating the gap between the movable body 4 and the mounting table, so that the printing device can be directly dragged from the pallet 1 to the mounting table, or the printing device can be directly dragged from the mounting table to the pallet 1 to prevent the printing device from overturning.

[0053] In a specific application scenario, the base 41 can be moved to a minimum distance of 100 mm from the wall of the mounting platform. Optionally, when the length of the pallet 1 extending out of the base 41 is 100 mm to 540 mm and the total weight of the tool cart is 78 kg to 82 kg, it can ensure that the pallet 1 can be overlapped to the mounting platform and the entire transport vehicle has sufficient weight to prevent the transport vehicle from tilting due to the excessive weight of the printing device.

[0054] Furthermore, in some embodiments, Figure 1 and Figure 8 As shown, the printing device transport vehicle provided by the present invention further includes at least one stopper 8. The stopper 8 extends in the horizontal direction, is fixed to the movable vehicle body 4, and is located above the outer edge of the pallet 1. The stopper 8 is used to prevent the printing device from sliding off the outer edge of the pallet 1.

[0055] It is understandable that if Figure 1As shown, the stopper 8 is in the shape of a long strip. The stopper 8 extends along the traveling direction of the movable body 4. One end of the stopper 8 is fixed to the top of the movable body 4, and the stopper 8 is cantilevered from the movable body 4. By arranging the stopper 8 above the outer edge of the pallet 1, the side of the pallet 1 is limited to prevent the printing device from tipping over from the side of the pallet 1 during the lifting process.

[0056] like Figure 8 As shown, the printing device transport vehicle provided by the present invention further includes a fastener 9. The stopper 8 is provided with a strip hole 81 extending in the horizontal direction. The movable vehicle body 4 is provided with a first mounting hole, and the fastener 9 is sequentially inserted into the strip hole 81 and the first mounting hole to fix the stopper 8 to the movable vehicle body 4.

[0057] It is understandable that the fastener 9 is sequentially inserted into the first mounting hole and the strip hole 81 to achieve the goal of firmly fixing the stopper 8 on the movable vehicle body 4. Optionally, the fastener 9 is a butterfly bolt.

[0058] When the length of the printing device in the direction of travel of the movable body 4 changes, loosen the fastener 9 and move the stopper 8 so that the fastener 9 is located at a suitable position in the strip hole 81, and then lock the stopper 8 on the movable body 4 through the fastener 9 to adjust the length of the stopper 8 cantilevered from the movable seat 2, thereby ensuring that the stopper 8 can adapt to the length of the printing device in the direction of travel of the movable body 4 to form an effective limit on the side of the pallet 1.

[0059] like Figure 8 As shown, the printing device transport vehicle provided by the present invention further includes a fixing member 10. The end of the stopper 8 close to the movable vehicle body 4 has a connecting portion 82. The connecting portion 82 is provided with a waist-shaped hole 821 extending in the vertical direction. The movable vehicle body 4 is provided with a second mounting hole, and the fixing member 10 is sequentially inserted into the waist-shaped hole 821 and the second mounting hole to fix the connecting portion 82 to the movable vehicle body 4.

[0060] It is understandable that, in this embodiment, the fixing member 10 is sequentially inserted into the second mounting hole and the waist-shaped hole 821 to achieve the goal of firmly fixing the stopper 8 on the movable vehicle body 4. Optionally, the fixing member 10 is a butterfly bolt.

[0061] When the height of the printing device changes, loosen the fixing part 10 and move the stopper 8 so that the fixing part 10 is located at a suitable position of the waist-shaped hole 821, and then lock the stopper 8 on the movable body 4 through the fixing part 10 to adjust the height of the stopper 8 relative to the pallet 1 to ensure that the stopper 8 can adapt to the height of the printing device, thereby forming an effective limit for the printing device on the side of the pallet 1.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
