The length direction of the flip plate 1 is parallel to the mounting plate 51. The bottom of the mounting plate 51 is provided with a walking wheel 52, which is convenient for moving the mounting plate 51 and improving the convenience of use of the flip device; the longitudinal adjustment mechanism 6 is arranged on the base 3 and is used to adjust the height of the flip plate 1 and the driving part 2 in a direction perpendicular to the mounting plate 51; the power distribution component 7 is arranged on the mounting plate 51 and is used to power the driving part 2 and the walking wheel 52. The power distribution component 7 is used to power the flip device, so that the flip device is not constrained by cables, can be walked anywhere, is easy to use, and improves the convenience and flipping efficiency of the flip device.

[0029] Specifically, Figure 1~Figure 2 As shown, the base 3 includes a bottom plate 31 arranged parallel to the mounting plate 51, and a first orifice plate 32 is vertically arranged on the bottom plate 31. The driving part 2 includes a motor 21 and a reducer 22, the driving end of the motor 21 is connected to the input end of the reducer 22, the output end of the reducer 22 is installed on the side of the first orifice plate 32, and the input shaft of the reducer 22 passes through the first orifice plate 32 and is connected to the bottom of the flip plate 1. Through the arrangement of the reducer 22, it can be ensured that the motor 21 outputs sufficient torque to ensure stable and effective flipping of the flip plate 1.

[0030] Preferably, Figure 1~Figure 3As shown, a second orifice plate 33 is provided parallel to one side of the first orifice plate 32, mounting holes 321 are provided at both ends of the first orifice plate 32, and waist-shaped holes 331 are provided at both ends of the second orifice plate 33, each waist-shaped hole 331 is arranged in a direction perpendicular to the mounting plate 51, and a guide bolt 332 is passed through the waist-shaped hole 331, and the front end of the guide bolt 332 is threadedly connected to the mounting hole 321, and a limiting plate 333 is provided at the rear end thereof. As the guide bolt 332 is screwed in, the limiting plate 333 abuts against one side of the second orifice plate 33, thereby installing the second orifice plate 33 on one side of the first orifice plate 32. At the same time, through the cooperation of the guide bolt 332 and the waist-shaped hole 331, the second orifice plate 33 has a moving line in a direction perpendicular to the mounting plate 51; the output end of the reducer 22 is installed on the side of the second orifice plate 33, and the output shaft of the reducer 22 is set through the second orifice plate 33. The installation structure of the first orifice plate 32, the second orifice plate 33 and the reducer 22 has a compact layout and high stability. At the same time, the flip plate 1 has a longitudinal adjustment stroke, which facilitates the installation and docking of the flip plate 1 with the straight tube screen, and improves the flexibility and convenience of the flip device.

[0031] Specifically, Figure 1~Figure 4 As shown, the longitudinal adjustment mechanism 6 includes a support plate 61 vertically arranged on the first orifice plate 32 and located below the second orifice plate 33, and the support plate 61 is threaded with an adjustment screw 62 arranged vertically to the mounting plate 51. When it is necessary to adjust the longitudinal height of the flip plate 1, the adjustment screw 62 is turned, and one end of the adjustment screw 62 will lift or lower the second orifice plate 33, thereby driving the reducer 22 and the motor 21 installed on the second orifice plate 33 to move longitudinally, thereby realizing the adjustment of the longitudinal height of the flip plate 1. The longitudinal adjustment mechanism 6 is simple to install, low in cost, and can effectively realize the adjustment function of the longitudinal height of the flip plate 1. At the same time, during the production process, the longitudinal height of the flip plate 1 can be adjusted according to the actual position of the straight tube screen, which is conducive to improving the applicability and convenience of the flip device.

[0032] Specifically, Figure 1 and Figure 2 As shown, the transverse movement mechanism 4 includes a linear mechanism 41 arranged on the mounting plate 51, a movable end of which is arranged toward the length direction of the flip plate 1 and is connected to the bottom of the base 3 through a connecting bracket 42. The linear mechanism 41 can be in the form of a linear cylinder, an electric cylinder, an electric push rod, etc.; the mounting plate 51 is also provided with a guide rail 43 arranged toward the length direction of the flip plate 1, and a slider 44 is provided under the bottom plate 31, and the slider 44 is slidably fitted on the guide rail 43.

[0033] Preferably, Figure 1 and Figure 2As shown, the support part 11 includes a plurality of cylindrical pins 13 arranged at one end of the flip plate 1 and perpendicular to the flip plate 1, and each cylindrical pin 13 is arranged in an array along the length direction of the flip plate 1. During the flipping process of the flip plate 1, the cylindrical pins 13 can effectively support the straight tube panel, and the assembly and disassembly are simple, which is convenient for the maintenance of the flip device.

[0034] The general flip device needs to be connected with cables to power its various driving parts. The cable length is limited, which will directly affect the use range of the flip device. At the same time, the cable will also hinder the movement of the flip device, thereby reducing the flexibility and convenience of the flip device. Figure 1 and Figure 2 As shown, in this embodiment, the power distribution assembly 7 includes a battery support cabinet 71 arranged on the mounting plate 51, in which multiple batteries can be installed and connected in series to power the walking wheels 52 and the motor 21, eliminating the constraints of the power supply cables on the flipping device, so that the flipping device can be moved anywhere, effectively expanding its working range, and improving the flexibility and convenience of the flipping device. At the same time, the battery-powered mode is also more environmentally friendly and safe.

[0035] Specifically, Figure 1 and Figure 2 As shown, the walking wheel 52 includes a directional wheel and a universal drive wheel. A multifunctional handle 9 is provided on one side of the mounting plate 51, on which various function buttons are integrated. By cooperating with the power distribution component 7, the forward, backward, braking, turning, acceleration, deceleration, emergency stop and other functions of the flip device are realized, which further improves the flexibility and convenience of the flip device. At the same time, when using the flip device, the operator only needs to hold the multifunctional handle to move the flip and control the flipping of the flip plate 1, so that when flipping the straight tube screen, the operator is at a safe distance, which can effectively ensure the safety of the operator.

[0036] Preferably, Figure 3 and Figure 5 As shown, travel switches 34 can be set at both ends of the first orifice plate 32, and the other end of the flip plate 1 is provided with a touch plate 12 that cooperates with the limit switch 34. The limit switch 34 in this embodiment is a roller type. When the touch plate 12 touches the roller of the limit switch 34, the motor 21 stops running. Through the cooperation of the limit switch 34 and the touch plate 12, the flipping of the straight tube screen can be positioned more accurately, ensuring the reliability and safety of the flipping device and improving the flipping efficiency.

[0037] To further ensure the reliability and safety of the flip device and improve redundancy, Figure 3 and Figure 5As shown, a pair of limit rods 35 can be vertically arranged on the bottom plate 31 and are respectively located at the two ends of the first orifice plate 32. When the flip plate 1 flips, the limit rods 35 can resist the flip plate 1 to limit the flip angle of the straight tube panel. When the limit switch 34 fails, the limit rods 35 can still effectively limit the flip plate 1 to ensure the safe flipping of the straight tube panel.

[0038] The present invention also discloses a flipping method of the flipping device as described above, such as Figure 6~Figure 12 As shown, the following steps are included: S01, such as Figure 6 As shown, the straight tube panels are horizontally placed on the rack 8 in sequence, with the end of the straight tube panel extending 300mm to 400mm from one side of the rack 8, and the two flip plates 1 are in a horizontal state. The operator holds the multifunctional handle and moves the flip device by operating each function button, so that the opening on the other side of the flip plate 1 is aligned with the end of the straight tube panel, and the opening end face of the flip plate 1 is about 50mm away from the end face of the straight tube panel; S02, such as Figure 6 As shown, by turning the adjusting screw 62, one end of the adjusting screw 62 will lift or lower the second orifice plate 33, so that the flip plate 1 located below is about 5 mm lower than the upper surface of the rack 8, as shown in FIG. Figure 8 As shown, the rotation axis of the flip plate 1 is located above the upper surface of the rack 8, and the distance between the rotation axis of the flip plate 1 and the cylindrical pin 13 is greater than the distance between the rotation axis of the flip plate 1 and the upper surface of the rack 8; S03, such as Figure 7 As shown, the linear mechanism 41 is extended to drive the base 3 along the guide rail 43 to approach the end of the straight tube panel through the connecting frame 42, so that the straight tube panel is inserted into two-thirds of the two flip plates 1; S04, operate the multi-function button, the power distribution component 7 supplies power to the motor 21, the torque output by the motor 21 is increased by the reducer 22 and transmitted to the flip plate 1. At this time, the straight tube screen is supported by the positioning pin 13, the flip plate 1 and the material rack 8, and flips with the rotation of the motor 21; S05, such as Figure 3 , Figure 5 , Fig.12 As shown, until the touch plate 12 on the flip plate 1 touches the limit switch 34 at one end of the first orifice plate 32, the motor 21 stops rotating, and the straight tube panel flips 180°. The linear mechanism 41 is operated to retract, and the flip plate 1 is withdrawn from the end of the straight tube panel; and the multi-function button is operated to drive the flip plate 1 to rotate in the opposite direction by the motor 21, until the touch plate 12 touches the limit switch 34, the motor 21 stops running, and the flip plate 1 returns to the initial state. The flipping of one straight tube panel is completed, and steps S01 to S05 are repeated to flip the next straight tube panel.

[0039] Specifically, Figure 6~Figure 12As shown, since the bottom surface of the opening of the flip plate 1 is about 5 mm lower than the upper surface of the rack 8, when the straight tube panel enters the flip plate 1, the entire weight of the straight tube panel is supported by the rack 8; Figure 8 and Fig. 9 As shown, since the rotation axis of the flip plate 1 is located above the upper surface of the rack 8, and the distance between the rotation axis of the flip plate 1 and the cylindrical pin 13 is greater than the distance between the rotation axis of the flip plate 1 and the upper surface of the rack 8, when the flip plate 1 drives the straight tube panel to rotate 30° from the initial state, a part of the cylindrical pins 13 begins to enter below the upper surface of the rack 8, and the support mode of the straight tube panel is changed from being fully supported by the rack 8 to one end of the straight tube panel being supported by one of the flip plates 1, and the other end of the straight tube panel being supported by the rack 8 and the cylindrical pins 13, and the rack 8 bears a larger part of the gravity of the straight tube panel; Fig.10 As shown in FIG. 1 , when the flip plate 1 drives the straight tube panel to continue rotating from 30° to 90°, the cylindrical pin 13 will move to be completely located below the upper surface of the rack 8, and the straight tube panel will separate from the cylindrical pin 13. The support mode of the straight tube panel changes to being fully supported by the rack 8; Fig.11 As shown in the figure, when the flip plate 1 drives the straight tube panel to rotate from 90° to 120°, a part of the cylindrical pins 13 begin to return to the upper surface of the rack 8, and the support mode of the straight tube panel changes from being fully supported by the rack 8 to being supported by another flip plate 1 surface at one end of the straight tube panel, and being supported by the rack 8 and the cylindrical pins 13 at the other end. Similarly, the rack 8 bears a larger part of the gravity of the straight tube panel; Fig.12 As shown, when the flip plate 1 drives the straight tube panel to rotate from 120° to 180°, the straight tube panel will transition to being fully supported by the rack 8 and complete the flipping of the straight tube panel.

[0040] The straight tube screen is about 4m~16m long and weighs about 500kg~1000kg. It will be very time-consuming and laborious to flip it by manpower, and it has potential safety hazards. When flipping the straight tube screen, some other flipping devices may cause the flipping movement of the flipping device to interfere with the greater gravity and longer length of the straight tube screen, resulting in the flipping device tilting, overturning, and running around. This not only fails to flip the straight tube screen quickly and effectively, but also poses certain safety hazards to the operator due to the instability of the flipping device in flipping the straight tube screen.

[0041] The flip device is adapted to various specifications of straight tube screens through the structural setting of the flip plate 1. At the same time, with the cooperation of the longitudinal adjustment mechanism 6 and the transverse movement mechanism 4, the position of the flip plate 1 can be adjusted to improve the flexibility and applicability of the flip device. Under the action of the power distribution component 7, the flip device is freed from the constraints of the cables and has a larger range of activities and higher practicality. In addition, through the power supply of the power distribution component 7, in combination with the multi-function handle and the multi-function button, the operator can more quickly and simply control the movement of the flip device and the flipping of the flip plate 1. Such a driving and operating method is more environmentally friendly and has higher safety and convenience.

[0042] The flipping method of the flipping device coordinates the positions of the flipping plate 1, the material rack 8, and the cylindrical pin 13, so that during the flipping process of the straight tube panel, the weight or most of the weight of the straight tube panel is supported by the material rack 8, so that the flipping of the straight tube panel becomes time-saving and labor-saving, and further, the flipping of the straight tube panel can be achieved by only entering the flipping plate 1 at two-thirds of the distance. The flipping method is simple to operate and has a high flipping efficiency; at the same time, under the position coordination of the flipping plate 1, the material rack 8, and the cylindrical pin 13, the straight tube panel will not produce motion interference with the flipping plate 1, which can effectively solve the problems of tilting, overturning, and running around of the flipping device, has high flipping stability, and effectively ensures the safety of the operator.

[0043] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
