DETAILED DESCRIPTION
[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] like Figure 1-4 As shown, an adjustable loading device comprises a linear drive device 12, a loading trolley 5, a drive device and multiple groups of frames 2, two mounting platforms 201 of the multiple groups of frames 2 are respectively installed with oblique sliding components 3, two oblique sliding components 3 on the frames 2 are respectively connected with loading racks 8, the loading racks 8 extend to multiple frames 2 and are respectively connected to the second inclined sliders 302 of multiple oblique sliding components 3, two groups of loading racks 8 form a conveying channel for tube embryos, the driving end of the linear drive device 12 is connected to the loading rack 8 at the starting end of loading through a connecting plate 13, the loading rack 8 is fixedly connected to the two loading racks 8 on this frame 2, the moving path of the output end of the linear drive device 12 is the same as the sliding path angle of the oblique sliding component 3, a push rod 7 is fixed on the loading trolley 5, the top of the push rod 7 is located in the conveying channel, and the drive device is used to drive the loading trolley 5 to move horizontally to convey the tube embryos in the push rod 7 conveying channel.
[0024] In this embodiment, if Figure 1 and Figure 2 As shown, according to the specifications of the tube embryo, the linear drive device 12 is controlled to work so that it applies a moving force to the two groups of loading racks 8, so that the two groups of loading racks 8 change their own heights under the action of the oblique sliding components 3, and then the gantry lifts the tube embryo to the conveying channel formed by the two groups of loading racks 8. At this time, the push rod 7 connected to the loading trolley 5 contacts the end of the tube embryo. Therefore, when the driving device drives the loading trolley 5 to move, the loading trolley 5 will push the tube embryo to move through the push rod 7, thereby ensuring that the tube embryo can smoothly enter the tube rolling mill.
[0025] Among them, Figure 1 and Figure 2As shown, the oblique sliding assembly 3 includes a first inclined slider 301 fixed on the mounting platform 201, and a second inclined slider 302 matching with the first inclined slider 301 slides on the first inclined slider 301, and baffles 303 are arranged on both sides of the first inclined slider 301 and the second inclined slider 302, and the baffles 303 are fixed on the top of the mounting platform 201; the second inclined slider 302 can slide relative to the first inclined slider 301, and the second inclined slider 302 is always in a vertical state, and the two baffles 303 can limit the sliding path of the second inclined slider 302, so when the linear drive device 12 applies force to the loading rack 8, the second inclined slider 302 slides on the inclined surface of the first inclined slider 301, thereby changing the height of the loading rack 8, and then the conveying channel formed by the two loading racks 8 can directly deliver the pipe blanks of corresponding specifications into the pipe rolling machine.
[0026] Among them, Figure 1 As shown, a positioning plate 10 is provided at the low point of the first inclined slider 301 of at least one set of the frame body 2, the positioning plate 10 is fixedly connected to the baffle 303, and a bolt 14 for resisting the second inclined slider 302 is threadedly connected to the positioning plate 10, as shown in FIG. Figure 4 As shown, when the position of the second inclined slider 302 is determined, personnel can rotate the bolt 14 so that one end of the bolt 14 abuts against the second inclined slider 302, thereby improving the position stability of the second inclined slider 302 and reducing the possibility of the second inclined slider 302 changing its position when conveying the tube blank.
[0027] Among them, Figure 1 and Figure 2 As shown, a limiting frame 9 is fixed on one side of one group of loading racks 8 on the frame 2, the frame 2 is triangular, and the adjacent oblique sides of the two frames 2 form a conveying channel. When the gantry frame lifts the tube embryo into the conveying channel, the tube embryo should be placed as close to the center of the conveying channel as possible. If it cannot be precisely controlled, the tube embryo can be biased toward the loading rack 8 that is not connected to the limiting frame 9. At this time, if the tube embryo rolls, it will roll toward the loading rack 8 connected to the limiting frame 9 because the oblique side of this loading rack 8 is facing the other loading rack 8. Therefore, the limiting frame 9 can limit the tube embryo and prevent the tube embryo from leaving the conveying channel.
[0028] Among them, Figure 1 and Figure 3As shown, the driving device includes a tailstock 15 and a rotary driving device 1 respectively located at the starting end and the end end of the conveying, the tailstock 15 is rotatably connected to a driven sprocket 11, the rotary driving device 1 is connected to the driven sprocket 11 through a chain 6, and two groups of U-shaped plates 4 with openings opposite to each other are respectively arranged between the two groups of oblique sliding components 3 on the frame 2, the loading trolley 5 is located in the U-shaped plate 4 and the rollers of the loading trolley 5 are in contact with the inner wall of the U-shaped plate 4, so the two U-shaped plates 4 can limit the conveying path of the loading trolley 5, and the bottom of the loading trolley 5 is fixedly connected to the chain 6, so when the rotary driving device 1 drives the chain 6 to transmit, the loading trolley 5 will move accordingly, thereby pushing the tube blank in the conveying channel to perform the loading operation, the loading trolley 5 and the driving device driving the loading trolley 5 to move through the chain 6 are both prior arts in the field, and no further elaboration is given here.
[0029] Among them, Figure 1 As shown, the linear drive device 12 is fixed on the tailstock 15, and the linear drive device 12 is an electric cylinder or a hydraulic cylinder. The rotary drive device 1 includes a motor 101 and a reducer 102 connected to the drive shaft of the motor 101, and the output shaft of the reducer 102 is connected to a drive sprocket 103, and the drive sprocket 103 is connected to the chain 6.
[0030] Among them, Figure 1 As shown, the U-shaped plate 4 extends onto the multiple frames 2 and the U-shaped plate 4 is fixedly connected to the mounting platforms 201 of the multiple frames 2, thereby ensuring that the loading trolley 5 is transported along a prescribed path.
[0031] Working principle: when the linear drive device 12 is working, its output end will apply a moving force to the two sets of loading racks 8, thereby driving the second inclined plane slider 302 to slide on the inclined plane of the first inclined plane slider 301, and then changing the height of the loading rack 8 so that the height of the conveying channel meets the requirements. Then, the personnel rotate the bolt 14 so that one end of it abuts against the second inclined plane slider 302, thereby improving the position stability of the second inclined plane slider 302. In the next step, the gantry crane is used to place the pipe embryo into the conveying channel, and it is ensured that the push rod 7 connected to the loading trolley 5 is located at the end of the pipe embryo away from the pipe rolling mill. Then, the motor 101 starts to work, and the motor 101 will drive the driving sprocket 103 to rotate through the reducer 102, so that the chain 6 is driven under the action of the driven sprocket 11, and then the loading trolley 5 is driven along with the chain 6, so that the loading trolley 5 can send the pipe embryo in the conveying channel into the pipe rolling mill through the push rod 7.
