Detailed implementation manner

[0032] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation manners.

[0033] Such as Figures 1 to 3As shown in the figure, a steel bar framework welding device according to an embodiment of the present invention includes a base 1; a driving seat 2 is fixedly connected to one side of the base 1; a rotating tube 3 is rotatably connected to the side of the driving seat 2 close to the base 1, and the rotating tube 3 is driven by a servo motor; a plurality of 4 are evenly arranged on the surface of the rotating tube 3; a plurality of evenly arranged rotating arms 5 are rotatably connected between the pressing plate 4 and the rotating tube 3, and the rotating arms 5 are driven by a hydraulic system; a moving box 6 is slidably connected to the top surface of the base 1, and the moving box 6 is driven by a servo motor; a scissor-type telescopic frame 7 is arranged at the top of the moving box 6; one end of the scissor-type telescopic frame 7 is fixedly connected to the end of the moving box 6 close to the driving seat 2, and the other end is slidably connected to the surface of the moving box 6, and the scissor-type telescopic frame 7 is driven by a lead screw; hinge joints of the scissor-type telescopic frame 7 are all rotatably connected with connecting seats 8; the connecting seat 8 adjacent to the driving seat 2 is fixedly connected to the moving box 6, and the remaining connecting seats 8 are all slidably connected to the moving box 6; a fixing component is installed on the top surface of the connecting seat 8; the fixing component is used to fix the stirrup on the top of the connecting seat 8; a welding component is installed on one side of the base 1; the welding component is used to weld the main bars on the surface of the stirrup; during work, in order to conveniently weld the stirrup and the main bars together evenly, the embodiment of the present invention can be used. First, the user needs to drive the moving box 6 to slide on the base 1 so that it is no longer located at the bottom of the rotating tube 3. Then the user installs the required stirrup on the top surface of the connecting seat 8 through the fixing component. After that, the user drives the moving box 6 to move back to the bottom of the rotating tube 3. At this time, the stirrup on the connecting seat 8 will just pass through the rotating tube 3 and the pressing plate 4 on its surface. Then the user drives the scissor-type telescopic frame 7 to gradually extend through the lead screw. At this time, the scissor-type telescopic frame 7 will drive the connecting seat 8 thereon to move, and the distance between each stirrup will be evenly increased. Until the distance between the stirrups at the head and tail ends is the same as the length of the main bar, the user drives the rotating arm 5 to rotate through the hydraulic system, so that the rotating arm 5 drives the pressing plate 4 to press the inner side of the stirrup, thereby fixing the stirrup. Then the welding component places the main bar against the outer side of the stirrup, and then welds each stirrup and the main bar together through the welding component. After that, the driving seat 2 drives the rotating tube 3 to rotate, and the rotating tube 3 drives the stirrup and the welded main bar to rotate, so as to align the non-welded area of the stirrup with the welding component. Then the welding component repeats the previous welding operation until the main bar is evenly welded on the surface of the stirrup, thereby completing the welding of the steel bar framework. By driving the connecting seat 8 and the stirrup thereon to move through the scissor-type telescopic frame 7, the distance between each stirrup is the same, so that the stirrup can be evenly welded on the surface of the main bar, thus eliminating the need for the user to calculate according to the length of the main bar, enabling the user to weld the stirrup and the main bar together more quickly, and thereby improving the production efficiency.

[0034] As Figures 3 to 5As shown, the fixing component includes a receiving seat 9; the receiving seat 9 is installed on the top surface of the connecting seat 8 and is driven by a lifting component; a clamping groove 10 is formed on the top surface of the receiving seat 9, and the clamping groove 10 is arranged in a V shape; rotating rods 11 are rotatably connected to both sides of the receiving seat 9 on the top surface of the connecting seat 8, and the rotating rods 11 are symmetric about the receiving seat 9; a locking rod 12 is slidably connected to the surface of the rotating rod 11, and the locking rod 12 is arranged in an L shape; a first spring 13 is fixedly connected between the locking rod 12 and the rotating rod 11; one end of the locking rod 12 away from the rotating rod 11 is arranged in an arc shape; during operation, when the user needs to fix the stirrup on the top of the connecting seat 8, the user needs to first rotate the rotating rod 11 so that the rotating rod 11 rotates to a vertical state, and then the user inserts the bottom of the stirrup into the gap between the locking rod 12 and the receiving seat 9. At this time, the first spring 13 will be stretched, so that the stirrup can be smoothly inserted into the gap between the locking rod 12 and the receiving seat 9 and enter the slot 40 on the top surface of the receiving seat 9. Subsequently, the stretched first spring 13 resumes, buckling the locking rod 12 on the surface of the stirrup, thereby completing the fixation of the stirrup. When the pressing plate 4 fixes the stirrup, the user only needs to rotate the rotating rod 11 so that the locking rod 12 at its end no longer presses the stirrup, and then the lifting component drives the receiving seat 9 to descend, so that the stirrup disengages from the clamping groove 10. At this time, the stirrup can be welded to the main reinforcement. Through the cooperation of the rotating rod 11, the locking rod 12, the first spring 13 and the clamping groove 10, the fixation and unlocking of the stirrup can be quickly completed, thereby reducing the operation difficulty of the user.

[0035] As Figures 3 to 5As shown, on both sides of the top of the moving box 6, there are sliding connections with push rods 14, and the push rods 14 can come into contact with the vertical parts of the locking rods 12; on the top surface of the connecting seat 8, a magnet block 15 and a magnet plate 16 are respectively fixed on both sides of the rotating rod 11; the magnet plate 16 is located on the side of the rotating rod 11 close to the driving seat 2, while the magnet block 15 is located on the side of the rotating rod 11 far from the driving seat 2; the rotating rod 11 is made of magnetizable metal; during operation, when the user needs to quickly release the fixing of the locking rod 12 on the stirrup, the user can activate the push rod 14 to move the push rod 14 away from the driving seat 2. During the movement of the push rod 14, the push rod 14 will squeeze the locking rod 12, thereby driving the locking rod 12 and the rotating rod 11 to rotate away from the driving seat 2, so that the locking rod 12 is disengaged from the stirrup to release the fixing of the stirrup. When the rotating rod 11 approaches the magnet block 15 during rotation, the rotating rod 11 will be adsorbed by the magnet block 15 and the rotating rod 11 will be in a horizontal state, thus preventing the locking rod 12 from blocking the continuous movement of the push rod 14 away from the driving seat 2. When the push rod 14 moves to the end of the moving box 6 far from the driving seat 2, the locking rods 12 on the top of each connecting seat 8 are all released from locking the stirrup. Subsequently, the push rod 14 returns to the end of the moving box 6 close to the driving seat 2. When the user needs to fix the stirrup and thus requires the rotating rod 11 to be in a vertical state, after the user rotates the rotating rod 11 to the vertical state, the surface of the rotating rod 11 will fit on the surface of the magnet plate 16 and thus be adsorbed by the magnet plate 16, making the rotating rod 11 always remain in a vertical state, thus facilitating the user to fix the stirrup. Through the settings of the push rod 14, the magnet block 15, the magnet plate 16 and the push rod 14, the user can quickly release the fixing of multiple locking rods 12 on the stirrup, and at the same time, it is also convenient for the user to install and fix the stirrup.

[0036] As Figures 4 to 5As shown, gears 17 are fixedly connected to the surfaces of the rotating rods 11 that are not adjacent to the driving seat 2; the gears 17 are located at the rotational connection of the rotating rods 11 and the connecting seat 8; a chute 18 is formed inside the connecting seat 8; a toothed plate 19 is slidably connected in the chute 18; the toothed plate 19 is meshed with the gear 17; during operation, when it is necessary to install the stirrup on the top of the connecting seat 8 and the rotating rods 11 are all in a horizontal state, at this time, a part of the toothed plate 19 will be located outside the chute 18. The user needs to control the scissor-type telescopic frame 7 to contract, so as to drive each connecting seat 8 to move towards the connecting seat 8 adjacent to the driving seat 2. During this process, the toothed plate 19 will be squeezed by the adjacent connecting seat 8, and the toothed plate 19 will be pressed into the chute 18. When the toothed plate 19 moves towards the inside of the chute 18, the toothed plate 19 will drive the gear 17 to rotate, and the gear 17 will drive the rotating rod 11 to rotate, so that the rotating rod 11 rotates from the horizontal state to the vertical state, while the rotating rod 11 adjacent to the driving seat 2 needs to be manually rotated to the vertical state by the user. Thus, the user can reduce a lot of repetitive labor, and further reduce the operation difficulty of the user.

[0037] As Figure 1 , Figure 6 and Figure 7As shown, the welding assembly includes a welding table 20; an installation groove 21 is formed on one side of the welding table 20 close to the base 1; a push plate 22 is slidably connected in the installation groove 21, and the push plate 22 is driven by a power assembly; a plurality of uniformly arranged receiving rods 23 are slidably connected to one side of the push plate 22 close to the base 1, and the receiving rods 23 are arranged in an L shape; a limiting block 24 is arranged between adjacent receiving rods 23; the limiting block 24 is slidably connected to the push plate 22, and the width of the limiting block 24 is the same as that of the connecting seat 8; a cylinder 25 is slidably connected to the top surface of the welding table 20; a welding torch 26 is installed at the telescopic end of the cylinder 25; the cylinder 25 is fixedly connected to the receiving rod 23; during operation, when the stirrup is fixed on the top of the connecting seat 8, the user needs to push all the receiving rods 23 on the surface of the push plate 22 towards the driving seat 2. However, due to the blocking of the limiting block 24, the distance between each receiving rod 23 is the same as the distance between the top receiving seats 9 when they are attached to each connecting seat 8. Then, the power assembly pushes the push plate 22 towards the stirrup at the connecting seat 8, and makes the receiving rods 23 on the surface of the push plate 22 lean against one side of the stirrup. At this time, when the scissor-type telescopic frame 7 drives the stirrup to move, the stirrup will also push the receiving rod 23 to move. Since the receiving rod 23 is fixedly connected to the cylinder 25, the cylinder 25 will also move along with the receiving rod 23, thereby driving the welding torch 26 to move along. Subsequently, the main reinforcement is placed at the receiving rod 23 and is attached to the stirrup. At this time, the receiving rod 23 is exactly located at the contact point between the stirrup and the main reinforcement. Thus, the welding torch 26 can complete the welding between the stirrup and the main reinforcement. Since the welding torch 26 moves along with the receiving rod 23, there is no need for the user to manually adjust the position of the welding torch 26, thereby reducing the operation difficulty of the user and improving the usability of the embodiment of the present invention.

[0038] As Figures 6 to 7As shown, the power assembly includes a plurality of evenly arranged hydraulic cylinders 27, and the hydraulic cylinders 27 are fixedly connected inside the installation groove 21; the telescopic end of the hydraulic cylinder 27 is fixedly connected with a pressing plate 28; a second spring 29 is fixedly connected between the pressing plate 28 and the pushing plate 22; the bottom surface of the air cylinder 25 is fixedly connected with a sliding plate 30, and the sliding plate 30 is slidably connected with the welding table 20. The sliding plate 30 extends into the installation groove 21 and is located between the pressing plate 28 and the pushing plate 22. During operation, when the user needs to push the receiving rod 23 to one side of the stirrup, the hydraulic cylinder 27 will first push the pressing plate 28 towards the rotating pipe 3, and the pressing plate 28 will then push the pushing plate 22 and the receiving rod 23 thereon towards the rotating pipe 3 through the spring until the pushing plate 22 fits against the inner wall of the installation groove 21. At this time, the pushing plate 22 can no longer move. Then, the hydraulic cylinder 27 continues to push the pressing plate 28 and compresses the spring between the pressing plate 28 and the pushing plate 22, so that the pressing plate 28 and the pushing plate 22 can clamp the sliding plate 30 on the surface of the air cylinder 25, thereby fixing the air cylinder 25 and avoiding the shaking of the air cylinder 25 during operation, which may cause the welding torch 26 to be misaligned and prevent the welding torch 26 from correctly welding the main reinforcement and the stirrup together.

[0039] As Figure 7 shown, a moving seat 31 is slidably connected to the top surface of the welding table 20; a pushing rod 32 is fixedly connected to one side of the moving seat 31 close to the air cylinder 25; the pushing plate 22 can be in contact with the air cylinder 25. During operation, when the user needs to push each receiving rod 23 and the air cylinder 25 towards the driving seat 2, the user can control the moving seat 31 to move towards the driving seat 2. During the movement, the moving seat 31 will drive the pushing rod 32 to move towards the driving seat 2, and the pushing rod 32 can push the air cylinder 25 to move, so that each air cylinder 25 is concentrated at one end of the welding table 20 close to the driving seat 2, thus avoiding the user from manually moving each air cylinder 25, reducing the workload of the user, and improving the work efficiency.

[0040] As Figure 4 、 Figure 8 and Figure 9As shown in the figure, the lifting system includes a pallet 33; the pallet 33 is arranged on the bottom surface of the receiving seat 9, and the pallet 33 is driven by a hydraulic system; on the top surface of the connecting seat 8, connecting pipes 34 are fixedly connected to both sides of the receiving seat 9, and the connecting pipes 34 are symmetrical about the receiving seat 9; the connecting pipes 34 are arranged in a U shape, and one end of the connecting pipe 34 away from the receiving seat 9 is higher than the end close to the receiving seat 9; both ends of the connecting pipe 34 are slidably connected with pressure rods 35, and the inside of the connecting pipe 34 is filled with hydraulic oil; on one side of the receiving seat 9, a straight plate 36 is fixedly connected at the corresponding position of the pressure rod 35; during operation, when the stirrups and the main reinforcement are welded into a steel bar framework, the pallet 33 drives the receiving seat 9 to rise and supports the bottom of the steel bar framework. Subsequently, the rotating arm 5 on the surface of the rotating pipe 3 rotates, causing the abutting plate 4 to retract towards the rotating pipe 3. At this time, the steel bar cage will be placed on the receiving seat 9. Then, the moving box 6 moves in a direction away from the driving seat 2, and the steel bar framework can be completely removed from the rotating pipe 3. Then, the pallet 33 drives the receiving seat 9 to descend, so that the straight plate 36 on one side of the receiving seat 9 squeezes the pressure rod 35 on the side of the connecting pipe 34 close to the receiving seat 9. Since the inside of the connecting pipe 34 is filled with hydraulic oil, after the side close to the receiving seat 9 is squeezed and descends, the pressure rod 35 on the side away from the receiving seat 9 will rise, causing the pressure rod 35 to squeeze one side of the steel bar framework, and further causing the steel bar framework to slide off from one side of the receiving seat 9, thus facilitating the user to complete the blanking operation.

[0041] As Figures 8 to 9 shown in the figure, a column 37 is fixedly connected to the top surface of the pallet 33; a connection hole 38 is opened at the corresponding position of the bottom surface of the receiving seat 9 for the column 37; the column 37 is arranged in the connection hole 38, and the connection hole 38 is adapted to the column 37; a pair of insertion rods 39 are fixedly connected to the top surface of the pallet 33; the insertion rods 39 are located on both sides of the column 37 and are symmetrical about the column 37; at the corresponding position of the bottom surface of the connecting seat 8 for the insertion rods 39, a slot 40 is opened, and the slot 40 is adapted to the insertion rods 39; during operation, when the user needs to change the blanking direction of the steel bar framework, the user can lift the connecting seat 8 and rotate the receiving seat 9 by 180 degrees around the column 37, and then insert the column 37 into the connection hole 38 again. At this time, the two insertion rods 39 on the top surface of the pallet 33 will also be smoothly inserted into the slots 40 on the bottom surface of the receiving seat 9. Thus, the straight plate 36 on the surface of the receiving seat 9 will also rotate by 180 degrees, and further can squeeze the pressure rod 35 at the connecting pipe 34 on the other side of the receiving seat 9, thereby changing the direction in which the steel bar framework rolls off from the receiving seat 9, so as to adapt to different installation environments.

[0042] As Figures 1 to 10As shown, a support frame 41 is fixedly connected to the top surface of the moving box 6 and near one end of the rotating pipe 3; a groove 42 is formed in the surface of the support frame 41 at a position corresponding to the rotating pipe 3, and the groove 42 is adapted to the rotating pipe 3; a plurality of uniformly arranged support wheels 43 are rotatably connected to the inner wall of the groove 42; during operation, when the user moves the end of the moving box 6 to the driving seat 2, the support frame 41 at the end of the moving box 6 away from the driving seat 2 will move to the end of the rotating pipe 3 away from the driving seat 2, and the support wheels 43 at the groove 42 of the support frame 41 can contact the end of the rotating pipe 3 away from the driving seat 2, so as to provide support for the rotating pipe 3, avoid deformation of the rotating pipe 3 due to only one end being supported for a long time, and at the same time, the rollers at the groove 42 can also reduce the friction force when the rotating pipe 3 rotates, thereby reducing the wear of the rotating pipe 3.

[0043] During operation, in order to conveniently weld the stirrups and the main bars together evenly, the embodiment of the present invention can be used. First, the user needs to drive the moving box 6 to slide on the base 1 so that it is no longer located at the bottom of the rotating pipe 3. Then, the user installs the required stirrups on the top surface of the connecting seat 8 through the fixing component. After that, the user drives the moving box 6 to move back to the bottom of the rotating pipe 3. At this time, the stirrups on the connecting seat 8 will just pass through the rotating pipe 3 and the pressing plate 4 on its surface. Then, the user drives the scissor-type telescopic frame 7 to gradually extend through the lead screw. At this time, the scissor-type telescopic frame 7 will drive the connecting seat 8 connected thereto to move, and the distance between the stirrups will be evenly increased. Until the distance between the stirrups at the head and tail ends is the same as the length of the main bar, the user drives the rotating arm 5 to rotate through the hydraulic system, so that the rotating arm 5 drives the pressing plate 4 to press the inner side of the stirrup, thereby fixing the stirrup. Then, the welding component will place the main bar against the outer side of the stirrup, and then weld each stirrup and the main bar together through the welding component. After that, the driving seat 2 drives the rotating pipe 3 to rotate, and the rotating pipe 3 drives the stirrups and the welded main bars to rotate, so as to align the non-welded area of the stirrup with the welding component. Then, the welding component repeats the previous welding operation until the main bar is evenly welded on the surface of the stirrup, thereby completing the welding of the steel bar cage. By driving the connecting seat 8 and the stirrups thereon to move through the scissor-type telescopic frame 7, the distance between the stirrups is the same, so that the stirrups can be evenly welded on the surface of the main bar, thus eliminating the need for the user to calculate according to the length of the main bar, enabling the user to weld the stirrups and the main bars together more quickly, and thereby improving the production efficiency.

[0044] When the user needs to fix the stirrup on the top of the connecting seat 8, the user needs to first rotate the rotating rod 11 so that the rotating rod 11 rotates to the vertical state. Then the user inserts the bottom of the stirrup into the gap between the locking rod 12 and the receiving seat 9. At this time, the first spring 13 will be stretched, enabling the stirrup to be smoothly inserted between the locking rod 12 and the receiving seat 9 and into the slot 40 on the top surface of the receiving seat 9. Subsequently, the stretched first spring 13 resumes its shape, buckling the locking rod 12 on the surface of the stirrup, thereby completing the fixation of the stirrup. When the backing plate 4 fixes the stirrup, the user only needs to rotate the rotating rod 11 so that the locking rod 12 at its end no longer presses on the stirrup. Then the lifting assembly drives the receiving seat 9 to descend, causing the stirrup to disengage from the card slot 10. At this time, the stirrup can be welded to the main reinforcement. Through the cooperation of the rotating rod 11, the locking rod 12, the first spring 13, and the card slot 10, the fixation and unlocking of the stirrup can be quickly completed, thus reducing the operation difficulty for the user.

[0045] When the user needs to quickly release the fixation of the locking rod 12 on the stirrup, the user can activate the push rod 14 to move the push rod 14 away from the drive seat 2 from the drive seat 2. During the movement of the push rod 14, the push rod 14 will squeeze the locking rod 12, thereby driving the locking rod 12 and the rotating rod 11 to rotate away from the drive seat 2, and then causing the locking rod 12 to disengage from the stirrup to release the fixation of the stirrup. When the rotating rod 11 approaches the magnet block 15 during rotation, the rotating rod 11 will be adsorbed by the magnet block 15 and make the rotating rod 11 in a horizontal state, thus preventing the locking rod 12 from blocking the continuous movement of the push rod 14 away from the drive seat 2. When the push rod 14 moves to the end of the moving box 6 away from the drive seat 2, the locking rods 12 on the tops of all the connecting seats 8 release the locking of the stirrup. Subsequently, the push rod 14 returns to the end of the moving box 6 close to the drive seat 2. When the user needs to fix the stirrup and thus requires the rotating rod 11 to be in the vertical state, after the user rotates the rotating rod 11 to the vertical state again, the surface of the rotating rod 11 will fit on the surface of the magnet plate 16 and thus be adsorbed by the magnet plate 16, causing the rotating rod 11 to always maintain the vertical state, thus facilitating the user to fix the stirrup. Through the settings of the push rod 14, the magnet block 15, the magnet plate 16, and the push rod 14, the user can quickly release the fixation of multiple locking rods 12 on the stirrup, and at the same time, it is also convenient for the user to install and fix the stirrup.

[0046] When it is necessary to install the stirrup on the top of the connecting seat 8 and the rotating rods 11 are all in a horizontal state, at this time, a part of the toothed plate 19 will be located outside the sliding groove 18. The user needs to control the scissor-type telescopic frame 7 to contract, so as to drive each connecting seat 8 to move towards the connecting seat 8 adjacent to the driving seat 2. During this process, the toothed plate 19 will be squeezed by the adjacent connecting seat 8, and the toothed plate 19 will be pressed into the sliding groove 18. When the toothed plate 19 moves towards the inside of the sliding groove 18, the toothed plate 19 will drive the gear 17 to rotate, and the gear 17 will drive the rotating rod 11 to rotate, so that the rotating rod 11 rotates from the horizontal state to the vertical state, and the rotating rod 11 adjacent to the driving seat 2 needs to be manually rotated to the vertical state by the user. Thus, the user can reduce a lot of repetitive labor, and further reduce the operation difficulty of the user.

[0047] After the stirrup is fixed on the top of the connecting seat 8, the user needs to push the receiving rods 23 on the surface of the push plate 22 towards the driving seat 2. However, due to the block of the limit block 24, the distance between the receiving rods 23 is the same as the distance between the top receiving seats 9 when they are in contact with each connecting seat 8. Then the power assembly pushes the push plate 22 towards the stirrup at the connecting seat 8, and makes the receiving rods 23 on the surface of the push plate 22 lean against one side of the stirrup. At this time, when the scissor-type telescopic frame 7 drives the stirrup to move, the stirrup will also push the receiving rod 23 to move. Since the receiving rod 23 is fixedly connected to the cylinder 25, the cylinder 25 will also move along with the receiving rod 23, and then drive the welding torch 26 to move along with it. Subsequently, the main reinforcement is placed at the receiving rod 23 and is in contact with the stirrup. At this time, the receiving rod 23 is exactly located at the contact point between the stirrup and the main reinforcement. Thus, the welding torch 26 can complete the welding between the stirrup and the main reinforcement. Since the welding torch 26 moves along with the receiving rod 23, the user does not need to manually adjust the position of the welding torch 26, thereby reducing the operation difficulty of the user and improving the usability of the embodiment of the present invention.

[0048] When the user needs to push the receiving rod 23 to one side of the stirrup, the hydraulic cylinder 27 will first push the pressing plate 28 towards the direction of the rotating tube 3, and the pressing plate 28 will push the push plate 22 and the receiving rod 23 thereon towards the direction of the rotating tube 3 through the spring until the push plate 22 fits against the inner wall of the installation groove 21. At this time, the push plate 22 can no longer move. At this time, the hydraulic cylinder 27 continues to push the pressing plate 28 and compresses the spring between the pressing plate 28 and the push plate 22, so that the pressing plate 28 and the push plate 22 can clamp the sliding plate 30 on the surface of the cylinder 25, thereby fixing the cylinder 25, so as to avoid the shaking of the cylinder 25 during operation, resulting in the misalignment of the welding torch 26 and the inability to correctly weld the main reinforcement and the stirrup together by the welding torch 26.

[0049] When the user needs to push each receiving rod 23 and the air cylinder 25 towards the driving seat 2, the user can control the moving seat 31 to move towards the driving seat 2. During the movement, the moving seat 31 will drive the pushing rod 32 to move towards the driving seat 2, and the pushing rod 32 can push the air cylinder 25 to move, so that each air cylinder 25 is concentrated at one end of the welding table 20 close to the driving seat 2, thus avoiding the user manually moving each air cylinder 25, reducing the workload of the user, and improving work efficiency.

[0050] After the stirrup and the main reinforcement are welded into a steel bar cage, the support plate 33 drives the receiving seat 9 to rise and supports the bottom of the steel bar cage. Subsequently, the rotating arm 5 on the surface of the rotating pipe 3 rotates, causing the pressing plate 4 to move towards the rotating pipe 3. At this time, the steel bar cage will be placed on the receiving seat 9. Then, the moving box 6 moves in the direction away from the driving seat 2, and the steel bar cage can be completely removed from the rotating pipe 3. Then, the support plate 33 drives the receiving seat 9 to descend, so that the straight plate 36 on one side of the receiving seat 9 presses the pressure rod 35 on the side of the connecting pipe 34 close to the receiving seat 9. Since the inside of the connecting pipe 34 is filled with hydraulic oil, after the side close to the receiving seat 9 is squeezed and descends, the pressure rod 35 on the side away from the receiving seat 9 will rise, causing the pressure rod 35 to squeeze one side of the steel bar cage, so that the steel bar cage slides off from one side of the receiving seat 9, thus facilitating the user to complete the blanking operation.

[0051] When the user needs to change the blanking direction of the steel bar cage, the user can lift the connecting seat 8 and rotate the receiving seat 9 180 degrees around the column 37, and then insert the column 37 into the connecting hole 38 again. At this time, the two inserting rods 39 on the top surface of the support plate 33 will also be smoothly inserted into the slot 40 on the bottom surface of the receiving seat 9. Thus, the straight plate 36 on the surface of the receiving seat 9 will also rotate 180 degrees accordingly, and then can squeeze the pressure rod 35 at the connecting pipe 34 on the other side of the receiving seat 9, thereby changing the direction in which the steel bar cage rolls off from the receiving seat 9, so as to adapt to different installation environments.

[0052] When the user moves the end of the moving box 6 to the driving seat 2, the support frame 41 at the end of the moving box 6 away from the driving seat 2 will move to the end of the rotating pipe 3 away from the driving seat 2, and the support wheel 43 at the groove 42 of the support frame 41 can contact the end of the rotating pipe 3 away from the driving seat 2, thereby providing support for the rotating pipe 3, avoiding deformation of the rotating pipe 3 due to being supported only at one end for a long time. At the same time, the roller at the groove 42 can also reduce the friction force when the rotating pipe 3 rotates, thereby reducing the wear of the rotating pipe 3.
