[0017] The utility model is described in detail below in conjunction with the accompanying drawings.
[0018] The structure of the automatic weighing and metering device for pipes provided in this embodiment is as follows: Figure 1-2 As shown, the device includes a frame, a lifting mechanism and a weighing mechanism.
[0019] The frame is a gantry frame, and the frame includes two columns 1 and a crossbeam 2. Foot pads 3 are welded to the lower ends of the two columns 1, and both sides of the foot pads 3 are fixed to the ground by expansion bolts, and the upper ends of the two columns 1 are connected to the two ends of the crossbeam 2 respectively.
[0020] The lifting mechanism includes a cylinder 4, a lifting support plate 5 and a guide rod 6, and there are two guide rods 6. The lifting support plate 5 is in a strip shape, and the lifting support plate 5 is arranged horizontally, and the lifting support plate 5 is located directly above the crossbeam 2. The outer shell of the cylinder 4 is located below the crossbeam, and the top of the outer shell of the cylinder 4 is fixed to the crossbeam 2 by screws. A through hole 7 is provided in the center of the crossbeam 2, and the diameter of the through hole 7 is larger than the diameter of the piston rod of the cylinder 4, and the piston rod of the cylinder 4 movably passes through the crossbeam 2 through the through hole 7.
[0021] The two guide rods 6 are symmetrically arranged on both sides of the piston rod of the cylinder 4, and the two guide rods 6 are respectively located on the inner sides of the two columns 1. The two guide rods 6 respectively penetrate the two sides of the crossbeam 2, and the two guide rods 6 are respectively connected to the crossbeam 2 through linear bearings 8, and the upper ends of the two guide rods 6 are respectively connected to the two ends of the lifting support plate 5. The guide rods 6 play a role of guidance and balance, preventing the weighing sensor 9 from tilting during the rising process and the weighing process, which affects the accuracy and precision of the weighing.
[0022] The weighing mechanism includes a weighing sensor 9 and a support bracket for supporting the tube. A first cushion block 10 is provided on one side of the lifting support plate 5, one end of the weighing sensor 9 is located on the first cushion block 10, and the weighing sensor 9 and the first cushion block are fixed to the lifting support plate 5 by fastening bolts.
[0023] The support frame is in an I-shape, and includes a connecting plate 12 and two supporting rods 13. The connecting plate 12 is in a strip shape. A second cushion block 11 is provided on the other end of the weighing sensor 9. One side of the connecting plate 12 is located on the second cushion block 11. The connecting plate 12 and the second cushion block 11 are fixed to the weighing sensor 9 by fastening bolts. The supporting rod 13 is in a U-shape. The two supporting rods 13 are respectively located above the two ends of the connecting plate 12, and the middle parts of the two supporting plates 13 are respectively fixedly connected to the two ends of the connecting plate 12.
[0024] Before the pipes are packaged, the bundles of pipes are placed on the cantilever shelf. When the pipes on the cantilever shelf need to be weighed, the cylinder 4 is opened through the manual reversing valve, and the piston rod of the cylinder 4 drives the lifting support plate 5 to rise, and the lifting support plate 5 drives the weighing sensor 9 to rise, and the weighing sensor 9 drives the supporting frame to rise. When the supporting frame rises to a certain height, the supporting frame contacts the pipes. When the supporting frame continues to rise, the pipes on the cantilever shelf are transferred to the supporting frame. At this time, the weighing sensor weighs the pipes on the supporting frame. When the weighing sensor 9 transmits the weight data of the pipes to the display screen, after the value on the display screen stabilizes, the operator reads the value displayed on the display screen, which is the weight of the bundled pipes to be weighed. After the weighing is completed, the reversing valve is manually operated, and the piston rod of the cylinder 4 drives the lifting support plate 5, the weighing sensor 9 and the support frame to descend. When the support frame descends to a certain height, the pipes on the support frame are transferred to the arm-type shelf. Then the piston rod of the cylinder drives the lifting support plate 5, the weighing sensor 9 and the support frame to continue to descend until the lifting support plate 5, the weighing sensor 9 and the support frame are reset.
[0025] If the bundle of pipes to be weighed is long, multiple measuring devices can be used for weighing. The multiple measuring devices are evenly arranged along the length of the pipes, and the above method is used to operate. The average value of the weighing values of the multiple measuring devices is taken, which is the weight of the bundle of pipes to be weighed.
