[0002] The current welded pipe production and manufacturing workshop has problems such as boxing, weighing and shipping, which are complicated processes, require large manpower input and occupy a large area. In addition, the average weight of the wooden boxes is more than 1 ton, and double-beam lifting equipment is used for lifting.

[0003] The existing packing and shipping process first uses a crane to lift the empty wooden crate to a floor scale for weighing, determining the net weight of the crate, T1. The empty crate is then lifted to a concrete floor, where personnel manually load the welded pipes into the crate. Once loaded, the crane then lifts the fully loaded crate onto a floor scale for weighing, determining the gross weight, T2. The crate is then lifted to a warehouse or onto a shipping truck (net weight of the welded pipe = gross weight of the welded pipe, T2 - net weight of the crate, T1).

[0004] In the prior art, the empty wooden box is first lifted by a crane for empty weighing, and the weight of the wooden box T1 is recorded; the wooden box is then lowered by the crane and the welded pipes are packed into the box; the finished wooden box is then lifted back by the crane onto the load-bearing device for full box weighing, and the weight of the full box T2 is recorded, and the net weight of the welded pipe T = T2 - T1 is obtained; finally, the crane is used to lift the box to the warehouse or for shipment. However, in the entire packing and weighing process, the crane is used four times, and the frequent lifting times result in significant equipment wear and tear, posing a certain risk of product damage and personnel safety hazards.

A system for packing and weighing welded pipes includes: a limiting device 1;

[0033] A wooden box 2, which is arranged on the top of the limiting device 1;

[0034] A hydraulic drive device 3 is provided at the bottom of the wooden box 2 and includes a hydraulic oil pipe 31. A hydraulic drive system 32 is fixedly mounted on one end of the hydraulic oil pipe 31, and a hydraulic cylinder 33 is fixedly mounted on the other end of the hydraulic oil pipe 31. A weight sensor 34 is fixedly connected to the top end of the output shaft of the hydraulic cylinder 33.

[0035] The weight display device 4 is fixedly mounted on the hydraulic drive device 3 .

[0036] The hydraulic drive device 3 is connected to the two hydraulic cylinders 33 in two ways through the hydraulic oil pipe 31 to ensure the consistency of the actions of the two hydraulic cylinders 33.

[0037] A weight sensor 34 is installed at the extended end of the hydraulic cylinder 33 for measuring weight. The weight data measured by the two weight sensors 34 are transmitted to the internal program of the weight display device 4 for calculation and statistics.

[0038] The control system of the electromagnetic induction valve and other components of the hydraulic drive device 3 is connected to the weight display device 4 and is controlled by the weight display device 4 .

[0039] The limiting device 1 includes a mounting seat 101, a rotating cylinder 102 is fixedly installed in the middle of the mounting seat 101, the outer surface of the output shaft of the rotating cylinder 102 is fixedly connected to the rotating shaft 103, a lifting plate 105 is fixedly installed on the top of the rotating shaft 103, and a bearing 104 is fixedly installed on the outer surface of the rotating shaft 103.

[0040] The output shaft of the rotating cylinder 102 controls the rotation of the rotating shaft 103 through an external power supply. The rotating shaft 103 rotates in the mounting seat 101 through the bearing 104. When the rotating shaft 103 rotates, it drives the lifting plate 105 to rotate, and the wooden box 2 is lifted by the lifting plate 105. The four limit devices 1 are respectively arranged around the bottom of the wooden box 2, and the four lifting plates 105 support the wooden box 2 from the bottom.

[0041] A rotating cylinder 102 is installed at the bottom of the limiting device 1 to drive the rotating shaft 103 to rotate. The rotating shaft 103 is supported by a bearing 104 to drive the lifting plate 105 to move to a specified position.

[0042] The rotation angle of the rotary cylinder 102 is adjusted by the adjustment knob, and the control valve sensor is connected to the weight display device 4 and is controlled by the weight display device 4.

[0043] A support column 5 is provided on one side of the limiting device 1 , and a placement platform 6 is fixedly installed on the top of the support column 5 .

[0044] The top of the placement platform 6 can be used to place the welded pipe.

[0045] There are two hydraulic cylinders 33 , and the weight sensor 34 is provided at the top end of the output shaft of each hydraulic cylinder 33 .

[0046] The weight display device 4 is connected to the hydraulic drive system 32 and the limit device 1 control sensor, and controls the limit and jacking and other action instructions through PLC. It also has the action program adjustment and programming functions, a handheld remote control, and a wireless data docking function with the weight display device 4, as well as a control function, which is convenient for workers to operate.

[0047] The weight sensors 34 are used for weight measurement. The weight measurement data of the two weight sensors 34 are transmitted to the internal program of the weight display device 4 for calculation and statistics.

[0048] During the packing operation, the hydraulic drive device 3 is in position 0, the limit device 1 is in position 1, the wooden box 2 is in the top packing position, and the weight sensor 34 is suspended. Because the weight sensor is always in a load-bearing state and is easily damaged, the service life of the weight sensor 34 is extended.

[0049] The rotating cylinder 102 is installed at the bottom of the limiting device 1 to drive the rotating shaft 103 to rotate. The rotating shaft 103 is supported by the bearing 104 to drive the lifting plate 105 to move to the specified position. The rotation angle of the rotating cylinder 102 is adjusted by the adjustment knob, and the control valve sensor is connected to the weight display device 4, which can be controlled by the weight display device 4.

[0050] After the wooden box 2 is lifted to the weight sensor 34 for empty box weighing, it reaches the packing position through the hydraulic drive device 3. Then the limit device 1 limits the position, and the hydraulic drive device 3 returns to its original position. The worker starts packing. After the packing work is completed, the hydraulic drive device 3 lifts the wooden box 2, and the limit device 1 returns to its original position. The weight sensor 34 transmits the total weight of the wooden box 2 to the weight display device 4 for recording. The wooden box 2 can then be lifted away, and the weighing and packing process is completed.

[0051] The working principle of the welded pipe packaging and weighing integrated system provided by the present invention is as follows:

[0052] During operation, the empty wooden box 2 is first lifted to the top of the weight sensor 34 by a lifting device, as shown in FIG. Figure 4 、 5 As shown, the limit device 1 and the hydraulic cylinder 33 are both in position 0, and the weight sensor 34 automatically records the empty weight T1 of the wooden box 2; the hydraulic cylinder 33 is controlled by an external power supply to move to position 1, the limit device 1 moves to position 1, and the hydraulic cylinder 33 moves back to position 0, the wooden box 2 is supported by the limit device 1, and the workers carry out the packing work.

[0053] After the box is packed, the hydraulic cylinder 33 is controlled by an external power supply to move to position 1, and the weight sensor 34 automatically records the weight T2 of the wooden box 2 and automatically calculates the net weight of the welded pipe T = T1 - T2. The hydraulic cylinder 33 is controlled by an external power supply to move to position 0, and the box packing and weighing actions are completed. Finally, the lifting equipment is used to lift the box to the warehouse or for shipment, and the lifting plate 105 of the limit device 1 returns to position 0.
