The weighing device 24 may be a pressure type, a strain type, or any other feasible weight sensing device.

Referring to fig. 1, in this embodiment, the two lifting assemblies are symmetrically arranged on the walking bracket 21, and the lifting plates 23 of the two lifting assemblies are rigidly connected through the connecting rod 25, so that the two lifting assemblies are trimmed to form a whole, when the lifter 22 works and lifts, the rigid connection of the connecting rod 25 enables the lifting actions of the two lifting assemblies to be synchronous, and the lifting asynchronism caused by the crawling and running errors due to the characteristics of the mechanisms among different hydraulic cylinders is eliminated, so that the lifting actions are synchronous and stable, and the errors are further reduced.

Meanwhile, the two lifting assemblies can be respectively positioned between the two supporting devices on the two sides along with the operation of the walking device. Whilst the support means comprise a base 11 and rollers 12 rotatably connected to the base 11, the steel duct transported from upstream of the production line falls sideways onto its nearest support means, and the rotation of the rollers 12 of the support means allows the steel duct to be moved with its rotation with low resistance above all the support means and thus to be taken into the weighing and subsequent transfer stacks.

In this embodiment, the traveling device further includes a second positioning device 28 located at the upper end of the traveling bracket 21 and juxtaposed on the downstream side of the lifting assembly 22 and pointing upward, the second positioning device 28 may be a laser or other type of sensor, and it is used for determining the position when the traveling device transfers the steel pipe stack, for example, after it moves from upstream to downstream to the lower side of the stacking device and is blocked by the steel pipe which has completed the stacking to generate an electric signal, the controller connected thereto controls the second servo motor to stop operating, thereby ensuring that the interval of each steel pipe is the interval from the position of the steel pipe on the lifting plate 23 to the position of the second positioning device 28, and making the stacking structure have the characteristic of order and stability, thereby facilitating the subsequent packing and transporting work.

In this embodiment, the stacking device includes two strip-shaped stacking supports 31 symmetrically disposed on the outside of the track, a first limiting portion 32 located at two ends of the stacking support 31 and used for preventing the steel pipe from falling, and an identification portion 33 disposed on the downstream side of the stacking support 31 and interacting with the second positioning device 28, where the identification portion 33 is located: when the second positioning device 28 moves to the lower part thereof to start the stopping action of the second servo motor, the lifting plate 23 is just positioned at the tail end of the stacking support 31, namely, the steel pipes on the lifting plate 23 cannot be sent out of the stacking support 31, so that the problem that the steel pipes cannot be stacked in an overtravel manner is prevented.

The online steel pipe weighing and stacking device has the following working process:

before the work starts, the second servomotor drives the traveling carriage 21 to move to a position where the lifting plate 23 corresponds to the supporting device in the vertical upstream and downstream direction (see the position in fig. 1), and at this time, the lifter 22 adjusts the height to a position where the top surface of the lifting plate 23 is lower than the top height of the roller 12. After that, the operation is started, the steel pipe is conveyed from the upstream of the production line to the supporting device, and the roller 12, the first servo motor 13 and the first positioning device 14 are simultaneously matched with the operation to carry out the centering action according to the flow described above. Thereafter, the elevator 22 is raised and the lifting plate 22 is raised above the top of the drum 12, i.e. the steel pipe is lifted from the support means, the weight of the steel pipe is then fully applied to the lifting assembly, and the weighing device 24 is operated and transmits the measured data to a microcomputer or display for recording, inspection and observation. The height at which the lifting plate 22 is finally lifted needs to be equal to or greater than the highest height of the stack holder 31 (first stopper portion 32). After weighing, the second servo motor starts to work and travel above the stacking support until the second positioning device 28 detects and stops the stacking support (referring to fig. 2, the position of the steel tube at the maximum position is realized by the interaction between the second positioning device 28 and the identification part 33). Thereafter, the lifter 22 descends and leaves the steel tube on the stacking support 31 for stacking action, and the lifter 22 finally descends the lifting plate 23 to the height reset below the roller 12 and the walking support 21 resets to the supporting device for waiting for the next weighing transfer.

As an optimization of the above-described work flow to further reduce the flow time and improve the efficiency, the return operation of the lifting plate 23 may be performed in synchronization with the return of the traveling carriage 21. Further, when the walking support 21 is reset to move, the supporting device can firstly receive the upstream steel pipe and start to center, so that the next round of weighing and transferring action can be performed immediately after the walking support is reset.

The above embodiments are only described for the preferred embodiments of the present invention, and are not intended to limit the concept and scope of the present invention, and the various modifications and improvements made by the ordinary person in the art without departing from the design concept of the present invention all fall into the protection scope of the present invention.
