[0030] Reference Figure 2 The bidirectional telescopic assembly 23 includes a second connecting end and a second moving end, the second connecting end is connected to the crossbeam 22, and the second moving end is connected to the grabbing module 3. The second moving end can move laterally along the length direction of the bidirectional telescopic assembly 23, and further drive the grabbing module 3 to move laterally.

[0031] Reference Figures 2-3 The longitudinal movement component 21 is vertically arranged to the cross beam 22 , and the cross beam 22 is vertically arranged to the bidirectional telescopic component 23 .

[0032] Reference Figure 4The crossbeam 22 adopts a single support arm structure with a fixed length (for example, a frame structure formed by splicing a plurality of metal pipes by bolts or welding), and the crossbeam 22 includes a first transverse fixed end and a second transverse fixed end. The end of the crossbeam 22 close to the longitudinal movement assembly 21 is the first transverse fixed end, which is connected to the first moving end of the longitudinal movement assembly 21 (for example, fixedly connected by bolts); the end of the crossbeam 22 close to the bidirectional telescopic assembly 23 is the second transverse fixed end, which is connected to the second connecting end of the bidirectional telescopic assembly 23 (for example, fixedly connected by bolts).

[0033] Reference Figure 5 The crossbeam 22 adopts a combined support arm structure with variable length. The combined support arm includes an inner support arm 221 and an outer support arm 222, which are sleeved with each other. A guide rail and a rolling bearing are provided between the inner support arm 221 and the outer support arm 222 (for example, a rolling bearing is installed on the outer surface of the inner support arm 221 through bolts, and a guide rail is installed on the inner surface of the outer support arm 222 through bolts; or a guide rail is installed on the outer surface of the inner support arm 221 through bolts, and a rolling bearing is installed on the inner surface of the outer support arm 222 through bolts), and the rolling bearing is connected to the guide rail in a rolling manner. The combined support arm is driven by a linear drive device (for example, a cylinder or an oil cylinder). One end of the linear drive device is hinged to the inner support arm 221, and the other end of the linear drive device is hinged to the outer support arm 222. When the linear drive device is extended, the combined support arm is driven to extend, and when the linear drive device is shortened, the combined support arm is driven to shorten. During transportation, the linear drive device is shortened to make the sleeve length of the outer support arm 222 and the inner support arm 221 as long as possible, and further make the length of the crossbeam 22 as short as possible, thereby reducing the space occupied by the crossbeam 22 and improving the convenience and safety of transportation.

When there are two bidirectional telescopic components 23, the two bidirectional telescopic components 23 are respectively arranged at two ends of the lower surface of the outer support arm 222. When there are more than three bidirectional telescopic components 23, the bidirectional telescopic components 23 are arranged in a linear array with equal spacing on the lower surface of the outer support arm 222.

[0035] Reference Figure 2 and3 , the longitudinal movement component 21 is a screw structure. The screw structure includes a screw, a screw support, a screw nut, a load-bearing guide rail and a load-bearing guide sleeve. The screw support is fixedly installed on the side wall of the support module 1 by bolts; there are two screw supports, and the two screw supports are respectively sleeved and rotatably connected with the two ends of the screw (for example, connected by bearings); the screw is arranged longitudinally; the screw nut is provided with a screw hole, and the screw hole is threadedly matched with the external thread of the screw; the end of the screw is connected to the screw motor through a transmission gear set, and the screw motor is fixedly connected to the support module 1 by bolts. The screw motor can drive the screw to rotate, and further drive the screw nut to move longitudinally. The screw nut is fixedly connected to the crossbeam 22 by bolts, and the crossbeam 22 is driven to move synchronously longitudinally when the screw nut moves longitudinally. The screw nut is the first moving end, and the screw is the first connecting end. A load-bearing guide rail is respectively provided on the left and right sides of the screw, and the load-bearing guide rail is arranged parallel to the screw, and the load-bearing guide rail is fixedly connected to the support module 1 by bolts. The crossbeam 22 is fixedly connected to at least two bearing guide sleeves by bolts, and the two bearing guide sleeves are respectively slidably connected to two bearing guide rails. The bearing guide sleeve has a C-shaped cross section, and the bearing guide rail has an I-shaped cross section; the bearing guide sleeve is buckled on the surface of the bearing guide rail to prevent the bearing guide sleeve and the bearing guide rail from being separated.

[0036] Reference Figure 6 The bidirectional telescopic assembly 23 is a bidirectional telescopic arm. The bidirectional telescopic arm includes more than two sliding plates that are sleeved in sequence, and the adjacent sliding plates are driven by a gear rack structure.

[0037] Reference Figures 6-7For example, the bidirectional telescopic arm includes three sliding plates which are sleeved in sequence: a first sliding plate with a π-shaped cross section, a second sliding plate with a U-shaped cross section, and a third sliding plate with a U-shaped cross section. The first sliding plate is fixedly connected to the bottom surface of the cross beam 22 by bolts. The first sliding plate is provided with a first guide protrusion in a strip shape (for example, connected by integral molding), and the second sliding plate is provided with a first guide groove (for example, connected by integral molding) which is slidably connected to the first clamping protrusion; the second sliding plate is provided with a second guide protrusion in a strip shape (for example, connected by integral molding), and the third sliding plate is provided with a second guide groove (for example, connected by integral molding) which is slidably connected to the second clamping protrusion.

Since the first sliding plate is fixedly connected to the crossbeam 22, it is specifically manifested as the movement of the second sliding plate and the second sliding plate.

[0038] Reference Figure 7 In the bidirectional telescopic assembly 23, except for the first sliding plate, all other sliding plates can move in both directions, so that the moving range of the grabbing module 3 is wider, and the stack of pipes 0 obtained by arranging the pipes has a larger width and a smaller height (under the premise that the total number of pipes 0 is inconvenient), so that the stack of pipes 0 has better stability and improves the safety of storage and transportation.

[0039] Reference Figure 2 The support module 1 includes a support column, a support frame, a support plate or a combination thereof (e.g., a combination structure of a support column and a support plate). An auxiliary support leg 11 (e.g., fixedly connected by bolts) is provided on the bottom side of the support module 1. The auxiliary support leg 11 is used to assist in bearing the load, so as to improve the stability of the support module 1. An extension plate (e.g., fixedly connected by bolts) is provided on the bottom side of the support module 1. The extension plate and the crossbeam 22 are located on the same side of the support module 1. The extension plate is arranged parallel to the crossbeam 22. When in use, the extension plate is fixedly connected to the cofferdam 4 (e.g., fixed by bolts) or crimped (e.g., the cofferdam 4 is crimped onto the upper surface of the extension plate), and the weight of the cofferdam 4 and the pipe 0 is used to improve the stability of the support module 1.

[0040] The grabbing module 3 is an electromagnetic suction cup, which is used to grab the iron-containing pipe fitting 0. It is a conventional existing technology in the industry and will not be described in detail.

[0041] Among them, the electromagnetic suction cup, the screw motor and the drive motor are respectively connected to the power system, and the linear drive device is connected to the pneumatic system or the hydraulic system to realize energy transmission.

[0042] The utility model has a simple structure, reliable functions and flexible operation. The utility model realizes flexible driving of the grabbing module 3 and the pipe fittings 0 through the moving assembly, the crossbeam 22 and the bidirectional telescopic assembly 23. The bidirectional telescopic assembly 23 capable of bidirectional movement enables the pipe fittings 0 stack obtained by arranging the pipes to have a larger width and a smaller height, thereby lowering the center of gravity of the stack so as to have better stability and improve the safety of storage and transportation.
