the lower net sheet laying stage comprises the following steps:

step S10: the lower mesh 80 is supported and driven by the first conveying device 10 to move along the first direction until the lower mesh 80 is laid on the upper surface of the first conveying device 10. It should be understood that the first direction described in the present embodiment refers to the extending direction of the longitudinal rib (the left direction in fig. 2 a).

Specifically, as shown in fig. 2a and 2b, the lower mesh 80 is transferred by the conveyor belt 11 on the first conveyor 10 and the plurality of rollers 12 arranged at intervals in the first direction. The axial direction of the rollers 12 is perpendicular to the first direction, that is, the direction of the transverse ribs, the conveyor belt 11 is assembled on the plurality of rollers 12 around the self axial direction, and the rollers 12 rotate to drive the conveyor belt 11 to rotate along the self circumferential direction, so that the lower mesh 80 is driven to move.

The truss laying stage comprises:

step S20: the second conveying device 20 is arranged above the lower mesh sheet 80 of the first conveying device 10, and the longitudinal truss 100 in the lying state is supported and driven by the second conveying device 20 to move along the first direction, until the position of the longitudinal truss 100 along the first direction corresponds to the position of the lower mesh sheet 80 along the first direction, that is, the longitudinal truss 100 is located right above the longitudinal ribs of the lower mesh sheet 80 (or within a practical range of vertical positions).

Specifically, as shown in fig. 3a and 3c, the longitudinal girder 100 in the lying state is transferred by a plurality of rollers 12 arranged at intervals in the first direction on the second conveyor 20, wherein the rollers 12 rest on the upper side of the lower mesh 80 through the wings 21.

Step S30: as shown in fig. 3d, the longitudinal girder 100 is converted from the lying state to the standing state, and the second conveying device 20 is removed, so that the longitudinal girder 100 abuts against the lower mesh 80, that is, the longitudinal girder 100 abuts against the longitudinal ribs of the lower mesh 80. Specifically, the longitudinal girders 100 are manually converted from the lying state to the erected state, and the second transfer device 20 is manually removed.

Step S40: welding the longitudinal truss 100 and the lower mesh 80; specifically, the longitudinal girders 100 and the longitudinal ribs of the lower mesh 80 are welded and fixed manually.

Step S50: with continued reference to fig. 3d, the transverse girders 110 are arranged along a second direction perpendicular to the first direction (the transverse girders 110 are in an upright state at this time), and the transverse girders 110 are welded to the lower mesh 80, specifically, the transverse ribs of the transverse girders 110 and the lower mesh 80 are welded manually. The second direction in the present embodiment refers to a direction perpendicular to the longitudinal ribs, specifically, a direction along the extension direction of the transverse ribs (a direction perpendicular to the paper surface in fig. 3 d).

The upper mesh sheet 90 deployment phase includes:

step S60: as shown in fig. 4d, the third conveying device 30 is used to support and drive the upper mesh 90 to move along the first direction, until the upper mesh 90 is laid on the upper surface of the third conveying device 30, and the positions of the upper mesh 90 and the lower mesh 80 are corresponding, that is, the horizontal ribs of the upper mesh 90 correspond to the horizontal ribs of the lower mesh 80, the longitudinal ribs of the upper mesh 90 correspond to the longitudinal ribs of the lower mesh 80, at this time, the longitudinal trusses 100 correspond to the longitudinal ribs of the upper mesh 90, and the transverse trusses 110 correspond to the horizontal ribs of the upper mesh 90.

Specifically, the upper web 90 is transferred by a plurality of rollers 12 arranged on the third transfer device 30 at intervals in the first direction.

Further, referring to fig. 4b and 4c, the third conveying device 30 includes a supporting seat 31, at least one supporting column 32, and at least two rollers 12, in practical engineering, the width (length along the transverse bar) of the upper net 90 is generally much larger than the length of a single roller 12, at least two rollers 12 need to be connected to meet the width requirement of the upper net 90, and the two rollers 12 are connected by the supporting column. In an exemplary embodiment, continuing to refer to fig. 4c, two rollers 12 and a support post 32 are shown, with the end of the roller 12 not connected to the support post 32 connected to the bearing 31. Further, the support columns are temporarily fixed with the lower net piece 80, so that subsequent removal is facilitated.

Step S70: the third conveyor 30 is removed and the upper mesh 90 rests on the longitudinal girders 100 and the transverse girders 110.

Specifically, referring to fig. 4e, before removing the third conveying device 30, the method for manufacturing a reinforcement cage further includes driving the upper mesh 90 to be away from the third conveying device 30 along a vertical direction by using a telescopic device 60; and with reference to figure 4f of the drawings,

after the third conveying device 30 is removed, the method for manufacturing the reinforcement cage further includes driving the upper mesh 90 to vertically approach the longitudinal girders 100 and the transverse girders 110 by using the telescopic devices 60 until the upper mesh 90 abuts against the longitudinal girders 100 and the transverse girders 110. In one embodiment, the telescoping device 60 is a hydraulic cylinder or an air cylinder.

Further, the vertical position of the telescoping device 60 is configured to be close to the transverse rib of the upper mesh 90, so that the telescoping device 60 abuts against the transverse rib of the upper mesh 90, and supports the upper mesh 90 away from the third conveying device 30.

Step S80: referring to fig. 5, the longitudinal truss 100 is welded to the upper mesh 90, and the transverse truss 110 is welded to the upper mesh 90, specifically, longitudinal ribs of the longitudinal truss 100 and the upper mesh 90, and transverse ribs of the transverse truss 110 and the upper mesh 90 are respectively welded by a manual method, so as to form a reinforcement cage.

Preferably, the upper surfaces of the plurality of rollers 12 are arranged to be flush with each other so that the upper mesh sheet 90, the lower mesh sheet 80, and the longitudinal girder 100 are smoothly transferred.

It should be noted that, the structures of the lower net plate 80, the upper net plate 90, the longitudinal truss 100 and the transverse truss 110 described in this embodiment are shown in fig. 1c to fig. 1h in the background art sequentially. Specifically, referring to fig. 1c and 1d, the lower mesh 80, i.e., the transverse ribs, are below the longitudinal ribs; referring to fig. 1e and 1f, the upper web 90, i.e., the transverse ribs, is above the longitudinal ribs; referring to fig. 1g and fig. 1h, the longitudinal truss 100 and the transverse truss 110 are welded together by upper chord steel bars, lower chord steel bars and wave-shaped auxiliary steel bars, wherein in the present embodiment, the upper chord steel bars and the lower chord steel bars of the longitudinal truss 100 are longitudinal steel bars of the upper net piece 90 and longitudinal steel bars of the lower net piece 80, respectively, and the upper chord steel bars and the lower chord steel bars of the transverse truss 110 are transverse steel bars of the upper net piece 90 and transverse steel bars of the lower net piece 80, respectively, so it can be understood that the longitudinal truss 100 and the transverse truss 110 referred to in the present embodiment refer to respective web steel bars.

It can be understood that the present embodiment provides a conveying system, which includes the first conveying device 10, the second conveying device 20, the third conveying device 30, the first lifting device 40, the second lifting device 50, and the telescopic device 60, as described above, and the setting method between the devices is as described in detail above. For the reinforcement cage with a large longitudinal length (along the first direction and the longitudinal direction), please refer to fig. 2a, fig. 3a and fig. 4d, and a plurality of conveying systems are arranged at intervals along the first direction, so that the reinforcement cage is supported as a whole. In addition, for the reinforcement cage with a large longitudinal length, each module of the reinforcement cage already meets the length of an actual project before being transmitted, specifically, the upper mesh sheet 90 and the lower mesh sheet 80 are all a plurality of mesh sheets with small specifications, and longitudinal ribs are connected through connectors to manufacture mesh sheets with large specifications.

Preferably, the upper mesh sheet 90, the lower mesh sheet 80 and the longitudinal truss 100 are all welded by the welding machine 70, and in addition, in the process of forming the reinforcement cage, the connection between the upper mesh sheet 90 and the lower mesh sheet 80 and the longitudinal truss 100 is manual welding. Therefore, the labor consumption can be reduced, the welding quality is improved, and the welding efficiency is improved.

Optionally, before the first conveyor 10 is used to support and drive the lower mesh 80 to move in the first direction, the method further includes a step S11 of adjusting the height of the upper surface of the first conveyor 10 to be flush with the height of the finished platform 71 of the welding machine 70. In this way, the lower mesh sheet 80 processed by the welder 70 can be smoothly transferred to the upper surface of the first transfer device 10. Similarly, before the longitudinal girder 100 in the lying state is supported and driven by the second conveyor 20 to move in the first direction, the method for manufacturing a reinforcement cage further includes adjusting the height of the upper surface of the second conveyor 20 to be level with the height of the finished platform 71, so that the longitudinal girder 100 is smoothly transferred to the upper surface of the second conveyor 20.

Specifically, referring to fig. 2a and 3b, the first conveying device 10 is disposed on the first lifting device 40, and the vertical positions of the first conveying device 10 and the second conveying device 20 are adjusted by the lifting of the first lifting device 40.

Optionally, after the transverse girder 110 is welded to the lower mesh 80, the method for manufacturing a steel reinforcement cage further includes a step S51, referring to fig. 3e, of adjusting the vertical position of the first conveyor 10 (by the first lifting device 40) so that the top of the longitudinal girder 100 is lower than the finished platform 71 of the welding machine 70 by a predetermined value. With such a configuration, a height difference can be reserved for the upper mesh 90 to be transmitted to the upper side of the longitudinal ribs.

Further, the predetermined value is between 300mm and 500 mm.

Optionally, before the third conveyor 30 is used to support and drive the upper mesh sheet 90 to move in the first direction, the method for manufacturing a reinforcement cage further includes a step S61 of adjusting the height of the upper surface of the third conveyor 30 to be flush with the height of the finished platform 71 of the welding machine 70.

Specifically, referring to fig. 4a, the third conveying device 30 is disposed on the second lifting device 50, and the vertical position of the third conveying device 30 is adjusted by the lifting of the second lifting device 50.

In one particular embodiment, the first lifting device 40 and the second lifting device 50 are both scissor lifts.

Optionally, before the transverse girders 110 are welded to the lower mesh 80, the method for manufacturing the reinforcement cage further includes a step S52 of adjusting the vertical length of the transverse girders 110 to fit the tops of the transverse girders 110 to the tops of the longitudinal girders 100. Actually, because the positions of the transverse bars and the longitudinal bars in the upper mesh 90 and the lower mesh 80 are different, when the reinforcement cage is welded, the vertical length of the transverse truss 110 is adjusted, specifically, the vertical length of the transverse truss 110 is configured to be larger than the vertical length of the longitudinal truss 100 by about two bar diameters, so that after the transverse truss 110 is welded to the lower mesh 80, the top of the transverse truss 110 is higher than the top of the longitudinal truss 100 by one bar diameter, which is convenient for welding the upper mesh 90 to the longitudinal truss 100 and the transverse truss 110. The transverse truss 110 of the present embodiment is generally formed by manual forming.

Optionally, after the lower mesh 80 laying stage, the truss laying stage, and the upper mesh 90 laying stage are all completed, the reinforcement cage manufacturing method further includes step S90:
