[0024] The present utility model will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the sake of description, only parts related to the present utility model are shown in the drawings, rather than all the structures.

Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0028] Refer to Figures 1-5 As shown, in the embodiment of the present utility model, a stirrup clamping mechanism 10 is proposed, which can be used to clamp multiple stirrups 50 simultaneously. The stirrup clamping mechanism 10 includes a mounting base 11, a fixing plate 12, a movable plate 13, and a clamping driving member 14. At least two fixing plates 12 are fixedly arranged on the mounting base 11 at intervals along the first direction ( Figure 1 and Figure 2 the X direction and its reverse direction in Figure 1A plurality of first limiting grooves 121 are arranged at intervals in the Y direction and its reverse direction in the middle), and the orthographic projections of the first limiting grooves 121 on different fixing plates 12 in the first direction coincide, that is, the widths of the first limiting grooves 121 on different fixing plates 12 in the second direction and the distances between adjacent first limiting grooves 121 are equal. The movable plate 13 is arranged between two fixing plates 12. Second limiting grooves 131 are arranged at intervals on the movable plate 13 in the second direction. The second limiting grooves 131 are arranged in one-to-one correspondence with the first limiting grooves 121, and both the first limiting grooves 121 and the second limiting grooves 131 are provided with notches on one side in the third direction ( Figure 1 the Z direction in the middle). The stirrup 50 can enter both the first limiting groove 121 and the second limiting groove 131 at the same time. The clamping driving member 14 is connected to the movable plate 13 to drive the movable plate 13 to move in the second direction. The first direction, the second direction, and the third direction are perpendicular to each other in pairs.

[0029] In the above stirrup clamping mechanism 10, a plurality of first limiting grooves 121 and a plurality of second limiting grooves 131 are respectively arranged on the fixing plate 12 and the movable plate 13, and the movable plate 13 is driven to move by the clamping driving member 14, so that the second limiting grooves 131 on the movable plate 13 and the first limiting grooves 121 on the fixing plate 12 are displaced. The groove walls of the first limiting grooves 121 and the groove walls of the second limiting grooves 131 can synchronously clamp a plurality of stirrups 50 located in the plurality of first limiting grooves 121 and second limiting grooves 131. The stirrups 50 located in the first limiting grooves 121 extend in the first direction, and at least two fixing plates 12 are provided so as to ensure the correct direction of the stirrups 50.

[0030] In some embodiments, the stirrups 50 clamped by the stirrup clamping mechanism 10 are ribbed stirrups. The transverse ribs on the ribbed stirrups can enhance the bonding performance between the stirrups 50 and the concrete and better transmit stress. However, the setting of the transverse ribs will affect the clamping force of the stirrup clamping mechanism 10 on them. On this basis, refer to Figure 5 As shown, the second limiting groove 131 includes a main body groove 1311, a first clamping groove 1312, and a second clamping groove 1313. The main body groove 1311 has a notch in the same direction as the first limiting groove 121. The first clamping groove 1312 and the second clamping groove 1313 are arranged at intervals in the third direction on one side wall of the main body groove 1311 in the second direction and communicate with the main body groove 1311. In some embodiments, the third direction is the vertical direction. It can be understood that since the lower end of the stirrup 50 includes two steel bars, the width of the second clamping groove 1313 in the third direction is greater than the width of the first clamping groove 1312 in the third direction.

[0031] When clamping the stirrup 50, the front projections of the main body groove 1311 and the first limiting groove 121 in the first direction coincide. The stirrup 50 enters the first limiting groove 121 and the main body groove 1311. Under the action of the clamping driving member 14, the movable plate 13 moves along the second direction and pushes the stirrup 50 to move. The main body groove 1311 and the first limiting groove 121 are displaced until the two ends of the stirrup 50 respectively enter the first clamping groove 1312 and the second clamping groove 1313. The groove wall of the first limiting groove 121 blocks the communication ports between the first clamping groove 1312 and the second clamping groove 1313 and the main body groove 1311, so that the stirrup 50 is limited in the first clamping groove 1312 and the second clamping groove 1313. At this time, the clamping of the stirrup 50 by the stirrup clamping mechanism 10 is not affected by the transverse ribs on the stirrup 50, reducing the possibility of the stirrup 50 falling off the stirrup clamping mechanism 10.

[0032] In some embodiments, in order to improve the efficiency of the stirrup clamping mechanism 10, the stirrup clamping mechanism 10 can clamp multiple groups of stirrups 50 for manufacturing multiple groups of steel cage. The sizes of the stirrups 50 required for different steel cages may be different. On this basis, the movable plate 13 includes a plurality of movable plate bodies arranged at intervals along the second direction. Any movable plate body corresponds to the manufacturing of a group of steel cages. A plurality of clamping driving members 14 are arranged in one-to-one correspondence with the plurality of movable plate bodies to respectively drive the movable plate bodies to move along the second direction.

[0033] In some embodiments, the clamping driving member 14 adopts a clamping cylinder. In other embodiments, the clamping driving member 14 can also adopt driving structures such as an electric cylinder, a belt drive structure, and a sprocket drive structure.

[0034] In some embodiments, in order to improve the stability of the movable plate 13 when moving along the second direction, the stirrup clamping mechanism 10 further includes a guide rail extending along the second direction. The movable plate body is slidably arranged on the guide rail.

[0035] In an embodiment of the present utility model, a handling device is further proposed, including a translation mechanism 30, a lifting mechanism 40, and the stirrup clamping mechanism 10 in any of the above embodiments. The translation mechanism 30 is used to drive the stirrup clamping mechanism 10 to move along the first direction, and the lifting mechanism 40 is used to drive the stirrup clamping mechanism 10 to move along the third direction.

[0036] In some embodiments, the handling device further includes a frame 20. The frame 20 serves as an installation foundation. The translation mechanism 30 is arranged on the frame 20. The lifting mechanism 40 is arranged at the output end of the translation mechanism 30. The stirrup clamping mechanism 10 is arranged at the output end of the lifting mechanism 40. Specifically, the frame 20 straddles above the grasping station and the discharging station, and a storage trolley stacked with stirrups 50 is arranged at the grasping station.

[0037] Reference Figure 2 and Figure 3As shown, the frame 20 adopts a gantry structure, including columns 21, a guiding cross beam 22 and inclined support beams 23. The guiding cross beam 22 extends along a first direction. Two columns 21 are arranged at the two ends of the guiding cross beam 22 along the first direction to support the guiding cross beam 22. The two ends of the inclined support beams 23 are respectively connected to the guiding cross beam 22 and the columns 21 to improve the overall stability of the frame 20.

[0038] In some embodiments, to limit the stroke of the translation mechanism 30 so that the stirrup clamping mechanism 10 can accurately move between the grasping mechanism and the discharging station, a limit stop 24 is further provided on the frame 20. There are two limit stops 24, and the two limit stops 24 are arranged on the guiding cross beam 22 at intervals along the first direction. The output end of the translation mechanism 30 is located between the two limit stops 24. When the output end of the translation mechanism 30 abuts against the two limit stops 24, the stirrup clamping mechanism 10 is respectively located above the material grasping station and the discharging station.

[0039] Continue to refer to Figure 2 As shown, the translation mechanism 30 includes a moving cross beam 31, a translation motor 32 and a translation transmission assembly. The moving cross beam 31 is slidably arranged on the guiding cross beam 22 along the first direction. The translation motor 32 is fixed on the moving cross beam 31. The translation transmission assembly is configured to convert the rotational motion of the translation motor 32 into a linear motion and transmit it to the moving cross beam 31 so that the moving cross beam 31 moves along the first direction.

[0040] Specifically, two guiding cross beams 22 are arranged at intervals along a second direction, and the two guiding cross beams 22 are connected by a connecting cross beam. The moving cross beam 31 extends along the second direction, and its two ends are respectively slidably connected to the two guiding cross beams 22 to improve the moving stability of the moving cross beam 31.

[0041] In some embodiments, the translation transmission assembly includes a translation gear 33 and a translation rack 34. The translation gear 33 is arranged on the output shaft of the translation motor 32 and meshes with the translation rack 34 fixed on the guiding cross beam 22. When the translation motor 32 drives the translation gear 33 to rotate, under the action of the translation rack 34, the translation motor 32 drives the moving cross beam 31 to slide along the first direction.

[0042] In other embodiments, the translation transmission assembly adopts a lead screw transmission structure to convert the rotational motion of the translation motor 32 into a linear motion, which will not be elaborated here.

[0043] In some embodiments, the lifting mechanism 40 includes a fixed frame 41, a lifting beam 42, a lifting motor 43, and a lifting transmission assembly. The fixed frame 41 is fixed on the moving cross beam 31. The lifting beam 42 is slidably disposed through the fixed frame 41 in the third direction. The lifting motor 43 is disposed on the fixed frame 41. The lifting transmission assembly is configured to convert the rotational motion of the lifting motor 43 into a linear motion and transmit it to the lifting beam 42, so that the lifting beam 42 moves in the third direction.

[0044] In some embodiments, the lifting transmission assembly includes a lifting rack 45 and a lifting gear 44. The lifting rack 45 is fixed on the lifting beam 42 in the third direction. The lifting gear 44 is disposed on the output shaft of the lifting motor 43 and meshes with the lifting rack 45. When the lifting motor 43 drives the lifting gear 44 to rotate, the lifting rack 45 drives the lifting beam 42 to slide in the third direction.

[0045] In some embodiments, the handling device includes two groups of stirrup clamping mechanisms 10. The two groups of stirrup clamping mechanisms 10 are fixed to the output end of the same lifting mechanism 40 in the first direction to further improve the clamping effectiveness of the stirrups 50. Specifically, the stirrup clamping mechanism 10 is fixed to the lifting beam 42 through an adjustment beam. The adjustment beam extends in the first direction. The two groups of stirrup clamping mechanisms 10 are respectively disposed on both sides of the adjustment beam in the first direction.

[0046] After the stirrups 50 are welded, they are stacked in the storage trolley. A plurality of stirrups 50 corresponding to one steel reinforcement cage are taken as a group. When the handling device transports the stirrups 50, the lifting motor 43 is started. The clamping driving member in the stirrup clamping mechanism 10 drives the movable plate 13 so that the main body groove 1311 on the movable plate 13 coincides with the first limiting groove 121 on the fixed plate 12 in the orthographic projection. The stirrup 50 enters the first limiting groove 121 and the main body groove 1311. The clamping driving member drives the movable plate 13 in the reverse direction to limit the stirrup 50 in the mutually cooperating first limiting groove 121 and second limiting groove 131. Then the lifting motor 43 raises the stirrup clamping mechanism 10 to take out the stirrup 50 from the storage trolley. The translation motor 32 is started to drive the moving cross beam 31 to move in the first direction. After reaching the discharging point, the lifting motor 43 descends, and the stirrup clamping mechanism 10 is loosened. The stirrup 50 is placed at the designated station to complete the transportation of a plurality of stirrups 50.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here.
