[0002] Grid stirrups are formed by longitudinal and transverse steel bars arranged at a certain interval and intersected to form a grid. All intersections are welded by resistance pressure welding that meets specific requirements to form a welded steel mesh, which is used as stirrups for reinforced concrete components. Formed grid stirrups are used as shear reinforcement for reinforced concrete beams. They have been included in the standards of many countries abroad and have been used in many projects. In the construction field of my country, they are mainly used as "reinforcements" in reinforced concrete to increase the strength and toughness of concrete.

[0003] In the traditional construction industry, the grid stirrups used in construction need to be manually loaded, which consumes a lot of man-hours, and the working environment is poor, which affects the health of workers.

In this embodiment, it needs to be explained that the second lower equipment frame 4 and the bottom frame 1 It is also possible to use another set of sliding components 2 to slide and connect to make slight adjustments to the position of the second lower equipment frame 4. In order to better realize the automatic loading of the grid stirrups 36, for the convenience of work, it is only necessary to move the first lower equipment frame 3 on one side to adapt to the adjustment of grid stirrups 36 of different specifications. The second lower equipment frame 4 on the other side is fixed to the base frame 1 relative to the subsequent adjustment of the specifications of the grid stirrups 36 by the first lower equipment frame 3. The second lower equipment frame 4 is fixed and does not move.

The invention can adapt to all specifications of the cantilever assembly 21 in which the size of the grid stirrup 36 is larger than that of the cantilever assembly 21 and has wide applicability.

[0039] The cantilever assembly 21 includes a left cantilever 13 and a right cantilever 14 . The left cantilever 13 and the right cantilever 14 are respectively disposed on both sides of the conveying chain 12 , and a gap is reserved between the left cantilever 13 and the right cantilever 14 and the conveying chain 12 .

[0040] Stoppers 17 are fixedly disposed at both ends of the mounting base plate 7 , and a buffer block 18 is attached to one end of the stopper 17 facing inward, so as to effectively limit and remind the movement of the mounting platform 9 on the motion guide rail 7 .

[0041] A transmission rack 15 is provided inside the motion guide rail 8, and the transmission rack 15 is fixedly connected to the mounting base plate 7. The transmission rack 15 meshes with a transmission gear 16, and a mounting hole is provided at the center of the transmission gear 16. The output end of the travel motor 10 is adapted to be connected to the mounting hole.

[0042] The working principle of the stirrup transport mechanism is as follows: the travel motor 10 drives the transmission gear 16 along the transmission rack 15 to drive the whole to do forward and backward travel movement on the motion guide rail 8. After reaching the transport position according to the on-site work instructions, the grid stirrups 36 are transported to the transport chain 12 near one end of the transport gear 20, and the transport motor 11 starts working. The grid stirrups 36 placed on the transport chain 12 automatically move forward, and all the grid stirrups 36 are transported to the transport chain 6, thereby realizing the automated transport of the grid stirrups 36. The length of the cantilever assembly 21 and the transport chain 12 can be customized according to the specific construction site, and multiple grid stirrups 36 can be transported at one time.

[0043] The stirrup movable support mechanism includes a fixed seat 23, a first rotating shaft 24, a rotating arm 25, a swing connecting rod 26, a second rotating shaft 27, a telescopic cylinder 28 and a limit assembly. The upper equipment frame 5 is fixedly provided with a fixed seat 23, and the fixed seat 23 is a 2N+1 group arranged side by side, where N is a positive integer. A rotatable first rotating shaft 24 is passed through the fixed seat 23, and one end of the first rotating shaft 24 extends into the lower end of the rotating arm 25 and is fixedly connected thereto. A through hole is opened at the upper end of the rotating arm 25, and a fixed second rotating shaft 27 is passed through the through hole. One end of the second rotating shaft 27 is inserted into the swing connecting rod 26 and is rotatably connected thereto. In this embodiment, the telescopic cylinder 28 is one, The rotatable connection with the N+1th group of second rotating shafts 27 (i.e., the second rotating shafts 27 arranged at the center position) can meet general working requirements. In actual use, several telescopic cylinders 28 can be installed to work synchronously according to factors such as the quality of the grid stirrups 36 on site, and the present invention is not limited thereto; the other end of the second rotating shaft 27 is rotatably connected to the output end of the telescopic cylinder 28 through a fisheye joint 32; the limiting components are arranged in N+1 groups side by side, and the limiting components are attached to the vertical outer side of the rotating arm 25 and limit the position, and the limiting components are spaced apart from the fixed seat 23, which can not only achieve the best limiting effect, but also reduce the manufacturing cost of the device.

[0044] An avoidance groove 31 is provided on the swing link 26, and the avoidance groove 31 is in a step shape. Since the ends of the steel bars in the grid stirrups 36 will be slightly deformed during the cutting process, the step-shaped avoidance groove 31 can allow the grid stirrups 36 to be placed completely horizontally as a whole, and its ends will not be placed to lift the whole, making the grid stirrups 36 unstable, thereby improving the accuracy of the placement of the grid stirrups 36.

[0045] The limiting assembly includes a limiting block 29 and a limiting screw 30 . The upper equipment frame 5 is fixedly provided with the limiting block 29 .

[0046] A first bearing 33 is provided in the fixed seat 23, and the first rotating shaft 24 is adapted to be installed thereon; a second bearing 34 is provided in the swing link 26, and the second rotating shaft 27 is adapted to be installed thereon, thereby reducing friction between the fixed seat 23 and the first rotating shaft 24, and between the swing link 26 and the second rotating shaft 34, making rotation smoother and reducing energy consumption, and also protecting the first rotating shaft 24 and the second rotating shaft 34, so that the first rotating shaft 24 and the second rotating shaft 34 can be kept in the correct position to work.

[0047] An annular protrusion 35 is provided on the second rotating shaft 27 , and the annular protrusion 35 is provided between the rotating arm 25 and the swing link 26 .

[0048] The working principle of the stirrup movable support mechanism is as follows: the telescopic cylinder 28 extends out, driving the second rotating shaft 27 to change the rotating arm 25 into a vertical state. At this time, the rotating arm 25 is against the limit screw 20 to ensure the vertical effect of the rotating arm 25. Then the grouped grid stirrups 36 are unloaded along the swing link 26 in turn, and the ends of the stirrups are smoothly placed in the avoidance groove 9, so that the stirrups are placed stably as a whole. After the grouped grid stirrups 36 are unloaded, the telescopic cylinder 28 slowly retracts again, driving the rotating arm 25 to rotate to an inclined state. At this time, the second rotating shaft 27 cooperates with the first rotating shaft 24 to drive the swing link 26 to slowly descend vertically, and the grouped grid stirrups 36 also slowly descend synchronously. The grouped grid stirrups 36 not only get the buffer for unloading, but the telescopic cylinder 28 can also control its unloading speed.

[0049] The working principle of the present invention is as follows: the manually operated crane drops the grouped grid stirrups 36 to a position 10-30 mm above the swing link 26 on the first lower equipment frame 3, and at the same time, close to the stirrup transport mechanism on the first lower equipment frame 3 (when the specifications of the grid stirrups 36 change, the movable distance of the first lower equipment frame 3 can be adjusted), and the manually operated machine slightly adjusts the second lower equipment frame 4 to a fixed position, and the second lower equipment frame 4 is used for a clearance when the crane drops materials; the manually operated crane continues to descend, and at the same time, the telescopic cylinder 28 extends, the entire rotating arm 25 is in a vertical state, and the grid stirrups 36 fall on the swing link 26, and the ends of the grid stirrups 36 fall into the avoidance groove 31;

[0050] The traveling crane is pulled out, the cantilever assembly of the stirrup transport mechanism is inserted into the grid stirrup 36, the telescopic cylinder 28 is retracted, slowly retracted, driving the rotating arm 25 to rotate to an inclined state, and driving the swing connecting rod 26 to slowly descend vertically, and the grouped grid stirrups 36 are also synchronously and slowly descended to the transport chain 12 close to one end of the transport gear 20, the transport motor 11 starts to work, and the grid stirrups 36 placed on the transport chain 12 automatically move forward, and all the grid stirrups 36 are transported to the transport chain 6, and the stirrup transport mechanism moves forward a distance to dock with the next station to realize automatic loading.

[0051] The present invention improves the overall working efficiency of feeding the grid stirrups 36, improves the working environment, realizes 24-hour uninterrupted production, realizes fully automated and efficient production, and promotes the sustainable development of the industry; it protects the personal safety of operators, can automatically adjust the spacing according to the incoming materials and product model specifications, is compatible with products of various specifications, and the feeding action is stable and reliable.
