[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains; the terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0034] like Figures 1 to 8 As shown, the present application provides a cross-rebar and automatic cross-rebar equipment for a steel truss thin-walled plate, comprising a base 100 and a cross-rebar member 200. Support assemblies 300 are provided on both sides of the top of the base 100. The support assembly 300 includes a front entry cylinder 310 and a rear entry cylinder 320. A spacing 330 is provided between the front entry cylinder 310 and the rear entry cylinder 320. The ends of the cross-rebar member 200 successively pass through the front entry cylinder 310 and the rear entry cylinder 320.

[0035] A clamping assembly 400 is provided between the front entry tube 310 and the rear entry tube 320. The clamping assembly 400 is movably connected within a spacing 330. The clamping assembly 400 includes two symmetrically arranged clamping plates 410. The clamping plates 410 movably contact the cross-rebar member 200.

[0036] The clamping assembly 400 is provided with a driving assembly 500 . After the clamping assembly 400 clamps the cross-rebar member 200 , the driving assembly 500 moves transversely to achieve a cross-rebar member 200 cross-rebar operation.

[0037] Further specific explanation: The design of the driving component 500 is to drive the clamping plate 410 to move horizontally back and forth, thereby driving the cross-reinforcement member 200 in the clamping plate 410 to move horizontally back and forth, and the end of the cross-reinforcement member 200 enters the inner side of the crest section of the corresponding web reinforcement 210, and the front entry cylinder 310 and the rear entry cylinder 320 form support for the cross-reinforcement member 200. As the cross-reinforcement member 200 continues to move horizontally, horizontal threading is achieved.

[0038] Specifically, the driving assembly 500 includes an inverted U-shaped fixing frame 510, the two sides of which are fixed to the front entry cylinder 310 and the rear entry cylinder 320. The inner side of the fixing frame 510 is slidably connected to a connecting cover 520, and the connecting cover 520 has a clamping assembly 400.

[0039] The inner side of the fixing frame 510 is rotatably connected with a threaded rod 530, and a limiting rod 540 is fixed inside the fixing frame 510. The threaded rod 530 and the connecting cover 520 are threadedly connected, and the limiting rod 540 and the connecting cover 520 are slidingly connected. The connecting cover 520 is respectively sleeved and connected to the threaded rod 530 and the limiting rod 540, and a driving part 550 is provided on the threaded rod 530.

[0040] Further specific explanation: the driving member 550 adopts a motor, the motor is fixed on the fixed frame 510, the output shaft of the motor is fixedly connected to the end of the threaded rod 530, the motor drives the threaded rod 530 to rotate forward and reverse, and the threaded rod 530 drives the connecting cover 520 to move back and forth laterally, wherein the limiting rod 540 has a limiting effect on the connecting cover 520, so that the connecting cover 520 cannot rotate circumferentially with the threaded rod 530, and can only move axially with the threaded rod 530, so that the cross-rebar member 200 clamped on the inner side of the clamping plate 410 can move stably laterally to achieve threading.

[0041] Specifically, the clamping assembly 400 further includes a connecting plate 420 fixed to the back of the clamping plate 410, and there are two connecting plates 420;

[0042] The bottom end of the connecting cover 520 is provided with a through slot 430 , and the two connecting plates 420 are slidably connected inside the through slot 430 ;

[0043] A lead screw 440 with opposite thread directions at both ends is rotatably connected inside the through slot 430, a limit shaft 450 is fixed inside the through slot 430, the ends of the two connecting plates 420 penetrate into the through slot 430, and are respectively threadedly connected to the two ends of the lead screw 440, the connecting plates 420 and the limit shaft 450 are slidably connected, and the connecting plates 420 are respectively sleeved and connected to the lead screw 440 and the limit shaft 450, and a power part 460 is provided at one end of the lead screw 440.

[0044] Further specific explanation: the power part 460 adopts a motor, the motor is fixed to the outside of the connecting cover 520, the output shaft of the motor is fixedly connected to one end of the screw 440, and the motor drives the screw 440 to rotate forward and reverse; in addition, the limiting shaft 450 limits the connecting plate 420, so that the connecting plate 420 cannot rotate circumferentially with the screw 440 when driven by the screw 440, and can only move axially with the screw 440.

[0045] Specifically, a front inlet 311 and a rear inlet 321 are respectively formed transversely through the interior of the front entry tube 310 and the rear entry tube 320 , and the central axes of the front inlet 311 and the rear inlet 321 are on the same straight line.

[0046] Specifically, the front inlet 311 and the rear inlet 321 are both trumpet-shaped.

[0047] Further specific explanation: The ports of the front entrance 311 and the rear entrance 321 are both designed in a trumpet shape to facilitate the threading of the cross-rebar member 200. The cross-rebar member 200 enters the front entrance 311 after passing through the port of the front entrance 311, and enters the rear entrance 321 after passing through the port of the rear entrance 321.

[0048] Specifically, it also includes a reinforcing component 600, which is fixed on one side of the rear entry tube 320. The cross-reinforcement member 200 moves through the reinforcing component 600, and the reinforcing component 600 is used to stably guide the cross-reinforcement member 200.

[0049] Further specific explanation: During the use of the reinforcement component 600, the reinforcement component 600 is unfolded and extends into the corresponding wave crest of the web reinforcement 210, providing the final stable support and transportation for the cross-crossing steel bar 200; when the reinforcement component 600 is not in use, the reinforcement component 600 is contracted together, and the overall structure is shorter, which does not affect the horizontal penetration of the cross-crossing steel bar 200.

[0050] Specifically, the reinforcement assembly 600 includes a plurality of conveying rings 610 , and a plurality of balls 620 are arrayed on the inner side of each conveying ring 610 , and the balls 620 are movably connected to the cross-reinforcement member 200 ;

[0051] To be further explained in detail, the cross-rebar member 200 contacts the ball bearings 620 when in the conveying ring 610 . The ball bearings 620 help to reduce the contact friction between the cross-rebar member 200 and the conveying ring 610 , thereby facilitating the rapid conveyance of the cross-rebar member 200 .

[0052] The two adjacent conveying rings 610 are fixedly connected by a telescopic rod 630. The conveying ring 610 on one side is fixedly connected to one side of the rear entry tube 320. A connecting ring is fixed on the conveying ring 610 on the other side, and a telescopic component 640 is provided at the bottom of the connecting ring.

[0053] Further specific explanation: The telescopic component 640 is designed to drive the connecting ring towards the rear entry tube 320 or away from the rear entry tube 320; when the reinforcement component 600 is not used, the telescopic component 640 drives the connecting ring towards the rear entry tube 320, and the telescopic rod 630 is shortened, reducing the lateral length, thereby facilitating the movement of the entire device; when the reinforcement component 600 is used, the telescopic component 640 drives the connecting ring away from the rear entry tube 320, and the telescopic rod 630 is extended, and several conveying rings 610 are unfolded, thereby extending the conveying path of the cross-rebar, which can effectively reduce the situation where the cross-rebar end of the cross-rebar 200 sags and tilts due to gravity due to the short conveying path of the cross-rebar 200, making it inconvenient for subsequent effective threading.

[0054] Specifically, the telescopic assembly 640 includes a power source 641 fixed to the lower side of the end of the rear entry tube 320. A connecting block is fixed to the end of the power source 641, and the connecting block is fixedly connected to the connecting ring.

[0055] To be further described in detail, the power source 641 is an electric telescopic rod, which is fixed to one side of the rear entry tube 320 , and the free end of the electric telescopic rod is fixedly connected to the connecting block.

[0056] Specifically, a roller is provided at the bottom end of the base 100 , and a handle is provided on one side of the base 100 .

[0057] Further specific description: The design of the wheels and handle makes it easy to push the device to move.

[0058] During actual use of the cross-rebar and automatic cross-rebar device for thin-walled panels of a steel truss according to an embodiment of the present application: in the initial state, the clamping plate 410 is located within the spacing 330 and close to the side of the front entry tube 310. During operation, the handrail is used to push the device to one side of the steel truss so that the reinforcement assembly 600 is close to the crest position of the web reinforcement 210. Then, the electric telescopic rod of the power source 641 is activated, the free end of the electric telescopic rod is extended, the connecting ring is away from the rear entry tube 320, and the plurality of conveying rings 610 are extended and deployed toward the inner side of the crest section of the web reinforcement 210.

[0059] After the preparation is completed, one end of the cross-reinforcement member 200 is manually inserted into the front entry tube 310 and the rear entry tube 320 in sequence. After the cross-reinforcement member 200 passes through the front entrance 311 and the rear entrance 321, the motor of the power member 460 is started, and the motor drives the lead screw 440 to rotate forward, and the two clamping plates 410 move toward each other to clamp and fix the cross-reinforcement member 200. Then, the motor of the driving member 550 is started, and the motor drives the threaded rod 530 to rotate forward, and the connecting cover 520 moves horizontally from front to rear, synchronously dragging the cross-reinforcement member 200, and the cross-reinforcement member 200 moves toward the rear side;

[0060] After the clamping plate 410 moves to one side of the rear entry tube 320, the motor of the power member 460 rotates in the reverse direction, the clamping plate 410 releases the clamping fixation on the transverse steel bar 200, and at the same time the motor of the driving member 550 rotates in the reverse direction, driving the connecting cover 520 and the clamping plate 410 to move forward laterally toward one side of the front entry tube 310;

[0061] Then restart the motor of the power part 460, and the motor drives the screw 440 to rotate forward, and the cross-rebar part 200 is clamped again through the clamping plate 410. At the same time, the motor of the driving part 550 drives the threaded rod 530 to rotate forward, and the connecting cover 520 continues to move horizontally from front to back, synchronously dragging the cross-rebar part 200, and the cross-rebar part 200 moves toward the rear side. The cycle operation is repeated according to the above operation method. The cross-rebar part 200 passes through the rear entry tube 320 and enters the conveying ring 610, and finally enters the inner section of the wave peak of the corresponding web reinforcement 210, realizing the horizontal penetration of the cross-rebar part 200.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. A person skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
