Description

Technical Field

[0001] The utility model relates to the technical field of reinforcement stacking auxiliary equipment, in particular to a stirrup stacking platform. Background Art

[0002] Box girder is a type of beam in bridge engineering, which is divided into single box and multiple boxes. It is hollow inside and has flanges on both sides of the upper part, similar to a box, hence the name. Box girders of reinforced concrete structures are divided into prefabricated box girders and cast-in-place box girders. Box girders prefabricated in an independent site can be erected in combination with a bridge erection machine after the lower project is completed, which can speed up the progress of the project and save construction time. Box girder stirrups are used to meet the shear strength of the oblique section and connect the main force-bearing reinforcement and the mixed reinforcement skeleton in the compression zone. Traditional stirrup production first uses a bending and cutting machine to bend the steel bars to obtain semi-finished stirrups, and then obtains finished stirrups by robot welding. During welding, the overlapping parts at both ends of the stirrups are completed in advance so that the axes of the two overlapping ends tend to be parallel, and then arc welding is used to weld the overlapping parts of the workpiece.

[0003] At present, in the stirrup welding stage, the transportation of semi-finished stirrups and finished stirrups before and after the welding robot is mainly to simply stack the stirrups on the stacking platform for lifting, and directly lift one end of the stacking platform when unloading, and the semi-finished stirrups are scattered on the work surface, and then transported to the welding work platform by a handling robot or manually, so that the welding robot can weld, and then the finished stirrups are transported to the stacking platform by a handling robot or manually for re-stacking. Since stirrups are used in large quantities and are very heavy in reinforced concrete structures, the method of manually lifting stirrups for stacking and unstacking is not only time-consuming and labor-intensive, but also the heavy steel bars make it easy for workers to get injured during the lifting process. The method of unstacking and stacking by handling robots causes safety problems because the stirrups are easily collapsed when stacked too high. Utility Model Content

[0004] The problem to be solved by the utility model is to provide a stirrup stacking platform in view of the above-mentioned deficiencies existing in the prior art, which drives the uppermost layer of stirrups to be flush with the inlet and outlet ends of the welding platform by means of mechanical lifting, and limits the stacked stirrups in the circumferential direction by means of limiting rods, so that a handling robot can transfer the uppermost layer of stirrups to the welding work platform, which has the advantages of improving the transportation efficiency of stirrups before and after the welding process, avoiding the collapse of the stirrup stack, and reducing safety hazards.

Then the lifting drive drives the stirrup platform to rise at a fixed point so that the top layer of semi-finished stirrups is flush with the feeding and discharging ends of the welding work platform, which is convenient for the handling robot to transfer the semi-finished stirrups to the welding work platform along the same path. If it is handled manually, it is only necessary to push the semi-finished stirrups horizontally onto the welding work platform, which is beneficial to improve the transportation efficiency of the stirrups before the welding process; when unloading, the lifting drive drives the stirrup platform to descend at a fixed point. , so that a gap approximately equal to the thickness of the stirrups is reserved between the top layer of finished stirrups and the inlet and outlet ends of the welding work platform, and then the finished stirrups are transferred to the top of the stirrup platform by the handling robot, and slide downward and stacked on the top layer of finished stirrups in the manner that the circumferential inner wall and / or the circumferential inner wall of the stirrups hit these limit rods. If they are handled manually, it is only necessary to push the finished stirrups horizontally onto the top layer of finished stirrups, which is beneficial to improving the transportation efficiency of the stirrups after the welding process; in addition, these limit rods are determined on these mounting holes according to the circumferential shape of the stirrups, have good flexibility, and cooperate with the sliding penetration of the binding mouth, which does not affect the lifting and lowering of the stirrup support plate, and is convenient for locating the position of the top layer of steel bars, avoiding the collapse of the stirrup stack, and is beneficial to reducing safety hazards.

[0031] In order to make the technical means, creative features, objectives and functions achieved by the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figure 1 , is a stirrup stacking platform disclosed in the utility model, comprising a frame 1, a pair of lifting drive members 2 symmetrically arranged on the frame 1, a stirrup support plate 3 arranged between the output ends of the pair of lifting drive members 2, four binding openings 4 opened on the stirrup support plate 3, and four limit components 5 detachably connected to the frame 1. Among them, the lifting drive member 2 is set as a screw-type linear module, these limit components 5 slide through the binding openings 4, and are installed and detached on the frame 1 by sliding and plugging. The stirrups on the stirrup support plate 3 are circumferentially limited by these limit components 5 and can be slid and detached along the length direction of the limit rod 53. In addition, in order to facilitate the binding and unbinding of the stirrups after stacking, there is a gap between at least one inner wall of the binding opening 4 and the stirrups on the stirrup support plate 3, so that the staff can pass the binding wire through the gap to bind and unbind the stirrups.

[0033] Reference Figure 2 and Figure 3The limiting assembly 5 includes a plurality of mounting holes 51 opened on the frame 1 and arranged below the stirrup support plate 3, a plurality of mounting grooves opened on the frame 1 and connected to the mounting holes 51, a plurality of limiting rods 53 respectively slidably penetrated through the binding openings 4 and plugged into the mounting holes 51, a blocking piece 54 arranged on the limiting rod 53 and abutting against the surface of the frame 1, and a limiting piece arranged on the limiting rod 53 and plugged into the mounting groove. Among them, the vertical projections of these binding openings 4 and the mounting openings overlap respectively, and the limiting rod 53 is set as a round tube so that the bottom end of the limiting rod 53 can pass through. In addition, the top end of the limiting rod 53 is inclined to form a guide rod 56, which is used to guide the stirrups to slide along the guide rod 56 to the main body of the limiting rod 53, and then fall onto the stirrup platform.

[0034] These mounting grooves are respectively arranged as a first mounting groove 521 connected to a single mounting hole 51, and a second mounting groove 522 connected to two adjacent mounting holes 51; the limiting pieces are respectively arranged as a first limiting piece 551 arranged on a single limiting rod 53 and plugged into the first mounting groove 521, and a second limiting piece 552 arranged between two adjacent limiting rods 53 and plugged into the second mounting groove 522; the single limiting rod 53 on the first limiting piece 551 is arranged relative to the circumferential outer wall or circumferential inner wall of the stirrups on the stirrup support plate 3, and the two adjacent limiting rods 53 on the second limiting piece 552 are respectively arranged relative to the circumferential outer wall and circumferential inner wall of the stirrups on the stirrup support plate 3.

If it is manually handled, it only needs to push the semi-finished stirrups horizontally to the welding work platform, which is conducive to improving the transportation efficiency of the stirrups before the welding process. When unloading, the lifting drive 2 drives the stirrup platform to descend at a fixed point, so that the top layer of finished stirrups and the inlet and outlet ends of the welding platform reserve a gap similar to the thickness of the stirrups, and then the finished stirrups are transferred to the top of the stirrup platform by the handling robot, and in the manner that the circumferential inner wall and / or the circumferential inner wall of the stirrups are against these limit rods 53, they slide downward and stack on the top layer of finished stirrups. If they are handled manually, they only need to push the finished stirrups horizontally to the top layer of finished stirrups, which is conducive to improving the transportation efficiency of the stirrups after the welding process. In addition, these limit rods 53 are determined on these mounting holes 51 according to the circumferential shape of the stirrups, have good flexibility, and cooperate with the sliding penetration of the binding mouth 4, which does not affect the lifting and lowering of the stirrup support plate 3, and is convenient for locating the position of the top layer of steel bars, avoiding the collapse of the stirrup stack, and is conducive to reducing safety hazards.
