[0031] The following further describes the present utility model in detail with reference to the drawings and specific embodiments.

[0032] As Figures 1-7 shown, the stirrup magazine positioning mechanism for the production of the steel bar skeleton of highway precast box girders includes: a stirrup magazine 1, a moving wheel set 2, and a wedge - shaped positioning tooling 3.

[0033] The stirrup magazine 1 includes a magazine bottom plate 11, a magazine support frame 12, a lifting ring 14, and a suspension rod 13 arranged above the magazine bottom plate 11; the magazine support frame 12 is connected to one end of the magazine bottom plate 11 and the suspension rod 13. A stirrup skeleton 4 is suspended on the suspension rod 13, and the magazine bottom plate 11 supports the bottom of the stirrup skeleton 4; the lifting rings 14 are arranged at both ends of the suspension rod 13 or on the suspension rod 13 and the magazine support frame 12. It is convenient to hoist the stirrup magazine 1 as a whole and the stirrup skeleton 4 suspended on the suspension rod 13 of the stirrup magazine 1.

[0034] The magazine bottom plate 11 includes longitudinal beams, cross - beams, and a bottom plate body. The longitudinal beams and cross - beams are connected into a horizontal frame, and the bottom plate body is paved on the frame. The length direction of the longitudinal beam is the length direction of the magazine bottom plate 11, and the length direction of the cross - beam is the width direction of the magazine bottom plate 11. A limit guide plate 15 is also arranged on the top of the magazine bottom plate 11. The length direction of the limit guide plate 15 is the same as the length direction of the magazine bottom plate 11. The two limit guide plates 15 are arranged at intervals along the width direction of the magazine bottom plate 11. The distance between the two limit guide plates 15 is the width of the bottom of the stirrup skeleton 4, or the width of the bottom stirrups of the stirrup skeleton 4, so as to limit the bottom of the stirrup skeleton 4 between the two limit guide plates 15.

[0035] There are two suspension rods 13, which are arranged parallel and horizontally. One end of the suspension rod 13 is welded and fixed to the magazine support frame 12, and the other end is a cantilever end. The stirrup skeleton 4 penetrates into from the cantilever ends of the two suspension rods 13.

[0036] The moving wheel set 2 is arranged at the bottom of the magazine bottom plate 11 and is in sliding or rolling cooperation with the magazine bottom plate 11.

[0037] There are multiple groups of moving wheel sets 2, and the multiple groups of moving wheel sets 2 are arranged at intervals along the length direction of the magazine bottom plate 11; each group of moving wheel sets 2 includes two moving wheels arranged at intervals along the width direction of the magazine bottom plate 11. The two moving wheels of each group of moving wheel sets 2 respectively support under the two longitudinal beams of the magazine bottom plate 11.

[0038] As Figure 7 shown, the moving wheel set 2 includes a support column 21 and a roller 22 rotatably arranged at the top of the support column 21. The support column 21 is used to provide support for the stirrup magazine 1, and the roller 22 is used to provide power for the stirrup magazine 1 to move horizontally in the longitudinal direction.

[0039] A shaft hole is formed in the side wall of the support column 21 near its top end. The roller 22 includes a roller shaft and a rolling wheel sleeved on the roller shaft. The roller shaft is arranged in the shaft hole of the support column 21. The rolling wheel is connected to the support column 21 through the roller shaft and can rotate around the roller shaft. The cooperation between the stirrup magazine 1 and the moving wheel set 2 of the present utility model realizes the translation of the stirrup magazine 1 along its length direction, so that the position of the stirrup magazine 1 can be adjusted as the number of stirrup skeletons 4 on the stirrup magazine 1 decreases, shortening the moving distance of each stirrup in the stirrup skeleton 4 and improving the production efficiency of the steel bar skeleton.

[0040] A plurality of wedge-shaped positioning toolings 3 are arranged at intervals along the length direction of the magazine bottom plate 11. For example, in this embodiment, two wedge-shaped positioning toolings 3 are arranged at intervals along the length direction of the magazine bottom plate 11. Each wedge-shaped positioning tooling 3 includes a wedge block 31, a jacking component 32, a positioning component 33, a tooling support plate 34, a tooling guide plate 35 and a vertical adjustment component 36.

[0041] The positioning component 33 is arranged at the bottom of the magazine bottom plate 11; the wedge block 31 is arranged below the magazine bottom plate 11; the jacking component 32 is connected to the wedge block 31 and is used to drive the wedge block 31 to lift and lower, and abut and position or separate from the positioning component 33.

[0042] The wedge block 31 is provided with a notch; the positioning component 33 includes a positioning block, and the positioning block is inserted and matched with the notch. The top of the wedge block 31 is an open structure, and a notch is arranged on one side, and the opening direction of the notch is the length direction of the stirrup magazine 1.

[0043] The vertical adjustment component 36 penetrates through the tooling guide plate 35 located above the tooling support plate 34; the jacking component 32 is installed on the tooling guide plate 35.

[0044] Specifically, the vertical adjustment component 36 includes a vertical guide rod and an adjustment nut threadedly connected to the vertical guide rod; the adjustment nut is locked at both ends of the tooling guide plate 35. The vertical guide rod is perpendicular to the plate surfaces of the tooling guide plate 35 and the tooling support plate 34, while the plate surfaces of the tooling guide plate 35 and the tooling support plate 34 are horizontally arranged. By loosening the adjustment nut, the height of the tooling guide plate 35 can be adjusted along the vertical guide rod. After reaching the target height, the adjustment nut is tightened to fix the tooling guide plate 35 at the target height. Since the jacking component 32 is fixedly connected to the tooling guide plate 35, the height of the jacking component 32 is fixed at the required height. The jacking component 32 can include a hydraulic pump or a jacking motor. The jacking motor makes the wedge block 31 correspond to the positioning block through the jacking wedge block 31, and the positioning block is inserted into the slot of the wedge block 31 to limit the movement of the stirrup magazine 1 and achieve the positioning of the stirrup magazine 1.

[0045] The vertical adjustment component 36 further includes a slot plate 38 and two vertical angle steels 37; the slot plate 38 is located between the two vertical angle steels 37. The bottom of the vertical angle steel 37 is fixedly connected to the top of the tooling guide plate 35, and a guide slot is provided on the vertical angle steel 37 with its length direction perpendicular to the top of the tooling guide plate 35; both sides of the slot plate 38 are inserted into the guide slots of the two vertical angle steels 37, and the slot plate 38 can slide along the guide slot. The slot plate 38 is connected to the wedge block 31 and the jacking component 32 and rises and falls synchronously with the wedge block 31.

[0046] During operation, first, the stirrup magazine 1 is hoisted and placed on the moving wheel set 2 as a whole and horizontally moved along the longitudinal direction of the stirrup skeleton 4 to a rough position. The longitudinal direction of the stirrup skeleton 4 is the longitudinal direction of the box girder steel bar skeleton, which can also be called the length direction of the box girder steel bar skeleton or the stirrup skeleton 4. Since the moving wheel set 2 cannot provide precise positioning for the stirrup magazine 1, to achieve the precise positioning function, when the stirrup magazine 1 is roughly in place, the jacking component 32 of the wedge-shaped positioning tooling 3 starts to work, jacks up the wedge block 31, and makes the inclined surface at the upper end of the wedge block 31 engage with the positioning part 33 at the bottom of the upper stirrup magazine 1, so that the stirrup magazine 1 falls to the set target position, thereby achieving the precise positioning of the stirrup magazine 1.

[0047] The utility model guides the stirrup magazine 1 to move in a specific direction through the moving wheel set 2 and suspends the stirrup skeleton 4 by using the suspension rod 13, which can realize the overall feeding of the stirrup magazine 1; and by using the cooperation between the lifting and lowering of the wedge block 31 of the wedge-shaped positioning tooling 3 and the positioning part 33 at the bottom of the stirrup magazine 1, the precise positioning of the stirrup magazine 1 is realized, thus integrally solving the operation processes of transporting, feeding, and positioning of the stirrup semi-finished products, and providing a basic guarantee for the subsequent automated production of the precast box girder steel bar skeleton.

[0048] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
