[0003] When loading and unloading goods with the existing bridge-type transportation tooling, usually two clamping arms are used to clamp the goods to be transported. During the clamping process, a large number of fixing ropes need to be installed to improve its fixing efficiency. This kind of loading and unloading mechanism has the problem of low efficiency. To solve the above problems, a large-piece rapid loading and unloading device for bridge-type transportation tooling is proposed. Content of the Utility Model

Drive the fixing frames to open outwards by rotating the first motor clockwise, move the large-piece goods between the two fixing frames, and then rotate the first motor counterclockwise to move the two fixing frames inwards to place the large-piece goods between the two fixing frames to complete the preliminary fixation. At this time, the two clamping arms move inwards towards each other to clamp both sides of the large-piece goods, thereby improving the stability of the goods. By setting two groups of fixing mechanisms, on the one hand, the stability is improved, and on the other hand, the steps of installing fixing ropes are reduced, greatly improving the loading and unloading efficiency.

[0014] In a preferred embodiment, a cylinder is hinged to one side of the upper surface of the fixed beam, and the output shaft of the cylinder is hinged to the outer wall of one side of the moving plate.

[0015] Through the above technical solution, when unloading is required, the cylinder contracts to drive the moving plate to move to the right along the fixed beam. At this time, the center of gravity of the loading and unloading device shifts and tilts to one side, so as to facilitate the unloading of the goods.

[0016] In a preferred embodiment, both the first motor and the second motor are controlled by a PLC.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effect of the present utility model is: The present utility model provides a large-piece rapid loading and unloading device for a bridge transportation tooling.

[0018] When loading large-piece goods, first move the fixed beam to the upper end of the large-piece goods. The first motor rotates clockwise to drive the fixed frame to open outward. Move the large-piece goods between the two fixed frames. The first motor rotates counterclockwise to move the two fixed frames inward to place the large-piece goods between the two fixed frames to complete the preliminary fixation. At this time, the two clamping arms move inward towards each other to clamp both sides of the large-piece goods, thereby improving the stability of the goods. By setting two groups of fixing mechanisms, on the one hand, the stability is improved, and on the other hand, the steps of installing and fixing ropes are reduced, greatly improving the loading and unloading efficiency.

[0027] A fixed beam 1; fixed frames 2 are hinged on both the left and right sides thereof. First motors 3 are fixedly installed on the upper surfaces of both the left and right sides of the fixed beam 1. The end of the output shaft of the first motor 3 is fixedly installed with a first gear 4. A second gear 5 is fixedly installed on one side of the connection between the fixed frame 2 and the fixed beam 1. The first gear 4 and the second gear 5 are meshed. When it is necessary to load large-piece goods, first move the fixed beam 1 to the upper end of the large-piece goods. Drive the fixed frames 2 to open outwards by clockwise rotation of the first motor 3, move the large-piece goods between the two fixed frames 2, and drive the two fixed frames 2 to move inwards by counterclockwise rotation of the first motor 3 to place the large-piece goods between the two fixed frames 2 to complete preliminary fixation;

[0028] The connecting seat 13 is fixedly installed on the lower walls on the left and right sides of the fixed beam 1. Two clamping arms 6 are hinged inside each of the two connecting seats 13. A third gear 7 is fixedly installed on one side of each of the two clamping arms 6. The two third gears 7 mesh with each other. Second motors 8 are fixedly installed on the left and right sides of the lower wall of the fixed beam 1. The first motor 3 and the second motors 8 are both controlled by a PLC. The output shaft of the second motor 8 is fixedly connected to one side of the clamping arm 6. The two clamping arms 6 are driven to rotate by the second motor 8. A transmission rod 12 is fixedly installed between the clamping arms 6 located on the left and right sides at the lower end of the fixed beam 1. The two clamping arms 6 are driven by the transmission rod 12 between them, so that the clamping arms 6 on both sides move synchronously. The two clamping arms 6 move inward towards each other to clamp both sides of the large-sized goods, thereby improving the stability of the goods. By setting two groups of fixing mechanisms, on the one hand, the stability is improved, and on the other hand, the steps of installing fixing ropes are reduced, greatly improving the loading and unloading efficiency;

[0029] A moving plate 9 is slidably connected to the upper surface of the fixed beam 1. A lifting ring 11 is fixedly installed on the top of the moving plate 9. The loading and unloading device is connected to the bridge transportation equipment through the lifting ring 11. A cylinder 10 is hinged to one side of the upper surface of the fixed beam 1. The output shaft of the cylinder 10 is hinged to the outer wall of one side of the moving plate 9. When unloading is required, the cylinder 10 contracts to drive the moving plate 9 to move to the right along the fixed beam 1. At this time, the center of gravity of the loading and unloading device shifts and tilts towards one side, so as to facilitate the unloading of the goods.

[0030] Working principle:

[0031] When loading large-sized goods, first move the fixed beam 1 to the upper end of the large-sized goods. The first motor 3 rotates clockwise to drive the fixed frame 2 to open outwards. Move the large-sized goods between the two fixed frames 2. The first motor 3 rotates counterclockwise to move the two fixed frames 2 inwards to place the large-sized goods between the two fixed frames 2 to complete the preliminary fixation. At this time, the two clamping arms 6 move inward towards each other to clamp both sides of the large-sized goods, thereby improving the stability of the goods. By setting two groups of fixing mechanisms, on the one hand, the stability is improved, and on the other hand, the steps of installing fixing ropes are reduced, greatly improving the loading and unloading efficiency.
