Detailed Implementation
[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] like Figures 1 to 7 As shown, a typical embodiment of this utility model provides a short-distance rebar side-tilting and automatic unloading device, including a frame 1 and a side-tilting frame 2. One side of the side-tilting frame 2 is rotatably connected to the frame 1 for loading rebar. A lifting cylinder 3 for driving the side-tilting frame 2 to tilt laterally is installed on the frame 1. Wheels are provided at the bottom of the frame 1.
[0025] In application, the steel bar transport and automatic unloading device is mounted on a tractor. The rolling of the wheels allows the frame 1 to carry the side tilting frame 2. During the transport of steel bars, the steel bars are placed directly on the side tilting frame 2. After the steel bars are transported to the designated location, the lifting cylinder 3 is activated. The lifting cylinder 3 causes the side tilting frame 2 to tilt to one side of the frame 1, thus realizing the unloading operation of the steel bars from the side.
[0026] Specifically, the side-tilting frame 2 has spaced loading slots 4 in the middle to prevent ring-shaped reinforcing bars from rolling. Straight reinforcing bars are placed on both sides of the loading slots 4. The wheels are positioned between adjacent loading slots 4 along the length of the frame 1. By using the loading slots 4, when a ring-shaped reinforcing bar is placed on the side-tilting frame 2, the bottom end of the ring-shaped reinforcing bar is located within the loading slot 4, preventing it from rolling and improving the safety and stability of the reinforcing bar transport. Simultaneously, the straight reinforcing bars placed on both sides of the ring-shaped reinforcing bar further limit and block its movement, further enhancing safety and stability.
[0027] The loading slot 4 is formed by two longitudinal side plates 5 distributed parallel to the length of the frame 1 and two lateral side plates 6 distributed parallel to the width of the frame 1. The two lateral side plates 6 are connected by a sliding plate 7 at the same side ends, and the sliding plate 7 is in sliding engagement with the longitudinal side plates 5.
[0028] The sliding plate 7 can drive the long side plate 5 and the wide side plate 6 to move to one side in the width direction of the frame 1. When the side tilting frame 2 is tilted upward to the tilted state for steel bar unloading, the sliding plate 7 drives the long side plate 5 and the wide side plate 6 to move to the lower end of the side tilting frame 2. This can carry the ring steel bar closer to the ground, reduce the falling height of the ring steel bar during unloading, reduce the impact of the ring steel bar, effectively prevent steel bar deformation and damage, and further improve the safety of steel bar unloading.
[0029] Specifically, a rotatable lead screw 8 is provided inside the longitudinal side plate 5. A threaded sleeve 9 is fitted on the external thread of the lead screw 8. The threaded sleeve 9 is fixedly connected to the sliding plate 7. A power motor 10 is connected to one end of the lead screw 8. The power motor 10 is installed at one end of the longitudinal side plate 5.
[0030] In a relatively specific embodiment, a slider is fixedly provided on one side of the sliding plate 7. The slider and the sliding plate 7 form an "H" shaped structure. A through groove is provided on the side of the longitudinal side plate 5. The upper and lower slots between the sliding plate 7 and the slider are respectively fitted on the upper and lower ends of the through groove. The through groove and the slider enable the sliding plate 7 to be stably slidably installed on the longitudinal side plate 5.
[0031] When the side-tilting frame 2 is tilted to the rebar unloading state, the power motor 10 is started. The power motor 10 drives the lead screw 8 to rotate. The lead screw 8 drives the sliding plate 7 to move through the lead sleeve 9. Then, the sliding plate 7 drives the long side plate 5 and the wide side plate 6 to move, so as to transport the ring rebar towards the ground.
[0032] The end of the sliding plate 7 away from the flipping direction of the side-tilting frame 2 extends outward to form an extension 11, and the threaded sleeve 9 is fixedly installed on the extension 11. By setting the extension 11, the distance that the long side plate 5 and the wide side plate 6 are displaced to the ground can be extended, so that the ring-shaped steel bar can be transported to a state close to the ground, thereby minimizing the height difference between the ring-shaped steel bar and the ground when unloading and improving the protection performance of the steel bar.
[0033] A side extension frame 12 that can extend outward is provided on the outer side of the wide side plate 6 facing the flipping direction of the side-flipping frame 2, so that the side-flipping frame 2 can contact the ground after flipping. By setting the side extension frame 12 to contact the ground, the ring-shaped steel bar can roll along the side extension frame 12 to the ground, preventing the ring-shaped steel bar from falling and causing a large impact, and further improving the protection performance of the steel bar.
[0034] In this embodiment, when the sliding plate 7 drives the long side plate 5 and the wide side plate 6 to move towards the ground, the side extension frame 12 first contacts the ground. During the subsequent displacement of the sliding plate 7, the side extension frame 12 maintains the state of contacting the ground at its outer end and moves relative to the wide side plate 6. At this time, the wide side plate 6 is in a state of continuously approaching the side extension frame 12.
[0035] The inner side of the side extension frame 12 is provided with two through rods 13 that pass through the adjacent wide side plate 6. A synchronizing rod 14 is provided between the inner ends of the two through rods 13, which is used to push out the annular steel bar by moving towards the middle of the two wide side plates 6 of the loading groove 4.
[0036] This configuration allows the annular steel bar to be automatically pushed out from between the two wide side plates 6 after the side extension frame 12 contacts the ground, thus achieving automatic unloading of the annular steel bar and making it easier to unload the steel bar.
[0037] The inner end of the through rod 13 is rotatably mounted on the bottom of the synchronizing rod 14, and the outer end of the through rod 13 is fixedly connected to a stop arm 15. When the through rod 13 moves inward, it drives the stop arm 15 to switch from a vertical state to a horizontal state. By setting the stop arm 15, the stop arm 15 can prevent further restriction of the steel bars during the process of transporting the steel bars, thereby improving the stability of the steel bar transport.
[0038] When the steel bars are unloaded, when the side tilting frame 2 is tilted to the tilted state, the stop arm 15 can prevent the steel bars from sliding directly off the side tilting frame 2, thus achieving stable support for the steel bars.
[0039] When the power motor 10 is started, during the process of the sliding plate 7 driving the two wide side plates 6 to move towards the ground, both the ring steel bars and the straight steel bars are carried and moved towards the ground.
[0040] After the outer end of the side extension frame 12 contacts the ground, as the sliding plate 7 continues to move, the through rod 13 will move inward relative to the wide side plate 6. During this process, the synchronous rod 14 will move from the side of the bottom of the annular rebar to its bottom position and lift the annular rebar, so that the annular rebar can be effectively detached. At the same time, the straight groove 17 and the spiral groove 16 completely pass through the guide block 19. During the process of the spiral groove 16 passing through the guide block 19, the through rod 13 rotates 90° and drives the stop arm 15 to rotate to the lateral position.
[0041] At this point, the stop arm 15 is retracted within the side extension frame 12, and its obstruction of the reinforcing bars is removed. The reinforcing bars will then slide down from the top of the side extension frame 12 to the ground. In this embodiment, the impact on the reinforcing bars during their descent is greatly reduced, better protecting all the reinforcing bars and improving the safety and stability of unloading them.
[0042] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
