It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The invention provides an automatic unloading device for a wave beam guardrail plate, which comprises a lifting structure, a jacking structure and a hook positioning structure arranged on the lifting structure.
Referring to fig. 1, the landing gear structure comprises a landing gear 1, the bottom of the landing gear 1 is hinged on a workbench 11, one side of the landing gear 1 is connected with a landing driving member 12, and in the invention, the landing driving member 12 is an oil cylinder. By means of the landing gear drive 12, the landing gear 1 is allowed to fall and be vertically upwards, with the landing gear 1 being perpendicular to the table 11.
The jacking structure comprises a jacking driving piece 2 arranged on a workbench 11, wherein the top of the jacking driving piece 2 is connected with a jacking plate 21, and the jacking plate 21 is movably abutted against the bottom of the corrugated plate 4. In the present invention, the jack-up driving member 2 is an air cylinder.
Referring to fig. 1 and 2, the hook positioning structure comprises a positioning frame 3 fixed at the top of the landing gear 1, wherein inclined plates 31 are respectively fixed at two side edges of the positioning frame 3, the outer surface of each inclined plate 31 is provided with a friction layer, and each inclined plate 31 faces to the landing gear 1; an elastic member 32 is connected between the opening end of the sloping plate 31 and the positioning frame 3, and in the present invention, the elastic member 32 is a pressure spring. Referring to fig. 2, in the present invention, the included angle a between the inclined plate 31 and the positioning frame 3 is in the range of 10-40 degrees.
Referring to fig. 1, a hanging hole 41 is formed at the top of the corrugated plate 4, the bottom end of the hook 5 is hung on the hanging hole 41, and the top of the hook 5 is hung on a hanging piece 51; the two sloping plates 31 are movably clamped into the gap between the two hooks 5, and the distance between the opening ends of the two sloping plates 31 is larger than the distance between the two hooks 5 (in the invention, the distance between the two hooks 5 is constant). After the corrugated plate is sprayed, the corrugated plate is freely hung at the bottom end of the hook 5 and is in a vertical state.
When the landing gear 1 is not in work, the landing gear is in a lodging state, and when the corrugated plate 4 needs to be unhooked, the corrugated plate 4 is vertical through the function of the landing driving piece 12; in the process that the corrugated plate 4 is changed from a lodging state to a vertical state, the hook positioning structure moves along the direction B in fig. 2, the two inclined plates 31 are gradually clamped between the two hooks 5, and as the outer surfaces of the inclined plates 31 are provided with friction layers, the two inclined plates 31 support or support the hooks 5 between the two hooks 5 under the action of friction force, and meanwhile, the position of the suspension piece 51 is not moved, and the hooks 5 are positioned under the combined action of the suspension piece 51 and the hooks 5; at this time, the jacking driving member 2 is started, the jacking plate 21 jacks up the corrugated plate 4, the corrugated plate 4 moves upward, but the position of the hook 5 is not moved, and the bottom of the hook 5 can be automatically separated from the hanging hole 41 of the corrugated plate 4, so that unhooking of the corrugated plate 4 is realized. After unhooking, the landing gear 1 changes from a vertical state to a lodging state, and the corrugated plate 4 is laid on the landing gear 1 and lodged together with the landing gear 1.
In the present invention, the upward jacking force of the jacking plate 21 is not greater than the frictional force between the sloping plate 31 and the hooks 5, i.e., the jacking plate 21 is capable of jacking up the corrugated plate 4 but is incapable of jacking up the hooks 5.
Preferably, the workbench 11 is further provided with a centralizing structure, the centralizing structure comprises a centralizing driving piece 6 fixedly connected to the workbench 11 through a centralizing rod 64, the centralizing driving piece 6 is connected with a centralizing plate 61, two ends of the centralizing plate 61 are fixedly connected with connecting plates 62, a centralizing roller 63 is rotatably connected between the two connecting plates 62, and the centralizing roller 63 is movably abutted against the corrugated plate 4. After the corrugated plate 4 finishes unhooking, in order to prevent the corrugated plate 4 from falling down together with the landing gear 1, a righting structure is arranged; when the jack-up driving member 2 is started and the righting driving member 6 is started at the same time, when the corrugated plate 4 is jacked up, the righting roller 63 abuts against the corrugated plate 4 and pushes the corrugated plate 4 to one side of the landing gear 1. Referring to fig. 3, it is preferable that the diameter of the righting roller 63 is larger than the width of the connection plate 62 so that the righting roller 63 abuts against the corrugated plate 4 without the connection plate 62 contacting the corrugated plate 4, and the righting roller 63 rolls with the upward movement of the corrugated plate 4 without damaging the sprayed layer on the surface of the corrugated plate 4. In the present invention, the righting driver 6 is a cylinder.
Preferably, the cross beam of the landing gear 1 is also provided with two baffles 13, and a corrugated plate 4 is arranged between the two baffles 13; in order to prevent the corrugated plate 4 from moving to two sides in the process of falling along with the landing gear 1 after the corrugated plate 4 is unhooked, the corrugated plate 4 is limited by the two baffles 13.
Preferably, the automatic unloading device further comprises a retaining plate 14 arranged at the bottom of the corrugated plate 4 and close to the landing gear 1; after the corrugated plate 4 is jacked up and unhooked, the jacking plate 21 descends, so that the corrugated plate 4 automatically falls under the action of gravity, and the bottom of the corrugated plate 4 is abutted against the abutment plate 14 by arranging the abutment plate 14 and falls along with the landing gear 1. In the present invention, at least two retaining plates 14 are disposed on two sides of the jacking plate 21, so that the jacking plate 21 and the retaining plates 14 are interfered with each other complementarily. In the invention, the bearing plate 14 is fixedly sleeved on the rotating shaft 141, the rotating shaft 141 is rotatably connected to the landing gear 1, one end of the rotating shaft 141 penetrates out of the landing gear 1 and then is connected with the rotating driving piece 142, and in the invention, the rotating driving piece 142 is a motor; by the action of the rotation driving piece 142, the retaining plate 14 can rotate, when the corrugated plate 4 is about to fall, the retaining plate 14 is enabled to be horizontal and fully abutted against the corrugated plate 4, and when unhooking work is not needed, the retaining plate 14 is arranged vertically.
In summary, the invention sets the hook positioning structure and the jacking structure to generate friction force between the hook and the inclined plates, limits the position of the hook through the friction force effect and the supporting effect of the two inclined plates on the hook, and the jacking structure jacks up from the bottom of the corrugated plate, and the force of the jacking structure is smaller than the friction force between the hook and the inclined plates, so that the jacking structure can jack up the corrugated plate and can not jack up the hook, and the hook is separated from the hanging hole of the corrugated plate, thereby achieving the purpose of unhooking; the corrugated plate after unhooking is fallen down to one side along with the lifting structure. In summary, the beneficial effects of the invention are as follows: the automatic unhooking device has the advantages of being simple in structure, realizing mechanization and automation unhooking of the corrugated plate, completing workpiece discharging work of the corrugated plate, reducing labor intensity, improving working efficiency, saving labor cost and being very suitable for batch production of large-scale processing enterprises.
Of course, the present invention is capable of other various embodiments and its several details are capable of modification and variation in light of the present invention, as will be apparent to those skilled in the art, without departing from the spirit and scope of the invention as defined in the appended claims.
