The bottom surface, one end of described crawl plate is fixed with vertical adjustable plate, the middle part of vertical adjustable plate has vertical through hole, proximity switch sleeve is in vertical through hole, the head place of proximity switch has and radially extends limit, the tail end place of proximity switch is bolted with nut, and vertical adjustable plate is clamped in and radially extends between limit and nut.
Described governor motion includes two and regulates plate body, two regulate plate body and are fixed on below the one end capturing plate, the two ends of adjusting screw rod are hinged on two and regulate on plate body, the adjustment plate body in outside is fixed with adjustment motor, the output shaft regulating motor is splined shaft, and the output shaft regulating motor stretches in the splined hole that the outer end of adjusting screw rod has, and regulates block and is screwed onto in adjusting screw rod, being fixed with buffering block on two adjustment plate bodys, buffering block is corresponding with regulating block.
The end face of described movable stand has the contiguous block portion raised up.
The bottom surface, middle part of described extension board has crashproof elastomer block, and crashproof elastomer block is in the surface capturing plate.
The beneficial effects of the utility model are in that:
Shaped steel can quickly be clamped by it, its firm grip, it is not easy to make shaped steel drop.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation between adjustment block of the present utility model and grip block.
Detailed description of the invention:
Embodiment: see shown in Fig. 1 to Fig. 2, a kind of shaped steel clamps hoisting mechanism automatically, and it includes movable stand 50, the front portion of described movable stand 50 has extension board 53, the end face of extension board 53 is fixed with at least two and promotes oil cylinder 54, the push rod promoting oil cylinder 54 extends through plate 53 straight down and is fixed on crawl plate 55, the two ends, bottom surface capturing plate 55 are respectively and fixedly provided with governor motion 60, governor motion 60 is fixed with adjustment block 61, two adjustment block 61 opposite faces are respectively and fixedly provided with two clamp standoff plates 62, clamp standoff plate 62 is fixed with clamping oil cylinder 63, the push rod of clamping oil cylinder 63 through clamp standoff plate 62 and is fixed with grip block 64, the grip block 64 being fixed with on the push rod of two relative clamping oil cylinders 63 is corresponding,
The bottom surface, one end of described crawl plate 55 is fixed with vertical adjustable plate 68, the middle part of vertical adjustable plate 68 has vertical through hole 69, proximity switch 70 sleeve is in vertical through hole 69, the head place of proximity switch 70 has and radially extends limit 71, the tail end place of proximity switch 70 is bolted with nut 72, and vertical adjustable plate 68 is clamped in and radially extends between limit 71 and nut 72.
Further, described governor motion 60 includes two and regulates plate body 65, two regulate plate body 65 and are fixed on below the one end capturing plate 55, the two ends of adjusting screw rod 66 are hinged on two and regulate on plate body 65, the adjustment plate body 65 in outside is fixed with adjustment motor 67, the output shaft regulating motor 67 is splined shaft, the output shaft regulating motor 67 stretches in the splined hole that the outer end of adjusting screw rod 66 has, regulate block 61 and be screwed onto in adjusting screw rod 66, being fixed with buffering block 671 on two adjustment plate bodys 65, buffering block 671 is corresponding with regulating block 61.
Further, the end face of described movable stand 50 has the contiguous block portion 52 raised up.
Further, the bottom surface, middle part of described extension board 53 has crashproof elastomer block 1, and crashproof elastomer block 1 is in the surface capturing plate 55.
Operation principle: the contiguous block portion 52 of the present embodiment is screwed onto on drive screw, contiguous block portion 52 can be realized mobile when drive screw is rotated, and press under the push rod of oil cylinder 54 by promoting, make to capture the top (shaped steel adopted in the present embodiment is I-steel) that plate 55 declines and is in shaped steel, then, regulate motor 67 to run, adjusting screw rod 66 is rotated, two are made to regulate block 61 near the two ends of shaped steel, the push rod then passing through clamping oil cylinder 63 promotes, shaped steel is clamped by two grip blocks 64, then, promote the push rod retraction of oil cylinder 54,
Then, run by drive motor 43, so that drive screw 41 rotates so that movable stand 50 moves, thus shaped steel is carried, after being transported to required cartage department, the push rod of oil cylinder 54 is promoted to decline so that shaped steel is in ground, simultaneously, the push rod retraction of clamping oil cylinder 63, thus makes shaped steel be positioned over ground, completes carrying.
And proximity switch 70 is used for limiting crawl plate 55 hoisting depth, it is prevented that capture plate 55 and promote too high close with extension board 53.
Embodiment of above is merely to illustrate this utility model; and be not limitation of the utility model; those of ordinary skill about technical field; when without departing from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all equivalent technical schemes fall within category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
