The utility model is described in detail with reference to the accompanying drawings, as shown in fig. 1-6, a galvanized pipe stacking and hoisting device comprises a bearing plate 1, two rectangular pipes 2 are hinged on the bearing plate 1, a first U-shaped guide rail 3 and a second U-shaped guide rail 4 are arranged in the two rectangular pipes 2, a driving lifting plate 5 is connected in the first U-shaped guide rail 3 in a sliding manner, a driven lifting plate 6 is connected in the second U-shaped guide rail 4 in a sliding manner, a gear 7 is arranged between the driving lifting plate 5 and the driven lifting plate 6, the gear 7 is rotatably arranged in the rectangular pipes 2 through a first rotating shaft 8, a first rack 9 meshed with the gear 7 is arranged on the driving lifting plate 5, a second rack 10 meshed with the gear 7 is arranged on the driven lifting plate 6, a first limiting plate 11 is fixed at the top end of the driving lifting plate 5, be fixed with lug 12 on the first limiting plate 11, second U type guide rail 4 below is equipped with second limiting plate 13, two all open on the rectangular pipe 2 has bar opening 14, one of them be fixed with the articulated shaft 15 that stretches out bar opening 14 on the driven lifter plate 6 in the rectangular pipe 2, the articulated shaft 15 stretches out the one end of bar opening 14 and articulates there is depression bar 16, another be fixed with the flange bearing 17 that stretches out bar opening 14 on the driven lifter plate 6 in the rectangular pipe 2, install second pivot 18 in the flange bearing 17, the 18 other ends of second pivot are fixed with joint 19, the 16 other ends of depression bar can be with the joint of joint 19.

Inclined supporting rods 20 are hinged to the end faces, back to each other, of the two rectangular tubes 2.

Both sides of the upper end of the bearing plate 1 are provided with a plurality of protruding parts 21 matched with the inclined stay bars 20, and the protruding parts 21 on the same side are regularly arranged.

The working principle of the embodiment is as follows: when the device is used, at least two devices are arranged on a plane, the inclination angle of the rectangular pipe 2 is adjusted firstly, the lower end of the inclined support rod 20 is clamped between the convex parts 21, the rectangular pipe 2 can be fixed, then the galvanized pipe is stacked on the bearing plate 1, the balance of two ends of the galvanized pipe is ensured, after the galvanized pipe is placed, one end of the pressure rod 16 is moved into the clamping piece 19, and the connecting end of the pressure rod 16 and the articulated shaft 15 can transversely move for a small distance on the articulated shaft 15, so that the pressure rod 16 can be moved into the clamping piece 19; then, a hoisting machine is used for hoisting the device and the galvanized pipe through a lifting lug 12, the lifting lug 12 is lifted at first, the lifting lug 12 drives a driving lifting plate 5 to lift, the driving lifting plate 5 is lifted stably in a first U-shaped guide rail 3, a first rack 9 is lifted along with the driving lifting plate 5, the first rack 9 drives a gear 7 to rotate, the gear 7 drives a second rack 10 to descend, a driven lifting plate 6 descends along with a second rack 10 in a second U-shaped guide rail 4, the driven lifting plate 6 in the left rectangular pipe 2 drives a hinge shaft 15 and a pressure lever 16 to descend, the driven lifting plate 6 in the right rectangular pipe 2 drives a flange bearing 17, a second rotating shaft 18, a clamping piece 19 and the pressure lever 16 to descend, and therefore the pressure lever 16 presses the galvanized pipe;

in the hoisting process, the inclination angle of the rectangular pipe 2 is changed, one end of a pressure lever 16 is hinged with a hinged shaft 15 by a rotatable angle, the other end of the pressure lever 16 is clamped in a clamping piece 19 and can move in the clamping piece 19 in a telescopic way, the clamping piece 19 is connected with a second rotating shaft 18 arranged in a flange bearing 17, so that when the inclination angle of the rectangular pipe 2 is changed, the pressure lever 16 can always horizontally press down the galvanized pipe, when a driven lifting plate 6 descends to be in contact with a second limiting plate 13, the pressure lever 16 is clamped, at the moment, the pressure lever 16 descends to the lowest position away from a bearing plate 1, and a driving lifting plate 5 stretches out to the maximum length from the inside of the rectangular pipe 2;

after the hoist and mount are accomplished, diagonal brace 20 still blocks in bellying 21 department thereby make rectangular pipe 2 remain stable, the device can regard as galvanized pipe piler to use this moment, when needing to take out galvanized pipe, manual lug 12 that pushes down, make initiative lifter plate 5 descend, thereby drive driven lifter plate 6, the depression bar 16 rises, make depression bar 16 no longer compress tightly galvanized pipe, just can block when first limiting plate 11 descends to contact with rectangular pipe 2 top, prevent that initiative lifter plate 5 and lug 12 from weighing down in rectangular pipe 2, when needing to take away galvanized pipe, can shift out joint piece 19 with depression bar 16, rotate depression bar 16 to the galvanized pipe outside afterwards, can take out galvanized pipe.

Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
