Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides an ultra-large protective portal crane, including girder 1, landing leg 2, hoisting motor 3, lifting rope 4 and lifting hook 7, two sets of landing legs 2 that are the symmetric distribution are installed to girder 1's lower extreme, girder 1's lower extreme is located two sets of landing leg 2's inboard sliding connection has two sets of hoisting motor 3, hoisting motor 3's lower part has tied up lifting rope 4, the free end of lifting rope 4 has tied up pulley 5, link plate 6 is installed at pulley 5's both ends, lifting hook 7 is installed to link plate 6's lower part, axle sleeve 8 is installed to link plate 6's outer end, pulley 5, link plate 6 and axle sleeve 8's inside is inlayed and is equipped with axostylus axostyle 11, axostylus.

Specifically, as shown in fig. 1 and 2, the outside of landing leg 2 has been seted up spout 13, and the both ends fixedly connected with slider 12 of axostylus axostyle 11, slider 12 cunning are laminated in the inside of spout 13, and the inner wall of slider 12 is laminated with spout 13's surface mutually to restriction axostylus axostyle 11 rocks about the lift in-process.

Specifically, as shown in fig. 3 and 4, pull rod 9 is installed to the upper end of axle sleeve 8, the internally mounted of axle sleeve 8 has spacing 10, through pull rod 9 person of facilitating the use to axle sleeve 8's rotation, the width of spacing 10 slightly is less than the width of the recess of seting up in axostylus axostyle 11, when spacing 10 is located the upside of axostylus axostyle 11, axostylus axostyle 11 is laminated with axle sleeve 8's smooth surface under the action of gravity mutually, axle sleeve 8 can slide along axostylus axostyle 11 this moment, when spacing 10 is located the downside of axostylus axostyle 11, under the action of gravity, the groove part and the spacing 10 block of axost.

The working principle is as follows: when the protective gantry crane is used, firstly, a user needs to hang a heavy object on the lifting hook 7 and control the hoisting motor 3, the heavy object is pulled to move upwards through the lifting rope 4, so that the shaft rod 11 embedded in the pulley 5, the hanging plate 6 and the shaft sleeve 8 rises together, at the moment, the sliding blocks 12 at two ends of the shaft rod 11 can move upwards along the sliding grooves 13 in the supporting legs 2, due to the structural design, when the crane lifts the goods, the lifting rope 4 on the crane cannot be influenced by wind power to drive the goods to shake around, a certain protective effect is achieved on the lifting of the goods, the protective gantry crane can not be influenced by the wind power, and therefore the stability of the lifted goods is improved, secondly, the user can change the position of the limiting strips 10 in the shaft sleeve 8 by rotating the pull rod 9 on the shaft sleeve 8, when the shaft sleeve 8 is rotated, and the limiting strips 10 are positioned above the shaft rod 11, can slide link plate 6 and lifting hook 7 along axostylus axostyle 11, the user can be according to the size of a dimension of goods, change the interval of two sets of lifting hooks 7, rotate axle sleeve 8, when making spacing 10 be located axostylus axostyle 11's below, through the gravity auto-lock, spacing 10 can block in the recess of seting up in axle sleeve 8, thereby restriction link plate 6 and lifting hook 7's slip, realized that this protective door formula hoist can change the interval of lifting hook 7, lift by crane the goods of different specifications, and the rigidity of in-process lifting hook 7 on axostylus axostyle 11 lifted by crane, thereby further improved the effect of the protection stability of device.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
