Abstract
The utility model discloses a cantilever crane, which comprises a fixed shaft (1); an upper pressing plate (2) and a lower bearing plate (3) are respectively arranged at the upper part and the lower part of the fixed shaft (1); two ends of the fixed shaft (1) respectively penetrate through the upper pressing plate (2) and the lower bearing plate (3); a rotary drum (4) located between the upper pressing plate (2) and the lower bearing plate (3) and connected with a cantilever is arranged on an outer arm of the fixed shaft (1); and a friction rotating device is arranged between the fixed shaft (1) and the rotary drum (4), the upper pressing plate (2) and the lower bearing plate (3). The cantilever crane has the advantages of adopting simple structure, being flexible to rotate and being convenient to use and operate; through using the cantilever crane, friction and wear between the fixed shaft and the rotary drum, the upper pressing plate and the lower bearing plate are greatly reduced and the service life of the cantilever crane is prolonged.
Description
Technical field
The utility model relates to a kind of hanging apparatus, and particularly a kind of cantilever hangs.
Background technology
At present, the cantilever of industrial normal use hangs and includes anchor shaft, be respectively arranged with top board and lower support plate in the anchor shaft upper and lower, the two ends of described anchor shaft are passed top board and lower support plate respectively, described anchor shaft outer wall is provided with between top board and lower support plate, and with cantilever bonded assembly rotating cylinder, the left-right rotation of cantilever is exactly (as the Fig. 1) that realizes by rotating cylinder, wherein, anchor shaft and rotating cylinder, top board, rotation between the lower support plate is the running of sliding, and is the direct friction contact between them, mutual in the course of the work friction force is bigger, resistance is bigger in the rotation process, rotate dumb, effort during operation; Sharply rise owing to the frictional heating temperature between anchor shaft and rotating cylinder, top board, the lower support plate, and direct friction contacts between anchor shaft and rotating cylinder, top board, the lower support plate, cause anchor shaft, rotating cylinder, top board and lower support plate wearing and tearing to be accelerated, well damage has shortened the service life that cantilever hangs.
The utility model content
The purpose of this utility model is hung with regard to providing a kind of cantilever that reduces friction force between anchor shaft and rotating cylinder, top board, the lower support plate.
The purpose of this utility model is to realize by such technical scheme, a kind of cantilever hangs, include anchor shaft, be respectively arranged with top board and lower support plate in the anchor shaft upper and lower, the two ends of described anchor shaft are passed top board and lower support plate respectively, described anchor shaft outer wall is provided with between top board and lower support plate, and with cantilever bonded assembly rotating cylinder, describedly between anchor shaft and rotating cylinder, top board, lower support plate, be provided with the frictional rotation device.
Further, described wheel word is the bearing that is separately positioned on the anchor shaft upper and lower, and a described end face that is arranged on the bearing on anchor shaft top contacts with top board, and a described end face that is arranged on the bearing of anchor shaft bottom contacts with lower support plate.
Wherein, the described bearing that is arranged on the anchor shaft bottom is two, one one is the radial bearing A between anchor shaft and rotating cylinder in order to be positioned at the one direction thrust bearing A of lower support plate, and the upper surface of described one direction thrust bearing A contacts with the lower surface of radial bearing A.
In order to reduce the friction force between anchor shaft top and the rotating cylinder, the described bearing that is arranged on anchor shaft top is radial bearing B, and described radial bearing B is between anchor shaft and rotating cylinder.
In order to reduce the friction force between anchor shaft top and the top board, described anchor shaft top also is provided with one direction thrust bearing B, and described one direction thrust bearing B is positioned at top board, and its lower surface contacts with the upper surface of radial bearing B.
Owing to adopted technique scheme, the utlity model has advantage simple in structure, that rotation is flexible, use is easy to operate, use it to significantly reduce friction force between anchor shaft and rotating cylinder, top board, the lower support plate, reduce the wearing and tearing between anchor shaft and rotating cylinder, top board, the lower support plate, prolonged the service life that cantilever hangs.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 hangs structural representation for original cantilever;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Embodiment 1: as shown in Figure 2, a kind of cantilever hangs, include anchor shaft 1, be respectively arranged with top board 2 and lower support plate 3 in anchor shaft 1 upper and lower, the two ends of described anchor shaft 1 are passed top board 2 and lower support plate 3 respectively, described anchor shaft 1 outer wall is provided with between top board 2 and lower support plate 3, and with cantilever bonded assembly rotating cylinder 4, describedly between anchor shaft 1 and rotating cylinder 4, top board 2, lower support plate 3, be provided with the frictional rotation device.
Described wheel word is the bearing that is separately positioned on anchor shaft 1 upper and lower, and a described end face that is arranged on the bearing on anchor shaft 1 top contacts with top board 2, and a described end face that is arranged on the bearing of anchor shaft 1 bottom contacts with lower support plate 3.
The described bearing that is arranged on anchor shaft 1 bottom is two, one for being positioned at the one direction thrust bearing A5 of lower support plate 3, one is the radial bearing A6 between anchor shaft 1 and rotating cylinder 4, and the upper surface of described one direction thrust bearing A5 contacts with the lower surface of radial bearing A6.
The described bearing that is arranged on anchor shaft 1 top is radial bearing B7, and described radial bearing B7 is between anchor shaft 1 and rotating cylinder 4; Described anchor shaft 1 top also is provided with one direction thrust bearing B8, and described one direction thrust bearing B8 is positioned at top board 2, and its lower surface contacts with the upper surface of radial bearing B7.
Do the friction force that makes between anchor shaft 1 and rotating cylinder 4, top board 2, the lower support plate 3 like this and become friction of rolling by sliding motion, reduced the friction force between them, not wearing and tearing between anchor shaft 1 and rotating cylinder 4, top board 2, the lower support plate 3, and rotate flexibly, the operator is laborsaving to save time, and has improved service life.
