Abstract
The invention relates to a portable crane which comprises an underframe, brackets and a motor. The underframe is of a quadrilateral frame structure; the brackets are arranged at both symmetrical edges of the underframe; the brackets are of a triangular structure; the bottom edges of the brackets are respectively welded at the endpoints of both the symmetrical edges of the underframe; a rotating shaft is arranged at the top ends of the two brackets; the motors are arranged outside the top ends of the brackets; the rotating shaft is connected with the motors; a pulling rope is wound on the rotating shaft; the bottom end of the pulling rope is connected with a mounting bracket; and a roller is movably arranged below each corner of the underframe. The portable crane has the advantages of reasonable design, small size, convenience and practicality and the like.
Description
Technical fieldThe present invention relates to a kind of transportation means, especially a kind of weight-lifting equipment.
Background technologyAs everyone knows, hoisting crane is one of jacking equipment the most frequently used in the building operation.But, for the dell operation, lack at present a kind of special weight-lifting equipment.In addition, the most volume of present hoisting crane is larger, and quality is larger, can only haul and use by locomotive, is not suitable for promoting the use of at home.
Summary of the inventionThe purpose of this invention is to provide little, easy and simple to handle, the mobile easily portable crane of a kind of volume.
The present invention includes underframe, support and motor, described underframe is the quadrilateral frame shelf structure, and symmetrical both sides are provided with support, and support is triangular structure, and the base of support is welded on respectively the end points place on the symmetrical both sides of underframe; Rotating shaft is installed on top at two supports, the outside mounted motor of cantilever tip, and rotating shaft is connected with motor; Twine hauling rope in rotating shaft, the hauling rope bottom connects carriage; Each corner underside at underframe is installed roller.
When mobile, the user puts down roller from the side of each corner of underframe, so that roller contacts to earth, can promote on the ground this device this moment, saves carrying muscle power and time.During work, with the side of roller striking to underframe, underframe is contacted to earth, and underframe is covered the hole in the ground buckle, underframe provides stable supporting role, then carriage is put into the hole in the ground, during lifting, the user can closed motor switch, transfers by motor positive and negative to drive rotating shaft and rotate, by rotating shaft hauling rope is put down or is wrapped in the rotating shaft, thereby realize the lifting purpose.
Compared with the prior art, beneficial effect of the present invention is: reasonable in design, volume is little, convenient and practical, be convenient to mobile, the lifting work condition that facilitates.
Description of drawingsFig. 1 is spatial structure sketch of the present invention.
Drawing reference numeral: 1 is that underframe, 2 is that support, 3 is that motor, 4 is that rotating shaft, 5 is that hauling rope, 6 is that carriage, 7 is roller.
The specific embodimentIn spatial structure sketch of the present invention shown in Figure 1, comprise underframe 1, support 2 and motor 3, described underframe is the quadrilateral frame shelf structure, and symmetrical both sides are provided with support, support is triangular structure, and the base of support is welded on respectively the end points place on the symmetrical both sides of underframe; Rotating shaft 4 is installed on top at two supports, the outside mounted motor of cantilever tip, and rotating shaft is connected with motor; Twine hauling rope 5 in rotating shaft, the hauling rope bottom connects carriage 6; Each corner underside at underframe is installed roller 7.
