Abstract
The utility model discloses an electric single beam crane comprising a main beam (1), an electric gourd (2) and a sliding contact line mechanism used for hanging a cable (3), the bottom plate (7) of the main beam (1) is provided with a track that is applicable to the walking wheel (9) of the electric gourd (2) walking on. The utility model is characterized in that the two sides of the main beam (1) are respectively matched with at least one horizontal wheel (10) taken the side wall of the main beam (1) as the moving track, and the rotating axis (11) of the horizontal wheel (10) are fixedly connected with the electric gourd (2); Besides, the walking wheel (9) of the electric gourd (2) is a column shape and the track face matching with the walking wheel (9) is a horizontal flat surface. The utility model has advantages of perfect running stability, high security, large rising height, simple producing technique and material saving, which is applicable to the electric single beam and door crane.
Description
Technical field
The utility model relates to the technical field of mono beam overhead crane.
Background technology
Existing mono beam overhead crane, described in Chinese patent application 90205632.0 disclosed " mono beam overhead crane " and Chinese patent 93226708.4 disclosed " mono beam overhead crane box girder ", all be respectively to be provided with track in the both sides of kingpost baseplate, electric block orbits by its road wheel.For guaranteeing electric block walking smoothly in orbit, must leave certain interval between the end face of road wheel and the girder sidewall, in case hinder the trouble-free operation of electric block between road wheel and the girder sidewall because of contact friction, influence the stability of electric block walking, but owing to rocking of hoisting crane lifted weight, very easily cause the side travel of electric block and the end face of road wheel is contacted with the girder sidewall, therefore the orbital plane on the kingpost baseplate all is arranged to have certain slope, correspondingly, the road wheel of electric block all is designed to the bevel wheel that adapts with it, though increased the difficulty of electric block side travel like this, but still can not fundamentally deal with problems fully, such design has simultaneously also brought new defective and potential safety hazard for hoisting crane, because the conical design of design of the gradient of orbital plane and road wheel, make road wheel be subjected to thrust to the girder outside, and this thrust increases with the increase of hoisting crane lifted weight weight, cause the distortion of electric block region of interest and distance is changed easily like this, directly influence the stability of electric block walking; The region of interest of electric block is under a kind of disadvantageous state of stress for a long time, may makes it tired and influence the safety of its service life and use.In addition, Chinese patent 93226708.4 disclosed " mono beam overhead crane box girder ", it makes processed complex, and consumption of materials is big.
Summary of the invention
Technical problem to be solved in the utility model be provide at above-mentioned prior art present situation a kind of operate steadily reliable, safety in utilization is good, manufacturing process is simple relatively and the mono beam overhead crane of economical with materials.
The utility model is to solve the problems of the technologies described above the technical scheme of being taked to be: this kind mono beam overhead crane, it comprises girder, electric block and is used for the trolley mechanism of suspended cables, the base plate of girder is provided with the track that the road wheel that is fit to electric block moves thereon, it is characterized in that it is the horizontal wheel of orbit with the girder sidewall that described girder both sides respectively are combined with at least one, and the rotating shaft of described horizontal wheel is fixedly connected on the electric block.The setting of horizontal wheel is to limit the side travel of electric block road wheel, its end face can not be contacted with the girder sidewall and cliding friction takes place.
The orbit of described horizontal wheel is the sidewall of kingpost baseplate.
Be the thrust laterally that the road wheel of eliminating electric block may be subjected to, the road wheel of described electric block is preferably designed as cylindrical, and the orbital plane that cooperates with described road wheel is designed to horizontal plane.
Described girder is the box girder that is made of upper cover plate, two coxostermums, middle gusset and base plate.Two coxostermums of girder need not connect weldering " L " shape shaped steel separately, have both reduced the step in original technology, have saved about 10% material again.
Described trolley mechanism comprises the several strut bars that are disposed on girder one side, is installed with on the strut bar and girder open parallel " C " shape channel-section steel down, and several cable hanging units are housed in the channel-section steel; Described cable hanging unit comprises: two rollers that are installed in same little axle two ends, but the middle part of little axle is connected with the suspension bracket of a clamping cable.Such design has light and handy, convenient, the safe and reliable and attractive in appearance advantage of sliding.The number of aforementioned strut bar is enough to bear channel-section steel, to be installed in the weight of cable hanging unit in the channel-section steel and supporting cable for foundation is set; The number of cable hanging unit is foundation so that cable moves with electric block.
Compared with prior art, advantage of the present utility model is: 1, because of having increased horizontal wheel and having adopted columniform road wheel, the operation stability of electric block and safety are greatly improved, especially improved its lateral stability; 2, adopt novel box girder, reduced the complexity of manufacturing process and saved material; 3, the coxostermum because of girder need not weld a L shaped plate separately, thus can reduce the height of girder, thus can increase the rise that opens of hoisting crane.
