Embodiment Construction
[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0024] Such as Figure 1-4 As shown, the embodiment of the present invention provides an electric hoist for a single-beam crane, which includes a crane main beam 1, an electric hoist body 2 for lifting heavy objects, and an electric hoist body 2 for driving the electric hoist body 2 to move. The driving device 3 of the crane is fixedly connected to the surface of the main beam 1 of the crane with a track groove 4, the driving device 3 is electrically conne...

The invention provides an electric block used for a single-beam crane and relates to the field of electric blocks. The electric block comprises a crane main beam used for supporting and providing a walking rail, an electric block body used for lifting a weight and a driving device used for driving the electric block body to move. A rail groove is fixedly connected to the surface of the crane mainbeam, and a wire used for providing electric power for the driving device is electrically connected to the driving device. A wheel used for moving is installed on the driving device. A negative absorption oil bag is fixedly connected to the inner wall of the rail groove. After the electric block used for the single-beam crane is used, an electromagnet block is powered off, a steel wire brush losesmagnetism, wood bits and scrap iron twisted off through friction can fall or can be directly flushed through water, and therefore the problem that when a common electric block used for a single-beamcrane is used in a comprehensive workshop, metal chips and wood bits are likely to be mixed in the lifting process of a steel wire rope, the rolling friction force of the steel wire rope is improved,and the service life of the electric block is severely affected is solved effectively.
Description
Technical field [0001] The invention relates to the technical field of electric hoists, in particular to an electric hoist for a single beam crane. Background technique [0002] At present, the electric hoist is a kind of lifting equipment. The electric hoist has the characteristics of small size, light weight, simple operation and convenient use. Among them, the electric hoist for single-beam cranes is mainly used in the mechanical manufacturing workshop, and the single-beam crane is more convenient to use in the workshop. It does not occupy the ground and will not hinder the manufacturing work of the workshop. However, due to the special working environment in some workshops, the electric hoist on the single beam crane is not suitable for use. In the integrated mechanical workshop where wood and metal are processed and assembled together, due to the need to For the combined installation of heavy wood and large metal, in order to shorten the distance of the project and improve t...
