Description
Technical field
The present invention relates to a kind of electric block, especially a kind of lockable Electric Chain Blocks.
Background technology
The features such as electric block is a kind of extraordinary weight-lifting equipment, and be installed on overhead traveling crane, gauntry crane, it is little that electric block has volume, from heavy and light, simple to operate, easy to use, for industrial and mining enterprises, the places such as storage harbour.Electric block can be sling high for weight or hang another place from one, but the object in handling process is space to be moved, electric block mostly needs to be suspended on crossbeam, therefore need longer rope to move up and down to pull suspension hook, existing electric block adopts steel cable to pull mostly, and steel cable is flexible convenient, when steel cable pull-up, unnecessary steel cable reels in the outer ring of cylinder, and the shortcoming of the program is one is that steel cable weight capacity is poor, cannot be applicable to large-tonnage electric block; Two is that unnecessary steel cable easily causes winding when cylinder reels outward.Therefore someone designs and adopts chain to pull suspension hook, chain strength is high, weight capacity is good, and drive chain lifting by the gear teeth of transmission gear, the chain unnecessary when rising falls into the bag of dress chain from the another side of transmission gear, but, chain is all formed by connecting by chain link, after long-term use, is easy to loosen easily knotting between chain link, when folding and unfolding chain very easily in causing stuck phenomenon, be easy to cause damage to article and electric block.
Summary of the invention
In order to overcome the problems referred to above, the invention provides that a kind of structure is simple, the lockable Electric Chain Blocks of use safety.
Technical scheme of the present invention is to provide a kind of lockable Electric Chain Blocks, it comprises casing, motor, sprocket wheel, chain and transmission device is provided with in described casing, it is characterized in that: described sprocket wheel is arranged at the middle part of described casing, the side of described sprocket wheel is provided with described motor, the opposite side of described sprocket wheel is provided with a change speed gear box, and described sprocket wheel is connected on described change speed gear box by a roll shaft, and the side of described roll shaft is provided with a locking device.
In a preferred embodiment of the present invention, described lower box includes a button switch, and described button switch is connected in described casing by a button cable, and described button switch connects described locking device.
In a preferred embodiment of the present invention, be provided with a main frame in described casing, described button switch, described locking device and described motor are all connected on described main frame.
In a preferred embodiment of the present invention, described tank floor is positioned at and offers one bottom sprocket wheel and go out chain hole, goes out chain hole and hangs in the below of described casing, be connected with a suspension hook bottom described chain described in described chain passes through.
In a preferred embodiment of the present invention, be provided with the collection chain box that deposits described chain below described casing, described chain to be arranged on described sprocket wheel and to extend in described collection chain box.
In a preferred embodiment of the present invention, the top of described suspension hook is provided with a buffering block.
Electric Chain Blocks of the present invention is provided with motor, sprocket wheel, chain and transmission device as its basic structure in casing, the speed that change speed gear box rises for changing chain and declines is provided with in the side of sprocket wheel, roll shaft on sprocket wheel connects change speed gear box, one end of roll shaft is provided with a locking device can locking device timely when running into the dangerous situations such as knotting, prevents from causing danger.It is simple that the present invention has structure, the advantages such as use safety.
