Leveling chopping machine feeding crane
Technical field
The utility model relates to a kind of feeding elevating apparatus, especially a kind of leveling chopping machine feeding crane.
Background technology
In existing automatic industrial equipment, often need to article to be processed or batching be transported on the control position of equipment by lifting structure by apparatus for automatically lifting, or from processing stations, the product machining is shifted out, increase labour cost, existing automatic lifting structure generally comprises two kinds: a kind of is after product is machined, to be free to fall on material platform, by staff, taken away by hand, this kind of structure is because the height of material platform is different, for different staff, cannot keep unified suitable height, too high sometimes, affect staff's operation, the second way is to drive reductor by electrical motor in addition, reductor connects chain, by chain, connect a crane, thereby drive the lifting of material platform, in operational process, by brake, come control position, once control bad or power-off, crane can run out of steam and free-falling body, there is larger potential safety hazard.
Utility model content
The utility model provide a kind of can automatic lifting, and the controlled leveling chopping machine feeding crane of automatic lifting process safety.
To achieve these goals, the utility model adopts following technical scheme:
Comprise the head bearing locating plate and the lower bearing locating plate that be arranged in parallel, between described head bearing locating plate and lower bearing locating plate, be provided with two parallel screw mandrels, wherein at least one rhizoid bar connects reducing motor by the first chain, between two, by the second chain connection for transmission, on described every rhizoid bar, be socketed a lifting arm.
Preferably, between described head bearing locating plate and lower bearing locating plate, be also provided with the optical axis of answering with every rhizoid pole pair.
Preferably, described lifting arm rear is provided with an extension of extending along lifting arm reversing sense, and described extension is socketed on described optical axis by socket part.
Preferably, described reducing motor is located on lower bearing locating plate.
Preferably, described head bearing locating plate and the screw mandrel installation place on lower bearing locating plate are provided with surface bearing.
Preferably, described lifting arm extension and optical axis connecting portion are provided with linear bearing.
Preferably, described screw mandrel and the first chain and/or the second chain junction are provided with sprocket wheel.
Preferably, described lower bearing locating plate is provided with the adjusting sprocket wheel that regulates the first chain degree of tightness.
Preferably, described head bearing locating plate is a rectangular frame.
Preferably, described lower bearing locating plate is a flat board.
Owing to having adopted said structure, leveling chopping machine feeding crane of the present utility model drives after chain by reducing motor, driving screw mandrel rotates, there is screw mandrel to drive lifting arm to carry out lifting, after reducing motor stops, lifting arm can hover over current position or along screw mandrel slow decreasing, avoided the potential safety hazard that after running out of steam, crane freely declines and brings, and the height of lifting arm can be controlled, its main application is to save artificial, and material pulls away with fork truck after being automatically stacked to bottommost again.

The specific embodiment
As depicted in figs. 1 and 2, the leveling chopping machine feeding crane of the utility model embodiment comprises head bearing locating plate 1 and the lower bearing locating plate 2 be arrangeding in parallel, between described head bearing locating plate 1 and lower bearing locating plate 2, be provided with two parallel screw mandrels 3, wherein at least one rhizoid bar 3 connects reducing motor 5 by the first chain 4, between two rhizoid bars 3, by the second chain 6 connection for transmissions, on described every rhizoid bar 3, be socketed a lifting arm 7.
During work, start reducing motor 5 forward or reverse, reducing motor 5 consists of motor and drop-gear box, reducing motor 5 drives the first chain 4 motions, the first chain 4 drives connected screw mandrel to rotate, this screw mandrel drives other screw mandrels servo-actuated by the second chain 6, thereby drives lifting arm 7 to move up and down on screw mandrel.With apparatus for automatically lifting, can reduce manually, cost-saving, material is delivered on bay-lift, bay-lift arranges an induction installation, and after induction installation senses, bay-lift will be toward declining a bit, until drop to extreme lower position machine, quit work, alarm lamp lights prompting staff material is pulled away, and then bay-lift is raised to induction installation stops, then machine operation voluntarily again.
In order to keep the Stability Analysis of Structures between head bearing locating plate 1 and lower bearing locating plate 2 and screw mandrel 3, increase supporting force, in the present embodiment, between described head bearing locating plate 1 and lower bearing locating plate 2, be also provided with the optical axis 8 corresponding with every rhizoid bar 3.
In order to increase the lifting stationarity of lifting arm 7, in the present embodiment, described lifting arm 7 rears are provided with an extension 9, and described extension 9 is socketed on described optical axis 8.
In the present embodiment, described reducing motor 5 is located on lower bearing locating plate 2.
In the present embodiment, described head bearing locating plate 1 and screw mandrel 3 installation places on lower bearing locating plate 2 are provided with surface bearing 10.
In the present embodiment, described lifting arm extension 9 is provided with linear bearing 11 with optical axis 8 connecting portions.
In the present embodiment, described screw mandrel and the first chain 4 and/or the second chain 6 junctions are provided with sprocket wheel 12.
In the present embodiment, described lower bearing locating plate 2 is provided with the adjusting sprocket wheel 13 that regulates the first chain 4 degrees of tightness.
In the present embodiment, described head bearing locating plate 1 is a rectangular frame.
In the present embodiment, described lower bearing locating plate 2 is a flat board.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification sheets and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
