Abstract
The utility model discloses a spring asynchronous multi-jaw grab, which consists of a grab opening rope, a grab closing rope, an asynchronous mechanism, a support bar, an upper bearing beam, grapple tines, a lower bearing beam, an upper pulley and a lower pulley. The top of the upper bearing beam is equipped with a hanging point which is designed to connect the grab opening rope, and the under side of the upper bearing beam is equipped with a pulley seat which is designed to fix the upper pulley. The top end of the support bar is connected with the upper bearing beam and the lower end is connected with the grapple tines. And the grapple tines are also connected with the lower bearing beam. The top side of the lower bearing beam is equipped with a pulley seat which is used to fix the lower pulley. The upper bearing beam is packaged with the asynchronous mechanism which has a plurality of springs with the same number of the grapple tines. Every spring is connected with the corresponding grapple tine. When the grapple tine is hindered, the utility model will achieve an asynchronous grabbing. The grab increases the weight of the upper bearing beam and decreases the weight of the lower bearing beam, which is favorable for grabbing materials. The utility model increases the unloading efficiency, which is applied to unloading the bulk materials at the yards of the wharf, station or steel mill etc.
Description
Technical field
The utility model relates to a kind of handling tool, especially loads and unloads the asynchronous orange-peel grabs of the employed spring loaded of fitfull bulk materials such as ore, the pig iron, steel scrap.
Background technology
In the stock ground of industries such as harbour, station, steel mill, the asynchronous orange-peel grab of many uses during fitfull bulk materials such as loading and unloading ore, the pig iron, steel.At present, the asynchronous mechanism of the asynchronous orange-peel grab of domestic use mainly contains two kinds of hydro-cushion formula and spring loadeds.The asynchronous orange-peel grab of spring loaded, through beam are provided with the quantity some springs identical with jaw lobe number, and each spring connects a jaw lobe.Because the jaw lobe is subjected to the priority difference of resistance, varied in size by resistance, connected spring deformation in compression is also different, therefore can reach the purpose of the asynchronous extracting of jaw lobe.
The asynchronous orange-peel grab of fluid pressure type, through beam are provided with the quantity some oil cylinders identical with jaw lobe number, and each oil cylinder connects a jaw lobe, and the oil cylinder bottom links to each other and forms permeator.When certain jaw lobe was subjected to resistance and can not advances, coupled oil cylinder piston is stressed to be moved, and to other oil cylinder and promote piston and move, coupled jaw lobe was advanced hydraulic oil pressure, all touched material up to all jaw lobes.So, can reach the purpose of the asynchronous extracting of jaw lobe.
In the above-mentioned prior art, asynchronous mechanism is arranged on the through beam, has increased the weight of through beam, is unfavorable for the extracting of material, promptly is difficult for grabbing full.
The utility model content
Technical problem to be solved in the utility model provides in the asynchronous orange-peel grab of spring loaded of a kind of easy extracting material, high efficiency.
Technical solution of the present utility model is: the asynchronous orange-peel grab of a kind of spring loaded, comprise out the bucket rope, close the bucket rope, asynchronous mechanism, strut, deck beam, the jaw lobe, through beam, top sheave and lower sheave, be provided with above the deck beam and connect the suspension centre of opening the bucket rope, be provided with the fixedly pulley base of top sheave below, the strut upper end is connected with deck beam, the lower end is connected with the jaw lobe, the jaw lobe also is connected with through beam, be provided with the fixedly pulley base of lower sheave above the through beam, it is characterized in that: described asynchronous mechanism is arranged on the described deck beam, described asynchronous mechanism is provided with the some springs identical with jaw lobe quantity, and described each spring is connected with its corresponding jaw lobe respectively.
The beneficial effects of the utility model are: because asynchronous mechanism is arranged on the deck beam, increased the weight of deck beam, alleviated the weight of through beam, helped the extracting to material, improved handling efficiency.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the closure state scheme drawing of the asynchronous orange-peel grab of the utility model spring loaded.
Fig. 2 is the open configuration scheme drawing of the asynchronous orange-peel grab of the utility model spring loaded.
Fig. 3 is the asynchronous seized condition scheme drawing of the asynchronous orange-peel grab of the utility model spring loaded.
Reference numeral: 1 opens the bucket rope, and 2 close bucket rope, 3 asynchronous mechanism, 4 struts, 5 deck beams, 6 jaw lobes, 7 through beams.
The specific embodiment
As shown in the figure, the asynchronous orange-peel grab of spring loaded of the present utility model is by opening bucket rope 1, closing bucket rope 2, asynchronous mechanism 3, strut 4, deck beam 5, jaw lobe 6, through beam 7, top sheave and lower sheave and form.
End that opening bucket rope 1 is fixed on the cylinder of weight-lifting equipment, and the other end is fixed on the suspension centre above the deck beam 5.Closing that bucket rope 2 is walked around top sheave, lower sheave is fixed on the cylinder of weight-lifting equipment.Top sheave is fixed in the pulley base below the deck beam 5, and lower sheave is fixed in the top pulley base of through beam.Being connected between strut 4 and the deck beam 5, between strut 4 and the jaw lobe 6, between through beam 7 and the jaw lobe 6 can be adopted bearing, for reduce axle and and axle sleeve between wearing and tearing, preferably adopt antifriction-bearing box.
Asynchronous mechanism on deck beam 5 is provided with 3 the some springs identical with jaw lobe 6 quantity, and each spring is connected with its corresponding jaw 6 lobes respectively.When jaw lobe 6 was subjected to the material resistance and can not advances, coupled spring was compressed, and all the other jaw lobes then can move on, to reach the purpose of the asynchronous extracting of jaw lobe.
Fig. 1 opens bucket rope 1 this moment and unclamps for closing bucket-shaped attitude, closes bucket rope 2 and mentions, and closes bucket rope 2 and walks around top sheave, lower sheave, and the distance of deck beam 5 with through beam 7 that furthered is so grab bucket is closed.
Fig. 2 opens bucket rope 1 this moment and mentions for opening bucket-shaped attitude, closes bucket rope 2 and unclamps, and under the action of gravity of through beam 7, grab bucket is opened.
Fig. 3 is asynchronous seized condition, and when a certain jaw lobe 6 was subjected to the material resistance and can not advances, coupled spring was compressed, and all the other jaw lobes then can move on, and all touch material up to all jaw lobes and finish closure, reach the purpose of the asynchronous extracting of jaw lobe.
