Abstract
The utility model relates to an electric grab bucket for bulk materials, comprising an anti-hooking apparatus, an upper supporting beam, a lower supporting beam, a wire rope, a bucket body, bar stays and open and close bucket limiting apparatus. A hoisting special motor, a stopper, a speed reducer, a wire rope reel, a bearing block and an open bucket limiting apparatus are arranged on the upper part of the upper supporting beam, and a fixed pulley block is arranged on the lower part of the upper supporting beam; a movable pulley block is arranged on the lower supporting beam, and the wire rope is winded among the wire rope reel, the movable pulley block and the fixed pulley block. The close bucket limiting apparatus is arranged between upper and lower supporting beams. The bucket body adopts that the lower hinge point is arranged on the main rib plate of the middle part of the bucket body, and the bar stay force is transmitted to the cutting edge of the bucket grab by the main rib plate; bar stays set between the upper supporting beam and the bucket body adopts a variable cross-section box type construction, and two bar stays are parallel, and this eliminates the horizontal component force from bar stays to the bucket body. The utility model can at will select multiplying power of pulley block which are adapt to grab, and it has open and close bucket limiting apparatus which can prevent the motor from being damaged. The entire bucket grab has the advantages of reasonable structural arrangement and good rigidity, and it is uneasy to deform, etc.
Description
Technical field
The utility model relates to a kind of being attached on the elevator machineries such as hoisting crane, gauntry crane, is used for the motor grab that goods yard loading and unloading bulk goods is used.
Background technology
At present, motor grab is to use the switching mechanism of electric block as grab bucket, the closure rope is wound on the assembly pulley of the electric block that is located at deck beam below and through beam.Because grab bucket each several part distribution of weight is difficult to rationally, the less stable of grab bucket, the electric block that is located at deck beam below can be toppled over and swings along with grab bucket, steel rope is easy to take off groove, rope guide on the electric block also is easy to damage, the electric block that stretches out grab bucket deck beam two ends also is easy to break, and the motor grab pulley block ratio of this structure is generally 2 multiplying powers, a balance wheel parallel with cucurbit generally only can be installed again in the deck beam below, be not easy to choose the pulley block ratio that is fit to grasp performance, and with the grab bucket of motor drives bolt and nut transmission, only be suitable for small-sized grab bucket and use.They are not generally all opened bucket and close the bucket inhibiting device.
Summary of the invention
The purpose of this utility model just provides a kind of as the rope grab bucket, chooses the pulley block ratio that is fit to grasp performance arbitrarily; And switching mechanism does not stretch out deck beam, and closed rope is not swung, and is difficult for taking off groove, the electronic bulk goods grab bucket that has protection motors such as opening and closing the bucket inhibiting device not burnt.
Electronic bulk goods grab bucket of the present utility model is made up of lock hook device, deck beam, through beam, steel rope, bucket body, strut and switching bucket inhibiting device.The grab bucket switching mechanism power system that installation is made up of lifting motor special, drg, reductor and cable drum on deck beam, the fixed pulley of the closed assembly pulley of installation below deck beam, the movable pulley of closed assembly pulley is installed on the through beam, and steel rope is wound between cable drum, movable pulley, the fixed pulley.The assembly pulley number is determined by pulley block ratio and winding rope mode, general through beam can be adorned 4 pulleys, deck beam can be adorned 2～4 pulleys, pulley block ratio can reach 4～5, hinge is positioned on the main gusset at bucket body middle part under the bucket body employing strut, strut power reaches the grab bucket cutting edge by main gusset, and the lateral support that is supported between bucket body side plate and the main gusset has been strengthened bucket body rigidity.Strut adopts the variable section box type construction, and two struts are parallel, has eliminated the horizontal component of force of strut to the bucket body effect, and the bucket body stressing conditions is better.Open the afterbody that the bucket inhibiting device is located at cable drum, adopt the control of LX7 travel switch, opening the maximum position that struggles against is the automatic cutout power circuit.Close the bucket inhibiting device and be contained between the through beam automatic cutout power circuit when bucket body closes.

Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model deck beam structural representation;
The specific embodiment
Electronic bulk goods grab bucket comprises lock hook device 1, deck beam 2, through beam 5, steel rope 16, bucket body 6, strut 9.Lifting motor special 11, drg 10, reductor 15, cable drum 14, bearing seat 12 are installed on deck beam 2 and are driven bucket inhibiting device 13.Fixed pulley group 3 is installed below the deck beam 2, and through beam 5 is equipped with running block 4 on it between two main gussets 8 of bucket body 6, and steel rope 16 is wound between cable drum 14, running block 4, the fixed pulley group 3. Deck beam 2,5 of through beams are equipped with and close bucket inhibiting device 17.Strut 9 between deck beam 2 and bucket body 6 adopts the variable section box type construction, and two struts 9 are parallel, bucket body 6 adopts 9 times hinges of strut to be positioned on the main gusset 8 at bucket body 6 middle parts, and strut power reaches grab bucket cutting edge 7 by main gusset 8, does not have the horizontal component of force of effect and bucket body 6.
