Abstract
The utility model relates to a flat-jaw volume-changeable grab bucket for loading and unloading. The grab bucket comprises an upper supporting beam, a lower supporting beam, a supporting rod which is hinged with the upper supporting beam, a jaw plate which is hinged with the supporting rod and a wire rope. The grab bucket is characterized in that the jaw plate is a flat plate type, and a volume changing device which is used for increasing the whole cargo grabbing volume of the grab bucket is arranged on the flat plate type jaw plate. The grab bucket has the advantages that ores can be prevented from attaching to the jaw plate effectively, full-loading operation of the grab bucket is guaranteed, the operation efficiency is improved, ores attached to the grab bucket are prevented from falling with a machine when the grab bucket is returned, persons and the machine cannot be harmed, the volume changing device is arranged on the jaw plate, an operator can put the volume changing device down and enables the volume changing device to be in abutting joint with a flat plate in accordance with actual conditions, the whole cargo grabbing volume of the grab bucket is increased and the full-loading effect is achieved.
Description
Technical field
The utility model belongs to the handling equipment technical field, particularly relates to a kind of loading and unloading and grabs bucket with flat jaw transfiguration.
Background technology
Ore refers to the stone that gets off to contain certain valuable mineral matter by adopting in the mine, ore can be applied in the engineering fields such as metallurgical industry, chemical frbre industry, building industry, iron (public affairs) road unit in charge of construction, cement industry and sandstone industry after the processing step by step through fragmentation, grinding etc., is one of Very Important Cargo of harbour handling.In the prior art, the harbour generally adopts following equipment that ore is carried out ship-discharging operation:
Connect the special-purpose grab bucket of ore at the door machine, utilize grab bucket with the ore crawl deliver from vault of boats and ships carrying.Above-mentioned grab bucket tool is a plurality of the bucket lobe, in loading and unloading operation, utilizes opening and closure of grab bucket bucket lobe, ore is grasped deliver from vault unload to harbour.But because the quality of ore is different, the loading and unloading difficulty has very large difference, is mainly manifested in:
1, the part ore is because viscosity is large, cause the adhesive ability of grab bucket bucket lobe very large, when grab bucket is opened, ore can't draw off fully, causes all sticking a lot of ores on each bucket lobe, because in the process of each crawl ore, all adhere to ore in the grab bucket, cause to reach at full capacity operation; Grab bucket is moved in this process of cabin by harbour, and the ore that is attached in the grab bucket easily falls at random, has the man-machine potential safety hazard of damage.
2, the difference of specific gravity of ore is very large, and grab bucket is in when design, and its volume is proportion in the middle of selecting, and therefore when the less ore of loading and unloading proportion, even grab bucket can be grabbed full goods, but weight capacity can not reach at full capacity, and then affects handling efficiency.
Summary of the invention
The utility model for solve the technical matters that exists in the known technology provide a kind of can effectively reduce the adhesion amount of ore in grab bucket, and can be according to ore proportion volume adjusted, the loading and unloading of raising handling efficiency are grabbed bucket with flat jaw transfiguration.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
Loading and unloading are grabbed bucket with flat jaw transfiguration, comprise upper beam, lower support beam, with the hinged strut of upper beam, with the hinged jaw of strut and and steel rope, it is characterized in that: described jaw is flat jaw, and described flat jaw is provided with for increasing the whole positive-displacement apparatus of grabbing the goods volume of grab bucket.
The utility model can also adopt following technical scheme:
Described positive-displacement apparatus comprises and colludes plate, transfiguration plate and flat board, describedly collude plate one end and lower support beam is hinged, described transfiguration plate lower end by folding with to collude plate hinged, when transfiguration plate upper end is in folded state by bolt with collude plate and be connected, be connected with otic placode on the described flat board and with to collude plate affixed.
Be connected with otic placode on the described transfiguration plate.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, be that jaw adopts plate armature, can effectively prevent from sticking in jaw owing to ore is squeezed, so not only guarantee at full capacity operation of grab bucket, improve operating efficiency; Ore attached thereto falls at random in return process but also can prevent from grabbing bucket, and avoids occurring damaging man-machine potential safety hazard.Be provided with positive-displacement apparatus at jaw, operating personal can be according to the actual job situation, positive-displacement apparatus is put down with flat board dock, increase grab bucket whole grab the goods volume, reach and be loaded with full the load effect.

The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1-Fig. 4, loading and unloading are grabbed bucket with flat jaw transfiguration, comprise upper beam 3, lower support beam 5, strut 4, six uniform with strut hinged jaw 6, steel rope 2 and the chains 1 hinged with upper beam, described jaw is flat jaw, and described flat jaw is provided with for increasing the whole positive-displacement apparatus of grabbing the goods volume of grab bucket.In the present embodiment, described steel rope 2 one ends and upper beam 3 are affixed, and rotate and be installed in pulley gear on upper beam 3 and the lower support beam 5, pass from upper beam; Described chain 1 is connected by the otic placode of shackle with the upper beam top.
