Abstract
The utility model relates to an industrial accessory used for carrying out the irregular material handling of waste steel. Figure one describes a multi-clack gravity grab bucket for loading and unloading waste steel, and the grab bucket is composed of a guide rail, an upper beam, jaw clacks, a pulley block, a strut and a support. The guide rail passes through the upper beam and is connected with the support, the pulley wheel arranged at the head of the jaw clacks and a sliding sleeve are hinged and supported in the guiding groove on the support through a pin. Each jaw clack can rotate around the pin and can also move from the top to the bottom along the guiding groove, which causes each of the jaw clacks to be closed according to the shape of the material. The utility model solves the material leakage phenomenon existing in the original grab bucket and has the advantages of high reliability, high efficiency and accurate movement.
Description
The present invention is a kind of worker's accessory that is used for irregular material loading and unloading such as steel scrap.
Along with developing rapidly of China's steel and iron industry, steel scrap is as the important source material of steel-making, and the parent who more and more is subjected to people hides.But because the type and the grade of steel scrap are various, shape, different sizes, weight differs, and has brought very big difficulty for the loading and unloading of steel scrap.
In the prior art, be used for worker's accessory of steel scrap loading and unloading, can be divided into two classes by operating principle, one class is the dynamical type grab bucket, comprise hydraulic grab, motor grab etc., the grab bucket of this class needs the external energy in use, if on the Kaijiang boats and ships of energy free or the abominable place of service condition just can't operation.Another kind of is the gravity type boat davit grab bucket, in " elevator machinery " book that China Machine Press publishes, represented a flexible many jaws lobe grab bucket that links, it is by deck beam, jaw lobe, assembly pulley, strut are formed, each pulley of downslide wheels is contained in the head of each jaw lobe respectively, opens and closes rope and walks around these pulleys successively.But because bucket body is flexible the connection with the jaw lobe, only between two jaw lobes, there is chain to connect, make the motion of jaw lobe be random state, grab bucket very easily causes the pulley on pulley and each jaw lobe on the deck beam up and down can not be corresponding when the irregular material of gripping, the wearing and tearing of steel rope and wheel rim have been increased, even cause the steel rope chute, simultaneously owing to be subjected to checking and balance of chain between the jaw lobe, make each jaw lobe can only be in limited scope asynchronous behavior, when the material shapes of gripping differs greatly or two adjacent jaw lobes when clamping an irregular material, the just cisco unity malfunction of grabbing bucket has directly influenced the raising of handling efficiency.
The purpose of not inventing is to design many lobes gravity grab bucket of an asynchronous closure, make each jaw lobe of grab bucket distinguish closed according to the shape of material, when in case a pair of jaw lobe or two adjacent jaw lobes occurring and clamping an irregular material, other jaw lobe is interference-free, still can move respectively, until complete closure, spill leakage to prevent goods.
Solution of the present invention is: design a support, one group of guide groove is arranged on the support, at jaw lobe head pulley and slippage cover are housed, by bearing pin the pulley of jaw lobe head and slippage are overlapped in the hinged guide groove on support, under the effect that opens and closes rope, make each jaw lobe to rotate around bearing pin respectively, can slide up and down along the guide groove on the support again, thereby reach asynchronous closure, simultaneously in order to prevent the support upset, be provided with guide rail in grab bucket, guide rail passes deck beam, lower end and support and connects, and guide rail can be slided up and down along deck beam.
The front view of many lobes gravity grab bucket of accompanying drawing 1, loading and unloading steel scrap
The mode of operation of many lobes gravity grab bucket support of accompanying drawing 2, loading and unloading steel scrap
Fig. 1 has described many lobes gravity grab bucket of steel scrap loading and unloading, and it is made up of guide rail 1, deck beam 2, support 3, strut 4, jaw lobe 5.One end of guide rail 1 and support 3 connect, one end passes one group of guide groove 6 on deck beam 2, the support 3, head at jaw lobe 5 is provided with pulley 7 and slippage cover, hinged in the guide groove 6 of support 3 by bearing pin 8 the pulley 7 of jaw lobe 5 heads and slippage cover, support 3 top sheave groups to press holding position corresponding with the assembly pulley on the deck beam 2, open and close rope 9 and walk around these pulleys in pairs successively, for actv. prevents material from leakage, the bottom of jaw lobe 5 is an odontoid.Along with the rising that opens and closes rope 9, jaw lobe 5 is with the size of material resistance, and closed degree has nothing in common with each other, when a pair of jaw lobe or adjacent jaw lobe clip material, all the other jaw lobes continue closure without interruption, or rotate around bearing pin, or move up along guide groove, until complete closure, along with the continuation that opens and closes rope is risen, grab bucket is raised, when grab bucket run to unload stockpile after, support that rope promotes, the switching rope descends, grab bucket is opened, realize unloading action.
Fig. 2 has described the mode of operation of many lobes gravity grab bucket support of steel scrap loading and unloading.Support 3 is the polygon steel shelf structure identical with jaw lobe number, every limit is provided with two guide groove plates 11, on the guide groove plate 11 guide groove is arranged, guide groove is uniform on support, the pulley 6 of plate 5 heads and slippage is overlapped 10 hinged in the guide groove of support 3 by bearing pin 8.
On probation showing, many lobes gravity grab bucket action of these loading and unloading steel scrap accurately, dependable performance, overcome the leakage phenomenon that existing many lobes gravity grab bucket exists when grasping irregular material, improved the efficiency of loading and unloading, promoted safety in production.
Claims (2)
1, is used for many lobes gravity grab bucket of steel scrap loading and unloading, it is by deck beam, strut, jaw lobe, assembly pulley are formed, it is characterized in that said many lobes gravity grab bucket, there are guide rail, support, jaw lobe head that pulley and slippage cover are housed, guide rail and support connect, and one group of guide groove is arranged on support, and be hinged in the guide groove of support the pulley of jaw lobe head and slippage cover by bearing pin.
2, by the described many lobes gravity grab bucket of claim 1, it is characterized in that the guide groove on the said support is uniform.
