Embrace clamp device

Technical field

The utility model relates to fork truck and embraces the folder field, relates in particular to the high armful clamp device of a kind of jaw stability.

Background technology

Fork truck is the vehicle of industrial carrying; Promptly to the member pallet cargo load and unload, the various opinion thing carrying vehicles of stacking and short-distance transportation operation; The ISO/TC110 of International Standardization Organization is referred to as industrial vehicle; Belong to material handling machinery, be widely used in station, harbour, airport, factory, warehouse, use oil-burning machine or battery-operated usually.China just made and can use fork truck since early 1950s, had replaced the mode of utilizing a dead lift, had not only mentioned efficient greatly, had saved manpower, also greatly reduced the generation of the personnel casualty accidents that causes because of carrying simultaneously.But, for the carrying of large cargo, because the Heavy Weight of goods, and quantity is many; Can not satisfy its demand for existing fork truck, such as in the manufacturer that makes fragment of brick, because the fragment of brick number of producing is many, and Heavy Weight; Using existing fork truck according to can not complete operation, because the folder dynamics of embracing of fork truck is too little, even use the existing folder of embracing that is used for carrying fragment of brick specially, what generally adopt be the form of left and right sides jig arm; Dynamics is big inadequately, and pressing from both sides the number of grabbing fragment of brick can not be too much, and after the gripping, in the process of transportation; Occur falling the phenomenon of brick easily, can make that not only the efficient of carrying is low, also cause the damaged phenomenon of fragment of brick that falls down.

Summary of the invention

The purpose of the utility model embodiment is: a kind of armful of clamp device is provided, has folder and grab great efforts, press from both sides the high characteristics of stability of grabbing.Concrete technical scheme is following:

A kind of armful of clamp device that the utility model embodiment provides comprises frame, crossbeam, oil cylinder, jig arm and clamp head; Said crossbeam hangs in said frame below, and said crossbeam and said frame are positioned at the same horizontal direction of differing heights; The movable respectively two ends of being fixed in said crossbeam of said jig arm; One end of said oil cylinder is fixed in the middle part of said crossbeam, and the other end of said oil cylinder is fixed in the end of said jig arm; Said clamp head is fixed in another end of said jig arm, and said clamp head comprises matrix and cramping body; Said matrix is fixed in the end of jig arm through screw, and said cramping body is an elastic body, and said cramping body is fixed on the said matrix.

Optional, said frame, crossbeam and clamp head respectively are set to a pair of respectively, and said oil cylinder and jig arm respectively are set to two pairs respectively, and the terminal bonded assembly clamp head that is positioned at the jig arm of said crossbeam the same side is same.

Optional, between the jig arm of said crossbeam the same side, also be provided with pillar stiffener.

Optional, also comprise hydraulic pressure unit; Said hydraulic pressure unit is connected through oil circuit with said oil cylinder.

Optional, said hydraulic pressure unit is provided with display terminal.

Optional, said oil cylinder is provided with by pass valve.

Therefore the technical scheme of application the utility model embodiment is broken the existing mode that folder adopts left and right sides jig arm of embracing; Said jig arm is changed into the mode of front and back; Be the same horizontal direction that said crossbeam and said frame are positioned at differing heights, the movable respectively two ends of being fixed in said crossbeam of said jig arm, an end of said oil cylinder is fixed in the middle part of said crossbeam; The other end of said oil cylinder is fixed in the end of said jig arm; Then the contraction of said oil cylinder drives said jig arm and draws close toward the middle part, thereby steps up the goods between said clamp head, in the rising of frame, mentions then; And deliver to the sky of carrying point through feedway, in descending through said frame again then the said goods carrying point that is positioned over is steadily got final product.Described armful of clamp device of the utility model, the frame of employing, crossbeam and clamp head all are a pair of, said oil cylinder and jig arm respectively are two pairs respectively; Simultaneously, the terminal bonded assembly clamp head that is positioned at the jig arm of said crossbeam the same side is same, and said clamp head is made up of matrix and cramping body; Said matrix is fixed in the end of said jig arm; Said cramping body is an elastic body, is convenient to adapt to the surface of various goods, and produces bigger friction force; Thereby make said goods of being grabbed firm with family in the process of transporting, be unlikely to fall down and break by folder.In this engineering; Said oil cylinder is connected with hydraulic pressure unit through oil circuit; Said hydraulic pressure unit provides said oil cylinder stable power; Simultaneously said hydraulic pressure unit is provided with display terminal, and the force value when showing said armful of folder work can be used for reminding the user can be because of the excessive phenomenon that causes the goods of crushing of the unit pressure that uses.

Description of drawings

Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, does not constitute the improper qualification to the utility model, in the accompanying drawings:
