Abstract
The invention provides a log grabbing device, belonging to the field of log grabbing devices. The log grabbing device comprises an internal grabbing arm (1), a rotation body (2), a bracket (3), an external grabbing arm (4), a synchronous connecting rod (5) and a hydraulic oil cylinder (6); the internal grabbing arm (1) and the external grabbing arm (4) are connected with the hinge axis of the bracket (3); one end of the synchronous connecting rod (5) is connected with the hinge axis of the internal grabbing arm (1) and the other end thereof is connected with the hinge axis of the external grabbing arm (4); one end of the hydraulic oil cylinder (6) is connected with the hinge axis of the internal grabbing arm (1) and the other end thereof is connected with the hinge axis of the external grabbing arm (4); and the rotation body (2) is arranged on the bracket (3) and connected with the hydraulic oil cylinder (6) by an oil pipe. The log grabbing device has the advantages that the round material can be quickly loaded and unloaded by few operators in limited space, the function of a crane is enlarged, the operation is convenient, duration of wearing is achieved, and the application range of engineering machines is enlarged when the log grabbing device is arranged on the engineering machines such as automobile cranes and truck-mounted cranes.
Description
Technical field
The present invention relates to a kind of gripping apparatus of putting circular material that grasps and unload, particularly a kind of rough log gripping apparatus.
Background technology
At present, people are grasping and are unloading when putting circular material and being round log, the comparatively advanced hanging method that adopts be with artificial earlier an end of round log is started after, tie up with the lifting rope again, and then round log is sling with hoisting crane or other hanging device, descend, put down after moving to correct position, rethink way and will lift rope from round log extraction down, grasp or unload to put when circular material is round log and quite bother, the auxilian who needs during work is more, and have bigger potential safety hazard, and inefficiency, labor intensity is big.
Summary of the invention
The objective of the invention is to provide a kind of: high efficiency, the rough log gripping apparatus that labor intensity is little.
The object of the present invention is achieved like this: this rough log gripping apparatus includes interior gripping arm (1), swivel (2), support (3), outer gripping arm (4), synchronising (connecting) rod (5) and hydraulic ram (6), interior gripping arm (1) is connected with support (3) hinge with outer gripping arm (4), synchronising (connecting) rod (5) one ends are connected with interior gripping arm (1) hinge, and the other end is connected with outer gripping arm (4) hinge; Hydraulic ram (6) one ends are connected with interior gripping arm (1) hinge, and the other end is connected with outer gripping arm (4) hinge; Swivel (2) is contained on the support (3), is connected with hydraulic ram (6) by oil pipe.
Beneficial effect: owing to adopted such scheme, from swivel, tell two-way hydraulic oil: the gerotor motor in one road hydraulic oil control swivel, utilize the rotation of motor to control the direction rotation of gripping apparatus; Another road hydraulic oil modulated pressure oil cylinder utilizes stretching of hydraulic ram to control the closure and the unlatching of inner arm and outer gripping arm, thereby realizes the extracting of circular material and unload putting.The grasp force that this gripping apparatus is firm makes it to be fit to very much the loading operation of circular material, because its 360 ° of rotations, accurate positioning need not change the position of hoisting crane, utilize the hydraulic rotating body to change the extracting direction in all directions by 360 ° of degree, both enlarge operating range, increased substantially work efficiency again, can be widely applied to all trades and professions, convenient working, durable in use, high efficiency, labor intensity is little, has reached purpose of the present invention.
Advantage of the present invention: can be in limited space and less operating personal, circular material is carried out the fast speed loading and unloading, expanded the function of hoisting crane, operation is convenient, durable in use, be contained in construction machinery and equipment is on car hosit, the lorry-mounted crane, has expanded the range of use of construction machinery and equipment.
Description of drawings
Fig. 1 is a constructional drawing of the present invention.
Fig. 2 is the plan structure figure of Fig. 1.
The specific embodiment
Embodiment 1: embodiment 1: the object of the present invention is achieved like this: this rough log gripping apparatus includes interior gripping arm 1, swivel 2, support 3, outer gripping arm 4, synchronising (connecting) rod 5 and hydraulic ram 6.Interior gripping arm 1 is connected with support 3 hinges with outer gripping arm 4, and synchronising (connecting) rod 5 one ends are connected with interior gripping arm 1 hinge, and the other end is connected with outer gripping arm 4 hinges; Hydraulic ram 6 one ends are connected with interior gripping arm 1 hinge, and the other end is connected with outer gripping arm 4 hinges; Swivel 2 is contained on the support 3, is connected with hydraulic ram 6 by oil pipe.
Principle of work: utilize and tell two-way hydraulic oil in the swivel: the gerotor motor in one road hydraulic oil control swivel, utilize the rotation of motor to control the direction rotation of gripping apparatus; Another road hydraulic oil modulated pressure oil cylinder utilizes stretching of hydraulic ram to control the closure and the unlatching of interior gripping arm and outer gripping arm; The effect of synchronising (connecting) rod is the synchronous working of the inside and outside gripping arm of control, by the combined action of above mechanism, puts thereby the convenience that realizes circular material grasps and unloads.
Claims (1)
1, a kind of rough log gripping apparatus, it is characterized in that: this rough log gripping apparatus includes interior gripping arm (1), swivel (2), support (3), outer gripping arm (4), synchronising (connecting) rod (5) and hydraulic ram (6), interior gripping arm (1) is connected with support (3) hinge with outer gripping arm (4), synchronising (connecting) rod (5) one ends are connected with interior gripping arm (1) hinge, and the other end is connected with outer gripping arm (4) hinge; Hydraulic ram (6) one ends are connected with interior gripping arm (1) hinge, and the other end is connected with outer gripping arm (4) hinge; Swivel (2) is contained on the support (3), is connected with hydraulic ram (6) by oil pipe.
