Abstract
The utility model provides a general hydraulic crane. The general hydraulic crane comprises a base which is provided with a tower body by a rotary support and is internally provided an oil pump set, wherein the tower body is internally provided with a rotary mechanism; an operation mechanism is arranged at the top of the tower body; a hanging arm is hinged with one side of the top of the tower body and a hoisting winch is mounted on the upper part of the hanging arm; a pulley block is mounted at the head of the hanging arm; one end of a steel wire rope is connected with the hoisting winch and the other end of the steel wire rope penetrates through the pulley block to be connected with a hanger; a first fixed piece is arranged on one side of the lower part of the tower body and a second fixed piece is arranged at the bottom of the hanging arm; an amplitude variation oil cylinder is mounted between the first fixed piece and the second fixed piece; an angle indicator is arranged on the side part of the hanging arm and an angle between the hanging arm and the horizontal direction is 8-15 degrees. The angle between the placed hanging arm and the upper horizontal direction is controlled to be 10 degrees so as to effectively avoid a defect that the hanging arm of the general hydraulic crane shields a tugboat cockpit and improve the use safety.
Description
Technical field
The utility model relates to weight-lifting equipment technical field, especially a kind of General hydraulic hoisting crane.
Background technology
Deck crane, is the large deck machinery of one on ship, and it is a kind of equipment of ship loading and unloading goods.
The General hydraulic hoisting crane being arranged on towboat is mainly for lifting by crane foreign material.General hydraulic hoisting crane is installed on towboat; it is 0 ° (being the angle between arm and horizontal direction) that its arm is normally parked angle; in use; often can block towboat driving compartment part sight line because of arm height problem, and affect the observation to surrounding environment when driving towboat of towboat chaufeur.Make it in operating process, produce certain potential safety hazard.
Utility model content
The applicant is for the shortcoming in above-mentioned existing production technology, a kind of use hydraulic lift rational in infrastructure is provided, thereby change the angle that arm is parked, the defect that actv. has avoided General hydraulic crane arm to block towboat driving compartment, has improved safety in utilization.
The technical scheme that the utility model adopts is as follows:
A kind of General hydraulic hoisting crane, comprise base, on described base, by pivoting support, tower body is installed, is positioned at base oil pump unit is installed, in described tower body, swing type mechanism is installed, the top that is positioned at tower body is provided with operating mechanism, be positioned at tower body top one side and be hinged with arm, the top of described arm is provided with hoister winch, and the head that is positioned at arm is installed polyspast, one end of steel rope is connected with hoister winch, and the other end of steel rope is through polyspast connecting shackle; Described tower body bottom one side is provided with the first connecting element, and the bottom of described arm is provided with the second connecting element, between described the first connecting element and the second connecting element, amplitude oil cylinder is installed; The sidepiece that is positioned at arm is provided with angle index, and the angle between described arm and horizontal direction is 8 °-15 °.
As the further improvement of technique scheme:
Angle between described arm and horizontal direction is 10 °.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, reasonable, make with easy for installation, by the demonstration of angle index, the angle that the angle that arm is parked is controlled between upper horizontal direction is 10 °, the defect that actv. has avoided General hydraulic crane arm to block towboat driving compartment, has improved safety in utilization.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, operating mechanism; 2, tower body; 3, pivoting support; 4, hoister winch; 5, the first connecting element; 6, amplitude oil cylinder; 7, angle index; 8, the second connecting element; 9, arm; 10, steel rope; 11, polyspast; 12, suspension hook; 13, deck; 14, oil pump unit; 15, base.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, the General hydraulic hoisting crane of the present embodiment, comprise the base 15 being installed on ship deck 13, on base 15, by pivoting support 3, tower body 2 is installed, be positioned at base 15 oil pump unit 14 is installed, in tower body 2, swing type mechanism is installed, the top that is positioned at tower body 2 is provided with operating mechanism 1, be positioned at tower body 2 top one sides and be hinged with arm 9, the top of arm 9 is provided with hoister winch 4, the head that is positioned at arm 9 is installed polyspast 11, and one end of steel rope 10 is connected with hoister winch 4, and the other end of steel rope 10 is through polyspast 11 connecting shackles 12; Tower body 2 bottom one sides are provided with the first connecting element 5, and the bottom of arm 9 is provided with between the second connecting element 8, the first connecting elements 5 and the second connecting element 8 amplitude oil cylinder 6 is installed; The sidepiece that is positioned at arm 9 is provided with angle index 7, and the angle a between arm 9 and horizontal direction is 8 °-15 °.
Angle a between arm 9 and horizontal direction is 10 °.Its concrete angle value, can according to practical application need adjust, arm 9 is reached do not block driving compartment sight line to be as the criterion.
When General hydraulic hoisting crane is during in off working state, arm 9 slowly need be put down it by amplitude oil cylinder 6, until arm 9 is 10 ° only (amplitude oil cylinder 6 also will be retracted completely when the time comes) with horizontal direction.Safe and reliable.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
