Abstract
The invention discloses a vehicle crane main arm supporting device capable of changing angles. The vehicle crane main arm supporting device capable of changing angles comprises a suspension arm, a support rod, a support rod base, a support platform and a horizontal driving device, wherein the horizontal driving device consists of two hydraulic cylinders; a second hydraulic cylinder is stably connected to the support rod base; the support rod and the support rod base are connected with each other through a hinge; the support rod is connected to the suspension arm through a ball hinge; the support rod base is connected to the support platform through a rail. Through the overall device, the horizontal driving device plays a role in pushing and pulling the support rod base, so that an included angle between the support rod and the suspension arm is adjusted, the stress of the suspension arm can be relieved, and the hoisting capacity of the crane can be improved; meanwhile, the problem of incapability of properly changing the included angle between the support rod and the suspension arm to relieve the stress of the suspension arm and improve the performance of the crane in the prior art can be solved.
Description
Technical field
The present invention relates to a kind of stressed supporting mechanism device of arm that slows down, specifically a kind of car hosit principal arm bracing or strutting arrangement of variable-angle.
Background technology
Car hosit utilizes the principle hoisting heavy of lever, fulfils assignment.The support of arm is provided by strut bar, stressed larger near fulcrum, because the position of strut bar end is fixed, so cannot regulate between strut bar and arm angle alleviate the stressed of arm.This has just limited the maximum load of hoisting crane, and arm is also higher to the requirement of material.The described stressed supporting construction of alleviation arm, is designed to transportable form the bottom of strut bar, just can address the above problem by actv., improves the performance of hoisting crane.
Summary of the invention:
The car hosit principal arm bracing or strutting arrangement that the object of this invention is to provide a kind of variable-angle, mainly solve in prior art, exist can not appropriate change strut bar and the angle of arm alleviate the problem of performance of the stressed raising hoisting crane of arm.
The technical solution used in the present invention is: a kind of car hosit principal arm bracing or strutting arrangement of variable-angle, comprise arm, and strut bar, strut bar base, support platform and horizontal drive apparatus, described arm is connected with strut bar by spherical hinge.Described horizontal drive apparatus is comprised of two joint hydraulic actuating cylinders, second section hydraulic actuating cylinder is firmly connected with strut bar base, strut bar and strut bar base are connected through the hinge, strut bar base is connected with support platform by track, effect by horizontal drive apparatus to the push and pull of strut bar base, regulates the angle between strut bar and arm.
Described support platform is provided with the run channel of strut bar base, strut bar base can be in support platform parallel motion.
Described support platform is provided with secondary groove and card article.
Know-why and working process:
The problem existing for solving above-mentioned prior art, designed removable strut bar base technical scheme, strut bar base moves under the effect of horizontal drive apparatus in support platform, at support platform a, b, tri-positions of c are fixed by draw-in groove, form firm base for supporting, avoid the unstable impact on hoisting crane performance of base for supporting.Strut bar platform is the transition between strut bar and support platform, and in the time of hoisting crane underloading, support platform just can expire the demand of operation at initial point c, does not need to start horizontal drive hydraulic actuating cylinder.During heavy duty, according to weight and the position of wanting lifting, first strut bar base is pushed to a or b position.
Outstanding advantages of the present invention is:
By changing the position of strut bar base, drive the motion of supporting to regulate the angle between strut bar and arm, alleviated the stressed of arm heavy duty, with respect to existing crane equipment, having hoisting crane Maximum Loading Capacity increases, hoisting crane reduces the requirement of material, the advantage that the overall performance of hoisting crane is improved.
Accompanying drawing explanation
Fig. 1 is that the car hosit principal arm bracing or strutting arrangement of variable-angle of the present invention is when the structural representation of strut bar base position during at c point.
Fig. 2 is that the car hosit principal arm bracing or strutting arrangement of variable-angle of the present invention is when the structural representation of strut bar base position during at b point.
Fig. 3 is that the car hosit principal arm bracing or strutting arrangement of variable-angle of the present invention is when the structural representation of strut bar base position during at a point.
Fig. 4 is the strut bar platform structure schematic diagram of the car hosit principal arm bracing or strutting arrangement of variable-angle of the present invention.
Fig. 5 is the card article structural representation of the car hosit principal arm bracing or strutting arrangement of variable-angle of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is further described.
As shown in Figure 1, Figure 2 and Figure 3, the car hosit principal arm bracing or strutting arrangement of variable-angle of the present invention, is comprised of support platform 1, strut bar base 2, the first strut bar 3, the second strut bar 4, steel cable 6, arm 7, horizontal drive apparatus 15.The first strut bar 3, the second strut bar 4 are two joint hydraulic actuating cylinders, and hydraulic actuating cylinder is connected with strut bar base 2 by hinge by spherical hinge 5 and is connected with arm 7.The first groove 20 of opening in the bottom boss of strut bar base 2 and support platform 1, the second groove 16 coincide mutually.The position of the secondary groove 18 of the first secondary groove 17, second, the 3rd secondary groove 19 in a of support platform 1, b, c position difference corresponding diagram 4, when support platform is pulled to this three positions, card article 22 can be locked through corresponding draw-in groove.When support platform 1 need to move, card article 22 is taken out from corresponding draw-in groove, starting 7 to second draw-in groove positions of horizontal drive apparatus, be loaded on card article 22 and just can.Arm 7 consists of hydraulic actuating cylinder, and suspension hook is connected with steel cable 6, and by two fixed pulley hoisting heavies on arm 7, steel cable 6 circle axle of d in Fig. 1-4 provides propulsive effort by motor.By changing the position of strut bar base, regulate the angle between strut bar and arm, alleviated the stressed of arm heavy duty, hoisting crane Maximum Loading Capacity is increased, the requirement of material is reduced simultaneously.
