Abstract
The utility model discloses an adjustable suspension arm assembly comprising a hoisting ring, a connecting rod, a left suspension arm and a right suspension arm, wherein the lower end of the connecting rod is movably connected with the upper ends of the left and the right suspension arms; after being unfolded, the left and the right suspension arms are herringbone; the lower ends of the left and the right suspension arms are fixed on the left and the right ends of the cross rod respectively; vertical gripper arms are also arranged at the left and the right ends of the cross rod; each suspension arm is formed by connecting an upper arm with a lower arm; through holes are formed in the connecting parts of the upper and the lower arms; and the upper and the lower arms are connected with each other through a bolt penetrating the through holes. Through the arrangement of the through holes, the adjustable suspension arm assembly has the advantages that the lengths of the suspension arms, the cross rod and the vertical gripper arms are adjustable; the replacement is convenient; and the practicability is higher.
Description
Technical field
The utility model relates to a kind of adjustable boom assembly, belongs to the lifting appliance field.
Background technology
Arm, the cross bar of tradition lifting appliance, the length of gripping arm are fixed, and can not regulate the opening angle of arm as required, also can not be according to the particular case of suspended object, and under the situation of arm failsafety, can not change.
The utility model content
For solving the problems of the technologies described above, the adjustable boom assembly that the utility model provides comprises suspension ring, connecting rod and left and right sides arm, and the upper end of the lower end of said connecting rod and said left and right sides arm flexibly connects, and said left and right sides arm launches to be chevron pointing; The lower end of said left and right sides arm is separately fixed at the right ends of cross bar, and the right ends of said cross bar also is provided with vertical gripping arm.Said left and right sides arm is formed by connecting by upper arm and underarm, is provided with through hole at the connecting bridge of said upper arm and underarm, and screw passes said through hole upper arm and underarm are coupled together.
Said cross bar is formed by connecting on left bar and right bar, and the connecting bridge of bar is provided with through hole in the said left and right sides, and screw passes this through hole left bar and right bar are coupled together.
Said vertical gripping arm is formed by connecting last gripping arm and following gripping arm, is provided with through hole at the said connecting bridge of gripping arm up and down, and screw passes that this through hole will be gone up gripping arm and following gripping arm couples together.
Saidly go up underarm, left and right sides bar, the number of through hole is 8 in the gripping arm up and down, respectively along saidly go up underarm, left and right sides bar, that gripping arm divides two rows up and down is vertically evenly distributed.
The pore size of said through hole is identical.
Arm is divided into underarm and is used in be respectively arranged with an exhausting hole on the underarm, connect and go up underarm thereby pass through hole through screw, make the adjustable length of arm, in like manner the length of cross bar, gripping arm is also adjustable, is convenient for changing, and is also practical more.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in the figure, the utility model comprises suspension ring 1, connecting rod 2 and left and right sides arm 3, and the upper end of the lower end of said connecting rod 2 and said left and right sides arm 3 flexibly connects, and said left and right sides arm 3 launches to be chevron pointing; The lower end of said left and right sides arm 3 is separately fixed at the right ends of cross bar 5, and the right ends of said cross bar 5 also is provided with vertical gripping arm 6.Said left and right sides arm 3 is formed by connecting by upper arm 3a and underarm 3b, is provided with through hole 4 at the connecting bridge of said upper arm 3a and underarm 3b, and screw passes said through hole 4 upper arm 3a and underarm 3b are coupled together.The number of said through hole 4 is 8, divides two rows vertically evenly distributed along said upward underarm 3a, 3b respectively, the equal and opposite in direction of said through hole 4.When needs are regulated the length of left and right sides arm 3, pull down screw, with the relative position of last underarm 3a, 3b near, and then pass cooresponding through hole 4 with screw
Left and right sides arm 3 is fixing.In like manner, cross bar 5, vertical gripping arm 6 also are provided with through hole, thereby realize its adjustable length.
The above is merely the preferred embodiment of the utility model, not in order to restriction the utility model, any modification of being done within all spirit at the utility model and the principle, is equal to and replaces and improvement etc., all should be included in the protection domain of the utility model.
