Abstract
The utility model design a folding crane which mainly comprises a base, an upright column and a boom, wherein the upright column is arranged on the base, two supporting rods are arranged on the base by hinge pins and are connected with the upright column by the hinge pins, and acute angles are formed between each supporting rod and the upright column, the upright column and the boom are rotatably connected by a hinge pin, a cylinder is arranged on the upright column by hinge pin connection, the other end of the cylinder is connected with the boom by a hinge pin, a boom extension bar is arranged inside the boom, and a hook is arranged at the outmost end of the boom extension bar. All parts of the folding crane are connected by the hinge pins so as to be convenient for disassembly, and the crane can be folded when not used so as to reduce the occupied space. Six universal wheels are arranged on the base so as to be convenient for moving the folding crane in the using and non-using process. Meantime, the boom and the boom extension bar are provided with limiting holes so as to limit the boom extension bar. In addition, the boom is provided with reinforcing plates so as to improve the bearing performance of the boom.
Description
Technical field
The utility model relates to the mechanical equipment field, especially a kind of foldable crane.
Background technology
Present small-sized loop wheel machine on the market all is through screw or electric welding support to be fixed; Such loop wheel machine will take a large amount of spaces under obsolete situation; And can't pass through at some narrow relatively doors or passageways, make its field of employment receive certain restriction.Existing in addition this loop wheel machine can't can only be changed part exchanging with global facility when certain part is damaged therein, has so just caused the waste of resource, and can bring unnecessary trouble.
The utility model content
The purpose of the utility model is to provide a kind of easy to use for the deficiency that solves above-mentioned technology, has the folding foldable crane of placing function.
In order to achieve the above object, the utility model institute design-calculated foldable crane, it mainly comprises base, column and arm; Base is provided with column; Simultaneously on base, be provided with two strut bars, be connected through bearing pin between two strut bars and the column and form acute angle in twos, be rotatably connected through bearing pin between column and the arm through bearing pin; On column, be connected with cylinder through bearing pin; The other end of cylinder is connected through bearing pin with arm, in the arm set inside arm extension bar is arranged, and is provided with hook in the outermost end of arm extension bar.Such structure is connected firmly, and the dismounting folding convenient.
Described base is made up of bottom bar, cross bar and two foot levers; Bottom bar is connected with an end of two foot levers; Cross bar is captiveed joint with two foot levers; Four bars are inner to be formed trapezoidally, is respectively arranged with cardan wheel at the two ends of bottom bar and cross bar, also is provided with cardan wheel in the side away from cross bar of every foot lever.Such structural materials is used few, sound construction, and convenient moving.
The back side in arm and cylinder junction is provided with back-up block, is provided with the brace panel of captiveing joint with the arm two ends in the back-up block upper end.Can increase the fastness of arm like this, make the load-bearing of arm bigger.
On arm and arm extension bar, be provided with cooresponding spacing hole.Like this can be spacing to the arm extension bar, prevent in use to be moved, cause the accident.
The resulting foldable crane of the utility model all connects through bearing pin between its each parts, convenient disassembly, and can under obsolete situation, it be folded up, reduce its occupation space.Simultaneously such loop wheel machine can make the scope of its field of employment wider through some narrow relatively door or passageways.Base is provided with six cardan wheels, makes things convenient for foldable crane moving in use or not use.Simultaneously its arm extension bar the operating range that can increase loop wheel machine is set, also be provided with spacing hole, can be spacing to the arm extension bar.Arm is provided with brace panel in addition, can increase the weight capacity of arm.
Description of drawings
Fig. 1 is the structural representation of the utility model.
