Abstract
The utility model discloses a foldable lifting support, which belongs to the technical field of lifting devices. A support and an electric spiral push rod are respectively and fixedly installed above a base, one end of a swinging arm is hinged to the support, one end of an actuating arm is hinged to the middle part of the swinging arm or a middle position of the swinging arm, the other end of the actuating arm is hinged to a lead screw of the electric spiral push rod, short connecting rods and long connecting rods are hinged to each other to form parallelogram mechanisms, wherein the swinging arm serves as one side of the parallelogram mechanism at the lowest end. Two ends of an actuating joint are respectively hinged to an end portion of the protruding end of the long connecting rod of the parallelogram mechanism at the lowest end and the actuating arm to form a complete parallelogram mechanism. The foldable lifting support has the advantages of being simple in structure, low in cost, convenient to use, small in volume and capable of being suitable for production, rescuing, outdoor advertising and other fields which need to use lifting tools frequently.
Description
Technical field
The utility model relates to a kind of rising support, specifically be meant a kind of can collapsible rising support, belong to the lift apparatus technical field.
Background technology
In production, rescue, outdoor advertising and some other field, often to use lift apparatus, such as: access goods from high-rise; Manned, provisions in the rescue of high-altitude; Setting up of high-altitude fire pipes; Large-scale outdoor advertising; High-altitude illumination or the like.All need lift apparatus.At present, temporary no special lift apparatus in above-mentioned field, so; In order to reach the purpose of rising, generally be exactly to adopt the rod member of common ladder, lengthening to reach corresponding target, because the height that these instruments can reach is limited; Comparatively bother in using in addition; So the scope of its use receives certain restriction, the especially not use in suitable higher spatial domain.In the aloft work of some, though also can use the telescopic boom hydraulic lift,, this equipment not only use cost is higher, simultaneously, because its volume is general also huger, also not too adapts in less space.
Summary of the invention
The purpose of the utility model is: a kind of collapsible rising support is provided, and convenient use in some higher places simultaneously, also is in order to overcome more existing lift apparatus existing above-mentioned defective in above-mentioned place.
The utility model realizes that the technical scheme that above-mentioned purpose adopted is: this collapsible rising support comprises base, swing arm, actuating arm, driving joint, short connecting rod, long connecting rod, electric screw push rod, support; It is characterized in that: said base is the basis of whole Unit Installation and support; Difference mounting bracket and electric screw push rod above the base; One end and the support of swing arm are hinged; One end of actuating arm is hinged on the middle part or the midway location of swing arm; An other end of actuating arm and the leading screw of electric screw push rod are hinged, and are hinged into parallel-crank mechanism between short connecting rod and the long connecting rod, wherein swing arm form bottom a parallel-crank mechanism wherein on one side; The two ends that drive the joint are hinged with the end and the actuating arm of protrusion one end of the long connecting rod of bottom a parallel-crank mechanism respectively, also form complete parallel-crank mechanism between them.
Beneficial effect: the utility model is because directly by short connecting rod, the long connecting rod place's parallel-crank mechanism that is hinged, the stretching, extension of mechanism with reclaim by the control of electric screw push rod, the utility model not only has simple in structure; Cost is lower, and is easy to use, the advantage that volume is less; So the ability suit often will use the field of rising instrument required in production, rescue, outdoor advertising and some other field; Simultaneously, also can overcome the existing defective of lift apparatus in above-mentioned use.
Description of drawings
Accompanying drawing is the structure principle chart of the utility model;
Shown in the figure: 1, base; 2, swing arm; 3, actuating arm; 4, drive the joint; 5, short connecting rod; 6, long connecting rod; 7; The electric screw push rod; 8, support.
The specific embodiment
In the drawings; This collapsible rising support comprises base 1, swing arm 2, actuating arm 3, drives joint 4, short connecting rod 5, long connecting rod 6, electric screw push rod 7, support 8; The said metal material in certain strength of selecting for use is made short connecting rod 5 and long connecting rod 6 respectively, and base 1 is the basis of whole Unit Installation and support, difference mounting bracket 8 and electric screw push rod 7 above the base 1; One end and the support 8 of swing arm 2 are hinged; One end of actuating arm 3 is hinged on the middle part or the midway location of swing arm 2, and an other end of actuating arm 3 and the leading screw of electric screw push rod 7 are hinged, and is hinged into parallel-crank mechanism between short connecting rod 5 and the long connecting rod 6; Wherein, Swing arm 2 form bottom a parallel-crank mechanism wherein on one side, the two ends that drive joint 4 are hinged with the end and the actuating arm 3 of protrusion one end of the long connecting rod 5 of bottom a parallel-crank mechanism respectively, also form complete parallel-crank mechanism between them.
