Abstract
The invention discloses a folding type lifting rack, belonging to the technical field of lifting equipment. A bracket and an electric spiral push rod are respectively fixedly installed at the upside of a base; one end of a swinging arm is hinged with the bracket; one end of a driving arm is hinged at the middle part or middle position of the swinging arm, and the other end of the driving arm is hinged with a lead screw of the electric spiral push rod; short connecting rods and long connecting rods are hinged with one another, forming a parallelogram mechanisms, wherein the swinging arm serves as one side of the parallelogram mechanism at the lowest end; and two ends of an actuating joint are respectively hinged with the driving arm and the end part of the protruded end of the long connecting rod of the parallelogram mechanism at the lowest end, forming a whole parallelogram mechanism. The folding type lifting rack has the advantages of simple structure, low cost, convenient usage and small volume and is applicable in occasions in which lifting tools are used often in production, rescue, outdoor advertisement and other fields.
Description
Technical field
The present invention relates to a kind of rising frame, specifically refer to a kind of can folding rising frame, 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 high-altitude rescue; Setting up of high altitude firefighting water pipe; Large-scale outdoor advertising; High-altitude illumination etc.All need lift apparatus.At present, temporary without 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 purpose, because the height that these instruments can reach is limited, comparatively bother in using in addition, so the scope of its use is subject to certain restrictions, especially be not suitable for the use in higher spatial domain.In the aloft work of some, although 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 object of the invention is to: a kind of foldable lifting support is provided, and convenient use in some high field institute simultaneously, also is to have some lift apparatus existing defects in above-mentioned place now in order to overcome.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: this foldable lifting support comprises base, swing arm, actuating arm, driving joint, short connecting rod, long connecting rod, the electric screw push rod, support, it is characterized in that: described base is the basis of installation and the support of whole device, 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 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, be hinged into parallel-crank mechanism between short connecting rod and the long connecting rod, wherein swing arm forms wherein one side of a parallel-crank mechanism bottom, the two ends of driving joint are hinged with 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 present invention is because directly by short connecting rod, the long connecting rod place's parallel-crank mechanism that is hinged, the stretching, extension of mechanism is controlled by the electric screw push rod with recovery, the present invention not only has simple in structure, and cost is lower, and is easy to use, the advantage of small volume, so, can extensively be adapted to production, rescue, outdoor advertising and some other field, often to use the place needs of rising instrument, simultaneously, also can overcome existing lift apparatus defective in the above use.
Description of drawings
Accompanying drawing is structure principle chart of the present invention;
Shown in the figure: 1, base; 2, swing arm; 3, actuating arm; 4, driving joint; 5, short connecting rod; 6, long connecting rod; 7; The electric screw push rod; 8, support.
The specific embodiment
In the drawings, this foldable lifting support comprises base 1, swing arm 2, actuating arm 3, driving joint 4, short connecting rod 5, long connecting rod 6, electric screw push rod 7, support 8, the described metallic material of some strength of selecting is made respectively short connecting rod 5 and long connecting rod 6, base 1 is the basis of installation and the support of whole device, 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 middle part or the midway location of swing arm 2, an other end of actuating arm 3 and the leading screw of electric screw push rod 7 are hinged, be hinged into parallel-crank mechanism between short connecting rod 5 and the long connecting rod 6, wherein, swing arm 2 forms wherein one side of a parallel-crank mechanism bottom, the two ends of driving joint 4 are hinged with 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.
