Abstract
The invention discloses a novel foldable lifting frame. A fixing support frame and a hydraulic cylinder are enabled to be installed on a base seat, one end of a swinging arm is connected with the support frame in a hinged mode, one end of a drive arm is connected with the middle or the middle position of the swing arm in a hinged mode, the other end of the drive arm is connected with a piston rod of the hydraulic cylinder in a hinged mode, short connecting rods and long connecting rods are mutually connected to form parallelogram mechanisms in a hinged mode, wherein the swing arm serves as one side of the parallelogram mechanism on the bottom, two ends of a drive joint are connected with the end portion of one end, protruding out, of the long connecting rod of the parallelogram mechanism at the bottom and the drive arm in a hinged mode so as to form one intact parallelogram mechanism.
Description
Technical field
The present invention relates to a kind of rising frame, particularly a kind of novel 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 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, be exactly generally 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 novel folding rising frame is provided, and convenient use in some high field institute simultaneously, is also 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: a kind of novel folding rising frame, it is by base, swing arm, actuating arm, driving joint, short connecting rod, long connecting rod, hydraulic actuating cylinder, and support forms, it is characterized in that: base is the basis of installation and the support of whole device, difference mounting and fixing bracket and hydraulic actuating cylinder above 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 piston rod of hydraulic actuating cylinder are hinged, be hinged into parallel-crank mechanism between short connecting rod and 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 due to directly by short connecting rod, the long connecting rod place's parallel-crank mechanism that is hinged, the stretching, extension of mechanism and recovery have hydraulic actuating cylinder to control, 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 figure: 1, base; 2, swing arm; 3, actuating arm; 4, driving joint; 5, short connecting rod; 6, long connecting rod; 7, hydraulic actuating cylinder; 8, support.
The specific embodiment
select the metallic material of some strength to make 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 and fixing bracket (8) and hydraulic actuating cylinder (7) above base (1), one end of swing arm (2) and support (8) 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 piston rod of hydraulic actuating cylinder (7) are hinged, be hinged into parallel-crank mechanism between short connecting rod (5) and 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.
Claims (1)
1. novel folding rising frame, it is characterized in that: difference mounting and fixing bracket (8) and hydraulic actuating cylinder (7) on base (1), one end of swing arm (2) and support (8) 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 piston rod of hydraulic actuating cylinder (7) are hinged, be hinged into parallel-crank mechanism between short connecting rod (5) and 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.
