Abstract
The utility model discloses a scissors type lifting platform arm support mechanism, comprising an arm support structure and a frame structure, wherein the arm support structure is hinged on the frame structure by a connection device, the wear at the hinge position of the arm support and the frame is reduced, the stability and wear resistance of the scissors type lifting platform arm support mechanism are increased, thus the aloft work efficiency is higher, safer and has more ensure.
Description
Technical field
The utility model relates to a kind of Aerial Work LT, particularly a kind of Aerial Work LT beam mechanism.
Background technology
Aerial Work LT is broad-spectrum aloft work specialized equipment.Its scissor-type physical construction has higher steadiness after bay-lift is hoisted, and roomy job platform and advantages of high bearing capacity make aloft work wider, and is fit to many people operations simultaneously.Existing beam mechanism generally adopts the connection mode of bearing pin or bolt, though cost is lower, long-term frequent operation or goods overload can cause the wearing and tearing of bearing pin or bolt and the distortion of jib.
The utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of steadiness and resistance to abrasion height, and repair demolition is the Aerial Work LT beam mechanism easily.
For achieving the above object, the technical solution of the utility model is: a kind of Aerial Work LT beam mechanism, the framing structure, connecting device and the jacking system that comprise two groups of jib structures, be complementary with described jib structure specification, described jib structure comprise at least two by the hinged jib of jib connecting device; Described framed structure comprises at least two by the hinged framework of framework connecting device; Described framework comprises both sides frame and the fixed sturcture that supports described frame; Described jacking system two ends are fixed on the fixed sturcture of described adjacent frame; Described jib structure by described connecting device cross-articulation in described frame both sides; Described connecting device comprises rotating shaft, be assemblied in the bearing carrier ring in the described rotating shaft and be assemblied in bearing on the described bearing carrier ring; Position, described jib stage casing is provided with the jib hinge hole that is complementary with described connecting device; Frame center section part position, described framework both sides is provided with the framework hinge hole that is complementary with described connecting device.
Adopt the beneficial effect of the technical program to be: the jib of Aerial Work LT adopts bearing to be connected the connection of replacement bearing pin with the framework junction, has reduced wearing and tearing, has increased stability and fluency when the stretching, extension of Aerial Work LT beam mechanism is folding.

The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As illustrated in fig. 1 and 2, front view and lateral plan for the utility model beam mechanism, jib structure comprises two by the hinged jib 1 of jib articulated mounting 3, framed structure comprises two by the hinged framework 2 of framework articulated mounting 4, and described jib structure is articulated in described framed structure frame both sides by connecting device 5.Jacking system 6 one ends are fixed on the adapter plate of described one of them framework of framed structure, and the other end is fixed on the adjacent frame adapter plate with described framework,
As shown in Figure 3, be the constructional drawing of the utility model connecting device, described connecting device comprises a rotating shaft 51, be assemblied in the bearing carrier ring 52 in the described rotating shaft and be assemblied in bearing 53 on the described bearing carrier ring; Be provided with the jib hinge hole 11 that is complementary with described connecting device at position, jib stage casing, be provided with framework hinge hole I 21 and framework hinge hole II 22 at the position, stage casing of framework border.
As shown in Figure 4, work system figure for the utility model beam mechanism, described utility model work system comprises a beam mechanism, a bench board 7 that is arranged on described beam mechanism top, a chassis 8 that is arranged on described beam mechanism bottom, be used for four of the total system migration and move wheel 9, support four supporting legs 10 and the electric system of total system, work system as shown in FIG. comprises three beam mechanisms that link together.
When whole Aerial Work LT system starts working, the motion of the flexible drive adjacent frame of jacking system hydraulic cylinder piston, adjacent frame is formed a working cell, and three working cells drive synchronous working by same hydraulic efficiency pressure system.Work by electric system modulated pressure cylinder.Described beam mechanism quantity can be adjusted according to concrete job requirement.
Adopt the beneficial effect of the technical program to be: to replace the bearing pin connecting device to reduce the wearing and tearing of jib structure and framed structure hinged place by adopting the bearing connecting device, help improving the steadiness of whole Aerial Work LT beam mechanism and the fluency of lifting.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
