Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of specification sheets, and for above and other objects of the present invention, feature and advantage can be become apparent, below especially exemplified by embodiment, and the cooperation accompanying drawing, be described in detail as follows.
Description of drawings
Fig. 1 is the structural representation of the working bucket guardrail of preferred embodiment aerial platform of the present invention.
Fig. 2 is the structural representation of another state of the working bucket guardrail of preferred embodiment aerial platform of the present invention.
Fig. 3 is the cross section structure scheme drawing at Ш among Fig. 1-Ш place.
The specific embodiment
Reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, to the aerial platform of foundation the present invention proposition and the specific embodiment, structure, feature and the effect thereof of working bucket guardrail thereof, be described in detail as follows:
Relevant aforementioned and other technology contents of the present invention, Characteristic can be known to present in the following detailed description that cooperates with reference to graphic preferred embodiment.By the explanation of the specific embodiment, when can being to reach technological means and the effect that predetermined purpose takes to be able to more deeply and concrete understanding to the present invention, yet appended graphic only provide with reference to the usefulness of explanation, the present invention is limited.
See also illustrated in figures 1 and 2ly, the aerial platform of working bucket guardrail 1 of using the aerial platform of preferred embodiment of the present invention comprises working bucket 2, jib 3, and other parts such as car body.
Working bucket 2 is " bucket " shape, comprises base 20, and is arranged on the guardrail 22 around the base 20.Working bucket 2 is one side lower part and joint arm 32 terminal hinged that is in jib 3 ends.Usually, aerial platform also comprises the working bucket balancing device, so that working bucket 2 remains on the balance position of level relatively.
Sliding part 14 is embedded in the chute 122 of guide rail 12, and can slide along chute 122.In the present embodiment, sliding part 14 is slide blocks, interior the scalding of sliding part 14 nuts 142 is arranged, and namely nut 142 is fixed in the sliding part 14 by methods such as hot melts.Bearing pin 104 is established a threaded end and is captiveed joint with nut 142 by screw thread fit.
In the present embodiment, the grab rail 10 of guardrail 1, guide rail 12, and sliding part 14 is paired setting.That is, pair of armrests bar 10 is arranged on the both sides of working bucket 2 one sides, the both sides of its sluice gate (not shown) for example, and pair of guide rails 12 is arranged on the joint arm 32 and attached terraced 34 adjacent both sides.The bending place of grab rail 10 is towards working bucket 2 tops.
Like this, when the jib 3 of aerial platform was in folding state, joint arm 32 was in horizontality (referring to Fig. 1) substantially, and the angle between joint arm 32 front ends and the working bucket 2 is minimum.Along with the rising of jib 3, change angle increases, because working bucket 2 remains level, working bucket 2 increases with the angle of joint arm 32 front ends.Grab rail 10 and working bucket 2 hinged first ends rotate relative to working bucket 2, and grab rail 10 and sliding part 14 the second hinged end relative sliding spares 14 rotate, simultaneously sliding part 14 the chute 122 of guide rail 12 in towards the slip of joint arm 32 front ends.Until the change angle of jib 3 reaches maximum, i.e. as shown in Figure 2 state.
Like this, the aerial platform and the working bucket guardrail thereof that adopt the present invention to propose, no matter which kind of state is working bucket 2 be in jib 3, and grab rail 10 all is connected between the two, thereby protects and armrest positions for the occupant provides.And sliding part 14 is concealed in the guide rail 12, and the sliding surface of guide rail 12 also is in guide rail 12 inboards, and its degree of finish can be protected by actv., is not vulnerable to extraneous destruction from the process that is fabricated onto use.Can also annotate easily and store lubricating grease in that guide rail 12 is interior.
Be appreciated that sliding part 14 can not be slide block in other embodiment of the working bucket guardrail of the aerial platform that the present invention proposes, but roller.Establish a threaded end by nut 142 and bearing pin 104 equally and be fixed together by screw thread fit, namely served as the rotating shaft of roller by bearing pin 104.Thereby further reduce the friction force of relative motion, make the slip of sliding part 14 more smooth and easy.In addition, sliding part 14 also can be integral with bearing pin 104.Be appreciated that equally at grab rail 10 and sliding part 14 the second hinged ends also spherical plain bearing rod end 102 not to be set, and common bearing is set, can reach technique effect of the present invention equally.
The above, only be embodiments of the invention, be not that the present invention is done any pro forma restriction, although the present invention discloses as above with embodiment, yet be not to limit the present invention, any those skilled in the art, within not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solution of the present invention content, any simple modification that foundation technical spirit of the present invention is done above embodiment, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
