Description
Technical field
The utility model relates to a kind of bearing set, belongs to aerial platform safety method field, especially a kind of aerial platform hydraulic pressure secondary support means.
Background technology
At present, the aerial platform of being used always on the market all is provided with two pairs of supporting legs, lays respectively at the middle part and the afterbody of chassis.When implementing operation, two pairs of supporting legs are propped car load, make the wheel built on stilts.At this moment, the front portion of two longerons of chassis vehicle frame becomes cantilever beam; The influence of the vibration that produces under the action of gravity of operator's compartment, driving engine etc. and when receiving engine operation, two longerons are easy to take place fracture by fatigue.In addition, the action of gravity of operator's compartment, driving engine etc. forms the destabilizing moment that car load is tumbled forward at the front end of two longerons, makes the operating range of jib reduce, the operational security variation.
Summary of the invention
The purpose of the utility model is the problem that exists to above-mentioned prior art; A kind of aerial platform hydraulic pressure secondary support means is provided, and this device adopts hydraulic driving mode, increases a pair of auxiliary supporting leg at the front end of aerial platform; Make it in operation process, avoid operator's compartment and driving engine to be hanging shape; Prevent the fracture by fatigue of chassis side rail, improved job safety stability, can effectively enlarge the operating range of jib.
The utility model is realized through following technical scheme: a kind of aerial platform hydraulic pressure secondary support means comprises left feet, left branch leg cylinder, left hydraulic lock, left bracing frame, left connecting panel, fixed mount, right connecting panel, right bracing frame, right hydraulic lock, right supporting leg cylinder, right feet; It is characterized in that: fixed mount is for to be bent into the channel-section steel that Open Side Down by steel plate; The top of fixed mount is welded with L-shaped left connecting panel and right connecting panel, and left connecting panel and right connecting panel are fixedly linked with the left longeron and the right vertical beam of chassis vehicle frame respectively through bolt; Left side bracing frame and right bracing frame are all for being bent into the channel-section steel that opening makes progress by steel plate, the upper end and the fixed mount of left bracing frame and right bracing frame are hinged and connected, and the lower end of left bracing frame and right bracing frame is hinged with left feet and right feet respectively; On left branch leg cylinder and the right supporting leg cylinder left hydraulic lock and right hydraulic lock are housed fixedly respectively; The left and right two ends of the cylinder bottom of left branch leg cylinder and right supporting leg cylinder and fixed mount are hinged and connected; Bottom at left branch leg cylinder and right supporting leg cylinder is respectively equipped with piston rod, and piston rod then is hinged and connected with the lower end of left bracing frame and right bracing frame respectively.
The beneficial effect of the utility model is: adopt hydraulic way to drive bracing frame and pack up and put down; And implement locking by hydraulic lock and locate, neither influence the cruising of aerial platform, can effectively improve job safety stability again; Enlarge the operating range of jib, prevent the fracture by fatigue of chassis side rail.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Among Fig. 1: 1, left feet, 2, the left branch leg cylinder, 3, left hydraulic lock, 4, left bracing frame, 5, left connecting panel; 6, left longeron, 7, fixed mount, 8, right vertical beam, 9, right connecting panel, 10, right bracing frame; 11, right hydraulic lock, 12, right supporting leg cylinder, 13, piston rod, 14, right feet.
The specific embodiment
As shown in Figure 1, the utility model comprises left feet 1, left branch leg cylinder 2, left hydraulic lock 3, left bracing frame 4, left connecting panel 5, fixed mount 7, right connecting panel 9, right bracing frame 10, right hydraulic lock 11, right supporting leg cylinder 12, right feet 14; Fixed mount 7 is for to be bent into the channel-section steel that Open Side Down by steel plate; The top of fixed mount 7 is welded with L-shaped left connecting panel 5 and right connecting panel 9, and left connecting panel 5 and right connecting panel 9 are fixedly linked with right vertical beam 8 with the left longeron 6 of chassis vehicle frame respectively through bolt; All for be bent into the channel-section steel that opening makes progress by steel plate, the upper end and the fixed mount 7 of left bracing frame 4 and right bracing frame 10 are hinged and connected for left side bracing frame 4 and right bracing frame 10, and the lower end of left bracing frame 4 and right bracing frame 10 is hinged with left feet 1 and right feet 14 respectively; Left hydraulic lock 3 and right hydraulic lock 11 fixedly are housed respectively on left branch leg cylinder 2 and right supporting leg cylinder 12; The cylinder bottom of left branch leg cylinder 2 and right supporting leg cylinder 12 and the left and right two ends of fixed mount 7 are hinged and connected; Bottom at left branch leg cylinder 2 and right supporting leg cylinder 10 is respectively equipped with piston rod 13, and 13 in piston rod is hinged and connected with the lower end of left bracing frame 4 and right bracing frame 10 respectively.
Its working process is: when aerial platform goes; Hydraulic oil gets into the loculus of left branch leg cylinder 2 and right supporting leg cylinder 12; Make piston rod retract to the end, left bracing frame 4 is mentioned with right bracing frame 10, make left feet 1 and right feet 14 built on stilts; And implement locking by left hydraulic lock 3 with right hydraulic lock 11 and locate, prevent to fall voluntarily with right bracing frame 10 because of the vibration that produces in going makes left bracing frame 4.When the aerial platform operation; Hydraulic oil gets into the big chamber of left branch leg cylinder 2 and right supporting leg cylinder 12; Piston rod 13 is all stretched out, left bracing frame 4 is put down with right bracing frame 10, left feet 1 and right feet 14 are supported on the ground; And implement locking by left hydraulic lock 3 with right hydraulic lock 11 and locate, prevent that left bracing frame 4 and right bracing frame 10 from soft leg phenomenon taking place.
