Abstract
The invention discloses a self-propelled platform base, which comprises a base, wherein the base is hinged with a swing bridge through a base spindle; wheels are arranged on the two sides of the swing bridge; extension bridges are arranged on the inner sides of the wheels and in the swing bridge and comprise a left extension bridge and a right extension bridge; the wheels include a left wheel and a right wheel; the left extension bridge is arranged on the inner side of the left wheel and the right extension bridge is arranged on the inner side of the right wheel; and the left and right extension bridges are not in the same line. In the invention, as the extension mechanisms of the left and right wheels are not in the same line, wider extension space is formed on the basis of the same base width, and the extended base is wider and more stable, provides a higher strength for supporting an overhead operation platform and lowers tripling possibility; the extension bridge structure can complete extending wheel distance in a running process; the working efficiency is high; and stability and reliability are ensured.
Description
Technical field
The present invention relates to engineering machinery field, relate in particular to a kind of from walking the flat-bed base.
Background technology
Self-propelled high-altitude operation platform is widely used in industries such as Ship Building and Repairing, engineering construction, industry installation, overhaul of the equipments, the ground of these working spaces generally can be not smooth, there are obstacles such as hollow, sloping road and stone, the self-propelled flat-bed base of traditional rigidity cross country power deficiency, adopt four wheel drive still can, as adopt two-wheel drive, then can't use in this place substantially; And overhead distance is too low as base, and then carrying capacity is relatively poor, can't the more place of adjustment disorder thing, and overhead distance is too high, then not enough to the High Altitude Platform bearing force as base, rollover easily takes place and cause accident.
Be to improve the stability of High Altitude Platform, reduce possibility of rollover, need to increase wheelspan, but big wheelspan crossing ability is poor, and the highway up train has maximum wheelspan requirement, therefore need scalable wheelspan, the expansion wheelspan dwindles wheelspan during operation when advancing; A few days ago, most bases adopt and stop under the travel condition, adopt bont that roof is risen certain altitude, make that wheel is liftoff to be stretched again, manually car are put down inefficiency and complex structure again after flexible the putting in place.
The patent No. 200720177872.0 provides a kind of base running gear that is used for the aloft work vehicle, it is flexible that its wheelspan telescoping mechanism can be finished wheelspan in the process of moving automatically, its telescopic oil cylinder is the double piston-rod structure, the telescopic oil cylinder cylinder barrel is fixed on the base, oil cylinder is made and installs complicated, and this base do not adopt the swing axle structure, and the road is not at ordinary times, can have the liftoff unsettled phenomenon of wheel, cause the propulsive effort deficiency.
The patent No. 200820035630 and 200810025198 provides a kind of base that can keep back the self-propelled high-altitude operation platform of pavilion platform in balance automatically, adopt the moving bridge construction of double pendulum, but its three six logical control cock are installed on the back axle, and the control lever and the back axle of control cock are hinged, be difficult to form feedback, action response speed and control accuracy aspect exist not enough, and the flexible jacking cylinder system that also adopts of its wheelspan, complex structure, inefficiency.
The patent No. 201010157914 provides a kind of self-propelled aerial working platform vehicle base, adopts the mechanical hydraulic servo control mechanism to realize that tire and ground servo-actuated guarantee propulsive effort, and can finish the flexible of wheelspan in the process of moving automatically; But this structural control system complexity.
Summary of the invention
The present invention provides a kind of control simple, the self-propelled high-altitude operation platform base that the wheelspan stroke is big for solving the prior art problem.
Technical scheme of the present invention is: a kind of oneself walks platform base, comprises base, is hinged with swing axle by the base main shaft on the base, the swing axle both sides are provided with wheel, the wheel inboard is provided with retractile bridge, and retractile bridge is installed in the swing axle, and retractile bridge comprises left retractile bridge and right retractile bridge; Described wheel comprises left wheel and right wheel, and the left wheel inboard is provided with left retractile bridge, and right wheel inboard is provided with right retractile bridge, and left retractile bridge and right retractile bridge are not on the same straight line.
Left side retractile bridge and right retractile bridge stagger, be not on the same straight line, make the telescopic length of each retractile bridge increase to consistent with the base width by half of original base width, when the High Altitude Platform operation, wideer wheelspan can provide stronger bearing force, make high-altitude operation platform more stable, further reduce the possibility of rollover.
As preferably, described left retractile bridge is arranged at right retractile bridge the place ahead.
As preferably, described left retractile bridge is arranged at right retractile bridge rear.
As preferably, described retractile bridge comprises the retractile bridge chamber, is provided with flexible pontic in the retractile bridge chamber, flexible pontic internal fixation is provided with and expands the bridge hydraulic actuating cylinder, it is external that retractile bridge is stretched out in the piston termination of expansion bridge hydraulic actuating cylinder, peaks at the retractile bridge cavity wall, and be fixed in the retractile bridge cavity wall.
As preferably, described swing axle two ends are provided with steering structure, and described wheel is installed on the steering structure.
The structure of retractile bridge makes that base does not need to promote, and directly just can finish the flexible of wheelspan in traveling process; When wheelspan need enlarge, in self-propelled platform traveling process, independently steering structure made the wheel steering outside, and the piston that expands the bridge hydraulic actuating cylinder begins to stretch out at hydraulic action, and self-propelled platform is advanced forward simultaneously; When wheelspan need dwindle, in self-propelled platform traveling process, independently steering structure made the wheel steering inboard, and the piston that expands the bridge hydraulic actuating cylinder begins in the hydraulic action withdrawal, and self-propelled platform is advanced forward simultaneously.
As preferably, described base both sides are equipped with horizontal hydraulic cylinder, and the bottom-hinged of horizontal hydraulic cylinder is in the base both sides, and the piston of horizontal hydraulic cylinder peaks at the swing axle two ends; Swing axle can rotate around hinge-point under the effect of horizontal hydraulic cylinder.By the swing of horizontal hydraulic cylinder control swing axle, control is simple, carries out the efficient height.
As preferably, the rotating angle of described swing axle is 0～6 degree.
As preferably, be provided with level sensor in the base.By induction base state, the control swing axle is swung to the left or to the right, so that base keeps level all the time.
In sum, the present invention has the following advantages:
1, revolver of the present invention is not on the same straight line with the telescoping mechanism of right wheel, on same base width basis, has wideer extending space, and the base after the stretching, extension is wideer, more firm, and is stronger to the high-altitude operation platform bearing force, the possibility that reduces to turn on one's side;
2, adopt hydraulic actuating cylinder control swing axle, so that wheel and ground servo-actuated keep propulsive effort, speed of response is fast, and the control accuracy height can adapt to different places;
3, the retractile bridge structure can be finished the flexible of wheelspan in the process of moving, and high efficiency is reliable and stable;
4, four wheels all are equipped with independently steering structure, but pivot stud adapts to different places, high efficiency.
