Ladder described in the utility model technical solution when upper lock position and vertical direction have the interior inclined to one side angle of 10 °.
On side link described in the utility model technical solution, connecting rod, ladder, U-shaped connection base, be equipped with strength beam or piece; Upper limit seat is the back-up block form that has arc surface.
The beneficial effects of the utility model are: HOP ON–HOP OFF, electric pushrod installation and maintenance are convenient, four-bar mechanism is simple and reliable for structure, ladder and Guardrail design has effectively reduced its overall weight, assembly type design dismounting is easy to maintenance.
The utlity model has structure more advantages of simple, get on or off the bus more convenient, produce feature easier for installation, structure is more attractive in appearance.The utility model is mainly used in the apparatus for getting on/down of large-scale mine dumping car.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. guardrail, 2. electric pushrod hinged support, 3. electric pushrod, 4. four-bar mechanism, 5. lower limit seat, 6. ladder, 7.U shape connect base, 8. upper limit seat.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1.The utility model comprises: the electric pushrod hinged support 2 of a side, electric pushrod 3, four-bar mechanism 4, upper approach switch, lower approach switch, the ladder 6 between the guardrail 1 of both sides, lower limit seat 5, upper limit seat 8 and guardrail, U-shaped connect the turnover ladder switch on base 7 and vehicle body side ladder side.The upper fixed end of guardrails of both sides 1 is installed in the upper plane of car body, lower fixed end is installed on the side plane of car body, guardrail 1 adopts the form being directly installed on car body to reduce turnover ladder load and weight, the longeron of ladder adopts the design of welded type strength beam, is guaranteeing to reduce its size and weight when it has enough strength and stiffness as far as possible.It is with bolts on the side plane of 1 time fixed end oblique upper of car body guardrail that U-shaped connects base 7, and hinged with ladder 6 upper ends.Four-bar mechanism 4 comprises that side link, connecting rod, ladder 6 and U-shaped connect base 7, and to be wherein connected base 7 hinged with electric pushrod, connecting rod, U-shaped respectively for side link, and connecting rod and ladder 6 are hinged, and U-shaped connection base 7 and ladder 6 are hinged; Wherein ladder 6 is connected connecting rod and the frame that base 7 serves as respectively four-bar mechanism 4 with U-shaped.Electric pushrod hinged support 2 is welded on car body, and one end of electric pushrod 3 and electric pushrod hinged support 2 are hinged, and the other end and side link are hinged.Thereby by controlling the elongation of electric pushrod and shortening, drive four-bar mechanism to promote spinning upside down of ladder, to reach two utmost point positions of ladder.On car body when upper limit seat 8, lower limit seat 5 correspondences are welded on ladder 6 and are positioned at upper and lower restriction position, upper limit seat 8 is for having the back-up block form of arc surface.The vehicle body side ladder side that turnover ladder switch is arranged in operator's compartment and people conveniently contacts, upper approach switch and lower approach switch are arranged on respectively above the ladder bumper/spoiler that Shang Xia 6, lock position is corresponding, utilize upper and lower stop gear, its failure-free is stopped on desired position, wherein lower limit position guarantees that there are 60 ° of angles on ladder and ground, so that HOP ON–HOP OFF; Upper limit position guarantees that ladder and vertical direction have the interior inclined to one side angle of 10 °, reliable to guarantee its afterwards spacing of overturning up.On side link, connecting rod, ladder, U-shaped connection base, be equipped with strength beam or piece.
When ladder 6 is during in lower utmost point position, turnover ladder switch to be got to upper, electric pushrod 3 extends and drives four-bar mechanisms 4, makes to turn on ladder 6; When reaching upper limit seat 8 and place restrictions on, be contained in upper approach switch above bumper/spoiler and detect that the power-off of ladder position stops and locking relatively; When ladder is during in upper utmost point position, turnover ladder switch is got to the next, electric pushrod shorten to drive four-bar mechanism 4, and ladder is turned over for 6 times, when reaching lower limit seat 5 and place restrictions on, the lower approach switch that is contained in bumper/spoiler side detects that the power-off of ladder position stops and locking relatively.
The foregoing is only the utility model preferred embodiment; not in order to limit the utility model; not thereby limit claim of the present utility model; so the equivalent structure that all utilization the utility model specification sheetss and diagramatic content are made changes, and is all included in protection domain of the present utility model.
