Specific embodiment
Embodiment 1
As shown in figure 1, a kind of electric pushrod drives cab tilting device, mainly include electric pushrod 7 and stop sleeve 9
Two parts, electric pushrod 7 is main by reduction box 7-2, feed screw nut 7-10, leading screw 7-11, retracting cylinder 7-5 and outer sleeve 7-12
Composition.Outer sleeve 7-12 and reduction box 7-2 is fixed as one and is placed on outside retracting cylinder 7-5, one end and the leading screw spiral shell of retracting cylinder 7-5
Female 7-10 is fixedly connected, and the other end of retracting cylinder 7-5 is provided with engaging lug, and retracting cylinder 7-5 is placed on outside leading screw 7-11, the leading screw spiral shell
Female 7-10 and leading screw 7-11 composition screw pairs；Leading screw 7-11 is connected with the output end of reduction box 7-2, and reduction box 7-2's is defeated
Enter end to be connected with power input device；Reduction box 7-2 is provided with the anti-locking mechanism of movement interference with the opposite side that outer sleeve 7-12 is connected,
The anti-locking mechanism of movement interference and retracting cylinder 7-5 are connected with vehicle frame 6 and driver's cabin 1 by pin hinge respectively.
As shown in Fig. 2 being provided with the first-stage worm gear of one-level worm screw 7-7 and first-stage worm gear 7-6 compositions in described reduction box 7-2
Worm gear pair, and the second-stage worm gear worm gear pair that second-stage worm 7-8 and second-stage worm gear 7-9 is constituted；Wherein second-stage worm 7-8 and one-level
Worm gear 7-6 is coaxial and links together, and one-level worm screw 7-7 is the input of reduction box 7-2, and second-stage worm gear 7-9 is reduction box
The output end of 7-2.
The power input device is connected and composed by motor 7-3 and manual speed increasing mechanism with double output shaft, is increased manually
Fast mechanism is interconnected to constitute by manual shaft 7-4, gear train 7-13 and output shaft, manual speed increasing mechanism output shaft and motor 7-3
An output shaft connection.
The anti-locking mechanism of movement interference is by the bottom thick stick 7-1 that is fixed on reduction box 7-2 and the support being placed on outside bottom thick stick 7-1
Sleeve 9 is constituted, and the slotted hole bearing pin 8 on bottom thick stick 7-1 links together bottom thick stick 7-1 and stop sleeve 9, and movement interference is prevented
Mechanism passes through to be provided with engaging lug on stop sleeve 9 or bearing pin 8 is connected on vehicle frame 6.
Electric pushrod drives cab tilting device also including the oil cylinder 4 of unlatching hydraulic lock, and oil cylinder 4 is by screw 5 and subtracts
Fast case 7-2 is fixed together, and when retracting cylinder 7-5 starts protruding, promotes reduction box 7-2 to move downward, the piston of oil cylinder 4
Bar 4-1 will be pushed by plane on stop sleeve 9, and oil cylinder 4 produces pressure oil to open hydraulic lock.
The preferred ball-screws of leading screw 7-11.
The utility model device operation principle is as follows：
The state that driver's cabin does not overturn is represented in Fig. 1, now the retracting cylinder 7-5 of electric pushrod 7 is reduced to most short position, this
When electric pushrod 7 the bottom surface of reduction box 7-2 have apart from S apart from the upper plane of stop sleeve 9, prevent driver's cabin 1 with respect to car
Electric pushrod 7 and vehicle frame 6 are interfered when frame 6 is moved downward；When driver's cabin 1 fluctuates relative to vehicle frame 6, electric pushrod
7 bottoms thick stick 7-1 Shang Chang gardens hole and bearing pin have a gap S/2 about 8, eliminate interfering for electric pushrod 7 and vehicle frame 6, bearing pin 8
Electric pushrod 7 is also prevented to be come off from stop sleeve 9 simultaneously.
When being flipped up driver's cabin 1, retracting cylinder 7-5 start it is protruding, while promote electric pushrod 7 other parts to
Lower motion, when the bottom surface of reduction box 7-2 touches the upper plane of stop sleeve 9, reduction box 7-2 is no longer moved downward, instead
Come over the support telescopic cylinder 7-5 promotions upset clockwise of driver's cabin 1, as shown in Figure 3.
When downwardly turning over driver's cabin 1, retracting cylinder 7-5 is inwardly retracted, and driver's cabin 1 is turned round when in place, and retracting cylinder must continue to
Retract and simultaneously pull up the other parts of electric pushrod 7, when retracting cylinder 7-5 is retracted into minimum position, reduction box 7-2's
Bottom surface is S apart from the distance of the upper plane of stop sleeve 9, completes a cycle process of upset.
Electric pushrod 7 can also be fixedly connected with vehicle frame 6, and driver's cabin 1 is used with the anti-movement interference of Telescopic
And the mechanism's connection for producing pressure oil is attached, or connected using other mechanisms for being avoided that interference.
Bearing pin 8 may replace support shaft 10, will bearing pin 8 make the support shaft that is connected with vehicle frame 6 into, now bearing pin 8 is not only
Connection stop sleeve 9, is also connected with the bottom thick stick 7-1 of electric pushrod 7, reaches shortening driver's cabin 1 and vehicle frame 6 installs electric pushrod 7
Distance, compact conformation.
Two-stage worm transmission can also have the worm and gear of auto-lock function and the transmission mechanism generation of other forms with one-level
Replace, also reach identical effect.
In addition to the implementation, manual speed increasing mechanism can also be arranged between motor 7-3 and reduction box 7-2, with same
Sample effect.
