Abstract
The utility model relates to a rear end automatic regulating device for a push type stabilizing soil spreader, which is characterized in that a T-slot (10) and a T-shaped strip (15) matched with the T-slot (10) are arranged between a middle connecting rack (4) and an adjusting rack (5); the upper end of an oil cylinder (2) is fixed on the middle connecting rack (4), and the lower end of the oil cylinder is fixed with the adjusting rack (5). The adjusting rack (5) is connected with a push back rack (6) through a cross pin (7). In the paving process, the push back rack (6) drives a spreader (3) go forward through the rear end automatic regulating device; a sensor of a leveling instrument (9) feeds back rugged signal of the ground to a control system, and then a command is sent out by the control system to control the telescoping of the oil cylinder (2) to drive the T-slot (10) or the T-shaped strip (15) of corresponding to a frame, of the middle connecting rack, to slide up and down, and thereby, the high-low position of the rear end of the spreader can be adjusted at any time to ensure the planeness of the paved road and simplify the set process of the initial work state of the spreader.
Description
Technical field
The utility model relates to a kind of road pavement machinery, particularly pushing-type stabilized soil paver rear end automatic regulating apparatus.
Background technology
The most sensor-type Automatic Levelling instrument that are provided with in length and breadth that adopt of the road surface material paver of domestic production at present, use, vertical levelling instrument control paving thickness, cross levelling instrument control transverse slope.This structure can satisfy instructions for use substantially to the self-propelled paver, but for paver, the height of rear end relies on promotion machinery to control elevation, and lets out in these mechanical ubiquities control oil cylinders, the situation that frame is glided gradually makes paving layer thickness more and more lower.For overcoming this situation, will be in operation constantly by manually promoting and adjusting, so accuracy is relatively poor, the planeness on the road surface, back that paves is relatively poor, directly influences construction quality.Also have plenty of on this kind equipment to adopt and manually reinforce locked or positioner prevents to let out in the oil cylinder, but this way once can not finish when initial setting up, then uncontrollable to instantaneous variation in particular cases.
The content of utility model
The technical problems to be solved in the utility model is the deficiency that exists in the existing same category of device for overcoming, and provide a kind of paver rear end that makes that paving layer thickness is adjusted in good time, guarantee the pushing-type stabilized soil paver rear end automatic mechanism of paving layer planeness.
Technological improvement of the present utility model is:
The T shape bar that is provided with T-slot and is mated between middle connection frame and the adjustment rack joins on the frame during the oil cylinder upper end is fixed on, and oil cylinder lower end and adjustment rack are fixed.
Further technological improvement of the present utility model is:
Adjustment rack is connected with the pusher frame by lateral pin.Middle connection frame is connected with paver with centrepin by bearing pin.Centrepin is fixed with levelling instrument support.
The good effect that the utility model produced is: because this device is connected with T shape bar by T-slot between middle frame and the adjustment rack, add the design of upper cylinder, the sensor of levelling instrument is contacted with the road surface reference line, when the frame rear end reaction is downslide, sensor is given the longitudinal gradient instrument with signal feedback, can oil cylinder be promoted by control system, drive frame rear end simultaneously and promote simultaneously; Otherwise frame rear end is descended, thereby can guarantee the planeness of paving layer well, and then improve the integral construction quality.

The vertical view of Fig. 3: Fig. 1.
Fig. 4: the partial enlarged drawing among Fig. 2.
The specific embodiment
As shown in Figure 1 and Figure 2, the utlity model has a frame 12 and middle frame 4, it is the deep-slotted chip breaker 1 of radius that the both sides of middle frame 4 vertically are provided with centrepin 8, and all has a semidiameter between two adjacent deep-slotted chip breakers 1.All cross-under has bearing pin in each deep-slotted chip breaker 1, and by this bearing pin paver 3 is connected with middle frame 4, becomes as a whole.Pusher frame 6 links to each other with adjustment rack 5 by lateral pin 7, and this two large divisions connects by T shape.Also having an oil cylinder 2 in this device, fixedlys connected with middle frame 4 in the seat of honour 13 of this oil cylinder 2, and following 14 is fixed on the adjustment rack 5.Be connected with the locker 11 that constitutes with screw rod and block in the upper end of frame 12 and pusher frame 6.
As shown in Figure 3, Figure 4, also vertically be provided with T-slot 10 and T shape bar 15 between middle frame 4 and adjustment rack 5, the two is slidingly matched.Levelling instrument support 9 is fixed on the centrepin 8, is connected with the levelling instrument on the levelling instrument support 9.
The course of work of the present utility model: the pusher machinery that is connected with pusher frame 6 promotes paver 3 as bulldozer, loader and advances.In the process of advancing, elevation that the sensor of levelling instrument 9 will pave and road surface benchmark compare, and give control system with discrepancy in elevation signal feedback, send instruction by control system, 2 risings of control oil cylinder or decline, thus connection frame 4 drives the correspondingly adjustment up and down of paver 3 dos in driving.Because the design of T-slot 10 and T shape bar 15 can slide up and down these two parts relatively between middle frame 4 and the adjustment rack 5.So that the high and low position of connection frame 4 and even paver 3 in adjusting at any time by oil cylinder 2, the planeness on the road surface, back that guarantees to pave, and then raising integral construction quality.
Claims (4)
1, a kind of pushing-type stabilized soil paver rear end automatic regulating apparatus, it is characterized in that: the T shape bar (15) that is provided with T-slot (10) and is mated between middle frame (4) and the adjustment rack (5), on the connection frame (4), oil cylinder (2) lower end and adjustment rack (5) were fixing during oil cylinder (2) upper end was fixed on.
2, pushing-type stabilized soil paver as claimed in claim 1 rear end automatic regulating apparatus is characterized in that adjustment rack (5) is connected with pusher frame (6) by lateral pin (7).
