Abstract

The utility model relates to a concrete road surface grader for a highway, which is provided with a supporting frame and two foot frames for side wheels, a screed is arranged between the two foot frames for side wheels, and simultaneously, a drive mechanism which can make the screed move from left to right is arranged on the supporting frame. The utility model has simple structure and has the advantages of realizing mechanization control and continuous work, reducing construction strength of workers and raising work efficiency.

Description

Concrete road surface grader

The utility model relates to a kind of concrete smoother that is used for highway structure.

Be used at present the highway structure cement concrete pavement smooth be mainly disc type concrete road surface finisher, it is floating in the part, rigid pavement that this machine utilizes a circle to smear dish, work efficiency is low, it is powerful to work, and pavement quality does not reach the technical requirements of national standard " cement concrete pavement engineering construction and standards of acceptance ".

The purpose of this utility model is to overcome the defective of above-mentioned technology, and a kind of concrete smoother that can alleviate constructor's labour intensity, increase work efficiency, realize the mechanization of concrete pavement construction and work continuously is provided.

The utility model is provided with support and both sides wheel foot rest, and between the wheel foot rest of both sides screed is set, and is provided with the driving mechanism that makes the screed side-to-side movement simultaneously on support.

Further specify the utility model below in conjunction with embodiment and accompanying drawing.

Fig. 1: the topology view of present embodiment;

The A of Fig. 2: Fig. 1 is to view;

The B-B enlarged drawing of Fig. 3: Fig. 1;

The C-C amplification profile of Fig. 4: Fig. 1;

The D-D amplification profile of Fig. 5: Fig. 1;

Present embodiment is provided with support (4) and foot rest (1), (9) are taken turns in both sides, and between wheel foot rest (1), (9) screed (2) is set, and is provided with the driving mechanism that makes screed (2) side-to-side movement simultaneously on support (4).Driving mechanism in this example is provided in a side of motor (10), reducer (6) and gear (3), the connecting rod (5) on the support (4), the bearing (8) on the eccentric shaft (7) on (5) assembling gears of connecting rod (3), the other end assembling screed (2).Behind the starter motor (10), connecting rod (5) promptly drives about screed (2) and moves back and forth.

For ease of regulating the operating position of screed (2), be provided with the lifting regulating mechanism of screed (2) in this example, this governor motion comprises the elevating bracket (11) that is located on the support (4), sleeve (12), lifting shaft (13), handwheel (14), rotating shaft (15) and screw mandrel (16), handwheel (14) and rotating shaft (15) are bearing on the interior bearing of sleeve (12), screw mandrel (16) is fixedly connected also and lifting shaft (13) thread connection with rotating shaft (15), lifting shaft (13) lower end is by the main track (17) of paying, (18) connection screed (2), therefore rotate handwheel (14), relative motion by screw mandrel (16) and lifting shaft (13), can regulate the upper-lower position of screed (2), both sides all are provided with elevating mechanism in this example, simultaneously owing to be provided with the main track (17) of paying, (18), so elevating mechanism does not influence the side-to-side movement of screed (2).

Present embodiment also is provided with wheel foot rest drive unit, this device is provided with power transmission shaft (19), by being fixed on worm gear (20), coaxial worm (21) and the gear (22) and gear (3) engagement on the power transmission shaft (19), power transmission shaft (19) two is respectively by head sprocket (24) assembling in clutch (23) and wheel foot rest (1), (9), also be provided with in wheel foot rest (1), (9) with take turns (25) coaxial from sprocket wheel (26).Controlled clutch (23), the rotating by motor (10) can make complete machine advance or retreat, and in the accompanying drawing, template (27) is the auxiliary tools in the highway structure.

The utility model is simple in structure, and operation has realized mechanization and worked continuously, and has reduced workman's construction intensity, has improved work efficiency.
