Abstract

The utility model relates to a concrete paver capable of leveling and turning, which comprises two walking leveling rollers fixed below two side bedplates, and an eccentric vibrating roller, wherein motors, a speed reducer chain wheel shafts, belts, chains, etc. are arranged on the side bedplates; a leveling roller with left and right helical blades is arranged in front of the eccentric vibrating roller. Supporting wheels are respectively arranged between the two walking leveling rollers and at the front ends of the bedplate on the same side, so that the leveling and turning functions can be achieved. The utility model avoids the sand leakage and the shrinking pit of the existing equipment, has sensitive turning and easy operation, saves manpower and material resource, and guarantees the construction quality.

Description

A kind of concrete spreader that can flatten and turn to

The concrete spreader that can flatten and turn to of rigid pavements, plane such as the utility model relates to and a kind ofly is used to build highway, square, airport.

The present concrete spreader that uses, exist following weak point: 1. because of concrete material when stacking with manually flattening, often do not reach standard, be uneven, when paver advances work, because eccentric vibrating roller counter-rotating, push away jolt ramming before the concrete that will exceed, make the slurry flows that squeezes out add flatly to lacking concrete recess, thereby high source does not have the only remaining sandstone of mud, solidify the back and produce leakage sand crackle, recess produces the hole crackle that contracts because of no sandstone solidifies the back; 2. pile up because of cement concrete and be uneven, and the resistance difference, so usually make paver change direction when using, and adjustment is one by mentioning a middle roller of three rollers, the friction of this that minimizing is mentioned, change direction, and can change direction during null in the practical application, and the place ahead concrete resistance not radical change simultaneously not direction.

The purpose of this utility model be to overcome the deficiencies in the prior art part and provide a kind of can leveling and the concrete spreader that turns to, avoided leakage sand and the hole phenomenon that contracts, turn to sensitivity, operation light, saved expense, improved work efficiency.

The purpose of this utility model is achieved in that the utility model is to be provided with between the flattening roller of band left and right sides helical blade and two traveling pressure rollers in eccentric vibrating roller the place ahead of original paver and homonymy platen front end respectively is provided with a support wheel, just can reach leveling and the function that turns to, and keep original function.

Adopt above-mentioned design scheme, increase paver cost of production that can be not too much is made easily, and is easy for installation, turns to during operation flexibly, saved manpower and materials, guaranteed construction quality.

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

Fig. 1 is the utility model structural representation.

Fig. 2 is a flattening roller interlock schematic diagram of the present utility model.

Fig. 3 is two a support wheels interlock schematic diagram of the present utility model.

As Figure 1-3, a kind of concrete spreader that can flatten and turn to, it comprises by being fixed on both sides platen (4,5) low two traveling pressure rollers (1 that have bearing support and sprocket wheel, 2) and an eccentric vibrating roller (3), one side stage plate (4) is provided with motor (6), reductor (8), sprocket shaft (10) and cover are furnished with interlock traveling pressure roller (1,2) belt (7) and chain (9,11), opposite side platen (5) is provided with motor (12), sprocket shaft (14) and cover are furnished with the belt (13) and chain formations such as (15) of the eccentric vibrating roller of interlock (3), it is characterized in that: the place ahead of eccentric vibrating roller (3) is provided with the flattening roller (16) of band left and right sides helical blade, two traveling pressure rollers (1,2) be provided with between by axle sleeve (20) and the fixing back support wheel (21) of axle (22), the front end of homonymy platen (4) is provided with by axle sleeve (23) and the fixing preceding support wheel (25) of axle (24), front and back support wheel (25,21) pass through three connecting rods (27 by foot pedal lever (26), 28,29) connect, connecting rod (28) is connected by axle (30) with platen (4) upper bracket (31).Operating process is as follows: after connecting power supply, motor (6) on the platen (4) rotates, by by belt (7), reductor (8), chain (9), sprocket shaft (10), chain (11) drives slicking-in roller (1) walking and flattens the road surface, sprocket wheel and chain by roller (1) other end drive another slicking-in roller (2) walking pressing road surface, eccentric vibrating roller (3) passes through belt (13) by the motor (12) on the platen (5), wheel shaft (14) and chain (15) carry out transmission and impact the jolt ramming road surface, the flattening roller of paver front (16) is by an end sprocket wheel (17) of eccentric vibrating roller (3), chain (18), sprocket wheel (19) drives, the cement concrete redundance pushes away before along with the rotation of flattening roller (16) blade, horizontal pushing away, pocket is added flat through eccentric vibrating roller (3) it is impacted jolt ramming again, thereby avoided leakage sand, phenomenons such as hole contract.Before and after support wheels (25,21) be 75 ° of oblique angles with template at ordinary times and prop up and drop on the template, when turning to, depress foot pedal lever (26), make two support wheels (25,21) perpendicular to template, with fragmented template of four rollers (1,2,3,16), as advancing to left, start and advance, because of this head of four rollers (1,2,3,16) all de-orbits, this side does not have power, can only be in the original place, opposite side advances with roll shaft, and paver has just changed direction, starts the back row during right-hand rotation, machine direction to be paved continues to move ahead after changing again.
