Description

The cement pavement trowelling machine that paves

The utility model relates to a kind of Portland Cement Concrete Surface Course floating construction equipment that paves that is used for.This machine is applicable to the large area concrete construction.

The construction of cement concrete road surface making, particularly high-grade highway, runway etc., in order to reduce vehicle pitching, very high to the requirement of surface finish.The equipment that is used for the leveling of concrete surface has multiple.Zaozhuang, Shandong Engineering Machinery Plant produces a kind of three-roller type evener, and this machine mainly is made of three rollers, and a roller of front is eccentric to be installed, and is rotated backward by driven by motor, and the concrete material that will exceed template pushes forward.Two rollers of this machine back are promoted complete machine and seesaw, and concrete is carried out roll-in carry slurry by another driven by motor.The walking beam that it uses than before, its biggest advantage are to have taked self-propelled, greatly reduce labour intensity, but vibrating effect reduces.This machine two ends frame is on template, and therefore, because machine is from great, vibrating roller drives complete machine oscillation template strength and the requirement of supporting steadiness are improved; In addition, the eccentric vibrating roller of installing takes to push the stirring mode, when concrete flowability hour, walking resistance increases, and can produce the climbing phenomenon, can not guarantee surface evenness; In addition it, the walking roller rolls on template, the flatness of template interface, factors such as the sand grains that template surface may exist and self straightness accuracy make concrete surface produce big ripple and concave surface; Vibrating roller can only linear contact with concrete surface, and vibration efficiency is low, can't adapt to mobile less concrete construction, even the concrete of medium flowability, its operation also often needs repetition for several times.Above-mentioned situation does not adapt to the concrete road construction needs of high speed development far away.

In order to solve the deficiencies in the prior art, in concrete construction the leveling of collection stirring, vibratory compaction, slurry is carried in roll-in and the surface compaction troweling acts on one, the spy has developed novel concrete pavement spread trowelling machine.

This machine is made of vibration stirring roller, walking roll-in roller, self-service steering gear, the floating plate of vibration and corresponding driving device.Vibration stirring roller is positioned at the front portion of machine, adopts the method for setting-up eccentricity body to make centre-of gravity shift, and eccentric body is distributed on roller one side along the roller length direction, makes roller produce eccentric weight, produces vibration when motor drives rotation.The eccentric body installation that is in line, the concrete material that will exceed template turns over forward to be cut, and eccentric body and roll shaft cut oblique forward the turning over of the concrete material that exceeds template to becoming the inclination angle to install, and produce the screw distribution effect.Vibration stirring roller has vibration and stirring double action, and is consistent with limit mould planeness through the concrete height that vibration stirring roller is handled.The walking roller is two live-rollers pressure rollers in the same way, in the walking process concrete is carried out roll-in, carries slurry, the direct of travel advance and retreat are adjustable, design has self-service steering gear on the walking roller, when running into to turn in the road surface or because of piling up the unequal reason of material need turn to the time in the place ahead, only need the steering tiller on the manipulation operations platform to make the self-service steering gear of machine one end be positioned at the roller below, walking roller support machine one end weight is slided on the shaped steel of the peculiar angle of self-service steering gear and is halted, and the other end then continues to roll on template and machine is turned to.When machine went to required direction, steering tiller is multiple to neutral position, and steering gear was risen, and breaks away from template surface, machine two ends advanced in unison.Vibrate floating plate by hanging beam with pull beam and pull at the machine rear, floating plate has certain width, and vibrator is housed above.The back of floating plate when the lower edge slips at concrete surface, forms smooth surface along being provided with reinforcing beam under plate gravity and vibration force effect, the reinforcing beam straightness accuracy is proofreaied and correct by the adjustment bolt of design.Be suspended on respectively on the frame before and after the floating plate, all adjustable before and after the suspension height.Forward mounting is provided with elastic body, can adjust floating plate and the floating angle of concrete surface and the size of vibration force, after be suspended on when being used for mobile less concrete and can loosen fully, make floating plate be pressed in concrete surface, whole gravity and vibration force are all acted on the concrete surface.When being used for mobile bigger concrete, limit the floating plate height that sinks by adjusting bolt, make it to float on concrete surface, it is smooth to prevent to influence concrete under situations such as shutdown.When complete machine needs backward, to handle the lifting handle that is located on the console and rise floating plate, when putting down floating plate when advancing once more, the parameters of former adjustment remains unchanged.The weight of eccentric body and height can be changed on request to adapt to the concrete of different performance, can stir the preceding more accumulation material of machine and can not produce the climbing phenomenon.Vibration stirring roller is suspended on the frame by the elasticity connection, even adopt bigger vibration force, also can the stability of template not threatened.Thereby can use the upright side form of common templates and method for supporting and as track.

This machine adopts suspension type vibration stirring, under the situation that does not increase template support steadiness, can increase vibration force, improves concrete vibratory compaction effect; Adopt the adjustable eccentric body, make the stirring increased functionality of this machine, stopped the climbing phenomenon, the concrete integral smoothness improves; Adopt self-service steering gear, flexible and convenient operation; Suspension type is vibrated the design of floating plate, emphasizes in larger scope smooth, and concrete has the redistribution trend under the floating plate under the vibration effect, has eliminated the concrete surface ripple glaze that various unfavorable factors may cause; Facilitated Flocculated Cement body disperses, and airtight surface pore forms smooth bright and clean concrete surface layer.
