Abstract

The present invention relates to a vibration compacting machine used for rolling a slope surface, which is provided with a rolling roller and an engine arranged on a machine frame. The machine frame is provided with a plurality of function points of traction force. When the engine is not inclined, the included angle of connecting lines and horizontal lines from the function points to the axle centers of the rolling roller is equal to the slope angle of the slope. Thus, when the compacting machine is driven to upward roll, the engine can not be excessively inclined. The compacting machine is also provided with an enclosed-type controlling rope arranged on the function points of traction force and an adjusting device of the controlling rope. The controlling rope is in a triangular state under the tensile force of a traction rope. Thus, when the triangular is changed, the inclined rolling operation and horizontal movement can be realized.

Description

Vibratory compactor

The present invention relates to a kind of vibratory compactor, be used for all constructional materialss of compacting on horizontal plane or slope.

When comparatively smooth or in easy flights surperficial of compacting, adopt general vibratory compactor can reach requirement.But for the bigger inclined-plane of the gradient and since compacting machine on motor do not allow undue inclination, thereby must take measures to make motor can not keep basically or the angle of slope less than License Value.U.S. Pat 4260281 discloses a kind of vibratory compactor that is exclusively used in the compacting inclined-plane.This compacting machine comprises a frame, a rack-mounted tamping drum, a motor that drives the cylinder vibration by eccentric shaft.This motor is installed on the support of being located on the frame, and support rotation relatively.Therefore, outside pull rope is adjustable at the line in junction on the frame and tamping drum axle center with the angle between the motor short transverse.When work, earlier with engine rotation, make its angle of slope equal domatic slope angle by operating mechanism.Thereby when upwards rolling, though rack inclining does not tilt during the relative horizontal plane of motor.Though this compacting machine has solved the tilt problem of motor, it is complicated that its structure still seems, and this compacting machine lateral displacement on the slope also must be finished by means of lifting appliance.In addition, this compacting machine can not carry out domatic oblique rolling, and oblique to roll for compacting domatic corner wide at the top and narrow at the bottom be very necessary.

The objective of the invention is to provide a kind of simple in structure and vibratory compactor that can obliquely roll at above-mentioned weak point of the prior art.

The solution that realizes the object of the invention is: the motor that the vibratory compactor that is provided has that a frame, rack-mounted tamping drum, are installed on the frame and vibrates by the rapids drive tamping drum of flat eccentric shaft.On two curb girders on the frame, be provided with the application point of several tractive force, the slope angle that the tractive force application point equals to be rolled slope to the line and the horizontal angle in tamping drum axle center when motor does not tilt, this compacting machine also is provided with an enclosed shape control rope on the pulley that is enclosed within hinged and tractive force application point, a bit connecting of this control rope with drag rope, stressed back (to call stressed triangle in the following text) triangular in shape.Corresponding therewith, on frame, also have one can drive the adjusting device that the control rope moves along pulley.

During work, earlier the pulley of suit being controlled rope according to the slope angle of slope is installed in the junction of corresponding connecting arrangement.When being pulled upward slope, compacting machine is parallel to slope owing to the suffered traction line of action of force of frame, and pass through cylinder axis again, promptly this tractive force position and horizontal angle equal the slope angle of slope, so not run-off the straight of the relative horizontal plane of frame, be that motor on the frame can not tilt, guaranteed the operate as normal of motor.When compacting machine rolls after the slope pushes up, compacting machine laterally need be moved the width of a cylinder, so that carry out rolling next time.The control rope is moved a certain distance, even the apex offset certain distance of triangle control rope along pulley.Will be oblique descending when so compacting machine is descending along the direction that departs from former up route, arrive the slope at the end, the summit of triangle control rope is recentered, thereby finished the lateral displacement of compacting machine.Roll for the oblique of slope end, its reason is identical with the lateral attitude of above-mentioned compacting machine.

Below in conjunction with accompanying drawing content of the present invention is described in detail.

Most preferred embodiment of the present invention as Figure 1-3.Frame 1 is a rectangular frame.Eccentric shaft 2 and tamping drum 3 are sleeved on the frame 1, and Diesel engine 4 is installed in the rear portion of frame 1, and a centrifugal clutch 6 is arranged on its output shaft 5.Centrifugal clutch 6 engages with drive pulley 7 when the rotating speed of diesel engine 4 reaches certain value, drives eccentric shaft 2 by driving-belt 8 and driven pulley 9 and rotates, thereby make tamping drum 3 produce vibration.Respectively be welded with an otic placode 10 on two curb girders of frame 1, otic placode 10 is provided with the stress hole 11 that three (or more a plurality of) connect pull rope.The slope angle that stress hole 11 equals slope to the line and the horizontal angle α (to call the angle of traction in the following text) in cylinder 3 axle center when motor does not tilt.Because the center of gravity line of frame 1 is by the axis of cylinder 3, so when pull rope by stress hole 11 during along the direction parallel traction compacting machine with slope, the traction line of action of force also passes through the axis of cylinder 3, and equals above-mentioned alleged angle of traction α with horizontal angle.So frame 1 still keeps level, promptly diesel engine 4 does not tilt.For make frame 1 steady more, the center of gravity line of frame 1 can be adjusted in when work depart from slightly forward cylinder axis some.In order to adapt to the slope of different slope angles with fewer purpose stress hole 11, the difference of the angle of traction of adjacent stress hole can be designed to be slightly less than the permission inclination angle of diesel engine 4, like this when compacting machine is worked, as long as select corresponding stress hole as towing point according to the slope angle of slope.Can guarantee the operate as normal of diesel engine 4.Control rope 12 in the present embodiment and adjusting device 13 thereof are as shown in Figure 3.Control rope 12 seals, and it is enclosed within on the fixed pulley 14 that is articulated in the stress hole 11, and this fixed pulley 14 is hinged in the stress hole 11 by dismountable bearing pin 15.1: 16 of work time control rope making rope 12 connects with pull rope 17.Therefore after stressed, control rope 12 (to call stressed triangle in the following text) triangular in shape.The adjusting device 13 of control rope 12 is arranged on the leading section of frame 1, and the reel 20 that it comprises its axis that reducing gear 19 that a motor 18, one are driven by motor 18 and one drives by reducing gear 19 and both sides pulley 14 line quadratures reaches two stay cords 21,22 that the homonymy at reel 20 oppositely twining and forms.Stay cord 21,22 respectively with the stressed leg-of-mutton base of control rope 12(between pulley 14) be connected.Therefore when motor 18 rotates, can drive by reducing gear 19, reel 20, stay cord 21 or 22 and to control rope 12 and move, thereby can change the position of stressed triangular apex 16 along pulley 14.When compacting machine upwards rolled under normal conditions, being subjected to the force triangle was isosceles triangle.When needing lateral displacement after compacting machine arrives the top, slope, during as shown in Figure 5 traversing to the right, but starter motor 18 is offset stressed vertex of a triangle to the right, and promptly stressed leg-of-mutton right hypotenuse is less than left hypotenuse.So compacting machine will be oblique descending along the direction that is offset to the right with respect to original route.Arrive the slope, motor 18 counter-rotatings make stressed vertex of a triangle 16 get back to former center at the end, and the corresponding distance that also should move right of the winch on the top, slope this moment, have promptly finished the lateral displacement of compacting machine.

Oblique situation about rolling as shown in Figure 6.Its principle is identical with oblique descending lateral displacement.When compacting machine is oblique when rolling, stressed vertex of a triangle is offset to the right left; During oblique rolling, stressed vertex of a triangle is offset left to the right.

The adjusting device 13 of above-mentioned control rope 12 also can adopt structure as shown in Figure 4: the reducing gear 19 that it comprises motor 18, driven by motor 18, its axis leading screw 23 and the nut 24 that with leading screw 23 mesh parallel with both sides pulley 14 lines that is driven by reducing gear 19, nut 24 is connected with control rope 12 between pulley 14.

The adjusting device of control rope also can adopt hydraulic transmission mode: with the piston rod of oscillating oil cylinder and control rope hinged (pin joint can on stressed leg-of-mutton arbitrary limit), cylinder body be hinged on the frame.Can drive the control rope when cylinder action moves along pulley.

Usually rolling comparatively smoothly when surperficial, compacting machine is directly dragged by tractor.Connect conveniently in order to make, the front end of this compacting machine is also hinged, and one turning 180 horizontally tracting head 25(sees Fig. 1).When rolling the inclined-plane, horizontally tracting head 25 is positioned at the frame top; When rolling flat surfaces, this horizontally tracting head 25 connects with tractor after 180 ° of bearing pin 26 upsets.

The adjusting device of diesel engine in this compacting machine and control rope can adopt the general line traffic control that has, but preferably adopts wireless remotecontrol.Fig. 7 has provided the schematic diagram of beeper.This remote control comprises the executing agency 29 of a radio transmitter 27, receiver 28, control diesel engine and the executing agency 30 of control and regulation device.Control procedure to diesel engine is: send a signal from emitter 27, start executing agency's 29 actions after receiver 28 received signals, drive throttle lever 32 actions of diesel engine by connecting rod 31, thereby can change the rotating speed of diesel engine 4, centrifugal clutch on the diesel engine output shaft is thrown off or joint, the vibration when tamping drum of realization compacting machine is up, non-vibrating purpose when descending.The control procedure of adjusting device to the control rope is: start executing agency's 30 actions after receiver 28 received signals, make motor 13 forward or reverse, thereby realize moving of control rope.
