Description

Outstanding rail formula is used cutting machine more

The utility model relates to a kind of cement concrete shrinkage joint cutting that is used for, and the cutting machine that surface rubbing and anti-skidding line are made belongs to the concrete construction facility.This machine is applicable to the new-old concrete road face of intensity greater than 8MPa.

The construction of large tracts of land cement concrete, as highway, runway, square ground etc., need cutting to contract and stitch and expansion joint (E.J.),, then need make anti-skidding line by finisher surface rubbing or cutting machine because the local out-of-flatness of construction wrong or wear surface or the slip-resistant texture degree of depth are not enough.The cutting machine that adopts is made of four-wheel base, working plate, cutting power, saw blade, saw blade lifting and water system at present, saw blade and cutting power and transmission system thereof are installed on the working plate, connect with the four-wheel base by a moveable hinge, by the angle of screw mandrel adjusting working plate and base, the depth of cut of control saw blade.The walking of this machine promotes or sets up in addition power drive by manpower, and wherein two-wheeled initiatively, two-wheeled is driven.Direction of travel is advanced along the line of cut of drawing in advance by Artificial Control, and the straightness accuracy of cutting is not ideal enough.

Along with high-grade cement concrete pavement, airfield runway build increasing, requirement to workmanship and speed of application is more and more higher, use the difficult control of original cutting machine cut direction, the straight degree of seam or be used to polish and when cutting line overall depth be difficult to meet the demands; Saw blade is installed in machine front, needs tune to carry out secondary cut under the machine, and seam influences quality, inefficiency; Artificial guiding is adopted in cutting, and the human error factor is big, saw blade swing and walking speed irregular, make seam wide and seam is inconsistent deeply, saw blade damages to be accelerated.For improving workmanship and efficiency of construction, reduce cost, the outstanding rail formula of special development is used cutting machine more.

This machine is made up of several parts such as truss, cutting, traction, water supply, cutting part hangs on the adjustable guide rail that is located in the truss, rail length is greater than width of roadway, be placed on the truss that road wheel is housed by regulating bolt, the position, upper and lower, left and right of guide rail all can be regulated, and has guaranteed the straight degree and the degree of depth of cutting.Cutting power, saw blade axis, saw blade are installed on the working plate, link to each other with Working cart by a moveable hinge, and depth of cut is by regulating the wire rope control that connects platen and Working cart.When the cutting resistance was big, the saw blade depth of cut can reduce automatically, guaranteed that the cutting resistance is not more than cutting power.Working cart top is provided with four wheels of tape guide groove, and wheel is suspended on the adjustable guide rail on the truss, is driven by the actuating unit that is provided with on the truss and makes back and forth movement, and concrete is carried out two-way average rate cutting.Because the cutting part of this machine can be done the both forward and reverse directions motion, therefore need not tune and can do to come and go cutting, cutting is once finished does not have the cutting dead band, save time, laborsaving, economize saw blade.Cutting speed can be selected according to depth of cut and concrete strength.A saw blade or many saw blades can be installed on the saw blade axis, a saw blade be installed be used for cutting the seam that contracts, two saw blades are installed are used to cut expansion joint (E.J.), many saw blades are installed, the saw blade spacing is used to cut anti-skidding line when being 1～3cm, the saw blade spacing is used for surface rubbing when being 0～2mm, has realized a tractor serves several purposes.This machine is equipped with four groups can turn to road wheel, and direction of travel is adjustable, and when making transverse cuts, the road wheel direct of travel is vertical with truss, and when doing vertically cutting, the crop rotation of will walking turns to for 90 °, makes direct of travel parallel with truss.The location suspension rod is equipped with at the truss two ends, overlaps with the saw blade cutting position, only needs mobile truss to make suspension rod overlap and can locate with position to be cut during operation.This machine also is equipped with pressure water-supply system, and saw blade is cooled off and cut surface is washed.

The great advantage of this machine of use be the straight degree of joint-cutting well, truss length is greater than having a lot of social connections, joint-cutting is once finished, and does not cut the dead band, can two-wayly cut, need not reverse end for end, thus save time, laborsaving, operating efficiency improves greatly, because the straight degree of joint-cutting is guaranteed, workmanship also improves greatly.The working plate that diced system is installed adopts gravity suspention design, and machine is had overload protection function, has reduced the saw blade loss, has prolonged machine application life.

Accompanying drawing is a constructional drawing of the present utility model.(1) is water inlet; (2) be delivery port, be used for the saw blade cooling; (3) be booster water pump; (4) be delivery port, be used for the cut surface flushing; (5) be movable motor; (6) be speed changer; (7) be guide rail; (8) be the guiding sheave; (9) be wire rope, be used to affect Working cart along the guide rail bidirectional walking; (10) be lifting handle, be used to regulate the saw blade lifting, the Cutting Control degree of depth; (11) be shop bolt; (12) be positioning disk; (13) be truss; (14) for adjusting screw, be used to adjust the locus of guide rail; (15) be stand leg; (16) be tensioning screw; (17) be the wire rope bend wheel; (18) be backstay; (19) be road wheel direction alignment pin; (20) be road wheel; (21) be the working plate lifting wire rope; (22) be the saw blade safety guard; (23) be safety plug; (24) be saw blade; (25) be saw blade axis; (26) be water-cooling-sprayer; (27) be working plate; (28) be cutting motor; (29) be Working cart; (30) be electric wire and water pipe; (31) be sprocket wheel; (32) be wire rope pulley; (33) be wire rope and chain tension bolt.

Preferred example of the present utility model is, selecting length for use is truss and the guide rail of 10m, apart from both ends 2m place two stand legs that road wheel is arranged is installed respectively, and effective cutting length is 8.5m.Adapted 7.5kw cutting motor, depth of cut are 18cm; Be used to polish or during rag, it is 40cm that mill is carved width; Adapted 0.55kw movable motor, by reducer and speed change gear, making the Working cart speed of travel is 1.8m/min or 2.6m/min, selects for use according to concrete strength and depth of cut during construction, movable motor is controlled by two-direction switch, but two-way operation; Adapted 0.55kw booster water pump carries out saw blade cooling and cut surface flushing simultaneously in addition.
