The utility model has the advantages of small size and light weight, and is flexible and nimble, and is suitable for slotting of various bending and irregular fissures of asphalt pavement; at the same time, the utility model adopts vacuum sucking and cleaning to thoroughly clean the fissures.

Description

The hand held asphalt road facing cut seam machine of band seam cleaning function

Affiliated technical field

The utility model belongs to the asphalt pavement conserving equipment technical field, relate to a kind of be used for band seam cleaning function that the damaged fluting of asphalt pavement crack is handled mill the seam machine.

Background technology

Along with the develop rapidly of highway construction cause, flexible pavement mileage open to traffic number is more and more, needs the flexible pavement of maintenance also constantly to increase simultaneously.The crack is the most common, the most incident a kind of damaged form of flexible pavement, the crack appears if the untimely envelope of being filled out is repaired, then rainwater and other foreign material will enter the following surface layer or the basic unit on road surface along the crack, make it softening, cause pavement structural strength to reduce, quicken the damage on road surface, just because of this in time slots to the crack breakage of flexible pavement and to fill out envelope and repair and just seem particularly important.And the damaged great majority in the crack of flexible pavement are crooked, not straight, irregular, not only there are deficiencies such as cost height, heaviness, mobility difference in traditional repair apparatus or fluting apparatus, and can't satisfy the fluting processing requirements of the damaged form in different cracks in actual applications, inefficiency, result of use are poor, the mode that seam is blown in furthermore many again employings is cleared up the crack, and raked joint is not thorough.

The utility model content

The purpose of this utility model is to overcome the weak point that prior art exists, and then a kind of novel and reasonable structure, operation light and flexible is provided, can fully satisfies the fluting processing requirements of the damaged forms in different cracks and clears up the hand held asphalt road facing cut seam machine of the band seam cleaning function in crack easily and thoroughly.

Technical solution of the present utility model is achieved in that the hand held asphalt road facing cut seam facility of the band seam cleaning function that is provided have the sole of a band caster wheel and adjustable height support wheel, be provided with a vertical milling cutter in sole front end bottom, this vertical mill principal axis is driven by the prime mover (class such as petrol engine, Diesel engine or AC-DC motor) that is attached on the sole by gear-box and milling cutter driving belt; Be provided with a debris collection tube in the dead astern of vertical milling cutter, the rear port of this debris collection tube feeds a debris collection right side that is attached to the band stack on the sole, stack stretches out from the lower left of debris collection and enters an air-introduced machine that is attached on the sole, is driven the wheel rotation of air-introduced machine by the blower fan driving belt by prime mover.

Compared with prior art, the utlity model has following beneficial effect:

1, the crack breakage of adopting vertical milling cutter that flexible pavement is occurred processings of slotting can adapt to the not too crack of rule of the various trends of flexible pavement, and is easy to drive in crack central authorities when slotting, and is difficult for wandering off, and also can reduce simultaneously the destruction of ground surface material on every side.

2, utilize air-introduced machine to adopt vacuum to inhale the mode of sweeping, the ground surface material chip suction that milling is got off is swept and collected, more thorough to slot cleaning.

3, the fluting processing and the raked joint processing of asphalt pavement crack breakage are carried out simultaneously, improved operating efficiency greatly.

4, adjustable height support wheel and caster wheel are installed under the sole, have improved the maneuverability that mills the seam machine, the very suitable various irregular flutings that move towards the crack are handled.

The specific embodiment

Referring to Fig. 1, Fig. 2 and Fig. 3, the utility model mainly is made of vertical milling cutter 1, debris collection tube 2, adjustable height support wheel 3, sole 5, caster wheel 6, debris collection 9, blower fan driving belt 13, petrol engine 14, gear-box 20, air-introduced machine 21 and stack 22 etc.Gear-box 20 is contained in sole 5 front ends, vertical bevel gear 19 that being provided with in it is meshing with each other connects and horizontal bevel gear 18.Vertical milling cutter 1 is contained in the axle head of vertical bevel gear 19, and vertical bevel gear 19 meshes with horizontal bevel gear 18, and is driven by milling cutter driving belt 16 by petrol engine 14.The front port of debris collection tube 2 is in vertical milling cutter 1 dead astern, the rear port of debris collection tube 2 feeds debris collection 9 right sides, stack 22 stretches out from the lower left of debris collection 9 and enters air-introduced machine 21, is driven the wheel rotation of air-introduced machine 21 by blower fan driving belt 13 by petrol engine 14.In the practical structures, the shape of debris collection tube 2 and debris collection 9 can be rectangular cylindricality, also can be cylindrical.Adjustable height support wheel 3 and caster wheel 6 are installed in sole 5.

This course of work of milling the seam machine is as follows:

During construction, will mill the termination that the seam machine is pushed into the Damages of Asphalt Road Surface crack, and mill seam machine direction of advance and should keep consistent with fracture strike; Vertical milling cutter 1 is aimed at crack central authorities, start petrol engine 14, vertical milling cutter 1 is started working by horizontal bevel gear 18 in milling cutter driving belt 16 and the gear-box 20 and vertical bevel gear 19; Make air-introduced machine 21 entrys into service by blower fan driving belt 13 simultaneously; Counterclockwise slow rotation hand wheel 12 slowly lifts adjustable height support wheel 3 by screw rod 8, screw bolt seat 7 and fork 4, and vertical milling cutter 1 slowly is milled in the crack, and until the groove depth that requires, handwheel 12 stops the rotation; Then, hold handrail 11 and promote to mill the seam machine and slowly move forward, the processing of slotting of 1 pair of crack of vertical milling cutter along fracture strike.With the above process while, because the running of air-introduced machine 21, by stack 22, debris collection 9 and debris collection tube 2,, the ground surface material chip suction that vertical milling cutter 1 milling is got off is swept and collected in the debris collection 9 in the very strong pull of vacuum of front port formation of debris collection tube 2.Article one, after the crack fluting was handled, slowly rotation hand wheel 12 was slowly propped up sole 5 support wheel 3 downwards clockwise, and vertical milling cutter 1 is slowly withdrawed from from the crack, and until being above the ground level, handwheel 12 stops the rotation.If after also need can be pushed into its termination with milling the seam machine near processings of slotting of another crack, proceed to slot and raked joint work.Label 10 is the screw rod supporting seat in the accompanying drawing; 15 are the band transmission shield; 17 is bearing support.

The damaged form of asphalt pavement crack as shown in Figure 4, its fluting size is a foundation with the crack width and the order of severity usually, the loose wall surface material that groove width should reach at least with the crack breakage mills away, till exposing solid part, and then determine an appropriate fluting breadth depth ratio (groove width/groove depth), the most normal value of getting has 1: 1 (square groove as shown in Figure 5) and 4: 1 (shallow slot as shown in Figure 6).So, according to vertical milling cutter 1 milling depth different of different notching construction pattern selection different-diameters with control.
