Abstract

The utility model relates to a smearing component element, which is used for main working components of a concrete surface layer compression smearing machine. The element comprises four smoothing blades which are respectively in screw-shaped arrangement, each smoothing blade is connected with an angle modulation support bracket by a stiffener, the outer side of each regulating supporter is movably connected with a position socket by pin shafts, and the inner sides of the four regulating supporters are respectively hinged with four horizontal bars of a lifting support. With switching the lifting support by a shifting piece, the up-warping side of the blade can be lifted or fallen in order to adjust the slope angle of the blade. The outer side of each smoothing blade is slantways smeared with the rotating direction, which can cause the superfluous pulp-water on the concrete face to slide into the blank space of the base at the inner side following the diagonal blade, and the superfluous pulp-water can be filled in the holes in low land.

Description

The troweling assembly

Technical field

The utility model relates to a kind of troweling assembly, and it is the main working parts of the finisher used of concrete pavement compacting troweling, belongs to building machinery.

Background technology

In concrete or cement pavement, the ground construction, need to adopt finisher that the concrete pavement before solidifying is carried out the operation of compacting troweling.The troweling assembly is the main working parts of finisher, it is to be the cross arrangement by four troweling blades to be fixed on the chassis, be connected with the power transmission shaft of finisher by the chassis, when power transmission shaft rotates under power drive, four troweling blades promptly are driven to rotate, and concrete surface is carried out the troweling operation.But when four troweling blades of cross arrangement rotate with the axis, being vertically parallel forward smearing with direction of rotation draws together, this mode of drawing together of smearing can only be smeared the pulp-water in the blade rotary area to draw together and shakeout, run into the pin hole time then need to smear repeatedly draw together pin could be cheated floating, inefficiency, difficult quality Liu's height, the angle of inclination on troweling blade and ground is fixing in addition can not regulate, and functional performance is not good enough.

Summary of the invention

The purpose of this utility model provides a kind of troweling assembly that is used for concrete pavement compacting finisher, and it can solve the blade cross and arrange the defective of smearing the mode of drawing together that exists, to improve troweling operating efficiency and the quality to concrete pavement.

This troweling assembly contains positioning base and four troweling blades, and each blade is fixed with stiffener, and the central axle sleeve of positioning base links to each other with the finisher power transmission shaft, and axle sleeve is equipped with bearing assembly, and four troweling blades are arranged successively twist.Each troweling blade connects an angular adjustment support by stiffener, each outside of regulating support flexibly connects with connecting pin and positioning base, four horizon bars of the inboard of the adjusting support of four blades and a crane are hinged respectively, and the central axis of this crane links to each other with positioning base is coaxial.Said bearing assembly bearing packet overcoat, bearing and bearing inner sleeve, the central axis of said crane is connected with the waist-shaped hole of the central axle sleeve of positioning base by a horizontal stub shafts, fixedly connected with said bearing inner sleeve in these horizontal stub shafts two ends, bearing outside connects a shift fork, by shift fork shifting shaft bearing up and down, horizontal stub shafts is slided up and down in waist-shaped hole, and minor axis drives the inboard generation lifting displacement that crane makes the angular adjustment support simultaneously, thereby regulates the inclination angle of troweling blade.

In sum, four blades of this troweling assembly are arranged twist, and when ground was smeared in the rotation of this assembly, the outside of each troweling blade (side that promptly lands) was oblique smearing with direction of rotation and draws together.Thisly smear the mode of drawing together and manual to smear the action of drawing together similar, can make the unnecessary pulp-water of concrete pavement slide to along with blade is oblique in the blank space of wing base, pulp-water is pushed by blade and moves with base; When as concrete surface low hole, part being arranged, the unnecessary pulp-water that moves so far can be inserted in the hole.As seen, this design makes unnecessary pulp-water concentrated and mobile, so the concrete surface behind the troweling is more smooth bright and clean.In addition, the angle of inclination of troweling blade can be regulated as required, and is easy to use.

Description of drawings

Fig. 1 is the plan structure figure of this troweling assembly.

Fig. 2 represents the angular adjustment support of four blades and the annexation of crane.

Fig. 3 is that the A of Fig. 1 is to view.

Fig. 4 is the B-B sectional view of Fig. 3.

Among the figure, the 1-power transmission shaft; The 2-positioning base, 2-1-positioning base axle sleeve, 2-11-waist-shaped hole; The 3-shift fork, the fixed support of 3-1-shift fork; The 4-bearing assembly, 4-1-bearing outside, 4-2-bearing; The 4-3-bearing inner sleeve, the fulcrum that is connected of 4-4-bearing outside and shift fork; 5-angular adjustment frame; The 6-stiffener; 7-troweling blade; The 8-connecting pin; The 9-crane; The horizon bar of 9-1-crane; The 10-horizontal stub shafts, 11-ends a screw; The 12-key.

Shown in Figure 1, four troweling blades 7 of this troweling assembly are with helical pattern (likeness in form screw), and each blade is fixed with stiffener 6, stiffener 6 is the inclined-plane with the contact surface of blade, each blade 7 is tilted, and promptly the side (inboard) in face of direction of rotation M upwarps, and opposite side (outside) lands.Angular adjustment support 5 is fixed on the stiffener 6, and its outside (be blade 7 land side) flexibly connects by connecting pin 8 and positioning base 2.

The annexation of Fig. 2 (promptly remove the positioning base 2 of Fig. 1 after figure) expression troweling blade 7 and crane.

Visible crane 9 is provided with four horizon bar 9-1 among the figure, and the inboard of four angular adjustment supports 5 flexibly connects with each horizon bar 9-1 respectively.Therefore, when crane 9 upwards promoted, each was regulated the inboard of support 5 and is upwards drawn, and made the inboard of blade 7 upwarp the angle increase, otherwise reduced.

The A of Fig. 3 presentation graphs 1 is to view, and Fig. 5 is that the B-B of Fig. 3 analyses and observe.In conjunction with Fig. 3 and Fig. 4 as seen, the central axle sleeve 2-1 of positioning base 2 links to each other with 1 socket of finisher power transmission shaft, and both are with key 12 and to end a screw 11 fixing.Axle sleeve 2-1 is equipped with bearing 4-2, and bearing is provided with bearing inner sleeve 4-3 and overcoat 4-1; The central axis cross-under of crane 9 has horizontal stub shafts 10, fixedly connected with bearing inner sleeve 4-3 in the two ends of horizontal stub shafts 10, bearing outside 4-1 is connected with shift fork 3 by two fulcrum 4-4, shift fork 3 is provided with fixed support 3-1, when rotating shift fork when fulcrum rotates, bearing assembly 4 drives crane 9 by horizontal pin 10 and slides up and down in deciding the waist-shaped hole 2-11 scope of 2-1.Regulate the purpose that blade 7 upwarps angle thereby reach.

After finisher starts, rotating shaft 1 rotation, the positioning base 2 that links to each other with rotating shaft 1 drives crane 9 rotations simultaneously, and four troweling blades 7 are simultaneously by position base 2 and crane 9 driven rotary, and blade 7 i.e. work with smearing.Rotating also the moving on the concrete work face with finisher simultaneously of this troweling assembly advanced, and finishes the compacting troweling to whole concrete work surface layer.The angle of inclination of blade 7 can be regulated according to the needs of compacting or troweling operation.
