Specific embodiment
Below in conjunction with specific embodiment, the present invention will be described in further detail.
A kind of concrete-bridge expansion joint facade grinding head, structure is as depicted in figs. 1 and 2, including upper support plate 3, under
Support plate 7, support shaft 2,1, two sanding block fixing axle 6 of coupling spindle and several sanding blocks 4, wherein sanding block 4 is used for bridge
Beam expansion joint facade is polished, can during the grinding process adjust automatically polishing position and polishing dynamics.
Upper support plate 3 and lower support plate 7 are arranged in parallel, and are fixedly connected by support shaft 2, and coupling spindle 1 is vertically set on
The upper surface center of upper support plate 3 drives coupling spindle rotation to be further driven to upper support for connecting sander by sander
Disk 3 and lower support plate 7 and sanding block rotation thereon carry out polishing operation.In the present embodiment, upper support plate 3 and lower support plate 7
It is disc-shaped structure, the diameter of disc support plate is 70mm, with a thickness of 12mm；Support shaft 2 is perpendicular to upper support plate 3 under
Support plate 7 is arranged, and is fixedly connected with the center of upper support plate 3 and lower support plate 7, and the diameter of support shaft is 18mm, and length is
100mm。
Even respectively in upper support plate 3 and lower support plate 7 to be furnished at least one set of symmetrically arranged through-hole, upper support plate 3 is led to
The through-hole of hole and lower support plate 7 is accordingly arranged up and down, for installing sanding block fixing axle 6.Upper support plate 3 is under in the present embodiment
It is respectively arranged with two groups of through-holes in support plate 7, is convenient for changing the position of position sanding block fixing axle 6, prevents concentrated wear serious
It reduces the service life.
Sanding block fixing axle 6, which is worn, to be connect in the through-hole in upper support plate 3 and lower support plate 7, and is fixed by nut, nut
Positioned at the top of upper support plate 3 and the lower section of lower support plate 7, as shown in Figure 2.In the present embodiment, the length of sanding block fixing axle
For 150mm, diameter 8.0mm.To prevent the nut of lower 7 lower section of support plate from slipping during the grinding process due to vibration,
The present invention is provided with via hole under stretching in the sanding block fixing axle 6 of 7 bottom face of support plate, via hole is perpendicular to sanding block fixing axle
Axis setting, be installed with positioning card 8 in via hole, limited for the nut to 6 bottom of sanding block fixing axle.
Sanding block 4 is arranged in the sanding block fixing axle 6 between support plate 3 and lower support plate 7, neighbouring
It is positioned between sanding block 4 by the limit sleeve 5 being sleeved in sanding block fixing axle 6, as depicted in figs. 1 and 2.
Sanding block 4 is triangle block structure, and as shown in figures 1 and 3, the length ratio of three sides of sanding block is 7：8:
10, the setting of such ratio, enable to sanding block be directed to during polishing operation boss different on facade into
The adjustment of row polishing position and dynamics of polishing provides guarantee to improve the grinding effect of facade.In the present embodiment, sanding block three
The length of side is respectively 35mm, 40mm, 50mm, sanding block with a thickness of 7mm.
The second side 43 of sanding block 4 and the connection end of third side 44 offer connecting hole 45, sanding block fixing axle 6
It is passed through from the connecting hole；In the present embodiment, the aperture of connecting hole is 8.2mm.42 facade of first side of sanding block 4 is polishing
Face, the present invention is to improve the service life of grinding efficiency, grinding effect and grinding head, in beating for 4 first side 42 of sanding block
The cutter head of high hardness alloy material is provided on flour milling.
Limit sleeve 5 is set in the sanding block fixing axle 6 between neighbouring sanding block 4, plays position-limiting action to sanding block.
In the present embodiment, limit sleeve is empty cartridge type column structure, and the outer diameter of limit sleeve is 16mm, internal diameter 8.2mm, and length is
31.5mm。
Certainly, in the present invention, the size of each component can be configured according to specific job position.
Assembling process of the invention is：Firstly, sanding block fixing axle to be passed through to a through-hole of upper support plate, according to polishing
Sanding block and limit sleeve, are successively set in sanding block fixing axle, when beating by the setting sequence of block, limit sleeve, sanding block ...
When abrading block and limit sleeve are covered between support plate and lower support plate, sanding block fixing axle is passed through into lower support plate and is consolidated with nut
Determine, then positioning card is inserted into the via hole of sanding block fixing axle, nut is limited；Another sanding block fixing axle and polishing
The installation method of block and limit sleeve is same as above, and two sanding block fixing axles are symmetrical arranged；Secondly, by the output of coupling spindle and sander
Axis is fixedly connected by axle sleeve, can carry out polishing operation.
For the present invention in operation process, the rotation of sander output shaft drives grinding head rotation, due to the effect of centrifugal force, makes
Sanding block 4 beats the concrete surface in expansion joint facade and polishes concrete.Since sanding block is to be actively socketed on polishing
In block fixing axle, 180 ° can be rotated freely, therefore when concrete surface is concave-convex or part is hard, sanding block can lead to
It crosses rotation to be finely adjusted, freely adjust and the job position of expansion joint facade and operation dynamics, raising grinding effect.
