The specific embodiment
See also Fig. 2 to Fig. 5, a kind of movable shield structure scraper, the main backing plate 2 that comprises the tool rest 1 that is fixed on the cutter head panel 4 and cutter head 3 and fixing described cutter head 3, be provided with a backing plate chamber 12 in the described tool rest 1, described main backing plate 2 is fixed in the described backing plate chamber 12, cutter head 3 stretches out from 12 belows, described backing plate chamber, also comprises at least one adjustable plate 121 of being located at main backing plate 2 tops in the described backing plate chamber 12.
See also Fig. 3 and Fig. 3 a, tool rest 1 side is provided with a step 14, is used for making things convenient for the location of tool rest 1 and cutter head panel 4.Tool rest 1 can be fixedly connected with cutter head panel 4 by modes such as welding, riveted joints, and the firm performance that is connected with cutter head panel 4 in order to strengthen tool rest 1 can also respectively be established one with left surface and be strengthened gusset 41 above tool rest 1.
Be provided with a backing plate chamber 12 in the tool rest 1,12 left sides, backing plate chamber are provided with an opening, convenient main backing plate 2 and adjustable plate 121 and the resilient sleeper-bearing 122 installed.Adjustable plate 121 and resilient sleeper-bearing 122 are provided with a removal hole, when dismounting adjustable plate 121 and resilient sleeper-bearing 122, can will use a hook that adjustable plate 121 and resilient sleeper-bearing 122 are taken out from backing plate chamber 12.After cutter head 3 and main backing plate 2 and adjustable plate 121 installed, can also opening be blocked by a baffle plate 11, prevent that backing plate from skidding off, baffle plate 11 is fixed on the tool rest 1 by upper bolt 111 and lower bolt 112.In order to prevent cutter head 3 excess Temperature when working, in a side or the both sides of tool rest 1 spray-hole 13 is set, current can be ejected on the cutter head 3 from spray-hole 13.
See also Fig. 4 and Fig. 4 a, main backing plate 2 bottoms are provided with dovetail groove 21, and end face is provided with a removal hole, conveniently assemble and disassemble master backing plate 2.See also Fig. 5, cutter head 3 bottoms are provided with the cutting edge 31 that adopts high-abrasive material to make, high-abrasive material can be the materials such as carbide alloy, man-made polycrystalline diamond (such as the PDC composite sheet), artificial TSP (TSP), its top is provided with a flange 32 that cooperates with described dovetail groove 21, cutter head 3 can be connected on the main backing plate 2 by flange 32 and dovetail groove 21 like this, prevents that rotation from appearring in movable cutter head 3.
Adopt said structure, the extension elongation that the height of change resilient sleeper-bearing 122 just can be regulated cutter head 3, and the resilient sleeper-bearing 122 that arranges between cutter head 3 and tool rest 1 also effectively reduces shock loading and the vibrations that bring to tool rest 1 in cutter head 3 courses of work.Wherein, the material of resilient sleeper-bearing 122 can adopt the bridge rubber bearing material, neoprene bearing is a kind of neoprene bearing product that is together formed by multi-layer thin steel plate and multilayer rubber sulfuration adhesion, this neoprene bearing has enough vertical rigidities, have again good elasticity and larger shear strain ability, specifically can be referring to TB/T 1893-2006 railroad bridge laminated rubber bearing.
Below describe installation and the use procedure of movable shield structure scraper described in the utility model in detail:
After tool rest 1 is fixed by step 14 and cutter head panel 4, can fix by the mode of welding, and strengthen the switching performance of tool rest 1 and cutter head panel 4 by gusset.Cutter head 3 goed deep into backing plate chamber 12 downwards from the through hole at 12 tops, backing plate chamber after, main backing plate 2 is packed into from the opening of tool rest 1 side in the backing plate chamber 12, and the flange 32 at cutter head 3 tops is embedded in the dovetail grooves 21, finishes being connected of cutter head 3 and main backing plate 2.
The adjustable plate 121 of from the opening of tool rest 1, packing into, the extension elongation of regulating cutter head 3.In order to alleviate cutter head 3 vibrations to equipment when working, some resilient sleeper-bearings 122 can be set between adjustable plate 121 and main backing plate 2.At last, use baffle plate 11 that the opening of tool rest 1 side is blocked, and by upper bolt 111 and lower bolt 112 baffle plate 11 is fixed on the tool rest 1.Wherein play to have at least in the bolt 112 a lower bolt 112 to be positioned at cutter head 3 places places, after lower bolt 112 stretched out from the screwed hole of tool rest 1 side, the cutter head 3 of conflicting can slide in dovetail groove 21 to cutter head 3.
In case when needing to change cutter head 3, adopt said method to finish the replacing of cutter head 3, and according to actual needs the thickness of adjustable plate 121 is regulated, just can control the extension elongation of cutter head 3, utilize the rock in the corresponding scope of 3 pairs of new cutters of scraper to carry out scraping, need not to adopt and manually deepen breaking tank, save human cost and accelerated construction speed.
With respect to prior art, movable shield structure scraper described in the utility model is regulated cutter head 3 by adjustable plate 121 extension elongation, not only effectively avoid the excessive problem of new cutter load, and need not manually to deepen breaking tank, effectively improved efficiency of construction.Simultaneously, the vibrations the when resilient sleeper-bearing 122 that arranges between main backing plate 2 and adjustable plate 121 also effectively reduces equipment work have improved the stability of equipment work; At last also be provided with spray-hole 13 in the side of tool rest 1, the liquid with water or other coolings when cutter head 3 work is ejected on the cutter head 3 by spray-hole 13, has reduced the operating temperature of cutter head 3, has prolonged the working life of cutter head 3.
More than describe preferred embodiment of the present utility model in detail, the ordinary skill that should be appreciated that this area need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all in the art technician according to the utility model design on the prior art basis by logic analysis, reasoning or according to the available technical scheme of limited experiment, all should be among the determined protection domain by these claims.
