Background technology
At present, no matter be that city or rural area high buildings and large mansions are rised sheer from level ground as emerging rapidly in large numbersBamboo shoots after a spring rain, people are live and work in the building.But,, therefore require buildings to have certain sound insulation value upstairs because or the sound that sends of other room people's activities can have influence on downstairs or work, study or the rest in other rooms because there are some quality problems more or less in the sound insulation in building.The acoustical behavior of test architecture thing will have an acoustical generator, hits floor with it and sounds, and also has a noise tester, the utility model application be the ground beating device that causes noise.
For the ease of measurement data is compared, the ground beating device has all been made standard at home and abroad, as ISO140, EN20140, ASTME492, GBJ75 etc.Now the ground beating device all adopts the structure of 5 tups that multiple mode arranges, and each tup weighs 500 grams, and tup falls continuously and hits ground the sound takes place, and height of drop is 40mm, and ground is hit with the speed of per second 10 times in 5 tups knocking ground that falls in turn.Distance between 5 tups is 100mm, and the vertical range of 5 tup lines and each supporting leg is 100mm.
The ground beating device is a kind of unfixed testing apparatus, carry, require light, rational in infrastructure, easy to use, but that uses at present all is the structure of structure heaviness, the use steel are made, 25kg weighs, some device rotates when tup falls, and has adopted the labyrinth of two hammer stems, for the vertical range that reaches supporting leg and tup line is the requirement of 100mm, adopted supporting leg to pull out the bascule that takes in outward in base plate plane, the utility model improves for this reason.
Summary of the invention
The purpose of this utility model is for providing a kind of rational in infrastructure, carries lightly, and cost is low, easy-to-use ground beating device.
The technical scheme that realizes the foregoing invention purpose is as follows:
Has a general frame, main shaft is housed on framework, belt pulley is housed on main shaft, belt pulley is connected with motor by belt gear, even compartment of terrain vertical fixing has 5 eccentric wheels on the main shaft, the all corresponding peening hammer of each eccentric wheel, the angle that two adjacent eccentric major axis form in the space equates.Lift shaft is equipped with on top at each hammer stem, the distance of lift shaft and main shaft is less than the length of eccentric wheel major axis, the integrally-built the right and left of frame-type is a column, on, down for putting the beams in place and underbeam, last, right and left is equipped with two risers respectively between the underbeam, by bearing main shaft is housed between riser, 5 described eccentric wheels are housed respectively on main shaft, at upper beam 5 support sets are housed, underbeam is equipped with 5 orienting sleeves, and described hammer stem passes support set and orienting sleeve, on a left side, the bottom of right column is connected with base plate, base plate and framework form integral body and structure, and base plate is of a size of 〉=500 * 250mm, and three fixing supporting legs are housed on base plate.In the ground beating device outside fixing protective cover is housed, at the protective cover top handle is housed, protective cover is connected with base plate with framework by web member.Two sides at the corresponding orienting sleeve of hammer stem have guide surface, and this section is the guide section of hammer stem, are contained in the orienting sleeve of underbeam and are lined with orienting lug, have gathering sill on the orienting lug, guide section passes gathering sill, and guiding groove face and guide surface are coincide, and presents movable contact when hammer stem moves up and down.The material selection hard aluminium alloy of general frame structure also can adopt acetal plastic.Motor adopts manually or telepilot control.
Technique scheme can guarantee to reach the requirement of GBJ75, and has simple in structurely, and wearing quality is good, long service life, and noise is little between drive disk assembly, and is in light weight, is easy to carry, safe, beneficial effect easy to use.
