Background technology
Hardness test hammer is applied to the hardness test work of road surface, ice face, mine rock more.Hardness test that prior art uses hammer, without equidistant slots on weight, the height that weight promotes at every turn is identical, but with the whereabouts of transmission shaft, the acting force of each generation has certain change, and the error of measurement can be larger.Adopt motor as drive unit, volume is comparatively large, controls inconvenient.In addition, rational snubber assembly is not set in a device.After transmission shaft puts in place, weight and equipment itself collide, grievous injury device.Hardness test hammer of the prior art does not arrange ventilation device, and when weight runs up and down, pressurized air forces air accumulation thus to produce larger resistance, is unfavorable for the operation of equipment.
Utility model content
It is accurate that the purpose of this utility model is to provide a kind of hardness measurement, can reduce equipment damage, hardness test hammer easy to use.
Hardness test hammer described in the utility model, comprise supervisor's soldering member, supervisor's soldering member is provided with chain cover soldering member, described supervisor's soldering member top is provided with upper cover plate, bottom is provided with tup, inside is provided with weight and transmission shaft, described weight has multiple equidistant slots, described chain cover soldering member inside is provided with drive sprocket, drive sprocket is connected with driven sprocket by simplex roller chain, be provided with gib block between drive sprocket and driven sprocket, simplex roller chain is provided with lift block, and described transmission shaft is provided with scale mark.
During use, this hardness test hammer is vertically placed, drive sprocket drives driven sprocket to rotate by simplex roller chain, lift block is positioned on simplex roller chain, drive sprocket rotates clockwise drive simplex roller chain, lift block is moved up, lift block hangs in the equidistant slots on weight, weight is upwards promoted, lift block arrives highest position, simplex roller chain is rotated further clockwise, lift block is separated with weight, weight in-position, then freely falling body, transmission shaft moves down due to the impact position being subject to weight, now, if weight returns original position, weight and transmission shaft relative distance change, dynamics of impacting when just causing weight again to work changes, test result produces deviation.But, when weight knocks the moment of transmission shaft, lift block can stick in the equidistant slots of weight, the position of weight is different, lift block sticks in different equidistant slots, because the range ability of lift block itself is constant, all can contact with weight after the identical time at every turn, thus eliminating the need the range difference between weight and transmission shaft, the impulsive force making weight at every turn fall to producing is all identical, with scale mark on transmission shaft, according to the distance that the certain number of times transmission shaft of impact falls, or the hardness of number of times impact place to judge that transmission shaft falls distance certain and impacts.
Described chain cover soldering member is provided with priority flow control valves, and priority flow control valves is by sebific duct connecting fluid pressure motor, and it is convenient that oil motor provides driving force to control.
Described tup inside is provided with flange in the bottom, and rubber blanket is sticky on flange in the bottom, and position is fixing firm, when transmission shaft falls to putting in place, when both touching the bottom, plays buffer action, prevents weight from directly clashing into mutually with supervisor's soldering member and damaging device.
Described rubber blanket is provided with mesopore, and the diameter of mesopore is greater than the diameter of transmission shaft, ensures that transmission shaft is close to supervisor's soldering member in rubber blanket outer, prevents rubber blanket from dislocating because of the friction of transmission shaft.
Described upper cover plate is provided with abat-vent, and during weight up-downgoing, abat-vent is opened, and reduces the air resistance of weight.
Supervisor's soldering member in described tup portion is provided with air hole, reduces air resistance during weight up-downgoing.
Compared with prior art the beneficial effects of the utility model
The utility model hardness measurement is accurate, and can reduce equipment damage, easy to use, the overall volume of device also reduces further, and product is more durable, and the operability of product strengthens, operating mode applicatory also horn of plenty more.
