Abstract
The utility model relates to a hardness testing device for a rope. The hardness testing device comprises a hardness testing device body which is provided with a sphere measuring head (1). The diameter of the measuring head (1) is 10-800mm. The hardness of the rope is determined through the vertical distance d of the concave surface of a rope sample and the diameter D of the rope, so that the hardness precision of the rope is increased.
Description
Technical field
The utility model relates to a kind of hardness test device, especially a kind of hardness test device for rope.
Background technology
Hardness is to weigh an important indicator of rope quality, therefore the hardness test device for rope is an important weaving measurement mechanism, device and test method in existing hardness test are not all suitable in rope sample, also there is no a kind of hardness test device for rope.
Summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model is to provide a kind of hardness test device for rope, is therefore beneficial to the improvement of soil and the growth of plant.
For achieving the above object, the technical scheme that the utility model is taked is: include the hardness test device body of the measuring head 1 with spherosome, the diameter of measuring head is set to 10-800mm.
By hardness test device body, measuring head is produced to constant pressure, by the parallel upper surface that will test rope sample that is pressed onto of measuring head, measure the recessed vertical range d in rope sample surface, d is the hardness absolute value of rope sample, the ratio of d and rope diameter D is the relative value of sample hardness, owing to having designed, there is the hardness test device of the measuring head with spherosome body, by the hardness to the recessed vertical range d in rope sample surface and rope diameter D definition rope, therefore improved the precision of the hardness of rope.
The utility model has designed, hardness test device body is set to include measuring head, telescoping cylinder, hydraulic control device and support, and telescoping cylinder is arranged on support, and measuring head is arranged on the telescopic end of telescoping cylinder, telescoping cylinder is set to be connected with hydraulic control device, and measuring head is set to spherosome.
The utility model has designed, and telescoping cylinder is set to the hydraulically extensible cylinder of 5-20N pressure.
In the technical program, rope sample hardness measurement index comprises absolute value and relative value, can compare the hardness level of same size and even different size rope sample simultaneously.So-called hardness is exactly that the harder thing of material opposing is pressed into its surperficial ability.According to the difference of test method and accommodation, stiffness units can be divided into many kinds such as Brinell hardness, Vickers hardness, Rockwell's hardness, micro-vickers hardness, and there is different method of testings in different units, is applicable to material or the occasion of different qualities.The measuring head 1 with spherosome is important technical characterictic, in the technical field of the hardness test device for rope, has novelty, creativeness and practicality.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Fig. 1 is first embodiment of the present utility model, illustrate by reference to the accompanying drawings the present embodiment, include measuring head 1, telescoping cylinder 2, hydraulic control device 3 and support 4, telescoping cylinder 2 is arranged on support 4, measuring head 1 is arranged on the telescopic end of telescoping cylinder 2, telescoping cylinder 2 is set to be connected with hydraulic control device 3, and measuring head 1 is set to spherosome.
In the present embodiment, the diameter of measuring head 1 is set to 10mm.
In the present embodiment, telescoping cylinder 2 is set to the hydraulically extensible cylinder of 5-20N pressure.
The size of this hardness test device measuring head 1 rope impression, thereby the hardness of definite rope sample.Proving installation comprises that a specification is diameter 10mm, weight is the measuring head 1 of 0.5Kg, when rope hardness is tested, by the parallel upper surface that will test rope sample that is pressed onto of measuring head 1, pressure head contacts with samples vertical, perpendicular to test face, apply the power of pressure head own wt, shock and vibration do not have in afterburner process, until test force remains on 20-30 second on sample, take off pressure head, measure the recessed vertical range d in rope sample surface, d is the hardness absolute value of rope sample, the ratio of d and rope diameter D is the relative value of sample hardness, d and D are less, surface rope sample hardness is larger, this hardness test device is applicable to the rope sample of 3-30mm, for rope sample diameter, be greater than the sample of 30mm, can increase pressure head weight or on pressure head, apply the constant power of 5-20N.
Second embodiment of the present utility model, the diameter of measuring head 1 is set to 800mm.
The 3rd embodiment of the present utility model, the diameter of measuring head 1 is set to 400mm.
The 4th embodiment of the present utility model, the diameter of measuring head 1 is set to 600mm.
The 5th embodiment of the present utility model, the diameter of measuring head 1 is set to 20mm.
The utlity model has lower feature:
1, owing to having designed the hardness test device body that has the measuring head 1 with spherosome, by the hardness to the recessed vertical range d in rope sample surface and rope diameter D definition rope, therefore improved the precision of the hardness of rope.
2, owing to having designed measuring head 1, telescoping cylinder 2, hydraulic control device 3 and support 4, measuring repeatability is good, easy to operate.
3, owing to having designed telescoping cylinder 2 and hydraulic control device 3, ergometry setting accuracy is high, and Automatic survey degree is high.
4, this hardness test device is measured the size of rope impression, thereby determines the hardness of rope sample, simple to operation.
5, the cylindrical pressure head that diameter 10mm, weight are 0.5Kg is parent, and the pressure head power that applies that as the case may be can be specifically flexible, has expanded rope hardness test scope, applied range.
Therefore 6,, owing to having designed absolute value and the relative value of rope hardness number, not only can compare the size of same size rope hardness, and can compare the rope hardness level of different size size, the very big feasibility that has improved this device.
In the hardness test device technical field for rope; Every hardness test device body that includes the measuring head 1 with spherosome, the diameter of measuring head 1 is set to the technology contents of 10-800mm all in protection domain of the present utility model.
