Abstract
The invention provides a rope tensile force testing device. The device is characterized in that a hinge pin sensor is mounted on a bracket; a signal wire is connected to the output end of the hinge pin sensor; a bearing pulley is mounted on the hinge pin sensor; guide pulleys are mounted on the bracket and positioned at two sides of the bearing pulley; when in use, a tested rope moves round the bearing pulley and the two guide pulleys; the tested rope applies a pressure to the bearing pulley during being tensioned under working, the pressure of the rope to the bearing pulley forms a shearing force for the hinge pin sensor, the hinge pin sensor acquires and records an electric signal of the shearing force and the electric signal is transmitted to a processing system through a signal wire, and then the processing system obtains the tensile force of the rope. The rope tensile force testing device is applied to the monitoring of tensile force of steel wire ropes of various cranes and mine hoists and the tensile force of bridge ropes and some device cables, in particular applied to the monitoring of the tensile force of the steel wire rope of the crane under a dynamic condition.
Description
Technical field
The present invention relates to device for measuring force, specifically a kind of rope tension proving installation.
Background technology
For wire rope and bridge rope or the cable etc. of the crane in work, mine hoist, usually need the test carrying out tension force, to guarantee the safety of producing.For measuring above-mentioned rope or cable tension force at work, utilize sensor at present more.Existing a kind of rope tension proving installation by a pulling force sensor and with its two ends respectively a hinged abutment ring form, this device for testing tensile force needs two abutment rings to be connected as a single entity with tested rope respectively in use, its exist shortcoming be:
1, when mounted, need tested rope to be divided into two-section, then by two abutment rings, device for testing tensile force be connected between two-section rope, install inconvenient; 2, sensor is stressed comparatively large at work, affects serviceable life.
Summary of the invention
The object of the present invention is to provide a kind of rope tension proving installation, this device for testing tensile force does not need to destroy tested rope when mounted, and in use its force cell of having is stressed less.
For achieving the above object, the present invention adopts following scheme: rope tension proving installation, and a support is equipped with shaft pin sensor, and the output terminal of shaft pin sensor is connected to signal wire, shaft pin sensor is equipped with a carrying pulley, a guide pulley is respectively equipped with in the both sides that support is positioned at carrying pulley.
From such scheme, when using rope tension proving installation provided by the invention, tested rope is walked around from carrying pulley and two guide pulley, tested rope at work tensioning time to carrying pulley there is pressure, the pressure of rope to carrying pulley forms shearing force to shaft pin sensor, shaft pin sensor collection also records the electric signal of this shearing force, and by signal wire by electrical signal transfer to disposal system, the tension force of rope can be drawn by disposal system.The present invention is applicable to monitoring the tension force of the wire rope of various crane, mine hoist, and monitors the tension force of bridge rope, some equipment cables, is especially applicable to crane rope tension detect in the dynamic case.
Structure of the present invention is simple, reliable, easy for installation, reasonable stress in work, when it is arranged on tested equipment, do not need to equipment and on rope do large change.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
The present invention is further illustrated below in conjunction with embodiment and accompanying drawing.
See Fig. 1, Fig. 2
Rope tension proving installation provided by the invention has support, shaft pin sensor 4 support is equipped with, the output terminal of shaft pin sensor 4 is connected to signal wire 8, shaft pin sensor 4 is equipped with a carrying pulley 3, and a guide pulley 1 is respectively equipped with in both sides support being positioned at carrying pulley 3.
In the present embodiment, support is made up of clamping plate 2 connection that two panels is positioned opposite, and carrying pulley 3 and guide pulley 1 are between two clamping plate 2.Two panels clamping plate 2 are connected by bolt 7 and nut 6.In addition, installation when using for ease of this device for testing tensile force, is fixed with a pair bearing 5, each bearing has mounting hole 5a in the bottom of each clamping plate 2.
See Fig. 1
When this device for testing tensile force uses on equipment under test, this device for testing tensile force is made to be fixed on equipment under test by bearing 5, tested rope 9 is walked around from carrying pulley 3 and two guide pulley 1, tested rope 9 at work tensioning time to carrying pulley 3 there is pressure, the pressure of rope 9 to carrying pulley 3 forms shearing force to shaft pin sensor 4, shaft pin sensor 4 gathers and records the electric signal of this shearing force, and by signal wire 8, electric signal is exported to disposal system, the tension force of rope can be drawn by disposal system.
