Description
Technical field
The utility model relates to material handling technical field, particularly the anti-skidding power online testing device of a kind of haulage cradle.
Background technology
In aerial cableway design, the anti-skidding power of haulage cradle is a very important parameter, and the accuracy of this parameter directly can have influence on the safe running performance in de-hanging cable road.Existing haulage cradle anti-skidding power on-line testing scheme is: first fix rope clamp in a distance of rope-grippers rear end wire rope, with rope, rope-grippers, digital or pointer tautness meter, chain block and rope clamp are connected again, by pulling chain block to exert a force to rope-grippers, until the rope-grippers mobile data recording tautness meter on a steel cord simultaneously.But, there is following shortcoming in this measurement scheme: the 1) back of rope-grippers test stress point holding card outside, have deviation with wire rope center line, the point of fixity of chain block and the offset distance at wire rope center are larger, produce the accuracy of larger Moment Influence measurement result; 2) chain block continuity of operation is not enough, can not form the acting force of continous-stable, affect measuring accuracy; 3) measure set-up procedure complicated, time-consuming, easily cause installation operate miss; 4) the improper damage easily causing wire rope fixed by rope clamp.
Utility model content
In order to solve that existing haulage cradle anti-skidding power on-line measurement trueness error is large, measuring process is complicated and the problem such as easy damaged wire rope, the utility model provides the anti-skidding power online testing device of a kind of haulage cradle, and described device comprises pressing plate, bolt, nut, baffle plate, the axis of guide, bearing pin, pressure transducer, plain washer and bearing; Described pressing plate and bearing are fixed on the steel construction of cableway exit by bolt, nut; Described baffle plate is fixedly connected with by bearing pin with one end of the axis of guide; Described pressure transducer is fixedly connected with bearing by bolt, nut, plain washer; The other end of the described axis of guide is connected with described pressure sensor contacts with the hole on bearing through pressing plate.
Described baffle plate is U-shaped baffle plate.
Described axis of guide end is provided with semicircle clamp.
The anti-skidding power online testing device of the haulage cradle that the utility model provides, by force cell and cableway system hydraulic pressure tension force technology, directly hold in haulage cradle and wire rope longitudinal direction and close center and obtain barrier force and be delivered to pressure transducer by the axis of guide, thus directly measure the anti-skidding power numerical value of haulage cradle reality on a steel cord, structure is simple, data are accurate, measurement is convenient, to wire rope without additional injury, be convenient to regular detection, ensure that the operation that de-hanging cable road is reliable, safe.
Accompanying drawing explanation
Fig. 1 is the structural representation of the anti-skidding power online testing device of the utility model embodiment haulage cradle;
Fig. 2 and Fig. 3 is the using state schematic diagram of the anti-skidding power online testing device of the utility model embodiment haulage cradle.
Embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are further described.
See Fig. 1, the utility model embodiment provides the anti-skidding power online testing device of a kind of haulage cradle, and this device comprises pressing plate 1, bolt 2, nut 3, baffle plate 4, bearing pin 5, the axis of guide 6, pressure transducer 7, bolt 8, nut 9, plain washer 10 and bearing 11.Wherein, pressing plate 1 and bearing 11 are fixed on the steel construction of cableway exit by bolt 2, nut 3; Baffle plate 4 is fixedly connected with by bearing pin 5 with one end of the axis of guide 6; Pressure transducer 7 is fixedly connected with bearing 11 by bolt 8, nut 9, plain washer 10; The other end of the axis of guide 6 to contact with pressure transducer 7 through pressing plate 1 and the hole on bearing 11 and is connected.In actual applications, baffle plate 4 can be U-shaped baffle plate, and the end of the axis of guide 6 is provided with semicircle clamp.
See Fig. 2, before the anti-skidding power online testing device of use the present embodiment haulage cradle is measured, need this proving installation and haulage cradle assembly connection, specifically: first haulage cradle suspended carriage to be tested to be parked in cableway tensioning station (1., 2. fine strain of millet) 1. appropriate location (about 500mm) inside number beam, to remove the guide vane of the tested end of haulage cradle, anti-skidding for the present embodiment haulage cradle power online testing device is first arranged on this side 1. low level below number beam wire rope, again the axis of guide of band U-shaped baffle plate is passed from the hole pressing plate and bearing, by adjusting the upper-lower position of online testing device, the gap of two sides and wire rope about U-shaped baffle inner wall is made to keep even, 2 ~ 5mm at the bottom of wire rope lower edge distance U-shaped baffle plate groove, then by pressing plate and bearing bolt and fastening nuts, make it to be fixed on the both sides of 1. number beam, the axis of guide is withstood on the pressure transducer contact that is fixed on bearing, pressure transducer is connected with Displaying Meter by signal wire.
After by the online testing device of the present embodiment and haulage cradle assembly connection, surveying work can be carried out, detailed process is: open Displaying Meter power switch, after errorless to the inspection of this Displaying Meter, slowly open the blowdown valve of cableway tensioning system to system decompression, until haulage cradle jaw end face starts after running into U-shaped baffle plate to occur, the maximal value in reading displayed instrument slippage moment, this maximal value is the anti-skidding power of actual measurement of haulage cradle; Repeated test 3 times according to the method described above, averages as the anti-skidding power actual value of haulage cradle.
The utility model embodiment utilizes the decompression function release tensile force of cableway system Hydranlic tensioner, drives wire rope and haulage cradle to move, produces the power measuring the anti-skidding power of haulage cradle; Use de-hanging cable road main body steel construction as the support of measuring acting force, the axis of guide being provided with semicircle clamp by end is stuck in the jaw end face that haulage cradle holds conjunction wire rope, to stop the movement of rope-grippers, obtains the anti-skidding power of haulage cradle; To the resistance of haulage cradle movement be stoped to be directly delivered on pressure transducer by the axis of guide, pressure transducer be directly connected with Displaying Meter, when haulage cradle starts slippage occurs, can read the anti-skidding power that it is maximum.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
