Description
Technical field
The utility model relates to a kind of pilot system of measuring contrast cutter tooth pulling force, belong to mechanical design field.
Background technology
In dredging industry, the application of cutter suction dredger is quite general.But in the work of hog barge reamer, especially excavate in clayed soil process, reamer is because the adhesion of soil reduces work efficiency, even adheres to and cause cutter cisco unity malfunction when serious.Therefore be necessary the novel cutter tooth with visbreaking resistance reducing effect on exploitation dredging reamer, and the visbreaking resistance reducing effect of cutter tooth carried out to contrast experiment.The utility model is exactly under this demand, to have designed a kind of experimental system of measuring contrast cutter tooth pulling force.
Utility model content
For the deficiency existing in prior art, the utility model provides a kind of pilot system of measuring contrast cutter tooth pulling force.
The utility model is to realize by the following technical solutions:
A pilot system of measuring contrast cutter tooth pulling force, comprises draw-gear, test unit and measurement mechanism, and described test unit connects respectively draw-gear and measurement mechanism; Described test unit comprises trailer wagon, octagonal ring sensor, support, connecting link; Described trailer wagon connects draw-gear, described support crossbearer is in trailer wagon both sides, octagonal ring sensor is installed on described support, and the lower end of described octagonal ring sensor is connected with for the connecting link of cutter tooth to be measured is installed, and described octagonal ring sensor also connects measurement mechanism.
Above-mentioned measurement mechanism comprises data collecting instrument and dynamic resistance strain instrument, and described dynamic resistance strain instrument connects octagonal ring sensor, and the pulling force of octagonal ring sensor measurement is converted into electric signal transmission to data collecting instrument.
Above-mentioned draw-gear is the electric arc furnaces of adjustable speed, for trailer wagon provides power.
Above-mentioned connecting link has 2 at least.
The utility model compared with prior art useful effect is: a kind of experimental system of measuring contrast cutter tooth pulling force that the utility model provides, can measure the different dredging cutters tooth sizes of pulling force under the same conditions.It is simple in structure, and convenient operation is easy to use, and cost is low.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the utility model in detail;
Fig. 1 is structural representation of the present utility model.
embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
As shown in Figure 1, a kind of pilot system of measuring contrast cutter tooth pulling force, comprises draw-gear 1, test unit and measurement mechanism, and test unit connects respectively draw-gear 1 and measurement mechanism; Test unit comprises trailer wagon 2, octagonal ring sensor 4, support 3, connecting link 5; Trailer wagon 2 connects draw-gear 1, and support 3 crossbearers, in trailer wagon 2 both sides, are provided with octagonal ring sensor 4 on support 3, and the lower end of octagonal ring sensor 4 is connected with for the connecting link 5 of cutter tooth to be measured is installed, and octagonal ring sensor 4 also connects measurement mechanism.
As preferred version, above-mentioned measurement mechanism comprises data collecting instrument 7 and dynamic resistance strain instrument 6, and dynamic resistance strain instrument 6 connects octagonal ring sensor 4, and the pulling force that octagonal ring sensor 4 is measured is converted into electric signal transmission to data collecting instrument 7.
As preferred version, the electric arc furnaces that above-mentioned draw-gear 1 is adjustable speed, for trailer wagon 2 provides power.
As preferred version, above-mentioned connecting link 5 has 2 at least.
Principle of work of the present utility model is as follows: during work, by draw-gear 1, provide power, trailer wagon 2 motions; In trailer wagon 2, put into some clays and a certain amount of water, form certain hydraulic pressure.One of connecting link 5 installs the cutter tooth 9 that common cutter tooth 8, another root are installed modification or changed shape, and simulation cutter tooth moves under water, and cutter and clay just form relative motion like this; Octagonal ring sensor 4 is converted into electric signal transmission by the pulling force of measurement to data collecting instrument 7 by dynamic resistance strain instrument 6, and data collecting instrument 7 is being saved in data on notebook computer through transforming.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and instructions, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
