Description
Technical field
The present invention relates to tracked construction equipment field, particularly, relate to a kind of caterpillar block and the track load measurement mechanism with this caterpillar block, also relate to a kind of tracked construction equipment with described track load measurement mechanism.
Background technology
Creeper undercarriage is the important component part of caterpillar machinery (as the modernization such as crawler crane, development machine lifting extractive equipment), plays and bears complete machine weight and ensure the effect that body travels.Between caterpillar block, load is track-type major impetus, and crawler belt realizes winding along drive wheel and continuous laying on the ground between caterpillar block under load effect, thus reaches the various traveling demands of equipment.Limit by caterpillar machinery working environment, the service conditions of crawler belt traveling mechanism is severe, need transport on the complex road surfaces such as hard pavement highway, sandstone road, secondary road, mud ground, and climbing, turning, crossing over blockage need be possessed, get over the multiple driving mode such as gully across ditch.Between caterpillar block, load is complicated, Random dynamic loads, and different soil property road surface, different driving mode, different complete machine weight all cause load between different caterpillar blocks.Further, the uneven of road surface also can bring impact to creeper undercarriage, causes the random variation of load between caterpillar block.
Under the combined action such as dust, silt that the complicated live load of crawler belt and severe track are brought, each component of crawler belt driving system can produce various loss or damage, affects the normal traveling of traveling gear.In real work, the normal component failure form occurred has: the wearing and tearing of track pin and caterpillar block matrix, track pin and caterpillar block matrix cross that the high vibration that galling causes impacts, track pin and caterpillar block matrix cross the fracture by fatigue etc. that tooth, track pin and caterpillar block matrix are gnawed in walking that galling causes.For reducing or avoiding above-mentioned failure behaviour, need to build and be a kind ofly applicable to that crawler belt mechanical running mechanism reliability is high, the load measurement mechanism of good stability, to measure the track load in crawler travel process and load history, for the mechanical analysis of each parts, the wear-resistant of each parts (especially track pin and caterpillar block matrix) provide load data with endurance design, to guarantee the safety and reliability of creeper undercarriage.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
In the present invention, when not doing contrary explanation, the noun of locality " inside and outside " of use refers to profile inside and outside relative to each parts itself.
According to an aspect of the present invention, a kind of caterpillar block is provided, comprise caterpillar block matrix 1 and the multiple pin ears 2 being positioned at these caterpillar block matrix 1 both sides, wherein, described caterpillar block also comprises connecting device 3, described pin ear 2 is connected to described caterpillar block matrix 1 by described connecting device 3, and described connecting device 3 comprises sensing device 32, and this sensing device 32 can detect pulling force between described pin ear 2 and described caterpillar block matrix 1 and pressure.
It will be appreciated that, instant invention overcomes the technology prejudice that pin ear and caterpillar block matrix must be integrally formed, creatively caterpillar block matrix 1 and pin ear 2 are set to Split type structure, and by arranging sensing device 32 in connecting band track board substrate 1 with the connecting device 3 of pin ear 2, thus the pulling force that can realize between direct-detection pin ear 2 and caterpillar block matrix 1 and pressure, each pin ear 2 is added with the power on caterpillar block matrix 1 and can obtains load between caterpillar block, drastically increase accuracy and the reliability of result of a measurement.
Here, a connecting device 3 can be all connected on each pin ear 2, also caterpillar block matrix 1 can be connected to by a connecting device 3 by multiple pin ear 2.Preferably, each pin ear 2 all connects a connecting device 3, load total value between caterpillar block can not only be obtained like this, the load diatibution between caterpillar block can also be obtained.
Described sensing device 32 can be formed as various suitable structure, as long as the pulling force between pin ear 2 and described caterpillar block matrix 1 and pressure can be detected.As a kind of embodiment, described sensing device 32 can comprise elastic frame 321 and piezoelectrics, and described piezoelectrics are arranged in described elastic frame 321, can detect described pulling force and pressure with the distortion of described elastic frame 321.In the present invention, when elastic frame 321 under tension or pressure, will produce elastic deformation, the piezoelectrics be arranged in elastic frame 321 are out of shape with the distortion of elastic frame 321, thus the pulling force that can detect suffered by elastic frame 321 or pressure.
Described piezoelectrics can be arranged in elastic frame 321 in various suitable mode, such as, through hole 322 can be formed with in described elastic frame 321, the axes normal of this through hole 322 is in the deformation direction L of described elastic frame 321 when being subject to Tensile or Compressive Loading, described piezoelectrics are connected to the hole wall of described through hole 322 and the radial direction along described through hole 322 extends, can detect described pulling force and pressure with the cross-sectional deformation of described through hole 322.In this case, when elastic frame 321 deforms, the shape of cross section of through hole 322 changes thereupon, and the hole wall extruding of through hole 322 or the described piezoelectrics that stretch, be out of shape to make it.Here it should be noted that, elastic deformation direction is usually consistent with elastic force direction suffered by elastic body, namely, the deformation direction L of the elastic frame 321 of indication of the present invention is consistent with the direction of the pulling force suffered by elastic frame 321 or pressure, by through hole 322 being set to axes normal in the deformation direction L of described elastic frame 321, make result of a measurement more accurate.
Here, bolt can being set in the end of described piezoelectrics, by being connected on the hole wall of through hole 322 by this bolt thread, thus realizing the connection of described piezoelectrics and described hole wall.Certainly, other suitable mode (such as bonding) also can be adopted to connect described piezoelectrics and described hole wall, and the present invention is not restricted this.
