The features and properties of the present invention are described in further detail below with reference to examples.
as shown in fig. 1, the axial load detection device of the slewing bearing includes a sensor mounting base 3 and a plurality of displacement sensors 4, the sensor mounting base 3 is an annular base, and a ring body corresponding portion 32 is provided on the sensor mounting base 3; the displacement sensors 4 are mounted on the ring body corresponding portion 32, and are uniformly spaced along the ring body corresponding portion 32 in the circumferential direction. Taking the detection of the axial load of the turntable bearing of the shield tunneling machine as an example, when the shield tunneling machine is used, the sensor mounting base body 3 is fixed on the inner ring 2 of the turntable bearing, the ring body corresponding part 32 and the outer ring 1 of the turntable bearing are arranged at intervals along the axial direction of the turntable bearing, and the axial displacement of the outer ring 1 is detected through the displacement sensor 4, so that the axial displacement between the outer ring 1 and the inner ring 2 of the turntable bearing is obtained.
Specifically, the turntable bearing is a three-row roller type turntable bearing, the outer ring 1 of the turntable bearing is provided with a threaded hole 11, the inner ring 2 of the turntable bearing is provided with an inner ring connecting hole 21 serving as a ring body connecting hole, and the sensor mounting base body 3 is provided with a base body mounting hole 31.
When the axial load detection device of the turntable bearing is installed on the shield machine, the sensor installation base body 3 is fixedly connected with a bearing base of the shield machine through a fastener penetrating through the inner ring connecting hole 21 and the base body installation hole 31; the outer ring 1 of the turntable bearing is fixedly connected with a cutter head of the shield tunneling machine through a screw penetrating through the threaded hole 11. When the turntable bearing works, the teeth 12 arranged on the outer ring 1 are meshed with the gear, and the outer ring 1 is driven to rotate through the gear.
The inner diameter of the sensor mounting base 3 is equal to the inner diameter of the inner ring 2, and the position of the inner ring connection hole 21 is equal to the position of the axial load detection device without the turntable bearing, so that the sensor mounting base 3 and the inner ring 2 of the turntable bearing are fixed to the bearing base of the turntable bearing at the same time, and the axial load detection device of the turntable bearing is mounted between the turntable bearing and the bearing base without changing the structures of the inner ring 2 and the bearing base.
When the shield machine performs tunneling operation, the reaction force of the propelling force in the propelling process of the shield machine is transmitted to the turntable bearing and is expressed in the form of axial load. The deformation of the raceway of the turntable bearing causes the outer ring 1 and the inner ring 2 to generate axial displacement, an axial load detection device of the turntable bearing is arranged between the turntable bearing and a bearing base on the shield machine, the propulsive force is expressed as the axial displacement between the outer ring 1 and the inner ring 2, and the axial load of the turntable bearing under the displacement can be correspondingly obtained through a displacement value detected by the displacement sensor 4.
Specifically, after an axial load detection device of the turntable bearing and the turntable bearing are assembled, the turntable bearing is installed on a loading device, simulation experiments are carried out according to actual working conditions, wherein simulation of rotating speed, temperature and the like is included, the loading device loads a specific axial load F on the turntable bearing, displacement values under all axial loads are measured through all displacement sensors 4 and are used as databases of the turntable bearing, the databases of all the turntable bearings are independent and different, one simulation experiment needs to be carried out when the same turntable bearing reaches a checking period and after parts are disassembled, inspected and replaced, internal data are calibrated and updated once, and therefore the databases are guaranteed to be real and effective. When the turntable bearing works, the displacement value of each displacement sensor 4 is compared with the data in the database, and the axial load currently born by the turntable bearing can be correspondingly obtained. If the turntable bearing is detected to be under the limit load, the working parameters of the shield tunneling machine can be adjusted through manual operation, the load is reduced, the loss of the turntable bearing is reduced, and the service life is prolonged.
Taking the number of displacement sensors 4 as an example of 36, one displacement sensor 4 is installed every 10 ° in the circumferential direction of the sensor mounting base 3, and the resolution of each displacement sensor 4 is 1 μm. During the propelling of the shield machine, the displacement values are recorded in real time through 36 displacement sensors 4, and the axial load of the turntable bearing is obtained correspondingly according to the displacement values of the displacement sensors 4. Of course, in other embodiments, the number of displacement sensors may be increased or decreased as appropriate according to the radial dimension of the bearing to be detected and the detection accuracy requirement.
When the turntable bearing bears the overturning moment, that is, when the axial load is unevenly distributed in the circumferential direction of the turntable bearing, the overturning angle and the overturning moment of the turntable bearing can be obtained according to the displacement values detected by the displacement sensors 4, for example, the overturning angle is determined according to the installation positions of the sensors, the angle value of each displacement sensor is calibrated on the turntable bearing by laser typing according to the installation positions of the displacement sensors, any point is 0 °, when the displacement of the displacement sensor at 30 ° is the maximum, the force bearing point of the turntable bearing is at the position of 30 ° or at the position of 210 ° opposite to 30 °, the positive or negative displacement is determined according to the calibration, and the overturning moment can multiply the axial load corresponding to the maximum deformation point by the distance from the installation position of the sensor to the center of the turntable bearing.
The axial load detection device of the turntable bearing can detect the axial load of the shield machine during operation in real time on line, solves the problem that the axial load or the overturning moment exceeds the mechanical load in the propelling process of the shield machine to cause equipment damage, and plays roles of defense and early warning.
The device only increases the mounting height of the turntable bearing without changing the mounting size and structure of the original turntable bearing, and can meet the structural requirements of the shield tunneling machine. As a specific example, the axial dimension of the sensor mounting base body 3 is set to 40mm in order to minimize the influence of the sensor mounting base body 3 on the mounting height of the turntable bearing while satisfying the structural strength and the use requirements of the sensor mounting base body 3. Of course, in other embodiments, the axial dimension of the sensor mounting base may be set to other values depending on its structural strength and use requirements.

Between carousel bearing's inner circle 2 and sensor installation base member 3 in this embodiment, through different fastener difference fixed connection between sensor installation base member 3 and the bearing base, conveniently install sensor installation base member 3 respectively with carousel bearing, bearing base fixed connection, however, need change bearing base's among the prior art structure.
