Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
In embodiments of the invention, where the context requires otherwise, the use of directional terms such as "upper, lower, top and bottom" is generally intended in the orientation shown in the drawings or the positional relationship of the various components in a vertical, vertical or gravitational orientation.
The invention will be described in detail below with reference to exemplary embodiments and with reference to the accompanying drawings.
As shown in fig. 1 to 3, a first exemplary embodiment of the present invention provides a telescopic mechanism adjustment system, which mainly includes a telescopic mechanism, a first tilt sensor 3, a second tilt sensor 4, and an anti-deformation driving mechanism.
The telescopic mechanism comprises a first straight line extension structure 1 and a second straight line extension structure 2 which are connected in a telescopic mode, for example, the first straight line extension structure 1 can be integrally inserted into the second straight line extension structure 2, or the second straight line extension structure 2 can be integrally inserted into the first straight line extension structure 1, therefore, when the telescopic mechanism extends or shortens, the first straight line extension structure and the second straight line extension structure correspondingly move away from or close to each other, and therefore the overall length of the telescopic mechanism can be adjusted. It can be seen that when the telescopic mechanism is bent and deformed, the inclination of the first linear extension structure 1 and/or the second linear extension structure 2 can be adjusted, so that the whole straightness of the telescopic mechanism is adjusted, and the bending deformation is eliminated. In addition, the telescopic mechanism can be arranged in the arm support, so that the arm support can be driven to synchronously extend and retract.
The first tilt angle sensor 3 can measure a first tilt angle between the first linearly extending structure 1 and a preset reference plane, for example, the horizontal plane can be set as the preset reference plane, and then the first tilt angle sensor 3 can measure an included angle between the first linearly extending structure 1 and the horizontal plane as the first tilt angle. Further, the first tilt sensor 3 may be configured to perform real-time measurements, thereby enabling real-time acquisition of the first tilt data.
The second inclination sensor 4 is capable of measuring a second inclination between the second linearly extending structure 2 and the predetermined reference plane, for example, by setting the horizontal plane as the predetermined reference plane, the second inclination sensor 4 is capable of measuring an angle between the second linearly extending structure 2 and the horizontal plane as the second inclination. Further, the first tilt sensor 3 may be configured to perform real-time measurements, thereby enabling real-time acquisition of the first tilt data.
In addition, under the driving of the reverse deformation driving mechanism, the first straight extension structure 1 and/or the second straight extension structure 2 can generate reverse deformation displacement, and the first inclination angle and/or the second inclination angle are/is changed in the displacement process, so that the inclination angle difference value of the first inclination angle and the second inclination angle can be kept within a preset allowable deviation range, and the straightness of the telescopic mechanism can be confirmed to meet the operation requirement. For example, when the telescopic mechanism shown in fig. 1 is subjected to bending deformation, the reverse deformation driving mechanism may directly drive the first linearly extending structure 1 to perform reverse deformation displacement, and during the displacement, the second linearly extending structure 2 may be kept relatively still, at which time the first inclination angle changes, and the second inclination angle does not change, so as to adjust the inclination angle difference between the first inclination angle and the second inclination angle to be within the preset allowable deviation range. Of course, the reverse deformation driving mechanism may also directly drive the second linear extension structure 2 to perform reverse deformation displacement, or simultaneously drive the first linear extension structure 1 and the second linear extension structure 2 to perform reverse deformation displacement.
According to the technical scheme, the first linear extension structure and the second linear extension structure of the telescopic mechanism are in telescopic connection, so that the overall length of the telescopic mechanism can be adjusted, meanwhile, under the detection of the first inclination angle sensor and the second inclination angle sensor, the first inclination angle and the second inclination angle between the first linear extension structure and the preset reference plane and the second linear extension structure and the preset reference plane can be obtained, whether the telescopic mechanism is integrally deformed can be judged according to the deviation degree of the inclination angle difference value of the two inclination angles and the preset allowable deviation range, and in addition, under the driving of the anti-deformation driving mechanism, the first linear extension structure and/or the second linear extension structure can be displaced on the amplitude-variable plane to eliminate bending deformation, so that the linearity of the telescopic mechanism is adjusted, good service performance of the telescopic mechanism is kept, the service life of the telescopic mechanism is prolonged, and the operation safety is improved. When the mechanism and the controller work cooperatively, the start-stop time of the anti-deformation driving mechanism can be automatically confirmed by utilizing the inclination angle information detected by the first inclination angle sensor and the second inclination angle sensor, so that the linearity of the telescopic mechanism can be automatically adjusted.
In one embodiment, the reversible deformation driving mechanism comprises the reversible deformation power device 5, in particular, the reversible deformation power device 5 can perform a telescopic action, and the reversible deformation driving mechanism can directly drive the first straight line extension structure and/or the second straight line extension structure to generate the reversible deformation displacement through the telescopic action of the reversible deformation power device 5. For example, without adding other transmission mechanisms, the reverse deformation power device 5 is arranged between a support structure (such as a boom base plate, not shown in the figures) and the telescopic mechanism to directly contact with the support structure and the telescopic mechanism, so as to drive the part of the telescopic mechanism to generate reverse deformation displacement and adjust the linearity of the whole telescopic mechanism. Therefore, the arrangement is favorable for simplifying the structure of the reversible deformation driving mechanism and reducing the production cost.
Further, the reverse deformation power device 5 comprises a device body 51 and a movable rod 52, wherein the device body 51 may be formed with an insertion through hole, such that the movable rod 52 may be movably inserted into the device body 51, and thereby the device body 51 may drive the movable rod 52 to move telescopically along the insertion through hole. In addition, the reverse deformation driving mechanism further comprises a reverse deformation supporting block 6 which is arranged at one end of the movable rod 52 which is not inserted into the device base body 51, and the reverse deformation supporting block 6 can move back and forth along the expansion direction of the movable rod 52 under the driving of the movable rod 52. Referring to fig. 2, the counter-deformation support block 6 may be disposed between one end of the movable rod 52 and a support structure (e.g., a boom base plate) such that the counter-deformation support block 6 may directly contact the support structure, thereby performing a thrust conduction function, and when the movable rod 52 extends and moves, the counter-deformation support block 6 is in pressure contact with the support structure, such that the device base 51 obtains a reaction force, thereby driving the telescoping mechanism to generate a counter-deformation displacement.
In other embodiments, the reversible deformation power device 5 may be configured to directly push the telescoping mechanism to generate the reversible deformation displacement through the telescopic movement of the movable rod 52 without using the reaction force of the movable rod 52, and at this time, the reversible deformation support block 6 connected to the movable rod 52 is in direct contact with the telescoping mechanism for transmitting the thrust to the telescoping mechanism to generate the reversible deformation displacement. Furthermore, the contact surface contour of the counter-deformation support block 6 can be adapted, for example, the contact surface of the counter-deformation support block 6 can be configured to be flush with the plane of the boom base plate or configured to be matched with the end contour of the telescopic mechanism, so that the telescopic mechanism can be pushed more stably. Furthermore, the reversible deformation supporting block 6 can be made of elastic materials, so that elastic contact with the arm support base plate or the telescopic mechanism is facilitated, and the contact surface of each component can be effectively protected.
In order to further improve the pushing stability of the reverse deformation power device 5, the device base body 51 and the telescoping mechanism can be fixed to each other. For example, referring to fig. 2, the device base 51 is fixedly connected to the first linear extending structure 1, and when the movable rod 52 pushes the boom base plate, the device base 51 receives a reverse thrust at the same time, and further drives the first linear extending structure 1 to generate a reverse deformation displacement, so that the displacement process is stable and smooth, and the reverse deformation effect can be improved. Obviously, the device base 51 is not limited to be fixedly connected with the first linear extending structure 1, and in other embodiments, the device base 51 may be fixedly connected with the second linear extending structure 2, so that when a reverse thrust is generated, the device base 51 can drive the second linear extending structure 2 to perform a reverse deformation displacement. In addition, two device substrates 51 may be respectively fixed to the first linear extension structure 1 and the second linear extension structure 2, and then the two devices are driven to perform reversible deformation displacement simultaneously, so as to achieve the technical effects of improving the displacement stability and the like.
In an embodiment, the reversible deformation driving mechanism further comprises a guide support 7, the reversible deformation support block 6 is in sliding fit with the guide support 7, during the sliding process, the guide support 7 can limit the reversible deformation support block 6, so that the reversible deformation support block 6 can be accurately displaced along the expansion and contraction direction of the movable rod 52, referring to fig. 2, the guide support 7 can be fixedly connected with the expansion and contraction mechanism, the guide to the reversible deformation support block 6 can be realized, meanwhile, the stability of the pushing and pressing process is improved, and the influence on the structural reliability caused by the deviation of the thrust direction is prevented. In addition, the guide support 7 may also be fixedly connected with the arm support, or fixed by other structural members, and the above technical effects may also be achieved.
In one embodiment, the guide support 7 is fixedly connected to the telescopic mechanism. For example, the guide support 7 can be fixedly connected to the first linearly extending structure 1 or the second linearly extending structure 2, as shown in fig. 2 in the case of fixedly connecting the guide support 7 to the first linearly extending structure 1, and in addition, in the case of providing two counter-deformation driving mechanisms, the two guide supports 7 can be fixedly connected to the first linearly extending structure 1 and the second linearly extending structure 2, respectively. Therefore, through the fixed connection of the guide support 7 and the telescopic mechanism, the reversible deformation support block 6 can be displaced under the guidance of the guide support 7 no matter under the condition that the device base body 51 is fixed on the telescopic mechanism or the condition that the device base body is fixed on the boom base plate, so that the telescopic mechanism can be pushed reversely or directly pushed to perform reversible deformation displacement, and the adaptive adjustment of the installation position of the device base body 51 is facilitated.
When the telescopic mechanism is bent and deformed, the displacement value generated at the end part of the telescopic mechanism is relatively large, so that the reverse deformation driving mechanism can be arranged at one end of the first straight line extension structure 1, which is not connected with the second straight line extension structure 2, specifically, the device base body 51 can be fixed at the end part, or the reverse deformation supporting block 6 is directly contacted with the end part, so that the end part can be directly driven to perform reverse deformation displacement, and further, the whole first straight line extension structure 1 can be driven to perform reverse deformation displacement, therefore, the pushing process can be more labor-saving, and the regulation effect of reverse deformation can be improved. Further, the reverse deformation driving mechanism may be provided at the end of the second linearly extending structure 2 to which the first linearly extending structure 1 is not connected, or two reverse deformation driving mechanisms may be provided at the two ends of the first linearly extending structure 1 and the second linearly extending structure 2 to which the first linearly extending structure 1 is not connected, respectively, and similarly, both of these two arrangements can achieve the above-described technical effects.
In one embodiment, the first tilt sensor 3 may be disposed at an end of the first linearly extending structure 1 to which the second linearly extending structure 2 is not connected, and the second tilt sensor 4 may be disposed at an end of the second linearly extending structure 2 to which the first linearly extending structure 1 is not connected. By the arrangement, the anti-deformation displacement effects of the first straight line extension structure 1 and the second straight line extension structure 2 can be fed back visually in real time through the values of the first inclination angle and the second inclination angle measured by the two sensors, and in addition, when the inclination angle difference value of the first inclination angle and the second inclination angle is adjusted to be within the preset allowable deviation range, the telescopic mechanism can be ensured to be restored to the preset linearity, so that the anti-deformation driving mechanism can be confirmed to complete the anti-deformation driving operation, and the adjustment accuracy can be improved.
Further, in order to enable the reverse deformation driving mechanism to automatically execute the driving action according to the inclination difference, the telescopic mechanism adjusting system further comprises a controller (not shown in the drawings) for controlling the reverse deformation driving mechanism, specifically, the controller can be respectively communicated with the first inclination sensor 3, the second inclination sensor 4 and the reverse deformation driving mechanism, and is configured to control the reverse deformation driving mechanism to act when the inclination difference exceeds the preset allowable deviation range until the inclination difference does not exceed the preset allowable deviation range. For example, when the telescopic mechanism is subjected to bending deformation, the first inclination angle sensor 3 and the second inclination angle sensor 4 respectively send a first inclination angle data signal and a second inclination angle data signal to the controller, the controller can judge that the inclination angle difference value exceeds a preset allowable deviation range through analysis, and then can send a starting signal to the reverse deformation power device 5 immediately, so that the reverse deformation power device 5 is controlled to start driving action, the telescopic mechanism is driven to generate reverse deformation displacement, the inclination angle difference value is finally returned to the preset allowable deviation range, and at the moment, the controller sends a stopping signal to the reverse deformation power device 5 to control the reverse deformation power device to stop driving action, so that the bending deformation of the telescopic mechanism can be eliminated, the automatic adjustment linearity is realized, the adjustment accuracy and the reliability are improved, and the operation safety is ensured.
