DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. The specific structures and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments set forth herein.

[0026] like Figure 1 As shown, Figure 1 A structural schematic diagram of a travel control system provided in an embodiment of the present application; a travel control system, the travel control system comprising a reference member 100, a linkage component and a measurement component, wherein:

[0027] The reference part 100 provides a relatively stable operating basis, and in different operating environments, can provide a relatively stable and adjustable reference reference outside the travel operating system, which is convenient for quickly building the travel control system and maintaining the consistency of the reference during the travel control process, thereby improving the accuracy of the control operation and reducing the difficulty of the operation.

[0028] like Figure 1 As shown, the linkage component is fixed on the reference part 100, and is used to connect the active output end and synchronously displace with the active output end in the same direction. The linkage component is detachably connected to the active output end. In different operating systems, it can be quickly synchronously connected with the active output end based on the reference part 100, and during the operation, the displacement amount and displacement direction of the active output end are synchronously fed back through the linkage component, thereby reducing the dependence on the operating system where the original active output end is located. At the same time, the displacement amount and displacement direction of the active output end are synchronized to the reference reference provided by the reference part 100.

[0029] like Figure 1As shown, the measuring component is fixed on the reference member 100, and the measuring component includes a reference member, a detection member 303 and a control member. The reference member is mounted on the reference member 100 and connected to the linkage member. The reference member can reciprocate under the displacement drive of the linkage member. The detection member 303 is arranged on the rotation path of the reference member through a base 304 at intervals, and is used to obtain the rotation data of the reference member. The control member is connected to the detection member 303. After receiving and processing the rotation data, the control member can obtain the stroke data of the active output end, synchronize the linkage member through the reference member, and feed back the displacement state of the linkage member that is displaced in the same direction and distance as the active output end through the rotation displacement of the reference member, thereby reducing space occupancy. The reference member can reciprocate for multiple times in the rotation direction, and obtain the rotation data through the detection member 303 respectively. After the control member processes the rotation data, the displacement relationship between the rotation data and the linkage member can be used to quickly process and obtain the stroke data of the active output end.

[0030] Specifically, the rotation data of the reference member may be the number of rotations or the time of average rotation.

[0031] In an optional embodiment, the working principle of the stroke control system in the present application is: the stroke control system includes a reference member 100, and a linkage component and a measuring component respectively arranged on the reference member 100, the linkage component is fixedly arranged on the reference member 100, and is used to connect the active output end, and synchronously displace in the same direction with the active output end, the measuring component includes a reference member, a detection member 303 and a control member, the reference member is mounted on the reference member 100, and is connected to the linkage component, the reference member can reciprocate under the displacement drive of the linkage component, the detection member 303 is arranged at intervals on the rotation path of the reference member, and is used to obtain the rotation data of the reference member, the control member is connected to the detection member 303, and the control member can receive and process the detection member After the rotation data is obtained, the stroke data of the active output end is obtained. During actual operation, the linkage component is connected to the active output end and displaced synchronously, and the reference part is driven to rotate back and forth synchronously. Along with the relative displacement of the reference part, the detection part 303 obtains the rotation data of the reference part, and processes the rotation data through the control part to obtain the displacement stroke data of the active output end, thereby realizing fast and convenient control operation. The linkage component is used to transfer the displacement of the active output end during the entire operation process, and then the corresponding measurement and control operations are performed on the reference part 100. On the one hand, it avoids on-site installation operations for different operating systems, improves operating efficiency, and avoids the increase of failure points and equipment costs. On the other hand, it does not rely on the stroke operation system, and the control component layout is relatively independent, which is more applicable.

[0032] like Figure 1As shown, in an optional embodiment, the linkage assembly includes a first positioning portion 201 fixed on the reference member 100, and a linkage rod 202 is movably provided through the first positioning portion 201, one end of the linkage rod 202 is used to connect the active output end, and can reciprocate axially under the support and restriction of the first positioning portion 201.

[0033] The first positioning portion 201 is fixed on the reference member 100 and supports and limits the linkage rod 202, so as to keep the linkage rod 202 in a stable reciprocating displacement in a set direction, avoid the linkage rod 202 from being offset, and improve the synchronization accuracy of the linkage rod 202 with the displacement of the active output end, thereby improving the accuracy of the control over the active output end.

[0034] like Figure 1 As shown, in an optional embodiment, the linkage assembly further includes a plurality of guide portions 203 and a guide block 204, the plurality of guide portions 203 are respectively fixed on the reference member 100 via a plurality of second positioning portions 205, and the guide portions 203 are respectively arranged parallel to the linkage rod 202, the guide block 204 is fixed on the linkage rod 202, and the guide block 204 is slidably arranged on the guide portion 203, and the displacement direction of the linkage rod 202 is constrained by the reciprocating movement of the guide block 204 on the guide portion 203.

[0035] The guide portion 203 is fixedly mounted on the reference member 100 through the second positioning portion 205, and maintains the same positioning reference as the linkage rod 202 through the reference member 100 and the second positioning portion 205. A guide block 204 is movably provided on the guide portion 203, and the direction and angle of the reciprocating movement of the guide block 204 on the guide portion 203 are jointly constrained by multiple guide portions 203. At the same time, the linkage rod 202 is connected and fixed through the guide block 204, and then the displacement accuracy of the linkage rod 202 is guided and limited by the guide portion, so as to reduce the offset wear between the linkage rod 202 and the first positioning portion 201, and further improve the operation accuracy.

[0036] like Figure 1 As shown, in an optional embodiment, the reference member includes a guide wheel 301 and a plurality of reference portions 302, and the plurality of reference portions 302 are evenly arranged along the circumferential direction on the side end surface of the guide wheel 301, and the guide wheel 301 is connected to the linkage assembly and can drive the guide wheel 301 to rotate reciprocatingly so that the reference portions 302 rotate synchronously.

[0037] A plurality of reference parts 302 are arranged on the guide wheel 301, and the synchronous displacement of the linkage rod 202 is fed back through the rotation of the guide wheel 301, thereby driving the reciprocating movement in a single direction to rotate the guide wheel 301 in the positive and negative directions. The rotation of the guide wheel 301 stably drives the synchronous rotation of the plurality of reference parts 302. When the detection part 303 is used to acquire displacement data, the plurality of reference parts 302 can shorten the detection unit, and thus the detection part 303 can acquire the corresponding displacement information more timely when the linkage rod 202 starts to move, during the displacement process, and after the displacement is completed, and thus a more accurate data reference can be obtained in the displacement state of the active output end.

[0038] like Figure 1 , Figure 2 As shown, Figure 2 A schematic diagram of the structure of some components at the detection member 303 provided in an embodiment of the present application; in an optional embodiment, the travel control system also includes a driving component, and the driving component is arranged between the reference member and the linkage component, and when the linkage component is displaced, the reference member is driven to reciprocate through the driving component.

[0039] The driving component is arranged between the reference part and the linkage component, so that the linear reciprocating motion of the linkage component drives the reciprocating rotation of the reference part through the connection of the driving component, so as to facilitate the transmission of driving force at different heights and directions, and has stronger applicability.

[0040] like Figure 1 , Figure 2 As shown, in an optional embodiment, the driving assembly includes a driven wheel 401, a guide belt 402, and a connecting block 403 fixed on the guide belt 402, the driven wheel 401 is rotatably mounted on the reference member 100, the guide belt 402 is simultaneously mounted on the guide wheel 301 and the driven wheel 401, and drives the guide wheel 301 to rotate reciprocatingly, and the connecting block 403 is detachably connected to the linkage assembly.

[0041] The driven wheel 401 and the guide wheel 301 are connected via the guide belt 402, so that the guide belt 402 is displaced synchronously with the linkage assembly via the connecting block 403, and the driven wheel 401 and the guide wheel 301 are driven to rotate in the same direction and synchronously via the flexible guide belt 402, so as to keep the displacement of the linkage assembly stably output to the guide wheel 301, thereby reducing the error margin in the intermediate driving process.

[0042] like Figure 1 , Figure 2 As shown, in an optional embodiment, a plurality of the reference portions 302 are evenly spaced and arranged, and when the guide belt 402 drives the guide wheel 301 to rotate, the rotation angle of the reference portion 302 is proportional to the displacement distance of the guide belt 402 .

[0043] Multiple reference parts 302 are arranged circumferentially at uniform intervals, so that uniform and predictable position parameters can be formed on the side wall of the guide wheel 301, and then after the detection member 303 detects the reference part 302 of the target number, the rotation angle of the guide wheel 301 can be obtained, and then the displacement of the guide belt 402 and the displacement of the linkage component can be obtained. The rotation angle of the reference part 302 is proportional to the displacement distance of the guide belt 402. The movement of the guide belt 402 synchronously drives the corresponding rotation amplitude of the reference part 302. In order to maintain the rotation accuracy of the reference part 302, the friction between the guide belt 402 and the guide wheel 301 can be adjusted by adjusting the tension of the guide belt 402 to avoid relative sliding between the guide belt 402 and the guide wheel 301 and maintain higher accuracy.

[0044] like Figure 1 , Figure 2 As shown, in an optional embodiment, the detection member 303 adopts a counting proximity switch, and when the reference part 302 moves to the target position, the detection member 303 can be triggered once.

[0045] The counting proximity switch is also called a counting sensor or a counting proximity detector, and is used to detect and count objects passing through its sensing range. During the rotation of the reference part 302, it passes through the position of the detection member 303 one by one, and is detected and identified by the detection member 303, and triggers the detection member 303 to count, and the displacement data is obtained.

[0046] like Figure 1 As shown, in an optional embodiment, the travel control system also includes at least two limit switches 501, and the limit switches 501 are fixedly mounted on the reference member 100. The limit switches 501 are used to detect the linkage assembly, and connect and control the displacement state of the active output end to limit the travel amount of the active output end.

[0047] The limit switch 501 constrains the displacement limit position of the linkage component, thereby forming a displacement range limit for the active output end, protecting the displacement stroke of the active output end, avoiding excessive displacement, and improving control reliability.

[0048] like Figure 1 As shown, in an optional embodiment, the limit switch 501 is fixed on the reference member 100 via a third positioning portion 502, and the limit switch 501 is a limit proximity switch.

[0049] The limit proximity switch is used to detect the position of the linkage component. It is fixedly installed on the reference member 100 through the limit switch 501 to determine whether the linkage component has reached a predetermined position, or to detect the extreme position of the linkage component. Specifically, the limit switch 501 is set at the end of the stroke of the linkage component or at the safety limit.
