And the fixing plate 471 may be fixed to the top of the mounting portion 12 by means such as screw connection. In order to assemble the second connection part 413, a mounting hole 4711 may be formed in the middle of the fixing plate 471, and a pivot hole 4131 may be formed in the second connection part 413, so that the connection bolt 472 may pass through the mounting hole 4711 and the pivot hole 4131 in sequence, and then may be rotatably locked to the top of the fixing plate 471 together with the first nut 473.
The first return bolt 474 and the second return bolt 475 may be disposed at two sides of the first nut 473 and fixed to the second connecting portion 413 and the fixed plate 471, respectively, and the return spring 46 may include a coil 461, a first bending rod 462, and a second bending rod 463, where the coil 461 is rotatably sleeved on the second return bolt 475 and two ends of the coil 461 are connected to two ends of the first bending rod 462 and the second bending rod 463, respectively, and a first rotating position 464 and a second rotating position 465 rotatable around the first nut 473 and the first return bolt 474 are formed between the first bending rod 462 and the second bending rod 463, respectively, so that the return spring 46 may be rotated by using the second return bolt 475 fixed to the fixed plate 471 as a pivot, and a rotation amplitude of the return spring may be limited by the first rotating position 464 and the second rotating position, so that the adjustment of the first rotating position 464 and the second bending rod 463 may be crossed with each other to adjust the relative rotation amplitude of the return spring 46, thereby enabling the adjustment of the rotation amplitude of the return spring 46. At the same time, the supporting arm 41 can also be automatically returned by the adjusting spring 44, so that the guide wheel 43 can be adapted to different steering angles at any time.
In order to increase the strength of the return spring 46, the coil 461, the first bending rod 462, and the second bending rod 463 constituting the return spring 46 may be integrally formed, for example, a steel wire or other material having a certain strength may be used, and the return spring 46 may be formed by bending, so that the cost of the return spring 46 may be reduced.
Further, a second nut 477 and a first washer 4771 may be further added to the locking member 47 and sleeved on the connecting bolt 472, and the second nut 477 may be screwed with the connecting bolt 472 to lock the first washer 4771 on the first nut 473, so as to limit the return spring 46 between the first washer 4771 and the fixing plate 471, so as to avoid displacement of the return spring 46 during adjustment, thereby improving adjustment accuracy.
Preferably, a buffer space 13 communicating with the fixing plate 471 may be provided in the mounting portion 12 along the length direction of the connection bolt 472, so that the edge of the fixing plate 471 may be fixed to the edge of the top of the mounting portion 12 to overhead the fixing plate 471, thereby playing a certain elastic role.
In order to avoid the support arm 41 from swinging too much, for example, a limit bolt 476 may be additionally provided in the locking member 47, and an arc-shaped limit hole 4712 may be provided in the fixing plate 471, so that after the assembly, the limit bolt 476 may pass through the limit hole 4712 and be connected with the second connection portion 413, so that the limit bolt 476 may swing along with the second connection portion 413, but the movement of the limit bolt 476 is limited in the limit hole 4712, and thus, the maximum swing of the support arm 41 may be well controlled through the second connection portion 413.
In order to improve the service life of the support arm 41, a plane bearing 478 and a deep groove ball bearing 479 may be additionally provided in the locking member 47, and the plane bearing 478 may be disposed at the bottom of the fixing plate 471, and the deep groove ball bearing 479 may be disposed on the plane bearing 478, where the plane bearing 478 and the deep groove ball bearing 479 are pivotally engaged with the connection bolt 472, so that the upward thrust of the guide wheel 43 may ultimately act on the plane bearing 478 and the deep groove ball bearing 479, thereby improving the service life of the support arm 41. Further, a second spacer 4772 may be added, and the second spacer 4772 may be sleeved on the connecting bolt 472 so as to be located between the fixing plate 471 and the planar bearing 478, so as to reduce wear.
Furthermore, the connection points of the support arms 41 of the two guide mechanisms 4 to the frame 1 may be located on the plane of the drive wheel 3. Thus, when the shuttle machine 100 travels straight along the cableway 200, the adjusting springs 44 of the guide mechanism 4 are compressed due to the relationship of the shuttle machine 100, so that the respective guide wheels 43 are abutted against the cableway 200 supported by the brackets and travel straight along the cableway 200 together with the driving wheels 3. While the shuttle 100 is steered along the cableway 200, the shuttle 100 can naturally adjust the angle through the guide wheels 43 in the two guide mechanisms 4, so that the shuttle 100 can still keep running smoothly. After the steering is finished, the guide wheel 43 can be reset under the cooperation of the adjusting spring 44 and the supporting arm 41, and can stably run on the same straight line with the driving wheel 3.
In addition, when the shuttle machine 100 in this embodiment passes over the cableway 200 corresponding to the bracket, since the overall mass of the shuttle machine 100 is large and the relative inertial impact force is also large, the driving wheel 3 receives an upward lifting force and instantaneously breaks away from the cableway 200, accordingly, the adjusting springs 44 of the two guiding mechanisms 4 rebound, so that the corresponding two guiding wheels 43 still contact the cableway 200, and since the connection points of the supporting arms 41 of the two guiding mechanisms 4 and the frame 1 are all located on the plane of the driving wheel 3, the driving wheel 3 can be ensured to naturally drop down to the cableway 200 and continue to run, so as to prevent the shuttle machine 100 from breaking away from the track, so that the shuttle machine 100 can run smoothly on the cableway 200, and the risk of derailing the shuttle machine 100 can be further reduced.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
