Description

Technical Field

[0001] The utility model relates to the technical field of a walking rail vehicle for lifting stage entertainers, in particular to an elastic automatic shrinking wheel. Background Art

[0002] When the aerial performers on the stage are raised or lowered, the driving motor on the walking track vehicle controls the winding drum to retract and release the suspension rope to drive the performers to rise or fall.

[0003] However, the existing walking track vehicle lacks an elastic tensioning mechanism for retracting and releasing the suspension rope. Since the performer is performing while being lifted or lowered, the suspension rope will have a relatively large swing amplitude during the two processes of retracting or releasing the rope, causing the suspension rope to easily fall out of the reel groove during the process of reeling or releasing the rope, thereby causing the performer to fall suddenly, posing a greater risk to the performance. Utility Model Content

[0004] The utility model aims to provide an elastic automatic retractable wheel to solve the problem of lack of an elastic tensioning mechanism for retracting and releasing a suspension rope on a traveling rail vehicle proposed in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] The elastic automatic retractable wheel comprises a vehicle plate of a walking rail vehicle, a driving motor is installed on the bottom of the vehicle plate, a winding drum is fixedly connected to the output shaft of the driving motor, a fixing plate is fixedly connected to the left side of the bottom of the vehicle plate, and a guide wheel and an elastic tensioning mechanism are sequentially installed on the lower right side of the fixing plate from top to bottom;

[0007] The elastic tensioning mechanism is composed of a fixed rod, a sleeve rod, a spring, a connecting plate and a fixed pulley. The left end of the fixed rod is mounted on the fixed plate. The fixed rod is inserted into the sleeve rod. The sleeve rod is sleeved with the spring. The right end of the sleeve rod is fixedly connected to the connecting plate. One end of the spring is fixedly connected to the connecting plate, and the other end is fixedly connected to the fixed plate. The fixed pulley is mounted on the right side of the connecting plate.

[0008] A hanging rope is wound around the winding drum, and the other end of the hanging rope is passed downwardly around the guide wheel and the fixed pulley in sequence to hang the performer.

[0009] When in use, the elastic tensioning mechanism moves left and right as the suspension rope swings. At this time, the sleeve rod moves left and right on the fixed rod, and the spring stretches or contracts, so that the suspension rope is always stable in the fixed pulley, and the suspension rope always follows the guide wheel and is then wound around the winding drum, making the suspension rope more stable during the winding or releasing process and will not fall off the drum.

[0010] Furthermore, the guide wheel is located below the winding drum.

[0011] Furthermore, the fixing plate is located on the left side of the driving motor, so that the guide wheel and the elastic tensioning mechanism on the fixing plate can be located below the winding drum.

[0012] Furthermore, a limiting slot is provided in the sleeve rod, and a limiting plate is fixedly connected to the right end of the fixed rod. The limiting plate is located in the limiting slot to prevent the suspension rope from shaking too much and causing the sleeve rod to slip off the fixed rod.

[0013] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0014] The utility model adopts an elastic tensioning mechanism to move left and right with the shaking of the suspension rope, so that the suspension rope is always along the guide wheel and then wound on the winding drum. The suspension rope is more stable during the process of winding or releasing the rope and will not fall off the drum, thereby increasing the safety of the flying man during the performance.

[0023] The elastic tensioning mechanism is composed of a fixed rod 6, a sleeve rod 7, a spring 8, a connecting plate 9 and a fixed pulley 10. The left end of the fixed rod 6 is installed on the fixed plate 4, the fixed rod 6 is inserted into the sleeve rod 7, the sleeve rod 7 is sleeved with a spring 8, the right end of the sleeve rod 7 is fixedly connected to the connecting plate 9, one end of the spring 8 is fixedly connected to the connecting plate 9, and the other end is fixedly connected to the fixed plate 4, and the fixed pulley 10 is installed on the right side of the connecting plate 9;
