DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-4, the utility model provides a technical solution:

A spoke tensile deformation detection device comprises a base 1, a rotation detection mechanism 3 is arranged on the top of the base 1, and a mounting mechanism 2 is arranged on the top of the base 1 for lifting and mounting spokes on the wheel, wherein the mounting mechanism 2 comprises:

The lifting assembly 21 is arranged on the top of the base 1, and comprises a lifting cylinder 211 fixedly mounted on the top of the base 1, a limit rod 212 fixedly mounted inside the lifting cylinder 211, a rotating worm gear 213 is rotatably mounted on the top of the inner cavity of the lifting cylinder 211, and a threaded lifting column 214 is rotatably installed through the internal thread of the rotating worm gear 213, and the rotating worm gear 213 rotates to drive the threaded lifting column 214 to rise and fall, so that the wheel can be easily lifted or lowered by the lifting and lowering of the wheel by the adapting placement assembly 23, which makes the installation and removal of the spokes more convenient, which not only improves the work efficiency, but also reduces the labor intensity of the operator;

The transmission assembly 22 is disposed on the top of the base 1 and is used to provide kinetic energy to the lifting assembly 21;

The adapting and placing component 23 is arranged on the top of the lifting component 21 and is used to adapt to wheels of different specifications and sizes.

In this embodiment, the lifting assembly 21 also includes a slide groove 215 opened inside the threaded lifting column 214, and the limiting rod 212 is adapted to be installed inside the slide groove 215. When the threaded lifting column 214 rises and falls, the limiting rod 212 is stuck in the inside of the slide groove 215, thereby limiting the threaded lifting column 214 and preventing the threaded lifting column 214 from rotating.

In this embodiment, the transmission assembly 22 includes a fixed frame 221 fixedly installed on the top of the base 1, and a rotating shaft 222 is installed inside the fixed frame 221, and the right end of the rotating shaft 222 is movably penetrated through the right plate of the lifting cylinder 211 and a handwheel 224 is fixedly installed. A worm 223 is fixedly sleeved on the outer side of the rotating shaft 222, and the worm 223 is meshed with the rotating worm wheel 213. The user rotates the handwheel 224 to drive the rotating shaft 222 and the worm 223 to rotate synchronously. At this time, the worm 223 meshes with the rotating worm wheel 213 to realize the synchronous rotation of the rotating worm wheel 213, thereby allowing the lifting assembly 21 to operate.

In this embodiment, the adaptation placement component 23 includes a mounting frame 231 fixedly mounted on the top of the threaded lifting column 214, and the left and right plates of the mounting frame 231 are threadedly rotated to penetrate and install a threaded column 232, one end of the threaded column 232 is movably installed with a connecting block 233, and one end of the connecting block 233 is fixedly installed with an arc block 234. The user rotates the threaded column 232 to make the two arc blocks 234 move toward or in the opposite direction, thereby adjusting the distance between the two arc blocks 234 to adapt to wheels of different specifications and sizes, and spokes of different sizes are adapted to different wheels. Therefore, this device avoids the need to replace different placement devices when changing wheels.

In this embodiment, the left and right plates of the mounting frame 231 are both movably penetrated by the limiting column 235, and one end of the limiting column 235 is fixedly connected to the connecting block 233, so as to limit the connecting block 233 when it moves to prevent the position of the connecting block 233 from being offset.

Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

During operation, the user first rotates the threaded rotating column 232 according to the specifications of the wheel, so that the two arc blocks 234 move toward or away from each other, and adjusts the distance between the two 234 to a distance suitable for wheel placement. The user then rotates the hand wheel 224 to drive the rotating shaft 222 to rotate synchronously with the worm 223. At this time, the worm 223 engages with the rotating worm wheel 213 to cause the rotating worm wheel 213 to rotate synchronously. Then, the rotating worm wheel 213 rotates to drive the threaded lifting column 214 to rise and fall. The wheel is lifted and lowered by the adapter placement component 23. When the wheel is adjusted to a suitable installation position, the wheel is installed on the rotating shaft of the rotation detection mechanism 3 through the spokes, and then the wheel is rotated. At this time, the detection mechanism of the rotation detection mechanism 3 detects the wheel and thus detects the state of the spokes.
