Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyester filament fiber production technology, and specifically to a drive wheel transmission locking mechanism for a ceiling-mounted trolley. Background Technology
[0002] In the production of polyester filament fibers, material transportation between the winding and packaging processes is a critical link in the production flow. Traditional overhead trolleys have drive wheels connected to the trolley body via square pins. Due to inertia and material strength issues, these square pins can become loose or even break. This results in the yarn cake colliding with the overhead trolley during yarn dropping, causing damage to the yarn cake and paper tubes, thus affecting product quality. Furthermore, when the overhead trolley is transported to the packaging area, its instability can cause collisions with the robotic arm, resulting in the same damage to the yarn cake and paper tubes, further impacting product quality. Utility Model Content
[0003] This invention provides a locking mechanism for the drive wheel transmission of a ceiling track trolley to solve the problems of the prior art.
[0004] The objective of this utility model can be achieved through the following technical solution: a locking mechanism for the drive wheel transmission of a ceiling-mounted trolley, comprising:
[0005] A guide wheel, wherein a guide groove is provided on the outer side of the guide wheel and a rotating through hole is provided in the middle;
[0006] An expansion device is provided, comprising an outer wheel and an inner wheel. The outer wheel has a first expansion groove extending through its side end and a first trapezoidal guide surface inside. The inner wheel has a second expansion groove extending through its side end and a second trapezoidal guide surface outside. The inner wheel is disposed inside the outer wheel and locked by a locking mechanism.
[0007] In a further improvement, two sets of the first trapezoidal guide surface and the inner wheel are provided. The two sets of the first trapezoidal guide surface and the inner wheel are symmetrically arranged on both sides of the outer wheel. A locking threaded hole is provided through the side end of each set of the inner wheel. A bolt can be inserted between the locking threaded holes of the two sets of the inner wheel for connection.
[0008] In a further improvement, the locking threaded holes and bolts are provided in multiple sets.
[0009] In a further improvement, the length of the first trapezoidal guide surface is a, and the length of the second trapezoidal guide surface is b, satisfying the quantitative relationship: a>b.
[0010] In a further improvement, a through-hole for mounting is provided on the guide wheel, and the through-hole for mounting is located between the guide groove and the rotating through hole.
[0011] Compared with the prior art, this utility model has the following beneficial effects: This utility model replaces the traditional key pin connection with a tensioning device, which can adjust the tightness according to the actual state of the drive motor and drive wheel, ensuring the stability of the connection and preventing loosening. This ensures that when the winding machine and the packaging robot arm are feeding the wire onto the overhead track carriage, the overhead track carriage can maintain stability in the horizontal and vertical directions at the wire feeding point, and will not shake during wire feeding. During wire feeding, there will be no collision between the wire cake and the overhead track carriage or the packaging robot arm, thereby reducing the phenomenon of wire cake damage and paper tube damage, ensuring product quality and production efficiency.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0019] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.
[0020] Example 1
[0021] A locking mechanism for the drive wheel transmission of a ceiling-mounted trolley includes:
[0022] Guide wheel 1, the outer side of which is provided with guide groove 11 and the middle of which is provided with rotating through hole 12;
[0023] The expansion device 2 includes an outer wheel 21 and an inner wheel 22. The outer wheel 21 has a first expansion groove 211 extending through its side and a first trapezoidal guide surface 212 inside. The inner wheel 22 has a second expansion groove 221 extending through its side and a second trapezoidal guide surface 222 outside. The inner wheel 22 is disposed inside the outer wheel 21 and locked by a locking mechanism. Two sets of the first trapezoidal guide surface 212 and the inner wheel 22 are correspondingly provided. The two sets of the first trapezoidal guide surface 212 and the inner wheel 22 are symmetrically arranged on both sides of the outer wheel 21. Each set of the inner wheel 22 has a locking threaded hole 223 extending through its side. A bolt 224 can be inserted between the two sets of locking threaded holes 223 of the inner wheels 22 for connection.
[0024] like Figures 1-4 As shown, the expansion device 2 of this utility model is made entirely of high-strength steel, possessing excellent wear resistance and impact resistance. Simultaneously, the expansion groove allows the expansion device 2 to have a certain deformation capacity. During assembly, firstly, the outer wheel 21 is installed in the rotating through hole 12 of the guide wheel 1. Secondly, one set of inner wheels 22 is fitted onto the output end of the drive motor used to drive the trolley. Next, the outer wheel 21 and another set of outer wheels 21 are sequentially fitted onto the output end of the drive motor, so that the first trapezoidal guide surface 212 of the outer wheel 21 abuts against the second trapezoidal guide surface 222 of the inner wheel 22. Finally, the bolts are tightened. Bolt 224 is inserted into the locking threaded hole 223 of one set of inner wheels 22, and the front end of bolt 224 is threadedly connected to the locking threaded hole 223 of the other set of inner wheels 22. By continuously rotating bolt 224, the gap between the two sets of inner wheels 22 is reduced. During the movement of the two sets of inner wheels 22, the outer diameter of outer wheel 21 expands and the inner diameter of inner wheel 22 contracts due to the action of the first trapezoidal guide surface 212 and the second trapezoidal guide surface 222. This causes the outer side of outer wheel 21 to abut against the inner wall of rotating through hole 12, and the inner side of inner wheel 22 to abut against the output end of drive motor, thereby achieving locking installation.
[0025] This invention replaces the traditional key pin connection with a tensioning device 2, which can adjust the tightness according to the actual state of the drive motor and drive wheel, ensuring the stability of the connection and preventing loosening. This ensures that when the winding machine and the packaging robot arm are feeding the wire onto the overhead track carriage, the overhead track carriage can maintain stability in both the horizontal and vertical directions at the wire feeding point, preventing it from shaking during wire feeding. It also prevents the wire cake from colliding with the overhead track carriage or the packaging robot arm during wire feeding, thereby reducing the phenomenon of wire cake damage and paper tube damage, ensuring product quality and production efficiency.
[0026] As a further preferred embodiment, multiple sets of locking threaded holes 223 and bolts 224 are provided.
[0027] As a further preferred embodiment, the length of the first trapezoidal guide surface 212 is a, and the length of the second trapezoidal guide surface 222 is b, satisfying the quantitative relationship: a>b.
[0028] As a further preferred embodiment, the guide wheel 1 is provided with a through-hole 13, which is located between the guide groove 11 and the rotating through hole 12, to facilitate subsequent installation.
[0029] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
