Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Reference Figure 1-7 The illustrated transmission coupling device for a lifting conveyor includes a base plate 1, a transfer assembly 2, a motor 3, a driven disc 4, and a drive disc 5. The transfer assembly 2 is connected to the lifting conveyor. The driven disc 4 is mounted on the shaft at the other end of the transfer assembly 2. The base plate 1 is located on one side of the transfer assembly 2. The motor 3 is mounted on the base plate 1. The drive disc 5 is slidably connected to the drive shaft of the motor 3. The drive disc 5 and the driven disc 4 are meshed with each other. In order to freely adjust the state of the drive disc 5, an adjustment mechanism is provided on the base plate 1. A connecting assembly is provided on the end face of the drive disc 5 and slidably connected to the adjustment mechanism. The connecting assembly and the drive disc 5 are detachably connected.

[0026] In one embodiment of this invention, the adjustment mechanism consists of a support rod 10 and an adjustment plate 13 symmetrically arranged with the motor 3 as the center line. A set of levers 11 are rotatably connected to the top of the support rod 10, and a set of T-shaped connecting blocks 12 are hinged to the bottom surface of the levers 11. The connecting blocks 12 are slidably connected to the connecting components. When the operator moves the levers 11, the connecting blocks 12 move accordingly and drive the slidably connected connecting components. The adjustment plate 13 has a T-shaped cross-section, and two sets of adjustment holes 14 are provided on the top surface of the adjustment plate 13. The two sets of adjustment holes 14 are centered on the support rod 10, and both sets of adjustment holes 14 can be adapted to the holes on the levers 11 (connected by pins). Depending on the production situation, the operator can easily disconnect the connection between the motor 3 and the adapter component 2 after moving the levers 11.

[0027] As one embodiment of this example, the connecting component has a set of annular grooves 51 on the end face of the drive disk 5, and a positioning groove 52 on the inner wall of the grooves 51. The positioning grooves 52 are in groups of three, and each group of positioning grooves 52 has a set of positioning components. A through hole 50 is provided on the outer wall of the drive disk 5.

[0028] The end face of the slide plate 6 is provided with a set of annular protrusions 61. The protrusions 61 are adapted to the grooves 51 so that the protrusions 61 can rotate in the grooves 51. The outer wall of the protrusions 61 is provided with positioning holes 62, and the positioning holes 62 correspond to the positioning grooves 52 and the through holes 50 in terms of position and size.

[0029] After inserting the protrusion 61 into the groove 51, after rotating it by a certain angle, the positioning hole 62 is aligned with the through hole 50. Then, the connecting bolt 9 is passed through the through hole 50 and threaded between the positioning holes 62. During the rotation of the protrusion 61, the positioning component is inserted into the positioning hole 62 to complete the initial positioning and assist in the connection between the slide 6 and the drive disk 5.

[0030] As one implementation method in this embodiment, the positioning component includes a set of positioning pins 8 slidably connected within the positioning groove 52. The outer end of the positioning pin 8 is hemispherical, and a set of springs 7 are press-fitted between the positioning pin 8 and the positioning groove 52. Through the design of the springs 7, the positioning pin 8 is constantly pushed outward. When installing the drive plate 5 and the slide plate 6, the positioning pin 8 cooperates with the positioning hole 62 to achieve initial fixation. In order to facilitate the separation of the drive plate 5 and the slide plate 6, when the springs 7 push the positioning pin 8 outward, the height of the center plane of the end of the positioning pin 8 is lower than the inlet of the positioning hole 62, so as to facilitate removal.

[0031] As one embodiment of this invention, an annular groove 60 is provided on the outer wall of the slide plate 6. The groove 60 is slidably connected to the connecting block 12, so that when the adjustment mechanism is driven, the slide plate 6 is driven to slide on the drive shaft of the motor 3. A second spring 15 is mounted on the drive shaft of the motor 3. The second spring 15 is pressed between the slide plate 6 and the motor 3 to assist in pre-tightening.

[0032] The working principle of this utility model is as follows: After the power supply to the motor 3 is stopped and the motor 3 has completely stopped rotating, the connection between the lever 11 and the adjustment hole 14 is released by pulling out the pin inserted in the lever 11. Then, the lever 11 is moved so that the lever 11 rotates around the support rod 10 as the center. After the hole of the lever 11 is aligned with another set of adjustment holes 14 on the adjustment plate 13, the pin is inserted into the hole again to complete the movement of the lever 11.

[0033] During the aforementioned process of actuating the lever 11, the connecting block 12, which is rotatably connected to the bottom surface of the lever 11, moves in the same direction as the lever 11. Since the connecting block 12 is hinged, during the movement of the connecting block 12, the sliding plate 6 is driven to slide on the drive shaft of the motor 3 through the sliding groove 60 on the sliding plate 6. The sliding plate 6, through the connecting bolt 9 and the positioning component, drives the drive plate 5 away from the driven plate 4 on the adapter component 2, thereby completing the separation operation.

[0034] When maintenance is required on the slide plate 6 and drive plate 5, first unscrew the connecting bolt 9 on the outer wall of the drive plate 5 from the through hole 50 to initially disconnect the connection between the drive plate 5 and the protrusion 61. Then, the staff will pull the drive plate 5 and the slide plate 6 in opposite directions (or rotate either the drive plate 5 or the slide plate 6) so that the pulling force is greater than the thrust of the first spring 7, causing the positioning pin 8 to leave the positioning hole 62 and be squeezed back into the positioning groove 52, thus disconnecting the positioning connection between the drive plate 5 and the slide plate 6. Then, they can be tested separately.

[0035] When in use, the second spring 15, which is mounted on the drive shaft of motor 3, can assist in the splicing.
