[0018] This utility model provides a lifting tool for an eccentric assembly of a vibrating conveyor, including a reduction mechanism, a winding drum mechanism, a guide drum assembly, a driven drum assembly, a traction rope, a base, and a support. The reduction mechanism includes a sleeve, a worm gear reducer, and a connecting flange.

[0031] This embodiment provides a lifting tool for an eccentric assembly of a vibrating conveyor. When lifting the eccentric assembly, the eccentric assembly can be kept suspended, preventing it from falling due to uncontrolled gravity, thus improving maintenance efficiency and reducing labor intensity and safety risks.

[0032] In this embodiment, the hoisting tool for the eccentric assembly of the vibratory conveyor includes a reduction mechanism 1, a winding drum mechanism 2, a guide drum assembly 3, a driven drum assembly 4, a traction rope 5, a base 6, and a support base. The reduction mechanism 1 includes a sleeve 11, a worm gear reducer 12, and a connecting flange 13. The sleeve 11 is connected to the input end of the worm gear reducer 12. The worm gear reducer 12 is mounted on the connecting flange 13, which is connected to the base 6. The sleeve 11 is used to connect to an external power mechanism to drive the worm gear reducer. The worm gear reducer 12 moves, and the output end of the worm gear reducer 12 is connected to the winding drum mechanism 2 for transmission. The winding drum mechanism 2 is rotatably mounted on the base 6. The guide drum assembly 3 and the driven drum assembly 4 are both rotatably mounted on the support base. The traction rope 5 has a first connecting end 51 and a second connecting end 52. The first connecting end 51 is fixed on the winding drum mechanism 2, and the second connecting end 52 is used to connect to the eccentric assembly 100. The traction rope 5 can be wound sequentially on the guide drum assembly 3 and the driven drum assembly 4. Understandably, with the above setup, when using this lifting tool, it can be placed on the vibratory conveyor transmission frame 200. The operator can hold the input end of the power mechanism worm gear reducer 12 and input power to it. After being transmitted through the worm gear reducer 12, the winding drum 23 can be rotated, and the traction rope 5 transmits the traction force to the eccentric assembly 100, thus lifting the eccentric assembly 100. The guide drum assembly 3 guides the traction rope 5, facilitating its orderly winding within the winding drum mechanism 2. Because the worm gear reducer 12 has a reverse self-locking characteristic, when the power input is cut off, the eccentric assembly 100 can maintain a suspended state at any suspension height, preventing it from falling due to uncontrolled gravity, thus improving work efficiency and reducing labor intensity and safety risks. In this embodiment, the sleeve 11 is connected to the input shaft of the worm gear reducer 12 via a key connection, and the power of the external power mechanism is transmitted to the input end of the worm gear reducer 12 through the sleeve 11. In this embodiment, the portion of the traction rope 5 wound around the guide drum assembly 3 and the driven drum assembly 4 refers to the middle part of the traction rope 5, that is, the portion between the first connecting end 51 and the second connecting end 52 of the traction rope 5 can be wound sequentially around the guide drum assembly 3 and the driven drum assembly 4.

[0033] It should be noted that the external power mechanism refers to a commonly used handheld power mechanism. For example, a pneumatic wrench, an electric wrench, etc., as long as it meets the actual use requirements, this embodiment does not make a specific limitation.

[0034] Furthermore, the winding drum mechanism 2 includes a winding drum shaft 21, a support member 22, a winding drum 23, and a fixing assembly 24. One end of the winding drum shaft 21 is connected to the output end of the worm gear reducer 12. The support member 22 is mounted on the base 6, and the winding drum shaft 21 passes through the support member 22. The winding drum 23 can rotate relative to the support member 22. The winding drum 23 is sleeved and fixed to the winding drum shaft 21, and the fixing assembly 24 can lock the winding drum shaft 21. It is understood that the ability to rotate relative to the support member 22 facilitates the release or retraction of the traction rope 5, thereby adjusting the position of the eccentric assembly 100. Furthermore, the fixing assembly 24 can fix the winding drum shaft 21 when the eccentric assembly 100 is in a suspended state, further ensuring that the winding drum shaft 21 is in a stationary state, thus improving the stability of the entire lifting tool. In this embodiment, the winding drum 23 is connected to the winding drum shaft 21 by a key connection, and the support member 22 is fixed to the base 6 by bolts.

[0035] It should be noted that in this embodiment, two traction ropes 5 are provided. The two traction ropes 5 facilitate the connection between the two sides of the eccentric assembly 100, improving the stability when hoisting the eccentric assembly 100. Of course, in other embodiments, only one traction rope 5 can be provided, and the second connecting end 52 of the traction rope 5 can be connected to the eccentric assembly 100 in conjunction with other connecting structures.

[0036] Furthermore, the winding drum 23 has two winding grooves, the width of which is greater than the diameter of the traction rope 5. Specifically, the two traction ropes 5 are correspondingly arranged with the two winding grooves. It can be understood that by providing two winding grooves, the two traction ropes 5 are located in their respective grooves, facilitating the driving of the two traction ropes 5 and reducing the probability of interference, thus ensuring the smooth operation of the lifting tool.

[0037] For example, the fixing component 24 is located at the other end of the winding drum shaft 21 and is fixed to the base 6. The fixing component 24 has a limiting groove, a first limiting through hole, and a limiting member. The other end of the winding drum shaft 21 is located in the limiting groove, and a second limiting through hole is provided at the other end of the winding drum shaft 21. The limiting member can be located in the first limiting through hole and the second limiting through hole to fix the winding drum shaft 21. Specifically, the first limiting through hole is connected to the limiting groove. By providing corresponding first and second limiting through holes on the fixing component 24 and the winding drum shaft 21, when the eccentric assembly 100 is in a hovering state, the limiting member can be located in the first and second limiting through holes, which facilitates the fixing of the winding drum shaft 21.

[0038] In this embodiment, a plurality of first limiting through holes can be spaced apart on the circumference of the other end of the winding drum shaft 21, and a plurality of second limiting through holes can be spaced apart on the periphery of the limiting groove. The limiting member can be located in any of the first limiting through holes and any of the second limiting grooves to improve the convenience of fixing the winding drum shaft 21. In this embodiment, the limiting member can be a screw.

[0039] Furthermore, the guide drum assembly 3 includes a guide shaft 31, a needle roller bearing 32, and a guide drum 33. The guide shaft 31 is fixed to the support base, and the needle roller bearing 32 is installed between the guide drum 33 and the guide shaft 31. An annular guide groove is provided on the outer periphery of the guide drum 33. It can be understood that by providing the annular guide groove, the movement of the traction rope 5 can be guided, preventing the two traction ropes 5 from contacting and interfering. In this embodiment, the guide shaft 31 and the needle roller bearing 32 are clearance-fitted.

[0040] For example, two annular guide grooves are provided, and the width of the annular guide grooves is greater than the diameter of the traction rope 5. Specifically, two traction ropes 5 are correspondingly provided with two annular guide grooves. It can be understood that the width of the annular guide groove is greater than the diameter of the corresponding traction rope 5, which facilitates the guidance of the traction rope 5, prevents the traction rope 5 from jumping out of the annular guide groove during movement, and ensures the stability of the movement of the traction rope 5. Furthermore, the one-to-one correspondence between the two traction ropes 5 and the two annular guide grooves further reduces the probability of interference between the two traction ropes 5. In this embodiment, the width of the annular guide groove is slightly greater than the diameter of the traction rope 5 to avoid the annular guide groove being too wide, which would be detrimental to the guiding effect of the traction rope 5.

[0041] In this embodiment, the center distance between the two winding annular grooves of the winding drum 23 is the same as the center distance between the two annular guide grooves of the guide drum 33.

[0042] Furthermore, the driven drum assembly 4 includes a driven drum shaft 41, a support bearing 42, and a driven drum 43. The driven drum shaft 41 is fixed to the support base, and the support bearing 42 is installed between the driven drum 43 and the driven drum shaft 41. An annular receiving groove is provided on the driven drum. It can be understood that the use of the support bearing 42 to realize the relative movement between the driven drum 43 and the driven drum shaft 41 improves the stability of the driven drum rotation, and the annular receiving groove on the driven drum facilitates the winding of the traction rope 5. In this embodiment, the driven drum assembly 4 and the guide drum assembly 3 are spaced apart and located at the end away from the base 6 from the drum assembly support base, which facilitates the traction rope 5 to change the traction direction, equivalent to the function of a fixed pulley.

[0043] For example, two annular receiving grooves are provided, and the width of the annular receiving groove is greater than the diameter of the traction rope 5. Specifically, two traction ropes 5 are provided in a one-to-one correspondence with two annular receiving grooves. It can be understood that the width of the annular receiving groove is greater than the diameter of the corresponding traction rope 5, which facilitates the guidance of the traction rope 5, prevents the traction rope 5 from jumping out of the annular receiving groove during movement, and ensures the stability of the movement of the traction rope 5. Furthermore, the one-to-one correspondence between the two traction ropes 5 and the two annular receiving grooves further reduces the probability of interference between the two traction ropes 5. In this embodiment, the inner ring of the support bearing 42 is interference-fitted with the driven drum shaft 41, which improves the stability of the connection between the support bearing 42 and the driven drum shaft 41, and eliminates the need for an additional connection structure.

[0044] Furthermore, the center-to-center distance between the two annular receiving troughs is greater than the center-to-center distance between the two annular guide troughs.

[0045] In this embodiment, the support base includes two parallel support side plates 7, both of which are connected to the base 6. Specifically, both ends of the guide shaft 31 are fixed to the two support side plates 7, and both ends of the driven drum shaft 41 are fixed to the two support side plates 7, facilitating the fixation of the guide shaft 31 and the driven drum shaft 41. In this embodiment, a connecting plate is also connected between the two support side plates 7 to improve the overall stability of the support base.

[0046] In this embodiment, taking the maintenance of the eccentric assembly 100 as an example, the working process of the lifting tool is as follows:

[0047] The lifting tool is placed on the transmission frame 200 of the vibrating conveyor. The operator holds the power mechanism, and the driving force is transmitted through the worm gear reducer 12, which drives the winding drum 23 to rotate. After the traction rope 5 is wound on the winding drum 23, the traction force is transmitted through the traction rope 5 to the eccentric assembly 100, lifting the eccentric assembly 100. When the eccentric assembly 100 reaches the preset suspension height, the power input of the hand-held power mechanism is cut off. The reverse self-locking characteristic of the worm gear reducer 12 keeps the eccentric assembly 100 in a suspended state, making it convenient for operators to perform maintenance.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
