Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a downward-turning guiding structure of an elevator. Background Technique

[0002] An elevator is a mechanical device that uses hoppers fixed to a traction chain or a belt to transport materials upward in a vertical or nearly vertical direction. For example, a tubular bucket elevator disclosed in the utility model patent with the Chinese patent number CN201921106075.2 uses a motor to drive a chain to provide power for lifting the hopper. When the hopper moves to the turning gear disk at the end of the discharging section, the turning guide block moves along the arc surface of the hopper top ring on the turning gear disk, so that the hopper turns over and the materials in the hopper are poured out. The poured materials fall out from the discharging guide groove to achieve the purpose of lifting materials. However, the turning guide block and the arc surface of the hopper top ring are in frictional guiding cooperation. During friction, not only noise and abnormal noise are caused, but also wear occurs, which not only affects the service life, but also vibration occurs, resulting in the scattering of materials in the hopper and affecting the material conveying effect. Therefore, it is necessary to further improve. Content of the Utility Model

[0003] The utility model aims to provide a downward-turning guiding structure of an elevator to overcome the deficiencies in the prior art.

[0004] A downward-turning guiding structure of an elevator designed according to this purpose includes an elevator body, a driving chain, and a driver. The driving chain rotates along the track of the elevator body and is evenly and drivingly connected with a plurality of bowl plate groups. The driver is fixedly arranged on the elevator body and is drivingly connected with the driving chain. An upper guiding member is fixedly arranged at the discharging end of the elevator body. A rotating wheel that is in rolling cooperation with the upper guiding member is rotatably arranged on the bowl plate group. The bowl plate group is guided to turn downward at the discharging end of the elevator body through the cooperation of the rotating wheel and the upper guiding member.

[0005] An arc-shaped groove is arranged on the upper guiding member. The rotating wheel is rotatably arranged on the side of the bowl plate group and rolls along the track of the arc-shaped groove when the bowl plate group moves to the discharging end of the elevator body.

[0006] An upper guiding flange is arranged on the upper guiding member corresponding to the arc-shaped groove. The rotating wheel is guided to roll into and / or out of the arc-shaped groove through the upper guiding flange.

[0007] A chain guide rail is provided on the lifting body. The chain guide rail has two sections, and the two sections of the chain guide rail are fixedly arranged at intervals along the track of the lifting body. A top drive gear and a bottom drive gear are respectively rotatably arranged at the discharging end and the feeding end of the lifting body. The top drive gear is located in front of the two sections of the chain guide rail, and the bottom drive gear is located behind the two sections of the chain guide rail. The driver is drivingly connected to the top drive gear or the bottom drive gear. The drive chain meshes with the top drive gear and the bottom drive gear and is guided to rotate along the track of the two sections of the chain guide rail.

[0008] The upper guide is located in front of the two sections of the chain guide rail, and the inlet and outlet of the arc-shaped groove respectively correspond to the two sections of the chain guide rail.

[0009] The lifting body is respectively provided with a top transmission shaft and a bottom transmission shaft corresponding to the top drive gear and the bottom drive gear. The top drive gear and the bottom drive gear are respectively connected to the top transmission shaft and the bottom transmission shaft in a matching manner. The driver is fixedly arranged at the discharging end of the lifting body and is drivingly connected to the top transmission shaft.

[0010] The bowl set includes a bowl base and a bowl disassembled and assembled on the bowl base. The rotating wheel is rotatably arranged on the side of the bowl base. A chain connecting shaft also extends from the side of the bowl base and is drivingly connected to the drive chain through the chain connecting shaft.

[0011] A lifting guide rail is provided on the lifting body. The lifting guide rail is fixedly arranged along the track of the lifting body. A lifting rotating wheel is rotatably arranged on the bowl base and rolls along the track of the lifting guide rail through the lifting rotating wheel.

[0012] The lifting guide rail is provided with a lower turning-out flanging corresponding to the downward turning of the bowl set. When the bowl set moves to the discharging end of the lifting body, the lifting rotating wheel rolls onto the lower turning-out flanging and turns downward to leave the lifting guide rail.

[0013] A bowl clamping plate, a clamping block, a clamping block rotating shaft, and a clamping lock releasing member are arranged on the bowl base. The bowl clamping plate is fixedly arranged on the bowl base, and a clamping interface is formed between the two. One end of the clamping block is connected to the clamping block rotating shaft in a matching manner and is rotatably arranged on the bowl base through the clamping block rotating shaft. The bowl is clamped or disassembled from the clamping interface by the rotation of the clamping block. The other end of the clamping block is provided with a clamping portion. The clamping lock releasing member is rotatably arranged on the bowl base and is locked or separated from the clamping portion when rotating. A rotating acting member is also arranged at the end of the clamping lock releasing member.

[0014] Through the improvement of the above structure, the utility model drives the driving chain to rotate by means of a driver, and then drives a plurality of bowl groups to move on the lifting body. When the bowl group moves to the discharging end on the lifting body, it rolls on the upper guide member through the rotating wheel and is guided to turn down at the discharging end on the lifting body. The bowl group pours out the material when it is guided to turn down, so as to achieve the purpose of lifting and conveying the material.

[0015] Due to the rolling action of the rotating wheel on the upper guide member, problems such as noise, abnormal noise, vibration, and short service life caused by the friction and turning down of the bowl group can be avoided. Therefore, the turning-down stability and service life of the bowl group are improved, ensuring that the material can be stably lifted and conveyed. Moreover, the rolling and guiding turning-down process of the bowl group is smooth, without jamming, and only a small-power driver is required to complete the driving, which is energy-saving, environmentally friendly, and has low production costs.

Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0031] The present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0032] Refer to Figures 1-14 , the guiding and downward-turning structure of this elevator includes an elevator body 100, a driving chain, and a driver 10. The driving chain rotates along the track of the elevator body 100 and is evenly and drivingly connected with a plurality of bowl and plate sets C. The driver 10 is fixedly arranged on the elevator body 100 and is drivingly connected with the driving chain. An upper guiding member 11 is fixedly arranged at the discharging end of the elevator body 100. A rotating wheel C11 that is in rolling cooperation with the upper guiding member 11 is rotatably arranged on the bowl and plate set C. The bowl and plate set C is guided and turned downward at the discharging end of the elevator body 100 through the cooperation of the rotating wheel C11 and the upper guiding member 11.

[0033] In this embodiment, the driver 10 drives the driving chain to rotate, thereby driving a plurality of bowl and plate sets C to move on the elevator body 100. When the bowl and plate set C moves to the discharging end of the elevator body 100, it rolls on the upper guiding member 11 through the rotating rotating wheel C11 and is guided and turned downward at the discharging end of the elevator body 100. The bowl and plate set C pours out the material when it is guided and turned downward, so as to achieve the purpose of lifting and conveying the material.

[0034] Since the rotating wheel C11 rolls on the upper guide member 11, it can avoid noise, abnormal sound, vibration, and short service life caused by the bowl and plate group C turning down due to friction, thereby improving the turning-down stability and service life of the bowl and plate group C, ensuring that the material can be stably lifted and transported, and the rolling guide turning-down process of the bowl and plate group C is stable and smooth without any jamming, and only a small-power driver 10 is needed to complete the driving, which is energy-saving and environmentally friendly, and has low production costs.

[0035] An arc groove 13 is provided on the upper guide member 11 , and the rotating wheel C11 is rotatably provided on the side of the bowl assembly C and rolls along the track of the arc groove 13 when the bowl assembly C moves to the unloading end of the lifting body 100 .

[0036] The provision of the arc groove 13 is not only conducive to the rolling limit of the rotating wheel C11, but also can prevent the bowl and plate set C from swinging or shaking when turning down.

[0037] The upper guide member 11 is provided with an upper guide flange 14 corresponding to the arc groove 13 , and the rotating wheel C11 is guided by the upper guide flange 14 to roll into and / or exit the arc groove 13 .

[0038] A chain guide 15 is provided on the lifting body 100. The chain guide 15 is provided with two sections. The two sections of the chain guide 15 are fixedly arranged at intervals along the trajectory of the lifting body 100. The upper unloading end and the lower feeding end of the lifting body 100 are respectively rotatably provided with a top transmission gear 16 and a bottom transmission gear. The top transmission gear 16 is located in front of the two sections of the chain guide 15, and the bottom transmission gear is located behind the two sections of the chain guide 15. The driver 10 is drivingly connected with the top transmission gear 16 or the bottom transmission gear, and the driving chain is meshed with the top transmission gear 16 and the bottom transmission gear, and is guided to rotate along the trajectory of the two sections of the chain guide 15.

[0039] In this embodiment, the lifting body 100 is Z-shaped as a whole, and its corners are arc-shaped transitions. Support feet of different heights are respectively arranged at the front and rear positions of the lifting body 100. The lifting body 100 is formed by multiple sheet metal parts spliced in a left-right symmetrical manner. Two sections of chain guides 15 are respectively arranged on the left and right sheet metal parts. The shape of the chain guides 15 is the same as that of the lifting body 100. At the same time, upper guide parts 11 are arranged on the left and right sheet metal parts. Rotating wheels C11 are rotatably arranged on the left and right sides of the bowl and plate group C, so that the left and right sides of the bowl and plate group C can stably realize the movement and guide the downward turning.

[0040] The upper guide member 11 is located in front of the two chain guide rails 15 , and the entrance and exit of the arc-shaped slot 13 correspond to the two chain guide rails 15 .

[0041] In this embodiment, the upper guiding flanging 14 is arranged on the upper side of the upper guiding member 11 and in front of the inlet of the arc-shaped groove 13. The inlet of the arc-shaped groove 13 faces the upper section of the chain guide rail 15, so as to facilitate the guiding and rolling of the rotating wheel C11 into the arc-shaped groove 13. The outlet of the arc-shaped groove 13 corresponds to the lower section of the chain guide rail 15, so as to facilitate the rolling of the rotating wheel C11 out of the arc-shaped groove 13.

[0042] The lifting body 100 is respectively provided with a top transmission shaft 17 and a bottom transmission shaft corresponding to the top transmission gear 16 and the bottom transmission gear. The top transmission gear 16 and the bottom transmission gear are respectively connected and matched with the top transmission shaft 17 and the bottom transmission shaft.

[0043] In this embodiment, the top transmission gear 16 is fixedly connected to the top transmission shaft 17, and the bottom transmission gear is rotatably connected or fixedly connected to the bottom transmission shaft. The lifting body 100 is respectively provided with bearing seats corresponding to the top transmission shaft 17 and the bottom transmission shaft, so that the top transmission shaft 17 and the bottom transmission shaft can respectively rotate on the lifting body 100.

[0044] The driver 10 is fixedly arranged at the discharging end of the lifting body 100 and is drivingly connected to the top transmission shaft 17.

[0045] When the driver 10 works, it drives the top transmission shaft 17 to rotate. When the top transmission shaft 17 rotates, it drives the top transmission gear 16 to rotate, thereby driving the driving chain to rotate on the two sections of the chain guide rail 15 and driving the bottom transmission gear to rotate together through the rotation of the driving chain.

[0046] The bowl set C includes a bowl base C1 and a bowl C2 disassembled and assembled on the bowl base C1. The rotating wheel C11 is rotatably arranged on the side of the bowl base C1. A chain connecting shaft C3 also extends on the side of the bowl base C1 and is drivingly connected to the driving chain through the chain connecting shaft C3.

[0047] A lifting guide rail 18 is arranged on the lifting body 100. The lifting guide rail 18 is fixedly arranged along the track of the lifting body 100. A lifting rotating wheel C4 is rotatably arranged on the bowl base C1 and rolls along the track of the lifting guide rail 18.

[0048] In this embodiment, the lifting guide rail 18 is arranged in one and is located between the chain guide rails 15 that are symmetric left and right. The shape of the lifting guide rail 18 is the same as that of the chain guide rail 15. There is one lifting rotating wheel C4, which rotates at the bottom of the bowl base C1 and is located between the rotating wheels C11 on the left and right sides.

[0049] The lifting guide rail 18 is provided with a downward-turning separation flange 19 corresponding to the dish set C. When the dish set C moves to the discharging end on the lifting body 100, the lifting runner C4 rolls onto the downward-turning separation flange 19 and turns downward away from the lifting guide rail 18. Thus, the lifting runner C4 can smoothly turn downward away from the lifting guide rail 18 while being guided to turn downward.

[0050] The dish base C1 is provided with a dish clamping plate C5, a clamping block C6, a clamping block rotating shaft C7, and a clamping lock separating member C8. The dish clamping plate C5 is fixedly arranged on the dish base C1, and a clamping interface is formed between the two. One end of the clamping block C6 is connected with the clamping block rotating shaft C7 and is rotatably arranged on the dish base C1 through the clamping block rotating shaft C7. The dish C2 is clamped or detached from the clamping interface by the rotation of the clamping block C6. The other end of the clamping block C6 is provided with a locking portion C9. The clamping lock separating member C8 is rotatably arranged on the dish base C1 and is locked or separated from the locking portion C9 when rotating. A rotating acting member C10 is further arranged at the end of the clamping lock separating member C8.

[0051] In this embodiment, the axis of rotation of the clamping lock separating member C8 is perpendicular to the axis of rotation of the clamping block C6.

[0052] When the dish C2 needs to be removed, the user can manually or use a tool to act on the rotating acting member C10, so that the clamping lock separating member C8 rotates on the dish base C1 in a direction away from the locking portion C9. At this time, the clamping lock separating member C8 leaves the locking portion C9, and the clamping block C6 can rotate on the dish base C1 in a direction away from the dish C2 through the clamping block rotating shaft C7, and the dish C2 can be detached from the clamping interface.

[0053] When the dish C2 needs to be assembled, place the dish C2 on the clamping interface, and then drive the clamping block C6 to rotate on the dish base C1 in a direction towards the dish C2 through the clamping block rotating shaft C7, so that the clamping block C6 positions and clamps the dish C2 in the clamping interface. Subsequently, manually or use a tool to act on the rotating acting member C10, so that the clamping lock separating member C8 rotates on the dish base C1 in a direction towards the locking portion C9. At this time, the clamping lock separating member C8 is locked on the locking portion C9, and the assembly of the dish C2 can be completed.

[0054] The arrangement of the rotating acting member C10 is not only used for manual or tool action, but also can press the clamping block C6 to prevent the rotation and retraction of the clamping block C6 and improve the assembly stability of the dish C2.
