Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an anti-deviating chain fixing device for a carbon black elevator. Background Art

[0002] The tube chain conveyor used for carbon black transportation can effectively solve dust pollution. The tube chain conveyor has a compact structure, occupies a small space, can change the conveying direction in three dimensions, and the dried carbon black particles need to be transported into the finished product silo through an elevator. The elevator is composed of components such as chain, upper sprocket, bottom sprocket, reducer and hopper. In the actual production process of carbon black, the elevator is a key conveying equipment for carbon black production. Whether it can operate normally is related to the stability of the entire carbon black production system.

[0003] During the long-term rotation of the sprocket that drives the chain of the existing carbon black elevator, the sprocket often deviates from the center, which causes the chain and the hopper connected to the chain to shift, and the stability of the driving sprocket and the chain cannot be fully guaranteed; at the same time, the current carbon black elevator often directly drives the driving sprocket to rotate the chain through the driving device, but the weight of the driving sprocket itself is limited, so the rotational inertia of the sprocket is also very limited, so a driving device with greater power is required to meet the material transportation needs of the carbon black elevator.

[0004] Therefore, it is urgent to provide a carbon black elevator anti-drift chain fixing device to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the shortcomings of the above-mentioned prior art and provide an anti-drift chain fixing device for a carbon black elevator.

[0006] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a carbon black elevator anti-deviation chain fixing device, including an elevator shell as a mounting carrier, a lifting mechanism is arranged inside the elevator shell, and chain fixing mechanisms are arranged at both ends of the lifting mechanism, and counterweight mechanisms are arranged at both ends of the chain fixing mechanism. Circular through holes are symmetrically opened at the bottom of the two ends of the elevator shell, and an outer shell is installed on the outside of the circular through hole through a first connecting member. A limiting bearing is installed at the middle position of the inner wall of the outer shell, and a connecting bearing is installed at the center position of the inner shell away from one end of the elevator shell. When the driving shaft drives the disc bin to rotate, the outer side of the disc bin is close to the inner ring of the limiting bearing, and the two ends of the driving shaft are respectively located at the inner rings of the two sets of connecting bearings, thereby improving the rotation stability of the driving shaft and the disc bin.

[0007] The utility model is further configured as follows: the lifting mechanism includes a drive shaft, the drive shaft is located at the bottom end inside the elevator shell, a drive sprocket is installed at the middle position of the outer side of the drive shaft, an elevator chain is provided on the outer side of the drive sprocket, and hoppers are evenly installed on the elevator chain.

[0008] Through the above technical solution, when the external drive device drives the drive shaft to rotate, the drive shaft drives the elevator chain to rotate through the drive sprocket, and then drives the hopper on the elevator chain, so that the hopper can continuously transport the material.

[0009] The utility model is further configured as follows: the chain fixing mechanism includes a U-shaped frame and a fixed plate, the U-shaped frame and the fixed plate are respectively located at the two ends of the driving sprocket, the U-shaped frame and the fixed plate are fixedly connected by a second connecting piece, the two ends of the driving shaft respectively pass through the middle position of the U-shaped frame and the fixed plate, and slewing bearings are symmetrically installed at the middle position of the inner and outer sides of the U-shaped frame and the fixed plate, and the driving shaft passes through the inner rings of four sets of slewing bearings.

[0010] Through the above technical solution, the U-shaped frame and the fixed plate are fixedly connected using a second connecting member, so that the inner rings of the two sets of turntable bearings on the inner sides of the U-shaped frame and the fixed plate are against both sides of the drive sprocket, thereby preventing the drive sprocket from moving or offsetting on the drive shaft.

[0011] The present invention is further configured as follows: the counterweight mechanism includes a disc bin, which is provided with two groups, and the two groups of disc bins are respectively sleeved on the two ends of the outer side of the driving shaft, a sleeve sleeved on the outer side of the driving shaft is installed at the middle position inside the disc bin, and six groups of sliding rods fixedly connected to the inner wall of the disc bin are evenly installed on the outer side of the sleeve, and the outer side of the sliding rod is respectively sleeved with a counterweight block and a return spring, and the end of the return spring away from the counterweight block is fixedly connected to the inner wall of the disc bin, a fixing ring is installed on the outer end of the sliding rod close to the sleeve, and the two ends of the outer side of the driving shaft are symmetrically threaded with fixing nuts that cooperate with the sleeve.

[0012] Through the above technical solution, after the slewing bearing puts the disc bin on the drive shaft, the sleeve is also put on the outside of the drive shaft. Since one side of the disc bin is in close contact with the inner ring of an adjacent set of slewing bearings, the sleeve can be fixed together with the disc bin on the drive shaft by tightening the fixing nut, so that the drive shaft can drive the disc bin to rotate stably.

[0013] The utility model is further configured as follows: the first connecting member includes a fixed flange, which is installed on the outside of the outer shell close to one end of the elevator shell, and six groups of first threaded columns compatible with the fixed flange are evenly installed at the bottom of both ends of the elevator shell close to the circular through holes, and the outer threads of the first threaded columns are provided with connecting nuts.

DETAILED DESCRIPTION

[0032] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0033] See also Figure 1 - Figure 7, a carbon black elevator anti-deviation chain fixing device includes an elevator shell 10 as an installation carrier, a lifting mechanism 20 is arranged inside the elevator shell 10, and chain fixing mechanisms 30 are arranged at both ends of the lifting mechanism 20, and counterweight mechanisms 40 are arranged at both ends of the chain fixing mechanism 30. Circular through holes 11 are symmetrically opened at the bottom of both ends of the elevator shell 10, and an outer shell 12 is installed on the outside of the circular through hole 11 through a first connecting member 13. A limited bearing 14 is installed at the middle position of the inner wall of the outer shell 12, and a connecting bearing 15 is installed at the center position of the outer shell 12 away from one end of the elevator shell 10. When the external driving device drives the driving shaft 21 to rotate, the driving shaft 21 drives the elevator chain 23 to rotate through the driving sprocket 22, and then drives the hopper 24 on the elevator chain 23, so that the hopper 24 can continuously transport the material.

[0034] like Figure 3 - Figure 5 and Figure 7 As shown, the chain fixing mechanism 30 includes a U-shaped frame 31 and a fixing plate 32. The U-shaped frame 31 and the fixing plate 32 are respectively located at the two ends of the driving sprocket 22. The U-shaped frame 31 and the fixing plate 32 are fixedly connected by a second connecting member 36. The two ends of the driving shaft 21 pass through the middle position of the U-shaped frame 31 and the fixing plate 32 respectively. The slewing bearings 35 are symmetrically installed at the middle position of the inner and outer sides of the U-shaped frame 31 and the fixing plate 32. The driving shaft 21 passes through the inner rings of the four groups of slewing bearings 35. The second connecting member 36 includes a second threaded column 361. The second threaded column 361 is provided in four groups, and the four groups of second threaded columns 361 are located On both sides of the U-shaped frame 31 near one end of the fixed plate 32, the outer threads of the second threaded column 361 are provided with butterfly nuts 362. After the U-shaped frame 31 and the fixed plate 32 are respectively put on the two ends of the outer side of the drive shaft 21, the fixed plate 32 is connected to one end of the U-shaped frame 31, and then the butterfly nuts 362 on the second threaded column 361 are tightened to fix the fixed plate 32 and the U-shaped frame 31 together, so that the inner rings of the two sets of turntable bearings 35 on the inner sides of the U-shaped frame 31 and the fixed plate 32 are against the two sides of the drive sprocket 22, thereby preventing the drive sprocket 22 from moving or offsetting on the drive shaft 21.

[0035] like Figure 5 - Figure 7As shown, the counterweight mechanism 40 includes a disc bin 41, which is provided with two groups, and the two groups of disc bins 41 are respectively sleeved on the two ends of the outer side of the drive shaft 21, and a sleeve 42 sleeved on the outer side of the drive shaft 21 is installed at the middle position inside the disc bin 41. Six groups of slide bars 43 fixedly connected to the inner wall of the disc bin 41 are evenly installed on the outer side of the sleeve 42. The outer side of the slide bar 43 is respectively sleeved with a counterweight block 44 and a return spring 45, and the end of the return spring 45 away from the counterweight block 44 is fixedly connected to the inner wall of the disc bin 41, and a fixing ring 46 is installed on the outer side of the slide bar 43 near the sleeve 42. The two ends of the outer side of the drive shaft 21 are symmetrically threaded with fixing nuts 47 that cooperate with the sleeve 42. The end of the sleeve 42 away from the drive sprocket 22 is provided with a rubber ring sleeved on the outer side of the drive shaft 21, and the rubber ring is located between the sleeve 42 and the fixing nut 47. After the bearing 35 has sleeved the disc bin 41 on the drive shaft 21, the sleeve 42 is also sleeved on the outside of the drive shaft 21. Since one side of the disc bin 41 is in close contact with the inner ring of an adjacent set of slewing bearings 35, the sleeve 42 can be fixed to the drive shaft 21 together with the disc bin 41 by tightening the fixing nut 47, so that the drive shaft 21 can drive the disc bin 41 to rotate stably together. After the disc bin 41 is fixed to the drive shaft 21 using the fixing nut 47 and the sleeve 42, the rubber ring can improve the fixing effect of the fixing nut 47 and the slewing bearing 35 on the sleeve 42. When the drive shaft 21 drives the disc bin 41 to rotate, the two groups of disc bins 41 can drive the inner rings of the two groups of slewing bearings 35 located on the outside of the U-shaped frame 31 and the fixed plate 32 to rotate, thereby further improving the stability of the drive shaft 21 driving the disc bin 41 to rotate.

[0036] When the present invention is in use, when the external drive device drives the drive shaft 21 to rotate gradually, the drive shaft 21 drives the disc bin 41 to rotate gradually through the sleeve 42 and the fixing nut 47, and the centrifugal force on the counterweight 44 gradually increases, the counterweight 44 gradually slides on the slide rod 43, the return spring 45 is shortened under the force, and the drive shaft 21 drives the elevator chain 23 to rotate through the drive sprocket 22, and the drive sprocket 22 drives the inner rings of the two sets of turntable bearings 35 located on the inner sides of the U-shaped frame 31 and the fixed plate 32 to rotate. When the drive shaft 21 gradually stops rotating, the counterweight 44 gradually slides on the slide rod 43 toward one end of the sleeve 42, and the return spring 45 gradually restores its original length.

[0037] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
