Description

Technical Field

[0001] The utility model relates to the technical field of roller brush transmission, in particular to a flange shaft connection device and a dust removal roller brush device. Background Art

[0002] Electromagnetic ultrasonic flaw detection is a very superior method for inspecting the quality of steel plates, but it also has limitations. Under the action of strong magnetism, it can not only provide an amplified signal but also cause iron filings in the environment to be adsorbed to the sensor, resulting in the failure of the mechanical performance of the sensor. Therefore, the dust removal roller brush device came into being. Although the dust removal roller brush has a good effect, as a consumable, the replacement frequency is relatively high, and the disassembly and assembly are not easy. It not only wastes working hours but also increases the difficulty for the operators.

[0003] Generally, the roller brush shaft is made as a whole and is fixed on the bearings at both sides for rotation. However, under the current working conditions, the roller brush needs to be replaced frequently.

[0004] As a consumable, the refurbishment process for the roller brush is to replace the brush on the roller brush and retain the original roller body. Due to long-term high-intensity operation, the roller body will also be damaged to varying degrees, resulting in an increase in cost.

[0005] The Chinese utility model patent with the publication number CN202416226U discloses a roller brush shaft transmission device for a road sweeper. It realizes the connection between the motor shaft and the roller brush shaft through assembly, making the disassembly and assembly of the roller brush convenient and avoiding the defects of insufficient stability of welded fixation and complex assembly. However, this patent does not protect the connection flange. After long-term use, a gap will be generated between the flange plate I and the flange plate II, resulting in the loosening of the connection between the motor shaft and the roller brush shaft, thus causing abnormal noise or stopping rotation. Since this patent does not protect the connection flange, it is also easy to cause damage to the flange plate I and the flange plate II. Summary of the Utility Model

[0037] It should also be understood that the terms used in the specification of the embodiments of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present utility model. As used in the specification of the embodiments of the present utility model and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are intended to include the plural forms.

[0038] Refer to Figures 1-6, an embodiment of the present utility model provides a flange shaft connection device, which is used to connect the brush roller to the power system, and has the advantages of convenient disassembly and assembly and the ability to protect the brush roller body. The flange shaft connection device includes a spigot block 30, a drive shaft 10, a roller shaft, a first flange 40 provided at one end of the drive shaft 10, and a second flange 50 provided at one end of the roller shaft (the roller shaft is provided in the middle of the roller). The specific structure is introduced as follows:

[0039] The drive shaft 10 is used to connect to the power system, such as a motor, which is not specifically limited in the present utility model. The roller shaft refers to the shaft of the roller 20 of the brush roller, and the power system drives the roller shaft to rotate through the drive shaft 10, so as to make the brush roller rotate.

[0040] The first flange 40 is provided at one end of the drive shaft 10 and is fixedly connected to one end of the drive shaft 10, for example, it can be connected by fasteners, which is not specifically limited in the present utility model. Two protruding and spaced transmission blocks 41 are provided on the end face of the first flange 40, and a first fitting groove 42 is formed between the two transmission blocks 41. The first fitting groove 42 is used to inlay a part of the spigot block 30. The second flange 50 is provided at one end of the roller shaft, and the second flange 50 is fixedly connected to one end of the roller shaft, for example, it can be connected by fasteners, which is not specifically limited in the present utility model.

[0041] The second flange 50 is provided with a second fitting groove 51, and the second fitting groove 51 includes a first groove section 511 and a second groove section 512. The first groove section 511 and the second groove section 512 are communicated with each other.

[0042] The two transmission blocks 41 of the first flange 40 are embedded in the first groove section 511, and the second groove section 512 is communicated with the first fitting groove 42, that is, the second groove section 512 and the first fitting groove 42 are communicated in space.

[0043] The spigot block 30 is detachably embedded in the second groove section 512 and the first fitting groove 42. Specifically, a part of the spigot block 30 is embedded in the first fitting groove 42, and another part of the spigot block 30 is embedded in the second groove section 512.

[0044] When the drive shaft 10 rotates, the power is transmitted to the roller shaft through the spigot block 30. In the present utility model, the hardness of the spigot block 30 is less than the hardness of the first flange 40 and the second flange 50. Therefore, while the spigot block 30 plays a transmission role, it can also serve as a vulnerable part to protect the first flange 40 and the second flange 50, and avoid damage to the brush roller body. After the spigot block 30 is damaged, directly replace the spigot block 30, which is convenient, fast, and has a lower cost.

[0045] The flange-shaft connection device proposed in the embodiment of the utility model comprises a stop block 30, a transmission shaft 10, a roller shaft, a first flange 40 arranged at one end of the transmission shaft 10, and a second flange 50 arranged at one end of the roller shaft; the end surface of the first flange 40 is provided with two protruding and spaced transmission blocks 41, and a first fitting groove 42 is formed between the two transmission blocks 41; the second flange 50 is provided with a second fitting groove 51, and the second fitting groove 51 includes a first groove section 511 and a second groove section 512; the two transmission blocks 41 of the first flange 40 are embedded in the first groove section 511, so that the second groove section 512 and the first fitting groove are engaged with each other. 42 is connected; the stop block 30 is detachably embedded in the second groove section 512 and the first engaging groove 42, wherein the hardness of the stop block 30 is less than the hardness of the first flange 40 and the second flange 50. It can be seen that, on the one hand, the components of the flange-shaft connecting device realize transmission connection through the engaging relationship, and disassembly and assembly are convenient; on the other hand, the hardness of the stop block 30 is less than the hardness of the first flange 40 and the second flange 50, so that the stop block 30 can not only play a transmission role, but also serve as a wearing part to protect the first flange 40 and the second flange 50, thereby avoiding damage to the roller brush body.

[0046] Furthermore, in some embodiments, such as the present embodiment, the number of the second slot sections 512 is two, and the two second slot sections 512 are respectively arranged on both sides of the first slot section 511, that is, the first slot section 511 is located in the middle, and the two second slot sections 512 are respectively located on both sides of the first slot section 511.

[0047] The number of the stopper blocks 30 is two; the two stopper blocks 30 are correspondingly embedded in the two second groove sections 512, and are both embedded in the first engaging groove 42. For example, see Figure 6 A portion of the stopper block 30 located at the upper side is embedded in the second groove section 512 located at the upper side, and the other portion is embedded in the first fitting groove 42; a portion of the stopper block 30 located at the lower side is embedded in the second groove section 512 located at the lower side, and the other portion is embedded in the first fitting groove 42. The two symmetrically arranged stopper blocks 30 can effectively improve the stability of the transmission.

[0048] Further, the spigot block 30 includes a first fitting block 31 and a second fitting block 32, and the second fitting block 32 is disposed on one side of the first fitting block 31; wherein, the first fitting block 31 is fitted into the second groove section 512, and the second fitting block 32 is disposed in the first fitting groove 42. The width of the first fitting block 31 is greater than the width of the second fitting block 32 and the width of the first fitting groove 42. Thus, the first fitting block 31 cannot be embedded into the first fitting groove 42, and a limit is formed between the first fitting block 31 and the transmission block 41.

[0049] Specifically, the second fitting block 32 is vertically disposed in the middle of one side of the first fitting block 31, so that the overall shape of the spigot block 30 is T-shaped. Thus, the spigot block 30 itself is an axisymmetric structure, which can effectively improve the stability of transmission.

[0050] Further, the first fitting block 31 and the transmission block 41 are detachably connected. For example, the detachable connection is achieved through fasteners. By detachably connecting the first fitting block 31 and the transmission block 41, on the one hand, the connection stability is improved, and on the other hand, it is convenient for disassembly.

[0051] Specifically, a first fastening hole (the first fastening hole is occupied by the first fastener 60) is provided on the first fitting block 31, and a second fastening hole 411 is provided on the transmission block 41. The first fastener 60 sequentially passes through the first fastening hole and the second fastening hole 411 to detachably connect the first fitting block 31 and the transmission block 41.

[0052] The first fastening hole and the second fastening hole 411 may specifically be screw holes, and the first fastener 60 may specifically be a screw or a bolt, which is not specifically limited in the present utility model.

[0053] The number of the first fastening holes may be two, and the two first fastening holes are located on both sides of the first fitting block 31. Each of the two transmission blocks 41 is provided with a second fastening hole 411. Thus, it can be realized that both sides of the first fitting block 31 are detachably fixed on the two transmission blocks 41 respectively.

[0054] Further, the first flange 40 and the second flange 50 are detachably connected. By detachably connecting the first flange 40 and the second flange 50, on the one hand, the connection stability is improved, and on the other hand, it is convenient for disassembly.

[0055] Specifically, a third fastening hole (occupied by a second fastener 70) is provided on the first flange 40, and a fourth fastening hole 52 is provided on the second flange 50. The second fastener 70 passes through the third fastening hole and the fourth fastening hole 52 in sequence to detachably connect the first flange 40 and the second flange 50. The second fastener 70 can specifically be a screw or a bolt, which is not specifically limited in the present utility model.

[0056] The number of the third fastening holes is the same as that of the fourth fastening holes 52 and they correspond to each other one by one, thereby improving the connection stability and reliability.

[0057] Furthermore, the spigot block 30 is in clearance fit with the second groove section 512 and the first fitting groove 42. Specifically, there is a gap between the first fitting block 31 of the spigot block 30 and the second groove section 512; there is a gap between the second fitting block 32 of the spigot block 30 and the first fitting groove 42. The advantage of having a gap is that: in the case of instantaneous rotation or reverse rotation, if there is no gap, it is a rigid connection, and the instantaneous torque will cause damage to the first flange 40 and the second flange 50. In the case of having a gap, it can play a certain buffering role, thereby protecting the first flange 40 and the second flange 50 well.
