Description

Technical Field

[0001] The utility model relates to the technical field of grain dryer lifting equipment, in particular to a bearing seat protection bracket for a lifting seat base. Background Art

[0002] In the operation system of the grain dryer, the lifting seat base plays a core role in supporting the weight of the entire lifting mechanism and bearing dynamic loads. Among them, the base bearing is the key connecting element between the rotating shaft and the lifting seat base. Its stability and durability are directly related to the overall performance and life of the elevator. However, under long-term exposure to high-intensity working environment and external environmental erosion, the rotating shaft on the base bearing is at risk of deformation, wear and even damage, which in turn has an adverse effect on the stable operation and production efficiency of the grain dryer.

[0003] In view of the above problems, the current strategy generally adopted in the technical field is to add a protective bracket outside the base bearing to enhance its protective effectiveness. Unfortunately, most existing protective bracket designs focus mainly on physical protection, while ignoring the integration of intelligent monitoring methods. In particular, they lack sensor components that can monitor the operating status of the bearing in real time, resulting in the inability to promptly warn and take measures when the shaft stops rotating due to deformation, wear or even damage, which may cause grain accumulation, blockage and even more serious mechanical failures and economic losses. To this end, we provide a bearing seat protective bracket for the lifting seat base to solve the above problems. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts a bearing seat protection bracket for a lifting seat base, including a lifting seat base, a base bearing, a connecting piece and an infrared sensor alarm; wherein:

[0010] The above structure enables the rotating shaft to drive the circular part and the part to be detected to rotate together when it rotates, which provides the necessary conditions for the detection of the infrared sensor alarm. By detecting whether the part to be detected passes through the infrared sensor surface regularly, the working status of the rotating shaft on the above-mentioned base bearing is confirmed, and timely warning is given so that the operator can take timely measures to prevent the fault from expanding.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] Please refer to the instruction manual Figure 1-4 The utility model provides a first embodiment of a bearing seat protection bracket for a lifting seat base. In this embodiment, the protection bracket integrates a lifting seat base 1, a base bearing 2, a customized connection component and an infrared sensor monitoring unit. The specific structure and function are described as follows:

[0032] Lifting seat base 1: This component serves as the installation basis of the hoist 5 and is firmly installed on the hoist 5 structure to provide a stable support platform for the entire protective support system.

[0033] The bearing base is integrated with a base bearing 2 on one side of the lifting base, a rotating shaft 6 is passed through the inside of the base bearing 2, one end of the rotating shaft 6 extends deep into the inside of the lifting seat base 1 and is connected to the sprocket 61, and the other end is connected to a circular member 7, a to-be-detected member 71 is fixed on the outer circumferential surface of the circular member 7, the to-be-detected member 71 is an arc-shaped plate-like element in this embodiment, and the to-be-detected member 71 is concentrically matched with the above-mentioned circular member 7, in addition, the surrounding edges of the base bearing 2 are equipped with mounting members 21, and the above-mentioned mounting member 21 is preset with a first through hole 23 for the fixing bolt 22 to pass through and fix.

[0034] The connecting member 3 is designed to be divided into two parts, namely a first connecting part 31 arranged parallel to the mounting member 21 and a second connecting part 32 installed perpendicularly to the first connecting part 31. The first connecting part 31 is provided with a second through hole 311 matching the first through hole 23 on the mounting member 21. The fixing bolts 22 pass through the two groups of through holes in sequence to achieve a fastened connection between the connecting member 3 and the mounting member 21.

[0035] An infrared sensor alarm 4 is fixedly installed on the second connecting part 32 of the connecting piece 3. The infrared detection surface of the infrared sensor alarm 4 is precisely arranged on the rotation trajectory of the part to be detected 71 to ensure that the periodic passage of the part to be detected 71 can be accurately sensed when the rotating shaft 6 rotates, thereby realizing effective monitoring of the working state of the rotating shaft 6 on the base bearing 2. Once an abnormal phenomenon occurs, such as speed change, stalling, etc., the monitoring system can issue an early warning in time, prompting the operator to intervene quickly to avoid fault escalation.

[0036] Further optimization design of the above scheme:

[0037] Removable infrared sensor alarm 4: In order to realize convenient installation, maintenance and replacement of the infrared sensor alarm 4, a connecting hole 321 is opened on the second connecting part 32, and the connecting hole 321 allows the infrared sensor alarm 4 to penetrate. The outer surface of the infrared sensor alarm 4 is provided with a threaded section 41, which is used in conjunction with at least one locking nut 8 to ensure a stable installation. Preferably, a double locking nut 8 design is adopted, which is respectively located on both sides of the second connecting part 32, to enhance the stability of the connection and prevent loosening through a double locking mechanism.

[0038] Measures to enhance stability: A friction member 81 arranged in an annular shape and in a meshing shape is added to the side of the locking nut 8 close to the second connection part 32. The second connection part 32 is provided with a concave surface 322 that cooperates with the friction member 81, and the concave surface 322 has anti-slip textures. This further improves the stability of the installation, reduces the risk of loosening due to vibration or long-term use, and ensures the accuracy and reliability of infrared sensor monitoring.

[0039] The above structure proposes a detachable circular member 7, in which the circular member 7 and the rotating shaft 6 are detachably matched. The rotating shaft 6 has a hollow portion 62, and the circular member 7 is provided with a raised portion 72 which is matched with the hollow portion 62 and penetrates into the hollow portion 62. The raised portion 72 and the hollow portion 62 are fixed together by a locking bolt 9. The circular member 7 and the to-be-detected member 71 thereon can be replaced or repaired conveniently and quickly, thereby improving the maintainability of the equipment. Specifically, the plug-in structure is fixed with bolts, which not only enhances the stability of the connection, but also simplifies the installation and disassembly process, and reduces the possibility of failure due to looseness.

[0040] The infrared sensor alarm 4 provided in this embodiment works as follows:

[0041] Sensing movement: When the rotating shaft 6 rotates and drives the circular member 7 and the member to be detected 71 thereon to rotate, they will periodically pass through the detection surface of the infrared sensor. The infrared sensor can sense this movement and convert it into an electrical signal.

[0042] Signal processing: The electrical signal output by the infrared sensor is transmitted to the signal processing circuit. This circuit will amplify, filter and shape the signal to ensure the accuracy and stability of the signal.

[0043] Judgment and alarm: Once the signal processing circuit detects an abnormal signal, such as a sudden change in speed or a stop, it will trigger an alarm mechanism. The alarm mechanism may include sound and light alarms, sending signals to the central control system, etc., so as to promptly notify the operator or the automatic control system to take corresponding measures.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
