Description

Technical Field

[0001] This utility model relates to a shaft sealing device, and more specifically, to a shaft head protection device applied on a sorting line. Background Technology

[0002] In various manufacturing enterprises, sorting lines are an important and ubiquitous piece of equipment, and drives (such as motors and gearboxes) serve as the power source, the "heart" of the sorting line. Currently, the models and types of drives on the market vary, resulting in structural differences. For example, some drive shafts are hidden inside the equipment, while others are exposed. For instance, in tobacco sorting companies, the sorting lines primarily rely on a combination of a motor and a gearbox for drive. However, some gearboxes have exposed shafts, and due to workshop layout constraints, some gearbox shafts face worker / visitor passageways. If workers or visitors do not notice these exposed shafts and approach the equipment, safety accidents can easily occur. Therefore, enterprise safety management regulations have increased the requirements for managing these hazards. However, there are currently few safety protection devices specifically designed for drive shafts on the market; therefore, we have designed a shaft protection device for use on sorting lines. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a shaft head protection device for use on sorting lines to prevent safety hazards caused by exposed shaft heads, in order to address the shortcomings of existing technologies.

[0004] The present invention discloses a shaft head protection device for use on a sorting line, comprising a protective plate, which is detachably installed on one side of the shaft head of a driver and forms a full coverage of the shaft head. The protective plate has a bent portion facing the shaft head to provide a safe distance between the protective plate and the shaft head. An electric drive device connected to the shaft head is provided in the safe distance, and an indicator is installed on the bent portion. The electric drive device is electrically connected to the indicator.

[0005] Preferably, the protective plate has at least two through holes, and the driver on the periphery of the shaft head has a threaded hole. A bolt is inserted into the through hole and screwed into the threaded hole.

[0006] Preferably, the bolt is screwed with an anti-loosening nut.

[0007] Preferably, the protective plate has bent portions on both opposite sides, and the end of the bent portion away from the protective plate is in contact with the end face of the driver.

[0008] Preferably, the end of the bent portion away from the protective plate is provided with an arc-shaped relief groove, and the width of the arc-shaped relief groove is greater than the width of the shaft head bearing.

[0009] Preferably, the bent portion and the protective plate are an integral structure.

[0010] Preferably, the electric drive device includes a generator and a voltage regulator module. The generator is fixedly mounted on the protective plate.

[0021] The present invention will be further described below with reference to embodiments, but this does not constitute any limitation on the present invention. Any limited modifications made by any person within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0022] See Figures 1-3 This utility model discloses a shaft end protection device applied to a sorting line, comprising a protective plate 2. The protective plate 2 is detachably installed on one side of the shaft end 11 of the driver 1, and forms a complete cover over the shaft end 11, effectively concealing it and preventing safety hazards caused by its exposure, thus complying with relevant enterprise safety production management regulations. The protective plate 2 has a bent portion 3 facing the shaft end 11, creating a safe distance between the protective plate 2 and the shaft end 11, thereby preventing collisions and providing excellent protection for the driver 1. An electric drive device 7 is installed within the safe distance, and a warning device 9 is installed on the bent portion 3. The electric drive device 7 is electrically connected to the warning device 9, providing additional warning and better preventing safety accidents. The driver 1 can be a motor or a speed reducer. In this embodiment, the protective plate is mainly installed on the exposed gearbox of the shaft end.

[0023] The following is a detailed description of each of the above components.

[0024] Regarding the detachable installation of the protective plate 2, the protective plate 2 in this embodiment has at least two through holes, and the driver 1 on the periphery of the shaft head 11 has a threaded hole. A bolt 4 is inserted into the through hole and screwed into the threaded hole.

[0025] To prevent bolt 4 from loosening due to mechanical vibration, a lock nut 5 is screwed onto bolt 4.

[0026] In this embodiment, the protective plate 2 has bends 3 on both opposite sides, and the end of the bend 3 away from the protective plate 2 is in contact with the end face of the driver 1. By having the two bends 3 abut against the end face of the driver 1, a safe distance between the protective plate 2 and the shaft head 11 is ensured, and the stability of the protective plate 2 installation is also improved.

[0027] Since most of the shaft heads 11 on the driver 1 are installed by bearings, in order to avoid the influence of the bending part 3 on the bearing, in this embodiment, an arc-shaped relief groove 6 is provided at the end of the bending part 3 away from the protective plate 2, and the width of the arc-shaped relief groove 6 is greater than the width of the bearing of the shaft head 11.

[0028] In this embodiment, the bending part 3 and the protective plate 2 are an integral structure, which greatly improves the overall rigidity of the shaft head protection device.

[0029] The electric drive unit 7 includes a generator and a voltage regulator module. The generator is fixedly mounted on the protective plate 2, and its shaft is connected to the shaft head 11 via a coupling 8. The generator's output terminal is electrically connected to the input terminal of the voltage regulator module, and the output terminal of the voltage regulator module is electrically connected to the input terminal of the indicator 9. The generator is driven by the driver 1 to generate electricity, which is then regulated by the voltage regulator module and input to the indicator 9 to issue a warning, preventing personnel from approaching these potentially dangerous locations. It should be noted that in field use, the operating speed of the motor / reducer and other equipment is relatively stable, thus enabling the generator to operate at a relatively stable speed, generating electricity to power the indicator 9, eliminating the need for a battery. After the equipment stops operating, the indicator 9 also loses power and ceases operation, requiring no manual operation, greatly improving the device's practicality. Furthermore, it requires minimal modification to the field equipment, resulting in low cost and minimal manual / control intervention, perfectly aligning with current enterprise safety management standards.

[0030] As a further improvement, indicator 9 is an indicator light, which is mounted on the bend 3 facing the ground. In enterprises with strict environmental requirements, such as tobacco sorting enterprises, the floors are often paved with green paint, and the entire floor is glossy. Therefore, mounting the indicator light on the bend 3 facing the ground allows it to be observed by on-site personnel through ground reflection, and also avoids the glare problem caused by its installation above the device when lit. At the same time, it can also effectively prevent misjudgment caused by its mixing with other lights on the equipment.

[0031] Furthermore, the output of the voltage regulator module is electrically connected to the input of the indicator 9 via a flasher, so that the indicator light works in a flashing state, which can better serve as a prompt.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
