Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to an elevator speed limiter with an automatic scraping device for removing oil sludge and impurities from the rotating wheel. Background Technology

[0002] The speed governor is a core component of the elevator safety system, often referred to as the elevator's "speed police." It monitors the car's speed in real time, and when the speed exceeds 115% of the rated speed, the speed governor quickly sends a signal, cutting off the safety circuit and disconnecting the traction machine's power supply. Simultaneously, it activates the safety brake or the upward overspeed protection device, rapidly decelerating the elevator until it comes to a complete stop. This series of actions is completed in a very short time, effectively preventing safety accidents caused by overspeeding, thus providing strong protection for the safe operation of the elevator and safeguarding the lives of passengers and the normal operation of the equipment.

[0003] According to CN221459541U, an elevator safety gear speed governor linkage device is disclosed. This technology discloses "an elevator safety gear speed governor linkage device, including: a speed governor housing and a base, the speed governor housing being disposed at the upper end of the base; a cleaning mechanism, the cleaning mechanism being disposed inside the speed governor housing, the surface of the cleaning mechanism extending to the lower end of the base; wherein, the cleaning mechanism includes a cleaning component disposed inside the speed governor housing, the surface of the cleaning component being sleeved with a steel wire rope," etc., which has the technical effect of "when working, under the action of the cleaning component, it can clean the groove on the surface of the wheel. Under the action of the pulley and the transmission belt, the rotating rod is driven to rotate synchronously. At this time, the rotating block will drive the steel wire brush to rotate under the drive of the rotating rod, so that the upper end of the steel wire brush rotates in the opposite direction to the lower end of the wheel, achieving a good cleaning effect, thereby reducing the accumulation of oil and sludge impurities, and thus ensuring the normal use effect of the speed governor."

[0004] The above solution uses a wire brush to clean the internal rollers of the speed governor. However, since the operation of the wire brush depends entirely on the transmission of the rollers, and the two maintain continuous contact, this constant friction not only drastically accelerates the wear process of both the rollers and the wire brush, but also the potential decline in accuracy caused by roller wear will directly affect the overall performance of the speed governor, thus posing a potential threat to the safe operation of the elevator. On the other hand, frequent wear of the wire brush indicates a shorter replacement cycle, which undoubtedly increases the maintenance burden of the equipment and drives up operating costs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an elevator speed governor with an automatic scraping device for removing sludge and impurities from the rotating wheel. The output end of an electric push rod extends and retracts to drive the scraper head on the bracket to contact the rotating wheel. This allows the scraper head to remove sludge and impurities from the surface of the speed governor's main body as it rotates clockwise, ensuring the normal operation of the speed governor. After maintenance, the output end of the electric push rod extends and retracts to disengage the scraper head from the rotating wheel, resetting it to its original position and preventing continuous friction and wear.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an elevator speed governor with an automatic scraping device for removing oil sludge and impurities from the rotating wheel, comprising a speed governor body, a base fixed to the bottom of the speed governor body, and a cleaning mechanism on the speed governor body for cleaning oil sludge and impurities from the rotating wheel in the speed governor body, the cleaning mechanism comprising:

[0008] A collection component is installed on the speed limiter body and is used to collect the sludge and impurities that fall off the rotating wheel in the speed limiter body;

[0009] A fixing component, set on the base, is used to secure the collection components after installation.

[0010] Preferably, the bottom of the speed limiter body and the top of the base are provided with slots for inserting a collection component. The collection component includes a collection box that is inserted into the slot, and the upper end of the collection box has an edge.

[0011] Preferably, the collection assembly further includes clips fixed to the outer walls at both ends of the collection box.

[0015] Beneficial effects

[0016] This utility model provides an elevator speed governor with an automatic scraping device for removing sludge and impurities from the rotating wheel. Compared with the prior art, it has the following advantages:

[0017] 1. When the elevator is undergoing regular maintenance, and the wheel in the speed governor body is rotating clockwise, the output end of the electric push rod can extend and retract the drive shaft to drive the scraper on the bracket to contact the wheel. This allows the scraper to remove the oil and sludge adhering to the surface of the wheel during its clockwise rotation, ensuring the normal operation of the speed governor body. After maintenance, the output end of the electric push rod extends the drive shaft to disengage the scraper on the bracket from the wheel and reset it, avoiding continuous friction with the wheel and causing wear.

[0018] 2. Once the collection assembly is full, press the push button to disengage the buckle from the clip, thus releasing the collection assembly from the side of the base and allowing the collected oil and sludge impurities to be poured out. To reinstall the collection assembly, press the push button to engage the buckle and insert the collection assembly into the slots on both the bottom of the speed governor body and the top of the base. Release the push button, and the pressure from the torsion spring will push the button to rotate the buckle, causing it to engage the clip on the collection box, thus securing the installed collection assembly. The oil and sludge impurities on the speed governor body's rotating wheel, after being cleaned by the main assembly, will fall into the collection assembly below for collection, preventing contamination of other equipment in the elevator machine room.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 6 This utility model provides a technical solution: an elevator speed governor with an automatic scraping device for removing oil sludge and impurities from the rotating wheel, comprising a speed governor body 1, a base 2 fixed to the bottom of the speed governor body 1, and a cleaning mechanism 3 provided on the speed governor body 1 for cleaning oil sludge and impurities on the rotating wheel in the speed governor body 1. The cleaning mechanism 3 includes:

[0028] The main component 31 includes a mounting base 311 fixed inside the lower end of the speed limiter body 1. A bracket 312 is pivotally connected to the right end of the mounting base 311. A shaft 313 is rotatably mounted inside the bracket 312. A scraper head 314 is installed on the upper outer wall of the bracket 312. A shaft bracket 315 is fixed to the top left end of the mounting base 311. An electric push rod 316 is pivotally connected to the shaft bracket 315 and its output end is connected to the shaft 313.

[0029] The collection component 32 is installed on the speed limiter body 1 and is used to collect the oil sludge and impurities that have fallen off the rotating wheel in the speed limiter body 1.

[0030] The fixing component 33 is set on the base 2 and is used to fix the collection component 32 after installation.

[0031] In this implementation scheme, when the elevator is undergoing regular maintenance, and the wheel in the speed governor body 1 is rotating clockwise, the output end of the electric push rod 316 can extend and retract the drive shaft 313 to drive the scraper 314 on the bracket 312 to contact the wheel. This allows the scraper 314 to remove oil and sludge impurities adhering to the surface of the wheel during its clockwise rotation, ensuring the normal operation of the speed governor body 1. After maintenance, the output end of the electric push rod 316 extends the drive shaft 313 to disengage the scraper 314 on the bracket 312 from the wheel and reset it, avoiding continuous friction with the wheel and causing wear.

[0032] Specifically, the bottom of the speed limiter body 1 and the top of the base 2 are provided with slots for the insertion of the collection component 32. The collection component 32 includes a collection box 321 inserted into the slot, and the upper end of the collection box 321 is provided with an edge 322.

[0033] In this embodiment, after the oil sludge and impurities on the rotating wheel in the speed limiter body 1 are cleaned by the body component 31, they can fall into the collection component 32 below for collection, thus avoiding contamination of other equipment in the elevator machine room.

[0034] Specifically, the collection component 32 also includes clips 323 fixed to the outer walls at both ends of the collection box 321.

[0035] In this embodiment, after the collection component 32 is installed, the pressure of the torsion spring 335 pushing the dial 333 to drive the buckle 334 to rotate, so that the buckle 334 locks onto the clip 323 on the collection box 321, thereby fixing the installed collection component 32.

[0036] Specifically, the fixing component 33 includes a bearing 331 fixed on both sides of the upper end inside the base 2. A dial 333 is rotatably mounted on the lower end of the bearing 331 via a pin 332. A buckle 334 is fixed on the lower end of the dial 333 and cooperates with the locking head 323. A torsion spring 335 is sleeved on the pin 332.

[0037] In this embodiment, when the collection component 32 needs to be disassembled, the pressing head 333 can be pressed to drive the buckle 334 to disengage from the locking head 323, thereby releasing the fixation of the collection component 32, so that the collection component 32 can be taken out from one side of the base 2 and the oil sludge impurities collected inside can be poured out.

[0038] Specifically, the main component 31 also includes mounting holes 317 on both sides inside the scraper head 314, and the scraper head 314 is fixed to the bracket 312 by bolts through the mounting holes 317.

[0039] In this embodiment, the scraper head 314 can be disassembled and replaced after prolonged use and wear.

[0040] Specifically, the cleaning mechanism 3 also includes openings 34 inside the front and rear ends of the base 2.

[0041] In this embodiment, the opening 34 facilitates the insertion of a hand into the base 2 to press the lever 333.

[0042] The working principle and usage process of this utility model are as follows: First, when the elevator is being maintained regularly, and the wheel in the speed limiter body 1 is rotating clockwise, the output end of the electric push rod 316 can extend and retract the drive shaft 313 to drive the scraper head 314 on the bracket 312 to contact the wheel. This allows the scraper head 314 to scrape off the oil sludge and impurities attached to the surface of the wheel during its clockwise rotation, and the oil sludge and impurities fall into the collection component 32 below for collection.

[0043] After maintenance, the drive shaft 313 extends from the output end of the electric push rod 316 to drive the scraper 314 on the bracket 312 to disengage from the wheel and reset, so as to avoid continuous friction with the wheel and cause wear.

[0044] Finally, by pressing the lever 333, the buckle 334 is disengaged from the clip 323, thereby releasing the fixing of the collection component 32. This allows the collection component 32 to be removed from one side of the base 2, and the collected sludge and impurities inside can be poured out. When reinstalling the collection component 32, the lever 333 is pressed to move the clip 334, and the collection component 32 is inserted into the slots opened at the bottom of the speed limiter body 1 and the top of the base 2. The lever 333 is released, and the pressure of the torsion spring 335 pushes the lever 333 to rotate the clip 334, so that the clip 334 locks the clip 323 on the collection box 321, thereby fixing the installed collection component 32.
