Description

Technical Field

[0001] This application relates to the field of elevator technology, specifically to an elevator speed limiter. Background Technology

[0002] The main function of an elevator speed governor is to monitor and control the speed of the elevator car. When the elevator exceeds its speed for some reason during operation, or even poses a risk of falling, and all other safety protection devices fail, the speed governor will work in conjunction with the safety brake to bring the elevator car to an emergency stop, thereby preventing personal injury and equipment damage.

[0003] For example, patent CN206511776U discloses an elevator speed governor. This patent uses a self-locking principle, employing a self-locking hydraulic rod to connect the centrifugal rod and the main rod. When the centrifugal rod is thrown out, the self-locking hydraulic rod extends to a certain length and then self-locks, so that the ratchet on the centrifugal rod steadily engages the ratchet wheel. This solves the problem of the inevitable elasticity decay of the spring itself, making the speed governor work more reliable and stable.

[0004] When using elevator speed governors, staff may indeed need to disassemble and inspect them. However, during the disassembly process, especially the bolt-locked parts, each bolt needs to be removed one by one. This process consumes a lot of time and effort and reduces work efficiency. In particular, in emergency repairs or emergency repairs, this tedious disassembly process may delay the repair progress.

[0005] Therefore, it is necessary to provide an elevator speed limiter to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0034] like Figures 1-2 As shown, this application provides an elevator speed governor, including a base 1 and an elevator speed governor 3 disposed on the upper end of the base 1, and the base 1 is fixed with external fasteners so as to maintain stability during the use of the elevator speed governor 3.

[0035] Meanwhile, in order to facilitate disassembly and maintenance by staff, a quick-release mechanism 2 is provided between the base 1 and the elevator speed limiter 3. The quick-release mechanism 2 includes a fixing plate 20 fixedly installed on the upper end of the base 1, and a positioning post 21 fixedly installed on the fixing plate 20. The top of the positioning post 21 is grooved so that it can be initially positioned for use later.

[0036] Furthermore, an installation plate 22 is fixedly installed at the lower end of the elevator speed limiter 3, and a stabilizing column 23 is fixedly installed at the lower end of the installation plate 22. The top of the stabilizing column 23 is protruding, and the protruding top of the stabilizing column 23 is adapted to the grooved part at the top of the positioning column 21, so as to facilitate subsequent positioning and stable installation.

[0037] For subsequent installation and locking, such as Figures 2-4 As shown, a locking assembly 24 is provided between the mounting plate 22 and the fixing plate 20. The locking assembly 24 includes a through hole 240 opened on the mounting plate 22, and a fixing sleeve 245 is fixedly provided on the mounting plate 22 at the upper end of the through hole 240. The fixing sleeve 245 is hollow.

[0038] Furthermore, a locking pin 248 is slidably disposed inside the fixing sleeve 245. The locking pin 248 passes through the fixing sleeve 245 and extends through the through hole 240 to the other end of the mounting plate 22. At the same time, a blocking ring 253 is fixedly disposed at one end of the locking pin 248. The blocking ring 253 is used to prevent the locking pin 248 from sliding out of the fixing sleeve 245.

[0039] A spring 247 is fixedly installed between the blocking ring 253 and the fixing sleeve 245. The spring 247 is located outside the locking post 248. At the same time, a protruding block 252 is provided at the other end of the locking post 248. The protruding block 252 is a conical surface with a larger upper end and a smaller lower end. A step is formed between the upper end of the protruding block 252 and the locking post 248. Thus, the operator can push the locking post 248 through the through hole 240 to the other end of the mounting plate 22 by pressing the locking post 248. At the same time, the spring 247 is compressed.

[0040] Meanwhile, in order to lock the elevator speed governor, a mounting hole 254 is provided on the fixing plate 20 corresponding to the through hole 240, and a fixing ring 241 is rotatably set at the lower end of the mounting hole 254. A handle 244 is fixedly set at one end of the fixing ring 241 so that the operator can push the handle 244 to drive the fixing ring 241 to rotate at the lower end of the mounting hole 254. A plastic rod 242 is fixedly set at the upper end of the fixing ring 241. The plastic rod 242 passes through the mounting hole 254, and a locking block 243 is fixedly set at the end of the plastic rod 242 that passes through the mounting hole 254. Thus, the operator can push the handle 244 to drive the fixing ring 241 to rotate at the lower end of the mounting hole 254, thereby causing the locking block 243 to rotate accordingly.

[0041] Therefore, when locking is required, the operator can press the locking pin 248 to move it vertically downward, so that the protruding block 252 at one end of the locking pin 248 passes through the through hole 240. Under continuous pressing, because the surface of the protruding block 252 is arc-shaped, it will push the locking block 243 at the top of the plastic rod 242 to both sides. When the protruding block 252 moves away from the locking block 243, the locking blocks 243 on both sides will move closer to the locking pin 248 again.

[0042] When the surface of the protruding block 252 touches the mounting hole 254, the operator stops pressing. At this time, the spring 247 releases its compression, causing the locking pin 248 to move vertically upward. At the same time, the locking block 243 at the top of the plastic rod 242 will lock the step formed between the protruding block 252 and the locking pin 248 to achieve the locking effect.

[0043] In order to facilitate quick unlocking, openings 246 are provided on both sides of the protruding block 252 (e.g., ...). Figure 4 As shown in the figure, the size of the opening slot 246 is adapted to the size of the locking block 243. When unlocking is required, the operator only needs to push the handle 244 to drive the locking block 243 to rotate through the fixing ring 241 until the locking block 243 is moved to the opening slot 246, so that the locking block 243 can be dislodged, thereby achieving the purpose of unlocking.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
