[0002] The speed limiter is one of the main safety components of the elevator. Its function is to accurately track the elevator speed and act sensitively when overspeeding. It is the key to ensure the reliable operation of the speed limiter safety clamp system. However, the speed limiter calibration work is not only complicated, time-consuming and labor-intensive, but also has high requirements for the site where personnel work and the space for instrument installation. Some conventional speed limiter detectors cannot complete the calibration work for speed limiters installed in small spaces and relatively closed speed limiters. It usually takes at least 20 minutes to complete the detection of a speed limiter.

Moreover, when the semi-conical fixing ring is located in the conical sleeve, although the semi-conical fixing ring can be driven to move upward by friction, the semi-conical fixing ring is constantly in a fluffy state during the upward movement, and it is inconvenient for the wire rope to drive the semi-conical fixing ring to move out of the conical sleeve, which reduces the use effect of the device.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown:

[0026] An elevator speed governor quick rope release device comprises an elevator speed governor body 1, a steel wire rope 2 arranged on the elevator speed governor body 1 and a mounting seat 3 fixedly mounted on the elevator speed governor body 1, wherein a through hole for the steel wire rope 2 to pass through is opened on the surface of the mounting seat 3.

[0027] In this embodiment: the existing device {publication (announcement) number}: CN217417811U discloses a fast rope release device for an elevator speed limiter. In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the above-mentioned design, when in use, although the steel wire rope 2 is less worn, labor-saving and time-saving, and the labor intensity of the inspector is reduced, the two sets of semi-conical fixing rings cannot fit tightly with the steel wire rope 2, and it is difficult to drive the semi-conical fixing rings to be stuck in the conical sleeve 401, which affects the elevator speed limiter steel wire rope. The locking effect of the rope 2 is reduced, and when the semi-conical fixing ring is located in the conical sleeve 401, although the friction force can drive the semi-conical fixing ring to move upward, the semi-conical fixing ring is constantly in a fluffy state during the upward movement, and the wire rope 2 is inconvenient to drive the semi-conical fixing ring to move out of the conical sleeve 401, thereby reducing the use effect of the device. In terms of combined use, this problem is obviously a real problem that exists and is difficult to solve. Therefore, in order to solve this technical problem, a speed limiting component 4 is added to the application document. The electrical equipment involved in this product is powered by an external power supply.

[0028] More specifically:

[0029] like Figure 1-Figure 4 As shown:

[0030] A speed limiting assembly 4 is installed on the mounting seat 3, and the speed limiting assembly 4 includes a conical sleeve 401 fixed on the upper surface of the mounting seat 3, a semi-conical locking sleeve 402 arranged symmetrically above the conical sleeve 401, and an electromagnet 1 403 and an electromagnet 2 404 respectively arranged on one side of the two sets of semi-conical locking sleeves 402 close to each other and arranged symmetrically;

[0031] A symmetrically arranged U-shaped plate 409 is fixedly mounted on the upper surface of the mounting seat 3, a moving block 410 is slidably connected to the U-shaped plate 409, a symmetrically arranged fixed rod 406 is fixed to one side of the moving block 410, a sleeve rod 405 is sleeved on the outer surface of the fixed rod 406, two sets of sleeve rods 405 are fixedly connected to the semi-conical locking sleeve 402, and a spring 408 is arranged between the fixed rod 406 and the sleeve rod 405;

[0032] A guide rod 413 is fixedly installed between the two sets of sleeve rods 405 through a connecting plate, and a limiting groove 414 for inserting the guide rod 413 is opened on the surface of the U-shaped plate 409;

[0033] A speed measuring switch 415 is installed on the elevator speed limiter body 1, and a laser rangefinder 412 corresponding to the moving block 410 is fixed on the top of a set of U-shaped plates 409;

[0034] The surfaces of the two groups of semi-conical lock sleeves 402 are provided with rectangular grooves adapted to the electromagnet 1 403 and the electromagnet 2 404. The electromagnet 1 403 and the electromagnet 2 404 are both located in the rectangular grooves and fixedly connected to the semi-conical lock sleeves 402. The surface of the moving block 410 is provided with a moving hole adapted to the guide rod 413. The guide rod 413 and the moving block 410 are slidably connected through the moving hole. The electromagnet 1 403 and the electromagnet 2 404 are opposite magnetic poles.

[0035] The steel wire rope 2 passes through the conical sleeve 401 and is located between the two sets of semi-conical locking sleeves 402 .

[0036] In this embodiment: the elevator speed limiter quick rope release device, when in use, monitors the speed of the driving wheel of the wire rope 2 through the speed measuring switch 415. When a certain speed is reached, the electromagnet 1 403 and the electromagnet 2 404 are energized through the speed measuring switch 415 through a controller (not shown in the figure). Since the electromagnet 1 403 and the electromagnet 2 404 are opposite magnetic poles, the suction force generated thereby causes them to adsorb each other, thereby driving the two sets of semi-conical locking sleeves 402 to fit closely with the wire rope 2. The semi-conical locking sleeve 402 drives the sleeve rod 405 to slide on the fixed rod 406, and stretches the spring 408. As the sleeve rod 405 moves toward the direction of the wire rope 2, the sleeve rod 405 is pulled toward the wire rope 2. The guide rod 413 is driven by the connecting plate to move out of the limiting groove 414, thereby releasing the position lock of the moving block 410. Because the semi-conical locking sleeve 402 is tightly fitted with the steel wire rope 2 under the action of the electromagnet 1 403 and the electromagnet 2 404, while the steel wire rope 2 moves downward, the friction force drives the two groups of semi-conical locking sleeves 402 to be inserted into the inside of the conical sleeve 401. The semi-conical locking sleeves 402 are squeezed by the conical sleeve 401, and the friction force between the two groups of semi-conical locking sleeves 402 and the electric steel wire rope 2 increases. The steel wire rope 2 keeps driving the semi-conical locking sleeve 402 to move, and the friction force continues to increase until the semi-conical locking sleeve 402 can clamp and lock the steel wire rope 2.

[0037] When the speed limiter is checked, the elevator is started for maintenance and runs in the opposite direction. The semi-conical locking sleeve 402 moves upward. Under the action of electromagnet 1 403 and electromagnet 2 404, the two groups of semi-conical locking sleeves 402 are tightly fitted with the wire rope 2. At the same time, under the friction between the wire rope 2 and the semi-conical locking sleeve 402, the semi-conical locking sleeve 402 is driven to move out of the conical sleeve 401. In this process, the semi-conical locking sleeve 402 drives the moving block 410 to move upward through the sleeve rod 405 and the fixed rod 406. In this process, when the distance between the laser rangefinder 412 and the moving block 410 changes continuously, when a certain distance is reached, the laser rangefinder 412 cuts off the power to the electromagnet 1 403 and the electromagnet 2 404 on the semi-conical locking sleeve 402 through the controller. At this time, the electromagnet 1 403 and the electromagnet 2 404 lose their magnetism, and then under the elastic reset of the spring 408, the semi-conical locking sleeve 402 is driven to move upward. The movable spring 408 slides on the fixed rod 406, and the two groups of springs 408 drive the two groups of semi-conical locking sleeves 402 to move away from each other, releasing the fit of the semi-conical locking sleeve 402 to the steel wire rope 2, so that the semi-conical locking sleeve 402 and the steel wire rope 2 are separated from each other. Through the above operation, the semi-conical locking sleeve 402 can be closely fitted with the surface of the steel wire rope 2, so that the friction between the steel wire rope 2 and the semi-conical locking sleeve 402 can better drive the semi-conical locking sleeve 402 to be inserted into the conical sleeve 401, or the semi-conical locking sleeve 402 can be better pulled out from the conical sleeve 401, so that during the process of removing the semi-conical locking sleeve 402 from the conical sleeve 401, the semi-conical locking sleeve 402 is prevented from being removed from the conical sleeve 401 and becoming fluffy. After the semi-conical locking sleeve 402 is removed from the conical sleeve 401, it can be automatically separated from the steel wire rope 2, thereby improving the use effect of the device and meeting actual use needs.

[0038] It should be noted that: the laser rangefinder 412 can adopt the source constant (YHT) 40-100m model, and the speed switch 415 is the HD-RD-II-III model. It is necessary to ensure that the circuit connection between the speed switch 415 and the controller as well as the electromagnet 1 403 and the electromagnet 2 404 is ensured. According to the output signal characteristics of the speed switch 415 (such as voltage signal or current signal, signal range, etc.), the parameters of the controller are correctly set to ensure that the controller can correctly interpret the signal of the speed switch 415 and respond accordingly. It is necessary to program the controller to define how the controller responds when the speed switch 415 detects a specific speed or speed range. For example, a speed threshold is set. When the speed detected by the speed switch 415 exceeds this threshold, the controller will start to energize the electromagnet 1 403 and the electromagnet 2 404.

[0039] The laser rangefinder 412 needs to be properly connected to the controller, which usually involves connecting the signal line to ensure that the data measured by the laser rangefinder 412 can be transmitted to the controller, setting the corresponding parameters in the controller, such as the distance threshold, which will determine the distance measured by the laser rangefinder 412, and the controller will perform the corresponding action (for example, control the electromagnet to be powered on or off), and programming the controller to define how the controller should operate the electromagnet 1 403 and the electromagnet 2 404 when the distance measured by the laser rangefinder 412 reaches or falls below the set threshold, which may include turning on the electromagnet (powering on) or turning off the electromagnet (powering off).

[0040] Going further;

[0041] In an optional embodiment, symmetrically arranged limiting rods 411 are fixed inside the U-shaped plate 409 , and the moving block 410 slides on the surface of the limiting rod 411 through the through holes.

[0042] In this embodiment: the fixed rod 406 drives the moving block 410 to slide stably on the two sets of limiting rods 411, thereby improving the stability of the semi-conical locking sleeve 402 on the wire rope 2.

[0043] Going further;

[0044] In an optional embodiment, the sleeve rod 405 slides on the surface of the fixed rod 406 through a circular groove, the surface of the fixed rod 406 is sleeved and fixed with an annular piece 407, the spring 408 is sleeved on the surface of the fixed rod 406, and the two ends of the spring 408 are fixedly connected to the annular piece 407 and the sleeve rod 405 respectively.

[0045] In this embodiment, the spring 408 is connected to the sleeve rod 405 via the annular sheet 407 to fix the spring 408 .

[0046] Going further;

[0047] In an optional embodiment, the conical sleeve 401 is divided into two from the center, and the two groups of semi-annular conical sleeves 401 are fixedly connected by bolts.

[0048] In this embodiment: the conical sleeve 401 is divided into two parts from the center. When installing the conical sleeve 401, the two groups of semi-annular conical sleeves 401 are fixed by bolts and then fixed on the mounting seat 3. The two groups of semi-annular conical sleeves 401 are thought of as a ring structure and connected by bolts. Compared with the open conical sleeve 401 in the prior art, the semi-conical locking sleeve 402 is easy to deform when it enters the conical sleeve 401, while this structure is not easy to deform, thereby improving the overall strength.

[0049] Working principle and use process of the utility model: When the elevator speed limiter quick rope loosening device is in use, the speed measuring switch 415 is used to monitor the speed of the driving wheel of the steel wire rope 2. When a certain speed is reached, the speed measuring switch 415 is used to energize the electromagnet 1 403 and the electromagnet 2 404 through the controller (not shown in the figure). Since the electromagnet 1 403 and the electromagnet 2 404 are opposite magnetic poles, the suction force generated thereby causes mutual adsorption, thereby driving the two groups of semi-conical locking sleeves 402 to fit closely with the steel wire rope 2, and the sleeve rod 405 is driven to slide on the fixed rod 406 through the semi-conical locking sleeve 402, and the spring 408 is stretched. As the sleeve rod 405 moves toward the direction of the steel wire rope 2, the guide rod 41 is driven through the connecting plate. 3 is moved out of the limiting groove 414, thereby releasing the position lock of the moving block 410. Due to the action of the electromagnet 1 403 and the electromagnet 2 404, the semi-conical locking sleeve 402 is closely fitted with the wire rope 2. When the wire rope 2 moves downward, the friction force drives the two groups of semi-conical locking sleeves 402 to be inserted into the inside of the conical sleeve 401. The semi-conical locking sleeves 402 are squeezed by the conical sleeve 401, and the friction force between the two groups of semi-conical locking sleeves 402 and the electric wire rope 2 increases. The wire rope 2 keeps driving the semi-conical locking sleeves 402 to move, and the friction force continues to increase until the semi-conical locking sleeves 402 can clamp and lock the wire rope 2. When the speed limiter verification is completed, the elevator is started for maintenance to run the semi-conical locking sleeves 402 in the opposite direction. The semi-conical locking sleeve 402 moves upward, and under the action of the electromagnet 1 403 and the electromagnet 2 404, the two groups of semi-conical locking sleeves 402 are tightly fitted with the steel wire rope 2. At the same time, under the friction between the steel wire rope 2 and the semi-conical locking sleeve 402, the semi-conical locking sleeve 402 is driven to move out of the conical sleeve 401. In this process, the semi-conical locking sleeve 402 drives the moving block 410 to move upward through the sleeve rod 405 and the fixed rod 406. In this process, when the distance between the laser rangefinder 412 and the moving block 410 changes continuously, when a certain distance is reached, the laser rangefinder 412 cuts off the power to the electromagnet 1 403 and the electromagnet 2 404 on the semi-conical locking sleeve 402 through the controller. At this time, the electromagnet 1 403 and the electromagnet 2 404 lose their magnetism, and then The spring 408 is elastically reset, thereby driving the spring 408 to slide on the fixing rod 406, and the two groups of springs 408 drive the two groups of semi-conical locking sleeves 402 to move away from each other, releasing the fit of the semi-conical locking sleeve 402 to the steel wire rope 2, so that the semi-conical locking sleeve 402 and the steel wire rope 2 are separated from each other. Through the above operation, the semi-conical locking sleeve 402 can be closely fitted to the surface of the steel wire rope 2, so that the friction between the steel wire rope 2 and the semi-conical locking sleeve 402 can better drive the semi-conical locking sleeve 402 to be inserted into the conical sleeve 401, or the semi-conical locking sleeve 402 can be better pulled out from the conical sleeve 401, so that during the process of removing the semi-conical locking sleeve 402 from the conical sleeve 401, the semi-conical locking sleeve 402 is prevented from being removed from the conical sleeve 401 and becoming fluffy.After the semi-conical locking sleeve 402 is removed from the conical sleeve 401, it can be automatically separated from the wire rope 2, thereby improving the use effect of the device and meeting the actual use requirements.
