Description

Technical Field

[0001] The utility model belongs to the technical field of elevator safety facilities, and in particular relates to an auxiliary safety device for an emergency evacuation passage of an inclined elevator. Background Art

[0002] The aforementioned inclined elevator belongs to the category of special elevators, and is mainly but not limited to being used in scenic spots, hillsides, light rails, subways, ports, etc. Its working principle is to use the friction between the wire rope and the traction wheel to enable the inclined elevator car and the counterweight to run along the inclined track, so as to achieve the purpose of transporting people and / or goods.

[0003] Technical information on inclined elevators can be found in the public Chinese patent documents, such as CN201494989U (an inclined elevator), CN203976176U (an inclined double-car elevator without counterweight) and CN101992990A (a double inclined traction elevator), etc. As for subways or high-speed railways, inclined elevators are often used due to space limitations, such as Beijing Badaling Great Wall Station, Macau Datanshan Station, Suzhou Metro Laodong Road Station, etc., all of which use inclined elevators to reach the platform from the waiting area and vice versa. In addition, inclined elevators can also provide convenience for special groups such as wheelchair users.

[0004] As is known to all, sudden failures are unavoidable in inclined elevators during daily use, such as control system failures, mechanical component failures, power failures, etc. Setting up an emergency evacuation passage on the passage where the inclined elevator car runs, i.e., between a pair of guide rails with the guide rail fixing columns of the guide rail structural system as carriers, can provide convenience for evacuating personnel to evacuate quickly and safely. Specifically, when a failure situation other than the above examples occurs, the inclined elevator car is forced to stay on the guide rail in an area that is not a normal stop area. After the inclined elevator car door (also called the "end door") is opened, the passengers evacuate from the car door and reach the platform or other similar safe areas along the emergency evacuation passage.

[0005] A typical example of the aforementioned emergency evacuation passage is the patent application number CN219098423U, entitled "An emergency evacuation passage structure for a front-door inclined elevator", proposed by the present applicant. Since the patent innovatively uses the structure described in paragraph 0006 of the specification, it objectively has the technical effects described in paragraph 0014 of the specification. Specifically, when an inclined elevator suddenly fails and stops on the running guide rail of the inclined elevator car, the passengers can walk out of the car after the car door is opened and walk along the pedal body to the platform (downward) or to the waiting room (upward) and other safe areas.

[0006] In short, the above CN219098423U can be suitable for occasions other than those listed above. However, as people's enthusiasm for sightseeing in scenic spots and historical sites continues to rise in recent years, they have become an indispensable part of enriching their lives and cannot be replaced by any other form or factor. As a result, the use of inclined elevators or the number of social holdings has increased year by year. At the same time, since the sightseeing inclined elevators are used outdoors, their failure probability is usually higher than that of the inclined elevators used indoors, such as subways. Therefore, the applicant seems to focus on the description of outdoor inclined elevators below, but it does not mean that the auxiliary safety device of the emergency evacuation passage of inclined elevators used in various occasions indoors is excluded.

[0007] As people know, since many scenic spots and historical sites are located among the mountains, because the trend of population aging in my country is rapidly intensifying, and because the proportion of elderly people in the tourist group is increasing year by year, in order to facilitate the elderly to climb high and enjoy the scenery, the inclined elevators used for sightseeing have grown at an alarming rate. A typical example is the world's longest inclined elevator in Enshi, Hubei (total length 380m, vertical height 300m, operating angle 47°, operating speed 1.5-2.5m / s, each car can accommodate 26 people, and the one-way running time is 3-4min), which was put into use on May 1, 2021. Emergency evacuation passages with different structures are also provided on the operating channel of the inclined elevator.

[0008] The emergency evacuation passages of inclined elevators in the prior art, including the above-mentioned CN219098423U, have the following disadvantages: since the emergency evacuation passages rely only on the pedal body (i.e., the step) for the evacuees to evacuate in a hurry or even in a running manner toward the platform and other safe areas, there is nothing to rely on on both sides of the emergency evacuation passages, that is, there is no handhold for people to temporarily grasp to avoid falling, and the emergency evacuation passages of inclined elevators are inclined, and usually form an angle of 15° to 75° with the horizontal plane, which is essentially different from evacuation on a flat road. For example, emergency evacuees often have fearful and nervous psychological factors, and for women, children, the elderly or the elderly, there is a relatively large risk of falling. Of course, if a guardrail can be set on the opposite side, i.e., the side facing outward, of a pair of support ribs parallel to each other in the length direction of the structural system of the pedal assembly of the above-mentioned CN219098423U, then the above-mentioned problems seem to be solved. However, if the guardrail is set in the above manner, it will bring about the problem of losing one thing while taking care of another. The so-called one thing is to ensure that the evacuees can pass along the pedal body to the station and other safe areas while holding the guardrail. The so-called losing the other is that the setting of the guardrail will interfere with the passage of the inclined elevator car, and the setting of the guardrail will also affect the sight of the tourists in the car to a certain extent, that is, it will interfere with the dynamic visual sight of the tourists. Of course, for the inclined elevator used in the subway, the setting of the guardrail may cause the passengers in the inclined elevator car to worry or even fear because of the passing guardrail.

[0009] Based on the above, how to find a reasonable balance between temporarily stopping the operation of the car in an emergency and ensuring the rapid, timely and safe evacuation of the passengers in the car and avoiding interference with the operation of the car and the sightseeing of the passengers in the car under normal use has become a technical problem that the industry is concerned about and hopes to solve. The technical solution to be introduced below was produced in this context. Utility Model Content

[0027] In order to more clearly understand the technical essence and beneficial effects of the present invention, the applicant provides a detailed description in the form of embodiments below. However, the description of the embodiments is not a limitation on the present invention. Any equivalent changes made based on the concept of the present invention that are merely formal and not substantial should be regarded as within the scope of the technical solution of the present invention.

[0028] In the following description, all concepts of direction or orientation (unless otherwise specified) involving up, down, left, right, front and back are based on the current Figure 1 The position state is taken as a reference, and therefore it cannot be understood as a special limitation on the technical solution provided by the utility model.

[0029] See also Figure 1 , showing the structural system of the emergency evacuation passage of the inclined elevator, which is arranged on the side of the guide rail fixed column supporting the cross beam 11 facing upward between the opposite sides of the guide rail fixed columns 1 distributed at intervals in a face-to-face state; showing the structural system of the auxiliary safety device as the technical key point of the utility model, which is arranged in an interval state along the length direction of the aforementioned pedal mechanism 2 facing backward, and each two adjacent anti-fall mechanisms 3 are connected by a connecting protection rod 4, wherein, when the inclined elevator car is in a normal driving state (i.e., a fault-free state), the aforementioned anti-fall mechanism 3 is formed by Figure 4 As shown, the anti-fall mechanism 3 is placed horizontally and abuts against the side of the pedal mechanism 2 facing backward in the length direction. When a sudden failure occurs in the inclined elevator and the inclined elevator car is in an emergency stop state, the anti-fall mechanism 3 is transformed from a horizontal position to a vertical position. Figure 1 and Figure 5 The vertical state shown in the figure serves as a guardrail for the evacuees who are leaving the inclined elevator car to grasp and evacuate to the safe area along the pedal mechanism 2. The safe area referred to here is: when the right door of the inclined elevator car is open, the evacuees evacuate to the station area to the right along the pedal mechanism 2 after leaving the inclined elevator car, and vice versa.

The intermediate linkage rods 33 are a group that are spaced apart and longitudinally parallel to each other in the vertical state. Although three are shown in this embodiment, it is not limited by this quantity. More specifically, the example in this embodiment is a "ri" shape deflected by 90°, but it can completely be an "mu" shape deflected by 90°, etc. The upper ends of the illustrated intermediate linkage rods 33 are hinged to the upper connecting rod 31 by a pair of upper hinge pieces 331 of the intermediate linkage rod at positions corresponding to the front side and the rear side of the upper connecting rod 31 respectively, and the lower ends of the intermediate linkage rods 33 are hinged to the lower connecting rod 32 by a pair of lower hinge pieces 332 of the intermediate linkage rod at positions corresponding to the front side and the rear side of the lower connecting rod 32 respectively. And the length direction of the lower connecting rod 32 is fixed to the side facing the rear of the length direction of the aforementioned pedal mechanism 2. The intermediate linkage rod locking and releasing mechanism 34 is arranged at the left end of the aforementioned upper connecting rod 31 and is hinged to the leftmost intermediate linkage rod 33 from left to right between the upper and lower connecting rods 31 and 32. The aforementioned upper connecting rod 31 has an upper connecting rod hollow cavity 311; the right end of the aforementioned connecting and protecting rod 4 is connected to the left end of the upper connecting rod 31, and the left end of the connecting and protecting rod 4 corresponds to and is connected or disconnected from the upper connecting rod hollow cavity 311 of the upper connecting rod 31 of the adjacent anti-fall mechanism 3. Among them, when the aforementioned anti-fall mechanism 3 is in the lying state shown by Figure 4 and is abutted against the side facing the rear of the length direction of the aforementioned pedal mechanism 2, the left end of the aforementioned connecting and protecting rod 4 is disconnected from the connection with the upper connecting rod 31 of the adjacent anti-fall mechanism 3, that is, the left one of the anti-fall mechanisms 3 in the position state shown by Figure 1 and is inserted into the aforementioned upper connecting rod hollow cavity 311. And when the aforementioned anti-fall mechanism 3 is transformed from the lying state to the vertical state shown by Figure 5 and serves as a guardrail for evacuating personnel walking out of the inclined elevator car to hold, the left end of the aforementioned connecting and protecting rod 4 retreats from the upper connecting rod hollow cavity 311 of the adjacent upper connecting rod 31 to the end of the upper connecting rod 31 and is fixedly connected at the end position.

In Figure 4 shown state, Figure 1The aforementioned left end limiting screw 42 of the connecting protection rod is changed to correspond to the aforementioned connecting protection rod end limiting screw hole 313 and the connecting protection rod right screw hole 44 opened at the right end of the connecting protection rod 4 to limit the right end of the connecting protection rod 4. In this state, the left end of the connecting protection rod 4 is inserted into the upper connecting rod cavity 311 of the upper connecting rod 31 of the adjacent anti-fall mechanism 3. It can be seen from the above that: the left end of the connecting protection rod 4 is provided with a connecting protection rod left screw hole 43, and the right end of the connecting protection rod 4 is provided with a connecting protection rod right screw hole 44. When the anti-fall mechanism 3 is in a lying state ( Figure 4 ), the right screw hole 44 of the aforementioned connection protection rod corresponds to the screw hole 313 defined at the end of the aforementioned connection protection rod, and when the anti-fall mechanism 3 is in a vertical state ( Figure 1 and Figure 5 ), the left screw hole 43 of the aforementioned connection protection rod corresponds to the limited screw hole 313 at the end of the connection protection rod.

[0032] In this embodiment, the cross-section of the upper and lower connecting rods 31, 32, the middle connecting rod 33 and the connecting protection rod 4 is in the shape of a middle rectangle. In particular, the upper connecting rod 31 and the connecting protection rod 4 are designed to be hollow and have a cross-section in the shape of a square, which can help emergency evacuees to grip them reliably, that is, they will not slip due to the presence of edges, and fully ensure safety.

[0041] See also Figure 4 and Figure 5 And combined with Figures 1 to 3 As mentioned above, when the inclined elevator is in normal use, that is, in normal operation, the anti-fall mechanism 3 of the utility model is in Figure 4 In the state shown, specifically, the auxiliary safety device of the utility model, which is composed of the upper and lower connecting rods 31, 32, the middle connecting rod 33 and the connecting protection rod 4, is in a lying state and tends to be close to the rear side of the rear one of the pair of pedal fixing beams 21 of the structural system of the pedal mechanism 2 to be mentioned below. However, when any of the sudden failures mentioned by the applicant in the background technology column above occurs, the anti-fall mechanism 3 of the utility model can be manually operated. Figure 4 The state shown changes from Figure 5 In the state shown, the anti-fall mechanism 3 is Figure 4 The state changes to Figure 1 and Figure 5 The process of the state (use state) shown is: the staff or other relevant personnel such as the driver who walks out of the inclined elevator car grasps the upper connecting rod 31 and / or the intermediate connecting rod locking release mechanism 34 by hand until the intermediate connecting rod 33 is in an upright state. In this state, since the operator leaves or releases the grip of the locking and unlocking handle 343, a pair of handle return springs 344 exerts a reaction force (spring return force) on the locking and unlocking handle 343, so that the pin 3432 is inserted into the pin hole 34111, thereby completing the anti-fall mechanism 3. Figure 4 The status changes to Figure 1 and Figure 5 The state of the guardrail effect. Since a group of middle connecting rods 33 are in a longitudinally erected state at this time, the connecting protection rod 4 is withdrawn from the upper connecting rod cavity 311 of the upper connecting rod 31 of the adjacent anti-fall mechanism 3 to the extent that the left screw hole 43 of the connecting protection rod on it corresponds to or overlaps with the limiting screw hole 313 at the end of the connecting protection rod, and the left limiting screw 42 of the connecting protection rod is screwed in as described above by the applicant. In the aforementioned state, the evacuees in the inclined elevator car evacuate along the pedal mechanism 2 while holding the upper connecting rod 31 and the connecting protection rod 4. When the evacuees are in Figure 1 and Figure 5 The anti-fall mechanism 3 in the state returns to Figure 4When the locking and unlocking handle 343 is in the state shown in the figure, the operator only needs to squeeze the locking and unlocking handle 343 of the intermediate link locking and releasing mechanism 34 and move it upward. When it moves upward, the pair of handle return springs 344 are compressed, and the locking and unlocking handle 343 moves upward. When the locking and unlocking handle 343 moves upward to the extent that the latch 3432 exits the latch hole 34111, a slight force is applied to push the intermediate link locking and releasing mechanism 34 to the right, so that the entire anti-fall mechanism 3 can be transformed from the state of Figure 4 In the state shown, the operator just needs to leave the intermediate linkage rod locking release mechanism 34 .

[0042] Depend on Figure 1 As shown, inclined elevator car running guide rails 5 are fixed to the upper parts of the opposite sides of the aforementioned guide rail fixing columns 1 which are distributed at intervals in a face-to-face state. The operation of the inclined elevator car is realized on a pair of inclined elevator car running guide rails 5.

The pair of pedal fixing beams 21 together with the aforementioned pedal board 22 are fixed to the upper side of the aforementioned guide rail fixing column supporting beam 11, and anti-slip flanges 221 are densely formed on the surface of the pedal board 22.

[0044] Emergency evacuation personnel follow Figure 1 The person shown walking on the pedal 22 (walkway) walks until he reaches a station or base station or other similar safety area.

[0045] In summary, the technical solution provided by the utility model makes up for the shortcomings of the existing technology, successfully completes the invention task, and faithfully realizes the technical effects stated by the applicant in the technical effect column above.
