Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and more specifically, to a passenger elevator with short-circuit protection function. Background Technology

[0002] In the design of passenger elevators, the car top control cabinet is the core component of the elevator control system. It usually contains electrical components such as circuit breakers. The circuit breaker is connected in series in the main circuit of the control circuit for short circuit protection. However, during the operation of the elevator, the electrical components inside the control cabinet will generate a lot of heat. If this heat cannot be dissipated in time, it may cause the circuit breaker to overheat, which may lead to failure and seriously affect the safety and reliability of the elevator. In order to effectively dissipate heat, the existing technology generally opens heat dissipation vents on the car top control cabinet to promote natural convection or forced air cooling of heat inside the cabinet and reduce the occurrence of circuit breaker failures.

[0003] However, while heat dissipation vents facilitate heat removal, they also become potential channels for dust and debris to enter the control cabinet. To prevent dust accumulation from affecting the performance and lifespan of electrical components, filters are typically installed at the vents to block dust. While these filters are effective, they gradually become clogged over time, requiring regular cleaning to maintain their permeability. In existing technologies, multiple filters are often installed individually, requiring disassembly and reinstallation one by one for cleaning. This process is not only time-consuming and labor-intensive but also increases operational difficulty and maintenance costs. Therefore, we propose an improvement by introducing a passenger elevator with short-circuit protection. Utility Model Content

[0004] The purpose of this utility model is to address the problem that cleaning filters requires disassembling and reassembling each filter individually, which is time-consuming and labor-intensive.

[0005] To achieve the above-mentioned objectives, this utility model provides a passenger elevator with short-circuit protection to improve the aforementioned problems.

[0006] The application is as follows:

[0007] A passenger elevator with short-circuit protection includes an elevator car and a car top railing fixedly installed on the top of the elevator car. A control cabinet assembly is installed on the car top railing. The control cabinet assembly includes a cabinet body installed on the car top railing. The top and both sides of the cabinet body have first heat dissipation vents. A support frame is connected to the outer surface of the cabinet body. The top and both sides of the support frame have second heat dissipation vents, and filter screen bodies are installed in the second heat dissipation vents. The top of the cabinet body has a threaded groove, and the top of the support frame has a hand-tightening bolt that is threadedly connected to the threaded groove.

[0008] As a preferred technical solution of this application, the first heat dissipation port is connected to the second heat dissipation port to achieve heat dissipation.

[0009] As a preferred technical solution of this application, magnets are embedded on the inner walls of both sides of the support frame, and the magnets are attracted to the sides of the cabinet.

[0010] As a preferred technical solution of this application, the side of the magnet closest to the cabinet is on the same side as the inner wall of the support frame.

[0011] As a preferred technical solution of this application, the outer surface of the cabinet is provided with a sealing component, which is used to seal the first heat dissipation port after the support frame is removed.

[0012] As a preferred technical solution of this application, the sealing component is a protective frame, which is slidably fitted onto the outer surface of the cabinet and located on one side of the support frame.

[0013] As a preferred technical solution of this application, a handle is fixedly installed on the top of the protective frame, and the handle is used to assist the movement of the protective frame.

[0014] As a preferred technical solution of this application, two baffles are fixedly installed on the cabinet, and the two baffles are respectively located on the side of the protective frame and the support frame that are far apart from each other.

[0015] As a preferred technical solution of this application, the front of the cabinet is provided with a cabinet door.

[0016] As a preferred technical solution of this application, a cable routing port is provided on the back of the cabinet.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] To address the problem of time-consuming and labor-intensive process of disassembling and reassembling each filter screen during cleaning in existing technologies, this application proposes a solution by installing a support frame on the outside of the cabinet and mounting all filter screen bodies on the support frame. This achieves centralized management of the filter screens, allowing for one-time disassembly and reassembly of all filter screen bodies simply by removing and reassembling the support frame during cleaning.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] As described in the background section, while heat dissipation vents facilitate heat removal, they also become potential channels for dust and debris to enter the control cabinet. To prevent dust accumulation from affecting the performance and lifespan of electrical components, filters are usually installed at the heat dissipation vents to block dust. Although these filters are effective, they will gradually become clogged over time and need to be cleaned regularly to ensure their permeability. In the prior art, multiple filters are often installed separately, and each filter needs to be disassembled and reinstalled one by one for cleaning. This process is not only time-consuming and laborious, but also increases the difficulty of operation and maintenance costs.

[0028] To solve this technical problem, this utility model provides a passenger elevator with short-circuit protection function.

[0029] For details, please refer to Figures 1-4 Passenger elevators with short-circuit protection specifically include:

[0030] The elevator car 1 and the car top guardrail 101 fixedly installed on the top of the elevator car 1 are provided. The car top guardrail 101 is provided with a control cabinet assembly 2. The control cabinet assembly 2 includes a cabinet body 201 installed on the car top guardrail 101. The top and both sides of the cabinet body 201 are provided with first heat dissipation vents 202. The outer surface of the cabinet body 201 is connected to a support frame 204. The top and both sides of the support frame 204 are provided with second heat dissipation vents, and a filter screen body 205 is installed in the second heat dissipation vents. The top of the cabinet body 201 is provided with a threaded groove 203. The top of the support frame 204 is provided with a hand-tightening bolt 206 that is threadedly connected to the threaded groove 203.

[0031] The passenger elevator with short-circuit protection provided by this utility model achieves centralized management of the filters by setting a support frame 204 on the outside of the cabinet 201 and uniformly installing all filter bodies 205 on the support frame 204. In this way, when cleaning the filter bodies 205, it is only necessary to disassemble and assemble the support frame 204 to complete the disassembly and assembly of all filter bodies 205 at one time, which greatly simplifies the maintenance process and shortens the downtime.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] Example 1, please refer to Figures 1-4A passenger elevator with short-circuit protection includes an elevator car 1 and a car top guardrail 101 fixedly installed on the top of the elevator car 1. A control cabinet assembly 2 is installed on the car top guardrail 101. The control cabinet assembly 2 includes a cabinet body 201 installed on the car top guardrail 101. The top and both sides of the cabinet body 201 have first heat dissipation vents 202. A support frame 204 is connected to the outer surface of the cabinet body 201. The top and both sides of the support frame 204 have second heat dissipation vents, and filter screen bodies 205 are installed in the second heat dissipation vents. The top of the cabinet body 201 is provided with a threaded groove 203, and the top of the support frame 204 is provided with a hand-tightening bolt 206 that is threadedly connected to the threaded groove 203. The application proposes to install a support frame 204 on the outside of the cabinet 201 and uniformly install all filter screen bodies 205 on the support frame 204, thereby achieving centralized management of the filter screens. In this way, when cleaning the filter screen bodies 205, only the support frame 204 needs to be disassembled and reassembled to complete the disassembly and assembly of all filter screen bodies 205 at one time, which greatly simplifies the maintenance process and shortens downtime. The hand-tightening bolt 206 is threadedly connected to the support frame 204. After rotating the hand-tightening bolt 206 to separate the hand-tightening bolt 206 from the threaded groove 203, the support frame 204 can be lifted upward to remove it. If necessary, a handle can also be installed on the support frame 204 to facilitate the removal of the support frame 204.

[0036] To improve heat dissipation, existing radiators can also be installed inside the elevator car 1.

[0037] Furthermore, the first heat dissipation port 202 is connected to the second heat dissipation port to dissipate heat. Heat dissipation can reduce the possibility of heat accumulation causing short circuit faults in electrical components, thereby achieving short circuit protection.

[0038] Furthermore, such as Figure 3 and Figure 4 As shown, magnets 207 are embedded on the inner walls of both sides of the support frame 204. The magnets 207 are attracted to the side of the cabinet 201. The position of the magnets 207 is close to the bottom of the support frame 204. The magnets 207 can limit the bottom area of ​​the support frame 204 to promote the fit between the support frame 204 and the cabinet 201.

[0039] Furthermore, the side of magnet 207 closest to cabinet 201 is on the same side as the inner wall of support frame 204. This arrangement avoids magnet 207 protruding, which would cause an excessive gap between support frame 204 and cabinet 201, and also avoids magnet 207 being recessed, which would result in poor attraction between it and cabinet 201.

[0040] Example 2 further optimizes the passenger elevator with short-circuit protection function provided in Example 1, specifically, as follows: Figure 2 and Figure 4As shown, a sealing element is provided on the outer surface of the cabinet 201. The sealing element is used to seal the first heat dissipation port 202 after the support frame 204 is removed. Due to the poor air circulation in the elevator shaft, dust may enter the cabinet 201 through the first heat dissipation port 202 when cleaning the filter body 205 in the elevator shaft. This application seals the first heat dissipation port 202 with the sealing element, thereby reducing the possibility of dust entering the cabinet 201 through the first heat dissipation port 202 during the cleaning of the filter body 205.

[0041] Furthermore, such as Figure 2 As shown, the sealing component is a protective frame 209. The protective frame 209 is slidably sleeved on the outer surface of the cabinet 201. The protective frame 209 is located on one side of the support frame 204. The protective frame 209 is movable so that it can be moved to the first heat dissipation port 202 to seal the first heat dissipation port 202 after the support frame 204 is removed.

[0042] Furthermore, such as Figure 2 As shown, a handle 210 is fixedly installed on the top of the protective frame 209. The handle 210 is used to assist the movement of the protective frame 209, making it convenient for maintenance personnel to operate the protective frame 209.

[0043] Example 3 further optimizes the passenger elevator with short-circuit protection provided in Example 1 or 2, specifically, as follows: Figure 2 and Figure 3 As shown, two baffles 208 are fixedly installed on the cabinet 201. The two baffles 208 are located on the side of the protective frame 209 and the support frame 204 that are far apart from each other. The baffles 208 can limit the protective frame 209 and the support frame 204 to improve the stability of the connection between the support frame 204 and the cabinet 201.

[0044] Furthermore, such as Figure 2 As shown, cabinet 201 has a cabinet door 212 on the front.

[0045] Furthermore, a cable routing port is provided on the back of the cabinet 201. After the cable passes through the cable routing port, fireproof putty can be used to seal the gap between the cable routing port and the cable.

[0046] The passenger elevator with short-circuit protection provided by this utility model is used as follows:

[0047] Rotate the hand-tightening bolt 206 to separate it from the threaded groove 203, remove the support frame 204 from the cabinet 201, push the handle 210 to move the protective frame 209 toward the first heat dissipation vent 202 and cover it, clean the filter body 205, and after cleaning, push the handle 210 away from the first heat dissipation vent 202 to reset the protective frame 209, then put the support frame 204 back in place, tighten the hand-tightening bolt 206 to connect it with the threaded groove 203, and the magnet 207 can be attracted to the cabinet 201.

[0048] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0049] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
