Description

Technical Field

[0001] This utility model relates to an elevator shaft heating system, belonging to the field of elevator heating technology. Background Technology

[0002] With the increasing number of elevators being installed in older buildings, most of these elevator shafts are located outdoors without heating systems. Therefore, temperature control within the shafts becomes extremely important in cold regions. It is well known that in low-temperature environments, elevator components such as motors, inverters, and braking resistors may malfunction, potentially leading to equipment damage or operational failures. Furthermore, low temperatures can affect the elevator's braking performance and safety, increasing the failure rate. Therefore, maintaining the shaft within a suitable temperature range through heating devices and their proper layout is essential. Currently, temperature control often involves installing air conditioning systems in the machine room or shaft. This method is not only slow to heat up, but also noisy, provides heating only to a single area, and is expensive. Utility Model Content

[0003] The purpose of this invention is to provide an elevator shaft heating system to overcome the shortcomings of the existing technology.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an elevator shaft heating system, comprising...

[0005] Elevator shaft body;

[0006] Heating devices, a plurality of which are arranged longitudinally at intervals within the elevator shaft body, and the plurality of heating devices are connected in parallel;

[0007] A temperature sensor is installed inside the elevator shaft body and electrically connected to the heating device. The temperature sensor is used to monitor the temperature inside the elevator shaft body in real time.

[0008] The controller is installed inside the elevator shaft body, and is electrically connected to both the heating device and the temperature sensor. The temperature sensor interacts with the controller, and the controller controls the on / off state of the heating device's circuit to adjust the temperature of the heating device.

[0009] Preferably, a control cabinet is installed inside the elevator shaft body, and the controller is fixed on the control cabinet.

[0010] Preferably, the plurality of heating devices are connected in parallel by cables, and the controller is electrically connected to the heating devices and temperature sensors by cables.

[0011] Preferably, the elevator shaft body has multiple crossbeams and sills, and the heating device is fixedly installed below the crossbeams or sills.

[0012] Preferably, the heating device is a finned heater.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0014] 1. The elevator shaft heating system of this utility model, by setting multiple heating devices at intervals in the elevator shaft body, not only heats up quickly and evenly, but also takes into account the entire shaft. At the same time, the heating devices are connected in parallel, so the failure of a single heating device will not affect the normal operation of other heating devices, which greatly improves the reliability of the system. Even if some heating devices fail, the system can still maintain a certain heating capacity to ensure that the temperature of the elevator shaft does not fluctuate significantly.

[0015] 2. The temperature sensor monitors the temperature inside the elevator shaft in real time and feeds the data back to the controller. The controller precisely controls the working status of the heating device according to the preset temperature range, realizing the automatic and precise adjustment of the elevator shaft temperature. Compared with the traditional manual control or simple timed heating method, it can meet the temperature requirements of the elevator shaft under different environmental conditions more timely and accurately, avoid damage to elevator components due to excessively low temperature, and ensure the normal operation of the elevator.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] As attached Figure 1-3 As shown, the elevator shaft heating system of this utility model includes an elevator shaft body 1, a heating device 2, a temperature sensor 3, and a controller 4.

[0023] Multiple heating devices 2 are provided, and the multiple heating devices 2 are arranged longitudinally and spaced apart in the elevator shaft body 1. Specifically, the elevator shaft body 1 has multiple crossbeams 11 and sills (not shown in the figure). The heating devices 2 are fixedly installed below the crossbeams 11 or sills. The crossbeams 11 and sills are used as support structures, making full use of the existing structure in the shaft. The installation process is simple, does not occupy shaft space, and ensures that the heating devices 2 are installed firmly and do not affect the normal operation of the elevator.

[0024] It should be noted that the sill is a commonly used component in this field. As an important supporting component for the elevator's landing door and car door, it is usually installed on the crossbeam 11.

[0025] In this embodiment, the heating device 2 adopts a finned heater, which has the characteristics of large heat dissipation area and high heating efficiency. In addition, regarding the spacing arrangement of the heating device 2, it can be set in every layer or every other layer. Of course, the spacing distance can also be adjusted according to the actual situation to meet the requirements of uniform heating.

[0026] Multiple heating devices 2 are connected in parallel. In this embodiment, multiple heating devices 2 are connected in parallel using cables 6. This connection method allows each heating device 2 to work independently. Even if one heating device 2 fails, the other heating devices 2 can still operate normally, thus improving the reliability of the system.

[0027] Temperature sensor 3 is installed inside elevator shaft body 1 and is electrically connected to heating device 2. Heating device 2 and temperature sensor 3 are electrically connected by cable 6. Temperature sensor 3 is used to monitor the temperature inside elevator shaft body 1 in real time.

[0028] The controller 4 is installed inside the elevator shaft body 1. Specifically, the elevator shaft body 1 is equipped with a control cabinet 5, and the controller 4 is fixed on the control cabinet 5. The controller 4 is electrically connected to the heating device 2 and the temperature sensor 3. The controller 4 is electrically connected to the heating device 2 and the temperature sensor 3 by a cable 6. The temperature sensor 3 interacts with the controller 4. The controller 4 controls the circuit switching of the heating device 2 to adjust the temperature of the heating device 2.

[0029] As attached Figure 3As shown, during operation, the temperature sensor 3 continuously monitors the temperature inside the elevator shaft body 1 in real time and transmits the monitored temperature data to the controller 4 in real time. The controller 4 has a preset appropriate temperature range. When the received temperature data is lower than the preset lower limit, the controller 4 controls the circuit of the heating device 2 to be turned on, and multiple parallel heating devices 2 start working simultaneously to heat the elevator shaft. As the temperature inside the shaft gradually rises, when the temperature monitored by the temperature sensor 3 reaches the preset upper limit, the controller 4 controls the circuit of the heating device 2 to be turned off and stop heating. In this way, the automatic adjustment and precise control of the temperature inside the elevator shaft is achieved.

[0030] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model; all technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of protection of this utility model.
