[0037] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.

[0038] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Furthermore, when an element is considered to be "transmission-connected" to another element, the two can achieve power transmission, and its specific implementation method can be implemented using the existing technology, which will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only implementation method.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0040] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0041] Please refer to the attached Figure 1 -Attached Fig.15 The utility model embodiment proposes a rainproof lift, which includes a chassis and a supporting mechanism, a lifting drive mechanism and a wire-reeling mechanism installed inside the chassis; the supporting mechanism is used to install the lifting drive mechanism and the wire-reeling mechanism, and the lifting drive mechanism is used to control the operation of the wire-reeling mechanism; the wire-reeling mechanism includes a wire reel 1, which is rotatably installed in the chassis by rotating a main shaft 2, and a wire rope 3 is wound on the wire reel 1; the chassis is surrounded by an upper cover plate 4, a lower cover plate 5, a left side plate 6, a right side plate 7, a front panel 8 and a rear panel 9, and the chassis also includes a rainproof cover 10, which covers the upper cover plate 4 and has a surrounding plate 11 extending downward around the rainproof cover 10.

[0042] Specifically, the winding drum 1 includes two upper and lower disks, and the wire rope 3 is superimposed and wound in the winding space formed by the upper and lower disks.

[0043] It is understandable that the support mechanism is responsible for fixing and supporting the lifting drive mechanism and the retractable wire mechanism so that the lifting drive mechanism and the retractable wire mechanism can operate smoothly. The lifting drive mechanism is responsible for controlling the operation of the retractable wire mechanism to realize the retractable action of the wire rope 3. The chassis is surrounded by an upper cover plate 4, a lower cover plate 5, a left side plate 6, a right side plate 7, a front panel 8 and a rear panel 9, and is fixed by screws 32 to form a closed space to protect the internal components from the external environment. The utility model covers the upper cover plate 4 with a rainproof cover 10, and extends downward to form a panel 11. The rainproof cover 10 can wrap the connection interface between the upper cover plate 4 and the left side plate 6, the right side plate 7, the front panel 8, and the rear panel 9, thereby improving the rainproof effect of the chassis.

[0044] In a feasible scheme of the present embodiment, a wire passing hole 12 is provided on the lower cover plate 5, and a guide wheel assembly 13 is installed on one side of the wire passing hole 12 inside the chassis. One end of the wire rope 3 passes through the guide wheel assembly 13 and then comes out from the wire passing hole 12 of the lower cover plate 5, and is used to connect with an external device, such as an LED lamp.

[0045] It is understood that the guide wheel assembly 13 is used to reduce the loss and friction of the wire rope 3, so that the winding drum 1 runs more smoothly. Specifically, the guide wheel assembly 13 can be composed of a series of rollers or guide rails, which guide the wire rope 3 to move along a predetermined path, reduce the friction and distortion of the wire rope 3 during the movement, and avoid the wire rope 3 from being tangled or damaged. In addition, the guide wheel assembly 13 can also help evenly distribute the tension on the wire rope 3 to ensure the smooth operation of the elevator.

[0046] In this embodiment, the supporting mechanism includes a main bridge plate 14 parallel to the front panel 8 and the rear panel 9, the top end of the main bridge plate 14 is fixedly connected to the upper cover plate 4 by screws 32, and the bottom end of the main bridge plate 14 is fixedly connected to the lower cover plate 5 by screws 32. The main bridge plate 14 divides the interior of the chassis into two spaces, and the cable reel 1 is located between the front panel 8 and the main bridge plate 14. One end of the rotating main shaft 2 is installed on the front panel 8 through a bearing, and the other end of the rotating main shaft 2 is installed on the main bridge plate 14 through a bearing.

[0047] It can be understood that the main bridge plate 14 not only plays a role of physical support, but also plays a role of space separation, dividing the internal space of the chassis into two parts, which is conducive to the layout and management of internal components. Its top and bottom ends are fixedly connected to the upper cover plate 4 and the lower cover plate 5 respectively, and the structural stability of the entire chassis is also enhanced.

[0048] In a preferred scheme of the present embodiment, the supporting mechanism further includes a plurality of groups of wire protection plates 15 installed on the main bridge frame plate 14 and arranged around the cable reel 1, that is, the cable reel 1 is located in a space area enclosed by a plurality of groups of wire protection plates 15, and includes a plurality of balancing support columns 16 located on the left and right sides of the cable reel 1, one end of the balancing support column 16 is fixedly connected to the main bridge frame plate 14 by a screw 32, and the other end of the balancing support column 16 is fixedly connected to the front panel 8 by a screw 32.

[0049] It is understandable that the wire guard plate 15 is mainly used to prevent the wire 3 from being exposed and causing machine failure when the chassis is tilted during transportation. The force generated when the disc is running will cause the disc to rotate out of parallelism. At this time, the balance support column 16 can play a role in correcting the level of the disc.

[0050] In this embodiment, the support mechanism also includes four shell fixing connecting rods 17 located at the four corners inside the chassis, the shell fixing connecting rods 17 pass through the main bridge frame plate 14, one end of the shell fixing connecting rod 17 is fixedly connected to the front panel 8 by a screw 32, and the other end of the shell fixing connecting rod 17 is fixedly connected to the rear panel 9 by a screw 32. A plurality of load-bearing reinforcement connecting rods 18 are also arranged inside the chassis, the load-bearing reinforcement connecting rods 18 pass through the main bridge frame plate 14, one end of the load-bearing reinforcement connecting rod 18 is fixedly connected to the front panel 8 by a screw 32, and the other end of the load-bearing reinforcement connecting rod 18 is fixedly connected to the rear panel 9 by a screw 32.

[0051] It is understandable that the four outer shell fixing connecting rods 17 are used to ensure the overall structural strength of the chassis and prevent the chassis from being deformed due to external forces. The load-bearing reinforcing connecting rods 18 also run through the main bridge plate 14, but their main purpose is to enhance the structural strength of the chassis main bridge plate 14 when carrying heavy objects.

[0052] In this embodiment, the lifting drive mechanism includes a power supply module 19, a lifting control main board 20, a motor 21 and a motor driver 22 installed on the main bridge frame plate 14, and the power supply module 19, the lifting control main board 20, the motor 21 and the motor driver 22 are located between the rear panel 9 and the main bridge frame plate 14, the power supply module 19 is electrically connected to the lifting control main board 20, the motor driver 22 is electrically connected to the lifting control main board 20, the motor 21 is electrically connected to the motor driver 22, and the output shaft of the motor 21 is connected to the rotating main shaft 2 through a transmission assembly to drive the rotating main shaft 2 to rotate.

[0053] Specifically, the power supply module 19 is responsible for providing stable power to the lifting control mainboard 20, the motor driver 22 and other electrical components to ensure that each component can work normally. The lifting control mainboard 20 is responsible for receiving operation instructions, processing data, and sending control signals to the motor driver 22 to accurately control the start, stop and speed adjustment of the motor 21 to achieve smooth operation of the elevator. The transmission component can be implemented by a gear transmission module, which includes gears and transmission belts. The output shaft of the motor 21 drives the rotating main shaft 2 to rotate through the cooperation of the gears and the transmission belt.

[0054] In a feasible scheme of the present embodiment, the lifting drive mechanism also includes an electromagnet assembly 23 and a brake pad, the electromagnet assembly 23 is installed on the main bridge frame plate 14 and is electrically connected to the lifting control main board 20, the brake pad is arranged on the side of the cable reel 1, the electromagnet assembly 23 is used to stop the rotation of the cable reel 1 by extending the iron core to resist the brake pad when the lifting control main board 20 detects that the cable reel 1 rotates too fast; an electromagnet reinforcement support 24 is also arranged next to the electromagnet assembly 23, one end of the electromagnet reinforcement support 24 is fixedly connected to the main bridge frame plate 14 by a screw 32, and the other end of the electromagnet reinforcement support 24 is fixedly connected to the rear panel 9 by a screw 32.

[0055] It is understandable that when the elevator is in normal lifting operation, the iron core of the electromagnet assembly 23 is in a retracted state. When the lifting control mainboard 20 detects that the lift is falling too fast or the power is temporarily cut off, the iron core is ejected by the spring and engages with the groove of the brake pad to act as a brake, thereby preventing safety accidents caused by loss of control. The electromagnet reinforcement support 24 is used to prevent the impact force when the iron core on the electromagnet assembly 23 engages with the brake pad to cause the main bridge frame plate 14 to deform.

[0056] In this embodiment, the lifting drive mechanism further includes a touch screen 25, which is electrically connected to the lifting control mainboard 20. A transparent touch screen protection plate 26 is provided on the surface of the touch screen 25. An opening is provided on the chassis to accommodate the transparent touch screen protection plate 26. The gap between the transparent touch screen protection plate 26 and the chassis opening is sealed with a waterproof adhesive coating. A temperature and humidity sensor 28 is installed near the touch screen 25.

[0057] It can be understood that the touch display screen 25 is used to provide a human-machine operating interface for setting parameters of the elevator. The transparent touch screen protection plate 26 is a protective component designed specifically for touch screen devices. Users can perform touch operations just like directly operating the screen without affecting the user experience. By using a waterproof glue coating to seal the gap between the transparent touch screen protection plate 26 and the chassis opening, it effectively prevents moisture, dust and other foreign substances from invading the interior of the chassis, thereby protecting the internal electronic components.

[0058] In a preferred scheme of the present embodiment, the lifting drive mechanism also includes a constant temperature fan heater 27 and a plurality of temperature and humidity sensors 28 installed on the main bridge plate 14, and the plurality of temperature and humidity sensors 28 are distributed near the power supply module 19, the lifting control main board 20, the motor driver 22 and the cable reel 1. An exhaust port 29 and a plurality of drainage holes 30 are provided on the lower cover plate 5. A waterproof fan 31 is installed at the bottom of the chassis above the exhaust port 29. The constant temperature fan heater 27, the waterproof fan 31 and the temperature and humidity sensor 28 are all electrically connected to the lifting control main board 20.

[0059] It can be understood that the utility model can quickly monitor the temperature and humidity conditions near key components and take quicker action by installing the temperature and humidity sensors 28 near the power module 19, the lifting control main board 20, the motor driver 22 and the cable reel 1.

[0060] Specifically, a temperature and humidity sensor 28 is installed on each of the left and right sides above the winding drum 1. When the elevator is used outdoors and encounters rain, the raindrops on the wire rope 3 will be brought into the elevator chassis as the wire rope 3 is wound. When the internal temperature and humidity sensor 28 recognizes a certain humidity, the lifting control mainboard 20 will control the wire rope 3 to be wound into the chassis and stop working. At this time, the machine is in a standby state to prevent the wire rope 3 from continuing to rise and fall and bringing more rain into the chassis. When any of the temperature and humidity sensors 28 recognizes that the humidity is too high, the lifting control mainboard 20 will control the constant temperature fan heater 27 to operate the heating function and blow the constant temperature hot air into the chassis to evaporate the moisture inside the chassis. At the same time, the waterproof fan 31 at the bottom of the chassis is operated to extract the evaporated moisture from the exhaust port 29, thereby ensuring a dry environment inside the chassis and not affecting the operation of the electronic components inside the chassis. The entire process is automatically controlled by the lifting control mainboard 20 according to the real-time data of the temperature and humidity sensor 28, without manual intervention, and is extremely intelligent. In addition, the running of the waterproof fan 31 is also used to enhance the heat dissipation effect inside the chassis.

[0061] In this embodiment, a waterproof rubber ring 33 is provided between all exposed screws 32 on the outer surface of the chassis and the outer surface of the chassis, which effectively prevents rainwater from penetrating into the interior of the chassis through the gaps between the screws 32. Preferably, the exposed screws 32 are rust-proof screws 32. The use of rust-proof screws 32 further enhances the corrosion resistance of the equipment and extends its service life.

[0062] Preferably, the outer surface of the chassis is also sprayed with a waterproof paint coating, and the surface of the electronic components inside the chassis is coated with a waterproof and moisture-proof coating to form a protective film, which can effectively isolate moisture even in a high-humidity environment, avoid short circuits, corrosion and other problems, and ensure the normal operation of the electronic components. A waterproof cable connector 34 and a safety ring 35 are installed on the top of the chassis. The waterproof cable connector 34 is preferably a stainless steel waterproof cable connector 34, which is installed on the top of the chassis and uses a sealing rubber ring and a nut to screw together with the electrical cable signal line to ensure the waterproof sealing of the cable connection and prevent moisture from invading the inside of the chassis along the cable.

[0063] In a preferred embodiment of this embodiment, Figure 3 , Figure 8-Figure 15 As shown, the edges of the lower cover plate 5, the left side plate 6, the right side plate 7, the front panel 8 and the rear panel 9 are arranged in a folded edge structure. Figure 8-Figure 15 As shown, the side edges and bottom edges of the front panel 8 and the rear panel 9 are respectively provided with raised extension edges 36, and the side edges of the left side panel 6, the right side panel 7 and the lower cover 5 are respectively provided with concave extension edges 37 matched with the raised extension edges 36, which are fixed by screws 32 after matching installation, and the other side edges of the left side panel 6 and the right side panel 7 are respectively provided with waterproof extension edges 38 extending downward, that is, the waterproof extension edges 38 protrude from the bottom surface of the chassis.

[0064] It can be understood that when used outdoors on rainy days, when the wind direction generated by high altitude and strong convective weather carries rainwater to the surface of the chassis, the cooperation of the raised extension edge 36 and the concave extension edge 37 can effectively block the rainwater from seeping in from the connecting gap, and the waterproof extension edge 38 prevents the rainwater from flowing downward from the surface of the chassis and seeping back into the chassis.

[0065] The utility model can improve the rainwater blocking effect through the folding edge structure, prevent rainwater from penetrating into the inside of the chassis from the connection between the lower cover plate 5, the left side plate 6, the right side plate 7, the front panel 8 and the rear panel 9, and form multiple folds and blocks through the folding edge, which significantly reduces the possibility of rainwater directly penetrating into the inside of the chassis, especially in a windy and rainy environment, and can effectively block the straight line penetration of rainwater along the edge of the plate. In addition, the folding edge structure not only improves the waterproof effect, but also increases the structural strength of the edge of the plate, reduces the deformation of the plate caused by external impact or long-term use, and further enhances the overall sealing performance of the chassis.

[0066] In this embodiment, the power module 19 , the lifting control main board 20 and the motor driver 22 are distributed on the main bridge plate 14 near the left and right edges.

[0067] It is understandable that when accessories such as the power module 19, the lifting control main board 20 and the motor driver 22 fail, the left side panel 6 and the right side panel 7 can be quickly removed to eliminate the problem and remove the accessories. Even after the hanging installation, the fault can be efficiently eliminated without disassembling the entire chassis.

[0068] When installing and disassembling the left side panel 6 and the right side panel 7, the fixing screws 32 can be directly unscrewed, and then the left side panel 6 and the right side panel 7 can be removed downward from the direction of the lower cover plate 5. When installing, move them upward from the direction of the lower cover plate 5 to the top for fixing. All installations are fixed based on the screw holes and screws 32 of the raised extension edges 36 on the front panel 8 and the rear panel 9 and the concave extension edges 37 on the left side panel 6 and the right side panel 7, which is convenient and quick to disassemble and assemble, and can reduce time costs during operation and maintenance, and improve work efficiency.

[0069] In addition, even if some rainwater seeps into the chassis, the drainage holes 30 provided on the lower cover plate 5 of the chassis can drain the rainwater in time, avoiding the accumulation of rainwater, preventing moisture and corrosion of internal components, and protecting the normal operation of electronic components.

[0070] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which are all protected by the utility model.
