Description

Technical Field

[0001] This utility model relates to the field of cable anti-sway technology, and in particular to an elevator traveling cable anti-sway device. Background Technology

[0002] As is well known, the elevator traveling cable is the link between the car and the control cabinet for transmitting information and instructions, and it is an elevator component that moves up and down at the same speed as the elevator. The elevator traveling cable anti-sway device is an important component of the elevator system. Its main function is to prevent the cable from swaying due to factors such as wind force and inertia during elevator operation, thereby protecting the cable from damage and ensuring the safe and stable operation of the elevator.

[0003] The existing traveling cable is subject to random lateral swaying under wind load, which can easily cause the traveling cable to scrape against the guide rail support and break, thus affecting the normal operation of the elevator.

[0004] An existing patent (publication number: CN203593491U) discloses an anti-sway device for elevator traveling cables, which includes a car assembly connected to a car control cabinet and moving synchronously up and down along the car guide rails with the car assembly. The key feature is that the traveling cable is placed in a cable groove and connected to a cable guide bracket mounted on the car assembly. By placing the traveling cable in a cable groove parallel to the elevator car guide rails, it provides a guiding space for the vertical movement of the traveling cable, effectively solving the problem of lateral sway of the traveling cable, thereby avoiding the risk of the traveling cable breaking during movement and ensuring stable and reliable elevator operation.

[0005] To address the aforementioned issues, existing patents provide solutions that, by placing the traveling cable in a cable trough parallel to the elevator car guide rails, offer a guiding space for the vertical movement of the traveling cable. However, since the cable moves up and down with the elevator, it cannot be guaranteed that the cable will accurately enter the cable trough during the movement, thus failing to effectively prevent cable skewing. Summary of the Invention

[0006] The purpose of this utility model is to provide an elevator traveling cable anti-sway device, which can play a guiding role. With the cooperation of the guide groove, it prevents the limiting component from shaking and pressing the elevator cable, so that the elevator cable is pressed into the inside of the device shell, thereby ensuring that the elevator cable can enter the protective mechanism normally, playing a good anti-sway role, effectively reducing the situation where the elevator cable cannot enter the protective mechanism, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an elevator traveling cable anti-sway device, comprising a device housing, an elevator cable being disposed inside the device housing, a limiting mechanism disposed inside the device housing on one side of the elevator cable, and a fixing mechanism for fixing the device being disposed on the outer wall of the device housing.

[0008] The limiting mechanism includes a limiting member, which is placed inside the device housing. The outer surface of the limiting member is covered with a protective rubber sleeve. Both ends of the limiting member are fitted with fixed bearings, and the outer wall of the fixed bearings is fixed with a slider.

[0009] Preferably, a counterweight is fixed to the upper surface of the slider, and a limiting plate fixed to the outer shell of the device is slidably connected to one side of the slider.

[0010] Preferably, a fixing plate is installed at one end of the slider, and a fixing screw that is threadedly connected to the slider is installed on the side wall of the fixing plate.

[0011] Preferably, guide rollers are installed on both sides of the slider, and the outer surface of the guide rollers is slidably connected to guide grooves formed in the inner wall of the limiting plate.

[0012] Preferably, the slider has two mounting holes inside, and the guide roller is rotatably connected to the mounting holes via bearings.

[0013] Preferably, one end of the elevator cable is fitted with a mounting plate.

[0014] Preferably, the fixing mechanism includes four connecting blocks, all of which are fixed to the outer wall of the device housing, and each of the four connecting blocks is fitted with a fixing bolt.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The limiting mechanism can play a guiding role. With the cooperation of the guide groove, it can prevent the limiting part from shaking and pressing the elevator cable, so that the elevator cable is pressed into the inside of the device shell. This ensures that the elevator cable can enter the protective mechanism normally, which plays a good role in preventing swaying and effectively reduces the situation where the elevator cable cannot enter the protective mechanism.

[0017] 2. By using the fixed mechanism and the fixing bolts on the connecting block, the outer shell of the device is placed in the vertical position of the shaft, which facilitates the fixing of the device. Attached Figure Description

[0025] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 An elevator traveling cable anti-sway device includes a device housing 1, an elevator cable 2 is installed inside the device housing 1, a limiting mechanism installed inside the device housing 1 is provided on one side of the elevator cable 2, and a fixing mechanism for fixing the device is provided on the outer wall of the device housing 1.

[0028] The limiting mechanism includes a limiting component 3, which is installed inside the outer shell 1 of the device. A protective rubber sleeve 31 is fitted on the outer surface of the limiting component 3. Fixed bearings 32 are fitted on both ends of the limiting component 3. A slider 33 is fixed on the outer wall of the fixed bearing 32. A counterweight 34 is fixed on the upper surface of the slider 33. A limiting plate 35 fixed on the outer shell 1 is slidably connected to one side of the slider 33. A fixing plate 36 is installed on one end of the slider 33. A fixing screw 37 threadedly connected to the slider 33 is installed on the side wall of the fixing plate 36. Guide rollers 38 are installed on both sides of the slider 33. A guide groove 39 opened in the inner wall of the limiting plate 35 is slidably connected to the outer surface of the guide roller 38.

[0029] By adopting the above technical solution, before using the elevator traveling cable anti-sway device, one end of the elevator cable 2 is connected to the receiving end inside the elevator car, and the other end of the elevator cable 2 is connected to the data transmitting end in the machine room. When the elevator car rises, it will synchronously drive the elevator cable 2 to move, causing the elevator cable 2 to move out of the device housing 1. At this time, the elevator cable 2 will drive the limiting member 3 to slide vertically on the limiting plate 35, and the fixed bearing 32 can ensure that the limiting member 3 can rotate, thereby ensuring the smooth movement of the elevator cable 2. The protective rubber sleeve 31 on the outer surface of the limiting member 3 plays a protective role, reducing the wear on the elevator cable 2. When the elevator descends... At the same time, the elevator cable 2 descends synchronously, and under the action of the counterweight 34, it will press the slider 33 to move vertically. The guide roller 38 set on the slider 33 can play a guiding role. With the cooperation of the guide groove 39, it can prevent the limiting member 3 from shaking. When the limiting member 3 descends, it will press the elevator cable 2, so that the elevator cable 2 is pressed into the inside of the device housing 1, thereby ensuring that the elevator cable 2 can enter the protective mechanism normally, playing a good anti-sway role and effectively reducing the situation where the elevator cable 2 cannot enter the protective mechanism. By unscrewing the fixing screw 37 on the fixing plate 36, the guide roller 38 can be disassembled with the cooperation of the mounting hole 4, which is convenient for maintenance and replacement.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the slider 33 has two mounting holes 4 inside. The guide roller 38 is rotatably connected to the mounting holes 4 through bearings. One end of the elevator cable 2 is equipped with a mounting plate 5. The fixing mechanism includes connecting blocks 6. There are four connecting blocks 6. All four connecting blocks 6 are fixed to the outer wall of the device housing 1. Fixing bolts 61 are installed inside the four connecting blocks 6.

[0031] By adopting the above technical solution, the elevator cable 2 at one end of the elevator car is limited by the mounting plate 5. The mounting plate 5 can be fixed to the outer wall of the elevator car with bolts, thereby limiting the elevator cable 2 and reducing the possibility of it falling off. The device housing 1 is placed in the vertical position of the shaft by the fixing bolts 61 set in the connecting block 6, and the elevator cable 2 is placed inside the device housing 1.

[0032] Working principle: When the elevator car rises, it synchronously drives the elevator cable 2 to move, causing the elevator cable 2 to move out of the device housing 1. The elevator cable 2 will drive the limiting member 3 to slide vertically on the limiting plate 35. The fixed bearing 32 ensures that the limiting member 3 can rotate. The protective rubber sleeve 31 on the outer surface of the limiting member 3 plays a protective role, reducing the wear of the elevator cable 2. When the elevator descends, the elevator cable 2 descends synchronously. Under the action of the counterweight 34, it will press the slider 33 to move vertically. The guide roller 38 set on the slider 33 plays a guiding role. When the limiting member 3 descends, it will press the elevator cable 2, and the elevator cable 2 will be pressed into the inside of the device housing 1, thus ensuring that the elevator cable 2 can enter the protective mechanism normally. By unscrewing the fixing screw 37 on the fixing plate 36, the guide roller 38 can be disassembled with the cooperation of the mounting hole 4.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
