Description

Technical Field

[0001] This invention relates to the field of cable installation technology, and in particular to a device for stabilizing the operation of elevator traveling cables. Background Technology

[0002] like Figure 1-2 As shown, the traveling cable is the communication cable between the elevator car and the control system. Its two ends are suspended on the shaft and the bottom of the elevator car 6, respectively, and it moves back and forth with the elevator. Generally, the traveling cable is designed as a single cable (hereinafter referred to as the main cable 2) according to the basic requirements of the elevator car 6. In recent years, with the increasing diversification of elevator market demands, such as the configuration of air conditioning, computer monitoring screens, real-time broadcasting systems, etc., an additional traveling cable (hereinafter referred to as the external cable 3) will be added. The external cable 3 is generally lighter and less stable in operation. As the elevator runs at high speed, it will deflect, twist, and swing. Because the free suspension bending diameters of the main cable 2 and the external cable 3 are different, the deflection, twisting, and swinging of the external cable 3 will be aggravated. It is easy to collide with the shaft wall, shaft components, and other elevator components, resulting in damage to the main cable 2 or elevator components, and a series of elevator operation safety problems such as elevator malfunction and entrapment. If the problem caused by the unstable operation of the external cable is to be solved by increasing the weight of the external cable, it will not only significantly increase the cost of the cable, but also involve a series of inefficient and inconvenient problems such as installation and modification.

[0003] Furthermore, the inconsistent free bending diameters and elongation rates of the main cable 2 and the external cable 3 will cause their operating trajectories to be inconsistent. Other components in the elevator shaft need to be designed with a large space allowance to avoid the main cable 2 and the external cable 3, which will increase the elevator design cost and complexity. If the external cable 3 is installed in a bundled manner with the main cable 2 to solve the above problems, then during elevator operation, issues such as... Figure 3 The image shows a situation where the cable is bulging or twisted, resulting in broken strands or even broken cores. Summary of the Invention

[0004] The purpose of this invention is to provide a device for stabilizing the operation of the traveling cable, so as to solve the problems in the prior art where the external cable is unstable and prone to deflection, twisting, swinging and collision during the high-speed operation of the elevator, which leads to damage to elevator components.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The traveling cable stabilization device includes several stabilization units, each stabilization unit comprising:

[0007] A main cable clamping connection assembly installed on the main cable operating section includes a main cable clamping assembly and a main cable connection assembly disposed on the main cable clamping assembly;

[0008] An external cable clamping connection assembly installed on the external cable running section includes an external cable clamping assembly and an external cable connection assembly disposed on the external cable clamping assembly;

[0009] The elastic telescopic component is rotatably connected at one end to the main cable connection component and at the other end to the external cable connection component. The elastic telescopic component rotates and extends in the vertical plane as the main cable and the external cable move.

[0010] Furthermore, both the main cable connection assembly and the external cable connection assembly include a pair of horizontally opposite connecting ears and a connecting shaft horizontally connected to the pair of connecting ears, and the two ends of the elastic telescopic assembly are respectively rotatably connected to the connecting shaft of the main cable connection assembly and the connecting shaft of the external cable connection assembly.

[0011] Furthermore, both the main cable connection assembly and the external cable connection assembly include a pair of horizontally opposite connecting ears, and the two ends of the elastic telescopic assembly are rotatably connected to the pair of connecting ears of the main cable connection assembly and the pair of connecting ears of the external cable connection assembly respectively through bearings.

[0012] Furthermore, the elastic telescopic component includes a sleeve assembly and an elastic element. One end of the sleeve assembly is rotatably connected to the main cable connection assembly, and the other end is rotatably connected to the external cable connection assembly. The elastic element is located inside the sleeve assembly, with one end connected to one end of the sleeve assembly and the other end connected to the other end of the sleeve assembly.

[0013] Furthermore, the sleeve assembly includes an inner sleeve and an outer sleeve. One end of the inner sleeve is rotatably connected to the main cable connection assembly, and one end of the outer sleeve is rotatably connected to the external cable connection assembly. The other end of the inner sleeve is slidably sleeved inside the other end of the outer sleeve.

[0014] Furthermore, both the main cable clamping assembly and the external cable clamping assembly include a pair of clamping half-frames arranged opposite each other. The pair of clamping half-frames are connected by connectors to form a complete clamping frame that clamps and fixes the main cable / external cable to the outside. The main cable connection assembly / external cable connection assembly is provided on one of the clamping half-frames between the main cable and the external cable in the pair of clamping half-frames arranged on the main cable / external cable.

[0015] Furthermore, the clamping surface of any one of the clamping half frames in the pair of clamping half frames is provided with a piercing buckle, which passes through the sheath buckle of the main cable / external cable and is fixed to the tension element of the main cable / external cable.

[0016] Furthermore, the sheaths of the corresponding pair of clamping half-frames and wire ropes are partially peeled off, and a pair of clamping bolts are installed on both sides of the piercing buckle on the clamping frame.

[0017] Furthermore, the pair of clamping half-frames are components made of metal.

[0018] Furthermore, the elastic telescopic component rotates within a range between vertically upward and vertically downward, and the external cable is installed outside the main cable.

[0019] The advantages of this invention are:

[0020] 1. The traveling cable stabilization device can restrain / limit the deflection, twisting, and swinging of the external cable, improve the stability of the traveling cable, reduce the failure rate of elevator operation, and improve the phenomenon of people being trapped in elevator malfunctions.

[0021] 2. When the accompanying cable adopts the method of external cable, there is no need to increase the weight of the external cable module, and the weight of the main cable can even be reduced, which significantly reduces the cable cost. At the same time, it can improve the efficiency of installation and modification and improve the convenience of the project.

[0022] 3. When the main cable and the external cable are installed in a stacked manner, the distance between the bottom of the "U" shape of the two cables should always be kept in a free state to avoid the cable being pulled when the traveling cable stabilization device moves to the bottom of the "U" shape of the cable; to eliminate the situation where the cable core is broken or even broken due to cable bulging or twisting during elevator operation.

Detailed Implementation

[0033] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0034] like Figure 4-7 As shown, the traveling cable stabilization device includes several stabilization units 1, each stabilization unit 1 comprising:

[0035] The main cable clamping connection assembly 11 installed on the main cable 2 operating section includes a main cable clamping assembly 111 and a main cable connection assembly 112 disposed on the main cable clamping assembly 111;

[0036] The external cable clamping and connecting assembly 12 installed on the running section of the external cable 3 includes an external cable clamping assembly 121 and an external cable connecting assembly 122 disposed on the external cable clamping assembly 121;

[0037] The elastic telescopic component 13 is rotatably connected at one end to the main cable connection component 112 and at the other end to the external cable connection component 122. The elastic telescopic component 13 rotates and extends in the vertical plane as the main cable 2 and the external cable 3 move.

[0038] When the elevator car is running, the running trajectories of the main cable 2 and the external cable 3 are inconsistent. The distance and orientation between the main cable clamping connection component 11 and the external cable clamping connection component 12 in the same stabilizing unit 1 will change. The elastic telescopic component 13 will adaptably rotate and extend in the vertical plane, restricting rotation and extension in the left and right directions, preventing the external cable 3 from deflecting, twisting, or swinging, and effectively preventing other elevator components from being damaged. The main cable 2 and the external cable 3 are both in a free state at the "U"-shaped bend, solving the problem of cable bulging and twisting during elevator operation and improving the safety factor.

[0039] In some embodiments, both the main cable connection assembly 112 and the external cable connection assembly 122 include a pair of horizontally opposite connecting ears and a connecting shaft horizontally connected to the pair of connecting ears. The two ends of the elastic telescopic assembly 13 are rotatably connected to the connecting shafts of the main cable connection assembly 112 and the external cable connection assembly 122, respectively. This allows the elastic telescopic assembly 13 to adaptively rotate in a vertical plane.

[0040] In some embodiments, both the main cable connection assembly 112 and the external cable connection assembly 122 include a pair of horizontally opposite connecting ears. The two ends of the elastic telescopic assembly 13 are rotatably connected to the pair of connecting ears of the main cable connection assembly 112 and the pair of connecting ears of the external cable connection assembly 122 via bearings, respectively. This allows the elastic telescopic assembly 13 to adaptively rotate in a vertical plane.

[0041] In some embodiments, the elastic telescopic component 13 includes a sleeve component 131 and an elastic element 132. One end of the sleeve component 131 is rotatably connected to the main cable connection component 112, and the other end is rotatably connected to the external cable connection component 122. The elastic element 132 is located inside the sleeve component 131, with one end connected to one end of the sleeve component 131 and the other end connected to the other end of the sleeve component 131.

[0042] In some embodiments, the elastic element 132 may be a component made of spring, elastic rubber or other elastic material. When the elevator is running, if the main cable 2 and the external cable 3 have inconsistent running trajectories, the distance can be finely adjusted without having to deal with the situation where the cable binding method produces knots or protrusions.

[0043] In some embodiments, the sleeve assembly 131 includes an inner sleeve and an outer sleeve. One end of the inner sleeve is rotatably connected to the main cable connection assembly 112, and one end of the outer sleeve is rotatably connected to the external cable connection assembly 122. The other end of the inner sleeve is slidably sleeved inside the other end of the outer sleeve.

[0044] In some embodiments, both the main cable clamping assembly 111 and the external cable clamping assembly 121 include a pair of clamping half-frames 8 arranged opposite each other. The pair of clamping half-frames 8 are connected by connectors such as buckles, bolts or other means to form a complete clamping frame that is clamped and fixed to the outside of the main cable 2 / external cable 3.

[0045] In some embodiments, the main cable connection assembly 112 / external cable connection assembly 122 is provided on one of the two clamping half-frames 8 located between the main cable 2 and the external cable 3.

[0046] The running trajectories of the external cable 3 and the main cable 2 are not completely consistent; during the elevator's up and down movement, the sheaths of the two cables will rub against each other and generate static electricity, which can be easily transmitted from the cable sheath 7 to the control system, causing damage to the electronic components inside the control system; if the cable has a shielding layer, the interference noise signals isolated by the shielding layer cannot be effectively released to the outside through the metal medium, the shielding effect will be greatly reduced, and heat will easily accumulate, causing the cable performance to deteriorate.

[0047] Elevator height increase, such as Figure 6 As shown, traveling cables usually require the addition of tension-bearing elements such as steel wire rope 4. The steel wire rope 4 is incorporated into the cable and wrapped by the cable sheath 7. As the elevator lifting height increases, the weight of the cable also increases. This will cause insufficient adhesion between the cable sheath 7 and the steel wire rope 4, resulting in slippage and loss of the tension-bearing effect of the steel wire rope 4. As a result, the traveling cable may also experience broken strands or even broken cores.

[0048] To address the adverse effects of static electricity, interference signals, and heat, as well as the insufficient tensile strength of the wire rope 4, in some embodiments, such as... Figure 7 As shown, the clamping surface of either of the pair of clamping half-frames 8 is provided with a piercing buckle 5, which passes through the sheath buckle of the main cable / external cable and is fixed to the steel wire rope 4 of the main cable / external cable. The pair of clamping half-frames 8 are components made of metal.

[0049] The main cable 2 and external cable 3 generate static electricity due to friction during elevator operation. The interference noise and heat generated by the shielded cable are effectively released through the following paths: the metal clamping frame of the running stabilization device, the piercing buckle, the tension element (steel wire rope) in the traveling cable, the hanging frame of the car bottom metal structure, and the entire car frame / car.

[0050] The clamping surface of the clamping frame makes full contact with and clamps the cable, increasing the adhesion between the wire rope 4 and the sheath 7. The piercing buckle 5 pierces the sheath 7 and clamps the wire rope, which can also play a fixed-point fixing role, greatly enhancing the adhesion.

[0051] In some embodiments, such as Figure 8 As shown, a portion of the sheath 7 corresponding to a pair of clamping half-frames 8 and the wire rope is peeled off. A pair of clamping bolts 9 are installed on both sides of the piercing buckle on the clamping frame to enhance the effect of the piercing buckle clamping the wire rope 4.

[0052] In some embodiments, the elastic telescopic component 13 rotates within a range between vertically upward and vertically downward, so that the distance between the bottom of the "U" shape of the two cables is always kept in a free state, avoiding the cable pulling when the traveling cable stabilizing device runs to the bottom of the "U" shape of the cable; eliminating the situation where the cable core breaks due to cable bulging or twisting during elevator operation.

[0053] Typically, the external cable 3 has a large elongation rate, resulting in a large "U-shaped" gap between it and the main cable. In some embodiments, the external cable 3 is installed outside the main cable 2 and is attached to the main cable by a running stabilizing device to provide some support.

[0054] The technical solutions provided by the embodiments of the present invention have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of the present invention. The descriptions of the embodiments above are only for helping to understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
