Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and in particular to an installation device and an installation method for preventing a twisting of an elevator traction steel wire rope. Background Art

[0002] At present, when installing the traction wire rope, elevators on the market generally adopt an unguided installation method that relies on the traction wire rope's own weight to droop freely. Because the traction wire rope is a flexible component, this method cannot effectively control the movement trajectory of the traction wire rope, causing the traction wire rope to swing freely in the elevator shaft and easily get hooked on the hooking points in the shaft, affecting the installation efficiency and quality; an elevator often needs to use many traction wire ropes, and installing them by gravity drooping can easily cause the traction wire ropes to be entangled with each other, and it takes a long time to comb the traction wire rope, affecting the installation efficiency; in addition, this installation method keeps the traction wire rope in a free drooping state, which will cause the traction wire rope's loose strands to change in lay pitch, deformation of surface strength and external shape, and easy to cause twist displacement during operation, causing rotational stress in the rope, shortening the life of the traction wire rope and affecting the ride comfort of the elevator.

[0003] For example, the publication number "CN104176590A" discloses "an elevator with a guide rope translation positioning device", including a traction wire rope, a car, a traction wire rope reel, a motor, a gear box and a main frame. A flexible guide wheel is installed on the outside of the column of the car, and the car is installed in the main frame. A rope groove is opened on the outer periphery of the traction wire rope reel. One end of the traction wire rope is wound on the rope groove of the traction wire rope reel. It also includes a guide rope translation positioning device, which is arranged on the top of the elevator. The other end of the traction wire rope passes through the guide rope translation positioning device and is connected to the top of the car. However, in actual applications, this type of installation method can only install the traction wire rope from top to bottom, and the drooping state of the traction wire rope cannot be well controlled, and it is easy to get hooked and entangled. Summary of the invention

[0004] In view of the problem that the prior art mentioned in the background technology cannot ensure the installation stability of the traction wire rope, the present invention provides an anti-twisting installation device for the elevator traction wire rope, which can improve the installation stability of the traction wire rope inside the hoistway, ensure that the falling state of the traction wire rope is controllable, reduce the dressing steps, and improve the installation efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions.

[0006] An installation device for preventing the traction wire rope of an elevator from twisting includes a wire rope traction assembly arranged inside a hoistway, the wire rope traction assembly can move vertically along the hoistway, a wire rope feeding assembly is arranged at the bottom of the movement path of the wire rope traction assembly, the wire rope traction assembly can connect the traction wire rope on the wire rope feeding assembly and drive the traction wire rope to move from bottom to top. A wire rope traction assembly is arranged at the top of the hoistway, the wire rope traction assembly can hang down to the bottom of the hoistway and connect with the traction wire rope in the wire rope feeding assembly, the traction wire rope is driven to rise by the wire rope traction assembly, the traction wire rope is moved from bottom to top, the movement trajectory of the traction wire rope is unified, the control degree of the traction wire rope is improved, and the traction wire rope is prevented from swinging during the movement, causing it to be hooked with objects in the hoistway or entangled with the remaining traction wire ropes.

By arranging the guide rope, a lateral limiting effect can be provided for the wire rope traction assembly, and a guiding effect can be provided for the movement of the wire rope traction assembly, thereby ensuring the movement stability of the wire rope traction assembly and improving controllability.

[0008] One end of the guide rope is connected to the car at the bottom of the shaft, and the other end is connected to the top of the shaft. The two ends of the guide rope are respectively connected to the car and the top of the shaft, thereby fixing the two ends of the guide rope and keeping the guide rope in a vertical and taut state, thereby improving the guiding effect.

[0009] The wire rope traction assembly includes a traction body, and extension tubes are connected to both sides of the traction body, and a flexible rope is provided on the extension tube for sleeve-connecting the guide rope. Through the extension tube and the flexible rope, a larger gap can be set between the guide ropes on both sides, thereby avoiding interference and reducing the risk of entanglement of the traction wire rope.

[0010] The wire rope traction assembly is provided with a guide round tube and a guide clamping assembly, the traction wire rope passes through the guide clamping assembly to form a rope loop, the rope loop is sleeved on the guide round tube, and a rope blocking plate is movably connected to the guide round tube. The traction wire rope can form a rope loop structure through the guide round tube and the guide clamping assembly, and due to the round tube structure of the guide round tube, the traction wire rope will not bend, and it is ensured that an effective fixed connection effect can be provided for the traction wire rope.

[0011] The guide clamping assembly includes a guide clamping plate and a bottom rope clamp. After the traction wire rope passes through the bottom rope clamp and the guide clamping plate, it is bent back and connected to the bottom rope clamp again to form a rope loop. The rope loop structure of the traction wire rope is fixed by the bottom rope clamp, and the guide clamping plate can still fix the traction wire rope even after the bottom rope clamp is removed.

[0012] The wire rope traction assembly includes a transition traction unit, which is arranged at the top of the hoistway. A terminal traction unit is movably connected above the top of the hoistway.

By loosening the rope stop plate and the bottom rope clamp, the connection between the guide clamp plate is maintained, thereby ensuring the stability of the fixed position of the traction wire rope, and at the same time, the traction wire rope above the guide clamp plate can be flexibly moved to connect with the terminal traction unit, and the rope clamp can be reused at the end of the traction wire rope to form a small return structure to connect with the terminal traction unit, or the traction wire rope can be directly clamped by the terminal traction unit to continue the operation.

Since the movement path of the traction steel wire rope 6 is from bottom to top, the upper and lower ends of the traction steel wire rope 6 are respectively fixed during the movement of the traction steel wire rope 6. Therefore, the traction steel wire rope 6 can maintain a stable state during the installation process. Since the traction steel wire rope 6 is pulled from top to bottom, the movement trajectory of the traction steel wire rope 6 is unified, which improves the control degree of the traction steel wire rope 6, ensures the stability of the traction steel wire rope 6 during the movement, and avoids the traction steel wire rope 6 from swinging during the movement, causing it to be hooked with objects in the shaft 1 or entangled with the remaining traction steel wire ropes 6.

[0025] Embodiment 2: like Figure 1As shown, in this embodiment, a guide rope 5 is provided inside the hoistway 1, and the wire rope traction assembly 3 is slidably connected to the guide rope 5. One end of the guide rope 5 is connected to the car 2 located at the bottom of the hoistway 1, and the other end is connected to the top of the hoistway 1. By providing the guide rope 5, a lateral limiting effect can be provided for the wire rope traction assembly 3, and a guiding effect can be provided for the movement of the wire rope traction assembly 3, thereby ensuring the movement stability of the wire rope traction assembly 3 and improving controllability. By connecting the two ends of the guide rope 5 to the car 2 and the top of the hoistway 1 respectively, the two ends of the guide rope 5 are fixed, and the guide rope 5 can be kept in a vertical and taut state, thereby improving the guiding effect.

[0026] The assembly and working process of the installation device for preventing the elevator traction wire rope from twisting in this embodiment are as follows: in this embodiment, the wire rope feeding assembly 4 is placed next to the bottom of the shaft 1, wherein the wire rope feeding assembly 4 in this embodiment is a release drum, wherein the release drum is wound with a traction wire rope 6, and the traction wire rope 6 can be drawn out from the release drum; the car 2 is moved to the bottom of the shaft 1, so that the upper top of the car 2 is located below the wire rope feeding assembly 4, and two guide ropes 5 are pulled between the upper top of the car 2 and the top of the shaft 1, and the guide ropes 5 are vertically straightened; wherein a wire rope traction assembly 3 is arranged at the top of the shaft 1, and the wire rope traction assembly 3 can hang down to the bottom of the shaft 1 and be connected with the traction wire rope 6 in the wire rope feeding assembly 4, wherein a traction body 31 is arranged on the wire rope traction assembly 3, and the traction body 31 can be connected with the traction wire rope 6 on the wire rope feeding assembly 4, and at the traction Extension tubes 32 are provided on both sides of the traction body 31, wherein flexible ropes 33 are provided on the extension tubes 32, and the flexible ropes 33 can be connected to the guide ropes 5, so that the movement path of the traction body 31 can be guided by the guide ropes 5, so as to ensure the unity of the path during the movement. Since the extension tubes 32 are provided and the flexible ropes 33 are provided on the extension tubes 32, the gap space between the traction body 31 and the guide ropes 5 is further increased, thereby reducing the interference factors between the traction body 31 and the guide ropes 5, and at the same time increasing the gap space between the traction wire rope 6 and the guide rope 5, reducing the probability of the traction wire rope 6 being entangled with the guide rope 5. Since the extension tubes 32 are connected to the guide ropes 5 through the flexible ropes 33, the flexible characteristics of the flexible ropes 33 can improve the adaptability of the wire rope traction assembly 3 on the guide ropes 5, and avoid jamming between the flexible ropes 33 and the guide ropes 5 during movement.

[0027] Since the wire rope traction assembly 3 can move up and down inside the shaft 1, the traction wire rope 6 can be driven to rise through the wire rope traction assembly 3 to realize the movement of the traction wire rope 6 from bottom to top. Since the movement path of the traction wire rope 6 is from bottom to top, the upper and lower ends of the traction wire rope 6 are respectively fixed during the process of driving the traction wire rope 6 to move, so the traction wire rope 6 can maintain a stable state during the installation process, and since the wire rope traction assembly 3 further improves the movement stability of the wire rope traction assembly 3 by connecting the guide rope 5, the movement trajectory of the traction wire rope 6 is guaranteed to be unified, the control degree of the traction wire rope 6 is improved, the stability of the traction wire rope 6 during the movement is guaranteed, and the traction wire rope 6 is prevented from swinging during the movement, resulting in hooking with objects in the shaft 1 or entanglement with the remaining traction wire ropes 6, and the wire rope traction assembly 3 is connected through the guide rope 5, so that the wire rope traction assembly 3 is always subject to a lateral limiting effect during the movement, thereby improving the stability of the traction wire rope 6 in the lateral direction.

Through the extension tube 32 and the flexible rope 33, a larger gap can be set between the guide ropes 5 on both sides, so as to avoid interference and reduce the risk of entanglement of the traction wire rope 6.

[0029] like Figure 2 , 3 As shown, the wire rope traction assembly 3 is provided with a guide round tube 311 and a guide clamping assembly 312, the traction wire rope 6 passes through the guide clamping assembly 312 to form a rope loop 61, the rope loop 61 is sleeved on the guide round tube 311, and a rope blocking plate 313 is movably connected to the guide round tube 311. The traction wire rope 6 can form a rope loop 61 structure through the guide round tube 311 and the guide clamping assembly 312, and due to the round tube structure of the guide round tube 311, the traction wire rope 6 will not bend, and it is ensured that the traction wire rope 6 can be effectively fixed and connected.

[0030] like Figure 2 , 3As shown, the guide clamping assembly 312 includes a guide clamping plate 314 and a bottom rope clamp 315. After the traction wire rope 6 passes through the bottom rope clamp 315 and the guide clamping plate 314, it is bent back and connected to the bottom rope clamp 315 again to form a rope loop 61. The rope loop 61 structure of the traction wire rope 6 is fixed by the bottom rope clamp 315, and the guide clamping plate 314 allows the traction wire rope 6 to be fixed even after the bottom rope clamp 315 is removed.

[0031] like Figure 4 As shown, the wire rope traction assembly 3 includes a transition traction unit 34, which is arranged at the top of the hoistway 1. A terminal traction unit 35 is movably connected above the top of the hoistway 1. The traction wire rope 6 is lifted to the top of the hoistway 1 by the transition traction unit 34 and then transferred to the terminal traction unit 35. By dividing the wire rope traction assembly 3 into the transition traction unit 34 and the terminal traction unit 35, the installation space can be utilized to the maximum extent, and the installation flexibility of the wire rope traction assembly 3 is improved.

[0032] The assembly process of the installation device for preventing the elevator traction wire rope from twisting in this embodiment is as follows: in this embodiment, the wire rope feeding assembly 4 is placed next to the bottom of the shaft 1, wherein the wire rope feeding assembly 4 in this embodiment is a release drum, wherein the release drum is wound with a traction wire rope 6, and the traction wire rope 6 can be drawn out from the release drum; the car 2 is moved to the bottom of the shaft 1, so that the upper top of the car 2 is located below the wire rope feeding assembly 4, and two guide ropes 5 are pulled between the upper top of the car 2 and the top of the shaft 1, and the guide ropes 5 are vertically straightened; wherein a wire rope traction assembly 3 is arranged at the top of the shaft 1, and the wire rope traction assembly 3 can be drooped down to the bottom of the shaft 1 and connected with the traction wire rope 6 in the wire rope feeding assembly 4, wherein a traction body 31 is arranged on the wire rope traction assembly 3, and the traction body 31 can be connected with the traction wire rope 6 on the wire rope feeding assembly 4, and Extension tubes 32 are provided on both sides of the body 31, wherein the extension tubes 32 are provided with flexible ropes 33, and the flexible ropes 33 can be connected to the guide ropes 5, so that the movement path of the traction body 31 can be guided by the guide ropes 5, so as to ensure that the path is unified during the movement. Since the extension tubes 32 are provided and the flexible ropes 33 are provided on the extension tubes 32, the gap space between the traction body 31 and the guide ropes 5 is further increased, thereby reducing the interference factors between the traction body 31 and the guide ropes 5, and at the same time increasing the gap space between the traction wire rope 6 and the guide rope 5, reducing the probability of the traction wire rope 6 being entangled with the guide rope 5. Since the extension tubes 32 are connected to the guide ropes 5 through the flexible ropes 33, the flexible characteristics of the flexible ropes 33 can improve the adaptability of the wire rope traction assembly 3 on the guide ropes 5, and avoid jamming between the flexible ropes 33 and the guide ropes 5 during movement.

[0033] Furthermore, in the present embodiment, the wire rope traction assembly 3 includes an over-traction unit and a terminal traction unit 35, wherein the terminal traction unit 35 is arranged above the transition traction unit 34. In the present embodiment, the transition traction unit 34 includes a traction body 31, an extension tube 32, and a flexible rope 33, while the terminal traction unit 35 is a hemp rope arranged on the machine room. When the transition traction unit 34 drives the traction wire rope 6 to move to the neck of the shaft 1, the traction wire rope 6 is connected to the terminal traction unit 35 to continue to move, and the traction wire rope 6 is controlled to be connected to the counterweight unit, thereby providing sufficient installation space for the transition traction unit 34. In the case of insufficient space in the future, traction is continued through the terminal traction unit 35.

[0034] In this embodiment, the traction body 31 includes a guide tube 311 and a guide clamping assembly 312. The guide tube 311 is arranged above the guide clamping assembly 312. There are two guide tubes 311, which can be connected to two traction wire ropes 6. Similarly, the guide clamping assembly 312 can also clamp two traction wire ropes 6, and can drive the two traction wire ropes 6 to be installed in one displacement, thereby improving the installation efficiency of the traction wire ropes 6. In actual applications, the number of traction wire ropes 6 installed at one time can be increased or decreased according to needs; after the traction wire rope 6 passes through the guide clamping assembly 312, it is connected to the guide clamping assembly 312 again to form a rope loop 61 structure, which can hold the rope The sleeve 61 is sleeved on the guide circular tube 311, so that the bending structure of the traction wire rope 6 is set on the guide circular tube 311, avoiding bending caused by the bending of the traction wire rope 6 and ensuring the integrity of the traction wire rope 6; and in order to ensure that the rope sleeve 61 formed on the traction wire rope 6 will not fall out of the guide circular tube 311, a rope stop plate 313 is detachably connected to the guide circular tube 311, and the rope stop plate 313 is connected to the guide circular tube 311 by bolts or other detachable connecting parts. When installing or removing the rope sleeve 61, the rope stop plate 313 is removed. The rope stop plate 313 can ensure that the rope sleeve 61 is always set and stably connected to the guide circular tube 311, thereby ensuring stability during the process of lifting the traction wire rope 6.

[0035] Furthermore, in the present embodiment, the guide clamping assembly 312 includes a bottom rope clamp 315 having a guide clamp plate 314, wherein the guide clamp plate 314 is arranged above the bottom rope clamp 315. In the present embodiment, two guide clamp plates 314 are arranged and are stacked up and down, wherein the guide clamp plate 314 is provided with a hole for the traction wire rope 6 to pass through, and the bottom rope clamp 315 arranged below the guide clamp plate 314 can tighten the end of the traction wire rope 6, so that the traction wire rope 6 forms a rope loop 61, wherein the specific formation method of the rope loop 61 is as follows: the end of the traction wire rope 6 is passed from bottom to top through the bottom rope clamp 315 and the two guide clamp plates 314 above, and then passed through the guide circular tube 311 above the guide clamp plate 314, the traction wire rope 6 is bent back and downward on the guide circular tube 311, and is reconnected with the bottom rope clamp 315 to form a rope clamp structure, and the rope retaining plate 313 is connected to the guide circular tube 311.

[0036] Since the wire rope traction assembly 3 can move up and down inside the shaft 1, the traction wire rope 6 can be driven to rise through the wire rope traction assembly 3 to realize the movement of the traction wire rope 6 from bottom to top. Since the movement path of the traction wire rope 6 is from bottom to top, the upper and lower ends of the traction wire rope 6 are respectively fixed during the process of driving the traction wire rope 6 to move, so the traction wire rope 6 can maintain a stable state during the installation process, and since the wire rope traction assembly 3 further improves the movement stability of the wire rope traction assembly 3 by connecting the guide rope 5, the movement trajectory of the traction wire rope 6 is guaranteed to be unified, the control degree of the traction wire rope 6 is improved, the stability of the traction wire rope 6 during the movement is guaranteed, and the traction wire rope 6 is prevented from swinging during the movement, resulting in hooking with objects in the shaft 1 or entanglement with the remaining traction wire ropes 6, and the wire rope traction assembly 3 is connected through the guide rope 5, so that the wire rope traction assembly 3 is always subject to a lateral limiting effect during the movement, thereby improving the stability of the traction wire rope 6 in the lateral direction.

Use the fixing clamp 8 to clamp all the traction steel ropes 6 on the fixing clamp 8 according to the serial number according to the number of the traction steel ropes 6, reserve the length of the traction steel ropes 6 according to the position of the car 2, and cut off the excess traction steel ropes 6; j. Make the rope end assembly of the car 2 and fix the traction wire rope 6 on the car frame.

[0041] Embodiment 4: Different from Example 3, in this embodiment, after the traction wire rope 6 is connected to the counterweight assembly 7, the connection between the wire rope traction assembly 3 and the traction wire rope 6 is loosened, so that the wire rope traction assembly 3 and the traction wire rope 6 are in an incompletely connected state, and the wire rope traction assembly 3 can slide relative to the traction wire rope 6, so that the traction wire rope 6 can be further trimmed during the process of the wire rope traction assembly 3 moving back to the bottom, thereby ensuring the stability of the position of the traction wire rope 6. At this time, the top of the traction wire rope 6 is already connected to the counterweight assembly 7 and remains fixed. When the wire rope traction assembly 3 moves to the bottom, since the wire rope traction assembly 3 and the traction wire rope 6 are in an incompletely connected relative sliding state, it is possible to ensure that the bottom of the traction wire rope 6 is also in a relatively fixed state, which is convenient for the staff to sort it out.
