Description

Technical Field

[0001] This utility model relates to the field of elevator wire rope fixing technology, and in particular to an elevator wire rope fixing device. Background Technology

[0002] As the core load-bearing component that supports the weight of the elevator car and enables lifting and lowering motion, the elevator wire rope is connected to the car at one end and needs to be fixed to a specific position on the machine room load-bearing structure or car frame at the top of the elevator shaft by a fixing device to ensure that the wire rope always maintains the preset force trajectory and tension state during long-term reciprocating motion.

[0003] However, existing elevator wire rope fixing devices still have shortcomings in use, making it difficult to effectively solve the problem of wire rope jumping or shaking during elevator ascent and descent. Most common fixing devices currently use simple clamping structures, which can only achieve static fixing of the wire rope and cannot adapt to dynamic stress changes during elevator operation. When the elevator is running, the wire rope is prone to shaking due to instantaneous tension fluctuations. This movement may cause repeated friction between the wire rope and the clamping part of the fixing device, accelerating surface wear, shortening its service life, and even potentially causing safety hazards such as wire breakage or strand breakage due to localized stress concentration.

[0004] Therefore, how to optimize the device to fix the wire rope and suppress the shaking when the wire rope is raised and lowered has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0037] Reference Figure 4 and Figure 6 Two limiting plates 5 are symmetrically arranged on both sides of the fixing block 3. Each limiting plate 5 is provided with a second fixing groove 9 that corresponds one-to-one with the first fixing groove 4 near the side wall of the fixing block 3. The transverse cross section of the second fixing groove 9 is also arc-shaped.

[0038] The fixing component installed on the fixing box 1 is connected to the limiting plate 5, which is used to move the limiting plate 5 closer to or away from the first fixing groove 4.

[0039] Reference Figure 3 The fixing assembly includes a screw 7 and a guide rod 8. One end of the screw 7 is threaded through the side wall of the fixing box 1 and is rotatably connected to the limiting plate 5. The guide rod 8 slides through the side wall of the fixing box 1 and is fixedly connected to the limiting plate 5. Two guide rods 8 are symmetrically arranged on both sides of the screw 7.

[0040] The end of the screw 7 away from the fixed box 1 is connected to the knob 10.

[0041] Reference Figure 7The buffer components are provided on the side walls opposite to the first fixing groove 4 and the limiting plate 5. Specifically, the buffer components are provided on the side walls opposite to the first fixing groove 4 and the second fixing groove 9.

[0042] The buffer ends of the buffer assembly are all rotatably connected to guide balls 6.

[0043] The buffer assembly includes a fixed sleeve 12, a fixed rod 11, and a first spring 13. The first spring 13 is installed inside the fixed sleeve 12. The two ends of the first spring 13 are fixedly connected to the bottom of the inner wall of the fixed sleeve 12 and the fixed rod 11, respectively. The fixed sleeves 12 are fixedly connected to the side walls opposite to the first fixed groove 4 and the second fixed groove 9. One end of the fixed sleeve 12 is slidably sleeved on the periphery of one end of the fixed rod 11. The other end of the fixed rod 11 is rotatably connected to a guide ball 6, which is used to slide with the side wall of the wire rope.

[0044] Reference Figure 4 and Figure 6 The top of the fixed box 1 is provided with a through hole 14 for the wire rope to pass through. The wire rope sliding on the fixed pulley 2 extends out from the through hole 14. Two cleaning components are arranged opposite each other in the through hole 14, and the two cleaning components clean the surface of the wire rope.

[0045] The cleaning assembly includes a slider 16, a connecting rod 17, a brush plate 18, and a second spring. The fixed box 1 is provided with a slide groove 15 that communicates with the through hole 14. The second spring is provided inside the slide groove 15. The two ends of the second spring are fixedly connected to the bottom of the inner wall of the slide groove 15 and the connecting rod 17, respectively. The slide groove 15 and the connecting rod 17 are slidably connected. The end of the connecting rod 17 away from the second spring is connected to the arc-shaped brush plate 18. The bristles of the brush plate 18 are used to remove dust from the surface of the wire rope.

[0046] The end of the connecting rod 17 away from the second spring is provided with a U-shaped mounting groove 19. The end of the brush plate 18 near the connecting rod 17 is fixedly connected with a U-shaped mounting rod 20. The mounting groove 19 and the mounting rod 20 are detachably connected by a first fastener, which is a bolt. When the bristles of the brush plate 18 need to be replaced, the first fastener is removed, and the mounting rod 20 is taken out from the mounting groove 19 to replace the new brush plate 18.

[0047] The working principle of this utility model is as follows: In use, firstly, one end of the elevator wire rope is inserted through the through hole 14 at the top of the fixed box 1, extends downward and is installed in the groove of the fixed pulley 2, and then exits through the through hole 14.

[0048] Subsequently, the operator rotates the knobs 10 on both sides of the fixing box 1, causing the screw 7 to rotate. When the screw 7 rotates, it drives the translational movement of the limiting plate 5, causing the two limiting plates 5 to move closer to the fixing block 3, until the second fixing groove 9 on the limiting plate 5 and the first fixing groove 4 on the fixing block 3 together form a clamping space that matches the diameter of the wire rope, and the guide ball 6 is in close contact with the surface of the wire rope. At this time, stop rotating the knob 10. If it is necessary to adjust the tightness of the limit or replace the wire rope, rotate the knob 10 in the opposite direction to move the limiting plate 5 away from the fixing block 3.

[0049] During elevator operation, the wire rope slides along the groove of the fixed pulley 2, which in turn drives the guide ball 6 to rotate. When the wire rope vibrates, it applies pressure to the guide ball 6. The guide ball 6 compresses the first spring 13 inside the fixed sleeve 12 through the fixed rod 11. The first spring 13 absorbs part of the impact force and plays a buffering role.

[0050] When the wire rope moves up and down along the through hole 14, the two brush plates 18 inside the through hole 14 will clean the surface of the wire rope; the second spring will push the brush plate 18 toward the wire rope to ensure that the bristles on the inside of the brush plate 18 are in close contact with the surface of the wire rope; the bristles can sweep away the dust, particles and other impurities attached to the surface of the wire rope.
