Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to an elevator installation system. Background Technology

[0002] In existing elevator installation systems, the main unit typically employs a design with separate left and right drums, located at both ends of the main shaft and supported by bearings. While this structure allows for the winding and unwinding of the wire rope, the bearing support points are only located at both ends of the main shaft, and the distance between these two support points is relatively small compared to the entire length of the main shaft. This results in significant bending moments on the main shaft during operation. When the motor drives the drums to lift the elevator car, the main shaft experiences uneven traction from the wire rope, transferring excessive force to the bearings. Over time, the bearings will bear forces far exceeding their actual load capacity, leading to overheating, wear, and fatigue damage. This directly shortens the bearing's lifespan, affecting the continuity of elevator installation work and increasing operating costs. Utility Model Content

[0003] To overcome the above shortcomings, the purpose of this utility model is to provide an elevator installation system. By setting a strong drive host at the bottom of the elevator shaft, the motor drives the strong drive host so that the drum controls the elevator to rise and fall by means of steel wire rope. Furthermore, by using the first single rope groove and the second single rope groove to wind the steel wire rope, the problem of uneven force caused by traditional traction machines is avoided, thereby improving the stability of elevator operation.

[0004] Technical solution: This utility model discloses an elevator installation system, including:

[0005] The forced drive unit is installed at the bottom of the elevator shaft. The forced drive unit includes a motor and a drum driven by the motor. The two ends of the drum are respectively provided with a first single rope groove and a second single rope groove.

[0006] An elevator, wherein the elevator is connected to the drive unit via a steel wire rope and is driven to move up and down within the elevator shaft by the drive unit;

[0007] A guide unit installed at the top of the elevator shaft is used to guide the wire rope connecting the drum and the elevator.

[0008] Furthermore, the first single rope groove and the second single rope groove are symmetrically arranged, and the outer walls of the first single rope groove and the second single rope groove have interlocking grooves that are spirally opposite to each other, the interlocking grooves being used to embed the steel wire rope.

[0009] Furthermore, the guiding unit includes a first guide wheel assembly and a second guide wheel assembly installed side by side at the top of the elevator shaft, wherein the first guide wheel assembly is aligned with the first single rope groove, and the second guide wheel assembly is aligned with the second single rope groove.

[0010] Furthermore, the first guide wheel assembly includes at least two rollers arranged in a straight line; the second guide wheel assembly includes at least two rollers arranged in a straight line.

[0011] Furthermore, a first guide rail and a second guide rail are respectively installed on opposite sides of the elevator to guide the elevator to move up and down.

[0012] Furthermore, the second guide rail is adjacent to the drum, which also includes a groove located between the first single rope groove and the second single rope groove. The second guide rail is located within the groove to save space.

[0013] Furthermore, the wire rope includes a first wire rope and a second wire rope. The first wire rope is wound in the first single rope groove and connected to the elevator through a first guide wheel assembly. The second wire rope is wound in the second single rope groove and connected to the elevator through a second guide wheel assembly.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) This utility model sets a strong drive host at the bottom of the elevator shaft. The motor drives the strong drive host so that the drum controls the elevator to rise and fall by means of steel wire rope. The uneven force caused by the traditional traction machine is avoided by winding the steel wire rope through the first single rope groove and the second single rope groove, thereby improving the stability of the elevator operation.

[0016] (2) The first single rope groove and the second single rope groove are respectively provided at both ends of the drum, and the grooves on the outer wall of the two are spirally opposite, so that the tension of the wire rope is balanced during the winding process, avoiding deviation and slippage, reducing wear, and extending the service life of the wire rope.

[0017] (3) A first guide wheel group and a second guide wheel group corresponding to the first single rope groove and the second single rope groove are respectively installed at the top of the elevator shaft so that the wire rope can run smoothly along the corresponding path and ensure the smooth lifting and lowering of the elevator.

[0018] (4) The elevator is provided with a first guide rail and a second guide rail on opposite sides.

The implementation methods of this utility model will now be described based on its overall structure.

[0026] like Figures 1 to 3 As shown, this utility model discloses an elevator installation system, including:

[0027] The forced drive host 1 is installed at the bottom of the elevator shaft. The forced drive host 1 includes a motor 11 and a drum 12 driven by the motor 11. The two ends of the drum 12 are respectively provided with a first single rope groove 121 and a second single rope groove 122.

[0028] Elevator 2, which is connected to the drive unit 1 via a steel wire rope and is driven to move up and down in the elevator shaft by the drive unit 1;

[0029] The guide unit 3 is installed at the top of the elevator shaft and is used to guide the wire rope connecting the drum 12 and the elevator 2.

[0030] With the above structure, the driven motor 1, installed at the bottom of the elevator shaft, serves as the power driver. The motor 11 drives the drum 12 to rotate. The two ends of the drum 12 are a first single rope groove 121 and a second single rope groove 122, respectively, thus enabling the winding and unwinding of the wire rope. One end of the wire rope is connected to the elevator car 2, and the other end is guided by a guide unit 3 installed at the top of the elevator shaft, allowing the elevator 2 to rise and fall along a preset path within the elevator shaft. Because the driven motor 1 is located at the bottom of the shaft, the motor 11 and drum 12 work closely together, outputting a large traction force. Furthermore, the driven motor 1 and elevator 2 maintain a close horizontal distance, thereby improving the space utilization within the elevator shaft.

[0031] Compared to existing elevator installation systems, the main unit typically employs a design with left and right drums 12 positioned separately. These drums 12 are distributed at both ends of the main shaft, passing through it and supported by bearings. The bearing support points are located at both ends of the main shaft, and the distance between these two support points is relatively small compared to the entire length of the main shaft. This results in a large bending moment on the main shaft during operation, leading to uneven traction of the wire rope and transferring excessive force to the bearings. Over long-term use, the bearings will bear forces far exceeding the actual load, easily causing overheating, wear, and fatigue damage, directly shortening their lifespan. This invention addresses this by providing a first single rope groove 121 and a second single rope groove 122 at both ends of the same drum 12. This not only improves the uniformity of force distribution on the wire rope but also effectively extends its service life.

[0032] The first single rope groove 121 and the second single rope groove 122 are symmetrically arranged to ensure that the drum 12 is subjected to balanced force during wire rope winding, preventing uneven loading on one side of the drum 12 due to excessive force, thereby improving the overall operational stability. Reciprocating spiral grooves are respectively provided on the outer walls of the first single rope groove 121 and the second single rope groove 122, allowing the wire rope to embed into the corresponding grooves during winding. Because the grooves are spirally distributed, the wire rope can be arranged along the spiral path of the grooves during winding, avoiding problems such as overlapping, slippage, or local accumulation of the wire rope. Simultaneously, the spirally opposite arrangement of the first single rope groove 121 and the second single rope groove 122 causes the arrangement directions of the wire ropes at both ends to cancel each other out, thus maintaining balance during drum 12 rotation and reducing radial offset and vibration.

[0033] Furthermore, the guide unit 3 is located at the top of the elevator shaft, including a first guide wheel assembly 31 and a second guide wheel assembly 32 installed side by side. The first guide wheel assembly 31 and the second guide wheel assembly 32 are vertically aligned with the first single rope groove 121 and the second single rope groove 122 of the drum 12 at the bottom of the elevator shaft. When the drum 12 rotates, driving the wire rope to wind or unwind, the wire rope can smoothly enter its corresponding guide wheel assembly at the top of the shaft, realizing a change in direction and guidance. The first guide wheel assembly 31 and the second guide wheel assembly 32 are arranged independently, so that the first wire rope 41 and the second wire rope 42 remain parallel and do not interfere with each other during operation, avoiding cross friction or collision between the first wire rope 41 and the second wire rope 42. The first wire rope 41 is wound in the first single rope groove 121 and connected to the elevator 2 through the first guide wheel assembly 31, and the second wire rope 42 is wound in the second single rope groove 122 and connected to the elevator 2 through the second guide wheel assembly 32.

[0034] Preferably, the first guide wheel assembly 31 includes at least two rollers arranged in a straight line, and the second guide wheel assembly 32 also includes at least two rollers arranged in a straight line. Through this straight-line arrangement, the wire rope can sequentially contact multiple rollers as it enters the guide wheel assembly, thus forming a continuous support and guidance path. The straight-line arrangement of the multiple rollers effectively limits the lateral deviation of the wire rope, distributing the force during wire rope tensioning and operation, preventing individual rollers from bearing excessive concentrated loads, and reducing roller wear.

[0035] In this embodiment, a first guide rail 21 and a second guide rail 22 are respectively provided on opposite sides of the elevator 2. These two guide rails work together to define the movement path of the elevator 2 in the shaft, ensuring that the elevator 2 maintains a stable vertical state during ascent and descent. Furthermore, the second guide rail 22 is positioned adjacent to the drum 12. The drum 12 has a groove 123 between the first single rope groove 121 and the second single rope groove 122. The second guide rail 22 is installed within the groove 123, thus achieving spatial complementarity between the second guide rail 22 and the groove 123 of the drum 12, avoiding interference between them and effectively saving installation space within the shaft. Specifically, the symmetrical arrangement of the first guide rail 21 and the second guide rail 22 ensures balanced force distribution during ascent and descent, resulting in smoother operation and improved safety and comfort. Furthermore, the second guide rail 22's location within the groove 123 of the drum 12 also helps to shorten the mechanical link between the elevator 2 and the drive unit in terms of horizontal distance, improving the directness and reliability of force transmission and reducing off-center loads and additional stress.

[0036] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
