Description

Technical Field

[0001] This utility model relates to the field of elevator main frame, and in particular to an elevator V-shaped main frame. Background Technology

[0002] The elevator main frame is the core support structure in the elevator traction system. Its main purpose is to fix and support the elevator main unit, and to realize force transmission, vibration suppression, and safety protection. It is a key component to ensure the stable operation of the elevator. However, in the current technology, the elevator main frame cannot meet the requirements of strong anti-tilt function while also taking into account the diagonal tension function of the wire rope. The diagonal tension of the wire rope (especially the V-shaped winding rope) will generate a horizontal component force on the car through the tilted tension. Improper design can easily lead to problems such as left and right swaying and lateral tilting of the car during operation, accelerated wear of the guide rails and wire ropes, and abnormal noise. Utility Model Content

[0003] The technical problem this invention aims to solve is that the elevator main frame cannot simultaneously meet the requirements of strong anti-tilting and the function of wire rope diagonal tension.

[0004] To solve the above-mentioned technical problems, an elevator V-shaped rope winding main frame is provided, including a traction motor mounting plate, a steel wire rope, a traction motor, and a counter-rope sheave. The traction motor is equipped with a traction sheave, and the frame also includes an anti-tilting component located at the lower end of the traction motor mounting plate. The anti-tilting component is bolted to the main frame support base. The traction sheave is connected to the counter-rope sheave located below the main frame support base via the steel wire rope, forming a V-shaped structure and a V-shaped rope winding path. The steel wire rope moves along the V-shaped rope winding path to realize the rise or fall of the elevator car.

[0005] Preferably, the anti-rollover assembly includes a first reinforcing plate, a second reinforcing plate, and a third reinforcing plate, wherein the length of the second reinforcing plate is longer than that of the first and third reinforcing plates.

[0006] Preferably, the main unit support base is composed of a first support plate, a second support plate and a third support plate, and the first reinforcing plate, the second reinforcing plate and the third reinforcing plate are bolted to the first support plate and the second support plate, and the second reinforcing plate is bolted to the third support plate.

[0007] Preferably, both the anti-tilt assembly and the main unit's support base are made of C-shaped steel; Preferably, the space formed by the first reinforcing plate and the second reinforcing plate restricts the angle of the V-shaped rope winding of the wire rope.

[0008] This invention involves installing an anti-tilt component on the main support base, with both ends of the anti-tilt component connected to the main support base and the traction sheave, respectively. By optimizing the installation positions of the traction sheave, the anti-tilt component, and the anti-roll sheave, the distribution of the wire rope tension is ensured, thereby adjusting the wire rope's inclined (V-shaped rope winding) path.

[0009] Compared with the existing technology, this utility model solves the problem that the elevator main frame cannot meet the requirements of strong anti-tilting while also taking into account the function of wire rope diagonal tension. Attached Figure Description

[0011] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0012] like Figure 1-2 As shown. This utility model provides an elevator V-shaped rope winding main frame, including a traction motor mounting plate 6, a steel wire rope 4, a traction motor, and a counter-rotating sheave 5. A traction sheave 1 is mounted on the traction motor. It also includes an anti-tilting component 2 located at the lower end of the traction motor mounting plate 6. The anti-tilting component 2 is bolted to the main frame support base 3. The traction sheave 1 is connected to the counter-rotating sheave 5 located below the main frame support base 3 via the steel wire rope 4, forming a V-shaped structure and a V-shaped rope winding path. The steel wire rope 4 moves along this V-shaped rope winding path (e.g., ...). Figure 3 As shown in the figure, this enables the elevator car to rise or fall.

[0013] This invention effectively balances lateral force and optimizes force transmission by optimizing the path of the wire rope's inclined tension (V-shaped rope winding). The anti-tilt component plays a crucial role in the optimized triangular structure. The anti-tilt component 2 includes a first reinforcing plate 21, a second reinforcing plate 22, and a third reinforcing plate 23, with the second reinforcing plate 22 being longer than both the first and third reinforcing plates 21 and 23. The first, second, and third reinforcing plates 21 and 22 are made of C-shaped steel. The first and third reinforcing plates 23 are arranged in a mirror-symmetrical manner on the lower sides of the traction motor mounting plate 6, while the second reinforcing plate 22 is located in the middle of the traction motor mounting plate 6 and matches the width of the main support base 3. The first, second, and third reinforcing plates 21, 22, and 23 are all bolted to the main support base 3. The wire rope 4 originates from one end of the traction sheave 1, passes through the space formed between the first reinforcing plate 21 and the second reinforcing plate 22 of the anti-tilting assembly 2, and connects to the elevator car. The other end also passes through the space between the first reinforcing plate 21 and the second reinforcing plate 22 of the anti-tilting assembly 2 and connects to the counterweight via the anti-tilting sheave 5. The traction sheave 1, through the wire rope 4, is connected to the anti-tilting sheave 5 located below the main support base 3, forming a V-shaped structure and a V-shaped rope winding path. The wire rope 4 moves along this V-shaped rope winding path, where the space formed by the first reinforcing plate 21 and the second reinforcing plate 22 restricts the angle of the V-shaped rope winding of the wire rope 4.

[0014] The traction motor is connected to the traction motor mounting plate 6 at the top and to the main support base 3 at the bottom via bolts through the first reinforcing plate 21, the second reinforcing plate 22, and the third reinforcing plate 23 of the anti-tilting component 2. The anti-tilting component 2 provides support for the traction motor mounting plate 6, transferring the reaction force of the traction motor during elevator operation to the main support base 3. The main support base 3 consists of a first support plate 31, a second support plate 32, and a third support plate 33. The specific connection method between the anti-tilting component 2 and the main support base 3 is as follows: the first reinforcing plate 21, the second reinforcing plate 22, and the third reinforcing plate 23 are bolted to the first support plate 31 and the second support plate 32, and the second reinforcing plate 22 is bolted to the third support plate 33. The main support base 3 has pre-drilled mounting screw holes for connecting to the support body (building) via screws. When the elevator is running, the main support base 3 receives the reaction force indirectly transmitted by the anti-tilting component 2, which is then transmitted to the support body (building) through the connectors made of two C-shaped steels at the lower end of the main support base 3.

[0015] Furthermore, to enhance the robustness of the main unit support base 3, both the main unit support base 3 and the anti-tilt component 2 are made of C-shaped steel, with a surface wrapped with t5.0 reinforcing ribs.

[0016] Because this utility model adopts an optimized wire rope oblique pulling (V-shaped rope winding) path, the traction sheave 1 is connected to the anti-rope sheave 5 located below the main unit bearing base 3 via the wire rope 4, forming a V-shaped structure and a V-shaped rope winding path. The wire rope 4 moves along this V-shaped rope winding path. The space formed by the first reinforcing plate 21 and the second reinforcing plate 22 restricts the angle of the V-shaped rope winding of the wire rope 4. Therefore, when the elevator car tilts during operation, the space formed by the first reinforcing plate 21 and the second reinforcing plate 22 can correct the angle of the elevator car's oblique pulling, optimizing the balance of the horizontal component force (lateral force) and strengthening the anti-tilting problem. It achieves both strong anti-tilting and convenient wire rope oblique pulling (V-shaped rope winding method), realizing the effect of both.

[0017] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
