Description

Technical Field

[0001] The utility model relates to an elevator rope retaining device, in particular to a rotatable and adjustable elevator rope retaining device. Background Art

[0002] An elevator is a special equipment installed in a building to provide height change. The driving of the elevator is powered by a traction machine at the top, and the elevator car and the counterweight device are connected through traction ropes to lift the elevator car. In order to reduce the power consumption of the traction machine and reduce the volume of the traction machine, rope wheels are installed on the elevator car and the counterweight device, and the traction ropes are wound around the rope wheels to reduce the required driving force.

[0003] The spacing between multiple traction ropes and the traction direction of the traction ropes are restricted by the rope grooves provided on the elevator rope wheels. However, the depth of the rope grooves is affected by the processing technology and cannot exceed the diameter of the rope wheels. Therefore, when the traction ropes are running, the problem that the traction ropes are separated from the rope grooves easily occurs, resulting in the problem of elevator vibration and affecting safety and comfort.

[0004] In order to solve the problem that the traction ropes are separated from the rope grooves, a rope retaining device is provided on the rope wheel to restrict the position of the traction ropes. The existing rope retaining device usually uses a rope retaining rod fixed on the rope wheel frame outside the rope wheel to restrict the traction ropes to prevent the traction ropes from separating from the rope grooves. However, the rope retaining device of this structure has a fixed restriction angle for the traction ropes and cannot adapt to different incoming and outgoing groove angles of the steel wire ropes, and the protection performance for the traction ropes is average. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a rotatable and adjustable elevator rope retaining device. The utility model has the characteristics that the protection angle is adjustable and is applicable to the incoming / outgoing groove angles of different traction steel wire ropes on the deflector sheaves.

[0006] The technical solution of the utility model: A rotatable and adjustable elevator rope retaining device includes a pair of mounting seats installed on a rope wheel beam. Rotating plates are rotatably installed on the opposite sides of the two mounting seats, and fixing bolts are further provided between the mounting seats and the rotating plates. A rope retaining sleeve is provided between the two rotating plates.

[0007] In the rotatable and adjustable elevator rope retaining device described above, a first long circular hole is provided at the top of the mounting seat, and a locking bolt connected to the rope wheel beam is provided in the first long circular hole.

[0008] In the rotatable and adjustable elevator rope retaining device described above, a rotating bolt connected to the mounting seat is provided on the rotating plate, so that the rotating plate and the mounting seat can rotate relative to each other without falling off.

[0009] In the aforementioned rope blocking device for an elevator that can be rotated and adjusted, a second oblong hole is provided on the side surface of the mounting base, and a third oblong hole is provided on the connecting plate. A fixing bolt passes through the second oblong hole and the third oblong hole to connect and fix the mounting base and the connecting plate.

[0010] In the aforementioned rope blocking device for an elevator that can be rotated and adjusted, both ends of the rope blocking sleeve are connected to the connecting plate through rope blocking bolts.

Detailed Embodiment

[0022] The present utility model will be further described below in conjunction with the drawings and embodiments, but it shall not be used as a basis for limiting the present utility model.

[0023] In the description of the present utility model, it should also be noted that, unless otherwise clearly specified and defined, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] Embodiment:

[0025] As Figures 1-4 shown, a rope blocking device for an elevator that can be rotated and adjusted includes a pair of mounting seats 1 installed on a rope wheel beam 4. Rotating connection plates 2 are installed on the opposite sides of the two mounting seats 1. A fixing bolt 21 is also provided between the mounting seat 1 and the connection plate 2. A rope blocking sleeve 3 is provided between the two connection plates 2.

[0026] A first long circular hole 11 is provided at the top of the mounting seat 1, and a locking bolt 12 connected to the rope wheel beam 4 is provided in the first long circular hole 11.

[0027] One end of the connection plate 2 away from the rope blocking sleeve 3 is provided with a rotating bolt 22 connected to the mounting seat 1. The rotating bolt 22 is not tightened as a rotating shaft, so that the connection plate 2 and the mounting seat 1 can rotate relative to each other without falling off.

[0028] A second long circular hole 13 is provided on the side surface of the mounting seat 1, and a third long circular hole 23 is provided on the connection plate 2. The fixing bolt 21 passes through the second long circular hole 13 and the third long circular hole 23 to connect and fix the mounting seat 1 and the connection plate 2.

[0029] Both ends of the rope blocking sleeve 3 are connected to the connection plate 2 through rope blocking bolts 31.

[0030] The surface of the rope blocking sleeve 3 is a smooth surface.

[0031] When the present utility model is used, according to the out / in groove angle of the traction steel wire rope 41 on the deflector sheave 42, the connection plate 2 is rotated to adjust the included angle between the connection plate 2 and the mounting seat 1. The included angle α can be controlled to be ±10°. At the same time, through the cooperation of the first long circular hole 11 and the locking bolt 12, the position of the mounting seat 1 on the mounting beam of the deflector sheave 42 is adjusted so that the rope blocking sleeve 3 is located at the tangent point of the traction steel wire rope 41 and the deflector sheave 42.

[0032] After the positions of the mounting seat 1 and the connection plate 2 are adjusted in place, the locking bolt 12 and the fixing bolt 21 are tightened to fix the mounting seat 1 and the connection plate 2 respectively, so as to stabilize the structure, and the risk of the steel wire rope 41 coming out of the groove is effectively reduced through the rope blocking sleeve 3.

[0033] Moreover, the rope retaining sleeve 3 abuts between the two connecting plates 2 to prevent the connecting plates 2 from deforming when the rope retaining bolt 31 is tightened. At the same time, the smooth surface of the rope retaining sleeve 3 faces the steel wire rope 41 to prevent the rope retaining sleeve 3 from cutting the steel wire rope 41 when the steel wire rope 41 jumps off the rope.

[0034] The parts not detailed in this utility model are prior arts and thus will not be specifically described herein.
