Description

Technical Field

[0001] The utility model relates to the field of traction sheave equipment, in particular to a traction sheave traction rope anti-deviation structure. Background Art

[0002] The traction sheave is the rope pulley on the traction machine, also known as the traction sheave or drive sheave. It is the device that transmits the traction power of the elevator. It transmits power through the friction between the traction wire rope and the rope grooves on the traction sheave flange. It is installed on the worm gear shaft in the reducer. The traction rope is prone to deflection when the traction sheave is in use.

[0003] According to the patent document with the existing publication number CN205397805U, a traction sheave for preventing the traction rope from deviating is disclosed, which includes a traction sheave body and is characterized in that, at both ends of the traction sheave body along the axial direction, a retaining ring is provided, the diameter of the retaining ring is larger than the outer ring diameter of the traction sheave body, and at least one of the two retaining rings is a disassembly retaining ring, which is detachably fixed to the traction sheave body. When this technical solution is in use, since the diameter of the retaining ring is larger than the outer ring diameter of the traction sheave body, the effect of preventing the traction rope from deviating can be achieved. Secondly, the retaining ring is set to a detachable structure, so that when installing or removing the traction rope, the disassembly retaining ring can be removed to eliminate the impact of the retaining ring on the traction rope caused by the installation or disassembly. With respect to the above technical solution, although this solution realizes the prevention of the traction rope from deviating, the tightness of the traction rope cannot be adjusted during use, which is inconvenient during use.

[0021] See also Figures 1 to 5 The utility model provides a technical solution: a traction sheave traction rope anti-deviation structure, comprising a traction sheave 1, a winding sheave 6 is fixedly installed between the traction sheaves 1, a mounting groove 2 is opened on the side of the traction sheave 1, a fixing seat 3 is installed inside the mounting groove 2, a support block 4 is welded between the fixing seat 3 and the mounting groove 2, a threaded hole 5 is opened on the fixing seat 3, a limiting roller 7 is movably installed on the top of the traction sheave 1, a supporting roller 8 is installed at the bottom of the traction sheave 1, a movable seat 9 is movably installed on one side of the traction sheave 1, a support rod 17 is welded to the bottom of the movable seat 9, the support roller 8 is rotatably installed on the support rod 17, the support roller 8 and the limiting roller 7 are distributed at the top and bottom of the traction sheave 1 at the same time, and the traction rope on the winding sheave 6 is doubly limited.

[0022] In this embodiment, a fixed column 13 is welded on the movable seat 9, and a fixed disk 14 is welded to one end of the fixed column 13. A mounting seat 15 is fixedly installed on the fixed disk 14, and a power mechanism 16 is fixedly installed on the mounting seat 15. The power mechanism 16 is a DC motor, and the DC motor drives the rotation of the rotating seat 10. An output shaft is installed on the power mechanism 16, and a rotating seat 10 is welded to one end of the output shaft. The rotating seat 10 is installed on the movable seat 9 through a bearing seat 18. A connecting seat 11 is welded on the rotating seat 10, and a support seat 12 is movably installed on the connecting seat 11. The support seat 12 It is rotationally connected to the limiting roller 7, and a connecting rod 19 is welded on the connecting seat 11. A cavity 20 is opened on the support seat 12, and a limiting groove 21 is opened on the inner wall of the cavity 20. A limiting block 22 is movably installed inside the limiting groove 21, and a supporting mechanism 23 is fixed between the limiting block 22 and the limiting groove 21. One end of the limiting block 22 is fixed on the connecting rod 19, and the limiting roller 7 drives the support seat 12 to move on the connecting seat 11. The supporting mechanism 23 is a supporting spring, which effectively avoids damage to the traction rope due to excessive extrusion pressure of the limiting roller 7, thereby realizing the buffering displacement of the limiting roller 7.

[0023] When the device is in use, one side of the traction wheel 1 is fixedly installed on the transmission motor, and the transmission motor drives the traction wheel 1 to rotate later, and the movable seat 9 is fixedly installed at the opposite position of the traction wheel 1 through the fixed plate 14 on the fixed column 13.

After the traction rope is loosened, the power mechanism 16 is started to drive the rotating seat 10 to rotate, and the rotating seat 10 is rotated. The rotation of the movable seat 10 drives the support seat 12 to rotate through the connecting seat 11. After the support seat 12 rotates, it squeezes the top of the traction rope, and the traction rope is re-tightened under the squeezing. After tightening, it effectively prevents the traction rope from being discharged from the winding wheel 6. When the connecting seat 11 applies pressure to the limiting drum 7, the supporting mechanism 23 effectively avoids damage to the traction rope caused by excessive squeezing force of the limiting drum 7, thereby realizing the buffering displacement of the limiting drum 7. When the traction wheel 1 rotates, the movable seat 9 remains stationary, so that the support drum 8 is always limited and installed at the bottom of the traction wheel 1 for limiting.
