Detailed Description
An embodiment of the elevator system of the invention:
the specific structure of the elevator system is shown in fig. 1-4, and comprises a well and a lift car capable of lifting along a track in the well, wherein a lift car rope return wheel 9 is arranged on the lift car, and a rotary elevator rope head device is arranged in the well. A rotary elevator rope head device comprises a supporting beam and a rope head assembly rotatably arranged on the supporting beam. One end of the wire rope 8 is fixed on the rope head assembly, and the other end is fixed on a well or a traction machine after passing through the car rope return wheel 9, so that a pulley block is formed. The displacement of the car return sheave 9 is in the vertical direction without a horizontal component when the car runs up and down along the track.
The rotation axis of the rope head assembly is parallel to the rotation axis of the car return sheave 9, and the distance between the two in the horizontal direction is l. When the steel wire rope 8 between the car rope return wheel 9 and the rope head assembly is in a tensioning state, the included angle between the steel wire rope 8 and the horizontal plane is a. From the geometrical relationship, it is known that the following geometrical relationship is satisfied between the vertical distance h between the center point of the car return sheave 9 and the rotation axis center line of the rope hitch assembly: h=f (l, a). When l and a are determined, the value of h is also uniquely determined. After the elevator installation is completed, l is a constant value. In the lifting process of the elevator car, the elevator car and the elevator car rope return wheel 9 are not horizontally displaced, so that the value of l is kept unchanged in the process. Therefore, the h value at any time can be calculated by measuring the a value in real time.
The support beam comprises a left beam body A, a right beam body B which are arranged at intervals left and right, and a support shaft 4 which is fixed above the left beam body and the right beam body by a U-shaped clamping ring 3. The left and right beam bodies comprise a first bottom beam 1 and a second bottom beam 2, the first and second bottom beams extend along the front and rear directions, the cross section shapes of the first and second bottom beams are I-shaped, and the second bottom beam 2 is fixed above the first bottom beam 1. The supporting shaft 4 extends along the horizontal direction, and a rope head assembly 5 is axially limited on the shaft section between the left beam body and the right beam body and is circumferentially rotationally arranged.
The rope end component 5 comprises a connecting frame and a rope end fixing plate 53 fixed at the lower end of the connecting frame, and rope end rod perforations 54 for the counterweight rope end rods to pass through are formed in the rope end fixing plate 53. The connecting frame includes two frame bodies 51 arranged at a left-right interval and a shaft sleeve 52 fixed between the two frame bodies 51, and the two frame bodies 51 are arranged at a left-right interval and are called a left frame body 51a and a right frame body 51b. The diameter of the sleeve 52 is larger than the diameter of the support shaft 4, and the sleeve is circumferentially rotatably sleeved on the support shaft 4. The support shaft 4 is provided with C-shaped circlips 7 on both sides of the connecting frame for limiting the axial movement of the connecting frame along the support shaft, and the C-shaped circlips 7 are fixed on the support shaft 4 to stop the axial movement of the corresponding frame body 51 along the support shaft.
In a normal state, the upper end surface of the rope end fixing plate 53 is parallel to the horizontal plane, so that the sensor 10 for detecting the angle between the rope end fixing plate 53 and the horizontal plane can be fixed on the upper end surface of the rope end fixing plate 53. In the lifting process of the car, as the included angle a between the steel wire rope 8 and the horizontal plane changes, the rope head assembly 5 rotates along with the steel wire rope 8 to a state that the axial direction of the counterweight rope head rod is collinear with the extending direction of the steel wire rope 8, and at the moment, the included angle a between the rope head fixing plate 53 detected by the sensor 10 and the horizontal plane is the complementary angle with the included angle a.
In practice, the angle signal detected by the sensor 10 may be sent to the controller, and after the car height h is calculated in the controller, sent to a display in the car or a remote display for inspection and maintenance.
To increase the strength of the rope end assembly, the left and right frames are provided with through holes extending from left to right, and both ends of the shaft sleeve 52 are inserted into the through holes of the corresponding frames and supported by the hole edges of the through holes.
In order to avoid the abrasion of the shaft sleeve 52, two ends of the shaft sleeve 52 are sleeved on the support shaft 4 through the sleeve 6, and the aperture of the sleeve 6 is matched with the diameter of the support shaft 4 to be assembled on the support shaft 4 in a clearance manner; of course, in other embodiments, the two ends of the shaft sleeve can be rotatably arranged on the supporting shaft through the rolling bearing, and when the rolling bearing is used, the rope end fixing device of the invention can be suitable for occasions with larger shaking of the steel wire rope.
To further increase the strength of the rope end assembly 5, the rope end fixing plate 53 is a groove-shaped member with a downward opening, and the left frame body 51a and the right frame body 51b are correspondingly provided with clamping grooves adapted to the cross-sectional shape of the rope end fixing plate 53, and two ends of the rope end fixing plate 53 are inserted into the corresponding clamping grooves and supported by edges of the clamping grooves.
In other embodiments, the connecting frame may be in a straight structure, so long as the upper end of the connecting frame is rotatably arranged on the supporting shaft; of course, the connecting frame can also be fixed on the supporting shaft, and the supporting shaft is circumferentially rotated and axially limited between the left beam body and the right beam body; of course, the support beam may be of other structures, or the rope end assembly may be disposed on the overhanging end of the support shaft, but the overhanging end of the support shaft is damaged.
