Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.

Examples: the elevator steel cable guiding device comprises a mounting plate unit 1 sleeved on a steel cable B for dragging an elevator car A, a guide wheel unit 2 arranged on the mounting plate unit 1 and used for guiding the steel cable B, and an adjusting rod unit 3 used for adjusting the distance between the guide wheel units 2. The guide wheel units 2 are arranged at the left side and the right side of the steel cable B, so that the steel cable B cannot generate redundant shaking in the operation process, the number of the guide wheel units 2 is generally one for each of the left side and the right side of one steel cable B, and in a preferred scheme, one steel cable B can be provided with four guide wheel units 2. The mounting plate unit 1 supports the guide roller unit 2 above the car a so that the operation of the guide roller unit 2 is not affected by the vibration of the car a.

The mounting plate unit 1 comprises a mounting plate 101, a mounting hole 102 which is arranged on the mounting plate 101 and is used for sleeving the steel cable B, and a support column 103 which is arranged on the car A and is used for supporting the mounting plate 101. Referring to fig. 1 to 3, a wire rope B is passed through the mounting plate 101 from top to bottom through the mounting hole 102 and is connected with the upper end connector of the car a for traction of the passenger elevator. A mounting plate 101 is located above the car a for mounting the guide pulley unit 2.

The guide wheel unit 2 includes a guide wheel 201 for guiding the wire rope B, and a support arm 202 rotatably mounted on the mounting plate 101 for adjusting an angle of the guide wheel 201. The lower end of the support arm 202 is mounted on a bearing embedded in the mounting plate 101, about which bearing the lower end of the support arm 202 is rotatable, and the upper end is rotatably mounted with a guide wheel 201. The guide pulley 201 is provided with a groove on a side close to the steel cable B, and can be locked on the steel cable B, so that the steel cable B can move along the tangential direction of the guide pulley 201.

The guide wheel unit 2 further comprises a sliding groove 203 arranged on the supporting arm 202; the adjusting lever unit 3 includes a slide column 301 engaged with the slide groove 203, a link column 302 connected to the slide column 301, a lifting column portion 303 mounted on the link column 302, and a rotating disk portion 304 for adjusting the height of the lifting column portion 303. Referring to fig. 4 to 5, the lifting column part 303 can be driven to move up and down by the rotation of the rotating disk part 304, and the linking column 302 can be driven to move up and down together when the lifting column part 303 moves up and down. The sliding columns 301 embedded into the sliding grooves 203 are arranged at the two ends of the linkage column 302, and when the sliding columns 301 slide downwards, the guide wheels 201 at the two ends of the steel cable B can be drawn towards the middle, so that the adjustment effect on the distance between the guide wheels 201 is realized.

The lifting column part 303 includes a lifting column 303a, a clamping plate 303b provided on the lifting column 303a for clamping the linkage column 302, and a rack 303c provided on the clamping plate 303b and engaged with the rotating disk part 304. The rotating disk portion 304 includes a rotating disk 304a, a rotating column 304b rotatably mounted on the mounting plate 101 and provided on the rotating disk 304a, and a gear 304c provided on the rotating column 304b and for engaging the rack 303c. Referring to fig. 6 to 8, when the rotating disc 304a rotates, the gear 304c is driven to rotate by the rotating column 304b, so that the rack 303c meshed with the gear 304c is driven to move up and down, thereby achieving the purpose of moving the lifting column 303a up and down. The clamping plate 303b can drive the linkage column 302 to move up and down together when the lifting column 303a moves up and down.

The adjusting lever unit 3 further includes a stopper portion 305 provided on the rotating column 304 b; the mounting board unit 1 further includes a stopper groove 104 provided on the mounting board 101 and configured to engage the stopper portion 305. The stopper portion 305 is inserted into the stopper groove 104, and the rotation post 304b is prevented from rotating, so that the position of the guide wheel 201 is kept fixed.

The stopper portion 305 includes a stopper 305a engaged with the stopper groove 104, a pressing post 305b for adjusting the position of the stopper 305a, and a stopper spring 305c for pushing up the stopper 305 a. Referring to fig. 9-10, when the push post 305b is not operated, the stopper 305a is caught in the stopper groove 104 by the stopper spring 305c. The operator can move the pressing post 305b inward by pressing the post 305b, and thus, the operator is out of engagement with the stopper groove 104, thereby unlocking the rotation post 304 b.

The stopper portion 305 further includes a retraction groove 305d provided on the stopper 305a, and a retraction block 305e provided on an inner end of the push post 305b for inwardly pulling the retraction groove 305 d. Referring to fig. 9-10, when the pressing post 305b is pressed inward, the retraction block 305e at the inner end thereof can press the retraction groove 305d inward, thereby moving the pressing post 305b inward out of engagement with the limiting groove 104.
