Detailed Description

To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

The winding drum is an important part of crane equipment and is used for winding, unwinding and storing steel wire ropes. Due to the limitation of the diameter of the winding drum and the effective length of the rope grooves, when the length of the steel wire rope is too long, two or more layers of winding can be selected for storage on the winding drum, so that the size and the weight of the winding drum can be reduced. For the reel of two-layer wire rope of winding, can install rope climbing piece on the reel usually, make wire rope transition from the first layer to the second floor through rope climbing piece direction to guarantee the orderly winding and the emission of wire rope on the reel.

Fig. 1 is a schematic structural diagram of a climbing rope block provided by the related art. As shown in fig. 1, the rope climbing block 5 is in a shape of surrounding the winding drum 4, the rope climbing block 5 is mounted in front of the winding drum 4 in a surrounding manner, and the rope climbing block 5 is in a quadrangular shape. The rope climbing block 5 illustrated in fig. 1 has a first end 51 of smaller width and a second end 52 of larger width. The rope climbing block 5 comprises a first end 51 surface and a second end 52 surface which are parallel to each other after being unfolded, wherein the first end 51 surface is an end surface of the first end 51, and the second end 52 surface is an end surface of the second end 52.

As shown in fig. 1, a first side 53, a second side 54, a third side 55 and a fourth side 56 are sequentially arranged between the first end 51 and the second end 52, the first side 53 and the third side 55 are oppositely arranged, the side of the third side 55 connected with the second end 52 is inclined to the first side 53, the slope of the third side 55 is consistent with the slope of the rope groove line of the winding drum 4, the second side 54 and the fourth side 56 are oppositely arranged, the side of the second side 54 connected with the first end 51 is inclined to the fourth side 56, and the included angle between the first side 53 and the fourth side 56 is a right angle.

Fig. 2 is a schematic view of a state that a climbing rope block provided by the related art is assembled with a winding drum. As shown in fig. 2, when the rope climbing block 5 is assembled, the first side surface 53 is attached to the non-rope-entering end web 41 of the winding drum 4, and the fourth side surface 56 is attached to the outer surface of the drum body of the winding drum 4. The third side 55 is in abutment with the steel cord 6 when guiding the steel cord 6 from the first layer to the second layer. It can be seen that the more accurate the positioning of the rope climbing block 5 on the winding drum 4, the more regular the winding of the steel wire rope 6.

The related art will usually use the climbing block 5 and the outer web of the drum 4 as positioning references, since there may be manufacturing errors in the climbing block 5 and also processing errors in the outer web of the drum 4. Therefore, once the positioning accuracy of the positioning tool and the manufacturing accuracy of the rope climbing block 5 are not guaranteed, the positioning of the rope climbing block 5 is deviated, the phenomenon of rope disorder of the steel wire rope 6 is caused, and the normal work of the crane is seriously influenced.

In order to improve the positioning accuracy of the rope climbing block 5 on the winding drum 4, the embodiment of the disclosure provides a positioning method of the rope climbing block 5. Fig. 3 is a flowchart of a positioning method of a rope climbing block according to an embodiment of the disclosure. As shown in fig. 3, the positioning method includes:

step S1: and acquiring a first width and a second width of the rope climbing block 5.

Wherein, the first width is the minimum width of the rope climbing block 5 in the axial direction of the winding drum 4, and the second width is the maximum width of the rope climbing block 5 in the axial direction of the winding drum 4.

Referring to fig. 1, the first width is the width of the first end 51 of the rope climbing block 5, and the second width is the width of the second end 52 of the rope climbing block 5.

Step S2: a first boundary line L1 and a second boundary line L2 are scribed on the outer peripheral wall of the roll 4 based on the first width and the second width.

The first boundary line L1 is a circumferential annular curve of the drum 4 having a first width from the non-rope-inlet end web 41, and the second boundary line L2 is a circumferential annular curve of the drum 4 having a second width from the non-rope-inlet end web 41.

Step S3: the positioning intersection points of the two ends of the rope climbing block 5 and the first boundary line L1 and the second boundary line L2 are determined by the positioning device.

Fig. 4 is a schematic structural diagram of a positioning device according to an embodiment of the present disclosure. As shown in fig. 4, the positioning device includes a positioning portion 1 and a positioning pin 2, the positioning pin 2 is vertically disposed on one side of the positioning portion 1, the positioning portion 1 is provided with a positioning slider 3, the positioning slider 3 is located on the other side of the positioning portion 1, which is far away from the positioning pin 2, and each positioning slider 3 has a positioning arc surface 31 matched with the arc surface of the rope groove 40 of the winding drum 4.

The distance between the positioning needle 2 and the center of the positioning arc surface 31 is D, and D is r + np. r is the radius of the steel wire rope 6 matched with the rope groove 40 of the winding drum 4, p is the pitch of the rope groove 40 of the winding drum 4, and n is a positive integer greater than or equal to 1.

Step S4: the first positioning line L3 and the second positioning line L4 are determined based on the positioning intersections.

Step S5: the rope climbing block 5 is positioned according to the first positioning line L3 and the second positioning line L4.

When the rope climbing block 5 is positioned, firstly, a first width and a second width of the rope climbing block 5 are obtained, namely, the maximum width and the minimum width of the end part of the rope climbing block 5 are determined; when the rope climbing block 5 is installed on the winding drum 4, one side wall of the rope climbing block 5 is attached to the non-rope-inlet end web plate 41 of the winding drum 4, so that after the maximum width and the minimum width of the end part of the rope climbing block 5 are determined, a first boundary line L1 circumferentially surrounding the winding drum 4 is scribed at the position, away from the minimum width of the non-rope-inlet end web plate 41, on the winding drum 4, and a second boundary line L2 circumferentially surrounding the winding drum 4 is scribed at the position, away from the maximum width of the non-rope-inlet end web plate 41, on the winding drum 4; that is, the determined first boundary line L1 may serve as a side wall boundary of the smaller end portion of the rope block 5, and the determined second boundary line L2 may serve as a side wall boundary of the larger end portion of the rope block 5, thereby accurately positioning the installation position of the rope block 5 in the axial direction of the winding drum 4.

Then, the positioning intersections of both ends of the rope block 5 with the first boundary line L1 and the second boundary line L2 are climbed using the positioning means. Wherein, positioner includes location portion 1 and pilot pin 2, and the homonymy of locating plate 12 is equipped with pilot pin 2 and location slider 3, because the location cambered surface 31 of location slider 3 is with the grooving 40 cambered surface phase-match of reel 4, and positioner can install in the grooving 40 of reel 4 through location slider 3 promptly. And the distance D between the positioning needle 2 and the center of the positioning arc surface 31 is r + np, r is the radius of the steel wire rope 6 matched with the rope groove 40 of the winding drum 4, and p is the pitch of the rope groove 40 of the winding drum 4. Because the side wall of the rope climbing block 5, which faces away from the non-rope-entering end web plate 41, is always tightly attached to the steel wire rope 6 in the use process of the rope climbing block 5, the distance D between the positioning needle 2 and the center of the positioning arc surface 31 is equal to the sum of the radius of the steel wire rope 6 and the pitch of at least one rope groove 40 of the winding drum 4, that is, the number of the steel wire ropes 6 between the positioning needle 2 and the rope groove 40 of the winding drum 4 is an integer. Therefore, after the positioning device is installed in the rope groove 40 of the winding drum 4, the position of the positioning needle 2 is the area on the outer surface of the steel wire rope 6 closest to the non-rope-inlet end web 41. At this time, the positioning needle 2 intersects the first boundary line L1 and the second boundary line L2 by adjusting the position of the positioning device in the rope groove 40 of the drum 4, and the positioning intersection point is obtained. The position of the positioning intersection point is the position of the end surfaces of the two ends of the rope climbing block 5 on the circumferential direction of the winding drum 4, so that the mounting positions of the two ends of the rope climbing block 5 on the winding drum 4 are accurately positioned.

Then, after the positioning intersection points are determined, because the end surfaces of the two ends of the climbing rope block 5 are perpendicular to the non-rope-entering end web plate 41, the first positioning line or the second positioning line L4 can be determined according to the perpendicular line passing through each positioning intersection point and the non-rope-entering end web plate 41, and thus the installation positions of the two ends of the climbing rope block 5 on the winding drum 4 can be more accurately positioned through the positioning distance adjustment of the first positioning line L3 and the second positioning line L4 and the end surfaces of the two ends of the climbing rope block 5.

Compared with the prior art, the positioning climbing rope block 5 does not need to be used for assisting in positioning the climbing rope block 5 in the embodiment of the disclosure, and the positioning device adopted is matched with the rope groove 40 of the winding drum 4 to ensure the positioning precision instead of using the outer web plate of the winding drum 4 as the positioning reference, so that the positioning accuracy is higher, the climbing rope block 5 can be accurately positioned and installed on the winding drum 4, the phenomenon that the steel wire rope 6 is in disorder is prevented, and the crane can work efficiently.

Fig. 5 is a schematic view of a usage state of a winding drum provided by an embodiment of the disclosure. As shown in fig. 5, in conjunction with the step S2, a specific process of scribing the first boundary line L1 and the second boundary line L2 in the embodiment of the disclosure may include:

as shown in fig. 5, a first boundary line L1 surrounding the reel 4 is scribed on the outer peripheral wall of the barrel of the reel 4 at a position spaced from the non-rope-entering end web 41 by a first width.

As shown in fig. 5, a second boundary line L2 of the reel 4 is defined on the outer peripheral wall of the drum body of the reel 4 at a position spaced apart from the non-rope-entering end web 41 by a second width.

Alternatively, the determination of the positioning intersections of the both ends of the rope block 5 with the first boundary line L1 and the second boundary line L2 using the positioning means in step S3 may include the steps of:

in a first step, the positioning device is mounted in the rope groove 40 of the drum 4.

In a first step, fig. 6 is a schematic structural diagram of an assembly of a positioning device and a winding drum provided by an embodiment of the present disclosure. As shown in fig. 6, the positioning pin 2 is placed in the rope groove area of the winding drum 4, and the distance between the positioning pin 2 and the rope inlet end web 41 is controlled to be not less than the second width, so that when the positioning device is subsequently controlled to slide along the extending direction of the rope groove 40 of the winding drum 4, the positioning pin 2 can intersect the second boundary line L2 and the first boundary line L1. Then, the positioning part 1 is pressed, so that the positioning arc surface 31 of the positioning slide block is tightly attached to the arc surface of the rope groove 40 of the winding drum 4, and no large error occurs in positioning.

In a second step, the positioning device is controlled to slide along the extension direction of the rope groove 40 of the winding drum 4.

In the second step, the control can hold the positioning part 1 of the positioning device by hand and press the positioning part 1, so that the positioning slide block 3 is tightly attached to the cambered surface of the rope groove 40 of the winding drum 4. At the same time, the positioning part 1 is pushed to slide along the extending direction of the rope groove 40 of the winding drum 4, namely, the positioning device is controlled to slide around the circumferential direction of the drum body of the winding drum 4, and the positioning needle 2 of the positioning device also slides along with the positioning needle.

Thirdly, if the positioning needle 2 slides to intersect with the first boundary line L1, determining the intersection point of the positioning needle 2 and the first boundary line L1 as a first positioning intersection point A1; if the pilot pin 2 slides to intersect the second boundary line L2, the intersection of the pilot pin 2 and the second boundary line L2 is determined as a second pilot intersection a 2.

In a third step, the tip of the positioning pin 2 gradually approaches the second boundary line L2 in the area of the cordless slot of the reel 4 as the positioning device continues to slide on the reel 4. As shown in fig. 7, when the positioning pin 2 slides to the second boundary line L2, the positioning pin 2 and the second boundary line L2 meet each other. The point of intersection is marked and the point of intersection of the needle 2 and the second boundary line L2 is determined as a second positioning intersection a 2.

Subsequently, the positioning device is further controlled to slide on the reel 4, and the tip of the positioning pin 2 gradually approaches the first boundary line L1 in the cordless slot region of the reel 4. As shown in fig. 8, when the positioning pin 2 slides onto the first boundary line L1, the positioning pin 2 and the first boundary line L1 meet each other. The intersection is marked, and the intersection of the positioning pin 2 and the first boundary line L1 is determined as a first positioning intersection a 1.

Alternatively, the determining of the first positioning line L3 and the second positioning line L4 based on the positioning intersections in the step S4 may include the steps of:

in the first step, as shown in fig. 8, a first perpendicular line is drawn to the non-entry end web 41 based on the first positioning intersection point a1, and a third positioning intersection point A3 of the first perpendicular line and the non-entry end web 41 is obtained.

In the second step, a line connecting the first positioning intersection a1 and the third positioning intersection A3 is determined as a first positioning line L3.

Since the end surfaces of the two ends of the rope climbing block 5 are perpendicular to the non-rope-entering end web plate 41, a connecting line between the intersection point of the first perpendicular line and the non-rope-entering end web plate 41 and the first positioning intersection point a1 is inevitably overlapped with the orthographic projection of the end surface of the first end 51 of the rope climbing block 5 on the winding drum 4. Namely, the first positioning line L3 can be used as a reference line of the first end 51 of the rope climbing block 5. Thereby accurately locating the mounting position of the first end 51 of the rope climbing block 5 on the winding drum 4.

Thirdly, as shown in fig. 7, a second perpendicular is drawn to the non-rope-entering end web plate 41 based on the second positioning intersection point a2, and a fourth positioning intersection point a4 of the second perpendicular and the non-rope-entering end web plate 41 is obtained.

Fourthly, a connecting line of the second positioning intersection point A2 and the fourth positioning intersection point A4 is determined as a second positioning line L4.

Since the end surfaces of the two ends of the rope climbing block 5 are perpendicular to the non-rope-entering end web plate 41, the connecting line of the intersection point of the second perpendicular line and the non-rope-entering end web plate 41 and the second positioning intersection point a2 is necessarily coincident with the orthographic projection of the end surface of the second end 52 of the rope climbing block 5 on the winding drum 4. Namely, the second positioning line L4 can be used as a reference line of the second end 52 of the rope climbing block 5. Thereby accurately locating the mounting position of the second end 52 of the rope climbing block 5 on the winding drum 4.

Alternatively, the positioning of the rope block 5 according to the first positioning line L3 and the second positioning line L4 in the step S5 may include the steps of:

firstly, one side surface of the rope climbing block 5 is attached to the inner wall of the web plate at the non-rope-entering end.

With reference to fig. 1, the first step includes attaching the first side surface 53 of the rope climbing block 5 to the inner wall of the non-rope-entering end web, and attaching the fourth side surface 56 of the rope climbing block 5 to the outer surface of the drum body of the winding drum 4.

In the second step, the first end 51 of the climbing rope block 5 is controlled to be flush with the first positioning line L3, and the second end 52 of the climbing rope block 5 is controlled to be flush with the second positioning line L4.

In the second step, the end face of the first end 51 of the rope climbing block 5 is aligned with the first positioning line L3 on the winding drum 4, and the end face of the second end 52 of the rope climbing block 5 is aligned with the second positioning line L4 on the winding drum 4, that is, the two ends of the rope climbing block 5 are accurately positioned at the position, to be assembled, of the winding drum 4.

In the embodiment of the present disclosure, after step S5, a step of fixing the rope climbing block 5 on the winding drum 4 may be further included, and the specific fixing process may include the following steps:

firstly, spot welding is adopted to position the position of a first positioning line L3 between the rope climbing block 5 and the winding drum 4, the position of a second positioning line L4 between the rope climbing block 5 and the winding drum 4, the rope climbing block 5 and the non-rope-entering end web plate 41.

In the first step, through spot welding, form the solder joint between climbing rope piece 5 and reel 4 and the contact surface of non-income rope end web 41 to quick fixed avoids in the follow-up welding process, climbing rope piece 5 is not hard up.

And secondly, welding gaps between the rope climbing block 5 and the non-rope-entering end web plate 41 and between the rope climbing block 5 and the winding drum 4.

As shown in fig. 4, the positioning portion 1 includes a positioning bar 11 and a positioning plate 12, one end of the positioning bar 11 is connected to one side of the positioning plate 12, the positioning pin 2 is connected to the other end of the positioning bar 11, and the positioning slider 3 is located on the plate surface of the positioning plate 12.

In the above implementation manner, the positioning strip 11 is used for installing the positioning pin 2, and the positioning plate 12 is provided with the positioning slider 3. Because the positioning device relies on the positioning slider 3 to match with the rope groove 40 of the winding drum 4 to realize the positioning of the positioning device, the part of the positioning slider 3 arranged on the positioning part 1 is set as the positioning plate 12, the positioning slider 3 with larger volume can be arranged in enough area, so that the area of the positioning arc surface 31 of the positioning slider 3 is increased, the contact area between the positioning slider 3 and the rope groove 40 of the winding drum 4 is larger, and the positioning accuracy of the positioning device on the rope groove 40 of the winding drum 4 is ensured.
