Description

Technical Field

[0001] The utility model belongs to the technical field of load hanging elements of winches or pulleys, and particularly relates to a rope pressure regulating device and a transport winch for stainless steel wire ropes. Background Art

[0002] The winch is currently the main equipment for installation and transportation at the mining and excavation working face of coal mines. Improving transportation efficiency is the key to tunnel transportation. However, due to the influence of geological conditions, there are many ups and downs and turns in underground tunnels, which greatly limits the use of the current winch. In order to prevent the pressure wheel from hanging in the air and leaving the track during the left and right turning of the wire rope, the current pressure wheel structure is relatively simple, and the pressure wheels are staggered up and down. At this time, the part of the pressure wheel that contacts the stainless steel wire rope cannot be completely fitted with the stainless steel wire rope during the left and right turning process, and greater friction is generated between the fitted parts, which will damage the wire rope and the pressure wheel and shorten their service life.

[0003] Therefore, a rope pressure adjustment device and a transport winch for stainless steel wire rope are designed to solve the technical problem in the prior art that the pressure wheel cannot fully fit with the wire rope during the left and right turning process of the wire rope, resulting in large friction.

[0004] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

[0064] Research has found that due to the influence of geological conditions, there are many ups and downs and turns in underground tunnels, which greatly limits the use of current winches. In order to prevent the pressure wheel from being suspended in the air and leaving the track during the left and right turns of the wire rope, the current pressure wheel structure is relatively simple, and the pressure wheels are staggered up and down. At this time, the part of the pressure wheel that contacts the stainless steel wire rope cannot be completely fitted with the stainless steel wire rope during the left and right turns, and greater friction is generated between the fitted parts, which will damage the wire rope and the pressure wheel and shorten their service life.

[0065] Based on the above research, an embodiment of the present disclosure provides a rope pressure adjustment device and a transport winch for stainless steel wire rope. The device is provided with an adjustment mechanism. In the process of the pressure wheel driving the winch to move, when the pressure wheel contacts the left and right turning points on the stainless steel wire rope, the adjustment mechanism is used to synchronously drive the pressure wheel to deflect to the left and right, so that the pressure wheel and the surface of the stainless steel wire rope always maintain contact, avoiding large friction between the two.

[0066] The defects in the above solutions are the results obtained by the utility model inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article should be the contributions made by the utility model inventor to the present invention during the disclosure process.

[0067] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0068] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0069] In some embodiments, as Figure 1 and Figure 1aAs shown, the stainless steel wire rope 4 is passed under the pressing wheel 2 so that the central concave portion of the pressing wheel 2 is in contact with the outer wall of the stainless steel wire rope 4. At this time, the pressing wheel 2 rolls on the surface of the stainless steel wire rope 4, driving the components connected to it to move. When the pressing wheel 2 moves to the right bend of the stainless steel wire rope 4, as seen from a top view ( Figure 1a As shown in the upper half of the figure, the stainless steel wire rope 4 applies a lateral pressure F1 to the upper right corner of the pressure wheel 2, forcing the pressure wheel 2 to deflect toward the right. Since the telescopic rod 21 and the sliding block 104 on the connecting member 100 are connected by a universal ball, the left end of the telescopic rod 21 deflects around the universal ball, and the right end of the telescopic rod 21 slides along the guide direction of the inclined groove 111 ( Figure 1a As shown in the lower half of the figure, the pressing wheel 2 is driven to deflect to the right synchronously, and at the same time, the inner concave part of the outer wall is tilted toward the right-turning part of the stainless steel wire rope 4, so as to ensure that the pressing wheel 2 is always in contact with the stainless steel wire rope 4, while reducing the lateral pressure generated by the stainless steel wire rope 4 on the pressing wheel 2, reducing the lateral friction between the two, and prolonging the service life of the pressing wheel 2 or the stainless steel wire rope 4;

[0070] Among them, when the telescopic rod 21 tends to deflect horizontally to the right, the left end of the telescopic rod 21 will move up so that the central concave part of the outer wall of the pressure wheel 2 is tilted toward the right turn of the stainless steel wire rope 4. At this time, the sliding block 104 slides upward in the slide groove 106 and the limit spring 105 is stretched to adapt to the vertical tilt generated by the telescopic rod 21.

[0071] In some embodiments, as Figure 1 and 2 As shown, when the pressure wheel 2 moves to the left turning point of the stainless steel wire rope 4, from a top view ( Figure 1b As shown in the upper half of the figure), the stainless steel wire rope 4 applies a lateral pressure F2 to the upper left corner of the pressure wheel 2, forcing the pressure wheel 2 to deflect toward the left. At this time, the left end of the telescopic rod 21 pushes the connecting member 100 to deflect through the sliding block 104 during the deflection process, thereby driving the plug-in rod 102 to deflect around the bearing connection between it and the base 101, that is, the elastic reset bearing 103 rotates to adapt to the left deflection trend generated by the telescopic rod 21. At this time, in order to adapt to the central concave part of the outer wall of the pressure wheel 2 to tilt toward the left turn of the stainless steel wire rope 4, the reset spring 114 rebounds to generate a lateral thrust F3, pushing the clamping member 110 and the sliding member 112 to slide on the sliding seat 113 close to the stainless steel wire rope 4.

[0072] In some embodiments, as Figure 3 As shown, in order to enable the numerous pressing wheels 2 to better clamp the stainless steel wire rope 4, the adjacent pressing wheels 2 are staggered up and down, so that each pressing wheel 2 can better clamp the stainless steel wire rope 4.

[0073] On the other hand, the embodiment of the present disclosure also provides a transport winch for stainless steel wire rope, including: a load-bearing plate 5, the upper end surface of which is connected to the base 101 and the lower end surface of the sliding seat 113, wherein a loading plate 3 is hoisted below the load-bearing plate 5 to load the transported materials, and a plurality of rope pressure adjustment devices 1 as described above are arranged above the load-bearing plate 5.

[0074] In the description of the embodiments of the present invention, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0075] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, terms such as "first", "second" and other numerical terms do not imply an order or sequence when used herein unless expressly indicated above. Therefore, without departing from the teachings of the example embodiments, the first element, component, region, layer or section discussed above may be referred to as a second element, component, region, layer or section.

[0076] Spatially relative terms, such as "inside," "outside," "below," "beneath," "down," "above," "on," etc., may be used herein to describe the relationship of one element or feature to another element or feature as illustrated in the figures. In addition to the orientations depicted in the figures, spatially relative terms may be intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as being "below" or "below" other elements or features will be oriented to be "above" the other elements or features. Thus, the example term "below" may encompass both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0077] In the above discussion, unless otherwise indicated, the terms "about," "approximately," "substantially," etc., when used to describe a numerical value, mean a variation of + / - 10% of the value.

[0078] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
