[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] The present utility model will be further described in detail below with reference to the accompanying drawings:

[0021] As Figure 1 and Figure 2 shown, a rope-out protection device for a wire rope according to the present utility model includes: a lower support plate 1, an upper support plate 2, and a protection pulley 3;

[0022] The lower support plate 1 is fixed at the rope-out position of the wire rope. An out-rope hole 11 is provided at the center of the lower support plate 1, and four groups of upper support plates 2 are fixed on the lower support plate 1;

[0023] The four groups of upper support plates 2 are respectively and symmetrically fixed around the out-rope hole 11. A protection pulley 3 is installed on each group of upper support plates 2, and the wheel grooves of the four groups of protection pulleys 3 together form a "mouth"-shaped structure surrounding the out-rope hole 11.

[0024] In this embodiment, by arranging protection pulleys 3 in multiple directions at the rope-out position of the wire rope, rolling friction is generated between the wire rope and the protection rollers during the up-and-down pulling process of the wire rope through the out-rope hole 11, reducing the loss degree of the wire rope, extending the service life of the wire rope, and at the same time being able to meet the requirements of the wire rope moving in different directions during complex operations, improving the safety of the wire rope during operation.

[0025] Specifically, when the load borne by the wire rope is large and the wire rope needs to swing up and down frequently, the protection pulley 3 directly contacts the wire rope and rolls simultaneously with the up-and-down pulling of the wire rope, converting sliding friction into rolling friction to reduce the friction coefficient of the wire rope and the wear degree of the wire rope.

[0026] Furthermore, protection pulleys 3 are arranged around the out-rope hole 11, and effective rolling support can be provided for the wire rope during the pulling process in different directions after the wire rope is pulled out through the out-rope hole 11, meeting the requirements of the wire rope moving in different directions during complex operations.

[0027] Among them, a fixing hole 12 is also provided on the lower support plate 1, and the lower support plate 1 is fixed on the workbench surface through bolts.

[0028] In the above embodiment, preferably, each group of upper support plates 2 includes two upper support plates 2 arranged in parallel with each other. The upper support plate 2 is perpendicular to the lower support plate 1, and the axis of the protection pulley 3 is perpendicular to the plate surface of the upper support plate 2.

[0029] During implementation, the two upper support plates 2 arranged in parallel with each other can also adopt an integrated "U"-shaped structure, and the two upper support plates 2 on both sides are connected inward by the same connecting plate, that is, the two upper support plates 2 and the connecting plate form an integrated structure, which can improve the installation stability of the protection pulley 3.

[0030] In the above embodiments, preferably, the upper support plate 2 is an L-shaped plate, the straight plate is perpendicular to the bottom plate, the bottom plate is fixed on the plate surface of the lower support plate 1, and the protection pulley 3 is installed on the straight plate.

[0031] During the implementation process, for the same group of upper support plates 2, the bottom plates extend vertically and outwardly from the bottom of the straight plate surfaces of the two upper support plates 2 respectively, so that the straight plate surfaces of the upper support plates 2 form a stable support relative to the lower support plate 1, improving the installation stability of the protection pulley 3 and enhancing the supporting force of the protection pulley 3 on the steel wire rope.

[0032] In the above embodiments, preferably, for the upper support plate 2 that is an L-shaped plate, there are the following three ways to set the straight plate and the bottom plate on its adjacent side upper support plate 2:

[0033] (1) Among two groups of adjacent upper support plates 2, the straight plate edge and the bottom plate edge of the adjacent side upper support plate 2 are welded and fixed to each other, that is, the straight plate edges of the adjacent side upper support plates 2 are aligned and welded, and the bottom plate edges are aligned and welded to form a stable connection structure.

[0034] (2) Among two groups of adjacent upper support plates 2, the adjacent side upper support plates 2 adopt the same bottom plate and the straight plate edges are welded and fixed, that is, the adjacent side upper support plates 2 adopt the same bottom plate, the straight plates on the adjacent sides are located on the adjacent right-angled sides of the bottom plate, and the edges of the straight plates are aligned and welded to form a stable connection structure.

[0036] In the above embodiments, preferably, the rope outlet hole 11 is a square structure, and the groove surface of the wheel groove of the protection pulley 3 is flush with the edge of the rope outlet hole 11 in the vertical direction, so that the protection pulley 3 can effectively support the steel wire rope.
