[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.
[0024] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0025] See also Figure 1 , Figure 2 and Figure 3 On the one hand, the embodiment of the utility model provides an anti-slip groove device 7, which is used to cooperate with the wire rope drum 6 to limit the position of the wire rope, including a first seat body 1, a second seat body 2, a pin 5, a locking member and a limiting roller 3. The first seat body 1 is provided with a plug hole extending along the first direction, and the second seat body 2 is inserted into the plug hole. Along the first direction, the first seat body 1 is provided with a plurality of pin holes 4 at intervals, and the pin holes 4 are connected to the plug hole. The pin 5 is selectively inserted into the pin hole 4, and the second seat body 2 is against the pin 5. The locking member is used to lock the second seat body 2 to the first seat body 1, and the limiting roller 3 is rotatably connected to the second seat body 2.
[0026] The first direction may be the direction shown by the Z axis in the figure, and the first direction may be the vertical direction.
[0027] The second base body 2 is inserted into the insertion hole, so that the second base body 2 can move along the first direction relative to the first base body 1 .
[0028] The pin 5 is used to adjust the position of the second seat body 2 inserted into the socket, that is, when the pin 5 is inserted into different pin holes 4, when the second seat body 2 moves in the socket to abut against the pin 5, the position of the second seat body 2 relative to the first seat body 1 is different.
[0029] The second seat body 2 can be quickly limited by the pin 5, making the operation process more efficient and quick.
[0030] The limiting roller 3 is used to cooperate with the drum 6. The limiting roller 3 and the drum 6 are arranged parallel and spaced apart. When the wire rope passes between the limiting roller 3 and the drum 6, the risk of the wire rope radially jumping relative to the drum 6 can be reduced, thereby reducing the risk of the wire rope falling off the drum 6.
[0031] The first seat body 1 can be connected to the base of the crane or other fixed places, the limiting roller 3 is rotatably connected to the second seat body 2, and the second seat body 2 is movably connected to the first seat body 1, so that the position of the limiting roller 3 relative to the reel 6 can be adjusted.
[0032] See also Figure 2 In some embodiments, the locking member includes a supporting portion 8 , the first seat body 1 is provided with a threaded hole, the threaded hole is connected to the pin hole 4 , the supporting portion 8 is threadedly connected to the threaded hole, and the supporting portion 8 abuts against the second seat body 2 .
[0033] The abutting portion 8 is threadedly connected to the threaded hole, and the radial position of the abutting portion 8 relative to the threaded hole can be adjusted by rotating the abutting portion 8 .
[0034] When the abutting portion 8 rotates to abut against the second seat body 2, the second seat body 2 cannot move relative to the first seat body 1, thereby locking the second seat body 2. On the contrary, the abutting portion 8 rotates in the opposite direction, so that there is a gap between the abutting portion 8 and the second seat body 2, and the second seat body 2 can move relative to the first seat body 1.
[0035] See also Figure 3 In some embodiments, the second seat body 2 is clearance-matched with the insertion hole.
[0036] The second seat body 2 and the insertion hole are clearance-matched, so that the position of the second seat body 2 relative to the insertion hole can be adjusted, thereby facilitating fine-tuning the position of the limiting roller 3 relative to the reel 6 .
[0037] See also Figure 2 and Figure 3 In some embodiments, the second seat body 2 is against the inner wall of the socket on both sides along the second direction, and the second seat body 2 is gap-matched with the inner wall of the socket on both sides along the third direction. The second direction is parallel to the axial direction of the limiting roller 3, and the first direction, the second direction and the third direction are perpendicular to each other.
[0038] The second direction may be the direction shown by the X axis in the figure, the third direction may be the direction shown by the Y axis in the figure, the second direction and the third direction may be parallel to the horizontal plane.
[0039] The two sides of the second base body 2 along the second direction abut against the inner wall of the insertion hole, thereby improving the movement accuracy of the second base body 2 relative to the first base body 1 .
[0040] The two sides of the second seat body 2 along the third direction are gap-matched with the inner wall of the insertion hole, so that the second seat body 2 can move relatively in the insertion hole along the third direction, which is convenient for adjusting the position of the limiting roller 3 in the third direction.
[0041] See also Figure 1In some embodiments, along the axial direction of the limiting roller 3 , a first seat body 1 and a second seat body 2 are respectively provided on both sides of the limiting roller 3 .
[0042] Correspondingly, the first seat body 1 on both sides of the limiting roller 3 may be provided with a pin 5 and abutting portion 8 respectively.
[0043] A first seat body 1 and a second seat body 2 are respectively arranged on both sides of the limiting roller 3 , thereby improving the movement stability and movement accuracy of the limiting roller 3 .
[0044] In some embodiments, the number of the limiting rollers 3 is two, and the two limiting rollers 3 are arranged in parallel and spaced apart along a third direction, and the third direction is perpendicular to the first direction.
[0045] There are two limiting rollers 3, so that one anti-slip groove device 7 can cooperate with two reels 6. For example, the two reels 6 can be arranged in parallel and spaced apart, the anti-slip groove device 7 can be arranged between the two reels 6, and the two limiting rollers 3 cooperate with the two reels 6 respectively.
[0046] See also Figure 1 On the other hand, an embodiment of the utility model provides a crane, including at least one drum 6 for winding a wire rope, and also includes the anti-slip groove device 7 in the above embodiment, and the axis of the limiting roller 3 and the drum 6 are arranged parallel and spaced apart.

[0048] The anti-slip groove device 7 is provided with a plurality of them. On the one hand, the range of cooperation between the drum 6 and the anti-slip groove device 7 is increased, and the risk of the wire rope falling off is reduced. On the other hand, while ensuring the coverage of the anti-slip groove device 7, the number of the limiting rollers 3 of each anti-slip groove device 7 can be shorter, reducing the risk of the limiting rollers 3 being bent by force when the wire rope contacts the limiting rollers 3.
[0049] See also Figure 4 In some embodiments, between two adjacent anti-slip groove devices 7 , opposite sides of the limiting rollers 3 of the two anti-slip groove devices 7 share a first seat body 1 and a second seat body 2 .
[0050] Sharing the first seat body 1 and the second seat body 2 reduces the number of the first seat bodies 1 and the second seat bodies 2 required, thereby reducing the manufacturing cost of the crane.
[0051] In some embodiments, two anti-slip groove devices 7 are provided, and the limiting rollers 3 of the two anti-slip groove devices 7 are respectively arranged on both sides of the axial direction of the reel 6 .
[0052] The limiting rollers 3 are arranged on both sides of the axial direction of the drum 6, which reduces the number of anti-slip groove devices 7 required for the crane, saves costs and reduces the risk of the wire rope falling off the drum 6.
