[0037] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a specific embodiment of the first aspect of the utility model provides a hoisting device. The hoisting device includes a drum 100, a pressing member 200 and a fastener 300;

[0038] The reel 100 includes a roller 110 and two end plates 120; the two end plates 120 are respectively arranged at the two ends of the roller 110 in a one-to-one correspondence; the first end plate 120 is provided with a through hole 121. The pressing member 200 is arranged on the side of the first end plate 120 away from the roller 110, and a clamping hole is formed between the pressing member 200 and the first end plate 120. The head of the fastener 300 is limitedly connected with the through hole 121, and the tail of the fastener 300 passes through the through hole 121 and is connected with the pressing member 200, so as to press the pressing member 200 toward the first end plate 120.

[0039] In a specific embodiment of the utility model, by opening a through hole 121 on the first end plate 120, when installing the clamping member 200, it can be installed from the inner side of the first end plate 120. Specifically, the tail of the fastener 300 passes through the through hole 121 and is connected to the clamping member 200, and the head of the fastener 300 is limitedly connected to the through hole 121, thereby pressing the clamping member 200 toward the first end plate 120, so that the relative position of the end of the wire rope and the first end plate 120 is fixed. Compared with the solution of installing from the outside of the first end plate 120, this embodiment can reduce the installation space outside the end plate 120, and even does not need to reserve installation space outside the end plate 120, thereby increasing the length of the drum 110, increasing the number of rope grooves on the drum 110, and increasing the rope capacity of the drum 100. When the length of the wire rope is the same, the number of layers of the wire rope wound on the drum 110 can be reduced, reducing the risk of rope disorder. In addition, this embodiment uses the inner space of the end plate 120 as the installation space, which improves the installation efficiency and reduces the difficulty of later maintenance of the pressing member 200.

[0040] It can be understood that the inner side of the end plate 120 refers to the side of the end plate 120 facing the drum 110 , and the outer side of the end plate 120 refers to the side of the end plate 120 facing away from the drum 110 .

[0041] It is understandable that a through hole 121 may be provided on the second end plate 120 to form a clamping hole between the pressing member 200 and the second end plate 120. The tail of the fastener 300 passes through the through hole 121 and is connected to the pressing member 200 to press the pressing member 200 against the second end plate 120.

[0042] In some embodiments, the drum 110 is coaxially arranged with the two end plates 120, and the cross-sections of the end plates 120 and the drum 110 perpendicular to the central axis are both circular. The diameter of the end plate 120 is larger than the diameter of the drum 110, and the two end plates 120 and the outer surface of the drum 110 form a steel wire rope cavity. In this embodiment, because the fastener 300 passes from the inner side of the end plate 120 to the outer side of the end plate 120 to install the pressing member 200 on the outer side of the end plate 120, the steel wire rope cavity is also equivalent to the installation space of the fastener 300, which improves the installation efficiency, avoids reserving installation space on the outer side of the end plate 120, increases the length of the drum 110, increases the number of rope grooves on the drum 110, and increases the rope capacity of the drum 100.

[0043] like Figure 1 As shown, in a specific embodiment of the present invention, a groove 122 is formed on the side of the first end plate 120 facing the drum 110, the through hole 121 is located in the groove 122, and the head of the fastener 300 is sunk into the groove 122. By providing the groove 122 and the head of the fastener 300 being sunk into the groove 122, the head of the fastener 300 can be prevented from protruding from the side of the end plate 120 facing the drum 110, thereby avoiding affecting the winding and release of the wire rope and reducing the risk of damage to the wire rope.

[0044] In some embodiments, the number of the grooves 122 may be one or at least two. It is understandable that the number of the grooves 122 is not limited in the specific embodiments of the present invention.

[0045] Optionally, the two grooves 122 are arranged along the circumference of the end plate 120 .

[0046] In some embodiments, the cross section of the groove 122 perpendicular to the central axis of the drum 110 is square, rectangular, circular or arc-shaped, etc. It can be understood that the shape of the groove 122 is not limited in this embodiment.

[0047] In a specific embodiment of the present invention, the pressing member 200 is provided with a threaded hole 210, and the tail of the fastener 300 is threadedly matched with the threaded hole 210. By providing the threaded hole 210 on the fastener 300, the use of a nut can be avoided, eliminating the waste of space caused by the use of a nut.

[0048] Optionally, when the fastener 300 is assembled in the threaded hole 210, the tail end of the fastener 300 is located in the threaded hole 210. In other words, the fastener 300 does not leak out of the threaded hole 210, thereby avoiding the tail end of the fastener 300 from occupying the installation space outside the end plate 120 and eliminating the space waste caused by the tail end of the fastener 300.

[0049] like Figure 3 As shown, in some embodiments, the number of threaded holes 210 is two, and the two threaded holes 210 are respectively arranged on both sides of the clamping hole in a one-to-one correspondence. In other embodiments, the number of threaded holes 210 is greater than two, and threaded holes 210 are arranged on both sides of the clamping hole to improve the installation stability of the clamping member 200 and the end plate 120.

[0050] In a specific embodiment of the present invention, the fastener 300 includes a bolt; the head of the bolt is sunk into the groove 122, and the screw of the bolt is threadedly matched with the threaded hole 210. The bolt can be purchased, which reduces the cost of the hoisting equipment.

[0051] Optionally, when the screw is screwed into the threaded hole 210, the end of the screw away from the head is located inside the threaded hole 210, avoiding occupying the installation space outside the end plate 120 and eliminating space waste.

[0052] In a specific embodiment of the utility model, the first end plate 120 is provided with at least two through holes 121, and the through holes 121 correspond one-to-one to the threaded holes 210. The two through holes 121 are respectively arranged on both sides of the clamping hole along the radial direction of the end plate 120, which can improve the installation stability of the clamping piece 200 and the first end plate 120.

[0053] In some embodiments, four through holes 121 are disposed in each groove 122 , and each two through holes 121 form a group. The two groups of through holes 121 are respectively arranged on both sides of the clamping hole along the radial direction of the first end plate 120 ; the same group of through holes 121 is arranged along the circumference of the first end plate 120 .

[0054] like Figure 2 and Figure 3As shown, in a specific embodiment of the present invention, the pressing member 200 is provided with a first pressing groove 220; the first end plate 120 is provided with a second pressing groove 123; the first pressing groove 220 and the second pressing groove 123 are combined to form a clamping hole. By providing the first pressing groove 220, the contact area between the pressing member 200 and the wire rope can be increased, ensuring that the relative position of the wire rope and the end plate 120 is fixed, and increasing the stability of the wire rope.

[0055] like Figure 2 As shown, in a specific embodiment of the present invention, the second pressing groove 123 extends along the circumference of the first end plate 120 , which can ensure that the steel wire rope can be smoothly wound and released by the drum 110 .

[0056] In some embodiments, the end plate 120 is provided with a rope outlet hole 124 , which is located at one end of the second pressing groove 123 . After one end of the wire rope passes through the rope outlet hole 124 , it is placed in the second pressing groove 123 .

[0057] Furthermore, the rope outlet hole 124 is arranged to be inclined, and the inclination direction is consistent with the extension direction of the wire rope, so that one end of the wire rope can pass through the rope outlet hole 124 to ensure that the drum 110 can smoothly wind or release the wire rope.

[0058] like Figure 3 As shown, in a specific embodiment of the present invention, the pressing member 200 includes a pressing block; the cross section of the pressing block perpendicular to the central axis of the roller 110 is rectangular, which is easy to process and reduces the difficulty and cost of processing.

[0059] In some embodiments, the cross section of the pressing block perpendicular to the central axis of the drum 110 is arc-shaped, which can increase the contact area between the pressing block and the steel wire rope, so that the steel wire rope is clamped more firmly in the clamping hole.

[0060] Preferably, the cross section of the pressing block perpendicular to the central axis of the drum 110 is square.

[0061] It is understandable that in the specific embodiment of the present invention, there is no limitation on the shape of the cross section of the pressing block perpendicular to the central axis of the drum 110 .

The drum 110 is used to wind or release the wire rope.

[0063] Optionally, after one end of the wire rope passes through the rope outlet hole 124, it is placed in the second pressing groove 123, and then the clamping piece 200 is installed on the outer side of the first end plate 120, so that the first pressing groove 220 corresponds to the second pressing groove 123 to form a clamping hole, and the end of the wire rope is located in the clamping hole; finally, the tail of the fastener 300 is inserted into the through hole 121 from the inner side of the first end plate 120, and is screwed into the threaded hole 210 of the clamping piece 200, so that the clamping piece 200 is pressed toward the outer side of the end plate 120, and at the same time, the head of the fastener 300 is sunk into the groove 122 and is located outside the through hole 121 to limit the through hole 121.

[0064] like Figure 4 and Figure 5 As shown, in a specific embodiment of the present invention, the hoisting device further includes a hoisting frame 400; the hoisting frame 400 forms an installation space, and the drum 100 is located in the installation space and connected to the hoisting frame 400. The hoisting frame 400 can protect the drum 100 and facilitate the installation of the drum 100 on different types of operating machines, thereby expanding the scope of application.
