Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy and hydropower, and in particular relates to a three-layer winding drum retaining ring for a gantry crane wire rope. Background Art

[0002] In water conservancy and hydropower projects, especially various hydraulic gate projects and pump station projects, gantry cranes are widely used to open and close gates and perform equipment maintenance. During the operation of the gantry crane, when the wire rope is wound to the inner side of the winding retaining edge, it should rise to the upper layer and continue to wind in the reverse direction.

[0003] When the existing drum on the gantry crane is used to wind the wire rope for lifting heavy objects, the two ends of the rope strands are usually fixed in the middle of the drum by a rope head pressure plate. When the first layer is wound, it is wound simultaneously on both sides of the drum. When the wire rope is wound to the outermost retaining ring of the drum, the retaining ring guides the wire ropes on both sides to start winding the second layer from the outside to the inside at the same time. When the second layer of wire rope is wound to the position of the rope head pressure plate, if the wire rope continues to be wound, it will be pressed on the rope head pressure plate, causing rope climbing. Since the heavy object is lifted below the wire rope, it is easy to be hurt and bent by the pressure plate; if the winding continues, the two strands of wire rope will be twisted together, causing damage to the wire rope, threatening equipment and personal safety;

[0004] In order to solve the above problems, the present application proposes a three-layer winding drum retaining ring for a gantry crane wire rope. Utility Model Content

[0025] 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1 As shown:

[0028] A three-layer winding drum retaining ring for a door crane wire rope comprises a fixed seat 1 and a drum body 5 rotatably connected above the fixed seat 1 , a motor 2 is arranged on the side of the fixed seat 1 , and an output end of the motor 2 is connected to the drum body 5 .

[0029] In the present embodiment: when the existing drum on the gantry crane winds the wire rope to lift heavy objects, the two ends of the rope strands are usually fixed in the middle of the drum by a rope end pressure plate, and the first layer is wound simultaneously on both sides of the drum. When the wire rope is wound to the outermost retaining ring of the drum, the retaining ring guides the wire ropes on both sides to start winding the second layer from the outside to the inside at the same time. When the second layer of wire rope is wound to the position of the rope end pressure plate, if the wire rope continues to be wound, it will be pressed onto the rope end pressure plate, causing rope climbing. Since the heavy object is lifted below the wire rope, it is easy to be hurt and bent and deformed by the pressure plate; if the winding continues, the two strands of wire rope will twist together, causing damage to the wire rope, threatening the equipment and personal safety; in terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a limit component 3 and a guide component 4 are added to the present application document.

[0030] More specifically:

[0031] like Figure 1-Figure 5 As shown:

[0032] In combination with the above content, the limiting assembly 3 includes two groups of fixed blocks 32 symmetrically arranged on the surface of the reel body 5 in a T-shaped structure, and baffles 31 are fixedly connected on both sides of the surface of the two groups of fixed blocks 32. The surface of the baffle 31 is rotatably connected to several groups of partitions 36 in a cross structure.

[0033] In this embodiment: when the steel wire rope is wound onto one side of the baffle 31, the steel wire rope will squeeze the surface of the partition 36 to drive the partition 36 to flip, so that one side of the partition 36 squeezes and limits the steel wire rope, and when winding another layer, one side of the partition 36 will separate the two layers of steel wire ropes to prevent the steel wire rope from sliding into the inside between the inner steel wire rope and the baffle 31, causing the steel wire rope to be entangled and tangled, and the diameter of the steel wire rope is the same as the parallel retaining edge gap on the adjacent partition 36, so that the partition 36 can separate the steel wire rope of each layer.

[0034] Going further:

[0035] like Figure 1-Figure 5 As shown:

[0036] In order to facilitate the fixing of the wire rope to the surface of the drum body 5, in an optional embodiment: the baffle 31 includes two groups of semicircular blocks, and the two groups of blocks are spliced ​​by bolts; the fixing block 32 is installed on the surface of the drum body 5 by bolts; the interior of the fixing block 32 is symmetrically threaded with a screw rod 33, the bottom end of the screw rod 33 is rotatably connected to a pressure block 35, the side of the pressure block 35 is fixedly connected to a slider 34, and the slider 34 is slidably connected to the surface of the baffle 31.

[0037] In this embodiment, the end of the steel wire rope is fixedly placed between the pressing block 35 and the drum body 5, and then the screw rod 33 is rotated to drive the pressing block 35 to squeeze and limit the steel wire rope, thereby completing the installation of the steel wire rope.

[0038] More specifically:

[0039] like Figure 1-Figure 5 As shown:

[0040] In combination with the above content, a guide assembly 4 is provided on the bottom surface of the fixed seat 1, and the guide assembly 4 includes two groups of reciprocating screws 43 symmetrically rotatably connected inside the fixed seat 1, and the two groups of reciprocating screws 43 are connected, and a moving block 44 is screwed on the surface of the reciprocating screw 43, and a roller 46 is symmetrically rotatably connected inside the moving block 44, and a sliding rod 45 is fixedly connected inside the fixed seat 1, and the moving block 44 is slidably connected to the surface of the sliding rod 45; a fixed sleeve on one side of the surface of the reciprocating screw 43 is provided with a synchronous belt 2 42, and a fixed sleeve on the surface of the reel body 5 is provided with a synchronous belt 1 41, and the synchronous belt 1 41 and the synchronous belt 2 42 are connected through a synchronous belt.

[0041] In the present embodiment: when the motor 2 pays out or reels in the steel wire rope, the steel wire rope passes between the two sets of rollers 46, and when the drum body 5 rotates, it can drive the synchronous belt 1 41 on one side to rotate, and drive the reciprocating screw rod 43 to rotate through the synchronous belt and synchronous belt 2 42, thereby driving the moving block 44 to move back and forth laterally, and guiding the steel wire rope through the roller 46 to facilitate the steel wire rope to be evenly wound around the surface of the drum body 5, thereby reducing the phenomenon of steel wire rope climbing.

[0042] Working principle: When the device is in use, the baffle 31 is conveniently installed on the surface of the drum body 5 through the fixing block 32, and then the end of the wire rope is fixedly placed between the pressure block 35 and the drum body 5, and the screw rod 33 is rotated to drive the pressure block 35 to squeeze and limit the wire rope to complete the installation of the wire rope. When the motor 2 releases or reels the wire rope, the wire rope passes between the two sets of rollers 46. When the drum body 5 rotates, it can drive the synchronous belt 1 41 on one side to rotate, and drive the reciprocating screw rod 43 to rotate through the synchronous belt and the synchronous belt 2 42, and then drive the moving block 44 to move back and forth horizontally, and the wire rope is squeezed through the rollers 46. The wire rope is guided to facilitate the uniform winding of the wire rope on the surface of the drum body 5, thereby reducing the wire rope climbing phenomenon. When the wire rope is wound onto one side of the baffle 31, the wire rope will squeeze the surface of the partition 36 to drive the partition 36 to flip, so that one side of the partition 36 squeezes and limits the wire rope, and when winding another layer, one side of the partition 36 will separate the two layers of wire rope to prevent the wire rope from sliding into the inside through the inner wire rope and the baffle 31, causing the wire rope to be entangled and tangled, and the diameter of the wire rope is the same as the parallel retaining edge gap on the adjacent partition 36, so that the partition 36 can separate the wire rope of each layer.

[0043] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention to solve the problems raised in the above background technology.
