Description

Technical Field

[0001] The utility model relates to an improved structure of a steel wire rope for opening and closing an arc gate. Background Art

[0002] At present, in water conservancy projects, a machine room for installing a wire rope electric hoist is set above the radial gate. The wire rope electric hoist is installed under the floor of the machine room. The upper end of the wire rope for opening and closing the radial gate is hung with the lower end of the wire rope electric hoist, and the lower end is connected to the lower part of the radial gate. The wire rope electric hoist pulls up or lowers the radial gate through the wire rope for opening and closing the radial gate to realize the opening and closing of the radial gate. The moving trajectory of the radial gate is an arc.

[0003] The two existing steel wire ropes for opening and closing radial gates have the following defects:

[0004] 1. The structure of the first type of steel wire rope for opening and closing the radial gate is as follows: Figure 1 As shown, the steel wire rope includes a rope body, a cast iron connector ( Figure 1 Only the cast iron connector at the lower end of the rope body is shown in the figure. The structure of the steel wire rope is relatively bulky. The rope body and the cast iron connector are anchored by liquid metal infusion. The process is complicated, the operation is difficult, and the connection quality after cooling and solidification is difficult to control. In addition, the high temperature of the liquid metal during the processing process can easily destroy the protective oil layer on the surface of the rope body. The rope body is often rusted and broken in the area within about 5 cm outside the anchoring contact surface, resulting in a low tensile strength of the steel wire rope. In addition, when the steel wire rope is used, the cast iron connector at the lower end of the rope body is often buried underwater, easy to rust, and aquatic organisms grow on its surface. After the cast iron connector is rusted, it is very difficult to adjust its length.

[0005] 2. The structure of the second type of wire rope for opening and closing the radial gate is as follows: Figure 2 As shown, the steel wire rope includes a rope body and a rope loop provided at either end of the rope body by a braiding and inserting processing method. Although it solves the corrosion and wire breakage problems of the first steel wire rope for opening and closing the radial gate to a certain extent, it still has the defects of being very difficult to manually adjust its length, and being difficult to inspect and maintain. The length of the steel wire rope is difficult to fine-tune, and the length adjustment accuracy of the steel wire rope is difficult to control;

[0006] 3. Regardless of which of the above-mentioned steel wire ropes for opening and closing the radial gate is installed, when checking, adjusting, and resetting the lower end of the steel wire rope for opening and closing the radial gate and the lower connection point of the radial gate (commonly known as the underwater hanging point) during use, it is necessary to first close the water-facing side of the corresponding gate hole through another inspection gate, and then lift the radial gate to an appropriate height. The construction workers need to wade in water (the water level is close to waist-high) for inspection and maintenance, which is time-consuming, difficult, inconvenient, and also dangerous.

[0007] In summary, the above-mentioned two types of steel wire ropes for opening and closing radial gates have unreasonable structural designs and cannot meet the needs of operation and maintenance of radial gates. Utility Model Content

[0008] In view of the deficiencies in the prior art, the utility model provides an improved structure of a steel wire rope for opening and closing a radial gate, the length of which can be precisely fine-tuned and can meet the needs of operation and maintenance of the radial gate.

[0009] The utility model provides an improved structure of a steel wire rope for opening and closing a radial gate, which comprises an upper connector and a lower connector, and the upper connector and the lower connector are made of stainless steel;

[0010] The upper connector adopts an internally hollow double-threaded sleeve structure. The middle section of the upper connector is provided with a threaded through hole perpendicular to its axis. The threads on both sides of the upper connector are spaced apart from each other and have opposite spiral directions. The two sides of the upper connector are respectively threadedly connected with the first adjusting screw and the second adjusting screw. The end of the first adjusting screw away from the upper connector is fixedly connected with the upper lifting ring, and the end of the second adjusting screw away from the upper connector is fixedly connected with the transfer rod. The end of the transfer rod away from the upper connector is fixedly connected with one end of the wire rope, and the wire rope is made of stainless steel.

[0011] One end of the lower connector is fixedly connected with a lower lifting ring, and the other end of the lower connector is fixedly connected with the other end of the steel wire rope.

[0012] Furthermore, the steel wire rope is fixedly connected to the transfer rod and the lower connector respectively by cold-pressing sleeve connection.

[0013] Furthermore, a first locking nut is threadedly connected to the first adjusting screw, and a second locking nut is threadedly connected to the second adjusting screw, and both ends of the upper connector are in close contact with the first locking nut and the second locking nut respectively.

[0014] For the purpose of explaining the problem concisely and clearly, the improved structure of the steel wire rope for opening and closing the arc gate described in the utility model is referred to as this structure below.

[0015] When this structure is installed, the upper lifting ring of the first adjusting screw is hung with the lower end of the wire rope electric hoist, and the lower lifting ring of the lower connector is connected with the lower part of the radial gate. The wire rope electric hoist pulls up or lowers the radial gate through this structure to realize the opening and closing of the radial gate.

[0016] Compared with the prior art, this structure has the following beneficial effects:

[0017] The upper connector, the first adjusting screw and the second adjusting screw in the present structure form a split adjusting structure. During use, if it is necessary to check, adjust or reset the underwater lifting point of the radial gate (i.e., the connection between the lower lifting ring of the present structure and the lower part of the radial gate), the upper connector can be rotated manually. Since the present structure is fixedly arranged between the wire rope electric hoist and the radial gate, the rotation of the upper connector will force the first adjusting screw and the second adjusting screw to extend outward or retract inward synchronously relative to the upper connector. The overall connection length of the split adjusting structure is precisely fine-tuned, so that the length of the present structure can be precisely fine-tuned. The present structure can meet the needs of radial gate operation and maintenance operations. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0031] like Figure 3-Figure 7 As shown:

[0032] The structure includes an upper connector 1 and a lower connector 2. The upper connector 1 and the lower connector 2 are made of 304 stainless steel. Both are made of stainless steel blanks by lathe processing. They not only have good integrity, but also overcome the defects of cast iron connectors in the background technology that are easy to rust and not corrosion-resistant.

[0033] The upper connector 1 adopts an internal hollow double-threaded sleeve structure. A threaded through hole 3 perpendicular to its axis is opened in the middle section of the upper connector 1. The upper thread and the lower thread in the upper connector 1 are spaced apart from each other and have opposite spiral directions. The axis of the threaded through hole 3 is located between the upper thread and the lower thread in the upper connector 1.

[0034] The upper side of the upper connector 1 is threadedly connected to the first adjusting screw 4 , and the lower side of the upper connector 1 is threadedly connected to the second adjusting screw 5 .

[0035] An upper lifting ring 6 is fixedly connected to the upper end of the first adjusting screw rod 4 away from the upper connector 1, and the upper lifting ring 6 is rotatably connected to the lower end of the wire rope electric hoist 10 through an axle pin, so that the operation is simple, safe and reliable.

[0036] The lower end of the second adjusting screw 5 away from the upper connector 1 is fixedly connected to a transfer rod 7, and the lower end of the transfer rod 7 away from the upper connector 1 is fixedly connected to the upper end of a steel wire rope 8, and the steel wire rope 8 is made of stainless steel with high tensile strength.

[0037] The lower end of the lower connector 2 is fixedly connected with a lower lifting ring 9, the upper end of the lower connector 2 is fixedly connected to the lower end of the wire rope 8, the lower part of the arc gate 11 is fixedly connected with a lower lifting ear 14, and the lower lifting ring 9 is rotatably connected with the lower lifting ear 14 through an axle pin, so that the operation is simple, safe and reliable.

[0038] Through the hydraulic press, the steel wire rope 8 is fixedly connected to the transfer rod 7 and the lower connector 2 by cold-pressing sleeve connection, so that the steel wire rope 8 is tightly and firmly connected to the transfer rod 7 and the lower connector 2, overcoming the defect of the first type of steel wire rope for opening and closing the radial gate in the background technology that the high-temperature liquid metal is poured and anchored during processing, which has a negative impact on its tensile performance, which makes the tensile strength of the present structure higher.

[0039] A first locking nut 12 is threadedly connected to the first adjusting screw 4, and a second locking nut 13 is threadedly connected to the second adjusting screw 5. The upper end of the upper connector 1 is in close contact with the first locking nut 12, and the lower end of the upper connector 1 is in close contact with the second locking nut 13.

[0040] As described above, the upper connector 1, the first adjusting screw 4, and the second adjusting screw 5 in the present structure form a split adjusting structure. When the overall connection length of the split adjusting structure is adjusted and determined, the first locking nut 12 and the second locking nut 13 can lock the position of the upper connector 1 so that the length of the present structure can be stabilized.

[0041] like Figure 8 As shown, Figure 8 This is the tensile test curve of the steel wire rope in this structure. Figure 8 The horizontal axis is displacement (mm) and the vertical axis is force (KN). The specification of the steel wire rope in this structure is: Φ36*2M, and the maximum force of the tensile test is 532.50KN.

[0042] like Fig. 9 As shown, Fig. 9 This is the tensile test curve of the steel wire rope and the lower connector in this structure. Fig. 9 The horizontal axis is displacement (mm) and the vertical axis is force (KN). The specification of the steel wire rope in this structure is: Φ36*5.4M, and the maximum force of the tensile test is 580.36KN.

[0043] like Fig.10 As shown, Fig.10 This is the static tension test curve of the steel wire rope and the lower connector in this structure. Fig.10 The horizontal axis is displacement (mm) and the vertical axis is force (KN). The specification of the steel wire rope in this structure is: Φ36*5.4M. The maximum force of the static tensile test is 353.63KN. The test method is: static.

[0044] The use process of this structure is as follows: When using this structure, if it is necessary to check, adjust, or reset the underwater hanging point of the radial gate 11 (i.e., the connection between the lower hanging ring 9 of this structure and the lower hanging ear 14 of the radial gate 11), first, the first locking nut 12 and the upper connector 1, and the second locking nut 13 and the upper connector 1 are both separated from the close contact; then, an adjusting rod (the adjusting rod is not shown in the attached drawings) is used to horizontally penetrate the threaded through hole 3, and the upper connector 1 can be rotated by manually rotating the adjusting rod. Since this structure is fixedly arranged between the wire rope electric hoist 10 and the radial gate 11, the rotation of the upper connector 1 will force the first adjusting screw 4, The second adjusting screw 5 synchronously extends outward or retracts inward relative to the upper connector 1, and the overall connection length of the split adjusting structure (including the upper connector 1, the first adjusting screw 4, and the second adjusting screw 5) is precisely fine-tuned; when the overall connection length of the split adjusting structure is adjusted and determined, the first locking nut 12 and the upper connector 1, and the second locking nut 13 and the upper connector 1 are finally brought into close contact, that is, the first locking nut 12 and the second locking nut 13 lock the position of the upper connector 1, and the length of the present structure is stabilized; thereby, the length of the present structure can be precisely fine-tuned, and the present structure can meet the needs of radial gate operation and maintenance operations.
