Description

Technical Field

[0001] This utility model relates to the field of cable hoisting technology, specifically a cable sling device. Background Technology

[0002] Cable bridges are needed to span production roads. These bridges, 13 meters high, are placed on either side of the road, which is 18 meters wide. The cables can be stretched to a height of 10 meters to allow for the normal passage of the largest production truck, the 830E. According to the production plan, coal mine electric shovels are frequently moved to different locations for operation. Therefore, the cable power supply method needs to be replanned and a reasonable power supply method developed. However, in the actual production site, to effectively improve power quality and shorten the power supply radius, it is necessary to rebuild the cable bridges for the cables crossing the production road, thus requiring the cables to be re-lifted.

[0003] In the existing technology, cable slings need to be clamped with two steel plates and then fixed with bolts. This requires at least three workers to complete the work properly, and it is inefficient and physically demanding. In addition, the bolts are prone to corrosion after long-term use, making disassembly difficult.

[0004] Therefore, a cable sling device was designed based on the above-mentioned technical problems. Utility Model Content

[0005] To address the problem that existing technologies cannot allow one person to secure cable slings, this utility model proposes a cable sling device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a cable sling device, including a cable sling body. The cable sling body includes a cable placement frame and a lifting frame. The cable placement frame has a groove with two connected ends. The groove is arc-shaped. The lifting frame is located on the side of the groove. The lifting frame includes a frame structure. The top of the frame structure has a lifting through hole. The cable sling body has a pressure plate assembly. The pressure plate assembly has a wire rope hole. The lifting wire rope passes through the lifting through hole and connects to the wire rope hole. The lifting through hole and the wire rope hole are used for hinged connection between the pressure plate assembly and the cable sling body. When lifting the cable, the pressure plate assembly rotates downward to compress the cable.

[0007] Preferably, the pressing plate assembly includes a mounting frame and a lower pressing plate. The lower pressing plate is located at the front end of the mounting frame and is an arc-shaped pressing plate with its center pointing downwards. When the cable is lifted, the arc-shaped pressing plate fits and presses against the cable. The wire rope hole is located in the upper part of the mounting frame.

[0008] Preferably, the hoisting frame is an isosceles trapezoidal frame, with a groove at the bottom edge of the hoisting frame, and a mounting plate below the hoisting frame at the groove. The groove is used to place the mounting frame, and the mounting plate is used to hinge the mounting frame.

[0009] Working principle: The cable is placed in the groove, forming an arc-shaped groove that matches the cable height. It is then hinged to the clamping assembly and the lifting frame, allowing the clamping assembly to rotate relative to the lifting frame. The lifting wire rope passes through the lifting through-hole and connects to the wire rope hole. When the lifting wire rope is dragged to lift the cable, the cable's own weight causes the clamping assembly to rotate. Utilizing the principle of reaction force, the cable's own weight clamps the cable; the heavier the cable, the greater the force, thus compressing the cable and preventing it from falling during lifting.

[0010] Preferably, the cable placement frame is a semi-circular arc with the center facing downwards. Since outdoor cables are prone to frost and hardening of rubber in low-temperature environments, if the placement frame is directly straight, it may cause problems such as hard breakage at the hanging position. Therefore, the arc design ensures that the cable does not have a right angle problem when hanging, and further forms a support, which further facilitates the installation of the cable on this application.

[0011] Preferably, the cable tray and the hoisting frame are integrally formed, which ensures the hoisting strength of this application and avoids problems such as weld breakage due to welding or other issues.

[0012] Preferably, the cable sling body and the pressure plate assembly are both made of aluminum alloy, which reduces the weight of this application while ensuring strength.

[0013] The advantages of this utility model are:

[0014] This utility model avoids the problem of fixing the cable when slinging the cable by designing the cable sling body and pressure plate assembly, reducing the workload of operators and allowing a single operator to carry out the operation, which greatly improves work efficiency.

[0015] 2. The cable rack described in this utility model is a semi-circular arc with the center facing downwards. Since outdoor cables are prone to frost and hardening of rubber in low-temperature environments, if the rack is straight, it may cause problems such as hard breakage at the hanging position. Therefore, the arc design ensures that the cable does not have a right angle problem when hanging, and further forms a support, which makes it more convenient to install the cable on this application.

[0016] 3. The cable rack and hoisting frame described in this utility model are integrally formed, which ensures the hoisting strength of this application and avoids problems such as breakage at the weld points due to welding or other issues. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5As shown, a cable sling device includes a cable sling body 1, which includes a cable placement frame 2 and a lifting frame 3. The cable placement frame 2 has a groove 201 with both ends connected. The groove 201 is arc-shaped. The lifting frame 3 is located on the side of the groove 201 and includes a frame structure. The top of the frame structure has a lifting through hole 4. The cable sling body 1 is provided with a pressure plate assembly 5. The pressure plate assembly 5 has a wire rope hole 501. The lifting wire rope 6 passes through the lifting through hole 4 and connects to the wire rope hole 501. The lifting through hole 4 and the wire rope hole 501 are used for hinged connection between the pressure plate assembly 5 and the cable sling body 1. When lifting the cable, the pressure plate assembly 5 is used to rotate downward to press the cable tightly.

[0026] Preferably, the pressing plate assembly 5 includes a mounting frame 502 and a lower pressing plate 503. The lower pressing plate 503 is located at the front end of the mounting frame 502. The lower pressing plate 503 is an arc-shaped pressing plate with the center facing downward. When the cable is lifted, the arc-shaped pressing plate fits and presses against the cable. The wire rope hole 501 is located in the upper part of the mounting frame 502.

[0027] Preferably, the hoisting frame 3 is an isosceles trapezoidal frame, and a groove 201 is provided at the lower side of the hoisting frame 3. A mounting plate 301 is provided below the hoisting frame 3 at the groove 201. The groove 201 is used to place the mounting frame 502, and the mounting plate 301 is used to hinge the mounting frame 502.

[0028] Working principle: The cable is placed in the groove 201, forming an arc-shaped groove 201 that matches the height of the cable. Then, it is hinged to the clamping assembly 5 and the lifting frame 3, allowing the clamping assembly 5 to rotate relative to the lifting frame 3. The lifting wire rope 6 passes through the lifting through hole 4 and connects to the wire rope hole 501. When the wire rope is dragged to lift the cable, the weight of the cable itself drives the clamping assembly 5 to rotate. Utilizing the principle of reaction force, the cable is clamped by its own weight. The heavier the cable, the greater the force, thus compressing the cable and preventing it from falling during the lifting process.

[0029] Preferably, the cable placement frame 2 is a semi-circular arc with the center facing downwards. Since outdoor cables are prone to frost and hardening of rubber in low-temperature environments, if the placement frame is directly straight, it may cause problems such as hard breakage at the hanging position. Therefore, the arc design ensures that the cable does not have a right angle problem when hanging, and further forms a support, which further facilitates the installation of the cable on this application.

[0030] Preferably, the cable tray 2 and the hoisting frame 3 are integrally formed, which ensures the hoisting strength of this application and avoids problems such as breakage at the weld points due to welding or other issues.

[0031] The specific implementation site is the Shengli Open-pit Coal Mine, which is located in a cold area. During the implementation process, on-site trials showed that it only takes 10 seconds to install the cable onto the device. The highest ambient temperature in summer can reach +40℃, and the lowest ambient temperature in winter can reach -40℃.

[0032] Considering that rigid materials are more fragile and prone to cracking in the cold winter weather in the specific embodiment, the cable sling device needs to be made with higher strength and thicker material. However, with thicker material, the new cable sling device is much heavier, four times the weight of the existing cable sling device, which increases the labor intensity of personnel and is not easy to use in winter. Therefore, in order to reduce the weight of the device while ensuring strength, the cable sling body 1 and the pressure plate assembly 5 are both made of aluminum alloy.
