Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable protection, specifically to a protective device for crane cables. Background Technology
[0002] Crane cables are primarily used for power supply and control signal transmission, and are a critical component for the normal operation of cranes. During crane operation, cables may be subjected to mechanical impacts, compression, abrasion, etc., which can cause damage. Cranes typically operate outdoors or in harsh environments, and without protective measures, they are easily damaged by external forces. In rainy or snowy weather, cables may be submerged in water for extended periods, which can eventually lead to cable breakage and accidents such as electric shock and sudden equipment shutdown, adversely affecting the safety management of production units.
[0003] While current crane cable protection devices can protect long cables through splicing, their splicing structure is relatively simple. Under external impact or compression, the splices are prone to breakage or loosening, failing to provide continuous and effective protection and posing safety hazards. Therefore, there is an urgent need to design a crane cable protection device.
[0004] For example, prior art document 1 with application number 202121612336.5 discloses a cable protection device for a gantry crane, which is composed of several protective grooves spliced together; the protective groove includes a groove body, a partition plate is provided in the middle of the groove body, and a cover plate is provided on both sides of the groove body.
[0005] For example, prior art document 2 with application number 202222819808.5 discloses a cable protection device for crossing roads, including a body and a guide block; the body has a cavity inside, and the front and rear ends of the body are open and connected. A fixing plate and a limiting rod are provided in the cavity. The upper surface of the fixing plate is provided with a sliding groove. The bottom ends of the two limiting rods are slidably disposed in the sliding groove. The two limiting rods together constitute a clamping structure for clamping the cable.
[0006] Although the above two types of cable protection devices can protect long cables by splicing, their splicing structure is relatively simple. When subjected to external impact or compression, the splice is prone to breakage or loosening, thus failing to provide continuous and effective protection for the cable and posing a safety hazard.
[0007] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0012] Furthermore, in order to facilitate a simple and stable splicing of the protective base plates according to the required length of the crane cable, and to prevent breakage or loosening at the connection point of the protective base plates under external impact or compression, thus providing continuous and effective protection for the crane cable, a drainage hole is provided at the bottom of the connecting groove, and a through hole is provided at the top of the connecting groove; two adjacent connecting components are arranged symmetrically, and two protective base plates are spliced together by two connecting components; the connecting components include: a connecting handle, located inside the connecting groove; a pull pin, located at the top center of the connecting handle and cooperating with the through hole; a limiting plate, located on one side of the pull pin and cooperating with the connecting handle; a shaft pin, located on one side of the top of the connecting handle; and a hook, located on one side of the connecting handle and cooperating with the shaft pin and the limiting plate; the hook is C-shaped, and one end of the hook has a groove that cooperates with the limiting plate.

[0026] According to an embodiment of the present invention, a protective device for crane cables is provided.
[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-5 As shown, the crane cable protection device according to an embodiment of the present invention includes: a protection body 1, which is composed of several protective base plates 2 connected sequentially from left to right on the crane; a protective cover 3, which is disposed at the top of the protective base plate 2; several rubber blocks 4, which are disposed at the bottom of the protective base plate 2 for protecting the internal cable; several drainage holes 5, which are opened at the bottom of the protective base plate 2 for timely drainage of accumulated water and dissipation of heat generated during cable use into the air; connecting grooves 6, which are symmetrically opened at both ends of both sides of the protective base plate 2; and connecting components 7, which are disposed inside the connecting grooves 6.
[0028] By utilizing the aforementioned technical solution, this utility model, through the combined action of the protective base plate 2, protective cover 3, connecting groove 6, and connecting component 7, enables a simple and stable splicing of the protective base plates 2 according to the required length of the crane cable. This ensures that the crane cable can be placed tightly against the receiving groove 8, providing continuous and effective protection for the crane cable and improving its service life and safety. The combined action of the protective base plate 2 and protective cover 3 allows the crane cable to be easily placed within the receiving groove 8, ensuring a tight fit and reducing cable wear, thus improving its service life and safety. Furthermore, the combined action of the protective base plate 2, connecting groove 6, and connecting component 7 enables a simple and stable splicing of the protective base plates 2 according to the required length of the crane cable. Under external impact or compression, the connection points of the protective base plates 2 will not break or loosen, providing continuous and effective protection for the crane cable.
[0029] It should be explained that a crane is a device used to lift, move, and lower heavy objects; a crane cable is a cable used to provide power and signal transmission to a crane; a crane cable protection device is a device used to protect cables from physical damage, environmental influences, and excessive wear; wherein, the crane cable protection device is installed on the outside of the crane cable, and the crane cable is installed on the crane.
[0030] Furthermore, the crane cable protection device of this utility model can not only protect crane cables, but also adapt to other types of cables by changing the parameters of the protective base plate 2 and the protective cover 3, and provide protection according to the characteristics of other types of cables, thereby effectively protecting other types of cables.
[0031] In one embodiment, for the protective base plate 2 and the protective cover 3, a plurality of receiving grooves 8 are formed between the protective base plate 2 and the protective cover 3, and the top of the receiving groove 8 is an arc-shaped structure; the top of the protective base plate 2 is provided with a plurality of trapezoidal grooves 9 that cooperate with the protective cover 3; the bottom of the protective cover 3 is provided with a plurality of trapezoidal blocks 10 that cooperate with the trapezoidal grooves 9, so that the crane cable can be conveniently placed in the receiving groove 8. The receiving groove 8 ensures that the crane cable can be placed tightly, reducing cable wear and improving the service life and safety of the cable.
[0032] The working principle of the protective base plate 2 and the protective cover 3 is as follows: In the initial state, the operator places the crane cable on the protective base plate 2, aligns the trapezoidal block 10 at the bottom of the protective cover 3 with the trapezoidal groove 9 at the top of the protective base plate 2, and slides the protective cover 3 until it is aligned with one side of the protective base plate 2. Several receiving grooves 8 are formed between the protective base plate 2 and the protective cover 3, and the crane cable is then attached to the inner wall of the receiving groove 8 for protection. When it is necessary to disassemble, slide the protective cover 3 in the opposite direction until the trapezoidal block 10 is away from the trapezoidal groove 9, and the protective cover 3 can be separated from the protective base plate 2.
[0033] In one embodiment, for the connecting component 7, a drainage hole 11 is provided at the bottom end of the connecting groove 6, and a through hole 12 is provided at the top end of the connecting groove 6; two adjacent connecting components 7 are arranged symmetrically, and two protective base plates 2 are spliced together by the cooperation of two connecting components 7; the connecting component 7 includes: a connecting handle 701, disposed inside the connecting groove 6; a pull pin 702, disposed at the top center of the connecting handle 701 and cooperating with the through hole 12; a limiting plate 703, disposed on one side of the pull pin 702 and cooperating with the connecting handle 701; and a shaft pin. 704 is located on one side of the top of the connecting handle 701; hook 705 is located on one side of the connecting handle 701 and cooperates with the shaft pin 704 and the limiting plate 703; hook 705 is C-shaped, and one end of hook 705 has a groove 7051 that cooperates with the limiting plate 703, so that the protective base plates 2 can be easily and firmly spliced according to the required length of the crane cable. When subjected to external impact or compression, the connection of the protective base plates 2 will not break or loosen, providing continuous and effective protection for the crane cable.
[0034] The working principle of the connecting components 7 is as follows: When the protective base plate 2 needs to be connected, the operator brings the two connecting components 7 close to each other. Under the action of the shaft pin 704, one hook 705 will rotate under the push of the other hook 705 and enter the connecting handle 701 of the other. After the hook 705 rotates to a certain angle, the limiting plate 703 on one side of the pull pin 702 will enter the groove 7051, forming a limit on the two hooks 705, thereby realizing a firm connection between the protective base plates 2. When the protective base plate 2 needs to be disassembled, the operator pulls up the pull pin 702, and the limiting plate 703 will move away from the groove 7051, releasing the limit on the two hooks 705. The operator applies opposing forces to the protective base plates 2 on both sides, thereby realizing the disassembly of the protective base plates 2.
[0035] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0036] In practical applications, the operator selects an appropriate amount of protective base plate 2 and protective cover 3 according to the required length of the crane cable. The crane cable is placed on the protective base plate 2, and the trapezoidal block 10 at the bottom of the protective cover 3 is aligned with the trapezoidal groove 9 at the top of the protective base plate 2. The protective cover 3 is slid until it aligns with one side of the protective base plate 2, forming several receiving grooves 8 between the protective base plate 2 and the protective cover 3. The crane cable is then placed against the inner wall of the receiving grooves 8 (the specific working principle of the protective base plate 2 and protective cover 3 is as described above). Subsequently, the operator aligns the connecting grooves 6 of the protective base plate 2 and brings the two connecting components 7 close together. Under the action of the shaft pin 704, one hook 705 rotates under the push of the other hook 705 and enters the connecting handle 701 of the other. After the hook 705 rotates to a certain angle, it pulls... The limiting plate 703 on one side of pin 702 will enter the groove 7051, limiting the two hooks 705, thereby achieving a firm connection between the protective base plates 2 (the specific working principle of the connecting component 7 is as described above), and achieving effective protection for the cable; when a problem occurs in a section of the protective base plate 2, the operator pulls up pin 702, the limiting plate 703 will move away from the groove 7051, releasing the limitation on the two hooks 705, and the operator applies opposing forces to the protective base plates 2 on both sides to achieve disassembly between the protective base plates 2 (the specific working principle of the connecting component 7 is as described above). Then the operator slides the protective cover 3 on the corresponding protective base plate 2 in the opposite direction until the trapezoidal block 10 moves away from the trapezoidal groove 9, thereby achieving separation of the protective cover 3 from the protective base plate 2 (the specific working principles of the protective base plate 2 and the protective cover 3 are as described above).
[0037] In summary, with the assistance of the above-mentioned technical solution of this utility model, the protective base plate 2, protective cover 3, connecting groove 6, and connecting component 7 work together to easily and securely splice the protective base plates 2 according to the required length of the crane cable, ensuring that the crane cable can be placed tightly against the receiving groove 8, providing continuous and effective protection for the crane cable, and improving the service life and safety of the cable; the protective base plate 2 and protective cover 3 work together to facilitate the placement of the crane cable in the receiving groove 8, which ensures that the crane cable can be placed tightly against the receiving groove 8, reducing cable wear and improving the service life and safety of the cable; the protective base plate 2, connecting groove 6, and connecting component 7 work together to easily and securely splice the protective base plates 2 according to the required length of the crane cable, and the connection of the protective base plate 2 will not break or loosen when subjected to external impact or compression, providing continuous and effective protection for the crane cable.
