Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] See also Figure 1-2 As shown, according to an embodiment of the present application, a cable drag chain protective tool is provided, the protective tool is arranged on one side of the lifting equipment, and the protective tool comprises: a bearing member 1, a fixing member 2 and a connecting chain 3;

[0026] The carrier 1 is provided with a fixed through groove, which forms a passage for the hinge to move. At least two groups of fixed components are arranged on the length direction of the carrier 1, and each group of the fixed components includes two fixed components 2. The two fixed components 2 are symmetrically arranged along the width direction of the carrier 1. The connecting chain 3 is arranged between each group of the fixed components and the lifting equipment, so that the carrier 1 supports the hinge.

[0027] Specifically, by installing the connecting chain 3 between the fixing member 2 and the lifting equipment, the bearing member 1 can be fixed at a certain height of the lifting equipment. The bearing member 1 can support and lift the cable chain to a certain height. The lifting height is preferably on the same horizontal plane as the upper part of the bent part of the cable chain during use. In this way, in some special application scenarios, when the cable chain is subjected to a large downward impact force, the downward impact force generated is generally the downward airflow generated during rocket launch or other working conditions that can generate a downward impact force on the cable chain. The support of the cable chain by the bearing member 1 can slow down the displacement of the upper part of the bent part of the cable chain when it is subjected to a downward impact force, reduce the probability of the cable chain breaking due to a large bend, improve the safety of the cable chain, protect the cable chain, and improve the efficiency of the lifting equipment.

[0028] Among them, there are multiple groups of fixed components, which are arranged at intervals along the length direction of the carrier 1. Each connecting chain 3 is adapted to be connected with a fixed component to achieve fixed connection of the carrier 1 at multiple positions, thereby improving the stability of the carrier 1 in supporting the cable drag chain during use.

[0029] The connecting chain 3 is installed between the lifting device and the fixing member 2, so as to facilitate the adjustment of the position of the bearing member 1 by adjusting the length of the connecting chain 3, and further realize the adjustment of the supporting height of the cable drag chain.

[0030] The connecting chain 3 is one of a chain, a cable and a wire rope.

[0031] The bearing member 1 comprises: a bottom plate 11 and a vertical plate 12;

[0032] The vertical plates 12 are disposed on both sides of the bottom plate 11 , and the vertical plates 12 and the bottom plate 11 form the fixed through groove.

[0033] Specifically, the bearing member 1 includes a bottom plate 11 and a vertical plate 12. The vertical plate 12 is vertically welded to both sides of the bottom plate 11. The top is an open structure. The bottom plate 11 and the vertical plate 12 form a fixed through groove for placing a cable drag chain. The cable drag chain can be placed in the fixed through groove from the top. The bottom plate 11 can support the cable drag chain, and the vertical plate 12 can limit and protect the cable drag chain from both sides, thereby reducing the probability of the cable drag chain detaching from the bearing member 1 during use.

[0034] The carrier 1 further comprises: a roller 13;

[0035] The rollers 13 are disposed between the vertical plates 12 , and the rollers 13 are located in front of and behind the bottom plate 11 .

[0036] Specifically, there are two rollers 13, which are installed between the vertical plates 12 on the front and rear sides of the bottom plate 11 through an axis, and the rollers 13 can rotate along the axis. When the cable drag chain enters or slides out of the fixed through groove, the original sliding contact mode between the cable drag chain and the bottom plate 11 is changed to the rolling contact mode between the cable drag chain and the rollers 13 in the present application, which reduces the relative friction between them. When the cable drag chain is subjected to a downward impact force, it can also improve the efficiency of the cable drag chain entering and exiting the fixed through groove, realize the buffering of the force on the cable drag chain, avoid the cable drag chain from getting stuck with the bottom plate 11 during use, and improve the safety of use.

[0037] The top of the outer circumferential surface of the roller 13 is not lower than the upper wall surface of the bottom plate 11 .

[0038] The top of the outer circumferential surface of the roller 13 is parallel to the upper wall surface of the bottom plate 11 .

[0039] Specifically, the top of the outer circumferential surface of the roller 13 is parallel to or higher than the upper wall surface of the bottom plate 11. Preferably, the top of the outer circumferential surface of the roller 13 is parallel to the upper wall surface of the bottom plate 11, that is, there is no height difference between the top of the roller 13 and the upper wall surface of the bottom plate 11, so that the cable drag chain can smoothly pass through the roller 13 and enter the bottom plate 11, reducing the probability of the cable drag chain getting stuck when entering the fixed through groove, and the cable drag chain moves more smoothly from the fixed through groove.

[0040] The fixing member 2 is arranged on the vertical plate 12 , a fixing passage is opened in the middle of the fixing member 2 , the connecting chain 3 is connected to the lifting equipment through the fixing passages of the two fixing members 2 , and the middle of the connecting chain 3 is located below the bottom plate 11 .

[0041] Specifically, each fixing assembly includes two fixing parts 2, which are respectively connected to two vertical plates 12 in the width direction of the carrier 1. Both ends of a connecting chain 3 pass through the fixing passages of the fixing parts 2, and the middle part is located at the bottom of the bottom plate 11 along the width direction of the carrier 1, so that the connecting chain 3 has a stronger supporting and fixing ability for the carrier 1 and a more stable support for the cable drag chain.

[0042] The fixing member 2 is welded to the vertical plate 12 .

[0043] Specifically, the fixing member 2 is connected to the vertical plate 12 by welding, so that the connection between the fixing member 2 and the vertical plate 12 is more stable.

[0044] A buffer layer is disposed on a side of the vertical plate 12 away from the fixing member 2 .

[0045] Specifically, the buffer layer is arranged on the side of the vertical plate 12 away from the fixing member 2. The buffer layer is made of rubber and can protect both sides of the cable drag chain in the fixing groove, thereby reducing the probability of damage caused by collision.

[0046] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
