[0008] Furthermore, the opening of the hook faces the connecting piece.
[0009] Furthermore, the hook is a U-shaped structure.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0032] The embodiments of the present application are further described in detail below with reference to the accompanying drawings:
[0033] First, please refer to Figure 1-Figure 3 , Figure 1 A schematic diagram of the structure of an anti-detachment connection device provided in this application; Figure 2 A schematic structural diagram of an anti-detachment connection device provided by the present application from another perspective; Figure 3 A structural schematic diagram of another perspective of an anti-slip connection device provided by the present application. The present application provides an anti-slip connection device, which includes a connector 100 and two hooks 300 arranged at intervals, the connector 100 is used to connect a first member to be connected 200 (for example, a centipede ladder body 700), the two hooks 300 are connected to the connector 100, and form two connection parts 400, and the openings of the two hooks 300 are respectively located on both sides of the connection line of the two connection parts 400.
[0034] In the above implementation process, the two hooks 300 on the anti-detachment connection device are suitable for connecting the second to-be-connected member 600. In the process of hanging the anti-detachment connection device on the second to-be-connected member 600, the anti-detachment connection device can be firstly brought close to the second to-be-connected member 600, and the second to-be-connected member 600 can be dropped between the two hooks 300, and then the anti-detachment connection device can be rotated in one direction to bring the openings of the two hooks 300 close to the second to-be-connected member 600, until the openings of the two hooks 300 are located above the second to-be-connected member 600, and then the anti-detachment connection device is moved downward, and finally the hooks 300 are hung on the second to-be-connected member 600.
[0035] Therefore, compared with only one hook 300 hung on the second member to be connected 600, two hooks 300 are hung on the second member to be connected 600, which can reduce the rotation of the anti-detachment connection device relative to the second member to be connected 600, thereby increasing the stability of the connection between the anti-detachment connection device and the second member to be connected 600. In addition, compared with the two hooks 300 being arranged in the same direction, the two hooks 300 are arranged in opposite directions so that the directions in which the second member to be connected 600 is separated from the two hooks 300 are different or opposite. When the anti-detachment connection device swings or shakes, when the second member to be connected 600 is about to be separated from one of the hooks 300, the other hook 300 will apply a force to the second member to be connected 600 to prevent it from being separated, thereby achieving effective anti-detachment.
[0036] In addition, the connecting line of the connecting portion 400 formed by connecting the two hooks 300 and the connecting member 100 should be understood as the connecting line of any points on the two connecting portions 400 .
[0037] The shapes of the connecting member can be various. For example, the connecting member can be a rod, a disc, or a U-shaped frame.
[0038] In a possible implementation, the connecting member 100 is a rod, and the two hooks 300 are respectively connected to the two ends of the connecting member 100. In this case, the openings of the two hooks 300 are respectively arranged on both sides of the connecting member 100.
[0039] In a possible implementation, a connecting body 500 is provided on the connecting member 100 , and the connecting body 500 is used to connect with the first member to be connected 200 , and the two hooks 300 are arranged in a centrally symmetrical manner relative to the center of the connecting body 500 .
[0040] In the above implementation process, the two hooks 300 are arranged in a centrally symmetrical manner relative to the center of the connecting body 500, and the first part to be connected 200 is connected to the connecting portion 400. Therefore, the first part to be connected 200 is located in the middle position of the two hooks 300, and the center of gravity is centered, which can improve the stability of the first part to be connected 200 and the anti-detachment connecting device connected to the second part to be connected 600.
[0041] In a possible implementation manner, an opening of the hook 300 faces the connecting member 100 .
[0042] In the above implementation process, the centipede ladder is connected to the connecting member 100, and the opening of the hook 300 is facing the centipede ladder, that is, the opening direction is downward, and the direction of the opening is opposite to the direction of the pulling force exerted on the hook 300 from the second part to be connected 600, which can improve the stability of the connection and effectively prevent the anti-detachment connection device from falling off from the second part to be connected 600 during use.
[0043] In a possible implementation manner, the hook 300 is a U-shaped structure.
[0044] In the above implementation process, the U-shaped hook 300 has a simple structure and its opening faces downward, so the connection is relatively stable.
[0045] In a possible implementation manner, an end of the hook 300 away from the connector 100 extends into the opening of the hook 300 to form a protrusion.
[0046] In the above implementation process, a protrusion is set at the end of the hook 300, but when the second connected member 600 moves along the inner wall of the hook 300 to the opening close to the hook 300, the protrusion can form a barrier to prevent the second connected member 600 from detaching from the hook 300.
[0047] In a possible implementation manner, at least one of the hooks 300 is provided with a wear-resistant elastic protective cover 310 .
[0048] When the anti-detachment connection device is hung on the second connecting member 600 to be connected (such as the railway contact network load-bearing cable) with higher structural stability requirements, the hook 300 may damage the structure of the load-bearing cable. Therefore, a wear-resistant elastic protective cover is provided on the hook 300 to play a buffering protection role between the hook 300 and the load-bearing cable, thereby protecting the load-bearing cable structure from damage.
[0049] Optionally, the wear-resistant elastic protective cover 310 may be made of rubber material or silicone material.
[0050] In a possible implementation manner, the connecting member 100 and the two hooks 300 are formed as one piece.
[0051] In the above implementation process, the connecting member 100 and the two hooks 300 are integrally formed, and the structural stability is relatively high.
[0052] In a possible implementation manner, at least one hook 300 is detachably connected to the connecting member 100 .
[0053] In some scenarios where two hooks 300 are not suitable, one of the hooks 300 can be disassembled for use, thereby expanding the use scenario of the anti-drop connection device. In addition, the hook 300 and the connector 100 are disassembled for easy storage and transportation.
[0054] In the second aspect, the present application also provides an anti-falling centipede ladder, please refer to Figure 4-Figure 7 , Figure 4 A schematic diagram of the structure of an anti-falling centipede ladder provided in this application; Figure 5 A schematic structural diagram of an anti-falling centipede ladder provided by the present application from another perspective; Figure 6 A schematic diagram of the structure of an anti-falling centipede ladder provided in the present application hung on a second member to be connected (rope); Figure 7 A schematic structural diagram of another perspective of an anti-slip centipede ladder provided by the present application, which is hung on a second member to be connected (rope). The anti-slip centipede ladder comprises a centipede ladder body 700 and an anti-slip connection device as described in any embodiment of the first aspect, and the centipede ladder body 700 is connected to a connection member 100 of the anti-slip connection device.
[0055] In the above implementation process, compared with the anti-slipping centipede ladder that uses one hook 300 to achieve the hanging connection, the above-mentioned anti-slipping connecting device is used to hang the centipede ladder body 700 on the rope through two oppositely arranged hooks 300. On the one hand, it can reduce the rotation of the centipede ladder body 700 relative to the rope, thereby increasing the stability of the centipede ladder and reducing the difficulty of climbing; on the other hand, the two hooks 300 are arranged in opposite directions so that the directions in which the rope detaches from the two hooks 300 are different or opposite. When the anti-slipping connecting device swings or shakes, when the rope wants to detach from one of the hooks 300, the other hook 300 will apply a force to the rope to prevent it from detaching, thereby achieving effective anti-slipping.
[0056] In a possible embodiment, the centipede ladder body 700 includes a load-bearing rod 800 and a plurality of pedals 900 arranged on both sides of the load-bearing rod 800. The load-bearing rod 800 is connected to the connector 100 of the anti-detachment connection device, and the two hooks 300 are arranged symmetrically with respect to the axis of the load-bearing rod 800.
[0057] In the above implementation process, the two hooks 300 are arranged symmetrically with the axis of the load-bearing rod 800, and the pedals 900 are distributed on both sides of the load-bearing rod 800. Therefore, the center of the centipede ladder is located at the center position between the two hooks 300, which can reduce the left and right swinging of the centipede ladder by the operator during climbing the centipede ladder, thereby providing stability and safety of the centipede ladder.
[0058] In a possible implementation, the arrangement direction of the two hooks 300 is parallel to an extension plane formed by the load-bearing rod 800 and the plurality of pedals 900 .
[0059] In the above implementation process, the two hooks 300 are arranged symmetrically with respect to the axis of the load-bearing rod 800, and the arrangement direction of the two hooks 300 is parallel to the extension surface formed by the load-bearing rod 800 and the multiple pedals 900. Therefore, each hook 300 is symmetrical about the extension surface formed by the load-bearing rod 800 and the multiple pedals 900, which can further improve the stability and safety of the centipede ladder.
[0060] It should be understood that the arrangement direction of the two hooks 300 refers to the direction in which one hook 300 points to the other hook 300. The extension plane formed by the load-bearing rod 800 and the plurality of pedals 900 refers to the plane where the axis of the load-bearing rod 800 and the length extension direction of the plurality of pedals 900 are located.
[0061] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application.
