Description

Technical Field

[0001] The utility model relates to the technical field of floating bridge connection, in particular to a connecting piece for a concrete floating bridge unit. Background Art

[0002] A concrete floating bridge is a bridge structure that floats on the water surface based on the principle of buoyancy. It is mainly composed of concrete components and buoyancy units. Unlike traditional fixed bridges, concrete floating bridges do not rely on ground support. Instead, they use buoyancy and anchoring measures to keep the bridge floating firmly on the water surface, capable of carrying a certain weight of vehicles, pedestrians, and other means of transportation. The structure of a concrete floating bridge includes multiple floating bridge units, each of which is made of concrete material and is usually rectangular or other shapes suitable for floating on the water surface. In actual applications, steel ropes are usually set at the connection of the floating bridge units and fixed to the concrete floating bridge units through connectors. By using steel ropes to connect, not only can a close connection between the floating bridge units be achieved, but also tensioning and tightening effects can be provided, ensuring the long-term stable operation of the floating bridge in the water environment.

[0003] In the application of concrete floating bridges, the action of waves on the water surface causes the floating bridge units to float up and down. However, due to the periodic changes in waves and water flow, the steel rope will be constantly stretched and compressed during the connection process, especially in the middle of the connection point, which often bears a large tensile force. Long-term traction and tensioning may cause fatigue fracture in the middle of the steel rope. In current technology, once the steel rope breaks, there is a lack of emergency locking mechanism, and the broken ends cannot be fixed in time after the steel rope breaks, thereby preventing the floating bridge from dispersing.

[0004] In order to solve the above problems, the present application proposes a connector for a concrete floating bridge unit. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0028] like Figure 1-6 As shown, the present invention proposes a connector for a concrete floating bridge unit, comprising a steel rope 1 and two floating bridge bodies 2, wherein the two floating bridge bodies 2 are connected by the steel rope 1;

[0029] In this embodiment, two sets 3 are fixedly sleeved on the middle part of the steel rope 1. The sets 3 include sleeves 31. The two sleeves 31 are fixedly sleeved on the middle part of the steel rope 1. The two sleeves 31 are installed with a sleeve disc 32 sleeved on the steel rope 1 at one end close to each other.

[0030] In this embodiment, elastic clips 4 are installed on both kits 3, and a first steel cable 5 is connected between the two elastic clips 4. The elastic clips 4 include a connecting rod 41, which slides horizontally through the sleeve 32. The connecting rods 41 on the two sleeves 32 are each installed with an end block 42 at one end away from each other. A first spring 43 located between the sleeve 32 and the end block 42 is sleeved on the connecting rod 41, and the two ends of the first spring 43 are respectively connected to the sleeve 32 and the end block 42. A slot is opened in the sleeve 32 and is located on one side of the end block 42. A slot 44 adapted to the slot is installed on the end block 42. The two ends of the first steel cable 5 are respectively connected to the connecting rods 41 on the two sleeves 32.

[0031] In this embodiment, a card slot is opened in the kit 3, and a pressure warning component 6 is installed in the card slot. The pressure warning component 6 includes a pressure sensor 61, a second spring 62, an alarm 63 and a controller 64. The second spring 62 is installed on the inner wall of the card slot, the pressure sensor 61 is installed at one end of the second spring 62, the alarm 63 and the controller 64 are both installed on the sleeve 32, and the pressure sensor 61 and the alarm 63 are both communicated with the controller 64.

[0032] In this embodiment, an elastic limit member 7 is installed on the kit 3, which abuts against the pressure warning member 6. The elastic limit member 7 includes a limit rod 71, a limit block 72 and a third spring 73. The limit rod 71 slides through the outer periphery of the sleeve 32 and is inserted into the card slot to abut against the pressure sensor 61. The limit block 72 is installed at the end of the limit rod 71 away from the pressure sensor 61. The third spring 73 is sleeved on the limit rod 71 and is located between the sleeve 32 and the limit block 72. The two ends of the third spring 73 are respectively connected to the sleeve 32 and the limit block 72. A socket adapted to the limit rod 71 is provided on the card block 44.

[0033] In this embodiment, the elastic clip 4 has two position states. When the elastic clip 4 is in the first position state, the elastic clip 4 does not abut against the pressure warning component 6. When the elastic clip 4 is in the second position state, when the middle part of the steel rope 1 breaks, the elastic clip 4 is inserted into the slot and abuts against the pressure warning component 6, and the elastic limiter 7 limits the elastic clip 4.

[0034] It should be noted that: when the middle part of the steel rope 1 breaks, the pontoon body 2 drives the first steel cable 5 to pull the connecting rod 41 on the sleeve 31, and the end block 42 connected to the connecting rod 41 approaches the sleeve 32, and the first spring 43 is deformed, and the clamping block 44 on the end block 42 is inserted into the clamping groove provided in the sleeve 32. When the clamping block 44 is inserted into the clamping groove, it presses the pressure sensor 61, pushes the pressure sensor 61 to move into the clamping groove and compresses the second spring 62. When the jack on the clamping block 44 corresponds to the limit rod 71, the pressure sensor 61 is pressed. Afterwards, under the elastic action of the third spring 73, the limit rod 71 can be inserted into the socket opened in the block 44 to complete the locking of the connecting rod 41. Under the action of the first steel cable 5 between the two sleeves 31, the broken ends of the steel rope 1 can be pulled to achieve the locking of the broken ends of the steel rope 1. This structure can respond quickly and effectively fix the two ends of the broken steel rope 1 through the pulling of the first steel cable 5 and the stretching and locking of the elastic clip 4, thereby preventing the pontoon body 2 from dispersing due to loss of connection, thereby avoiding possible safety accidents caused by this.

[0035] When the pressure sensor 61 is subjected to force, an early warning instruction can be sent to the alarm 63 through the controller 64, and a timely early warning can be issued through the alarm 63. The controller 64 can transmit the information of the force on the pressure sensor 61 to the cloud to remind the staff in time. This structure can trigger the early warning mechanism in time after the steel rope 1 breaks. The above early warning scheme can be realized under the existing technology.

[0036] In a specific embodiment, a second steel cable 8 is installed at the ends of the two sleeves 31 that are away from each other, and the two second steel cables 8 are respectively connected to the two floating bridge bodies 2 .

[0037] It should be noted that when the steel rope 1 breaks, the second steel rope 8 provided between the sleeve 31 and the floating bridge body 2 can play a pulling role, further preventing the floating bridge from dispersing and enhancing the pulling effect on the floating bridge.

[0038] In a specific embodiment, a cylindrical rubber 9 is embedded between the two floating bridge bodies 2 , and the cylindrical rubber 9 is sleeved on the steel rope 1 and the sleeve 3 . A cavity for placing the sleeve 3 is defined in the cylindrical rubber 9 .

[0039] It should be noted that the cylindrical rubber 9 is mainly used for force buffering to prevent the two floating bridge bodies 2 from colliding under the action of wind and waves.

[0040] In a specific embodiment, a connecting well 10 is provided on each of the two floating bridge bodies 2, and an assembly channel 11 connected to the connecting well 10 is provided inside the floating bridge body 2. The two ends of the steel rope 1 are respectively extended into the two assembly channels 11 and are installed with two screws 12. The two screws 12 extend into the two connecting wells 10 at one end away from each other, and nuts 13 are threadedly sleeved on the two screws 12. The two nuts 13 are respectively against the inner walls of the two connecting wells 10.

[0041] It should be noted that when disassembling the steel rope 1 , it is only necessary to unscrew the nut 13 on the screw rod 12 to pull the steel rope 1 out from between the two floating bridge bodies 2 , thereby completing the disassembly of the steel rope 1 .

[0042] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
