In addition, the cable area usually belongs to the LPZ0 (direct lightning protection zone) lightning protection zone. The outermost layer of the bridge cable is usually covered with a PE (polyethylene) layer or rubber anti-corrosion wrapping tape and other covering layers. Various equipment fixed on the bridge cables are at risk of direct or side lightning strikes.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of this application, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of this application without making any creative efforts are within the scope of protection of this application.

[0041] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0042] On the one hand, if Figure 1 and Figure 2 As shown, the present application provides a bridge cable attachment installation device, including a fixed connection component 1 and a accommodating shell 2. The fixed connection component 1 is provided with at least one, which is used to connect with the bridge cable body 3. The accommodating shell 2 is connected to the fixed connection component 1 for placing the device module 5.

[0043] Specifically, each of the above-mentioned fixed connection components 1 includes a connecting member 11, a main member 12 and a cantilever 13. The connecting member 11 includes multiple sections of clamping plates 111 hinged end to end along the length direction, which are used to be mounted on the outside of the above-mentioned bridge cable body 3; the main member 12 is connected to the side wall of any of the above-mentioned clamping plates 111 away from the above-mentioned bridge cable body 3; one end of the cantilever 13 is rotatably connected to the above-mentioned connecting member 11, and the other end of the above-mentioned cantilever 13 is used to connect the anti-fall and discharge cable 4 to adjust the balance of the above-mentioned main member 12 on the bridge cable body 3; the accommodating shell 2 is connected to the above-mentioned main member 12.

[0044] It is understood that the multiple segments of the clamping hoop 111 are hinged end to end, so the number of clamping hoop 111 can be specifically set according to the diameter of the bridge cable body 3 to adapt to different bridge cable bodies. On the other hand, the multiple segments of the hinged clamping hoop 111 connected end to end to form a ring can also better fit the bridge cable body 3, and compared with a one-piece ring clamp, the friction between the clamping hoop and the bridge cable body 3 is greater. When the connector 11 is installed outside the bridge cable body 3, the cantilever 13 and the main body 12 are respectively located on either side of the bridge cable body 3. At this time, the cantilever 13 is located on the connector 11 and is aligned with the main body 12. The angle of the main body 12 relative to the axis of the anti-fall and leakage cable 4 is adjusted by the cantilever 13, thereby preventing the connector 11 from slipping or rotating on the bridge cable body 3 due to the gravity of the device module 5 after the device module 5 is installed in the accommodating housing 2. By adjusting the angles between the cantilever 13 and the anti-falling and leakage attachment cable 4 and the bridge cable body 3 , the torque is changed to level the main body 12 and the device module 5 installed on the main body 12 .

[0045] It should be noted that one end of the anti-falling and leakage attachment cable 4 is connected to the upper anchor head 10, and the other end is connected to the ground or the bridge deck, serving as a grounding down conductor. The device module 5 can be a lighting module, a cable force meter electronic control module, an ice melting device module, etc., and the corresponding module is installed on the housing 2 according to the needs of the bridge cable body 3. The device module 5 is installed on the bridge cable body 3 by fixing the connection component 1, so that units with different functions can be modularized and different modules can be matched and installed flexibly according to needs. When the unit module is damaged, it is only necessary to remove the device module on the housing 2 for maintenance, which makes operation and maintenance more convenient. On the other hand, by providing the cantilever 13, not only can the connecting member 11 be prevented from sliding down and rotating on the bridge cable body 3 due to gravity after the device module 5 is installed, but the anti-falling and leakage attachment cable 4 is used to connect with the connecting member 11, thereby solving the problem that similar devices in the LPZ0 lightning protection zone have no leakage channel.

[0046] In some optional embodiments, a mounting hole for engaging with the device module 5 is provided in the accommodating shell 2 to facilitate installation and disassembly.

[0047] In some optional embodiments, the connecting member 11 further includes a locking member, which is disposed between two adjacent clamping plates 111 to detachably connect the two clamping plates 111 .

[0048] Take the embodiment of this application as an example to explain in detail. Figure 2 As shown, the connecting member 11 includes four first clamping pieces with a first set curvature and one second clamping piece with a second set curvature. The above-mentioned first clamping pieces and the second clamping pieces are connected in series in sequence along the length direction. The above-mentioned locking member is hinged to any one of the first clamping pieces and is detachably connected to the adjacent first clamping piece. The above-mentioned main body 12 is connected to the side wall of the second clamping piece away from the bridge cable body 3.

[0049] The purpose of such a setting is to facilitate installation and removal between the device and the bridge cable body 3, and the locking member cooperates with a plurality of mutually hinged clamping plates 111, thereby facilitating adjustment of the tightness between the connecting member 11 and the bridge cable body 3.

[0050] In other embodiments, the number of the first clamping hoop pieces and the second clamping hoop pieces, and the sizes of the first set arc and the second set arc are specifically set according to the diameter of the bridge cable body 3, and are not limited here.

[0051] In some optional embodiments, the locking member includes a connecting portion and a locking portion. One end of the connecting portion is hinged to any clamping piece 111, and the other end is clamped to another clamping piece 111 and secured by the locking portion. In other embodiments, the locking member can also be a fixed pin that simultaneously passes through two adjacent clamping pieces 111 to fix the relative position between the two clamping pieces, and connects multiple clamping pieces 111 to form a ring structure.

[0052] In some optional embodiments, the locking member includes a shell 112, a connecting belt 113 and a fixing portion. The connecting belt 113 is connected between two adjacent clamping plates 111 and is partially located in the shell 112. A fixing portion is provided in the shell 112, and the length of the connecting belt 113 in the shell 112 can be adjusted and fixed, so that the two clamping plates 111 connected at both ends of the connecting belt 113 are pulled closer or farther away from each other to adjust the length of the entire connecting member 11.

[0053] Specifically, such as Figure 6As shown, in this example, the connecting strap 113 has a set length and can be bent arbitrarily, so it can be made of a material with a certain strength, such as a chain or steel wire. The shell 112 is provided with through holes for the two ends of the connecting strap 113 to pass through. The fixed portion includes a baffle 114 and a movable latch 115, both of which are located within the shell 112. The baffle 114 is fixedly connected to the shell 112, and the movable latch 115 is detachably connected to the shell 112. The movable latch 115 and the through hole are respectively located on either side of the baffle 114. By inserting movable latches 115 of different diameters between the connecting strap 113 and the movable latch 115, the length of the connecting strap 113 on the side of the baffle 114 away from the through hole can be adjusted and fixed, thereby pulling the clamping plate 111 connected to the two ends of the connecting strap 113 in or out, thereby adjusting the length of the entire connecting member 11.

[0054] Preferably, two spaced apart fixing columns 116 are provided on one side of the baffle 114 close to the through hole, and the abutment points between the fixing columns 116 and the connecting belt 113, and the abutment points between the movable latch 115 and the connecting belt 113, are respectively located on both sides of the radial direction of the connecting belt 113, so that the connecting belt 113 is wrapped around the fixing columns 116 and the movable latch 115.

[0055] The advantage of this arrangement is that the fixed column 116 is used to provide a supporting force and a friction force for the connecting belt 113, and the winding path of the connecting belt 113 is limited, so that the two ends of the connecting belt 113 are close to each other to increase the contact area between the connecting belt 113 and the movable latch 115, thereby improving the friction force between the connecting belt 113 and the movable latch 115.

[0056] Preferably, one end of the cantilever 13 is rotatably connected to the locking member to facilitate leveling of the connecting member 11 during installation.

[0057] In some optional embodiments, two of the above-mentioned fixed connection components 1 are provided at intervals along the length direction of the above-mentioned bridge cable body 3, and the above-mentioned accommodating shell 2 is detachably connected to the two above-mentioned fixed connection components 1.

[0058] It will be appreciated that the housing 2 has a set length along the length of the bridge cable body 3, so that multiple different device modules 5 can be installed sequentially along the length of the bridge cable body 3, or device modules 5 of a set length can be installed on the bridge cable body 3. Therefore, to ensure that the device modules 5 are stably installed on the bridge cable body 3, in the embodiment of the present application, two fixed connection assemblies 1 are provided. In other embodiments, the number of fixed connection assemblies 1 may not be specifically set and may be specifically set according to the length of the housing 2.

[0059] Preferably, the length of the accommodating shell 2 is less than or equal to 2 m.

[0060] In some optional embodiments, a plurality of slots 24 for installing device modules 5 are provided at intervals on the accommodating shell 2, so as to gather a plurality of different modules into one accommodating shell 2. The number of slots 24 can be flexibly configured according to the scale of the project, which not only improves the integrity of the system and meets different installation requirements, but also facilitates system maintenance.

[0061] In some optional embodiments, the main body 12 is further provided with a mutually isolated strong-current wiring chamber 121 and a weak-current wiring chamber 122 , and the strong-current wiring chamber 121 and the weak-current wiring chamber 122 are electrically isolated by a strong-current and weak-current isolation net 123 .

[0062] A strong current wiring chamber 121 and a weak current wiring chamber 122 are provided on the main body 12, with the purpose of allowing the control unit for the control device module 5 to be installed on the accommodating shell 2 at the same time, and electrically isolating the strong current wiring chamber 121 and the weak current wiring chamber 122 through the strong and weak current isolation net 123, so that a three-phase four-wire power supply cable can be laid in the main body 12 to improve the voltage drop performance, while reducing the number of power supply lines, and the number of control signal lines does not need to be parallel, which makes it easy to meet the requirements of the metal wire trough laying specifications, simplifies the number of parallel cables, improves the safety of the circuit, avoids the problems of mixing of strong and weak electricity, uncontrolled temperature rise in the trough, and facilitates circuit maintenance.

[0063] It can be understood that the device module 5 or control unit installed on the accommodating shell 2 is electrically connected to the cables located in the high-voltage wiring chamber 121 and the low-voltage wiring chamber 122 through branch lines, wherein the high-voltage wiring chamber 121 is used to place the main power supply cable, and the low-voltage wiring chamber 122 is used to place the control cable.

[0064] In some optional embodiments, the accommodating shell 2 is provided with an anti-fall ring 21 , which is used to connect with the anti-fall and discharge cable 4 through a connecting chain 6 .

[0065] The connecting chain 6 further prevents the accommodating shell 2 and the device module 5 placed in the accommodating shell 2 from falling, thus playing a secondary fall prevention role.

[0066] In some optional embodiments, the accommodating shell 2 is provided with a wiring hole communicating with the high-voltage wiring chamber 121 and the low-voltage wiring chamber 122 .

[0067] It can be understood that, according to different device modules 5 , corresponding branch lines are separated from the cables in the high-voltage wiring chamber 121 and the low-voltage wiring chamber 122 , pass through the branching holes into the accommodating shell 2 and are electrically connected to the corresponding device modules 5 .

[0068] In some optional embodiments, a control terminal box 22 and a power terminal box 23 are further provided in the accommodating shell 2 . The control terminal box 22 is close to the weak-current wiring chamber 122 , and the power terminal box 23 is close to the strong-current wiring chamber 121 .

[0069] In some optional embodiments, the outer edge of the main body 12 is in an arc shape extending toward the clamping piece 111 .

[0070] It can be understood that the main body 12 and the outer structural line of the clamping plate 111 are formed into one piece. The purpose of this arrangement is to reduce the impact of wind resistance on the device when installed on the bridge cable body 3. If necessary, it needs to be finalized after wind tunnel testing.

[0071] In some optional embodiments, an inner wall of each of the clamping plates 111 that contacts the bridge cable body 3 is provided with an anti-slip substrate 117 .

[0072] The anti-slip substrate 117 can be made of an anti-slip rubber member to increase the friction between the clamping piece 111 and the bridge cable body 3, thereby improving the connection stability between the connecting piece 11 and the bridge cable body 3.

[0073] In some optional embodiments, the outer side wall of the main body 12 is provided with a slot, and the accommodating shell 2 is provided with a limiting protrusion that engages with the slot.

[0074] It can be understood that the accommodating shell 2 and the main body 12 are detachably connected by snapping, which facilitates replacement and maintenance of the accommodating shell 2. At the same time, the circuits in the main body 12 can be inspected by removing the accommodating shell 2, thereby improving the efficiency and convenience of inspection.

[0075] On the other hand, Figure 3 and Figure 4 As shown, the present application also provides a collective assembly of bridge cable attachments, including a fixed connection assembly 1, a accommodating shell 2 and an anti-falling and leakage attachment cable 4. The fixed connection assembly 1 is provided with at least one, which is used to be connected to the bridge cable body 3. The accommodating shell 2 is detachably connected to the fixed connection assembly 1 and is used to place a device module 5. The anti-falling and leakage attachment cable 4 is used to be spaced apart from the above-mentioned bridge cable body 3. The above-mentioned anti-falling and leakage attachment cable 4 is connected to the cantilever 13 and is used to be a grounding down conductor as a leakage channel during a lightning strike.

[0076] Specifically, the above-mentioned fixed connection assembly 1 includes a connecting member 11, a main member 12 and a cantilever 13. The connecting member 11 includes multiple sections of clamping plates 111 hinged end to end along the length direction, which are used to be mounted on the outside of the above-mentioned bridge cable body 3; the main member 12 is connected to the side wall of any of the above-mentioned clamping plates 111 away from the above-mentioned bridge cable body 3; one end of the cantilever 13 is rotatably connected to the above-mentioned connecting member 11 at a leveling position relative to the main member 12, and the other end of the above-mentioned cantilever 13 is used to connect the anti-fall discharge cable 4 to adjust the angle of the above-mentioned main member 12 relative to the axis of the anti-fall discharge cable 4, so that the main member 12 maintains balance on the bridge cable body 3 and avoids rotation on the bridge cable body 3; the accommodating shell 2 is detachably connected to the above-mentioned main member 12; the anti-fall discharge cable 4 is spaced apart from the above-mentioned bridge cable body 3, and the above-mentioned anti-fall discharge cable 4 is connected to the cantilever 13, which is used for grounding the down conductor as a discharge channel during lightning strikes.

[0077] In this case, the anti-falling and leakage cable 4 is made of hot-dip galvanized steel strands, each strand has a diameter of not less than 1.7 mm and a total cross-section of not less than 50 mm. 2 One end of the steel strand is used to connect to the upper anchor head 10 of the sling or cable, and the other end of the steel strand is used to connect to the bridge deck or the ground.

[0078] In other embodiments, the anti-falling and leakage current attachment cable 4 may be made of a material that meets the electrical performance requirements of leakage current and has sufficient structural strength, and no specific limitation is made here.

[0079] As can be seen, since the bridge cable body 3 is typically covered with a bridge cable body sheath 31, usually made of PE (polyethylene) or rubber anti-corrosion wrapping tape, various equipment fixed to the bridge cable is at risk of direct or side lightning strikes. The anti-fall discharge cable 4 not only serves as a grounding down conductor, but also as a secondary anti-fall anchor line.

[0080] As Figure 5The working principle of the present application is specifically explained by taking the embodiment shown as an example: the number and curvature of the corresponding clamping pieces 111 are set according to the diameter of the bridge cable body 3, and the two connecting parts 11 are set at a distance and sleeved on the position of the bridge cable body 3 where the lamp needs to be installed and stably connected by using a locking piece, and the cantilever 13 is sleeved on the anti-fall and leakage cable 4 and fixed, the high-voltage cable for power supply is passed through the high-voltage wiring chamber 121, and the control cable for control is passed through the low-voltage wiring chamber 122, and the corresponding cables are separated into corresponding branch lines 7 through the branching holes and electrically connected to the lamp module 51 and the control module 52 on the accommodating shell 2 respectively, the two ends of the accommodating shell 2 are respectively clamped on the two main parts 12, and connected to the anti-fall and leakage cable 4 through the connecting chain 6, further preventing the accommodating shell 2 from falling, and the control module 52 and the lamp module 51 are installed on the accommodating shell 2 at the required intervals to achieve the purpose of installing liquid crystal lighting fixtures on the bridge cable body 3.

[0081] The present invention provides a bridge cable body attachment installation device and a collection assembly of bridge cable body attachments. By arranging a mutually isolated strong-current wiring chamber and a weak-current wiring chamber on the main body, both the DC power supply and the controller unit can be installed. This not only solves the problem of unsafe mixed installation of strong and weak electricity and the problem of complicated and difficult-to-identify power supply lines, but also facilitates operation and maintenance, meets the requirements of metal wire duct laying specifications, improves the safety of the circuit, avoids the problems of mixed strong and weak electricity, uncontrolled temperature rise in the duct, etc.; the cantilever is used to connect the connector to the anti-fall and leakage cable, and one end of the anti-fall and leakage cable is connected to the upper anchor head of the bridge cable body, which not only further fixes the relative position of the device on the bridge cable body, avoids the problem of the device loosening and falling and rotating due to gravity imbalance, but also can use the anti-fall and leakage cable as a connection The ground down conductor solves the problem of no discharge channel when the device module is in a lightning protection zone; a container shell is used to place different device modules, and the container shell is detachably connected to the connector of the fixed connection component, so that multiple device modules can be integrated on one device, and different modules can be configured according to different project needs, and can be flexibly matched, and the fixed connection component does not need to be disassembled during maintenance, which is convenient for later maintenance and operation; the connector includes multiple sections of clamping plates hinged at the end along the length direction, so that the connection between the connector and the bridge cable body can be more stable, and the number of clamping plates can be adjusted to adapt to bridge cables of different diameters, thereby increasing the scope of use; by setting the outer edge of the above-mentioned main body to an arc shape extending toward the above-mentioned clamping plate, not only the integrity of the device is improved, but also the influence of wind resistance on the device is reduced.
