Description

Technical Field

[0001] The present invention relates to the technical field of cable laying protection, and in particular to a communication cable protection device and a protection method thereof. Background Art

[0002] Communication cables are generally laid underground or on a bridge. Especially when encountering railways, roads, elevated roads or roads inside factories, when using a bridge to lay the lines, it is necessary to prevent vehicles from colliding with the bridge when passing. Height limit signs or height limit fences are generally used for protection.

[0003] In actual application, when using height limit barriers, cable ducts are set on the height limit barriers, and communication cables are set inside the cable ducts. Although the height limit barriers can achieve a certain protection effect, there may be a phenomenon of over-height vehicles accidentally colliding with the bridge. Even if the height limit barriers are set, the height limit barriers are rigidly set, which will cause the bridge to deform during a collision. In severe cases, it will cause the bridge to topple. Whether the bridge is deformed or toppled, it will move relative to the cables, causing cable damage or even breakage.

[0004] Although adding vertical beams of a certain height to the height limit fence and setting the cable duct on the top of the vertical beam can prevent direct collision with the vehicle, setting it too high will lead to poor stability. When the height limit fence vibrates after a vehicle collision, the cable duct will still vibrate, and there is also a risk of tipping over. Therefore, the protection effect needs to be improved. Summary of the Invention

[0005] The object of the present invention is to solve the above problems and provide a communication cable protection device and a protection method thereof.

[0006] To achieve the above object, the technical solution of the present invention is: a communication cable protection device, comprising: uprights, including two arranged at intervals; A trigger assembly is provided on a side of the columns close to each other, comprising a first swing arm that rotates along a first axis and a trigger rod that penetrates the column and cooperates with the first swing arm. The lower end of the first swing arm is provided with an overlapping portion, and a touch member is provided above the two overlapping portions. The first axis is parallel to the spacing direction of the two columns. A locking assembly includes a locking member arranged to be horizontally guided along the first axis, the locking member being connected to the trigger rod; It also includes a lifting seat arranged on the top of the column. The lower surface of the lifting seat is provided with a locking rod that cooperates with the vertical guide of the column. The top of the lifting seat is used to set a wire groove.

[0007] Furthermore, the trigger assembly also includes a rotating member arranged to rotate coaxially with the trigger rod, the rotating member is connected to the swing arm in a transmission manner, an elastic member is arranged between the trigger rod and the column, and a limiting surface adapted to the limiting protrusion is provided on the outer peripheral surface of the trigger rod. The elastic member can provide elastic force to the trigger rod to abut against the limiting surface, and the limiting surface is provided with a first avoidance hole for the limiting protrusion to pass through.

[0008] Furthermore, the first swing arm and the rotating member gear are meshed with each other.

[0009] Furthermore, an edge plate is provided in the middle area of ​​the trigger rod, and a flange plate is provided at the end of the rotating part. The elastic part is a compression spring sleeved on the trigger rod, and the two ends of the compression spring are respectively in contact with the edge plate and the flange plate. The limiting surface is the side of the flange plate opposite to the rotating part.

[0010] Furthermore, the end of the trigger rod is non-rotatably fitted with an ear plate, which is hingedly connected to the locking member; and the hinged member is non-rotatably fitted with the column around the axis of the trigger rod.

[0011] Furthermore, there are two locking rods, and the locking assembly also includes a rigid locking arm, with two locking parts at both ends of the locking arm, each locking part is connected to a guide rod, and the column is provided with a guide part that cooperates with the two guide rods, and the ear plate cooperates with the locking arm pin shaft.

[0012] Furthermore, it also includes a support beam erected on the top of the two columns and located below the lifting seat, the end of the support beam is provided with a plug hole adapted to the locking rod, and a vertical rod is vertically provided above the touch member, and the top of the vertical rod is in contact with the support beam.

[0013] Furthermore, the vertical rod is elastically telescopically arranged along the axial direction.

[0014] Furthermore, it also includes a lifting unit, which includes a support arm vertically arranged on the top of the column, a first pulley arranged on the top of the support arm and a steel cable wound above the first pulley, one end of the steel cable is connected to the lifting seat, and the other end is connected to a pull-down member.

[0015] Furthermore, the present application also provides a communication cable protection method, which uses any of the above-mentioned communication cable protection devices, including the following steps: Step 1: The locking assembly is in an initial state of locking the locking rod. When the contact member is touched, the first swing arm is driven to swing, thereby triggering the assembly; Step 2: When the touch amplitude exceeds a predetermined value, the trigger assembly is triggered, and the trigger rod drives the locking member to move, switching from the initial state of locking the locking rod to the state of releasing the locking rod, at which time the lifting seat is released; Step 3: After the lifting seat is released, it rises to a certain height, driving the upper cable duct to move upward together. At the same time, the contact part is separated from the column by collision, reducing the further transmission of force and protecting the cables in the cable duct.

[0016] The communication cable protection device and protection method disclosed in the present invention have the following beneficial effects compared with the prior art: a wire trough can be set on the lifting base, and communication cables can be laid through the wire trough. During use, when a vehicle accidentally collides with the guardrail, it will first contact the guardrail, and when colliding with the guardrail, it will drive the first swing arm to swing, and when the first swing arm swings, it will drive the trigger component to move. After the trigger component is triggered, it will drive the locking card to move, and switch from the locked state of the clamping column to the state of releasing the clamping column. After the clamping column is released, the lifting seat will be raised to increase the height, thereby effectively reducing the probability of the wire trough and cable being collided, and effectively protecting the cable. Moreover, since the touch member and the overlapping portion are overlapped, after the collision, when the vehicle is too high, an upward force will be provided to the touch member, so that the touch member is separated from the first swing arm, thereby reducing the transmission of the collision force and effectively protecting the column.

DETAILED DESCRIPTION

[0040] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and thus only show components related to the present invention.

[0041] Example 1 refer to Figures 1-4 , as a specific implementation method, includes: Columns 21, including two arranged at intervals; The trigger assembly 20 is disposed on a side of the columns 21 that is close to each other, and includes a first swing arm 201 that rotates along a first axis and a trigger rod 203 that penetrates the column 21 and cooperates with the first swing arm 201. The lower end of the first swing arm 201 is provided with an overlapping portion 2010, and a contact member 22 is provided above the two overlapping portions 2010. The first axis is parallel to the spacing direction between the two columns 21. The locking assembly 25 includes a locking member arranged horizontally along the first axis and connected to the trigger rod 203; It also includes a lifting seat 33 arranged on the top of the column 21. The lower surface of the lifting seat 33 is provided with a locking rod 251 that cooperates with the vertical guide of the column 21. The top of the lifting seat 33 is used to set the wire trough 1.

[0042] Specifically, the technical solution of the present application is as follows: it includes two columns 21 arranged at intervals. Specifically, in actual application, the column 21 is made of steel, and a top plate 210 is welded on the top. The top plate 210 is arranged horizontally, and a through hole is provided on the top plate 210 to guide and plug in with the locking rod 251. The lifting seat 33 is a U-shaped structure, which is conducive to the setting of the wire trough 1. The locking rod 251 is fixedly arranged on the bottom surface of the lifting seat 33, and the lifting seat 33 can be lifted and lowered in the vertical direction. In actual application, the two columns 21 are arranged at intervals on both sides of the road, the trigger component 20 is arranged on the side where the columns 21 are close to each other, and the locking component 25 is arranged on the side where the columns 21 are far away from each other. The initial state is as follows Figure 1-4 As shown, the upper end of the first swing arm 201 is rotatably connected to the column 21, and the lower end is drooped under the action of gravity. At this time, the trigger assembly 20 is in a non-triggered state. At this time, the locking rod 251 passes through the top plate 210, and the lower end extends below the top plate 210. The lifting seat 33 is placed above the top plate 210. Figure 10 The lower end of the locking rod 251 is provided with a slot 2510, referring to Figure 11 The locking member is a locking card plate 250. The locking card plate 250 is provided with a U-shaped groove that is engaged with the card slot 2510. When the U-shaped groove is engaged in the card slot 2510, the locking card plate 250 cooperates with the axial limit of the card column. The locking card plate 250 and the lower surface of the top plate 210 are limited to lock the lifting seat 33. In the initial state, the locking card plate 250 locks the card column and is in a locked state. At this time, the lifting seat 33 is locked, which is convenient for setting the wire trough 1 In this way, the cable duct 1 is still set on the top of the column, which has good stability. A lap joint 2010 is provided at the lower end of the first swing arm 201, and a touch member 22 is overlapped on the lap joint 2010. The touch member 22 includes a rigid rod-shaped structure lap member 220 and a guardrail 221 provided on the lap member 220. The guardrail 221 extends to both sides and downward in a direction perpendicular to the lap member 220. Through the above setting method, the cable duct can be set on the lifting base. When the first swing arm 201 swings, the trigger assembly 20 is driven to move. After the trigger assembly 20 is triggered, the locking card plate 250 is driven to move, and the state of the clamping column is switched from the locked state to the state of the released clamping column. After the clamping column is released, the lifting seat 33 is raised to increase the height, thereby effectively reducing the probability of the cable trough 1 and the cable being collided, and effectively protecting the cable. Moreover, since the touch member 22 and the overlapping portion 2010 are overlapped, after the collision, when the vehicle is too high, an upward force is provided to the touch member 22, so that the touch member 22 is separated from the first swing arm 201, thereby reducing the transmission of the collision force and effectively protecting the column 21. It should be noted that the specific structure and working method of the trigger assembly 20 and the locking assembly are referred to below.

[0043] In some embodiments, the overlapping portion 2010 may be configured to have a mechanical strength lower than that of the first swing arm 201 . When the collision force is too large, the overlapping portion 2010 may be damaged, causing the contact member 22 to fall off and separate.

[0044] Furthermore, it can be understood that the contact member 22, by providing guardrails 221 extending to both sides and downward, can ensure that the vehicle can effectively apply force to the first swing arm 201 when colliding in two directions, and can ensure that the vehicle contacts the guardrail 221 first. At this time, the vehicle and the mounting member 220 are still at a certain distance. The vehicle continues to move, pushing the guardrail 221 to move and driving the mounting member 220 to move while driving the first swing arm 201 to rotate, driving the trigger component 20 to trigger, controlling the extension size of the guardrail 221, and ensuring that the trigger component 20 is triggered before the vehicle contacts the cable duct 1. After the trigger component 20 is triggered, the locking component 25 is driven to release. At this time, the lifting seat 33 is in a released state. At this time, even if the vehicle touches the cable duct 1, the cable duct 1 can avoid upward, reducing damage to the cable duct 1, thereby reducing damage to the cables laid inside.

[0045] Further, as a specific embodiment, refer to Figure 5-Figure 14 The specific structure of the trigger assembly 20 is as follows: the trigger assembly 20 also includes a rotating member coaxially rotatable with the trigger rod 203, the rotating member is transmission-connected to the swing arm, an elastic member is provided between the trigger rod 203 and the column 21, and a limiting surface adapted to the limiting protrusion 2031 is provided on the outer peripheral surface of the trigger rod 203. The elastic member can provide an elastic force to the trigger rod 203 to abut against the limiting surface, and the limiting surface is provided with a first avoidance hole 2060 for the limiting protrusion 2031 to pass through.

[0046] Specifically, a support shaft 213 and a cylinder 204 are provided on the side wall of the column 21, and a matching hole 2020 is provided on the upper end of the first swing arm 201 to rotate with the support shaft 213, and a rotating sleeve is provided on the end of the cylinder 204, wherein the trigger rod 203 is guided and matched with the cylinder 204, and the rotating sleeve is transmission-connected to the outer circumference of the matching hole 2020, and an elastic member is provided between the trigger rod 203 and the column 21, and the elastic member can provide elastic force to the trigger rod 203, so that the trigger rod 203 pushes the locking card 250 in the direction away from the clamping column, so that the trigger rod 203 can move in the direction of releasing the clamping column under the elastic force of the elastic member, and a limiting surface is provided on the cylinder 204, and a first avoidance hole 2060 is provided on the limiting surface, and a limiting protrusion 2031 that cooperates with the limiting surface is provided on the trigger rod 203. Figure 13When the first swing arm is hit and swung, the rotating sleeve can be driven to rotate, and the limiting surface can be rotated when the rotating sleeve rotates. When the rotating sleeve rotates 90°, the first avoidance hole 2060 corresponds to the limiting protrusion 2031. At this time, under the elastic force of the elastic member, the trigger rod 203 can be pushed to move, and the locking card 250 can be pushed to switch the state, so that the locking assembly 25 is switched to the released state, and is kept in the released state under the elastic force of the elastic member. At this time, the lifting seat 33 can be lifted, driving the cable trough 1 and the communication cable to rise, achieving a protective effect.

[0047] Further, as a preferred embodiment, refer to Figure 11-14 The first swing arm 201 meshes with the gear of the rotating member. To ensure that the first swing arm 201 can effectively drive the trigger assembly 20 to operate, transmission teeth are provided on the outer circumference of the rotating sleeve to form a second gear 205. Teeth provided on the outer circumference of the matching hole 2020 that mesh with the second gear 205 form the first gear 202. Through gear transmission, reliability is improved.

[0048] Preferred, reference Figure 11 The radius of the first gear 202 is greater than the radius of the second gear 205, and the transmission ratio of the first gear 202 to the second gear 205 is 1.5-3. Through this setting, the sensitivity of the trigger component 20 to be triggered can be improved.

[0049] Further, as a specific implementation method, continue to refer to Figure 11-14 An edge plate 2030 is provided in the middle area of ​​the trigger rod 203, and a flange plate 206 is provided at the end of the rotating part. The elastic part is a compression spring 207 sleeved on the trigger rod 203, and the two ends of the compression spring 207 are respectively in contact with the edge plate 2030 and the flange plate 206. The limiting surface is the side of the flange plate 206 opposite to the rotating part.

[0050] Specifically, one end of the cylinder 204 close to the locking card plate 250 is guided and matched with the locking rod 251, and an edge plate 2030 is integrally provided in the middle area of ​​the locking rod 251, and the edge plate 2030 is guided and matched with the cylinder 204, wherein the edge plate 2030 is a breathable plate to ensure that the trigger rod 203 can move freely axially in the cylinder 204, and the elastic member is a compression spring 207. In this way, the structure can be simplified, and the space in the cylinder 204 can be effectively utilized, and the structure is more reasonable. As a preferred embodiment, the end of the first gear 202 is detachable and coaxially provided with a flange plate 206, and the middle area of ​​the flange plate 206 is provided with a through hole that guides and cooperates with the trigger rod 203, and the limiting surface is the plate surface of the flange plate 206. As a preferred embodiment, the size of the first avoidance hole 2060 is larger than the size of the limiting protrusion 2031, thereby facilitating the passage of the limiting protrusion 2031.

[0051] Further, as another embodiment, referring to Figure 14-16 Between the flange plate 206 and the compression spring 207, an extrusion piece 208 is also sleeved on the trigger rod 203. The extrusion piece 208 is provided with a guide channel 2081 through which the cylinder trigger rod passes. The outer circumference is provided with a strip-shaped rib 2080. The inner circumference of the cylinder 204 is provided with a key groove 2040 for axial guidance and circumferential limitation of the rib 2080. The extrusion piece 208 is provided with a second avoidance hole 2082 corresponding to the first avoidance hole 2060. The plate surface of the flange plate 206 is provided with an arc-shaped protrusion, the end face of the arc-shaped protrusion is a driving inclined surface 2061, and the extrusion piece 208 is provided with an arc-shaped groove adapted to the arc-shaped protrusion. The bottom of the arc-shaped groove is a matching inclined surface 208 that drives and cooperates with the driving inclined surface 2061. 3. The flange plate 206 is provided with a driving inclined surface 2061 that mates with the mating inclined surface 2083. With this arrangement, in the initial state, the arcuate protrusion extends into the arcuate groove, and under the elastic force of the compression spring 207, the extrusion member 208 abuts against the flange plate 206. When the first gear 202 is driven to rotate, the extrusion member 208 does not rotate. The driving inclined surface 2061 can drive the mating inclined surface 2083, thereby pushing the extrusion member 208 to move a certain distance, thereby increasing the extrusion amplitude of the compression spring 207 and the elastic force, thereby providing greater elastic force to the trigger lever 203 and applying greater elastic force to the locking plate 250, effectively pushing the locking plate 250 to the released state. Preferably, two arcuate grooves and two arcuate protrusions are provided symmetrically about the axis of the trigger lever 203.

[0052] Furthermore, as a specific embodiment, it can be understood that when the trigger assembly 20 is working, the second gear 205 needs to rotate, and the trigger rod 203 needs to be arranged in a circumferential non-rotational manner, so that the trigger rod 203 and the second gear 205 can rotate relative to each other and switch from the initial state to the trigger state. The end of the trigger rod 203 is non-rotatably equipped with an ear plate 2032, and the ear plate 2032 is hingedly connected to the locking member; around the axis of the trigger rod 203, the hinge is non-rotatably equipped with the column 21.

[0053] Further, as a specific embodiment, refer to Figure 11 、 Figure 12 、 Figure 21 The locking assembly further comprises a rigid locking arm 252, each end of which is provided with two locking members, each of which is connected to a guide rod 2501. The upright 21 is provided with a guide portion 2100 that cooperates with the two guide rods 2501, and a lug 2032 is pin-engaged with the locking arm 252. Specifically, the trigger rod 203 is detachably connected to one end of the lug 2032, which non-rotatably engages with the trigger rod 203. This engagement adopts the existing technology and will not be described in detail here. The locking assembly includes a plate-shaped locking arm 252, and locking clips 250 are provided at both ends of the locking arm 252. The locking clips 250 are slidably matched with the lower surface of the top plate 210. A pin hole is provided in the middle area of ​​the locking arm 252, and the ear plate 2032 is connected to the pin hole through a pin shaft. Each locking clip 250 is provided with a guide rod 2501, and a guide portion 2100 that cooperates with the guide rod 2501 is provided on the lower surface of the top plate 210. Through the cooperation of the guide portion 2100 and the guide rod 2501, the locking arm 252 is set horizontally and cannot rotate, thereby circumferentially limiting the trigger rod 203 through the pin shaft. This setting method can not only limit the trigger rod 203 circumferentially, but also guide the locking arm 252, which is conducive to state switching of the locking clip 250.

[0054] Further, as a specific embodiment, refer to Figures 1-6 、 Figure 10 The communication cable protection device provided in the present application also includes a support beam 23 erected on the top of the two columns 21 and located below the lifting seat 33. The end of the support beam 23 is provided with a plug hole adapted to the locking rod 251. A vertical rod 222 is vertically provided above the touch member 22, and the top of the vertical rod 222 is in contact with the support beam 23.

[0055] Specifically, it is understood that in order to improve the supporting effect of the wire trough 1, a support beam 23 is further provided. Both ends of the support beam 23 are provided with through holes that cooperate with the locking rod 251. Through this arrangement, the two ends of the support beam 23 are overlapped on the two top plates 210, and then the lifting seat 33 is placed on the support beam 23. The locking rod 251 passes through the support beam 23 and the top plate 210 to position the support beam 23. Since the touch member 22 is set on the mounting part through the mounting member 220, the touch member 22 may fall in the event of strong wind or slight collision. In order to improve the stability of the touch member 22, a vertical rod 222 is fixed on the upper surface of the mounting member 220. The upper end of the vertical rod 222 abuts against the lower end of the support beam 23, thereby providing a vertical limiting force for the mounting member 220 and improving stability.

[0056] Furthermore, as a specific embodiment, the vertical rod 222 is set to be elastically telescopic along the axial direction. By setting the vertical rod 222 to be axially elastic, when the mounting member 220 is collided, when the vehicle applies an upward force to the mounting member 220, the vertical rod 222 can be axially compressed to ensure that the mounting member 220 can be effectively separated from the first swing arm 201.

[0057] Example 2 The present application provides a communication cable protection device. Further, in the present application, the device also includes a lifting unit 3, which is used to provide a lifting power for the lifting seat 33 to rise. After the trigger component 20 is triggered, the lifting seat 33 is driven to rise. The specific structure is as follows: Figures 17-22 The lifting unit 3 includes a support arm 31 vertically arranged at the top of the column 21, a first pulley 34 arranged at the top of the support arm 31 and a steel cable 32 wound above the first pulley 34, one end of the steel cable 32 is connected to the lifting seat 33, and the other end is connected to a pull-down member.

[0058] Specifically, the support arm 31 includes two symmetrically arranged on both sides of the column 21, each support arm 31 is connected to the side of the column 21 through a connecting plate, the top of the column 21 is higher than the top plate 210, and the height difference between the two is 50cm-1m. At least one first pulley 34 is provided on the column 21, and the axis of the first pulley 34 is parallel to the first axis. The steel cable 32 is wound around the top of the first pulley 34, one end is fixedly connected to the lifting seat 33, and the other end is provided with a pull-down member, which provides tension for the rope through the pull-down member, thereby providing lifting force for the lifting seat 33. As a specific embodiment, the pull-down member can be a counterweight 30, which provides a downward pulling force through the gravity of the counterweight 30. The pull-down member can also be a tension spring, etc. Through the above-mentioned setting method, when the locking assembly 25 is in the locked state, the locking rod is locked, and the lifting seat 33 does not rise at this time. After release, it is pulled up by the pull-down member.

[0059] Specifically, the counterweight 30 can be made of concrete, with a hanging piece 301 made of steel bars cast integrally therewith, and the hanging piece is fixedly connected to the two steel cables 32 .

[0060] Further, as a preferred embodiment, refer to Figures 18-20 Two first pulleys 34 are arranged on the support arm 31 at intervals, and two second pulleys 35 are rotatably arranged on the lower surface of the top plate 210. The two steel cables 32 arranged on each column 21 pass around the two first pulleys 34 and then pass over the second pulleys 35 and are connected to a pull-down member. A pull-down member provides downward pulling force for the two steel cables 32, thereby simplifying the structure.

[0061] Furthermore, it is understandable that when the lower pull-down member continuously provides a downward pulling force for the lifting seat 33, when the locking card plate 250 locks the card slot 2510 of the locking rod 251, under the pulling force of the lower pull-down member, the force between the locking card plate 250 and the card slot 2510 will be too large, resulting in excessive local force between the two and causing friction. Under the action of vibration for a long time, the contact area between the two will be damaged, further increasing the friction. The friction will delay and hinder the switching component from driving the locking component 25 to switch the state, which will reduce the switching efficiency and even hinder the state switching. In order to avoid the above phenomenon as much as possible, In a preferred embodiment, a hanging ring 302 is provided at the position where the two steel cables 32 are connected, a support frame 212 is provided on the side wall of the column 21, a rotating shaft 2140 is rotatably provided on the support frame 212, a sleeve is provided on the rotating shaft 2140, the sleeve and the rotating shaft 2140 are non-rotatably matched through a spline, a hanging column 214 is provided on the outer circumference of the sleeve along the radial direction, and a second swing arm 215 is non-rotatably matched at both ends of the rotating shaft 2140, and a rolling element 2150 is provided on the top of the second swing arm 215, and the axis of the rolling element 2150 and the axis of the rotating shaft 2140 are both horizontally arranged and perpendicular to the trigger rod 203. Figure 19 、 Figure 21 、 Figure 22 , is a structural diagram of the hanging column 214 when it is in the hanging state. At this time, the angle α between the axis of the hanging column 214 and the axis of the trigger rod 203 is 2°-3°, and the angle β between the length direction of the second swing arm 215 and the vertical direction is 3°-5°. At this time, the rolling element 2150 is in contact with the lower surface of the locking arm 252. The locking arm 252 provides a downward force to the rolling element 2150 in the vertical direction through the support of the guide rod 2501 and the locking card 250, so that the second swing arm 215 is kept in position. At this time, the hanging ring 302 can be hung on the hanging column 214. At this time, the pull-down member does not apply tension to the steel cable 32, so that the state can be switched freely between the locking card 250 and the card slot 2510.

[0062] And reference Figure 11 、 Figure 12The locking arm 252 has a limited size along the axial direction of the trigger rod 203. When in the locked state, the locking arm 252 can contact and limit with the rolling element 2150. When the trigger assembly 20 is triggered, the trigger rod 203 pushes the locking arm 252 to move, and the locking arm 252 and the second swing arm 215 move relative to each other to control the size of the locking arm 252. When the locking card plate 250 and the card slot 2510 are completely separated by more than half, the locking arm 252 completely passes through the rolling element 2150. At this time, under the pulling force of the lower pull member, the hanging column 214 is pulled downward to swing, driving the second swing arm 215 to swing. After the second swing arm 215 swings, it can further push the locking arm 252, which is conducive to quickly pushing the locking arm 252 to drive the locking card plate 250 to separate from the locking rod 251, further improving the switching speed.

[0063] Example 3 The present application also provides a communication cable protection method, which uses any of the above-mentioned communication cable protection devices, including the following steps: Step 1: The locking assembly is in the initial state of locking the locking rod 251. When the touch member 22 is touched, the first swing arm 201 is driven to swing, and the trigger assembly 20 is linked; Step 2: When the touch amplitude exceeds a predetermined value, the trigger assembly 20 is triggered, and the trigger rod 203 drives the locking member to move, switching from the initial state of locking the locking rod 251 to the state of releasing the locking rod 251, at which time the lifting seat 33 is released; In step three, after the lifting seat 33 is released, it rises to a certain height, driving the upper cable duct 1 to move upward together, and at the same time, the touch piece 22 is separated from the column 21 by the collision, reducing the further conduction of force, and protecting the cables in the cable duct 1. Specifically, a cable protection device provided by the present application can protect the cables by the above method when in use. When a vehicle accidentally collides, it will first contact the guardrail 221. When colliding with the guardrail 221, it will drive the first swing arm 201 to swing. When the first swing arm 201 swings, it will drive the trigger assembly 20 to move. After the trigger assembly 20 is triggered, it will drive the locking card 250 to move, switching from the locked state of the clamping column to the state of releasing the clamping column. After the clamping column is released, the lifting seat 33 will be lifted and the height will be increased, thereby effectively reducing the probability of the cable duct 1 and the cable being collided, and effectively protecting the cable.

[0064] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
