Description

TECHNICAL FIELD

[0001] The present application relates to the field of cable laying device, in particular to a cable fixing mechanism, a locking mechanism, a cable laying device and a method thereof. BACKGROUND

[0002] Optical cable monitoring has the advantages of real-time online monitoring, no electricity, no electromagnetic interference, high temperature and pressure resistance, corrosion resistance, high measurement accuracy, fast response speed, series connection and long transmission distance. Due to its efficient and stable monitoring ability and high precision, optical cable monitoring has been widely used in many fields such as geological disasters, oil and gas pipelines, tunnels and bridges in recent years, especially in the field of geological engineering.

[0003] Optical cable monitoring can be used to monitor the temperature, strain and disturbance of geological structure to characterize the health status of the geological structure. In order to realize the state monitoring of the geological structure, the optical cable needs to be laid in the geological structure. However, due to the small diameter, low strength and easy damage of the fiber core of the optical cable, it is difficult to lay the optical cable in the deep hole without breaking or damaging the fiber. Generally, there are several conventional laying devices and methods as follows:

[0004] First, the optical cable is tied on the steel cage, and then the steel cage is fixed and installed in the groove. However, this method needs to pre-drill a groove in the soil structure, and the measurement data of the optical cable reflected on the steel will cause errors in the measurement data.

[0005] Second, the optical cable is connected to the weight, and the weight is sunk into the deep hole drilled in the geological structure by the gravity of the weight. However, this method has the problem that the weight is difficult to control during the lowering process, and the optical cable is easy to collide with the hole wall, causing damage or winding of the optical cable.

[0006] Third, the optical cable is tied to the guard hammer, and the guard hammer is fixedly connected with the insertion rod. The insertion rod is used to press the guard hammer with the optical cable into the deep hole. However, in order to keep the position of the guard hammer unchanged in the deep hole, the insertion rod needs to be left in the deep hole. When the depth of the deep hole is large, the strength and length of the insertion rod are required to be large, and the laying cost is high.

[0007] The above laying methods and devices are not convenient for positioning and laying the optical cable in the deep hole, and the cost is high. SUMMARY

[0082] Referring to Figures 1 to 12 , the present application provides a cable fixing mechanism 2000 for fixing a cable 500 in a deep hole. The cable 500 can be a sensing optical cable for monitoring strain or temperature change of soil, and more particularly can be an armored distributed optical cable. The cable fixing mechanism 2000 comprises a loading component 100 for assembling the cable 500 to be pulled into the deep hole, and a positioning component 200 arranged on the loading component 100. The positioning component 200 comprises an anchor jaw member 220 and a transmission assembly 260 in driving connection with the anchor jaw member 220 for driving the anchor jaw member 220 to reciprocally switch between a retracted state 221 and an open state 222. The anchor jaw member 220 is used to grab the sidewall of the deep hole to play a fixing role when in the open state 222. The positioning component 200 is formed with a locking matching portion capable of locking matching with a locking mechanism 3000, so as to make the anchor jaw member 220 stop at the retracted state 221. The positioning component 200 can be arranged above the loading component 100, or can be arranged below the loading component 100, which is not specifically limited here. Preferably, the positioning component 200 is arranged above the loading component 100, and the positioning component 200 is fixedly connected with the loading component 100. The anchor jaw member 220 can be arranged on one side of the positioning component 200, or can be arranged on both sides of the positioning component 200, which is not specifically limited here. More preferably, the anchor jaw member 220 is arranged on both sides of the positioning component 200, so as to ensure that the anchor jaw member 220 has sufficient gripping force to position the cable 500.

[0083] Referring to Figure 1 and Figure 2 , the positioning component 200 further comprises a frame body 210, and the anchor jaw member 220 and the transmission assembly 260 are movably arranged on the frame body 210. The frame body 210 can be a housing with a receiving cavity, or can be a bracket with mounting points of the anchor jaw member 220 and the transmission assembly 260, which is not specifically limited here.

[0084] Referring to Figure 1 , Figure 2 and Figure 21The transmission assembly 260 comprises a transmission member 230 and a reset member 240. The transmission member 230 is movably arranged on the frame 210 and is in transmission connection with the anchor member 220. The transmission member 230 is configured to move reciprocally between a first position 231 and a second position 232 to drive the anchor member 220 to switch reciprocally between the retracted state 221 and the open state 222. The reset member 240 is arranged on the frame 210 and is connected with the transmission member 230. The reset member 240 is configured to reset the transmission member 230 from the first position 231 to the second position 232 so that the anchor member 220 is parked at the open state 222. The transmission member 230 reaches the first position 231 by ascending, and reaches the second position 232 by descending. The reset member 240 can be a tension spring, a compression spring or other mechanical components with restoring property, which can be determined according to design requirements and is not specifically limited here.

[0085] With reference to Figure 21 In an embodiment, the reset member 240 is a tension spring. One end of the reset member 240 is connected with the upper end of the frame 210, and the other end of the reset member 240 is connected with the transmission member 230. The transmission member 230 can move up and down relative to the frame 210. When the transmission member 230 ascends, the reset member 240 is in a first state. When the transmission member 230 descends, the reset member 240 is in a second state. The length of the tension spring in the first state is less than the length of the tension spring in the second state. The up-down direction in the drawings can be defined as the ascending and descending direction of the transmission member 230.

[0086] In another embodiment, the reset member 240 is a compression spring. The reset member 240 is connected with the lower end of the frame 210, and the other end of the reset member 240 is connected with the transmission member 230. The transmission member 230 can move up and down relative to the frame 210. When the transmission member 230 ascends, the reset member 240 is in a first state. When the transmission member 230 descends, the reset member 240 is in a second state. The length of the compression spring in the first state is greater than the length of the compression spring in the second state.

[0087] With reference to Figure 2 When the locking mechanism 3000 is locked with the locking matching part, the transmission member 230 moves to the first position 231 under the pressure of the locking mechanism 3000. With reference to Figure 8 When the locking mechanism 3000 is unlocked with the locking matching part, the transmission member 230 resets to the second position 232 under the action of the reset member 240.

[0088] With reference to Figure 1 The frame 210 is a housing with a receiving cavity, and the transmission member 230 is slidingly arranged in the receiving cavity. Exemplarily, one end of the reset member 240 is connected with the frame 210, and the other end of the reset member 240 is connected with the transmission member 230.

[0089] With reference to Figure 7 , Figure 19 andFigure 20 The transmission member 230 has a pressing portion 233, and the frame 210 is provided with a guide channel for guiding the pressing portion 233 in the first direction. The pressing portion 233 is in sliding fit with the guide channel. When the locking portion is in locking fit with the locking mechanism 3000, the locking mechanism 3000 pushes the pressing portion 233 in the first direction, so that the transmission member 230 moves to the first position 231. The pressing portion 233 can be circular, rectangular or other shapes, which are not limited herein. For example, refer to Figure 19 and Figure 20 The guide channel can be a guide hole provided on the frame 210, and the upper end of the transmission member 230 is symmetrically provided with two rectangular pressing portions 233. When the locking block 300 is unlocked from the positioning member 200 and moves away from the frame 210, the reset member 240 is in the recovery state and releases the reset energy. The pressing portion 233 passes through the guide channel and out of the frame 210. The transmission member 230 rises and is located at the second position 232. When the locking block 300 is in locking fit with the positioning member 200 and presses the pressing portion 233 until the frame 210 is connected, the reset member 240 stores the reset energy, and the transmission member 230 descends and is located at the first position 231.

[0090] The transmission connection between the anchor claw member 220 and the transmission assembly 260 can be gear meshing, or other transmission modes such as the connecting rod assembly 270, which are not limited herein.

[0091] In an embodiment of the present application, refer to Figure 2 , Figure 8 and Figure 18 The transmission connection between the anchor claw member 220 and the transmission assembly 260 is gear meshing.

The transmission member 230 is fixedly connected or formed with the rack 262, and the gear 261 is in meshing fit with the rack 262.

[0092] In another embodiment of the present application, refer to Figure 2 and Figure 23 The positioning member 200 further comprises a connecting rod assembly 270, which comprises a first rod 271 and a second rod 272 connected in a hinge manner. The first end of the first rod 271, which is not connected to the second rod 272, is hingedly connected to the frame 210. The second end of the second rod 272, which is not connected to the first rod 271, is connected to the transmission member 230. The anchor claw member 220 is connected to the connecting rod assembly 270, and the extension direction of the anchor claw member 220 is the same as the extension direction of the second rod 272. When the reset member 240 is in the recovery state, the transmission member 230 rises, and the connecting rod assembly 270 drives the anchor claw member 220 to slide in the opening direction. When the reset member 240 stores the reset energy, the transmission member 230 descends, and the connecting rod assembly 270 drives the anchor claw member 220 to slide in the retraction direction.

[0093] In another embodiment of the present application, the plurality of anchor members 220 are respectively connected with the transmission member 230, and the plurality of anchor members 220 are arranged in an array around the frame body 210.

The locking block component 300 is selectively locked with the positioning component 200, when the locking block component 300 is locked with the positioning component 200, the transmission assembly 260 drives the anchor member 220 to stop at the retracted state 221, and when the locking block component 300 is unlocked with the positioning component 200, the transmission assembly 260 drives the anchor member 220 to stop at the expanded state 222. The locking and unlocking component of the locking block component 300 can be an electromagnetic locking and unlocking component, or a mechanical transmission locking and unlocking component, or other locking structure components, which are not specifically limited here.

[0097] When the locking block component 300 is unlocked and separated from the positioning component 200, the locking mechanism 3000 can be connected with the cable fixing mechanism 2000, or the locking mechanism 3000 can be separated from the cable fixing mechanism 2000, which are not specifically limited here. Exemplarily, the locking mechanism 3000 comprises a connecting member, the connecting member can be a plate-shaped structure, and the locking mechanism 3000 and the cable fixing mechanism 2000 are both slidingly connected on the connecting member, so that when the locking block component 300 is unlocked and separated from the positioning component 200, the locking mechanism 3000 can be slidingly connected with the cable fixing mechanism 2000 on the connecting member to keep the connection.

[0098] In an embodiment of the present application, the locking and unlocking component of the locking block component 300 is a mechanical transmission locking and unlocking component. The locking block component 300 comprises a locking block shell 310 and a locking portion 320. The locking portion 320 is arranged on the locking block shell 310, and the locking matching portion of the positioning component 200 can be locked and matched with the locking portion 320, so that the locking block shell 310 synchronously drives the transmission assembly 260 when locking the positioning component 200, so that the anchor jaw piece 220 is parked in the retracted state 221.

[0099] Referring to Figure 2 , Figure 11 , Figure 12 The locking matching portion of the positioning component 200 comprises a locking rod 250 arranged on the frame body 210, which is configured to be locked and matched with the locking mechanism 3000. Exemplarily, the locking rod 250 is a pin shaft. In this way, the locking and unlocking of the positioning component 200 to the locking block component 300 can be controlled by unlocking the locking rod 250 from the locking portion 320, so that the anchor jaw piece 220 of the positioning component 200 is in the retracted state 221 when the positioning component 200 is locked to the locking block component 300, and is in the open state 222 when the positioning component 200 is unlocked from the locking block component 300, thereby playing a positioning role of the anchor jaw piece 220 grabbing the hole wall in the deep hole.

[0100] Specifically, referring to Figures 13 to 15 The locking portion 320 comprises a locking piece 321 and a buckle 322 which are pivotally connected to the locking block shell 310, respectively. The locking piece 321 is connected with a first return torsion spring arranged on the locking block shell 310 to receive a torque in a first circumferential direction. When the locking piece 321 is locked to the buckle 322, a locking space for accommodating the locking rod 250 is formed between the locking piece 321 and the locking block shell 310.

[0101] Wherein, referring to Figure 5 , Figures 13 to 15 When the locking block shell 310 is locked and connected to the frame body 210, the locking rod 250 slides against the locking piece 321 and provides a torque for rotating the locking piece 321 in a second circumferential direction opposite to the first circumferential direction, so that the locking rod 250 slides into the locking space. After the locking rod 250 slides into the locking space, the locking piece 321 rotates in the first circumferential direction to be locked with the buckle 322, and the locking block component 300 is in a locked state 324.

[0102] Furthermore, the buckle block 322 is connected to a second return torsion spring provided on the locking block housing 310 so as to be subjected to a torque in the first circumferential direction. The locking block component 300 also includes a rotatably arranged unlocking portion 330, and the unlocking portion 330 includes a lever 331. The lever 331 is configured to provide a torque for the buckle block 322 to rotate along the second circumferential direction so that the buckle block 322 unlocks the locking member 321, and the locking member 321 rotates along the first circumferential direction. The locking rod 250 is unlocked at the locking portion 320, and the locking block component 300 is in an unlocked state 323.

[0103] See Figures 13 to 17 The unlocking portion 330 further includes a pull rod 332. The lever 331 has an L-shaped structure. One end of the lever 331 is connected to the buckle block 322, and the other end of the lever 331 is connected to the pull rod 332. The pull rod 332 pulls the lever 331 to rotate along a first circumferential direction to provide a torque that causes the buckle block 322 to rotate along a second circumferential direction, thereby unlocking the locking member 321 from the buckle block 322 and unlocking the locking rod 250 from the locking portion 320. Exemplarily, the pull rod 332 is a pull rope.

[0104] In another embodiment of the present application, the locking and unlocking component of the locking block component 300 is an electromagnet locking and unlocking component. Figure 21 、 Figure 22 The locking block 300 includes an electromagnetic element 340, which is configured to lock with the positioning member 200 through the electromagnetic force of the electromagnetic element 340. When the electromagnetic element 340 is powered on, a magnetic attraction is generated between the electromagnetic element 340 and the frame 210. The electromagnetic element 340 presses down the pressing portion 233 until the electromagnetic element 340 is attracted to and adheres to the frame 210. When the electromagnetic element 340 is powered off, the electromagnetic element 340 is separated from the frame 210.

[0105] The locking mechanism 3000 also includes a push rod 400, which is connected to the locking block 300 and is used to push the locking block 300, the loading component 100, and the positioning component 200 into the deep hole. The push rod 400 can be composed of multiple rod sections, and the push rod 400 and the locking block 300 can be detachably fixedly connected.

The locking block component 300 is locked with the positioning component 200 to realize the driving of the anchor claw member 220 to the retracted state 221, so as to realize the fixation of the relative position of the push rod component 400 and the locking block component 300 through the positioning component 200, facilitate the application of the pushing force to push the device component 100 to be deployed in the deep hole, and avoid the falling of the push rod component 400. After unlocking, the anchor claw member 220 is opened, and the opened anchor claw member 220 can be tightly clamped with the hole wall of the deep hole by pulling the cable 500, so as to realize the position fixation and simultaneously recover the push rod component 400 and the locking block component 300 from the deep hole.

[0107] Referring to Figures 1 to 12 The application further provides a cable deployment device 1000, which comprises the cable fixing mechanism 2000 and the locking mechanism 3000. The locking block component 300 is detachably arranged separately from the positioning component 200, and the locking block component 300 can be locked and fixed on the positioning component 200 and simultaneously drive the transmission assembly 260 to make the anchor claw member 220 stop at the retracted state 221.

[0108] During the lowering process of the cable deployment device 1000 in the deep hole, the transmission assembly 260 is in transmission connection with the anchor claw member 220, the locking block component 300 is locked with the positioning component 200 to make the transmission member 230 be located at the first position 231, the anchor claw member 220 is in the retracted state 221, the loading component 100 pulls and lowers the cable 500, and the loading component 100 protects and pulls the cable 500 during the lowering process of the cable 500, so as to reduce the damage and winding risk of the cable 500 during the lowering process. When the cable deployment device 1000 pulls the cable 500 to the predetermined position through the loading component 100, the locking block component 300 is unlocked and separated from the positioning component 200 to make the transmission member 230 be located at the second position 232, the anchor claw is in the opened state 222, the anchor claw is clamped into the inner wall of the deep hole to position the loading component 100 to the current predetermined position, and the pulling force of the cable 500 on the positioning component 200 during the straightening of the cable 500 can further increase the depth of the anchor claw member 220 inserted into the inner wall of the deep hole, so as to improve the positioning reliability of the positioning component 200 and realize the effective positioning of the lowering depth of the cable 500 in the deep hole.
