DETAILED DESCRIPTION

[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present invention, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined and referenced with each other without contradiction.

[0036] The first embodiment of the present invention relates to a manhole optical cable construction mechanical arm, such as Figure 1 As shown, it includes: a main rod 1, a fixed clamping jaw 2, a movable clamping jaw 3, a handle 4 and a linkage assembly 5. Among them, the fixed clamping jaw 2 and the movable clamping jaw 3 are arranged opposite to each other and are both connected to the main rod 1, and the movable clamping jaw 3 is used to clamp objects together with the fixed clamping jaw 2. The handle 4 is arranged on the side of the main rod 1 away from the fixed clamping jaw 2 and the movable clamping jaw 3. The staff holds the handle 4, and the handle 4 drives the movable clamping jaw 3 and the fixed clamping jaw 2 to move closer to or away from each other through the linkage assembly 5. In addition, the main rod 1 can be set as a hollow tube body, and the linkage assembly 5 is arranged in the tube body.

[0037] It is not difficult to find from the above content that, since the fixed jaw 2 and the movable jaw 3 in the manhole optical cable construction mechanical arm are arranged relatively and are both connected to the main rod 1, and the handle 4 is arranged on the side of the main rod 1 away from the fixed jaw 2 and the movable jaw 3, and is connected to the movable jaw 3 through the linkage component 5, the staff can drive the linkage component 5 to move by holding the handle 4, and then drive the movable jaw 3 and the fixed jaw 2 to move closer to or away from each other, so that the movable jaw 3 can clamp the object together with the fixed jaw 2. Therefore, when it is necessary to operate the optical cable underground, the staff can extend the main rod 1 into the manhole, and by operating the handle 4, the handle 4 drives the movable jaw 3 to move closer to or away from the side of the fixed jaw 2 to realize the operation of the cable. Therefore, the optical cable can be simply constructed without going down the well, eliminating the trouble of using a ladder when going down the well, reducing the difficulty of operation for the staff, and avoiding threats to the personal safety of the staff.

[0038] In addition, in this embodiment, if Figure 1As shown, the manhole optical cable construction mechanical arm may also include a lighting assembly 6 detachably arranged on the main pole 1, so that when the staff extends the main pole 1 into the well to work, lighting is provided to achieve precise work. Specifically, the lighting assembly 6 includes: a support member 61 detachably connected to the main pole 1, and a lighting lamp 62 arranged on the support member 61. For example, a positioning groove may be provided on the main pole 1, and a positioning protrusion may be provided on the support member 61. Through the cooperation between the positioning protrusion and the positioning groove, the detachable connection between the support member 61 and the main pole 1 is achieved.

[0039] In addition, the illuminating lamp 62 can also be detachably connected to the supporting member 61. For example, a groove can be provided on the supporting member 61 in a direction parallel to the main rod 1, and a first buckle and a second buckle are respectively provided on both sides of the groove. When the illuminating lamp 62 needs to be installed, the illuminating lamp 62 can be placed in the groove, and the first buckle and the second buckle are mutually engaged to fix the illuminating lamp 62 in the groove. Furthermore, a power supply can also be provided on the main rod 1, and a contact electrically connected to the power supply can be provided at the bottom of the groove, and the contact can be electrically connected to the illuminating lamp 62, thereby realizing the electrical connection between the power supply and the illuminating lamp 62, and the illuminating lamp 62 is directly powered by the power supply.

[0040] It should be noted that, in this embodiment, Figure 1 As shown, the fixed clamping jaw 2 includes: a first clamping portion 21 connected to the main rod 1 and a first cutting edge portion 22 connected to the first clamping portion 21, and the movable clamping jaw 3 includes: a second clamping portion 31 connected to the main rod 1 and a second cutting edge portion 32 connected to the second clamping portion 31. The first clamping portion 21 and the second clamping portion 31 are arranged opposite to each other and are used to clamp the optical cable together, and the first cutting edge portion 22 and the second cutting edge portion 32 are arranged opposite to each other and are used to cut off the fixed binding wire. Thus, operations such as cutting off the fixed binding wire and clamping the optical cable can be realized.

[0041] In addition, it is worth noting that in this embodiment, if Figure 1As shown, the linkage assembly 5 may specifically include: a connecting shaft 51, a pull block 52, an elastic component 53 and a connecting line 54, wherein the fixed clamping jaw 2 and the movable clamping jaw 3 may be connected through the connecting shaft 51, the pull block 52 is arranged on the connecting shaft 51, and the elastic component 53 is arranged on the pull block 52 along the length direction of the main rod 1, and the connecting line 54 passes through the elastic component 53 to connect the pull block 52 with the handle 4. That is, when the staff operates the handle 4, the pull block 52 is driven to move toward the side of the handle 4, and the elastic component 53 is compressed, so that the fixed clamping jaw 2 and the movable clamping jaw 3 are close to each other, and the object is clamped between the fixed clamping jaw 2 and the movable clamping jaw 3, and when the staff releases the handle 4, the elastic component 53 rebounds, and the pull block 52 rebounds to the side away from the handle 4, so that the fixed clamping jaw 2 and the movable clamping jaw 3 are away from each other. In actual use, the elastic component 53 can be a spring, and the connecting line 54 can be a steel wire rope.

[0042] The second embodiment of the present invention relates to a manhole optical cable construction mechanical arm. The second embodiment is a further improvement on the basis of the first embodiment, and the main improvement is that: in this embodiment, the manhole optical cable construction mechanical arm may also include: a main control module, a detection module and a reminder module electrically connected to the main control module respectively. Among them, the detection module is arranged on the side of the fixed jaw facing the movable jaw, and is used to detect the distance between the fixed jaw and the object to be clamped. The reminder module can be arranged at any position of the main rod, and correspondingly, a component to be measured can be arranged on the movable jaw. When the detection module detects that the distance between the movable jaw and the fixed jaw reaches the preset distance, the main control module turns on the reminder module to remind the staff that the fixed jaw and the movable jaw have been clamped in place.

[0043] Specifically, the detection module can be a non-contact proximity sensor. Since the non-contact proximity sensor realizes the opening and closing of the driving device by detecting the size of the magnetic field, the component to be tested must be made of metal. When the movable clamp moves, it drives the component to be tested to move. The movement of the component to be tested changes the size of the magnetic field around the non-contact proximity sensor. Once the magnetic field measured by the sensor fluctuates in a large range, it indicates that the object to be clamped is located between the fixed clamp and the movable clamp. At this time, the main control module turns on the reminder module. In addition, the reminder module can be any one of an acoustic alarm, a light alarm, and an audible and visual alarm.

[0044] In actual use, the detection module can also be a photoelectric sensor, an infrared distance sensor, etc., as long as it can detect the distance between the fixed clamping claw and the object to be clamped.

[0045] The third embodiment of the present invention relates to a manhole optical cable construction mechanical arm. The third embodiment is a further improvement on the first embodiment, and the main improvements are: Figure 2As shown, in this embodiment, the manhole optical cable construction mechanical arm may also include: a fixing member 7 arranged on the main rod 1, when the movable jaw 3 moves toward the side of the fixed jaw 2 to a preset position, the movable jaw and the fixed jaw are fixed at the preset position of the main rod 1 through the fixing member 7.

[0046] Specifically, the fixing member 7 may include: a protrusion 71 slidably arranged on the tube wall, an operating rod 72 connected to the protrusion 71, and a spring 73 connecting the protrusion 71 and the main rod 1. The operating rod 72 may partially protrude from the main rod 1. When the connecting line 54 pulls the pull block 52 toward the handle 4, the protrusion 71 is driven to move toward the tube wall of the main rod 1 and compress the spring 73. After the pull block 52 moves to a certain position, the protrusion 71 moves away from the tube wall under the action of the rebound force of the spring 73. The pull block 52 moves on one side of the wall, and the pull block 52 is limited at a preset height in the tube body to prevent the elastic component 53 from rebounding, and prevent the part to be clamped from escaping from the fixed clamping jaw 2 and the movable clamping jaw 3; when the part to be clamped needs to be disengaged, the operating rod 72 can be pulled to drive the protrusion 71 to move toward the side of the tube wall of the main rod 1, and the spring 73 is compressed, and the protrusion 71 stops supporting the pull block 52, so that the elastic component 53 rebounds, and drives the fixed clamping jaw 2 and the movable clamping jaw 3 to return to their initial positions.

[0047] Those skilled in the art will appreciate that the above-mentioned embodiments are specific embodiments for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
