DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model is described clearly and completely, obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model. Embodiment one

[0028] In order to solve the technical problems in the background art, a cable traction equipment in a cable trench is given as follows:

[0029] Combining Figures 1-4 The utility model provides a cable traction equipment in a cable trench, including frame body 1, the top of frame body 1 is installed with a plurality of moving wheels 11, the top of frame body 1 is fixedly installed with base 2, the top of base 2 is fixedly installed with two vertical standing boards 3, two standing boards 3 are all rotationally installed with horizontal pivot shafts 31, two pivot shafts 31 are all fixedly installed with turntable 32 on the side close to each other, two turntables 32 are all installed with fixed column 33 on the side close to each other, and the central axis of fixed column 33 and the central axis of pivot shaft 31 are located on the same axial direction.

[0030] Two The side close to each other of turntable 32 is all along fixed column 33 direction and is set with sliding slot 321, two sliding slots 321 are all slidably installed with the pressing plate 4 that can be contacted with fixed column 33, one of the turntable 32 is installed with the drive piece 5 that is connected with the pressing plate 4, and it is used to make the pressing plate 4 slide or stop sliding in two sliding slots 321.

[0031] The base 2 on and located at the side, away from two turntables 32, of one of the standing boards 3 is fixedly installed with fixed seat 21, horizontal rotating lever 22 is rotationally installed on fixed seat 21, and servo motor 23 for driving rotating lever 22 to rotate is fixedly installed on fixed seat 21, adjusting mechanism 6 is installed on the base 2 between fixed seat 21 and standing board 3, transmission mechanism 7 is installed on adjusting mechanism 6, adjusting mechanism 6 is used to rotate transmission mechanism 7, so that the two ends of transmission mechanism 7 are connected with one of the pivot shafts 31 and rotating lever 22 respectively, to form transmission connection between rotating lever 22 and pivot shaft 31 through transmission mechanism 7, and the equipment is powered by external power supply.

[0032] When laying cables, when transporting the cable reel to the entrance of the cable trench, this device is moved to one side of the cable reel. The cable end wound on the cable reel is inserted into the side opposite the pressure plate 4 and the fixing post 33. The driving component 5 causes the pressure plate 4 to slide in the two sliding grooves 321, so that the pressure plate 4 abuts against the cable end, thereby achieving the effect of fixing the cable end through the pressure plate 4 and the fixing post 33. Then, the adjustment mechanism 6 rotates the transmission mechanism 7, so that the two ends of the transmission mechanism 7 are connected to the rotating shaft 31 and the rotating rod 22 respectively. At this time, the servo motor 23 is controlled to work, driving the rotating rod 22 to rotate on the fixed seat 21, thereby driving the rotating shaft 31 to rotate through the transmission mechanism 7, so that the two turntables 32 rotate around the two rotating shafts 31 respectively, thereby winding the cable through the fixing post 33 and the pressure plate 4. When the outermost layer of the cable wound outside the fixing post 33 and the pressure plate 4 is flush with the outer periphery of the turntable 32, the servo motor is controlled to work. 23 is closed, and then the transmission mechanism 7 is rotated by the adjustment mechanism 6 so that the two ends of the transmission mechanism 7 are not connected to the rotating shaft 31 and the rotating rod 22. At this time, the frame 1 is pulled to move along the cable trench, and the two turntables 32 rotate in opposite directions around the two rotating shafts 31 respectively. This allows the cable wrapped around the fixed column 33 and the pressure plate 4 to be unfolded and laid in the cable trench, achieving the effect of power traction. After the cable wrapped around the fixed column 33 and the pressure plate 4 is fully unfolded, the transmission mechanism 7 is rotated by the adjustment mechanism 6 so that the two ends of the transmission mechanism 7 are connected to the rotating shaft 31 and the rotating rod 22 respectively, controlling the servo motor 23 to work and wind the cable. This process is repeated to complete the power laying effect. This method replaces the method of workers pulling the cable end along the cable trench to make the cable reel with the cable wrapped around it rotate to unfold the cable, saving workers' physical strength, improving traction efficiency, and thus improving cable laying efficiency. Example 2

[0033] like Figures 1-4 As shown, based on the above embodiments, this embodiment further provides the following:

[0034] In this embodiment, the driving component 5 includes a driving rod 51 rotatably mounted on the turntable 32. The axial direction of the driving rod 51 is perpendicular to the axial direction of the rotating shaft 31. One end of the driving rod 51 extends into the slide groove 321 and is threadedly connected to the pressure plate 4. In use, a force is applied to the driving rod 51 to make it rotate on the turntable 32, which causes the pressure plate 4 to move spirally along the driving rod 51, thereby allowing the pressure plate 4 to slide within the two slide grooves 321. Since the threaded connection between the driving rod 51 and the pressure plate 4 has a self-locking property, the position of the pressure plate 4 can be fixed without rotating the driving rod 51, making the operation simple.

[0035] In this embodiment, the adjustment mechanism 6 includes a mounting bracket 61 fixedly mounted on the base 2. A vertical rotating rod 62 is rotatably mounted on the mounting bracket 61. A transmission mechanism 7 is mounted on the top of the rotating rod 62. An adjustment member 63 acting on the rotating rod 62 is mounted on the mounting bracket 61. This adjustment member is used to make the rotating rod 62 rotate or stop rotating on the mounting bracket 61. In use, the rotating rod 62 is rotated on the mounting bracket 61 by the adjustment member 63, thereby driving the transmission mechanism 7 to rotate around the rotating rod 62.

[0036] In this embodiment, the adjusting member 63 includes a worm gear 631 coaxially fixed to the rotating rod 62. A worm 632 meshing with the worm gear 631 is rotatably mounted on the mounting frame 61. In use, a force is applied to the worm 632 to make it rotate on the mounting frame 61, thereby driving the rotating rod 62 to rotate on the mounting frame 61 through the worm gear 631. The operation is simple. Since the meshing of the worm gear 631 and the worm 632 has a self-locking property, the position of the rotating rod 62 can be fixed when the worm 632 is not rotated, which is convenient for use. Example 3

[0037] like Figures 1-4 As shown, based on the above embodiments, this embodiment further provides the following:

The rotating rod 22 and the rotating shaft 31 are respectively provided with locking slots 74 on their respective sides. The two locking blocks 73 can extend into the two locking slots 74 and engage with the rotating rod 22 and the rotating shaft 31 respectively. In use, when the rotating rod 62 rotates on the mounting frame 61, the fixed frame 71 can drive the rotating shaft 72 to rotate around the rotating rod 62. When the two locking blocks 73 can extend into the two locking slots 74 respectively, the two locking blocks 73 engage with the rotating rod 22 and the rotating shaft 31 respectively. At this time, when the rotating rod 22 rotates on the fixed seat 21, the rotating shaft 31 can be driven to rotate through the rotating shaft 72, realizing the transmission connection effect between the rotating rod 22 and the rotating shaft 31 through the transmission mechanism 7.

[0039] In this embodiment, a stabilizing mechanism 8 that can contact the ground is installed on the frame 1. By setting the stabilizing mechanism 8, when the frame 1 is fixed in position, the servo motor 23 is controlled to work and drive the two turntables 32 to rotate and wind the cable, so that the stabilizing mechanism 8 contacts the ground, which increases the stability of the equipment during operation and is beneficial to the cable pulling operation.

[0040] In the embodiment, the stabilizing mechanism 8 comprises a guide column 81 movably penetrating the frame 1 in the vertical direction, the bottom of the guide column 81 is fixed with a connecting plate 82, the bottom of the connecting plate 82 is linearly fixed with a plurality of tapered columns 83 in the horizontal direction, the frame 1 is threaded with a threaded column 84 in the vertical direction, the bottom end of the threaded column 84 is rotationally connected with the connecting plate 82, in use, a rotating force is applied to the threaded column 84 to make it screw down on the frame 1, at this time, the threaded column 84 and the connecting plate 82 are rotated, so that the connecting plate 82 is displaced downward along the guide column 81, and the plurality of tapered columns 83 are displaced downward and inserted into the ground, the positioning effect of the frame 1 is realized, and the displacement of the frame 1 during traction of the cable is effectively avoided, so that the stability of the device during work is increased.
