The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0031] Example 1

[0032] Reference Figure 1-2 , which is the first embodiment of the present invention, provides a cable laying auxiliary device, including a guide rail 100, a wire wheel 200 is fixedly installed on the side of the guide rail 100 near the end, a wheel 301 is movably arranged on the guide rail 100, a connecting rod 302 is installed on the side of the wheel 301, a traction plate 300 is fixedly arranged on the bottom surface of the connecting rod 302, a lead 201 is connected between the traction plate 300 and the wire wheel 200, a fixed gripper 400 is arranged on the bottom surface of the traction plate 300, and the fixed gripper 400 can clamp the cable terminal; by controlling the rotation of the wire wheel 200, the traction plate 300 can be driven to move in the extension direction of the guide rail 100, thereby driving the cable terminal to move in the same direction.

[0033] A fixed beam 101 is fixedly arranged on the top of the guide rail 100 , and three welding beams 102 are fixedly arranged on the side of the fixed beam 101 . The device can be welded to an existing cable steel frame or implanted on the side wall of a cable trench through the welding beams 102 .

[0034] A traction hook 303 is fixedly connected to the side of the traction plate 300 , one end of the lead wire 201 is fixedly connected to the traction hook 303 , and the end of the lead wire 201 can be tied into a knot and sleeved on the traction hook 303 .

[0035] The traction hook 303, the wire wheel 200 and the lead wire 201 are each provided with two wire wheels 200, and the two wire wheels 200 are respectively fixedly mounted at the two ends of the same side of the guide rail 100, and the two traction hooks 303 are symmetrically arranged at the front and rear ends of the traction plate 300 (front and rear refer to the forward and backward directions of the traction plate 300). The traction plate 300 can be controlled to move forward and backward at the front and rear ends of the guide rail 100 through the wire wheels 200 and the lead wire 201 at the corresponding positions, thereby controlling the cable terminal to move forward or backward.

[0036] The guide rail 100 includes a connecting rail 103 fixedly connected to the lower side of the fixed beam 101, and a movable rail 104 fixedly connected to the bottom surface of the connecting rail 103. A sliding groove 105 is provided on the movable rail 104 on one side close to the connecting rail 103. The wheel 301 is movably connected in the sliding groove 105, so that the wire wheel 200 controls the traction plate 300 to move on the movable rail 104. The bottom width of the wheel 301 is the same as the groove width, so as to limit the movable path of the wheel 301 and prevent the traction plate 300 and the fixed gripper 400 from shaking left and right as a whole.

[0037] The slide grooves 105 are provided with two and are symmetrically distributed on the left and right sides of the movable track 104. Two sets of wheels 301 and connecting rods 302 are provided on the left and right sides of the movable track 104 to enhance the stability of the traction plate 300 on the guide rail 100. The connecting rods 302 are in a horizontal L-shape, and the upper ends of the connecting rods 302 on the left and right sides are arranged opposite to each other.

[0038] In summary, when using this device, the cable terminal is clamped and fixed using the fixed gripper 400, and then the wire wheel 200 at the end is controlled to rotate to pull the traction plate 300 toward the end through the lead wire 201, so that the cable terminal can be driven to move forward synchronously to achieve the purpose of laying the cable.

[0039] This device is installed in the cable trench during the construction period, so that it can be directly used in the later transformation, expansion and other work. In addition, the installation frame of this device can be set with multiple groups of fixed grippers 400 to meet the needs of laying cables in the later stage. When laying cables in the later stage, there is no need to open all the covers of the cable trench one by one and re-carry out manual handling and laying. This device is mainly used for secondary cable laying. In the conventional new cable laying method, it takes about 2 minutes and no less than 2 people to work at the same time for each 5-10m cable laying. Using the device in this project, the fastest 10m cable laying time can be reduced to 30s, and only 2 or even 1 person is needed to complete the cable laying work.

[0040] Example 2

[0041] Reference Figure 3 to Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the fixed gripper 400 includes four connecting frames 401 fixedly connected to the traction plate 300 and symmetrically distributed in pairs, a fixed steel frame 402 fixedly arranged on the bottom surface of the connecting frame 401, and a spring 403 arranged on the side of the fixed steel frame 402, and a clamping member 404 fixedly arranged at the other end of the spring 403.

[0042] The fixed steel frame 402, spring 403 and clamping member 404 are all provided with two symmetrical groups. The fixed steel frame 402 is C-shaped. The openings of the two fixed steel frames 402 are arranged opposite to each other. The openings of the two clamping members 404 are also arranged opposite to each other. The springs 403 located between the clamping members 404 and the fixed steel frame 402 are each provided with four springs evenly distributed side by side. The springs 403 on the left and right sides of the two clamping members 404 are symmetrically distributed. The two clamping members 404 clamp the cable terminal by the pressure of the springs 403.

[0043] The opposite sides of the two clamping members 404 include a plurality of convex teeth 405 arranged side by side, and the opposite sides of the convex teeth 405 on the left and right sides are C-shaped. The convex teeth 405 on both sides are arranged opposite to each other and fit with the outer surface of the cable terminal, thereby increasing the contact area with the surface of the cable terminal and facilitating the clamping of the cable terminal.

[0044] The two rows of convex teeth 405 are arranged in an alternating manner, and the elasticity of the spring 403 reserves clamping space for cable terminals of different widths. The staggered arrangement of the left and right rows of convex teeth 405, on the one hand, increases the clamping range of the clamping member 404 on the length direction of the cable terminal, thereby facilitating better clamping of the cable terminal. On the other hand, it reserves operable space for cable terminals with a smaller radius, thereby increasing the radius range of the cable terminals that can be clamped by the fixed gripper 400.

[0045] A control member 406 is fixedly provided on the clamping member 404, and the control member 406 includes a control rod 407 connected to the clamping member 404, and a control panel 408 fixedly connected to the control rod 407. The end of the control rod 407 away from the clamping member 404 is in the same direction as the opening of the clamping member 404, and the control panel 408 is located at the end of the control rod 407 away from the clamping member 404. For the clamping member 404 located on the left side, the control panel 408 for controlling the clamping member 404 is located outside the fixed steel frame 402 on the right side, and a space for the control panel 408 to move is reserved between the control panel 408 and the fixed steel frame 402. The same applies to the control panel 408 corresponding to the clamping member 404 on the right side.

[0046] In summary, by bringing the two control panels 408 closer to each other, the two clamping members 404 can be pulled apart, and the springs 403 respectively connected to the two clamping members 404 can be squeezed to loosen the cable terminal. The staff can then remove the cable terminal, loosen the two control panels 408, and the springs 403 on both sides rebound to return the two clamping members 404 to the clamped state; when the cable terminal needs to be fixed, press the two control panels 408 closer to each other, then place the cable terminal between the two clamping members 404, and then loosen the control panels 408.

[0047] The remaining structures are the same as those of Example 1.

[0048] Example 3

[0049] Reference Figure 1-2 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the guide rails 100 and the fixed beams 101 are provided with multiple groups, and the connecting rails 103 are respectively provided with blocks 106 and slots 107 at both ends. The blocks 106 and slots 107 fit together, and the multiple guide rails 100 can be connected together end to end in sequence. The length of each group of guide rails 100 is the same as the length of the fixed beam 101. The connecting rails 103 and the movable rails 104 can also be connected in a straight line. The mortise and tenon structure of the guide rails 100 facilitates accurate connection of the rails, and at the same time facilitates shortening the rails to meet the needs of cable trenches of different lengths, thereby increasing the applicability and flexibility of the rails for cable trenches of different lengths.

[0050] For a longer cable trench, place multiple sections of guide rails 100, open the cable covers at the connection of adjacent guide rails 100 to facilitate the operation of the wire wheel 200, and when the traction plate 300 and the cable terminal are pulled between the two sections of guide rails 100, remove the two lead wires 201 on the front guide rail 100 on the traction plate 300, install the ends of the two lead wires 201 on the rear section of the guide rail 100, and then go to the end of the rear end guide rail 100 to control the wire wheel 200 there to pull the traction plate 300 and the cable terminal.

[0051] The remaining structure is the same as that of Example 2.
