The first mounting plate 711 comprises a first plate body and a second plate body which are clamped to each other along the length direction of the frame body 10, the first plate body is arranged close to the second clamping part 72, the second plate body is provided with a first through hole and a second through hole which are in step communication, the first through hole is arranged close to the first plate body, the diameter of the first through hole is larger than the diameter of the second through hole, the bottom of the adjusting member 80 is provided with a circular stop portion, the diameter of the stop portion is larger than the diameter of the main body portion of the adjusting member 80, the stop portion is arranged in the first through hole, and the step surface formed between the first through hole and the second through hole is in stop cooperation with the stop portion, so that the adjusting member 80 is rotationally connected with the first mounting plate 711. In this way, the adjusting member 80 can be conveniently connected with the frame body and the first mounting plate 711.

[0067] Further, the frame body 10 comprises a matching rod 1001, the length direction of the matching rod 1001 is the same as the length direction of the frame body 10 as a whole, the matching rod 1001 is provided with a plurality of matching threaded holes which are spaced apart along the length direction of the matching rod 1001, and the cable spraying mechanism further comprises a locking bolt, after the position of the first mounting plate 711 is adjusted by the adjusting member 80, the first mounting plate 711 and the matching threaded holes can be connected by the locking bolt. In this way, the convenience of connecting the first mounting plate 711 with the frame body 10 can be ensured.

[0068] Further, the second mold 22 further comprises a first buffer part 223 which is arranged between the second body part 221 and the second connecting part 222, so that the second body part 221 moves relative to the second connecting part 222 along the length direction of the frame body 10, and the cable spraying mechanism comprises a second buffer part 90 which is arranged between the second clamping part 72 and the second mold 22, so that the second clamping part 72 and the second mold 22 move relative to the length direction of the frame body 10. In the present scheme, the first buffer part 223 comprises a plurality of springs which are telescopic along the length direction of the frame body 10, and the second buffer part 90 comprises a plurality of springs which are telescopic along the length direction of the frame body 10. Due to the different diameters of the cables, the situation that the nozzle assembly 20 is not in the buckling state when the clamping assembly clamps the cable, or the situation that the clamping assembly fails to clamp the cable when the nozzle assembly 20 is in the buckling state, can occur. The arrangement of the first buffer part 223 and the second buffer part 90 can make the nozzle assembly 20 be in the buckling state when the clamping assembly first clamps the cable, and can also make the clamping assembly be able to clamp the cable when the nozzle assembly 20 is first in the buckling state, so that the smoothness of the cable spraying process can be ensured.

[0069] As Figure 3As shown, the first mold 21 is fixedly arranged on the frame body 10, and the second mold 22 is movably arranged on the frame body 10. The driving part 30 comprises a third driving member 31 and a lead screw 32. The third driving member 31 is arranged on the first connecting part 212 of the first mold 21, and is a third driving motor. The lead screw 32 is rotatably arranged on the first connecting part 212 of the first mold 21, and the second mold 22 is threadedly connected with the lead screw 32. The third driving motor and the lead screw 32 have simple structure and good driving stability.

[0070] Further, the frame body 10 comprises a fixed frame 11 and a sliding frame 12. The fixed frame 11 is used for being assembled to an additional cable running device, and the sliding frame 12 is movably arranged on the fixed frame 11.

The length direction of the sliding frame 12 is the same as the direction from the first limit position to the second limit position. The nozzle assembly 20 and the driving part 30 are arranged on the sliding frame 12. The first mold 21 is fixedly connected on the sliding frame 12, and the second mold 22 is movably arranged on the sliding frame 12. Meanwhile, the first mold 21 drives the first adjusting part 41 to move synchronously, and the second mold 22 drives the second adjusting part 42 to move synchronously. The distribution direction of the first mold 21 and the second mold 22 is the same as the direction from the first limit position to the second limit position. The second mold 22 has an abutting state and a moving state arranged relative to the fixed frame 11. When the second mold 22 is in the moving state, the second mold 22 is close to or away from the first mold 21. When the second mold 22 is in the abutting state, the sliding frame 12 can move between the first limit position and the second limit position. When the sliding frame 12 is in the second limit position, the second mold 22 can switch between the abutting state and the moving state.

[0071] Before the cable is sprayed, the sliding frame 12 is ensured to be in the second limit position, and the second mold 22 is in the abutting state. Then, the third driving motor drives the screw rod 32 to rotate. Under the action of the screw rod 32 and the second mold 22, the sliding frame 12 moves from the second limit position to the first limit position. The movement of the sliding frame 12 drives the first mold 21 to move. The first mold 21 and the second mold 22 have the maximum spacing. Since the cable may be inclined to a certain extent when it is in the air, that is, the extension direction of the cable is not perpendicular to the sliding direction of the sliding frame 12, the above-mentioned maximum spacing can ensure that the cable is smoothly arranged between the first mold 21 and the second mold 22. After the cable is arranged between the first mold 21 and the second mold 22, the sliding frame 12 is moved from the first limit position to the second limit position, and the first mold 21 is close to the cable until the first adjusting part 41 abuts against the cable. Then, the third driving motor drives the screw rod 32 to rotate, so that the second mold 22 drives the second adjusting part 42 to be close to the cable until the second adjusting part 42 abuts against the first adjusting part 41, the second mold 22 and the first mold 21 are mutually buckled, and the second clamping roller 722 abuts against the cable. After the device is installed on the cable running device, the miniaturization of the device in the sliding direction of the sliding frame 12 can be ensured under the premise of smoothly clamping the cable, the overall gravity center is reduced, the overall device weight is reduced, the stability and smoothness of the cable spraying device on the cable running device are ensured.

[0072] As Figure 5 and Figure 7As shown, the fixing frame 11 comprises an assembling part 111, an extension rod 112 and a limiting part 113. The assembling part 111 is used for assembling on the cable walking device, and the sliding frame 12 is slidably arranged on the assembling part 111.

The limiting part 113 is arranged at the end of the extension rod 112 away from the assembling part 111, and is located at the end of the second mold 22 away from the first mold 21. The limiting part 113 is used for abutting with the second mold 22 to make the second mold 22 in the abutting state. The assembling part 111 is provided with a guide hole, the sliding frame 12 comprises a sliding part 121, a mounting part 122 and a connecting part 123 connected in sequence along the sliding direction of the sliding frame 12, and the sliding part 121 is movably arranged in the guide hole; the first mold 21 is arranged on the mounting part 122, one end of the lead screw 32 is rotatably arranged on the mounting part 122, and the other end of the lead screw 32 extends towards the connecting part 123; the second mold 22 is slidably arranged on the connecting part 123; when the sliding frame 12 is in the second limit position and the second mold 22 is in the abutting state, there is a spacing between the end of the lead screw 32 away from the mounting part 122 and the second mold 22. In this way, the structure is simple, the layout is compact, and the smoothness of switching of the sliding frame 12 between the first limit position and the second limit position can be ensured.

[0073] Specifically, the sliding part 121 comprises a sliding rod 1211 and a first stop part 1212, one end of the sliding rod 1211 is connected with the mounting part 122, the other end of the sliding rod 1211 passes through the guide hole and is connected with the first stop part 1212, and the first stop part 1212 is in stop cooperation with the assembling part 111 of the fixing frame 11.
