Other movement patterns are of course possible.
In some embodiments of the present invention, a traverse stroke control system is further included, the traverse stroke control mechanism includes a fixed sensor assembly 410 and a moving sensor assembly 420, the fixed sensor assembly 410 is mounted on one of the clamp positioning devices 100 and is located on a moving path of the traverse assembly to form a first stroke switch with the traverse assembly, the moving sensor assembly 420 is mounted on the guide link 200 to be adjustable in mounting position to adjust a distance position with the fixed sensor assembly 410, the traverse assembly is mounted between the fixed sensor assembly 410 and the moving sensor assembly 420, and the moving sensor assembly 420 forms a second stroke switch with the traverse assembly.
In the cable construction project, the total length of the cable is very long, all areas are not required to be processed, and the operation range of the cable 800 is controlled by arranging a transverse moving stroke control system to control the moving interval of the transverse moving assembly.
Specifically, the traverse stroke control mechanism includes a fixed sensor component 410 and a movable sensor component 420, the fixed sensor component 410 is disposed on a clamping and positioning device 100, the movable sensor component 420 is disposed on the guide connecting rod 200, the traverse component is disposed between the fixed sensor component 410 and the movable sensor component 420, when the traverse component moves towards one direction, when the traverse component touches the clamping and positioning device 100, the power device 321 of the traverse component receives a signal, the power device 321 moves in the direction, and in this embodiment, the specific motor is reversed.

In addition, the distance position between the fixed sensor assembly 410 and the movable sensor assembly 420 can be adjusted by controlling the position of the movable sensor assembly 200 on the guide link 200, thereby controlling the working range of the cable 800. The distance between the two is long, so that the cable polishing operation range is large; the distance between the two is short, the cable grinding operation range is small, and therefore the control of the cable operation range is completed.
In some embodiments of the present invention, the guiding mechanism 120 includes two first guiding rods, the two first guiding rods are parallel and fixedly disposed on the fixed supporting plate 110, one end of one clamping block 130 is hinged or detachably connected to one first guiding rod, the other end is detachably connected to the other first guiding rod, and both ends of the other clamping block are slidably connected to the two first guiding rods, respectively, and can slide along the first guiding rods.
As shown in fig. 5 and 6, in this embodiment, two clamping blocks 130 are respectively disposed opposite to each other in the vertical direction, two ends of the clamping block 130 disposed at the upper portion are respectively slidably connected to two first guide rods, one end of the clamping block 130 disposed at the lower portion is hinged or detachably connected to one first guide rod, and the other end is detachably connected to the other first guide rod.
When the cable 800 is clamped, the cable 800 is disassembled from the first guide rod when two ends of the clamping block 130 arranged at the lower part are detachably connected with the first guide rod, and the clamping block 130 is connected with the first guide rod after the cable is placed.
When the detachable mode that one end is hinged and the other end is detachable is adopted, only one end and the first guide rod need to be detached, and the specific reference is 5. And then rotate about the hinged end, which is much simpler and avoids the problem of easy loss of the clamping block 130 when it is removed.
After the cable 800 is loaded into the cable positioning clamp cavity 140, the adjustment mechanism adjusts the position of at least one clamp block 130 to move along the first guide bar toward the other clamp block 130 to clamp the cable 800 in the cavity. Specifically, the following modes can be adopted:
1. the upper holding block 130 is controlled to slide closer along the first guide bar toward the lower holding block 130. 2. The first guide rod is controlled to lift, the position of the clamping block 130 at the upper part is fixed, and the first guide rod drives the clamping block 130 at the lower part to move upwards in the lifting process to be close to the clamping block 130 at the upper part. 3. Meanwhile, by adopting the above two modes, the two clamping blocks 130 move towards each other.
In some embodiments of the present invention, the two clamping blocks 130 are V-shaped plates having V-shaped grooves, the two inner side wall surfaces of the V-shaped grooves are provided with the pressing blocks 600, all the pressing blocks 600 together enclose the cable positioning clamping cavity 140, and the pressing blocks 600 are provided with corrugated contour grooves 610 matching with the corrugated pipe sheath of the cable.
In this embodiment, two grip blocks 130 are the V-shaped board that has the V-shaped groove, and when packing cable 800 into cable location centre gripping chamber 140, because the slot in V-shaped groove can accomplish the positioning action to cable 800 automatically for cable 800 gets into cable location centre gripping chamber 140's axle center department automatically, and the installation location is convenient and fast more.
The pressing blocks 600 are four, two inner side wall surfaces of each clamping block 130 are respectively provided with one pressing block, the pressing blocks and the clamping blocks jointly form a cable positioning clamping cavity 140 in a surrounding mode, the pressing blocks 600 are made of materials with certain hardness and elasticity, the cable 800 can be stably clamped, and meanwhile, the soft materials cannot generate stress deformation on the cable 800.
In addition, when the cable 800 leaves a factory, the corrugated pipe sheath is arranged on the outer surface of the cable 800 to protect the outer surface of the cable 800, and the corrugated pipe sheath needs to be stripped during construction operation, but the cable 800 is long, and all the corrugated pipe sheaths do not need to be stripped during construction operation, and only a part of the corrugated pipe sheaths needs to be stripped. However, the portion still needs to be clamped during construction operation, and if the clamping surface of the pressing block 600 is smooth, the cable 800 coated with the corrugated pipe sheath cannot be clamped, and the portion easily slides in the cable positioning and clamping cavity 140, so that the clamping significance is lost.

When carrying out construction work to cable 800, the position of cable 800 has been confirmed, can't adjust the position of cable 800 again and adjust, has certain defect when cable 800 itself, if cable 800 local area has certain bending, can appear the unable circumstances of contradicting at cable 800 outer wall of partial compact heap 600, leads to the unstable condition of centre gripping. When the situation occurs, by adjusting the fine adjustment mechanism 700, the pressing blocks 600 which do not abut against the outer wall of the cable 800 move in the radial direction of the cable positioning and clamping cavity 140 until the pressing blocks abut against the outer wall of the cable 800, so that all the pressing blocks 600 abut against the outer wall of the cable 800, and the clamping effect is ensured.
Specifically, as shown in fig. 4 and 6, when the pressing block 600 is finely adjusted, by rotating the adjusting screw 710, when the adjusting screw 710 is screwed in, the adjusting screw 710 pushes the pressing block 600 to move in the radial direction of the cable positioning and clamping cavity 140 until the pressing block 600 abuts against the outer wall surface of the cable 800. When the pressing block 600 moves, the spring guide rod 720 connected with the pressing block moves synchronously with the pressing block, and the spring 730 sleeved on the spring guide rod 720 can enable the pressing plate 600 to cling to the cable 800.
