DETAILED DESCRIPTION

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] Embodiment 1: A surface grinding device for high voltage cable rubber, such as Figure 1-Figure 6 As shown, it includes a support frame 1, a sliding frame 11 is slidably connected between the left and right sides of the support frame 1, a first screw rod 12 is rotatably connected to the left side of the support frame 1, the first screw rod 12 is threadedly connected to the sliding frame 11, an opening and closing member 13 symmetrically distributed on the left and right is slidably connected to the support frame 1, a symmetrically distributed latch assembly is provided on the support frame 1, an electric slide rail 16 symmetrically distributed front and back is installed on the support frame 1, a sliding member 17 is rotatably connected between the two electric slide rails 16, and a second screw rod 18 is rotatably connected to the sliding member 17, An adjusting frame 19 is threadedly connected to the second screw rod 18, and the adjusting frame 19 is slidably connected to the sliding member 17. Symmetrically distributed clamping members 111 are slidably connected to the adjusting frame 19, and the two clamping members 111 are also slidably connected to the sliding member 17. A storage spring 110 is connected between the two clamping members 111 and the adjusting frame 19, and an electric push rod 112 is installed in the front clamping member 111. A grinder 113 is fixedly connected to the telescopic part on the rear side of the electric push rod 112, and the grinder 113 is slidably connected to the clamping member 111 on the rear side.

[0035] like Figure 2 As shown, the latch assembly includes an insertion rod 14, and the two insertion rods 14 are respectively slidably connected to the left and right sides of the support frame 1. A return spring 15 is connected between the two insertion rods 14 and the support frame 1. The two return springs 15 are both wound around the adjacent insertion rods 14, and the insertion rods 14 are snap-fitted with the adjacent opening and closing members 13.

[0036] like Figure 7 As shown, it also includes a stabilizing mechanism for straightening somewhat bent cables, the stabilizing mechanism is arranged on the sliding frame 11, and the stabilizing mechanism includes an extrusion frame 2, the extrusion frames 2 are symmetrically distributed on the left and right sides of the front of the sliding frame 11, respectively, and the guide frames 24 are symmetrically distributed on the left and right sides are fixed to the support frame 1, and the two guide frames 24 are slidably connected with wedge frames 21, and compression springs 23 are connected between the wedge frames 21 and the adjacent guide frames 24, and the sides of the wedge frames 21 close to each other are fixed with fixing parts 22, and the two fixing parts 22 are both arranged in an arc shape that fits the cable, and the extrusion frame 2 and the adjacent wedge frames 21 are squeezed and matched.

[0037] Place the device above the cable to be polished, first pull the rod 14 upward to withdraw it from the opening and closing piece 13, the reset spring 15 will be deformed, and then pull the opening and closing piece 13 outward, and then lift the cable to be polished upward to slightly above the opening and closing piece 13, then push the opening and closing piece 13 inward to close it, release the rod 14, and under the elastic force of the reset spring 15, the rod 14 will automatically slide downward to be inserted into the adjacent opening and closing piece 13, at this time the opening and closing piece 13 has been stuck by the rod 14, and then put down the cable, the cable will fall on the opening and closing piece 13 under the action of its own gravity, turn the first screw 12 clockwise, thereby driving the sliding frame 11 to move downward together with the extrusion frame 2, the sliding frame 11 moving downward will press on the cable, and the sliding frame 11 and the opening and closing piece 13 cooperate to fix the cable.

[0038] Then, the second screw 18 is turned in the positive direction, thereby driving the adjustment frame 19 to move downward, and then driving the positioning member 111, the electric push rod 112, the grinder 113, etc. to move downward. When the grinder 113 fits the cable, stop turning the second screw 18, first control the grinder 113 to grind the cable, the storage spring 110 will deform slightly, and at the same time control the electric slide rail 16 to drive the sliding member 17 to rotate, thereby driving the grinder 113 to rotate around the cable, the grinder 113 will grind the cable one circle, and then control the electric push rod 112 to drive the grinder 113 to move backward, so that the grinder 113 rotates one circle and then moves backward a little, until the area of ​​the cable to be polished is completely polished.

[0039] When the downwardly moving extrusion frame 2 contacts the inclined surface of the wedge frame 21, the extrusion frame 2 will squeeze the wedge frame 21 to drive the fixing member 22 to move inward, the compression spring 23 will be deformed, and the fixing member 22 moving inward will straighten the slightly bent and deformed cable. As the extrusion frame 2 continues to move downward to pass over the wedge frame 21, under the elastic force of the compression spring 23, the wedge frame 21 will drive the fixing member 22 to move outward and reset. At this time, the cable has been clamped from the upper and lower sides by the sliding frame 11 and the opening and closing member 13. When the cable is polished, the first screw 12 is first turned counterclockwise to drive the sliding frame 11 to move upward and away from the cable.

[0040] According to the previous steps, the plug rod 14 is pulled out and the opening and closing piece 13 is pulled outward. The opening and closing piece 13 no longer supports the cable, and the cable will fall directly to the ground. The staff can perform subsequent operations on the polished cable. In summary, the extrusion frame 2, the wedge frame 21, the fixing piece 22 and the like cooperate with each other to straighten the slightly bent cables. Secondly, the straightened cables are fixed by the sliding frame 11 and the opening and closing piece 13 to ensure that the cables will not shake or shift during the polishing process, thereby ensuring the accuracy and effect of the polishing. Then, the electric slide rail 16 and the electric push rod 112 cooperate with each other to enable the polisher 113 to rotate around the cable and move along the polishing area, which not only realizes the comprehensive polishing of the cable, but also improves the work efficiency and reduces the complexity and labor intensity of manual operation.

[0041] Embodiment 2: Based on embodiment 1, Figure 8-Figure 11 As shown, it also includes a transport mechanism for steadily lifting the device into the cable trench, the transport mechanism is arranged on the support frame 1, the transport mechanism includes a rotating circle 3, the rotating circles 3 symmetrically distributed on the left and right are rotatably connected to the support frame 1, the support frame 1 is fixedly connected with telescopic members 31 distributed in pairs, the telescopic parts of the two telescopic members 31 are rotatably connected to the sliding bracket 381, the two sliding brackets 381 are slidably connected to the load-bearing frame 38, the two sliding brackets 381 are rotatably connected to the winding member 33, the winding members 33 are provided with a disc handle on the side away from each other, the two winding members 33 are wound with a pull rope 32, the movable end of the pull rope 32 is fixedly connected to the adjacent rotating circle 3, the two winding members 33 are fixedly connected with a ratchet 34, and the two sliding brackets 381 are provided with a clamping assembly.

[0042] like Fig.10 and Fig.11 As shown, the locking assembly includes a connecting member 37, and the two connecting members 37 are respectively fixed to the adjacent sliding brackets 381. The two connecting members 37 are rotatably connected to a pawl 35. A torsion spring 36 is connected between the pawl 35 and the adjacent connecting member 37. The two torsion springs 36 are respectively wound around the adjacent connecting members 37, and the two pawls 35 are both locked in the teeth of the adjacent ratchet 34.

[0043] Initially, the pull rope 32 is wound around the reel 33, and the telescopic member 31 is in a retracted state. The device is suspended on two load-bearing frames 38. Since some cables are laid through underground pipes or tunnels, in order to enable the device to be smoothly transported to the cable trench, the specific operations are as follows: one staff member first holds the support frame 1, and the other staff member rotates the load-bearing frame 38 outward 90° and places it on the left and right sides of the top of the cable trench. The load-bearing frames 38 will be placed facing each other, and the load-bearing frames 38 will drive the rotating circle 3 to rotate 90° through the sliding bracket 381 and the pull rope 32, so that the device is suspended just above the cable trench, and then the pawl 35 is pressed downward to rotate it backward until it is disengaged from the ratchet 34, and the torsion spring 36 will be twisted. At this time, under the action of the device's own gravity, the device will descend into the cable trench, the reel 33 will rotate backward to release the pull rope 32, and the telescopic member 31 will gradually extend.

[0044] When the device is lowered to the appropriate position, the pawl 35 is released, and under the action of the torsion spring 36, the pawl 35 will rotate forward until it is engaged with the ratchet 34, and the winding member 33 will no longer rotate to release the pull rope 32. The cable can be polished according to the above steps. When the polishing is completed, the staff can hold the disc handle and rotate it forward, thereby driving the winding member 33 to rotate forward to reel in the pull rope 32, and then driving the device to be lifted out of the cable trench. In summary, the load-bearing frame 38, the winding member 33, and the pull rope 32 cooperate with each other to achieve the function of smoothly lifting in and out of the cable trench. At the same time, the pawl 35 and the ratchet 34 are used to hold the winding member 33 in place, which ensures the stability and safety of the device during operation and improves the efficiency and convenience of operations in the cable trench.

[0045] like Fig.12 and Fig.13 As shown, it also includes a collecting mechanism for containing the debris from grinding, the collecting mechanism is arranged on the symmetrically distributed opening and closing parts 13, the collecting mechanism includes a collecting box 4, the left and right symmetrically distributed collecting boxes 4 are respectively fixed to the front sides of the opening and closing parts 13, and the two collecting boxes 4 are slidably connected with a first extrusion member 41, and a linear spring 42 is connected between the first extrusion member 41 and the adjacent collecting box 4, and the two linear springs 42 are both wound around the adjacent collecting boxes 4. A symmetrically distributed second extrusion member 43 is fixed to one side of the support frame 1 close to the collecting box 4, and a slope is provided on the side of the second extrusion member 43 close to each other, and the first extrusion member 41 and the slope of the adjacent second extrusion member 43 are squeezed and matched.

[0046] When the grinder 113 is grinding the cable, the grinding debris will fall into the collection box 4. When the opening and closing member 13 is pulled outward, the opening and closing member 13 will drive the collection box 4 and the first extrusion member 41 to move outward together. When the first extrusion member 41 moving outward contacts the inclined surface of the second extrusion member 43, the second extrusion member 43 will resist the first extrusion member 41 to move it backward, and the linear spring 42 will be deformed. The first extrusion member 41 moving backward will push the debris in the collection box 4 together, making it easier for the staff to collect the debris. The gathered debris is taken out. Similarly, when the opening and closing piece 13 moves inward, the collecting box 4 and the first extrusion piece 41 move inward together. When the inwardly moving first extrusion piece 41 separates from the second extrusion piece 43, under the elastic force of the linear spring 42, the first extrusion piece 41 moves forward and resets. In summary, through the mutual cooperation and ingenious design of the collecting box 4, the first extrusion piece 41, and the second extrusion piece 43, the grinding debris can be easily cleaned, thereby improving work efficiency and convenience of operation.
