For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] In the description of the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include the first feature being in direct contact with the second feature, or may include the first feature being in contact with the second feature through another feature between them instead of being in direct contact. Moreover, a first feature being "above", "above" and "above" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0044] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0045] like Figure 1-Figure 13 As shown, the present invention provides a pole-mounted working platform. The pole-mounted working platform includes a bracket 1, a fastening device 2 and a lifting device 3. The bracket 1 is provided with a support member 11 for providing foot support for the operator; the fastening device 2 is provided on the bracket 1, and is used to fasten the bracket 1 to the pole; the lifting device 3 is provided on the bracket 1, and includes a traction rope 31, a self-locking winch 32 and a connecting member 33, one end of the traction rope 31 is wound around the self-locking winch 32, and the other end is connected to the connecting member 33, and the connecting member 33 is constructed to be detachably connected to an external component.

[0046] The support 11 of the pole-mounted work platform provides foot support for the workers, and can provide continuous and stable support force for the workers, making the workers' high-altitude operations safer and more efficient, and reducing the risk of workers falling from heights; the lifting device 3 can lift the pole-mounted work platform and the objects to be lifted, such as the grounding wire, to a preset height of the pole, reducing the labor intensity and operation difficulty of the workers.

[0047] Specifically, Figure 1-Figure 4As shown, the fastening device 2 is a strap, which can quickly fix the supporting work platform of the pole to the pole, and at least the upper and lower ends of the bracket 1 are provided with straps to improve the stability of the supporting work platform of the pole fixed to the pole. Optionally, the fastening device 2 can also be a clamp or other structure with a fastening function. A plurality of support members 11 can be provided on the bracket 1 according to actual application conditions, and are arranged at intervals along the height direction of the bracket 1. A plurality of support members 11 of different heights can provide foot supports of different heights for the operator, which is convenient for the operator to adjust the working posture. In this embodiment, the number of support members 11 is set to three.

[0048] Preferably, if Figure 1 and Figure 6 As shown, the bracket 1 also includes a plurality of one-way buckles 12, which are used to reversely lock the grounding wire. Specifically, the one-way buckle 12 includes a wedge-shaped sawtooth block 121 and a stopper 122, the wedge-shaped sawtooth block 121 is hinged to the bracket 1, and the stopper 122 is fixedly arranged on the bracket 1. A gap is left between the wedge-shaped sawtooth block 121 and the stopper 122 for the grounding wire to pass through. An elastic member is arranged on the wedge-shaped sawtooth block 121, and the elastic member provides elastic force for the wedge-shaped sawtooth block 121, so that the wedge-shaped sawtooth block 121 cooperates with the stopper 122 to maintain the tendency of one-way clamping the grounding wire. In this embodiment, the one-way buckle 12 is arranged on the side of the uppermost support member 11, and the number is three, which meets the requirement that three grounding wires need to be suspended in a general line.

[0049] When hanging the grounding wire, the grounding wire can be passed through the one-way buckle 12 from the bottom. At this time, the wedge-shaped serrated block 121 clamps the grounding wire under the action of the elastic member to prevent the grounding wire from falling, so that the grounding wire can only be lifted upward and cannot fall. The operator does not need to bear the weight of the entire grounding wire when hanging the grounding wire, thereby reducing the labor intensity of the operator.

[0050] Furthermore, if Figure 1 , Figure 3 and Figure 7 As shown, the bracket 1 includes a bracket body 15 and a support member 11. The support member 11 is connected to the bracket body 15 via a folding triangular bracket 13. The folding triangular bracket 13 can be unfolded and folded to switch the support member 11 between a working state and a folded state. When the supporting working platform of the pole is fastened to the pole and needs to provide foot support for the operator, the folding triangular bracket 13 can be unfolded to put the support member 11 in a working state; when the supporting working platform of the pole is hoisted to a predetermined height of the pole or hoisted from the pole to the ground, the folding triangular bracket 13 can be folded to put the support member 11 in a folded state to reduce the volume of the supporting working platform of the pole, making the operation process more convenient. The folding triangular bracket 13 belongs to the prior art, and its structure and principle will not be described in detail here.

[0051] More specifically, the support 1 is a frame structure, including two side bars and at least two cross bars, and the cross bars are designed to be V-shaped to adapt to the shape of the pole, so that the pole-matching work platform is closer to the pole. Figure 5 As shown, when the support member 11 is in working state, a V-shaped opening is provided on one side close to the pole, so that the support member 11 fits the pole more closely. Optionally, the bracket 1 can be made of a stainless steel square tube.

[0052] Preferably, if Figure 1 and Figure 5 As shown, a hanging rod 14 is also horizontally arranged on one side of the support member 11 away from the bracket body 15, and a gap is left between the hanging rod 14 and the support member 11. Specifically, two support rods are extended on both sides of the support member 11, and a hanging rod 14 is arranged between the two support rods. When the lifting device 3 hoists the grounding wire from the ground to the supporting working platform of the pole, the insulating operating rod of the grounding wire can be temporarily hung on the hanging rod 14. When all the required grounding wires are hoisted from the ground to the supporting working platform of the pole, the grounding wires are hung on the line one by one.

[0053] For example, Figure 8 As shown, the support member 11 is configured as a multi-layer plate structure, which includes a support layer 111, a main body layer 112, a reinforcement layer 113 and an insulating and anti-slip layer 114 from bottom to top. The multi-layer plate structure design reduces the weight of the support member 11 while maintaining a certain strength, which not only reduces the labor intensity of the staff, but also ensures the safety of the support member 11. Optionally, the support layer 111 is made of glass fiber board, the main body layer 112 is a lightweight structure, using a honeycomb PC board, the reinforcement layer 113 is an aluminum plate, and the insulating and anti-slip layer 114 is a glass fiber board.

[0054] Specifically, Fig. 9 As shown, the self-locking winch 32 includes a frame, a driving member 321, a worm gear 322, a first gear 323 and a roller 324, wherein the driving member 321 is arranged on the frame, the worm gear 322 is connected to the output shaft of the driving member 321, the roller 324 is rotatably arranged on the frame, the first gear 323 is coaxially arranged at one axial end of the roller 324 and meshes with the worm gear 322, and the driving member 321 drives the first gear 323 to rotate through the worm gear 322, thereby rotating the driving roller 324 connected to the first gear 323. The traction rope 31 is wound around the roller 324, and the driving member 321 drives the roller 324 to rotate so that the traction rope 31 is tightened or released, thereby realizing the lifting or traction function. Optionally, the driving member 321 is a motor, and the worm gear 322 and the first gear 323 can also be replaced by a spiral transmission mechanism or a ratchet mechanism with a self-locking function, which will not be repeated here.

[0055] Furthermore, the self-locking winch 32 further includes a second gear 325 and a reciprocating screw 326. The second gear 325 is rotatably arranged on the frame and meshes with the first gear 323. The reciprocating screw 326 is also rotatably arranged on the frame, and a third gear 327 meshing with the second gear 325 is arranged at one axial end of the reciprocating screw 326 to drive the reciprocating screw 326 to rotate. A slider is sleeved on the reciprocating screw 326. When the reciprocating screw 326 rotates, the slider can move the traction rope 31 so that the traction rope 31 is evenly wound around the roller 324. More specifically, the self-locking winch 32 further includes a main box, in which a power supply and a remote control switch assembly are arranged. The operator can remotely control the self-locking winch 32, further improving the convenience of the operation.

[0056] Preferably, if Fig.10 and Fig.11 As shown, the supporting work platform for the electric pole also includes a mounting plate 4, and the lifting device 3 is fixedly mounted on the bottom of the mounting plate 4. At least one pin 115 is provided at the bottom of the support 11, and the mounting plate 4 is provided with a number of holes 41 that is the same as the number of the pins 115. The pins 115 can be inserted into the holes 41, so that the mounting plate 4 with the lifting device 3 installed can be quickly and detachably installed on the support 11. Specifically, as Fig.11 As shown, the pin 115 includes a main body and a protrusion disposed at the end of the main body, and the clamping hole 41 includes a through hole, a slideway and a blind hole. The through hole and the blind hole have the same diameter as the protrusion. The through hole and the blind hole are respectively disposed at both ends of the slideway. The pin 115 can be inserted into the through hole and clamped and fixed with the blind hole after passing through the slideway. Such a structural design makes it impossible for the pin 115 to escape from the clamping hole 41 when only subjected to gravity after the pin 115 is clamped into the clamping hole 41, thereby ensuring the firmness of the connection between the mounting plate 4 and the support member 11. It is understandable that the number of the pin 115 and the clamping hole 41 can be flexibly set according to the area size of the support member 11 and the mounting plate 4. Furthermore, the mounting plate 4 and the support member 11 are also provided with pin holes of the same size. When the folding triangular bracket 13 is folded so that the support member 11 and the mounting plate 4 are in a vertical state, the pin 115 can be inserted into the pin hole to prevent the mounting plate 4 from falling off from the support member 11.

[0057] like Fig.12 and Fig.13As shown, the present invention also provides an operating method for a pole-mounted working platform, which is used to install and operate the pole-mounted working platform, comprising the following steps: an operator climbs onto the pole and carries the connecting piece 33 together with the traction rope 31 to the top of the pole, and fixes the connecting piece 33 on the cross arm at the top of the pole; starts the self-locking winch 32 of the lifting device 3 to lift the pole-mounted working platform to a preset height; the operator uses the fastening device 2 to fasten the pole-mounted working platform to the pole; the operator removes the connecting piece 33 from the cross arm at the top of the pole and lowers it to the ground, connects the connecting piece 33 to an object to be lifted on the ground, such as a grounding wire, and then starts the self-locking winch 32 of the lifting device 3 to lift the object to be lifted, such as the grounding wire, to the pole-mounted working platform. The operating method for the pole-mounted working platform has the advantages of high efficiency, convenience, high safety, and strong adaptability, and can be widely used in the maintenance or testing of power facilities.
