Description
Technical Field
[0001] This utility model relates to the field of power maintenance technology, and in particular to an automatic climbing folding maintenance shielding device. Background Technology
[0002] The power system is an indispensable infrastructure for the operation of modern society, and the safe and stable operation of the power grid is crucial for ensuring socio-economic activities. With the in-depth advancement of the construction of new distribution networks, the workload of installing pole-mounted intelligent equipment for live-line work has increased dramatically. However, the capacity of live-line work on distribution networks is limited, making it difficult to fully support the needs of distribution network projects. Utilizing non-live-line workers to complete the preliminary installation work can greatly reduce the workload of live-line work and effectively solve the problem of insufficient capacity for live-line work.
[0003] During power grid maintenance and repair, according to regulations, when working close to high-voltage live conductors, relevant shielding measures must be taken before work can begin. However, the existing shielding plates are very bulky, and it is very inconvenient for workers to install and dismantle them, climb and descend the poles at each maintenance point, which affects work efficiency and causes a significant increase in the resource input and project time for live-line work in distribution network projects.

[0004] Therefore, the purpose of this utility model is to provide an automatic climbing folding maintenance shielding device, which has the characteristics of high automation, high operation efficiency and convenience.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

Multiple lifting devices are evenly arranged along the circumference of the inner side of the collar assembly, and a foldable or unfoldable shielding plate is provided on the outer side of the collar assembly. The lifting devices can be attached to and pressed against the outer wall of the pole along the circumference. Each lifting device includes a wheel system, a drive unit for driving the collar assembly to rise or fall along the pole, and a braking assembly for fixing the collar assembly to the pole.
[0007] The shielding plate includes a first sector plate fixed to the outside of the collar assembly and a second sector plate rotatably connected to one side of the first sector plate.
[0008] A drive shaft is provided on the outer side of the collar assembly, and a drive motor is connected to the drive shaft; one side of the second sector plate is provided on the drive shaft, and when the drive shaft rotates, it drives the second sector plate to rotate along one side.
[0009] There are two drive shafts, which are symmetrically distributed in the diameter direction of the collar assembly. There are two sets of shielding plates, each set including a first sector plate and a second sector plate. When the drive shaft drives the second sector plate to rotate and unfold, the shielding plate forms a circular shielding surface on the outside of the collar assembly.
[0010] The lifting device includes a wheel frame in the shape of an isosceles triangle. The wheel frame includes first hinge points distributed on two base angles of the isosceles triangle, and a first pulley is provided on the first hinge point. The apex angle of the isosceles triangle wheel frame forms a second hinge point, and a second pulley driven by a motor is provided on the second hinge point. The driving unit is a drive motor installed inside the second pulley. Tracks are provided around the first pulley and the second pulley.
[0011] The top of the wheel frame is provided with a pushing device. One end of the pushing device is hinged to the second hinge point, and the other end is fixedly connected to the collar assembly. The pushing device can push the lifting device to fit against the outer wall of the rod.
[0012] A bottom edge rod is connected between the two first hinge points, and a first buffer rod is provided between the second hinge point and the midpoint of the bottom edge rod.
[0013] A second buffer rod is provided between the first hinge point and the second hinge point.
[0014] The collar assembly is composed of two semi-circular collars, which are connected to each other through connecting ends located at both ends.
[0015] The braking assembly includes a clamping device disposed below the collar assembly. The clamping device includes a clamping frame fixed to the lower surface of the collar assembly. The clamping frame is connected to a tightening nut, and one end of the tightening nut is connected to an annular clamping block.
[0016] The beneficial effects of this utility model are:
[0017] 1. Improved work efficiency: Compared with traditional maintenance shielding plates, this device can automatically rise or fall along the utility pole, reducing the time spent on manual climbing and installing / removing shielding plates, thereby greatly improving the efficiency of power grid maintenance and repair work.
[0018] 2. Reduce workload: Automated operation can reduce the workload of operators, especially avoiding the need to frequently carry heavy shielding boards for high-altitude operations, thus reducing the demand for physical labor.
[0019] 3. Enhanced Safety: The automatic climbing mechanism and foldable / deployable shielding design provide necessary protection for workers while maintaining a safe distance. Furthermore, pressure sensors ensure sufficient contact force between the lifting device and the utility pole, preventing slippage and enhancing operational safety.
[0020] 4. The collar assembly consists of two semi-circular collars, making it easy to carry and assemble, increasing the flexibility and applicability of the equipment. The use of tracked wheels as the lifting mechanism, along with the foldable shielding plate, results in a compact overall structure that occupies little space when not in use, facilitating transportation and storage.

[0028] Reference Figure 1-2 This utility model proposes an automatic climbing and folding maintenance shielding device, including a ring-shaped collar assembly 1 that can be set around the pole body 4 of a utility pole. Multiple lifting devices 3 are evenly arranged along the circumferential direction on the inner side of the collar assembly 1, and a foldable or unfoldable shielding plate 2 is arranged on the outer side of the collar assembly 1. The lifting devices 3 can be attached to and pressed against the outer wall of the pole body 4 along the circumferential direction. The lifting device 3 is a wheel system device, which includes a drive unit for driving the collar assembly 1 to rise or fall along the pole body 4, and a braking assembly for fixing the collar assembly 1 to the pole body 4.
[0029] Reference Figure 2-3 The shielding plate 2 includes a first sector plate 20 fixed to the outside of the collar assembly 1, and a second sector plate 21 rotatably connected to one side of the first sector plate 20.

One side of the second sector plate 21 is set on the drive shaft 22. When the drive shaft 22 rotates, it drives the second sector plate 21 to rotate along one side. The foldable and unfoldable shielding design can provide necessary protection for workers while maintaining a safe distance.
[0031] There are two drive shafts 22, which are symmetrically distributed in the diameter direction of the collar assembly 1. There are two sets of shielding plates 2, each set including a first sector plate 20 and a second sector plate 21. When the drive shaft 22 drives the second sector plate 21 to rotate and unfold, the shielding plate 2 forms a circular shielding surface on the outside of the collar assembly 1.
[0032] Furthermore, compared to traditional maintenance shielding panels, this device can automatically rise or fall along the utility pole, reducing the time spent on manual climbing and installing / removing shielding panels, thereby greatly improving the efficiency of power grid maintenance and repair work.
[0033] Reference Figure 6 The lifting device 3 is a tracked wheel device, which includes a wheel frame 30 in the shape of an isosceles triangle. The wheel frame 30 includes a first hinge point 300 distributed on the two base angles of the isosceles triangle. A first pulley 32 is provided on the first hinge point 300.

The driving unit is a drive motor installed in the second pulley 31. Tracks 34 are covered on the first pulley 32 and the second pulley 31.
[0034] A pushing device 35 is provided on the top of the wheel frame 30. One end of the pushing device 35 is hinged to the second hinge point 301, and the other end is fixedly connected to the collar assembly 1. The pushing device 35 can push the lifting device 3 to fit against the outer wall of the rod 4. Specifically, the pushing device 35 can be a hydraulic or pneumatic device. When the lifting device 3 is activated, the pushing device 35 pushes the track wheel assembly to fit and press against the outer wall of the rod to generate sufficient friction to drive the entire device to move up and down, thereby achieving lifting. The second pulley 31 is the drive wheel, with a built-in drive motor. The motor is controlled by the control unit. When the shielding device reaches the designated position, the drive motor can also act as a brake. The control unit controls it to be in a locked state. At the same time, the pushing device 35 increases the pressure under the control of the control unit, so that the lifting device 3 is fixed on the outer wall of the rod 4. Preferably, the track 34 is made of wear-resistant rubber, and the contact surface with the outer wall of the rod 4 is provided with stripes to increase the coefficient of friction.

[0036] A second buffer rod 304 is provided between the first hinge point 300 and the second hinge point 301. Specifically, the first buffer rod 302 and the second buffer rod 304 can increase the smoothness of the lifting process.
[0037] Furthermore, the collar assembly 1 is equipped with a pressure sensor 33 for detecting the pressure state of the lifting device 3 pressing against the outer wall of the pole 4. The pressure sensor ensures sufficient friction between the lifting device 3 and the utility pole to prevent slippage and enhance operational safety. The collar assembly 1 also includes a control unit and a communication unit, allowing for remote monitoring and adjustment, making the entire maintenance process more intelligent and efficient, and facilitating management and coordination. The collar assembly 1 also contains a battery module to provide power to the entire automated system.
[0038] Automated operation can reduce the workload of workers, especially by avoiding the need to frequently carry heavy shielding boards for high-altitude operations, thus reducing the demand for physical labor.
[0039] The collar assembly 1 is composed of two semi-circular collars, which are connected to each other via connecting ends 12 at both ends. The collar assembly 1, composed of two semi-circular collars, is easy to carry and assemble. In use, the two semi-circular collars are fitted onto the outer wall of the rod 4, and then the two ends are connected to form a ring. The lifting device 3 and the shielding plate 2 can be remotely activated to reach the designated work location.
[0040] Preferably, a first sector plate 20 and a second sector plate 21 are respectively provided on the outer side of each semi-circular ring.
