[0026] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figures 1 to 6 shown, a safety operating platform 4 is installed on a high-column signal machine, including a ladder 1. The ladder 1 enables the user to climb to a high place. The top and middle parts of the ladder 1 are respectively provided with an upper hoop 2 and a middle hoop 3 for fixing on the high column. The upper hoop 2 and the middle hoop 3 enable the ladder 1 to be stably installed on the electric pole. An operating platform 4 is installed on the middle hoop 3. The operating platform 4 enables the user to perform operations at a high altitude, and the operating platform 4 is arranged to be able to rotate from one side of the ladder 1 to the opposite side of the ladder 1 on the middle hoop 3.

[0028] A circle of first wave grooves 5 is provided on the surface of the middle hoop 3. One end of the operating platform 4 is provided with a first sliding rod 6 that can slide in the first wave grooves 5. When the operating platform 4 is located at the position opposite to the ladder 1, the first sliding rod 6 is located at the trough position of the first wave grooves 5. When the first sliding rod 6 slides inside the first wave grooves 5, the angle of the operating platform 4 can be adjusted.

[0029] One end of the operating platform 4 sleeved outside the middle hoop 3 is provided with a first outer hoop 7, and the first sliding rod 6 is fixedly installed on the inner surface of the first outer hoop 7.

[0030] A push rod 8 is equidistantly installed along the circumferential direction on the outside of the first outer layer clamping hoop 7. The first outer layer clamping hoop 7 enables the push rod 8 to be fixedly installed on the operating platform 4. At the same time, when the push rod 8 rotates, it can drive the operating platform 4 to rotate. One side of the ladder 1 is rotatably installed with a pry bar 9. The pry bar 9 contacts the push rod 8. When the pry bar 9 rotates, it can drive the push rod 8 to rotate, thereby driving the operating platform 4 to move. The front end of the pry bar 9 extends obliquely downward between two adjacent push rods 8, and the pry bar 9 drives the operating platform 4 to rotate outside the middle clamping hoop 3 through the upward warping of the front end.

[0031] The pry bar 9 includes a front end rod body 91 and a rear end rod body 92. The rear end of the front end rod body 91 is rotatably installed at the front end of the rear end rod body 92. A convex block 93 is provided at the front end of the rear end rod body 92. When the front end rod body 91 and the rear end rod body 92 are on the same straight line, the tail end of the rear end rod body 92 supports on the convex block 93. Hold the rear end rod body 92 and press it down to pry the pry bar 9. When the pry bar 9 pries the push rod 8, the front end rod body 91 is blocked by the convex block 93, which will keep the front end rod body 91 and the rear end rod body 92 stable, so that the push rod 8 can move stably.

[0032] Cross plates 10 are installed on both sides of the ladder 1. The middle clamping hoop is connected between the front ends of the two cross plates 10. The pry bar 9 is rotatably installed on one of the cross plates 10. The cross plates 10 enable the ladder 1 and the middle clamping hoop to be stably installed.

[0033] The tail end of the cross plate 10 is rotatably installed on the ladder 1. The width of the operating platform 4 is smaller than the width of the ladder 1. When the ladder 1 is perpendicular to the cross plate 10, one end of the operating platform 4 away from the middle clamping hoop can be sleeved by the ladder 1.

[0034] A "U"-shaped inserting rod 11 is inserted on the cross plate 10 where the pry bar 9 rotates. The inserting rod 11 fixes the pry bar 9 on the cross plate 10 by sleeving on the pry bar 9. The "U"-shaped inserting rod 11 enables the pry bar 9 to be stable on the outer wall of the cross plate 10, preventing accidental touch and danger during operation.

[0035] One end of the operating platform 4 away from the first outer layer clamping hoop 7 is provided with a diagonal brace 12. The bottom end of the diagonal brace 12 is provided with a second outer layer clamping hoop 13. A lower clamping hoop 14 for fixing on the high pole is arranged inside the second outer layer clamping hoop 13. The diagonal brace 12 forms a triangle between the operating platform 4 and the electric pole, enabling the operating platform 4 to be stable on the electric pole. And a second wave groove 15 adapted to the first wave groove 5 is arranged on the surface of the lower clamping hoop 14. A second sliding rod 16 for sliding in the second wave groove 15 is arranged on the surface of the second outer layer clamping hoop 13. The second sliding rod 16 slides inside the second wave groove 15, enabling the diagonal brace 12 to be stably installed on the lower clamping hoop 14, achieving a stable effect.

[0036] The top end of the lower hoop 14 is connected to the bottom end of the middle hoop 3 through a connecting plate 17. The connecting plate 17 can limit the distance between the middle hoop 3 and the lower hoop 14, enabling the device to be stably installed and preventing danger caused by shaking.

[0037] When in use, first fix the top end of the ladder 1 on the utility pole through the upper hoop 2, then fix the middle hoop 3 on the utility pole. Rotate the diagonal brace 12 to fix the lower hoop 14 on the utility pole. Take out the insertion rod 11 and press down the pry bar 9 to drive the front rod body 91 of the pry bar 9 to contact the push rod 8. When the front rod body 91 starts to pry the push rod 8, the front rod body 91 and the rear rod body 92 are blocked by the convex block 93 to keep the front rod body 91 and the rear rod body 92 in a vertical state, facilitating prying the push rod 8. When the front rod body 91 of the pry bar 9 is moved upward, the front rod body 91 and the rear rod body 92 will rotate, facilitating the front rod body 91 to enter the next push rod 8. Slide the first sliding rod 6 inside the first wavy groove 5. When the first sliding rod 6 slides, it can rotate the push rod 8 to rotate the workbench 4. At the same time, when the workbench 4 rotates, the lower hoop 14 on the diagonal brace 12 will slide inside the second wavy groove 15 through the second sliding rod 16, enabling the workbench 4 to rotate stably on the utility pole. When the workbench 4 rotates to the appropriate angle, construction operations are carried out on the workbench 4. After the construction is completed, continue to press down the pry bar 9, rotate the workbench 4 to the initial position, and store the workbench 4.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
