[0002] The operation of the power grid is inseparable from the support of transmission lines. As an important part of the power system, transmission lines have large transmission capacity, long power transmission distance, and high line voltage level. They are the backbone of the power grid. When performing circuit maintenance on transmission lines, workers are usually required to climb to high altitudes to repair the circuits, which is inconvenient, dangerous, and lacks safety guarantees.

[0003] In document CN202122972495.2, a transmission line aerial work maintenance auxiliary anti-fall device is proposed, comprising a base plate, a support rod is fixed on the top of the base plate, a top plate is fixed on the top of the support rod, a motor is fixed on the top of the base plate, a screw is fixed on the output shaft end of the motor, the top of the screw is rotatably connected to the top plate through a bearing, and the outer side of the screw is threadedly connected to a lifting plate. The present invention can prevent maintenance tools from falling to the ground by setting a collection frame, avoid tools from injuring pedestrians and vehicles below, and enhance safety performance. Through the mutual cooperation of the motor, screw rod, lifting plate and slide plate, the height of the collection frame can be adjusted for easy use. By setting a buffer mechanism and a rubber plate, the impact force on the baffle can be reduced when the tool falls, which can not only avoid damage to the tool, but also extend the service life of the baffle.

[0004] When the auxiliary anti-fall device for high-altitude maintenance of transmission lines proposed in the above-mentioned cited patent is in use, the maintenance personnel stand on the upper end of the collection frame, and use the motor to drive the lead screw to rotate, so as to drive the collection frame to the lower end of the maintenance line to inspect the line. When the maintenance personnel stand on the upper end of the collection frame to work, the inner wall of the collection frame is not provided with any protective measures, which makes the workers face the safety hazard of falling during the high-altitude maintenance work.

[0005] In view of the above problems, a circuit maintenance high altitude anti-fall protection device which is easy to operate is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide an easy-to-operate high-altitude anti-fall protection device for circuit maintenance. By using this device to work, the problem in the above background that when the maintenance personnel stand on the upper end of the collection frame to work, the inner wall of the collection frame is not provided with any protection measures, which makes the workers have a safety hazard of falling during high-altitude maintenance operations is solved.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a circuit maintenance high-altitude anti-fall protection device that is easy to move, comprising a bottom plate and universal wheels fixedly installed around the lower end of the bottom plate, a lifting assembly fixedly installed in the middle of the upper end of the bottom plate, a second erection plate fixedly installed around the upper end of the bottom plate through support rods, a standing protection assembly fixedly installed on the upper end of the second erection plate, and the standing protection assembly is used to protect the maintenance personnel standing on the upper end of the standing protection assembly;

An anti-falling mechanism is movably installed around the inner wall of the collecting frame mechanism. The collecting frame mechanism is used to support maintenance personnel standing on its upper end to work. The intercepting mechanism is used to adjust the setting height of one side of the inner wall of the collecting frame mechanism to facilitate maintenance personnel to enter and exit the interior of the collecting frame mechanism. The anti-falling mechanism is used to be bound to the waist of the maintenance personnel to provide protection when the maintenance personnel are working.

[0009] Furthermore, the collection frame mechanism includes a rectangular frame and an inner groove opened in the middle of one side of the outer wall of the rectangular frame, a plurality of linear and evenly spaced penetrating grooves are opened on the upper end of the bottom surface of the inner wall of the inner groove, and circular grooves are opened on both sides of the upper end of the inner wall of the inner groove.

[0010] Furthermore, a connecting groove is provided around the upper end of the inner wall of the rectangular frame, and a limiting groove is provided in the middle of the upper and lower ends of the inner wall of the connecting groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the maintenance personnel first stand in the inner cavity of the rectangular frame, and drive the collection frame mechanism to rise to the lower end of the maintenance line by starting the lifting assembly. While the collection frame mechanism rises, the maintenance personnel binds the binding belt around his waist. When the maintenance personnel walks at the upper end of the rectangular frame, the rope will drive the long pole and the embedded block and the pressure block fixed at one end of the long pole to slide in the inner cavity of the connecting groove and the limit groove. Such an arrangement can provide anti-fall protection for the maintenance personnel through the binding belt without affecting the movement of the maintenance personnel, thereby improving the safety of the maintenance personnel at work.

[0021] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0022] Combination Figure 1The present invention provides a high-altitude anti-fall protection device for circuit maintenance that is easy to move, including a base plate 1 and universal wheels 2 fixedly installed around the lower end of the base plate 1, a lifting component 3 is fixedly installed in the middle of the upper end of the base plate 1, a second erection plate 4 is fixedly installed around the upper end of the base plate 1 through support rods, and a standing protection component 5 is fixedly installed on the upper end of the second erection plate 4. The standing protection component 5 is provided to protect the maintenance personnel standing on the upper end of the standing protection component 5.

[0023] The present invention will be further described below in conjunction with the embodiments.

[0024] Embodiment 1:

[0025] See also Figure 1-Figure 4 The standing protection component 5 includes a collecting frame mechanism 51 and an intercepting mechanism 52 movably installed on one side of the upper end of the collecting frame mechanism 51. An anti-falling mechanism 53 is movably installed around the inner wall of the collecting frame mechanism 51. The collecting frame mechanism 51 is used to support maintenance personnel standing on its upper end to work. The intercepting mechanism 52 is used to adjust the setting height of one side of the inner wall of the collecting frame mechanism 51 to facilitate maintenance personnel to enter and exit the interior of the collecting frame mechanism 51. The anti-falling mechanism 53 is used to be bound to the waist of the maintenance personnel to protect them when they are working.

[0026] The collecting frame mechanism 51 includes a rectangular frame 511 and an inner groove 512 opened in the middle of one side of the outer wall of the rectangular frame 511. The upper end of the bottom surface of the inner wall of the inner groove 512 is linearly and evenly spaced with a plurality of penetrating grooves 513, and circular grooves 514 are opened on both sides of the upper end of the inner wall of the inner groove 512.

[0027] A connecting groove 515 is provided around the upper end of the inner wall of the rectangular frame 511, and a limiting groove 516 is provided in the middle of the upper and lower ends of the inner wall of the connecting groove 515. The anti-fall mechanism 53 includes an embedded block 531 and a pressure block 532 fixedly installed at the upper and lower ends of the embedded block 531. A long rod 533 is fixedly installed in the middle of one end of the embedded block 531, and a limiting block 534 is fixedly installed on one end of the outer wall of the long rod 533. A rope 535 is fixedly installed at one end of the long rod 533, and a binding belt 536 is fixedly installed at one end of the rope 535. The embedded block 531 is movably installed in the inner cavity of the connecting groove 515, and the pressure block 532 is movably installed in the inner cavity of the limiting groove 516.

[0028] Specifically, when the maintenance personnel inspect the circuit, they first stand in the inner cavity of the rectangular frame 511, and drive the collection frame mechanism 51 to rise to the lower end of the maintenance line by starting the lifting component 3. While the collection frame mechanism 51 rises, the maintenance personnel bind the binding belt 536 to the waist. The binding belt 536 can be any high-altitude work belt normally used on the market. By fixing the rope 535 and the long rod 533 at one end of the binding belt 536, when the maintenance personnel walk on the upper end of the rectangular frame 511, the rope 535 will drive the long rod 533 and the embedded block 531 and the pressure block 532 fixedly installed at one end of the long rod 533 to slide in the inner cavity of the connecting groove 515 and the limiting groove 516. Such an arrangement can provide anti-fall protection for the maintenance personnel through the binding belt 536 without affecting the movement of the maintenance personnel, thereby improving the safety of the maintenance personnel at work.

[0029] Embodiment 2:

[0030] See also Figure 3 The interception mechanism 52 includes a bottom long plate 521 and a round rod 522 fixedly installed at the upper end of the anti-fall mechanism 53 at linear and equidistant intervals. A hollow cylinder 523 is fixedly installed at the upper end of the round rod 522. Sliding grooves 524 are provided on both sides of the upper end of the outer wall of the hollow cylinder 523. The round rod 522 is movably installed in the inner cavity of the penetration groove 513.

[0031] Round blocks 525 are fixedly installed at both ends of the outer wall of the hollow cylinder 523, and insertion rods 526 are movably installed in the inner cavities at both ends of the hollow cylinder 523. A long threaded rod 527 is fixedly installed on one side of the upper end of the insertion rod 526. The long threaded rod 527 is movably installed in the inner cavity of the sliding groove 524, and the long threaded rod 527 is threadedly fixed on one side of the notch of the sliding groove 524 by a nut, and the insertion rod 526 is movably inserted in the inner cavity of the circular groove 514.

[0032] Specifically, before entering the inner cavity of the rectangular frame 511, the operator can press the hollow cylinder 523 down to the middle and lower end of the inner cavity of the inner groove 512. After entering the inner cavity of the rectangular frame 511, the operator can pull the hollow cylinder 523 to drive the round rod 522 and the bottom long plate 521 to rise, so that the upper end of the bottom long plate 521 is pressed against the lower end of the penetration groove 513, and at the same time, the two ends of the outer wall of the hollow cylinder 523 and the circular groove 514 correspond to each other, and the long threaded rod 527 is moved to drive the insertion rod 526 to be inserted into the inner cavity of the circular groove 514, and then the long threaded rod 527 is fixedly installed on one side of the notch of the sliding groove 524 by using a nut to complete the fixation of the insertion position of the insertion rod 526. By designing a lifting and lowering setting for the interception mechanism 52, it is convenient for maintenance personnel to enter and exit the inner cavity of the rectangular frame 511, thereby improving the convenience of use.
