[0002] With the development of the electric power industry, more and more high-voltage and extra-high-voltage power lines are being erected. In the process of line erection, more and more situations of crossing railways, highways, and existing high-voltage lines appear. In order to ensure the safety of the objects being crossed, protective facilities are required when laying lines across the above-mentioned objects. Such facilities are called crossing frames.

[0003] There are many types of crossing frames, such as bamboo strip type, scaffolding type, revolving tower type, telescopic arm type, and tilt arm type. The crossing frame is usually made of insulating materials such as insulating steel pipes, bamboo sticks, and wooden sticks.

In order to facilitate the use of the crossing frame in actual applications, it is necessary to simplify the operation difficulty of the crossing frame to achieve higher precision and better synchronization control; to this end, we provide a modular multi-axis collaborative control crossing frame mechanism to solve the above problems.

DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] As described in the background technology, in order to facilitate the use of the crossing frame in actual applications, it is necessary to simplify the operation difficulty of the crossing frame to achieve higher precision and better synchronization control. To this end, this embodiment provides a modular multi-axis collaborative control crossing frame mechanism.

[0023] See also Figures 1 to 4This embodiment proposes a modular multi-axis collaborative control spanning frame mechanism, including a base 1, an adjustment mechanism 2 is arranged above the base 1, the adjustment mechanism 2 includes a support frame 202 and four servo motors 201, and in the initial state, the support frame 202 is at the lowest point.

[0024] A control system is provided inside the servo motor 201, and a power-off locking device is installed in the control system. When the power is disconnected, the power-off locking device will lock the rotor of the servo motor 201 at the current position to prevent the servo motor 201 from running. When the power is restored, the power-off locking device will be unlocked to allow the servo motor 201 to continue running.

[0025] Four telescopic rods 3 are fixedly connected to the upper surface of the base 1, and each telescopic rod 3 is fixedly connected to the support frame 202. By providing the telescopic rods 3, the movement of the support frame 202 can be limited, making it more stable during the up and down movement.

[0026] Two detachable protective doors 4 are installed on the inner wall of the support frame 202. By setting the protective doors 4, construction workers can be protected and the safety of construction workers when operating in the support frame 202 is improved. The front and back sides of the support frame 202 are fixedly connected with climbing ladders 5. The climbing ladder 5 can be of a retractable type. By setting the climbing ladder 5, construction workers can easily climb into the interior of the support frame 202.

[0027] Each servo motor 201 is fixedly connected to the base 1, and the output shaft end of each servo motor 201 is fixedly connected to a threaded rod 203. Four support blocks 6 are fixedly connected to the upper surface of the base 1, and the four support blocks 6 are rotatably connected to the four threaded rods 203 respectively. By providing the support blocks 6, the threaded rods 203 can be auxiliary supported, thereby improving the stability of the threaded rods 203 during rotation.

[0028] The base 1 provides fixed support for the servo motor 201 . After the servo motor 201 is started, it can drive the threaded rod 203 to rotate forward and reversely. The four servo motors 201 are all electrically connected to the same controller to achieve synchronous control of the movements of the four servo motors 201 .

[0029] The outer surface of each threaded rod 203 is threadedly connected to a screw block 204, each screw block 204 is slidably connected to the base 1, the inner wall of each screw block 204 is hinged to a support rod 205 through a pin, and each support rod 205 is hinged to the support frame 202 through a pin.

[0030] After the threaded rod 203 rotates, it can drive the screw block 204 to slide left and right along the upper surface of the base 1. At this time, the two opposite groups of screw blocks 204 can move closer to and away from each other. After the screw block 204 moves, it can drive the support rod 205 to move. The four support rods 205 jointly provide limited support for the support frame 202.

[0031] One side and the other side of the support frame 202 are both hinged with connecting rods 206 through a pin shaft, and a plurality of insulating hooks 207 are installed on the bottom surface of each connecting rod 206. The upper surface of each connecting rod 206 is hinged with a limiting rod 208 through a pin shaft. One side and the other side of the support frame 202 are fixedly connected with a slot 209, and the limiting rod 208 is adapted to the slot 209.

[0032] After the construction personnel enter the support frame 202, they can control the crossing frame to adjust to a suitable height, and then pull the limit rod 208 to make the end away from the connecting rod 206 snap into the slot 209. At this time, the limit rod 208 drives the connecting rod 206 to rotate to a horizontal position, and then hang the wire on the insulating hook 207 to achieve the crossing effect.

[0033] Four connecting blocks 7 are fixedly connected to the bottom surface of the base 1. Two rotating rods 8 are arranged under the base 1. The connecting blocks 7 are rotatably connected to the rotating rods 8. The outer surface of each rotating rod 8 is fixedly connected to two rotating wheels 9. By arranging the connecting blocks 7, rotating rods 8 and rotating wheels 9, the crossing frame can be easily moved as a whole, thereby improving the convenience of using the crossing frame.

[0034] Four servo electric cylinders 10 are installed on the bottom surface of the base 1 , and a limit block 11 is arranged below the base 1 . The output end of each servo electric cylinder 10 is fixedly connected to the upper surface of the limit block 11 .

[0035] The four servo electric cylinders 10 are electrically connected to the same controller. When the crossing frame moves to a suitable position, the four servo electric cylinders 10 are controlled to start synchronously, and jointly drive the limit block 11 to move downward until it is in close contact with the ground, so as to limit and fix the moved crossing frame. At the same time, the limit block 11 can act as a counterweight block to improve the stability of the crossing frame during use.

[0036] The inner wall of the base 1 is threadedly connected with two screw rods 12 , the bottom end of each screw rod 12 is fixedly connected with a limit plate 13 , and the top end of each screw rod 12 is fixedly connected with a handle 14 .

[0037] Rotating the handle 14 can drive the screw rod 12 to rotate. The screw rod 12 drives the limit plate 13 to move downward until it is closely fitted with the ground under the action of the thread of the base 1, thereby further limiting and fixing the moved crossing frame, and further enhancing the overall stability of the crossing frame.

[0038] Working principle: When using the modular multi-axis collaborative control spanning frame mechanism, first move it to a suitable position, then the construction personnel enter the support frame 202, and control the four servo motors 201 to start synchronously. After the servo motor 201 is started, it can drive the threaded rod 203 to rotate, and the threaded rod 203 drives the screw block 204 to slide along the upper surface of the base 1. At this time, the two groups of screw blocks 204 relative to each other are close to each other, and the two groups of screw blocks 204 respectively drive the two groups of support rods 205 to approach each other. The four support rods 205 jointly lift the support frame 202 and adjust the support frame 202 to a suitable position. After the height is reached, the construction personnel pull the four limit rods 208 in turn, so that the ends of the four limit rods 208 away from the connecting rod 206 are successively inserted into the two slots 209. At this time, the limit rods 208 drive the connecting rod 206 to rotate to a horizontal position, and then the wires are hung on the insulating hooks 207 to achieve the crossing effect. The utility model can control the height of the crossing frame in a multi-axis manner during the actual use of the crossing frame, thereby simplifying the operating difficulty of the crossing frame and making the movement control of the crossing frame more precise and the synchronization better, thereby improving the convenience and stability of the crossing frame when in use.
