[0019] The present invention proposes a protective device for tower group operations under high-voltage lines. The protective device for tower group operations under high-voltage lines can bend the lifting rope 37 of the tower crane 36 so that the lifting rope 37 can move the cargo suspended under the lifting rope 37 to under the high-voltage line 39 while maintaining a safe distance from the high-voltage line 39 to complete the cargo lifting work. Therefore, the tower group operation can be carried out smoothly under the high-voltage line 39, thereby improving the progress and efficiency of the construction work under the high-voltage line 39.

[0020] The following is a detailed description of a protective device for high-voltage line tower operations of the present invention through two embodiments.

[0021] Embodiment 1: Figure 1-Figure 5 As shown, the high-voltage line tower group operation protection device includes a screw 4 and a column 13. The lower end of the screw 4 is transmission-connected to a brake motor 3, and the screw 4 is driven to rotate by the brake motor 3. Furthermore, in order to make the screw 4 rotate smoothly and facilitate the installation and fixation of the high-voltage line tower group operation protection device on the transport vehicle 34, a mounting plate 1 can be added. The brake motor 3 is fixedly connected to the lower surface of the mounting plate 1, and the upper surface of the mounting plate 1 is vertically fixedly installed with a stabilizing cylinder 2. The screw 4 vertically penetrates the stabilizing cylinder 2 and is rotationally connected to the stabilizing cylinder 2. The lower end of the column 13 is fixedly connected to the mounting plate 1.

[0022] In this embodiment, if Figure 1-Figure 5 As shown, a slider 6 and an electromagnetic brake 5 are sleeved on the upper end of the screw rod 4, the slider 6 is located below the electromagnetic brake 5, the slider 6 is threadedly connected to the screw rod 4, the electromagnetic brake 5 can slide up and down along the screw rod 4, the electromagnetic brake 5 can brake the screw rod 4, so that the electromagnetic brake 5 and the screw rod 4 are fixedly connected as a whole.

[0023] In this embodiment, if Figure 5As shown, a plug rod 8 is fixedly installed at the lower end of the electromagnetic brake 5, and the plug rod 8 is vertically slidably plugged and connected to the slider 6. An electric latch 9 is detachably fixedly installed in the slider 6, and the electric latch 9 has a locking rod 10, and the locking rod 10 is plugged and fixedly connected to the plug rod 8. The slider 6 and the electromagnetic brake 5 are fixedly connected as a whole by plugging and fixing the electric latch 9 and the plug rod 8.

[0024] In this embodiment, if Figure 1-Figure 5 As shown, a top plate 12 is fixedly mounted on the upper end of the column 13, and an electromagnet 11 is fixedly mounted on the top plate 12. The electromagnet 11 is located above the electromagnetic brake 5. When the electromagnetic brake 5 does not brake the screw 4, the electromagnet 11 is energized to attract the electromagnetic brake 5 to move up and contact the electromagnet 11. A slide rail 14 is fixedly mounted on the column 13, and the slider 6 is slidably connected to the slide rail 14; Figure 5 As shown, the brake motor 3 is started to drive the screw 4 to rotate and drive the slider 6 to move up along the slide rail 14. When the slider 6 moves to the upper end of the slide rail 14, the lower end of the plug rod 8 is inserted into the slider 6. When the slider 6 continues to move up and separates from the slide rail 14, the electromagnetic brake 5 released by the electromagnet 11 is de-energized and descends to contact the upper surface of the slider 6. At this time, the plug rod 8 is completely inserted into the slider 6, and then the electric latch 9 is actuated to make the locking rod 10 and the plug rod 8 plug and fixedly connected, thereby fixing the slider 6 and the electromagnetic brake 5 together. Then the electromagnetic brake 5 is actuated to clamp the brake screw 4 to realize that the screw 4, the electromagnetic brake 5, and the slider 6 are fixedly connected together. In this way, the rotation of the screw 4 drives the slider 6 to rotate synchronously around the screw 4. When the screw 4 stops rotating after rotating for several integer circles, the electromagnetic brake 5 releases the brake on the screw 4, and the electric latch 9 operates to separate the locking rod 10 from the insertion rod 8. At this time, the electromagnet 11 is energized to attract the electromagnetic brake 5 to move upward and is fixedly connected with the electromagnet 11, and the electromagnetic brake 5 is separated from the slider 6. The insertion rod 8 partially extends out of the slider 6 and partially remains in the slider 6. At this time, the brake motor 3 is controlled to rotate in the opposite direction to drive the screw 4 to rotate in the opposite direction to drive the slider 6 to move downward, so that the slider 6 gradually slides into the slide rail 14 and is completely separated from the insertion rod 8, and then the screw 4 continues to rotate in the opposite direction to drive the slider 6 to slide down and reset.

[0025] In this embodiment, if Figure 1-Figure 5 As shown, the slider 6 is fixedly connected to the cantilever 15, and a mounting hole 7 is provided on the side of the slider 6. One end of the cantilever 15 is inserted into the mounting hole 7 and is detachably fixedly connected to the slider 6. A slide cylinder 16 and a driving device are installed on the cantilever 15. The slide cylinder 16 is slidably connected to the cantilever 15, and the driving device is used to drive the slide cylinder 16 to slide on the cantilever 15 to adjust the position of the slide cylinder 16 on the cantilever 15.

[0026] In this embodiment, the driving device is a linear motor, a hydraulic cylinder, a pneumatic cylinder or other device capable of driving the slide 16 to slide on the cantilever 15, such as Figure 1-Figure 5 The driving device shown includes a pulley 17, a transmission belt 18 and a brake motor 19. The pulley 17 has a pair, which is arranged at both ends of the cantilever 15 and is connected to each other through the transmission belt 18. The brake motor 19 is connected to one of the pulleys 17 for driving the transmission belt 18 to rotate. Figure 4 As shown, a through hole 22 is provided on the slide 16, an upper transmission belt 18 is fixedly connected to the slide 16, and a lower transmission belt 18 passes through the through hole 22 without contacting the slide 16. With this design, after the brake motor 19 drives the pulley 17 to rotate, the transmission belt 18 can pull the slide 16 to slide smoothly on the cantilever 15 to adjust the position of the cantilever 15.

[0027] In this embodiment, if Figure 4 As shown, a rope ring 20 is coaxially rotatably installed on the slide 16, and the cross-section of the rope ring 20 is V-shaped. Snap rings 21 are provided at both axial ends of the rope ring 20. The snap ring 21 is coaxially detachably and fixedly connected to the slide 16. The setting of the snap ring 21 ensures that the rope ring 20 can only rotate on its own and cannot move axially. The V-shaped cross-section of the rope ring 20 enables the lifting rope 37 to be stably wound around the rope ring 20 without being separated from the rope ring 20.

[0028] Embodiment 2: This embodiment is a further improvement made on the basis of embodiment 1.

[0029] In this embodiment, if Figure 6-Figure 8 As shown, an annular box 23 is coaxially rotatably installed on the outer circumferential surface of the slide cylinder 16, and retaining rings 25 are provided at both axial ends of the annular box 23. The retaining rings 25 are coaxially detachably fixedly connected to the slide cylinder 16. This design can prevent the annular box 23 from axially moving and can only rotate on its own.

[0030] In this embodiment, if Figure 8As shown, the annular box 23 is provided with a motor 3 27 and a motor 4 29, the annular box 23 is detachably provided with an annular box cover 24, the motor 3 27 is fixedly connected to the slide 16, and is transmission-connected to the annular box 23, and is used to drive the annular box 23 to rotate, for example, a gear ring 26 is coaxially provided in the annular box 23, the gear ring 26 is fixedly connected to the annular box 23, the motor 3 27 is transmission-connected to the gear ring 26, the annular box 23 is driven to rotate by the motor 3 27, and the outer circumferential surface of the annular box 23 rotates coaxially. The rope ring 20 is installed, and the two sides of the rope ring 20 are symmetrically provided with propellers 31 and a rotating shaft 30, the rotating shaft 30 is connected to the ring box 23 for rotation, one end of the rotating shaft 30 is connected to the propeller 31, and the motor 29 is connected to the rotating shaft 30 for transmission. In this design, the propeller 31 can be driven by the motor 29 to rotate to generate a pulling force, and the pulling force direction is coaxial with the rotating shaft 30. The propeller 31 and the rotating shaft 30 are symmetrically arranged on both sides of the rope ring 20 so that the combined force of the two pulling forces generated by the two propellers 31 and the suspension rope 37 The pressure on the rope ring 20 is on the same vertical plane, which is the symmetry plane of the rope ring 20. With this design, the annular box 23 is driven to rotate by the motor three 27, so that the resultant force of the two pulling forces and the pressure of the rope 37 on the rope ring 20 are equal in magnitude and opposite in direction, thereby eliminating the torque effect of the pressure of the rope 37 on the rope ring 20 on the high-voltage line group tower operation protection device, making the high-voltage line group tower operation protection device more stable and safer to work. When the high-voltage line group tower operation protection device in Example 1 is working, the pressure of the rope 37 on the rope ring 20 will be converted into torque on the entire high-voltage line group tower operation protection device, which may easily cause the cantilever 15 and the screw 4 to bend and deform slightly, affecting the smooth movement of the slide 16 and the slider 6. The most important thing is that it causes the high-voltage line group tower operation protection device to quickly suffer from fatigue corrosion of parts and shorten its service life. In addition, the entire high-voltage line group tower operation protection device is subjected to unbalanced force, and the installation and connection firmness of the mounting plate 1 and the transport vehicle 34 is required to be high. Otherwise, the entire high-voltage line group tower operation protection device is very likely to shake, affecting work safety.

[0031] Further, such as Figure 8 As shown, the same end of the rotating shaft 30 on both sides of the rope ring 20 extends into the annular box 23 and is connected through a bevel gear 33. With this design, the rotating shaft 30 on both sides of the rope ring 20 can be set at an angle, which is conducive to the sling rope 37 passing between the two propellers 31 and winding around the rope ring 20, reducing the risk of contact and collision between the sling rope 37 and the propeller 31.

[0032] In this embodiment, if Figure 8 As shown, a rotation angle sensor 40 is provided in the annular box 23 for detecting the rotation angle of the annular box 23 relative to the slide 16; Figure 3As shown, the slider 6 is provided with a visual camera 41, and the visual camera 41 can capture the video images around the rope ring 20. When the rope 37 is wound around the rope ring 20, the visual camera 41 can capture the extension direction of the rope 37 when it passes through the rope ring 20. In this way, the computer can obtain the pressure direction of the rope 37 on the rope ring 20 according to the extension direction of the rope 37 when it passes through the rope ring 20, and then control the motor 3 27 to drive the annular box 23 to rotate, so that the combined force direction of the two pulling forces is opposite to the pressure direction of the rope 37 on the rope ring 20. Then, the pressure of the lifting rope 37 on the rope ring 20 is calculated according to the gravity of the suspended weight 38, and then the size of each component force and the rotation speed of the propeller 31 are calculated. Finally, the motor 29 is controlled to drive the propeller 31 to rotate at a designed speed so that the combined force of the two pulling forces and the pressure of the lifting rope 37 on the rope ring 20 are equal. The tension generated by the propeller 31 offsets the pressure of the lifting rope 37 on the rope ring 20, thereby preventing the pressure of the lifting rope 37 on the rope ring 20 from generating torque on the high-voltage line tower group operation protection device and affecting the safety of the high-voltage line tower group operation protection device.

[0033] In this embodiment, if Figure 7 and Figure 8 As shown, a threading hole 28 is provided in the slide 16, one end of the threading hole 28 is located on the outer circumferential surface of the slide 16 in the annular box 23, and the other end of the threading hole 28 is located on the end surface of the slide 16. With this design, the wire in the annular box 23 can extend out of the annular box 23 from the threading hole 28 without affecting the rotation of the annular box 23 and the slide 16.

[0034] Furthermore, in order to make the rotating shaft 30 rotate smoothly, as Figure 6-Figure 8 As shown, a shaft cylinder 32 is coaxially sleeved outside the rotating shaft 30, and the shaft cylinder 32 is fixedly connected to the annular box 23, and the rotating shaft 30 and the shaft cylinder 32 are rotatably connected.

[0035] The high-voltage line tower group operation protection device of the first embodiment and the second embodiment can be installed and fixed on the ground or other fixed platforms or racks, and can also be installed and fixed on moving objects, such as Fig. 9 and Fig.10 The transport vehicle 34 shown in the figure has multiple high-voltage line group tower operation protection devices of Example 1 or Example 2 fixedly installed on the transport vehicle 34, so as to realize the protection of group tower operation. One tower crane 36 requires at least two high-voltage line group tower operation protection devices of Example 1 or Example 2 to cooperate with each other to realize the bending of the lifting rope 37 of the tower crane 36, so that the lifting rope 37 can move the cargo suspended under the lifting rope 37 to the underside of the high-voltage line 39 while maintaining a safe distance from the high-voltage line 39 to complete the cargo lifting work.

[0036] Below Fig. 9 and Fig.10Taking the working process of the protective device for high-voltage line tower group operation under embodiment 1 and embodiment 2 as an example, the following is described in detail: Fig.11 As shown, a weight 38 is suspended below the suspension rope 37 of the tower crane 36. The weight 38 needs to be delivered to the ground directly below the high-voltage line 39. Affected by the high-voltage line 39, the suspension rope 37 cannot place the weight 38 on the ground directly below the high-voltage line 39. When the tower crane 36 drives the suspension rope 37 to move to the minimum safe distance near the high-voltage line 39, as shown in FIG. Fig. 9 As shown, the cantilever 15 of one of the high-voltage line tower group operation protection devices is controlled to rotate around its screw rod 4, and at the same time, the position of the slide cylinder 16 on the cantilever 15 is adjusted according to the position of the suspension rope 37, so that the slide cylinder 16 on the cantilever 15 is close to the suspension rope 37, and then the cantilever 15 of the other high-voltage line tower group operation protection device is controlled to rotate around its screw rod 4, and the rotation direction is opposite to the rotation direction of the aforementioned cantilever 15, as shown in FIG. Fig. 9 As shown by the middle arrow, the two cantilevers 15 are not at the same height. Fig.10 and Fig.11 As shown, while the cantilever 15 rotates, the position of the slide 16 on the cantilever 15 is adjusted so that the rope rings 20 on the two cantilever 15 are close to the suspension rope 37 and the suspension rope 37 is wound around the rope rings 20. As the cantilever 15 continues to rotate, the suspension rope 37 is bent, as shown in FIG. Fig.11 As shown, the weight 38 is moved horizontally to the bottom of the high-voltage line 39 by means of the rotation of the other cantilever 15, and then the tower crane 36 is controlled to lower the weight 38 until the weight 38 is placed on the ground. In this process, the rope rings 20 on the two cantilevers 15 are equivalent to fixed pulleys. In the process of the other cantilever 15 rotating to drive the weight 38 to move horizontally, one of the cantilevers 15 remains stationary to prevent the suspension rope 37 from touching the high-voltage line 39. The other cantilever 15 is set lower than one of the cantilever 15, as shown in FIG. Fig.11 As shown, the cantilevers 15 of the two high-voltage line group tower operation protection devices cooperate with each other to complete the placement of the heavy object 38 on the ground directly below the high-voltage line 39; for group tower operations, multiple pairs of high-voltage line group tower operation protection devices can be set; After the lifting of the heavy object 38 is completed, the slider 6 of each high-voltage line tower operation protection device is controlled to descend and reset along the screw rod 4, so that the cantilever 15 is placed on the rod seat 35. The rod seat 35 is fixedly installed on the transport vehicle 34 to support the placement of the cantilever 15, so as to keep the cantilever 15 stable during transportation.

[0037] In this embodiment, the advantage of setting the protection device for the group tower operations under the high-voltage line on the transport vehicle 34 is that the protection device for the group tower operations under the high-voltage line can be driven by the transport vehicle 34 to move to the position where it is needed, thereby meeting the protection needs of the group tower operations at different positions, allowing the group tower operations to be carried out smoothly under the high-voltage line 39, and improving the progress and efficiency of the construction work under the high-voltage line 39.

[0038] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
