Description
Technical Field
[0001] The utility model relates to the technical field of pole erection, in particular to an auxiliary guiding frame for pole erection. Background Art
[0002] Pole erection refers to the process of erecting and fixing poles at predetermined positions, which is one of the important links in the construction of power infrastructure.
[0003] Currently, after selecting a suitable location for erecting poles, equipment such as cranes and hoists are usually used to lift the poles. During the lifting process, 3 to 4 adjustment ropes (also called control ropes) and release ropes are temporarily tied to the poles for straightening the poles. However, during the lifting process, the lower end of the pole contacts the ground, making it difficult to guide the lower end of the pole, and it is easy for the position of the pole to shift during movement, thus affecting the efficiency of pole erection.
[0004] Therefore, in view of the above problems, an auxiliary guiding frame for pole erection has been developed, which can guide the lower end of the pole, avoid the position of the pole from shifting, and ensure the efficiency of pole erection. Content of the Utility Model
[0005] In order to overcome the drawbacks that it is difficult to guide the lower end of the pole in the prior art, and it is easy for the position of the pole to shift during movement, affecting the efficiency of pole erection, the utility model provides an auxiliary guiding frame for pole erection, which can guide the lower end of the pole, avoid the position of the pole from shifting, and ensure the efficiency of pole erection.
[0006] The technical solution of the utility model is: an auxiliary guiding frame for pole erection, including a bottom plate, track wheels, a rotating plate, guiding frames and a pressing member. A plurality of track wheels are rotatably connected to the lower side of the bottom plate, and a rotating plate is rotatably connected to the right part of the bottom plate. Guiding frames are connected to the right sides of the front and rear parts of the rotating plate, and a pressing member is slidably connected between the guiding frames. Lay tracks at the location of erecting the pole, make the track wheels located on the tracks, the rotating plate is initially in a horizontal state, then make the lower end of the pole located between the pressing member and the rotating plate, and limit the lower end of the pole through the pressing member.
[0007] Furthermore, it further includes a first hydraulic cylinder. The front and rear symmetry of the lower right side of the rotating plate is connected with a first hydraulic cylinder, and the telescopic ends of the first hydraulic cylinders are all connected with the pressing member. Under the guiding action of the guiding frames, the telescopic ends of the first hydraulic cylinders drive the pressing member to move towards the direction of the approaching rotating plate, thereby improving the pressing effect of the pressing member on the lower end of the pole.
[0008] Furthermore, it further includes a supporting member. The right side of the upper part of the rotating plate is connected with a supporting member, and the pole is supported and limited through the supporting member.
[0009] Furthermore, the support member is an arc-shaped structure.
[0010] Furthermore, it further includes a second hydraulic cylinder and a support block. The left part of the bottom plate is connected to the second hydraulic cylinder, and the telescopic end of the second hydraulic cylinder is connected to the support block. During the process of the rotating plate rotating from the horizontal state to the vertical state, the support block is gradually driven to move to the right by the telescopic end of the second hydraulic cylinder, so that the support block is always in contact with the rotating plate, thereby supporting the rotating plate through the support block.
[0011] Furthermore, it further includes a limiting cylinder, a limiting block, a sliding column and a spring. The front and rear parts of the bottom plate are both connected to the limiting cylinder, and a plurality of limiting blocks are connected to the inner walls of the limiting cylinders. The front and rear parts of the rotating plate are both connected with a plurality of sliding columns through springs, and the sliding columns are all slidably connected to the rotating plate. When the crane lifts the electric pole, the electric pole rotates gradually from the horizontal state to the vertical state, thereby driving the rotating plate to rotate gradually from the horizontal state to the vertical state. When the rotation speed of the rotating plate reaches a certain speed, the inertial force will overcome the restoring force of the spring, causing the sliding column to slide outwards and be alternately clamped with the limiting block, and the limiting block limits the sliding column, thereby restricting the further rotation of the rotating plate.
[0012] The beneficial effects of the present utility model are as follows: 1. The present utility model drives the pressing member to press and limit the lower end of the electric pole through the telescopic end of the first hydraulic cylinder, and then guides the track wheels and the bottom plate through the preset track, so as to achieve the effect of guiding the lower end of the electric pole, avoiding the deviation of the position of the electric pole, and ensuring the erection efficiency of the electric pole.
[0013] 2. When the rotation speed of the rotating plate of the present utility model is too high, the inertial force overcomes the restoring force of the spring, causing the sliding column to slide outwards and be alternately clamped with the limiting block, and the limiting block limits the sliding column, thereby restricting the further rotation of the rotating plate, so as to achieve the effect of avoiding the electric pole rotating too fast and getting out of control, and reducing the risk of injury to construction workers.

Detailed implementation manners
[0019] The following is only the preferred embodiment of the present invention and does not limit the protection scope of the present invention accordingly.
[0020] An auxiliary guiding frame for erecting a utility pole, as Figures 1-4 shown, includes a bottom plate 1, track wheels 2, a rotating plate 3, a guide frame 4 and a pressing member 5. Four track wheels 2 are rotatably connected to the lower side of the bottom plate 1. A rotating plate 3 is rotatably connected to the right part of the bottom plate 1. Guide frames 4 are connected to the right sides of the front and rear parts of the rotating plate 3. A pressing member 5 is slidably connected between the guide frames 4. Tracks are laid at the location where the utility pole is to be erected, so that the track wheels 2 are located on the tracks. The rotating plate 3 is initially in a horizontal state. Then, the lower end of the utility pole is located between the pressing member 5 and the rotating plate 3, and the lower end of the utility pole is limited by the pressing member 5;
[0021] It further includes a first hydraulic cylinder 6. The first hydraulic cylinders 6 are symmetrically connected to the right sides of the front and rear parts of the lower part of the rotating plate 3. The telescopic ends of the first hydraulic cylinders 6 are both connected to the pressing member 5. Under the guiding action of the guide frames 4, the telescopic ends of the first hydraulic cylinders 6 drive the pressing member 5 to move towards the rotating plate 3, so as to improve the pressing effect of the pressing member 5 on the lower end of the utility pole;
[0022] It further includes a support member 7. The support member 7 is connected to the right side of the upper part of the rotating plate 3, and the utility pole is supported and limited by the support member 7;
[0023] It further includes a second hydraulic cylinder 8 and a support block 9. The second hydraulic cylinder 8 is connected to the left part of the bottom plate 1. The support block 9 is connected to the telescopic end of the second hydraulic cylinder 8. During the process of the rotating plate 3 rotating from the horizontal state to the vertical state, the telescopic end of the second hydraulic cylinder 8 drives the support block 9 to gradually move to the right, so that the support block 9 is always in contact with the rotating plate 3, thereby supporting the rotating plate 3 through the support block 9;
[0024] It also includes a limiting cylinder 10, a limiting block 11, a sliding column 12 and a spring 13. The front and rear parts of the bottom plate 1 are both connected with the limiting cylinder 10, and fourteen limiting blocks 11 are connected to the inner walls of the limiting cylinders 10. Fourteen sliding columns 12 are connected to the front and rear parts of the rotating plate 3 through springs 13 respectively. The sliding columns 12 are all slidably connected to the rotating plate 3. When the crane lifts the electric pole, the electric pole rotates gradually from the horizontal state to the vertical state, thus driving the rotating plate 3 to rotate gradually from the horizontal state to the vertical state. When the rotation speed of the rotating plate 3 reaches a certain speed, the inertial force will overcome the restoring force of the spring 13, causing the sliding column 12 to slide outwards and be staggeredly clamped with the limiting block 11, and the limiting block 11 limits the sliding column 12, thereby restricting the further rotation of the rotating plate 3.
[0025] When the utility model is in use, first, it is necessary to lay a track at the location where the electric pole is to be erected. Then, place the utility model in the operation area so that the track wheels 2 are located on the track. The rotating plate 3 is initially in a horizontal state. Then, place the lower end of the electric pole between the pressing member 5 and the rotating plate 3, and support and limit the electric pole through the support member 7. Next, under the guiding action of the guiding frame 4, drive the pressing member 5 to move towards the rotating plate 3 by the telescopic end of the first hydraulic cylinder 6, so as to press and limit the lower end of the electric pole through the pressing member 5. When the crane lifts the electric pole, it can make the electric pole rotate gradually from the horizontal state to the vertical state, thus driving the rotating plate 3 to rotate gradually from the horizontal state to the vertical state. And during the erection process, the track wheels 2 and the bottom plate 1 are guided through the preset track, so as to guide the lower end of the electric pole. During the process of the rotating plate 3 rotating from the horizontal state to the vertical state, drive the support block 9 to gradually move to the right by the telescopic end of the second hydraulic cylinder 8, so that the support block 9 is always in contact with the rotating plate 3, thereby supporting the rotating plate 3 through the support block 9. When the rotating plate 3 rotates slowly, due to the low rotation speed, the inertial force between the sliding column 12 and the rotating plate 3 is not enough to overcome the restoring force of the spring 13. At this time, the sliding column 12 remains in the initial position and will not slide outwards, and the distance between the limiting block 11 and the sliding column 12 is sufficient and the limiting effect will not be triggered. When the rotating plate 3 rotates at a high speed, the inertial force between the sliding column 12 and the rotating plate 3 increases. At this time, the inertial force is sufficient to overcome the restoring force of the spring 13, causing the sliding column 12 to slide outwards and touch the limiting block 11, and be staggeredly clamped with the limiting block 11. The limiting block 11 limits the sliding column 12, thereby restricting the further rotation of the rotating plate 3. When the speed of the rotating plate 3 slows down to a certain extent and the inertial force is not enough to overcome the restoring force of the spring 13, the spring 13 pulls the sliding column 12 back to the initial position to release the limit, so as to avoid the electric pole rotating too fast and getting out of control, and reduce the risk of construction workers being injured.
[0026] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
