Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment, in particular to a pole erecting device for an electric pole. Background Art

[0002] Stable power supply is the basic guarantee for industrial production. Telegraph poles transmit electricity to factories, enterprises and other production sites, providing power for various production equipment, supporting the normal operation of industrial production, and promoting regional economic development. At the same time, compared with underground cables, the cost of installing and maintaining telegraph poles is relatively low. Its installation process is relatively simple, and no large-scale underground excavation is required, which reduces construction costs and damage to the surrounding environment; during maintenance, there is no need to use special underground detection equipment and complex excavation tools, which reduces maintenance costs and time costs. In some remote areas or when natural disasters occur, the communication lines on the telegraph poles can ensure the smooth flow of emergency communications, provide information transmission channels for rescue work, and help to carry out rescue operations in a timely manner and reduce disaster losses.

[0003] Due to the heavy weight of the utility pole, heavy lifting equipment is often required to assist in the installation process. For example, the patent with announcement number CN112412151B discloses a utility pole erection device, which relates to the field of utility pole installation. The mobile mechanism is provided with a hole-drilling mechanism, and the middle part of the upper end of the mobile mechanism is provided with a rotating mechanism, and the rotating mechanism is provided with a lifting mechanism. The utility pole erection device described in the present invention can keep the utility pole absolutely vertical in the off-ground state through the free rotation of the concentric ball on the ball panel. The vertical pole has high quality, is not easy to tilt, is firmly fixed, and has high safety. Through the rotation of the connecting mechanism on the second rotating arm, the clamping shaft can be more conveniently fixed on the fixing mechanism. At the same time, the position of the utility pole can be adjusted under the action of gravity, and the verticality of the utility pole and the ground can be improved. The vertical pole fixes the truss firmly, and the gravity of the utility pole is amplified and applied to the motor by the lever principle through the connecting rod, and the motor is pressed down, which is energy-saving and environmentally friendly. The drill tube is driven by the motor to rotate to drill the utility pole hole. The utility pole hole is small and consumes less energy. The soil is automatically brought out by the drill tube, and the labor intensity is low.

[0004] In the prior art such as the above-mentioned patent, the straightening device has the advantages of reducing the intensity of manual labor and improving construction efficiency. However, the common shortcoming is that for remote areas and areas such as mountains and forests where large equipment cannot enter, the pole erection operation still requires people to pull up the poles with ropes and then manually support the poles to enter the pre-dug holes and fill the holes to complete the operation. On the one hand, manual support of the poles in this process is dangerous. On the other hand, manual support of the poles cannot ensure the vertical state of the poles. If there is a tilt phenomenon, the poles may become skewed or collapse later, which will cause damage to the power equipment. Summary of the invention

When the second hook plate slides, first the hook part is disengaged from the hook with the first hook plate, and then the side surface of the wedge-shaped push block can push the first hook plate to slide along the installation direction.

[0008] Further, a first return spring is connected between the side surface of the first hook plate and the rotating seat through a guide rod, and a second return spring is connected between the middle of the second hook plate and the rotating plate through a guide rod.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0026] Please refer to Figure 1 - Figure 2 and Figure 5 - Figure 6 , a pole erecting device provided by an embodiment of the present invention includes a fixed seat 1, a rotating seat 2 is rotatably connected to the fixed seat 1, a sliding seat 3 is slidably connected to the rotating seat 2, a first locking member 5 is arranged between the rotating seat 2 and the sliding seat 3, a cover plate 4 is detachably connected to the sliding seat 3, the first locking member 5 includes a second rack 51, the second rack 51 is fixed on the side of the second hook plate 65 away from the first hook plate 64, a third gear 52 is rotatably installed in the rotating seat 2, the third gear 52 meshes with the second rack 51, a third rack 53 is slidably installed in the rotating seat 2, the third gear 52 meshes with the third rack 53, the third rack 53 is parallel to the second rack 51 and the teeth are facing each other, and its end extends out of the rotating seat 2 and is fixed with a plug 54, and a jack for cooperating with the plug 54 is provided on the surface of the sliding seat 3 facing the plug 54.

[0027] In the above technical solution, after the electric pole is placed on the arc-shaped clamping plate 31, the cover plate 4 is installed. The second wedge block 62 and the first wedge block 63 are in a tightly abutted state. Then, the force is transmitted to the arc-shaped clamping plate 31 through the connecting rod 61. The arc-shaped clamping plate 31 and the inner arc surface of the cover plate 4 clamp the electric pole. During this process, the bolt 54 is in a locked state inserted into the jack. Therefore, the sliding seat 3 is in a locked state and cannot slide. When the rope pulls up the electric pole, the clamped electric pole will gradually rise with the rotation of the rotating seat 2 and finally reach the vertical state.

[0028] Then, the side of the fixed seat 1 will contact the end of the second hook plate 65 and cause the second hook plate 65 to slide along the installation position. Further, the second hook plate 65 drives the second rack 51 to move. The second rack 51 drives the third gear 52 meshing with it to rotate. Then, it drives the third rack 53 to slide in the direction opposite to that of the second rack 51. Further, it drives the bolt 54 to leave the jack, releasing the locking state of the first locking member 5. At this time, the sliding seat 3 is in a slidable state on the rotating seat 2. Through the force transmission of the moving mechanism 7, the sliding seat 3 and the cover plate 4 can be driven to move.

[0029] Please refer to Figure 1 - Figure 2 and Figure 4 - Figure 6 , an arc-shaped clamping plate 31 is slidably connected to the sliding seat 3. A second locking member 6 is arranged between the arc-shaped clamping plate 31 and the sliding seat 3. The second locking member 6 includes a connecting rod 61. The connecting rod 61 is slidably installed in the sliding seat 3. The arc-shaped clamping plate 31 is fixedly connected to the connecting rod 61. Two first wedge blocks 63 are respectively fixed at both ends of the connecting rod 61 far from the arc-shaped clamping plate 31. A first hook plate 64 is slidably installed in the rotating seat 2 along the length direction of the first rack 71. Two second wedge blocks 62 are fixed at the end of the first hook plate 64. The inclined surfaces of each pair of opposite second wedge blocks 62 are in sliding contact and abutting cooperation with the inclined surfaces of the first wedge blocks 63.

[0030] A second hook plate 65 is slidably installed in the sliding seat 3. The sliding direction of the second hook plate 65 is parallel to the sliding direction of the arc-shaped clamping plate 31. The hook part of the second hook plate 65 is hooked with the hook part of the first hook plate 64. The end of the second hook plate 65 penetrates and extends out of the rotating plate. A wedge-shaped push block 66 is fixed on the side of the second hook plate 65. When the second hook plate 65 slides, first, the hook part is unhooked from the first hook plate 64. Then, the side of the wedge-shaped push block 66 can push the first hook plate 64 to slide along the installation direction. A first return spring 67 is connected between the side of the first hook plate 64 and the rotating seat 2 through a guide rod. A second return spring 68 is connected between the middle of the second hook plate 65 and the rotating plate through a guide rod.

[0031] When the first locking member 5 is in an unlocked state, the second wedge block 62 and the first wedge block 63 are pressed against each other and cannot slide relative to each other. When the electric pole is straightened, the first locking member 5 is unlocked, and at the same time, the second hook plate 65 moves to release the hook lock with the first hook plate 64, and the wedge-shaped push block 66 pushes the first hook plate 64 to slide along the installation direction, and then the first hook plate 64 drives the second wedge block 62 to move, and the second wedge block 62 and the first wedge block 63 are separated along the inclined surface, and the second locking member 6 is unlocked. At this time, the first wedge block 63 and the connecting rod are in a state of being locked. 61 is in a free sliding state, and the arc-shaped clamping plate 31 and the inner arc surface of the cover plate 4 no longer clamp the electric pole, and the arc-shaped clamping plate 31 can slide to the side and contact the side of the sliding seat 3, and the electric pole can move downward under the action of its own gravity, and then the bottom of the electric pole is embedded in the pre-dug hole. In this process, the arc-shaped clamping plate 31 and the inner arc surface of the cover plate 4 release the tightness on the electric pole, but due to the limiting effect of the side of the sliding seat 3, the sliding stroke of the arc-shaped clamping plate 31 is slight, and the electric pole can move downward without tilting left or right.

[0032] See also Figure 1 - Figure 3 as well as Figure 7 , a plurality of guide wheels 75 are respectively provided on the sliding seat 3 and the cover plate 4. When the cover plate 4 is connected to the sliding seat 3, the arc groove cooperates with the arc clamping plate 31 located at the clamping station to clamp the electric pole. The guide wheels 75 are arranged in a circular array along the circumference of the arc groove to abut against the circumference of the electric pole. The moving mechanism 7 also includes a first rack 71 fixed on the upper surface of the rotating seat 2. The sliding seat 3 is rotatably connected with a first gear 72 and a second gear 73. The first gear 72 is meshed with the first rack 71 and the first gear 72 is meshed with the second gear 73. One of the guide wheels 75 is meshed with the second gear 73. The transmission connection is through the transmission component 74, and the transmission component 74 includes a first sprocket 741 and a second sprocket 742. The first sprocket 741 is coaxially fixed with one of the guide wheels 75, and the second sprocket 742 is coaxially fixed with the second gear 73. The first sprocket 741 and the second sprocket 742 are connected through chain transmission. For the guide wheel 75 set on the sliding seat 3, a spring telescopic rod 8 is set between its wheel axle and the sliding seat 3. One end of the spring telescopic rod 8 is fixedly connected to the sliding seat 3 through a support rod, and the other end is rotatably connected to the wheel axle through a damping bearing 76. The contact surface between the guide wheel 75 and the electric pole is made of anti-slip material.

[0033] When the overall device is transported to the working position, the fixed seat 1 is fixed at a certain distance from the pre-dug hole. As the rotating seat 2 rotates to the position where the electric pole is vertical, the guide wheel 75 and the spring telescopic rod 8 both enter the hole. At this time, the side of the rotating seat 2 closer to the ground contacts the ground, and the sides of the sliding seat 3 and the cover plate 4 closer to the ground are stuck on the edge of the hole. Therefore, in this state, even if the electric pole falls into the hole, the filling operation cannot be completed. When the electric pole is pulled to the vertical state, the first locking member 5 and the second locking member 6 are in the unlocked state. The electric pole moves downward under its own gravity. Due to the elastic force of the spring telescopic rod 8, the guide wheel 75 can be pressed against the electric pole.

[0034] During the downward movement of the electric pole, rolling friction is generated between the electric pole and the surface of the guide wheel 75, which in turn drives the guide wheel 75 to rotate. The rotation of the guide wheel 75 drives the first sprocket 741 to rotate. The first sprocket 741 drives the second sprocket 742 to rotate through the transmission of the chain. The second sprocket 742 drives the second gear 73 to rotate. The second gear 73 drives the meshing first gear 72 to rotate. Under the meshing action of the first gear 72 and the first rack 71, the rotation will drive the sliding seat 3, the cover plate 4, the second gear 73, the second sprocket 742, the connecting rod 61, the arc-shaped clamping plate 31, the first sprocket 741, the spring telescopic rod 8, and the guide wheel 75 to move upward. After the electric pole completely falls into the hole, the guide wheel 75 at the lowest position leaves the hole and its lowest point is higher than the ground plane by a certain distance. At this time, the filling operation can be carried out. After the filling operation is completed and the electric pole is stably fixed, by removing the cover plate 4, the overall device can be separated from the electric pole.

[0035] It is worth mentioning that after the electric pole is pulled to the vertical state, under the action of the damping bearing 76, the falling action of the electric pole will proceed slowly to avoid the vertical deviation of the electric pole caused by the too fast falling speed.

[0036] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
