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

[0005] The purpose of the present invention is to provide a utility pole erector device to solve the deficiencies in the above-mentioned prior art.

[0006] In order to achieve the above-mentioned objectives, the present invention provides the following technical solutions: a utility pole erecting device, comprising a fixed seat, a rotating seat rotatably connected to the fixed seat, a sliding seat slidably connected to the rotating seat, a first locking member is arranged between the rotating seat and the sliding seat, a cover plate is detachably connected to the sliding seat, an arc-shaped clamping plate is slidably connected to the sliding seat, a second locking member is arranged between the arc-shaped clamping plate and the sliding seat, a plurality of guide wheels are respectively arranged on the sliding seat and the cover plate, when the cover plate is connected to the sliding seat, the arc-shaped groove cooperates with the arc-shaped clamping plate located at the clamping station to clamp the utility pole, the guide wheels are arranged in a circular array along the circumference of the arc-shaped groove to abut against the circumferential side of the utility pole, and when the rotating seat rotates relative to the fixed seat to erect the utility pole, the first locking member and the second locking member are unlocked.

[0007] The cam is fixedly mounted on the second end of the second gear and is adapted to engage with the first end of the second gear when the cam is engaged with the first gear.

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

[0009] Furthermore, the first locking member includes a second rack, the second rack is fixed to the side of the second hook plate away from the first hook plate, a third gear is rotatably installed in the rotating seat, the third gear is meshed with the second rack, a third rack is slidably installed in the rotating seat, the third gear is meshed with the third rack, the third rack is parallel to the second rack and opposite to the rack, an end of the third rack extends out of the rotating seat and is fixed with a latch, and a socket for matching with the latch is provided on a side of the sliding seat facing the latch.

[0014] In the above technical scheme, the present invention provides a pole erecting device for electric poles, which can clamp the electric poles through the arc-shaped clamping plate and the arc surface on the inner side of the cover plate. At the same time, the rotation of the rotating seat can be achieved by pulling a simple cable in terrain that heavy equipment cannot reach, so that the electric pole can reach a vertical state without human support. The axis of the circular array of guide wheels is coaxial with the axis of the arc-shaped clamping plate, so that the electric pole can always be in a vertical state. The cooperation of the guide wheel and the moving mechanism allows the electric pole to stably enter the pre-dug hole.

[0018] 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 described in detail below with reference to the accompanying drawings.

[0019] See also Figure 1-Figure 2 as well as Figure 5-Figure 6 A pole erecting device for a utility pole provided in an embodiment of the present invention comprises 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 comprises a second rack 51, the second rack 51 is fixed to 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 is meshed with the second rack 51, a third rack 53 is slidably installed in the rotating seat 2, the third gear 52 is meshed with the third rack 53, the third rack 53 is parallel to the second rack 51 and opposite to the rack, an end portion of the third rack 53 extends out of the rotating seat 2 and is fixed with a latch 54, and a socket for matching the latch 54 is provided on a side of the sliding seat 3 facing the latch 54.

[0020] In the above technical solution, after the electric pole is placed on the arc clamp 31, the cover plate 4 is installed, the second wedge block 62 and the first wedge block 63 are in a tight state, and then the force is transmitted to the arc clamp 31 through the connecting rod 61. The arc clamp 31 and the inner arc surface of the cover plate 4 clamp the electric pole. During this process, the pin 54 is in a locked state inserted into the socket, so the sliding seat 3 is in a locked state and cannot slide. In the process of the rope pulling up the electric pole, the clamped electric pole will gradually rise with the rotation of the rotating seat 2 and finally reach a vertical state.

[0021] Then the side surface of the fixed seat 1 will contact the end of the second hook plate 65, and make the second hook plate 65 slide along the installation position, and then the second hook plate 65 drives the second rack 51 to move, and the second rack 51 drives the third gear 52 meshing with it to rotate, and then drives the third rack 53 to slide in the opposite direction of the second rack 51, and then drives the latch 54 to leave the socket, 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, and the sliding seat 3 and the cover plate 4 can be driven to move through the force transmitted by the moving mechanism 7.

[0022] See also Figure 1-Figure 2 as well as Figure 4-Figure 6 An arc-shaped clamping plate 31 is slidably connected to the sliding seat 3, and 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, which is slidably installed in the sliding seat 3, and the arc-shaped clamping plate 31 is fixedly connected to the connecting rod 61. A first wedge block 63 is fixed at each end of the connecting rod 61 away 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, and two second wedge blocks 62 are fixed at the end of the first hook plate 64, and the inclined surfaces of each group of opposite second wedge blocks 62 are in sliding contact and abutment with the inclined surfaces of the first wedge blocks 63.

[0023] A second hook plate 65 is slidably installed in the sliding seat 3, and the sliding direction of the second hook plate 65 is parallel to the sliding direction of the arc clamping plate 31. The hook portion of the second hook plate 65 is hooked and locked with the hook portion of the first hook plate 64, and the end of the second hook plate 65 extends through the rotating plate. A wedge-shaped push block 66 is fixed to the side of the second hook plate 65. When the second hook plate 65 slides, the hook portion and the first hook plate 64 are first unhooked, and then the side of the wedge-shaped push block 66 can push the first hook plate 64 to slide along the installation direction. The side of the first hook plate 64 is connected to the rotating seat 2 through a guide rod with a first return spring 67, and the middle of the second hook plate 65 is connected to the rotating plate through a guide rod with a second return spring 68.

[0024] 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.

[0025] 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.

[0026] When the whole device is transported to the working position, the fixed position of the fixed seat 1 is a certain distance away from the pre-dug hole. As the rotating seat 2 rotates to the vertical position of the electric pole, 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 side 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, and the electric pole moves downward under the action of 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.

[0027] The first gear 72 of the present invention is driven by the first gear 73 to rotate, and the second gear 73 drives the meshing first gear 72 to rotate. The first gear 72 of the present invention is driven by the first gear 73 to rotate, and the first gear 72 of the present invention is driven by the second gear 73 to rotate. The first gear 72 of the present invention is driven by the first gear 73 to rotate, and the first gear 72 of the present invention is driven by the meshing first gear 71 to rotate. The rotation of the guide wheel 75 will drive the sliding seat 3, the cover plate 4, the second gear 73, the second sprocket 742, the connecting rod 61, the arc 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 bottom leaves the hole and the lowest point is above the ground plane by a certain distance. At this time, the filling operation can be carried out. After the filling operation is completed, the electric pole is stably fixed, and the overall device can be separated from the electric pole by removing the cover plate 4.

[0028] It is worth mentioning that after the electric pole is pulled to a vertical state, the electric pole will fall slowly under the action of the damping bearing 76, thereby avoiding the vertical deviation of the electric pole caused by an excessively fast falling speed.

[0029] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
