Description

Technical Field

[0001] The present invention relates to the technical field of power systems, and specifically to a repair and straightening device for cement poles. Background Art

[0002] As an important part of the power transmission network, cement poles are widely used in urban, industrial and mining, rural and other areas. However, since they are basically installed in the wild with a complex environment and are affected by various factors, for example, severe weather such as heavy rain and strong wind may exert a powerful external force on the poles, loosening the foundation and causing the poles to tilt. In addition, long-term rain erosion, soil erosion, and changes in geological conditions such as ground settlement and landslides will also affect the stability of the poles and cause them to gradually tilt. The problem of pole tilting is relatively common.

[0003] After the pole tilts, it can generally continue to be used through straightening operations. For example, the patent with publication number CN111021815A discloses a pole straightening device for power engineering construction, including a first bottom plate, a second bottom plate, a pole cast in the soil, and a screw rod. The top of the second bottom plate is fixedly connected with a motor box, the inside of the motor box is provided with a motor, the top of the motor box is fixedly connected with a first fixing plate, the top of the motor box is provided with a first through hole, the output shaft of the motor extends to the top of the first fixing plate at the first through hole, a fixed sleeve is sleeved outside the output shaft of the motor, a plurality of second through holes are opened at the top of the first fixing plate, and rotating rings are provided at the second through holes of the first fixing plate. The present invention drives the screw rod to rotate by setting a motor, so that the screw rod enters the soil, loosening the soil on one side of the pole, making it more convenient and efficient to straighten the pole.

[0004] Another example is the patent with publication number CN109798018A, which discloses a pole straightening device and a straightening method, belonging to the technical field of power maintenance equipment. The present invention includes: a lower connecting seat for connecting with a working surface; a telescopic support rod, one end of which is hinged to the lower connecting seat; a jacking mechanism arranged on the telescopic support rod for changing the length of the telescopic support rod; and an upper connecting seat, which is hinged to the other end of the telescopic support rod and is used for connecting with the pole. When straightening the pole in the present invention, the lower connecting seat is connected to a working surface such as the ground, the upper connecting seat is connected to the pole, and then the jacking mechanism is driven to extend the telescopic support rod to jack the pole, and the pole is straightened by relying on the jacking force. The stress condition is better, which can greatly save manpower and will not cause the pole to sink.

[0005] In the prior art such as the above-mentioned patent, the pole erecting device has the advantages of being more convenient, having higher efficiency, better stress conditions, and being able to greatly save manpower. However, the common deficiency is that during the actual operation process, other tools are needed to measure whether the electric pole has returned to the vertical state, and the device itself lacks a verticality detection system, resulting in that construction workers must rely on external measuring instruments or visual inspection to evaluate the vertical state of the pole body. When in the field without measuring equipment or in a low-illumination working environment, this technical limitation will cause subjective errors in visual judgment. More seriously, the un-detected pole inclination will produce a cumulative effect in the later stage, and the accelerated inclination will make the straightening operation need to be carried out again, thus wasting manpower and material resources. Summary of the Invention

[0030] 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 in conjunction with the drawings.

[0031] Please refer to Figures 1-10 , a cement pole maintenance and straightening device provided by an embodiment of the present invention is used for straightening a cement pole with an inclination angle within 10°, and includes a fixed seat 1 and a mounting frame 2 fixedly connected to each other. It also includes a first arc-shaped push ring 3, which is horizontally slidably connected to the mounting frame 2. A mounting seat 47 is slidably mounted on the mounting frame 2. A locking assembly 49 is arranged on the side of the mounting frame 2. The driving mechanism 4 includes a first rack 41, which is slidably mounted on the mounting frame 2, and its end is fixedly connected to the first arc-shaped push ring 3. A rotating shaft 43 is rotatably mounted on the mounting seat 47. A first gear 431 is fixedly mounted on the rotating shaft 43. The first gear 431 meshes with the first rack 41. The rotating shaft 43 penetrates and extends out of one side of the mounting frame 2 and is fixed with a turntable 46. The diameter of the turntable 46 is larger than the diameter of the first gear 431.

[0032] By rotating the turntable 46, the rotation of the turntable 46 drives the rotation of the axle 44 of the first gear 431. Further, the axle 44 drives the first gear 431 to rotate. The rotation of the first gear 431 drives the first rack 41 to move and drives the first arc-shaped push ring 3 to move. Due to the fact that the diameter of the turntable 46 is larger than the diameter of the first gear 431, under the action of the lever principle, the operator can push the pole to move in the vertical direction with less effort.

[0033] There are two embodiments designed for the second arc-shaped pushing ring 31. In one embodiment, a second rack 42 is slidably mounted on the mounting frame 2, and the second arc-shaped pushing ring 31 is fixedly connected to the second rack 42. A wheel shaft 44 is rotatably mounted on the mounting seat 47, and a second gear 441 is provided on the wheel shaft 44. The second gear 441 meshes with the second rack 42. The first gear 431 is drivingly connected to the second gear 441 through a transmission assembly 45. The transmission assembly 45 includes a synchronous transmission belt 451 and two synchronous belt pulleys 452. The two synchronous belt pulleys 452 are respectively fixedly connected to the wheel shaft 44 and the rotating shaft 43, and the two synchronous belt pulleys 452 are drivingly connected through the synchronous transmission belt 451. A torque limiter 48 is installed between the second gear 441 and the wheel shaft 44. The inner wall of the torque limiter 48 is fixedly connected to the rotating shaft, and its outer wall is fixedly connected to the second gear 441. The arc-shaped portion of the second arc-shaped pushing ring 31 remains in tight contact with the electric pole. The sliding direction of the second arc-shaped pushing ring 31 is the same as that of the first arc-shaped pushing ring 3, and the axis of the second arc-shaped pushing ring 31 is parallel to the axis of the first arc-shaped pushing ring 3.

[0034] In the above technical solution, when the first gear 431 rotates, it drives the second gear 441 to rotate through the synchronous transmission belt 451 as Figure 3 shown. The rotation of the second gear 441 drives the second rack 42 to move and drives the second arc-shaped pushing ring 31 to move. The moving amount of the first arc-shaped pushing ring 3 located above is greater than that of the second arc-shaped pushing ring 31 located below. Under the action of the torque limiter 48, the second gear 441 located below continuously switches between the rotating and stopping states, and thus the second arc-shaped pushing ring 31 and the first arc-shaped pushing ring 3 always fit against the electric pole and push the electric pole to move.

[0035] In another embodiment, as Figure 4 shown, the second arc-shaped pushing ring 31 is fixedly connected to a sliding rod 32. The second arc-shaped pushing ring 31 is horizontally slidably mounted on the mounting frame 2 through an elastic member. The elastic member is used to push the sliding rod to move. The elastic member is a second spring 321. One end of the second spring 321 is fixedly connected to the mounting frame 2, and the other end is fixedly connected to the sliding rod 32. The arc-shaped portion of the second arc-shaped pushing ring 31 remains in tight contact with the electric pole under the action of the elastic member. The sliding direction of the second arc-shaped pushing ring 31 is the same as that of the first arc-shaped pushing ring 3, and the axis of the second arc-shaped pushing ring 31 is parallel to the axis of the first arc-shaped pushing ring 3.

[0036] A telescopic rod, one end of which is rotatably connected to the mounting frame 2, and the other end of the telescopic rod is rotatably connected to a rotating portion 52, wherein the rotating portion 52 has an arc-shaped chamber, a fixed arc plate 51, which is fixedly connected to the rotating portion 52, a movable arc plate 511, which is slidably connected to the rotating portion 52, the axial direction of the movable arc plate 511 is the same as the axial direction of the fixed arc plate 51, and the movable arc plate 511 can be locked on the rotating portion 52 at any position during the sliding process through a locking element, a rotating cylinder 53, which is rotatably connected in the arc chamber, and a positioning rod 54 is axially slidably connected in the rotating cylinder 53, one end of the positioning rod 54 is in sliding contact with the arc bottom wall of the arc chamber, and a positioning hole is provided in the middle of the arc bottom wall.

[0037] In the above technical solution, Figure 3 As shown, since the rotating cylinder 53 is rotatably installed in the U-shaped shell, and a counterweight block 55 is fixed at the lower part of the rotating cylinder 53, the rotating cylinder 53 always maintains a vertical downward state under the action of gravity. At this time, the through hole below the rotating part 52 is not facing the telescopic end of the rotating cylinder 53, so the telescopic end cannot be extended. When the pole is straightened to the vertical state, since the axis of the rotating part 52 is parallel to the axis of the pole, the through hole below the rotating part 52 faces the telescopic end of the rotating cylinder 53. At this time, the telescopic end of the rotating cylinder 53 extends out of the U-shaped shell, and the extension of the telescopic end drives the first magnet block 66 to move downward.

[0038] The locking member 6 includes a third gear 61 and a fourth gear 62 rotatably mounted on the mounting frame 2, the third gear 61 meshes with the fourth gear 62, the third gear 61 has a larger diameter than the fourth gear 62, the fourth gear 62 is transmission-connected to the rotating shaft 43 via a spline, a friction disc 63 is coaxially fixedly mounted on the third gear 61, a locking rod 64 rotatably mounted on the mounting frame 2 is arranged above the friction disc 63, a V-shaped groove is provided at the other end of the locking rod 64, a rubber 65 is fitted and fixed on the inner wall of the V-shaped groove, a chamfer is provided on the edge of the friction disc 63 for use with the V-shaped groove, the locking member 6 also includes a first magnet block 66, the first magnet block 66 is fixed to the end of the positioning rod 54, and can pass through the lower through hole with the positioning rod 54, a second magnet block 67 is fixed to the end of the locking rod 64 close to the through hole, and a counterweight block 55 is fixed to the outer surface of the rotating cylinder 53.

[0039] The telescopic end extends to drive the first magnet block 66 to move downward to the effective adsorption position, and adsorbs the second magnet block 67 through magnetic force. Then, the second magnet block 67 drives the locking rod 64 to rotate along the rotation mounting point until the second magnet block 67 contacts the first magnet block 66. Then, the V-shaped groove at the other end of the locking rod 64 moves downward, and then the rubber 65 contacts and approaches the friction disc 63. Under the action of friction, the friction disc 63 rotates. The friction disc 63 is stressed and fixes the third gear 61 to stop rotating. Since the diameter of the third gear 61 is much larger than that of the fourth gear 62, the fourth gear 62 is locked from rotating under the action of the lever principle. Then, the force is transmitted to the turntable 46 through the spline. After the operator feels the resistance, the turntable 46 can be stopped from rotating. Under the action of the lever principle, the friction force between the rubber 65 and the surface of the friction disc 63 can prevent the pole from moving in the reverse direction.

[0040] The locking assembly 49 includes a connecting plate 491 fixedly installed on the side wall of the mounting frame 2. A limiting plate 492 is fixedly installed on the side wall of the connecting plate 491. A locking tongue 493 is also slidably installed on the side wall of the connecting plate 491. A spring 494 is fixedly installed between the locking tongue 493 and the connecting plate 491. Push the mounting seat 47 until the side wall of the mounting seat 47 abuts against the locking tongue 493 and pushes the locking tongue 493 to slide towards the connecting plate 491. Then, the side wall of the mounting seat 47 contacts the limiting plate 492. At this time, the locking tongue 493 is reset under the elastic potential energy of the spring 494, completing the locking of the lateral movement of the mounting seat 47.

[0041] Working principle: Before operation, the mounting seat 47 is in an unlocked state. At this time, the first rack 41 and the first gear 431, and the second rack 42 and the second gear 441 are not engaged. The operator pushes the device to move through the universal wheels under the fixed seat 1 until the first arc-shaped push ring 3 contacts the inclined pole (the inclination angle of the pole is within 10°). Then, the device is adjusted. Under the action of the pole, the first arc-shaped push ring 3 and the first rack 41 slide until the second arc-shaped push ring 31 contacts the pole. Since the movement directions of the first arc-shaped push ring 3 and the second arc-shaped push ring 31 are the same and their axes are both vertical, after the first arc-shaped push ring 3 and the second arc-shaped push ring 31 are both in close contact with the side wall of the pole, the line connecting the centers of the first arc-shaped push ring 3 and the second arc-shaped push ring 31 is parallel to the axis of the pole. Then, the universal wheels are retracted and the device is fixed to the ground. The fixed arc plate 51 fixed on the rotating part 52 is adjusted until the inner arc surface of the fixed arc plate 51 is in close contact with the pole. Then, the movable arc plate 511 on the other side is slid until it is in close contact with the pole and the movable arc plate 511 is locked. Then, the balancing assembly 5 is in a state of being fixed to the pole. At this time, the axis of the rotating part 52 is consistent with the axis of the pole.

[0042] Push the mounting seat 47 until the side wall of the mounting seat 47 abuts against the locking tongue 493 and push the locking tongue 493 to slide in the direction of the connecting plate 491. Subsequently, the side wall of the mounting seat 47 contacts the limiting plate 492. At this time, the locking tongue 493 is reset under the elastic potential energy of the spring 494, completing the locking of the lateral movement of the mounting seat 47. At this time, the first rack 41 meshes with the first gear 431, and the second rack 42 meshes with the second gear 441. During the movement of the axle 44 of the first gear 431, the fourth gear 62 is not driven to move. The fourth gear 62 is always connected to the axle 44 of the first gear 431 through a spline.

[0043] Rotate the turntable 46. The rotation of the turntable 46 drives the rotation of the axle 44 of the first gear 431. Further, the axle 44 drives the rotation of the first gear 431. While the first gear 431 rotates, it drives the rotation of the second gear 441 through the synchronous transmission belt 451. The rotation of the first gear 431 and the second gear 441 drives the movement of the first rack 41 and the second rack 42, and drives the movement of the first arc-shaped push ring 3 and the second arc-shaped push ring 31. Since the diameter of the turntable 46 is larger than the diameters of the first gear 431 and the second gear 441, the operator can save effort to push the electric pole to move in the vertical direction under the action of the lever principle. The movement amount of the upper first arc-shaped push ring 3 is larger than that of the lower second arc-shaped push ring 31. Under the action of the torque limiter 48, the lower second gear 441 continuously switches between the rotating and stopping states. Further, the second arc-shaped push ring 31, the first arc-shaped push ring 3 and the electric pole always fit against the electric pole and push the electric pole to move. During this process, the fourth gear 62 rotates under the action of the spline force transmission, and drives the third gear 61 meshing with it to rotate. The third gear 61 drives the friction disc 63 to rotate.

[0044] The rotating cylinder 53 is rotatably installed in the U-shaped housing, and a counterweight 55 is fixed to the lower part of the rotating cylinder 53. Therefore, the rotating cylinder 53 always maintains a vertically downward state under the action of gravity. At this time, the through hole below the rotating part 52 is not aligned with the telescopic end of the rotating cylinder 53, so the telescopic end cannot extend. When the electric pole is being righted until it reaches the vertical state, since the axis of the rotating part 52 is parallel to the axis of the electric pole, the through hole below the rotating part 52 is aligned with the telescopic end of the rotating cylinder 53. At this time, the telescopic end of the rotating cylinder 53 extends out of the U-shaped housing. The extension of the telescopic end drives the first magnet block 66 to move downward to the effective adsorption position, and adsorbs the second magnet block 67 through magnetic force. Then, the second magnet block 67 drives the locking rod 64 to rotate along the rotation installation point until the second magnet block 67 contacts the first magnet block 66. Then, the V-shaped groove at the other end of the locking rod 64 moves downward, and then the rubber 65 contacts and approaches the friction disc 63. Under the action of friction, the friction disc 63 rotates. The friction disc 63 is stressed and fixes the third gear 61 to stop rotating. Since the diameter of the third gear 61 is much larger than that of the fourth gear 62, the fourth gear 62 is locked from rotating under the action of the lever principle. Then, the force is transmitted to the turntable 46 through the spline. After the operator feels the resistance, the operator can stop rotating the turntable 46. Under the action of the lever principle, the frictional force between the rubber 65 and the surface of the friction disc 63 can prevent the electric pole from moving in the reverse direction.

[0045] Then the operator can carry out the filling and repair operation. After the electric pole is fixed stably, press down the end of the locking rod 64 with the second magnet block 67, push the telescopic end of the rotating cylinder 53 into the rotating part 52, remove the arc-shaped ear plate, and then release the fixation of the fixed seat 1 on the ground, release the universal wheels and move the device away from the electric pole to complete the repair and righting operation.

[0046] 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 protection of the claims of the present invention.
