[0020] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] like Figure 1-Figure 7 As shown, an electric construction crane comprises a self-moving crawler trailer, a mounting seat 2 is installed in the middle of the self-moving crawler trailer, a main support cylinder 3 is hingedly connected to the upper and rear parts of the mounting seat 2, a flip mechanism is installed together with the main support cylinder 3 and the mounting seat 2, the upper part of the main support cylinder 3 is a disconnected opening shape, and the left and right parts are respectively fixed with radial and horizontal No. 1 electric push rod 5 and No. 2 electric push rod 6, the push rods of the two No. 2 electric push rods 6 are respectively hinged with support frames 7 horizontally, the front parts of the two support frames 7 are respectively connected to the push rods of the two No. 1 electric push rods 5 in a forward and backward sliding manner, the two support frames 7 are connected to a plurality of vertical No. 1 support shafts 8 that rotate in sequence from front to back, and the front parts are respectively fixed with No. 1 servo motors in the forward and backward directions. 9, the rotating shaft of the No. 1 servo motor 9 is rotatably connected to the support frame 7, and a worm 10 is coaxially fixed thereto, a worm wheel 11 is coaxially fixed to the middle part of each of the No. 1 support shafts 8, and a roller 12 is coaxially fixed to the upper and lower parts, the outer diameter of the worm wheel 11 is smaller than the outer diameter of the roller 12, and is meshed with the worm 10, a plurality of No. 3 electric push rods 13 are fixed to the bottom of the main support cylinder 3, the push rod ends of the No. 3 electric push rods 13 are rotatably connected to support wheels 14, a main electric control system 15 is fixed to the mounting seat 2, a battery and a radio transmission module are electrically connected to the main electric control system 15, and the main electric control system 15 is electrically connected to the No. 1 electric push rod 5, the No. 2 electric push rod 6, the No. 3 electric push rod 13 and the No. 1 servo motor 9.
[0022] When in use, the turning mechanism is controlled to move so that the main support cylinder 3 tilts downward and backward, and then the top of the target electric pole A is lifted to make it gradually parallel to the main support cylinder 3, and then the self-moving crawler trailer is controlled to move backward so that the main support cylinder 3 is coaxial with the electric pole A, and then the No. 3 electric push rod 13 is controlled to extend the push rod appropriately, and the electric pole A is lifted by the supporting wheel 14, and then the No. 1 electric push rod 5 and the No. 2 electric push rod 6 are controlled to extend appropriately, so that the rollers 12 corresponding to the two support frames 7 are aligned with the electric pole A. The left and right parts are clamped together, and then the flip mechanism is controlled to move (supporting the bottom of the pole A during this period), so that the main support tube 3 is slightly tilted forward and downward, and the No. 1 servo motor 9 is controlled to rotate, so that the roller 12 is rotated by the meshing of the worm 10 and the worm wheel 11 to transport the pole A forward. During the transportation, the No. 1 electric push rod 5, the No. 2 electric push rod 6 and the No. 3 electric push rod 13 are controlled to shrink appropriately (that is, when the taper of the pole A is inconvenient, the rotation of the No. 1 servo motor 9 and the No. 1 electric push rod 5, There is a certain mathematical relationship between the contraction of the No. 2 electric push rod 6 and the No. 3 electric push rod 13. Through this mathematical relationship, it is more convenient to use the electric control system to automatically control the contraction of the No. 1 electric push rod 5, the No. 2 electric push rod 6 and the No. 3 electric push rod 13), which can ensure that the electric pole A moves forward normally. When it moves to a suitable position (that is, when the center of gravity of the electric pole A is in the main support tube 3), it stops, and then the electric pole A can be transported on the mountain by a self-propelled crawler trailer (during this period, the head of the electric pole A is facing the mountain slope). ), when it is necessary to bury the electric pole A, the main support tube 3 is flipped backward by controlling the action of the flipping mechanism, so that the electric pole A can slide backward and downward and fall into the pre-dug pit. The main support tube 3 continues to flip backward until the main support tube 3 remains vertical, and the electric pole A can be supported to be vertical. Then, the retraction push rods of the No. 1 electric push rod 5, the No. 2 electric push rod 6 and the No. 3 electric push rod 13 are controlled, and then the self-moving crawler trailer is controlled to move away, so that the electric pole A can be detached from the opening of the main support tube 3.
[0023] A dragging assembly is built into the gap between the two support frames 7, and the dragging assembly includes an inner support tube 17, a bottom tube 18, an outer support tube, a half support tube 20, a tamping half disk 21, a connecting bolt 22, and a rack 23. The rear part of the inner support tube 17 is coaxially threadedly connected to the bottom tube 18, and the inner wall of the inner support tube 17 is a conical surface with a small inner diameter at the front and a large inner diameter at the rear, and the inner wall fits the target concrete electric pole A. The inner support tube 17 and the bottom tube 18 are both made of metal. The inner support tube 17 is coaxially slidably connected to the outer support tube, and the outer support tube is composed of left and right half support tubes 20 spliced together, and the two half support tubes 20 are spliced together by screws. The bolts and nuts are tightened to maintain the splicing, and the rear part is respectively fixed with a tamped half disk 21 that can be spliced into a complete disc shape. A plurality of connecting bolts 22 are inserted into the gap of the outer support tube, and each of the connecting bolts 22 is threadedly connected to the inner support tube 17. The outer wall of the outer support tube is a straight cylindrical shape, and two racks 23 parallel to its axial direction are fixed on the left and right parts. A No. 1 gear 24 is coaxially fixed to the upper and lower parts of the No. 1 support shaft 8, and the No. 1 gear 24 can mesh with the rack 23. The two No. 1 gears 24 on the No. 1 support shaft 8 are located between the two rollers 12, and the outer diameter of the No. 1 gear 24 is smaller than the outer diameter of the roller 12.
[0024] Furthermore, the use of the drag assembly can make it possible to move the utility pole A more smoothly. When using the drag assembly, first insert the inner support tube 17 from the bottom of the utility pole A so that it fits the outer wall of the utility pole A, and then thread the bottom tube 18. At this time, the inner support tube 17 and the bottom tube 18 are fastened to the bottom of the utility pole A. Subsequently, the outer support tube is installed with the inner support tube 17 and connected with the connecting bolt 22. When transporting the utility pole A, by controlling the No. 1 electric push rod 5 and the No. 2 electric push rod 6 to extend, the gears can be moved toward the rack 23 and meshed with each other. At this time, by controlling the No. 1 servo motor 9 to rotate forward and reverse, the utility pole A can be conveniently controlled to move forward and backward compared to the main support tube 3 to change the position of its center of gravity compared to the main support tube 3. When burying the utility pole A, the meshing of the No. 1 gear 24 and the rack 23 can be used. The combination allows the electric pole A and the dragging assembly to be slowly lowered into the pit to reduce the damage to the inner wall of the pit caused by the tilted lowering of the electric pole A. After the lowering is completed, the connecting bolt 22 is removed, and then the No. 1 servo motor 9 is controlled to rotate back and forth, and the meshing of the rack 23 and the No. 1 gear 24 can be used to make the outer support tube move back and forth up and down. When the outer support tube moves upward to a certain position, the backfill is placed in the pit, and the tamping half plate 21 that is subsequently moved down can be used to tamp the backfill, which is convenient for the burying of the electric pole A. After the burying is completed, the bolts and nuts connecting the two half support tubes 20 are removed, which can facilitate the separation of the outer support tube from the electric pole A, and the connecting bolt 22 is used again to cooperate with the inner support tube 17 to fasten the ground wire here, which is convenient for grounding the circuit on the upper part of the electric pole A, saving the trouble of grounding construction again.
[0025] The main support tube 3 is coaxially connected to the auxiliary support tube 25 for rotation. An incomplete outer gear ring 26 is coaxially fixed on the outer wall of the auxiliary support tube 25, and the upper part is a disconnected opening shape. A radial support seat 27 is fixed to the left part of the main support tube 3. A No. 2 servo motor 28 is fixed to the rear end of the support seat 27. The No. 2 servo motor 28 has a braking function. A No. 2 gear 29 is coaxially fixed to the rotating shaft of the No. 2 servo motor 28, and the No. 2 gear 29 is meshed with the outer gear ring 26. A No. 4 electric push rod 30 is fixed to the left front and left rear of the auxiliary support tube 25, and the push rod ends of the two No. 4 electric push rods 30 are also respectively fixed with supporting wheels 14. The No. 4 electric push rod 30 is electrically connected to the main electronic control system 15. Two No. 3 electric push rods 13 are fixed to the front and rear parts of the main support tube 3, and the two No. 3 electric push rods 13 at the front of the main support tube 3 and the two No. 3 electric push rods 13 at the rear are all gathered.
[0026] Furthermore, before burying the electric pole A, by controlling the No. 2 servo motor 28 to rotate, the meshing of the No. 2 gear 29 and the outer gear ring 26 can be used to rotate the auxiliary support tube 25, so that the auxiliary support tube 25 blocks the opening of the main support tube 3, and at the same time makes the No. 3 electric push rod 13 and the No. 4 electric push rod 30 in a "pin" shape, and then the No. 3 electric push rod 13 and the No. 4 electric push rod 30 are controlled to extend the push rods, and the support wheel 14 can be used to clamp the electric pole A in a "pin" shape, so that when the electric pole A is buried, the vertical electric pole A can be supported more stably.
[0027] The mounting seat 2 is plugged into the self-propelled crawler trailer up and down, and the left and right parts of the outer wall of the main support tube 3 are each fixed with an insertion strip 31 extending along the front and rear direction. The opening of the main support tube 3 is plugged with two insertion plates 32 backward through the insertion strip 31, and the two insertion plates 32 are jointly fixed with a storage slot 33. The self-propelled crawler trailer includes a frame 34, and the frame 34 is equipped with a secondary electric control system 35. Another battery and a radio transmission module are also electrically connected to the secondary electric control system 35.
[0028] Furthermore, after the electric pole A is buried and the outer support cylinder is removed, the supporting wheel 14 is used to clamp the electric pole A in a herringbone shape, and then the No. 1 servo motor 9 is controlled to rotate. During this period, the No. 1 electric push rod 5, the No. 2 electric push rod 6, the No. 3 electric push rod 13 and the No. 4 electric push rod 30 are controlled to be appropriately extended and retracted to allow the roller 12 to move up and down along the electric pole A. Then, the tools or items to be transported are placed in the storage slot 33, and the tools or items can be transported up and down along the electric pole A, which is convenient for the circuit maintenance personnel located on the upper part of the electric pole A to take them, reducing the trouble of the maintenance personnel frequently going up and down the electric pole A and the inconvenience of carrying tools or items.
[0029] A vertical No. 5 electric push rod 36 is fixed to the front and rear parts of the frame 34, and a vertical ground plug 37 is fixed to the bottom end of each No. 5 electric push rod 36. A lifting ear 38 is fixed to the outer wall of the main support tube 3. A support 39 is fixed to the front part of the frame 34. The support 39 is rotatably connected to a winch drum 40 and is fixed with a brake motor 41. The rotating shaft of the brake motor 41 is coaxially fixed with the winch drum 40. The winch drum 40 and the lifting ear 38 are jointly fixedly connected with a surplus cable 42. The No. 5 electric push rod 36, the brake motor 41 and the auxiliary electronic control system 35 are electrically connected.
[0030] Furthermore, when the maintenance personnel are working at the top of the electric pole A, the main support cylinder 3 and the auxiliary support cylinder 25 can be moved upward along the electric pole A by rotating the roller 12 and clamping the electric pole A with the supporting wheel 14, and then the self-moving crawler trailer is controlled to move to the opposite direction of the maintenance personnel, and the brake motor 41 is controlled to rotate so that the winch drum 40 rotates to pull the cable 42, thereby applying forces in two directions to the electric pole A (i.e., the inclination of the electric pole A caused by the gravity of the maintenance personnel and the inclination of the electric pole A caused by the pulling of the winch drum 40). The utility pole A is tilted), so as to balance the tilt of the utility pole A and ensure the stability of the position of the utility pole A. During this period, the No. 5 electric push rod 36 is controlled to extend the push rod so that the ground plug 37 is inserted into the ground, which can ensure the stability of the position of the frame 34 relative to the ground, so as to ensure the stability of the pulling of the cable 42 on the utility pole A. After the construction is completed, the main support cylinder 3 and the auxiliary support cylinder 25 are controlled to fall back, and the automatic crawler 47 trailer is controlled to approach, so that the mounting seat 2 is reset and restored, and then the main support cylinder 3 and the auxiliary support cylinder 25 are separated from the utility pole A.
[0031] The left front and right front parts of the frame 34 are respectively fixed with gear reducers 43, and two of the gear reducers 43 are respectively fixed with three servo motors 44, and the rotating shafts of the two three servo motors 44 are respectively fixed coaxially with the input shafts of the two gear reducers 43, and the output shafts of the two gear reducers 43 are respectively coaxially fixed with front track wheels 45, and the front track wheels 45 are horizontally arranged in the left and right directions. The left rear and right rear parts of the frame 34 are respectively connected to rear track wheels 46 that rotate in the left and right directions, and the front track wheels 45 and the rear track wheels 46 are meshed with tracks 47. The left front and right front parts of the frame 34 are respectively hinged with front support arms 48 up and down, and the left rear and right rear parts of the frame 34 are respectively connected to the rear track wheels 46. The right rear part is hinged with a rear support arm 49 up and down, the front parts of the two front support arms 48 are respectively provided with a front grip wheel 50 that rotates along the left and right directions, the rear parts of the two rear support arms 49 are respectively connected with a rear grip wheel 51 that rotates along the left and right directions, and the rear parts of the two rear support arms 49 are respectively fixed with a No. 2 reduction motor 52, and the rotating shafts of the two No. 2 reduction motors 52 are respectively fixed on the same axis as the two rear grip wheels 51, and the front and rear parts of the frame 34 are respectively hinged with two No. 6 electric push rods 53, and the push rods of each No. 6 electric push rod 53 are hinged to the upper part of the front support arm 48 or the upper part of the rear support arm 49, and the No. 2 reduction motor 52 and the No. 6 electric push rod 53 are electrically connected to the auxiliary electronic control system 35.
[0032] By controlling the No. 3 servo motor 44 to rotate and reducing speed through the gear reducer 43, the front track wheel 45 can be driven to rotate, thereby driving the track 47 to rotate through the rear track wheel 46, so as to realize the movement of the self-propelled track trailer. When the terrain is particularly rugged, the No. 6 electric push rod 53 is controlled to retract, and the No. 2 reduction motor 52 is controlled to drive the rear gripping wheel 51 to rotate, so that the front support arm 48 and the rear support arm 49 can be tilted upward, and at this time, they can adapt to the road surface with large potholes. When the terrain is relatively stable and the slope is small, the No. 6 electric push rod 53 is controlled to extend, and the No. 2 reduction motor 52 is controlled to drive the rear gripping wheel 51 to rotate, so that the front support arm 48 and the rear support arm 49 can be tilted downward, so that the front gripping wheel 50 and the rear gripping wheel 51 are in contact with the ground, and the track 47 is separated from the ground. At this time, it can move relatively quickly, and it is convenient to transport the electric pole A under the condition of meeting various terrains.
[0033] The flipping mechanism includes a No. 2 support shaft 54, a No. 3 support shaft 55, and a No. 7 electric push rod 56. The left and right parts of the mounting seat 2 are each fixed with a horizontal No. 2 support shaft 54, and the left and right parts of the outer wall of the main support tube 3 are each fixed with a horizontal No. 3 support shaft 55. The two No. 2 support shafts 54 are respectively hinged with a No. 7 electric push rod 56 front and back, and the push rod of the No. 7 electric push rod 56 is hinged to the No. 3 support shaft 55. The No. 7 electric push rod 56 is electrically connected to the main electronic control system 15, and the No. 3 support shaft 55 can be in contact with the top of the mounting seat 2.
[0034] By controlling the extension and retraction of the No. 7 electric push rod 56, the main support tube 3 can be turned forward and backward. When the No. 3 support shaft 55 contacts the mounting seat 2, the load on the No. 7 electric push rod 56 can be reduced, thereby reducing its wear.
[0035] The above is a preferred embodiment of the present invention.
