Description

Technical Field

[0001] This utility model belongs to the field of power construction technology, specifically relating to a stable support device for erecting utility poles. Background Technology

[0002] Utility poles are pole-shaped structures used to support overhead power transmission lines, communication lines, or lighting facilities. They are typically made of wood, concrete, or steel and are an important part of urban and rural power and communication infrastructure.

[0003] A utility pole erecting device is a specialized piece of equipment used to safely and efficiently erect utility poles from a horizontal position to a vertical position. It provides stable support and controllable power through a mechanical structure or hydraulic system, ensuring that the utility pole remains balanced and is accurately inserted into the pole hole during the erection process.

[0004] Patent application CN207348587U discloses a pole erecting machine for communication line construction. It uses two clamping grippers to hold and fix the utility pole to be installed. A first upper hinge block and a first lower hinge block fix the lower half of a support plate, allowing the support plate to rotate relative to the support rod. A hydraulic cylinder drives the upper half of the utility pole to move, facilitating the placement of the pole into the installation point. While this pole erecting machine can erect utility poles, in actual use, if the hydraulic cylinder is damaged or leaks, the hydraulic rod will retract, causing the support plate to rotate and lower the utility pole. Due to the weight of the utility pole, this sudden descent could injure workers, compromising their safety. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the sudden descent of utility poles in the prior art can cause injury to workers and fail to guarantee their safety, and to provide a stable support device for the erection of utility poles.

[0006] The objective of this utility model can be achieved through the following technical solutions: A utility pole erection stabilization support device includes a trolley, with symmetrically arranged support seats connected to the upper surface of the trolley near its end. A support plate is rotatably connected between the support seats. A multi-stage cylinder is installed between the lower end of the support plate away from the support seats and the trolley. The end of the support plate near the support seats passes through the support seats and is connected to a ratchet. A pawl is rotatably connected to the support seats at the position corresponding to the ratchet, and the ratchet and pawl engage. A fixing block is connected to the support seats at the position corresponding to the pawl, and a first spring is connected between the pawl and the fixing block.

[0007] Preferably, a lever is connected to the end of the pawl near the ratchet and the side away from the support seat, and a housing is connected to the middle of the side of the pawl away from the support seat, with a plug slidably connected inside the housing.

[0008] Preferably, the pawl has a first slot at the position corresponding to the insertion block, and the insertion block is inserted into the first slot. The support base has a second slot at the position corresponding to the insertion block and away from the ratchet, and the insertion block is intermittently inserted into the second slot.

[0009] Preferably, an outer ring is connected to the outside of the insert block, and the outer ring is located inside the housing. A second spring is connected between the side of the outer ring away from the pawl and the housing. The end of the insert block away from the pawl passes through the housing and is connected to the pull ring.

[0010] Preferably, a stop block is connected to the side of the support seat near the pawl, corresponding to the position of the pawl. The pawl is located between the stop block and the ratchet. A ball bearing is rotatably connected to the end of the insert block near the support seat, and the ball bearing fits against the support seat.

[0011] Preferably, the lower surface of the support plate is connected to two sets of symmetrically arranged third positioning plates, and each set of third positioning plates is rotatably connected to a bidirectional lead screw, and the outer side of each bidirectional lead screw is threaded with a symmetrically arranged movable plate.

[0012] Preferably, the upper end of each movable plate is connected to a limiting plate, and the support plate is provided with a limiting groove at the position corresponding to the limiting plate. The limiting plate is slidably connected in the limiting groove, and the upper end of each limiting plate is connected to a clamping plate.

[0013] Preferably, one end of one of the bidirectional lead screws passes through the third positioning plate and is connected to a motor fixed on the third positioning plate, and the ends of the bidirectional lead screws away from the motor both pass through the third positioning plate and are connected to sprockets, with chains meshing between the sprockets.

[0014] The beneficial effects of this utility model are: 1) During the rotation of the support plate, the ratchet rotates synchronously. The pawl, in conjunction with the first spring, keeps the pawl engaged with the ratchet. When the cylinder leaks or is damaged, causing the cylinder output end to retract, the support plate will rotate and descend. The engagement of the ratchet and pawl allows the support plate to rotate only in one direction. When the support plate rotates and descends, the ratchet and pawl work together to support the support plate, thereby supporting the utility pole. This prevents the support plate from rotating and descending, ensuring the safety of the workers and preventing injury caused by the sudden descent of the utility pole.

[0015] 2) In the initial state, the multi-stage cylinder is in the retracted state, making the support plate parallel to the horizontal plane, thus facilitating the placement of the utility pole on the support plate. After the utility pole is placed, the motor is started, and the motor drives one of the double-acting lead screws to rotate. One double-acting lead screw, in conjunction with the sprocket and chain, causes the other double-acting lead screw to rotate synchronously. During the rotation of the two double-acting lead screws, the clamping plates move closer to each other, thereby clamping and fixing the utility pole to the support plate. After the utility pole is fixed, the trolley is moved to the installation position of the utility pole. After the movement is completed, the multi-stage cylinder is started, causing the output end of the multi-stage cylinder to extend. After the multi-stage cylinder extends, it lifts the support plate, causing the support plate to rotate, thereby driving the utility pole to stand upright. During the erection of the utility pole, the clamping plates clamp the utility pole tightly, providing support and enabling the utility pole to be erected stably. This method of erecting the utility pole is convenient and quick, and provides stable support for the utility pole. Attached Figure Description

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] Please see Figure 1 - Figure 6 As shown, a utility pole erection stabilization support device includes a trolley 1, which is used to move the utility pole.

[0021] The upper surface of the trolley 1 is connected to a symmetrically arranged support seat 11 near the end, and the support seat 11 is used to fix the position of the support plate 12.

[0022] A support plate 12 is rotatably connected between the support bases 11. The support plate 12 is used to support the utility pole and assist in lifting the utility pole.

[0023] A multi-stage cylinder 14 is provided between the lower end of the support plate 12 away from the support base 11 and the trolley 1. The multi-stage cylinder 14 is used to lift the support plate 12 so that the utility pole can be erected.

[0024] The upper surface of the trolley 1 is connected to the lower end of the multi-stage cylinder 14 with symmetrically arranged first positioning plates 13. The multi-stage cylinder 14 is rotatably connected between the first positioning plates 13. The lower surface of the support plate 12 is connected to the position of the output end of the multi-stage cylinder 14 with symmetrically arranged second positioning plates 15. The output end of the multi-stage cylinder 14 is rotatably connected between the second positioning plates 15. Through the cooperation of the first positioning plates 13 and the second positioning plates 15, the multi-stage cylinder 14 can be fixed between the support plate 12 and the trolley 1.

[0025] The first positioning plate 13 and the multi-stage cylinder 14 are each provided with a first socket 16 and a second socket 18 at corresponding positions. Pins 17 are intermittently inserted into the first socket 16 and the second socket 18. In the initial state, the support plate 12 is parallel to the horizontal plane and the multi-stage cylinder 14 is perpendicular to the horizontal plane. By inserting the pins 17 into the first socket 16, the multi-stage cylinder 14 can be fixed, which enhances the stability of the multi-stage cylinder 14. After the utility pole is erected, both the support plate 12 and the multi-stage cylinder 14 are tilted. By inserting the pins 17 into the second socket 18, the multi-stage cylinder 14 can be fixed, thus ensuring the stability of the multi-stage cylinder 14 when the utility pole is removed and avoiding danger.

[0026] Two sets of symmetrically arranged third positioning plates 2 are connected to the lower surface of the support plate 12. The third positioning plates 2 are used to fix the position of the bidirectional lead screw 21.

[0027] Each group of third positioning plates 2 is rotatably connected to a bidirectional lead screw 21, which is used to drive the clamping plates 25 to move closer or further apart.

[0028] The outer side of the bidirectional lead screw 21 is threaded with symmetrically arranged movable plates 22, which are used to drive the limit plate 23 and the clamping plate 25 to move.

[0029] Each movable plate 22 is connected to a limiting plate 23 at its upper end. Each support plate 12 has a limiting groove 24 at the position corresponding to the limiting plate 23. The limiting plate 23 is slidably connected in the limiting groove 24. Through the cooperation of the limiting plate 23 and the limiting groove 24, the movable plate 22 can move stably and prevent the movable plate 22 from deflecting during the movement.

[0030] Each of the limiting plates 23 has a clamping plate 25 connected to its upper end. The clamping plate 25 is used to clamp and fix the utility pole.

[0031] One end of one of the bidirectional lead screws 21 passes through the third positioning plate 2 and is connected to the motor 26 fixed on the third positioning plate 2. The motor 26 is used to drive one of the bidirectional lead screws 21 to rotate.

[0032] The ends of the bidirectional lead screws 21 away from the motor 26 pass through the third positioning plate 2 and are connected to the sprockets 27. A chain 28 meshes between the sprockets 27. Through the cooperation of the sprockets 27 and the chain 28, the two bidirectional lead screws 21 can rotate synchronously.

[0033] In practical use, initially, the multi-stage cylinder 14 is in a retracted state, making the support plate 12 parallel to the horizontal plane, thus facilitating the placement of the utility pole onto the support plate 12. After the utility pole is placed, the motor 26 is started, driving one of the double-acting lead screws 21 to rotate. One double-acting lead screw 21, in conjunction with the sprocket 27 and chain 28, causes the other double-acting lead screw 21 to rotate synchronously. During the rotation of the two double-acting lead screws 21, the clamping plates 25 move closer together, thereby clamping and fixing the utility pole onto the support plate 12. After the utility pole is fixed, the trolley 1 is moved to the installation position of the utility pole. After the movement is completed, the multi-stage cylinder 14 is activated, causing its output end to extend. The extended cylinder 14 lifts the support plate 12, causing it to rotate and thus erect the utility pole. During the erection process, the clamping plate 25 clamps the pole, providing support and ensuring stable erection. Once erected and in the installation position, the motor 26 is activated again to move the clamping plates 25 away from each other, releasing the clamps and allowing for installation. This process is convenient and quick, and provides stable support for the utility pole.

[0034] One end of the support plate 12 near the support base 11 passes through the support base 11 and is connected to the ratchet 3. The support base 11 is rotatably connected to the ratchet 3 at the position corresponding to the ratchet 3. The ratchet 3 and the ratchet 31 mesh. Through the cooperation of the ratchet 3 and the ratchet 31, the support plate 12 can be stably supported when the support plate 12 rotates to erect the utility pole.

[0035] A fixing block 32 is connected to the support base 11 at the position corresponding to the pawl 31. A first spring 33 is connected between the pawl 31 and the fixing block 32. The first spring 33 is used to reset the pawl 31.

[0036] A lever 4 is connected to one end of the pawl 31 near the ratchet 3 and the side away from the support 11. The lever 4 can rotate the pawl 31 to a position away from the ratchet 3.

[0037] A housing 41 is connected to the middle of the side of the pawl 31 away from the support base 11. A plug 42 is slidably connected inside the housing 41. The housing 41 is used to store the plug 42, and the plug 42 is used to fix the position of the pawl 31.

[0038] The pawl 31 has a first slot 43 at the position corresponding to the insertion block 42. The insertion block 42 is inserted into the first slot 43, which is used to store the insertion block 42.

[0039] The support base 11 has a second slot 44 at a position corresponding to the insert 42 and away from the ratchet 3. The insert 42 is intermittently inserted into the second slot 44. Through the cooperation between the insert 42 and the second slot 44, the pawl 31 can be fixed at a position away from the ratchet 3.

[0040] An outer ring 45 is connected to the outside of the plug 42, and the outer ring 45 is located inside the housing 41. A second spring 46 is connected between the side of the outer ring 45 away from the pawl 31 and the housing 41. The second spring 46 is used to reset the plug 42.

[0041] The end of the insert 42 away from the pawl 31 passes through the housing 41 and is connected to the pull ring 47, which is used to remove the insert 42 from the second slot 44.

[0042] A stop block 48 is connected to the side of the support base 11 near the pawl 31, corresponding to the position of the pawl 31. The pawl 31 is located between the stop block 48 and the ratchet 3. With the cooperation of the stop block 48, after the pawl 31 rotates away from the ratchet 3, the stop block 48 can block the pawl 31, so that the insert block 42 can be aligned with the second slot 44.

[0043] The end of the insert 42 near the support base 11 is connected to a ball bearing 49. The ball bearing 49 fits against the support base 11. The friction between the insert 42 and the support base 11 can be reduced through the cooperation of the ball bearing 49.

[0044] In practical use, the support plate 12 drives the ratchet 3 to rotate synchronously during rotation. The pawl 31 cooperates with the first spring 33 to keep the pawl 31 engaged with the ratchet 3. When the cylinder leaks air or is damaged and causes the cylinder output end to retract, the support plate 12 will rotate and fall. The engagement of the ratchet 3 and the pawl 31 will allow the support plate 12 to rotate only in one direction. When the support plate 12 rotates and falls, the ratchet 3 and the pawl 31 can support the support plate 12, thereby supporting the utility pole. This can prevent the rotation and falling of the support plate 12 and prevent the sudden falling of the utility pole from causing injury to the staff, thus ensuring the safety of the staff. When the support plate 12 needs to be reset after the pole erection is completed, the lever 4 is moved away from the ratchet 3, causing the pawl 31 to rotate away from the ratchet 3. During the rotation, the pawl 31 will compress the first spring 33, causing the first spring 33 to contract and store the restoring force. After the pawl 31 rotates and fits against the stop block 48, the insert block 42 corresponds to the second slot 44. Under the action of the restoring force of the second spring 46, the insert block 42 is reset and inserted into the second slot 44, thereby fixing the pawl 31. After the pawl 31 is fixed, the multi-stage cylinder 14 can be activated to drive the support plate 12 to reset to the initial position. After the support plate 12 is reset, pull the pull ring 47 to move the insert block 42 out of the second slot 44. During the process of the insert block 42 moving out of the second slot 44, the outer ring 45 compresses the second spring 46. The second spring 46 will contract and store the restoring force when compressed, in preparation for the next insertion of the insert block 42 into the second slot 44. After the insert block 42 moves out of the second slot 44, under the action of the restoring force of the first spring 33, the pawl 31 is reset and re-engaged with the ratchet 3, so that the support plate 12 can only rotate in one direction again. This makes it more convenient to fix the pawl 31 and reset the pawl 31, which can improve work efficiency.
