Description

Technical Field

[0001] The invention belongs to the technical field of material transportation, and in particular relates to a portable transfer device for inspecting and repairing transmission line towers. Background Art

[0002] During the maintenance of transmission line towers, different tools are required. When electrical components need to be replaced during the maintenance process, they need to be carried with them. Since towers are usually high, it is not convenient to climb up and down the towers. In addition, there are many safety hazards when carrying many tools and electrical components to climb the towers. For safety reasons, it is necessary to use a transfer device to transfer these items from the ground to the top of the tower, and when they are not needed, these items are passed down so that maintenance personnel can climb down from the tower smoothly.

[0003] The utility model patent with the authorization announcement number: CN210914339U discloses a portable transmission device for the inspection and maintenance of a power transmission line tower, comprising a rope wheel with a pull rope wound around it, a fixing mechanism for fixing the rope wheel, and an operating mechanism for operating the rope wheel to realize the transmission of articles; the rope wheel comprises a first wheel disc and a second wheel disc fixedly connected by a rotating drum and arranged opposite to each other, and the pull rope is wound on the rotating drum; the fixing mechanism comprises an inverted U-shaped fixing seat buckled on the tower, the length of the outer connecting plate of the fixing seat clamped on the tower is shorter than the length of the inner connecting plate, a threaded hole is provided on the outer connecting plate, a threaded column with a fixing handle for clamping the fixing seat on the tower is equipped in the threaded hole, a positioning shaft is fixedly provided on the outer end surface of the inner connecting plate, the rotating drum is sleeved on the positioning shaft and positioned by a nut screwed to the end of the positioning shaft; the operating mechanism comprises a U-shaped fixing groove fixedly provided on the outer end surface of the first wheel disc and a rotating handle hinged in the fixing groove through a pin shaft;

[0004] The maintenance personnel can carry the device to the pole tower operation point with a tool kit, install the fixing seat buckle on the pole tower, and fix the device by screwing the fixing handle; then rotate the rotating handle out of the fixing slot, keep it vertical with the first wheel, turn the handle counterclockwise by hand, and lower the free end of the pull rope connected to the hook to the ground. After the ground workers fix the items on the hook; the maintenance personnel on the pole tower push the rope wheel to one side of the fixing seat to engage the anti-reverse ratchet and the anti-reverse fork, and then tighten the nut on the outer positioning shaft of the second wheel to fix the rope wheel; then the maintenance personnel turn the handle clockwise by hand to wind the pull rope around the drum, and transport the items on the ground to the positioning point of the pole tower.

[0005] It can be seen that this type of transfer device requires the manual force of the maintenance personnel to pull the items up. During the entire operation, the maintenance personnel need to use both hands to perform the operation. Due to the high height of the pole tower, this operation method is not only laborious but also has certain safety hazards. Secondly, when pulling objects through the hook, the pull rope swings, which can easily cause the objects to be hung in other areas of the pole tower.

[0006] Another method is to use an electric hoist to transfer items, but the electric hoist itself is heavy, and it needs to be powered by a power supply connected to the pole tower. Secondly, the wire rope of the electric hoist may also swing. Summary of the invention

[0007] The object of the present invention is to provide a portable transmission device for power transmission line tower maintenance to solve the problems existing in the prior art.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a portable transmission device for power transmission line tower maintenance, comprising a top plate and a movable hanging buckle arranged on the top of the top plate, a cover is arranged at the bottom of the top plate, a movable seat is inserted in the cover, an installation sleeve is arranged at the center of the bottom of the top plate, and a belt piece is connected to the installation sleeve;

[0009] The belt piece is inserted into the moving seat, a hanging ring is connected to the bottom of the moving seat, and a belt conveying mechanism is provided on the moving seat and the belt piece, and the belt conveying mechanism is used to drive the moving seat to move up and down along the belt piece;

[0010] Side strips are arranged on both sides of the belt piece, conductive strips are arranged inside the side strips, and shift strips are arranged outside the side strips. Power-taking mechanisms are arranged at the front and rear parts of the movable seat, and the power-taking mechanisms are used to pass through the shift strips and contact the conductive strips, and supply power from the conductive strips to the belt conveying mechanism;

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The portable transfer device for power transmission line tower maintenance in the present invention is not only convenient for maintenance personnel to carry when climbing the tower, but also does not need the maintenance personnel to bear the power of transferring the items with their hands during the transfer process. Moreover, under the influence of the pre-tightening mechanism, the belt piece is kept in a taut state. It is only necessary to avoid the tower components when installing the belt piece in the early stage, which can not only avoid swinging when transferring the items, but also avoid the items being hung on other areas of the tower. Compared with other electric-driven conveying devices, while ensuring its portability and stable transfer of items, maintenance personnel do not need to temporarily connect electricity from the top of the tower for operation, which is convenient to operate and has high safety.

[0063] Through the elastic support of the second supporting spring piece 66 , the second conductive piece 65 keeps in contact with the conductive bar 21 , so that the power on the battery 60 is stably transmitted to the conductive bar 21 .

[0064] One end of the conductive sheet 2 65 is welded with a stud 2 67, one end of the stud 2 67 slides through the movable disk 2 63 and is sleeved with a terminal piece 2 68, a nut 3 69 is screwed on the stud 2 67, and by locking the nut 3 69, the conductive sheet 2 65 and the terminal piece 2 68 are stably electrically connected, and a terminal head 2 70 is integrally provided on one side of the terminal piece 2 68, and the terminal head 2 70 is connected to the power control input end of the forward and reverse controller 61 through a cable, and the main power input end of the forward and reverse controller 61 is connected to the power terminal post of the battery 60 through a cable.

[0065] Under the control of the forward and reverse controller 61 , the direction of the current supplied by the battery 60 into the conductive strip 21 is changed, thereby controlling the forward and reverse rotation of the motor 28 , so that the belt feeding mechanism changes its upward and downward movement direction along the belt piece 16 .

[0066] The working principle of this embodiment is as follows:

[0067] When the maintenance personnel use the transfer device, they first pull the handle 12 outward to make the oblique head insertion rod 11 disengage from the oblique head groove, pull the movable seat 10 down to disengage from the cover 9, and pull the movable seat 10 to the other end of the belt piece 16. The maintenance personnel only need to hang the anti-drop buckle 8 into the rope buckle at their waist to climb the pole tower. When reaching a high place, they can hang the movable hook on the cross arm or support pole of the pole tower.

[0068] The lower assistant first drives the positioning rod 54 into the ground according to the position of the belt piece 16, and pre-tightens the belt piece 16 through the clamping mechanism. After the installation of the holding mechanism is completed, the thread sleeve 50 is rotated and moved downward along the screw rod 52 by rotating the knob 51 in the forward direction, and the value displayed by the tension measuring meter 46 is observed to determine the tension of the belt piece 16. When the required tension value is reached, the rotation of the knob 51 is stopped, and the tension of the belt piece 16 can be stabilized. During this period, the power supply mechanism can move to the corresponding position along the belt piece 16 to prevent it from affecting the transportation of the goods.

[0069] The forward and reverse controller 61 can be controlled to control the forward rotation of the motor 28 so that the moving seat 10 moves to the lower part. The assistant can put the required items into the nylon storage bag and tie the bag rope of the nylon storage bag to the hanging ring 17, and then operate the forward and reverse controller 61 to control the reverse rotation of the motor 28. The walking shafts 18 on both sides rotate towards each other. Through the meshing cooperation between the walking shafts 18 and the belt piece 16, the moving seat 10 can be stably moved upward along the belt piece 16 until the moving seat 10 moves into the cover 9. When the top of the moving seat 10 moves up and pushes against the lower inclined surface of the oblique head insertion rod 11, the oblique head insertion rod 11 moves outward, and the spring 13 is stretched until the oblique head insertion rod 11 is aligned with the oblique head groove. Through the elastic support of the spring 13, the oblique head insertion rod 11 is inserted into the oblique head groove, thereby limiting the moving seat 10 from escaping from the cover 9, the contact of the limit switch 101 is pressed to disconnect the power supply, and the motor 28 stops running.

[0070] After the items are used, the maintenance personnel can put the items back into the nylon bag and tie the bag rope of the nylon bag to the hanging ring 17. The assistant at the bottom operates the forward and reverse controller 61 to control the forward rotation of the motor 28 until the moving seat 10 moves down to contact the soft plate 39, stops operating the forward and reverse controller 61, and the motor 28 stops running.

[0071] Clamping mechanism and pre-tightening mechanism: The clamping mechanism clamps the belt piece 16, and the pre-tightening mechanism tightens the belt piece 16, thereby tightening the belt piece 16, making the movement of the belt conveying mechanism, the power taking mechanism and the movable seat 10 more stable.

[0072] Power supply mechanism, belt conveying mechanism, power taking mechanism and conductive strip 21: under the power supply control of the power supply mechanism, power is delivered by the conductive sheet 21. Since the power taking mechanism maintains a sliding electrical connection with the conductive sheet 21, the power taking mechanism supplies power to the belt conveying mechanism in real time. The power supply mechanism changes the direction of current, thereby controlling the running direction of the belt conveying mechanism, thereby changing the up and down moving direction of the movable seat 10 along the belt sheet 16.

[0073] Therefore, this kind of transfer device is easy for maintenance personnel to carry when climbing the pole tower. In the process of transferring items, maintenance personnel do not need to rely on their hands to bear the power of transferring items, and under the influence of the pre-tightening mechanism, the belt piece 16 is kept in a taut state. It is only necessary to avoid the pole tower components when installing the belt piece 16 in the early stage, which can not only avoid swinging when transferring items, but also avoid the items being hung on other areas of the pole tower.

[0074] Compared with other electric-driven conveying devices, it does not require maintenance personnel to temporarily connect electricity from the top of the tower to operate, while ensuring its portability and stability of the transferred items.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
