Description

Technical Field

[0001] The present invention relates to the technical field of spacer bar installation, and in particular to a spacer bar installation system based on an unmanned aerial vehicle. Background Art

[0002] It is well known that at present, when installing spacers, the installers need to climb to the top of the power tower with the spacers, and then, while connecting the safety rope to ensure the safety of the personnel, they need to reach the position that needs support along the power line, and then clamp and connect the multiple wire clamps of the spacer to the corresponding wires in sequence; since the spacer itself is heavy, it is not only difficult to transport, but also in the middle position of the wire far away from the power tower, the workers need to clamp each wire clamp and tighten the bolts while ensuring their own support safety. If the distance between the two power towers is 300 to 400 meters, then at least five spacers must be installed between the two adjacent power towers. The traditional connection method is very physically demanding and not only cumbersome to operate, but also requires workers to be in a suspended working environment for a long time and to carry out construction with heavy loads, which poses a great safety risk. Summary of the invention

[0003] In order to overcome the deficiencies in the background technology and solve the existing technical problems, the present invention discloses a spacer rod installation system based on a drone, which can be manually pre-installed near a power tower and use drones to reduce construction difficulty and installation risks.

[0004] To achieve the above object, the present invention adopts the following technical solution: A spacer rod installation system based on a drone comprises a drone body, a spacer ring, and a plurality of wire clamps uniformly arranged and installed on the outer ring surface of the spacer ring, wherein the spacer ring body is connected with a lifting lug, and a hook corresponding to the lifting lug is hoisted on the lower surface of the drone body; the wire clamp comprises a wire clamp ring composed of a fixed arc segment and a movable arc segment, wherein one end corresponding to the fixed arc segment and the movable arc segment is rotatably connected, and the outer walls of the other ends corresponding to the fixed arc segment and the movable arc segment are respectively connected with a fixed arm rod and a movable arm rod, and the fixed arm rod and the movable arm rod are detachably connected by bolts The inner arc surfaces of the fixed arc segment and the movable arc segment are both fixed with elastic insulating liners; the inner ring surface of the wire clamp ring is evenly provided with a plurality of grooves, an insulating ball is movably provided in each groove, a spring is provided between the insulating ball and the bottom of the corresponding groove, and the elastic insulating liners are provided with exposure holes corresponding to the grooves, and the inner end hole wall of the exposure hole is in an arc-shaped closing shape that is adapted to the contact of the insulating ball and can expose part of the sphere; the rod wall of the fixed arm rod is fixed with a staple and one end of a strap, and the other end of the strap is provided with a clamping hole that can be sleeved with the staple after the strap passes around the movable arm rod.

[0005] Furthermore, two spaced-apart connecting plates are fixed to the end face of the movable arm, the gap between the two connecting plates is suitable for the screw portion of the bolt to pass through and is smaller than the outer diameter of the bolt head, and the rod body of the fixed arm is provided with a threaded hole for threading the screw portion of the bolt.

[0006] Furthermore, the wire clamps are provided in three or four numbers, and the heads of the bolts are arranged upward or correspondingly arranged on the side of the spacer ring.

[0007] Furthermore, a suspension rod is connected to the center of the lower surface of the drone body, the bottom end of the suspension rod is rotatably connected to a swing rod that is controlled to swing by a motor, the hook is connected to one end of the swing rod, the other end of the swing rod is connected to an automatic screw gun corresponding to the bolt, and a camera is installed on one side of the lower surface of the drone body close to the automatic screw gun.

[0008] Furthermore, the boom is configured as an electric telescopic boom.

[0009] Furthermore, the number of the grooves is four or six.

[0010] Furthermore, the insulating ball is made of ceramic material or polytetrafluoroethylene material.

[0011] Furthermore, an abutment sleeve made of the same material as the insulating ball is embedded in the inner end hole wall of the exposure hole.

[0012] Furthermore, the maximum exposed height of the insulating ball is 0.8 times the radius of the insulating ball.

[0013] Furthermore, the rod walls of the fixed arm rod and the movable arm rod are both provided with slots for corresponding binding straps to be inserted into.

[0014] Due to the adoption of the above-mentioned technical solution, the present invention has the following beneficial effects: The spacer bar installation system based on the drone disclosed in the present invention can first use the drone body to hook the lifting ear of the spacer bar and lift the spacer bar to the top of the power tower. Then the staff can operate the fixed arc segment and the movable arc segment near the top of the power tower with stable support and safety protection, so that the fixed arc segment and the movable arc segment are in a state of wrapping the wire but not tightened by using the binding straps. At this time, since the wire clamp ring is only hung on the wire, each wire clamp ring only shares a small part of the gravity of the entire spacer bar, and the insulating ball can expose the elastic insulating lining under the action of the spring, and roll against the wire. The entire spacer bar can also rely on the traction of the drone body and the rolling contact of the insulating ball to move and transport along the wire, so that the workers can pre-install multiple spacer bars needed in advance in a safe position near the power tower, and then push the spacer bar forward along the wire, tighten the bolts every 50 to 60 meters to squeeze the wire clamp ring, and completely install a spacer bar, which not only saves time and effort, but also greatly reduces the potential risk of suspended load installation in the middle of the wire due to the improved safety of pre-installation.

The drone body 4 is used to transport the entire spacer bar by hooking the hook 6 and the lifting lug 3. The wire clamp 1 comprises a wire clamp ring composed of a fixed arc segment 102 and a movable arc segment 103, so as to be able to adapt to clamp the wire, the fixed arc segment 102 and the movable arc segment 103 are rotatably connected at one end corresponding to the fixed arc segment 102 and the movable arc segment 103, and the outer walls of the other ends corresponding to the fixed arc segment 102 and the movable arc segment 103 are respectively connected with a fixed arm 104 and a movable arm 114, and the fixed arm 104 and the movable arm 114 are detachably connected by a bolt 112, and when the fixed arm 104 and the movable arm 114 are close to each other and tightly connected, the fixed arc segment 102 and the movable arc segment 103 are also completely closed, and the entire rotating clamping structure is similar to the existing clamping structure, and the inner arc surfaces of the fixed arc segment 102 and the movable arc segment 103 are fixed with an elastic insulating lining 101, which can protect the wire while ensuring insulation; The inner ring surface of the wire clamp ring is evenly provided with a plurality of grooves 107. As required, four or six grooves 107 can be provided, and they are symmetrically arranged on the fixed arc segment 102 and the movable arc segment 103 to ensure that the number of insulating balls 105 can achieve the effect of rolling support for the wire; an insulating ball 105 is movably provided in each groove 107, and the insulating ball 105 is made of ceramic material or polytetrafluoroethylene material, which has good insulation while ensuring a certain support hardness; a spring 106 is provided between the insulating ball 105 and the bottom of the corresponding groove 107, and the elastic insulating lining 101 is provided with an exposure hole 111 corresponding to the groove 107, and the inner end hole wall of the exposure hole 111 is adapted to the insulating ball 105 to contact, and a part of the ball can be exposed. The insulating ball 105 can contact the inner end hole wall of the exposure hole 111 under the action of the elastic force of the spring 106, and expose a part of the ball for rolling contact; As needed, a contact sleeve 113 made of the same material as the insulating ball 105 is embedded in the inner end hole wall of the exposed hole 111, thereby reducing the direct contact area between the insulating ball 105 and the elastic insulating lining 101 and increasing the rotation flexibility of the insulating ball 105; in addition, the maximum exposed height of the insulating ball 105 is 0.8 times the radius of the insulating ball 105, which is convenient for contacting the wire during pre-installation; the rod wall of the fixed arm 104 is fixed with a staple 109 and one end of the strap 110, and the other end of the strap 110 is provided with a hole that can be socketed with the staple 109 after the strap 110 passes around the movable arm 114, and the cooperation between the hole and the staple 109 facilitates quick disassembly and assembly; as needed, the rod walls of the fixed arm 104 and the movable arm 114 are provided with a slot 108 corresponding to the strap 110, and the slot 108 can prevent the strap 110 from moving up and down and detaching from the movable arm 114 connected to the movable arc segment 103.

[0019] The drone-based spacer installation system of the present invention can first use the hook 6 connected to the drone body 4 to hook the lug 3 of the spacer, and then lift the spacer to the top of the power tower. Then the staff can pre-install the spacer near the top of the power tower with stable support and safety protection, that is, the fixed arc segment 102 and the movable arc segment 103 can be wrapped around the wire first, and the binding band 110 can be used to prevent the two fixed arm rods 104 and the movable arm rod 114 from being completely separated, so that the wire clamp ring is just hung on the wire and is in a state where the wire is not tightened. At this time, the wire clamp ring is not tightened. The edge ball 105 can expose the elastic insulating lining 101 under the action of the spring 106, and roll against the wire, so that it can be moved and transported along the wire by relying on the traction of the drone body 4 and the rolling contact of the insulating ball 105. When the spacer rod is delivered to the right place, the bolt 112 is used to tighten and fix the arc segment 102 and the movable arc segment 103. At this time, the spring 106 is forced to retract into the groove 107, and the wire can directly contact the elastic insulating lining 101. The spring 106 provides a reverse pre-tightening force for the bolt 112, thereby enhancing the stability of the connection of the bolt 112 and preventing the connection from loosening. Embodiment 2:
