Description

Pneumatic lifting high-altitude grounding device

technical field

Background technique

Grounding (earthing) refers to the neutral point of the power system and electrical devices, the exposed conductive parts of electrical equipment and the conductive parts outside the device are connected to the earth through conductors. In the power system, the ground wire is an important tool to ensure the safety of the staff when the voltage appears unexpectedly on the equipment and lines that have been powered off. The function of the grounding wire is to prevent the human body from being harmed by the sudden call of the equipment or the induced voltage generated by the adjacent high-voltage live equipment when the high-voltage equipment is powered off for maintenance or other work, and at the same time discharge the residual charge of the power-off equipment.

Installing and removing temporary ground wires is an important maintenance operation in power systems. At present, the short-circuit grounding wire is usually used in the maintenance work of the substation equipment in the substation, and the short-circuit grounding wire is mainly hung on the maintenance equipment or the wire by using an insulating operating rod. However, at the substation maintenance site, the grounding point of some equipment is too high, and it is very difficult for the staff to hang the grounding wire manually. Voltage equipment is more suitable, but for open equipment with a voltage level of 500 kV and UHV equipment of 1000 kV, due to the large insulation distance of the equipment, the installation height of the equipment is relatively high, and it is difficult to use the method of manually hanging wires on insulating rods. Use bucket trucks to send workers to high places and hang them manually; relying on high-altitude bucket trucks has high requirements for workers and high risk factors.

Detailed ways

Referring to Figures 1 to 3, the pneumatic lifting high-altitude grounding device of the present invention includes a grounding clamping mechanism and a lifting device 14;

The ground clamping mechanism includes a base 1, the top of the base 1 is provided with a wiring pile head 2 and a clamping arm, and the wiring pile head 2 is connected with a grounding wire 3; the clamping arm has two, respectively It is the first clamp arm 4 and the second clamp arm 5; the first clamp arm 4 and the second clamp arm 5 are hinged with the top of the base 1 through the hinge 6; the first clamp arm 4 and the A mobile chuck 7 is sleeved on the second clamp arm 5. When the mobile chuck 7 moves up, the distance between the two clamp arms decreases to realize the clamping action. When the mobile chuck 7 moves down, the two clamps The distance between the arms is increased to realize the release action; the inside of the base 1 is arranged in a threaded hole, and a rotating shaft 8 passes through the threaded hole, and the rotating shaft 8 is threadedly connected to the threaded hole; The upper end of the rotating shaft 8 is connected with the movable chuck 7 through a bearing 13; a clamping plate 9 is fixed at the lower end of the rotating shaft 8;

The lifting device 14 includes a base 20, a four-claw clamp 12, a rotating shaft 16, a high-definition camera 17, a multi-section lifting rod 18, a tripod 15 and an air source interface 21;

The outer peripheral surface of the base 20 is provided with the tripod 15; the multi-section lifting rod 18 is arranged in the inner cavity of the base 20, and the air source interface 21 is arranged at the lower end of the outer peripheral surface of the base 20, The air source interface 21 provides air pressure for the multi-section lifting rod 18 to drive the multi-section lifting rod 18 to expand and contract in a straight line along the vertical direction; On the outer periphery; the rotating shaft 16 is located at the top of the uppermost section of the multi-section lifting rod 18, driven by a rotating motor; the four-jaw clip 12 is located at the top of the rotating shaft 16;

The tripod 15 includes three legs; the legs include a support foot 1501 and a support rod 1502; On the ground: one end of the support rod 1502 is hinged to the middle of the support foot 1501 , and the other end of the support rod 1502 is hinged to the lower end of the outer peripheral surface of the base 20 .

During maintenance, the base is fixed on the ground. A tripod helps to increase the stability of the base. The multi-section elevating rod 18 is a pneumatic elevating rod, which can be telescopically adjusted in height under the control of pneumatic pressure. Connect the external air source through the air source interface 21 to provide air pressure to drive the pneumatic lifting rod up and down. The air source is used for lifting drive. Compared with the hydraulic drive mode, it is cleaner and avoids the problem of oil leakage in the hydraulic mode. The pneumatic response is fast, the action is fast, the maintenance is simple, and the pipeline is not easy to block.

Three legs of the tripod 15 are evenly distributed on the outer peripheral surface of the base. When it needs to be opened, just pull the lower ends of the supporting legs outwards. Since the supporting feet and the supporting rods are all hinged and connected to the base, the supporting feet and the supporting rods can be retracted to be close to the outer peripheral surface of the base, which saves space and is convenient for storage. During specific implementation, grooves can be provided on the outer peripheral surface of the base to accommodate the legs, so that the tripod can be completely retracted into the grooves, making the appearance of the lifting device 14 more beautiful.

When the lift reaches a suitable position, the controller turns on the rotating motor to control the rotation of the four-jaw clamp, and then drives the clamping plate and the rotating shaft to rotate. At the same time, the clamping plate, rotating shaft and moving chuck move linearly to control the clamping arm. Open and clamp.

The clamping plate 9 is connected with a four-claw clamp 12 and driven to rotate by the four-claw clamp 12 . When the clamping plate 9 rotates, it drives the rotating shaft to rotate. The rotating shaft is threadedly connected with the base, and a screw nut pair is formed between the two. The base is fixed and is equivalent to a nut, and the rotating shaft is equivalent to a screw. Therefore, when the rotating shaft rotates, it also moves axially in the threaded hole, thereby driving the movable chuck to move up and down, thereby realizing the clamping and releasing of the two clamping arms. During specific work, the chucks of the two clamping arms are used to clamp the maintenance equipment or wires, thereby realizing the grounding of the maintenance equipment or wires. The conductive connection between the grounding pile head, the grounding wire and the clamping arm is to realize the grounding function.

Both the first clamping arm 4 and the second clamping arm 5 include a chuck 10 and a rod body 11; the bottom end of the rod body 11 is hinged on the top of the base 1, and the chuck 10 is provided with the top end of the rod body 11 ; The clips 10 of the two clamp arms are arranged opposite to each other, and when the clips 10 of the two clamp arms are engaged with each other, they can just clamp the wire.

The inner side of the chuck is a concave arc-shaped groove, and when the two chucks abut against each other, the two arc-shaped grooves are engaged with each other to just clamp the wire.

The base 1 includes a cylinder 101 and a frustum of a cone 102, the cylinder 101 is located above the frustum of a cone 102 and the two are coaxially arranged; the clamp arm is located at the top of the cylinder 101; the threaded hole is located at the top of the cylinder 101 is centered and coaxial with the cylinder 101; the frustum 102 is a hollow structure; the clamping plate 9 is located in the inner cavity of the frustum 102.

The clamping plate 9 is composed of two intersecting plate bodies.

The two boards intersect each other perpendicularly, or cross in an X shape, forming four mutually isolated areas. The four claws 1201 of the four-jaw clip 12 are respectively located in one area. When the four-jaw clamp 12 rotates, it also drives the clamping plate to rotate. When the clamping plate rotates, it will move linearly along the axis of the base along with the rotating shaft, and the clamping plate also moves in the four-claw clamping. Since the four-claw clamp has a certain depth, that is, the claws have a certain height, the clamping plate will not be separated from the four-claw clamp. The four-jaw clip 12 is located at the top of the lifting device.

During specific implementation, the ground clamping mechanism is arranged at the top of the lifting device 14 as shown in FIG. 2 . The ground clamping mechanism is placed on the top of the lifting device, and the clamping plate 9 and the four-jaw clamping clamp 12 are clamped to each other. When the ground clamping mechanism is arranged on the top of the lifting device, the clamping plate 9 is just clamped with the four-claw clamp 12; The claw clip 12 moves up and down within the height range. In order to stabilize the lifting device 14 on the ground, a tripod 15 is set at the lower end of the lifting device.

The four-jaw clamp 12 is fixed on a rotating shaft 16, and the rotating shaft 16 is driven by a motor. When the motor drives the four-jaw clamp 12 to rotate, it will drive the clamping plate to rotate, thereby driving the rotating shaft and the moving chuck to move along the axial direction of the base, thereby realizing the clamping and releasing of the two clamping arms.

As shown in Fig. 1, two holes are arranged on the mobile chuck, and the rod body of each clamp arm is inserted into one hole. The bottom ends of the rod bodies of the two clamping arms are hinged on the base, and the distance between the hinged parts of the two clamping arms is smaller than the distance between the two holes of the moving chuck; The descent stops above the hinge. Moreover, since the distance between the two holes is fixed, and it is set so that when the movable chuck moves to the top of the rod body of the clamp arm, the chucks of the two clamp arms just engage with each other to realize the clamping action of the chuck. When the moving chuck descends from the top of the rod body, the distance between the two chucks increases to realize the release action of the chucks. The lifting of the mobile chuck is controlled by the rotating motor of the four-jaw clamp.

In the high-altitude grounding device of the present invention, the grounding clamping mechanism needs to be equipped with a lifting device 14 for use.
