[0002] Gas-insulated metal-enclosed transmission lines (GIL) and gas-insulated switchgear (GIS busbars) are core power transmission equipment for underground utility tunnels and ultra-high voltage power grids. With the construction of new power systems, the demand for GIL / GIS busbars has surged; however, their transportation and installation rely on specialized equipment with high precision and high safety. Summary of the Invention

[0003] This invention provides a gripper mechanism, trolley, and handling method for GIS busbar handling, which can overcome some or all the defects of the prior art.

[0004] According to the present invention, a gripper mechanism for transporting GIS busbars includes a gripper base configured to be height-adjustable, a main gripper body being height-adjustable at the gripper base; a guide mechanism and a reset mechanism are disposed between the main gripper body and the gripper base; a secondary gripper body is hinged to the main gripper body; the reset mechanism is used to keep the main gripper body at its maximum upward stroke; when the main gripper body is pressed down by the GIS busbar to be transported, the main gripper body is at its maximum downward stroke; when the main gripper body is at its maximum upward stroke, the opening angle between the secondary gripper body and the main gripper body reaches its maximum, and the distal hinge end of the secondary gripper body is lower than the hinge end of the main gripper body; when the main gripper body is at its maximum downward stroke, the opening angle between the secondary gripper body and the main gripper body reaches its minimum, and the secondary gripper body and the main gripper body together form a semi-circular clamping space for enclosing the GIS busbar to be transported from below.

[0005] Preferably, the gripper base includes a base support and a mounting plate, the mounting plate being rotatably mounted on the base support via bearings.

[0006] Preferably, the upper end of the main gripper body forms a 1 / 4 arc-shaped main slot, and the lower end of the main gripper body forms a flat mating plane for cooperating with the mounting plate; the lower end of the main slot forms a hinge end, and multiple auxiliary gripper body mounting slots are provided at intervals at the hinge end of the main gripper body. The auxiliary gripper body includes multiple sub-auxiliary gripper bodies installed at the auxiliary gripper body mounting slots; the sub-auxiliary gripper bodies are 1 / 4 arc-shaped, and the lower end of the sub-auxiliary gripper bodies forms a hinge end. The hinge end of the auxiliary gripper body and the hinge end of the main gripper body are hinged together by a hinge shaft.

[0007] Preferably, the lower part of the hinge end of the sub-clamp body forms a pressing plane that is flush with the mating plane.

[0008] Preferably, the hinge hole for engaging with the hinge shaft on the sub-clamping jaw is located between the two ends of the pressing plane; both the hinge end and the far hinge end of the main clamping jaw are provided with a guide mechanism.

[0009] Preferably, the guiding mechanism includes a guide post located at the mounting plate and a guide hole located at the main gripper body; when the main gripper body is at the maximum downward stroke, the guide post does not extend from the top into the guide hole.

[0010] Preferably, the mounting plate has a reset mechanism mounting groove for setting the reset mechanism. The reset mechanism includes a sliding guide rod fixedly installed in the reset mechanism mounting groove. Sliding guide blocks are slidably installed at both ends of the sliding guide rod. A reset spring is installed between the sliding guide block and the corresponding side wall of the reset mechanism mounting groove. The sliding guide block cooperates with a mounting block through a hinge rod. The two ends of the hinge rod are respectively hinged to the sliding guide block and the mounting block. The mounting block is used to cooperate with the main gripper body.

[0011] The GIS busbar handling trolley according to the present invention includes a trolley body, wherein the trolley body includes any of the above-described GIS busbar handling gripper mechanisms.

[0012] Preferably, the vehicle body includes a movable frame, a support frame that can move back and forth on the frame, and a gripper mechanism that can move up and down on the support frame.

[0013] According to the GIS busbar handling method of the present invention, at least two of the above-mentioned GIS busbar handling trolleys are used to complete the installation of the GIS busbar at the bracket.

[0014] The beneficial effects of this invention include: This design allows the main and auxiliary grippers to actively close and form a clamping space when bearing load during the transport of the GIS busbar, ensuring proper clamping. After the GIS busbar is in place, as the gripper mechanism moves downward, the load on the main and auxiliary grippers gradually dissipates. At this point, the main and auxiliary grippers move upward under the action of the reset mechanism, simultaneously opening. This effectively reduces the vertical distance required for the GIS busbar to leave the clamping space, facilitating its placement in confined spaces. When the secondary gripper and the main gripper are moving the GIS busbar to be moved, the cooperation of the guide post and the guide hole can firmly resist the upward trend of the secondary gripper and the main gripper caused by the lateral force, thereby better maintaining the shape of the clamping space and preventing the GIS busbar from overturning during the movement.

Detailed Implementation

[0016] To further understand the content of this invention, the invention will be described in detail with reference to the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0017] Seen in Figure 1-4 This disclosure provides a gripper mechanism for handling GIS busbars. The gripper mechanism 100 includes a gripper base 110 configured to be height-liftable. A main gripper body 120 is height-liftable at the gripper base 110. A guide mechanism 130 and a reset mechanism 140 are disposed between the main gripper body 120 and the gripper base 110. A secondary gripper body 150 is hinged at the main gripper body 120. The reset mechanism 140 is used to keep the main gripper body 120 at the maximum upward stroke. When the main gripper body 120 is pressed down by the GIS busbar to be handled, the main gripper body 120 is at the maximum downward stroke. When the main gripper body 120 is at the maximum upward stroke, the opening angle between the secondary gripper body 150 and the main gripper body 120 reaches its maximum, and the distal hinge end of the secondary gripper body 150 is lower than the hinge end of the main gripper body 120. When the main gripper body 120 is at its maximum downward stroke, the opening angle between the secondary gripper body 150 and the main gripper body 120 reaches its minimum. The secondary gripper body 150 and the main gripper body 120 together form a semi-circular clamping space 210 for enclosing the GIS busbar to be transported from below.

[0018] Based on the above structure, when the GIS busbar to be transported is being moved, the main gripper body 120 and the auxiliary gripper body 150 can actively close to form the clamping space 210 when bearing the load, thus achieving good clamping of the GIS busbar to be transported. After the GIS busbar to be transported is placed on the support, as the gripper mechanism 100 moves downward, the load on the main gripper body 120 and the auxiliary gripper body 150 can be gradually removed. At this time, under the action of the reset mechanism 140, the main gripper body 120 and the auxiliary gripper body 150 move upward and open at the same time. This can effectively reduce the vertical distance required for the GIS busbar to be transported to leave the clamping space 210, which is conducive to the positioning of the GIS busbar in a narrow space.

[0019] The gripper base 110 includes a base support 111 and a mounting plate 112, which is rotatably mounted on the base support 111 via a bearing 310. The mounting plate 112 facilitates the coordinated operation of multiple gripper mechanisms 100.

[0020] The main gripper body 120 has a quarter-circular arc-shaped main slot 321 at its upper end and a planar mating plane 322 at its lower end for engaging with the mounting plate 112. A hinge end is formed at the lower end of the main slot 321, and multiple secondary gripper mounting slots 323 are spaced apart at the hinge end of the main gripper body 120. The secondary gripper body 150 includes multiple sub-secondary gripper bodies 151 mounted in the sub-secondary gripper mounting slots 323. Each sub-secondary gripper body 151 is quarter-circular, and its lower end forms a hinge end. The hinge end of the sub-secondary gripper body 150 is hinged to the hinge end of the main gripper body 120 via a hinge shaft 160. This design allows for a space-saving mating between the main gripper body 120 and the secondary gripper body 150.

[0021] The lower part of the hinge end of the sub-gripper body 151 forms a pressing plane 152 that is flush with the mating plane 322. This allows for better maintenance of the clamping space 210 between the sub-gripper body 150 and the main gripper body 120.

[0022] The sub-clamping jaw 151 has a hinge hole for engaging with the hinge shaft 160, located between the two ends of the pressing plane 152; both the hinge end and the far hinge end of the main clamping jaw 120 are equipped with guide mechanisms 130. This design gives the sub-clamping jaw 150 better load-bearing performance and better resistance to lateral impact, effectively preventing the GIS busbar to be transported from overturning during travel.

[0023] The guiding mechanism 130 includes a guide post 131 located at the mounting plate 112 and a guide hole 132 located at the main gripper body 120. When the main gripper body 120 is at its maximum downward stroke, the guide post 131 does not extend from the top into the guide hole 132. Based on this design, when the secondary gripper body 150 and the main gripper body 120 are moving the GIS busbar to be moved, the cooperation of the guide post 131 and the guide hole 132 can firmly resist the upward trend of the secondary gripper body 150 and the main gripper body 120 caused by lateral force, thereby better maintaining the shape of the clamping space 210 and preventing the GIS busbar from tipping over during travel.

[0024] The mounting plate 112 has a reset mechanism mounting groove 330 for mounting the reset mechanism 140. The reset mechanism 140 includes a sliding guide rod 410 fixedly mounted in the reset mechanism mounting groove 330. Sliding guide blocks 420 are slidably mounted at both ends of the sliding guide rod 410. A reset spring 430 is provided between the sliding guide block 420 and the corresponding side wall of the reset mechanism mounting groove 330. The sliding guide block 420 cooperates with a mounting block 460 through a hinge rod 440. The two ends of the hinge rod 440 are hinged to the sliding guide block 420 and the mounting block 460, respectively. The mounting block 460 is used to cooperate with the main gripper body 120. This structure can achieve the reset function with a smaller installation space, which is beneficial to reducing the overall size of the gripper mechanism 100.

[0025] In addition, see Figure 5 This disclosure also proposes a GIS busbar handling trolley, which includes a trolley body 500, and the trolley body 500 includes the aforementioned GIS busbar handling gripper mechanism.

[0026] The vehicle body 500 includes a movable frame 510, a support frame 520 that can move back and forth on the frame 510, and a gripper mechanism 100 that can move up and down on the support frame 520.

[0027] In addition, this disclosure also proposes a GIS busbar handling method, which uses at least two of the above-mentioned GIS busbar handling trolleys to complete the installation of the GIS busbar at the bracket.
