Description

Technical Field

[0001] The invention relates to the technical field of GIL transmission line installation, in particular to a GIL on-site cylinder docking vehicle. Background Art

[0002] GIL (Gas Insulated Metal Enclosed Transmission Line) is a high-voltage, high-current power transmission equipment that uses gas insulation, including conductors, casings, and insulators. The conductors and casings are filled with SF6 mixed gas. Transmission lines are usually formed by connecting multiple GIL busbars. The use of GIL realizes ultra-high voltage transmission and ultra-distance transmission. This transmission method has the advantages of compact layout, large transmission capacity, and high reliability.

[0003] When installing GIL in a tunnel, the commonly used method is to preset a hook on the top of the tunnel, and then use a sling to pass through the hook to lift the GIL cylinder for docking installation. The existing installation method using a preset hook has the following problems:

[0004] 1. Lifting is suitable for lifting the GIL cylinder in the vertical direction, but not suitable for horizontal movement;

[0005] 2. The GIL cylinder needs to be rotated when the flange is connected. After lifting, it is difficult to rotate the cylinder. Forced rotation will wear the outer wall of the cylinder and affect the appearance and quality.

[0006] 3. The lifting and docking relies on manpower for adjustment, which is time-consuming, labor-intensive and inefficient;

[0007] 4. The hoisting adjustment accuracy is low, and the balance, stability and accuracy of the GIL cylinder during the docking process cannot be guaranteed;

[0008] 5. This method cannot be implemented for some tunnels that do not have preset hooks on the top of the tunnel. Summary of the invention

[0009] The purpose of the present invention is to solve at least one of the above-mentioned problems, and this purpose is achieved through the following technical solutions.

[0010] The present invention provides a GIL on-site barrel docking vehicle, comprising:

[0011] It comprises a lifting device, a sliding device arranged on the lifting device, and an adjustment frame arranged horizontally on the lifting device; wherein,

[0012] The lifting device is used to adjust the raising or lowering of the GIL busbar in the vertical direction; the lifting device includes a lifting handle for raising or lowering it.

The upper and lower parts of the slide rail are respectively connected to the slider and the lifting device, and the limit block is arranged at the end of the slide rail. The sliding device is arranged on the lifting device in a lifting manner.

[0015] The base of the lifting device is provided with casters, and the casters enable the lifting device to move at any position in the tunnel.

[0016] The supporting device includes a roller, a vertical seat bearing, a stopper, a locking bolt, and a pad. The roller is connected to the vertical seat bearing, the vertical seat bearing is fixed to the sliding device through the pad, and the stopper is connected to the roller through the locking bolt. The rollers are symmetrically arranged to support the GIL cylinder and realize the movement of the GIL cylinder along the axial direction. A screw hole is opened at the axis of the roller end, and the stopper is connected to the screw hole at the roller end through the locking bolt.

[0017] The rotating device includes a handwheel, a push rod, a pressure block, a thrust bearing, a connecting shaft, a connecting plate, a bearing, and a sleeve. The handwheel is symmetrically arranged, the connecting plate is connected to the supporting device, the lower end of the pressure block is connected to the connecting plate, the push rod passes through the pressure block, one end of which is connected to the handwheel, and the other end is connected to the connecting shaft.

[0039] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] The present invention provides a GIL on-site cylinder docking vehicle, which is used for the installation of GIL pipelines and can fix the pipelines to be installed. Figure 1-2 In a specific embodiment, the GIL on-site cylinder docking vehicle of the present invention includes a lifting device 1, an adjustment frame 2 and a sliding device 3.

[0041] In this embodiment, the lifting device 1 can be a hydraulic or electric stacker, and casters 12 are connected to the bottom of the lifting device 1. Preferably, the casters 12 include at least two universal wheels, and the setting of the casters 12 can adjust the lifting device 1 to move to any position in the tunnel. In other embodiments, the lifting device can be other mechanisms, such as a screw lift, a guide rail lift, etc.

[0042] The GIL busbar 4 is horizontally placed on the adjustment frame 2, and the adjustment frame 2 is horizontally arranged on the fork of the lifting device 1. The bottom of the adjustment frame 2 is connected to the sliding device 3 to enable the adjustment frame 2 to slide along the slide rail 31 in a plane. The sliding device 3 is arranged on the fork of the lifting device 1 in a liftable manner. Pressing the lifting handle 11 up and down can make the fork of the lifting device 1 rise or fall, thereby adjusting the rise or fall of the GIL busbar 4 in the vertical direction.

[0043] Figure 3 The adjustment frame 2 is provided with a GIL cylinder support device 21 and a rotating device 22 that allows the GIL cylinder to rotate around an axis.

[0044] In this embodiment, the support device 21 includes a roller 211, a vertical seat bearing 212, a stop 213, a locking bolt 214, and a pad 215. The roller 211 is symmetrically arranged to support the GIL cylinder. The shape of the roller 211 can be processed to fit the outer wall of the GIL cylinder to improve the support stability. Furthermore, the surface of the roller 211 needs to be coated with a layer of soft material to avoid scratching the GIL cylinder wall. The roller 211 is connected to the bearing hole of the vertical seat bearing 212, and the vertical seat bearing 212 is connected by bolts and The backing plate 215 is connected, and the backing plate 215 is fixed on the sliding device 3 by bolts. The sliding device 3 can realize the lateral (X direction) movement of the GIL cylinder in the plane, and the rotation of the roller 211 can realize the movement of the GIL cylinder along the axial direction (Y direction). Furthermore, a screw hole is opened at the end of the roller 211, and the stopper 213 is connected to the screw hole at the end of the roller by a locking bolt 214. When the GIL cylinder moves into place in the Y direction, the locking bolt 214 is tightened, and the roller 211 cannot rotate, thereby fixing the position of the GIL cylinder in the Y direction.

[0045] In this embodiment, the rotating device 22 includes a handwheel 221, a push rod 222, a pressure block 223, a thrust bearing 224, a connecting shaft 225, a connecting plate 226, a bearing 227, and a sleeve 228. The connecting plate 226 is connected to the pad 215 of the supporting device 21. The pressure block 223 is set in a "concave" shape, and its lower half is connected to the connecting plate 226. A threaded through hole is opened in the middle position of the upper half of the pressure block 233. The surface of the push rod 222 is provided with a thread passing through the middle threaded hole of the pressure block 223. One end of the push rod 222 is connected to the handwheel 221. Further, the outer surface of the handwheel 221 needs to be knurled to increase the friction. The other end of the push rod 222 is connected to the connecting shaft 225. The lower side of the connecting shaft 225 is close to the connecting plate 226, which can be connected to the connecting shaft. The upper surface of the connecting plate 226 slides, and bearings 227 are provided at both ends of the connecting shaft 225. The bearings 227 themselves can rotate, and the outer ring of the bearing 227 is provided with a sleeve 228, and the sleeve 228 is made of soft materials such as nylon. A thrust bearing 224 is provided at the contact point between the connecting shaft 225 and the push rod 222. By turning the hand wheel 221, since there is a threaded transmission between the push rod 222 and the pressure block 223, the push rod 222 can be telescopically moved along the axial direction. At the same time, the symmetrically arranged hand wheel 221 can be rotated to make the bearings 227 move toward each other, and then the GIL cylinder body can be slightly lifted up and away from the supporting device 21. The GIL cylinder body can rotate around its own axis under the support of the bearing 227, which is convenient for adjusting the rotation angle when the GIL cylinder flange 41 is docked.

[0046] In this embodiment, the sliding device 3 includes a slide rail 31, a slider 32, and a limit block 33. The slide rail 31 is connected to the fork of the lifting device 1 at the bottom and is connected to the slider 32 at the top. The slider 32 is connected to the support device pad 215, which can enable the adjustment frame 1 to slide on the slide rail 31. The limit block 33 is set at the end of the slide rail 31. The limit block 33 can limit the sliding limit of the adjustment frame 2 to avoid safety problems such as rollover of the installation vehicle due to excessive sliding.

[0047] like Figure 4 As shown, the method of using the present invention is: use at least one docking vehicle, and consider using two or more docking vehicles at the same time according to the length of the GIL cylinder. First, place the GIL busbar 4 on the adjustment frame 2, push the lifting device 1 to the specified docking position, adjust the center line of the GIL busbar 4 to a horizontal position through the lifting device 1, and then adjust the GIL busbar 4 to be coaxial with the busbar to be docked through the sliding device 3. After the coaxial arrangement, the GIL busbar 4 can move left and right along the axial direction on the adjustment frame 1, so that the GIL conductor contact 42 and the GIL conductor contact seat (not shown in the figure) are docked. When the GIL cylinder flange 41 needs to be rotated during the docking process, the GIL busbar 4 can be slightly lifted up by the rotating device 22, and the GIL busbar 4 can rotate around its own axis to finally complete the docking of the two busbars.

[0048] The GIL on-site cylinder docking vehicle of the present technical solution can significantly improve the quality and efficiency of GIL busbar assembly, greatly improve the stability and balance of the docking process, and two or more trolleys can be used in combination to install longer cylinders. The installation height of the GIL cylinder is adjusted by the adjustment frame and the lifting device that drives the adjustment frame to rise and fall, and the GIL cylinder is adjusted perpendicular to the cylinder axis direction (X direction) in the plane by the sliding device. The GIL cylinder is placed on the roller of the adjustment frame and the cylinder moves in the plane along the cylinder axial direction (Y direction) through rolling transmission. In addition, after the GIL cylinder is adjusted in the horizontal and vertical space positions, the rotating device can also realize the rotation of the cylinder around its own axis, which is convenient for adjusting the rotation angle when the cylinder flange is docked. Compared with the existing lifting technology, the GIL on-site cylinder docking vehicle has the advantages of simple operation, flexible mobility, high efficiency and reliability. It can adjust the GIL cylinder in four directions in a small space. It is particularly suitable for installing GIL cylinders in tunnels. It saves manpower and material resources while improving the installation quality. It also has a low production cost and has a strong value for promotion and application.

[0049] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
