[0024] Example 1:

[0025] like Figures 1 to 8 As shown, this invention provides a novel intelligent transport and positioning equipment for installing HGIS equipment in confined spaces in substations. The intelligent transport and positioning equipment consists of two parts: a transport vehicle and a positioning platform. The transport vehicle is composed of outriggers 2, a battery compartment 4, a hydraulic pump station 5, an electrical control box 6, a transport vehicle body 11, drive wheels 12, casters 13, a rack 17, a large gear 18, a gear shaft 19, a small gear 20, a medium gear 21, a reduction motor 22, a bearing seat 23, support legs 27, and a telescopic cylinder 28. The transport vehicle body 11 is equipped with a level in both the longitudinal and transverse directions for leveling the vehicle body during equipment installation and positioning. The positioning platform is composed of a safety pin 1, a platform pressure plate 3, a positioning support plate 7, a load-bearing wheel electric cylinder 8, load-bearing wheels 9, a platform track 10, a rack connecting angle steel 16, a claw 24, a locking nut 25, a clamp electric cylinder 26, a load-bearing bracket 31, support rollers 32, and a positioning trailer 33.

[0026] The platform rail 10 is reliably welded to the transport vehicle body 11. The middle part of the transport vehicle body 11 is designed as a sunken structure, and the platform rail 10 is embedded in the sunken structure, which reduces the height of the bearing platform and ensures a safe distance between the HGIS equipment and the overhead energized main pipe during equipment placement. At the same time, the overall center of gravity is lowered, increasing stability. The platform rail 10 has a U-shaped structure with an open upper part. The positioning tray 7 is pressed between the positioning bracket 33 and the platform pressure plate 3, and is fastened with high-strength screws.

[0027] The safety pin 1 is installed between the side lugs of the positioning tray 7 and the positioning bracket 33 and the platform rail 10 to prevent the vehicle body from shaking during travel and transportation, which would cause the support roller 32 on the positioning bracket 33 to slide along the platform rail 10 and damage the pinion 20 and rack 17.

[0028] The bearing seat 23 is fixed on the bottom plate of the trolley body 11, and the two sets of racks 17 are fixed on the bottom of the positioning support plate 7 through the rack connecting angle steel 16. The output shaft of the speed reducer motor 22 is matched with the middle gear 21, the gear shaft 19 is matched with the large gear 18 and the small gear 20, the speed reducer motor 22 drives the middle gear 21 to rotate, and the middle gear 21 drives the large gear 18 to rotate, and the small gear 20 further drives the rack 17 to move horizontally.

[0029] The positioning support bracket 33 is provided with the supporting wheels 32 on both sides, and the supporting wheels 32 roll in the bearing platform track 10, so that the moving resistance is reduced, and the horizontal movement is smooth.

[0030] The clamp electric cylinder 26 is fixed on the positioning support plate 7 through four bolts, and the locking nut 25 is used for locking the clamping jaw 24 on the threaded stud at the upper end of the clamp electric cylinder 26, so that the clamping jaw 24 is prevented from loosening.

The bearing electric cylinder 8 drives the bearing wheel 9 to move up and down to bear the load, and the bearing wheel 9 can roll on the platform 100. Two lifting bearing wheels 9 are arranged at the front end of the positioning support bracket 33.

[0032] The jacking support 29 and the jacking hanging piece 30 can move horizontally on the slide rail beam 15 to adjust the horizontal span to adapt to different workpiece sizes and foundation 100 conditions. The jacking support 29 is vertically aligned with the hydraulic jack 14 and is located on the bearing surface of the hydraulic jack 14, and the platform surface of the jacking hanging piece 30 is clamped in the slot of the HGIS equipment bottom frame.

[0034] To achieve the above object, the intelligent transportation and positioning equipment mainly consists of two parts, namely, a carrier for realizing the transportation function and a positioning support for realizing the positioning function, and a transmitting and receiving device for remote control operation. Most of the actions in the installation, transportation and positioning process are remotely controlled.

The middle part of the carrier body 11 is designed as a sunken structure, and the support track 10 is embedded in the sunken structure, thereby reducing the height of the positioning support, ensuring the safe distance between the HGIS device and the overhead live busbar during the positioning of the device, and lowering the overall gravity center to increase the stability. The support track 10 is of a U-shaped structure with an open upper part, and the positioning support and the support pressing plate 3 are fastened by high-strength screws after being hoisted and positioned.

[0038] As a preferred scheme of the application, the safety bolt 1 is installed between the positioning support and the support track 10 to prevent the carrier body from shaking during the walking and carrying process, thereby preventing the positioning support from sliding and damaging the gear and rack 17. The safety bolt 1 is only opened before the device is positioned, and is inserted again after the positioning support is withdrawn and returned to the original position after the positioning of the device is completed.

[0039] As a preferred scheme of the application, the electric clamp device is arranged on the in-place support platform, aiming to reliably fix the HGIS equipment on the intelligent transportation in-place equipment, and the clamp jaw 24 is driven by a servo electric cylinder.

[0046] As Figure 1 , Figure 2 shown, the platform rail 10 is reliably welded with the trolley body 11. The middle part of the trolley body 11 is designed as a sunken structure, and the platform rail 10 is embedded in the sunken structure, which reduces the height of the bearing platform, ensures the safe distance between the HGIS device and the upper live busbar during the device positioning process, and at the same time, the overall gravity center is lowered, and the stability is increased. The platform rail 10 is a U-shaped structure, the upper part is open, the positioning support plate 7 is tightly pressed between the positioning bracket 33 and the platform pressing plate 3, and high-strength screws are used for fastening.

[0047] As Figure 1 , Figure 2 shown, the safety bolt 1 is installed between the positioning support plate 7, the side ear plate of the positioning bracket 33 and the platform rail 10, which prevents the trolley body from shaking during walking and carrying, causing the supporting wheel 32 on the positioning bracket 33 to slide along the platform rail 10 and damage the pinion 20 and the rack 17.

[0048] As Figure 2 , Figure 3 shown, the bearing seat 23 is fixed on the bottom plate of the trolley body 11.

[0049] As Figure 8 shown, the positioning bracket 33 is provided with supporting wheels 32 on both sides, which roll in the platform rail 10, reducing the moving resistance and making the translation smooth.

[0050] As Figure 1 , Figure 4 shown, the electric clamp is composed of a claw 24, a locking nut 25 and a clamp electric cylinder 26. The clamp electric cylinder 26 is fixed on the positioning support plate 7 by four bolts, and the locking nut 25 locks the claw 24 on the stud at the upper end of the clamp electric cylinder 26 to prevent loosening. During operation, four groups of clamp electric cylinders 26 drive four groups of claws 24 to move up and down and clamp the HGIS device, so that it is reliably fixed. The clamping force of the claw 24 is accurately adjustable, and the present application adopts four electric clamps fixed on the front, rear, left and right of the positioning bracket 33 to ensure that the HGIS device is firmly and reliably positioned on the positioning support plate 7.

The bearing electric cylinder 8 drives the bearing wheel 9 to make lifting movement to bear the load, and enables the bearing wheel 9 to roll on the platform of the foundation 100. The application ensures the stability of the structure of the in-place bracket 33, avoids instability and even bending deformation of the in-place bracket 33 when the in-place bracket 33 is cantilevered.

[0052] As shown in the drawings, Figure 6 , Figure 8 The jacking support 29, the slide rail beam 15 and the jacking hanging piece 30 jointly constitute a jacking cross beam which is used in cooperation with the hydraulic jack 14.

[0053] As shown in the drawings, Figure 1 , Figure 7 The leg 2, the foot 27 and the telescopic oil cylinder 28 jointly constitute a hydraulic leg structure. One end of the leg 2 is connected to the lower end of the side double lug plate structure of the carrier body 11 by a pin structure.
