Description

Technical Field

[0001] This invention relates to tractor vehicles, and more particularly to a GIS equipment tractor vehicle with a lifting mechanism. Background Technology

[0002] GIS equipment is short for gas-insulated fully enclosed combined electrical equipment, which is mainly used in high-voltage, ultra-high-voltage, and extra-high-voltage fields and is an important piece of equipment in power systems. Because GIS equipment is a primary device composed of several organically combined modules, it has high requirements for positioning accuracy and docking technology. In addition, GIS equipment is very heavy, and some GIS equipment is installed indoors, where GIS rooms are often space-constrained, resulting in slow installation progress and low efficiency.

[0003] Currently, indoor transportation generally includes the following two types: 1. Gantry cranes, such as the assembled indoor GIS transportation and installation equipment and its usage method disclosed in patent application number CN201910969547.5, which includes a load-bearing mechanism for hoisting GIS equipment, a lifting mechanism for supporting the load-bearing mechanism, a traveling trolley for driving the lifting mechanism, and a traveling mechanism used in conjunction with the traveling trolley. The two ends of the support mechanism are fixed to the traveling trolley through the lifting mechanism to form a gantry frame, and the traveling trolley is installed on the traveling mechanism; 2. Handling trolleys, such as those in application number CN201920330. Patent 286.8 discloses a substation GIS installation trolley, including a trolley chassis, load-bearing columns, load-bearing slope protection, a front pull rope fulcrum, casters, fixing rope holes, fixing ropes, GIS equipment components, and a front pull rope. Two load-bearing columns are welded to the upper surface of the trolley chassis, and the two load-bearing columns are parallel to each other and perpendicular to the trolley chassis. The front pull rope fulcrum is welded to one end of a load-bearing column, and the front pull rope fulcrum is parallel to the trolley chassis. The front pull rope is tied to the front pull rope fulcrum. The load-bearing slope protection is welded to the upper part of the load-bearing columns.

[0004] Using a gantry crane requires pre-installation of the track and the crane itself indoors, and also necessitates the use of an electric hoist for lifting. This not only results in a complex structure and high cost, but also severely limits the transport trajectory due to the pre-set track, and introduces swaying during transport, posing a high risk. While using a transport trolley offers the advantage of a controllable transport trajectory, securing and unloading the GIS equipment using a transport trolley presents a significant challenge. The aforementioned patent describes an extremely complex securing structure, requiring substantial time for securing and disassembling before and after transport. Furthermore, unloading necessitates the use of lifting equipment, leading to high overall equipment complexity and correspondingly increased costs. Summary of the Invention

[0005] In view of the shortcomings of existing GIS equipment transportation devices, such as complex structure, insufficient flexibility during transportation, and inconvenience in unloading, this invention provides a GIS equipment tractor with a lifting mechanism.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a GIS equipment tractor with a lifting mechanism, comprising a tractor and a lifting mechanism, wherein the tractor is provided with a pressure clamping mechanism, the pressure clamping mechanism having clamping plates extending to both sides of the pressure surface of the tractor, and T-shaped hooks provided on the clamping plates; the lifting mechanism comprises: a supporting base plate, the bottom of which is provided with wheel seats; two lifting cylinders, which are provided and symmetrically arranged on the top surface of the supporting base plate; universal wheels, which are fixed to the bottom of the wheel seats and each wheel seat is provided with at least two universal wheels; two connecting arms, which are provided and rotatably connected to the two lifting cylinders respectively, the connecting arms having racetrack-shaped hanging holes for hanging on the hooks, and a release port being provided on the bottom center side of the hanging holes; a top plate, the bottom of which is provided with a slide rail, the output end of the lifting cylinder being fixed to the bottom of the top plate; and a carriage, which is slidably arranged on the slide rail, and has an L-shaped plate for lifting. During transportation, two sets of the device are required, and they are respectively installed at both ends of the GIS equipment base frame. During towing, both sets can be towed together or one set can be towed.

[0007] Preferably, the top surface of the horizontal section of the L-shaped plate has a horizontal plane and an unloading ramp, with the thickness of the unloading ramp gradually decreasing from near the vertical section of the L-shaped plate to away from it. During unloading, the L-shaped plate is lifted by a lifting cylinder to raise the GIS equipment, releasing the clamp on the GIS equipment and allowing it to detach from the traction trolley. Then, the traction trolley is moved to disengage the connecting arm from the latch. The traction trolley is then moved to the outside, and the connecting arm is hung upside down on the latch. The lifting mechanism is pulled outward by the traction trolley, causing the GIS equipment to switch from the horizontal plane against the L-shaped plate to the unloading ramp against the L-shaped plate. The equipment is then slowly pulled outward to slide to the ground, thus completing the unloading process.

[0008] Specifically, the lifting cylinder has a cylindrical mounting rod on its side wall, and a connecting arm is sleeved on the mounting rod. The connecting arm can slide along the mounting rod and rotate around it. The end of the mounting rod has a limiting end cap. When the clamping plate is pressed to tighten the GIS equipment, the connecting arm slides automatically to adapt to the position.

[0009] Preferably, a lifting pump is located in the middle of the support base plate, and the lifting pump is connected to the lifting cylinder via a flexible pipe. In actual use, an external pump body can also be used in conjunction with the lifting cylinder.

[0010] Preferably, the pressure clamping mechanism includes: a base fixed inside the traction trolley, comprising two sets of symmetrically positioned limiting seats and several limiting posts; a pressure frame including a pressure plate, a left lifting post and a right lifting post disposed at the bottom of the pressure plate, and an extension post disposed at the bottom of the pressure plate, the extension post extending into the limiting post and sliding vertically with the limiting post, the left and right lifting posts being symmetrically positioned and having an upper pressing slope at their bottom; a sliding frame, comprising multiple symmetrically positioned and horizontally sliding inside the traction trolley, which is limited by the limiting seats and slides only in the left and right directions, one end of which has a lower pressing slope that cooperates with the upper pressing slope, and the other end extending vertically upward to form a pressing part for clamping the GIS equipment; and a reset device, comprising two symmetrically positioned devices located between the sliding frames and the limiting seats, which reset the sliding frames after the GIS equipment is removed from the pressure plate. When the GIS equipment presses down on the pressure frame, the pressing slope between the pressure frame and the sliding frame causes the two sliding frames to move inward, thereby clamping the GIS equipment.

[0011] Preferably, the pressure plate has N sets of left and right lifting columns at its bottom, and N sliding frames are symmetrically arranged on both sides. The pressure plate has N notches on both sides, and the pressing parts of the sliding frames extend from these notches and can slide along them. Each sliding frame has a clamping plate at its pressing part that connects the pressing parts on the same side. In this design, multiple sliding frames are connected together by clamping plates to form a single unit, improving the overall stability of the sliding frame.

[0012] Preferably, a plurality of rotatable spheres are embedded on the top surface of the pressure plate, and the top surfaces of the spheres are all at the same height and are higher than the top surface of the pressure plate. When the GIS equipment presses down on the pressure plate, the spheres support the GIS equipment. If the GIS equipment is biased to one side of the clamping plate, it will automatically adjust to the center position on the spheres.

[0013] Specifically, the traction trolley includes a housing, inside which a partition divides the internal cavity into an upper cavity and a lower cavity. The pressure clamping mechanism is located in the upper cavity. The upper and lower cavities are used to house and install the drive mechanism and the pressure clamping mechanism.

[0014] Specifically, the lower cavity is equipped with a drive mechanism, which includes a walking wheel set, a drive wheel set, and a ternary lithium battery. The walking wheel set and the drive wheel set each include two walking wheels and two drive wheels. The two drive wheels are mounted on two axles, and the two axles are rotatably mounted in the lower cavity through two bearing seats. The lower cavity is also equipped with two drive motors, which drive the two axles and the drive wheels on the axles to rotate through a set of bevel gears. Each drive motor is powered by a ternary lithium battery.

[0015] Preferably, the bottom of the lower cavity is provided with a removable cover plate, and a controller is provided on the cover plate. The drive motor and the ternary lithium battery are both connected to the controller through connectors.

[0016] Compared with the prior art, the advantages of this invention are as follows: This application uses multiple traction trolleys to transport GIS equipment. During transportation, the pressure clamping mechanism of the traction trolley can clamp the GIS equipment when subjected to downward pressure. During unloading, the L-shaped plate is lifted by the lifting cylinder to lift the GIS equipment, release the clamp on the GIS equipment and allow the GIS equipment to detach from the traction trolley. Then, the traction trolley is moved and the connecting arm is disengaged from the hook. The traction trolley is then moved to the outside and the connecting arm is hung upside down on the hook. The lifting mechanism is pulled outward by the traction trolley to switch the GIS equipment from the horizontal plane against the L-shaped plate to the unloading ramp against the L-shaped plate. The GIS equipment is then slowly pulled outward to slide to the ground, thus completing the unloading. Attached Figure Description

[0029] Example

[0030] A GIS equipment tractor with a lifting mechanism, such as Figure 1-3As shown, the device includes a traction trolley and a lifting mechanism 30. The traction trolley is equipped with a pressure clamping mechanism, which has clamping plates 203 extending to both sides of the pressure surface of the traction trolley. T-shaped hooks 2031 are provided on the clamping plates 203. The lifting mechanism 30 includes: a support base plate 305, the bottom of which is provided with wheel seats 306; two lifting cylinders 308, which are symmetrically arranged on the top surface of the support base plate 305; and casters 307, which are fixed to the bottom of the wheel seats 306, and each wheel seat 306 has at least one caster. Two casters 307; two connecting arms 301, each rotatably connected to two lifting cylinders 308, the connecting arms 301 having racetrack-shaped hanging holes 3011 for hanging on hooks 2031, the bottom center of the hanging holes 3011 having a release port 30111; a top plate 304 having a slide rail 302 at its bottom, the output end of the lifting cylinders 308 being fixed to the bottom of the top plate 304; a carriage 3031, slidably mounted on the slide rail 302, having an L-shaped plate 303 for lifting. During transportation, two sets of this device are required, each installed at one end of the base frame of the GIS equipment 10. During traction, both sets can be used for traction, or only one set can be used. During transport, the device can be supported by the top plate 304 and the traction trolley. In this case, the length of the hanging hole 3011 needs to be extended to allow for lowering the lifting mechanism 30 during unloading and adjusting its position so that the L-shaped plate 303 can be hung at the end of the GIS equipment 10. Alternatively, the L-shaped plate 303 and the traction trolley can be used for support, in which case the position of the lifting mechanism 30 does not need to be adjusted. In this solution, the lifting cylinder 308 can be replaced with a screw jack, driven by a horizontal screw to ensure synchronous lifting on both sides.

[0031] like Figure 3 As shown, the top surface of the horizontal section of the L-shaped plate 303 has a horizontal plane and an unloading ramp. The thickness of the unloading ramp gradually decreases from the vertical section near the L-shaped plate 303 to the section away from the vertical section of the L-shaped plate 303. During unloading, the L-shaped plate 303 is lifted by the lifting cylinder 308 to lift the GIS equipment 10, releasing the clamp on the GIS equipment 10 and allowing the GIS equipment 10 to detach from the traction trolley. Then, the traction trolley is moved and the connecting arm 301 is detached from the latch 2031. The traction trolley is then moved to the outside and the connecting arm 301 is hung upside down on the latch 2031. The lifting mechanism 30 is pulled outward by the traction trolley, causing the GIS equipment 10 to switch from the horizontal plane against the L-shaped plate 303 to the unloading ramp against the L-shaped plate 303. The GIS equipment 10 is then slowly pulled outward to slide to the ground, thus completing the unloading.

[0032] like Figure 9As shown, the lifting cylinder 308 has a cylindrical mounting rod 309 on its side wall, and a connecting arm 301 is sleeved on the mounting rod 309. The connecting arm 301 can slide along the mounting rod 309 and rotate around the mounting rod 309. The end of the mounting rod 309 is provided with a limiting end cap. When the clamping plate 203 is pressed and clamps the GIS equipment 10, the connecting arm 301 slides automatically to adapt to the position.

[0033] Preferably, a lifting pump is located in the middle of the support base plate 305, and the lifting pump is connected to the lifting cylinder 308 via a flexible pipe. In actual use, an external pump body can also be used in conjunction with the lifting cylinder 308. The flexible pipe is a two-way pipe that controls the movement of the lifting cylinders 308 on both sides simultaneously to ensure that both sides rise and fall at the same time.

[0034] like Figure 4-6 As shown, the pressure clamping mechanism includes: a base body, which is fixed inside the traction trolley, including two sets of left-right symmetrical limiting seats 205 and several limiting posts 206; a pressure frame, which includes a pressure plate 201, a left lifting post and a right lifting post 2012 disposed at the bottom of the pressure plate 201, and an insert post 2013 disposed at the bottom of the pressure plate 201. The insert post 2013 extends into the limiting post 206 and slides vertically with the limiting post 206. The left lifting post and the right lifting post 2012 are left-right symmetrical, and both have an upper compression slope 201 at their bottom. 21; Multiple sliding frames 204 are symmetrically arranged on the left and right sides and slide horizontally within the traction trolley. They are limited by limiting seats 205 and slide only in the left and right directions. One end of the sliding frame has a lower pressing slope 2041 that cooperates with the upper pressing slope 20121, and the other end extends vertically upward to form a pressing part for pressing the GIS equipment 10. Two reset devices are symmetrically arranged on the left and right sides, located between the sliding frames 204 and the limiting seats 205. After the GIS equipment 10 is removed from the pressure plate 201, the sliding frames 204 are reset. When the GIS equipment 10 presses down on the pressure frame, the pressing slope between the pressure frame and the sliding frames 204 causes the two sliding frames 204 to move inward, thereby clamping the GIS equipment 10. The limiting seat 205 has a downward opening and is detachably installed within the traction trolley. The reset device is a reset spring 207. When the GIS device 10 is placed on the pressure plate 201, the pressure plate 201 moves downward under pressure, and the lifting columns on both sides move downward accordingly. Under the action of the squeezing inclined surface, the sliding frames 204 on both sides move closer to the middle, thereby clamping the GIS device 10. In this solution, the limiting column 206 and the extending column 2013 are both provided with four in a rectangular array.

[0035] like Figure 4-6As shown, N sets of left and right lifting columns 2012 are provided at the bottom of the pressure plate 201, and N sliding frames 204 are symmetrically arranged on the left and right sides. N notches 2011 are provided on both sides of the pressure plate 201. The pressing part of the sliding frame 204 extends out from the notch 2011 and can slide along each notch 2011. Each sliding frame 204 has a clamping plate 203 at its pressing part, connecting the pressing parts on the same side. Preferably, N = 3. In this design, multiple sliding frames 204 are provided and connected together by clamping plates 203 to form a whole, improving the stability of the entire sliding frame 204.

[0036] like Figure 4 As shown, a plurality of rotatable spheres 202 are embedded on the top surface of the pressure plate 201. The top surfaces of the spheres 202 are all at the same height and are higher than the top surface of the pressure plate 201. When the GIS equipment 10 presses down on the pressure plate 201, the spheres 202 support the GIS equipment 10. If the GIS equipment 10 is biased towards one side of the clamping plate 203, it will automatically adjust to the center position on the spheres 202.

[0037] like Figure 6-7 As shown, the traction trolley includes a housing 200, inside which is a partition 2001, dividing the inner cavity of the housing 200 into an upper cavity and a lower cavity. The pressure clamping mechanism is located in the upper cavity. The upper and lower cavities are used to house and install the drive mechanism and the pressure clamping mechanism.

[0038] like Figure 7 As shown, a drive mechanism is provided in the lower cavity. The drive mechanism includes a walking wheel set, a drive wheel set, and a ternary lithium battery. The walking wheel set and the drive wheel set each include two walking wheels 208 and two drive wheels 211. The two drive wheels 211 are mounted on two axles 210. The two axles 210 are rotatably mounted in the lower cavity through two bearing seats. The lower cavity also provides two drive motors 209. The two drive motors 209 drive the two axles 210 and the drive wheels 211 on the axles 210 to rotate through a set of bevel gears. Each drive motor 209 is powered by a ternary lithium battery.

[0039] Preferably, the bottom of the lower cavity is provided with a removable cover plate, on which a controller is installed. The drive motor 209 and the ternary lithium battery are both connected to the controller via connectors. The cover plate has holes for the drive wheel 211 and the walking wheel 208 to extend out, and the cover plate is used to protect the internal drive mechanism.

[0040] The foregoing has described a GIS equipment tractor with a lifting mechanism provided by the present invention. Specific examples have been used to illustrate the principles and implementation methods of the invention. The descriptions of the embodiments above are merely for the purpose of helping to understand the invention and its core ideas. It should be noted that those skilled in the art can make various improvements and modifications to the invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
