Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary equipment for substation construction, and in particular to a lifting vehicle suitable for temporary construction within a substation. Background Technology
[0002] In substation construction and maintenance, there is a wide demand for working at heights, involving multiple scenarios such as equipment installation, maintenance, and testing. To address the challenges of safe operation in high-voltage environments, existing technologies typically employ an insulated lifting platform solution, combining a scissor lift with an insulated work platform.
[0003] Currently, the workbench panels of insulated work platforms are typically exposed in direct outdoor environments. When the insulated lifting platform is not in use, prolonged exposure to external factors such as ultraviolet radiation, temperature differences, and humidity will accelerate the aging of the insulation materials, leading to a decline in their performance and increasing the risk of high-voltage breakdown. Utility Model Content
[0004] Therefore, it is necessary to provide a lifting vehicle suitable for temporary construction within substations to address the problem that the work platform panels of existing insulated lifting platforms are easily affected by environmental factors when exposed outdoors, leading to aging of insulation materials and increasing the risk of high-voltage breakdown.
[0005] A lifting vehicle suitable for temporary construction within a substation includes: a scissor lift and an insulated platform, wherein the top of the scissor lift is equipped with a safety fence.
[0006] In one embodiment, the insulating platform includes two slide rails fixedly connected to the top of the scissor lift, a slide rod slidably connected between the two slide rails, a pad fixedly connected to the surface of the slide rod, and an insulating pad heat-fused to the top of the pad.
[0007] In one embodiment, the pad has a mounting cavity on its side away from the slide rod, and a positioning pin is slidably connected inside the mounting cavity. One end of the positioning pin passes through the mounting cavity and is inserted into one of the slide rails.
[0008] In one embodiment, the positioning pin is U-shaped, and the corners of the positioning pin are rounded.
[0009] In one embodiment, the maximum length by which the locating pin can move horizontally within the mounting cavity is greater than the depth to which the locating pin penetrates into the slide rail.
[0010] In one embodiment, one end of one of the slide rails has two locking holes, and one end of the positioning pin is inserted into one of the locking holes.
[0011] In one embodiment, the surface of the slide bar is rotatably connected to two rollers, and the two rollers are respectively rotatably connected to the interior of two slide rails.
[0012] In one embodiment, the diameter of the roller is the same as the height of the inner side of the slide rail.
[0013] In one embodiment, the bottom of the pad is coated with a protective coating. Beneficial effects
[0014] 1. The above-mentioned hoisting vehicle, applicable to temporary construction within substations, achieves dual protection for the insulating platform through the linkage design of the slide rail, slide rod, and rotatable pad, combined with the insertion structure of the positioning pin and locking hole: In the working state, the positioning pin inserted into the slide rail can prevent the pad from tilting up, ensuring the stability of the insulating pad; in the non-working state, by flipping the pad, it forms a closed structure with the top plate of the scissor lift, effectively isolating the insulating pad from the effects of ultraviolet rays, temperature differences, and humidity, and significantly delaying the aging of the insulation material.
[0015] 2. The mechanical structure of U-shaped positioning pins and rollers enables the insulating platform to be quickly switched: the rounded corner design and horizontal movement margin of the positioning pins allow for unlocking with one hand, and the equal height matching of the rollers and slide rails reduces rotational resistance. Workers can switch the pad from the horizontal working position to the vertical storage position without tools, which not only ensures the insulation reliability of high-voltage operations, but also improves the equipment storage efficiency.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0026] The following is combined with Figure 1 - Figure 6 This invention describes a lifting vehicle suitable for temporary construction within a substation.
[0027] In one embodiment, a lifting vehicle suitable for temporary construction within a substation includes: a scissor lift 100 and an insulated platform 300, wherein a safety fence 200 is installed on the top of the scissor lift 100.
[0028] The scissor lift 100 can be the Terex Genie GS-3390RT scissor lift aerial work platform, which specifically includes the following structure:
[0029] Base frame: Welded from high-strength steel, equipped with anti-slip pads and lockable casters, with an integrated hydraulic pump station at the bottom.
[0030] Scissor lift assembly: A multi-layered, cross-hinged steel arm that achieves lifting and lowering via hydraulic cylinder extension and retraction.
[0031] Hydraulic system: The hydraulic pump is driven by an electric motor, and the movement of the oil cylinder is controlled by a solenoid valve. It is equipped with an emergency manual pressure relief valve.
[0032] Control box: splash-proof design, includes lifting and emergency stop button, some models support wireless remote control.
[0033] The Safety Fence 200 includes 1.1-meter-high GFRP railings with a central crossbar and a foldable design for easy transport.
[0034] The operating procedure for this scissor lift is as follows: When using the scissor lift 100 for substation construction, first, secure the lockable casters of the base frame to a flat surface, ensuring the anti-slip pads are in contact. Start the hydraulic system's motor-driven hydraulic pump, and operate the solenoid valve via the lifting button on the control box or wireless remote control to smoothly extend the multi-layer steel arms of the scissor lift assembly through the hydraulic cylinders, raising the insulated platform 300 to the working height. Before operation, check that the 1.1-meter-high GFRP railing and middle crossbar of the safety fence 200 are securely locked, and confirm that the folded parts are fully extended. During construction, use the emergency stop button on the control box or the emergency manual pressure relief valve to handle any emergencies. After the operation is completed, retract the scissor lift assembly, fold the safety fence 200, unlock the casters, and move it out of the work position. Throughout the entire process, ensure that the insulated platform 300 is undamaged and that the hydraulic pump station operates normally.
[0035] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the insulating platform 300 includes two slide rails 310, which are fixedly connected to the top of the scissor lift 100. A slide rod 320 is slidably connected between the two slide rails 310. A pad 330 is fixedly connected to the surface of the slide rod 320, and an insulating pad 340 is heat-fused to the top of the pad 330. A mounting cavity 331 is formed on the side of the pad 330 away from the slide rod 320, and a positioning pin 350 is slidably connected inside the mounting cavity 331. One end of the positioning pin 350 extends through the mounting cavity 331 and is inserted into one of the slide rails 310. When the positioning pin 350 is inserted into the corresponding slide rail 310, the slide rail 310 can prevent the pad 330 from tilting up through the positioning pin 350, ensuring that the worker stands stably on the insulating pad 340. The positioning pin 350 is U-shaped, and the edges of the positioning pin 350 are rounded. The worker can pull and rotate the pad 330 through the positioning pin 350, which can effectively reduce the worker's adjustment of the pad 330. The difficulty level is 0, making it easy to adjust. The maximum horizontal movement length of the positioning pin 350 inside the mounting cavity 331 is greater than the depth of the positioning pin 350 penetrating into the slide rail 310. This ensures that the positioning pin 350 can be completely disengaged from the slide rail 310, allowing the operator to effectively adjust the position of the pad 330 and which side faces upwards. One end of one of the slide rails 310 has two locking holes 311. One end of the positioning pin 350 is inserted into one of the locking holes 311. The locking hole 311 can lock the position of the pad 330 through the positioning pin 350, further improving the stability of the pad 330 after adjustment. The surface of the slide rod 320 is rotatably connected to two rollers 360. The two rollers 360 are rotatably connected to the inside of the two slide rails 310 respectively. The diameter of the rollers 360 is the same as the height of the inner side of the slide rail 310. This reduces the burden on the operator to rotate the pad 330, making the adjustment operation easier.
[0036] The bottom of the pad 330 is coated with a protective coating 370, which can be a water-based acrylic polyurethane composite paint. This water-based acrylic polyurethane composite paint is an environmentally friendly, high-performance coating that combines the weather resistance of acrylic with the abrasion resistance of polyurethane. Using water as a solvent, it features low VOCs and no irritating odor, making it suitable for both indoor and outdoor application. Its core advantages include excellent rust prevention, moisture resistance, mildew prevention, and UV resistance. The paint film has high hardness and good flexibility, adapting to the thermal expansion and contraction of the substrate, and dries quickly. It can be sprayed, brushed, or rolled, and is widely applicable to substrates such as metal, wood, and plastic. A specific brand could be Three Trees water-based metal protective paint. During application, proper substrate preparation (such as rust removal and sanding) and the use of a suitable primer are necessary to ensure optimal protection. Compared to oil-based paints, water-based products are more environmentally friendly, dry faster, and have longer-lasting weather resistance, making them an ideal choice that balances performance and environmental friendliness.
[0037] Working principle: After the insulating pad 340 is finished using, the user first removes it from the slide rail 310 corresponding to the positioning pin 350, so that the pad 330 is no longer obstructed. Then, the user drives the pad 330 to rotate upward along the slide rod 320 through the positioning pin 350. When the pad 330 is rotated to a vertical position, the pad 330 drives the slide rod 320 to move horizontally inside the slide rail 310. When the slide rod 320 abuts against the other vertical inner wall of the slide rail 310, the pad 330 is rotated to a horizontal position. At this time, the insulating pad 340 is covered by the top plate of the scissor lift 100 and the pad 330, which can effectively reduce the probability of the insulating pad 340 aging and being damaged due to external factors.
[0038] It should be noted that the scissor lift 100 mentioned above is a device with relatively mature existing technology. The specific model can be selected according to actual needs. In addition, the scissor lift 100 is powered by a built-in power supply, which will not be elaborated here.
[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
