Description

Technical Field

[0001] This utility model belongs to the field of lifting equipment technology, and mainly relates to a lifting platform for indoor substation equipment installation. Background Technology

[0002] The development of mechanization at substation construction sites remains insufficient, with some tasks still relying on manual labor. Many types of construction machinery are not yet used in power transmission and transformation projects, and there is a lack of machinery suitable for certain operations within these projects. In the substation installation field, outdoor substation machinery is frequently used. However, large, traditional installation and transportation machinery cannot be used indoors, and existing small-scale installation and transportation machinery is not fully compatible with substation installation sites, resulting in limited adoption and a low level of mechanization in indoor substation installation.

[0003] Therefore, to improve the mechanization level of substation installation projects, it is necessary to develop a transportation and installation machine that is suitable for substation installation sites and can handle equipment and materials indoors.

[0004] Meanwhile, at the junction of the indoor and outdoor parts of the substation, there are usually obstacles such as steps. These obstacles are also key factors affecting mechanical handling equipment. The height of the steps is usually 1.2m-1.8m. To compensate for this height, the current common practice is to lay sleepers on the ground. After the height of the sleepers is level with the height of the steps, steel plates are laid on top of the sleepers.

[0005] This method has the following disadvantages:

[0006] 1. It usually takes 4 to 5 people to set up for about 2 to 4 hours, which consumes labor and prolongs the operation time.

[0007] 2. Sleepers are often consumables with low recycling rates.

[0008] 3. The platform is not neat enough. The top is often made of multiple steel plates spliced ​​together, resulting in an uneven surface.

[0009] Despite the aforementioned drawbacks, this platform remains the primary method for constructing indoor substations due to its ease of setup.

[0010] However, in the current context of vigorously developing mechanized construction, this type of platform is difficult to adapt to the requirements of the current mechanized construction development. Compared with manual handling, construction machinery has higher requirements for ground flatness, and the sleeper steel plate platform is difficult to be completely level with the indoor ground due to its own height. The height difference between the two affects the normal operation of construction machinery. Utility Model Content

[0011] This utility model provides a lifting platform for indoor substation equipment installation, which solves the problem that the manually constructed platforms in the prior art cannot meet the requirements of mechanized construction.

[0012] To solve the above problems, the present invention adopts the following technical solution:

[0013] A lifting platform for installing equipment in an indoor substation includes a tracked chassis and a lifting platform movably arranged on the tracked chassis in the vertical direction. The tracked chassis is used to move on the ground, and the lifting platform is provided with a telescopic platform in the horizontal direction. The telescopic platform is used to place the equipment to be installed and is used to extend to contact the indoor substation.

[0014] It has the following advantages: the tracked chassis has a large contact area with the ground, which distributes the weight of the equipment and provides better stability. During the lifting process, it can effectively prevent the equipment from shaking and ensure the safety of the operators. At the same time, the lifting platform can be raised and lowered in the vertical direction to be level with the entrance of the indoor substation, ensuring that the equipment can enter the indoor substation smoothly and stably.

[0015] Furthermore, the tracked chassis is provided with multiple support legs on its four sides, which are used to stabilize the tracked chassis.

[0016] It has the following beneficial effects: During the lifting process, multiple outriggers support the ground, ensuring stability during the lifting process.

[0017] Furthermore, each of the outriggers includes a linear drive and a plate connected to the linear drive, the linear drive extending and retracting in the vertical direction to press the plate against the ground.

[0018] It has the following beneficial effects: multiple flat plates press against the ground, ensuring stability during the lifting process.

[0019] Furthermore, the telescopic platform includes a movable seat movably arranged on the lifting platform and a plurality of rollers equally spaced on the movable seat. The movable seat moves horizontally, and the axial extension direction of the rollers is perpendicular to the moving direction of the movable seat.

[0020] It has the following beneficial effects: the mobile base can move the equipment toward the entrance of the indoor substation, and the multiple rollers on the mobile base facilitate the removal of the equipment from the mobile base.

[0021] Furthermore, the front end of the movable seat is provided with a connecting plate, which is used to contact the indoor substation.

[0022] It has the following beneficial effects: the connecting plate can be connected to the door of the indoor substation, making the connection between the mobile base and the door of the indoor substation more stable.

[0023] Furthermore, the lifting platform is provided with guardrails around its perimeter, and the guardrails have openings for the telescopic platform to extend out.

[0024] Furthermore, the tracked chassis is equipped with a scissor-type telescopic mechanism, and the lifting platform is mounted on the scissor-type telescopic mechanism.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] The following describes various non-limiting embodiments of this utility model. Any number of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] like Figure 1 , Figure 2As shown, a lifting platform for installing equipment in an indoor substation includes a tracked chassis 1 and a lifting platform 2 movably arranged on the tracked chassis 1 in a vertical direction. The tracked chassis 1 is used to move on the ground, thereby realizing the movement of the lifting platform. A telescopic platform 3 is movably provided on the lifting platform 2 in a horizontal direction. The telescopic platform 3 is used to place the equipment to be installed. The telescopic platform 3 extends out to contact the indoor substation, and then the equipment can be moved from the telescopic platform 3 into the indoor substation.

[0034] The tracked chassis 1 has a large contact area with the ground, which distributes the weight of the equipment and provides better stability. During the lifting process, it can effectively prevent the equipment from shaking and ensure the safety of the operators. At the same time, the lifting platform 2 can be raised and lowered in the vertical direction to be level with the entrance of the indoor substation, ensuring that the equipment can enter the indoor substation smoothly and stably.

[0035] Meanwhile, the tracked chassis 1 can travel on various complex terrains, such as muddy ground and rugged mountain roads, adapting to different working environments. It can be easily moved to locations requiring high-altitude operations, improving work efficiency. Furthermore, the tracked chassis 1 can typically carry heavy loads and personnel, meeting diverse work needs and also fulfilling its supporting function for substation equipment.

[0036] The tracked chassis 1 has four outriggers along its four edges for stability. During lifting, these outriggers support the ground, ensuring stability. These outriggers can be remotely controlled via a controller to determine their support status. The controller also allows for one-button leveling of the outriggers. Once the lifting platform 2 reaches a preset level, the controller sends a completion signal, such as an indicator light turning green or a short buzzer sounding, to notify the operator that leveling is complete. The number of outriggers can be determined based on actual needs.

[0037] In this embodiment, each outrigger includes a linear drive 5 that extends and retracts vertically, and a flat plate 6 connected to the linear drive 5. The telescopic end of the linear drive 5 faces downward, and the flat plate 6 is arranged on the telescopic end of the linear drive 5. The linear drive 5 extends and retracts vertically to press the flat plate 6 against the ground for support. The multiple flat plates 6 pressing against the ground ensure stability during the lifting process and guarantee the safety of equipment movement.

[0038] In this embodiment, the linear drive component 5 is a hydraulic cylinder.

[0039] In other embodiments, the linear drive 5 is an electric actuator.

[0040] In this embodiment, the telescopic platform 3 includes a movable seat 8 movably arranged on the lifting platform 2 and a plurality of rollers 9 equally spaced on the movable seat 8. The lifting platform 2 is equipped with a hydraulic cylinder, the telescopic end of which is connected to the movable seat 8, thereby driving the movable seat 8 to move horizontally on the lifting platform 2. Each roller 9 is rotatably mounted on the movable seat 8, and the axial extension direction of the roller 9 is perpendicular to the moving direction of the movable seat 8. The movement of the movable seat 8 allows it to carry the equipment towards the entrance of the indoor substation, and the multiple rollers 9 on the movable seat 8 facilitate the removal of the equipment from the movable seat 8.

[0041] The front end of the mobile base 8 is provided with a connecting plate 10, which is used to contact the indoor substation. The connecting plate 10 can be connected to the door of the indoor substation, making the connection between the mobile base 8 and the door of the indoor substation more stable and facilitating the movement of the equipment into the indoor substation.

[0042] The lifting platform 2 is equipped with guardrails 7 around its perimeter, and the guardrails 7 have openings for the extension platform 3 to extend out.

[0043] The tracked chassis 1 is equipped with a scissor telescopic mechanism 4, and the lifting platform 2 is mounted on the scissor telescopic mechanism 4. The scissor telescopic mechanism 4 extends and retracts in the vertical direction to drive the lifting platform 2 to move.

[0044] In other embodiments, a hydraulic cylinder can be used instead of the scissor telescopic mechanism 4. The hydraulic cylinder is arranged on the tracked chassis 1, and the lifting platform 2 is mounted on the telescopic end of the hydraulic cylinder. The hydraulic cylinder directly drives the lifting platform 2 to move up and down in the vertical direction.

[0045] In this embodiment, the tracked chassis 1 includes track wheels and a chassis frame, with the chassis frame mounted on the track wheels, which are used for movement on the ground. Four outriggers are mounted on the chassis frame, and the scissor-type telescopic mechanism 4 is also mounted on the chassis frame.

[0046] The working process of this utility model is as follows:

[0047] The lifting platform described in this embodiment is moved to the side of the indoor substation, with the outriggers supporting the ground. Then, the equipment to be installed is hoisted onto the lifting platform 2 by a crane. The lifting platform 2 is raised to a certain height and level with the entrance of the indoor substation. Then, the moving seat 8 is driven to move, moving the equipment toward the entrance of the indoor substation. Finally, the equipment is removed from the lifting platform 2.
