Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment installation, and particularly relates to a novel lifting platform for electrical equipment installation. Background Art

[0002] In the current process of electrical engineering construction and maintenance, the lifting platform, as an important auxiliary equipment, plays a crucial role. Although the traditional lifting platform meets the installation and maintenance needs of electrical equipment to a certain extent, there are still many deficiencies in the actual use process, such as poor stability, complex operation, inconvenient adjustment, etc. These problems not only affect the work efficiency but also pose potential safety hazards to the staff.

[0003] Specifically, (1) The traditional lifting platform has significant deficiencies in terms of stability: Since the installation and maintenance of electrical equipment often need to be carried out at high altitudes, the stability of the lifting platform is directly related to the safety of the staff; however, the traditional lifting platform often adopts a simple support structure and cannot provide sufficient stability. (2) The operation of the traditional lifting platform is complex and the adjustment is inconvenient: During the installation and maintenance of electrical equipment, the height of the lifting platform needs to be adjusted frequently; however, the traditional lifting platform often adopts a manual adjustment method, which is not only cumbersome to operate but also has low adjustment accuracy and is difficult to meet the refined work requirements. At the same time, since the adjustment process requires manual operation, it also increases the labor intensity and safety risks of the staff. (3) The expandability of the traditional lifting platform is poor: During the installation and maintenance of electrical equipment, it is often necessary to carry equipment of different sizes and weights, so the expandability of the lifting platform is particularly important; however, the traditional lifting platform often adopts a fixed size and structure design and cannot meet the needs of different equipment and different working scenarios, thus limiting its application range.

[0004] Therefore, there is an urgent need to design a novel lifting platform for electrical equipment installation to solve the problems of poor stability, complex operation, inconvenient adjustment, and poor expandability existing in the traditional lifting platform. Summary of the Utility Model

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a novel lifting platform for electrical equipment installation.

Both sides of the chassis are fixedly connected with a plurality of support components. One end of the chassis is fixedly connected with a push rod. Inside the chassis, a first platform and a second platform are fixedly connected. Above the chassis, there is a support platform, which is connected to the chassis through a scissor lifting unit. The support platform has a cavity inside, and an expansion plate is slidably connected inside the cavity. At the top of the support platform, a first fence is fixedly connected. At the top of one end of the expansion plate, a second fence is fixedly connected.

[0007] Specifically, a plurality of movable casters are fixedly connected to the bottom of the chassis, and locking parts are provided on the movable casters. The number of the movable casters is four, and they are distributed in a rectangular shape at the four corners of the bottom of the chassis.

[0008] Specifically, the support component includes a fixed plate fixedly connected to the chassis. A screw rod is penetrated through the fixed plate and is threadedly connected thereto. The top end of the screw rod is fixedly connected with a rotating handle, and the bottom end of the screw rod is rotatably connected with a support bottom plate through a bearing.

[0009] Specifically, the scissor lifting unit includes two scissor bracket assemblies both connected to the chassis and the support platform. Each of the two scissor bracket assemblies includes a first strut and a second strut, and the first strut and the second strut are hinged. The hinged part of the first strut and the second strut is connected through a rotating shaft rod. The top ends of both first struts are hinged with a first connecting seat fixedly connected to the support platform. The bottom ends of both first struts are rotatably connected with first rollers, and a first slide rail for the first rollers to slide is fixedly connected to the chassis. The top ends of both second struts are rotatably connected with second rollers, and a second slide rail for the second rollers to slide is fixedly connected to the bottom of the support platform. The bottom ends of both second struts are hinged with a second connecting seat fixedly connected to the chassis. Both first struts are fixedly connected through a first connecting rod.

[0010] Specifically, a first motor is fixedly connected to the first platform. A first lead screw is provided at the output end of the first motor. A lead screw sleeve is threadedly connected to the first lead screw. The lead screw sleeve and the first connecting rod are fixedly connected through a vertical rod.

[0011] Specifically, a bearing seat for rotatably connecting with the first lead screw is fixedly connected to the second platform. Both second struts are fixedly connected through a second connecting rod.

[0014] The utility model has the following beneficial effects:

[0015] The novel lifting platform for electrical equipment installation designed by the utility model can provide stable support in different terrains and working environments by arranging a plurality of support components on both sides of the chassis and cooperating with the design of movable casters and locking parts; through the design of the screw rod and the rotating handle of the support component, the support platform can be finely adjusted according to actual needs, further enhancing its stability and ensuring the safety of the staff during high-altitude operations.

[0016] The novel lifting platform for electrical equipment installation designed by the utility model adopts a scissor lifting unit and is driven by a first motor to realize the automatic lifting adjustment of the support platform.

[0031] AsFigure 7 As shown in the figure, in the present utility model, the support assembly 2 includes a fixed plate 2.1 fixedly connected to the chassis 1.

The bottom end of the screw rod 2.2 is rotatably connected to a support bottom plate 2.5 through a bearing 2.4, which can provide stable support under different terrains and working environments and improve the stability.

[0032] As Figure 5 and Figure 6 As shown in the figure, in the present utility model, the scissor lift unit 7 includes two scissor support assemblies 7.1 both connected to the chassis 1 and the support platform 6. Each of the two scissor support assemblies 7.1 includes a first support rod 7.1.1 and a second support rod 7.1.2, and the first support rod 7.1.1 and the second support rod 7.1.2 are hinged. The hinged part of the first support rod 7.1.1 and the second support rod 7.1.2 is connected through a rotating shaft rod 7.2. The top ends of both first support rods 7.1.1 are hinged to a first connecting seat 7.1.3 fixedly connected to the support platform 6.

[0035] Then, rotate the control handle 2.3 to drive the screw rod 2.2 to rotate. Since the screw rod 2.2 is threadedly connected to the fixed plate 2.1, when the screw rod 2.2 rotates, it will slide downward, thereby driving the support bottom plate 2.5 to move downward and contact the ground, and adjusting the support platform 6 to a horizontal state, so as to provide stable support in different terrains and working environments.

[0036] Then, control the first motor 7.4 to start, driving the first lead screw 7.5 to rotate.

Specifically, when the first support rod 7.1.1 and the second support rod 7.1.2 move, the first support rod 7.1.1 rotates around the first connecting seat 7.1.3 and slides on the first slide rail 7.1.5 through the first roller 7.1.4, and the second support rod 7.1.2 rotates around the second connecting seat 7.1.8 and slides on the second slide rail 7.1.7 through the second roller 7.1.6, so that the scissor lifting unit 7 can smoothly lift the support platform, thereby adjusting the height of the support platform 6 to meet the installation or repair needs of different electrical equipment.

[0037] When it is necessary to expand the working area of the support platform 6, start the second motor 13 to drive the second lead screw 14 to rotate, and drive the expansion plate 9 to slide out along the cavity 8 under the guidance of the T-shaped slider 15 and the T-shaped chute 16, forming an expanded working area, providing a larger operating space for the installation or repair of electrical equipment and improving work efficiency.
