Description

Technical Field

[0001] This utility model relates to the field of power equipment construction tools, and in particular to a GIS equipment landing slow descent device. Background Technology

[0002] In the construction process of the power industry, many substation construction projects require the relocation of large and heavy equipment such as GIS indoors. During this process, it is not possible to use the lifting and installation equipment commonly used for outdoor installation. Instead, it is necessary to rely on tools such as transport tanks to move the large and heavy equipment indoors and install it at the designated location.

[0003] However, since large and heavy equipment such as GIS cannot be directly lowered to the designated location after being transported into the building by tank vehicles, it is necessary to use claw jacks to lower its height to a height that can be used by pry bars. Then, after removing the claw jacks, the pry bars are used to lower the GIS equipment to the ground. The operation process is cumbersome. In addition, during the equipment replacement process, manpower is required to keep the GIS equipment off the ground. Furthermore, after the equipment is lowered, the pry bars still need to be pulled out from under the equipment base, making it impossible to achieve zero height difference positioning. Utility Model Content

[0004] The purpose of this utility model is to solve the drawbacks of the cumbersome use of traditional tools and equipment in the installation of existing GIS equipment, which makes it impossible to achieve zero height difference landing. Through scientific and reasonable structural design, combined with the structural characteristics of GIS equipment, the operation method is simplified, so that the equipment relocation and landing process is safe, fast and accurate, and a GIS equipment landing slow descent device is provided.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A GIS equipment landing slow descent device includes a GIS equipment, a GIS bottom frame, and a GIS-specific moving tool. The device is characterized by: several landing cantilever beams positioned above the GIS bottom frame; cantilever beam lifting claws located on the lower left and right sides of each landing cantilever beam; the cantilever beam lifting claws being connected to the landing cantilever beams via fasteners; and jacks located at the bottom of both ends of each landing cantilever beam.

[0007] Furthermore, the ground-mounted cantilever beam is U-shaped, and several elongated holes are equally spaced at both ends of the base plate.

[0008] Furthermore, the cantilever lifting claw is made of U-shaped steel, and the fastener consists of two sets of bolts and nuts. The bolts are fixedly connected to the upper end of the cantilever lifting claw, and the nuts pass through the elongated hole and are connected to the nut. The fastener can be adjusted according to the size of the bottom frame of the GIS.

[0009] Furthermore, the bottom frame of the GIS is composed of several channel steels, and the groove direction of the cantilever beam lifting claw is opposite to the groove direction of the channel steel of the bottom frame of the GIS, forming an inward buckle.

[0010] Beneficial effects: This utility model has the following beneficial effects:

[0011] 1. Abandoning the traditional complex method of step-by-step operation using claw jacks and pry bars, the GIS equipment can be directly and slowly lowered through the cooperation of the ground cantilever beam, cantilever lifting claw and jack, without the need to change tools multiple times, greatly reducing operation steps and improving installation efficiency;

[0012] 2. Abandoning the traditional method of pulling out the pry bar after it is placed on the ground, the equipment height is gradually lowered using jacks. With the help of the cantilever beam lifting claw and the inner buckling structure of the bottom frame of the GIS, the descent of the equipment can be precisely controlled, so as to achieve the smooth placement of the GIS equipment with zero height difference and ensure installation accuracy.

[0013] 3. It avoids the risk of having to manually keep the equipment off the ground when replacing traditional tools. All components of the device are securely connected by fasteners. The design of several elongated holes on the ground cantilever beam can flexibly adapt to the bottom frame of GIS of different sizes, effectively preventing the equipment from shaking or tilting during the slow descent process, and ensuring construction safety.

[0014] 4. The combination of the cantilever beam lifting claw and fasteners can be adjusted according to the size and slot direction of the bottom frame of the GIS, adapting to various specifications of GIS equipment. The elongated hole design of the ground cantilever beam allows the device to be quickly installed and adjusted in different engineering scenarios, with strong versatility and reduced construction costs.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Combination Figures 1 to 4 The illustrated GIS equipment landing and slow-descent device includes a GIS device 5, a GIS bottom frame 6, and a GIS-specific moving tool 7. Its key feature is that several landing cantilever beams 1 are installed above the GIS bottom frame 6, and cantilever lifting claws 2 are installed on the lower left and right sides of each landing cantilever beam 1. The cantilever lifting claws 2 are connected to the landing cantilever beam 1 by fasteners 3. Jacks 4 are installed at the bottom of both ends of each landing cantilever beam 1. Compared to the cumbersome process of traditional step-by-step operation using claw jacks and pry bars, this device uses the landing cantilever beam 1 spanning the GIS bottom frame 6, with the cantilever lifting claws 2 closely cooperating with the GIS bottom frame 6, and the jacks 4 directly acting on the landing cantilever beam 1. This eliminates the need for multiple tool changes, allowing for one-stop slow-descent of the equipment and greatly improving construction efficiency.

[0022] The ground-mounted cantilever beam 1 is U-shaped, with several elongated holes 8 evenly spaced at both ends of the base plate. This design provides flexible space for adjusting the fasteners 3. When facing GIS bottom frames 6 of different specifications, construction workers can quickly adapt to the equipment size by moving the position of the fasteners 3 in the elongated holes 8, which enhances the versatility of the device, avoids frequent tool changes due to differences in equipment specifications, and reduces construction costs.

[0023] The lifting claw 2 is made of U-shaped steel. The fastener 3 consists of two sets of bolts and nuts. The bolts are fixedly connected to the upper end of the lifting claw 2, and the nuts are connected to the long oval holes 8. The spacing can be adjusted according to the size of the bottom frame 6 of the GIS to ensure that the device can be adapted to various GIS equipment 5.

[0024] The GIS bottom frame 6 is composed of several channel steels. The slots of the cantilever lifting claw 2 are opposite to the slots of the channel steels in the GIS bottom frame 6, forming an inward snap. This inward snap design is the key to achieving zero height difference positioning. During the slow descent, the inward snap structure between the cantilever lifting claw 2 and the GIS bottom frame 6 allows the GIS equipment 5 to descend smoothly along the vertical direction, avoiding height differences caused by tool removal. By controlling the jack 4 to slowly lower the height of the landing cantilever beam 1, the construction personnel can ensure that the GIS equipment 5 is precisely fitted to the installation position without the need for subsequent additional adjustments, thus ensuring high precision in equipment installation and reducing the risk of equipment damage caused by height differences.
