Description

Technical Field

[0001] This utility model relates to the field of power installation technology, and more specifically, it relates to a power support device for power installation. Background Technology

[0002] In the field of power system construction and maintenance, the installation, replacement, and overhaul of high-voltage equipment are crucial to ensuring the reliable operation of the power grid. However, in actual construction, technicians often face the challenge of safely lifting and precisely positioning large power equipment. Existing power support devices often employ simple support structures and lack effective stabilization mechanisms. During the installation of power equipment, especially when encountering uneven ground or external interference, the unstable support base can easily lead to overturning accidents. Such accidents not only damage expensive equipment but also seriously threaten the personal safety of construction personnel. Especially in time-sensitive scenarios such as substation renovation and emergency fault repair, unstable support devices greatly increase operational risks, reduce construction efficiency, and also increase the psychological burden on operators, hindering the smooth progress of meticulous operations.

[0003] In the field operation environment of power engineering, the construction conditions are complex and ever-changing, and the working space is often strictly limited. Due to the limitations of the structural design, the traditional power support device is difficult to adapt to and be flexible enough to meet the diverse construction needs. When faced with power equipment of different specifications, weights and shapes, the support device is difficult to adjust quickly and effectively. Construction personnel often need to use a variety of auxiliary tools or increase manpower to ensure the safety of the installation process. This not only increases the construction cost and prolongs the construction period, but also fails to fundamentally solve the safety hazards in the equipment lifting process. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention provides a power support device for power installation, so as to solve the technical problems mentioned in the background art.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power support device for power installation, comprising a support frame, a lifting assembly mounted on the support frame, an installation plate fixedly mounted on the top of the lifting assembly, a support mechanism provided on the bottom surface of the support frame, the support mechanism comprising a sleeve and a sliding plate, the sleeve being fixed to the bottom surface of the support frame, the sliding plate sliding on the inner sides of both ends of the sleeve, multiple sets of sliding plates having adjustment holes, multiple sets of sliding rods having screws threadedly connected to their top ends, multiple sets of screws having support blocks fixedly mounted on their bottom ends, a fixing mechanism provided on the sleeve, the fixing mechanism comprising a fixing sleeve and a plug rod, the fixing sleeve being fixed to the top surface of the sleeve, the plug rod being inserted into the fixing sleeve, the plug rod having a pin fixedly mounted on its bottom end, a locking block provided on the inner side of the fixing sleeve, multiple sets of locking blocks being provided, and a locking groove provided on the outer wall of the plug rod, multiple sets of locking grooves being provided and respectively abutting against multiple sets of locking blocks.

[0007] The present invention is further configured such that multiple sets of adjustment holes are distributed on the outer wall of the slide plate, and the plug is inserted into the sleeve and the adjustment hole. This configuration realizes the multi-level adjustment function of the slide plate position, enabling the support device to adapt to different working conditions and equipment sizes. The double plugging method of the plug provides a stable locking effect, effectively preventing the slide plate from moving accidentally during use, and improving the safety and reliability of the entire support system.

[0008] The present invention is further configured such that a positioning block is fixedly provided at the top of the insertion rod, and a positioning hole is provided on the inner side of the fixing sleeve. Both the positioning block and the positioning hole are polygonal. This configuration prevents the insertion rod from rotating in the fixing sleeve through the polygonal structure, ensuring that the insertion rod can only be inserted in the preset direction, thereby enhancing the positioning accuracy. At the same time, the contact area of ​​the polygon is larger than that of the circle, which improves the load-bearing capacity and anti-torsion performance, and extends the service life of the device.

[0009] The present invention is further configured such that each of the multiple sets of positioning blocks is fixedly provided with a handle, and each of the multiple sets of screws is fixedly provided with a knob. This configuration provides the operator with a convenient gripping point, making the insertion and removal of the insertion rod and the adjustment of the screw more effortless and smooth. Especially in working environments where gloves are worn or hands are wet, the humanized design of the handle and knob greatly reduces the difficulty of operation for construction workers and improves work efficiency and operating comfort.

[0010] The present invention is further configured such that each of the multiple sets of locking blocks is fixedly provided with an inclined block on its outer side, and an inclined groove is provided on the inner side of the fixing sleeve. The inclined groove is provided in multiple sets and is slidably connected to the multiple sets of inclined blocks respectively. This configuration forms a guiding mechanism, which enables the locking blocks to slide smoothly along the inclined groove when subjected to force, reducing the resistance of the locking block movement. At the same time, the inclined surface design converts the vertical thrust into the horizontal locking force, enhancing the locking effect and improving the sensitivity and reliability of the entire locking mechanism.

[0011] The present invention is further configured such that a clearance groove is provided at the bottom of each of the multiple sets of card slots, and the top of each of the multiple sets of card blocks is set to an arc shape. This configuration allows the card block to slide smoothly over the bottom of the card slot during insertion. The arc shape design reduces the friction and collision between the card block and the card slot. The clearance groove provides initial positioning space for the card block, making the locking process smoother, effectively reducing component wear and extending the service life of the device.

[0012] The present invention is further configured such that a sliding groove is provided on the outer side of the fixed sleeve, and multiple sets of sliding grooves are provided and slidably connected to the sliding sleeves. A push ring is fixedly provided on the inner side of the sliding sleeves, and the push ring abuts against the bottom surface of multiple sets of locking blocks. A tension spring is provided to connect the sliding sleeves and the outer wall of the fixed sleeves. This configuration realizes a clever mechanism of external operation and internal locking. The operator only needs to push the sliding sleeves to indirectly control the position of the locking blocks. The tension spring ensures that the sliding sleeves can automatically return to their original position, making the entire unlocking system simple and reliable to operate, and greatly improving the practicality and ease of operation of the device.

[0013] The present invention is further provided in that a return spring is connected between the bottom surface of the multiple sets of card blocks and the inner wall of the fixed sleeve. This provision provides a reliable return force to the card blocks, ensuring that the card blocks can automatically return to the initial position after the push ring is removed, thus forming the automatic unlocking function of the locking mechanism. The elastic design of the return spring enables the locking system to maintain good sensitivity after frequent use, thereby improving the reliability and durability of the entire device. Beneficial effects

[0014] Compared with the prior art, the present invention provides a power support device for power installation, which has the following advantages: 1. By designing a combined structure of support frame and lifting components, the safety hazard of side tipping caused by unstable support base in traditional power equipment installation is solved. The device adopts a support mechanism combining sleeve and sliding plate, which allows the support area to be flexibly adjusted according to site conditions. The design of multiple sets of adjustment holes on the sliding plate provides a variety of positioning possibilities under different working conditions. The cooperation structure between the screw and the support block can make precise adjustments for uneven ground conditions, significantly improving the stability and safety of the equipment during lifting, effectively reducing the incidence of construction accidents, and providing reliable technical support for power system construction and maintenance.

[0015] 2. Through the ingenious cooperation of multiple sets of locking blocks and slots, the precise locking of the slide plate position is achieved. The polygonal design of the positioning block and positioning hole prevents rotational misalignment and ensures accurate positioning during installation. The double locking function of the plug greatly enhances the reliability of the entire support system. The sliding connection between the inclined block and the inclined slot makes the locking process smoother. The design of the clearance slot and the arc-shaped locking block reduces friction and wear between components and improves the service life of the device. These designs perfectly solve the problem of insufficient flexibility of traditional devices in complex working environments, enabling construction personnel to quickly respond to changing site conditions.

[0016] 3. This device establishes a convenient unlocking mechanism through the linkage structure of the sliding sleeve and the push ring. Operators only need to push the sliding sleeve to quickly complete the fixing or unlocking operation. The elastic combination of the tension spring and the return spring ensures that the mechanical parts can be reliably reset, avoiding jamming or failure. The user-friendly design of the handle and knob makes the device easy to operate even in confined spaces. The overall structure is compact and reasonable, and the components work together smoothly, greatly improving the efficiency and accuracy of power installation work, reducing the labor intensity of construction personnel, and meeting the high standards of modern power engineering for equipment installation accuracy and construction safety, thus providing a solid engineering foundation for the stable operation of the power system.
