[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

[0026] Example 1:

[0027] Reference Figures 1-3 A lifting device for installing a steel truss structure in a building includes a hydraulic base 100, a support column 200, and a push plate 300.

[0028] The hydraulic base 100 serves as the basic support and power source for the entire lifting system. A support column 200 is installed on the hydraulic base 100 via a flange. A push plate 300 is fixedly installed on the support column 200 to support and push the steel truss to be installed. The push plate 300 has multiple evenly distributed positioning holes 310 on its surface to facilitate quick docking with the truss nodes.

[0029] Specifically, the support column 200 includes a first column 210 and a second column 220 assembled together. A connecting sleeve 230 is installed on the first column 210 and is threadedly connected to the second column 220.

[0030] This utility model provides a jacking device for installing a steel structure truss. A hydraulic base 100 is placed in a designated position and adjusted to adapt to ground conditions, ensuring the stability and reliability of the entire device. Support columns 200 are installed, and the first column 210 and the second column 220 are spliced ​​together via connecting sleeves 230. The pre-assembled steel truss on the ground is hoisted above the push plate 300. The positioning holes 310 on the push plate 300 are used to precisely align with the truss nodes, completing temporary fixation. The hydraulic system is activated to lift the flange 120, thereby pushing the support columns 200 and the push plate 300. The entire truss rises synchronously with the push plate 300 to the design elevation, achieving rapid alignment with the truss nodes. The entire device adopts a standardized and modular design, making disassembly convenient and transportation flexible. It is suitable for various engineering scenarios, significantly improving equipment turnover and utilization efficiency, and is easy to transport and assemble, thus improving installation efficiency.

[0031] Example 2

[0032] The lifting device provided in Example 1 is further optimized, referring to... Figure 2 The first column 210 has an inwardly extending insertion groove 211 at one end near the second column 220, which is stepped or conical in design to facilitate the insertion of the second column 220. The second column 220 has an insertion end 221 that matches the insertion groove 211 to ensure a tight fit between the two.

[0033] To enhance the sealing and stability of the connection, a sealing ring 222 is fixedly installed on the insertion end 221. The sealing ring 222 is made of weather-resistant rubber or silicone material. During the insertion process, the sealing ring 222 is compressed and tightly adheres to the inner wall of the insertion groove 211, forming a good sealing environment. This effectively prevents rainwater, dust and other impurities from entering the column, avoiding internal corrosion and degradation of mechanical properties. At the same time, it plays a buffering role, reducing the impact of vibration on the structure and improving the reliability of the connection.

[0034] With the above structure, the first column 210 is vertically installed on the hydraulic base 100. The insertion end 221 of the second column 220 is aligned with the insertion groove 211 of the first column 210 and slowly inserted to ensure that the sealing ring 222 is fully embedded and fits, thus completing the initial connection. The external thread is reinforced using the connecting sleeve 230 to achieve structural locking. The entire equipment can be quickly disassembled and easily transported to the next construction site for reuse.

[0035] Example 3

[0036] The lifting device provided in Embodiment 1 or 2 is further optimized, referring to Figure 2 The connecting sleeve 230 includes a slip ring 231 rotatably mounted on the first column 210, which can rotate freely around its axis. A sleeve body 232 is slidably mounted on the slip ring 231 for connecting the second column 220.

[0037] The slip ring 231 is provided with a first sliding groove 233 spaced apart, and a first slider 234 is installed on the inner wall of the sleeve 232. A first spring 235 is fixedly connected between the first slider 234 and the inner side wall of the first sliding groove 233, allowing the sleeve 232 to perform lateral displacement compensation within a certain range.

[0038] With the above structure, when the second column 220 is inserted into the sleeve 232, the slider is pulled inward due to the preload of the first spring 235. This pull is transmitted to the second column 220 through the sleeve 232, making it more tightly embedded in the insertion groove 211 of the first column 210. Even if the connection becomes loose due to vibration or load changes during construction, the first spring 235 can automatically compensate for the gap and maintain the connection stability.

[0039] Example 4

[0040] The lifting device provided in the above embodiments is further optimized, referring to... Figure 1 and Figure 3A connecting ring 240 is slidably installed on the sleeve 232 for connecting with adjacent trusses. The connecting ring 240 is composed of multiple sector blocks 241. A second slider 242 is fixedly installed on the side of any sector block 241 near the sleeve 232. A second sliding groove 236 is correspondingly opened on the sleeve 232. A third sliding groove 243 is opened on the other side of the sector block 241. A connecting sleeve 250 is slidably connected in the third sliding groove 243.

[0041] A limiting groove 244 is provided on one side of the contact surface of adjacent sector blocks 241, and a limiting block 245 is installed on the other side. When two sector blocks 241 are connected, the limiting block 245 on one sector block 241 is slidably connected to the limiting groove 244 on the adjacent sector block 241.

[0042] With the above structure, adjacent sector blocks 241 can change their position and height on the sleeve 232 by sliding connection. After reaching the designated position, the device is fixed by the connecting sleeve 250, which improves the flexibility of the device and adapts to different construction needs.

[0043] Example 5

[0044] The lifting device provided in the above embodiments is further optimized, referring to... Figure 1 The hydraulic base 100 includes a hydraulic cylinder 110, which serves as the power source for the lifting device and provides upward thrust. A flange 120 is fixedly installed at the output end of the hydraulic cylinder 110 for connecting other components. A foot plate 130 is fixedly installed at the other end of the hydraulic cylinder 110 to enhance overall stability by ground fixation. Anchor holes 131 are fixedly installed on the foot plate 130 for firmly anchoring the foot plate 130 to the working surface.

[0045] With the above structure set up, the position of the hydraulic base 100 is determined on the selected working surface, and the surface is cleaned and leveled. The hydraulic base 100 is placed in place so that the foot plate 130 is completely in contact with the ground. Expansion bolts are passed through the anchor holes 131 to firmly fix the foot plate 130 to the ground. According to actual needs, a suitable flange 120 is selected and connected to the component to be lifted. The hydraulic system parameters are adjusted to ensure that the lifting action meets the expected requirements. The hydraulic system is started, and the pressure is slowly increased to push the hydraulic cylinder 110 to extend, driving the flange 120 and the component above it to rise. When the predetermined height is reached, the hydraulic pump is stopped, and the current state is maintained to complete the subsequent installation work.

[0046] The usage process of the jacking device for installing steel trusses provided by this utility model is as follows: Place the hydraulic base 100 in the predetermined position, ensuring the foot plate 130 is completely in contact with the ground. Use expansion bolts to pass through the anchor holes 131 to firmly fix the foot plate 130 to the ground, ensuring the stability and reliability of the entire device. Vertically install the first column 210 on the hydraulic base 100. Fix the push plate 300 on the second column 220, ensuring that the positioning holes 310 on its surface face the correct direction for precise connection with the steel truss nodes. Align the insertion end 221 of the second column 220 with the insertion slot 211 of the first column 210 and slowly insert it. The sealing ring 222 is fully embedded and fits, and the external thread is reinforced by the connecting sleeve 230 to achieve structural locking. The adjacent sector blocks 241 can change their position and height on the sleeve 232 arbitrarily through mutual sliding connection. After reaching the designated position, the connecting sleeve 250 is used to fix it, which improves the flexibility of the device and adapts to different construction needs. The hydraulic system is started, and the output end of the hydraulic cylinder 110 drives the flange 120 to rise, which in turn pushes the support column 200 and the push plate 300 to move upward as a whole. The entire truss is raised to the design elevation synchronously with the push plate 300. After the installation task is completed, the pressure of the hydraulic cylinder 110 is gradually reduced, so that the lifting component slowly descends to the final position.

[0047] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
