Technical Field

[0001] This invention belongs to the technical field of high-altitude, large-span, continuous structure lifting and installation devices, specifically, it relates to a high-altitude, large-span, continuous structure lifting and installation device and its method. Background Technology

[0002] With the development of the economy and society and the continuous progress of construction technology, the number of super high-rise buildings in cities is increasing. Due to the scarcity of land resources, high-rise large-span building structures, aerial connected structures, high-rise large-span and large cantilever structures are becoming more and more common; the difficulty and danger of construction are also increasing significantly.

[0003] Existing construction methods typically involve using a hydraulic lifter in conjunction with a steel strand to lift structural components. However, during use, the steel strand can stretch due to the tension, leading to tilting of the lifted items. This affects the stability of subsequent installation and poses a safety hazard. Additionally, grease can seep out from the steel strand during use, especially in winter. Furthermore, due to the harsh conditions at construction sites, the grease can accumulate dust, resulting in sludge that affects usability and requires regular manual cleaning. These methods have certain shortcomings. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a high-altitude, large-span, continuous structure lifting and installation device that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: a high-altitude, large-span, continuous structure lifting and installation device, including a frame hoisting point, and further comprising:

[0006] Two sets of hydraulic lifters are connected to the lifting points on the frame, and steel strands are connected inside the hydraulic lifters;

[0007] An upper mounting plate is connected to a lifting point on the frame, and multiple sets of connecting rods are fixedly connected to the upper mounting plate;

[0008] The lower mounting plate is fixedly connected to the connecting rod. Both the lower mounting plate and the upper mounting plate are provided with openings for passing through the steel strand rope.

[0009] A sliding block is slidably connected to the connecting rod. The sliding block has an opening, and two sets of telescopic rods are fixedly connected in the opening. A locking half-ring is fixedly connected to the telescopic end of the telescopic rod, and the locking half-ring is matched with the steel strand.

[0010] A touch switch is connected to the upper mounting plate;

[0011] Touch switch 2 is connected to the lower mounting plate, and both touch switch 1 and touch switch 2 are located within the sliding range of the sliding block;

[0012] The lifting device is mounted on the steel strand.

[0013] To facilitate long-term use, rubber pad one and rubber pad two are further connected to the upper mounting plate and the lower mounting plate, respectively.

[0014] To further ensure proper use of the switches, the first and second touch switches are located inside the first and second rubber pads, respectively, and the trigger ends of the first and second touch switches are higher than the first and second rubber pads.

[0015] To facilitate the lifting and transportation of structural workpieces, the lifting device further includes a lifting plate and a clamping plate. The lifting plate is connected to two sets of steel strands, and a rotating screw is threadedly connected to the lifting plate. One end of the rotating screw is fixedly connected to the clamping plate, and the clamping plate is slidably connected inside the lifting plate.

[0016] To facilitate the rotation of the lead screw, a rotating handle is further fixedly connected to the lead screw.

[0017] To facilitate the sliding of the clamping plate, a long rod is slidably connected to the lifting plate, and one end of the long rod is fixedly connected to the clamping plate.

[0018] To facilitate the installation of the hydraulic lifter, a lifter support plate is further connected to the lifting point on the frame, and the hydraulic lifter is connected to the lifting point on the frame through the lifter support plate.

[0019] To facilitate installation stability, the lifting plate is further provided with threaded fixing bolts, which connect the lifting plate to the lifting points on the frame. The upper mounting plate is also provided with threaded mounting bolts, which connect the upper mounting plate to the lifting points on the frame.

[0020] To facilitate installation, multiple sets of frame components are connected to the lifting points on the frame, and the lifter plate is connected to the frame components.

[0021] A method for using a high-altitude, large-span, continuous structure lifting and installation device, characterized in that:

[0022] Step 1: Select a suitable lifting point, install the hydraulic lifter and its components at the lifting point, and conduct experimental operation tests;

[0023] Step 2: Connect the steel strand to the hydraulic lifting device at the upper hoisting point, and connect the steel strand 202 to the lifting device;

[0024] Step 3: Lower the lifting device to the lowering point, install and transport the frame structure to be lifted;

[0025] Step 4: Install the upgraded frame structure.

[0026] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention, through the setting of the locking half ring, can clean the oil and sludge on the surface of the steel strand rope under normal conditions. At the same time, through the setting of touch switch one, touch switch two, and telescopic rod, the tightness of the steel strand rope can be judged by the sequential interval of the sliding block contacting touch switch two, which facilitates the use of the equipment and improves safety.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0038] Example 1:

[0039] Reference Figure 1-8A high-altitude, large-span, integrated structure lifting and installation device includes a frame upper lifting point 1, and further includes: two sets of hydraulic lifters 201 connected to the frame upper lifting point 1, with steel strands 202 connected inside the hydraulic lifters 201; a pump station and a synchronous control system connected to the hydraulic lifters 201; an upper mounting plate 301 connected to the frame upper lifting point 1, with multiple sets of connecting rods 303 fixedly connected to the upper mounting plate 301, the connecting rods 303 being more than one meter in length to facilitate subsequent judgment of the tension of the steel strands 202; and a lower mounting plate 302 fixedly connected to the connecting rods. Both the lower mounting plate 302 and the upper mounting plate 301 have openings for the steel strand 202 to pass through. A sliding block 306 is slidably connected to the connecting rod 303. The sliding block 306 has an opening, within which two sets of telescopic rods 3061 are fixedly connected. A locking half-ring 3062 is fixedly connected to the telescopic end of each telescopic rod 3061, and the locking half-ring 3062 matches the steel strand 202. A first touch switch 3051 is connected to the upper mounting plate 301; a second touch switch 3052 is connected to the lower mounting plate 302. Switch 1 (3051) and touch switch 2 (3052) are both located within the sliding range of sliding block 306. A lifting device is installed on steel cable 202. Rubber pad 1 (3041) and rubber pad 2 (3042) are respectively connected to the upper mounting plate 301 and lower mounting plate 302. Touch switches 1 (3051) and 2 (3052) are located within rubber pads 1 (3041) and 2 (3042), respectively. The trigger ends of touch switches 1 (3051) and 2 (3052) are higher than rubber pads 1 (3041) and 2 (3042). The frame has a lifting point 1. The upper mounting plate 301 is connected to the lifting point 1 on the frame via the lifting plate 203. The lifting plate 203 is threaded with a fixing bolt 2031. The upper mounting plate 301 is threaded with a mounting bolt 3011. The upper mounting plate 301 is connected to the lifting point 1 on the frame via the mounting bolt 3011. Multiple frame assemblies 101 are connected to the lifting point 1 on the frame. The lifting plate 203 is connected to the frame assembly 101.

[0040] The hydraulic lifter 201 in this device has a core-through structure with a steel strand 202 running through the middle and active anchors at both ends. It uses the self-locking property of the reverse movement of the wedge-shaped anchor plates to clamp the steel strand 202 and lift it upward. It can be two TJJ-600 type hydraulic lifters 201 or TJJ-2000 type hydraulic lifters 201.

[0041] The steel strand 202 hole inside each hoist should be aligned with the center of the steel strand 202 hole on the lifting beam. The position should be adjusted according to the hydraulic lock orientation. Each hoist is fixed at the bottom with a pressure plate. The installation method for the steel strand 202 should be selected based on the actual situation. The lower steel strand 202 of the hoist should be inserted directly below the hoist into the corresponding lifting anchor and locked (try to ensure the bottom of the protruding steel strand 202 is level). Any remaining steel strand 202 at the top of each hoist should be led out along the guide frame.

[0042] The installation process for steel strand 202 is as follows: Cut the steel strand 202 to the specified length using a grinding wheel cutter or gas cutter. Use a grinder or gas cutter to smooth and round both ends of the steel strand 202, ensuring no loose strands. Install the guide plate directly below the hoist. Adjust the position of the guide plate holes to align with the anchor holes of the hoist (note the triangular structure). Temporarily fix it. Use a guide pipe to check the top anchor, upper anchor, middle partition plate, lower anchor, safety anchor, and guide plate holes of the hoist from top to bottom, ensuring all six holes are aligned. Mark the guide plate; typically, the innermost hole pointing outwards along the hoist's arrangement direction is hole #1. Each steel strand 202 of the hoist must be threaded in alternating left and right turns. After threading two steel strands 202, clamp them together with clamps to prevent them from slipping out of the air. Generally, thread a small portion of the outer loop first, then the entire inner loop, and then thread the remaining outer loop (alternating left and right turns). After all the steel strands 202 are threaded, lock them with upper and lower anchor cylinders and lock the anchor at each lifting point. Selection of steel strands 202: According to the parameters of the selected hoisting equipment, the TJJ-2000 hoist has a steel strand 202 diameter of 15.2mm and can thread 18 steel strands 202; the TJJ-600 hoist has a steel strand 202 diameter of 15.2mm and can thread 7 steel strands 202.

[0043] Before use, check whether the cable and control line connections between the pump station, the synchronous control system and the hydraulic lifter 201 are correct; check whether the oil pipe connections between the pump station and the main cylinder and anchor cylinder of the hydraulic lifter 201 are correct; power on the system and check the rotation direction of the hydraulic pump spindle. Without starting the pump station, manually operate the corresponding button in the main controller of the synchronous control system to check whether the operation of each solenoid valve and shut-off valve is normal, and whether each shut-off valve corresponds to each lifter number.

[0044] The structural components can then be transported and installed.

[0045] After preparation, the lifting and transportation can begin. The structural workpiece to be transported is installed in the lifting device, and then the pump station is started. The operation of the hydraulic lifter 201 is controlled by the pump station, which moves the steel strand 202 and lifts the lifting device. At this time, the locking half ring 3062 in this device has two working modes. One is to clean the surface of the steel strand 202. In this mode, the telescopic rod 3061 is extended, and the locking half ring 3062 will clamp the steel strand 202. As the steel strand 202 moves, the sliding block 306 will move accordingly until it contacts the upper mounting plate 301 or the lower mounting plate 302. At this time, the sliding block 306 cannot move. Then, the surface of the steel strand 202 can be cleaned by the locking half ring 3062 to prevent dirt on the steel strand 202 from affecting the use and safety of the equipment.

[0046] Secondly, the tension of the steel strand 202 needs to be judged. At this time, the steel strand 202 needs to move upward. At this time, the telescopic rod 3061 does not extend. Under the action of gravity, the sliding block 306 falls onto the lower mounting plate 302 and squeezes the second touch switch 3052. When both sets of second touch switches 3052 are squeezed, the telescopic rod 3061 is activated, the locking half ring 3062 contacts the steel strand 202, and moves upward accordingly. At this time, the sliding block 306 moves upward until it contacts the first touch switch 3051 above. If both sets of first touch switches 3051 are squeezed at the same time, it can be judged that the tension of the two sets of steel strands 202 is about the same. If there is a certain order between the two, then there is a difference in the tension of the two steel strands 202, and the tension needs to be adjusted to avoid affecting subsequent use.

[0047] Example 2:

[0048] Reference Figure 2 A high-altitude, large-span, integrated structure lifting and installation device is basically the same as that in Embodiment 1, but with a further improvement: the lifting device includes a lifting plate 4 and a clamping plate 403. The lifting plate 4 is connected to two sets of steel strands 202. A rotating screw 401 is threadedly connected to the lifting plate 4. One end of the rotating screw 401 is fixedly connected to the clamping plate 403. The clamping plate 403 is slidably connected inside the lifting plate 4. A rotating handle 4011 is fixedly connected to the rotating screw 401. A long rod 402 is slidably connected to the lifting plate 4. One end of the long rod 402 is fixedly connected to the clamping plate 403.

[0049] Specifically, when transporting the structural workpiece, the workpiece is first placed in the lifting plate 4. Then, by rotating the screw 401, the clamping plate 403 is moved to clamp the workpiece and prevent it from falling due to accidental movement. At this time, the pump can be started to lift and move the workpiece. After it is transported to a suitable position, the screw 401 is rotated in the opposite direction to release the clamping of the workpiece and install it.

[0051] Reference Figure 4 A method for using a high-altitude, large-span, continuous structure lifting and installation device, applicable to a high-altitude, large-span, continuous structure lifting and installation device:

[0052] Step 1: Select a suitable lifting point, install the hydraulic lifter 201 and its components at the lifting point, and conduct experimental operation tests.

[0053] Step 2: Connect the steel strand 202 to the hydraulic lifting device 201 at the upper hoisting point, and connect the steel strand 202 to the lifting device;

[0054] Step 3: Lower the lifting device to the lowering point, install and transport the frame structure to be lifted;

[0055] Step 4: Install the upgraded frame structure.

[0056] The present invention, through the setting of the locking half ring 3062, can effectively clean the oil and sludge on the surface of the steel strand 202 under normal conditions. At the same time, through the setting of the first touch switch 3051, the second touch switch 3052 and the telescopic rod 3061, the tightness of the steel strand 202 can be judged by the sequential interval of the sliding block 306 contacting the second touch switch 3052, which facilitates the use of the equipment and improves safety.
