Description

Technical Field

[0001] The present invention relates to the technical field of steel structure installation, and particularly to an auxiliary device for positioning and installing a high-altitude cantilever truss. Background Art

[0002] A truss is a structure formed by connecting rods with hinges at both ends. A truss is generally a planar or spatial structure composed of straight rods with triangular units. The truss rods mainly bear axial tension or pressure, so that the strength of the material can be fully utilized. When the span is large, it can save materials compared with a solid web beam, reduce its own weight and increase stiffness.

[0003] In the Chinese patent with the application number 202311451069.1 and the name of "a positioning device for butt joint of cantilever beams and columns", by manually rotating and screwing the rod to drive the moving box to move downwards, the cooperation of the moving box and the auxiliary support seat can be used to limit the displacement of the outside of the cantilever beam and column. The cooperation of two groups of rotating rollers and auxiliary rollers realizes the function of facilitating the adjustment of the butt joint position of the cantilever beam and column; However, this patent uses a motor to drive a screw to rotate to lift a fixed cantilever beam and column, and the lifting height is relatively low. The existing cantilever truss is fixed at a relatively high height, and this patent cannot assist in the positioning and installation of a truss at a relatively high height. Currently, when installing a high-altitude cantilever steel truss, a crane is mostly used for hoisting. However, during the hoisting process, only a steel wire rope is used for suspension. Affected by wind force and the swing of the crane during the hoisting process, the steel truss is extremely easy to shake. On the one hand, simply controlling the swing speed by the crane is slow and it is easy to collide with other components, causing damage to the finished product and potential safety hazards. On the other hand, it is very difficult to control the alignment and welding of the end of the steel truss with the embedded section steel column. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. A positioning and installation component is provided. The steel wire ropes at the lifting end of the crane are respectively connected with the two support suspensions. The lifting end of the crane drives the truss to rise, and the rolling wheels rise rapidly along the grid frame. Under the limiting action of the grid frame, the truss will not swing when rising, avoiding the collision of the truss with other components, avoiding the damage of the finished product, and ensuring the construction safety; When the truss moves to the installation position, the swing electric push rod drives the swing gear and the swing shaft to rotate. Under the limiting action of the clamping strip, the sliding sleeve is driven to rotate, and the rotary motor drives the assembly seat and the grid frame to rotate, realizing the rotational adjustment of the truss, so that the angle of the clamped truss matches the installation angle, and there is no need to manually pull the steel truss to adjust the installation angle, reducing the manual labor intensity; Subsequently, the fine-tuning electric push rod drives the sliding sleeve to move on the swing shaft, aligning the clamped end of the truss with the embedded steel column. After alignment, the moving motor drives the driving bevel gear to rotate, which drives the driven bevel gear and the moving roller to rotate under the gear drive. The rotation of the moving roller drives the clamped truss to move, making the end of the truss fit with the embedded steel column. Then the worker can connect the truss with the embedded steel column. During the hoisting process, the steel truss can be quickly lifted, and the precise docking and installation of the steel truss are realized by the drive of the swing electric push rod, the fine-tuning electric push rod and the moving motor, further reducing the manual labor intensity. Compared with the existing installation method, the construction efficiency is higher; The truss is placed on the top of the moving rollers at the bottom. The clamping motor drives the bidirectional screw to rotate. Under the limiting and guiding action of the clamping slide rail, the clamping motor drives the roller frames and the moving rollers at the bottom and the top to approach each other, and the truss is fixed under the clamping of the moving rollers at the bottom and the top. The up and down adjustment of the moving rollers at the bottom and the top can clamp trusses of various sizes, with a wide range of applications.

[0016] 2. There is a strengthening and stabilizing component. The pressure sensor senses the weight of the clamped truss and feeds the pressure data back to the controller. The controller controls the stabilizing motor to drive the stabilizing screw to rotate. Under the drive of the stabilizing motor, the counterweight frame moves along the support slide rod. The movement of the counterweight frame changes the moment of the counterweight. Through the feedback of the pressure sensor, the stabilizing motor makes an adaptive adjustment to make the weights on both sides of the lifting C-shaped frame more balanced. When the truss is lifted, the truss can be stably lifted, and the operation stability of the device is good; Under the connection and transportation of the air delivery pipe and the air delivery box, the air delivery pump delivers air into the moving roller. The air flows through the communication holes and enters the airbag. The airbag expands and wraps the truss clamped by the moving roller, increasing the contact area of the clamping, making the clamping of the truss more stable and the clamping and fixing effect better; Place the counterweight block inside the counterweight box. The counterweight block can increase the weight of the support base, making the overall device more stable. Start the support cylinder, and the support cylinder drives the support plate to fit with the ground. The support plate increases the support area of the overall device, further improving the stability.

[0017] In summary, in the positioning and installation component, the saddle can drive the overall device to move, which is more convenient during the installation of the truss. By stacking multiple lattice frames, the truss at a higher height can be positioned and installed. Compared with the prior art, the application range is wider and the movement is more convenient. The strengthening and stabilizing component increases the contact area of the clamping. Compared with the prior art, the clamping of the truss is more stable and the overall stability is higher.

[0022] The working principle and usage process of the present invention: Device assembly. Move the seat 1 to the installation position of the steel truss, connect the counterweight box 317 and the support base 201 with bolts, and place the base counterweight blocks 318 inside the counterweight box 317. The base counterweight blocks 318 can increase the weight of the support base 201, making the overall device more stable. Start the support cylinder 320. The support cylinder 320 drives the support plate 321 to fit with the ground. The support plate 321 increases the support area of the overall device, further improving the stability, and realizing the installation of the device base; Next, connect and assemble multiple lattice frames 204 with bolts according to the height of the steel truss to be hoisted. After the connection and assembly of the lattice frames 204 are completed, use a crane to lift the lattice frames 204, connect one end of the bottom of the lattice frames 204 to the assembly seat 203 with bolts, stably fix the lattice frames 204 on the top of the assembly seat 203, and fix the support U-shaped frame 315 on both sides of the top of the assembly seat 203 with fixing pins 316; Next, place the two lifting U-shaped frames 207 on top of the support U-shaped frame 315, and use bolts to fix the two lifting U-shaped frames 207 on both sides of the bottom grid frame 204. Slip the sliding sleeve 213 over the outside of the swing shaft 209, insert the connecting seat 233 into the inside of the connecting sleeve seat 229 and fix it with a connecting pin 234. Adjust the position of the adjusting sleeve 216 on the adjusting plate 214 according to the length of the steel truss to be clamped, align the corresponding positioning holes 215 and docking holes 217, and fix the adjusting sleeve 216 with a positioning bolt 218 so that the moving rollers 225 at both ends of the two adjusting sleeves 216 can stably clamp the steel truss. Subsequently, place a number of balance counterweight blocks 304 inside the partition cavity 303 of the counterweight frame 302 to complete the assembly of the overall device. The overall device is assembled by connecting in blocks with bolts, which is convenient for installation. When the construction is completed, it is convenient to disassemble the device, easy to transport, and convenient for the repeated use of the device; After the assembly is completed, place the truss on top of the moving rollers 225 at the bottom, start the clamping motor 221, the clamping motor 221 drives the bidirectional screw 223 to rotate. Under the limiting and guiding action of the clamping slide rail 220, the clamping motor 221 drives the two clamping sliders 222 inside the clamping slide rail 220 to approach each other, thereby driving the roller frames 224 and the moving rollers 225 at the bottom and top to approach each other, and fix the truss under the clamping of the moving rollers 225 at the bottom and top. The up and down adjustment of the moving rollers 225 at the bottom and top can clamp trusses of various sizes, with a wide range of applications; Subsequently, start the air delivery pump 313. Under the connection and delivery of the air delivery pipe 314 and the air delivery box 312, the air delivery pump 313 delivers air into the moving roller 225. The air flows through the communication hole 309 into the airbag 310, and the airbag 310 bulges to wrap the truss clamped by the moving roller 225, increasing the contact area of the clamping, making the clamping of the truss more stable and the clamping and fixing effect better; After the clamping and fixing are completed, the pressure sensor 308 senses the weight of the clamped truss and feeds the pressure data back to the controller. The controller controls the smooth motor 306 to operate, and the smooth motor 306 drives the smooth screw 307 to rotate. Driven by the smooth motor 306, the counterweight frame 302 moves along the support slide rod 301. The movement of the counterweight frame 302 changes the moment of the counterweight. Through the feedback of the pressure sensor 308, the smooth motor 306 makes an adaptive adjustment to make the weights on both sides of the lifting U-shaped frame 207 more balanced. When the truss is lifted subsequently, the truss can be lifted stably, making the operation stability of the device better; Subsequently, the steel wire ropes at the lifting end of the crane are respectively connected to the two support suspensions 219. The lifting end of the crane starts to drive the truss to rise. The rolling wheels 235 quickly rise along the lattice frame 204. Under the limiting action of the lattice frame 204, the truss will not swing when rising, avoiding collisions between the truss and other components, preventing damage to the finished product, and ensuring construction safety. When the truss moves to the installation position, the crane stops lifting. The swing electric push rod 211 and the fine-tuning electric push rod 231 operate. The swing electric push rod 211 drives the swing rack 212 to move, thereby driving the swing gear 208 and the swing shaft 209 to rotate. Under the limiting action of the clamping strip 210, the sliding sleeve 213 is driven to rotate. At the same time, the rotating motor 205 drives the assembly seat 203 and the lattice frame 204 to rotate, realizing the rotational adjustment of the truss and making the angle of the clamped truss match the installation angle; Subsequently, the fine-tuning electric push rod 231 drives the sliding sleeve 213 to move on the swing shaft 209, aligning the end of the clamped truss with the embedded steel column. After alignment, the moving motor 227 operates. The moving motor 227 drives the driving bevel gear 228 to rotate. Driven by the gears, the driven bevel gear 226 and the moving roller 225 rotate. The rotation of the moving roller 225 drives the clamped truss to move, making the end of the truss fit the embedded steel column. Then the worker can connect the truss to the embedded steel column. During the hoisting process, the steel truss can be quickly lifted, and the precise docking and installation of the steel truss are realized by the drive of the swing electric push rod 211, the fine-tuning electric push rod 231 and the moving motor 227. The construction efficiency is high. Compared with the existing installation method, there is no need for manual pulling to adjust the installation angle of the steel truss, reducing the labor intensity of workers; After the connection is completed, the clamping motor 221 drives the top and bottom moving rollers 225 to move away from each other. The support cylinder 320 drives the support plate 321 to separate from the ground. The vehicle seat 1 drives the lattice frame 204 to move, enabling the top and bottom moving rollers 225 to get rid of the installed truss. Subsequently, the hoisting end of the crane drives the lifting C-shaped frame 207 to descend along the lattice frame 204. The vehicle seat 1 moves to the next truss installation position, and by repeating the above truss installation steps, the trusses can be installed one by one.
