Description

Technical Field

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

[0002] A truss is a structure made up of rods connected to each other at both ends with hinges. A truss is a planar or spatial structure composed of straight rods, generally with triangular units. The truss rods mainly bear axial tension or compression, thereby making full use of the strength of the material. When the span is large, it can save material compared to a solid beam, reduce its own weight and increase stiffness.

[0003] In the Chinese patent application number 202311451069.1, entitled “A Cantilever Beam-Column Docking Positioning Device,” a movable box is driven downward by manually rotating a screw rod. The movable box cooperates with an auxiliary support seat to limit the displacement of the outer side of the cantilever beam column. Two sets of rotating rollers cooperate with auxiliary rollers to facilitate adjustment of the cantilever beam-column docking position.

[0004] However, this patent uses a motor to drive the screw to rotate to lift the fixed cantilever beam column, and the lifting height is relatively low. The existing cantilever trusses are fixed at a high height. This patent cannot assist in the positioning and installation of trusses at higher heights. The existing high-altitude cantilever steel trusses are mostly hoisted by cranes during installation, but during the hoisting process, they are only suspended by steel wire ropes. During the hoisting process, the steel trusses are easily shaken by wind and crane swing. On the one hand, simply controlling the swing speed by crane is slow and easy to collide with other components, causing damage to the finished product and safety hazards. On the other hand, it is difficult to control the alignment and welding of the steel truss ends with the embedded steel columns. Summary of the Invention

[0014] According to the above technical solution, a number of rolling wheels are installed on both sides of the interior of the lifting frame, and the rolling wheels are attached to one side of the adjacent lattice frame.

[0015] According to the above technical solution, strengthening and stabilizing components are provided on both sides of the lattice frame, and the strengthening and stabilizing components include supporting slide bars;

[0016] Another side of the lifting profile frame is equipped with supporting slide bars on both sides, and a counterweight frame is slidably installed between the two supporting slide bars. A plurality of partition chambers are opened inside the counterweight frame, and a plurality of balancing counterweight blocks are placed inside the partition chambers. A connecting ear is connected to one side of the counterweight frame, and a stabilizing screw is connected to the inside of the connecting ear through a threaded hole. A stabilizing motor is installed on one side of the lifting profile frame near one end of the stabilizing screw, and the output end of the stabilizing motor is connected to one end of the stabilizing screw;

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. A positioning installation component is provided to connect the steel wire rope of the crane hoisting end to the two supporting suspensions respectively. The crane hoisting end drives the truss to rise, and the rolling wheel rises rapidly along the lattice frame. Under the limiting effect of the lattice frame, the truss will not swing when rising, avoiding collision between the truss and other components, avoiding damage to the finished product, and ensuring construction safety;

[0023] 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 bar, the sliding sleeve is driven to rotate. The rotating motor drives the assembly seat and the lattice frame to rotate, realizing the rotation adjustment of the truss, so that the clamped truss angle matches the installation angle. There is no need to manually pull the steel truss to adjust the installation angle, which reduces the labor intensity.

[0024] Subsequently, the fine-tuning electric push rod drives the sliding sleeve to move on the swing shaft, so that the clamped truss end is aligned with the embedded steel column. After alignment, the mobile motor drives the driving bevel gear to rotate, and the driven bevel gear and the mobile roller are driven to rotate under the drive of the gear. The rotation of the mobile roller drives the clamped truss to move, so that the truss end is fitted with the embedded steel column. The worker then connects the truss to the embedded steel column. During the lifting process, the steel truss can be lifted quickly, and the precise docking and installation of the steel truss can be achieved by coordinating the swing electric push rod, the fine-tuning electric push rod and the mobile motor, which further reduces the labor intensity. Compared with the existing installation method, the construction efficiency is higher.

[0025] The truss is placed on top of the moving roller at the bottom, and the clamping motor drives the bidirectional screw to rotate. Under the limiting guidance of the clamping slide rail, the clamping motor drives the bottom and top roller frames and the moving rollers to approach each other, and the truss is fixed under the clamping of the bottom and top moving rollers. The bottom and top moving rollers can be adjusted up and down to clamp trusses of various sizes, and it has a wide range of applications.

[0026] 2. It is equipped with a reinforced stabilizing component. The pressure sensor senses the weight of the clamped truss and feeds back the pressure data to the controller. The controller controls the stabilizing motor to drive the stabilizing screw to rotate. Driven by the stabilizing motor, the counterweight frame moves along the supporting slide rod. The movement of the counterweight frame changes the torque of the counterweight. Through the feedback of the pressure sensor, the stabilizing motor performs adaptive adjustment to make the weight on both sides of the lifting frame more balanced. When the truss is lifted, the truss can be lifted stably and the device has good operating stability.

[0027] With the air pipe and the air box connected, the air pump delivers air to the inside of the moving roller. The air flows through the connecting hole 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 truss clamping more stable and achieving a better clamping and fixing effect.

[0028] Placing the counterweight block inside the counterweight box can increase the weight of the support base, making the overall device more stable. Starting the support cylinder, the support cylinder drives the support plate to fit into the ground. The support plate increases the support area of the overall device and further improves stability.

[0029] To sum up, the seat in the positioning and installation assembly can drive the entire device to move, which makes it more convenient to move when installing the truss. By stacking multiple lattice frames, trusses of higher heights can be positioned and installed. Compared with the existing technology, the scope of application is wider and the movement is more convenient. The strengthened stabilization assembly increases the contact area of the clamping, which makes the clamping of the truss more stable and the overall stability higher than the existing technology.

[0056] The working principle and usage process of the present invention are as follows: the device is assembled, the seat 1 is moved to the steel truss installation position, the counterweight box 317 is connected to the support base 201 with bolts, and the base counterweight block 318 is placed inside the counterweight box 317. The base counterweight block 318 can increase the weight of the support base 201, making the overall device more stable.

The support plate 321 increases the support area of the entire device, further improves the stability, and realizes the installation of the device base;

[0057] Next, multiple lattice frames 204 are connected and assembled with bolts according to the height of the steel trusses to be hoisted. After the lattice frames 204 are connected and assembled, they are lifted by a crane, and one end of the bottom of the lattice frame 204 is connected to the assembly base 203 with bolts. The lattice frame 204 is stably fixed on the top of the assembly base 203, and the support profiles 315 are fixed on both sides of the top of the assembly base 203 with fixing pins 316.

[0058] Then, the two lifting profiles 207 are placed on the top of the supporting profile 315, and the two lifting profiles 207 are fixed to the two sides of the bottom lattice frame 204 by bolts, the sliding sleeve 213 is sleeved on the outside of the swing shaft 209, the connecting seat 233 is embedded in the connecting sleeve seat 229 and fixed with the connecting pin 234, and the position of the adjusting sleeve 216 on the adjusting plate 214 is adjusted according to the length of the steel truss to be clamped, and the corresponding positioning holes 215 and the docking holes 217 are aligned, and the adjusting sleeve 216 is fixed with the positioning bolts 218 so that the moving rollers 225 at both ends of the two adjusting sleeves 216 can stably clamp the steel truss. Subsequently, several balancing weights 304 are placed inside the partition chamber 303 in the counterweight frame 302 to complete the assembly of the entire device. The entire device is assembled in blocks using bolts, which is convenient to install. After the construction is completed, the device is easy to disassemble, easy to transport, and easy to reuse.

[0059] After the assembly is completed, the truss is placed on top of the bottom movable roller 225, and the clamping motor 221 is started. The clamping motor 221 drives the bidirectional screw 223 to rotate. Under the limiting guidance 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 bottom and top roller frames 224 and the movable roller 225 to approach each other. The truss is fixed under the clamping of the bottom and top movable rollers 225. The bottom and top movable rollers 225 can be adjusted up and down to clamp trusses of various sizes, and have a wide range of applications.

[0060] Subsequently, the air pump 313 is started. With the air pipe 314 and the air box 312 connected, the air pump 313 delivers air to the interior of the movable roller 225. The air flows through the connecting hole 309 and enters the interior of the airbag 310. The airbag 310 expands and wraps around the truss clamped by the movable roller 225, increasing the contact area of the clamping, making the truss clamping more stable and achieving a better clamping and fixing effect.

[0061] After the clamping is completed, the pressure sensor 308 senses the weight of the clamped truss and feeds back the pressure data to the controller. The controller controls the operation of the stabilizing motor 306, and the stabilizing motor 306 drives the stabilizing screw 307 to rotate. Under the drive of the stabilizing motor 306, the counterweight frame 302 moves along the supporting slide bar 301. The movement of the counterweight frame 302 changes the torque of the counterweight. Through the feedback of the pressure sensor 308, the stabilizing motor 306 performs adaptive adjustment to make the weight on both sides of the lifting frame 207 more balanced. When the truss is lifted later, the truss can be lifted stably, making the operation stability of the device better.

[0062] Subsequently, the steel wire ropes at the lifting end of the crane are connected to the two supporting suspensions 219 respectively, and the lifting end of the crane is started to drive the truss to rise, and the rolling wheel 235 rises rapidly along the lattice frame 204. Under the limiting action of the lattice frame 204, the truss will not swing when rising, thereby avoiding collision between the truss and other components, avoiding damage to the finished product, and ensuring construction safety. When the truss moves to the installation position, the crane stops lifting, and the swing electric push rod 211 and the fine-tuning electric push rod 231 are operated. The swing electric push rod 211 drives the swing rack 212 to move, and then drives 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, thereby realizing the rotation adjustment of the truss, so that the clamped truss angle matches the installation angle.

[0063] Then, the fine-tuning electric push rod 231 drives the sliding sleeve 213 to move on the swing shaft 209, so that the clamped truss end is aligned with the embedded steel column. After alignment, the moving motor 227 is operated, and the moving motor 227 drives the driving bevel gear 228 to rotate. Under the drive of the gear, the driven bevel gear 226 and the moving roller 225 are driven to rotate. The rotation of the moving roller 225 drives the clamped truss to move, so that the truss end is fitted with the embedded steel column. The worker then connects 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 can be achieved by cooperating with 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 to manually pull the steel truss to adjust the installation angle, which reduces the labor intensity.

[0064] After the connection is completed, the clamping motor 221 drives the top and bottom moving rollers 225 away from each other, the support cylinder 320 drives the support plate 321 to separate from the ground, and the seat 1 drives the lattice frame 204 to move, so that the top and bottom moving rollers 225 are free from the installed trusses. Then the crane hoisting end drives the lifting frame 207 to descend along the lattice frame 204, and the seat 1 moves to the next truss installation position. Repeat the above truss installation steps to install the trusses one by one.

[0065] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
