Description

Technical Field

[0001] This invention relates to the field of building auxiliary equipment technology, specifically to a high-altitude roller sliding device for large-span steel trusses. Background Technology

[0002] With the development of prefabricated steel structure building engineering in my country, the construction of various high-rise and super high-rise steel structure buildings and large steel structure stadiums is increasing. During the construction of these prefabricated steel structure buildings, due to site limitations, it is often impossible to use large hoisting machinery to directly hoist the steel structure truss to the installation position of the beam. Usually, a large-span steel structure truss high-altitude roller sliding device is used to assist in the installation of the steel structure truss.

[0003] Existing high-altitude roller sliding devices for large-span steel trusses mainly employ two methods: electric hoist pulling and hydraulic cylinder gradual pushing. When using an electric hoist and cable to pull the steel structure along the truss, the long cable length results in a significant amount of wasted effort as the electric hoist pulls the truss. As for the hydraulic cylinder gradual pushing method, maintaining pressure requires long pipelines for hydraulic fluid transmission, making it very inconvenient to use. Therefore, there is a need to develop a high-altitude roller sliding device for large-span steel trusses. Summary of the Invention

[0023] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0024] Please see Figures 1-8 The diagram shows a structural schematic of an embodiment of a high-altitude roller sliding device for a large-span steel truss according to the present invention. Please refer to [link / reference]. Figures 1-8 This paper provides a detailed introduction to a high-altitude roller sliding device for a large-span steel truss structure.

[0025] Example 1: A high-altitude roller sliding device for a large-span steel truss includes a support mechanism 100, a clamping mechanism 200, a moving mechanism 300, and an auxiliary mechanism 400. The support mechanism 100 includes a crossbeam 101 with an "I"-shaped cross section and symmetrically formed beam grooves 102 on both sides along its length. Vertical support columns 103 are fixedly installed at equal intervals along the bottom of the crossbeam 101. The support columns 103 are made of concrete. The concrete support columns 103 at equal intervals at the bottom of the crossbeam 101 help to enhance the support strength of the crossbeam 101. The concrete material can provide good load-bearing capacity, and the equal interval arrangement can distribute the load and further improve the stability of the entire support mechanism 100. The clamping mechanism 200 is installed above the crossbeam 101 and is used to fix and disassemble the truss 500. It includes a mounting plate 201 for placing the truss 500. The moving mechanism 300 is located below the mounting plate 201 and above the crossbeam 101. It is used to drive the mounting plate 201 and the truss 500 to move on the crossbeam 101. It includes two sets of mounting frames 301 fixed to the bottom of the mounting plate 201. Each set of mounting frames 301 has a transverse roller 302 rotatably mounted on its side wall via bearings. Rollers 303 are fixedly mounted on the shafts of the two rollers 302. The rollers 303 roll along the top of the crossbeam 101, and their outer surfaces are provided with anti-slip textures. The anti-slip textures on the outer surface of the rollers 303 can increase the friction with the top of the crossbeam 101, which helps to reduce slippage during the rolling process. The auxiliary mechanism 400 is disposed below the mounting plate 201 and on both sides of the moving mechanism 300, and is used to install crossbeams 101 of different thicknesses and beam grooves 102 of different depths, ensuring that the mounting plate 201 and the truss 500 move along the length of the crossbeams 101. In this embodiment, the high-altitude sliding of the large-span steel truss 500 can be achieved through the coordinated operation of the support mechanism 100, clamping mechanism 200, moving mechanism 300, and auxiliary mechanism 400. The I-shaped crossbeam 101 and beam groove 102 provide the supporting foundation for the auxiliary mechanism 400. The clamping mechanism 200 facilitates the fixing and disassembly of the truss 500.

[0028] In Example 4, based on Example 1, the auxiliary mechanism 400 includes a spline rod 401 fixed to the left end of each roller 302. The spline rod 401 and the roller 302 are coaxially arranged. Spline sleeves 402 are slidably arranged on the two spline rods 401 respectively. An "L"-shaped movable frame 403 is rotatably arranged on the outer side of the two spline sleeves 402 through bearings. A transverse first connecting plate 404 is fixed between the two movable frames 403. The sliding fit between the spline rod 401 and the spline sleeve 402 allows the movable frame 403 to move axially along the roller 302 within its range of motion, which is convenient for adapting to crossbeams 101 of different thicknesses. This provides a structural basis for the adjustment of the auxiliary mechanism 400 and helps to improve the adaptability of the device. Furthermore, the auxiliary mechanism 400 also includes two fixed frames 405 fixedly disposed on the bottom of the mounting plate 201 away from the movable frame 403. The two fixed frames 405 are in a mirror "L" shape. The rods of the two rollers 302 rotate through the side walls of the two fixed frames 405 respectively via bearings on the right side. A second connecting plate 406 parallel to the first connecting plate 404 is fixedly disposed between the two fixed frames 405. The side wall of the first connecting plate 404 is threaded through and provided with a second self-locking threaded rod 407 perpendicular to it. One end of the second self-locking threaded rod 407 is rotatably connected to the side wall of the second connecting plate 406 through a bearing. The other end of the second self-locking threaded rod 407 is provided with a second turntable 408. The outer surface of the second turntable 408 is provided with anti-slip texture. The second self-locking threaded rod 407 is located above the crossbeam 101 and is spaced apart from it; the second self-locking threaded rod 407 is located between the two rollers 303 and is spaced apart from them. Furthermore, the auxiliary mechanism 400 also includes auxiliary moving components 409 disposed on one side of the bottom of the two movable frames 403 and one side of the bottom of the two fixed frames 405. The two auxiliary moving components 409 are symmetrically arranged about the crossbeam 101, and the two auxiliary moving components 409 slide on the upper and lower surfaces of the inner side of the beam groove 102 on the left and right sides respectively. In this embodiment, the distance between the movable frame 403 and the fixed frame 405 can be adjusted by the second self-locking threaded rod 407, which makes it easy to fix the device on the crossbeam 101 of different thicknesses within a certain range; the anti-slip texture of the second turntable 408 makes it easy for the operator to rotate and adjust; the position setting of the second self-locking threaded rod 407 can avoid interference with the roller 303 and the crossbeam 101, ensuring the normal operation of each component.

[0029] It should be noted that, in Embodiment 1, the auxiliary mechanism 400 is indicated for installation on crossbeams 101 of different thicknesses and beam grooves 102 of different depths. This means that the auxiliary mechanism 400 is used to install on crossbeams 101 of different thicknesses and beam grooves 102 of different depths within a certain range. This range does not exceed the range of sliding fit between the spline rod 401 and the spline sleeve 402, nor does it exceed the range of the distance between the movable frame 403 and the fixed frame 405 that can be adjusted by the second self-locking threaded rod 407.

[0030] In Example 5, based on Example 4, the auxiliary moving component 409 includes a strip plate 410 that fixes one side of the bottom of two movable frames 403 and one side of the bottom of two fixed frames 405. Each strip plate 410 is symmetrically hinged with movable rods 411 on its upper and lower sides. The other end of each movable rod 411 is rotatably equipped with an auxiliary wheel 412. The auxiliary wheels 412 in the upper and lower positions roll with the upper and lower surfaces of the inner side of the beam groove 102, respectively. Each movable rod 411 is hinged with a linkage rod 413 on the side of its body facing the strip plate 410. Furthermore, the upper and lower walls of the strip plate 410 are provided with sliding openings 414. The opening direction of the sliding openings 414 is set along the length direction of the strip plate 410 and the beam groove 102. The inner side wall of the sliding opening 414 is rotatably provided with a second double-ended self-locking screw 415 parallel to it through a bearing. The threads on both sides of the second double-ended self-locking screw 415 have opposite directions and are respectively screwed with sliders 416. The left and right side walls of the two sliders 416 are respectively in contact with the left and right inner side walls of the sliding opening 414 and slide against each other. The other end of the linkage rod 413 on the same side at the front and rear and the top and bottom are respectively hinged to the upper and lower surfaces of the sliders 416 at the corresponding positions at the front and rear. One end of the second double-ended self-locking screw 415 is located on the outside of the strip plate 410 and is fixedly provided with a second knob 417. The outer surface of the second knob 417 is provided with anti-slip texture. In this embodiment, by adjusting the position of the slider 416 through the second double-headed self-locking screw 415, the vertical distance between the auxiliary wheel 412 can be adjusted by driving the linkage rod 413 and the movable rod 411, which facilitates installation on beam grooves 102 of different depths within a certain range; the rolling of the auxiliary wheel 412 can reduce friction with the beam groove 102, making it easier to move the device; the anti-slip texture of the second knob 417 facilitates operation, and the self-locking function of the second double-headed self-locking screw 415 helps to maintain the adjusted state, improving ease of use.

[0031] The following is a detailed usage process of this invention: Preliminary Inspection and Preparation: Confirm that the crossbeam 101 is free from deformation, the edges of the beam groove 102 are flat, and the bottom support column 103 is firmly connected to the foundation to ensure reliable overall support; confirm that the battery power is sufficient by checking the indicator lights of the battery box 308, and if insufficient, replenish the power through the charging port; check the connection status of the reduction servo motor 307, roller 302, roller 303, sprocket 304, and chain 305 to ensure that the transmission components are flexible and free from jamming, and that the tensioning mechanism maintains appropriate tension on the chain 305; confirm that the spline rod 401 and spline sleeve 402 slide smoothly, that the movable frame 403 and fixed frame 405 are not loose, and that the auxiliary wheel 412 of the auxiliary moving component 409 rotates flexibly; Installation equipment: After raising the mounting plate 201 with the help of the lifting machinery, place the roller 303 at the bottom of the plate on the crossbeam 101. At this time, the two auxiliary moving components 409 are located on the left and right sides of the crossbeam 101 respectively. Then, by rotating the second turntable 408, the second self-locking threaded rod 407 is driven to rotate. The first connecting plate 404 pushes the movable frame 403 to slide along the spline rod 401 and the spline sleeve 402. Adjust the distance between the movable frame 403 and the fixed frame 405 until the two auxiliary moving components 409 move into the two beam grooves 102 respectively and maintain their positions by using the thread self-locking. Then turn the second knob 417 to drive the second double-headed self-locking screw 415 to rotate. The sliders 416 on both sides move in the opposite direction along the sliding port 414. Through the linkage rod 413, the movable rod 411 is pushed to rotate, so that the distance between the upper and lower auxiliary wheels 412 is adjusted to match the depth of the beam groove 102, ensuring that the auxiliary wheels 412 are in contact with the upper and lower inner surfaces of the beam groove 102 respectively. Install the truss: Place the truss 500 to be slid on the mounting plate 201 of the clamping mechanism 200. Turn the first knob 205 to drive the first double-headed self-locking screw 204 to rotate. Because the threads on both sides of the screw are opposite, the side clamping plates 203 on both sides move towards each other along the sliding groove 202. The guide rod 206 ensures smooth movement until the anti-slip pads of the side clamping plates 203 are in contact with both sides of the truss 500. Use the screw's self-locking function to maintain the clamping state. Then, turn the first turntable 210 to drive the first self-locking threaded rod 208 to move downward, so that the anti-slip pads of the pressing clamping plate 209 contact the top of the truss 500 and apply appropriate pressure to further fix the truss from the vertical direction and prevent it from shaking during the sliding process. Start-stop sliding operation: Start the geared servo motor 307. The motor output shaft drives one of the rollers 302 to rotate through the coupling. The other roller 302 rotates synchronously with the chain 305 through the sprocket 304, causing the roller 303 to roll along the top of the crossbeam 101, driving the mounting plate 201 and the truss 500 fixed on it to move along the length of the crossbeam 101. At this time, the auxiliary wheel 412 rolls synchronously in the beam groove 102, deflecting from the lateral limiting device. When the truss 500 moves to the target position, the geared servo motor 307 is turned off, the sliding stops, and one sliding operation is completed.
