Abstract
Description
Technical Field
[0001] This invention relates to the field of building component transportation technology, and in particular to a pre-assembled sliding installation device for steel structure roofs. Background Technology
[0002] In the construction of large-span buildings such as industrial plants, stadiums, and convention centers, steel structure roofs are often difficult to lift directly using large cranes due to their large weight, high installation height, and the limitations of existing buildings or equipment on the construction site. In these cases, pre-assembled sliding installation technology has become a major solution to these problems. This technology involves pre-assembling roof components on the ground or at low altitude, and then using a sliding device to push the pre-assembled units to the designed position along I-beam tracks. This significantly reduces high-altitude work, lowers lifting risks, and saves construction space, and has become one of the mainstream processes for installing large-span steel structures.
[0003] In existing technologies, sliding devices have been gradually optimized from the simple structure of traditional sliders and pushers. For example, some solutions improve adaptability through graded track design. However, in practical applications in various scenarios, existing sliding devices still have problems with structural design and construction requirements. Specific defects are particularly prominent under complex working conditions. On the one hand, the drive system, braking components, and positioning components of existing devices lack a mandatory coordination mechanism. The processes of drive start-up and brake release, and adjustment component movement and positioning lock-up mostly require manual step-by-step operation. This process is prone to errors such as starting the drive before releasing the brake when sliding at high altitudes, which can easily lead to component wear and roof collisions. The positioning components also require manual tightening of bolts for fixation. On the other hand, existing devices have poor adaptability to I-beam rails of various specifications. Due to the lack of a flexible and adjustable coordination structure, when facing I-beam rails with different flange widths and sidewall thicknesses in different construction projects, it is necessary to manually disassemble and replace special clamping parts or manually adjust bolts. Each adaptation is time-consuming, and because the adjustment accuracy depends on manual experience, it is easy to cause the clamping parts to not fit firmly with the rail. Summary of the Invention
[0004] In view of the problems of existing technology, such as the ease of misoperation due to independent control of drive and brake, poor adaptability to various specifications of I-beams, and the need for manual locking for positioning, a pre-assembled sliding installation device for steel structure roofs is proposed.
[0005] Its purpose is to achieve automated adaptation of multiple specifications of I-beams by adjusting components, forced linkage between drive components and brakes, and automatic clamping and locking of positioning components, thereby solving the problems of difficult adaptation, high safety risks and low positioning efficiency of traditional devices, and thus improving equipment reuse rate, ensuring safety and installation accuracy of high-altitude sliding, shortening construction and commissioning time, and reducing labor and equipment costs.

The components include: a connecting rod disposed on the inner wall of the movable component; the driving component includes a DC motor disposed on the inner wall of the sliding frame, a linkage rod disposed on the output end of the DC motor, movable slots symmetrically opened on the outer wall of the linkage rod, an extension component slidably disposed on the outer wall of the linkage rod, a rotating component rotatably disposed on the outer wall of the extension component, a contact wheel rotatably disposed on the outer wall of the middle part of the linkage rod, a telescopic rod disposed on the side wall of the contact wheel, and a friction disc disposed at the other end of the telescopic rod; the positioning component is used to move in coordination with the movement of the adjusting component and to clamp and position the component according to the thickness of the side wall of the I-beam, and the driving component moves under clamping and positioning.
[0007] Furthermore, the movable component includes a movable frame slidably disposed on the inner wall of the sliding frame, an adjustment frame symmetrically disposed on the outer wall of the movable frame, a limiting groove formed on the inner wall of the movable frame, the inner wall of the movable frame being rotatably connected to the outer wall of the limiting wheel through the limiting groove, the inner wall of the movable frame being fixedly connected to the outer wall of the connecting rod, and the outer wall of the movable frame being fixedly connected to the outer wall of the internal threaded sleeve.
[0008] Furthermore, the extension assembly includes a connecting sleeve slidably disposed on the outer wall of the linkage rod, a sliding protrusion disposed on the inner side wall of the connecting sleeve, a rotating rod rotatably disposed on the outer wall of the connecting sleeve, a friction block rotatably disposed on the outer wall of the rotating rod, a groove formed on the outer wall of the friction block, and a rotating sleeve rotatably disposed on the inner wall of the connecting sleeve. The outer wall of the connecting sleeve is rotatably connected to the outer wall of the adjustment frame.
[0009] Furthermore, the rotating assembly includes a rotating wheel rotatably disposed on the outer wall of the rotating sleeve, a rotating disk rotatably disposed on the inner wall of the rotating wheel, and a positioning protrusion disposed on the outer wall of the rotating disk.
[0010] Furthermore, the positioning component includes a fixing block fixedly disposed on the outer wall of the connecting rod, a roller connecting rod rotatably disposed on the outer wall of the fixing block, a connecting assembly fixedly disposed on the inner wall of the roller connecting rod, a limiting block rotatably disposed on the end of the roller connecting rod away from the roller, a roller rotatably disposed on the outer wall of the limiting block, a damping rod fixedly disposed on the outer wall of the limiting block, a compression spring disposed outside the damping rod, and a locking assembly fixedly disposed on the inner wall of the fixing block.
[0011] Furthermore, the connecting assembly includes a connecting ring fixedly disposed on the inner wall of the roller connecting rod, a positioning groove formed on the inner side wall of the connecting ring, and guide grooves symmetrically formed on the outer wall of the connecting ring.
[0012] Furthermore, the locking assembly includes a limiting sleeve fixedly disposed on the inner wall of the fixing block, a movable structure slidably disposed on the outer wall of the limiting sleeve, a pressing wheel disposed on the top outer wall of the movable structure, a guide sleeve slidably disposed on the top outer wall of the movable structure, and a tension spring disposed at the top of the inside of the guide sleeve.
[0013] Furthermore, the movable structure includes a cross rod slidably disposed on the inner wall of the limiting sleeve, a connecting protrusion disposed on the top outer wall of the cross rod, a round rod disposed on the top outer wall of the connecting protrusion, an elastic sheet disposed on the inner wall of the connecting protrusion, and a snap block slidably disposed on the inner wall of the connecting protrusion. The other end of the tension spring is fixedly connected to the top outer wall of the connecting protrusion, and the other end of the elastic sheet is fixedly connected to the outer wall of the snap block.
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The drive component and the adjustment component form a linkage mechanism. When the connecting sleeve approaches, it simultaneously pushes the rotating rod to make the friction block fit against the rotating wheel and pushes the telescopic rod to retract the friction disc. When the connecting sleeve moves away, it simultaneously disconnects the drive power and pops out the friction disc. This mechanically avoids the misoperation of driving without releasing the brake or stopping the slide without braking, thus reducing the safety risks of high-altitude sliding.
[0015] 2. The device improves adaptability by adjusting components. The servo motor drives the bidirectional screw to rotate, which in turn drives the internal threaded sleeve and the movable component to flexibly adjust the spacing. It can adapt to different specifications of I-beams without manual disassembly and replacement of parts. This saves the cost of custom-made special clamping parts and shortens the traditional adjustment time, thereby improving the equipment reuse rate and construction continuity.
[0016] 3. Positioning is achieved through positioning components. When the movable frame moves, it drives the fixed block and roller connecting rod to approach the I-beam. After the rollers are in contact with the side wall, the extrusion roller is pressed and drives the movable structure to move down. The elastic plate pushes the buckle block to automatically engage with the positioning groove of the connecting component. Locking can be completed without manual calibration, which avoids the problem of easy loosening when manually locked, shortens the positioning and debugging time, and improves the lateral stability during the sliding process.
[0017] 4. The damping rod and compression spring of the positioning component form a buffer structure. When the roller part of the roller connecting rod is in contact with the side wall of the I-beam, the damping rod and compression spring can offset the impact force of hard contact, avoid wear and tear on the roller and the side wall of the I-beam due to collision, reduce the probability of component damage, extend the service life of the device and the I-beam, and reduce the later maintenance cost.

Detailed Implementation
[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0021] Example 1, referring to Figure 1 - Figure 4 and Figure 6 The first embodiment of the present invention provides a steel structure roof pre-assembly sliding installation device, including a sliding frame 1, a winch 2 fixedly connected to the top outer wall of the sliding frame 1, a suspension frame 3 symmetrically fixedly connected to the top outer wall of the sliding frame 1, and a limiting wheel 6 fixedly connected to the inside of the sliding frame 1. It also includes an adjustment component 4 slidably connected to the outer wall of the sliding frame 1, a drive component 5 rotatably connected to the outer wall of the adjustment component 4, and a positioning component 7 fixedly connected to the outer wall of the adjustment component 4. The adjustment component 4 includes a servo motor 41 fixedly connected to the inner wall of the sliding frame 1, a bidirectional screw 42 fixedly connected to the output end of the servo motor 41, an internal threaded sleeve 43 fixedly connected to the outer wall of the bidirectional screw 42, a movable component 44 fixedly connected to the outer wall of the internal threaded sleeve 43, and a connecting rod 45 fixedly connected to the inner wall of the movable component 44.
[0022] The driving component 5 includes a DC motor 51 fixedly connected to the inner wall of the sliding frame 1, a linkage rod 52 fixedly connected to the output end of the DC motor 51, a movable groove 53 symmetrically opened on the outer wall of the linkage rod 52, an extension assembly 54 slidably connected to the outer wall of the linkage rod 52, a rotating assembly 55 rotatably connected to the outer wall of the extension assembly 54, a contact wheel 56 rotatably connected to the middle outer wall of the linkage rod 52, a telescopic rod 57 fixedly connected to the side wall of the contact wheel 56, and a friction disc 58 fixedly connected to the other end of the telescopic rod 57; the positioning component 7 is used to move in coordination with the movement of the adjusting component 4 and to clamp and position according to the thickness of the side wall of the I-beam steel, and the driving component 5 moves under clamping and positioning.
[0023] Specifically, during the sliding construction of the pre-assembled steel structure roof, the device first needs to be adapted and adjusted to the I-beam, and then achieve smooth sliding through the linkage control of drive and brake. At the same time, the positioning component 7 enhances the clamping stability, and all parts work together to ensure the roof installation. At this time, the movable component 44 pushes the extension component 54 closer to the rotating wheel 551. The drive component 5 is in the braking state at this time. Since the movable frame 441 is not close to the drive component 5 at this time, the connecting sleeve 541, which is slidably sleeved on the outer wall of the linkage rod 52, is not pushed. When the rotating rod 543 is in motion, the friction block 544 on the outer wall of the rotating rod 543 is not in contact with the inner wall of the rotating wheel 551, so the rotating wheel 551 is difficult to obtain driving force. At the same time, the telescopic rod 57 on the side wall of the contact wheel 56 is in an extended state, which will push the friction disc 58 into the inside of the contact wheel 56, so that the friction disc 58 is in contact with the inner wall of the sliding frame 1. The friction restricts the rotation of the contact wheel 56, forming an initial braking effect, preventing the device from sliding unexpectedly when the roof is not lifted, and solving the safety hazard of traditional devices that are prone to slippage due to the lack of pre-braking design.
[0024] Reference Figure 1 - Figure 5 The movable component 44 includes a movable frame 441 slidably connected to the inner wall of the sliding frame 1, an adjustment frame 442 symmetrically fixedly connected to the outer wall of the movable frame 441, a limiting groove 443 opened in the inner wall of the movable frame 441, the inner wall of the movable frame 441 being rotatably connected to the outer wall of the limiting wheel 6 through the limiting groove 443, the inner wall of the movable frame 441 being fixedly connected to the outer wall of the connecting rod 45, and the outer wall of the movable frame 441 being fixedly connected to the outer wall of the internal threaded sleeve 43.
[0025] Specifically, when the roof is lifted by the winch 2 and the suspension frame 3, the servo motor 41 of the adjustment component 4 is started, and its output end drives the bidirectional screw 42 to rotate, so that the inner threaded sleeve 43 on the outer wall of the bidirectional screw 42 moves along the screw axis, thereby pulling the movable component 44 which is fixedly connected to the inner threaded sleeve 43. The movable frame 441 drives the positioning component 7 on the push connecting rod 45 to clamp it. The movable component 44 can change the spacing of the movable frame 441, thereby realizing the adaptation to I-beams of different specifications.
[0026] Reference Figure 1 - Figure 8 The extension assembly 54 includes a connecting sleeve 541 slidably connected to the outer wall of the linkage rod 52, a sliding protrusion 542 fixedly connected to the inner side wall of the connecting sleeve 541, a rotating rod 543 rotatably connected to the outer wall of the connecting sleeve 541, a friction block 544 rotatably connected to the outer wall of the rotating rod 543, a groove 545 formed on the outer wall of the friction block 544, and a rotating sleeve 546 rotatably connected to the inner wall of the connecting sleeve 541. The outer wall of the connecting sleeve 541 is rotatably connected to the outer wall of the adjustment frame 442.
[0027] The rotating assembly 55 includes a rotating wheel 551 rotatably connected to the outer wall of the rotating sleeve 546, a rotating disk 552 rotatably connected to the inner wall of the rotating wheel 551, and a positioning protrusion 553 fixedly connected to the outer wall of the rotating disk 552.
[0028] Specifically, after the winch 2 and the suspension frame 3 smoothly lift the roof to the preset height, the servo motor 41 drives the bidirectional screw 42 to rotate. The inner threaded sleeve 43 drives the limiting groove 443 of the movable frame 441 to move along the axial direction of the limiting wheel 6, and then horizontally approaches the center of the I-beam. Simultaneously, the rotating component 55 of the drive component 5 changes to the sliding mode. When the movable frame 441 moves, it will drive the extension component 54 to move through the adjustment frame 442. At this time, the connecting sleeve 541 slides along the outer wall of the linkage rod 52. The sliding protrusion 542 on the inner side wall of the connecting sleeve 541 will be guided along the movable groove 53 on the outer wall of the linkage rod 52. During the movement of the connecting sleeve 541, it will push the rotating rod 543 to swing, causing the friction block 544 on the outer wall of the rotating rod 543 to slide. The friction block 544 slides on the positioning protrusion 553 on the rotating disk 552 through the sliding groove 545 on its own outer wall, and finally fits against the inner wall of the rotating wheel 551. At this time, the DC motor 51 starts, driving the linkage rod 52 to rotate. Through the friction between the friction block 544 and the inner wall of the rotating wheel 551, the rotating wheel 551 is driven to rotate synchronously. The rotating wheel 551 thus becomes the driving wheel that provides power to the device. At the same time, as the connecting sleeve 541 approaches the contact wheel 56, it pushes the telescopic rod 57 to retract, pulling the friction disc 58 into the contact wheel 56. At this time, the rotating sleeve 546 pushes the friction disc 58, causing the friction disc 58 to retract into the contact wheel 56. While reducing the friction area, due to the relative rotation of the rotating sleeve 546 and the connecting sleeve 541, the contact wheel 56 can hardly affect the driving process of the rotating wheel 551, thus releasing the brake. This linkage structure setting avoids the misoperation of driving without releasing the brake or stopping the slide without braking from a mechanical point of view, thereby reducing the accidental risks during the sliding process, and is especially suitable for the safety construction requirements of high-altitude roofs.
[0029] Example 2, refer to Figure 1 - Figure 9 This is the second embodiment of the present invention, which differs from the first embodiment in that: the positioning component 7 includes a fixing block 71 fixedly connected to the outer wall of the connecting rod 45, a roller connecting rod 73 rotatably connected to the outer wall of the fixing block 71, a connecting assembly 72 fixedly connected to the inner wall of the roller connecting rod 73, a limiting block 74 rotatably connected to the end of the roller connecting rod 73 away from the roller, a roller 75 rotatably connected to the outer wall of the limiting block 74, a damping rod 77 fixedly connected to the outer wall of the limiting block 74, a compression spring 78 sleeved on the outside of the damping rod 77, and a locking assembly 76 fixedly connected to the inner wall of the fixing block 71.
[0030] Specifically, while the adjusting component 4 drives the movable frame 441 to move, the positioning component 7 simultaneously clamps and positions the side wall of the I-beam, further ensuring sliding stability. When the movable frame 441 moves, it drives the fixed block 71 to move through the connecting rod 45. The fixed block 71 pulls the roller connecting rod 73 close to the side wall of the I-beam until the roller 75 at the end of the roller connecting rod 73 is in contact with the side wall of the I-beam. At this time, the limiting block 74 and the roller 75 leave the movable frame 441. The damping rod 77 on the inner wall of the roller connecting rod 73 and the compression spring 78 outside the damping rod 77 will have a buffering effect, avoiding damage to the components caused by hard contact between the roller 75 and the side wall of the I-beam.
[0031] Reference Figure 1 - Figure 9 and Figure 11 The connecting component 72 includes a connecting ring 721 fixedly connected to the inner wall of the roller connecting rod 73, a positioning groove 722 opened in the inner side wall of the connecting ring 721, and guide grooves 723 symmetrically opened in the outer wall of the connecting ring 721.
[0032] Specifically, when the connecting protrusion 7632 moves to the empty position between the limiting sleeve 761 and the guide sleeve 762, the elastic sheet 7634 on the inner wall of the connecting protrusion 7632 will squeeze out the snap-fit block 7635. The snap-fit block 7635 will be guided by the guide groove 723 of the connecting assembly 72 on the inner wall of the roller connecting rod 73 and snap into the positioning groove 722 of the connecting assembly 72.
[0033] Reference Figure 1 - Figure 10 The locking component 76 includes a limiting sleeve 761 fixedly connected to the inner wall of the fixing block 71, a movable structure 763 slidably connected to the outer wall of the limiting sleeve 761, a pressing wheel 765 fixedly connected to the top outer wall of the movable structure 763, a guide sleeve 762 slidably connected to the top outer wall of the movable structure 763, and a tension spring 764 fixedly connected to the inner top end of the guide sleeve 762.
[0034] Specifically, the pressing wheel 765 of the locking assembly 76 in the positioning component 7 contacts the inclined surfaces on both sides of the top of the I-beam. After being pressed by the inclined surfaces, the pressing wheel 765 drives the movable structure 763 to move downward. The movable structure 763 includes a cross rod 7631, a connecting protrusion 7632, and a round rod 7633. During the downward movement, the cross rod 7631 slides along the inner wall of the limiting sleeve 761 of the locking assembly 76, while simultaneously pulling the tension spring 764 of the locking assembly 76. The top end of the tension spring 764 is connected to the top end of the guide sleeve 762 inside the locking assembly 76. The remaining structures are the same as those in Embodiment 1.
[0035] Example 3, referring to Figure 1 - Figure 12This is the third embodiment of the present invention, which differs from the second embodiment in that: the movable structure 763 includes a cross rod 7631 slidably connected to the inner wall of the limiting sleeve 761, a connecting protrusion 7632 fixedly connected to the top outer wall of the cross rod 7631, a round rod 7633 fixedly connected to the top outer wall of the connecting protrusion 7632, an elastic piece 7634 fixedly connected to the inner wall of the connecting protrusion 7632, and a latching block 7635 slidably connected to the inner wall of the connecting protrusion 7632. The other end of the tension spring 764 is fixedly connected to the top outer wall of the connecting protrusion 7632, and the other end of the elastic piece 7634 is fixedly connected to the outer wall of the latching block 7635.
[0036] Specifically, when the connecting protrusion 7632 moves to the empty position between the limiting sleeve 761 and the guide sleeve 762, the elastic piece 7634 on the inner wall of the connecting protrusion 7632 will push out the latching block 7635. Guided by the guide groove 723 on the inner wall of the roller connecting rod 73, the latching block 7635 will engage with the positioning groove 722 of the connecting assembly 72 (the connecting assembly 72 is a connecting ring 721, and both the positioning groove 722 and the guide groove 723 are formed on the connecting ring 721). Simultaneously... The rod 7631 can limit the swaying of the movable structure 763 and achieve automatic locking of the connecting component 72. The multiple constraint structure, consisting of the roller clamping the side wall of the roller connecting rod 73, the limiting wheel 6 limiting the top end, and the locking component 76 securing it, can counteract the lateral impact force on the roof during sliding, reduce lateral displacement of the device, and avoid the problems of track biting and displacement that easily occur in traditional sliding, thus ensuring sliding accuracy. Furthermore, this automatic locking design eliminates the need for manual calibration, shortening the single positioning and debugging time and reducing labor costs. The remaining structures are the same as in Embodiment 2.
[0037] Based on embodiments 1-3, the working principle of this invention is as follows: This device ensures the sliding installation of the steel structure roof through adaptation adjustment, drive braking linkage, and positioning clamping coordination. Before lifting the roof, the servo motor 41 of the adjustment component 4 is started, which drives the bidirectional screw 42 to rotate, so that the inner threaded sleeve 43 pulls the movable component 44 to adjust the spacing, adapting to different specifications of I-beams without the need for customized special parts; at this time, the drive component 5 is in the braking state, the connecting sleeve 541 does not push the rotating rod 543, the friction block 544 does not contact the rotating wheel 551, the rotating wheel 551 has no power, and the telescopic rod 57 of the contact wheel 56 pushes out the friction disc 58 to contact the sliding frame 1, forming a brake to prevent accidental slippage.
[0038] After the roof is hoisted to the preset height, the servo motor 41 reverses its direction, and the movable frame 441 moves along the limit wheel 6 to approach the I-beam. The drive component 5 is switched to sliding mode, and the movable frame 441 drives the connecting sleeve 541 to slide along the linkage rod 52, pushing the rotating rod 543 to make the friction block 544 fit against the rotating wheel 551. The DC motor 51 starts and drives the linkage rod 52 to rotate, driving the rotating wheel 551 to provide power. At the same time, the connecting sleeve 541 pushes the telescopic rod 57 to retract, and the friction disc 58 is retracted to release the brake, avoiding misoperation and meeting the high-altitude safety requirements.
[0039] When the adjusting component 4 is driven, the positioning component 7 clamps synchronously. The movable frame 441 drives the fixed block 71 through the connecting rod 45, so that the roller 75 of the roller connecting rod 73 fits against the side wall of the I-beam. The damping rod 77 and the compression spring 78 buffer and prevent damage. The pressing wheel 765 is pressed and drives the movable structure 763 to move down. The elastic plate 7634 pushes out the buckle block 7635 and snaps into the positioning groove 722 of the connecting component 72 to achieve automatic locking. Multiple constraints offset the lateral impact force, avoid rail biting and deviation, ensure accuracy and reduce labor costs.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
