Description

Technical Field

[0001] This utility model relates to the field of steel structures, and in particular to a quick positioning and installation device for steel structure bolts. Background Technology

[0002] Steel structure refers to a building structure system constructed primarily of steel. It is widely used in engineering fields such as buildings, bridges, towers, factories, and high-rise buildings.

[0003] The steel structure bolt quick positioning and installation tool is a special tool used for steel structure construction.

[0004] Existing quick-positioning installers for steel structure bolts have the following shortcomings:

[0005] As the core load-bearing components of steel structure buildings, the connection quality and assembly efficiency of steel bridge components directly affect the overall project progress and structural safety. Currently, steel bridge components are mostly connected using flange docking. During flange docking, bolt installation often requires the assistance of a positioning installer. However, in actual use, the positioning installer in the existing technology still relies heavily on manual operation to complete the alignment process. Operators need to repeatedly adjust the position of the component and the angle of the installer, and calibrate the flange bolt hole position by visual observation or simple measuring tools to ensure that the bolts can be smoothly inserted. The entire alignment process not only requires a high level of experience from the operators, but also often requires multiple trial and error adjustments for each alignment, which is time-consuming and seriously slows down the bolt installation rhythm, resulting in low overall assembly efficiency of steel bridge components. Utility Model Content

[0006] This invention reduces reliance on operational experience and significantly shortens the alignment time per cycle, thereby solving the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a quick positioning and installation device for steel structure bolts, including a positioning mechanism, the outer wall of which is provided with a connecting mechanism; the positioning mechanism includes a first connecting plate and a second connecting plate, the top of the first connecting plate and the second connecting plate are provided with a set of semi-circular grooves, the inner walls of the semi-circular grooves are slidably connected with movable rods, the top of the movable rods are fixedly connected with a set of semi-gears, the inner walls of the semi-gears are fixedly connected with a set of semi-circular disks, the top of the semi-circular disks are provided with through holes, the inner walls of the semi-circular disks are slidably connected with a set of I-beams, and a fixing plate is fixedly connected to one side of the top of the first connecting plate. Through the above components, it is ensured that the bolts can be accurately aligned with the flange threaded holes, greatly reducing the difficulty of manual alignment.

[0008] Preferably, a set of connecting bolts is provided through the threads on both sides of the first connecting plate and the second connecting plate. The connecting bolts can firmly connect the first connecting plate and the second connecting plate into one unit, while ensuring that the two are stably positioned on the flange.

[0009] Preferably, a drive gear is movably inserted into the top of the first connecting plate. The outer wall of the drive gear is slidably connected to the inner wall of the fixed plate. The drive gear meshes with the half gear. When the drive gear meshes with the half gear, the operator only needs to rotate the drive gear to drive the half gear to rotate, thereby adjusting the angle and position of the semi-disc, realizing the quick alignment of the through hole and the flange thread hole, replacing the tedious operation of manually adjusting the semi-disc.

[0010] Preferably, a positioning rod is provided through the top of the drive gear, and positioning holes are provided on the top of each fixing plate. The inner wall of the positioning hole is slidably connected to the outer wall of the positioning rod. When the drive gear drives the half gear and the half disk to a suitable position, so that the through hole of the half disk is aligned with the threaded hole of the flange, the positioning rod is inserted into the positioning hole. This can quickly lock the position of the drive gear and prevent the drive gear from rotating due to vibration, accidental collision, etc. during the bolt insertion process, which would cause the half disk to shift. This ensures a stable positioning state and ensures that the bolt can be smoothly inserted into the threaded hole.

[0011] Preferably, the inner walls of the first connecting plate and the second connecting plate are provided with a set of sliding grooves, and the inner walls of the sliding grooves are fixedly connected with guide rods. The outer walls of the guide rods are slidably connected with a set of arc-shaped clamps. The guide rods and sliding grooves can guide the translation of the arc-shaped clamps.

[0012] Preferably, a set of anti-slip pads is fixedly connected to the inner wall of the arc-shaped clamp, and springs are fixedly connected to the inner walls of the first connecting plate and the second connecting plate. One end of the spring is fixedly connected to the inner wall of the first connecting plate and the second connecting plate, and the other end of the first connecting plate and the second connecting plate is fixedly connected to the outer wall of the arc-shaped clamp. The springs are elastic and can play a buffering role when the arc-shaped clamp clamps the flange or is subjected to external impact, thereby reducing the rigid compression of the outer wall of the flange by the arc-shaped clamp and avoiding damage to the flange surface due to excessive clamping force.

[0013] Preferably, the connecting mechanism includes a flange, and the outer wall of the flange is provided with threaded holes. The threaded holes on the flange are the final installation positions of the bolts. Using the threaded holes as the positioning reference, by adjusting the various components of the installer, the semi-circular through hole and the threaded hole are precisely aligned, providing a clear and accurate target position for bolt installation, reducing the time spent manually searching for and aligning the threaded holes, thereby improving installation efficiency.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, the first and second connecting plates in the positioning mechanism provide stable support for the overall structure. The sliding fit between the semicircular groove and the movable rod, as well as the meshing transmission between the half gear and the drive gear, allow the operator to quickly adjust the angle of the semicircular disk simply by rotating the drive gear, so that the through hole on it is precisely aligned with the threaded hole of the flange. This not only completely replaces the tedious process of repeated trial and error alignment in traditional manual methods and reduces the reliance on operating experience, but also significantly shortens the alignment time per operation. It effectively solves the problem of low bolt installation efficiency when connecting flanges of steel bridge components. At the same time, the I-beam can connect the two semicircular disks into one unit, ensuring that the subsequent two semicircular disks and the corresponding half gear can rotate normally through the drive gear, thereby ensuring the smooth progress of the alignment operation.

[0016] 2. In this utility model, the connecting bolts can firmly connect the first connecting plate and the second connecting plate, ensuring that the installer is stably fixed to the flange, while facilitating disassembly and assembly. The inner wall of the arc-shaped clamp is equipped with an anti-slip pad and a spring structure, which not only enhances the clamping stability of the arc-shaped clamp on the flange and prevents the installer from shifting during operation, but also reduces the rigid compression of the outer wall of the flange by the arc-shaped clamp through the buffering effect of the spring, effectively avoiding damage to its surface. In addition, the matching design of the positioning rod and the positioning hole can be used to lock the position of the drive gear, preventing positioning failure due to vibration or accidental collision during bolt insertion, thereby improving the safety and accuracy of the overall operation.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a quick positioning and installation device for steel structure bolts, including a positioning mechanism 1, with a connecting mechanism 2 provided on the outer wall of the positioning mechanism 1; the positioning mechanism 1 includes a first connecting plate 101 and a second connecting plate 109, the top of the first connecting plate 101 and the second connecting plate 109 are provided with a set of semi-circular grooves 115, the inner wall of the semi-circular grooves 115 is slidably connected with a movable rod 117, the top of the movable rod 117 is fixedly connected with a set of semi-gears 106, the inner wall of the semi-gears 106 is fixedly connected with a set of semi-circular disks 105, the top of the semi-circular disks 105 are provided with through holes 116, the inner wall of the semi-circular disks 105 is slidably connected with a set of I-beams 107, and a fixing plate 102 is fixedly connected to one side of the top of the first connecting plate 101. Through the above components, it is ensured that the bolt can be accurately aligned with the threaded hole 202 of the flange 201, greatly reducing the difficulty of manual alignment.

[0026] like Figure 2 As shown, a set of connecting bolts 108 are threaded through the front and back sides of the first connecting plate 101 and the second connecting plate 109. The connecting bolts 108 can firmly connect the first connecting plate 101 and the second connecting plate 109 into one unit, while ensuring that the two are stably positioned on the flange 201.

[0027] like Figure 4As shown, a drive gear 118 is movably inserted into the top of the first connecting plate 101. The outer wall of the drive gear 118 is slidably connected to the inner wall of the fixed plate 102. The drive gear 118 is meshed with the half gear 106. The operator only needs to rotate the drive gear 118 to drive the half gear 106 to rotate, thereby adjusting the angle and position of the semi-circular disk 105, so as to achieve quick alignment of the through hole 116 and the threaded hole 202 of the flange 201, replacing the tedious operation of manually adjusting the semi-circular disk 105.

[0028] like Figure 2 As shown, a positioning rod 103 is provided through the top of the drive gear 118, and positioning holes 104 are provided on the top of the fixing plate 102. The inner wall of the positioning hole 104 is slidably connected to the outer wall of the positioning rod 103. When the drive gear 118 drives the half gear 106 and the semi-disc 105 to adjust to the appropriate position, so that the through hole 116 of the semi-disc 105 is aligned with the threaded hole 202 of the flange 201, the positioning rod 103 is inserted into the positioning hole 104. This can quickly lock the position of the drive gear 118 and prevent the drive gear 118 from rotating due to vibration, accidental collision, etc. during the bolt insertion process, which would cause the semi-disc 105 to shift. This ensures a stable positioning state and ensures that the bolt can be smoothly inserted into the threaded hole 202.

[0029] like Figure 3 As shown, a set of sliding grooves 113 are provided on the inner walls of the first connecting plate 101 and the second connecting plate 109. Guide rods 114 are fixedly connected to the inner walls of the sliding grooves 113. A set of arc-shaped clamps 111 are slidably connected to the outer walls of the guide rods 114. The guide rods 114 and the sliding grooves 113 can guide the translation of the arc-shaped clamps 111.

[0030] like Figure 3 As shown, a set of anti-slip pads 112 are fixedly connected to the inner wall of the arc-shaped clamp 111. Springs 110 are fixedly connected to the inner walls of the first connecting plate 101 and the second connecting plate 109. One end of the spring 110 is fixedly connected to the inner wall of the first connecting plate 101 and the second connecting plate 109, and the other end of the first connecting plate 101 and the second connecting plate 109 is fixedly connected to the outer wall of the arc-shaped clamp 111. The spring 110 is elastic and can play a buffering role when the arc-shaped clamp 111 clamps the flange 201 or is subjected to external impact, thereby reducing the rigid compression of the outer wall of the flange 201 by the arc-shaped clamp 111 and avoiding damage to the surface of the flange 201 due to excessive clamping force.

[0031] like Figure 5As shown, the connecting mechanism 2 includes a flange 201. The outer wall of the flange 201 is provided with threaded holes 202. The threaded holes 202 on the flange 201 are the final installation positions of the bolts. Using the threaded holes 202 as the positioning reference, by adjusting the components of the installer, the through holes 116 of the semicircular disc 105 are precisely aligned with the threaded holes 202, providing a clear and accurate target position for bolt installation, reducing the time spent manually searching for and aligning the threaded holes 202, thereby improving installation efficiency.

[0032] The usage and working principle of this device are as follows: First, place the movable rods 117 on the two half-gears 106 into the semi-circular grooves 115 at the top of the first connecting plate 101 and the second connecting plate 109, and make the half-gears 106 mesh with the drive gear 118. At the same time, place the two I-beams 107 into the two semi-circular disks 105 respectively to form an integral structure. Then, place the first connecting plate 101 and the second connecting plate 109 on both sides of the flange 201 and connect and fix them with the connecting bolts 108 to make them firmly integrated. Using the arc-shaped clamp 111 in conjunction with the spring 110 and the anti-slip pad 112, clamp the entire installer onto the flange 201 to ensure stable clamping without damaging the surface of the flange 201. Next, the operator rotates the drive gear 118. Because the drive gear 118 and the half-gears 106... The meshing drives the half gear 106 and the semi-circular disk 105 fixed to its inner wall to rotate synchronously. During this process, the movable rod 117 slides in the semi-circular groove 115 to assist in adjusting the angle and position of the semi-circular disk 105. When the through hole 116 at the top of the semi-circular disk 105 is precisely aligned with the threaded hole 202 on the outer wall of the flange 201, the positioning rod 103 is inserted into the positioning hole 104 at the top of the fixing plate 102 to lock the position of the drive gear 118 and prevent the semi-circular disk 105 from shifting during the subsequent bolt installation. Finally, the bolt is passed through the through hole 116 of the semi-circular disk 105 and screwed into the threaded hole 202 on the flange 201 to complete the quick positioning and installation of the bolt. After installation, the connecting bolt 108 is unscrewed to separate the first connecting plate 101 from the second connecting plate 109, thereby completing the separation of the installer from the flange 201.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
