Description

Technical Field

[0001] This utility model relates to the field of steel structure construction equipment, and in particular to an installation and alignment tool for steel structure construction. Background Technology

[0002] Steel structures are widely used in many fields, especially in the construction industry. It is often necessary to assemble and connect two steel structural components, and then fix the steel structure with bolts and welding. Because the construction height of steel structures is relatively high, the connection of some steel structures will be carried out at high altitude. The usual practice is to use a crane to lift one section of steel structure and connect it to another section of steel structure.

[0003] Whether using bolts or welding for fixing, the steel structure must be kept in a neat and aligned state. If the two steel structures are not aligned, the bolts will not be able to connect with the threaded holes on the steel beams when using bolts for fixing; large errors will occur during welding, thus affecting the connection quality of the steel beams.

[0004] Currently, the connection and fixing of steel structure beams is mostly done manually, lacking connection and positioning devices. Operators need to fine-tune the position of the steel structure with crowbars while suspended in the air. Their unstable center of gravity can easily lead to falls. In addition, the hoisted steel structure components are easily displaced by wind and the swing of the slings. Manual straightening is difficult to compensate for the swaying in real time, and repeated hoisting and correction are often required, which prolongs the time spent working at height. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an installation alignment tool for steel structure construction.

[0006] The technical solution includes a fixed frame, on which two guide columns are fixedly mounted. The two guide columns are fixedly connected by a connecting plate. A lead screw is provided in the middle of the two guide columns. The lead screw is rotatably connected to the fixed frame and the connecting plate respectively.

[0007] A movable frame is slidably mounted on the two guide columns, and the movable frame is threadedly connected to the lead screw.

[0008] The upper ends of both the fixed frame and the movable frame are rotatably equipped with several connecting rods, and the movable ends of the connecting rods on the same side are rotatably connected by an upper clamping rod.

One of the active bevel gears is rotatably connected to the fixed frame, and the other is rotatably connected to the movable frame. The active bevel gear rotatably connected to the movable frame is axially slidably fixed radially to the transmission rod.

[0010] One side of each of the driving bevel gears meshes with a driven bevel gear, and a screw is fixedly installed on the side of the driven bevel gear away from the teeth;

[0011] A nut is rotatably mounted in the middle of one of the connecting rods on the same side, and the nut is threadedly connected to an adjacent screw.

[0014] Preferably, a handle is fixedly provided at one end of the lead screw.

[0015] The beneficial effects of the technical solution provided by this utility model embodiment are: 1. The two upper clamping rods form a symmetrical four-point fixing structure with the fixed frame and the movable frame respectively, which can be applied to the multi-point clamping of I-beams, square steel, H-beam columns and round steel, ensuring that the contact stress is evenly distributed when the steel structure is aligned.

[0026] Example 1

[0027] See Figures 1 to 3 This utility model provides an installation alignment tool for steel structure construction, including a fixed frame 1, two guide columns 2 fixedly installed on the fixed frame 1, the two guide columns 2 being fixedly connected by a connecting plate 3, and a screw rod 4 installed in the middle of the two guide columns 2, the screw rod 4 being rotatably connected to the fixed frame 1 and the connecting plate 3 respectively.

[0028] A movable frame 5 is slidably mounted on the two guide columns 2, and the movable frame 5 is threadedly connected to the lead screw 4.

[0029] Several connecting rods 6 are rotatably installed at the upper ends of both the fixed frame 1 and the movable frame 5, and the movable ends of the connecting rods 6 on the same side are rotatably connected by an upper clamping rod 7.

[0030] Place the fixing frame 1 at the bottom of the steel structure component 18 to be aligned, so that the upper surface of the fixing frame 1 abuts against the lower surface of the steel structure component 18. Turn the handle 17 to drive the lead screw 4 to rotate. The lead screw 4 drives the movable frame 5 to slide along the guide column 2 towards the fixing frame 1 until the upper surface of the movable frame 5 abuts against the lower surface of the steel structure component 18. The two sides of the steel structure component 18 are clamped by several connecting rods 6 that are rotatably set on the fixing frame 1 and the movable frame 5.

[0031] Then, the upper clamping rods 7 on both sides are pushed to open and close, so that the upper clamping rods 7 abut against and clamp the upper surface of the steel structure component 18, and finally realize the alignment and fixation of the steel structure component 18.

[0032] The two upper clamping rods 7 form a symmetrical four-point fixing structure with the fixed frame 1 and the movable frame 5 respectively, which can be used for multi-point clamping of I-beams, square steel, H-beam columns and round steel, ensuring that the contact stress is evenly distributed when the steel structure is aligned.

[0033] Under the action of the connecting rod 6, the upper clamping rod 7 can be adjusted to be positioned relative to the fixed frame 1 and the movable frame 5. At the same time, the distance between the movable frame 5 and the fixed frame 1 is adjustable to accommodate different specifications of I-beams, square steel, H-beam columns and round steel, thereby improving the versatility of the device.

[0034] A transmission rod 8 is rotatably mounted on one side of the fixed frame 1. Two active bevel gears 9 are slidably mounted on the transmission rod 8. One of the active bevel gears 9 is rotatably connected to the fixed frame 1, and the other is rotatably connected to the movable frame 5. The active bevel gear 9 rotatably connected to the movable frame 5 is axially slidably fixed radially to the transmission rod 8.

[0035] One side of each driving bevel gear 9 meshes with a driven bevel gear 10. A gear carrier is provided between the driving bevel gear 9 and the driven bevel gear 10. The gear carrier can ensure that the driving bevel gear 9 and the driven bevel gear 10 are always in a meshing state. A screw 11 is fixedly provided on the side of the driven bevel gear 10 away from the teeth.

[0036] A nut 12 is rotatably mounted in the middle of one of the connecting rods 6 on the same side, and the nut 12 is threadedly connected to an adjacent screw 11.

[0037] After the initial clamping of the steel structure component 18 is completed, the transmission rod 8 is rotated. The transmission rod 8 drives the two active bevel gears 9 to rotate synchronously. Each active bevel gear 9 drives the driven bevel gear 10 that meshes with it to rotate, so that the screw 11 on the driven bevel gear 10 rotates accordingly.

[0038] The screw 11 and the nut 12 in the middle of the corresponding connecting rod 6 form a threaded transmission. When the screw 11 rotates, it pushes the nut 12 to move along its axis, which drives the connecting rod 6 to swing around the rotation fulcrum of the fixed frame 1 or the movable frame 5, so that the upper clamping rod 7 abuts against and clamps the upper surface of the steel structure component 18, and finally realizes the alignment and fixation of the steel structure component 18.

[0039] The double-sided symmetrical bevel gear transmission structure allows the adjustment of the connecting rods 6 on both sides to be carried out synchronously, preventing component misalignment caused by unilateral force application and improving alignment stability.

[0040] A ratchet 13 is fixedly mounted on the rod body of the transmission rod 8, and a limiting pawl 14 is rotatably mounted on the fixed frame 1. A torsion spring is provided between the limiting pawl 14 and the fixed frame 1. The torsion spring enables the limiting pawl 14 and the ratchet 13 to always cooperate.

[0041] When the transmission rod 8 is rotated, the limiting pawl 14 engages with the tooth groove of the ratchet 13 to form a self-locking mechanism, preventing the transmission rod 8 from rotating in the opposite direction. This avoids the clamping force from loosening due to accidental reversal of the transmission rod 8, ensuring alignment stability. When it is necessary to unlock, the limiting pawl 14 can be manually moved to disengage it from the tooth groove of the ratchet 13, and the transmission rod 8 can then be rotated in the opposite direction.

[0042] The two upper clamping rods 7, the fixed frame 1, and the movable frame 5 form a four-point fixation.

[0043] A wrench 15 is rotatably mounted on the rod body of the transmission rod 8. A drive pawl 16 is rotatably mounted on the wrench 15. A torsion spring is provided between the drive pawl 16 and the fixed frame 1. The torsion spring enables the drive pawl 16 to always engage with the ratchet 13.

[0044] By continuously swinging the wrench 15 under the action of the driving pawl 16, the user can drive the transmission rod 8 to rotate, which reduces the torque required for the transmission rod 8 to rotate and saves more effort.

[0045] A handle 17 is fixedly installed at one end of the lead screw 4.

[0046] When using this utility model, the fixing frame 1 is placed at the bottom of the steel structure component 18 to be aligned, so that the upper surface of the fixing frame 1 abuts against the lower surface of the steel structure component 18. The handle 17 is turned to drive the lead screw 4 to rotate. The lead screw 4 drives the movable frame 5 to slide along the guide column 2 towards the fixing frame 1 until the upper surface of the movable frame 5 abuts against the lower surface of the steel structure component 18. The two sides of the steel structure component 18 are clamped by several connecting rods 6 that are rotatably set on the fixing frame 1 and the movable frame 5.

[0047] After the initial clamping of the steel structure component 18 is completed, the transmission rod 8 is rotated. The transmission rod 8 drives the two active bevel gears 9 to rotate synchronously. Each active bevel gear 9 drives the driven bevel gear 10 that meshes with it to rotate, so that the screw 11 on the driven bevel gear 10 rotates accordingly.

[0048] The screw 11 and the nut 12 in the middle of the corresponding connecting rod 6 form a threaded transmission. When the screw 11 rotates, it pushes the nut 12 to move along its axis, causing the connecting rod 6 to swing around the rotation fulcrum of the fixed frame 1 or the movable frame 5, so that the upper clamping rod 7 abuts against and clamps the upper surface of the steel structure component 18, and finally realizes the alignment and fixation of the steel structure component 18.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
