Description

Technical Field

[0001] The present application relates to the technical field of building steel structure construction tools, and more specifically, to a nut disassembly and assembly tool. Background Art

[0002] During steel structure construction, bolts are frequently installed and removed. When using a spanner or ring wrench to remove bolts, the wrench can easily slip, even causing the cap or nut to round off, making removal difficult. Some bolts are larger in diameter, ranging from M16, M22, and M30. Removal requires a variety of wrenches of varying sizes, limiting versatility and requiring maintenance personnel to carry a variety of wrenches, which is inconvenient. In actual operations, it's also common to find that some bolts and nuts rust in humid environments, making removal difficult and time-consuming, often requiring gas welding to cut and remove the nuts. Summary of the Invention

Figure 2 Shown Figure 1 Schematic diagram of the cross-section structure along the AA direction, Figure 3 Shown Figure 1 Schematic diagram of the cross-sectional structure along the BB direction.

[0033] Please refer to Figures 1 to 3 , an embodiment of the present application provides a nut installation and removal tool, including a bracket, a driving assembly and a rotating assembly.

[0034] The bracket includes a steel pipe 110 and six connecting plates 120, one end of each of the six connecting plates 120 is fixedly connected to the steel pipe 110;

[0035] The drive assembly includes six drive units 210, each of which includes a drive screw 211 and a movable nut 212. The movable nut 212 is threadedly connected to the drive screw 211. The six drive screws 211 are evenly distributed on the outer circumference of the steel pipe 110 in a circular form. The axis of each drive screw 211 is perpendicular to the axis of the steel pipe 110. A constraint structure is formed between the first end of each drive screw 211 and the steel pipe 110 to limit the axial movement of the drive screw 211 and allow the drive screw 211 to rotate about its own axis relative to the steel pipe 110.

[0036] The rotating assembly includes six swing plates 310 and claw clamps 320. The top of each swing plate 310 is hinged to a movable nut 212, and the bottom of each swing plate 310 is correspondingly connected to a claw clamp 320. Each swing plate 310 is correspondingly hinged to the other end of a connecting plate 120. Each claw clamp 320 is used to abut against the side of the nut 10 to be disassembled or to clamp at the connecting angle position of the adjacent side of the nut 10 to be disassembled.

[0037] When in use, when operating the six driving units 210 of the driving assembly, specifically, in each driving unit 210, the driving screw 211 is rotated. Because a constraint structure is formed between the steel pipe 110 and the first end of each driving screw 211 to limit the driving screw 211 from moving along its own axial direction and allow the driving screw 211 to rotate around its own axis relative to the steel pipe 110, the rotating driving screw 211 will drive the moving nut 212 to move along the axial direction, and the moving nut 212 can drive the top of the swing plate 310 connected thereto to move, and each swing plate 310 is hinged to the other end of a connecting plate 120. Therefore, when the top of the swing plate 310 moves, the swing plate 310 can rotate around the hinge axis between itself and the corresponding connecting plate 120, and the bottom of each swing plate 310 can drive the corresponding claw clamp 320 to move until the claw clamp 320 is in contact with the to-be-disassembled part. When the cam 212 is in the unlock state, the cam 212 is unlocked and the cam 213 is unlocked, so that the cam 212 can be unlocked and the cam 213 can be unlocked. It should be noted that when the driving bolt drives the movable nut 212 toward the steel pipe 110, the swing plate 310 drives the claw clamp 320 away from the steel pipe 110, and vice versa. Furthermore, when this embodiment assists in the installation of the nut 10 to be disassembled, the nut 10 to be disassembled is already pre-connected to the corresponding screw. During further tightening of the nut 10 to be disassembled, the nut installation and disassembly tool provided in this embodiment can be used to clamp the nut 10 to be disassembled and apply rotational force until the nut 10 to be disassembled reaches the predetermined tightening torque or installation position, ensuring a secure connection between the nut and the screw.

[0038] The nut installation and removal tool provided in this embodiment can be used to remove and assist in the installation of nuts of various specifications, and can quickly and conveniently remove rusted nuts. It is particularly capable of operating in scenarios where the space around the nuts is narrow, thereby reducing the intensity of manual operation and improving the efficiency and accuracy of nut installation.

[0039] See also Figure 1In some embodiments, each drive unit 210 further includes a drive head 213, which is fixedly connected to the end of the drive screw 211 away from the hexagonal steel tube 110. In a specific implementation, the drive head 213 can have a hexagonal head structure. In this way, the drive head 213 and the drive screw 211 can use ordinary commercially available bolts, using the bolt head (such as a hexagonal head, a cross-slot head, etc.) as the drive interface, eliminating the need for custom processing and significantly reducing component procurement costs and lead times. In this embodiment, when in use, the drive head 213 can increase the operability of the drive screw 211, and the drive screw 211 can be driven to rotate by rotating the drive head 213.

[0040] See also Figure 1 In some embodiments, a rotating handle 130 is provided at the top of the steel pipe 110 .

[0041] In specific implementation, the rotating handle 130 can adopt a round grip or a cross-shaped, L-shaped, "I"-shaped handle structure, and its surface is provided with anti-slip patterns (such as knurling, rubber wrapping, etc.) to facilitate the operator to hold and apply force.

[0042] In this embodiment, the entire tool can be easily lifted or moved by holding the rotating handle 130. When the steel pipe 110 needs to be manually driven to rotate, the rotating handle 130 can be used as a force point to drive the steel pipe 110 and the drive screw 211 to rotate synchronously through manpower, thereby realizing the nut installation and removal function.

[0043] See also Figure 1 and Figure 2 In some embodiments, the cross-sectional outer contour of the steel tube 110 is a regular hexagon, and the first end of each drive screw 211 abuts against a corresponding side surface of the steel tube 110. In this embodiment, through the end surface contact constraint between the regular hexagonal steel tube 110 and the drive screw 211, a simple geometric structure is used to achieve reliable axial limitation of the drive screw 211, flexible rotation, good multi-axis synchronization, and low cost.

[0044] In some embodiments, the cross-sectional outer contour of the steel tube 110 is circular, and the first end of each drive screw 211 abuts the outer circumference of the steel tube 110. In this embodiment, the circular steel tube 110 and the drive screw 211 are connected by bearings, achieving a comprehensive performance improvement of low friction, high precision, long life, and easy maintenance through standardized components.

[0045] Figure 4 The figure shows the contact between the nut to be disassembled and the claw clamp in the embodiment of the present application. Figure 5 Shown is a schematic diagram of the clamping connection between the nut to be disassembled and the clamping claw in the embodiment of the present application.

[0046] See also Figure 4 and Figure 5In some embodiments, the side of the clamping claw 320 that contacts the nut 10 to be disassembled is provided with an anti-slip structure 321. The anti-slip structure 321 can increase the friction coefficient between the clamping claw 320 and the nut 10 to be disassembled, improve contact reliability, and prevent the two from slipping or disengaging during the assembly and disassembly process.

[0047] See also Figure 4 and Figure 5 In some embodiments, the anti-slip structure 321 is a rubber pad. The rubber pad is anti-slip, durable, and has a buffering and shock-absorbing effect, further optimizing the anti-slip effect of the inner side of the clamping claw 320.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application.
