Description

Technical Field

[0001] This utility model relates to the field of bolt installation technology, and in particular to a bolt installation device for steel structure connection specimens. Background Technology

[0002] To test the performance of steel structure building module connections, it is usually necessary to fabricate steel structure connection specimens. By conducting relevant performance tests on the specimens, parameters such as the strength performance of the simulated steel structure building module connections can be detected.

[0003] Among them, the steel structure connection test specimen is usually composed of multiple steel structures used for testing and simulation. The connection between the steel structures is mostly done by bolts. When installing the bolts, a wrench is usually used to tighten them, which allows the bolts to rotate better and connect with the nuts. This can achieve a tightness effect between the steel structure connection test specimens, so that the entire steel structure system forms a stable load-bearing whole.

[0004] Electric wrenches are currently an important tool for bolt installation. However, when installing bolts on steel structure connection specimens, most of these specimens lack external structures suitable for bolt fixing due to considerations of structural strength and spatial layout. Bolts are often suspended or unstable during installation. Electric wrenches, however, only have the function of unidirectional tightening of nuts or screws. During tightening, they cannot directly limit and fix the suspended nuts or screws, requiring workers to use one hand to precisely clamp and fix the nuts or screws with auxiliary tools to ensure stability during tightening. This forces workers to use only one hand to support the electric wrench, making it difficult to maintain its verticality and balance during use. Uneven force can easily cause the nuts or screws to slip or become misaligned, further affecting the bolt installation effect. Therefore, we provide a bolt installation device for steel structure connection specimens. Utility Model Content

[0005] This utility model provides a bolt installation device for steel structure connection specimens to solve the technical problems existing in the background art.

[0006] The purpose and effect of this utility model for a bolt installation device for steel structure connection specimens are achieved by the following specific technical means: A bolt installation device for steel structure connection specimens includes an electric wrench. One side of the electric wrench is provided with a positioning component for limiting and stabilizing nuts or screws. The positioning component includes a retaining frame installed on the outer surface of the electric wrench. A sliding frame is engaged with the inner wall of the retaining frame. A sliding plate is slidably connected to the inner wall of the sliding frame. A support plate is fixedly connected to the other end of the sliding plate. A through groove is opened on the front side of the support plate. A set of clamping plates is provided inside the through groove.

[0007] The positioning component also includes an adjustment structure disposed on one side of the support plate for adjusting the spacing between the clamping plates and stabilizing the clamping plates.

[0008] Preferably, the adjustment structure of the positioning component includes a positive and negative threaded rod rotatably connected to a set of clamps. One end of the positive and negative threaded rod is rotatably connected to a support block on the outer surface of the positive and negative threaded rod, and the other ends of the two support blocks are respectively connected to the left and right sides of the support plate.

[0009] Preferably, a hexagonal cap is fixedly connected to the other end of the positive and negative threaded rod.

[0010] Preferably, a first fastening screw is threaded onto one side of the card frame, and the other end of the first fastening screw contacts the outer surface of the slide frame.

[0011] Preferably, the upper surface of the slide frame is threaded with a second fastening screw, and the other end of the second fastening screw is in contact with the upper surface of the slide plate.

[0012] Preferably, guide frames are fixedly connected to both the left and right sides of the sliding frame, and a reinforcing plate is slidably connected to the inner wall of each guide frame. The rear ends of the two reinforcing plates are respectively connected to the left and right sides of the support plate.

[0013] Preferably, a diagonal brace is fixedly connected to the upper surface of the skateboard, and the top of the diagonal brace is connected to the front of the support plate.

[0014] Preferably, a limiting groove is formed inside the slide plate, and a limiting rod is slidably connected to the inner wall of the limiting groove. The front end of the limiting rod is connected to the inner wall of the slide frame.

[0015] Beneficial effects:

[0016] By using the positioning component in conjunction with the electric wrench, the electric wrench can replace manual hand-holding of auxiliary tools to limit and fix nuts or screws that are suspended in the air. Operators can then use both hands to firmly grip the electric wrench to work, ensuring that the electric wrench remains vertical and balanced during use. This effectively prevents nuts or screws from slipping or being twisted due to uneven force, further ensuring the bolt installation effect.

[0017] The first fastening screw can hold the slide frame inserted into the card frame, thus ensuring that the slide frame is firmly inserted into the card frame. The second fastening screw can reinforce the slide plate to prevent it from sliding automatically, thereby preventing the clamp plate from separating from the nut or screw.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] As attached Figure 1 Appendix Figure 2 With appendix Figure 3 As shown: A bolt installation device for a steel structure connection specimen includes an electric wrench 1, model SGDD-230. One side of the electric wrench 1 is provided with a positioning component 2 for limiting and stabilizing nuts or screws. The positioning component 2 includes a retaining frame 201 installed on the outer surface of the electric wrench 1. A sliding frame 202 is engaged with the inner wall of the retaining frame 201. A sliding plate 203 is slidably connected to the inner wall of the sliding frame 202. A support plate 204 is fixedly connected to the other end of the sliding plate 203. A through groove 205 is opened on the front of the support plate 204. A set of clamping plates 206 is provided inside the through groove 205. After the sliding frame 202 is engaged with the retaining frame 201, the sliding frame 202 and the sliding plate 203 will support the support plate 204. Then, the sliding plate 203 can be pulled to move the support plate 204 until the clamping plate 206 is outside the screw or nut to be limited and stabilized.

[0026] As attached Figure 1 Appendix Figure 2 With appendix Figure 4As shown: A first fastening screw 210 is threaded onto one side of the retaining frame 201. The other end of the first fastening screw 210 contacts the outer surface of the sliding frame 202. By tightening the first fastening screw 210, its end can be pressed against the outer surface of the sliding frame 202, thereby improving the stability of the sliding frame 202 inside the retaining frame 201. A second fastening screw 211 is threaded onto the upper surface of the sliding frame 202. The other end of the second fastening screw 211 contacts the upper surface of the slide plate 203. The second fastening screw 211 can be used to press its end against the outer surface of the slide plate 202. The outer surface of the slide plate 203 allows the slide plate 203 to remain firmly inside the slide frame 202, thereby preventing the slide plate 203 from moving on its own and ensuring that the clamping plate 206 is outside the screw or nut that needs to be limited and stabilized. The slide plate 203 has a limit groove 215 inside, and the inner wall of the limit groove 215 is slidably connected to a limit rod 216. The front end of the limit rod 216 is connected to the inner wall of the slide frame 202. By using the cooperation between the limit rod 216 and the limit groove 215, the movement of the slide plate 203 can be limited, preventing the slide plate 203 from detaching from the slide frame 202.

[0027] As attached Figure 2 Appendix Figure 3 With appendix Figure 4 As shown: The positioning component 2 also includes an adjustment structure disposed on one side of the support plate 204 for adjusting the distance between the clamping plates 206 and stabilizing the clamping plates 206. The adjustment structure of the positioning component 2 includes a positive and negative threaded rod 207 rotatably connected to a set of clamping plates 206. One end of the positive and negative threaded rod 207 and the outer surface of the positive and negative threaded rod 207 are rotatably connected to the support block 208. The other ends of the two support blocks 208 are respectively connected to the left and right sides of the support plate 204. By rotating the positive and negative threaded rod 207, the two clamping plates 206 can be adjusted to move closer to each other, and the clamping plates 206 will form a stabilizing force on the screw or nut, thereby replacing manual operation. The auxiliary tool is used to limit and fix the nut or screw in a suspended state. The operator can then use both hands to firmly grip the electric wrench 1 to work, so that the electric wrench 1 remains vertical and balanced during use, effectively preventing the nut or screw from slipping or twisting due to uneven force, and further ensuring the bolt installation effect. At the same time, the distance between the two clamps 206 can be adjusted to make it suitable for screws or nuts of different sizes. The other end of the positive and negative thread rod 207 is fixedly connected to a hexagonal cap 209. The operator can use the hexagonal wrench to insert into the hexagonal cap 209, so as to easily rotate the positive and negative thread rod 207.

[0028] As attached Figure 2As shown: Guide frames 212 are fixedly connected to both the left and right sides of the sliding frame 202. A reinforcing plate 213 is slidably connected to the inner wall of each guide frame 212. The rear ends of the two reinforcing plates 213 are respectively connected to the left and right sides of the support plate 204. By utilizing the cooperation of the guide frames 212 and the reinforcing plates 213, the firmness of the connection between the sliding plate 203 and the support plate 204 can be enhanced. The torque force applied by the support plate 204 to the sliding plate 203 can be dispersed, thereby preventing the support plate 204 and the sliding plate 203 from bending and breaking. A diagonal plate 214 is fixedly connected to the upper surface of the sliding plate 203. The top of the diagonal plate 214 is connected to the front of the support plate 204. When the support plate 204 is subjected to vertical pressure or horizontal thrust, the diagonal plate 214 can convert these external forces into its own axial tension and pressure, giving full play to the stability advantage of the triangular structure, enhancing the overall rigidity of the support plate 204, and effectively reducing its deformation under stress.

[0029] Working principle: When in use, slide frame 202 is inserted into clamp frame 201, then electric wrench 1 is inserted into the outside of screw or nut. Next, slide plate 203 is pushed to move until support plate 204 moves clamp plate 206 to the outside of screw or nut. Then, using auxiliary tools, hexagonal nut 209 is rotated, and the forward and reverse thread rod 207 will rotate on clamp plate 206. The two clamp plates 206 will gradually approach each other to form a stable clamping of screw or nut, which can replace manual clamping and limiting of nut or screw using auxiliary tools. Then, the operator can use both hands to firmly hold electric wrench 1 to work, so that electric wrench 1 remains vertical and balanced during use, effectively avoiding slippage or misalignment of nut or screw due to uneven force, further ensuring the bolt installation effect. When installing bolts in narrow spaces, slide frame 202 can be removed from clamp frame 201 to avoid affecting the bolt installation work.
