Description

Technical Field

[0001] The present invention relates to the technical field of metal shaft supports, and specifically to a shaft support mechanism for steel structures. Background Art

[0002] The shaft support mechanism in steel structures is a structure for supporting metal shafts and is often used in the construction industry.

[0003] After retrieval, the Chinese utility model patent with the authorization announcement "CN202023251U" discloses a "shaft support mechanism for steel structures". This application not only strengthens the support performance of the shaft support during actual use by connecting with inclined struts and forming connection positions, but also makes the shaft support have a certain degree of adjustability, achieving an extension of the service life and practical scope of the shaft support in steel structures.

[0004] However, during actual use of the above device, no protective device is provided for the metal shaft placed inside the shaft support. This causes the actual service life of the metal shaft to decrease during actual use. Therefore, the applicant proposes a new device to solve the above existing problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a shaft support mechanism for steel structures to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A shaft support mechanism for steel structures, comprising:

[0007] An assembly round box;

[0008] A cover body, which is inserted and installed at the opening on the top of the assembly round box and is used to seal the assembly round box;

[0009] An assembly cavity, which is a self-formed area inside the assembly round box, and a transmission gear is rotatably connected at the center point inside it;

[0010] A sliding notch, which is opened at both ends outside the assembly round box and is connected to the assembly cavity;

[0011] A positioning mechanism, of which there are two. The two positioning mechanisms are inserted and installed outside the assembly round box by means of the corresponding sliding notches;

[0012] Carrying arms are respectively fixed on both sides outside the assembly round box. Four arc-shaped guiding grooves are opened on the top of the cover body. The four arc-shaped guiding grooves are arranged equiangularly and evenly with the center of the cover body as the reference point. There must be an arc-shaped guiding groove between two adjacent carrying arms and the positioning mechanism;

[0013] The positioning mechanism includes:

[0014] A sliding block, which is adapted to the sliding notch, and a rack is fixed at one end thereof facing the assembly cavity. The racks on the two positioning mechanisms are offset from each other and respectively mesh with the two outer sides of the transmission gear;

[0015] The other end of the sliding block is fixed with a bolt seat for placing a metal shaft. A rotatable guiding member is installed between the sliding block and the adjacent carrying arm, and the input end of the protection member is adapted to the arc-shaped guiding groove;

[0016] When the two sliding blocks move simultaneously towards the center position of the assembly round box, the input end of the protection member turns by means of the arc-shaped guiding groove, and the output end of the protection member is moved to the outer position of the center line of the two bolt seats.

[0017] Further, the guiding member includes:

[0018] Eight rotating columns, which are evenly fixed on the two outer sides of the two sliding blocks and the two outer sides of the two carrying arms;

[0019] Mounted on different components, and connecting arms are respectively installed between the two closest rotating columns. A folding arm with a bendable center position is hinged between the two connecting arms. A connecting shaft is installed at the top of the folding arm. The top end of the outer part of the connecting shaft is rotatably connected with a connecting sleeve. One end of the connecting sleeve is fixed with a guiding bent rod, and a contact guard plate is fixed at the top of the connecting sleeve;

[0020] Wherein the contact guard plate is the output end of the guiding member, and the guiding bent rod is the input end of the guiding member.

[0021] Further, the connecting arm is fixedly connected to the rotating column on the sliding block, and the connecting arm is hinged to the rotating column on the carrying arm.

[0022] Further, the contact guard plate is a deformable metal material plate, and a power supply line for connecting a power source in series is fixed on the periphery of the contact guard plate.

[0023] Further, a carrying seat is fixed at the bottom of the assembly round box, and through holes for installing connecting pieces are respectively opened around the top of the carrying seat.

[0024] Further, the connecting piece is any one of a fastening bolt, a reinforcing nail and an expansion bolt.

[0025] Further, the wiring mode of the power supply line on the contact guard plate can be divided into the following two cases under different conditions:

[0026] First, when the metal shaft between the two bolt seats is exposed to the outside, based on both sides of the mounting seat, the power supply wires on the two contact guards on one side contact the positive pole of the power supply, and the power supply wires on the two contact guards on the other side contact the negative pole of the power supply;

[0027] Second, when the metal shaft between the two bolt seats is not exposed to the outside, based on both ends of the mounting seat, the power supply wires on the two contact guards at one end contact the positive pole of the power supply, and the power supply wires on the two contact guards at the other end contact the negative pole of the power supply.

[0028] Furthermore, a detachable arc cover is installed on the top of the bolt seat, and a buffer pad is fixed at the inner arc surface of the arc cover.

[0029] Furthermore, communication ports are respectively opened at both ends of the top of the arc cover, and a locking bolt adapted to the bolt seat is installed on the arc cover by means of the communication ports.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] In the shaft support mechanism of the steel structure, by installing a transmission gear inside the assembly round box, installing two sliding blocks and two mounting arms outside the assembly round box respectively, and installing a rack adapted to the transmission gear on the sliding block, when the two sliding blocks move simultaneously towards the center position of the assembly round box, the protective components installed between the sliding block and the mounting arm turn by means of the arc-shaped guiding groove on the top cover of the assembly round box, and the output end of the protective component moves to the periphery of the center line of the two bolt seats to complete the protection and clamping limit of the outside of the metal shaft placed on the bolt seat, which improves the stability of the metal shaft placed on the bolt seat to a certain extent;

[0032] At the same time, the contact guard is made of a deformable metal material plate, and the power supply wires for connecting the power supply are installed outside the metal material plate. When the device is actually used, the outer surface of the metal shaft can form premature oxides in a conductive form, slowing down the corrosion of the inside of the metal shaft by rainwater, and extending the service life of the metal shaft to a certain extent.

The racks 207 on the two positioning mechanisms 2 are mutually offset and are respectively engaged with the two sides of the outside of the transmission gear 9. The other end of the sliding block 209 is fixed with a bolt seat 211 for placing the metal shaft 3. A rotatable guiding member is installed between the sliding block 209 and the adjacent carrying arm 6. The input end of the protection member is adapted to the arc-shaped guiding groove 5.
