[0020] The lower end of the guide rod extends through the bottom surface of the U-shaped frame to the outside.

[0021] As a further optimization, to ensure the clamping strength of the rigid beam by adaptively adjusting the height of the clamping plate through the extension and contraction of the rigid spring when the rigid beam undergoes slight deformation, the adaptive adjusting clamping plate includes:

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] Please see Figure 1-6 This utility model provides a technical solution: a rigid beam fixing clamp, comprising:

[0052] Rigid beam 1, with fixing clamp bodies 2 clamped and fixed at both ends;

[0053] The fixing clamp body 2 includes:

[0054] U-shaped frame 21, which is sleeved at the end of rigid beam 1;

[0055] The top surface of the U-shaped frame 21 is equipped with a mounting base 22, and the bottom surface of the U-shaped frame 21 is equipped with a lifting clamping structure 23.

[0056] The end of the rigid beam 1 is clamped between the movable part of the lifting clamping structure 23 on the same side and the top surface of the inner cavity of the U-shaped frame 21;

[0057] The width of the U-shaped frame 21 is greater than the width of the rigid beam 1;

[0058] Reinforcing ribs 24 are uniformly fixedly assembled on the front and rear sides of the inner wall of the U-shaped frame 21 along the length direction.

[0059] The upper and lower ends of the reinforcing rib 24 abut against the top and bottom surfaces of the inner wall of the U-shaped frame 21, respectively, and the inner ends of the front and rear reinforcing ribs 24 abut against the same side of the outer wall of the movable part of the lifting clamping structure 23.

[0060] In this embodiment, both the U-shaped frame 21 and the rigid beam 1 are made of high-strength steel or alloy. During installation, the end of the rigid beam 1 is inserted between the reinforcing ribs 24 on the front and rear sides inside the U-shaped frame 21.

[0061] Furthermore, the reinforcing ribs 24 on the front and rear sides are tightly attached to the outer wall of the same side end of the rigid beam 1, which limits and shields the rigid beam 1 from moving back and forth due to vibration and thus prevents it from loosening. At the same time, the reinforcing ribs 24 are also used to improve the mechanical strength of the U-shaped frame 21, reduce the probability of deformation of the clamping body 2 under stress, and prevent the rigid beam 1 from loosening due to deformation of the clamping body 2.

[0062] More specifically, the movable part of the lifting clamping structure 23 can be raised and lowered by adjustment. Here, the lifting clamping structure 23 adopts a purely mechanical structure, which ensures the support strength while raising and lowering.

[0063] Understandably, multiple reinforcing ribs 24 are evenly arranged along the length of the inner wall of the U-shaped frame 21 on both the front and rear sides to distribute the pressure and ensure sufficient mechanical strength.

[0064] In some embodiments, the lifting clamping structure 23 includes:

[0065] Hand-tightened bolt 231 is screwed to the middle of the bottom surface of U-shaped frame 21;

[0066] The upper end of the hand-tightening bolt 231 extends into the U-shaped frame 21 and is rotatably connected to an adaptive adjustment clamp 232, the outer wall of which slides against the inner wall of the U-shaped frame 21.

[0067] The adaptive adjustment clamp 232 is the movable part of the lifting clamping structure 23.

[0068] Specifically in this embodiment, the outer wall of the nut of the hand-tightening bolt 231 is provided with anti-slip texture for easy gripping, and the main shell of the adaptive adjustment clamp 232 is made of high-strength steel or alloy.

[0069] Furthermore, the hand-tightening bolt 231 is tightened by rotating it clockwise. The upper end of the hand-tightening bolt 231 pushes the outer wall of the adaptive adjustment clamp 232 connected to the rotation to slide and rise against the inner wall of the U-shaped frame 21.

[0070] More specifically, the adaptive adjustment clamp 232 adjusts its height according to the slight deformation of the rigid beam 1. This adjustment is based on the elastic element installed inside it, which can maintain sufficient support strength while being stretched and contracted under force. In this embodiment, a rigid spring 2323 is used.

[0071] In some embodiments, guide rods 233 are vertically fixedly mounted on both the front and rear sides of the bottom of the adaptive adjustment clamp 232;

[0072] The lower end of the guide rod 233 extends through the bottom surface of the U-shaped frame 21 to the outside.

[0073] In some embodiments, the adaptive adjustment clamp 232 includes:

[0074] Mounting plate 2321, the upper surface of which is provided with mounting groove;

[0075] A piston plate 2322 is slidably inserted into the upper end of the inner wall of the mounting groove;

[0076] Rigid springs 2323 are uniformly fixed between the bottom surface of the piston plate 2322 and the bottom surface of the inner cavity of the mounting groove.

[0077] Specifically in this embodiment, the piston plate 2322 slides inside the mounting groove and is supported by evenly distributed rigid springs 2323. The upper end of the piston plate 2322 extends out of the mounting groove and abuts against the bottom surface of the rigid beam 1. At this time, the rigid springs 2323 are in a compressed state and there is still room for further compression.

[0078] Furthermore, slight deformation of the rigid beam 1 can cause it to squeeze or detach from the piston plate 2322. The rigid spring 2323 then drives the piston plate 2322 to remain in contact with the bottom surface of the rigid beam 1, thus achieving adaptive adjustment when the rigid beam 1 undergoes slight deformation.

[0079] It is understandable that there are multiple rigid springs 2323 evenly distributed together to support the piston plate 2322 and ensure the stability of the support.

[0080] In some embodiments, a rubber pad 2324 is attached to the top surface of the piston plate 2322, which abuts against the bottom surface of the end of the rigid beam 1, increasing the friction between the lifting clamping structure 23 and the contact surface of the rigid beam 1, and improving installation stability.

[0081] In some embodiments, the reinforcing rib 24 includes:

[0082] A rectangular plate 241 is longitudinally inserted between the top and bottom surfaces of the inner wall of the U-shaped frame 21;

[0083] The lower end of the U-shaped frame 21 corresponds to the rectangular plate 241 through which a fixing bolt 242 passes, and its upper end is screwed to the bottom surface of the rectangular plate 241.

[0084] Specifically in this embodiment, the rectangular plate 241 fixed between the top and bottom surfaces of the inner wall of the U-shaped frame 21 plays a supporting role and improves the mechanical strength of the U-shaped frame 21;

[0085] Furthermore, the rectangular plate 241 is fixed by fixing bolts 242, which facilitates installation and disassembly;

[0086] More specifically, depending on the material of the rectangular plate 241, the spacing and number of the fixed rectangular plates 241 are adjusted. When the rectangular plate 241 is made of ordinary steel, the spacing of the rectangular plates 241 is reduced and the number of rectangular plates 241 is increased; when the rectangular plate 241 is made of high-strength steel or alloy, the spacing of the rectangular plates 241 is increased and the number of rectangular plates 241 is reduced to ensure sufficient support strength.

[0087] In some embodiments, the mounting base 22 includes:

[0088] Vertical plate 221 is integrally formed on the upper end of U-shaped frame 21;

[0089] The upper part of the outer wall of the vertical plate 221 has a horizontal plate 222 integrally formed.

[0090] Specifically in this embodiment, the horizontal plate 222 at the upper end of the vertical plate 221 is welded to the water-cooled wall structure of the boiler system as an ear plate for fixing the whole device.

[0091] Furthermore, the number of vertical plates 221 and matching horizontal plates 222 can be multiple, thereby increasing the strength of the welding fixation.

[0092] In some embodiments, a snap-fit ​​positioning structure 3 is fitted between the top surface of the end of the rigid beam 1 and the top surface of the inner cavity of the U-shaped frame 21, which facilitates snap-fit ​​positioning of the left and right installation positions of the rigid beam 1 and ensures that the installation position of the rigid beam 1 is accurate.

[0093] In some embodiments, the locking and positioning structure 3 includes:

[0094] The snap-fit ​​groove 31 is evenly opened along the length direction on the top surface of the end of the rigid beam 1;

[0095] A snap-fit ​​block 32 is fixedly assembled on the top surface of the inner cavity of the U-shaped frame 21 corresponding to the snap-fit ​​groove 31, and the snap-fit ​​block 32 is inserted into the corresponding snap-fit ​​groove 31.

[0096] Specifically in this embodiment, before use, it is necessary to lower the height of the adaptive adjustment clamp 232, insert the end of the rigid beam 1 between the top surface of the U-shaped frame 21 and the adaptive adjustment clamp 232, and ensure that the end face of the rigid beam 1 is in contact with the inner wall side of the U-shaped frame 21. Move the rigid beam 1 up so that the snap-fit ​​block 32 is inserted into the corresponding snap-fit ​​groove 31 to complete the snap-fit. Then, raise the adaptive adjustment clamp 232 to abut against the bottom surface of the rigid beam 1 for clamping and fixing.

[0097] Furthermore, multiple snap-fit ​​blocks 32 and snap-fit ​​grooves 31 cooperate with each other to snap-fit ​​and position the rigid beam 1 at the left and right installation positions, ensuring the accurate installation position of the rigid beam 1, while avoiding loosening caused by the rigid beam 1 moving left and right due to vibration.

[0098] In some embodiments, the outer wall of the U-shaped frame 21 is provided with a corrosion-resistant coating 4 to improve the corrosion resistance of the U-shaped frame 21. The corrosion-resistant coating 4 can be a zinc-plated coating or a plastic coating. In this embodiment, the corrosion-resistant coating 4 is a plastic coating formed by powder coating.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
