[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1,

[0034] like Figure 1 As shown, a steel structure bridge reinforcement device comprises a cross beam 1, a base 2 and a beam reinforcement seat 3. The base 2 is fixedly mounted on the cross beam 1, and the beam reinforcement seat 3 is slidably mounted on the inner surface of the base 2. The opposite outer surfaces of the beam reinforcement seat 3 are respectively provided with fixing grooves 31, and the inner surfaces of the fixing grooves 31 are provided with clamping holes 32 (refer to Figure 5 ); the inner surface of the base 2 is provided with a mounting block 21, and the mounting block 21 is slidably mounted inside the fixing groove 31.

[0035] An installation groove 22 is provided inside the installation block 21, and a fixing device 4 is installed in the installation groove 22. The clamping block 45 of the fixing device 4 is slidably installed in the clamping hole 32. Specifically, a mounting block 21 is provided on each of the two inner surfaces of the base 2, and the mounting block 21 and the base 2 are fixedly connected by welding or bolts.

[0036] The beam reinforcement seat 3 is a square box with openings at the upper end and the side ends. The beam reinforcement seat 3 is slidably installed on the inner surface of the base 2. The base 2 and the beam reinforcement seat 3 are fixedly connected by a fixing device 4 arranged in the installation groove 22 and slidingly installed in the clamping hole 32. When the fixing device 4 is moved out of the clamping hole 32, the base 2 and the beam reinforcement seat 3 are separated, thereby realizing quick connection and separation of the base 2 and the beam reinforcement seat 3. The structure is simple, the operation is convenient, the installation time is saved, and the fixing efficiency and disassembly efficiency are improved.

[0037] refer to Figure 6 The fixing device 4 includes a turntable 44, a block 45 and a pull rod 46. The turntable 44 is rotatably installed in the installation groove 22. One end of the pull rod 46 is fixedly connected to the block 45, and the other end is slidably connected to the groove on the side surface of the turntable 44.

[0038] Specifically, in this embodiment, the disk 42 is manually rotated to drive the rotating rod 43 to drive the turntable 44 to rotate, and the rotation of the turntable 44 drives the pull rod 46 to slide along the circumferential direction of the turntable 44. Since the outer side of the turntable 44 is a diamond or elliptical shape, the turntable 44 then pulls the block 45 to make the block 45 slide from the hole 32 into the slide groove 222, thereby realizing that the fixing device 4 is moved to the slide groove 222 and is no longer stuck in the hole 32, thereby facilitating the removal of the beam reinforcement seat 3 from the fixing device 4.

[0039] In the above embodiment, another optional implementation is that the fixing device 4 includes a rotating disk 44, a clamping block 45 and a pull rod 46, the rotating disk 44 is rotatably installed in the installation groove 22, and the two ends of the pull rod 46 are respectively rotatably connected with the clamping block 45 and the rotating disk 44. Specifically, in this embodiment, the rotating disk 42 is manually rotated to drive the rotating rod 43 to drive the rotating disk 44 to rotate, and the rotating disk 44 is rotated to drive the pull rod 46 to rotate along the circumferential direction of the rotating disk 44, thereby pulling the clamping block 45 so that the clamping block 45 slides from the clamping hole 32 into the slide groove 222, thereby realizing that the fixing device 4 is moved to the slide groove 222, and no longer clamps the clamping hole 32, thereby facilitating the beam reinforcement seat 3 to be taken out of the fixing device 4.

[0040] In combination with the embodiment of the present invention, the fixing device 4 further includes a clamping spring 41 , which is sleeved on the outside of the pull rod 46 , and two ends of the clamping spring 41 respectively contact the clamping block 45 and the inner surface of the installation groove 22 .

[0041] Specifically, the retaining spring 41 plays a resetting role, and the rotation of the turntable 44 drives the clamping block 45 to move toward the rotating rod 43, at which time the retaining spring 41 is compressed. The retaining spring 41 has elastic energy. When the rotating rod 43 is released, the clamping block 45 is reset under the elastic force of the retaining spring 41, and then the clamping block 45 is clamped into the clamping hole 32 to achieve a fixed connection between the base 2 and the beam reinforcement seat 3. The thickness of the clamping block 45 is greater than the depth of the clamping hole 32, that is, the clamping block 45 is located in the slide groove 222 and the clamping hole 32 at the same time or is only located in the slide groove 222.

[0042] refer to Figure 2 The fixing device 4 further includes a disc 42, which is located outside the base 2; a rotating rod 43 is arranged at the center of the rotating disc 44, and one end of the rotating rod 43 passes through the mounting block 21 and the base 2 and is fixedly connected to the disc 42. Specifically, the disc 42 is exposed outside the base 2, which is convenient for the staff to operate.

[0043] Working principle: when the beam reinforcement seat 3 needs to be taken out from the base 2, the disk 42 is manually rotated to drive the rotating rod 43 to drive the turntable 44 to rotate, and the turntable 44 rotates to drive the pull rod 46 to slide along the circumferential direction of the turntable 44 (refer to Figure 7 ), since the outer side of the turntable 44 is rhombus or elliptical, the turntable 44 then pulls the block 45 to make the block 45 slide from the clamping hole 32 into the slide groove 222, thereby realizing that the fixing device 4 moves into the slide groove 222 and is no longer stuck in the clamping hole 32, thereby facilitating the removal of the beam reinforcement seat 3 from the fixing device 4; the mounting groove 22 includes a circular groove 221 and a slide groove 222, and the circular groove 221 and the slide groove 222 are connected; the turntable 44 is rotatably installed in the circular groove 221, the retaining spring 41 is installed in the slide groove 222, and the block 45 is slidably installed in the slide groove 222 and the clamping hole 32, one end of the retaining spring 4 abuts against the block 45, and the other end abuts against the slide groove 222.

[0044] When it is necessary to install the beam reinforcement seat 3 in the fixing device 4, the disk 42 is manually rotated to drive the rotating rod 43 to drive the rotating disk 44 to rotate, and the rotation of the rotating disk 44 drives the pull rod 46 to slide along the circumferential direction of the rotating disk 44. Since the outer side of the rotating disk 44 is a diamond or elliptical shape, the rotating disk 44 further pulls the clamping block 45 to make the clamping block 45 slide from the clamping hole 32 into the sliding groove 222, thereby realizing that the fixing device 4 moves into the sliding groove 222 and no longer gets stuck in the clamping hole 32. This process compresses the clamping spring 41, thereby making the clamping spring 41 have elastic properties, and then the beam reinforcement seat 3 is installed in the fixing device 4, and the disk 42 is released. Under the elastic force of the clamping spring 41, the clamping block 45 slides from the sliding groove 222 into the clamping hole 32, thereby realizing that the beam reinforcement seat 3 is stuck, and the beam reinforcement seat 3 and the fixing device 4 are fixed. The structure is simple, the operation is convenient, the installation time is saved, and the fixing efficiency is improved.

[0045] refer to Figure 3 The structural bridge reinforcement device further comprises a cross beam 1 and a vertical beam 11, the base 2 is fixedly connected to the cross beam 1, and the cross beam 1 is fixedly connected to the vertical beam 11. Specifically, the present invention adjusts different positions of the cross beam 1 by fixing the cross beam 1 to the vertical beam 11 at different positions.

[0046] In the above embodiment, another optional implementation is that the structural bridge reinforcement device also includes a U-shaped reinforcement plate 14, which is installed at the end of the horizontal beam 1 away from the vertical beam 11, and the vertical beam 11, the horizontal beam 1 and the U-shaped reinforcement plate 14 are connected by a through screw 12.

[0047] Specifically, Figure 1 As shown, this scheme includes two vertical beams 11 with the same structure and two U-shaped reinforcement plates 14 with the same structure. The vertical beams 11 and the U-shaped reinforcement plates 14 are respectively provided with symmetrically arranged through holes 1 and 2, and the cross beam 1 is provided with symmetrically arranged screw holes 13; four through screws 12 and locking nuts 10 are provided, and the four through screws 12 pass through the corresponding through holes 1 and 2 and fix the cross beam 1 and the vertical beam 11 through the screw holes 13. Four locking nuts 10 are provided on one side of the corresponding U-shaped reinforcement plates 14 and are threadedly matched with the through screws 12 to fix the U-shaped reinforcement plates 14 and the cross beam 1. The female locking nuts 10 are tightened one by one to connect the cross beam 1, the vertical beam 11 and the U-shaped reinforcement plates 14, thereby improving the connection strength.

[0048] Embodiment 2,

[0049] This embodiment adds the following structure on the basis of Embodiment 1:

[0050] refer to Figure 4 A plurality of circumferentially arrayed positioning holes 5 are provided on the rotating rod 43 , and a limiting device is slidably installed in the slide groove 222 on the surface of the base 2 , and the limiting device is slidably installed in the positioning hole 5 .

[0051] The limiting device includes a positioning block 6, a positioning rod 7 and a push rod 8 connected in sequence. The push rod 8 is slidably installed in a groove on the surface of the base 2, and one end of the push rod 8 away from the positioning rod 7 is located on the outside of the surface of the base 2. The push rod 8 and the disk 42 are located on the same side of the base 2. One end of the push rod 8 is connected to the positioning block 6 through the positioning rod 7, and the positioning block 6 is slidably installed in the positioning hole 5.

[0052] Specifically, Figure 2 As shown, a square groove is provided on the symmetrical surface of the base 2, and a portion of the push rod 8 is slidably installed in the square groove.

[0053] In the implementation of the present invention, a positioning spring 9 is sleeved on the positioning rod 7 , one end of the positioning spring 9 abuts against the positioning block 6 , and the other end abuts against the base 2 .

[0054] The positioning spring 9 plays a resetting role. When the push rod 8 is manually pulled to move the push rod 8 away from the disk 42, the positioning spring 9 is compressed, and the positioning block 6 leaves the positioning hole 5 to facilitate the rotation of the disk 42. When the push rod 8 is released, under the elastic force of the positioning spring 9, the positioning block 6 enters the positioning hole 5 and then jams the rotating rod 43, thereby fixing the rotating rod 43.

[0055] like Figure 2 As shown, two square grooves are provided on the base 2, and parts of the push rod 8 are slidably connected inside the square grooves.

[0056] Two positioning grooves are provided on the base 2 , and a portion of the positioning block 6 is slidably connected inside the positioning grooves. A positioning spring 9 is fixedly connected between the positioning block 6 and the inner wall of the positioning groove.

[0057] The specific implementation principle of this embodiment is as follows: pushing the push rod 8 drives the positioning rod 7 to move away from the rotating rod 43, and the positioning rod 7 drives the positioning block 6 to disengage from the positioning hole 5. Then the disc 42 can be manually rotated, thereby driving the rotating rod 43 to drive the turntable 44 to rotate. The rotation of the turntable 44 drives the pull rod 46 to slide along the circumferential direction of the turntable 44. Since the outer side of the turntable 44 is a diamond or elliptical shape, the turntable 44 then pulls the clamping block 45 to make the clamping block 45 slide from the clamping hole 32 into the slide groove 222, thereby realizing that the fixing device 4 is moved to the slide groove 222 and is no longer stuck in the clamping hole 32, thereby facilitating the removal of the beam reinforcement seat 3 from the fixing device 4.

[0058] To achieve installation and disassembly, loosen the positioning rod 7, and the positioning spring 9 drives the positioning block 6 to reset and snap into the positioning hole 5, so that the rotating rod 43 is fixed to ensure the stability of positioning. At the same time, the fixing of the card block 45 can be achieved through the limitation of the positioning block 6, and it is more convenient to install the beam reinforcement seat 3, without having to manually hold the rotating rod 43 or the push rod 8 all the time.
