Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] like Figure 1~Figure 5 As shown, this embodiment proposes a bridge rubber expansion joint device, including a rubber plate 1 and a mounting plate 3, both ends of the rubber plate 1 are fixedly connected with an assembly plate 2, one side of the mounting plate 3 is fixedly connected with a support frame 4, one side of the support frame 4 is fixedly connected with an assembly frame 5, a slot 6 is provided inside the assembly frame 5, and the assembly plate 2 is plugged and connected inside the slot 6, both ends of the assembly frame 5 are provided with positioning components 7, the inner side of the support frame 4 is equipped with a guide component 8, and the guide component 8 is used to cooperate with the positioning component 7 to form a convenient and removable locking of the rubber plate 1;

[0025] The positioning assembly 7 includes a limit frame 9, a derivation rod 10, a positioning plate 11, a linkage frame 12 and a linkage rod 13. The top and bottom of both ends of the assembly frame 5 are fixedly connected to the limit frame 9, the middle part of the limit frame 9 is vertically slidably connected with the derivation rod 10, the bottom end of the derivation rod 10 is fixedly connected with the positioning plate 11, and the bottom end of the positioning plate 11 is connected with the assembly plate 2 by clamping, the top end of the derivation rod 10 is fixedly connected with the linkage frame 12, and the bottom of one end of the linkage frame 12 is fixedly connected with the linkage rod 13;

[0026] Here, the top and bottom ends of the assembly frame 5 are provided with avoidance holes, one end of the guide rod 10 close to the assembly frame 5 is fixedly connected with a locking shaft, the top and bottom ends of the assembly plate 2 are provided with matching lock holes, and the locking shaft passes through the avoidance holes and is connected with the matching lock holes by clamping. By using the setting of the locking holes and matching lock holes, the guide rod 10 can be stably connected with the assembly plate 2 to avoid uncontrollable movement of the assembly plate 2, thereby ensuring the assembly effect of the rubber plate 1;

[0027] Example 2

[0028] like Figure 1~Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes a guide component 8;

[0029] In this embodiment, the guide assembly 8 includes a central shaft 14, a threaded section 15, a displacement frame 16, a guide plate 17 and a guide slot 18. The inner side of the support frame 4 is laterally rotatably connected to the central shaft 14. Both ends of the outer side of the central shaft 14 are provided with threaded sections 15, and the threads of the two threaded sections 15 are opposite. The outer sides of the two threaded sections 15 are threadedly connected to the displacement frame 16. The top and bottom ends of the displacement frame 16 are obliquely fixedly connected to the guide slot 18, and the four linkage rods 13 are slidably connected to the inside of the four guide slots 18 respectively.

[0030] In summary, by rotating the central shaft 14 and cooperating with the setting of the two threaded sections 15 with opposite spiral directions, the two displacement frames 16 can move away from each other along the threaded sections 15. Since the guide slot 18 is inclined, the linkage rod 13 can follow the displacement of the displacement frame 16 and adjust vertically with the guide slot 18. Moreover, since the linkage rod 13 and the linkage frame 12 are supported by the derivation rod 10, the positioning plate 11 can be driven to be clamped into the assembly plate 2, thereby locking the position of the rubber plate 1.

[0031] In detail, a reinforcement seat is fixedly connected to the middle of the support frame 4, and the central shaft 14 is also rotatably connected to one end of the reinforcement seat. By setting the reinforcement seat, the central shaft 14 can be stably supported to prevent the central shaft 14 from shaking when rotating, thereby ensuring the displacement effect of the displacement frame 16;

[0032] Furthermore, one end of the central shaft 14 is fixedly connected to a force-bearing handle, and the outer side of the force-bearing handle is provided with anti-slip grooves;

[0033] Furthermore, a linear slide rod is fixedly connected to the inside of the support frame 4, a limiting hole is opened at one end of the displacement frame 16, and a clearance is matched between the limiting hole and the linear slide rod. By utilizing the setting of the linear slide rod, the displacement of the displacement frame 16 can be effectively guided to prevent the displacement frame 16 from rotating with the threaded segment 15.

[0034] A specific application of the above two embodiments is that firstly, two mounting plates 3 are installed in the expansion joint of the bridge, and then two assembly plates 2 are respectively inserted into the two slots 6 to form the initial assembly of the rubber sheet 1, and at the same time, the central shaft 14 is rotated, and the two threaded sections 15 with opposite spiral directions are arranged so that the two displacement frames 16 can move away from each other along the threaded sections 15. Since the guide slot 18 is arranged obliquely, the linkage rod 13 can follow the displacement of the displacement frame 16 and adjust vertically with the guide slot 18. Moreover, since the linkage rod 13 and the linkage frame 12 are supported by the derivation rod 10, the positioning plate 11 can be driven to be clamped into the assembly plate 2, so as to lock the position of the rubber sheet 1.

[0035] Subsequently, the central shaft 14 only needs to be rotated in the opposite direction to bring the two displacement frames 16 closer to each other, so that the positioning plate 11 can be moved out of the assembly plate 2 , and then the assembly plate 2 can be pulled out from the slot 6 to replace the rubber plate 1 .

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
