[0038] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0039] like Figure 1~Figure 4 As shown, this embodiment proposes a linkage opening and closing machine, including a barrel 1, a gate body 2, a clamping block 3 and a linkage assembly. Mounting seats are provided on both sides of the barrel 1, and the bottom end of the barrel 1 is communicated with the outside world, so that the gate body 2 can be easily moved in and out of the barrel 1. The gate body 2 is lifted and lowered in the barrel 1 by a lifting seat. A plurality of clamping blocks 3 are provided, and the plurality of clamping blocks 3 are respectively provided on both sides of the gate body 2. The linkage assembly is provided between the plurality of clamping blocks 3, and a non-slip pad 17 is fixedly connected to one side of the plurality of clamping blocks 3 close to each other, so as to stably clamp the gate body 2.

[0040] like Figure 1~Figure 4 As shown, the linkage assembly includes a double-headed electric cylinder 4, a linkage frame 5, a pushing column 6, a pushing plate 7 and a pushing strip 8. The double-headed electric cylinder 4 is installed on one side of the barrel 1, and a driven plate 16 is fixedly connected to the outer wall of the barrel 1. The double-headed electric cylinder 4 is installed on the top of the driven plate 16, which is convenient for stably supporting and installing the double-headed electric cylinder 4. There are two linkage frames 5, and the two linkage frames 5 are fixedly connected to the output end of the double-headed electric cylinder 4. The pushing column 6 is fixedly connected to each linkage frame 5, and the pushing column 6 is slidably connected to the barrel 1. The pushing plate 7 is fixedly connected to one side of each pushing column 6. There are multiple pushing strips 8, and multiple pushing strips 8 are fixedly connected to the pushing plate 7, and a pushing rod is fixedly connected between the pushing strip 8 and the adjacent clamping block 3.

[0041] By pushing the two linkage frames 5 simultaneously through the double-head electric cylinder 4, the two linkage frames 5 can simultaneously push the two push plates 7 through the two push columns 6. Through the movement of the push plates 7, the multiple push bars 8 can push the clamping block 3 through the multiple push rods, so that the clamping block 3 can clamp the gate body 2 through the anti-slip pad 17.

[0042] like Figure 1~Figure 4As shown, the lifting seat includes a fixed frame 9, an electric cylinder 10 and a sliding block 11. The fixed frame 9 is fixedly connected to the top of the barrel 1. The electric cylinder 10 is provided in two numbers. The two electric cylinders 10 are symmetrically installed in the fixed frame 9, and the output end of the electric cylinder 10 passes through the side wall of the fixed frame 9 and is fixedly connected to the gate body 2. The sliding block 11 is provided in two numbers. The two sliding blocks 11 are symmetrically connected to both sides of the gate body 2. A sliding groove for the sliding block 11 to slide is provided on the inner side wall of the barrel 1. Through the cooperation of the sliding block 11 and the sliding groove, the stability of the gate moving in the barrel 1 is increased.

[0043] By starting the two electric cylinders 10 , the two electric cylinders 10 can push the gate body 2 , so as to adjust the position of the gate body 2 in the barrel 1 , thereby facilitating the opening and closing of the gate body 2 in the barrel 1 .

[0044] like Figure 1~Figure 4 As shown, the mounting seat includes a mounting plate 12, a mounting column 13 and a mounting frame 14. The mounting plates 12 are provided in two, and the two mounting plates 12 are fixedly connected to the outer wall of the barrel 1. The mounting column 13 is fixedly connected between the two mounting plates 12. The mounting frame 14 is rotatably mounted on the mounting column 13, and a mounting hole is opened on the mounting frame 14.

[0045] The two mounting plates 12 facilitate stable connection of the mounting column 13, and the mounting angle of the mounting frame 14 can be adjusted by rotating the mounting frame 14 on the mounting column 13. At the same time, the cooperation between the mounting frame 14 and the mounting hole facilitates stable installation of the barrel 1 on the dam body.

[0047] The through-hole facilitates the push column 6 to stably move on the barrel 1. At the same time, the movement of the push column 6 in the through-hole can be limited by the cooperation of the limit block 15 and the limit groove, so that the push column 6 can stably move the push plate 7.

[0048] In this embodiment, when the gate body 2 needs to be moved, the gate body 2 is first pulled by two electric cylinders 10 to pull the gate body 2 back into the barrel 1, and the two linkage frames 5 are simultaneously pushed by the double-headed electric cylinder 4, so that the two linkage frames 5 simultaneously push the two push plates 7 through the two push columns 6, so that the two push plates 7 simultaneously push the two clamping blocks 3 through the multiple push bars 8 and the multiple push rods. Through the relative movement of the two clamping blocks 3, the gate body 2 can be stably clamped in the barrel 1, thereby facilitating the increase of the stability of the barrel 1 in moving the gate body 2;

[0049] When the barrel 1 moves to a suitable position, the mounting frame 14 is rotated on the mounting column 13. When the mounting frame 14 is rotated to a suitable installation angle, the mounting frame 14 is installed on the dam body to facilitate stable installation of the barrel 1. Then, the double-headed electric cylinder 4 moves the multiple clamping blocks 3 through the two-person linkage frame 5, two pushing columns 6, two pushing plates 7, multiple pushing bars 8 and multiple pushing rods, so that the multiple clamping blocks 3 release the clamping of the gate body 2. Then, the gate body 2 is pushed downward by the two double-headed electric cylinders 4 to move the gate body 2 out of the barrel 1 for use.

[0050] 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.
