[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0024] like Figure 1-4 As shown, a new type of channel type automatic cover provided by an embodiment of the utility model includes a cover, and also includes:

[0025] A crossbeam 3, wherein the crossbeam 3 is slidably arranged on the cover plate;

[0026] A spring 6, one end of the spring 6 is connected to the crossbeam 3, and the other end of the spring 6 is connected to the cover plate;

[0027] Clamp hooks 1, a plurality of clamp hooks 1 are hinged on both sides of the crossbeam 3;

[0028] An airbag 2, wherein the airbag 2 is arranged between the crossbeam 3 and the cover plate;

[0029] The rubber strip is arranged between the cover plate and the mold; the function of the rubber strip is to form a seal between the cover plate and the mold to prevent leakage of concrete when pouring concrete, thereby ensuring the quality of the pipe segment.

[0030] In the embodiment of the present utility model, the overall workflow is as follows:

[0031] The cover plate is closed downwards, and the airbag 2 is lifted up, so that the crossbeam 3 is lifted up. The rise of the crossbeam 3 drives the clamp 1 to rotate, so that the clamp 1 hooks the edge of the mold. The lifting force of the airbag 2 and the hook relay of the clamp 1 work together to make the cover plate and the mold tightly closed, and pour concrete into the mold through the discharge port 4 to cast the pipe segment. In this process, the rubber strip installed in the sealing channel 5 ensures that the joint between the cover plate and the mold is well sealed to prevent leakage and ensure the quality of the pipe segment. After the casting is completed, the airbag 2 is deflated, and the crossbeam 3 descends under its own gravity and the action of the spring 6. The clamp 1 releases the mold, and the cover plate can be opened, completing a production cycle.

[0032] like Figure 1-3 As shown, as a preferred embodiment of the utility model, contact seats 7 are fixedly connected to both sides of the cover plate, and the clamping hook 1 is movably abutted against the contact seat 7.

[0033] In the embodiment of the utility model, in the initial state, the clamping hook 1 abuts against the contact point on the top of the contact seat 7 , and when the crossbeam is lifted, the clamping hook 1 is separated from the contact seat 7 .

[0034] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the utility model, a slide seat 8 is fixedly connected to the cover plate, and a crossbeam 3 is slidably connected inside the slide seat 8.

[0035] In the embodiment of the utility model, a slot for the movement of the cross beam 3 is provided in the slide seat 8. When the cross beam 3 is lifted or reset, the slide seat 8 is guided.

[0036] like Figure 4 As shown, as a preferred embodiment of the utility model, a sealing groove 5 is opened on the mold, and the rubber strip is installed in the sealing groove 5.

[0037] In the embodiment of the utility model, when the sealing rubber part is worn or damaged, the use of the sealing channel 5 with a new structure makes it simple and quick to replace the rubber part, which is the key to improving production efficiency and preventing slurry leakage.

[0038] like Figure 1 As shown, as a preferred embodiment of the utility model, a feed opening 4 is provided on the cover plate for pouring concrete into the mold.

[0039] The working principle of the utility model is:

[0040] When the new type of automatic groove cover is used, the cover is closed downwards, and the airbag 2 is lifted up, so that the crossbeam 3 is lifted up. The rise of the crossbeam 3 drives the clamp 1 to rotate, so that the clamp 1 hooks the edge of the mold. The lifting force of the airbag 2 and the hook relay force of the clamp 1 work together to make the cover and the mold tightly closed, and pour concrete into the mold through the discharge port 4 to cast the pipe segment. In this process, the rubber strip installed in the sealing groove 5 ensures that the joint between the cover and the mold is well sealed to prevent leakage and ensure the quality of the pipe segment. After the casting is completed, the airbag 2 is deflated, the crossbeam 3 is lowered, the clamp 1 releases the mold, and the cover can be opened, completing a production cycle.

[0041] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
