[0015] As a further technical solution of the present invention, a sliding groove used in conjunction with the blocking plate is provided on the fixing seat, and a circular material passing groove is provided on the lower end surface of the blocking plate and on one side close to the inner movable plate.

[0016] A working method of a device for quickly blocking a vault pouring port, the specific operating steps of the method are:

[0017] Step 1: When preparing for pouring, the external material supply pipe is sleeved on the connecting nozzle, and the blocking plate drives the inner moving plate to approach the injection pipe. At this time, the blocking state between the blocking plate and the fixed seat changes from the blocking state to the connecting state. During the movement of the blocking plate, the left clamping plate and the right clamping plate approach each other until the left clamping plate and the right clamping plate are clamped and embraced on the rubber nozzle of the external material supply pipe;

[0018] Step 2: After pouring is completed, the blocking plate drives the inner movable plate to gradually move away from the injection pipe, and the blocking plate and the fixed seat change from a connected state to a blocked state. During this process, the right clamping plate will reciprocate and collide with the outer wall of the external feed pipe.

[0019] Beneficial effects of the present invention:

[0020] 1. When the end of the external feed pipe is sleeved on the connecting nozzle, the blocking plate is close to the injection pipe. At this time, the blocking state between the blocking plate and the fixed seat changes to a connected state. During the movement of the blocking plate, the inner moving plate and the left clamping plate will be driven to move together. When the blocking plate is translated, it will eventually drive the right clamping plate to approach the left clamping plate through the linkage assembly, and the left clamping plate and the right clamping plate will approach each other until the left clamping plate and the right clamping plate are clamped and embraced on the rubber nozzle of the external feed pipe. On the one hand, the external feed pipe is supported and limited to prevent the external feed pipe from falling off the connecting nozzle during use. On the other hand, the external feed pipe and the connecting nozzle are more tightly connected to avoid a gap between the two and leakage.

[0021] 2. When the pouring operation is completed, the blocking plate drives the inner moving plate away from the injection tube. During this process, the flip plate rotates counterclockwise. During this process, the spring 1 recovers from the extended state to the normal state, thereby driving the right clamping plate away from the left clamping plate. During the process of the blocking plate driving the inner moving plate away from the injection tube, the contact switch is in the power-on standby state. During this process, the contact wheel 3 will pass through each trapezoidal block in turn. Each time the contact wheel 3 contacts the trapezoidal block, the contact wheel 3 and the connecting seat 3 will move into the side groove under the contact limit of the trapezoidal block. During this process, the connecting seat 3 will squeeze the spring 2, and the spring 2 will store elastic potential energy, and The end of the connecting seat three will contact the contact switch, and the contact switch will send an electrical signal to control the electromagnet to be energized. The energized electromagnet will generate magnetic attraction to attract the iron block, thereby causing the iron block to approach the electromagnet, thereby driving the right clamping plate to approach the left clamping plate. During this process, the left clamping plate will collide with the outer wall of the external feed pipe. Under the action of this impact force, the connecting nozzle and the injection pipe will vibrate slightly, thereby causing the concrete adhering to the inner wall of the connecting nozzle and the injection pipe to quickly fall into the external feed pipe, avoiding this part of the concrete from adhering and condensing on the inner wall of the connecting nozzle and the injection pipe. In the long run, it will affect the delivery capacity of the connecting nozzle and the injection pipe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0031] Reference Figure 1 and Figure 2When pouring the vault, the external feed pipe is sleeved on the connecting nozzle 4, and then the blocking plate 5 is converted to an open state. At this time, the external feed pipe, the connecting nozzle 4, the injection pipe 3 and the injection channel in the fixed seat 2 are in a connected state, and then the external feed pipe starts to feed, and the concrete is guided by the connecting nozzle 4, the injection pipe 3 and the fixed seat 2 and filled to the specified position. When the concrete filling and pouring is completed, the blocking plate 5 blocks the injection channel of the fixed seat 2, and then the excess concrete in the injection pipe 3 falls into the external feed pipe under the action of gravity, and then the external feed pipe is removed from the connecting nozzle 4. This method is a prior art.

[0032] When the external feeding pipe is spliced ​​and connected with the connecting nozzle 4 , the end of the external feeding pipe is in the shape of a rubber nozzle, which is sleeved on the connecting nozzle 4 to wrap the connecting nozzle 4 .

[0033] Reference Figure 1 and Figure 3 When the end of the external feeding pipe is sleeved on the connecting nozzle 4, the sealing plate 5 drives the inner movable plate 6 to approach the injection pipe 3. At this time, the sealing plate 5 and the fixed seat 2 change from a blocked state to a connected state. During the movement of the sealing plate 5, the inner movable plate 6 and the left clamping plate 7 will be driven to move together. When the sealing plate 5 is translated, it will eventually drive the right clamping plate 10 to approach the left clamping plate 7 through the linkage assembly. The left clamping plate 7 and the right clamping plate 10 approach each other until the left clamping plate 7 and the right clamping plate 10 are clamped and embraced on the rubber nozzle of the external feeding pipe. On the one hand, the external feeding pipe is supported and limited to prevent the external feeding pipe from falling off the connecting nozzle 4 during use. On the other hand, the external feeding pipe and the connecting nozzle 4 are more closely connected to avoid a gap between the two and leakage.

[0034] Reference Figure 3 A plurality of guide rods 12 are fixed to one side of the right clamping plate 10 close to the mounting seat 9, and each guide rod 12 is movably inserted into the mounting seat 9. A plurality of springs 13 are fixed between the right clamping plate 10 and the mounting seat 9, and each spring 13 is movably sleeved on the outer side wall of the corresponding guide rod 12.

[0035] Reference Figure 3 The linkage assembly includes a flip plate 14 rotatably arranged between the two mounting frames 8, a connecting seat 15 is fixed to one side of the blocking plate 5, and a plurality of interference wheels 16 are rotatably arranged on the side wall of the connecting seat 15, a connecting seat 2 17 is fixed to the end of each guide rod 12, and a interference wheel 2 18 is rotatably arranged on the side wall of each connecting seat 2 17.

[0036] Reference Figure 3When the blocking plate 5 drives the inner moving plate 6 to approach the injection tube 3, it will drive the connecting seat 15 and the contact wheel 16 to move together. After the blocking plate 5 moves a certain distance, the blocking plate 5 will drive the connecting seat 15 and the contact wheel 16 to contact the flip plate 14. During this process, the flip plate 14 will rotate clockwise by a certain angle. During the rotation of the flip plate 14, the side wall of the lower section will contact the contact wheel 2 18. After the contact wheel 2 18 is subjected to force, it will push the connecting seat 2 17, the guide rod 12 and the right clamping plate 10 to approach the left clamping plate 7, until the right clamping plate 10 and the left clamping plate 7 are clamped and embraced on the outer wall of the end of the external feeding tube. During this process, the spring 13 is stretched and deformed to store elastic potential energy.

[0037] Reference Figure 3 When pouring is completed, the blocking plate 5 drives the inner moving plate 6 to gradually move away from the injection pipe 3, and the blocking plate 5 and the fixed seat 2 change from a connected state to a blocked state. At this time, the blocking plate 5 drives the connecting seat 15 and the contact wheel 16 away from the flip plate 14. At this time, the elastic potential energy stored in the spring 13 is released, driving the right clamping plate 10, the guide rod 12, the connecting seat 2 17 and the contact wheel 2 18 to return to the initial position. In this process, the contact wheel 2 18 contacts the flip plate 14, causing the flip plate 14 to rotate counterclockwise to the initial position.

[0038] Reference Figure 3 An outer movable plate 19 is fixed to the other side of the blocking plate 5, a fixed block 20 is fixed to the inner top of the arch template 1, a cylinder 21 is fixed to the lower end surface of the fixed block 20, and the end of the telescopic end of the cylinder 21 is fixedly connected to the outer movable plate 19.

[0039] Reference Figure 3 The telescopic end of the oil cylinder 21 is in a contracted state in the initial state, and the blocking plate 5 is in a blocking state at this time. When the telescopic end of the oil cylinder 21 is extended, the blocking plate 5 will be pushed to move horizontally through the outer movable plate 19, so that the blocking plate 5 is changed from the blocking state to the connecting state.

[0040] Reference Figure 3 and Figure 4 The adsorption component includes two plug-in rods 22 symmetrically fixed on the side wall of the left clamping plate 7, and an electromagnet 23 is fixed at the end of each plug-in rod 22. Two plug-in grooves 24 for cooperating with the plug-in rods 22 are symmetrically opened on the inner wall of the right clamping plate 10, and an iron block 25 is fixed on the inner wall of each plug-in groove 24. A contact unit for cooperating with the electromagnet 23 is provided on the inner moving plate 6.

[0041] Reference Figure 5The contact unit includes a side groove 26 opened on one side of the inner movable plate 6, a connecting seat 3 27 is movably arranged in the side groove 26, a contact wheel 3 28 is rotatably arranged on the side wall of the connecting seat 3 27, a plurality of springs 29 are fixed between the connecting seat 3 27 and the inner wall of the side groove 26, a contact switch 30 is fixed on the inner wall of the side groove 26, a connecting plate 31 is fixed on one side of the fixed seat 2, and a plurality of trapezoidal blocks 32 are fixed on the side wall of the connecting plate 31.

[0042] Reference Figure 3 , Figure 5 and Figure 6 When the left clamping plate 7 and the right clamping plate 10 are close to each other, the plug-in rod 22 will be inserted into the plug-in slot 24 with the electromagnet 23. The cooperation between the plug-in rod 22 and the plug-in slot 24 can prevent the left clamping plate 7 and the right clamping plate 10 from moving in the Y direction during use. During the contact and engagement process between the left clamping plate 7 and the right clamping plate 10, the contact switch 30 is in a power-off state. At this time, the contact switch 30 is not working. When the left clamping plate 7 approaches the right clamping plate 10, the inner moving plate 6 drives the connecting seat three 27 and the contact wheel three 28 to move to the specified position of the connecting plate 31. During this process, the contact wheel three 28 passes over each trapezoidal block 32.

[0043] Reference Figure 3 , Figure 5 and Figure 6 When the pouring operation is completed, the blocking plate 5 drives the inner movable plate 6 away from the injection tube 3. During this process, the flip plate 14 rotates counterclockwise. During this process, the spring 13 recovers from the extended state to the normal state, thereby driving the right clamping plate 10 away from the left clamping plate 7. During the process of the blocking plate 5 driving the inner movable plate 6 away from the injection tube 3, the contact switch 30 is in the power-on standby state. During this process, the contact wheel three 28 will pass through each trapezoidal block 32 in turn. Each time the contact wheel three 28 contacts the trapezoidal block 32, the contact wheel three 28 and the connecting seat three 27 will move into the side groove 26 under the contact limit of the trapezoidal block 32. During this process, the connecting seat three 27 will squeeze the spring two 29. The spring two 29 stores elastic potential energy, and the end of the connecting seat three 27 will contact the contact switch 30.

[0044] Reference Figure 3 , Figure 5 and Figure 6At this time, the contact switch 30 sends an electrical signal to control the electromagnet 23 to be energized. The energized electromagnet 23 generates a magnetic attraction to attract the iron block 25, thereby prompting the iron block 25 to approach the electromagnet 23, thereby driving the right clamping plate 10 to approach the left clamping plate 7. During this process, the left clamping plate 7 will collide with the outer wall of the external feed pipe. Under the action of this impact force, the connecting nozzle 4 and the injection pipe 3 will vibrate slightly, thereby prompting the concrete adhering to the inner walls of the connecting nozzle 4 and the injection pipe 3 to quickly fall into the external feed pipe, avoiding this part of the concrete from adhering and condensing on the inner walls of the connecting nozzle 4 and the injection pipe 3. In the long run, it affects the delivery volume of the connecting nozzle 4 and the injection pipe 3. When the right clamping plate 10 contacts the outer wall of the external feed pipe, the spring 13 is stretched and deformed again to store elastic potential energy.

[0045] Reference Figure 3 , Figure 5 and Figure 6 When the contact wheel three 28 passes over a trapezoidal block 32, the trapezoidal block 32 no longer contacts the contact wheel three 28. At this time, the elastic potential energy stored in the squeezed and contracted spring two 29 is released, pushing the connecting seat three 27 away from the contact switch 30. At this time, the electromagnet 23 is powered off, and the iron block 25 and the right clamping plate 10 are away from the outer wall of the external feeding pipe under the action of the elastic potential energy of the spring one 13. When the contact wheel three 28 contacts and passes over the next trapezoidal block 32, the corresponding trapezoidal block 32 again contacts the contact wheel three 28 and the connecting seat three 27, and the connecting seat three 27 moves to contact the contact switch 30. The contact switch 30 controls the electromagnet 23 to be energized again, so that the right clamping plate 10 approaches and collides with the outer wall of the external feeding pipe again. The right clamping plate 10 will repeat the above action several times until the contact wheel three 28 is completely away from the connecting plate 31, and the insertion rod 22 is completely away from the insertion slot 24.

[0046] Reference Figure 2 A sliding groove for cooperating with the blocking plate 5 is provided on the fixed seat 2 , and a circular material passage groove 33 is provided on the lower end surface of the blocking plate 5 and on one side close to the inner movable plate 6 .

[0047] Reference Figure 2 In the initial state, the circular material passage 33 is away from the injection tube 3. At this time, the circular material passage 33 is staggered with the fixed seat 2. At this time, the blocking plate 5 is in a blocking state, and the side wall of the blocking plate 5 blocks the injection channel of the fixed seat 2. When the blocking plate 5 drives the inner moving plate 6 to approach the injection tube 3, the circular material passage 33 is connected with the injection channel of the fixed seat 2, and the blocking plate 5 and the fixed seat 2 are in a connected state.

[0048] A working method of a device for quickly blocking a vault pouring port, the specific operating steps of the method are:

[0049] Step 1: When preparing for pouring, the external material supply pipe is sleeved on the connecting nozzle 4, and the blocking plate 5 drives the inner moving plate 6 to approach the injection pipe 3. At this time, the blocking state between the blocking plate 5 and the fixing seat 2 changes from the blocking state to the connecting state. During the movement of the blocking plate 5, the left clamping plate 7 and the right clamping plate 10 approach each other until the left clamping plate 7 and the right clamping plate 10 are clamped and embraced on the rubber nozzle of the external material supply pipe;

[0050] Step 2: After pouring is completed, the blocking plate 5 drives the inner movable plate 6 to gradually move away from the injection pipe 3, and the blocking plate 5 and the fixed seat 2 change from a connected state to a blocked state. During this process, the right clamping plate 10 will reciprocate and collide with the outer wall of the external feed pipe.

[0051] When the present invention is used, refer to Figure 1 and Figure 2 When pouring the vault, the external feed pipe is sleeved on the connecting nozzle 4, and then the blocking plate 5 is switched to an open state. At this time, the external feed pipe, the connecting nozzle 4, the injection pipe 3 and the injection channel in the fixed seat 2 are in a connected state, and then the external feed pipe starts to feed, and the concrete is guided by the connecting nozzle 4, the injection pipe 3 and the fixed seat 2 and filled to the specified position. When the concrete filling and pouring is completed, the blocking plate 5 blocks the injection channel of the fixed seat 2, and then the excess concrete in the injection pipe 3 falls into the external feed pipe under the action of gravity, and then the external feed pipe is removed from the connecting nozzle 4. This method is a prior art;

[0052] Reference Figure 2 and Figure 3 When the end of the external feeding pipe is sleeved on the connecting nozzle 4, the blocking plate 5 drives the inner movable plate 6 to approach the injection pipe 3. At this time, the blocking plate 5 and the fixed seat 2 change from a blocked state to a connected state. During the movement of the blocking plate 5, the inner movable plate 6 and the left clamping plate 7 will be driven to move together. When the blocking plate 5 is translated, it will eventually drive the right clamping plate 10 to approach the left clamping plate 7 through the linkage assembly. The left clamping plate 7 and the right clamping plate 10 approach each other until the left clamping plate 7 and the right clamping plate 10 are clamped and embraced on the rubber nozzle of the external feeding pipe. On the one hand, the external feeding pipe is supported and limited to prevent the external feeding pipe from falling off the connecting nozzle 4 during use. On the other hand, the external feeding pipe and the connecting nozzle 4 are more closely connected to avoid a gap between the two and leakage.

[0053] Reference Figure 3When the left clamping plate 7 and the right clamping plate 10 are close to each other, the plug-in rod 22 will carry the electromagnet 23 and insert into the plug-in slot 24. The plug-in rod 22 cooperates with the plug-in slot 24 to prevent the left clamping plate 7 and the right clamping plate 10 from moving in the Y direction during use. During the contact and engagement process between the left clamping plate 7 and the right clamping plate 10, the contact switch 30 is in a power-off state. At this time, the contact switch 30 is not working. When the left clamping plate 7 is close to the right clamping plate 10, the inner moving plate 6 drives the connecting seat 3 27 and the contact wheel 3 28 to move to the specified position of the connecting plate 31. During this process, the contact wheel 3 28 passes over each trapezoidal block 32.

[0054] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 When the pouring operation is completed, the blocking plate 5 drives the inner movable plate 6 away from the injection tube 3. During this process, the flip plate 14 rotates counterclockwise. During this process, the spring 13 recovers from the extended state to the normal state, thereby driving the right clamping plate 10 away from the left clamping plate 7. During the process in which the blocking plate 5 drives the inner movable plate 6 away from the injection tube 3, the contact switch 30 is in the power-on standby state. During this process, the contact wheel 3 28 will pass through each trapezoidal block 32 in sequence. Each time the contact wheel 3 28 contacts the trapezoidal block 32, the contact wheel 3 28 and the connecting seat 3 27 will move into the side groove 26 under the contact limit of the trapezoidal block 32. During this process, the connecting seat 3 27 will squeeze the spring 29, the spring 29 stores elastic potential energy, and the end of the connecting seat 3 27 will contact the contact switch 30.

[0055] Reference Figure 3 , Figure 4 and Figure 5 At this time, the contact switch 30 sends an electrical signal to control the electromagnet 23 to be energized. The energized electromagnet 23 generates a magnetic attraction to attract the iron block 25, thereby causing the iron block 25 to approach the electromagnet 23, thereby driving the right clamping plate 10 to approach the left clamping plate 7. During this process, the left clamping plate 7 will collide with the outer wall of the external feed pipe. Under the action of this impact force, the connecting nozzle 4 and the injection pipe 3 will vibrate slightly, thereby causing the concrete adhering to the inner walls of the connecting nozzle 4 and the injection pipe 3 to quickly fall into the external feed pipe, preventing this part of the concrete from adhering to and condensing on the inner walls of the connecting nozzle 4 and the injection pipe 3. In the long run, the conveying amount of the connecting nozzle 4 and the injection pipe 3 is affected. When the right clamping plate 10 contacts the outer wall of the external feed pipe, the spring 13 is stretched and deformed again to store elastic potential energy.

[0056] Reference Figure 3 , Figure 5 and Figure 6When the contact wheel three 28 passes over a trapezoidal block 32, the trapezoidal block 32 no longer contacts the contact wheel three 28. At this time, the elastic potential energy stored in the squeezed and contracted spring two 29 is released, pushing the connecting seat three 27 away from the contact switch 30. At this time, the electromagnet 23 is powered off. Under the action of the elastic potential energy of the spring one 13, the iron block 25 and the right clamping plate 10 are away from the outer wall of the external feeding pipe. When the contact wheel three 28 contacts and passes over the next trapezoidal block 32, the corresponding trapezoidal block 32 again contacts the contact wheel three 28 and the connecting seat three 27. The connecting seat three 27 moves to contact the contact switch 30. The contact switch 30 controls the electromagnet 23 to be energized again, so that the right clamping plate 10 approaches and collides with the outer wall of the external feeding pipe again. The right clamping plate 10 will repeat the above actions several times until the contact wheel three 28 is completely away from the connecting plate 31. At this time, the insertion rod 22 completely leaves the insertion slot 24.
