[0002] Concrete pipes are a type of prefabricated or cast-in-place pipe widely used in municipal, construction, water conservancy and other fields. They are mainly made of cement, aggregates (sand and gravel), water and additives.

[0003] When laying concrete pipes, first dig a trench to ensure that the base is flat and compacted, then lay a sand and gravel cushion layer on the base and level it to disperse the load. Use lifting equipment to lower the pipe section by section steadily, insert the spigot of the concrete pipe into the socket, and then pour concrete at the connection to enhance the sealing, stability and durability of the interface.

[0004] The current method is to use a pipe pillow to support the connection of the concrete pipe. There is a space in the support part of the pipe pillow for pouring concrete. The pouring method adopted is to directly inject concrete into it. However, since the space is an arc-shaped space, concrete is poured from both sides of the pipe pillow. A large amount of air is easily accumulated in the middle of the space, and it is impossible to extend the vibrator into it, resulting in poor sealing, stability and durability of the connection of the concrete pipe. Summary of the Invention

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention.

[0029] Refer to the instruction manual Figures 1-10 A concrete pipe connection system includes a construction vehicle 1, a driving component 2 is installed at the bottom of the construction vehicle 1, a frame 3 is installed at the output end below the driving component 2, and injection devices 4 are provided on both sides of the bottom of the frame 3. The injection device 4 includes an arc-shaped guide rod 41, which is movably plugged into the bottom of the frame 3. A baffle 42 is fixedly installed at the bottom end of the arc-shaped guide rod 41. A delivery pipe 43 is connected to the side of the baffle 42 away from another group of injection devices 4. A delivery pump 9 is installed on the construction vehicle 1, and the delivery pipe 4 3 is connected to the output end of the delivery pump 9; the concrete pipe connection system also includes a driving device 5; when the sockets 201 and the sockets 202 of the two concrete pipes 200 are plugged into each other and supported on the pipe pillow 100, an arc-shaped space 101 is formed between the pipe pillow 100 and the two concrete pipes 200, and the driving device 5 drives the baffles 42 of the two sets of injection devices 4 to extend from both ends of the arc-shaped space 101 into the interior of the arc-shaped space 101, so that the delivery pump 9 pumps concrete into the arc-shaped space 101 through the delivery pipe 43.

[0030] In this embodiment, if Figure 7As shown, the driving device 5 includes a motor 51 and a gear 52. The motor 51 is fixedly installed in the frame 3. The gear 52 is arranged between the arc-shaped guide rods 41 of the two groups of injection devices 4. A gear tooth 411 is provided on one side of the arc-shaped guide rod 41. The two groups of arc-shaped guide rods 41 are engaged with the gear 52 through the gear tooth 411. The motor 51 has an output shaft 510, and the motor 51 drives the gear 52 to rotate through the output shaft 510.

[0031] It should be noted that in the above technical solution, two arcuate guide rods 41 are provided for each set of injection devices 4, both of which are movably connected to the bottom of the frame 3. One of the arcuate guide rods 41 near the gear 52 is provided with gear teeth 411, and the gear 52 engages with the arcuate guide rod 41 through the gear teeth 411. Therefore, when the motor 51 rotates, the gear 52 can drive the two arcuate guide rods 41 to move simultaneously.

[0032] In this embodiment, the specific implementation method is as follows: During construction, a trench is first excavated, the trench base is leveled and compacted, and a sand and gravel cushion layer is laid and leveled. Multiple pipe sleepers 100 are first hoisted to the designated location in the trench using lifting equipment such as a crane. Concrete pipes 200 are then hoisted, supported on the pipe sleepers 100, and the spigots 201 and sockets 202 of the concrete pipes 200 are connected and installed. Then, using this system, concrete is poured at the joint between the two concrete pipes 200. Specifically, after the construction vehicle 1 is moved to the designated position, the driving component 2 drives the injection device 4 downward until the central axis of the curved guide rod 41 coincides with the central axis of the concrete pipe 200. The motor 51 drives the gear 52 to rotate, which drives the two curved guide rods 41 to move, causing the two curved guide rods 41 to respectively drive the two baffles 42 downward. The two baffles 42 enter the interior of the curved space 101 from both ends, and the two baffles 42 are in contact with each other. The mixed concrete is delivered from the delivery pipe 43 to the space between the two baffles 42 by the delivery pump 9. As the amount of concrete between the two baffles 42 increases, the two baffles 42 are pushed to the sides by the concrete. During this process, the motor 51 can drive the gear 52 to reverse, and the two baffles 42 gradually move out of the curved space 101. When the two baffles 42 move out of the interior of the curved space 101, the interior of the curved space 101 is filled with concrete. The driving component 2 can be a pneumatic cylinder or a hydraulic cylinder.

[0033] It should be noted that the connection between the two concrete pipes 200 is not limited to the part of the arc space 101. The part above the arc space 101 also needs to be poured with concrete. Manual operation is used at this position. Manual operation does not require the establishment of a formwork, which can save costs, and manual operation will not take too long.

[0034] The above technical solution is provided with an injection device 4 and a driving device 5, and the driving device 5 is used to drive the baffles 42 of the two sets of injection devices 4 into the interior of the arc space 101 and fit them together. When pouring concrete, as the concrete is poured, the two baffles 42 gradually move out of the arc space 101 along with the concrete, that is, the method of pouring from the middle of the arc space 101 to both sides is adopted, which can avoid the accumulation of a large amount of air in the middle of the arc space 101. No vibration is required after pouring, thereby ensuring the sealing, stability and durability of the connection between the two concrete pipes 200.

[0035] In the above technical solution, when concrete is injected between the two baffles 42, the driving device 5 is required to actively drive the two baffles 42 to gradually move out of the arc-shaped space 101. If the baffles 42 move too fast, a large amount of air will easily enter therein. Therefore, the moving speed of the arc-shaped space 101 is affected by the pumping speed of the delivery pump 9, and it is difficult to match the speeds of the two. Therefore, in a further solution of this embodiment, the following improvements are made.

[0036] Refer to the instruction manual Figure 6-Figure 7 A clutch assembly 53 is provided between the output shaft 510 and the gear 52. The clutch assembly 53 includes a rotating shaft 531. The rotating shaft 531 is fixedly connected to the middle part of the gear 52. The upper end of the rotating shaft 531 is fixedly connected to a sleeve 532. Both sides of the upper end of the sleeve 532 are fixedly connected to pressing plates 533. The two pressing plates 533 are attached to the groove on the outer surface of the output shaft 510.

[0037] Furthermore, a rotating sleeve 534 is provided on the upper end of the sleeve 532, a conical hole 535 is opened in the middle of the rotating sleeve 534, two pressing plates 533 are located in the conical hole 535, and a cylinder 536 is provided inside the frame 3, and the output end of the cylinder 536 is fixedly connected to the rotating ring outside the rotating sleeve 534.

[0038] It should be noted that the swivel is rotatably connected to the outside of the swivel sleeve 534. Through the expansion and contraction of the cylinder 1 536, the swivel can drive the swivel sleeve 534 to move up and down. When the swivel sleeve 534 moves upward, the upper end of the pressing piece 533 can be pushed into the groove of the side wall of the output shaft 510 through the tapered hole 535; when the swivel sleeve 534 moves downward, the pressing piece 533 moves out of the groove of the side wall of the output shaft 510 under the action of its own elastic force. Figure 7 In the illustrated state, the tapered hole 535 presses the upper end of the pressing piece 533 against the groove in the side wall of the output shaft 510. At this point, the motor 51, via the output shaft 510, can drive the pressing piece 533, the sleeve 532, the rotating sleeve 534, and the rotating shaft 531 to rotate, and the rotating shaft 531 drives the arcuate guide rod 41 to move. When the pressing piece 533 moves out of the side wall of the output shaft 510, the arcuate guide rod 41 can move freely.

[0039] In this embodiment, the specific implementation is as follows: during construction, first, cylinder 1 536 drives the rotating sleeve 534 upward through the rotating ring, causing the tapered hole 535 to press the pressing plate 533 into the groove on the side wall of the output shaft 510, allowing the motor 51 to drive the gear 52 to rotate, and the gear 52 drives the arc-shaped guide rod 41 and the baffle 42 to move into the interior of the arc-shaped space 101. When concrete is poured between the two baffles 42, cylinder 1 536 drives the rotating sleeve 534 downward, causing the pressing plate 533 to move out of the groove on the side wall of the output shaft 510. At this time, the rotation of the rotating shaft 531 and the gear 52 is not affected by the motor 51. In other words, when concrete is poured, the concrete can press the two baffles 42 toward each other, causing the two baffles 42 to gradually move out of the arc-shaped space 101.

[0040] The above technical solution is used to connect or disconnect the power between the motor 51 and the gear 52 by setting a clutch assembly 53. When connected, the motor 51 drives the baffle 42 into the arc space 101. When disconnected, the baffle 42 can be gradually pushed out of the arc space 101 by the concrete. In this way, the concrete pumping speed can be matched with the moving speed of the baffle 42, and the problem of the baffle 42 moving too fast and entering a large amount of air will not occur.

[0041] Furthermore, if Figure 4 and Figure 5 As shown, the cross-section of the arc-shaped space 101 is an irregular cross-section A, and there is a gap between the edge of the baffle 42 and the edge of the irregular cross-section A. The side of the baffle 42 away from the other group of injection devices 4 is fixedly connected with an arc-shaped epitaxial tube 44, and the outer cross-sectional shape of the arc-shaped epitaxial tube 44 is the same as the cross-sectional shape of the baffle 42.

[0042] It should be noted that since the surfaces of the concrete pipe 200 and the arc-shaped space 101 are relatively rough, if the outer wall of the baffle 42 is completely in contact with the inner wall of the arc-shaped space 101, the baffle 42 may have a large friction with the inner wall of the arc-shaped space 101, causing the baffle 42 to get stuck and unable to be removed. Therefore, the baffle 42 is set smaller, that is, there is a gap between the edge of the baffle 42 and the edge of the special-shaped section A to ensure that the problem of getting stuck does not occur.

[0043] Furthermore, if Figure 5 and Figure 6 As shown, in order to prevent the concrete from flowing out from the gap and the baffle 42 from being pushed poorly when pouring concrete, a sealing device 6 is provided. Specifically, a sealing device 6 is provided on one side of the two groups of injection devices 4. The sealing device 6 includes a pressure plate 61. The pressure plate 61 is used to press on the surface of the upper end of the tube pillow 100. The arc-shaped extension tube 44 moves through the arc-shaped extension tube 44, so that the pressure plate 61 closes the upper end of the arc-shaped space 101.

[0044] It should be noted that when the pressing plate 61 closes the upper end of the arc-shaped space 101 , although concrete can flow into the gap, it will not flow into the arc-shaped space 101 . During the concrete injection process, the baffle 42 can still be pushed outward.

[0045] Furthermore, a mounting plate 62 is installed on the side wall of the frame 3 , and a second cylinder 63 is fixedly installed on the bottom end of the mounting plate 62 . The output end of the second cylinder 63 is fixedly connected to the pressure plate 61 .

[0046] It should be noted that since the upper surface of the pipe sleeper 100 is below the central axis of the concrete pipe 200, the pressure plate 61 cannot directly move vertically to press on the upper surface of the pipe sleeper 100 during construction, otherwise it will collide with the concrete pipe 200. Therefore, the design of cylinder 2 63 is adopted. In the initial state, the bottom ends of the baffle 42 and the arc-shaped extension tube 44 are rotated above the pressure plate 61. Then, cylinder 2 63 drives the pressure plate 61 to move horizontally to both sides, and the driving component 2 drives the blocking device 6 to move vertically. When the pressure plate 61 contacts the surface of the pipe sleeper 100, cylinder 2 63 further pushes the pressure plate 61 toward the middle, so that the pressure plate 61 is completely pressed on the upper end of the pipe sleeper 100. Then, the driving device 5 drives the baffle 42 and the arc-shaped extension tube 44 to move downward. During the movement, the baffle 42 and the arc-shaped extension tube 44 can pass through the pressure plate 61.

[0047] Refer to the instruction manual Figure 2-Figure 3 The construction vehicle 1 is equipped with an adjusting device 7, which includes a turntable 71 rotatably mounted on the bottom of the construction vehicle 1. A power component 72 is fixedly mounted on the construction vehicle 1, and the power component 72 is used to drive the turntable 71 to rotate.

[0048] It should be noted that the power component 72 is in the form of a motor plus a worm gear reducer. By driving the turntable 71 to rotate through the power component 72, the position of the injection device 4 can be adjusted and the baffle 42 can be adjusted to a suitable position.

[0049] Furthermore, a movable plate 81 is hinged on one side of the bottom of the turntable 71, the driving component 2 is fixedly installed below the movable plate 81, and a cylinder three 8 is provided at the bottom of the turntable 71, and the fixed end and output end of the cylinder three 8 are hinged to the bottom surface of the turntable 71 and one side of the movable plate 81 respectively.

[0050] It should be noted that when not in use, the movable plate 81 can be driven to rotate upward by the cylinder 3 8, so that the driving component 2 and the injection device 4 move to a horizontal state, and after being folded up, it is convenient to move the construction vehicle 1.

[0051] Refer to the instruction manual Figure 10 This embodiment also provides a construction method using the above-mentioned concrete pipe connection system, including the following steps: Step 1: Use lifting equipment to lift the pipe pillow 100 and the concrete pipe 200 to the designated location, so that the sockets 201 and the sockets 202 of the two concrete pipes 200 are plugged into each other and supported on the pipe pillow 100; Step 2: After the construction vehicle 1 moves to the designated position, the driving component 2 drives the injection device 4 to move downward until the central axis of the arc-shaped guide rod 41 coincides with the central axis of the concrete pipe 200; Step 3: The driving device 5 drives the arc-shaped guide rod 41 to rotate downward, so that the baffle 42 enters the interior of the arc-shaped space 101, and the baffles 42 of the two sets of injection devices 4 are attached to each other; Step 4: The concrete is delivered from the delivery pipe 43 to between the two baffles 42 by the delivery pump 9 , and the two baffles 42 are gradually moved out of the arc-shaped space 101 so that the concrete fills the arc-shaped space 101 .

[0052] Finally: The above description is only a preferred embodiment of the present invention and is 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 scope of protection of the present invention.
