DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0033] Referring to the drawings in the description Figures 1-10 A concrete pipeline connecting system, comprising a construction vehicle 1, a driving part 2 is installed at the bottom of the construction vehicle 1, a frame 3 is installed at the output end below the driving part 2, injection devices 4 are arranged at the bottom of the frame 3 on both sides, the injection devices 4 comprise arc-shaped guide rods 41, the arc-shaped guide rods 41 are movably inserted into the bottom of the frame 3, baffles 42 are fixedly installed at the bottom end of the arc-shaped guide rods 41, conveying pipes 43 are connected to the side away from the other group of injection devices 4 of the baffles 42, a conveying pump 9 is installed on the construction vehicle 1, and the conveying pipes 43 are in communication with the output end of the conveying pump 9; the concrete pipeline connecting system further comprises a driving device 5; when the spigots 201 and the sockets 202 of two concrete pipelines 200 are movably inserted into each other and are supported on a pipe pillow 100, the pipe pillow 100 and the two concrete pipelines 200 form an arc-shaped space 101 therebetween, the baffles 42 of the two groups of injection devices 4 are driven by the driving device 5 to extend into the interior of the arc-shaped space 101 from both ends of the arc-shaped space 101, so that the conveying pump 9 pumps concrete into the arc-shaped space 101 through the conveying pipes 43.

[0034] In the embodiment, as Figure 7As shown, the driving device 5 comprises a motor 51 fixedly installed in the frame 3 and a gear 52 arranged between the two sets of arc-shaped guide rods 41 of the injection devices 4, one side of the arc-shaped guide rod 41 is provided with a tooth 411, the two sets of arc-shaped guide rods 41 are engaged with the gear 52 through the tooth 411, and the motor 51 has an output shaft 510, and the motor 51 drives the gear 52 to rotate through the output shaft 510.

[0035] It should be noted that in the above technical solution, the arc-shaped guide rod 41 of each set of injection devices 4 is provided with two arc-shaped guide rods, which are movably inserted into the bottom of the frame 3. Among them, the arc-shaped guide rod 41 close to the gear 52 is provided with a tooth 411, and the gear 52 is engaged with the arc-shaped guide rod 41 through the tooth 411, so that when the motor 51 rotates, the two arc-shaped guide rods 41 can be driven to move simultaneously through the gear 52.

[0036] In this embodiment, the specific implementation is: during construction, first excavate the trench, level and tamp the trench bottom, and lay and level the sand cushion. First, use hoisting equipment such as a crane to hoist a plurality of pipe pillows 100 to the specified position of the trench, and then hoist the concrete pipe 200, so that the concrete pipe 200 is supported on the pipe pillow 100, and the spigot 201 and the socket 202 of the concrete pipe 200 are inserted and installed with each other. Then use the system to construct, and pour concrete on the connection of the two concrete pipes 200. Specifically, after moving the construction vehicle 1 to the specified position, the driving part 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; the motor 51 drives the gear 52 to rotate, and the gear 52 drives the two arc-shaped guide rods 41 to move, so that the two arc-shaped guide rods 41 drive the two baffles 42 to move downward, respectively, the two baffles 42 enter the inside of the arc-shaped space 101 from both ends of the arc-shaped space 101, and the two baffles 42 abut each other; the mixed concrete is conveyed from the conveying pipe 43 to the space between the two baffles 42 by the conveying pump 9, and because the concrete between the two baffles 42 is more and more, the two baffles 42 are pushed to both sides by the concrete, in this process, the motor 51 can be reversed to drive the gear 52, and the two baffles 42 gradually move out of the arc-shaped space 101. When the two baffles 42 move out of the inside of the arc-shaped space 101, the inside of the arc-shaped space 101 is filled with concrete. The driving part 2 can adopt a pneumatic cylinder or a hydraulic cylinder.

[0037] It should be noted that the connection of the two concrete pipes 200 is not limited to the part of the arc-shaped space 101, and the part above the arc-shaped space 101 also needs to be poured with concrete, which is operated manually. Manual operation does not need to set up a formwork, so it can save cost, and manual operation will not take too long.

[0038] The above technical solution, by setting up an injection device 4 and a driving device 5, uses the driving device 5 to drive the baffles 42 of the two sets of injection devices 4 into the interior of the arc-shaped space 101 and fit them together. When pouring concrete, as the concrete is poured, the two baffles 42 gradually move out of the arc-shaped space 101. That is, by adopting the method of pouring from the middle of the arc-shaped space 101 to both sides, a large amount of air can be avoided from accumulating in the middle of the arc-shaped space 101. After pouring, vibration is not required, ensuring the sealing, stability and durability of the connection between the two concrete pipes 200.

[0039] 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 them. 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 two speeds. Therefore, in the further solution of this embodiment, the following improvements are made.

[0040] Refer to the instruction manual appendix Figures 6-7 A clutch assembly 53 is provided between the output shaft 510 and the gear 52. The clutch assembly 53 includes a rotating shaft 531, which is fixedly connected to the middle of the gear 52. A sleeve 532 is fixedly connected to the upper end of the rotating shaft 531. Pressure plates 533 are fixedly connected to both sides of the upper end of the sleeve 532. The two pressure plates 533 are attached to the grooves on the outer surface of the output shaft 510.

[0041] Furthermore, a rotating sleeve 534 is fitted onto the upper end of the sleeve 532, and a tapered hole 535 is opened in the middle of the rotating sleeve 534. Two pressure plates 533 are located inside the tapered hole 535. A cylinder 536 is installed inside the frame 3, and the output end of the cylinder 536 is fixedly connected to the rotating ring on the outside of the rotating sleeve 534.

[0042] It should be noted that the rotating ring is rotatably connected to the outside of the rotating sleeve 534. Through the extension and retraction of the cylinder 536, the rotating ring can drive the rotating sleeve 534 to move up and down. When the rotating sleeve 534 moves upward, it pushes the upper end of the pressure plate 533 into the groove on the side wall of the output shaft 510 through the tapered hole 535; when the rotating sleeve 534 moves downward, the pressure plate 533, under its own elastic force, moves out of the groove on the side wall of the output shaft 510. Figure 7 In the indicated state, the tapered hole 535 presses the upper end of the pressure plate 533 into the groove on the side wall of the output shaft 510. At this time, the motor 51 can drive the pressure plate 533, sleeve 532, rotating sleeve 534, and rotating shaft 531 to rotate through the output shaft 510. The rotating shaft 531 drives the arc-shaped guide rod 41 to move. When the pressure plate 533 moves out of the side wall of the output shaft 510, the arc-shaped guide rod 41 can move freely.

[0043] In this embodiment, the implementation method is as follows: During construction, cylinder 536 first moves the rotating sleeve 534 upward via the rotating ring, causing the tapered hole 535 to press the pressure plate 533 into the groove on the side wall of the output shaft 510, so that the motor 51 can drive the gear 52 to rotate. 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 injected between the two baffles 42, cylinder 536 moves the rotating sleeve 534 downward, causing the pressure plate 533 to move out of the groove on the side wall of the output shaft 510. At this time, the rotation of the shaft 531 and the gear 52 is not affected by the motor 51. That is to say, when concrete is injected, the concrete can push the two baffles 42 to both sides, causing the two baffles 42 to gradually move out of the arc-shaped space 101.

[0044] The above technical solution uses a clutch assembly 53 to connect or disconnect the power between the motor 51 and the gear 52. When connected, the motor 51 drives the baffle 42 into the arc-shaped space 101. When disconnected, the baffle 42 can be gradually pushed out of the arc-shaped 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 a large amount of air entering due to the baffle 42 moving too fast will not occur.

[0045] Furthermore, such as Figure 4 and Figure 5 As shown, the cross-section of the arc-shaped space 101 is an irregular cross-section A. The edge of the baffle 42 has a gap with the edge of the irregular cross-section A. An arc-shaped extension cylinder 44 is fixedly connected to the side of the baffle 42 away from the other set of injection devices 4. The outer cross-sectional shape of the arc-shaped extension cylinder 44 is the same as the cross-sectional shape of the baffle 42.

[0046] It should be noted that since the surfaces of the concrete pipe 200 and the curved space 101 are relatively rough, if the outer wall of the baffle 42 is made to fit completely against the inner wall of the curved space 101, the friction between the baffle 42 and the inner wall of the curved space 101 may be too large, causing it to get stuck and unable to move out. Therefore, the baffle 42 is made smaller, that is, the edge of the baffle 42 is separated from the edge of the irregular section A, to ensure that the problem of getting stuck will not occur.

[0047] Furthermore, such as Figure 5 and Figure 6 As shown, in order to prevent concrete from flowing out of the gap and the baffle 42 from being pushed out of the way when pouring concrete, a sealing device 6 is provided. Specifically, a sealing device 6 is provided on one side of both sets of injection devices 4. The sealing device 6 includes a pressure plate 61, which is used to press on the surface of the upper end of the pipe rest 100. The arc-shaped extension cylinder 44 moves through the arc-shaped extension cylinder 44, so that the pressure plate 61 closes the upper end of the arc-shaped space 101.

[0048] It should be noted that when the pressure plate 61 closes the upper end of the arc-shaped space 101, although the 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.

[0049] Furthermore, a mounting plate 62 is installed on the side wall of frame 3, and a cylinder 63 is fixedly installed at the bottom end of the mounting plate 62. The output end of cylinder 63 is fixedly connected to pressure plate 61.

[0050] It should be noted that since the upper surface of the pipe rest 100 is below the central axis of the concrete pipe 200, the pressure plate 61 cannot be moved vertically to press against the upper surface of the pipe rest 100 during construction, otherwise it would collide with the concrete pipe 200. Therefore, cylinder 63 is designed. In the initial state, the bottom ends of the baffle 42 and the arc-shaped extension cylinder 44 are rotated to above the pressure plate 61. Then, cylinder 63 drives the pressure plate 61 to move horizontally to both sides, and the driving component 2 drives the sealing device 6 to move vertically. When the pressure plate 61 contacts the surface of the pipe rest 100, cylinder 63 pushes the pressure plate 61 to move towards the center, so that the pressure plate 61 is completely pressed against the upper end of the pipe rest 100. Then, the driving device 5 drives the baffle 42 and the arc-shaped extension cylinder 44 to move downward. During the movement, the baffle 42 and the arc-shaped extension cylinder 44 can pass through the pressure plate 61.

[0051] Refer to the instruction manual appendix Figures 2-3 The construction vehicle 1 is equipped with an adjustment 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, which is used to drive the turntable 71 to rotate.

[0052] It should be noted that the power unit 72 is in the form of a motor plus a worm gear reducer. The power unit 72 drives the turntable 71 to rotate, which can adjust the position of the injection device 4 and adjust the baffle 42 to a suitable position.

[0053] Furthermore, a movable plate 81 is hinged to one side of the bottom of the turntable 71, and the drive component 2 is fixedly installed below the movable plate 81. A cylinder 3 8 is provided at the bottom of the turntable 71, and the fixed end and output end of the cylinder 3 8 are respectively hinged to the bottom surface of the turntable 71 and one side of the movable plate 81.

[0054] It should be noted that when not in use, the movable plate 81 can be rotated upward by the cylinder 3 8, thereby moving the drive component 2 and the injection device 4 to a horizontal state, which facilitates the movement of the construction vehicle 1 after being retracted.

[0055] Refer to the instruction manual appendix Figure 10 This embodiment also provides a construction method using the above-described concrete pipe connection system, including the following steps:

[0056] Step 1: Use hoisting equipment to hoist the pipe sleeper 100 and concrete pipe 200 to the designated position, so that the spigot 201 and socket 202 of the two concrete pipes 200 are connected to each other and supported on the pipe sleeper 100.

[0057] 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.

[0058] Step 3: Drive the arc-shaped guide rod 41 downward by the drive device 5, 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 fit together.

[0059] Step 4: Concrete is transported from the delivery pipe 43 to the space between the two baffles 42 by the delivery pump 9. The two baffles 42 gradually move out of the arc-shaped space 101 so that the concrete fills the arc-shaped space 101.

[0060] In conclusion, 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 within the protection scope of the present invention.
