Description

Technical Field

[0001] This utility model relates to the field of drainage engineering, and in particular to a concrete pipe installation and positioning mechanism for drainage engineering. Background Technology

[0002] Concrete pipes for drainage engineering are one of the core infrastructures of urban and rural drainage systems. They are mainly used to collect and transport various types of wastewater, rainwater, and surface runoff. Through a structured pipe network, fluids are transported to treatment plants or safe discharge areas, ultimately achieving the functions of "pollution control, flood prevention, and environmental protection." Generally, before installing concrete pipes, a pit is dug at a suitable location. This pit is the pre-embedded pit for the concrete pipes, and the concrete pipes will be installed in this pre-embedded pit. Conventionally, the pipes are directly placed into the pre-embedded pit and then connected. However, during the installation process, the pipes are prone to shifting, which can affect the installation of each section.

[0003] Chinese Patent Publication No. CN221591954U discloses a stabilizing structure for the installation and positioning of reinforced concrete pipes. This solution provides effective fixation of the pipes by setting up a fixing frame and cooperating with a locking mechanism for fixing the insert plate. However, the stabilizing structure for the installation and positioning of the pipes mentioned in the above patent cannot be fixed in position to the pre-embedded pit during the installation process. If the concrete pipe moves, it will cause the stabilizing structure to move as well, which may affect the installation of the concrete pipes.

[0004] Therefore, we propose a concrete pipe installation and positioning mechanism for drainage engineering. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a concrete pipe installation and positioning mechanism for drainage projects. Through motor-driven worm gear and worm wheel transmission, the rotating shaft, rotating arm, and reciprocating arm are linked together, ultimately achieving automatic movement of the slider and side support plate. This eliminates the need for manual adjustment of the clamping structure, significantly reducing the physical exertion of installers. Simultaneously, the meshing structure of the worm gear and worm has a self-locking characteristic, effectively preventing the side support plate from loosening due to external forces after clamping. Combined with the large-area contact of the L-shaped side support plate with the inner wall of the pre-embedded pit, the mechanism can be firmly fixed within the pit, preventing positioning deviation from affecting pipe installation accuracy and ensuring the overall stability and reliability of the fixing.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A concrete pipe installation and positioning mechanism for drainage engineering includes a fixing component, a support component at the top of the fixing component; the fixing component includes a reinforcing plate, a rotating shaft rotatably connected to the center of the reinforcing plate, the bottom end of the rotating shaft passing through the bottom end of the reinforcing plate and fixedly connected to a rotating arm, reciprocating arms rotatably connected to both ends of the rotating arm, a slider rotatably connected to the reinforcing plate at the end of the reciprocating arm away from the rotating arm, a connecting plate fixedly connected to the end of the slider away from the reciprocating arm, a side support plate fixedly connected to the end of the connecting plate away from the slider, and a cover plate fixedly connected to the top of the reinforcing plate above the rotating shaft;

[0008] The reinforcing plate serves as the basic load-bearing component, providing a stable installation platform for other parts. The rotating shaft, rotating arm, and reciprocating arm form a transmission linkage structure, which converts the rotational motion of the rotating shaft into the pushing and pulling motion of the reciprocating arm. This, in turn, drives the side support plate to move via the slider and connecting plate, achieving a tight fixation against the installation environment. This allows the entire device to be securely locked in the concrete pre-embedded pit, achieving the desired positioning effect. The cover plate protects the internal rotating shaft and other components, preventing impurities from affecting their operation. The overall device achieves stable fixing and transmission functions for the fixed components. Meanwhile, the support components provide load-bearing support for the concrete pipe. The two work together to construct the basic structural framework required for pipe installation and positioning, facilitating the subsequent placement of the concrete pipe on the device for installation.

[0009] Furthermore, the top end of the rotating shaft passes through the top end of the reinforcing plate and is fixedly connected to a worm gear;

[0010] By setting a worm gear at the top of the shaft, a reliable power receiving component is provided for the shaft. The worm gear can cooperate with the subsequent transmission structure to achieve effective power transmission, ensuring that the shaft can stably obtain rotational power, thereby ensuring the normal operation of the entire fixed component transmission system. At the same time, the worm gear structure also has a certain self-locking performance, which can prevent the shaft from rotating randomly in a non-powered state and improve the stability of the fixed component.

[0011] Furthermore, the cover plate is rotatably connected to a worm gear that meshes with a worm wheel;

[0012] The worm gear, which meshes with the worm wheel, serves as an intermediate transmission component, transmitting external power to the worm wheel to drive the rotating shaft. This ensures that the rotating shaft drives subsequent components such as the rotating arm. At the same time, the worm wheel and worm gear have self-locking properties, which can reduce the possibility of the side support plate loosening due to external forces to a certain extent.

[0013] Furthermore, a motor is fixedly connected to the outer wall of the cover plate, and the transmission end of the motor extends into the interior of the cover plate and is fixedly connected to the worm gear.

[0014] Furthermore, the bottom end of the reinforcing plate is provided with a groove adapted to the rotating arm.

[0015] Furthermore, two symmetrical sliding grooves that are slidably connected to the slider are provided at the bottom end of the reinforcing plate and on both the left and right sides of the groove.

[0016] Furthermore, the side support plate is L-shaped.

[0017] Furthermore, the support assembly includes a fixing block fixedly installed on the top of the cover plate, and a pipe support pad is fixedly connected to the top of the fixing block.

[0018] Furthermore, the pipe support pad is arc-shaped.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. The worm gear and worm wheel drive, driven by a motor, move the rotating shaft, rotating arm, and reciprocating arm in a coordinated manner, ultimately achieving automatic movement of the slider and side support plate. This eliminates the need for manual adjustment of the clamping structure, significantly reducing the physical exertion of installers. Simultaneously, the meshing structure of the worm wheel and worm gear has a self-locking characteristic, effectively preventing the side support plate from loosening due to external forces after clamping. Combined with the large-area contact of the L-shaped side support plate with the inner wall of the pre-embedded pit, the mechanism can be firmly fixed within the pit, preventing positioning deviations from affecting pipeline installation accuracy and ensuring the overall stability and reliability of the fixation.

[0021] 2. The pipe support pads in the support assembly are designed with an arc-shaped structure. Their contours are adapted to the height of the outer wall of the concrete pipe, which maximizes the contact area between the pads and the pipe, ensuring that the pipe is subjected to uniform force during placement and avoiding excessive local stress that could damage the outer wall of the pipe. In addition, the arc-shaped structure can also provide natural restraint for the pipe, preventing it from sliding laterally along the surface of the pads or falling off during the support process. This provides a safe and stable bearing foundation for pipe hoisting, docking, and other installation procedures, reducing the risk of damage during pipe installation. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0030] Reference Figures 1 to 5 As shown, a concrete pipe installation and positioning mechanism for drainage engineering is provided in a preferred embodiment of the present invention. It includes a fixing component 1, and a support component 2 is provided at the top of the fixing component 1. The fixing component 1 includes a reinforcing plate 101, and a rotating shaft 105 is rotatably connected to the center of the reinforcing plate 101. The bottom end of the rotating shaft 105 passes through the bottom end of the reinforcing plate 101 and is fixedly connected to a rotating arm 109. Reciprocating arms 110 are rotatably connected to both the front and rear ends of the rotating arm 109. A slider 111 that is rotatably connected to the reinforcing plate 101 is rotatably connected to the end of the reciprocating arm 110 away from the rotating arm 109. A connecting plate 103 is fixedly connected to the end of the slider 111 away from the reciprocating arm 110. A side support plate 104 is fixedly connected to the end of the connecting plate 103 away from the slider 111. A cover plate 102 is fixedly connected to the top of the reinforcing plate 101 and above the rotating shaft 105.

[0031] The reinforcing plate 101 serves as the basic load-bearing component, providing a stable installation platform for other parts. The rotating shaft 105, rotating arm 109, and reciprocating arm 110 form a transmission linkage structure, which can convert the rotational motion of the rotating shaft 105 into the pushing and pulling motion of the reciprocating arm 110. This, in turn, drives the side support plate 104 to move through the slider 111 and connecting plate 103, achieving a tight fixation against the installation environment. This allows the entire device to be well-positioned within the concrete pre-embedded pit. The cover plate 102 protects the internal rotating shaft 105 and other components, preventing impurities from affecting the operation of the components. Overall, the fixed component 1 achieves stable fixation and transmission functions. Meanwhile, the support component 2 provides load-bearing support for the concrete pipe. The two work together to construct the basic structural framework required for pipe installation and positioning, facilitating the subsequent placement of the concrete pipe on this device for installation.

[0032] The top end of the rotating shaft 105 passes through the top end of the reinforcing plate 101 and is fixedly connected to the worm gear 106;

[0033] By setting a worm gear 106 at the top of the rotating shaft 105, a reliable power receiving component is provided for the rotating shaft 105. The worm gear 106 can cooperate with the subsequent transmission structure to realize the effective transmission of power, ensuring that the rotating shaft 105 can stably obtain rotational power, thereby ensuring the normal operation of the entire fixed component 1 transmission system. At the same time, the worm gear 106 structure also has a certain self-locking performance, which can prevent the rotating shaft 105 from rotating arbitrarily in a non-powered state, thereby improving the stability of the fixed component 1.

[0034] The cover plate 102 is rotatably connected to a worm 107 that meshes with a worm gear 106;

[0035] The worm 107, which meshes with the worm gear 106, serves as an intermediate transmission component, transmitting external power to the worm gear 106 to drive the rotating shaft 105 to rotate. This ensures that the rotating shaft 105 drives subsequent components such as the rotating arm 109 to operate. At the same time, the worm gear 106 and the worm 107 have self-locking properties, which can reduce the possibility of the side support plate 104 loosening due to external forces to a certain extent.

[0036] A motor 108 is fixedly connected to the outer wall of the cover plate 102. The transmission end of the motor 108 extends into the interior of the cover plate 102 and is fixedly connected to the worm gear 107.

[0037] By setting up a motor 108 and connecting it to the worm gear 107, an automated power source is provided for the transmission system of the entire fixed assembly 1, replacing manual drive. By controlling the motor 108, the speed and direction of the worm gear 107 can be precisely adjusted, thereby controlling the rotation state of the rotating shaft 105, making the movement of the side support plate 104 more precise and controllable, and improving the automation level and positioning accuracy of the mechanism.

[0038] The bottom end of the reinforcing plate 101 is provided with a groove for adapting to the rotating arm 109;

[0039] The groove at the bottom of the reinforcing plate 101 that adapts to the rotating arm 109 provides ample space for the rotation of the rotating arm 109, preventing the rotating arm 109 from colliding or rubbing against the reinforcing plate 101 during rotation, and ensuring that the rotating arm 109 can operate flexibly and smoothly.

[0040] The bottom end of the reinforcing plate 101 and on both the left and right sides of the groove are provided with two symmetrical sliding grooves that are slidably connected to the slider 111.

[0041] The sliding connection between the bottom groove of the reinforcing plate 101 and the slider 111 provides precise guidance for the movement of the slider 111, ensuring that the slider 111 can only move smoothly along the direction of the groove.

[0042] The side support plate 104 is L-shaped;

[0043] The L-shaped side support plate 104 increases the contact area with the installation environment, improves the friction during clamping and fixing, and makes the fixing effect more firm and reliable. At the same time, the L-shaped structure can better adapt to the corner positions in the installation environment, enhance the applicability of the mechanism in different installation scenarios, and ensure stable clamping and fixing under various working conditions.

[0044] The support component 2 includes a fixing block 201 fixedly installed on the top of the cover plate 102, and a pipe support pad 202 is fixedly connected to the top of the fixing block 201.

[0045] The fixing block 201 of the support component 2 connects the cover plate 102 and the pipe support pad 202, and can stably fix the pipe support pad 202 to the top of the cover plate 102. The pipe support pad 202 is in direct contact with the concrete pipe, providing a stable support for the pipe and preventing the pipe from shaking or falling during installation. At the same time, the cooperation between the fixing block 201 and the pipe support pad 202 can keep the pipe at a suitable installation height and position, providing a guarantee for the subsequent pipe docking installation.

[0046] The pipe support pad 202 is arc-shaped;

[0047] The arc-shaped pipe support pad 202, whose shape matches the outer contour of the concrete pipe, increases the contact area with the pipe, making the support force on the pipe more uniform and avoiding damage to the pipe due to excessive local stress. At the same time, the arc-shaped structure can also play a certain role in limiting the pipe and preventing the pipe from falling during the support process.

[0048] Specific implementation process: First, the positioning mechanism is transported to the concrete pipe installation site, and its position is initially adjusted according to the size of the pre-embedded pit. The reinforcing plate 101 is placed horizontally on the pre-set flat base at the bottom of the pre-embedded pit, ensuring that the cover plate 102 is facing upwards and the support component 2 is located in the bearing area at the top of the mechanism. At the same time, the front and rear sets of side abutment plates 104 are aligned with the inner wall of the pre-embedded pit to prepare for subsequent tight fixing. Next, the power system of the fixing component 1 is started to achieve stable fixing of the mechanism and the pre-embedded pit: the motor 108 on the outer wall of the cover plate 102 is opened, and the transmission end of the motor 108 drives the worm gear 107 fixedly connected to it. The pit rotates inside the pre-embedded pit of the cover plate 102; since the pre-embedded pit of the worm gear 107 meshes with the pre-embedded pit of the worm wheel 106 at the top of the pre-embedded pit of the rotating shaft 105, the rotational power of the pre-embedded pit of the worm gear 107 is transmitted to the pre-embedded pit of the worm wheel 106, thereby driving the pre-embedded pit of the rotating shaft 105 to rotate synchronously around the central axis of the pre-embedded pit of the reinforcing plate 101. As the pre-embedded pit of the rotating shaft 105 rotates, the pre-embedded pit of the rotating arm 109 fixed at its bottom end rotates synchronously in the groove at the bottom end of the pre-embedded pit of the reinforcing plate 101: the pre-embedded pit of the reciprocating arm 110 connected by the pin at both ends of the pre-embedded pit of the rotating arm 109 is pushed and pulled accordingly. Since the end of the pre-embedded pit of the reciprocating arm 110 away from the pre-embedded pit of the rotating arm 109 is rotatably connected to the pre-embedded pit of the slider 111, and the pre-embedded pit of the slider 111 is embedded Within the groove at the bottom of the pre-embedded pit of the reinforcing plate 101, the circular motion of the pre-embedded pit of the rotating arm 109 is converted into the linear push-pull motion of the pre-embedded pit of the reciprocating arm 110, thereby driving the pre-embedded pit of the slider 111 to slide along the groove away from the center of the pre-embedded pit of the reinforcing plate 101. When the pre-embedded pit of the slider 111 moves, it drives the pre-embedded pit of the connecting plate 103 to move towards the inner wall of the pre-embedded pit simultaneously, until the vertical section of the pre-embedded pit of the L-shaped side abutment plate 104 is in close contact with the inner wall of the pre-embedded pit and the horizontal section is in contact with the bottom base surface of the pre-embedded pit. At this time, the pre-embedded pit of the motor 108 is turned off, and the self-locking characteristics of the pre-embedded pit of the worm gear 106 and the worm 107 are used to prevent the pre-embedded pit of the rotating shaft 105 from rotating in the opposite direction and causing the side abutment to be damaged. The pre-embedded pit of support plate 104 is loosened, thus firmly fixing the entire positioning mechanism in the pre-embedded pit, completing the positioning and fixing process of the mechanism itself. Subsequently, the concrete pipe is hoisted and supported: the concrete pipe to be installed is slowly hoisted by the lifting equipment, the pipe posture is adjusted so that its axis is consistent with the installation direction, and then the pipe is slowly lowered onto the pipe support pad 202 pre-embedded pit of support component 2; since the pre-embedded pit of pipe support pad 202 is arc-shaped, its inner wall matches the outer wall contour of the concrete pipe, and the pipe can naturally fit the arc-shaped pad after being lowered, achieving uniform force support. At the same time, the arc structure plays a limiting role for the pipe, preventing the pipe from sliding laterally along the surface of the pad. Finally, the pipe can be installed.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
