Description

Technical Field

[0001] This utility model relates to the technical field of subway construction, and in particular to a pouring device for subway construction. Background Technology

[0002] Concrete pouring is a crucial step in subway construction, directly impacting the stability and durability of the subway structure. Temperature control of the concrete is paramount during construction. Due to the large size of subway stations, the concrete generates significant heat of hydration during hardening, potentially leading to temperature cracks.

[0003] A related technology, CN215443161U, discloses a concrete pouring device for subway civil construction, comprising a discharge pipe, a fixed cylinder on the surface of the discharge pipe, an external gear ring fixedly connected to the surface of the fixed cylinder, an installation cylinder rotatably connected to the surface of the fixed cylinder and located outside the external gear ring, and an adjustment mechanism on the surface of the installation cylinder, the adjustment mechanism including a limiting cylinder, the left end of the limiting cylinder being rotatably connected to the installation cylinder via a rotating shaft, and the right end of the limiting cylinder being fixedly connected to an operating rod, the operating rod having an installation cavity inside. This utility model relates to the field of civil construction technology. In this concrete pouring device for subway civil construction, the limiting teeth engage with the external gear ring under the action of a first spring, effectively preventing the operating rod from rotating around the fixed cylinder during use, facilitating the operator to apply force to the discharge pipe, and making it easy to adjust the discharge angle of the discharge pipe via the operating rod. It is highly practical and conducive to widespread use.

[0004] The concrete pouring device described above transports concrete to a fixed cylinder via a discharge pipe, and then uses an adjusting structure to move the concrete from the fixed cylinder to the pouring position. During transport, concrete is prone to segregation due to gravity and uneven mixing, resulting in uneven internal composition. This not only affects the concrete's performance but also leads to a decrease in the strength and durability of the poured concrete, which is particularly critical in demanding projects such as subways. Utility Model Content

[0005] This utility model solves the problems in related technologies and proposes a pouring device for subway construction, which realizes convenient equipment movement, efficient filtration and mixing, precise material delivery, and dust reduction, greatly improving the efficiency and quality of concrete pouring operations during subway construction.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a pouring device for subway construction, comprising a support base, movable wheels disposed at the four corners of the lower end face of the support base, a support frame fixedly disposed on one side of the support base, a support plate disposed at the middle position of the support frame, a rotatable hopper disposed above the support plate, a sealing cover plate disposed on the upper end face of the hopper, a feed inlet disposed on the upper end face of the sealing cover plate, a filter plate disposed at the middle position of the inner cavity of the hopper, and an installation stop disposed at the connection between the filter plate and the hopper. The system comprises: a ring, a discharge port located at the middle of the lower end face of the storage hopper, a conveying pipe connected to the discharge port, a support plate located between the lower end face of the conveying pipe and the support base, an inlet pipe located on the conveying pipe relative to the discharge port, a transition pipe located between the inlet pipe and the discharge port, a water inlet pipe connected to the transition pipe, a spiral conveying shaft located in the inner cavity of the conveying pipe, a drive assembly for rotating the storage hopper and the spiral conveying shaft, and a discharge pipe located at the other end of the conveying pipe, wherein the discharge pipe is externally connected to the casting equipment.

[0007] By adopting the above technical solution and utilizing the movable wheel design, the equipment can be flexibly moved to the pouring position, adapting to the needs of the complex environment of subway construction. The drive component can drive the rotation of the storage hopper and the screw conveyor shaft. The rotation of the storage hopper helps to fully mix the filtered material, preventing impurities from accumulating on the filter screen and affecting the filtration effect. The filter plate and mounting ring inside the storage hopper work together to ensure the filtration effect. The filtered material enters the transition pipe through the discharge port. The transition pipe is connected to the external water inlet pipe, which can realize the addition of water for mixing and conveying of materials, as well as effectively reduce dust. The screw conveyor shaft is responsible for stirring and mixing the mixed concrete material to prevent segregation and accurately conveying it to the pouring equipment.

[0008] As a preferred embodiment, the discharge port passes through the support plate and is rotatably connected to the transition pipe. A sealed bearing is provided at the connection between the discharge port and the support plate, and a rotating groove adapted to the discharge port is provided in the inner cavity of the transition pipe.

The second pulley is connected to one end of the screw conveyor shaft, and both ends of the screw conveyor shaft are connected to the two ends of the inner cavity of the conveying pipe through sealed bearings.

[0011] By adopting the above technical solution, when the drive motor drives the second pulley to rotate, the gear connected to the drive shaft rotates through the transmission belt, the first pulley, and the drive shaft, which in turn drives the external gear ring to rotate, and then drives the storage hopper to rotate. The rotational motion of the external gear ring is transmitted to the drive shaft through the gear, and then through the first pulley and the drive belt on the drive shaft to the second pulley, ultimately driving the screw conveyor shaft to rotate. The two ends of the screw conveyor shaft are connected to the two ends of the conveying pipe cavity through sealed bearings. When the screw conveyor shaft rotates, it can smoothly transport materials from the storage hopper along the conveying pipe to the target position, achieving efficient material transfer and ensuring the stability and reliability of the entire system.

[0012] As a preferred embodiment, the drive motor is fixedly mounted on the outside of the support frame, and the output shaft of the drive motor is connected to the screw conveyor shaft through a reducer.

[0013] By adopting the above technical solution, the drive motor is fixedly arranged outside the support frame. The drive motor is connected to the screw conveyor shaft through its output shaft. When the drive motor is powered on, it can drive the screw conveyor shaft to rotate, thereby realizing the material conveying task.

[0014] As a preferred embodiment, the filter plate is detachably connected to the mounting retaining ring, and the sieve hole size of the filter plate matches the maximum particle size of the concrete aggregate.

[0015] By adopting the above technical solution, impurities and excessively large particles in concrete can be filtered out, thus ensuring the quality of the concrete.

[0016] As a preferred embodiment, the conveying pipeline is also equipped with a flow sensor and a pressure sensor. The flow sensor is used to monitor the concrete conveying flow rate in real time, and the pressure sensor is used to monitor the pressure inside the conveying pipeline.

[0017] By adopting the above technical solution, staff can adjust the conveying speed and pressure in a timely manner by monitoring data to ensure the uniform delivery of concrete.

[0018] As a preferred embodiment, it also includes rollers evenly arranged on the lower end face of the storage hopper and guide grooves arranged on the support plate that are adapted to the rollers.

[0019] By adopting the above technical solution, the design of the roller and guide groove facilitates the guidance of the roller's movement direction, thereby effectively ensuring the stability of the storage hopper during rotation.
