Description

Technical Field

[0001] The invention belongs to the field of concrete precast mold casting of water transport and water conservancy projects, and particularly relates to a concrete casting device for water transport and water conservancy projects and a use method thereof. Background Art

[0002] The construction of water transport and water conservancy projects has many similarities with the construction of general civil engineering projects such as roads, railways, bridges and house buildings. During the construction of water transport and water conservancy projects, it is necessary to cast precast concrete molds, and when laying canals, precast panels are laid in foundation pits for construction.

[0003] Patent CN111347560A discloses a mixing device for water conservancy project construction, which is used to construct the side wall of the canal by pouring, and concrete is formed by a template, and the concrete is introduced into the foundation pit through a hopper, a guide trough, and a paving trough for pouring, so as to complete the side wall of the canal. However, although this method can be used to build standardized canals, the production and transportation of prefabricated panels occupy a large amount of production resources and needs to be improved. At the same time, during the laying of prefabricated panels, there are gaps between two adjacent prefabricated panels, which need to be filled. If the production process is unqualified, it will cause water leakage in the canal, which needs to be improved.

[0004] In addition, during the existing water transport and hydraulic concrete pouring process, due to the gaps between the stones in the concrete, bubbles appear in the concrete. The presence of bubbles causes the concrete to be loosely compacted, making the concrete products easy to break. During the pouring process of traditional concrete pouring equipment, workers need to hold a vibrating rod to vibrate and defoam the concrete, which is complicated to operate.

[0037] The present invention also provides a method for using the concrete pouring device based on any one of the above-mentioned water transport and water conservancy projects, comprising the following steps:

[0038] Step 1: Add concrete into the concrete mixing tank through the adding port, the servo motor of the mixing mechanism drives the mixing shaft to rotate, the mixing shaft drives the mixing rod and the mixing blade to rotate through the metal pipe, and the concrete is mixed by the mixing rod and the mixing blade;

[0039] Step 2, place the precast concrete mold on the inner side of the longitudinal U-shaped plate, and then turn the handle in sequence. The handle pushes the circular extrusion pad close to the precast concrete mold through the screw rod to squeeze and fix the precast concrete mold. At the same time, the longitudinal U-shaped plate moves downward under gravity, and the longitudinal U-shaped plate pushes the four vertical rods to move downward. The four vertical rods push the two fixing bars to move downward. The fixing bars pull the clamping plate close to the precast concrete mold through two diagonal support rods. The clamping plate drives the two horizontal sliding rods to slide on the horizontal U-shaped plate, and the precast concrete mold is clamped by the two clamping plates.

[0040] Step 3: The two linear motors of the discharge mechanism push the blocking strip to move, and the blocking strip drives the sealing plate to move, thereby releasing the seal of the rectangular discharge pipe, and the concrete is introduced into the interior of the conveying cylinder through the rectangular discharge pipe;

[0041] Step 4: The driving motor of the concrete conveying mechanism is started to drive the conveying shaft to rotate, and the conveying shaft drives the spiral blade to rotate to convey the concrete forward. The concrete is discharged into the interior of the concrete precast mold through the discharge pipe. As the weight of the concrete pouring increases, the clamping plates on both sides clamp the concrete precast mold more firmly under the action of gravity.

[0042] Step 5, at the same time, the transmission shaft drives the second pulley to rotate through the first pulley and the belt strip, the second pulley drives the transmission shaft to rotate, the transmission shaft drives the cam to rotate, the cam drives the first straight plate and the second straight plate to vibrate horizontally through the swing rod, so as to achieve the purpose of driving the precast mold fixing mechanism to vibrate reciprocatingly, and drives the concrete precast mold to vibrate while pouring concrete;

[0043] Step 6. After the processing is completed, use the sealing plate to seal the rectangular discharge pipe, reverse the handles in sequence so that the four circular extrusion pads leave the concrete precast mold, and then lift the concrete precast mold upward. The two clamping plates are reset and leave the concrete precast mold under the tension of the tension spring, and the concrete precast mold is removed.

[0044] Compared with the prior art, the present invention has the following beneficial effects:

[0045] (1) In this scheme, a servo motor is used to drive the stirring shaft to rotate, and the stirring shaft drives the stirring rod and stirring blades to rotate through a metal tube. The concrete is stirred by the stirring rod and stirring blades. The concrete precast mold is placed on the inner side of the longitudinal U-shaped plate, and then the four handles are rotated in sequence. The handles push the circular extrusion pad close to the concrete precast mold through the screw rod to squeeze and fix the concrete precast mold. At the same time, the longitudinal U-shaped plate moves downward due to gravity, and the longitudinal U-shaped plate pushes the four vertical rods to move downward. The four vertical rods push the two fixing bars to move downward. The fixing bars pull the clamping plate close to the concrete precast mold through two diagonal support rods. The clamping plate drives the two horizontal sliding rods to slide on the horizontal U-shaped plate. The concrete precast mold can be clamped by the two clamping plates, which is convenient and fast to fix the concrete precast mold.

[0046] (2) In this solution, two linear motors are used to push the blocking strip to move, and the blocking strip drives the sealing plate to move, thereby releasing the seal of the rectangular discharge pipe, and the concrete is introduced into the interior of the conveying cylinder through the rectangular discharge pipe;

[0047] (3) In this solution, the conveying shaft is driven to rotate by the driving motor, and the conveying shaft drives the spiral blade to rotate, so as to convey the concrete forward. The concrete is discharged into the interior of the concrete precast mold through the discharge pipe. As the weight of the concrete pouring increases, the clamping plates on both sides clamp the concrete precast mold more firmly under the action of gravity.

[0048] (4) This scheme uses the transmission shaft to drive the second pulley to rotate through the first pulley and the belt strip, the second pulley drives the transmission shaft to rotate, the transmission shaft drives the cam to rotate, and the cam drives the first straight plate and the second straight plate to vibrate horizontally through the swing rod, so as to achieve the purpose of driving the precast mold fixing mechanism to vibrate reciprocatingly, and drives the concrete precast mold to vibrate while pouring concrete, avoiding the workers holding the vibration rod to vibrate and defoam the concrete, thereby reducing the labor intensity;

[0049] (5) This solution uses a sealing plate to seal the rectangular discharge pipe, and reverses the four handles in sequence so that the four circular extrusion pads are separated from the concrete precast mold. Then the concrete precast mold is lifted upward, and the two clamping plates are reset and separated from the concrete precast mold under the tension of the tension spring, and the concrete precast mold can be removed;

[0050] (6) This solution relies on the concrete precast mold's own gravity to control the two clamping plates for limited clamping, and uses a spiral transmission method to transfer and pour concrete. As the weight of the concrete precast mold increases during pouring, the clamping plates on both sides clamp the concrete precast mold more firmly under the action of gravity. The vibration of the concrete precast mold is controlled by the power of the spiral transmission, which avoids the workers vibrating and defoaming the concrete with a hand-held vibrator, thereby reducing labor intensity.
