Description

Technical Field

[0001] The invention relates to the technical field of prefabricated component production equipment, and in particular discloses a vibration filling device for casting a prefabricated plate. Background Art

[0002] Precast panels are a type of concrete product that is processed and produced in a standardized, mechanized manner in a factory. During its manufacturing process, the mixed concrete is poured into a mold, and then cured and formed after being treated on a vibration table. The vibration compaction effect of the concrete in the mold largely determines the quality of the final precast panel product. The traditional concrete vibration compaction operation is mainly to insert a vibrating rod into the concrete manually. However, due to the large area of ​​the precast panel, the process of manually using a vibrating rod for compaction not only requires the operator to constantly change the position of the vibrating rod inserted into the concrete, resulting in a large amount of labor, but also the vibration compaction efficiency of the entire precast panel is low, which seriously restricts the production capacity of the precast panel production line.

[0003] The invention patent with application number 2019110373345 discloses an automatic vibration device for concrete precast stairs, including a moving track, a support frame, a vibration device and an electric control cabinet. The moving track includes a first track and an end beam. A running wheel is provided at one end of the end beam, and a first servo motor is provided on the outside. The support frame is arranged above the end beam. The vibration device includes a transmission mechanism, a vibration mechanism and a guide mechanism. The transmission mechanism includes a screw, a fixed seat, a second servo motor, a linear rail and a support plate. The vibration mechanism includes a vibration motor, a traction rope and a vibration rod. The guide mechanism includes a fixed pulley and a guide groove. Although the automatic vibration device disclosed in the invention patent can efficiently vibrate the concrete inside the mold to make it compact, its vibration and compaction effect is not ideal. This is because the centrifugal rotor in the vibration rod is arranged at the bottom of the rod shell, which causes the vibration rod to vibrate freely at the bottom and the vibration effect is obvious. However, the vibrating rods in the device always maintain the corresponding height after being inserted into the concrete. In addition, the size of the prefabricated wall panels is generally large, and the thickness of the panels is about 20 cm. As a result, after the multiple vibrating rods are inserted into the concrete, they can only vibrate the concrete at the corresponding depth. The upper or lower concrete cannot be treated with high-frequency vibration in the first place. It is necessary to extend the action time of the vibrating rods on the concrete to achieve the effect of vibration and filling, which ultimately limits the production efficiency of the entire prefabricated panel production line. Therefore, in view of the above-mentioned shortcomings of the existing automatic vibration device for concrete prefabricated stairs, the present application proposes a vibration and filling device for prefabricated panel casting that can effectively solve this technical problem. Summary of the invention

[0004] The present invention aims to provide a vibration filling device for precast slab casting, so as to realize rapid vibration filling of precast slab concrete, realize assembly line type efficient operation, and improve the production efficiency of the entire production line under the premise of ensuring the quality of precast slab products.

[0005] The present invention is achieved through the following technical solutions: A vibration filling device for casting precast panels comprises a mold-carrying vibration platform and a precast panel mold, a vibration rod filling mechanism is arranged directly above the precast panel mold, the vibration rod filling mechanism comprises a rectangular cover which is arranged to move up and down, slide rails are arranged at the left and right ends of the rectangular cover, a movable frame which extends out of the lower end opening of the rectangular cover is slidably arranged between the two slide rails, a conveying assembly which realizes the forward and backward movement of the movable frame is arranged in the rectangular cover, a row of vibration rods is inserted into the lower end of the movable frame, and two adjacent vibration rods are arranged to be staggered up and down, and a transmission mechanism which realizes the synchronous upward and downward reciprocating movement of a row of vibration rods during the forward and backward movement is arranged in the movable frame or the rectangular cover.

[0006] When the vibration filling device for casting precast panels disclosed in the present invention is in operation, the precast panel mold after pouring concrete is sent to the mold bearing vibration platform, which first vibrates it preliminarily so that the concrete is quickly leveled, and then the rectangular cover is pushed downward for a certain distance so that the lower end of a row of vibrating rods is inserted into the concrete. Then, after starting the vibrating rods, they are moved along the front end to the rear end of the precast panel mold, and during the movement, the row of vibrating rods are reciprocated up and down by the action of the transmission mechanism, and because two adjacent vibrating rods are staggered up and down, when the lower end of a row of vibrating rods moves in the concrete, it can perform comprehensive vibration filling treatment on each area and each layer depth, so that the bubbles in the concrete are quickly discharged, which not only greatly improves the vibration filling effect of the precast panel concrete, but also effectively guarantees the quality of the precast panel finally prepared.

[0007] As a first design scheme of the above-mentioned transmission mechanism, the transmission mechanism includes a crankshaft rotatably connected to a movable frame, and the middle section of the crankshaft is composed of a plurality of circumferentially staggered curved sections connected end to end in sequence, and the upper end of each of the vibration rods is provided with a movable rod rotatably connected to the corresponding curved section, gears are provided at both left and right ends of the crankshaft, and racks parallel to the slide rail and meshing with the gears are provided at both left and right ends of the rectangular cover.

[0008] The design of the above-mentioned transmission mechanism will make the crankshaft move synchronously during the forward and backward movement of the mobile frame, and can rotate the crankshaft through the meshing transmission between the gear and the rack at the end during the movement of the crankshaft. At this time, the upper end of each vibrating rod is connected to the crankshaft through a movable rod, so that the vibrating rod can reciprocate up and down during the movement, so that the lower end of the vibrating rod can interact with concrete of different depths, thereby accelerating the vibration filling rate of the concrete and ensuring the treated effect.

[0009] As a second design scheme of the above-mentioned transmission mechanism, the transmission mechanism includes a row of strip plates arranged in parallel left and right in a rectangular cover, the strip plates are provided with guide grooves which undulate up and down, and the crests or troughs of the guide grooves on two adjacent strip plates are staggered, and the upper end of each of the vibration rods is provided with a roller which acts on the guide groove on the corresponding strip plate.

[0010] As a further configuration of the above solution, the guide slot is shaped like a wave or a sawtooth.

[0011] The design of the above-mentioned transmission mechanism will also carry the vibrating rod up and down during the forward and backward movement of the movable frame, and the roller at the upper end of the vibrating rod is affected by the guide groove, which can make the vibrating rod reciprocate up and down during the forward and backward movement, so that the lower end of the vibrating rod interacts with concrete of different depths, thereby accelerating the vibration filling rate of the concrete and ensuring the treatment effect.

[0012] As a further configuration of the above scheme, sliders are provided on the slide rails on both sides, the two ends of the movable frame are connected to the corresponding sliders, the conveying assembly includes a transmission belt arranged at the left and right ends of the rectangular cover, the transmission belt is fixedly connected to the slider, and the two transmission belts are driven by the same motor.

[0013] The above structural design enables the two sliders to move forward and backward synchronously under the action of the transmission belt, thereby driving the moving frame and its vibrating rod to move forward and backward, and during the forward and backward movement, the vibrating rod is reciprocated up and down by the transmission mechanism.

[0014] As a further configuration of the above scheme, the vibrating rod filling mechanism also includes a gantry frame arranged across the mold bearing vibration platform, the upper end of the gantry frame is provided with a lifting device connected to the rectangular cover, and the rectangular cover is provided with a guide rod vertically penetrating the gantry frame. The above lifting device and the guiding role of the guide rod can make the entire vibrating rod filling mechanism move up and down stably according to the corresponding action steps.

[0015] As a further configuration of the above scheme, a row of guide cylinders are arranged at equal intervals on the movable frame, and the upper end of the vibrating rod passes through the guide cylinder and is movably arranged.

[0016] As a further configuration of the above scheme, the mold bearing vibration platform includes a bottom box seat and a bearing vibration seat, the upper surface of the bottom box seat is provided with a spring connected to the bearing vibration seat, and the bearing vibration seat is provided with a vibration motor.

[0017] As a further configuration of the above scheme, clamping members are rotatably provided at both the front and rear ends of the bearing vibration seat, and a telescopic driving member for driving the clamping member to rotate from a horizontal state to a vertical state is provided on the lower surface of the bearing vibration seat.

[0018] As a further configuration of the above scheme, a row of bearing wheels is provided at both left and right ends of the bearing vibration seat, and wheel axles are provided at both front and rear ends. A row of rubber wheels is provided on each wheel axle, and one end of the wheel axle is connected to a driving motor.

[0019] The above is a specific design scheme for the mold bearing vibration platform, which can ensure that the precast panel mold can be loaded and unloaded in an assembly line manner, and at the same time, the precast panel mold filled with concrete can be stably connected with the bearing vibration seat. Therefore, the high-frequency vibration effect of the vibration motor can be effectively transmitted to the precast panel mold and its concrete, so that the concrete in the precast panel mold can initially achieve the effect of vibration leveling, and in the subsequent process of using it in conjunction with the vibration rod filling mechanism, the vibration motor in the horizontal direction can be used to ensure that the surface of the final precast panel is vibrated and leveled to the optimal state, thereby improving the surface quality of the precast panel.

[0020] Compared with the prior art, the present invention has the following beneficial effects: The vibration filling device for casting precast panels disclosed in the present invention adopts a vibration rod filling mechanism with a special structural design, so that when processing the concrete in the mold, the lower ends of a row of vibration rods can simultaneously extend into the concrete at different depths, and the vibration rods can realize reciprocating motion during the subsequent movement, so that the row of vibration rods can perform comprehensive vibration filling processing on each area and each layer depth of the concrete, which not only improves the vibration filling efficiency of the concrete, but also can quickly discharge bubbles during the vibration filling process, thereby ensuring the quality of the precast panel product finally prepared.

[0021] The transmission mechanism interacting with the vibrating rod filling mechanism in the present invention adopts two specific design schemes. The first scheme can realize the up and down reciprocating motion of a row of vibrating rods through crankshaft and gear rack transmission, and the second scheme realizes the up and down reciprocating motion of a row of vibrating rods through the action of rollers and guide grooves. The two technical schemes are novel and ingenious in structural design, and both can be combined with the forward and backward movement process of the vibrating rod to realize the up and down reciprocating motion of the vibrating rod, effectively realizing the function to be achieved by the vibrating rod filling mechanism.

[0022] The present invention further designs a mold bearing vibration platform, which not only enables the precast panel mold to be loaded and unloaded in an assembly line manner, but also enables it to be stably connected to the bearing vibration seat after the precast panel mold is loaded, so that the high-frequency vibration on the bearing vibration seat can be fully transmitted to the concrete in the precast panel mold, thereby achieving initial vibration leveling of the concrete. In combination with the subsequent vibration rod vibration filling process, the vibration filling effect of the precast panel concrete can be greatly improved, thereby ensuring product quality.

[0031] Two slide rails 302 are arranged at the left and right ends of the rectangular cover 301, and then a sliding block 303 is slidably arranged on each slide rail 302, and a group of transmission belts 304 are arranged at the left and right ends of the rectangular cover 301, each group of transmission belts 304 is fixedly connected to the sliding block 303 through a connecting block 305, and the two groups of transmission belts 304 are driven by the same motor so that the two groups can run synchronously.
