Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated inspection wells, in particular to a casting device for making prefabricated inspection wells. Background Art

[0002] Prefabricated inspection wells are a common structure in engineering construction and urban infrastructure. They are usually made of concrete, polymer or other materials and are used to manage and maintain underground pipeline systems. The main function of prefabricated inspection wells is to provide a convenient access point so that workers can enter the pipeline system for inspection, cleaning and maintenance.

[0003] For example, the Chinese patent "A casting device for preparing prefabricated inspection wells" with announcement number CN208410181U includes an "I"-shaped frame arranged in the left and right directions, a first conveyor belt and a second conveyor belt, the first conveyor belt is installed on the top of the frame, the second conveyor belt includes a bracket that can be extended and retracted in the left and right directions, conveyor rollers respectively installed on the outer sides of the left and right fixed plates of the bracket and a conveyor belt laid on the conveyor rollers, the two fixed plates and the connecting parts arranged in a scissor structure between the two constitute the bracket, a gear is horizontally arranged above the left end of the bracket, the main shaft of the gear is fixedly connected to the two ends of the fixed plate on the left side through a connecting plate, the other end of the main shaft is rotatably connected to the back side of the right end of the frame, the right end of the frame is fixedly connected to the convex surface of a U-shaped baffle, the top of the baffle is close to the bottom surface of the first conveyor belt, the bottom of the baffle is close to the second conveyor belt, and a discharge trough extends outward from the right end of the second conveyor belt.

[0004] Although the above-mentioned prior art can realize the casting of prefabricated inspection wells, in actual use, on the one hand, the prefabricated inspection wells are not easy to demold after they are completed. After the prefabricated wells are completed, the operator needs to manually knock the steel bars on the concrete to loosen the prefabricated wells, resulting in different manual knocking forces each time, which causes the prefabricated wells to be damaged. On the other hand, it is difficult to evenly fill the mud during the casting process. During the prefabricated well manufacturing process, the mud is directly poured into the mold and the mud automatically fills the mold, resulting in cavities in the mud inside the mold, thereby reducing the quality of the prefabricated wells. Therefore, it does not meet the existing needs. In this regard, we propose a casting device for making prefabricated inspection wells. Utility Model Content

[0005] The utility model aims to provide a casting device for making a prefabricated inspection well, so as to solve the problems in the above-mentioned background technology that the prefabricated inspection well is difficult to demould after being made, and it is difficult to evenly fill the mud during the casting process.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a casting device for making a prefabricated inspection well, comprising a base, support rods are fixedly arranged at the four corners of the upper end of the base, and movable molds are arranged on both sides of the upper end of the base; and also includes:

[0007] A mounting rod, which is arranged between the support rods on both sides and is fixedly connected to the support rods, a first hydraulic telescopic device is fixedly arranged on one side of the mounting rod close to the outer side of the base, and a telescopic end of the first hydraulic telescopic device penetrates and extends to the other side of the mounting rod and is fixedly connected to the movable mold;

[0008] A slide groove is arranged at the upper end of the base, three slide grooves are arranged, and the slide grooves are evenly distributed. Three mounting ear plates are arranged at the lower end of the movable mold, and the mounting ear plates are evenly distributed in a ring shape, and the lower ends of the mounting ear plates extend to the interior of the slide groove.

[0009] Preferably, a fixing rod is fixedly provided inside the mounting ear plate located inside the slide groove, a pulley is provided outside the fixing rod, and the pulley is limited by sliding with the slide groove.

[0010] Preferably, a fixed platform is provided at the upper end of the support rod, and the fixed platform is fixedly connected to the support rod, a second hydraulic telescopic device is fixedly provided at the upper end of the fixed platform, and the telescopic end of the second hydraulic telescopic device passes through and extends to the bottom of the fixed platform, a fixed seat is fixedly provided at the lower end of the telescopic end of the second hydraulic telescopic device located below the fixed platform, and a mounting plate is fixedly provided on one side of the fixed seat.

[0011] Preferably, a telescopic tube is provided at the upper end of the fixed platform on one side of the second hydraulic telescopic device, and the lower end of the telescopic tube extends to the bottom of the fixed platform and is fixedly connected to the mounting plate.

[0012] Preferably, a fixed mold is fixedly provided at the middle position of the upper end of the base, and the positions of the fixed mold and the movable mold correspond.

[0013] Preferably, a vibration chamber is provided at a middle position inside the base, and the vibration chamber is located directly below the fixed mold, and a vibration machine is fixedly provided inside the vibration chamber.

[0014] Preferably, seven threaded holes are provided inside the front and rear ends of the movable mold, and the positions of the threaded holes on the movable molds on both sides correspond.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can move the movable mold through the first hydraulic telescopic device and the pulley. After the prefabricated inspection well is cast, the movable mold is vibrated to loosen the prefabricated inspection well. At this time, the first hydraulic telescopic device is turned on to shrink the telescopic end of the first hydraulic telescopic device. When the telescopic end of the first hydraulic telescopic device shrinks, the movable mold is driven to move while the pulley at the lower end of the movable mold moves in the slide groove, so that the movable mold moves to both sides of the base. At this time, the prefabricated inspection well stays on the fixed mold, and then the operator removes the prefabricated inspection well on the fixed mold, making it easier to remove the prefabricated inspection well, thereby avoiding damage to the prefabricated inspection well during demoulding.

[0017] 2. The utility model can change the height when injecting concrete slurry through the telescopic tube and the second hydraulic telescopic device. During the casting process of the prefabricated inspection well, the movable mold and the fixed mold have been fixed. At this time, the second hydraulic telescopic device is turned on to extend the telescopic end of the second hydraulic telescopic device while driving the telescopic tube to extend and move into the gap between the movable mold and the fixed mold until it moves to a suitable position. Concrete slurry is injected into the gap between the movable mold and the fixed mold through the telescopic tube. After a period of time, the injection of concrete slurry is stopped and the telescopic tube is moved upward for a distance through the second hydraulic telescopic device. At this time, concrete slurry is injected again. The steps of stopping and re-injecting after injection are repeated until the gap between the movable mold and the fixed mold is filled, thereby avoiding the formation of cavities after the concrete slurry is injected at one time, thereby improving the quality of the prefabricated inspection well.

[0018] 3. The utility model is provided with a vibrator, which can make the vibrator generate certain vibrations. When the injection of concrete slurry is stopped, the vibrator is turned on to generate vibrations and transmit them to the movable mold and the fixed mold through the base. At this time, the vibration makes the concrete slurry in the gap between the movable mold and the fixed mold more compact. When the injection of concrete slurry is completed and waiting for demoulding, the vibrator is turned on again. The vibration generated by the vibrator makes the solidified prefabricated inspection well loose on the movable mold and the fixed mold, thereby avoiding damage to the prefabricated inspection well when the operator manually knocks on the mold for demoulding.

When the telescopic end of the first hydraulic telescopic device 5 shrinks, the movable mold 12 is driven to move while the pulley 16 at the lower end of the movable mold 12 moves in the slide groove 14, so that the movable mold 12 moves to both sides of the base 1. At this time, the prefabricated inspection well stays on the fixed mold 13, and the operator removes the prefabricated inspection well on the fixed mold 13.

[0029] See also Figure 1 and Figure 2 The mounting ear plate 15 is located inside the slide groove 14 and is fixed with a fixing rod 17. A pulley 16 is provided outside the fixing rod 17. The pulley 16 and the slide groove 14 are slidably limited, so that the movable mold 12 can move more smoothly through the pulley 16.

[0030] See also Figure 1 and Figure 2 A fixed platform 3 is provided at the upper end of the support rod 2, and the fixed platform 3 is fixedly connected to the support rod 2.

Then, concrete slurry is injected into the gap between the movable mold 12 and the fixed mold 13 through the telescopic tube 7. After a period of time, the concrete slurry is stopped and the telescopic tube 7 is moved upward for a distance through the second hydraulic telescopic device 6. At this time, concrete slurry is injected into the gap between the movable mold 12 and the fixed mold 13. The soil slurry is injected, and the steps of injection, stopping and then injecting are repeated until the gap between the movable mold 12 and the fixed mold 13 is filled. When the injection of concrete slurry is stopped, the vibrator 11 is turned on to make the vibrator 11 vibrate and transmit it to the movable mold 12 and the fixed mold 13 through the base 1.

When the injection of concrete slurry is completed and waiting for demoulding, the vibrator 11 is turned on again. The vibration generated by the vibrator 11 makes the solidified prefabricated inspection well loose on the movable mold 12 and the fixed mold 13.
