Description

Technical Field

[0001] The invention belongs to the technical field of concrete inspection well pipe feeding, and in particular relates to a concrete inspection well pipe pouring feeding device and a feeding method. Background Art

[0002] Inspection wells are usually composed of well covers, well walls, bottom plates, inlets and outlets. The well covers are the top part of the inspection wells, which play a role in protecting the safety of equipment and personnel in the wells. The well walls are the edges of the inspection wells, which are used to support the well covers and fix the well wall bricks. The bottom plates are the bottom of the inspection wells, which are used to support and fix the well walls. The inlets and outlets are the connecting pipes of the inspection wells, which are used to connect the entry and exit pipes. According to their functions and structures, inspection wells can be divided into four types: straight-through, reverse-arch, lateral and axial. Inspection wells are not only an important part of the pipeline, but also a key facility for pipeline maintenance, inspection and maintenance. During pipeline operation, inspection wells allow engineering and technical personnel to enter the wells at any time to inspect the pipelines, and deal with problems in a timely manner to ensure the smooth operation and safety of the pipelines. The setting and use of inspection wells can ensure the hygiene and environmental quality inside the building. Casting and feeding refers to the process of transporting the mixed concrete materials into the inspection well pipe mold. This is one of the key links in the casting of concrete inspection well pipes, which is directly related to the molding quality and production efficiency of the inspection well pipes.

[0003] In the underground pouring process of concrete inspection well pipes, the method of direct feeding with a conveyor belt needs to adjust the feeding angle. However, deviations are easy to occur when feeding concrete materials, causing concrete materials to spill to surrounding locations, and underground workshops are difficult to clean, affecting the surrounding processing environment and causing waste of concrete materials. In addition, during the preparation and transportation of concrete materials, concrete materials may become hardened due to a slightly longer static time, which may lead to poor feeding and blockage, affecting the continuity and uniformity of feeding. Therefore, it is necessary to provide a concrete inspection well pipe pouring feeding device and feeding method. The integrated design of feeding and turning can ensure the continuity and uniformity of feeding. At the same time, the counter-feeding method can accurately transport materials to the designated location, prevent material waste and pollution of the surrounding environment, and improve feeding efficiency and accuracy.

[0014] A method for pouring and feeding concrete inspection well pipes, wherein the steps of the method are as follows: Step 1: The feeding device is used in the underground pouring process of concrete inspection well pipes. When in use, the conveying frame and the material preparation box are driven to the designated position by the walking frame, and then the second stepper motor is turned on and drives the gear to rotate. Since the gear and the gear ring are in meshing transmission, the gear drives the gear ring and the rotating column to rotate during the rotation process, and the rotating column drives the conveying frame to rotate during the rotation process. The conveying frame rotates 90 degrees, so that the right end of the conveying frame is located at the upper left of the pouring position; Step 2: Next, the first stepper motor is turned on and drives the threaded rod to rotate. During the rotation process, the threaded rod pushes the threaded tube through its surface threads, so that the threaded tube moves to the right and drives the sliding frame to slide to the right, so that the sliding frame and the material guide box reach the top of the casting position. Then the electric telescopic rod is turned on and pushes the sliding block to the right to slide in the inner cavity of the limiting slide groove. During the sliding process, the sliding block drives the top end of the connecting rod to move to the right, so that the bottom end of the connecting rod pushes the lifting tube downward to slide, and then the bottom end of the lifting tube reaches the casting position of the mold. Step 3, then the DC motor starts and drives the two chain disks to rotate. During the rotation of the chain disk, the roller on the left side is driven to rotate. At the same time, with the cooperation of the two rollers, the conveyor belt rotates in the inner cavity of the conveyor frame. During the movement, the conveyor belt drives the concrete material in the inner cavity of the material preparation box to be transported to the right. After the concrete material is transported to the right side of the conveyor frame, the concrete material falls into the inner cavity of the material guide box and the lifting material pipe, and finally reaches the mold. During the transportation of the concrete material, the roller on the left side drives the stirring rod to rotate in the inner cavity of the material preparation box through the cooperation of the two belt pulleys and the belt, and turns the concrete material in the inner cavity of the material preparation box, thereby preventing the concrete material from being compacted in the inner cavity of the material preparation box, ensuring that the concrete material can be discharged and fed evenly and stably, and preventing the occurrence of material blockage; During the movement of the conveyor belt, the spring generates elastic force to push the sliding pin to the right, so that the sliding pin actively pushes the pulley to the right. At the same time, with the coordinated use of the swing arm and the pulley, the rotating rod drives the shovel plate to rotate to the left, so that the top of the shovel plate actively contacts the surface of the conveyor belt, scraping off the concrete material remaining on the surface of the conveyor belt, preventing the remaining concrete material from being driven to the bottom of the conveyor frame, causing pollution to the surrounding environment and waste of materials.

[0015] The beneficial effects of the present invention are as follows: the present invention drives the right end of the conveyor frame to reach the designated casting position through the coordinated use of the walking frame and the direction adjustment component, and then locates the feeding position and guides the material through the coordinated use of the sliding frame and the material guide component, and finally accurately feeds the material through the coordinated use of the material preparation box and the feeding component, thereby achieving the purposes of accurate feeding position, preventing material from contaminating the workshop, and convenient and efficient feeding.

During the movement process, the conveyor belt (41) drives the concrete material located in the inner cavity of the material preparation box (3) to be transported to the right side. After the concrete material is transported to the right side of the conveyor frame (2), the concrete material falls The concrete material is conveyed to the inner cavity of the material guide box (61) and the lifting material pipe (63), and finally reaches the mold. During the process of conveying the concrete material, the roller shaft (42) on the left side drives the stirring rod (45) to rotate in the inner cavity of the material preparation box (3) through the cooperation of two belt pulleys (46) and a belt, thereby turning over the concrete material in the inner cavity of the material preparation box (3), thereby preventing the concrete material from being hardened in the inner cavity of the material preparation box (3), ensuring that the concrete material can be discharged and fed evenly and stably, and preventing the occurrence of material blockage; During the movement of the conveyor belt (41), the spring (77) generates an elastic force to push the sliding pin (75) to the right, so that the sliding pin (75) actively pushes the pulley (76) to the right. At the same time, with the cooperation of the swing arm (73) and the pulley (76), the rotating rod (71) drives the shovel plate (72) to rotate to the left, so that the top of the shovel plate (72) actively contacts the surface of the conveyor belt (41), and the concrete material remaining on the surface of the conveyor belt (41) is scraped off, thereby preventing the remaining concrete material from being driven to the bottom of the conveyor frame (2), causing pollution to the surrounding environment and waste of materials.
