Description

Technical Field

[0001] The utility model relates to the technical field of integral precast culvert production, in particular to an integral precast culvert production system that saves space. Background Technique

[0002] At present, the production of integral precast culverts mainly adopts the fixed pedestal method. The fixed pedestal method is a relatively traditional production method. During curing, a tarpaulin is also used to cover and steam is introduced. Moreover, the space occupied by steam is large and the efficiency is low. Manual operation of lifting equipment is mostly used for transportation and transfer between various processes, and the coherence and automation degree between each process are low. A continuous automated production line cannot be formed between the various processes of casting production and between casting and curing. Content of the Utility Model

[0003] The utility model aims to provide an integral precast culvert production system that saves space and forms a closed-loop cyclic continuous production, and solves the problems that the existing curing by tarpaulin occupies a large space and each process cannot be streamlined.

[0004] To achieve the above-mentioned utility model purpose, the present utility model adopts the following technology: an integral precast culvert production system that saves space, including a pouring production line. The pouring production line includes a demolding station, a mold cleaning station, a steel cage placing station, a mold closing station, a pouring and vibrating station, a static stop station, and a finishing station arranged in sequence along a straight line direction. It is characterized in that it further includes a steam curing cellar. There are two rows of steam curing cellars distributed vertically. The distribution direction of the steam curing cellars in the same row is the same as the direction of the pouring production line. One row of the steam curing cellars is located underground. There is a mold transfer trolley running track in front of each row of steam curing cellars. A mold transfer trolley is arranged on the mold transfer trolley running track. The two ends of the pouring production line and the two ends of the two rows of steam curing cellars are connected through a track installation trench. A mold transfer mother trolley running track is arranged in the track installation trench. A mold transfer mother trolley is connected through a lifting device on the mold transfer mother trolley running track. During use, the integral precast culvert made at the finishing station together with the integral precast culvert mold is transferred to the mold transfer mother trolley at the feeding end, and then it travels on the mold transfer mother trolley running track to the side of the mold transfer trolley running track. If the integral precast culvert needs to be sent into the upper row of steam curing cellars, the height is adjusted through the lifting device so that the mold transfer mother trolley is aligned with the mold transfer trolley on the upper mold transfer trolley running track. If the integral precast culvert needs to be sent into the lower row of steam curing cellars, the height is adjusted through the lifting device so that the mold transfer mother trolley is aligned with the mold transfer trolley on the lower mold transfer trolley running track. The integral precast culvert and the integral precast culvert mold are transferred to the mold transfer trolley. The mold transfer trolley runs to the front of the corresponding steam curing cellar, and the integral precast culvert and the integral precast culvert mold are transferred from the mold transfer trolley to the steam curing cellar for curing. The cured integral precast culvert together with the integral precast culvert mold is transferred to the mold transfer mother trolley on the mold transfer mother trolley running track at the discharging end through the mold transfer trolley. The mold transfer mother trolley transfers the integral precast culvert and the integral precast culvert mold to the demolding station. After demolding at the demolding station, the finished integral precast culvert is taken away, and the integral precast culvert mold undergoes the above cycle to produce the next integral precast culvert. In this technical solution, there are two rows of steam curing cellars arranged vertically and one row is underground, which can save the above-ground space.

[0005] Preferably, the steam curing cellar has a cellar opening only at one end of the mold transfer trolley running track. This can improve the airtightness to enhance the curing effect.

[0006] Preferably, the lifting device includes a base slidably connected to the running track of the mother mold-carrying trolley, a bracket for supporting the mother mold-carrying trolley, and a plurality of cross members that are distributed in the vertical direction and are hinged together in the middle by a cross member hinge shaft. The two rods of two adjacent cross members are hinged together. The upper ends of the two rods of the cross member at the uppermost position are slidably connected to the bracket, and the lower ends of the two rods of the cross member at the lowermost position are slidably connected to the base. The lower ends of the two rods of the cross member at the lowermost position are connected together by a telescopic oil cylinder. The telescopic direction of the telescopic oil cylinder is perpendicular to the cross member hinge shaft, and both the telescopic direction of the telescopic oil cylinder and the extending direction of the cross member hinge shaft are horizontal. During use, the lifting is achieved by the telescopic movement of the telescopic oil cylinder.

[0007] Preferably, the sub mold-carrying trolley includes a frame supported on the running track of the sub mold-carrying trolley by support rollers and a panel connected to the frame. A plurality of support balls are spherically hinged on the panel. A support roller is rotatably connected in the steam curing cellar and extends along the extending direction of the running track of the sub mold-carrying trolley. The support rollers are distributed perpendicular to the extending direction of the running track of the sub mold-carrying trolley. A precast box inlet / outlet mechanism is provided on the sub mold-carrying trolley to move the integral precast box from the sub mold-carrying trolley into the steam curing cellar and take it out of the steam curing cellar onto the sub mold-carrying trolley.

[0008] Preferably, the precast box inlet / outlet mechanism includes a driving ring with an opening in the vertical direction at one end of the integral precast box located at the kiln mouth of the steam curing cellar, a telescopic rod whose lower end is hinged to the side of the sub mold-carrying trolley away from the steam curing cellar by a first lower hinge shaft, and a driving mechanism for driving the telescopic rod to swing with the lower hinge shaft as the axis. The first lower hinge shaft extends along the extending direction of the running track of the sub mold-carrying trolley. The upper end of the telescopic rod is used to extend into the driving ring. The process of moving the integral precast box culvert into the steam curing cellar is as follows: The driving mechanism drives the telescopic rod to swing towards the steam curing cellar to push the integral precast box culvert so that the integral precast box culvert together with the integral precast box culvert mold enters the steam curing cellar, and the swing drives the integral precast box culvert to translate for steam curing in the cellar. The process of moving the integral precast box culvert out of the steam curing cellar is as follows: The upper end of the telescopic rod is inserted into the driving ring, and then the driving mechanism drives the telescopic rod to swing away from the steam curing cellar to pull the driving ring so that the integral precast box culvert together with the integral precast box culvert mold is taken out of the steam curing cellar. During the swinging process, the telescopic rod simultaneously expands and contracts to maintain in the driving ring and does not touch the top wall of the steam curing cellar. A specific structure for entering and exiting the steam curing cellar is provided.

[0009] Preferably, the driving mechanism includes a cylinder whose lower end is hinged to the sub mold-carrying trolley by a second lower hinge shaft, and the upper end of the cylinder is hinged to the lower end of the telescopic rod by an upper hinge shaft. The second lower hinge shaft, the first lower hinge shaft, and the upper hinge shaft are parallel to each other.

[0010] Preferably, the telescopic rod is a cylinder with at least two strokes, which can make the extension time longer and the contraction time shorter.
