Description

Technical Field

[0001] The utility model relates to the technical field of bottom mold clamping devices, in particular to a bottom mold clamping device for a concrete pipe pile. Background Art

[0002] When producing concrete pipe piles, it is necessary to go through the processes of feeding, tensioning, centrifugation, steam curing at room temperature, tensioning, demoulding and high-pressure steam curing. Pipe pile molds are usually divided into two types: open mode molds and non-open mode molds. When demoulding the pipe piles, the open mode molds need to be separated in half to separate the top mold and the bottom mold, so that the pipe piles cast inside the mold can be easily taken out. Usually, in the process of manual mold opening, it is necessary to manually fix the mold with equipment such as fixing hooks, and then use a crane to lift the top mold for mold opening. However, in the automated pipe pile production line, the transportation of molds is mostly automatic using chain machines. , and then use a overhead crane or automatically for demoulding. In order to ensure the smooth operation of the entire process, the demoulding steps of the automated production line are generally set on the chain machine for direct demoulding, which is convenient for directly moving the bottom mold and pipe piles for subsequent demoulding, discharging and cleaning; However, this process of demoulding directly on the chain machine will cause the overhead crane to directly lift the bottom mold together because the top mold and the bottom mold are too tightly bonded, causing the mold to derail from the chain machine, thereby blocking the production line. If a special fixed tooling is used, it is necessary to use a translation cart to move the pipe piles to the fixed tooling for demoulding, and then move them back to the chain machine, which makes the steps very cumbersome.

[0003] After searching, the prior art disclosed (Announcement No.: CN220129098U) a bottom mold clamping device for a concrete pipe pile electric pole production line, which records that "the grab hook is connected to the linkage transfer mechanism through axial fixation, the shaft pins on both sides of the linkage transfer mechanism are connected to the ear plate frame, the bottom of the linkage transfer mechanism is connected to the pull rod of the cylinder, the cylinder is vertically connected to the ear plate frame, the bottom of the ear plate frame is connected to the adjustment base through bolts, the two sides of the adjustment base are connected to the ear plate frame through waist-shaped holes, and the linkage transfer mechanism includes a push block, a linkage arm and a rotating shaft."; This device can be used after the pipe pile is demoulded. When hanging the product, the bottom mold is clamped and pulled to prevent the bottom mold from being lifted along with the product due to the adhesion between the pipe pile and the pipe mold. In addition, due to the narrow size of the device, it can be set on both sides or in the middle of the chain machine to facilitate the setting of the production line. However, in actual use of the device, the spacing of the coaxial grab hooks cannot be easily adjusted, and then the bottom molds of different sizes cannot be easily grasped, affecting the demolding efficiency of the concrete pipe piles. At the same time, the adjustment base and the ear plate frame of the device are fixed only by the friction force formed by the extrusion of the bolts. Therefore, during long-term use, relative movement is likely to occur between the adjustment base and the ear plate frame, which affects the subsequent clamping effect of the bottom mold.
