Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a cast-in-place pile pouring device. Background Art

[0002] During the pouring of concrete for bored piles, a feed conduit is required to feed the concrete into the pile hole. Due to the long length of the pile, the feed conduit cannot be extended to the bottom of the pile at one time. Therefore, most of the feed conduits are made of multiple conduits connected together. On the one hand, it can reduce the manufacturing cost. On the other hand, after pouring a section of concrete, the conduit can be raised and shortened, which makes it more convenient to pour concrete into the pile.

[0003] At present, the connection of this kind of conduit mainly adopts threaded connection or bolted fastening, which will bring the following problems: 1. The threads or bolts on the conduit are easily covered by concrete, and the concrete needs to be cleaned during the disassembly and installation process, which is very inconvenient, and if the concrete is not cleaned clean, it is easy to cause the threads to not work properly; 2. During the pouring process, the disassembly and installation time of the conduit is very long, resulting in the pouring time being extended, which may affect the pouring quality of the pipe pile and the construction period. Therefore, it is necessary to improve the structure of the conduit to reduce the impact of concrete on the installation and disassembly of the conduit and facilitate the rapid installation and disassembly of the conduit. Utility Model Content

[0004] In view of the above problems, the utility model provides a bored pile casting device for reducing the influence of concrete on the installation and disassembly of the conduit, and avoiding the problem that the conduit docking position cannot be installed and disassembled normally due to the presence of concrete, or the installation and disassembly speed is slow.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a cast-in-place pile casting device, including a support base, a support platform is fixedly arranged on the top of the support base, a plurality of mutually docked and fixed conduits are arranged in the middle of the support platform, and a drop hopper is arranged on the top of the conduit;

[0006] The bottom end of the catheter is provided with a first docking plate, on which a plurality of downwardly protruding snap-in pins are arranged; the top end of the catheter is provided with a second docking plate, on which snap-in grooves are arranged for the snap-in pins to be inserted and locked with each other.

[0007] As a further improvement of the above solution, the clamping slot includes an inserting portion and a locking portion, the inserting portion is wider than the locking portion, and the clamping pin is a "T" structure;

[0008] A locking boss is arranged on the lower side of the second docking tray. The locking boss and the lower side of the second docking tray are transitioned by an inclined surface, and the locking portion penetrates the locking boss.

[0009] As a further improvement of the above solution, a plurality of support pins close to the second docking plate are arranged on the outer side surface of the conduit.

[0010] As a further improvement of the above scheme, a clamping block for clamping the catheter is slidably arranged on the support platform, a fixed cylinder is fixedly arranged on the support platform, a movable rod is slidably arranged in the fixed cylinder, and connecting rods are hingedly arranged on the movable rod and are respectively hingedly arranged with the clamping block;

[0011] A bottom plate penetrating the fixed cylinder is fixedly arranged at the bottom of the movable rod, and a spring for pushing the movable rod to move downward is arranged between the bottom plate and the inner cavity of the fixed cylinder.

[0012] As a further improvement of the above solution, a pull rope for pulling the clamping block to both sides is fixedly provided on one side of one clamping block, and a hook is provided on the support platform for hanging the pull rope so that the clamping block loses its clamping force on the catheter.

[0013] As a further improvement of the above solution, a plurality of supporting feet are arranged at the bottom of the drop hopper, and a plurality of limiting pins which can cooperate with the supporting feet are arranged at the top of the support platform.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. By means of the provided bayonet pin and bayonet groove, the two conduits can be fixed by means of the bayonet pin, thus avoiding the problem of low disassembly and assembly efficiency between the two conduits caused by concrete, thereby greatly improving the construction speed. The provided locking boss can increase the connection tightness between the two conduits and avoid falling off.

[0016] 2. The support pins can be used to support the catheters when they are installed and disassembled. At the same time, when the clamping block clamps the catheter, the clamping block supports the support pins, which can support the catheter in the up and down directions to prevent the catheter from falling. Therefore, when installing and disassembling the drop hopper, the catheter can be prevented from falling into the pipe pile. The same structure is used between the catheter and the drop hopper, making installation and disassembly more convenient and quick.

[0017] 3. The spring provided can be used to drive the clamping block to ensure that the clamping block can hold the conduit for a long time to avoid instability of the conduit. In addition, the conduit can be clamped by stepping on the part extending from the bottom plate to avoid shaking of the conduit during pouring. The clamping block can be pulled apart to both sides by the pull rope, making it more convenient to lift the conduit upward.

[0018] 4. The limiting pin can cooperate with the supporting feet to limit the drop hopper and prevent the drop hopper from shaking during the pouring process. BRIEF DESCRIPTION OF THE DRAWINGS
