[0003] As a kind of prefabricated pile, the wall thickness of the expanded head end of the expanded head pile is super thick, the concrete volume ratio reaches more than 80%, there are gaps and moisture before the concrete is formed, and the bulk density is low. In addition, in the existing pumping process production process, after the materials are laid out according to the requirements and the expanded head tail end is almost completely filled with concrete materials, when the pumping pipe is pulled out, part of the concrete material leaks out from the injection hole of the fixed plate, resulting in insufficient wall thickness of the prefabricated pile after centrifugal forming. Therefore, in order to ensure that the concrete capacity at the end meets the use requirements and eliminate the phenomenon of insufficient wall thickness, it is necessary to fill in the same amount of the missed concrete material.

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0021] like Figure 1 , 2 As shown, the utility model provides a feeding device for the end of an expanded head pile, including a support column 1, and a hopper 2 for storing concrete material and a lifting assembly 3 for driving the hopper 2 to rise and fall are connected to the support column 1, and an opening and closing assembly 4 for controlling the opening or closing of the discharge port is connected to the discharge end of the hopper 2; a chute 5 is also provided on the support column 1, and the feed port of the chute 5 corresponds to the discharge port of the hopper 2, and the discharge port of the chute 5 corresponds to the feeding hole preset at the upper end of the expanded head part of the expanded head pile mold 11. In this embodiment, the opening and closing assembly 4 directly selects a mature valve structure, specifically a DN200 pneumatic butterfly valve, which has a simple structure and is easy to operate. In addition, in this structure, the overall structure of the hopper 2 is funnel-shaped, that is, the upper opening is large, and the lower discharge port gradually shrinks, which is convenient for the automatic falling of concrete materials.
[0022] In the above structure, after the pile body of the expanded head pile is pumped and distributed, a special rubber plug is sealed on the distribution port of the mold 11, and then the mold 11 is transferred as a whole to the feeding position to ensure that the preset feeding hole on the mold 11 corresponds to the discharge port position of the chute 5; then the lifting component 3 is operated to drive the hopper 2 to descend to the set height, and the concrete material is added to the hopper 2, and the lifting component 3 is continued to be operated to drive the hopper 2 to rise to a position where its discharge port is slightly higher than the upper end surface of the chute 5, and the opening and closing component 4 is opened, and the concrete material in the hopper 2 enters the chute 5, and then is poured into the mold 11 from the discharge port of the chute 5 until the material feeding at the tail end of the mold 11 meets the target requirements, and finally the feeding hole is blocked, and the entire feeding process is completed.
[0023] Of course, in other embodiments, the support column 1 can also be set as a movable structure, so that when adding material, the support column 1 can be moved to ensure that the outlet of the hopper 5 corresponds to the feeding port on the mold 11 without moving the mold 11.
[0024] In this embodiment, in order to facilitate the plugging of the feeding hole on the mold 11, a sealing nut is provided at a position corresponding to the feeding port on the mold 11. A sealing screw is provided at one end of the sealing nut to match the thread of the feeding hole, and an external hexagonal screw head is provided at the other end to match with a special wrench for operation and rotation. When feeding, the sealing screw is opened, and after the feeding is completed, the sealing screw is tightened, which has both boundary and good sealing performance, thereby reducing the risk of concrete leakage.
[0025] In addition, the lifting component 3 in the above structure is preferably an electric hoist, and a suspension rope is connected to the upper side wall of the hopper 2, and the hopper 2 is suspended on the hook of the electric hoist through the suspension rope; the hoist structure is easy to operate and occupies little space.
[0026] In this embodiment, a hoist beam 6 is horizontally arranged and used to drive the electric hoist to move horizontally. After this arrangement, the electric hoist can not only realize the lifting and lowering of the funnel but also move it horizontally, further ensuring that the position of the discharge port of the hopper 2 after the hopper 2 is lifted accurately corresponds to the position of the feed port of the chute 5.
[0027] Of course, in other embodiments, a manual hoist can also be used to drive the lifting of the hopper, and there is no need to use a hoist to lift the beam 6. During operation, when the hopper filled with concrete material is lifted to a set height, if the discharge port of the hopper is not aligned with the feed port of the chute 5, the hopper can be manually pulled to adjust the horizontal direction until the discharge port position of the hopper 2 is aligned with the feed port position of the chute 5.
[0028] In this embodiment, a horizontally arranged support arm 7 is connected to the outer wall of the chute 5, and the end of the support arm 7 away from the chute 5 is rotatably connected to the outer wall of the support frame, so that the chute 5 can rotate around the support column 1; specifically, the chute 5 can be rotated to the feeding position to add the concrete material in the funnel to the feeding hole of the mold 11; it can also be rotated to the storage position in the direction away from the mold 11, and in the storage state, the protruding chute 5 will not affect the normal work of the workers; in this structure, the chute 5 can be flexibly switched between the feeding position and the storage position to ensure the convenience of feeding and other work.
[0029] More specifically, in the chute 5 structure of this embodiment, a fixed plate 8 is connected to the end of the support arm 7 away from the chute 5, and the fixed plate 8 and the support arm 7 can rotate relative to each other in the horizontal direction. The specific rotational connection is through a hinge; the fixed plate 8 is detachably connected to the outer wall of the support column 1 by connecting screws.
[0030] In addition, such as Figure 2As shown, in this embodiment, a vertically extending slide groove 9 is provided on the outer wall of the support column 1, and the fixed plate 8 is vertically slidably connected in the slide groove 9; the fixed plate 8 can slide up and down in the slide groove 9 to adjust the height position of the chute 5, so that the discharge port of the chute 5 can better cooperate with the feeding port on the mold 11, preventing the concrete material from spilling on the ground and causing waste. More specifically, two positioning plates 10 with L-shaped cross sections are symmetrically connected on the outer wall of the support column 1, and the ends of the vertical plates of the two positioning plates 10 away from the horizontal plates are directly welded to the outer wall of the support column 1, and the horizontal plates of the two positioning plates 10 are close to each other, forming a slide groove 9 structure between the two positioning plates 10, and a plurality of fastening screws arranged vertically are provided on the horizontal plates of the two positioning plates 10, and correspondingly, threaded holes for fastening screws are provided on both sides of the fixed plate 8.
[0031] In other embodiments, the chute 5 may not be designed to be a structure that can slide up and down, but in order to ensure that the concrete material in the discharge port of the chute 5 can be accurately added to the feeding hole of the mold 11, the worker can hold a feeding hopper 2 during operation, insert the lower end of the feeding hopper 2 into the feeding hole, and the upper end of the feeding hopper 2 corresponds to the discharge port of the chute 5.
[0032] In this embodiment, preferably, the support column 1 is a workshop column, and the ready-made columns in the workshop are directly used as the support column 1, which reasonably utilizes the existing structure and does not need to add additional support columns 1, thereby simplifying the workshop structure and reducing costs.
[0033] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
