Detailed Description
As shown in the attached figure 1, the invention comprises a first hopper 5 communicated with a pile foundation hole through a pile foundation conduit 1 and a second hopper 2 suspended above the first hopper 5 through a hoisting device 6, wherein a discharge hole 3 is arranged on the second hopper 2, and materials flowing out of the discharge hole 3 enter the first hopper 5. Preferably, the hoisting device 6 is a truck crane.
In the pile foundation pipe 1 is entered into fast in the convenience of material, first hopper 5 is and leaks hopper-shaped, pile foundation pipe 1 communicates with the bottom of first hopper 5.
The bottom plate 4 of the second hopper 2 is obliquely arranged, the discharge port 3 is positioned at one end of the lower side close to the bottom plate 4, and the oblique bottom plate 4 can ensure that the residual concrete in the second hopper 2 is less and the concrete in the second hopper 2 can completely enter the first hopper.
When the device is used, the second hopper 2 is suspended above the first hopper 5 through the hoisting equipment 6, so that materials in the second hopper 2 can smoothly enter the second hopper 2 through the discharge port 3, sufficient concrete quantity is ensured, and the continuity of first-batch bottom sealing concrete pouring of deep-water diameter pile foundations is ensured.
As shown in fig. 2 and 3, in order to adjust the amount of the material flowing from the second hopper 2 into the first hopper 5, a switch valve is added on the discharge port 3, and in consideration of the severity of the working environment, the switch valve is often damaged in an electric control mode to affect normal use, and the switch valve is in a pure mechanical mode.
The switch valve comprises a supporting plate 7 arranged at the bottom of the second hopper 2 in a sliding mode and an inserting plate 9 connected with one end of the supporting plate 7, the side wall of the second hopper 2 still has a certain length below the bottom plate 4, the supporting plate 7 is arranged on the side wall of the second hopper 2 below the bottom plate 4 in a sliding mode, and the supporting plate 7 can slide up and down in the vertical direction. One side of the supporting plate 7 extends out of the second hopper 2 and is positioned below the discharge port 3, a slot is formed in the discharge port 3, and the inserting plate 9 is inserted into the slot and is moved up and down through the supporting plate 7 to realize the opening and closing of the discharge port 3.
The layer board 7 is located the top of 2 lateral walls of second hopper, under natural state, because the dead weight of layer board 7, layer board 7 is located the position of lower extreme, and the ooff valve is opened, when needs are closed or when reducing the discharge amount, makes 2 downstream of second hopper by lifting device 6, makes the lateral wall of second hopper 2 and layer board 7 contact, drags layer board 7 upward movement, makes picture peg 9 insert the slot gradually in, makes the aperture of discharge gate 3 diminish gradually until closing. When the second hopper 2 needs to be opened again, the second hopper 2 moves upwards, and the supporting plate 7 falls down by self weight and is gradually opened.
As shown in figure 4, in consideration of the situation that the supporting plate 7 cannot be horizontally lifted due to assembly errors in the jacking process, the supporting plate is designed into a telescopic form, when the supporting plate 7 inclines, the length of the supporting plate is increased, the inserting plate 9 is always in a vertical state, the sealing degree between the inserting plate 9 and the inserting groove and the opening and closing difficulty degree are ensured, and the whole switch valve is prevented from being damaged due to the inclination of the supporting plate 7. Thus, the supporting plate 7 is designed into a tubular shape, and comprises a first supporting pipe 701 and a second supporting pipe 702 which are sleeved with each other, connecting plates 704 are arranged inside the first supporting pipe 701 and the second supporting pipe 702, a tension spring 703 is arranged between the two connecting plates 704, and the inserting plate 9 is hinged with the outer side end of the second supporting pipe 702. The side wall of the first hopper 5 is in contact with the first support pipe 701 or the second support pipe 702, and when the pallet 7 is inclined, the extension spring 703 is extended, and the whole pallet 7 is lengthened, and when the level is restored, the pallet returns to the original length by the extension spring 703. It should be noted that the side wall of the first hopper 5 should contact the pallet 7 on the side close to the discharge port 3, but not contact the pallet on the side far from the discharge port 3, so as to prevent the pallet 7 from tilting in the opposite direction and failing to open and close the on-off valve. This work can be by manual observation, by constructor eye-estimation contact position when in actual use to guarantee that the lateral wall of first hopper 5 should contact with the layer board 7 that is close to discharge gate 3 one side.
A connecting cylinder 10 is arranged below the inserting plate 9, a pressure spring 11 is arranged between the bottom of the inserting plate 9 and the bottom of the connecting cylinder 10, and the connecting cylinder 10 is connected with the supporting plate 7. The pressure spring 11 can ensure that a certain buffer effect is achieved when the inserting plate 9 is contacted with the top surface of the discharge hole 3, rigid collision is prevented, and the damage rate of the switch valve is reduced.
The left side and the right side of the inserting plate 9 are respectively provided with a limiting idler wheel 13, the limiting idler wheels 13 are fixed on the second hopper 2 through the mounting plate 12, the limiting idler wheels 13 guarantee that the inserting plate 9 is always in a vertical position and correspond to the slots in the discharging port 3, the opening and the closing of the two discharging ports 3 are smooth, the two discharging ports cannot collide with each other, and the service life can be prolonged. Meanwhile, the inserting plate 9 is hinged with the supporting plate 7 and is matched with the telescopic supporting plate 7, so that the inserting plate 9 moves up and down in the slot more stably and smoothly.
Be provided with a plurality of joint groove 8 on the lateral wall of second hopper 2, the opening part in joint groove 8 is the funnel shaped of invering so that the lateral wall card of second hopper 2 goes into, layer board 7 is located second hopper 2 under, and with joint groove 8 at same height. When the hoist and mount, the lateral wall card of first hopper 5 is gone into the joint inslot 8 of second hopper 2 bottoms in, can guarantee relatively stable between two hoppers, prevents to appear rocking and lead to the concrete to spill the problem in work process second hopper 2. And when preventing to rock, the lateral wall of first hopper 5 also can realize adjusting from top to bottom layer board 7, makes whole equipment operation more stable.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
