Description

Technical Field

[0001] This utility model relates to the field of annular concrete pole processing technology, and in particular to a cement pouring and feeding device for producing high-strength annular prestressed poles. Background Technology

[0002] High-strength ring-shaped prestressed poles are ring-shaped columns made of concrete and molds. To enhance the prestress strength at the ends, the concrete pouring molds are pre-embedded with ring-shaped reinforcing bars. Due to their special structural characteristics, they are generally produced using a special cement pouring and feeding device.

[0003] Chinese Patent Publication No. CN117103444B discloses a cement pouring process for producing cement poles, which includes first opening the mold cover and mold core assembly on the left and right sides of the mold base respectively; then inserting several steel bars into the steel bar insertion platform of the mold core cylinder; then fitting the support steel bar assembly into the small diameter end of the mold core cylinder, and using a rotatable rotating ring to engage with several steel bars; starting a servo motor to drive the drive gear ring to rotate, which in turn drives several bevel gears to rotate, thereby driving the vibrating component to swing and vibrate in the cement, thereby eliminating air bubbles;

[0004] The above-mentioned existing technical solutions have the following shortcomings: During the use of this device, since its pouring port is located at the top of the mold cover and the mold is in a slightly inclined horizontal state, the cement needs to be filled in a ring from the top along the outer wall of the mold core during the cement pouring process. In this filling method, since the positions of each pouring port are not easy, as the cement is continuously filled, the air inside the mold is easily squeezed into the cement, which is not conducive to the dissipation of air bubbles. Therefore, there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a cement pouring and feeding device for producing high-strength annular prestressed poles, in order to solve the problems mentioned in the background art, such as the difficulty in quickly filling the mold cavity and the easy mixing of air bubbles into the cement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A cement pouring and feeding device for producing high-strength annular prestressed poles, comprising a base plate, two opposing fixed seats fixed on one side of the top of the base plate, a lower mold shell connected to the top of the fixed seats, an upper mold shell bolted to the top of the lower mold shell, a hollow mold penetrating the interior of both the lower and upper mold shells, a fixed platform fixed on the top of the base plate away from the lower mold shell, two opposing electric telescopic rods fixed on the side of the fixed platform near the lower mold shell, one end of each electric telescopic rod connected to a connecting block, one side of each connecting block connected to the outer side of the hollow mold, the top of the base plate... A support base is fixed at the center, and multiple ball bearings are embedded at the top of the support base. The ball bearings abut against the outer wall of the hollow mold. A cement mixing tank is set on the side of the top of the base plate near the fixed platform. A grouting pump is set at the bottom of the cement mixing tank. The top of the grouting pump is connected to the bottom of the cement mixing tank by a pipe. A hose is connected to the bottom of the grouting pump. One end of the hose is connected to a straight pipe. One end of the straight pipe extends into the interior of the hollow mold. Support rods are evenly fixed on the outer wall of the straight pipe inside the hollow mold. One end of each support rod is fixedly connected to the inner wall of the hollow mold. A discharge mechanism is set at the end of the hollow mold away from the straight pipe. The inner side of the discharge mechanism is connected to one end of the straight pipe.

[0007] Preferably, the lower mold shell and the upper mold shell are the same size, and both ends of the lower mold shell and the upper mold shell are fixed with end caps. The diameter of the through hole formed by the end caps is compatible with the outer diameter of the hollow mold, and the length of the hollow mold is greater than the length of the lower mold shell.

[0008] Preferably, the discharge mechanism includes a rotating head rotatably connected to one end of the hollow mold, the inner end face of the rotating head being connected to one end of a straight tube via a rotating bearing, the outer side wall of the rotating head having multiple discharge ports, and the inner side of the rotating head and the inner wall of the hollow mold being connected to a rotating assembly.

[0009] Preferably, the outer diameter of the rotating head is matched with the outer diameter of the hollow mold, and the discharge ports are distributed in an evenly spaced ring on the rotating head.

[0010] Preferably, the rotating assembly includes an internal gear ring fixed to the inner end face of the rotating head, a rotating motor fixed to the inner wall of the hollow mold, and a gear connected to the output end of the rotating motor, with the outer side of the gear meshing with the inner side of the internal gear ring.

Multiple springs are evenly installed at the bottom of the limiting frame. The tops of the multiple springs are connected to a vibration plate. Multiple vibration rods are fixed at equal intervals at the top of the vibration plate. A vibration motor is provided at the center of the bottom of the vibration plate.

[0012] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0013] 1. The lower and upper mold shells are gradually pushed into the cavity of the hollow mold to cooperate with the discharge mechanism to pour cement into the cavity layer by layer. This filling method helps to expel air bubbles in the cement outward along the unfilled end. At the same time, the rotating component is used to make the rotating head rotate in the cavity, thereby performing ring pouring inside the cavity, which further improves the cement pouring rate and the compactness of the filling.

[0014] 2. The detachable assembly of the lower and upper mold shells allows for demolding of the shaped cement poles. The synchronous activation of the vibration components during the pouring process facilitates the tapping and vibration of the bottom of the lower mold shell, thereby further promoting the compaction of the cement inside the mold cavity and improving the removal of air bubbles.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example 1:

[0027] Combination Figures 1-4 The lower mold shell 3 and the upper mold shell 4 are the same size. Both ends of the lower mold shell 3 and the upper mold shell 4 are fixed with end caps, and the diameter of the through hole formed by the end caps is adapted to the outer diameter of the hollow mold 5. The length of the hollow mold 5 is greater than the length of the lower mold shell 3. The discharge mechanism 14 includes a rotating head 141 rotatably connected to one end of the hollow mold 5. The inner end face of the rotating head 141 is connected to one end of the straight tube 13 through a rotating bearing. The outer side wall of the rotating head 141 has multiple discharge ports 142. A rotating assembly 143 is connected to the inner side of the hollow mold 5 and the inner wall of the rotating head 141; the outer diameter of the rotating head 141 is adapted to the outer diameter of the hollow mold 5, and the discharge port 142 is distributed in an evenly spaced ring on the rotating head 141; 143 includes an internal gear ring 1433 fixed on the inner end face of the rotating head 141, a rotating motor 1431 is fixed on the inner wall of the hollow mold 5, and a gear 1432 is connected to the output end of the rotating motor 1431, and the outer side of the gear 1432 meshes with the inner side of the internal gear ring 1433.

[0028] In this embodiment, the pre-embedded steel bars inside the annular pole are placed inside the lower mold shell 3.
