Description

TECHNICAL FIELD

[0001] The utility model relates to cement suspension roller pipe manufacturing loading technology field more specifically, the utility model relates to cement suspension roller pipe manufacturing loading device. BACKGROUND

[0002] Cement pipe is also called cement pressure pipe, reinforced concrete pipe, and cement suspension roller pipe manufacturing process is a common method for producing cement pipe. Suspension roller pipe manufacturing process is a process in which a suspension roller shaft and a steel mold sleeved on the suspension roller rotate together under the action of friction force driven by a motor. The centrifugal force generated by the rotation of the steel mold makes the concrete mixture manually poured into the steel mold adhere uniformly to the inner wall of the steel mold. As the amount of poured material increases, the thickness of the concrete pipe wall gradually increases. When the thickness of the pipe wall exceeds the die opening, the die opening moves away from the suspension roller. At this time, the concrete in the pipe wall directly contacts the rotating suspension roller. The steel mold continues to rotate relying on the friction force between the suspension roller and the concrete. At the same time, the suspension roller repeatedly rolls the concrete in the pipe wall, so that the concrete reaches the required density and obtains a smooth inner surface in a relatively short time.

[0003] A cement suspension roller pipe manufacturing loading device is disclosed in Chinese patent application No. CN202022656039.2. The device includes a cement device for storing and discharging cement, a loading unit arranged at one end of the discharge pipe for receiving cement from the cement device and placing it into a suspension roller pipe manufacturing machine. The loading unit includes a pair of supports with an arc-shaped discharging plate arranged at the upper end of the support. The bottom end face of the arc-shaped discharging plate is provided with a rack. The loading unit further includes a rotating mechanism with a gear connected to one end of the output shaft of the rotating mechanism. The rack is engaged with the gear. A blocking unit is arranged at the upper end of the loading unit for blocking the material placed in the loading unit into the machine. The device can automatically feed while the suspension roller pipe manufacturing machine is working. The single feeding amount is large, the speed is fast, and the feeding is uniform, which improves the quality of the produced cement pipe and has strong practicality.

[0004] However, as can be seen from the drawings in the specification, the feeding is achieved by inputting water flow onto the discharging plate and inputting the discharging plate into the suspension roller pipe manufacturing machine, and then controlling the discharging plate to reset and repeat the work after discharging. During the feeding process, the discharging plate needs to be controlled to move repeatedly, which affects the feeding efficiency and is not convenient for continuous feeding use, thereby improving the use effect.
