Description

Technical Field

[0001] The utility model relates to the field of troweling machines, and more specifically, to a troweling machine for concrete precast members. Background Art

[0002] When producing concrete precast members, a troweling machine is needed to scrape the end face of the concrete flat, so as to keep the end face of the concrete flat. However, when the existing troweling plate trowels the concrete, it is easily affected by factors such as mortar in the concrete, which may cause the troweling plate to be tilted due to the mortar factor, thereby possibly damaging the transmission shaft and the troweling plate and reducing their service life. For this reason, we propose a troweling machine for concrete precast members. Summary of the Utility Model

[0003] 1. Technical Problems to be Solved

[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a troweling machine for concrete precast members, which limits the troweling plate through an auxiliary plate, thereby preventing the troweling plate from being tilted by mortar, further increasing the service life of the troweling plate and the transmission shaft. At the same time, an auxiliary ring is used to prevent the annular cylinder from sinking into the concrete and facilitate the adjustment of the height of the troweling plate.

[0005] 2. Technical Solutions

[0006] To solve the above problems, the utility model adopts the following technical solutions.

[0007] A troweling machine for concrete precast members includes an annular cylinder. Four symmetrically arranged support plates are installed at the upper end of the annular cylinder. An electric push rod is installed at one end of the four support plates away from the annular cylinder. The output end of the electric push rod is installed with an installation box. A servo motor is installed on the inner wall of the installation box. The output end of the servo motor is installed with a transmission shaft through a coupling. A troweling plate is installed at the lower end of the transmission shaft. Four symmetrically arranged auxiliary plates are installed on the side wall of the installation box. Connecting plates are installed on the side walls of two of the support plates. A rotating rod is installed at the upper end of the connecting plate. The rotating rod is rotatably connected with a push rod.

[0008] Further, an auxiliary ring is installed on the side wall of the annular cylinder. The lower end of the auxiliary ring is set as an arc-shaped end face, which increases the contact surface between the annular cylinder and the auxiliary ring and the concrete, and prevents the annular cylinder from sinking into the concrete.

[0009] Further, a perspective window is opened on the side wall of the annular cylinder, which is convenient for observing the inner cavity of the annular cylinder.

[0010] Furthermore, two docking plates are symmetrically arranged at the upper end of the connecting plate. Rotating rods are installed on the opposite side walls of the two docking plates. One end of the push rod is provided with a docking hole, and the other end of the push rod is installed with a grip ring. The rotating rod is rotatably connected to the docking hole, which facilitates the push rod to push the annular cylinder through the rotating rod and the connecting plate.

[0011] Furthermore, the side wall of the installation box is threadedly connected with an auxiliary door through bolts. Threaded holes adapted to the bolts are provided on both the auxiliary door and the side wall of the installation box, which facilitates the removal of the auxiliary door, thereby facilitating the maintenance of the servo motor inside the installation box.
