Technical Field
[0001] The utility model belongs to the technical field of troweling machines, and specifically relates to a troweling machine for civil engineering that is easy to move. Background Art
[0002] A troweling machine, also known as a finishing machine, its main structure is a trowel rotor driven by a driving device. Trowels are installed on the bottom surface of the cross on the middle of the rotor. Compared with manual troweling, its troweling efficiency is extremely high, and the input of manpower is reduced. It is an essential mechanical equipment in the civil engineering process.
[0003] The trowel plate of the troweling machine is generally made of stainless steel and has high flatness requirements. However, when the trowel plate is idle, if the edges and corners of the trowel plate are impacted or knocked by external forces, it is very easy to cause the edges of the trowel plate to curl or break, which will affect the flatness of the trowel plate and is not conducive to the normal use of the troweling machine. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a troweling machine for civil engineering that is easy to move, aiming to solve the problems that if the edges and corners of the trowel plate are impacted or knocked by external forces, it is very easy to cause the edges of the trowel plate to curl or break, which will affect the flatness of the trowel plate and is not conducive to the normal use of the troweling machine.
[0005] The utility model is implemented by adopting the following technical scheme:
[0006] A troweling machine for civil engineering that is easy to move includes a connecting frame. A driving device is arranged at the top of the connecting frame. A trowel plate is rotatably connected to the bottom of the connecting frame. The output end of the driving device passes through the connecting frame and is fixedly connected to the trowel plate. The trowel plate is provided with a protection device for protecting the edge. The protection device includes a circular ring. The circular ring is sleeved on the outer edge of the trowel plate. The circular ring is connected to the connecting frame through a bracket. The bracket can adjust the up and down movement of the circular ring.
[0007] When the troweling machine is not in use, the circular ring is sleeved on the outer edge of the trowel plate, and the circular ring completely covers the edge of the trowel plate to protect the edge of the trowel plate, which is beneficial to preventing the edge of the trowel plate from curling or breaking due to direct impact of external forces on the edge of the trowel plate, and ensuring the flatness of the trowel plate. When using the troweling machine, the circular ring is adjusted to move in the vertical direction through the bracket, and the circular ring is raised to a height that does not affect the operation of the trowel plate, and then the troweling machine is turned on to start working.
[0008] Further preferably, the two brackets are symmetrically arranged at the top of the ring. A through hole is arranged on the side of the bracket close to the connecting frame. A threaded rod passes through the through hole. A threaded hole block is threadedly connected to the outer surface of the upper side of the bracket of the threaded rod. One side of the two threaded hole blocks is fixedly connected to the connecting frame. When using the troweling machine, rotate the two threaded rods simultaneously. The threaded rods will move up and down in the threaded hole blocks. During the movement of the threaded rods, the ring connected to the bracket will be driven to move in the vertical direction until the ring completely covers the edge of the trowel disc, so that the edge of the trowel disc can be protected.
[0009] Further preferably, a bearing is arranged in the through hole. The threaded rod is assembled with the inner ring of the bearing, and the inner wall of the through hole is assembled with the outer ring of the bearing. By arranging the bearing, the friction between the threaded rod and the bracket can be reduced when rotating the threaded rod, making it more labor-saving when rotating the threaded rod.
[0010] Further preferably, one end of the threaded rod is provided with an operating block. The operating block is located above the threaded hole block, and protrusions are arranged on the outer surface of the operating block. By arranging the operating block, rotating the operating block can drive the threaded rod to rotate. At the same time, protrusions are arranged on the outer surface of the operating block, which can effectively increase the friction on the outer surface of the operating block and play an anti-slip role when rotating the operating block.
[0011] Further preferably, a limiting rod is fixedly connected to the bottom of the threaded hole block. A limiting blind hole is arranged at the corresponding position of the bracket. The limiting rod can be inserted into the limiting blind hole to limit the limiting rod. The height after the limiting rod is inserted into the limiting blind hole is the minimum distance that the threaded hole block and the bracket can approach.
[0012] Further preferably, round hole blocks are symmetrically arranged on both sides of each bracket connected to the ring. A threaded pin is inserted into the inner wall of the round hole of the round hole block. One end of the threaded pin is threadedly connected to the top of the ring, and a nut is arranged on the outer surface of the other end of the threaded pin. The nut is screwed above the round hole block. Rotate the nut so that one side of the nut abuts against one side of the round hole block, then the ring and the bracket can be connected, and at the same time, it is also convenient for the ring to be disassembled, maintained and replaced.
[0013] Further preferably, a telescopic adjusting device is fixedly connected to one side of the connecting frame. The adjusting device includes a cylinder. A round rod is slidably connected to the inner wall of the cylinder. One end of the round rod is rotatably connected to one side of the connecting frame, and the other end is fixedly connected to a handrail. A threaded hole is arranged on the circumferential surface of the cylinder, and a threaded ejector rod is inserted into the inner wall of the threaded hole. By arranging the threaded ejector rod and pushing the round rod to slide on the inner wall of the cylinder, the length of the round rod can be adjusted correspondingly according to the actual needs of the operator. At the same time, rotate the threaded ejector rod so that one end of the threaded ejector rod abuts against the outer surface of the round rod, then the round rod and the cylinder can be fixed.
[0014] Further preferably, one end of the threaded mandrel is fixedly connected to a rotating block, one side of the rotating block is fixedly connected to an elastic rope, and one end of the elastic rope is fixedly connected to the outer surface of the cylinder. By providing the elastic rope, the rotating block and the cylinder can be connected, which is helpful to prevent the threaded mandrel from being lost after being separated from the inner wall of the cylinder.
[0015] Further preferably, the other end of the threaded push rod is fixedly connected to a rubber block, and the outer surface of the rubber block abuts against the outer surface of the round rod. By providing the rubber block, one end of the threaded push rod can be replaced to abut against the outer surface of the round rod, thereby increasing the friction between the threaded push rod and the round rod, making the fixation between the round rod and the cylinder more stable.
[0016] In the utility model, by setting a circular ring, under the action of the threaded rod, the threaded rod can drive the circular ring connected to the bracket to move in the vertical direction until the circular ring completely covers the edge of the wipe plate, so that the edge of the wipe plate can be protected, which is beneficial to prevent external force from directly hitting the edge of the wipe plate and causing the edge of the wipe plate to warp or be damaged, thereby ensuring the flatness of the wipe plate.
