DETAILED DESCRIPTION OF THE EMBODIMENTS
[0050] In order to make the technical problems solved, the technical solutions adopted and the technical effects achieved by the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described in further detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are Date Recue/Date Received 2021-07-29 merely a part of the embodiments of the present disclosure, rather than all the embodiments.
Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work shall fall within the protection scope of the present disclosure.
Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work shall fall within the protection scope of the present disclosure.
[0051] As shown in FIGS. 1 to 7, the present embodiment provides a troweling device for troweling a construction surface. The troweling device has a prominent troweling effect, especially on a working surface of concrete in an initial setting stage. The troweling device includes a main body 1, a roller traveling mechanism and a vibrating slurry extracting mechanism 3. The roller traveling mechanism is mounted on the main body 1. The vibrating slurry extracting mechanism 3 is mounted on the main body 1, and is located behind the roller traveling mechanism in a traveling direction of the troweling device. The vibrating slurry extracting mechanism 3 includes a first frame 301 and a vibrating assembly.
The first frame 301 is connected to the main body 1. The vibrating assembly is slidably connected to the first frame 301 in a vertical direction. The vibrating assembly includes a vibrating roller 302 and a vibration motor 303 configured to drive the vibrating roller 302 to vibrate. When the troweling device is working, the roller traveling mechanism drives the whole troweling device to move on the construction surface. On the one hand, the roller traveling mechanism performs preliminary slurry rolling and extracting on slurry on the construction surface; on the other hand, the vibrating roller 302 of the vibrating slurry extracting mechanism 3 abuts against the construction surface under gravity, and the vibration motor 303 drives the vibrating roller 302 to vibrate on the construction surface so as to perform secondary slurry extracting on the slurry on the construction surface. The troweling device according to this embodiment extracts the slurry twice successively in a working stroke, thereby ensuring sufficient floating slurry, improving the slurry extracting effect, and guaranteeing the quality of subsequent troweling.
The first frame 301 is connected to the main body 1. The vibrating assembly is slidably connected to the first frame 301 in a vertical direction. The vibrating assembly includes a vibrating roller 302 and a vibration motor 303 configured to drive the vibrating roller 302 to vibrate. When the troweling device is working, the roller traveling mechanism drives the whole troweling device to move on the construction surface. On the one hand, the roller traveling mechanism performs preliminary slurry rolling and extracting on slurry on the construction surface; on the other hand, the vibrating roller 302 of the vibrating slurry extracting mechanism 3 abuts against the construction surface under gravity, and the vibration motor 303 drives the vibrating roller 302 to vibrate on the construction surface so as to perform secondary slurry extracting on the slurry on the construction surface. The troweling device according to this embodiment extracts the slurry twice successively in a working stroke, thereby ensuring sufficient floating slurry, improving the slurry extracting effect, and guaranteeing the quality of subsequent troweling.
[0052] Further, the vibrating assembly further includes a vibration beam 304. The vibration motor 303 is mounted at a center of the vibration beam 304 in its extending direction through a mounting plate 305. Both ends of the vibration beam 304 are rotatably connected to and correspond to both ends of the vibrating roller 302 respectively. When the troweling device travels for working, the vibrating roller 302 rolls on the construction Date Recue/Date Received 2021-07-29 surface, while the vibration motor 303 mounted on the vibration beam 304 drives itself to vibrate, thus driving the vibrating roller 302 to vibrate together to vibrate the slurry on the construction surface, thereby achieving the slurry extracting effect.
[0053] Certainly, the vibrating roller 302 can also abut against the construction surface driven by a driving member. Specifically, the vibrating slurry extracting mechanism 3 further includes a first linear driving member 306. The first linear driving member 306 is mounted on the first frame 301. An output end of the first linear driving member 306 is connected to the vibration beam 304 in a transmission manner. When the troweling device is in a non-working state or needs to pass over obstacles, the first linear driving member 306 retracts in the vertical direction, driving the vibrating assembly to move vertically upwards. When the troweling device is required to be switched to a working state, the first linear driving member 306 extends in the vertical direction, driving the vibrating assembly to move vertically downwards and abut against the construction surface.
[0054] Preferably, the first linear driving member 306 adopts an electric push rod.
Therefore, the first linear driving member 306 not only has a compact structure, but also has high precision in movement and good self-locking performance. Certainly, in other embodiments, the first linear driving member 306 may also adopt other linear driving members such as air cylinders and oil cylinders and the like.
Therefore, the first linear driving member 306 not only has a compact structure, but also has high precision in movement and good self-locking performance. Certainly, in other embodiments, the first linear driving member 306 may also adopt other linear driving members such as air cylinders and oil cylinders and the like.
[0055] Further, the vibrating slurry extracting mechanism 3 further includes a guide shaft 307 and a linear bearing 308. The guide shaft 307 is provided in the vertical direction, an upper end of which is connected to the output end of the first linear driving member 306 in a transmission manner, and a lower end of which is connected to the vibration beam 304. The linear bearing 308 is fixedly connected to the main body 1. The guide shaft 307 extends through the linear bearing 308. The guide shaft 307 and the linear bearing 308 together provide reliable guidance to move the vibrating assembly up and down.
[0056] Preferably, a vibration isolator 309 is provided between the guide shaft 307 and the vibration beam 304. The vibration isolator 309 is mounted on the vibration beam 304 and connected to the output end of the first linear driving member 306 through a fixing plate 310, to prevent the vibrating assembly from transmitting vibration to the main body 1 along the guide shaft 307. When the vibrating slurry extracting mechanism 3 is working, Date Recue/Date Received 2021-07-29 the vibration isolator 309 can reduce an impact of the vibration generated by the vibration motor 303 on other components of the troweling device except the vibrating assembly, ensuring the overall construction quality.
[0057] Further, two guide shafts 307 are provided in the vibrating slurry extracting mechanism 3. Correspondingly, two linear bearings 308 are provided to match the guide shafts 307 in a one-to-one correspondence. A beam 311 is further horizontally provided between the first linear driving member 306 and the guide shaft 307. A middle portion of the beam 311 is connected to the output end of the first linear driving member 306. Both ends of the beam 311 are respectively connected to the two guide shafts 307.
Specifically, the two sets of guide shafts 307 and linear bearings 308 jointly guide the vibrating assembly to move up and down, such that the moving up and down of the vibrating assembly is more stable, and rotation of the vibrating assembly in a horizontal direction with respect to the first frame 301 is restricted.
Specifically, the two sets of guide shafts 307 and linear bearings 308 jointly guide the vibrating assembly to move up and down, such that the moving up and down of the vibrating assembly is more stable, and rotation of the vibrating assembly in a horizontal direction with respect to the first frame 301 is restricted.
[0058] Furthermore, the troweling device further includes a combing spatula mechanism 4, which is mounted on the main body 1, and is provided behind the vibrating slurry extracting mechanism 3 in the traveling direction of the troweling device. The combing spatula mechanism 4 includes a slurry combing plate 402 and a troweling plate 403. The slurry combing plate 402 is provided with a comb tooth structure extending in a horizontal direction perpendicular to the traveling direction of the troweling device. The troweling plate 403 is provided behind the slurry combing plate 402. A lowest point of the slurry combing plate 402 is located at a position higher than a position where a lowest point of the troweling plate 403 is located. Specifically, after the roller traveling mechanism and the vibrating slurry extracting mechanism 3 have successively performed slurry extracting on the construction surface twice, the slurry combing plate 402 firstly passes through the construction surface subjected to the slurry extracting, and thus the comb tooth structure on the slurry combing plate 402 can effectively smooth the raised slurry on the construction surface. Following closely, the troweling plate 403 passes through the construction surface smoothed by the slurry combing plate 402.
