Description

Technical Field

[0001] The invention relates to the technical field of concrete floor smoothing, and in particular to a rapid smoothing device for emery concrete floors. Background Art

[0002] The construction of concrete corundum floor mainly includes the following steps: first pouring the concrete base, then smoothing the surface, then spreading corundum, then polishing the surface, then removing the mold and processing the grid joints, and finally doing maintenance. In the smoothing surface treatment stage, the commonly used leveling devices are ride-on, hand-held and laser, among which ride-on and hand-held are more commonly used.

[0003] A hand-held trowel device usually consists of a handrail, a drive device, a trowel disc or a trowel blade. The handrail is used to control the direction, and a switch and control button are installed on it. The drive device can drive the trowel disc to rotate, and then rely on the trowel disc to achieve the smoothing and polishing operations of the surface layer. After the concrete is poured, it is necessary to vibrate it according to common sense. However, since the paving area of ​​the concrete floor is often large, it is difficult to fully carry out the vibration work. Some hand-held trowel devices currently on the market have a vibration structure, but during the leveling process, the intensity is greater near the center of the trowel disc or the location where the vibration source is generated, and the vibration effect is poor at the edge of the trowel disc. The vibration effect is uneven, resulting in poor discharge of bubbles in the concrete. Summary of the invention

[0021] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0022] Reference Figure 1 to Figure 6 , which is the first embodiment of the present invention, provides a rapid leveling device for diamond abrasive concrete floor, including a trowel 100, a driving device 200 and a handrail 300 arranged on the trowel 100, the trowel 100 has a plurality of through holes 400, and also includes: a rotating shaft 501 rotatably arranged on the trowel 100; a swing plate 502 is arranged on the rotating shaft 501, rotates with the rotating shaft 501, the swing plate 502 is located at the through hole 400, and is used to beat concrete after the swing plate 502 swings; a toggle rod 503 is arranged on the rotating shaft 501, and the toggle rod 503 and the rotating shaft 501 rotate with the trowel 100; a limiting rod 504 is fixedly arranged relative to the driving device 200, and after the toggle rod 503 rotates, it abuts against the limiting rod 504 and rotates with the axis of the rotating shaft 501.

[0023] In this embodiment, in order to facilitate the trowel device to achieve the effect of beating the concrete during the troweling process, a plurality of through holes 400 are provided on the trowel plate 100, and the swing plate 502 can swing at the position of the through holes 400. The specific process is: the operator controls the direction of the trowel device through the handrail 300, and the driving device 200 drives the trowel plate 100 to rotate. During the rotation of the trowel plate 100, the toggle rod 503 will collide with the limit rod. Since the trowel plate 100 is still rotating, the toggle rod 503 drives the swing plate 502 to swing toward the direction close to the concrete through the rotating shaft 501. Through the collision between the toggle rod 503 and the limit rod 504, the swing plate 502 achieves the effect of beating, and the swing plate 502 will also vibrate slightly during the collision, that is, the swing plate 502 beats and vibrates the concrete during the swinging process to discharge the bubbles in the concrete. The swinging amplitude of the swing plate 502 is the same, and the beating and vibration effect on the concrete is relatively uniform, and the bubble discharge effect is better.

[0024] Optionally, the driving device 200 includes: a gearbox 700 disposed on the armrest 300, an engine 600 disposed on the gearbox 700, and the gearbox 700 is transmission-connected to the engine 600; an output shaft 800, and both ends of the output shaft 800 are transmission-connected to the wiper plate 100 and the gearbox 700 respectively.

[0025] In this embodiment, the structure of the driving device 200 is described in detail, and a diesel or gasoline engine 600 is used, which is connected to an output shaft 800 through a gearbox 700, thereby driving the wiper 100 to rotate. The use of the engine 600 can avoid the need for long wires and can also adapt to various complex environments.

[0026] Optionally, there are multiple limiting rods 504 , further comprising: a first sleeve 801 is disposed on the gearbox 700 , the output shaft 800 passes through the first sleeve 801 , and the limiting rods 504 are disposed on the first sleeve 801 at circumferential intervals.

[0027] In this embodiment, the first sleeve 801 provides support for the limiting rod 504, and there are multiple limiting rods 504. When the toggle rod 503 rotates with the wiping plate 100, it can collide with multiple limiting rods 504 multiple times, thereby increasing the frequency of the beating and enhancing the beating effect.

[0028] Optionally, it also includes: both ends of the reset member are arranged on the rotating shaft 501 and the wiper plate 100, and the reset member is used to provide a force for resetting the rotating shaft 501; wherein, the spacing between adjacent limit rods 504 is less than or equal to the spacing of the limit rods 504 rotating around the output shaft 800 during the process of rotating from an inclined state to a vertical state.

[0029] In this embodiment, in order to allow the swing plate 502 to reset after hitting the concrete driven by the toggle rod 503, a reset member is provided between the rotating shaft 501 and the wiper plate 100. Preferably, the reset member can be a conventional reset spring. After the swing plate 502 hits the concrete, the reset member drives the swing plate 502 to reset, thereby facilitating the collision of the toggle rod 503 with the limit rod 504. In addition, in order to better utilize the space and reasonably arrange the limit rods 504, after the toggle rod 503 is out of contact with the previous limit rod 504, under the action of the reset member, the toggle rod 503 quickly collides and abuts with the next limit rod 504, thereby forming an uninterrupted beating effect.

[0030] Optionally, it also includes: a second sleeve 802 is rotatably arranged on the output shaft 800; a one-way bearing is located between the second sleeve 802 and the output shaft 800, and the one-way bearing is used to limit the rotation direction of the second sleeve 802; gear 1 803 is arranged on the side of the second sleeve 802 close to the rotating shaft 501, and gear 1 803 is a toothless gear; gear 2 505 is arranged on the rotating shaft 501, gear 1 803 and gear 2 505 are engaged or not engaged, the second sleeve 802 drives the rotating shaft 501 to rotate through gear 1 803 and gear 2 505, and the rotating shaft 501 is used to drive the swing plate 502 to rotate in a direction close to the concrete.

[0031] In this embodiment, two working states are designed for the smoothing device. The first state is: the trowel plate 100 smoothes the concrete. At this time, gear one 803 and gear two 505 are not in a meshing state (that is, the toothless portion of gear one 803 corresponds to gear two 505), and the swing plate 502 will rotate under the action of the toggle rod 503 to achieve the beating of the concrete. The second method is: in the non-working state, by rotating the second sleeve 802, gear one 803 is meshed with gear two 505, and the swing plate 502 is driven to rotate, and the swing plate 502 rotates in the direction toward the concrete, so that the swing plate 502 protrudes from the bottom surface of the wiper plate 100 and the height of the toggle rod 503 is lower than the lowest point of the limit rod 504, and the gear one 803 and the gear two 505 are always kept in meshing state, that is, the swing plate 502 is directly in contact with the concrete, and under the action of the one-way bearing, the second sleeve 802 cannot be reversed, and then the driving device 200 is started, the wiper plate 100 starts to rotate, and the rotation direction is opposite to the rotation direction of the second sleeve 802. Since the swing plate 502 protrudes from the bottom surface of the wiper plate 100, the wiper plate 100 does not contact the concrete. During the rotation, the swing plate 502 directly smoothes the concrete, and the angle of the swing plate 502 can be adjusted by rotating the second sleeve 802. Different working modes can adapt to different working environments. The trowel plate 100 rotates to smoothen the concrete, which can be used for beating the concrete, and can also be used for the first smoothing; the swing plate 502 smoothes the concrete floor to achieve smoothing, which can be used for the second smoothing.

[0032] Optionally, it also includes: a driving rod 900 is rotatably and slidably set on the armrest 300; gear three 901 is set on the side of the driving rod 900 close to the second sleeve 802; gear four 804 is set on the side of the second sleeve 802 close to the driving rod 900, and after the driving rod 900 slides, gear three 901 is engaged or not engaged with gear four 804.

[0033] In this embodiment, in order to facilitate the adjustment of the angle of the swing plate 502, the driving rod 900 drives the gear 3 901 to slide close to the gear 4 804, and the gear 3 901 and the gear 4 804 are meshed, and the driving rod 900 is rotated to drive the second sleeve 802 to rotate, thereby adjusting the angle of the swing plate 502. The trouble of manually adjusting the second sleeve 802 is eliminated, and the operation is convenient. Among them, the gear 3 901 and the gear 4 804 are both helical gears or spiral gears in the prior art. If there are other gears in the prior art that can be implemented, they can also be used.

[0034] Optionally, the armrest 300 includes a support tube 301, and the support tube 301 is used to support the driving device 200. The support tube 301 has a through cavity, and the driving rod 900 passes through the through cavity.

[0035] In this embodiment, in order to arrange the driving rod 900 and the handrail 300 more reasonably, the driving rod 900 directly passes through the support tube 301, so as to reasonably utilize the space and make the overall smoothing device more coordinated.

[0036] Optionally, the support tube 301 has an L-shaped slot 302 on one side close to the second sleeve 802 , and further includes: a clamping rod 902 is arranged on the driving rod 900 , and after the driving rod 900 slides and rotates, the clamping rod 902 enters the L-shaped slot 302 .

[0037] In this embodiment, in order to prevent the gear 3 901 from meshing with the gear 4 804 when the first working state is used, an L-shaped slot 302 is provided on the support tube 301. When the driving rod 900 is not needed to drive the second sleeve 802 to rotate, the clamping rod 902 is located in the L-shaped slot 302, and the gear 3 901 is not meshed with the gear 4 804. When the gear 3 901 and the gear 4 804 need to be meshed, they are rotated first, and then the driving rod 900 is pushed to make the driving rod 900 leave the L-shaped slot 302, and the gear 3 901 and the gear 4 804 are meshed, thereby avoiding interference between the gear 3 901 and the gear 4 804 during the smoothing process.

[0038] Optionally, it also includes: a handle 903 is arranged on the side of the driving rod 900 away from the second sleeve 802 and outside the through cavity.

[0039] In this embodiment, in order to facilitate adjustment, a handle 903 is provided on the driving rod 900 to facilitate the operator to apply force.

[0040] Optionally, it also includes: a protective frame 110 is set on the gearbox 700, and the protective frame 110 is used to protect the wiper plate 100.

[0041] In this embodiment, in order to prevent the operator or other debris from contacting the wiper plate 100 and the output shaft 800 during operation, a protective frame 110 is provided on the gearbox 700 for protection.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
