[0031] Example

[0032] This embodiment provides a floor smoothing robot, referring to Figure 1As shown, it includes a mobile trolley 1, a swing seat 2, a swing head 3 and a working head. The mobile trolley 1 includes a vehicle body 11 and a walking system 12. The walking system 12 is installed on the vehicle body 11 to drive the vehicle body 11 to move. The walking system 12 is a crawler walking system, which minimizes the damage to the concrete surface during walking and smoothing. The crawler walking system is a conventional technical means in this field. The specific method of achieving walking is not described in detail in this embodiment. The swing seat 2 includes a first shell 21, a swing motor and a secondary swing assembly 22; the swing motor is installed on the vehicle body 11. The first shell 21 is connected to the swing motor, and the swing motor drives the first shell 21 to swing along the horizontal plane. The swing angle of the first shell 21 is ±90°. By driving the swing of the first shell 21, the swing seat 2 is swung, and smoothing operations within the range of ±90° are achieved, thereby increasing the area of ​​single smoothing construction. The secondary swing assembly 22 includes a fixed arm 23, a swing plate 24, and two hydraulic rods 25. The fixed arm 23 is mounted within the first housing 21 and extends outward from one end of the vehicle body 11. The swing plate 24 is hinged to the extended end of the fixed arm 23. The two hydraulic rods 25 are located on either side of the fixed arm 23, with their piston rods abutting against the swing plate 24, driving the swing plate 24 to swing horizontally. When one hydraulic rod 25 is extended, the other is retracted, and the swing plate 24 swings within a ±45° angle. It should be noted that when controlling the swing plate 24 to swing, one of the hydraulic rods 25 is shortened to the shortest position, and then the other hydraulic rod 25 is gradually extended to push the swing plate 24 to rotate around the hinge point between the swing plate 24 and the fixed arm 23, thereby achieving a secondary swing. In order to ensure stability during the swing process, a torsion spring can be installed between the swing plate 24 and the fixed arm 23, so that the torsion spring has a torsion force that drives the swing plate 24 to swing toward the center position. In the process of driving the swing plate 24 to swing, the torsion spring provides a certain reaction force to prevent the swing plate 24 from shaking. The secondary swing of ±45° is achieved on the basis of the swing of the first shell 21. The secondary swing of the swing head 3 can refer to Figure 3 As shown, the single smoothing construction area is further increased, and during the secondary swinging process, smoothing construction can be carried out in the area around the mobile trolley 1, which can avoid missing smoothing operations as much as possible. The swing head 3 includes a second shell 31 and a swing arm 32, and the swing arm 32 is connected to the swing plate 24. The shell is sleeved on the swing arm 32. The swing arm 32 is driven to swing by the swing plate 24. The working head includes a working motor and a smoothing component 4, and the working motor is connected to the swing arm 32. The smoothing component 4 is connected to the working motor, and the smoothing component 4 is driven to rotate by the working motor. The working head is driven to swing by the swing arm 32, thereby realizing smoothing construction over a large area.

[0033] The floor smoothing robot provided in this embodiment can increase the single construction area of ​​the smoothing robot through the first-level swing of the swing seat 2, thereby reducing the number of movements of the smoothing robot and improving construction efficiency; by increasing the second-level swing of the swing plate 24, the single construction area can be further increased, especially the smoothing of the area near the body 11 of the mobile car 1 can be increased, reducing the risk of missed smoothing.

[0034] Specifically, refer to Figure 4 As shown, the smoothing assembly 4 includes a mounting plate 41, a smoothing plate 42, and a vibration system; the mounting plate 41 is connected to a working motor; the smoothing plate 42 is connected to the working motor for vertical relative movement; the vibration system includes a vibration motor 43 and a spring 44; the vibration motor 43 is mounted on the side of the mounting plate 41 facing the smoothing plate 42, and one end of the spring 44 is connected to the mounting plate 41 and the other end is connected to the smoothing plate 42. During the concrete laying process, some undesirable phenomena such as cavities may also occur. By vibrating the smoothing plate 42, the concrete in the cavity position can be sunk, thereby improving the smoothing effect. In addition, since the secondary swinging assembly 22 controls the secondary swinging of the swinging plate 24 by the piston rod and the swinging plate 24, and there is no direct connection, the impact of the vibration generated by the vibration process on the hydraulic cylinder is reduced, thereby improving the overall stability and service life of the smoothing robot.

[0035] Specifically, continue to refer to Figure 4 As shown, a transmission shaft is provided in the middle of the mounting plate 41, and a key 45 is provided on the transmission shaft; an axial hole is provided on the smoothing plate 42, and a key groove 46 is provided on the inner wall of the axial hole; the key 45 is installed in the key groove 46 so as to be movably installed in the vertical direction.

[0036] Specifically, refer to Figure 2 As shown, the piston rod end of the hydraulic rod 25 is rotatably connected to a ball 26; the ball 26 abuts against the swing plate 24. The contact between the ball 26 and the swing plate 24 reduces the resistance between the piston rod and the swing plate 24, thereby facilitating the rotation of the swing plate 24.

[0037] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
