Description

Technical Field

[0001] The utility model relates to the technical field of ground maintenance, and particularly relates to a ground leveling and vibrating mechanism. Background Technique

[0002] The main purpose of concrete leveling is to ensure the flatness and beauty of the ground, which helps to evenly disperse the load, reduce the risk of cracking, facilitate subsequent construction and maintenance, and at the same time promote the hydration reaction of cement, improving the overall project quality and service effect. However, through the ground maintenance work after concrete leveling, the evaporation of water on the concrete surface can be reduced;

[0003] For the traditional ground maintenance work after concrete leveling, it is mainly manual film covering for moisture preservation or using a disc compactor for grinding to ensure that the concrete ground does not have quality problems such as cracking due to water shortage;

[0004] The traditional ground maintenance work after concrete leveling has the following problems: Manual film covering will not only damage the already leveled working surface, but also requires two people to work simultaneously. The entire construction process is time-consuming and laborious, with high construction costs and low work efficiency. Therefore, we propose a ground leveling and vibrating mechanism. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects, provide a ground leveling and vibrating mechanism, solve the problems of manual film covering and secondary damage to the concrete leveled ground, greatly improve the operation efficiency of the leveling work, reduce the on-site construction personnel requirements and construction costs, and can effectively solve the problems in the background technique.

[0010] Further, it also includes a laser receiver, which is arranged at the top of the control box. The laser receiver is bidirectionally electrically connected to the control box, facilitating the control of internal electrical appliances.

[0011] Further, it also includes a leveling frame, which is respectively fixedly connected to the left and right ends of the cross beam. The top ends of the leveling frames are respectively rotationally connected to the telescopic ends of the second electric push rods through pin shafts. The input ends of the second electric push rods are electrically connected to the output end of the control box, realizing the leveling function of the wet concrete ground.

[0012] Further, the automatic film covering mechanism includes a linear bearing, a tool rest, a support rod, a cutting platform, a film roll and a cutter. The cutting platform is fixedly connected to the front end of the clamping mechanism. The left and right ends of the upper surface of the cutting platform are respectively fixedly connected with support rods. The upper ends of the support rods are respectively slidably connected to the left and right ends of a tool rest through linear bearings. The cutter is installed on the front side of the tool rest through bolts. The film roll is rotationally connected between the left and right inner walls of the cutting platform.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present ground leveling and vibrating mechanism has the following advantages:

[0017] During the process of the four-wheel differential chassis moving backward for leveling, the film roll is evenly spread on the leveled concrete surface along with the chassis.

[0022] Please refer to Figure 1-2 , this embodiment provides a technical solution: a ground leveling and vibrating mechanism, including a four-wheel differential chassis 1 and a clamping mechanism 12;

It also includes a leveling frame 6. The leveling frame 6 is fixedly connected to the left and right ends of the cross beam 7 respectively. The top ends of the leveling frame 6 are rotatably connected to electric push rods 5 through pin shafts. The telescopic ends of the electric push rods 5 are fixedly connected to the top ends of a laser leveling scraper 11 respectively. The input ends of the electric push rods 5 are electrically connected to the output end of the control box 3. In an area outside the construction site, find a position with good visibility and set up a laser transmitter. According to the on-site elevation line, confirm the horizontal elevation of the leveling machine robot. The robot is manually confirmed by the operator and manually selected into the building area to be leveled according to the map built by BIM. The robot controller automatically performs path planning according to the actual situation of the map, controls the operation of the electric push rod 4. The telescopic end of the electric push rod 4 drives the cross beam 7 to lift. The cross beam 7 drives the laser leveling scraper 11, the vibrating plate 10 and the automatic film covering mechanism 8 at its tail to lift, so that the whole machine moves forward along the planned path until it reaches the starting position of the construction. Then, the laser receiver 2 receives the laser signal from the external laser transmitter and feeds it back to the robot controller in the control box 3. Then, the operation of the electric push rod 5 is controlled. The telescopic ends of the electric push rods 5 respectively drive the left and right ends of the laser leveling scraper 11 to achieve the leveling function of the wet concrete ground;

[0024] Clamping mechanism 12: It is respectively arranged at the left and right ends of the cross beam 7. An automatic film covering mechanism 8 is provided at the front end of the clamping mechanism 12. A vibrating plate 10 is provided at the bottom end of the automatic film covering mechanism 8. The automatic film covering mechanism 8 includes a linear bearing 81, a tool rest 82, a support rod 83, a cutting platform 84, a film roll 85 and a cutter 87. The cutting platform 84 is fixedly connected to the front end of the clamping mechanism 12. The bottom end of the cutting platform 84 is fixedly connected to the top end of the vibrating plate 10. The vibrating plate 10 vibrates at a specific angle to ensure the compactness of the concrete. Support rods 83 are respectively fixedly connected to the left and right ends of the upper surface of the cutting platform 84. The upper ends of the support rods 83 are respectively slidably connected to the left and right ends of a tool rest 82 through linear bearings 81. A cutter 87 is installed on the front side of the tool rest 82 by bolts. The film roll 85 is rotatably connected between the left and right inner walls of the cutting platform 84. The film roll 85 is cooperatively installed with the cutter 87. Uniformly distributed sawteeth are provided on the blade at the bottom end of the cutter 87. It also includes a pressing mechanism 9. The pressing mechanism 9 includes a pressing plate 91 and a polyurethane pressing strip 92. The number of pressing plates 91 is three. The three pressing plates 91 are respectively fixedly connected to the upper end of the tool rest 82. Polyurethane pressing strips 92 are provided on the front and rear sides of the bottom end of each pressing plate 91. The automatic film covering mechanism 8 also includes an electric push rod three 86 and a frame 88. The frame 88 is welded to the rear end of the upper surface of the cutting platform 84. The front end of the frame 88 is rotatably connected to the electric push rod three 86 through a pin shaft. The telescopic end of the electric push rod three 86 is fixedly connected to the top end of the middle pressing plate 91. The input end of the electric push rod three 86 is electrically connected to the output end of the control box 3. While the four-wheel differential chassis 1 moves backward for leveling, due to the adsorption force of the wet concrete ground, the wound film roll 85 is evenly spread on the leveled finished surface along with the moving speed of the four-wheel differential chassis 1. When, according to the planned path, the leveling work reaches the end point position, the electric push rod three 86 receives a specific instruction from the robot controller. The telescopic end of the electric push rod three 86 pushes the pressing plate 91, so that the tool rest 82 moves vertically in a straight line along the support rod 83 through the linear bearing 81 until the polyurethane pressing strip 92 contacts the cutter 87 respectively, driving the toothed cutter 87 to cut the film roll 85. After cutting, it automatically rises under the control of the robot controller, so that the film can be automatically covered on the leveled concrete surface while the construction operation is in progress, solving the problems of manual film covering and secondary damage to the leveled concrete ground, greatly improving the operation efficiency of the leveling completion, reducing the on-site construction personnel requirements and construction costs. Driven by the four-wheel differential chassis 1, starting from the leveling starting position, along with synchronous ground leveling, vibrating and slurry lifting, and automatic film covering operations, under the differential control of the chassis, the robot realizes the corresponding steering movement until it reaches the adjacent position to be leveled. During the whole operation process, the film covering mechanism at the tail continuously outputs the film and always adheres to the ground for automatic film covering, achieving the requirement of synchronously completing leveling and film covering for the ground after the leveling construction is completed;

[0025] Among them: The input end of the control box 3 is electrically connected to an external power supply, and the output end of the control box 3 is electrically connected to the input end of the first electric push rod 4.

[0026] The working principle of a ground leveling and vibrating mechanism provided by the present utility model is as follows: In an area outside the construction site, find a position with good visibility, set up a laser transmitter, and confirm the horizontal elevation of the leveling machine robot according to the on-site elevation line. The robot is manually confirmed and manually selected into the building area to be leveled and constructed according to the map built by BIM. The robot controller automatically conducts path planning according to the actual situation of the map, controls the operation of the first electric push rod 4, and the telescopic end of the first electric push rod 4 drives the cross beam 7 to lift. The cross beam 7 drives the laser leveling scraper 11, the vibrating plate 10, and the automatic film covering mechanism 8 at its tail to lift, so that the whole machine moves forward along the planned path until it reaches the starting position of construction. Then, the laser receiver 2 receives the laser signal from the external laser transmitter and feeds it back to the robot controller in the control box 3, and then controls the operation of the second electric push rod 5. The telescopic ends of the second electric push rod 5 respectively drive the left and right ends of the laser leveling scraper 11 to achieve the leveling function of the wet concrete ground. At the same time, the vibrating plate 10 vibrates at a specific angle to ensure the density of the concrete. While the four-wheel differential chassis 1 moves backward for leveling, the adsorption force of the wet concrete ground causes the wound film roll 85 to be evenly spread on the leveled completed surface along with the moving speed of the four-wheel differential chassis 1. When the leveling work reaches the end point position according to the planned path, the third electric push rod 86 receives a specific instruction from the robot controller, and the telescopic end of the third electric push rod 86 pushes the pressing plate 91, so that the tool holder 82 moves vertically in a straight line along the support rod 83 through the linear bearing 81 until the polyurethane pressing strip 92 contacts the cutting knife 87 respectively, driving the toothed cutting knife 87 to cut the film roll 85. After cutting, it automatically rises under the control of the robot controller, so that the film can be automatically covered on the leveled concrete surface while the construction operation is carried out, solving the problems of manual film covering and the secondary damage of the leveled ground of the concrete, greatly improving the operation efficiency of the leveling completion, reducing the on-site construction personnel requirements and construction costs. However, under the traction of the four-wheel differential chassis 1, starting from the leveling starting position, along with the synchronous ground leveling, vibrating and slurry lifting, and automatic film covering operations, the robot realizes the corresponding steering movement under the differential control of the chassis until it reaches the adjacent position to be leveled. During the whole operation process, the film covering mechanism at the tail continuously outputs the film and always adheres to the ground for automatic film covering, achieving the requirement of synchronously completing the leveling and film covering of the ground after the leveling construction.
