Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a concrete leveling and coating device. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] In the process of large-area concrete pouring, it is often necessary to have multiple people equipped with a variety of equipment, including scrapers, vibratory levelers, and covering tools. This not only requires skilled workers, but also requires multiple people to maintain good coordination and connection. It is also very easy to damage the finished product, resulting in rework and extremely low efficiency.

[0004] Current integrated tools for concrete leveling and coating consist of a board and a steel pipe. The board is used to level the concrete, and the film on the steel pipe is used to coat the concrete. This achieves both leveling and coating without requiring multiple people and various equipment, thus improving efficiency. However, the inventors discovered that when using this equipment, if there is excess concrete in the path of the concrete area to be leveled and coated, it needs to be manually removed with a shovel. After coating, the film needs to be cut manually with a hand-held cutter, which increases labor intensity, reduces work efficiency, easily damages the finished concrete, and poses certain safety hazards.

[0039] For ease of description, the use of the words "upper" and "lower" in this invention only indicates that they correspond to the upper and lower directions of the accompanying drawings and do not limit the structure. They are merely for the purpose of describing the invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention.

[0040] In this embodiment, the side where the operator is located when using the concrete leveling and covering device is defined as the front side, and the other side as the rear side.

[0041] Example 1

[0042] This embodiment provides a concrete leveling and coating device, such as... Figure 1 As shown, the device includes a frame 1, a shovel mechanism 2 on the front side of the frame 1, a leveling mechanism 3 at the bottom of the frame 1, and a film covering mechanism 4 on the rear side of the frame 1. The film covering roller of the film covering mechanism 4 is located behind the leveling mechanism 3.

[0043] The frame 1 includes two parallel columns 1-1, and a base 1-2 is fixed between the bottom ends of the two columns 1-1.

[0044] Both columns have handles 5 at the top of their front sides to facilitate the movement of the entire leveling and coating device. The handles 5 are rod-shaped and perpendicular to the columns. One end of the handle 5 is connected to the column, and the other end is covered with a handle sleeve 6. The outer surface of the handle sleeve 6 has anti-slip texture and is made of insulating material to prevent slipping, electric shock, and static electricity.

[0045] like Figures 2-3 As shown, the shovel and transport mechanism 2 includes a lifting mechanism, which is connected to the scraper assembly to drive the scraper assembly to move up and down.

[0046] The lifting mechanism includes a lifting drive component, the fixed part of which is fixed to the upper surface of the base, and the lifting part is connected to the lifting component.

[0047] The lifting drive component adopts a vertically arranged hydraulic cylinder or an electric telescopic rod, which can be configured according to actual needs by those skilled in the art.

[0048] In this embodiment, the lifting drive component is a lifting hydraulic cylinder 2-1. The cylinder body of the lifting hydraulic cylinder 2-1 is fixed on the upper surface of the base 1-2, and the piston rod end of the lifting hydraulic cylinder 2-1 is connected to the lifting component 2-2.

[0049] The lifting component 2-2 adopts a T-shaped structure, including a first lifting part arranged horizontally and a second lifting part vertically connected to the middle of the first lifting part. The second lifting part is sleeved on the outer periphery of the piston rod of the lifting hydraulic cylinder and is fixedly connected to the piston rod.

[0050] Both ends of the first lifting part are connected to one end of the lifting chain 2-3, and the other end of the lifting chain 2-3 is connected to the scraper assembly.

[0051] In this embodiment, the lifting chain 2-3 adopts a closed-loop structure. One end of the chain is connected to the end of the first lifting part through the chain groove provided in the first lifting part, and the other end is connected to the connector 2-4 through the chain groove on the connector 2-4. The connector 2-4 is fixedly connected to the scraper assembly.

[0052] The lifting chain 2-3 adopts a closed-loop structure and has a high load-bearing capacity.

[0053] The connector 2-4 is a U-shaped rod, which is fixed to the rear side of the scraper assembly. A connecting block is provided in the middle of the U-shaped rod, and a chain groove is provided on the connecting block. The lifting chain is connected to the connector 2-4 through the chain groove.

[0054] The lifting hydraulic cylinder 2-1 can drive the lifting component 2-2 to move up and down, and the lifting component 2-2 drives the scraper assembly to move up and down through the lifting chain 2-3.

[0055] The scraper assembly includes a scraper, and the scraper 2-5 adopts an L-shaped structure, including a vertically arranged first scraper part, a second scraper part is vertically arranged on the front side of the bottom end of the first scraper part, and a baffle is provided between the same side ends of the first scraper part and the second scraper part.

[0056] The rear side of the first scraper is connected to the connector 2-4. Specifically, a lifting connecting plate 2-6 is fixed to the rear side of the first scraper. Lifting connecting rods 2-7 are provided at the top and bottom of the rear side of the lifting connecting plate 2-6. The two ends of the lifting connecting rods 2-7 are slidably connected to the two columns 1-1 respectively. Specifically, the two ends of the lifting connecting rods 2-7 are rotatably connected to sliding wheels 2-9 through connecting shafts 2-8. The sliding wheels 2-9 are embedded in the sliding grooves 1-1-1 provided in the columns 1-1. Through the cooperation of the sliding wheels 2-9 and the sliding grooves 1-1-1, the lifting and lowering of the scraper is guided.

[0057] In this embodiment, the front edge of the second scraper is located behind the front end of the handle to avoid affecting the worker's grip on the handle 5.

[0058] like Figure 4 As shown, the leveling mechanism 3 includes a screed 3-1, the front side of the upper surface of the screed 3-1 being fixedly connected to the bottom surface of the upright 1-1 and the base 1-2 of the frame.

[0059] The trowel plate 3-1 is used to level concrete. To improve the leveling effect, a limiting rod 3-2 is provided on the upper surface of the trowel plate 3-1. A vibration element is fixed on the upper surface of the trowel plate 3-1 between the limiting rod 3-2 and the base 1-2. Preferably, the vibration element is a vibration motor 3-3. The vibration motor 3-3 is in contact with the limiting rod 3-2.

[0060] The limiting rod 3-2 is a cylindrical rod. In this embodiment, the direction of travel of the smearing plate 3-1 perpendicular to the working direction is defined as the width direction. The length of the limiting rod 3-2 is equal to the width of the smearing plate 3-1, and the end face of the limiting rod 3-2 is flush with the side face of the smearing plate 3-1 on the same side.

[0061] By setting the limiting rod 3-2, the vibration force can be transmitted more evenly.

[0062] The two columns 1-1 are connected to a connecting assembly at their rear top ends, and the connecting assembly is connected to a film covering mechanism 4, such as... Figures 5-7 As shown, the coating mechanism includes a bracket, which includes two parallel support rods 4-1, with the support rods 4-1 forming a set acute angle with the horizontal plane.

[0063] The support rod 4-1 includes a first rod section and a second rod section. The first rod section has a square cross-section. The first rod sections of the two support rods 4-1 are connected to the connecting assembly. The second rod section has a rectangular cross-section. The cross-sectional area of ​​the second rod section is 1 / 3 of the cross-sectional area of ​​the first rod section.

[0064] The end of the second rod near the first rod is connected to a film-coating roller 4-2. The end of the film-coating roller 4-2 is fixed to the second rod by bolts. The film-coating roller 4-2 is used to rotatably connect with the film cylinder of the film-coating 7.

[0065] The coating roller 4-2 is mounted on the second rod, making it easier to install and remove.

[0066] Behind the coating roller 4-2, a guide roller 4-3 and a pressure roller 4-4 are arranged in sequence. The two ends of the guide roller 4-3 and the pressure roller 4-4 are respectively rotatably connected to the second rod part of the two support rods 4-1.

[0067] A cutting mechanism is also provided between the two second rods, which is used to cut the film.

[0068] The cutting mechanism includes a cutter frame 4-5, which is a U-shaped structure comprising a horizontal portion and vertical portions on both sides of the horizontal portion. The vertical portions are fixedly connected to the second rod portion of the support rod 4-1. The horizontal portion is located above the guide roller 4-3. The vertical portion is provided with a groove 4-6, the axis of which is perpendicular to the axis of the support rod 4-1. A cutter assembly is slidably connected within the groove 4-6, allowing the cutter assembly to move toward and away from the guide roller 4-3. Since the film 7 passes over the guide roller 4-3 from above during use, the cutter assembly can also move toward or away from the film 7. The cutter assembly includes a cutter 4-7, with sliding shafts 4-8 at both ends. Guide wheels 4-9 at the ends of the sliding shafts 4-8 are embedded in the groove 4-6 of the vertical portion to drive the cutter 4-7 to move toward or away from the guide roller 4-3.

[0069] An elastic element is provided between the sliding shaft 4-8 and the horizontal part of the cutter frame 4-5. Preferably, the elastic element is a spring 4-10. One end of the spring 4-10 is connected to the sliding shaft 4-8, and the other end is connected to the horizontal part of the cutter frame 4-5, thereby realizing the elastic connection between the cutter assembly and the cutter frame 4-5.

[0070] The cutter assembly is connected to the cutting drive assembly, which can drive the cutter assembly to move in order to cut the film.

[0071] The cutting drive assembly includes a drive line 4-11. One end of the drive line 4-11 is fixedly connected to the sliding shaft 4-8. After passing through the adjusting bolt 4-12, the other end of the drive line 4-11 is connected to the brake lever 8 set on the handle 5 on one side.

[0072] The adjusting bolt 4-12 is threaded onto the bolt seat, which is fixed to the inner side of the vertical part of the gate cutter 4-5 and located below the slide groove 4-6.

[0073] like Figure 8 As shown, the brake lever 8 is made of a flexible material, such as rubber. When the operator holds the brake lever 8, the brake lever 8 can deform and pull the drive line. The drive line drives the sliding shaft to slide in the slide groove, thereby driving the cutter to move towards the film and cut the film. After the cutting is completed, the brake lever 8 is released. Under the action of the springs 4-10, the cutter assembly is reset and the brake lever 8 returns to its original shape.

[0074] In some other embodiments, the brake lever 8 is rotatably connected to the handle 5, which can be configured by those skilled in the art according to actual needs.

[0075] The connecting assembly includes a connecting rod 9, with both ends of the connecting rod 9 connected to two support rods 4-1 respectively.

[0076] Furthermore, the first rod portion of the support rod 4-1 is provided with an elongated hole 10, the long axis of which is arranged along the axial direction of the support rod 4-1. The end of the connecting longitudinal rod 9 is embedded in the elongated hole 10 and is slidably connected to the support rod 4-1 through the elongated hole 10. A locking element is provided between the connecting longitudinal rod 9 and the support rod 4-1. The locking element is a locking bolt 11, which is threadedly connected to the end of the connecting longitudinal rod 9. When the locking bolt 11 is rotated, the head of the locking bolt 11 is pressed against the outer side of the support rod 4-1, thereby locking and fixing the connecting longitudinal rod 9 and the support rod 4-1.

[0077] This configuration makes it easy to adjust the position of the coating mechanism 4, improving the applicability of the entire device.

[0078] The middle part of the connecting vertical rod 9 is fixedly connected to the bottom end of the connecting vertical rod 13 via the lower horizontal rod 12. The connecting vertical rod 13 is set perpendicular to the connecting vertical rod 9, and the axis of the connecting vertical rod 13 is set vertically. The top end of the connecting vertical rod 13 is connected to the rear plate 15 via the upper horizontal rod 14. A front plate 16 is fixed between the top ends of the rear sides of the two columns 1-1. A first hydraulic cylinder 17 and a second hydraulic cylinder 18 are set between the front plate 16 and the rear plate 15. The first hydraulic cylinder 17 and the second hydraulic cylinder 18 are set vertically, with the first hydraulic cylinder 17 located above the second hydraulic cylinder 18. The two ends of the first hydraulic cylinder 17 are hinged to the front plate 16 and the rear plate 15 respectively via hinge seats 19. The two ends of the second hydraulic cylinder 18 are hinged to the front plate 16 and the rear plate 15 respectively via hinge seats 19. The front and rear positions of the coating mechanism 4 can be adjusted by the first hydraulic cylinder 17 and the second hydraulic cylinder 18. At the same time, the first hydraulic cylinder 17 and the second hydraulic cylinder 18 can drive the bracket to rotate, thereby adjusting the angle of the coating mechanism 4 and improving the applicability of the entire device.

[0079] The working method of the concrete leveling and coating device in this embodiment is as follows:

[0080] A film tube is fitted onto the coating roller 4-2 with a clearance fit, allowing it to rotate freely. The coating roller 4-2 is then fixedly connected to the support rod 4-1 with bolts. The film 7 on the film tube is passed over the guide roller 4-3 from above, and then over the pressure roller 4-4 from below. The angle of the coating mechanism 4 is adjusted by the first hydraulic cylinder 17 and the second hydraulic cylinder 18. Preferably, the angle between the two support rods 4-1 of the coating mechanism 4 and the horizontal plane is 45°.

[0081] If there is no excess concrete in the path of the device corresponding to the concrete area to be covered, the scraper assembly is raised by the lifting mechanism.

[0082] Place the screed 3-1 on the concrete surface, press the film 7 onto the concrete surface with the pressure roller 4-4, start the vibrating motor 3-3, and have the worker hold the handle 5 to drive the entire leveling and film covering device along the set travel route. The screed 3-1 levels the concrete, and the film cylinder on the film covering roller 4-2 rotates to lay the film on the concrete surface, thus achieving film covering.

[0083] After the film coating is completed, the worker holds the brake lever 8 and applies a gripping load to it. The brake lever 8 deforms and pulls the drive line 4-11. The drive line 4-11 drives the cutter assembly to move toward the film 7 on the surface of the guide roller 4-3. The film is cut by the cutter 4-7. The worker releases the brake lever 8, and the cutter assembly returns to its original shape under the action of the spring 4-10.

[0084] When there is excess concrete on the travel route, the lifting mechanism is used to lower the scraper assembly until the bottom surface of the scraper assembly is flush with the bottom surface of the trowel 3-1. When the entire device is moving, the scraper 2-5 can first remove the excess concrete, and then perform leveling and covering.

[0085] Using the device of this embodiment, excess concrete can be removed by scraper assembly during the movement to facilitate subsequent leveling and coating. There is no need to manually remove excess concrete, and the coating can be cut by pulling the drive line, eliminating the need for manual cutting with a hand-held cutter. The operation is convenient and quick, reducing labor intensity, improving work efficiency, preventing damage to the finished concrete, and ensuring the safety of the operator.

[0086] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
