Description

Technical Field

[0001] The utility model relates to the technical field of concrete roughening, and particularly relates to a concrete floor roughening machine. Background Technique

[0002] A concrete floor roughening machine, as a professional construction tool, aims to create a rough texture on the surface of newly poured concrete. This treatment not only improves the adhesion between the concrete and subsequent paving materials (such as tiles, floor tiles, etc.), but also ensures the stability and durability of the paving layer. The roughening machine forms grooves with specific depth and width on the concrete surface through carefully designed processes and mechanical actions, enabling the bonding material to penetrate into the concrete base layer, thereby significantly enhancing the connection strength between the two layers of materials.

[0003] Specifically, the working methods of the roughening machine are diverse, such as using rotating blades, rollers or high-pressure water jets to process the concrete surface. For example, the 600-type multi-functional ash cleaning machine is equipped with double-roller alloy knives, and its rollers rotate driven by a speed reduction mechanism, effectively creating the required roughness on the concrete. Moreover, according to specific construction needs, the roughening machine can flexibly adjust parameters such as roller speed, blade type and depth.

[0004] In the construction of concrete roads, the roughening machine also plays an indispensable role. It can create specific textures on the road surface to improve the friction coefficient and anti-slip performance of the road. However, in actual operation, when the roughening machine needs to move or adjust its position, due to the possible change of its center of gravity, the operation becomes unstable. This problem is particularly obvious when the machine is large in volume and the central mass distribution is uneven.

[0005] Since the roughening machine needs to process the road surface in all directions during operation, its structure may need to rotate or adjust frequently. If these designs are not delicate enough, it may affect the overall stability of the machine. Especially when adjusting the position, the movement of each component of the roughening machine may break the original dynamic balance. Especially in the high-speed operation state, even a small change may cause the machine to run unstably. Content of the Utility Model

[0006] The main purpose of the utility model is to provide a concrete floor roughening machine, which can effectively solve the problems put forward in the background technique.

[0007] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] A concrete floor roughening machine includes a guiding vehicle, a sliding rail, a first moving seat and a second moving seat. The first moving seat and the second moving seat are installed at both ends of the sliding rail and are driven separately;

[0009] An installation base is installed at the upper end of the guiding vehicle, and a plurality of installation hole positions are provided at the upper end of the installation base. A connecting seat is installed at the installation hole position of the installation base, and the connecting seat is connected to the slide rail through a connecting piece. By moving the guiding vehicle along the edge of the concrete road surface, the slide rail is driven to lie across the concrete road surface;

[0010] An L-shaped frame is installed at the upper end of the second moving seat, and a driving motor is installed at the inner end of the L-shaped frame. A fixing frame is installed at the outer end of the L-shaped frame, and a rotary roughening member is installed inside the fixing frame. The output end of the driving motor is connected to the rotary roughening member. By moving the second moving seat, the rotary roughening member is moved horizontally on the concrete road surface, and the roughening operation is realized by the rotary roughening member rotating and contacting the concrete road surface.

[0011] As a further preferred solution of the present invention, an assembly pipe is installed on the seat of the first moving seat, and a plurality of counterweight blocks are sleeved on the assembly pipe. The position of the counterweight blocks is changed by the first moving seat to balance the guiding vehicle and the rotary roughening member;

[0012] As a further preferred solution of the present invention, the assembly pipe is divided into a round pipe and a blocking disc. The round pipe is fixed on the first moving seat by bolts, the blocking disc is connected to the round pipe by threads, and a rubber ring is provided at the inner hole of the counterweight block;

[0013] As a further preferred solution of the present invention, the plurality of installation hole positions are equidistantly distributed on the installation base. The round holes on the connecting seat are aligned with the installation hole positions and bolts are inserted. The connecting seat and the installation base are fixed by bolts, nuts and anti-slip gaskets. The connecting piece is a bolt, a nut and an anti-slip gasket;

[0014] As a further preferred solution of the present invention, the rotary roughening member includes a rotating shaft, a sleeve and roughening rods. A plurality of roughening rods are annularly distributed on the sleeve, the sleeve is fixed on the rotating shaft by bolts, and the rotating shaft passes through the fixing frame and is connected by a bearing assembly;

[0015] As a further preferred solution of the present invention, the L-shaped frame is fixed on the second moving seat by bolts. The cross-section of the L-shaped frame is designed in an "L" shape. The output end of the driving motor passes through the L-shaped frame and is connected to the rotating shaft of the rotary roughening member by bolts.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the present invention, by adjusting the position of the counterweight blocks, we can accurately balance the weights of the guiding vehicle and the rotary roughening member, thereby significantly enhancing the stability of the roughening machine during operation. This balance reduces the machine shaking caused by uneven weights, not only improving the work efficiency but also greatly enhancing the safety of the operation.

[0018] In addition, thanks to the independently driven first moving seat and second moving seat, the rotary scarifier can easily achieve flexible lateral movement on the concrete road surface. This design ensures that the scarifier can better adapt to various working environments and working requirements.

[0019] The position adjustment process of the counterweight is simple and fast, and can be fine-tuned in real time according to the on-site working conditions to achieve the best balance state. At the same time, the application of the bearing assembly ensures the stable rotation of the rotary scarifier, significantly reducing the risk of failures caused by unstable rotating components and further enhancing the safety of the equipment.

[0020] We have comprehensively optimized the structural design of the scarifier to make the scarifying process more stable, effectively improving the working efficiency and shortening the construction period. This scarifier is reasonably designed and has comprehensive functions, suitable for scarifying concrete floors in various different occasions, showing strong adaptability.

Detailed Description of the Preferred Embodiments

[0027] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments. Embodiment

[0028] As Figures 1 to 5 shown, we introduce a concrete floor scarifier, whose main structure includes a guiding vehicle 1, a slide rail 6, a first moving seat 7 and a second moving seat 10. These two seats are respectively installed at both ends of the slide rail 6 and have the ability of independent drive.

[0029] The top of the guiding vehicle 1 is provided with a mounting seat 2, and a plurality of mounting holes 3 are evenly distributed on the mounting seat 2. At the hole positions, we installed connecting seats 4, and these connecting seats 4 are tightly connected to the slide rail 6 through connecting pieces 5 (specifically bolts, nuts and anti-slip gaskets). When the guiding vehicle 1 travels along the edge of the concrete road surface, the slide rail 6 is guided and horizontally placed on the concrete road surface smoothly.

[0030] On the top of the second moving seat 10, we designed an L-shaped frame 12. A driving motor 11 is installed inside the L-shaped frame 12, and a fixing frame 13 is fixed on its outside. A rotating roughening member 14 is installed inside the fixing frame 13, which is a core component for roughening the concrete road surface. The output end of the driving motor 11 is directly connected to the rotating roughening member 14. Through the movement of the second moving seat 10, the rotating roughening member 14 can move horizontally on the concrete road surface and contact the concrete road surface through its rotation to realize the roughening operation.

[0031] The specific structure of the rotating roughening member 14 includes a rotating shaft, a sleeve and roughening rods. Multiple roughening rods are annularly distributed on the sleeve, and the sleeve is fixed on the rotating shaft by bolts. The rotating shaft passes through the fixing frame 13 and ensures stable rotation through a bearing assembly.

[0032] The L-shaped frame 12 is firmly fixed on the second moving seat 10 by bolts, and its cross-section is designed in an "L" shape. The output end of the driving motor 11 passes through the L-shaped frame 12 and is tightly connected to the rotating shaft of the rotating roughening member 14 by bolts. Embodiment

[0033] On the basis of Embodiment 1, we further optimized the roughening machine. In addition to the above basic structure, we added an assembly pipe 8 on the first moving seat 7. A plurality of counterweight blocks 9 are sleeved on this assembly pipe 8. By adjusting the positions of the counterweight blocks 9 on the assembly pipe 8, we can effectively balance the weights of the guiding vehicle 1 and the rotating roughening member 14 to ensure that the roughening machine is more stable during operation.

[0034] The assembly pipe 8 is divided into a round pipe and a blocking disc. The round pipe is firmly fixed on the first moving seat 7 by bolts, and the blocking disc is connected to the round pipe by threads to ensure that the counterweight blocks 9 will not fall off. In addition, a rubber ring is provided at the inner hole of the counterweight block 9, which not only increases the friction between the counterweight block 9 and the assembly pipe 8 to prevent sliding, but also plays a certain buffering role to further enhance the stability of the roughening machine.

[0035] Roughening process: The guiding vehicle 1 is started and travels along the edge of the concrete road surface, and the slide rail 6 is horizontally placed on the concrete road surface under the guidance of the guiding vehicle 1. Subsequently, the driving motor 11 inside the L-shaped frame 12 on the top of the second moving seat 10 starts to work.

[0036] The output end of the driving motor 11 drives the rotary roughening member 14 to start rotating. At this time, the second moving seat 10 moves on the slide rail 6, so that the rotary roughening member 14 moves horizontally on the concrete road surface. The roughening rod contacts the concrete road surface during rotation to achieve the roughening operation.

[0037] When adjusting the position: During the roughening process, if it is found that the weight distribution of the guiding vehicle 1 and the rotary roughening member 14 is uneven, resulting in unstable operation of the roughening machine, position adjustment is required. On the assembly pipe 8 on the first moving seat 7, adjust the position of the counterweight 9 as needed. By moving the counterweight 9, change its distribution on the assembly pipe 8 to achieve the purpose of balancing the weight. After finding the appropriate position of the counterweight 9, ensure that the counterweight 9 is fixed on the assembly pipe 8 to prevent it from sliding.

[0038] After adjusting the position of the counterweight 9, observe the stability of the roughening machine during operation. If it is found that there is still instability, the position of the counterweight 9 can be further finely adjusted to achieve the best balance state. After multiple fine adjustments, confirm that the roughening machine is stable and does not shake during operation, that is, the balance adjustment is completed.

[0039] 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 foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
