Description

Technical Field

[0001] This utility model relates to the field of concrete pouring and leveling technology, specifically a concrete pavement slurry lifting and leveling device. Background Technology

[0002] Against the backdrop of urbanization and urban development, China's municipal engineering industry, especially road engineering, has experienced rapid growth. With the substantial increase in national economy and fiscal revenue, municipal engineering is expected to maintain a high level of development in the future. Many low-grade roads in urban areas, such as secondary arterial roads or branch roads, still use concrete pavement.

[0003] In general, during the construction of concrete pavement, the smoothness of the pavement is of great significance to driving comfort and pavement drainage. The conventional construction process of concrete pavement pouring is as follows: the vibrator is used to initially vibrate until the concrete is dense, and the three rollers are used to reciprocate 5-6 times for initial leveling and grouting. Then, two people work together to use an aluminum alloy ruler to rub the concrete surface with the top elevation of the steel mold as a reference, and finally use a grinder to polish and smooth it. The manual grouting and leveling steps are particularly critical in the whole process. Its advantages and disadvantages are as follows: (1) simple tools; (2) high labor cost; (3) slow speed; (4) large human influence factors, workers are prone to fatigue, and quality problems are prone to occur. The construction process mainly controlled by manual means is prone to quality fluctuations due to mental relaxation or physical fatigue. Therefore, manual leveling with an aluminum alloy ruler is suitable for projects with short construction time and good lighting conditions. The amount of conventional concrete pavement work is approximately tens of thousands of square meters, with a daily construction progress of about 1,000 square meters. It involves continuous operation, and the efficiency of manual leveling using aluminum alloy rulers is relatively low. Workers are prone to fatigue during long hours of work, and quality control is easily relaxed.

[0028] Various improvements and variations can be made to the specific embodiments described in this utility model without departing from the scope or spirit of this utility model, which will be obvious to those skilled in the art. Other embodiments derived from this utility model description will also be obvious to those skilled in the art. This application specification and embodiments are merely exemplary.

[0029] This utility model provides a concrete pavement leveling and slurry lifting device, such as... Figure 1-3 The diagram shows the usage state of the leveling device. In a specific embodiment, concrete is poured between the parallel steel formwork 9s, and after vibration mixing, it awaits leveling by the leveling device. The leveling device includes a leveling structure 1, which is fixedly connected to a connecting frame 3 via a connecting plate 2. A vibration motor 4 for providing leveling vibration is fixedly installed on the upper part of the connecting frame 3. After the vibration motor 4 is energized, it vibrates and transmits the vibration to the leveling structure 1 through the connecting frame 3 and the connecting plate 2, so that the leveling structure 1 vibrates and levels the concrete pavement.

[0030] In addition, drive wheels 5 are provided at both ends of the leveling structure 1. The drive wheels 5 travel along the top of the steel templates 9 on both sides, driving the entire leveling device to move, saving manpower and improving leveling efficiency. The arrow in the figure indicates the forward direction of the leveling device.

[0031] In specific embodiments of this utility model, such as Figure 4 As shown, the leveling structure 1 includes a first leveling plate 11, a second leveling plate 12, and a third leveling plate 13. The first leveling plate 11 is fixedly connected to the front sidewall of the connecting plate 2 by fasteners. The second and third leveling plates 12 and 13 are respectively fixedly connected to the two transverse ends of the first leveling plate 11 and are parallel to and at the same height as the first leveling plate 11. The equal height of the first, second, and third leveling plates 11 and 13 ensures that their bottom surfaces are on the same plane, guaranteeing the best leveling effect.

[0032] Furthermore, the first plate 11 has a first fixing hole 14 at the middle position for fixing the first plate 11, and the fastener fixes the first plate 11 to the front and rear sides of the connecting plate 2 through the first fixing hole 14.

[0033] One end of the first plate 11 has a second fixing hole 15 for fixing the second plate 12, and the second plate 12 is fixedly connected to the first plate 11 by a fastener. The other end of the first plate 11 has a third fixing hole 16 for fixing the third plate 13, and the third plate 13 is fixedly connected to the first plate 11 by a fastener.

[0034] Furthermore, multiple second fixing holes 15 are evenly distributed along the transverse direction of the first plate 11 at its ends, for adjusting the transverse fixing position of the second plate 12 on the first plate 11. To improve the connection strength, multiple rows of second fixing holes 15 are provided in the vertical direction, and they correspond to each other in the vertical direction.

[0035] Multiple third fixing holes 16 are evenly distributed at the ends of the first plate 11 along the transverse direction of the first plate 11, and are used to adjust the transverse fixing position of the third plate 13 on the first plate 11. In order to improve the connection strength, multiple rows of third fixing holes 16 are provided in the vertical direction, and they correspond in the vertical direction.

[0036] By adjusting the fixed positions of the ends of the first leveling plate 11 with the second leveling plate 12 and the third leveling plate 13, the width of the entire leveling structure can be adjusted to adapt to concrete pavements of different widths, thereby improving the adaptability and efficiency of the device.

[0037] In specific embodiments of this utility model, such as Figure 5 As shown, the cross-section of the first flat plate 11 is U-shaped. The cross-sections of the second flat plate 12 and the third flat plate 13 are both L-shaped. The U-shaped first flat plate 11 is fastened to the lower part of the connecting plate 2, and the two vertical panels of the first flat plate 11 are fixedly connected to the connecting plate 2.

[0038] The first fixing hole 14 is located on the middle vertical panel of the first flat plate 11, and the second fixing hole 15 and the third fixing hole 16 are located on the vertical panels at both ends of the first flat plate 11. Figure 2 As shown, along the leveling forward direction, the second leveling plate 12 and the third leveling plate 13 are fixed on the rear vertical panel of the first leveling plate 11.

[0039] The second flat plate 12 and the third flat plate 13 have fixing holes corresponding to the second fixing hole 15 and the third fixing hole 16, respectively.

[0040] Furthermore, the transverse panels of the first flat plate 11, the second flat plate 12, and the third flat plate 13 are flush with the top of the steel formwork 9 to ensure the best concrete leveling effect.

[0041] In a specific embodiment of this utility model, a vibration damping block 6 is provided between the connecting plate 2 and the connecting frame 3. The vibration damping block 6 can protect the vibration motor 4 and prevent the leveling structure from colliding with the steel template 9 under rigid connection conditions, which would damage the vibration motor 4. In addition, it is also beneficial to vibration slurry lifting and increasing the residual vibration frequency. In this embodiment, the vibration damping block is a columnar structure, and at least one vibration damping block is provided between the connecting plate 2 and the connecting frame 3.

[0042] In a specific embodiment of this utility model, a limiting rod 7 is fixedly provided at the end of the second leveling plate 12 and the third leveling plate 13 away from the fixed end. The limiting rod 7 is located inside the steel template 1 and is used to cooperate with the steel template 9 to limit the movement of the leveling device during its forward movement, thereby preventing the leveling device from deviating from its intended path.

[0043] In a specific embodiment of this utility model, a handrail 8 is fixedly installed on the connecting frame 3. A controller is installed on the handrail 8 to control the operation of the leveling device.

[0044] A vibration damping structure is installed at the connection between the drive wheel 5 and the leveling structure 1 to reduce the impact of vibration on the drive wheel 5. After the vibration of the vibrating motor is transmitted to the leveling structure 1, it will be further transmitted to the drive wheel. The vibration damping structure can greatly reduce the impact of vibration on the drive wheel structure and reduce the impact of vibration on the movement of the drive wheel.

[0045] In addition, it can ensure that the leveling structure can make contact with the concrete in the middle through its own weight and downward pressure, so as to achieve a good leveling effect.

[0046] The above description is merely an illustrative embodiment of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model shall fall within the scope of protection of this utility model.
